This paper deals with a stochastic model for a two-unit hot standby combined hardware-software system in which one unit is operative and the other is hot standby. The operative unit may have hardware or software failures and goes to repair. This leads to degradation of the system and then hot standby unit is under operation. Further on hardware or software failures of the hot standby unit the s...

Apart from important but particular cases, such as state-dependent exponential distributions, for example, [1, 4] or an arbitrary repair time distribution [12], the reliability analysis of multiple cold standby systems is far from complete. We present a general reliability analysis of a basic multiple cold standby system attended by a single repairman, henceforth called a K-system. The K-system...

Energy conservation is an important global issue. The home is the third largest energy consumer, and 10% of the home energy use is standby power of home appliances. The proliferation of home networks increases the standby power. The conventional technologies for low networked standby power such as WoL require continuous AC power, as much as 0.5 watts, to monitor wake-up signals. A large portion...

This paper we proposed advanced burst mode control technique to reduce the standby power consumption of the switch mode power supply (SMPS). To reduce the standby power consumption, most of the converter use burst mode or skip mode control technique. However Conventional standby mode control techniques have some problems such as audible noise and poor regulation. In proposed techniques, basical...

Protection cycles is a well know dependability measure and commonly applied in SDH networks with ring topologies. Applying protection cycles (known as p-cycles) in meshed network has recently been shown to provide good protection against failures in both network links and nodes. Upcoming optical burst and packet switched networks will require node protection. Increasing the density of meshing i...

CMOS is furthermore the most widespread technology for digital designs as no feasible alternative is in sight to date and in the near future. The fundamental causes for this supremacy so far are the capability for miniaturization as well as the reliability and robustness of CMOS. Against the background of nanotechnology though, reliability concerns are arising with an alarming pace. The consequ...

Hereafter, we propose a novel approach that couples HW/SW codesign with redundancy techniques to implement speech recognition systems (SRS). Due to the specific characteristics of digital signal processing (DSP) algorithms, these systems deserve special attention when partitioning the HW and SW parts. Also, in many applications like voice-oriented bank transactions or security systems, the need...
