Faculty of Engineering, University of Cairo, Egypt



Abstract:

The most commonly used controller for the speed control of dc motor drives is (P-I) controller. In spite of the major features of the (P-I) controller, it has some disadvantages such as: the high starting overshoot in speed, the sensitivity to controller gains and the sluggish response due to sudden change ....etc

Real-Time Positioning Technology Fleet management system is a rapid growing industry. This system helps institutions to manage vehicle fleet efficiently and effectively through smart allocation of resources. In this project, an intelligent fleet management system which incorporates the power of concurrent Global Positioning System (GPS) and Global System for Mobile Communications (GSM) real-time positioning, front-end intelligent and web-based management software is proposed. In contrast to systems which depend solely on GPS positioning, the pr ....etc

Hi to all

I am doing project on Estimation of Defects Based on Defect Decay Model
I completed all modules except the 3rd Module that is Error Estimation module, i don't know how to proceed for that module.

Can any one help to complete that task???????

Waiting for quick reply

Thanking you. ....etc

Estimation of Defects Based on
Defect Decay Model: ED3M
Abstract:

An accurate prediction of the number of defects in a software product during system testing contributes not only to the management of the system testing process but also to the estimation of the product s required maintenance. Here, a new approach, called Estimation of Defects based on Defect Decay Model (ED3M) is presented that computes an estimate the defects in an ongoing testing process. ED3M is based on estimation theory. Unlike many existing approaches, the techniqu ....etc

This work proposes a new, software-based, defect detection and diagnosis technique. We introduce a novel set of instructions, called Access-Control Extensions (ACE), that can access and control the microprocessor s internal state. Special firmware periodically suspends microprocessor execution and uses the ACE instructions to run directed tests on the hardware. When a hardware defect is present, these tests can diagnose and locate it, and then activate system repair through resource reconfiguration. The software nature of our framework makes i ....etc

Estimation of Defects Based on Defect Decay Model: ED3M
An accurate prediction of the number of defects in a software product during system testing can contribute a great deal to the system's testing process as well as the estimation of the project's required maintenance. Estimation of Defects based on Defect Decay Model (ED3M) is presented in this article. This procedure is used for the purpose of predicting the estimate of the total number of defects that can arise in an ongoing test process. This method is based on the estimation the ....etc
