This paper presents a new fault tolerance scheme suitable for humanoid robot applications. In the future, various tasks ranging from daily chores to safety-related tasks will be carried out by individual humanoid robots. If the importance of the tasks is different, the required dependability will vary accordingly. Therefore, for mobile humanoid robots operating under power constraints, fault to...

In this paper, we propose a five-transistor (5T) static random access memory (SRAM) that can be read and written reliably with the assistance of read/write circuits. The read/write circuits include a voltage control circuit, a pre-charging circuit and a standby start-up circuit. The voltage control circuit is connected to the sources corresponding to driver transistors of each row memory cells....

Cascade reliability model is a special type of Stress Strength model. The n Cascade system is a h ierarch ical standby redundancy system, where the standby component taking the place of failed component with decreased value of stress and independently distributed strength. This paper deals with the generalized exponential distribution with cascade system.

The Redundancy Allocation Problem (RAP) is well-known in the field of reliability optimization. In this paper, RAP investigated assuming that distribution time to failure components has form an Erlang with a time-dependent rate parameter and considering choice redundancy for each subsystem can be none, active, standby or mixed. A genetic algorithm used solve problem optimal allocation. To analy...

Some theoretical evaluation methods of mean time to failure (MTTF) in 2-component standby redundant system with priority have been suggested under the prerequisite that the probability distributions of failure and repair times in each component are respectively specified by the explicit functions. However, this prerequisite might be considerably strict in practical scenes. If we cannot identify...

New, small-scale electric generation technologies permit utility customers to generate some of their own electric power and to utilize waste heat for space heating and other applications at the building site. This combined heat and power (CHP) characteristic can provide significant energy-cost savings. However, most current US utility regulations leave CHP standby rate specification largely to ...

We present a new approach for the estimation and optimization of standby power dissipation in large MOS digital circuits. We first introduce a new approach for accurate and efficient calculation of the average standby or leakage current in large digital circuits by introducing the concepts of “dominant leakage states” and the use of state probabilities. Combined with graph reduction techniques ...
