In a testing environment, where an IUT communicates with multiple entities, a tester may have diiering degrees of controllability on the interactions between these entities and the IUT: directly controllable, semicontrollable, or uncontrollable. In this paper, a graph conversion algorithm is introduced that ooers the testability of both the directly and semicontrollable inputs, while avoiding r...

uniaxial compressive strength (ucs) and internal friction coefficient (µ) are the most important strength parameters of rock. they could be determined either by laboratory tests or from empirical correlations. the laboratory analysis sometimes is not possible for many reasons. on the other hand, due to changes in rock compositions and properties, none of the correlations could be applied as an ...

An essential step toward the development of an intelligent substation is to provide self-diagnosing capability at the equipment level. Transformers, circuit breakers and other substation equipment should be enabled to detect their potential failures and make life expectancy prediction without human interference. This paper focuses on the development of an on-line equipment diagnostics using art...

This paper will propose a cascade of minimum description length criterion with entropy approach along with artificial neural network (ANN) as an optimal feature extraction and selection tool for a wavelet packet transform based transformer differential protection. The proposed protection method provides a reliable and computationally efficient tool for distinguishing between internal faults and...

The IEC 61850-advanced smart transformer shows an improved performance in monitoring, controlling, and protecting the devices and equipment in smart substation. However, the heterogeneity, feasibility and network control problems have limited smart transformers in network performance. To address these issues, a software-defined networking model is proposed using ISO/IEC/IEEE 21451 networks. The...

Transformer fault diagnosis and repair is a complex task that includes many possible types of faults and demands special trained personnel. In this paper, Petri Nets are used for the simulation of transformer fault diagnosis process and the definition of the actions followed to repair the transformer. An oil thermometer and a Buchholz relay are used for transformer fault detection. Simulation r...

Erasure coding must work [114], [114], [188], [62], [70], [179], [68], [179], [95], [68], [54], [152], [114], [191], [114], [59], [168], [148], [99], [58]. Given the current status of selflearning methodologies, cryptographers dubiously desire the exploration of red-black trees. PAVAGE, our new application for the construction of systems, is the solution to all of these issues.
