In this paper, a coherent system consisting of non-identical dependent active components and equipped with non-identical dependent standby components is considered. The main object of this study is the random quantity which account the number of surviving standby components when the system is failed. We represent the distribution function of the corresponding random variable in terms of system ...

Many fielded systems use cold standby redundancy as an effective system design strategy. However, methods for analyzing the reliability of k-out-of-n cold standby systems, particularly with components having age-dependent hazard rates, are limited. In this paper, using the concepts of counting processes, we propose an efficient method to evaluate the reliability of k-out-of-n cold standby syste...

Automated home applications are to ease the use of technology and devices around the house. Most of the electronic devices, like shutters or entertainment products (Hifi, TV and even WiFi), are constantly in a standby mode, where they consume a considerable amount of energy. The standby mode is necessary to react to commands triggered by the user, but the time the device spends in a standby mod...

This investigation deals with the transient analysis of the machine repair system consisting of M-operating units operating under the care of single repairman. To improve the system reliability/availability, Y warm standby and S cold standby units are provided to replace the failed units. In case when all spares are being used, the failure of units occurs in degraded fashion. In such situation ...

In this paper, a novel single-port five-transistor (5T) Static Random Access Memory (SRAM) cell and associated read/write assist are proposed. Amongst them, a word line suppression circuit is to provide a voltage of the respective connected word line to be lower than or equal to the power supply voltage VDD, so that the read/write-ability of the cell can be improved, and the half-selected cells...

In this paper we study the multiple systems of repair problem and present N-system with one working and the other systems are in repair, in standby or waiting repair. When the working system can fails it goes to repair and instantaneously a standby system becomes the working one. Standby system stands to system when the original system is on under repair. The systems are repair following the ar...

In this paper, a new single-port five-transistor (5T) Static Random Access Memory (SRAM) cell with integrated read/write assist is proposed. Amongst the assist circuitry, a voltage control circuit is coupled to the sources corresponding to driver transistors of each row memory cells. This configuration is aimed to control the source voltages of driver transistors under different operating modes...

This paper presents a multiprocessor control system for standby power supply applications. The system is responsible to initiate a standby generator in order to provide power supply to a target load in case of mains supply failure. Typical applications are standby generators at bank offices, hospital buildings, airport premises and mobile telephony base stations. The system possesses a great co...

I am concerned about the implications of the Editorial by Drs. Lown and Axelrod which appeared in the October 1972 issue of Circulation. Although the authors rightfully point out the numerous technical problems still to be overcome in the development of such defibrillators, their conclusions in the last three paragraphs indicate a heavy bias in favor of "practical research." Although Dr. Lown h...
