This newly proposed solution to the minimal test generation problem of combinational circuits is based on (1) identifying independent faults, (2) generating tests for them, and (3) minimizing the tests. The third part, test minimization, is accomplished by an already known solution using integer linear programming (ILP). Using the theory of primal-dual linear programs, we model the independent ...

Network reliability is very important for the next generation of optical networks. In this paper, a highly reliable protection mechanism, which integrates approaches and microwave protection, proposed metro-access networks based on wavelength division multiplexing (WDM) technique. By designing scheme convergence wireless access cooperating with designed remote nodes (RNs), not only can both wir...

This paper presents an algorithm for adaptive determination of the dead timeduring transient arcing faults and blocking automatic reclosing during permanent faults onoverhead transmission lines. The discrimination between transient and permanent faults ismade by the zero sequence voltage measured at the relay point. If the fault is recognised asan arcing one, then the third harmonic of the zero...

determining the promising area for ore deposits is one of the most important steps of prospecting in regional scales. there are many different methods for identifying these areas including geochemical and geophysical methods, remote sensing and sophisticated statistical methods. based on the theory of spatial relations between the dispersion pattern of ore deposits and metallogenic provinces, m...

The transient stability of traditional power systems is concerned with the ability generators to stay synchronized positive-sequence voltage network, whether for symmetrical or asymmetrical faults. In contrast, both positive- and negative-sequence synchronizations should be concern inverter-based generation (IBG) under This because latest grid codes stipulate that IBG inject dual-sequence curre...

the oudna field part of the offshore northeastern tunisia, straddles between two structural domains, the tunisian atlas to the north and the pelagian sea to the south. the study of this field has confirmed adequate petroleum system in fahdene formations (albian-cenomanian) and birsa (serravallian) resulting from the combination of several sedimentary, tectonic and thermal factors. to do this, w...

Aiming at single mode of Underpan generator power supply, and the feature being not meet regular work system under special working conditions, engine fuel exhaustion, unexpected faults, Design Dual Mode Power Supply Distribution Circuit With Detection And Control Functions which includes Battery power, distribution module, anti-diode, detection underpan on-off control anti-loss module was propo...

Knowledge-driven and data-driven methods are the two representative categories of intelligent technologies used in fault diagnosis nuclear power plants. have advantages interpretability robustness, while better performance ease modeling inference efficiency. Given complementarity methods, a combination them is worthwhile investigation. In this work, we introduce new techniques based on Bayesian...
