Intelligent instruction of fault diagnosis, or troubleshooting, tasks requires the capability to automatically infer the significance of particular test outcomes observed by the learner in a practice environment. This single process is central to virtually every aspect of intelligent instruction in this domain, ranging from evaluating learner proficiency to recommending an effective testing str...

This paper presents the results of a n empirical study of software e r r o r detection using self checks and N-version voting. A total of 24 graduate students in computer science a t the University of Virginia and the University of California, Irvine, were hired a s programmers. Working independently, each first prepared a set of self checks using just the requirements specification of a n aero...

This paper describes a new methodology to inject transient and permanent faults in digital systems. For this purpose, the simulation based fault injector VERIFY (VHDL-based Evaluation of Reliability by Injecting Faults efficientlY) has been developed, which allows fault injection at several abstraction levels of a digital system. The combined approach of injection and analysis of the results en...

Inside digital systems, errors are a result of temporary and permanent faults, these last requiring less redundancy usually to be detected. Beyond traditional techniques as duplex with comparison or Self-Checking designs, one recently presented, and relevant in this context, is named Concurrent Scan Test (CST) [1]. CST enhances the IEEE 1149.1 (BST) infrastructure to detect faults concurrently,...

6 [1] We examine the work energy budget of actively deforming fault systems in order to 7 develop a means of examining the systemic behavior of complex fault networks. Work 8 done in the deformation of a faulted area consists of five components: (1) work done 9 against gravity in uplift of topography (Wgrav); (2) internal energy of the strained host rock 10 (Wint); (3) work done resisting frict...

This article puts forward a new algorithm based on Kullback–Leibler divergence (KLD) for discriminating inrush and internal fault currents in power transformers. Specifically, the main idea of this is to utilize current signal discrepancy distribution with ideal waveforms. To such an aim, proposed index reproduces differential signal. Utilizing fast modified least squares technique, generated. ...
