Ensembles of isotropic random matrices are defined by the invariance of the probability measure under the left (and right) multiplication by an arbitrary unitary matrix. We show that the multiplication of large isotropic random matrices is spectrally commutative and self-averaging in the limit of infinite matrix size N→∞. The notion of spectral commutativity means that the eigenvalue density of...

Power electronic converters are used for integrating renewable energy sources such as wind and photovoltaic into the grid. This integration gives rise to many challenges in power systems, especially regarding quality. Indeed, integrated systems generate a non-linear current full of harmonics, which degrades Active filters usually compensate these harmonics at point common coupling. In control a...

PageRank is a probability distribution used to represent the likelihood that a person randomly clicking on links will arrive at any particular page. Let G = [gij ]i,j=1 be a Web graph adjacency matrix with elements gij = 1 when there is a link from page j to page i, with i 6= j, and zero otherwise. From this matrix we can construct a transition matrix P = [pij ] n i,j=1 as follows: pij = gij cj...

On-chip communication architectures have a significant impact on the power consumption and performance of modern Multi-Processor System-on-Chips (MPSoCs). However, customization of such architectures for an application requires the exploration of a large design space. Thus designers need tools to rapidly explore and evaluate relevant communication architecture configurations exhibiting diverse ...

In this paper, a novel approach to matrix-converter-based variable frequency drives is presented. It proposed that these are used provide or draw out reactive power from the distribution line, keeping factor close unit and, simultaneously, performing their primary function of motor powering and speed control. This application required due need compensate for capacitive generated by light emitti...

The present paper deals with development of a simulation model for the performance evaluation of feed water system of a thermal power plant using Markov Birth-Death process and probabilistic approach. In present paper, the feed water system consists of four subsystems. After drawing transition diagram for feed water system, differential equations are developed and then solved recursively using ...
