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...

By using the Markov process, system state transitions can be modelled to predict the system availability in many realistic applications, wherein all components of the system cannot be treated as identical because of their failure and repair characteristics. In this paper, efforts have been made to examine the availability characteristics for three different configurations with warm standby, swi...

Cluster systems, using commercially available personal computers connected in a loosely coupled fashion can provide high levels of availability. To improve the availability of personal computer-based Active/Standby cluster systems, we have conducted a study of software rejuvenation that follows a proactive fault-tolerant approach to handle software-origin system failure. In this paper, we map s...
