Development Of An Automatic Class Scheduler

Development Of An Automatic Class Scheduler Regarding the rapid growth of the number of students and the increasing number of courses offered in school, colleges and institution, the task of scheduling classes to fit into timetables and into existing facilities is becoming much more complicated. At the present time, class scheduling not only needs to fit the courses offered but also has to be performed based on many factors, such as availability and capacity of the room, cost occurred when the rooms are engaged by any courses, losses occurred when the rooms are left out, etc. Class Scheduler is an easy to use single or multi-user application for scheduling students classes. The software is ideal for schools, colleges and other institutions that must create class schedules. Class Scheduler can be used by a single teacher or by a group of students to schedule classes. The idea behind Class Scheduler is to increase the productivity of classroom administrators by automating the class scheduling process by automatically setting up course times and assigning rooms and instructors. We can view course schedule, student schedule, instructor schedule and classroom schedule online. We can also resolve clashes without effort, and preferences of staff and students action with ease and serves a clash-free and error-free timetable. It also saves time and labour. 2. OBJECTIVE OF THE STUDY Timetable creation for has always been an error-prone task, normally resulting in multiple iterations of creation and proof-reading. Changes desired by teaching staff, changes of course locations etc. also require an adaptation of the previously created timetables. Traditional approach to generation of timetable had great difficulties due to large search space which were created as a result of number of variables that need to be considered in such problems. Hence the objective of this project is to automatically generate time tables for the betterment of the teaching staff students. PROBLEM STATEMENT The manual system of preparing Time Table in colleges with large number of students is very time consuming and usually ends up with various class clashes either at same time or with same teacher, having more than one class at a time. These are just due to common human error which are very difficult to prevent in processes as these. To overcome these problem people usually end up making injudicious use of classrooms and labs. To overcome all these problems we propose to make an automated system. INTRODUCTION CLASS SCHEDULER is the online timetable generator for schools, colleges and any other institutions that must create class schedules. CLASS SCHEDULER offers functionality for generating timetables (for students or teachers) as well as overview timetables, i.e. all courses in a certain semester for any given degree. This study is expected to solve those problems and improve the qualitative aspects of generating schedules as follows: Shortening the time in establishing the timetables with computer assistance and better information. Easing the procedure of establishing the timetables Establishing the timetables according to maximize facilities utilization and instructors preferences. Developing an interactive computer link to facilitate data output and the interpretation of the results. DESCRIPTION OF THE SYSTEM The project aims at developing an automated Time Table generator. The system will take various inputs like details of student, subjects, classrooms and teachers available. Depending upon these inputs it will generate a possible Time Table. Making optimal utilization of all the resources such as rooms and labs and distributing classes in a way that will best suit any of constraints or college rules. List of subjects may include elective as well as core subjects. Features: Simple Data Entry: It is quick and easy to enter information of all subjects, years (FE, SE, TE, BE), courses ( computer science, extc, bio-medical), Rooms and teachers. Automatic generation: In few minutes, the program generates a complete timetable that fulfills all your requirements. The program follows all organizational requirements such as selection for number of working days of the week, zero (attendance) period insertion. Subjects could be entered considering subject in which classroom, single or double duration consecutively, periods per week per subject. Periods could be entered with considerations of maximum number of consecutive periods per teacher. Teachers could be placed with considerations such as class should not be assigned when teacher is not free i.e ABC teacher should not be given any class on Monday. XYZ teacher should not get 1st and 2 period on all days etc. Also considering teachers getting x number of maximum periods, minimum/maximum periods per day, limit number of consecutive periods. Automatic Reports for Printing, Website: Reports for website could be generated for the following: Summary timetable for classes Summary timetable for teachers Summary timetable for rooms year wise time table Teacher wise time table All classes assigned to a teacher ( no. of periods per week bifurcations) Total number of periods subject wise Checking of total Working Hours per week details for the teachers PROCESS FLOWS ER-DIAGRAM DATA FLOW DIAGRAM Context Level Diagram Level 1 DFD CLASS SCHEDULER is a system in which automatic timetable is generated by considering various constraints in the system. It also provides the login facility. System takes the required data provided by class coordinator and performs function to generate time table. A professor logs in and can view the required time table. Professor can request for modification which is forwarded to system by coordinator system generates the alternate timetable, coordinator views the generated timetable and accepts or rejects the modification. If modification is accepted then the received timetable is stored in database. If the request is rejected then it is informed to requestor that request cannot be processed. This all activities are shown in the data flow diagram (Level 0) also called as context free diagram. Level 2 DFD INPUTS: It takes various input required by system that are professor information and various data required about that professor. It also takes input of subjects and the relevant information required. The classroom and lab information are also provided. This all data are provided by coordinator. GENERATION OF TIMETABLE: It takes the information provided by the coordinator and consider the various constraints provided. It generate professor schedule and the respective schedule is entered in the class schedule, while generating the schedule it also checks that no timeslot redundancy occur i.e; no single slot is allotted to a two or more professor. Two type of timetable is generated: class wise and professor wise, this both timetable are stored in database by this process. This stored timetable is used as and when required by the users. DISPLAY TIMETABLE Whenever user login the system it provides various option of displaying timetable. User select the required options , the request is then analyzed by the system and in accordance to the request made the required timetable is displayed. The system provides the online view of timetable. MODIFICATION After the time table is generated the provision is made to view them in various options , timetable is displayed as per the user requirement. The professor views the timetable and if required he/she request for modification. This modification request is forwarded manually to the coordinator which in turn is forwarded to the system. The system then generates the alternate timetable .this alternate timetable is then viewed by the coordinator. He then decides whether the change is propagated or the request cannot be considered. If request is not considered then it informs the requestor about it. STRUCTURE CHART DIAGRAM USE CASE DIAGRAM Display timetable Login Generate timetable Modify timetable Professor student coordinator Use cases involved in the system are: LOGIN: User logs in the system by entering user name and password. If user name or password is invalid, the system display error message. GENERATE TIMETABLE: The system generates the timetable according to the input data provided to it by considering different constraints. MODIFY TIMETABLE: The system takes the request from user and generates new timetable. DISPLAY TIMETABLE: The system displays the timetable in a format requested by the user. Actors involved in the system are: PROFESSOR: Professor views the timetable online which is generated by the system and if it is inconvenient for professor then he/she requests for modification in timetable. STUDENT: Students view and follow the timetable generated by the system. CO-ORDINATOR: It is an actor who is responsible for managing the system. 1 UC1 Login Brief Description UC1.1 This use case helps user to login to the system.

The model has to be able to reduce the number of activities in the scheduling process.

Pass The Weed :: essays research papers

Pass The Weed   Ã‚  Ã‚  Ã‚  Ã‚  The cries of conservatives across America has grown to a riotous roar. The problem is that the long-standing and unjust prohibition of the psychoactive drug marijuana has been lifted by voters in Arizona and California. Under the new law, doctors can prescribe marijuana to those patients who can possibly benefit from the drug's medicinal purposes. Used for alleviating pain and suffering, the drug can provide needed relief for many people. However, to the concerned, it appears that with the new propositions government has granted permission to posses and consume a drug that has been banned for decades. The â€Å" smoke† has yet to settle in Washington, but a reaction to the new laws from the federal government seems unlikely. Optimistic supporters hope that similar policies and propositions will soon come to voters in other states.   Ã‚  Ã‚  Ã‚  Ã‚  The debate over the legalization of Cannabis Sativa, more commonly known as marijuana, is currently one of the more heated controversies in the country today. The drug has been unrightfully prohibited since the 1930's for its dangerous effects. However, earlier and more primitive cultures were able to safely explore marijuana's usage for both medicinal and hallucinogenic properties. The usage of marijuana has existed for thousands of years in many countries world wide and can be documented as far back as 2700 BC in ancient Chinese writings. In the earlier cultures, marijuana usage was accepted and its effects documented. However, the United States government overlooked all of the information and banned the drug. Recently, however, there has been a resurgence in the opinion of the drug's positive medicinal purposes.   Ã‚  Ã‚  Ã‚  Ã‚  Studies on the medicinal uses of marijuana have been conducted on many patients that suffer from various health problems. In patients with the AIDS, the drug served as a beneficial way to stimulate appetite. Thousands of AIDS patients already use marijuana illegally for this condition and have reported excellent results. For those AIDS victims, marijuana can reduce the nausea, vomiting, and loss of appetite that are common to the syndrome. Another medical function for marijuana is to combat glaucoma, the leading cause of blindness in the United States. Glaucoma is an eye disease that results from pressure that builds up over time and causes great pain and vision loss to sufferers. In the glaucoma patients, marijuana can aid in relieving the intraocular pressure on the eyeball, and thereby alleviate the pain and sometimes stopping the progress of the condition. Multiple sclerosis is another incurable condition that could benefit from the legalization of marijuana. The disease disrupts the normal functioning of the nerves in the brain and the spinal cord.

Medea Greek Mythology Essay

When Medea decides to take matters in to her own hands, about punishing the people who have done wrong to her, she is accused of wanting not justice—vengeance. Because I am not a native of neither Corinth nor Colchis, I have my own view about her motives. However, I would agree with the Corinthian Women, Medea is seeking vengeance; not justice. Some people might argue that Medea is seeking justice. When in actuality, Medea wants vengeance. The opposition would say justice took place because the Gods allowed Medea the time to perform her various acts. Although these things happened Medea turned to vengeance when she took it upon herself to kill Creon and his daughter Creusa. Even the chorus, the â€Å"ideal spectators†, implies that Creon is a poor king when, after he banishes Medea, the First Corinthian Woman sympathizes, â€Å"I am of Corinth and I say that Corinth is not well ruled. †(1. 214-216). This quote gives us proof that Medea has some sort of reason to seek revenge on Creon. However she lets her hatred exceed its boundaries and allows herself to take the lives of the King of Corinth and its Princess all because they chose Jason over her. In addition, her actions all prove that she wants Jason to do more than pay for hurting her. She wants him to suffer at the fate of her own children. Her revenge was selfish. Medea involved the two things she knew would hurt Jason the most—her own children. According to the First Corinthian Woman, â€Å"It would be better for you, Medea if the earth opened her jaws and took you down into darkness. But one thing you will not do, for you cannot, you will not hurt your own children, though wrath like plague-boils aches, your mind in a fire-haze bites the purple apples of pain. No blood-lapping beast of the field, she-bear nor lioness, nor the lean wolf-bitch, hurts her own tender whelps; nor the yellow-eyed, seythe-beaked, and storm shouldered eagle that tears the lambs has ever made prey of the fruit of her own tree. †(2. 115-126). Keep in mind that the Corinthian Women are the conscious of Corinth. Through this quote the First Corinthian Women has stated that Medea could not harm her own children. She even gives examples of the most dangerous predators that don’t even harm their own young. This is evidence that Medea went beyond the state of justice; but she went well into the state of vengeance. Medea knew what she was doing and quite frankly she could care less about anything other than what she thought of what was seeking revenge on Jason. In conclusion, vengeance was sought by Medea. She went above the fact of teaching Jason a lesson; she even stated she hated Jason more than she loved her children. Answer this question is what Medea has done entertaining or morally instructive?

Pride and Prejudice by Jane Austen Essay - 899 Words

Pride and Prejudice by Jane Austen From the start of Pride and Prejudice it is clear that marriage is one of the most important aspects of the novel with the famous opening line reading It is a truth universally acknowledged, that a single man in possession of a good fortune must be in a want of a wife. This opening line tells us about the plot and Mrs. Bennett fills in the gaps in the rest of the first chapter with Mr. Bingley taking on the role of the single rich man and the wife being anyone of her five young daughters. We also see the urgency of Mrs. Bennett to have her daughters married, To understand this urgency one must have an understanding of the way things were in the nineteenth†¦show more content†¦Neither of these jobs provided a decent wage and they also lowered the social standing of young women as striving for independence was frowned upon. Higher education was unavailable to women so they could only reach a certain level of education and this level would not gain them a decent job so the m ajority submitted and conformed to the social expectation and aimed to marry a rich man. The actual relationship entailed by marriage was not very important to most women with many different reasons for marriage being used such as Financial security, Mutual interests, affection, and lust. For Jane Austin the perfect marriage is one based on love and affection rather than a marriage based on financial security like that of Charlotte Lucas or a marriage of Lust like the marriage between Lydia and Wick ham. Jane Austens ideal view of marriage is like that of Darcy and Elizabeth who built their marriage Love. Charlotte Lucas who married Mr. Collins simply for the security she would receive with out any regard for the life she would have to live with an obnoxious, arrogant and self-absorbed fool. The idealistic marriage that was based on a relationship of true love was a rare thing as most women like Charlotte were willing to settle for someone they didnt even like if it would mean financial securityShow MoreRelatedPride And Prejudice By Jane Austen Essay1724 Words   |  7 PagesThe 18th century novel, Pride and Prejudice, by Jane Austen, is a fascinating book about a young woman’s struggle with family and love.
