Public Sector & Government Budgeting - Capital Improvement Plan (CIP) Assignment

Public Sector & Government Budgeting - Capital Improvement Plan (CIP) - Assignment Example oosing projects, and in this instance, the LBRA involvement is vital to resolve the agony of blight and the blighting effect to the community around in the region. The third top factor that have been raised is selecting and giving first priority to those ventures that people are willing and ready to shore up to their accomplishment (Launar & Nollar, 2005). It is obvious that all the shareholders and the members in any company or an institution will always have the desire and the longing to see best improvement, from the effort they put in that company, cooperation or an institution. Therefore, the redevelopment and structuring projects are done in the accurate time. The arrangement, endorsement and planning of these projects are also done within the stipulated time in line with their accomplishment and the desire of the stake holders (Bland 2007). In the capital improvement policy statement, there are issues like appropriate management of resources and funds. Timely accomplishment of projects is also taken with greater weight in the policy. These issues are well addressed in the long beach city of California since most of the projects had been accomplished on time. The preparation of operating budget ought to be separated from the capital budget, to prevent the mismanagement of funds and resources. This may also be done to avoid interfering with each other final records. Finally, the separation may be done so as to have different independent projects that at the end will yield best

Aristotle on the weakness of the will Essay Example | Topics and Well Written Essays - 750 words

Aristotle on the weakness of the will - Essay Example However, the theory of Aristotle is more profound. He does not agree with Plato and Socrates in their views on the weaknesses of the will. In contrast to Socrates, Aristotle does not think that people will act in the right way in case they know what is good and what is bad. He also does not agree with Plato, who states that in order to follow ethical principles, people should receive corresponding education. Aristotle is sure that every person may understand what is good and what is bad in everyday behavior not depending on his/her education or position. However, not every person chooses to follow the principles even if he/she understands and knows them. Speaking about the weaknesses of the will we should mention akrasia, a state that makes people act in the wrong way. Every philosopher understands it differently. According to Socrates, akrasia prevents people from proper self-development. For him akrasia is something illogical as he states in Protagoras â€Å"No one goes willingly toward the bad (Protagoras 358d)†. Socrates is sure that if a person analyses the situation and decides the best way to act, he/ she will definitely follow this way. Thus, Socrates denies the possibility of illogical action (akrasia). In Protagoras Plato also denies akrasia, but in later works he acknowledges its possibility. He analyses a soul in state of akrasia and comes to the conclusion that if people decides that to act akratically is the best way for them, they will act akratically. It does not mean that a person who acts akratically has no virtues, but when he/she acts akratically, at least one of the virtues is lost. In contrast to Socrates, Aristotle acknowledges the state of akrasia and in contrast to Plato, he considers akrasia to be the one of the states that should be avoided. He associates the state of akrasia with the state of weakness, when a person knows that he acts in a bad way, but he/she is too weak to act differently. According to Socrates, people do wro ng when they lack some knowledge. The philosopher states that people can become wiser. Those people, who do not think that they know everything, continue self-development and become wiser: "I know that I know nothing  noble and good" (Apology 21d). Those who think that they know everything, do not develop further and do not become wiser, thus they can do wrong. Aristotle agrees with Socrates that wrongdoing may be a consequence of ignorance. But, according to Aristotle, ignorance may serve as an excuse only in some cases (Nicomachean Ethics, Book VII). The strength of Aristotle’s view is in his understanding that people do not always act in the right way even if they know that they do wrong. Socrates values virtues very high and is sure that knowledge is the main source of virtue, and those who possess knowledge will not act irrationally or akratically. This is the weakness of the philosophy of Socrates. The weakness of the philosophy of Plato is that he states that people should receive education in order to follow ethical principles. Aristotle is right assuming that even those who possess knowledge can do wrong. He states that virtue does not depend on corresponding education and it is not necessary to be educated in order to possess virtues. Every person should know how to behave in everyday life and most of the people possess corresponding virtues, but not all the people act in accordance with the virtues they possess. Sometimes when deciding how to act people act in the way that would benefit them most. In this case the virtue can be ignored deliberately. Such situation is frequently met in our life. Another case, when people may act in the wrong way, is the case of ignoring virtues, because of the lack of knowledge how to apply it. It is not

Othellos position as an outsider fuelled by his insecurities Essay Example for Free

Othellos position as an outsider fuelled by his insecurities Essay In what ways does Othellos position as an outsider fuelled by his insecurities bring about his downfall? Shakespeare was on of the greatest writer of all time he wrote many plays and among them there are his timeless tragedies. Some of the most popular are Romeo and Juliet, a typical love tragedy, Macbeth and the famous Othello. Tragedy is one of the oldest genres in literature. It started off in Greek times and one of the earliest writers was Aristotle. Shakespeare was influenced by Greek and Roman thought and ideas, which he used in his own revenge tragedies. Shakespearean tragedies are all set around the hero. The hero normally has a fatal flaw that causes the downfall of the hero. These ideas are clearly shown in the revenge tragedy Othello. In the play, Othello is a typical revenge hero. Othello is a cultural and racial outsider he is a moor, which is a natural of Northern Africa. This featured separates him from the other characters. He is a well-respected man who is a loyal officer and has repeatedly proved himself in a battle, but people still do not accept him as one of them. This fuels Othellos insecurities and the way people treat and talk to him build on the many insecurities he already has. Throughout the play there are many references to Othellos race and social background. In scene one the audience are introduced to Othello through Iago and Brabantio conversing about him. The audience are informed that he is marrying the Kings daughter (Desdemona) behind the Kings back. This is highlighted by a quote from Act one Scene one A black ram is tupping your white +ewe. The audiences first impressions of Othello are that he is sly and untrustworthy. The imagery used by Iago black ram and white yew signifies the differences between Desdemona and Othello, Othello is black and Desdemona is white. Not simply this but other ideas are connoted by these images to the audience. Black symbolising hate and evil while white symbolising purity, good and angelic. This opposite effect between them gives a negative effect on the audience about Othello. Witchcraft is spoken of He thought twas witchcraft by Iago and Rodrigo as there is no other reason for a pure and angelic character to love such a hideous beast. The ideas of witchcraft being mentioned shows that people are thinking that Othello has put a spell on Desdemona for her to love him. Othello isnt seen as attractive or conventionally good looking. His colour makes him unappealing and frightening implied by the imagery used by people in the play when speaking about Othello. When referring to Othello. The Moor and Thick lips are used as references to Othellos colour in many scenes. The imagery of animals or beasts is used a lot, Black ram and barbary horse. This is bringing Othello to an animalistic level with the imagery of wild un tamed animals or beasts. This is used to insult Othellos colour and his racial background. By saying he is of a low level and uncivilised. Although a lot of insults are directed towards Othello these insults are never spoken to his face. This is because Othello is a valuable and skilled soldier he has done a lot for the country and people respect him for that. I have done the state some service and they knowt. When speaking to Othello, Iago and Rodrigo call him my lord This shows respect and Othello seems to be accepted into their Venetian society because of his fighting ability, although the dramatic irony is clearly shown when Iago says, I do hate him as I do hells pains but when speaking to Othello in Act 4 Scene 4 he says. You know I love you my lord. This would be one thing that would change the audiences views about Othello and make them more aware of Iago as this starts to show his true colours. Iago mentions the word hell signifying the devil and pure evil, this again relates to the views and opinions people have on Othellos racial background. His black skin reinforces the images and thoughts also. Discrimination is a key theme during this play a lot of which is aimed at Othello. Although Othello has been accepted into their society he still feels conscious about his racial background as he states , haply, for I am black. Othello knows that hes an outsider to them and understands why, his unknown qualities may be threat to some but on the other hand others are intrigued which Is shown when he says, her father loved me/oft invited me/still questioned me about the story of my life. People do not like to accept the unknown but like to question it or like Iago feel the need to push it away. The unknown is ventured into by Desdemona she crosses the line between her society and the unknown by marrying Othello. This shocks and seems outrageous but it helps Othello be accepted more into their society. Desdemona was once too scared by Othellos race this is highlighted by the quote And when she seemed to shake and fear your looks. But she looked beyond this I saw Othellos visage in his mind. This shows that if one can see the inner beauty then why cant every one else? Perception is a key theme during the play. The audience see that Othello is beautiful not on the outside but on the inside. Iago although he appears beautiful the audience see a different view they see more than skin deep. Desdemona accepts Othello for who he is, therefore Othello feels safe and secure with her. He loves and adores Desdemona and would do anything for her. This is clearly shown in Act4 Scene4 And I when I love thee not, chaos is come again. This is implying that without Desdemonas love it would be the end of the world, the end of Othello. When Iago starts to question Desdemonas love for Othello, Othello now feels he cannot trust Desdemona. This affects him because she makes him feel accepted because she loves him for who he is and now he feels unaccepted into their society. Iago knows this so he plays on these insecurities to get what he wants. I think this quote is a good description telling the audience he is comparing Othello to an Ass, and Iago is leading him with his lies. And will as tenderly be led by thnose as asses are. This creates an image of an animal being led away so easily by something so simple, but by something it loves and craves. Iago does not tell Othello anything about Desdemona and Cassio he just cleverly puts thoughts into Othellos head, it is shown well n this quote, Ha I like not thatNothing my lord. Iago immediately catches Othellos attention and he is eager to find out more. Iago plants the seed of doubt and nurtures it over act 3. Iago carries on and starts to mention Cassio although he doesnt say anything about Desdemona and Cassio being together he implies it, shown in this quote I cannot think he would sneak away so guilty like, seeing you coming. These quick sentences get Othellos mind racing, with doubt and jealousy. The words that make Othello eager are sneak and guilty this really sets the scene for a private affair. Othello panics and he answers Iago quick trying to find out more. What dost though think? As the scene progresses Othello becomes suspicious and starts to get annoyed with Iago, as it seems Iago knows something and is not telling Othello, Othello says Show me thy thought. Othello, feeling an outsider already is now separated from the group even more as there are secrets revolving around that he knows nothing of. Iago realises that Othello may not believe him, to get Othello to trust him and start to believe him he says You know I love you my lord. This dramatic Irony starts to show the audience that the real villain is Iago in the play and their sympathy goes out to Othello as all he is, is another cog in Iagos conniving and twisted plan. Toward the end of the scene Iago starts to really play on the insecurities of Othello. She did deceive her father marrying you. This implies that if she can deceive her own blood then what chance does Othello have? This idea was brought up at the start of the play when Othello was speaking to Desdemonas father, and he warns Othello of her background telling him that she has deceived him many times before. So Othello starts to really believe it now. Why did I marry? To make sure Othello really understands Iago, Iago starts to imply that Othello being an outsider means he does not know a lot about their society. Iago comes from this society so anything said, Othello will believe because he doesnt know any different. In Venice they do not let god see their pranks, they dare not show their husbands; their best conscious. Here Iago is implying that Venetian women are not what they seem. Iago knows this from past experience and implies Othello has been pulled in by their deceptive ways. Othello is starting to doubt his position in the society as he realises he does not know enough. This plays on his insecurities and he feels more of an outsider than hes ever felt. This is shown by his epileptic fits on stage as he works himself up so much his body shuts itself down. His epileptic fits contribute to his outsider qualities as this is a fault within him, which separates him from the society. People dont understand him and therefore cant accept him totally into their society. This gives Iago a chance to work situations to his advantage like the Cassio and Bianca scene. Othello becomes more and more insecure and vulnerable he needs to rely on Iagos advises more. Iago gets him to depend on him and a power change occurs. The audience are aware of the change by Act 4 scene 4 when it is clearly shown. From then on Othello becomes more and more insecure, and Iago feeds on his weakness. Rude am I in speech / And little blessed with the soft phrase of peace. (A statement form Othello.) This is showing us that Othello is presenting himself as an outsider and constantly brings up his differences from other Venetians. This insecurity is brought on by the thoughts of other people. If everyone else thinks it, then Othello starts to think it too because he is so unsure about himself. Another quote that shows this is when Othello says, Haply for I am black/and have not those soft parts of conversation. Othello knows he is discriminated against his colour and he admits it Haply for I am black, his colour is linked to the ideas of a beast he refers to this by saying, have not those soft parts. The soft in this sentence is the total opposite of what is thought about Othello. He now discriminated himself and compares him self to other people and this is when he thinks his whole world is crumbling around him especially because his one true love has supposedly betrayed him. If Othello chooses not to believe in himself and lets himself be an outsider from the rest, then what chance does he have expecting others to accept him? Othellos position as an outsider is in a lot of way fuelled by his insecurities. This is a serious weakness that comes across on Othello and the paranoia he has upon himself does not help. Desdemona gave him the confidence to not care, but Iagos twisted and conniving ways led Othello to believe his one true love was not there beside him any more helping him through the tough times. Desdemona fuelled the little confidence Othello had and it was this reason that Iago used to break Othello. In the last scene Othello speaks Like a base Indian, threw a pearl away. Here in this metaphor Othello has realised Desdemona was his pearl the one thing left that made him she was his world and his world had now gone.

The Process Of Time Table Construction Computer Science Essay

The Process Of Time Table Construction Computer Science Essay The process of time-table construction can prove to be a hectic task considering the number of cohorts [courses] and the modules [subjects] offered by a specific university. This is mainly because, there could be a deadlock in allotment of the schedule considering all the constraints to be satisfied .This requires logical thinking which definitely consumes a large amount of time. Moreover, identification of the inconsistencies and their respective solutions can prove to be disastrous. Initially , the task of time table scheduling was done manually .This proved to be troublesome ,error-prone and time consuming .To overcome these problems , automated exam time-table generation has come to light. With a wider range of choices available to the students in the selection of modules [ subjects ] and cohorts [ courses] of their choice , the flexibility of the University improves but at the same time , the task of time-table creation becomes merely complicated .However , a software which can consider all the constraints and cross faculty modules [latter includes the modules taken by students from various faculties]as well , is of immense help. Thus ,the scientific society has given considerable attention to automated time-table generation from the last four decades .One of the most primitive ones used the concepts of one or more of the following operational methodologies network flow techniques reduction to graph coloring integer programming direct heuristics and more The latest technology uses advanced techniques like expert systems which work on the concept of artificial intelligence, logic programming which uses languages like Prolog, constraint logic programming and generic evolutionary algorithms .However , there is no universally accepted language for time-table creation. Several attempts have been made to formulate one but these are left incomplete. In this software , the constraint satisfaction is 99% .Moreover , the interface developed is use friendly where in the user doesnt have to enter the names of the cohorts and modules which he wishes to opt for as he can just select the same from the drop down lists . WHAT IS CONSTRAINT SATISFACTION? Constraint satisfaction was first introduced in artificial intelligence .This is a logical problem solving language merged with a programming language which is used to solve a given problem with a specific set of constraints. This deals with the assignment of certain values to the variables while meeting certain conditions. It is represented as a set of variables Xi and a set of constraints Ci where each constraint specifies a subset of variables and an allowable combination of these. In this project some of the main constraints which are to be considered are as below: Students belonging to different cohorts but studying a common module must have the exam on the same day. No two modules of the same cohorts can have their respective exams on the same day One of the soft constraints is that no two exams of the same cohort must be on the same day Thus, these are satisfied before the software is deployed .The techniques used in constraint satisfaction are purely dependent on the constraints. Constraints specific to a finite domain are solved using search strategies in the form of backtracking or local search. Constraint propagation is yet another technique which is used but however is sometimes incomplete. That is it either solves the problem or proves and declares it unsatisfiable .These methods are combined with the search strategies to simplify the process. There are many constraint programming libraries which can be included in this project. Since Java is the platform we develop the project on, Choco is an appropriate library which can be easily used with Java programming .it is an event based propagating system with backtrack structures. More on Choco is discussed in the later sections on the report. BRUTE FORCE TECHNIQUE: Brute force technique is a process of finding the result by taking all the possible inputs i.e., a trial and error process. If a taken Input yields the correct result then it is treated as the correct input. If not then it goes for the next input until we get the correct result. We can consider knapsack problem as an example of a brute force technique. Knapsack problem generally means a bag which should be filled with weights that should yield maximum profit. The most implicit constraint of knapsack problem is to maximize profit with minimum weight. Let us say there a four types of materials as follows gold , silver , platinum and bronze with profit values of 1000,10,2000 and 5 and weights of 2,3,4,5 .Thief want more profit with his minimum capacity bag let us say it can fit 5.So he applies the brute force technique to get maximum profit.First he fills the bag with gold which weights 2 and then goes for silver which weights 3 here the bag is full and yielding the profit of 1000+10=1010. Now he tries of another combination i.e., he selects platinum which weights 4 and now the rest of the bag is only one so he can select the  ½ part of gold which weights 1 thus the bag is filled with yielding 2000+500=2500 .In this manner different combinations are tried until the max profit is yielded. CHAPTER 2 Aims and Objectives The manual process of generating exam timetable by taking all constraints into consideration is very much time taking and difficult process. So the main aim of this project is to build a software tool to create exam timetables for a university or a school and the application should be user friendly and should satisfy all the constraints. The brief explanation of this is as follows: First analyze the manual process in developing exam time table that is following in schools and universities. This analysis helps us in developing the software tool. After analyzing the manual process we should make a list of all possible constraints which should be satisfied by the developed system. We should identify all the constraints that should be satisfied by our developed system and we should analyze them which is helpful in developing the software product. To gain an understanding of constraint satisfaction tool like choco which we are using in the development process. The developed product should be user friendly, so that user can use the system easily. In AUTOMATED EXAM TIME TABLE product the user should input the cohort name and module name. Instead of typing the entire cohort and module name we should put a dropdown list where user selects from it. By this we can eliminate the incorrect typing. The developed product should satisfy constraints like two exams of the same year of both semesters should not be on the same day. Every student should get their exams on alternate days only. All such type of major constraints should be satisfied by our product. MOTIVATION: Most of the people are interested in playing chess. By playing chess we can improve our concentration power. We have an idea of creating code for playing chess. As chess is played by two players one player is automated and another player plays manually. Here constraint satisfaction is used because there are certain conditions like elephant should have only straight moves, soldier should have one step straight move etc., we have to design our code by satisfying these conditions. Our program is used by the player in the absence of his partner. This player makes use of graphical user interface to opt his plots against other player which makes use of our code. So here artificial intelligence is used. This idea motivated us for designing automated examination time tabling software. FEATURES: Exams are scheduled such that no two exams are overlapped for the same student. Students are informed in case of any changes in the examination schedule like postponement, or preponement etc. User can save data so that he can view the application if he reopens it again. Students are allotted examination halls in a proper way so that a single student is not allotted in two different rooms. Proper allotment of staff in examination halls. Student can post his problems regarding exams. User can add modules to this software if they are relevant to this software. KEY TECHNIQUES JAVA PROGRAMMING JAVA is the language which has many features like multithreading, platform dependent, simple, robust, object oriented etc. Java is portable and performance levels of it are too high. Java concepts are very simple and understandable. Exceptions are also perfectly managed by Java. Database connectivity, GUI, IO packages is the main concepts due to which we go for java programming. CONSTRAINT SATISFACTION PROGRAMMING USING CHOCO CHOCO is a java library which is mainly used for constraint satisfaction. CHOCO is based on events which have the capability of backtracking. It can be used for many purposes like teaching, researching etc. So by using this constraint satisfaction programming we can develop the exam time table perfectly. ORACLE DATABASE FOR DATA STORAGE AND RETRIEVAL Database is a collection of entities. Data is a collection of similar raw information. Data is represented with the help of views or tables. View is not a physical entity. It is the representation for shadow of tables. Oracle database is mainly used for data storage and retrieval. That is data is stored in a place and in future if we want that data we can easily retrieve it. For developing the exam timetable in a university the above three key techniques are very very important and by using these techniques only the development processing of timetable can be done perfectly. SYSTEM REQUIREMENTS There are two types of system requirements software and hardware. SOFTWARE REQUIREMENTS Based on the operating system many things may depend. So selection of operating system plays very important role. WINDOWS XP operating system is the most appropriate operating system for software requirements of developing exam timetable. Oracle 10g relational database management system is also one of the software requirements. For developing the JAVA code My Eclipse Tool is the most suitable software requirement. For constraint satisfaction programming the preferred version is CHOCO 2.1.0. These are the minimum and most important software requirements for developing exam time table. HARDWARE REQUIREMENTS The processor required is Pentium 111 processor with 800MHz. Oracle database 10g and Java code developing tool must be on run mode at the same time so 1GB RAM is required. 20GB HDD also required as hardware requirement. These are the minimum and most important hardware requirements for developing exam time table. CHAPTER 3 SYSTEM ANALYSIS Existing System: The timetable management of a university was initially done normally by using some primitive methods and algorithms. The planning is made by a group of people and the timetable is fixed after certain negotiations. The university needs to set the timetable for each and every student separately and then finalize the whole timetable. The Timetable that is prepared by the Examination department of that institution needs to be sent in atleast 45 days advance to all the departments of the university and concerned affiliated colleges also. There are some issues regarding the timetable preparation. They are The students belonging to different departments will have the subjects related to their course. The subjects may be in common for certain branches. So the timetable designer needs to have a proper idea regarding the date and time of the examinations making sure that the same subject to different departments is conducted on the same day and at the same time. This reduces the extra effort for preparing different sets of question papers and ensuring the same complexity of the paper. A subject may be completed in advance by certain departments and there might be certain students who had failed that certain subject. The students who have failed in the regular examinations are given a chance for writing the supplementary examinations in the next semester. There is a chance of anomaly that the regular examination of the current semester and the supplementary examination for the previous semester may fall on the same day and same time. So the timetable adjustment must be flexible in such a way that no student misses any of the examinations. The regular student needs to have at least a day gap in between the examinations so that he can get ample amount of time for preparation for the next examination. The availability of the invigilators also needs to be checked before scheduling a particular examination. The staff members who are not assigned any class work at that time are to be taken and the schedule for a particular staff is to be prepared. The subject that is opted by maximum number of students is to be held as the first examination itself. The reason behind this is that, if the subject that is opted by maximum number of students is conducted at the last then there would be a problem in validating the answer scripts. So overcoming all the above mentioned issues is a hectic task. The timetable designer needs to have an idea regarding all those issues. The time taken by an individual to overcome all the above issues may take a few months of time. Proposed System: The proposed system of timetable management is rather a key solution for all the above mentioned issues. It gains its importance in eliminating the potential risks that are involved in the process. We can give certain number of constraints as the input and the schedule is prepared considering the constraints. The software is flexible enough for the users to enter the starting and the ending date of the examinations, the names of the students and their respective departments are present in the database and the details are retrieved accordingly. The result of the examination is automatically stored in the database for the preparation of the next semesters timetable. The proposed system is considerably quicker and more efficient. CHAPTER 4 SOFTWARE TOOLS DISCUSSION 1.CONSTRAINT SATISFACTION: We have a lot of constraints which need to be imposed and satisfied in our project. Basically CONSTRAINT SATISFACTION can be defined as the process of finding a solution to a set of constraints that impose conditions for which the variables must satisfy. In general terms, a solution is the set of variables that satisfies all the constraints.This can also be defined as the outcome of constraint satisfaction 2. CONSTRAINT SATISFACTION PROBLEM(CSP): A CONSTRAINT SATISFACTION PROBLEM(CSP) is defined by a set of variables each having a specific domain and also a set of constraints each involving a set of variables. These constraints restrict the values that the variables can take. A CSP performs these two tasks simultaneously. Now coming to the solution to CSP, it is just an assignment that maps every defined variable to a value. There may be cases where you may want to find just one solution, all possible solutions or an optimal solution based on the given objective function in terms of variables. A general constraint problem consists of the following: A set of variables A={a1,a2,à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦.an} For each variable ai, a finite domain set Di of its possible values. D={D(a1),D(a2),à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦.D(an)}. A set of constraints to restrict the values that the variables can take. C={C1,C2,à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Cj}. 3. CONSTRAINTS SOLVER: Now we need a constraint satisfaction tool to solve the considered constraints. This tool can be combined with any other programming languages like C,C++,JAVA etc. This tool is nothing but the constraint satisfaction libraries . As we move on with the java programming in our project, different constraint satisfaction java libraries available are given below: Choco JaCop Qstudio Avaya Aptana JCL Koalog From above mentioned java libraries, we use choco in this project. Choco is based on an event based propagation mechanism with an additional feature of backtracking structures which adds to its supremacy. This gives clear difference between modeling and solving a problem. 4. CHOCO: Choco is an open source software implemented in java program that is widely used for constraint programming and constraint satisfaction. General Features: Choco provides problem modeler that handles a variety of variable types that are integer variables real variables that holds an interval of floats. expressions using variables with the many operators like +, -, /, * and etc. Chocos modeler supports 70 constraints some of them are listed below Arithmetical constraints (integers or real): equal, not equal, greater or equal, less or equal. Refined constraints i .e Boolean operations between constrains. It will verify the relation for a set of variables by defining the sets of tuples in the table constraints. Constraint Programming Solver: Constraint programming solver provides The different types of various domains implementations will be done (enumerated, bounded, integer variables). For constraint propagation several algorithms were implemented (parameterized cumulative, full and bound all different, state-of-the-art AC algorithms for table constraints) Chocos Design: Chocos design provides clear separation between modeling and solving. In the modeling the problem will be expressed and variables and relations are defined. The verification for variable constraints for their potential implementation is done. The API is provided that facilitates how to state a problem as user friendly. In the solving phase, the problem solving is done by Constraint Programming and related information is provided. It handles specific memory management for variables and tree-based search. 5. JAVA: We use choco constraint java library to build the tool. By embedding choco java library with the java programming we create the required exam timetabling tool. Java provides us many features which augments security and has many advantages: Java is designed in such a way that you can easily write the code and debug the code. Java uses the concepts of automatic memory allocation and garbage collection. As java is an object-oriented programming language, it allows objects to work together. The code written in java is reusable. Java is platform independent. This is developed by keeping security in mind. Java augments todays web with security and reliability. Because of these features we use java programming in our project. But we need an INTEGRATED DEVELOPMENT ENVIRONMENT(IDE) to develop a java application. Lots of IDEs are available. In this project EXAM TIMETABLING with CONSTRAINT SATISFACTIO we use MyEclipse IDE. 6. MyEclipse IDE: MyEclipse is a commercially available JAVA EE and AJAX IDE. This is created and maintained by the company GENUITEC. This is built on the eclipse platform. This integrates proprietary and open solutions into the development environment. MyEclipse incorporates open standard technologies to provide a development environment for J2EE, XML, UML and databases. This is an open source IDE to which you can add external jars. MyEclipse allows you to save the valuable time on debugging environment. By using MyEclipse, it is easy to edit and debug the environment. MyEclipse comes with two versions: a professional and a standard edition. The standard edition adds various tools and a number of other features to the basic Eclipse Java Developer version. CHAPTER 5 SYSTEM DESIGN The development process of the Automated Exam Timetabling tool for a University, we use Choco 2.1.0 version which is implemented using Java Programming. The different tasks which are going to be implemented in the process of developing this application are Designing Graphical User Interface(GUI). Data Calculations. Timetable. Choco tool for Constraint Satisfaction. Step1: Designing Graphical User Interface (GUI) This process includes only Graphical User Interface part, that consists buttons, Tables, Dropdown lists and etc. These controls are arranged in the proper order to display them. Look and feel will be implemented in this process. Step 2: Data Calculations Data Calculations part consists of code which results the final output for the Schedule of Exam Timetable. Here we implement the code with logic that works like selection of exams to be held in alternative days. Here we consider all exams of particular course and prepares a logic for Exam Timetable that includes Supplementary and Regular Exams. Step 3: Timetable Timetable process involves in the creation of a schedule that sets the examinations are allocated into venues with limited capacities within an examination period. This includes the following methods. We cannot schedule a session where one student cannot taken two examinations in the same session. The venues capacity should not exceed from the total number of candidates writing the exam in a schedule. Step 4: ChocoSolver ChocoSolver is a java library for constraint programming and constraint satisfaction. Choco will define all the variables of time tabling problem that includes the Constraint Definitions Candidate Information Venue Information Examination information Exam Session particulars. User has to enter constraints and changes to the exams related to the particular exam or venue. Defining the Constraints This program will allow the users to define all necessary constraints according to the exams. The different duration should be separated for all examinations . The examination time and venue of a particular batch should be held in particular date. Venue Partitioning This process considers the number of faculties and venues. Invigilators are allocated to particular venue for the examinations. User interface is provided for the assignment and manipulation of venue partitions to the faculties. In venue partitioning the following points are considered in the Choco Solver The number of students in a venue should not exceed more than the capacity. The sufficient invigilators should be allocated for the each examination hall. The attendance sheet should be provided to the invigilators to confirm the candidate is attended or not. PROBLEMS IDENTIFIED AND THEIR PROPOSED SOLUTIONS: Scheduling an exam time table is very difficult and time taking task because there are many constraints that should be satisfied for ex: at least one day gap should be there in between two exams so that student gets time to revise, there should not be any other exam on the same day which collides with the present exam, room allocation, staff allocation, invigilator allocation à ¢Ã¢â€š ¬Ã‚ ¦. Etc. All this problems are solved in this project, this project saves a lot of time, this helps to schedule exam time table in more user friendly manner. Proposed System: In this project user can add any module to any cohort by using dropdown menus. Mostly we are not sure about the starting date of exams, but in this application user have chance to select the starting date of examinations. Sometimes same module may be shared by some cohorts. In this case we are going to create new time table for the module shared by different cohorts on the same day. So that time can be saved and number of invigilators can be reduced. Some student may have supplementary exams. This supplementary exam and regular exam should not be on the same day or on the consecutive days. Separate schedule is created for these supplementary exams or those should be held with next intake students. This application allows user to add modules to a cohort by using drop down menus. The user can also make changes to the selected modules list. As per the date, schedule and cohort selected by user examination time table is created. As the user is allowed to choose options from drop down list provided, problems that occur due to typing mistakes can be decreased. Application development and deployment: The steps involved in the development and deployment of application involve Formulating the data interpretation scheme that is sufficient to handle all the requirements of the problem converting all data available to data interpretation scheme Next step is developing the scheduling algorithm that is used to schedule the exams. The application should support the numerous last minute changes during its development and deployment easily. Application Uses: The following are the benefits of Automated Exam Timetabling The initial implementation of program requires a lot of time for data entry and constraint specification. We can reuse the database of previous exams for next exams. Assuming that the constraints are specified correctly, the application should produce the schedule that is conflict free. We can schedule the exam timetable in a short span of time. We can make last minute changes in a short span of time. Shortening the exam period can make the expenses spend on conducting the exams (such as buildings, staff, etc.,) come down. The application benefits from its three tier architecture design. Conclusion: Automated Exam Timetabling software is used to schedule the university exam time table. This is reduces time and complexity involved in scheduling the exam time table manually. This document explains about the space and time complexity involved in scheduling the exam. The application developed is user friendly and it is used to give a graphical look and feel to the user for accessing and entering the information. Automated Exam Timetabling provides all the features that are required for scheduling the exam time table. Implementation of this software at different universities reduces the cost in terms of money and time. Future Uses: Automated Exam timetabling can be extended to schedule the university class time table and school time table School Timetabling: This application is used for scheduling the timetables for weekly classes at higher schools. University Timetabling: This application is used for scheduling the lectures of students of different modules in a university such that they prevent students and lecturers from double booking.

COMPUTERS Could one imagine what the world would be like today without computers? For one, I would not be typing this paper right now. Computers were actually developed in early history. The first major use for a computer in the U.S. was during the 1890 census. Two men, Herman Hollerith and James Powers, developed a new punched-card system that could automatically read information on cards without human intervention (Chaney 52). This caused many other people to develop computers for various tasks. Each new computer helped to perform a different function and make it easier. Eventually IBM made a computer that could perform various tasks such as: figure out equations, store data, and draw graphics (Chaney 53). From there the computer industry exploded. Now computers have changed many aspects of life. Computers have had a major effect upon business. One area deals with the advertising industry. It has completely re-arranged the advertising business. Before computers companies used to advertise only on magazines, billboards, and T.V. The internet has spawned a new world for advertising. If anyone has ever been on the Internet; they know that it is a major contributor to this. Instead of companies paying around 1 million dollars to advertise for a 30 second commercial during the Super Bowl; they could just pay a certain amount to be advertised forever on the net. People can also notice the changes of advertising on the T.V., also. Not until the last few years have people noticed that a great deal of the commercials on T.V. are computer-related. These two combined have made the advertising businesses boom. Not only just on the T.V., but also on the net. Another area affected is the stock trading business. Computers have actually hurt the majority of stock brokerage firms. The reason is because computers allow it’s users to have access to the same information the actual brokers have. They can log onto the internet and go to their online firm to download information on stocks. This way they have the knowledge to trade and buy stocks for themselves without paying a certain percent to the broker. People can become a member of online firms such as: Ameritrade, DLJ Direct, SureTrade, and others. Here they can trade for a mere $8-$10 dollars. People also have responded th at they feel more comfortable when they have total control of their money ( Maney 45). A final area deals with the actual computer-related companies.
