E ective bridging fault diagnosis requires reducing the n 2 number of bridging faults to a handful of candidates. A preliminary step can reduce the O(n) candidates to a manageable O(n) candidates by using layout information to eliminate those bridging faults that are very unlikely to be shorted together. This step removes from consideration those faults that match the fault signature but are ph...

The double impulse input is introduced as a substitute of the fling-step near-fault ground motion and a closed-form solution of the elastic–plastic response of a structure by the “critical double impulse input” is derived. Since only the free-vibration appears under such double impulse input, the energy approach plays an important role in the derivation of the closed-form solution of a complica...

AC interference from high voltage power lines can constitute an electric shock hazard and a threat to equipment integrity during both load and fault conditions. Mitigation systems are usually installed to reduce the touch voltages so that the nearby metallic utilities are safe. This paper discusses the states of the touch and step voltages for a few typical right-ofway systems under load and fa...

The WS-BPEL language has recently become a de facto standard for modeling Web-based business processes. One of its essential features is the fully programmable compensation mechanism. To understand it better, many recent works have mainly focused on formal semantic models for WS-BPEL. In this paper, we make one step forward by investigating the verification problem for business processes writte...

While sensor networks have been used in various applications because of the automatic sensing capability and ad-hoc organization of sensor nodes, the fault-prone characteristic of sensor networks has challenged the event detection and the anomaly detection which, to some extent, have neglected the importance of discriminating events and errors. Considering data uncertainty, in this article, we ...

The purpose of this paper is to propose a new histogram-based diflerential current testing procedure of active defects. This procedure contains three steps: Preanalysis, Failure Analysis, and Production Testing. The main objehtives of the Pre-analysis are to provide information on the most frequent active current defects and to help ‘setting the limits between faulty and fault-free devices: the...

Grid computing environment due to its scale and heterogeneous nature is more vulnerable to faults. To store and analyze fault and workload information, FTA Fault Trace Archive and GWA Grid Workload Archive are used. Previously researchers have analyzed FTA and GWA as separate research problems but in this research paper we have proposed a method for conducting a combined analysis of FTA and GWA...

The paper presents the application results concerning the fault detection of a dynamic process using linear system identification and model–based residual generation techniques. The first step of the considered approach consists of identifying different families of linear models for the monitored system in order to describe the dynamic behaviour of the considered process. The second step of the...

When specifying requirements for software controlling hybrid systems and conducting safety analysis, engineers experience that requirements are often known only in qualitative terms and that existing fault tree analysis techniques provide little guidance on formulating and evaluating potential failure modes. In this paper, we propose Causal Requirements Safety Analysis (CRSA) as a technique to ...

Introduction. The present study was designed to assess the effect of continuous evaluation and education in usage of standard rules in midwifery office in Shiraz. Methods. This was an interventional (quasi experimental) study. All midwifery offices (50 units) in Shiraz were evaluated by technicians from Control and Evaluation Health Office of Vice Chancellor for Clinical and Drug Affairs. In ...
