Original scientific paper Mining near the fault structure can easily lead to the fault activity and induce serious geological disasters, posing a serious threat to coal mine safety production. To reveal the surrounding rock activity characteristics induced by near-fault mining, taking Qixing Coal Mine in China as the engineering background, the contrastive analysis of the microseismic events in...

In the recent years the wind turbine industry has focused on optimizing the cost of energy. One of the important factors in this is to increase reliability of the wind turbines. Advanced fault detection, isolation and accommodation are important tools in this process. Clearly most faults are dealt with best at a wind turbine control level. However, some faults are better dealt with at the wind ...

Preliminary communication There are currently no appropriate methods to find CNC system software defects and eliminate hidden dangers. In order to improve CNC system reliability, the architecture expansion-based fault location method in CNC system software was proposed in this paper. The failure of CNC system software was 619 analysed, the expansion method of CNC system software architecture wa...

of the Dissertation Fault Detection and Diagnosis for A Multi-Actuator Pneumatic System by Kunbo Zhang Doctor of Philosophy in Mechanical Engineering Stony Brook University 2011 In pneumatic actuating systems, various kinds of faults are key factors in degrading system performance and increasing air consumption. It is therefore valuable to monitor pneumatic systems and implement predictive main...

Model-based fault detection and isolation (FDI) is an approach with increasing attention in the academic and industrial fields, due to economical and safety related matters. In FDI, the discrepancies between system outputs and model outputs are called residuals, and are used to detect and isolate faults. This paper proposes a model-based architecture for fault detection and isolation based on f...

superconductor fault current limiter (sfcl) is an effective device to suppress high fault currents. this paper presents a comparative study of resistive and inductive fault current limiters from transient stability point of view.  appropriate location and type of the limiters in a hv substation is selected by a qualitative approach based on the equal area criterion. study system is simulated by...

Most implementations of the widely-used RSA cryptosystem rely on Chinese remaindering (CRT) as this greatly improves the performances in both running times and memory requirements. Unfortunately, CRT-based implementations are also known to be more sensitive to fault attacks: a single fault in an RSA exponentiation may reveal the secret prime factors trough a GCD computation, that is, a total br...

This paper presents accurate fault models, an accurate fault simulation technique, and a new fault coverage metric for resistive bridging faults in gate level combinational circuits at nominal and reduced power supply voltages. We demonstrate that some faults have unusual behavior, which has been observed in practice. On the ISCAS85 benchmark circuits we show that a zero-ohm bridge fault model ...

The growing demand for higher operational effectiveness and reliability in industrial processes has resulted in a huge attention in fault detection techniques. Researcher and practitioners are remains concerned with correct prediction when developing systems. On the other hand the most popular research area is software fault or fault prediction. Software fault prediction has both security and f...

This paper presents a novel fault location method for series compensated transmission lines. It is established based on synchronized voltages sampling and Thevenin impedance from both ends of series compensated transmission line. The method is based on the use of phasor measurement units (PMU) technology which is aimed to be independent of current measurements, fault type, fault resistance, fau...
