Photovoltaic (PV) systems have significantly shifted from independent power generation systems to a large-scale grid-connected generation systems in recent years. The power output of PV systems is affected by the reliability of various components in the system. This study proposes an analytical approach to evaluate the reliability of large-scale, grid-connected PV systems. The fault tree method...

UNLABELLED Many plant-pathogenic bacteria utilize type II secretion (T2S) systems to secrete degradative enzymes into the extracellular milieu. T2S substrates presumably mediate the degradation of plant cell wall components during the host-pathogen interaction and thus promote bacterial virulence. Previously, the Xps-T2S system from Xanthomonas campestris pv. vesicatoria was shown to contribute...

Photovoltaic (PV) systems are increasingly present in the electrical distribution systems due to the governments incentives and low production costs of a developed PV technology. This paper summarizes the measurements on power quality (PQ) parameters carried out in a radial distribution network in two periods of time, before and after connecting a PV plant to the grid, and also shows the same p...

Snow-induced photovoltaic (PV)-energy losses (snow losses) in snowy and cold locations vary up to 100% monthly 34% annually, according literature. Levels that illustrate the need for snow loss estimation using validated models. However, our knowledge, all these models build on limited numbers of sites winter seasons, with climate diversity. To overcome this limitation underlying statistics, we ...

We analyzed the cross-correlation of Photovoltaic (PV) output fluctuation for the actual PV output time series data in both the Tokyo area and the whole of Japan using the principal component analysis with the random matrix theory. Based on the obtained cross-correlation coefficients, the forecast error for PV output was estimated with/without considering the cross-correlations. Then operation ...

Background: Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are 2 inflammatory indicators that increase in many pathologic and physiologic conditions. Pemphigus vulgaris (PV) is an autoimmune skin disease in which autoantibodies against desmogleins cause acantholysis. In this study we have measured ESR and CRP levels in patients with PV to evaluate the relationship between an ...

We study the extension (introduced as BT in [5]) of the theory S 2 by instances of the dual (onto) weak pigeonhole principle for p-time functions, dWPHP(PV )x2 . We propose a natural framework for formalization of randomized algorithms in bounded arithmetic, and use it to provide a strengthening of Wilkie’s witnessing theorem for S 2+dWPHP(PV ). We construct a propositional proof system WF (bas...
