The software provided features like sending/receiving emails, ability to attach files/ save attachments etc. The email system also included registration and password protection facilities. Other options include Address book option, creation of mailing lists and nicknames for the frequently used emails. 

Developed a Compiler (Front End and Back End) based on the Static Single Assignment Form for a subset of the Pascal Grammar. Global Common Sub-expression elimination was performed on the Intermediate representation. A Register Allocator was also implemented for the compiler. The graphs were rendered using VCG visualization tool.

Analyzed the suitability of several static and dynamic priority algorithms for real time systems. Some of the algorithms analyzed were: Rate Monotonic, Earliest Deadline First, Total Band width server etc. The project also dealt with algorithms for SMP architectures like Hierarchical Band width server, and Open Virtual Systems. Finally the project also highlighted the features of the Real-Time Java Specification.

As part of the Operating Systems course, implemented the producer consumer problem using POSIX threads. Two solutions were implemented one using named Semaphores and the other using Message Queues. The implementations were used to compare the performance of shared memory v/s Message queues. System V performances was also measured and contrasted with the POSIX results 
for each case. In another assignment, POSIX Signals and shared memory was used to simulate Inter process communication.

Developed a Java based information retrieval system to analyze the link and content structure of a given web page. The user creates a list of his favorite sites and the system periodically parses the site recursively and sieves the link and the content structure. This data is then used to find the difference between the current version of the site and its previously visited version. Statistics like new links/contents added/deleted are displayed. This tool could also be used as an agent that keeps track of a user’s favorite web sites and update him/her if new contents/links are added or deleted.

Presented a survey paper on the Architectural Patterns. The paper dealt in depth architectural patters like Model View Controller, Broker, Layered Pattern etc. Each pattern was described in terms of the forces that they resolve, behavior-using CRC diagrams and several scenarios where they are used.
