Project Goal is to selectively invalidate the cached results only of those queries whose results are actually affected by the updates to the underlying index.
Cached results of queries that are unaffected by the index changes will continue to be served.
We formulate this as a prediction problem, in which a component (CIP) that is aware of both the new content being indexed and the contents of the cache, invalidates cached entries it estimates that have become stale.
Cuckoo Hashing is relatively new approach used for solving collisions in hash tables. This technique demands an increased number of memory accesses, due to the recursive insertion nature of the Cuckoo hashing scheme. In order to reduce the number of memory accesses a new feature was added to the regular Cuckoo hashing Parallel Cuckoo hashing, meaning that in insertion scenario of multiple different elements, the insertions may be done simultaneously and that may bring to significant reduction of memory accesses.
Audio Processors are widely common among home entertainment products and professional audio equipment. They intentionally alter an auditory signal into a form of a new signal for useful purposes such as filtering/enhancement and other effects.
Storing information on a distributed computer system has many benefits. However, should one want to implement such a system, it is necessary to verify that the information and commands are transmitted and received properly by all the computers. In order to perform certain operations, such as writing or reading data, or performing algorithms on the distributed system, each computer must know the stage of the algorithm which needs to be completed at any given time to ensure the synchronization of operations.

In order to guarantee a constant worst-case operation times, nowadays hash table schemes make usage, besides the main memory, also of a content-addressable memory(CAM) device; a small and expensive memory chip that supports parallel lookup operation to all its memory words. The CAM is used to store overflow elements that no free space was found for them on insertion (in the main memory) up until the guaranteed constant worst-case operation time. As the CAM device is extremely expensive, it makes sense to move elements back from the CAM to the main memory whenever a space gets available as a result of a deletion operation. Thus, there is a need to maintain much smaller CAM. In this project we will learn, simulate and compare various strategies to move back elements from the CAM to the main memory.
The project goal is to implement a wireless sensor network operating dynamically, with minimal power consumption.

Cognitive Radio Networks (CRN) provide new horizons to the next generation of wireless communications. The CRN can adapt to the environment and act intelligently within the boundaries of the previously defined knowledge. In order to adapt to new situations it needs to modify its behavior in response to new situations. For that purpuse the CRN must learn.
Learning requires some method for assessing the performance of the Cognitive Engine and, based on that assessment, the knowledge should be modified. In this project we modeled the learning mechanism of the CRN and proved its effectiveness.
As network bandwidth increase , network servers (e.g. Web, Mail etc) create exceedingly large log files , Log requires human inspection for analyzing incidents as well as getting insight into the server operation for tuning,Inspecting very large log files verbatim by humans is impractical .Simplistic filtering (a-la grep) requires going over the entire file for every filter.,which is very time consuming .The problem of searching in such files resembles the Web Search problem were it is prohibitively long to search all the data simplistically.
In this project we plan to implement a new type of Index to the VLTFV Application that supports fast creation of filtered view of large text files using a Web Search Indexing technique. The implementation is in Microsoft .NET and C#.

Timely and accurate statistics about the
web-pages are becoming increasingly important for academic and commercial use.
Some relevant questions are: What percentage of web pages are in the .com
domain? How many pages are indexed by a particular search engine? What is the
distribution of sizes, modification times, and content of web pages?
In order to answer these questions we need to
estimate the size of certain sets of web pages. In this project implemented and
run a "webwalker", which is a technique for sampling web pages using a random walk on
the web. The random walk surfs the web "at random". At each step it
either follows a random link from the current page, or follows a random link
that enters the current page "in reverse".
In this project we built an library which translates the different encoding types into Unicode standard using UTF-8 encoding. The application receives a webpage, recognizes its encoding and finally translates the page into utf8 if necessarily. Analyses show that the recognition mechanism can detect encoding on 92 percent of the web pages.

RSE is a selective tool, meaning only records that were added to it can be found, so the user chooses which records are added to it and can be found in future searches.
The fast rate of growth in information compels us to find ways to store and share our files, sometimes sensitive files, with others. < ?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
The most comfortable way to share files in this day and age is over the Internet. But the internet conceals a lot of security holes. One's sensitive information may reach unwanted hands.
The goal of this project is to allow the user to store his files on a content server and then access these files from everywhere and grant permission to others to fetch them, and doing that all in a secured fassion.
The first one is synchronous collaboration (instant messaging) where the users chat online but the content is not recorded, or asynchronous collaboration (email, discussion forums etc) where the content is recorded but the users do not get the feeling of online talk. In this project, we implemented the best of all worlds.

TTA is a lossless compression codec. The compression is from the familiar WAV files to TTA format. The compression algorithm is designed especially for audio files, allowing high compression rates and bit to bit restoration of the original file. The result is a small but effective program that compresses audio files to 30%-70% of the original size. Our goal was to take the source code of the TTA project, and accelerate it
In a multicast protocol, several processes form a multicast group. Each process in the group exchanges messages with the other group members. In a secure implementation, where every message is digitally signed by its creator, each group member must hold public keys corresponding to the other members. When a new member joins the group, its key must be propagated among the other processes, and the other processes must send their keys to the newly joined member. Conversely, when a user leaves the system, the corresponding public key should be deleted from the other users' databases. The project's goal is to design and implement an efficient dynamic membership protocol for such a scenario, in a hostile environment. The project will be developed in Java, as an extension to an existing system.
This project based on analysis of a new routing algorithm in comparison with old algorithms, that being used today. A special computer network model was build, in order to provide analysis.

The project simulates several search algorithms in peer-to-peer networks. These are Gnutella like networks with large number of nodes and no centralization. Each node has some resources shared with the network. The network is not a real physical network, it is an overlay graph over an existing network, usually the internet, in which each node has only 3~20 neighbours.
Prisoner's Dilemma is very famous concept in game theory in which players may choose to help or betray each other each turn of the game. According to the rules of the game cooperation is rewarded, betrayal is rewarded more, but mutual betrayal is punished. There are several known tactics for this game like 'Always cooperate', 'Always betray', 'Tit-For-Tat', etc%85 The spatial version of the game takes place on a grid in which each cell represents a player. A player that gains a certain amount of point can breed offspring that will occupy adjacent grid cells. A player that loses too many points dies. Running the spatial game for several turns provide animation that resembles that of the Game of Life.

We have made an extensive research to find the best signature comparison metrics and find a retrieval algorithm that works according to a user defined sensitivity.
The Goal of this Project was to create a Platform for testing 3D Graphic Algorithms. This Platform enables the user to create new Profiles (which means to set a new 3D Graphic Algorithm and it's parameters as one unit), to run the Algorithm and to watch the results. The parameters for every Algorithm might be numbers, strings, prefixes and of course 3D Objects files. In order to make the Platform more efficient I implemented a 3D Viewer that splits the application screen for two panes, one for Input Objects and the other for output Objects. The user can use the mouse to move, scale and translate the Objects at both Input and Output panes, he also can edit%5Csave the parameters of every Profile and much more..
Reinforcement Learning (RL) addresses the question of how an autonomous agent that senses and acts in its environment can learn to choose optimal actions to achieve its goals. This very generic problem covers tasks such as learning to control a mobile robot, learning to optimize operations in factories, and learning to play board games. Each time the agent performs an action in its environment, a trainer may or may not provide a reward or penalty to indicate the desirability of the resulting state. The task of the agent is to learn from the indirect and delayed reward to choose sequences of actions that produce the greatest cumulative reward.
The problem we wish to examine is finding the similarities between objects. These objects can be 3-dimensional models, colored or colorless, 2-dimensional images or the objects of any other type.
The game is intended for 2 players (2 human players or human vs. computer), each has its own 10x10 grid. At the beginning each user places 10 battleships (4 of size 1, 3 of size 2, 2 of size 3 and 1 of size 4) in his grid. Then, each user, in his turn, guesses where his rival put his battleships. The game ends when one of the users has %93sunk%94 all of his opponent%92s ships, and he is the victor. Platform Requirements: Windows CE on a Pocket PC, Palm-size PC or a Hand-Held PC Pro.
This project was to build a testing environment for path finding algorithms. This can server as a useful tool for analyzing the performance of different path finding algorithms. In this project, the focus was on artificial intelligence algorithms.
The goal of this project is to decompose a polyhedral surface into convex patches. This is a very interesting problem since there seem to be more than one possible way to complete the disassembly of a complex surface. Although there are cases in which the problem is simple and there are only few possible solutions, in most cases the result of the decomposition might be one of many. That leads to the conclusion that any algorithm that pretend to solve it, would have an non deterministic nature.
The project's primary goal is to provide the web-based tools to the Introduction to Semiconductor Devices course. By using the project, both course's staff and the students should be able to avoid the major part of the home assignments caused paper work, like submitting, checking, managing grades database, calculating statistics, etc. The other goal is to visualize one of the experiments that are studied at the course, thus providing better understanding of the material. The project consists of two loosely connected parts, which we will describe.
