Ultra-wide band (UWB) communications transmits a wide bandwidth signal with an extremely low power spectral density. This property of UWB makes it possible to co-exist with the current narrowband communication systems operating at dedicated frequency bands. Ultra-wide band can also serve multiple users by using the Spread Spectrum (SS) technique. However, with the number of multiple users increasing, Continue reading

This project is about developing a live chatting module based on the social networking site, Orkut. We studied the working of orkut in detail and tried to extract important features in our project. Basically our project works on Continue reading
This is a simple code for telephone billing system
Attrition is a critical issue and pretty high in the industry these days. It’s the major problem which highlights in all the organizations. Though the term ‘ATTRITION’ is common, many would be at a loss to define what actually Attrition is, “Attrition is said to be the gradual reduction in the number of employees through retirement, resignation or death”.
It can also be said as ‘Employee Turnover or Employee Defection’ Whenever a well-trained and well-adapted employee leaves the organization, it creates a vacuum. So, the organization loses key skills, knowledge and Continue reading
Embedded microcomputers are used in a wide range of applications nowadays. Avionics is one of these areas and requires extra attention regarding reliability and determinism. Thus, these issues should also be born in mind in addition to performance when evaluating embedded microcomputers.
This master thesis suggests a framework for performance evaluation of two members of the PowerPC microprocessor family, namely the MPC5554 from Freescale and PPC440EPx from AMCC, and analyzes Continue reading
Variability in complex systems offering rich set of features is a serious challenge to their users in term of flexibility with many possible variants for different application contexts and maintainability. During the long period of time, much effort has been made to deal with these issues. An effort in this regard is developing and implementing different variability modeling techniques.
This thesis argues the explanation of three modeling techniques named configurable components, feature models and Continue reading
This is the Chat program with Client and Server.
It include two parts, the Server and the Chat. Both of them are netBeans 5.5 project.
The executables file exits in dist folder in both parts. Run the server part first then run the number of clients you want. Continue reading
Routers are probably the most important component of a NoC, as the performance of the whole network is driven by the routers’ performance. Cost for the whole network in terms of area will also be minimised if the router design is kept small. A new application specific processor architecture for implementing NoC routers is proposed in this master thesis, which will be called μNP (Micro- Network Processor). The aim is to offer a solution in which Continue reading
This report concerns the implementation of a simulation framework to evaluate an emerging peer-to-peer network topology scheme using 8-point hypercircles, entitled HyperCircle. This topology was proposed in order to alleviate some of the drawbacks of current P2P systems evolving in an uncontrolled manner, such as scalability issues, network overload and long search times. Continue reading
This article is about sending SMS using .NET through web service. With the help of this article, we can easily understand how to use web services in .NET, and also you will get some information about SMS, GPRS etc. This web service will help you give a notification if the service is unable to deliver. Continue reading
Microelectronics have at all times been a complicated area in space technology, the radiation environment have always created heavy restriction. This is still true today, but development of new and better devices has steadily opened up this field for new applications.
FPGAs have been used in space for some time now, but that is mostly One-Time Programmable devices. Only a few reprogrammable FPGA have flown on real space missions, but in the near future this technology can Continue reading
This paper presents an application of Adaptive Neuro-Fuzzy Inference System (ANFIS) control for DC motor speed optimized with swarm collective intelligence. Continue reading
