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...

in the conventional design and analysis methods affecting parameters (loads, materials'strength, etc) are not set as probable variables. safety factors in the current codes andstandards are usually obtained on the basis of judgment and experience, which may beimproper or uneconomical. in technical literature, a method based on nonlinear static analysisis suggested to set reliability index on st...

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...

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...

one of the most important problems in the system reliability optimization is redundancy allocation problem that has been studied in different system configurations. k-out-of-n structure is a general system configuration and offers enhanced capabilities for analyzing more design problems. hence, in this paper, the redundancy allocation problem of k-out-of-n systems is studied. in the most previo...

Leakage current minimization is an important topic for event driven applications that spend most of their times in standby mode. Power gating technique is one of the most effective ways to reduce the standby leakage current. However, when power gating technique is applied to a functional unit, there exists a delay-power tradeoff, which can be characterized with the widths of sleep transistors. ...

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 ...

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...
