Explain the obstacles and advantages of the competing technologies J2EE and Microsoft's .NET with respect to teaching andlearning in a university environment J2EE and Microsoft .Net are two competing technologiesthat aim to achieve the same thing. That aim is to simplify development of webapplications by providing a standard set of components and services that can beaccessed regardless of operating system. This enables focus to given to thebusiness logic and development of it. The benefit of...
CVE stands for Common Vulnerabilities and Exposures.CVE Vulnerablities and exposures CVE is a dictionary of common names such as this CVE Identifiers for publicly known information security vulnerabilities, while its common configuration enumeration provides identifier for security configuration exposures and vulnerability issues (CVE, 2010). CVE common identifier facilitates the exchange of data across separate network security database, tools and provide the bases for assessing the...
Crthogonal Frequency Division Multiplexing is an effective modulation scheme to improve the performance of a communication system over wireless multipath fading channels. The aim of this paper is to analyze the effect of phase noise using different phase noise models due to local oscillators, and also propose the compensation technique for each model over fading channels. Also this paper analyzed the effect of phase noise over different channel conditions. The effect of phase noise in OFDM is...
Software Engineering Dissertation. Project Title: A web-based student monitoring system I need to write a Project Definition Document (1000 words). Project Title: A web-based student monitoring system Background of the project: I need a system by which personal tutors can monitor the attendance of their first-year students, to detect those who are not keeping up as early as possible. A partial system exists: it offers some queries, but is too inflexible for adding and modifying data. The...
In present, there is an increase in the ratio of applications based on heterogeneous multimedia traffic with new enhancements and conditions. The network traffic with different applications in accordance with the requirements in terms of delay, jitter, loss, throughput, interaction and reliability features. In the past, wireless local area networks with IEEE 802.11 standard did not support QoS management especially in case of voice, voice and delay sensitive application but due to the increase...
When developing a web site many things need to be considered for the elderly, the physically impaired and especially the disabled. Also to increase the accessibility of your web site a developer must take in consideration the user, the many ways the user interacts with the essentials components and how people with disabilities use the web. In order to completely understand the task at hand one must take in consideration these three major points - Firstly, web accessibility basically means that...
Abstract- This paper proposes a fully digital high performance variable speed drive of induction motor implementing based on a single chip DSP motor controller. Some important models and features of the Field Oriented control are analyzed in detail and the implementing flowchart is given. The proposed speed control algorithm programming in C is realized by the TMS320LF2407 DSP offering a fast current response. Simulation results show that the performance of Field Oriented control of induction...

At the very beginning of this computer era, most of the Computers were used all alone to do the odd traditional day to day activity, and were used as ordinary tools where processing was done mainly on each and every single computer as resources were isolated and not distributed or not even centralized. paragraph \But then the computer networks and Internet were introduced to the computer world. And resources came more and more distributed and easy to access as the era evolves. So the computers...
Security is an aspect which is very important in current scenario especially when there exists concerns over private or corporate of a firm. To secure a network of connected computers, experts need to work on specialized devices like firewalls and routers. In some case there exist wireless accesses points, in such a scenario we have the requirement that the data traffic along the network needs to follow an encryption algorithm which could be used for encrypting the data and any new station must...
