Two contrasting views of the active deformation of Asia dominate the debate about how continents deform: (i) The deformation is primarily localized on major faults separating crustal blocks or (ii) deformation is distributed throughout the continental lithosphere. In the first model, western Tibet is being extruded eastward between the major faults bounding the region. Surface displacement meas...

A robust testing method for detecting circuit faults within two-dimensional Cellular Neural Network (CNN) arrays is presented. The functional tests consist of a sequence of input vectors that toggle all internal nodes of the conceptual CNN model and propagate the result to the output pins. The resultant output vectors reveal nodes that exhibit opened, shorted, or stuck-at faults. The generated ...

This paper presents an Internal Model Control based structure to realise fault tolerance towards sensor faults. The proposed design implicitly embeds fault detection and controller elements requirements with considerations to stability and robustness towards uncertainties besides multiple faults environment. The performance of the proposed controller is demonstrated via multi input multi output...

A methodology is proposed to diagnose faults from a detection system that allows to express uncertainty with intervals in parameters and measurements. A fault is detected by comparing current measurements with computed external and internal approximations of behavior. The results are applied to diagnose faults. A qualitative data set is obtained in order to create fault rules. A fault library i...

An algorithm for diagnosing two node bridging faults in static CMOS combinational circuits(full scan circuits) is presented. This algorithm uses results from I DDQ testing. The bridging faults considered can be between nodes that are outputs of a gate or internal nodes of a gates. Experimental results on all the ISCAS89 circuits show that I DDQ measurement based diagnosis using a small number o...

Effective discrimination between transient and permanent faults is a very important practical problem in (dependable) system design. A count-andthreshold mechanism named α-count, designed to discriminate between transient faults and intermittent faults in computing systems, is presented in an enhanced embodiment. It retains enough simplicity to allow exhaustive analysability through simple mode...

internal turn-turn faults (ttf) are the most common failures in power transformers, which could seriously reduce their life expectancy. although common protection schemes such as current-baseddifferential protection are able to detect some of the internal faults, some other minor ones (such as ttfs andshort circuit near the neutral point) cannot be detected by such schemes. likewise, these rela...

The internal faults of transformer can be identified by various techniques. The proposed technique is by the analysis of no-load current and harmonic contents present in it. The no-load current of transformer is non-sinusoidal for sinusoidal input voltage. And hence it contains harmonics in healthy condition of transformer. But if transformer has any internal fault then the no-load current magn...

Grid faults are common in power systems and can have a severe impact on the operation of the converters in the system. In this paper, the operation of a Modular Multilevel Converter (MMC)-based Static Synchronous Compensators (STATCOM) is investigated during grid faults. The study focuses on the challenging internal control of the converter to allow the independent control of the energy levels ...

A medical system is complicated because it has many sub-modules and is connected with many kinds of other systems. Because software faults tend to occur in interoperation among modules, a safety-critical medical system should be tested strictly in terms of integration. At integration testing phase, there are too many execution path of software to test, that makes testing difficult. To deal with...
