Modeling and analyzing the dependability of software systems is a key activity in the development of embedded systems. An important factor of dependability is availability. Current modeling methods that support availability modeling are not based on a rigorous modeling theory. Therefore, when the behavior of the system influences the availability, as it is the case for fault-tolerant systems, the...
Reliability concepts, models and methods have been developed in different fields and applied to a variety of engineering cases from component, system to process. Besides the great amount of successive applications, challenges are everywhere including the understanding to the role of random load environment, especially its uncertainty in reliability estimation and experiment, the mechanism to produce...
The efficient development of a highly reliable system, such as a new crew launch vehicle, cannot afford to ignore the lessons of history. A number of interesting studies of launch vehicle failures provide very valuable, albeit qualitative “lessons learned” on measures that a risk-informed program should take. If schedule and funds were unlimited, a very intensive and exhaustive test program would...
The following topics are dealt with: planar SOI devices; SOI memories; SOI photonics, MEMS, sensors and circuits; materials and 3D technologies; multi-gate SOI devices; SOI radiation effects and RF applications; device characterization, reliability, and modeling.
In this paper we discuss performance results of a novel real-time closed-loop power amplifier (PA) linearization technique that has originally been proposed by Ahmed and Li. The novel approach performs on-the-fly prediction and measurement of the PA AM/AM and AM/PM non-linearity, stores such non-linear characteristics and calculates their inverse functions in order to pre-distort the base-band amplitude...
