Distributed control systems in power plants are the latest trends to optimize and control performance. Reliability prediction of input-output components of distributed control systems have a key role to play in the power plant scenario. Triple modular redundancy is a means of increasing reliability of systems. Triple modular redundancy of three modules each containing m cards is studied in this...

Simple series systems of identical components with spare parts are considered. It is shown that the cumulative distribution function of a system failure time tends to a step function as the number of components increases and resources can be shared. An example of ‘continuous resources’ is also described. The time-sharing strategy for standby systems is investigated. It is proved that an optimal...

Abstract Standby mode is the in which space advanced technology demonstration satellite (SATech) stays for a long time when all payloads are not working. This ensures energy supply of on one hand and long-term effectiveness satellite’s star tracker quaternion other hand. Firstly, target guidance law standby designed. Secondly, installation position designed according to characteristics law. Thi...

In this paper, we model a cold standby repairable system with one repairman. Suppose that the system consists of two dissimilar components and one repairman, in which component 1 is the major working unit and component 2 is the cold stand-by unit, component 1 has priority in use and repair; then the repairman takes a single vacation. Under these assumptions , we derive a model of partial differ...

In this paper we concern ourselves with the problem of minimizing the standby power consumption in some of the house hold appliances. Here we propose a remote controlled device through which we could reduce the amount of standby power consumed by the electrical appliances connected to it. This device provides an option of controlling each of the appliances connected to it individually or as a w...

An electric pacemaker may, under certain circumstances, compete with an intrinsic cardiac rhythm and share control of the heart. Should an electric stimulus fall in the vulnerable phase of the ventricular cycle, potentially dangerous arrhythmias may be provoked (Sowton, 1965; Siddons and Sowton, 1967; Bilitch, Cosby, and Cafferky, 1967). " Ventricular-programmed " or " demand " pacemakers, whic...
