Controller Area Network operational characteristic supports periodic, sporadic and event based task behavior of distributed embedded system for industrial applications. CAN connect distributed Electronics Control Units (ECU) serially in the network and share measured data of different parameters and control information from the different places. System reliability and redundancy can be affected...

In a shared memory multiprocessor system, two or more processors may simultaneously request the use of a shared resource. Therefore, an arbitration circuit is essential to resolve the contention among the competing processors and allocate the resource to the appropriate requesting processor (according to an arbitration protocol). A number of arbiter desians for multiDrocessor systems have been ...

The advent of Video On Demand (VOD) technology has seen the development of specialized high performance, high reliability computer systems. These systems must be able maintain the constant bandwidth required by video while guaranteeing fault resiliency. The SeaChange digital video cluster incorporates several different bus and fabric technologies to deliver high performance and data reliability...

bus accident is a major health problem for bus drivers.  to identify the risk factors involved in bus accidents and to design a model showing the relation between the risk factors and bus driver’s health status, 219 bus drivers who worked for travel agencies in two areas of west and central iran were enrolled into this study.  we used a questionnaire to gather information regarding both the bus...

Security and reliability of electrical power supply has become indispensable to modern society, the system operator is challenged manage increasingly complex in a manner that ensures expected security operation. In this context, Volt/VAR optimization (VVO) plays key role efficient delivery through transmission system, contributing significantly security, reliability, quality economy This articl...

Transmission network expansion planning (TNEP) faces critical challenges to not only keep reliability criteria, but also effectively reduce huge investment cost. Recently, TNEP has been modeled by probabilistic method for the security and reliability criteria, including power market concepts as well. This paper presents a reliable and economic approach for solving TNEP problem through a simple ...

THE ROLE OF THE COMMUNICATIONS BUS is fundamental in distributed real-time control systems. Such systems are increasingly used for critical functions in avionics, automotive and factory control situations, placing increased dependability and real-time constraints on the bus. Environmental influences such as electromagnetic interference are hard to avoid so a “flexible” bus may be able to provid...

Abstract As a rocket engine for thrust vector control system of high reliability and redundancy, precision, the requirements lightweight, servo test can quickly certain level fast data processing location, transient, frequency characteristic indexes, motor using GLINK as bus. Moreover, first is an all-in-one machine with four drives controls, so required to have ability actuators simultaneously...

The emerging communication applications such as IPTV, VoIP, infotainment, interactive games, and Internet access might dictate very high reliability and availability in future fiber access networks. We present an easy-to-use software tool, called NetExpert, designed to simplify the network planning, design and optimization processes and save valuable time preparing network configurations that p...

Bus systems in the United States are unattractive to many potential riders because of their lack of efficiency, especially with regard to travel time. One of the reasons services are not more efficient has to do with the spacing of bus stops. After using a nearest facility algorithm with an 800 m walking distance threshold to identify eligible bus stops in the current bus system in the city of ...
