Two different system configurations with warm standby components, standby switching failures, two types of failures "common cause failure and hardware failure" and general repair are compared based on the availability. The time-tofailure for each of the primary and warm standby components are assumed to follow the exponential distribution. Laplace transforms of state probability equations are d...

In this paper, we analyze the spectra and stability of a system consisting of a working unit and repair unit, in which the working unit consists of one main unit and one standby unit, while the standby unit may deteriorate in its standby mode. Firstly, we formulate the problem into a suitable Banach space. And then we carry out a detailed spectral analysis of the system operator. Based on the s...

An ultra-low-leakage power-rail ESD clamp circuit, composed of the SCR device and new ESD detection circuit, has been proposed with consideration of gate current to reduce the standby leakage current. By controlling the gate current of the devices in the ESD detection circuit under a specified bias condition, the whole power-rail ESD clamp circuit can achieve an ultra-low standby leakage curren...

This paper presents a fully synthesizable low power interconnect bus for millimeter-scale wireless sensor nodes. A segmented ring bus topology minimizes the required chip real estate with low input/output pad count for ultra-small form factors. By avoiding the conventional open drain-based solution, the bus can be fully synthesizable. Low power is achieved by obviating a need for local oscillat...

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...

Reliability theory bases on the concept of boolean components, i.e. of up, operating or down, failed components. But often such assumption is not adequate for modeling specific behaviors of components, units, subsystems and systems. It cannot catch, for example, different operating conditions of components due to dependencies on other components or environment variations. Aim of this paper is t...
