We analyse the reliability (survival function) of a duplex system characterized by hot standby and sustained an auxiliary unit in cold standby. The entire is attended two heterogeneous repairmen. Our methodology based on theory sectionally holomorphic functions combined with notion dual transforms. Finally, we also study total occupational time repairman responsible for repair failed priority d...

Pumping systems are an integral part of water desalination plants, their effective functioning is vital for the operation of a plant. In this research work, the reliability and availability of pressurized pumps in a reverse osmosis desalination plant are studied with the objective of finding configurations that provides optimal performance. Six configurations of a series system with different n...

In this paper, a new single-port five-transistor (5T) Static Random Access Memory (SRAM) cell and associated read/write assist circuitries is proposed. Amongst them, a voltage level conversion circuit is to provide a voltage of the respective connected word line to be lower than or equal to a power supply voltage VDD such that the read/write-ability of the cell can be improved. Furthermore, a v...

The present study deals with a robot safety system composed of standby robot units and inbuilt safety unit. When the main operative unit fails, it is replaced by the standby robot unit available in the system. The concept of reboot delay is also incorporated in this study according to which the robot unit is rebooted if it is not successfully recovered. The recovery and reboot times of failed u...

The redundancy allocation problem (RAP) is one of the most commonly used approaches for improving reliability systems. present study investigates recent variant RAP, namely, RAP with heterogeneous components under mixed strategy. An exact branch-and-price (BP) algorithm proposed that solves in less than CPU second all benchmark instances reported literature. not only first a strategy but also a...

A current sensing device, namely Hall Effect MOSFET (HEMOS) is proposed. It is experimentally shown that the HEMOS enables a non-contacting, and non-disturbing current measurement, which can be used for IDDQ testing of internal circuit blocks. The HEMOS can be manufactured and integrated in a VLSI with the conventional CMOS process. The HEMOS is also helpful to establish the low standby current...

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...
