End of the novel Essay Example for Free

End of the novel Essay This is similar to Victors pursuit for glory, as both men (Victor and Walton) are putting the life of themselves and other men in danger by continuing to try and achieve their ambition. From Victors above words we can see that he is still motivated to seek revenge on the monster, despite the danger to his life. He also attempts to put the life of others in danger, as he asks Walton to murder the monster if he gets a chance:  If I do (die), swear to me, Walton, that (the monster) shall not escape; that you seek him, and satisfy my vengeance in his death.   (Volume 3, Chapter 7, p212) When Victor enters the novel, he is portrayed as a noble and kind person who is capable of both love and friendship. He has strong ambition and eager to learn. However, one gets the impression that when he starts to create life, he is trying to take the role of God, and becomes obsessed with gaining glory and power so much, that he forgets the importance of love and family. Victor also fails to care for the monster, which in my opinion is highly monstrous as it just like abandoning a new born baby. Furthermore, Victor acts selfishly in many occasions throughout the play. He decides to create a female companion for the monster, to stop the monster chasing him. But he goes against his promise when he thinks about what the world will think of him, if a race of monsters attacks the world. Everything Victor does is centred on himself and he only thinks about what benefit it would be to himself, when he considers an action. Now that I have considered Victor as a character, I will now examine the monster. The monster starts off his life as an innocent creature; however his abnormal figure and demented shape caused people to be scared of him and reject him. When the monster walked into an old mans home to obtain food and shelter, the old man:  -turned on hearing a noise; and, perceiving (the monster), shrieked loudly, and, quitting the hut, ran across the fields.  (Volume 2, Chapter 3, p108) All the man had to see was monsters figure to make him run away without any enquiry. This suggests that the creatures look posed a threat to everyone who saw him, and led to him being alienated from society.  However the monster is quite kind to start off with. While he was observing the De Lacy family, he demonstrates his kind gestures by gathering a great pile of wood for the De Lacy family to use as firewood. He also put their well being before his starvation, as he stopped stealing a part of their store for (his) own consumption when he found out that it inflicted pain on the cottagers. During the beginning period the monster spends with the De Lacy family, he perceives that the words they spoke sometimes produced pleasure or pain, smiles or sadness, in the minds and countenances of the hearers. He too wanted to be able to interact in this way and ardently desired to become acquainted with speech. This shows that the monster is eager to learn and wants to become just like other humans. Once the monster has mastered the use of speech, his desire to be like humans motivated him to enter the house of the De Lacy family, and speak to the blind old man when he was left alone at the cottage. This shows that the monster has some wit and cleverness as he selects a person who cant judge him by his figure, but his personality and speech. However, whilst he is talking to the blind old man, the rest of the De Lacy family return home and were shocked by the appearance of the monster to such an extent that Felix, a male member of the De Lacy family, beat the monster violently with a stick using supernatural force. It is this mistreatment of the monster that sparks a deadly hatred within himself for his creator. The monster had received abuse from the De Lacy family after he had helped them, all because of the way that Victor had made him look, and the fact that he had failed to protect him. It is this anger that makes the monster monstrous by personality and drives him to kill William (Victors younger brother):  Frankenstein! You belong then to my enemyto him towards whom I have sworn eternal revenge; you shall be my first victim.  (Volume 2, Chapter 8, p144) The monster also seems to be jealous of Victor, as he knows that he can never have love and relationship like him and other humans because of the way he looks. We know this because the monster frames Justine for murder of William, as he knew he could never possess anything as beautiful as her. And it is this feeling that brings the monster to demand Victor to make a creature of another sex, but as hideous as himself. From this, we can see all that the monster wants is a bit of love and companionship, to make him lead a life which is similar to humans. However Victor cheats the monster by first agreeing to create the female monster, but then tearing (her) to pieces in front the monster at the final stages of her production. This upsets the monster as Victor has effectively destroyed the monsters only chance of love in front of his eyes. This antagonism caused the monster to become monstrous once again, as he murders both Henry Clerval and Elizabeth (now Victors wife): -what I now held in my arms had ceased to be the Elizabeth whom I had loved and cherished. The murderous mark of the fiends grasp was on her neck, and the breath had ceased to issue from her lips. (Volume 3, Chapter 6, p199)  Despite this, the monster does illustrate some humane characteristics towards the end of the novel. He presents great grievance for the death of Victor, and heartfelt remorse for his malicious actions:  Oh, Frankenstein! generous and self-devoted being! What does it avail that I now ask thee to pardon me? I, who irretrievably destroyed thee by destroying all thou lovedst.

Development of College Announcement Notification System

Development of College Announcement Notification System Chapter 1: Introduction Introduction This project proposal is created to propose an IT solution to the student of Sunway University. The main point that the author want to highlight is regarding the efficiencies for student in Sunway University. An example, inefficiencies that occur in posting the announcement that is post on the website or in the notice board, it is hard to inform to the student and also the staff may also forget to post the announcement that will inconvenient for the student itself. In order to solve those problems, the author proposed to create a website as a third party for the staff to post the announcement. The author feel that only a website is very simple and common nowadays, so to improve the effectiveness and give more efficiency, a SMS (Short Messaging Service) feature is added to the system. Every announcement is posted by the SCT Staffs in the website, a SMS notification will be sent to the student that already registered to the website. The content of the SMS just a brief notification abou t the title of the event, venue and time, for more brief detail the students can refer to the website. Other way to notify the students is used Email as an instant notifier, but consider using email as an instant notifier is not really effective because students didnt open their email every day but using the SMS as the instant notifier to notify the students are more effective because most of the student is own and bring their own cell phone, therefore the MS as an instant notifier is more appropriate. Since the advancement of the technology nowadays, using this system will help in reduce the paper usage. Project Objective To give efficiencies for staff of Sunway University who want to post announcement. To use SMS as an instant notifier, for example every announcement post on the website the student will receive a SMS about the annoncement. In long term of view, this system will help in notify student about things that happen in college. Project Scope To become the most useful media for announcement notification. When the system is run it involves the Sunway University students and staffs that want to use the service. The user of the system should be students of Sunway University and staffs. All users that want to use the system have to become member. Methodology Methodology is a formalized approach to implement the SDLC (System Development Life Cycle). There are many different systems development methodologies, and each one is unique based on the order and focus it places on each SDLC phase. Some methodologies are formal standards used y government agencies, while others have been developed by consulting firms to sell to client. Many organizations have internal methodologies that have been honed over the years, and they explain exactly how each phase of the SDLC is to be performed in that company. There are many ways to categorize methodologies. One way is looking at whether they focus on business process or the data that support the business. There are three types of system development methodologies, it is called Structured Design, RAD (Rapid Application Development), and Agile Development. Types of Software Development Methodologies Structured Design This is the first type of system development, it is introduced in 1980s. This methodology adopts the formal step by step approach to the SDLC, it moves logically from one phase to another phase. Waterfall Model This is the original structured design of methodology, with this methodology, the analyst and users proceed in sequence from one phase to the next phase. The key deliverables for each phase are typically very long and are presented to the project sponsor for approval as the project moves from phase to phase. This methodology is referred to as waterfall development because it moves forward from phase to phase in the same manner as a waterfall. Advantages of using waterfall model: It identifies system requirements long before programming begins It minimizes changes to the requirements as the project proceeds. Disadvantages of using waterfall model: The design must be completely specified before programming begins This model required significant rework, if there is a changes in the business environment, in order to going back to the initial phase need to go through each of the subsequent phase in return. Parallel Development This model of methodology attempts to address the problem of long delay between analysis phase and the delivery of the system. Instead of doing design and implementation in sequence, it performs a general design for the whole system and then divides the project into a series of distinct subprojects that can be designed and implemented in parallel. Once all subprojects are complete, there is a final integration of the separate pieces, and the system is delivered. Advantage of using parallel model: It can reduce the schedule time to deliver a system There is less chance of changes in the business environment causing rework Disadvantage of using parallel model: The approach still suffers from problem caused by paper documents It adds new problem, sometimes subprojects arent completely independent; design decisions made in one subproject may affect another subprojects Phased Development In this model, the overall system is divided into a series of version that are developed sequentially. The analysis phase identifies the overall system concept, and the project team, users and system sponsors then categorize the requirement into a series of version. Advantage of using phased model: Quickly getting a useful system into the hands of the users While the system does not perform all the functions the users need at first, it does begin to provide business value sooner than if the system were delivered after completion, as is the case with waterfall or parallel methodology. Disadvantage of using phased model: The users begin to work with the systems that are intentionally incomplete, it is critical to identify the most important and useful feature and include them in the first version, while managing users expectation along the way. Prototyping In this model, it performs the analysis, design and implementation phases concurrently, and all the three phases are performed repeatedly in a cycle until the system is completed. In this methodology, the basics of analysis and design are performed, and work immediately begins on a system prototype, a â€Å"quick and dirty† program that provides a minimal amount of features. Advantage of using prototyping model: It is very quickly provides a system for the users to interact with, even it is not ready for widespread organizational use at first. Reassure the users that the project team is working on the system Helps to more quickly refine real requirements rather than attempting to understand a system specification on paper, the user can interact with the prototype to better understand what it can do and cannot do. Disadvantage of using prototyping model: Its fast paced system releases challenge attempts to conduct careful, methodical analysis. This can cause problems in the development of complex systems because fundamental issues and problems are not recognized until well into the development process. Software Development Methodology Comparison After do research about the types of methodology that is appropriate to be used into the project. The author compared the 4 types of methodology that is compatible with the current development. The following table is the result of using the described methodology to the project. System Characteristic Waterfall Parallel Phased Prototyping Unclear User Requirement Poor Poor Good Excellent Unfamiliar Technology Poor Poor Good Poor Complexity of the System Good Good Good Poor Reliability of the System Good Good Good Poor Short Time Schedule Poor Good Excellent Excellent Schedule Visibility Poor Poor Excellent Excellent Table 1 Methodology Comparison Selecting the appropriate Methodology According to the project objective that the author proposed, author analyze each methodology that is already been researched. The author decides to use the Phased Methodology. The main reason on why the author uses this methodology is because the author would develop this system all by himself and the project will be easier to be built phase by phase. Other considerations in choosing this model are: User Requirement: the requirement of the system is clear, which is to address the problem of inefficiency and ineffectiveness of conventional way in notify the student for announcement. Familiarity with Technology: for designing the website, PHP, VB.Net language technology is going to be used, since it is still in area of the author expertise. System Complexity: the complexity of this project is at medium level, since the author familiar with the technology used in the project so it is not really difficult. However the author still need to do research on certain area of technology, for this case the knowledge of SMS gateway, and how to integrate the web based system with the SMS gateway. Duration: the duration of developing the project is approximately 4 months in order to fully complete the project. Development Method: it is a web based application that is built using the PHP, and VB.NET as the programming language. Area of Research Certain areas that we research for this project are: How to create easy and manageable database system? What is SMS (Short Message Service) portal and SMS (Short Message Service) gateway? How to integrate web based system with SMS portal? How to create easy and manageable database system? This part is one of the crucial parts in order to make a good web based application system. Therefore, creating an easy and manageable database system is really important. The database system that the author used to manage the College Announcement System web based application is MySQL. Several reasons become the consideration of choosing the MySQL software are, first reason is because the main programming language system that the author built is using the PHP technology, and PHP language has an integrated connector that able to connect it to SQL. Second reason, MySQL is open source software so it is free for download, it is will help in determining the project cost development. There is other software which is better than MySQL but looked back at the scope of the project; this is just an undergraduate project, then the author decides that using MySQL software is a wiser choice. The third reason, the author already took the MySQL subject during the study in Sunway University College, which is still in the author expertise. However, if this system wants to be implemented into the real organization, further study to create easy and manageable design is needed. When the project is already on the run, this would be very beneficial in doing maintenance of the application system. How to integrate the Web based System with SMS portal? As most people known that SMS is the most famous service that a mobile phone give. It is a service where the users able to send short text message from a mobile phone to another mobile phone. Basically the SMS would not work with just the mobile phone itself, it I because the Mobile Phone Network Operator that give the service so the SMS can be delivered to the recipient by the help of the mobile phone device as the medium to type the message. The SMS can travel all the way from the sender device to the recipient device must go through a pathway through a network called SMSC (Short Message Service Centre). SMSC works as a hardware that stores the SMS that is sent from a mobile phone then forward it again to the recipient. From the early of 1990s, the era when the first SMS is sent through the network using the mobile phone device. Nowadays with the advancement of the technology, SMS not only can be done through using mobile phone but can be integrated in other application such as web based application system, using the SMS gateway technology. However, the SMS that is sent still have to go through SMSC, which is still needed to use the SIM Card that is given by the mobile network operator. SMS gateway act as a bridge the platform that cannot use the mobile phone SIM Card to use the mobile service by using the GSM modem, in this case the mobile service is to send the SMS. The mobile SIM Card will be inserted into the GSM modem. GSM modem will act as the third party to connect to the SMSC. The web based application store the message that will be sent into the database, and the GSM will retrieve the data from the database and ready to send the SMS to the destination number. The basic function of SMS and e mail is the same, for email the sender need to enter the destination email and for SMS the sender need to enter the destination phone number. The difference is why SMS is more popular than email is because it is mobile and user can send and receive SMS wherever they are. The mobile advantage of using SMS is the reason that makes the author choose the SMS application system to be added into the College Announcement Notification system instead of using email. Another reason the author choose to use SMS is because most of the students in Sunway didnt have mobile phone that can handles in receiving and sending email, but most of the students have mobile phone that enable them to send and receive SMS. Therefore, using the SMS as additional software into College Announcement Notification system is the best choice, and the author also learn to use the GSM modem and the implementation of it into the system. Software / Hardware Requirements In order to make this project successful there are some hardware and software which is required to use in order to complete the project are: Software and Hardware requirement to develop the system. Software: SQL YOG: is the database software that the author chose to be implemented inside the College Announcement Notification system. SQL Yog had the user friendly interface and it is open source software. XAMPP: this software is applied as the localhost to compile the web based application. Adobe Dreamweaver: is the software that makes it easier to edit the coding for PHP, JAVA. Hardware: PC (with mouse, keyboard, monitor) / laptop with minimum specification: Intel Core Duo processor(1.66Hz), 1GB RAM, 60GB 5400 RPM HDD Software and Hardware Requirement to run the system. User Side Hardware Requirement: PC (with mouse, keyboard, monitor) / laptop with minimum specification: Intel Core Duo processor(1.66Hz), 1GB RAM, 60GB 5400 RPM HDD User Side Software Requirement: Web browser: Mozilla Firefox, IE, Google Chrome, etc Server Side Hardware Requirement: PC (with mouse, keyboard, monitor) / laptop with minimum specification: Intel Core Duo processor(1.66Hz), 1GB RAM, 60GB 5400 RPM HDD GSM Modem Server Side Software Requirement: Adobe Dreamweaver SQL Yog Web Browser: Mozilla Firefox, IE, Google Chrome, etc XAMPP Server side software requirement is needed to do the regular maintenance on the system. The development software might be needed to fix error that might be occurred when the system on the run. Chapter 2: Literature Review Literature Review Literature Review is a critical look at the existing research that is significant to the work that is currently undergo. The author currently did a project; College Announcement Notification System is the project. College Announcement Notification System is a web based application system, which is proposed as a solution to Sunway University College regarding the poor information flow in Sunway University College especially School of Computer Technology. The author chose to propose the solution only to School of Computer Technology because of the course that currently taken is under it. College Announcement Notification System is a web based application, it is hoped the system would work perfectly and increasing the information flow within School of Computer Technology (SCT). The users of the system able to access the College Announcement Notification System via laptop or PC, as long there is an internet connection. The author think if it just a normal website, there is no uniqueness that makes my project different than the others. After doing research, the author decided to add the SMS feature as the instant notification system. Integrate the system with SMS feature; means need to deal with SMS gateway. The author aware that using the SMS feature is almost the same like adding the Email as the instant notification where the system is able to send automatically the posted announcement that is already posted in the website. Email is an electronic mail that worked same like a normal mail, where the users need to write the content of the letter, after that the address of the recipient is a must for the users to add. Email enables users to send and receive electronically over the internet. SMS and Email basically is the same, it contains text and to send it need to know the exact recipient email address for email and phone number for SMS. There are many email server company that is give services for the users to send and receive email such as Hotmail, Yahoo Mail, Go ogle Mail, etc. There is also an application that handles email such as Microsoft Outlook. Some advantages that email could give are emails is free for users to use like send and receive mail, it can contains richer message contents than the conventional mail did. However from the advantages that an email, there are also a few disadvantages of emails. With the advancement of the technology nowadays, the previous email only can sent the words but nowadays, users can sent not only words but can attach richer media such as picture, video, file, etc. This advantages of email were misused by some people, it enable them to send virus, malicious software, spam that can harm the recipients PC or laptop. In order to overcome this security issue, the email provider companies try many ways to increase the security but the spammer can overcome the security and still sent the spam email that may contain virus and malicious software. Using the email as an instant notification to the College Announcement Notification System is a good choice but users may not open their own email daily, usually users open their email whenever the feel like to open it. Therefore, the author proposed to use the SMS system as the instant notification. There are few reasons that become the considerations of choosing SMS to be implemented. First reason, the project is a notification system so SMS is the best choice because after the sender sent it then the recipients received it in instant. Second reason, if using email the recipients of the email need to open their own laptop or PC, and then open the email service web page, it will takes time and not instant. Most of the students nowadays had their own mobile phone and they carry their mobile phone everywhere they go, so it is one of the reason why the author choose to use SMS as an instant notification. Mobile phone user aware that open a SMS is faster than open an Email. Nowadays, ma ny mobile phone producers now produced a new mobile phone that can handles in send or receive an email. However mobile phone that can handles send and receive email is still too expensive for the most of the mobile phone users only a few that can afford that. But if the SMS only, most of the mobile phone users able to send and receive that because it is the basic function that the mobile phone offer. SMS (Short Messaging Service) As most people known, SMS is a protocol used in communication that gives way to exchange of short message from one mobile phone to another mobile phone (tech-faq.com, 2009). Nowadays mobile phone takes an important part because it provides connections to the others that in the past impossible to do. The main usage of the mobile phone is to enable users to make a phone call wherever and whenever they are, beside used to call others; other main function of mobile phone that is growing rapidly is the usage of SMS service. SMS stands for Short Message Service. It is a technology that enables the sending and receiving of messages between mobile phones. SMS first appeared in Europe in 1992. It was included in the GSM (Global System for Mobile Communications) standards right at the beginning. Later it was ported to wireless technologies like CDMA and TDMA. The GSM and SMS standards were originally developed by 3GPP (Third Generation Partnership Project) is responsible for the development and maintenance of the GSM and SMS standards. As suggested by the name Short Message Service, the data that can be held by an SMS message is very limited. One SMS message can contain at most 140 bytes (1120 bits) of data, so one SMS message can contain up to: 160 characters if 7-bit character encoding is used. (7-bit character encoding is suitable for encoding Latin characters like English alphabets.) 70 characters if 16-bit Unicode UCS2 character encoding is used. (SMS text messages containing non-Latin characters like Chinese characters should use 16-bit character encoding.) SMS text messaging supports languages internationally. It works fine with all languages supported by Unicode, including Arabic, Chinese, Japanese and Korean. Besides text, SMS messages can also carry binary data. It is possible to send ringtones, pictures, operator logos, wallpapers, animations, business cards (e.g. VCards) and WAP configurations to a mobile phone with SMS messages. One major advantage of SMS is that it is supported by 100% GSM mobile phones. Almost all subscription plans provided by wireless carriers include inexpensive SMS messaging service. Unlike SMS, mobile technologies such as WAP and mobile Java are not supported on many old mobile phone models. (developershome.com, 2008) Usage of SMS As the mobile voice communication market approaches saturation, carriers are focusing on messaging as crucial value -added service to garner more mobile subscribers and generate greater market revenue. Specifically, SMS (Short Messaging Service) is emerging as one of the most important asynchronous communication that carriers provide. It is projected that in 2009 U.S subscribers will send over 126 billion messages via their mobile phone device, generating $8.6 billion revenues (Deng, Sun, Turner, Prince, 2008). Nowadays, people are presented with a wide variety of communication media such as email, instant messaging (IM), etc. To date, most researchers have focused on the use of SMS by teenager and young adult. Recently as SMS become the needs in our daily lives, older people also recognized the convenience of using SMS. It has been reported that over 74% of the mobile phone users worldwide is using SMS text messaging (Deng, Sun, Turner, Prince, 2008). How does the SMS works? Even if you are not talking on your cell phone, your phone is constantly sending and receiving information. It is talking to its cell phone tower over a pathway called acontrol channel. The reason for this chatter is so that the cell phone system knows which cell your phone is in, and so that your phone can change cells as you move around. Every so often, your phone and the tower will exchange a packetof data that lets both of them know that everything is OK. Your phone also uses the control channel for call setup. When someone tries to call you, the tower sends your phone a message over the control channel that tells your phone to play itsringtone. The tower also gives your phone a pair of voice channel frequencies to use for the call. The control channel also provides the pathway for SMS messages. When a friend sends you an SMS message, the message flows through the SMSC, then to the tower, and the tower sends the message to your phone as a little packet of data on the control channel. In the same way, when you send a message, your phone sends it to the tower on the control channel and it goes from the tower to the SMSC and from there to its destination. (howstuffworks.com, 2005) The SME (Short Message Entity), which is typically a mobile phone or a GSM modem, can be located in the fixed network or a mobile station, receives and sends short messages. The SME was sent to the SMSC.TheSMSC (Short Message Service Center)is the entity which does the job of store and forward of messages to and from the mobile station. After receiving the SME, then SMSC sent the SME to the SMS GMSC. TheSMS GMSC(SMS gateway MSC (Mobile Switching Center)) is a gateway so that MSC that can also receive short messages. The gateway MSC is a mobile networks point of contact with other networks. On receiving the short message from the short message center, GMSC uses the SS7 network to interrogate the current position of the mobile station form the HLR, the home location register. HLRis the main database in a mobile network. It holds information of the subscription profile of the mobile and also about the routing information for the subscriber, i.e. the area (covered by a MSC) where the mobile is currently situated. The GMSC is thus able to pass on the message to the correct MSC. MSC(Mobile Switching Center) is the entity in a GSM network which does the job of switching connections between mobile stations or between mobile stations and the fixed network. AVLR(Visitor Location Register) corresponds to each MSC and contains temporary information about the mobile, information like mobile identification and the cell (or a group of cells) where the mobile is currently situated. Using information from the VLR the MSC is able to switch the information (short message) to the corresponding BSS (Base Station System, BSC + BTSs), which transmits the short message to the mobile. The BSS consists of transceivers, which send and receive information over the air interface, to and from the mobile station. This information is passed over the signaling channels so the mobile can receive messages even if a voice or data call is going on. (logixmobile.com) How to send SMS using a computer? After done some research about how the SMS works, there are several ways in sending SMS using computer, they are (developershome.com, 2008): Connect a mobile phone or GSM/GPRS modem to a computer / PC. Then use the computer / PC and VB commands to instruct the mobile phone or GSM/GPRS modem to send SMS message. Connect the computer / PC to the SMS center (SMSC) or SMS gateway of a wireless carrier or SMS service provider. Then send SMS messages using a protocol / interface supported by the SMSC or SMS gateway. Connection between mobile phone or GSM/GPRS modem to computer using VB command for sent SMS A GSM/GPRS modem is a wireless modem that works with GSM/GPRS wireless networks. A wireless modem is similar to a dial-up modem. The main difference is that a wireless modem transmits data through a wireless network whereas a dial-up modem transmits data through a copper telephone line. To send SMS messages, first place a valid SIM card from a wireless carrier into a mobile phone or GSM/GPRS modem, which is then connected to a computer. There are several ways to connect a mobile phone or GSM/GPRS modem to a computer. For example, they can be connected through a serial cable, a USB cable, a Bluetooth link or an infrared link. The actual way to use depends on the capability of the mobile phone or GSM/GPRS modem. After connecting a mobile phone or GSM/GPRS modem to a computer, you can control the mobile phone or GSM/GPRS modem by sending instructions to it. The instructions used for controlling the mobile phone or GSM/GPRS modem are called by using VB commands. The above figure showed the process of sending SMS using the VB application. In this case, the system that the author developed is using PHP that act as the third party to store the announcement data inside the database. After finish with the stored announcement, VB application is used to instruct the GSM modem to send SMS. As shown in the figure above, VB application will retrieve the stored data that will be sent as SMS. Then after retrieving the data, it will be sent to through SMS gateway until it arrived in the hand of the recipient. One of the benefits from using the VB application to send SMS is users will have a very reliable notification system, because before sending SMS intended recipient can be configured so it is received at the intended recipient. Using a mobile phone or GSM/GPRS modem to send SMS messages has a major drawback, which is the SMS sending rate is too low. Only 6-10 SMS messages can be sent per minute (when the SMS over GSM mode is used). The performance is not affected by the connection between the computer and the mobile phone or GSM/GPRS modem (i.e. the SMS sending rate is about the same no matter the mobile phone or GSM/GPRS modem is connected to the computer through a serial cable, USB cable, Bluetooth link or infrared link) and does not depend on whether a mobile phone or GSM/GPRS modem is used (i.e. the SMS sending rate is about the same no matter a mobile phone or a GSM/GPRS modem is used). The determining factor for the SMS sending rate is the wireless network. (developershome.com, 2008) Send SMS from Computer through SMS Gateway The way for sending SMS messages from a computer through a mobile phone or GSM/GPRS modem has a major limitation, which is the SMS sending rate is too low. If you need a high SMS sending rate, obtaining a direct connection to the SMS center (SMSC) or SMS gateway of a wireless carrier is necessary. It can be difficult for small businesses or individual application developers to obtain a direct connection to the SMSC or SMS gateway of a wireless carrier since a wireless carrier may only provide such service to those who have huge SMS traffic. Buying SMS messages in bulk means the total fee will be very high (although the fee per SMS message will be low).

Types of Software Development Methodologies Structured Design This is the first type of system development, it is introduced in 1980s. This methodology adopts the formal step by step approach to the SDLC, it moves logically from one phase to another phase. Waterfall Model This is the original structured design of methodology, with this methodology, the analyst and users proceed in sequence from one phase to the next phase. The key deliverables for each phase are typically very long and are presented to the project sponsor for approval as the project moves from phase to phase. This methodology is referred to as waterfall development because it moves forward from phase to phase in the same manner as a waterfall. Advantages of using waterfall model: It identifies system requirements long before programming begins It minimizes changes to the requirements as the project proceeds. Disadvantages of using waterfall model: The design must be completely specified before programming begins This model required significant rework, if there is a changes in the business environment, in order to going back to the initial phase need to go through each of the subsequent phase in return. Parallel Development This model of methodology attempts to address the problem of long delay between analysis phase and the delivery of the system. Instead of doing design and implementation in sequence, it performs a general design for the whole system and then divides the project into a series of distinct subprojects that can be designed and implemented in parallel. Once all subprojects are complete, there is a final integration of the separate pieces, and the system is delivered. Advantage of using parallel model: It can reduce the schedule time to deliver a system There is less chance of changes in the business environment causing rework Disadvantage of using parallel model: The approach still suffers from problem caused by paper documents It adds new problem, sometimes subprojects arent completely independent; design decisions made in one subproject may affect another subprojects Phased Development In this model, the overall system is divided into a series of version that are developed sequentially. The analysis phase identifies the overall system concept, and the project team, users and system sponsors then categorize the requirement into a series of version. Advantage of using phased model: Quickly getting a useful system into the hands of the users While the system does not perform all the functions the users need at first, it does begin to provide business value sooner than if the system were delivered after completion, as is the case with waterfall or parallel methodology. Disadvantage of using phased model: The users begin to work with the systems that are intentionally incomplete, it is critical to identify the most important and useful feature and include them in the first version, while managing users expectation along the way. Prototyping In this model, it performs the analysis, design and implementation phases concurrently, and all the three phases are performed repeatedly in a cycle until the system is completed. In this methodology, the basics of analysis and design are performed, and work immediately begins on a system prototype, a â€Å"quick and dirty† program that provides a minimal amount of features. Advantage of using prototyping model: It is very quickly provides a system for the users to interact with, even it is not ready for widespread organizational use at first. Reassure the users that the project team is working on the system Helps to more quickly refine real requirements rather than attempting to understand a system specification on paper, the user can interact with the prototype to better understand what it can do and cannot do. Disadvantage of using prototyping model: Its fast paced system releases challenge attempts to conduct careful, methodical analysis. This can cause problems in the development of complex systems because fundamental issues and problems are not recognized until well into the development process. Software Development Methodology Comparison After do research about the types of methodology that is appropriate to be used into the project. The author compared the 4 types of methodology that is compatible with the current development. The following table is the result of using the described methodology to the project. System Characteristic Waterfall Parallel Phased Prototyping Unclear User Requirement Poor Poor Good Excellent Unfamiliar Technology Poor Poor Good Poor Complexity of the System Good Good Good Poor Reliability of the System Good Good Good Poor Short Time Schedule Poor Good Excellent Excellent Schedule Visibility Poor Poor Excellent Excellent Table 1 Methodology Comparison Selecting the appropriate Methodology According to the project objective that the author proposed, author analyze each methodology that is already been researched. The author decides to use the Phased Methodology. The main reason on why the author uses this methodology is because the author would develop this system all by himself and the project will be easier to be built phase by phase. Other considerations in choosing this model are: User Requirement: the requirement of the system is clear, which is to address the problem of inefficiency and ineffectiveness of conventional way in notify the student for announcement. Familiarity with Technology: for designing the website, PHP, VB.Net language technology is going to be used, since it is still in area of the author expertise. System Complexity: the complexity of this project is at medium level, since the author familiar with the technology used in the project so it is not really difficult. However the author still need to do research on certain area of technology, for this case the knowledge of SMS gateway, and how to integrate the web based system with the SMS gateway. Duration: the duration of developing the project is approximately 4 months in order to fully complete the project. Development Method: it is a web based application that is built using the PHP, and VB.NET as the programming language. Area of Research Certain areas that we research for this project are: How to create easy and manageable database system? What is SMS (Short Message Service) portal and SMS (Short Message Service) gateway? How to integrate web based system with SMS portal? How to create easy and manageable database system? This part is one of the crucial parts in order to make a good web based application system. Therefore, creating an easy and manageable database system is really important. The database system that the author used to manage the College Announcement System web based application is MySQL. Several reasons become the consideration of choosing the MySQL software are, first reason is because the main programming language system that the author built is using the PHP technology, and PHP language has an integrated connector that able to connect it to SQL. Second reason, MySQL is open source software so it is free for download, it is will help in determining the project cost development. There is other software which is better than MySQL but looked back at the scope of the project; this is just an undergraduate project, then the author decides that using MySQL software is a wiser choice. The third reason, the author already took the MySQL subject during the study in Sunway University College, which is still in the author expertise. However, if this system wants to be implemented into the real organization, further study to create easy and manageable design is needed. When the project is already on the run, this would be very beneficial in doing maintenance of the application system. How to integrate the Web based System with SMS portal? As most people known that SMS is the most famous service that a mobile phone give. It is a service where the users able to send short text message from a mobile phone to another mobile phone. Basically the SMS would not work with just the mobile phone itself, it I because the Mobile Phone Network Operator that give the service so the SMS can be delivered to the recipient by the help of the mobile phone device as the medium to type the message. The SMS can travel all the way from the sender device to the recipient device must go through a pathway through a network called SMSC (Short Message Service Centre). SMSC works as a hardware that stores the SMS that is sent from a mobile phone then forward it again to the recipient. From the early of 1990s, the era when the first SMS is sent through the network using the mobile phone device. Nowadays with the advancement of the technology, SMS not only can be done through using mobile phone but can be integrated in other application such as web based application system, using the SMS gateway technology. However, the SMS that is sent still have to go through SMSC, which is still needed to use the SIM Card that is given by the mobile network operator. SMS gateway act as a bridge the platform that cannot use the mobile phone SIM Card to use the mobile service by using the GSM modem, in this case the mobile service is to send the SMS. The mobile SIM Card will be inserted into the GSM modem. GSM modem will act as the third party to connect to the SMSC. The web based application store the message that will be sent into the database, and the GSM will retrieve the data from the database and ready to send the SMS to the destination number. The basic function of SMS and e mail is the same, for email the sender need to enter the destination email and for SMS the sender need to enter the destination phone number. The difference is why SMS is more popular than email is because it is mobile and user can send and receive SMS wherever they are. The mobile advantage of using SMS is the reason that makes the author choose the SMS application system to be added into the College Announcement Notification system instead of using email. Another reason the author choose to use SMS is because most of the students in Sunway didnt have mobile phone that can handles in receiving and sending email, but most of the students have mobile phone that enable them to send and receive SMS. Therefore, using the SMS as additional software into College Announcement Notification system is the best choice, and the author also learn to use the GSM modem and the implementation of it into the system. Software / Hardware Requirements In order to make this project successful there are some hardware and software which is required to use in order to complete the project are: Software and Hardware requirement to develop the system. Software: SQL YOG: is the database software that the author chose to be implemented inside the College Announcement Notification system. SQL Yog had the user friendly interface and it is open source software. XAMPP: this software is applied as the localhost to compile the web based application. Adobe Dreamweaver: is the software that makes it easier to edit the coding for PHP, JAVA. Hardware: PC (with mouse, keyboard, monitor) / laptop with minimum specification: Intel Core Duo processor(1.66Hz), 1GB RAM, 60GB 5400 RPM HDD Software and Hardware Requirement to run the system. User Side Hardware Requirement: PC (with mouse, keyboard, monitor) / laptop with minimum specification: Intel Core Duo processor(1.66Hz), 1GB RAM, 60GB 5400 RPM HDD User Side Software Requirement: Web browser: Mozilla Firefox, IE, Google Chrome, etc Server Side Hardware Requirement: PC (with mouse, keyboard, monitor) / laptop with minimum specification: Intel Core Duo processor(1.66Hz), 1GB RAM, 60GB 5400 RPM HDD GSM Modem Server Side Software Requirement: Adobe Dreamweaver SQL Yog Web Browser: Mozilla Firefox, IE, Google Chrome, etc XAMPP Server side software requirement is needed to do the regular maintenance on the system. The development software might be needed to fix error that might be occurred when the system on the run. Chapter 2: Literature Review Literature Review Literature Review is a critical look at the existing research that is significant to the work that is currently undergo. The author currently did a project; College Announcement Notification System is the project. College Announcement Notification System is a web based application system, which is proposed as a solution to Sunway University College regarding the poor information flow in Sunway University College especially School of Computer Technology. The author chose to propose the solution only to School of Computer Technology because of the course that currently taken is under it. College Announcement Notification System is a web based application, it is hoped the system would work perfectly and increasing the information flow within School of Computer Technology (SCT). The users of the system able to access the College Announcement Notification System via laptop or PC, as long there is an internet connection. The author think if it just a normal website, there is no uniqueness that makes my project different than the others. After doing research, the author decided to add the SMS feature as the instant notification system. Integrate the system with SMS feature; means need to deal with SMS gateway. The author aware that using the SMS feature is almost the same like adding the Email as the instant notification where the system is able to send automatically the posted announcement that is already posted in the website. Email is an electronic mail that worked same like a normal mail, where the users need to write the content of the letter, after that the address of the recipient is a must for the users to add. Email enables users to send and receive electronically over the internet. SMS and Email basically is the same, it contains text and to send it need to know the exact recipient email address for email and phone number for SMS. There are many email server company that is give services for the users to send and receive email such as Hotmail, Yahoo Mail, Go ogle Mail, etc. There is also an application that handles email such as Microsoft Outlook. Some advantages that email could give are emails is free for users to use like send and receive mail, it can contains richer message contents than the conventional mail did. However from the advantages that an email, there are also a few disadvantages of emails. With the advancement of the technology nowadays, the previous email only can sent the words but nowadays, users can sent not only words but can attach richer media such as picture, video, file, etc. This advantages of email were misused by some people, it enable them to send virus, malicious software, spam that can harm the recipients PC or laptop. In order to overcome this security issue, the email provider companies try many ways to increase the security but the spammer can overcome the security and still sent the spam email that may contain virus and malicious software. Using the email as an instant notification to the College Announcement Notification System is a good choice but users may not open their own email daily, usually users open their email whenever the feel like to open it. Therefore, the author proposed to use the SMS system as the instant notification. There are few reasons that become the considerations of choosing SMS to be implemented. First reason, the project is a notification system so SMS is the best choice because after the sender sent it then the recipients received it in instant. Second reason, if using email the recipients of the email need to open their own laptop or PC, and then open the email service web page, it will takes time and not instant. Most of the students nowadays had their own mobile phone and they carry their mobile phone everywhere they go, so it is one of the reason why the author choose to use SMS as an instant notification. Mobile phone user aware that open a SMS is faster than open an Email. Nowadays, ma ny mobile phone producers now produced a new mobile phone that can handles in send or receive an email. However mobile phone that can handles send and receive email is still too expensive for the most of the mobile phone users only a few that can afford that. But if the SMS only, most of the mobile phone users able to send and receive that because it is the basic function that the mobile phone offer. SMS (Short Messaging Service) As most people known, SMS is a protocol used in communication that gives way to exchange of short message from one mobile phone to another mobile phone (tech-faq.com, 2009). Nowadays mobile phone takes an important part because it provides connections to the others that in the past impossible to do. The main usage of the mobile phone is to enable users to make a phone call wherever and whenever they are, beside used to call others; other main function of mobile phone that is growing rapidly is the usage of SMS service. SMS stands for Short Message Service. It is a technology that enables the sending and receiving of messages between mobile phones. SMS first appeared in Europe in 1992. It was included in the GSM (Global System for Mobile Communications) standards right at the beginning. Later it was ported to wireless technologies like CDMA and TDMA. The GSM and SMS standards were originally developed by 3GPP (Third Generation Partnership Project) is responsible for the development and maintenance of the GSM and SMS standards. As suggested by the name Short Message Service, the data that can be held by an SMS message is very limited. One SMS message can contain at most 140 bytes (1120 bits) of data, so one SMS message can contain up to: 160 characters if 7-bit character encoding is used. (7-bit character encoding is suitable for encoding Latin characters like English alphabets.) 70 characters if 16-bit Unicode UCS2 character encoding is used. (SMS text messages containing non-Latin characters like Chinese characters should use 16-bit character encoding.) SMS text messaging supports languages internationally. It works fine with all languages supported by Unicode, including Arabic, Chinese, Japanese and Korean. Besides text, SMS messages can also carry binary data. It is possible to send ringtones, pictures, operator logos, wallpapers, animations, business cards (e.g. VCards) and WAP configurations to a mobile phone with SMS messages. One major advantage of SMS is that it is supported by 100% GSM mobile phones. Almost all subscription plans provided by wireless carriers include inexpensive SMS messaging service. Unlike SMS, mobile technologies such as WAP and mobile Java are not supported on many old mobile phone models. (developershome.com, 2008) Usage of SMS As the mobile voice communication market approaches saturation, carriers are focusing on messaging as crucial value -added service to garner more mobile subscribers and generate greater market revenue. Specifically, SMS (Short Messaging Service) is emerging as one of the most important asynchronous communication that carriers provide. It is projected that in 2009 U.S subscribers will send over 126 billion messages via their mobile phone device, generating $8.6 billion revenues (Deng, Sun, Turner, Prince, 2008). Nowadays, people are presented with a wide variety of communication media such as email, instant messaging (IM), etc. To date, most researchers have focused on the use of SMS by teenager and young adult. Recently as SMS become the needs in our daily lives, older people also recognized the convenience of using SMS. It has been reported that over 74% of the mobile phone users worldwide is using SMS text messaging (Deng, Sun, Turner, Prince, 2008). How does the SMS works? Even if you are not talking on your cell phone, your phone is constantly sending and receiving information. It is talking to its cell phone tower over a pathway called acontrol channel. The reason for this chatter is so that the cell phone system knows which cell your phone is in, and so that your phone can change cells as you move around. Every so often, your phone and the tower will exchange a packetof data that lets both of them know that everything is OK. Your phone also uses the control channel for call setup. When someone tries to call you, the tower sends your phone a message over the control channel that tells your phone to play itsringtone. The tower also gives your phone a pair of voice channel frequencies to use for the call. The control channel also provides the pathway for SMS messages. When a friend sends you an SMS message, the message flows through the SMSC, then to the tower, and the tower sends the message to your phone as a little packet of data on the control channel. In the same way, when you send a message, your phone sends it to the tower on the control channel and it goes from the tower to the SMSC and from there to its destination. (howstuffworks.com, 2005) The SME (Short Message Entity), which is typically a mobile phone or a GSM modem, can be located in the fixed network or a mobile station, receives and sends short messages. The SME was sent to the SMSC.TheSMSC (Short Message Service Center)is the entity which does the job of store and forward of messages to and from the mobile station. After receiving the SME, then SMSC sent the SME to the SMS GMSC. TheSMS GMSC(SMS gateway MSC (Mobile Switching Center)) is a gateway so that MSC that can also receive short messages. The gateway MSC is a mobile networks point of contact with other networks. On receiving the short message from the short message center, GMSC uses the SS7 network to interrogate the current position of the mobile station form the HLR, the home location register. HLRis the main database in a mobile network. It holds information of the subscription profile of the mobile and also about the routing information for the subscriber, i.e. the area (covered by a MSC) where the mobile is currently situated. The GMSC is thus able to pass on the message to the correct MSC. MSC(Mobile Switching Center) is the entity in a GSM network which does the job of switching connections between mobile stations or between mobile stations and the fixed network. AVLR(Visitor Location Register) corresponds to each MSC and contains temporary information about the mobile, information like mobile identification and the cell (or a group of cells) where the mobile is currently situated. Using information from the VLR the MSC is able to switch the information (short message) to the corresponding BSS (Base Station System, BSC + BTSs), which transmits the short message to the mobile. The BSS consists of transceivers, which send and receive information over the air interface, to and from the mobile station. This information is passed over the signaling channels so the mobile can receive messages even if a voice or data call is going on. (logixmobile.com) How to send SMS using a computer? After done some research about how the SMS works, there are several ways in sending SMS using computer, they are (developershome.com, 2008): Connect a mobile phone or GSM/GPRS modem to a computer / PC. Then use the computer / PC and VB commands to instruct the mobile phone or GSM/GPRS modem to send SMS message. Connect the computer / PC to the SMS center (SMSC) or SMS gateway of a wireless carrier or SMS service provider. Then send SMS messages using a protocol / interface supported by the SMSC or SMS gateway. Connection between mobile phone or GSM/GPRS modem to computer using VB command for sent SMS A GSM/GPRS modem is a wireless modem that works with GSM/GPRS wireless networks. A wireless modem is similar to a dial-up modem. The main difference is that a wireless modem transmits data through a wireless network whereas a dial-up modem transmits data through a copper telephone line. To send SMS messages, first place a valid SIM card from a wireless carrier into a mobile phone or GSM/GPRS modem, which is then connected to a computer. There are several ways to connect a mobile phone or GSM/GPRS modem to a computer. For example, they can be connected through a serial cable, a USB cable, a Bluetooth link or an infrared link. The actual way to use depends on the capability of the mobile phone or GSM/GPRS modem. After connecting a mobile phone or GSM/GPRS modem to a computer, you can control the mobile phone or GSM/GPRS modem by sending instructions to it. The instructions used for controlling the mobile phone or GSM/GPRS modem are called by using VB commands. The above figure showed the process of sending SMS using the VB application. In this case, the system that the author developed is using PHP that act as the third party to store the announcement data inside the database. After finish with the stored announcement, VB application is used to instruct the GSM modem to send SMS. As shown in the figure above, VB application will retrieve the stored data that will be sent as SMS. Then after retrieving the data, it will be sent to through SMS gateway until it arrived in the hand of the recipient. One of the benefits from using the VB application to send SMS is users will have a very reliable notification system, because before sending SMS intended recipient can be configured so it is received at the intended recipient. Using a mobile phone or GSM/GPRS modem to send SMS messages has a major drawback, which is the SMS sending rate is too low. Only 6-10 SMS messages can be sent per minute (when the SMS over GSM mode is used). The performance is not affected by the connection between the computer and the mobile phone or GSM/GPRS modem (i.e. the SMS sending rate is about the same no matter the mobile phone or GSM/GPRS modem is connected to the computer through a serial cable, USB cable, Bluetooth link or infrared link) and does not depend on whether a mobile phone or GSM/GPRS modem is used (i.e. the SMS sending rate is about the same no matter a mobile phone or a GSM/GPRS modem is used). The determining factor for the SMS sending rate is the wireless network. (developershome.com, 2008) Send SMS from Computer through SMS Gateway The way for sending SMS messages from a computer through a mobile phone or GSM/GPRS modem has a major limitation, which is the SMS sending rate is too low. If you need a high SMS sending rate, obtaining a direct connection to the SMS center (SMSC) or SMS gateway of a wireless carrier is necessary. It can be difficult for small businesses or individual application developers to obtain a direct connection to the SMSC or SMS gateway of a wireless carrier since a wireless carrier may only provide such service to those who have huge SMS traffic. Buying SMS messages in bulk means the total fee will be very high (although the fee per SMS message will be low). (deve

Significance Of Site Layout Planning Construction Essay

Significance Of Site Layout Planning Construction Essay Site layout planning can affect productivity and is crucial to project success. However, as construction is heterogeneous in the nature of its organizations, project designs, time constraints, environmental effects, etc., site layout planning for each project becomes unique. Affected by many uncertainties variables! And variations, site layout planning is a typical multi objective problem. Introduction Problem solving requires representing the problem in a language that problem solvers can understand. However, solutions of most construction problems rely on empirical Knowledge about the site layout that can be as a site space allocation for material storage, working areas, units of accommodation, plant positions, general circulation areas, and also access and egress for deliveries and emergency services. Furthermore, conflicting objectives and the uniqueness of construction projects like bad site layout make the problems difficult to conceptualize and define. In this report presenting, a routine task for many site staff in both precontract and postcontract stages of site layout planning of the typical multi criteria and multi objective construction problems. It is very much influenced by types of construction, density of development, and whether the site is bad or in a good layout. Significance of Site Layout Planning Site layout shows the relationship of the proposed site with its surroundings with respect to communication, approaches, and existing facilities. Good site layout planning assists in minimizing the traveling time and movement costs of plant, labor, and materials, activity interference during construction work, and site accidents, and ensures that work on buildings and other construction positions is not impeded by the thoughtless storage of materials on these locations. So site layout can thus either enhance or adversely affect construction productivity and progress. It is important to acquire the knowledge of the project site before setting out the site layout. The knowledge about the project site can be obtained from: Site Investigation Site investigation is a process of site exploration consisting of boring, sampling and testing so as to obtain geotechnical information for a safe, practical and economical geotechnical evaluation and design. Generally it is an exploration or discovery of the ground conditions especially on untouched site. In other words the main purpose of site investigation is to determine within practical limits, the depth, thickness, extent and compositions of each subsoil stratum, the depth and type of rock, the depth and composition of groundwater, the strength, compressibility and hydraulic characteristics of soil strata required by geotechnical engineers. Sometimes it is also known as geotechnical investigation. Wok Procedure for SI Steps of work involved in site investigation: 1.Desk study to collect all the relevant data and information, 2.Reconnaissance of site works, 3.Planning program after reviewing the above, 4.Ground or soil exploration includes boring, sampling and testing, 5.Laboratory testing (also field if necessary), 6.Preparation and documentation of SI report, 7.Engineering design stages, 8.Review during construction and monitoring. Steps of Soil Exploration Soil exploration consists of: Boring: Refers to drilling or advancing a hole in the ground. The test would include hand auger, motorized hand boring (wash boring), deep boring (rotary drilling), and/or trial pits. Sampling: Refers to removing soil from the hole. The samples can be classified as disturbed or undisturbed sampling. Disturbed samples are usually used for soil grain-size analysis, determination of liquid limit, specific gravity of soil as well as compaction test and California bearing ratio (CBR). The undisturbed samples are collected at least every 1.5 m and if changes occur within 1.5 m intervals, an additional sample should be taken. Testing: Refers to determining the properties from the soil. The test can be performing either at laboratory or at field. Laboratory testing would normally be moisture content, sieve analysis, liquid limit, compaction test, CBR and so forth. Field test would include Standard Penetration Test (SPT), Cone Penetration Test (CPT) and Vane test. Record of Soil Exploration It is important to keep complete and accurate records of all data collected. Boring, sampling and testing are often costly. A good map giving specific locations of all boring should be available. All boring should be identified and its location documented by measurement to permanent features. And all pertinent data should be recorded in the field on a boring log sheet. Soil data obtained from a series of test boring can best be presented by preparing a geologic profile: Arrangement of various layers of soil, Ground water table, Existing / proposed structures, Soil properties data (e.g., Standard Penetration Test values). The profile was prepared with data obtained from the boring, sampling and testing of each borehole from selected points. Summarizing Scope of site investigation works when planned by different engineers tend to be varied because there are an infinite number of conditions to be met and the process of planning also leaves many areas where individual judgment and experiences must be applied. It is also impossible to attempt to provide an exhaustive step by step guideline applicable to all possible cases. It should be realized that there is a possibility that any site investigation may leave some area unexplored or overlooked. The main risk in foundation design is the uncertainty involving in predicting soil conditions which may change with environment. The more site investigation the more it will reduce the margin of uncertainty but the time and cost requirement will be exorbitant. Therefore the extent and the cost of Site Investigation should be such that risk is at an established acceptable level to the designer and also comply to the accepted code of practice. Decision Criteria and Site Facilities Adopted in Site Layout Planning Although each site layout is unique, site layout planning can be resolved into a repetitive selection-evaluation process. Several analysis techniques can be used for the selection process for example, the dominant factor analysis and Parker s judgment technique, which can be used to screen out available decisions in choosing facilities, and identify key decision factors and locations for each particular facility. All space-planning problems consist of a set of activities to be located and a space in which to locate them. Site layout planning consists of identifying the facilities needed to support construction operations, determining their size and shape, and positioning them within the boundaries of the site. So, the most temporary facilities are classified into six important categories, which are tabulated in Table 1. Table1. General Classification of Temporary Facilities Temporary facilities Description Access road and exit Needs vary with the type of project and the stage of the job. It will normally be linked with the plan of construction and in some cases may actually control the progress of construction. Ideally, short direct routes and one-way traffic are encouraged. Location of plant and equipment Choice of the major items of the plant is of real consequence on most sites. Correctly chosen and well operated and maintained equipment enables a construction project to be completed efficiently and economically. Material storage and handling area Areas must be set aside for the storage and handling of material. The objective here is to minimize waste and losses arising from careless handling, bad storage, or theft, and to reduce costs by obviating double handling or unnecessary movement. Site accommodations and welfare facilities Consideration should always be given to the possibility of ensuring that the site accommodations are kept at a suitable distance from the construction work and are in such a position to enable the site staff to conduct their duties (welfare facilities also) Temporary services This includes water supply, electricity supply, gas, telephones, and drainage the requirements of which may vary between different projects. Workshop position Position should be indicated to enable the site supervisor to arrange for the erection of the following types of workshops: 1) fitter s shops and work area; 2) joinery shop and machinery area; 3) Reinforcement and bar bending areas; and 4) Concrete mixing. Bad site layout planning Bad site layout is usually a multi criteria problem involving in construction site without any or less temporary facilities regarding to the type of project. Fig1.Bad site layout Figure1 shows one of the bad site layouts occurs daily in construction site that the Decision makers made mistake. As you can see there are some missing temporary facilities like: 1. There is no enough access road to use. Only have two main entries that all type of vehicles can access. 2. No female toilet for any side of the site layout. 3. They don t provide any temporary office place 4. There is no storage for steel, timber and other facilities. 5. No temporary services including water supply pipes and waste storage like septic tank. According to all that things, we can say the site layout planning is bad layout. Cause for the lake of or missing of some important facilities that leads the hall project to be fulfilled. Conclusion Site investigation product plane such as space allocations and material transportations need a lot of experience and knowledge. The planning of a site layout in practice will depend upon a number of factors such as the time and money. The need for careful site layout and site organization planning becomes more relevant as the size and complexity of the construction operation increases, and especially where spare site space is very limited.

Essay --

The widespread violence in the Democratic Republic of the Congo (DRC) is associated with an epidemic of rape. The alarming brutality in the Eastern Congo results in thousands of cases of rape and genital injury with devastating psychosocial consequences. A disturbing ideology promoting and rewarding behavioral dominance through the subjugation and violent treatment of men, women, and children, led to an emerging socially literate psychology of militarized masculinity. Through active examinations of this framework, concepts like rape as a weapon of war emerge in an attempt to explain the connection between the proliferation of armed groups and the perpetration of sexual violence as a pervasive and destructive feature of society. In this conflict environment, rape is a vehicle for terrorism, displacement, and demoralization that deliberately incurs severe sexual trauma leading to a new pathology of rape with extreme violence . These emerging pathologies are denoted as social phenomena , emerging in the context of war from perpetuated violence, and explained in retrospective analyses of sexual violence. We view the role of social behavior through the interactions between aggregated individual acts of rape, and the long-standing systematic pressures and processes in the conflict. What’s missing is the analysis of collective behavior and the impacts on social cohesion. In the Congo, wider social norms and entities – the masculine collective – like rebel groups continue to promote behavior conducive to sexual violence. It is therefore important to go beyond the traditionally narrow individualism of gender analysis, and examine the behavioral products of masculine socialization – moving the conversation from morality to sociology, and f... ...ctural violence that makes them a target of sexual violence. This cover-up is done through established sociospatial zones that engender violence and characterize the environment as a space in which violence routinely occurs, and where women are routinely violated. Most examinations in the Congo focus on the practical military application of rape as a weapon, not the psychosocial implications that enable intimate partners to take advantage of men, women, and children. Because intimate partners are presumed to be far removed from a military context, and are viewed as civilians, they are effectively removed from the zone of scrutiny and find solace in sociospatial zones which condone sexual violence. As a result, the victims are ultimately blamed for the violence visited upon them, and the enormity of what is done to them in these areas remains largely unacknowledged.

A funeral in my Brain Essay -- essays research papers

I Felt a Funeral in My Brian â€Å"I felt a funeral in my brain† by Emily Dickinson traces the speaker’s descent into madness. It is a terrifying poem for both the speaker and the reader. The speaker experiences the loss of self in the chaos of the unconscious, and the reader experiences the speaker’s descending madness and the horror most of us feel about going crazy. Dickinson uses the metaphor of a funeral to represent the speaker’s sense that a part of her is dying. This is reason for her, being overwhelmed by the irrationality of the unconscious. A funeral is an appropriate image for this ordeal. The most obvious connotation with a funeral is death. Also a funeral is a formal event, whose rules and procedures suggest control and order. The control and order implicit in a funeral contras...

Values-Based Leadership Essay -- Transformational Leaders

Leadership Background Values-based leadership has a significant impact on the performance and the functioning of an organization. Boje,(2000) cites Burn’s (1978) theoretical work on transformational leadership basing his argument on Kohlberg’s moral development theory and Weber’s (1947) theory of leadership and authority. In his work, Boje, 2000 agrees with Burn’s that a moral value based leader, is the one who emphasizes social exchange between leader and follower in the form of the psychological and mutual needs contract driven by charisma, individualized consideration, intellectual stimulation and inspirational motivation.(Homrig, 2001) The transcendent values of transformational leaders have great potential to promote performance beyond expectations and to effect enormous change on how the organization operates since they seek liberty, justice, equality and collective well being. It therefore appears that a transformational leadership is that kind of leadership that seeks to exploit the full potential of individuals through satisfaction of collective needs. While Weber’s theory (1947) is cited by Boje, (2000) as having several forms of leadership like charismatic, bureaucratic and traditional aspects, all co-exist together and change from the other occurs gradually. Even though the two theorists; Weber (1947) and Burn’s (1978) approaches leadership from different perspectives, Boje acknowledges that both of them share a similarity in their work in the sense that both see moral values as an important consideration in any form of leadership.( Boje, 2000). Transformational leaders inspire followers to achieve extraordinary outcomes by providing both meaning and understanding, questioning assumptions, refraining problems, and... ...e vision and mission of the company in order to align their goals with of the company. When Robert Eaton became the chairman in 1993 he involved company officers to develop the vision and the mission. Consequently, better communications, continuous training became part and puzzle of doing business in a new way. (Ashley, 1997) In conclusion, leadership is not only important to companies that operate on a global scale but to domestic firms as well. It’s clear that when a leader takes his or her rightful position as a leader change, performance and results manifest. Their values and beliefs become the guiding principles where ideas, imaginations and talents are shared by all. Such transformational leaders not only make their employees to follow them, but they help one another to grow, motivate raise the morale of achieving extraordinary outcomes with few resources.

International Economy (Eu)& UK Construction Sector Essay

When John Maynard Keynes, father of modern microeconomics, first formulated the theory of how to increase national product, brass domestic production, and address the issues of inflation and unemployment, government spending was the example that he drew upon as one of the economic solutions in order to escape such problems which had significantly impacted the United States in many European countries and even resulted in the economic Great Depression. This is important especially for the topic of construction and infrastructure in the United Kingdom because, as the economist had place it, construction and infrastructure projects are the largest government spending economic activities (Begg et al. 2008). Therefore, in the question of economic development for the UK, construction in such public Works by the government is seen as the primary way in order to follow such economic concepts to avoid further microeconomic problems. However, economics understands that the local projects such as infrastructure that are created by the government in order to deliver services under the umbrella of public goods do not occur in a static situation and there are other external economic variables that are taken into consideration in such an occurrence(Begg et al. 2008). Therefore, especially in today’s global economy, the international economy plays an important role in the construction sector of the United Kingdom and that specific industry. The area of financing or one of the international economic factors that play a significant role. Remember that government infrastructure and public works projects are often extremely expensive public good initiatives that could not be handled and funded by local governments in that process. In the example of Third World countries, most development and infrastructure projects are gone about by borrowing in international institutions such as the World Bank and international monetary fund. In the United Kingdom, however, a first world country, even though they’re also funds allocated by the local government for such infrastructure projects, international financing through economic cooperation activities with other countries place the role of funding such government works (Obstfeld et al. 2005). The macro economic multiplier effect for labor and consumption claims that such funds that are borrowed from international economies may be repaid by the exponential growth in reduction in a country which is created by labor growth in labor consumption through production. Another importance of the international community to local construction projects is that construction and engineering eventually creates knowledge spillovers especially for countries that have made use of   the same kinds of infrastructure. Such knowledge spillovers are important especially in the generation of higher-level management and individuals who have knowledge — and eventually economies of scale — in such construction and infrastructure projects. Without previous knowledge, or costly for the United Kingdom to implement construction projects on its own especially for the relevant on the risk public works infrastructure (Caves 2007). In this respect, the European Union, the larger economic umbrella in the area, is able to address both these issues especially the first one. In international trade theory in economics, there are five levels of economic operations, where a trade union is the highest one that generates international capital mobility as well as international labor mobility among members of such trade union and economic cooperation (Artis & Nixson 2007). Therefore, the existence of European Union significantly contributes to improvements in the public works infrastructure sector of the United Kingdom.
