This paper presents a new decentralised fault detection and mitigation system for excitation control systems used in synchronous generators in power grids. The system detects and diagnoses faults in the basic components of the excitation control systems with high accuracy and in almost real time using fuzzy set theory. Once a fault is diagnosed, a mitigation action follows, where the signal out of...
An approach for fault diagnosis and restoration in the excitation systems of multi-machine power systems is presented in this paper. The approach is capable of detecting and locating faults in any exciter anywhere in the system with high accuracy using simple fuzzy logic. The use of logic only implies that faults can be detected in near real time. Once the fault is detected, the excitation is immediately...
This paper proposes a model for call admission control in the next generation wireless networks. It presents a prioritized call admission procedure using the combination of buffer and guard channel schemes applicable to the heterogeneous networks in general and wireless overlay network (WON) in particular call admission priority is given to the real time calls over the non-real time calls which are...
Development of non-invasive methods for quantitating the bone mass is important in the diagnosis and treatment of many skeletal diseases, particularly for osteoporosis. As standard roentgenographic methods can not detect early osteoporosis, presently quantitative computed tomography (QCT), and single, and dual photon absorptiometry (SPA and DPA) are being used to monitor the skeletal health of elderly...
