Virtual machine technology has been successfully applied for the construction of fault-tolerant computing systems. For example, vmware Fault Tolerance and Xen Remus support transparent failover of VMs running on different physical machines in a local area network. However, high availability alone is in many application domains not sufficient. Especially in the context of Cyber-Physical Systems,...

A fault-tolerant control scheme (FTCS) was developed for a novel mechatronic track switch the first time. The FTCS and tested on simulation model of system, before being applied to an experimental actuation system in laboratory. Both results show that this works as expected allows continue operating desired under sensor failure, preventing damage switch.

Research Highlights: This study was carried out to diagnose the forest ecosystem damaged by air pollution and then develop a restoration plan be used in future. The prepared combining diagnostic assessment for reference information obtained from conservation reserve with an intact ecosystem. includes method amelioration of acidified soil plant species introduced vegetation depending on degree d...

This paper discusses the modeling and analysis of three major fault-tolerant software system architec-tures: DRB (Distributed Recovery Blocks), NVP (N-Version Programming) and NSCP (N Self-Checking Programming). In the system-level reliability modeling domain, fault tree analysis techniques and Markov reward modeling techniques are combined to incorporate transient and permanent hardware faults...

drought stress, especially drought at terminal stages, plays an important role in reduction of yield in field crops such as common beans. 50 genotypes of common bean including 3 control genotypes (dehghan, bahman and naz) were used to evaluate and identify the tolerant genotypes. this experiment were performed in a randomized complete block design (rcbd) with three replications under two condit...
