Development of an Online Course Portal for a Campus

This project aims at creating a Courses portal for a campus/organization. This allows registered users of the system to join a course available in the site and access the materials published for the course. People can register themselves as students of a course or Faculty for a course.

When a person registers himself as a Faculty, an approval mechanism should be triggered which sends an email to the Administrator for approving the person as a Faculty.

There will be an admin approval page where admin can approve the faculty members for the course.

The course home page should contain the title of the course and a brief description. There will be a discussion board for each course where students can interact, an announcement section, which contains the latest announcements, and a course content section which gives the links for the material available for the course.

For faculty members there will be an extra link for uploading the course content in a zip file format. The course content should be html pages, which should be uploaded in the zip file format.

There should be a mechanism for the faculty members to create a test for the course specifying the test title and a set of multiple-choice questions and duration of time of the test.

Orkut Java

We plan to develop a live chatting module based on the group http://www.orkut.com .We studied the working of orkut in detail..and tried to extract important features in our project.

Basically our project works on LAN while the real orkut works on internet. But the basic idea behind it is the same..that is to provide the user with a enjoyable and good-to-look means of communication.

The real orkut provide the users with lot of options such as add as a friend ,write scraps, add to crush list ,write testimonials, joining communities etc..but we plan to include only the basic options in our project which deal with communication purpose or rather the chatting purpose .

Hence our project will contain basic functions like add as friend, write scraps and uploading photo. Like in real orkut ,user will create his own account containing a unique username and password ,which he only can access .If the user is a new one then he has to fill application form containing his personal information. Then only the user can log on to the system.

The user can write scrap to any member of (our project) orkut at any point of time. He is also eligible to upload the photo of his choice, which can be viewed by all the members of (our project) orkut .The album feature which is present in real orkut is not taken in our project as there is as such no need of it.

Also users are allowed to upload only one photo of his choice, which will be displayed on his homepage .The user, on finding his friend as member of(our project) orkut can send a friend's request to him. Now it depends on user's friend whether to accept him as a friend or to reject him..this is totally in hands of the user's friend!!!

All the user's friends will be displayed on rightmost top of our screen.so that he can know who are online and who are not?.The user on finding a person to be online can write scraps to him.(Even if user's friend is offline, user can write scraps to him.these scraps will be viewed by user's friend when he will access his account).

Scraps can be written by visiting the profile of his friend and writing scraps in his scrapbook..Similarly a person can view scraps written to him in his own scrapbook.User is eligible to delete the scraps written to him and the scraps written by him. Other's scraps can't be deleted!!!!!!!

If the user is currently online, then he has to refresh the page constantly so as to view the new changes made to his account(not his personal info)for eg :if new scrap is written by his friend, then the user has to refresh his scrapbook page so as to view this new scrap.thus chatting can be done on orkut.

The user ,at any point of time, can change his personal information or his photo!!!

To implement this project, sufficient knowledge of JAVA is needed. Along with that, knowledge of socket programming and JDBC is must. Lets see how they are implemented.

• Socket programming is needed to connect PC's together and exchange information between them.

• The code of the project has to be done in JAVA hence knowledge of JAVA is must!!!!

• Also all the information is to be stored in database, hence to connect the database with our source code, knowledge of JDBC is needed.

SUDOKU

The main aim of the project is providing security to the PC. The project develops a system, which prompts the user to enter a password during the booting process itself. The user in cannot skip this process anyway once the software is installed.

Only by entering the correct password we can enter to the next screen or else the system reboots. This prevents any illegal entries into the system.

Any changes in the system can be brought only when the correct password is entered. Then we can go to the setup and change the password and encryption key if we require.

Thus the system which have Windows98 as it's operating system is completely protected by the user by a password which he has entered during the setup of the software and no user of the system can skip this password checking.

This confirms that the system is not being hacked and this is the main objective of the software.

The project "SUDOKU" game on student based PC provide flexibility and also to have abroader outlook a guest mode is to be implemented for infrequent or temporary accessories of the host's computer Since it is a student based version only a limited number access the PC.So we limit the number of users .

The project consists sample numbers in the correct position and the player have to fill the remaining numbers in the correct order to win the game.The other features mentioned in sample,about statements.

So the "SUDOKU" game is more easy as the ultimate aim should be developed. The project is object oriented one.So the primary requirement is the use of store and manipulate the numbers.

In order to satisy the infrequent users a guest mode is required with limited but necessary facilities.

The most important requirement is that the software developed should be user friendly and unreachable.

 

Insurance Database

The current authentication and verification process for CTPL COCs uses a centralized database system called COCAS (COC Authentication System). COCAS was developed by SQL Wizard and is owned by the Philippine Insurers and Reinsurers Association (PIRA).

When CTPL insurance is sold to the registrant, the insurance company encodes insurance and vehicle data into COCAS using the Internet. The registrant then passes through a verification step at a station (handled by DTECH Management Inc) located in LTO District Office premises, where the authenticity of the COC is verified.

At this stage, a DTECH representative connects (using the internet or SMS) to COCAS, encodes COC and vehicle information, and affixes a sticker on the COC if verification is received.

The registrant then submits documents to the LTO evaluator, where the evaluator checks whether the COC has indeed been verified by ensuring that a sticker is present, before proceeding with the registration transaction.

The insurance firms eventually declare the number of COCs they have issued to the IC and pay the corresponding taxes to the BIR.

Consider the Insurance database given below. The primary keys are underlined and the data types are specified:

PERSON( driver-id :string,name:string,address:string)

CAR( Regno :string,model:string,year:int)

ACCIDENT( report-number :int,date:date,location:string)

OWNS( driver-id :string,regno:string)

PARTICIPATED( driver-id :string, regno :string, report-number :int,damage-amount:int)

1. create the above tables by properly specifying the primary keys and the foreign keys

2. Enter atleast five tuples for each relation

3. Demonstrate how you

a. update the damage amount for the car with a specific regno in accident with report number 12 to 25000

b. add a new accident to the database

4. Find the total number of people who owned cars that were involved in accidents in 2002.

5. Find the number of accidents in which cars belonging to a specific model were Involved.

6. Generation of suitable reports

7. Create suitable front end for querying and display the results

Security System For DNS Using Cryptography

The mapping or binding of IP addresses to host names became a major problem in the rapidly growing Internet and the higher level binding effort went through different stages of development up to the currently used Domain Name System (DNS).

The DNS Security is designed to provide security by combining the concept of both the Digital Signature and Asymmetric key (Public key) Cryptography. Here the Public key is send instead of Private key.

The DNS security uses Message Digest Algorithm to compress the Message(text file) and PRNG(Pseudo Random Number Generator) Algorithm for generating Public and Private key.

The message combines with the Private key to form a Signature using DSA Algorithm, which is send along with the Public key.

The receiver uses the Public key and DSA Algorithm to form a Signature. If this Signature matches with the Signature of the message received, the message is Decrypted and read else discarded.

Pro-net Communication

Intranet exploits the incredibly popular and low cost internet tools to gain strategic advantage over competitors, cut costs and improves operational effectiveness. An Intranet typically has 3 features lacking on the Internet.

• Speed - broad bandwidth

• Security - private internal network ( LAN /WAN),protected from

Internet users by a firewall.

• Control - enterprise network management to ensure reliability.

The Intranet can be viewed as an information utility for the enterprise. It doesn't matter whether we are using the Mac, Windows or a UNIX workstation - we plug into the Intranet and find out what we need, from document to email to data to audio and video.

Corporate and department information is accessed via the standards the Internet: e-mail (SMTP), WWW , File transfer (FTP) and other Internet services.

Intranets overcame many of the organizational and technology barriers that were created in the past.

Web solutions overlay the department LAN systems, with their own security and domains, and make information available to everyone in the corporation - without changing the LAN security structures. That provides a huge benefit.

Trackerz

Trackerz is a B2B is the term which informs us about the business. This concept is build related to business activities.

The main criteria of the project is to build a web portal for transactions like online shopping ,tenders, auctions, classifieds, Admin controls this web portal and users access through unique id,through the id user can select the product and purchase by entering the details of the transaction. In short we can say that it is a B2B portal.

Business-to-business ( B2B ) is a term commonly used to describe commerce transactions between businesses, as opposed to those between businesses and other groups, such as business-to-consumers (B2C) or business-to-government (B2G).

More specifically, B2B is often used to describe an activity, such as B2B marketing, or B2B sales, that occurs between businesses and other businesses.

The volume of B2B transactions is much higher than the volume of B2C transactions. The primary reason for this is that in a typical supply chain there will be many B2B transactions involving subcomponent or raw materials, and only one B2C transaction, specifically sale of the finished product to the end customer.

For example, an automobile manufacturer makes several B2B transactions such as buying tires, glass for windshields, and rubber hoses for its vehicles.

The final transaction, a finished vehicle sold to the consumer, is a single (B2C) transaction

Portable Media Player

To provide a media player interface on Bluetooth enabled mobile device. In this module there will be a media player to play songs on a desktop and its instance interface on mobile device from where we can control playback remotely.

Streaming with above media player. Streaming of any song will be done by media player when it gets a request from its counterpart player on mobile device to do so. With this a person can listen to any song from media player library by streaming done with Bluetooth protocol .

Aim :

1. To learn interaction between a desktop and a Bluetooth enabled mobile device.

2. To provide a virtual command prompt on mobile device to perform various tasks remotely.

3. To provide new user experience for music freaks so that they can take advantage of their giant music library (that’s on PC) from anywhere within range of class B Bluetooth (30 feet).

4. To learn about all the technical restrictions that a developer can face while learning mobile development using JAVA.

Recently, MP3 become popular in this generation. Most of the software companies develop so many types of player which support MP3 file (e.g. Winamp, Window Media Player, Real, RealOne, etc). But there is not all of the software which are suitable for all different users.

Pomp is basically a facility for music lovers to control playback of mp3 player right from there Bluetooth enabled phone. Without a phone , it can work as a standalone mp3-player on system. This mp3 player has inbuilt ID3 tag editor.

To achieve this we have chosen java as the implementing language because java is platform independent so what will get can be run on any platform.following java’s “Write once run everywhere” title.

Benefits of the system

1. Fast standalone mp3 player.

2. Save user time controlling playback from their mobile doing anything else.

3. Facility to save play-list files.

4. ID3 tag editor to edit mp3 metadata.

5. Made in java, hence is extensible, platform independent, robust.

Objectives

The main purpose of POMP is to produce an audio (MP3) player that can be suitable for different level user. The goals of POMP are:

Provide a platform to play audio (MP3) file

Provide different interfaces for different level users

Support playlist (M3U) file

Provide playlist management

General Requirements

The following general requirements were laid out for our project named POMP:

• The player can play audio (MP3) file 7

• The player can provide some necessary function of playing audio (MP3) file, such as previous, next, random, repeat etc.

• Users can choose their interface for their level

• Users can add new songs to the playlist or manage their playlist

• All user’s data and playlists could be stored electronically

Rich Internet Application for Weekly Automatic College Timetable Generation

RA college timetable is a temporal arrangement of a set of classes and classrooms in which all given constraints are satisfied. Timetabling has long been known to belong to the class of problems called NP hard. This project introduces a practical timetabling algorithm capable of taking care of both strong and weak constraints effectively, used in an automated timetabling system.

Rich Internet applications (RIA) are web applications that have the features and functionality of traditional desktop applications. RIAs typically transfer the processing necessary for the user interface to the web client but keep the bulk of the data (i.e., maintaining the state of the program, the data etc) back on the application server. We have used the Google Web Toolkit, which is RIA framework, for the same purpose.

Our project reduces the overhead on server of rendering client’s UI components and makes room for processing time of Timetable Generator Algorithm. Our Timetabling Algorithm is main component of our project which produces the HTML based weekly timetable sheet as the output.

Our project takes various inputs from the user such as Teacher List, Course List, Semester List, Room List, Day List and Timeslot as well as various rules, facts and constraints using web based forms, which are stored in XML based knowledge base.

This knowledge base serves as input to our Timetable Generator Algorithm residing on server machine. Both GWT Client Side UI code and our algorithm are written in JAVA, which makes our project platform independent. Further benefits of choosing these frameworks are explained in later part of report with practically acceptable results.

Planning

An algorithm for constructing a timetable has to assign instances of the different resource classes to the event class instances. Some of these assignments are predetermined and cannot be changed, and some have to be done during the planning phase. To construct a timetable, one of the views mentioned in above section is used. In the school timetabling case our algorithm might use the class view to assign a subject, teacher and room to a lesson. In this case the class is fixed and the other instances have to be assigned to. Additionally, a time interval has to be assigned to each event class instance.

For each viewing perspective there are as many timetables as instances of this class to be planned exist. If we have t teachers at a high school, for example, t different teacher timetables belong to them. That is, if there exist l lessons in a high school timetabling problem, furthermore t teachers, r rooms and c classes, the number of instances of event classes including all views will be (t+r+c)×l. The timetables of the instances of one planning class contain all information necessary to construct the timetables for the instances of the other planning classes: i.e. the timetables of the different views can be mapped to timetables of other views. In the school timetabling case the t teachers’ timetables can be mapped to the r rooms’ timetables

That is why it is usually sufficient for a timetabling program to save the timetables of one resource type only. This avoids data redundancy caused by storing the same event information in different places, i.e. from different views.

Nevertheless, to be able to check constraint violations, translations to other views have to be done, for example to compute the number of assigned lessons of a teacher when working with the class view. Otherwise expensive computing time has to be accepted in order to compute the necessary information.

Support Vector Machines For Face Recognition

Neural networks have been applied extensively in computer vision and pattern recognition. Support vector machines have been recently proposed as new kinds of feed-forward networks for pattern recognition .

Intutively , given a set of points belonging to two classes , a SVM finds the hyperplane that separates the largest possible fraction of points of the same class on the same side , while maximizing the distance from either class to hyperplane.

This hyperplane is called optimal separating hyperplane which minimizes the risk of misclassifying not only the examples in training set , but also the unseen examples of the test set .The SVM is essentially developed to solve two class problem.

The application of SVMs to computer vision problem have been proposed recently . SVM is trained for face detection where the discrimination is between two classes : face and nonface , each with thousand of examples.

It is difficult to discriminate or recognize different persons by there faces because of similarity of the faces. In this project , we focus on the face recognition problem , and show that the discrimination function learned by SVMs can give much higher recognition than the poular standard eigenface approach or other approach .

After the features are extracted , the discrimination functions between each pair are learned by SVMs . Then the disjoint test set enters the system for recognition .

We will construct a binary tree structure to recognize the testing samples . We will develop a multi-class recognition strategy for the use of conventional bipartite SVMs to solve the face recognition problem .

Objective :

• Efficiently applying SVM to the n-class problem of face recognition

• Figuring out training and/or image preprocessing strategies

• Comapring how SVMs compare to other techniques

SOFTWARE AND TOOLS / TRAINING DATA :

• Thorsten's SVM Light

• Java Netbeans

• Visual Studio

• Image datasets for training and testing

 

SMTP Mail Server

The "SMTP MAIL SERVER" deals with identifying multiple users with in the same login and enabling them to send and receive mails. The current environment requires a login for each user to handle all mails related information. But more than one user can't use the same login and personalized security on mail transmission and reception.

Hence it becomes necessary to have a login for every user to communicate with each other by sending and receiving mails that are currently available in the default UNIX environment. A utility that will allow multiple clients to login under the same login name and have personalized mail information e developed.

Features of the project:

• Registration of mail ID's

Comparison and Simulation of Different Queuing Models

Queuing Theory is a collection of mathematical models of various queuing systems. It is used extensively to analyze production and service processes exhibiting random variability in market demand (arrival times) and service times.

In queuing theory , a queuing model is used to approximate a real queuing situation or system, so the queuing behavior can be analyzed mathematically. Queuing models allow a number of useful steady state performance measures to be determined, including:

The Average number in the queue, or the system, the average time spent in the queue, or the system, the statistical distribution of those numbers or times, the probability the queue is full, or empty, and the probability of finding the system in a particular state.

These performance measures are important as issues or problems caused by queuing situations are related to customer dissatisfaction with service or may be the root cause of economic losses in a business. Analysis of the relevant queuing models allows the cause of queuing issues to be identified and the impact of proposed changes to be assessed.

Markovian queueing model :-

If the arrival process is Poisson and the service time distributions are exponential for a queuing model then it is said to be a Markovian queuing model . 

A Markov chain is a sequence of random variables X 1 , X 2 , X 3 , ... with the Markov property , namely that, given the present state, the future and past states are independent. Formally,

Birth-death process :

The birth-death process is a special case of continuous-time Markov process where the states represent the current size of a population and where the transitions are limited to births and deaths. Birth-death processes have many applications in demography, queuing theory, performance engineering, or in biology. When a birth occurs, the process goes from state n to n+1. When a death occurs, the process goes from state n to state n-1. The process is specified by birth rates {? i } i=0.8 and death rates {µ i } i=1.8 . 

Applications Of Queuing Theory

Queuing Theory has a wide range of applications, and this section is designed to give an illustration of some of these. It has been divided into 3 main sections, Traffic Flow , Scheduling and Facility Design and Employee Allocation . The given examples are certainly not the only applications where queuing theory can be put to good use, some other examples of areas that queuing theory is used are also given.

Traffic Flow

This is concerned with the flow of objects around a network, avoiding congestion and trying to maintain a steady flow, in all directions.

Queueing on roads

Queues at a motorway junction , and queueing in the rush hour

Scheduling

Computer scheduling

Facility Design and Employee Management

Queues in a bank

A Mail Sorting Office

Trade Service Engine

An organization/company will have a number of products and services they may offer to their customers. Depending on the type of business or service offered the customers may have several doubts/complaints/problems.

The "Online Business Service Engine" helps to accomplish this task of solving and clarifying the customers' queries. This product facilitates the user to submit online complaints independent of the system

The "Business Service Engine" can be used by a business organization to provide online support to its customers. This may include questions about their services or even complaints the customers may have. Although a manual system can be done, time plays an important role in customer satisfaction.

A customer always expects services to be offered as soon as possible and the organization is responsible for making sure its customers stay satisfied. As most organizations are going, or are already online, the "Online Business Service Engine" will prove an added advantage to them in this internet world.
