Cold-startup and hot-standby reactivity accident tests conducted at the SPERT III E-core research reactor are analysed with coupled neutron-kinetic/thermal-hydraulic code system DYN3D-ATHLET. Homogenised 2-group cross sections for DYN3D thereby generated Monte Carlo neutron transport Serpent 2 in combination ENDF/B-VII.1 section library. Results terms of maximum power, energy release, compensat...

In this study, a new strategic model called Markov-based cold standby combined with components mixing (RRAP-CM-MCCS), is proposed to improve system reliability. The optimization method used here simplified swarm (SSO), in which SSO adopts multi-role resource sharing strategy provide the diverse required by RRAP-CM-MCCS. diversity lies providing every component subsystem its own failure rate as ...

An inspection policy for a standby unit is considered by taking a standby electric generator as an example. The expected cost by the time of the electric power supply failure is derived by rising renewal-type equations. We discuss an optimum checking time which minimizes the expected cost. We further obtain a checking time such that the probability that a standby generator has failed at the tim...

We propose a novel power supply circuit that can make a standby power consumption of an infrared remote (IR) controlled product completely zero. Our proposal is a hybrid power supply circuit combining the energy harvesting and conventional power supply structure. The IR controlled product employing our proposal has no pass of electric current in the standby mode. It is activated by the electrom...

In this paper, four new hybrid digital circuit design techniques, namely, hybrid multi-threshold CMOS complete stack technique, hybrid multi-threshold CMOS partial stack technique, hybrid super cutoff complete stack technique and hybrid super cutoff partial stack technique, have been proposed to reduce the subthreshold leakage power dissipation in standby modes. Techniques available in literatu...

| Low supply voltage requires the device threshold to be reduced in order to maintain performance. Due to the exponential relationship between leakage current and threshold voltage in the weak inversion region, leakage power can be no longer negligible in such circuits. In this paper we present a technique to accurately estimate leakage power by accurately modeling the leakage current in transi...

In this paper, we study reliability properties of a k-out-of-n system with single cold standby unit. We mainly focus on the case when operates in discrete time. order to describe its aging behavior consider three different mean residual life functions. By using some statistics present several monotonicity results associated these characteristics. Since calculation described quantities requires ...

Medical standby is the provision of emergency medical care and first aid for participants and/or spectators in a pre-planned event. This article describes the framework and the demographics of a medical standby at the 4(th) National Youth Camping and Motivation Program in Pasir Puteh, Kelantan from 30(th) July until the 3(rd) August 2004. The framework of the medical team is described based on ...
