Performability of a token bus network under transient fault conditions
Local area networks are representative of a growing class of distributed systems which demand more sophisticated methods and tools to evaluate system behavior in the presence of faults. In particular, since they are likely to exhibit degradable performance, the concept of performability can provide more re ned assessments of their ability to perform under fault and error conditions. This paper ...
متن کاملInvestigation of Mass Transfer Coefficient under Jetting Conditions in a Liquid-Liquid Extraction System
In this research mass transfer coefficient under jetting regime in different directions (from dispersed to continuous and continuous to dispersed phase) has been studied using an experimental setup. n-Butanol-succinic acid-water with low interfacial tension has been selected as experimental chemical system. The effects of various parameters such as jet velocity, nozzle diameter and the heig...
متن کاملFault Current Characteristics of the DFIG under Asymmetrical Fault Conditions
During non-severe fault conditions, crowbar protection is not activated and the rotor windings of a doubly-fed induction generator (DFIG) are excited by the AC/DC/AC converter. Meanwhile, under asymmetrical fault conditions, the electrical variables oscillate at twice the grid frequency in synchronous dq frame. In the engineering practice, notch filters are usually used to extract the positive ...
متن کاملStudy of Superconducting Fault Current Limiter Device in a AC Railway System
Development of the electric networks led to more interconnection in this system, therefore high level of short circuit faults flows in the networks. Many destructive damages such as instability, insulation problems and voltage mitigation can highly play unwanted influences on the system’s equipment. Using appropriate protection devices like high voltage fuses, fast switches, and such devices...
متن کاملFault-Tolerant Bus System for Airbag Sensors and Actuators
In order to satisfy the increasing safety requirements for airbag deployment systems in cars, the number of airbag actuators and sensors increases steadily. It is important to keep the complexity of the system manageable, for example by replacing the current point-to-point systems by a networked system. This paper gives an overview of such a system and discusses some of the interesting implemen...
