Due to their increasing complexity, today’s SoC (System on Chip) systems are subject to a variety of faults (e.g., soft errors, component crash, etc.), thereby making fault tolerance a highly important property of such systems. However, designing fault tolerance is a complex task in part due to the large scale of integration of SoC systems and different levels of abstraction provided by modern ...

High-performance distributed computing across wide-area networks has become an active topic of research [1][3][4][11]. Metasystem and grid software infrastructure projects, most notably, Legion [4] and Globus [3], have emerged to support this new computational paradigm. Achieving large-scale distributed computing in a seamless manner introduces a number of difficult problems. This paper examine...

Line-commutated converter-voltage source converter (LCC-VSC) power transmission technology does not have the problem of communication failure very usually. It therefore can support long-distance, long-capacity electric energy. However, factors such as topology, control strategy, and short-circuit capacities make traditional protection principles fully applicable to LCC-VSC hybrid systems. To en...

In this paper, we address the state/fault estimation and observer-based control issues for switched systems with sensor faults. The main objective is to estimate faults compensate their effects on system state estimation, then stabilize by estimated feedback. Applying mode-dependent average dwell time (MDADT) concept Lyapunov stability theory, a new separation principle developed, which allows ...

We study the possibility of constructing decision trees with evolutionary algorithms in order to increase their predictive accuracy. We present a self-adapting evolutionary algorithm for the induction of decision trees and describe the principle of decision making based on multiple evolutionary induced decision trees – decision forest. The developed model is used as a fault predictive approach ...

Reformulated principle for designing the observer-based regonfiguration control in the continuos-time linear MIMO systems is treated in this paper. Based on the linear matrix inequalities the problem addressed can be indicated as the approach giving the sufficient conditions to design the stable estimator and controller with the on-line based fault estimation and accommodation support. The syst...

Abstract The radio altimeter system is an important part of the aircraft navigation system, failure will directly affect flight safety. Therefore, to ensure safe aircraft, a fault diagnosis method based on trees and Bayesian networks was proposed in this paper. Firstly, starting from composition working principle, taking typical ‘loss altitude displays’ as example, were set up comprehensively a...

The NNW-trending Dena Fault, with 140 km length, cuts the major structures of Zagros Fold-Thrust Belt in Borujen region. The fault has divided the region in two zones, in which different structural, andmorphological features as well assedimentation and seismtectonic characteristics have developed. This study presents a new interpretation for the kinematics of Dena Fault based on field evidence....

Counting networks were proposed by Aspnes, Herlihy and Shavit 4] as a technique for solving multiprocessor coordination problems. We describe a method for tolerating an arbitrary number of faults in counting networks. In our fault model, the following errors can occur dynamically in the counting network data structure: 1) a balancer's state is spuriously altered, 2) a balancer's state can no lo...

Genetic algorithms, as kind of fast, simply and highly fault-tolerant algorithms for near-field microwave detection of breast cancer; are useful processing method. For the image has not been dealt with high demands, which can quickly detect the interested area, and by bypassing the nonline Inversion of the problem brought about difficulties. The article mechanism to the imaging reflecting from ...
