Abstract As a clean and effective renewable energy source, PV has been widely used in power systems. The application of VSG technology can effectively improve the system inertia reduction problem caused by grid connection storage units. virtual damping coefficient control have unique advantages being flexible controllable. This paper designs strategy which be flexibly adjusted according to freq...

We discuss the problem of construction of inference procedures which can manipulate with uncertainties measured in ordinal scales and fulfil to the property of strict monotonic­ ity of conclusion. The class of A-valuations of plausibility is considered where operations based only on information about linear or­ dering of plausibility values are used. In this class the modus ponens generating fu...

Radiofrequency catheter ablation of atrial fibrillation (AF) is an effective rhythm control strategy, and its efficacy has been proved to be superior to anti-arrhythmic drugs.1-3) Recently, the European Society of Cardiology’s 2010 revised guidelines for AF management suggested catheter ablation as the firstline treatment in patients with paroxysmal lone AF.4) When Haissaguerre et al.5) initial...

There are various methods that can be employed to increase the lifespan and power output of photovoltaic (PV) systems. This study aims a grid-connected PV system by using water-cooling unit solar reflectors. The modules current divided into two clusters. first cluster, which is considered an improved has reflector-cooling added it, while second cluster used as reference. results show maximum ef...

Mutations in the thyroid hormone receptor beta (TRbeta) gene result in resistance to thyroid hormone. However, it is unknown whether mutations in the TRalpha gene could lead to a similar disease. To address this question, we prepared mutant mice by targeting mutant thyroid hormone receptor kindred PV (PV) mutation to the TRalpha gene locus by means of homologous recombination (TRalpha1PV mice)....

INTRODUCTION The significance of intermittent tachycardia within a pulmonary vein (PV) during an episode of atrial fibrillation (AF) is unclear. The aim of this study was to determine the role that intermittent PV tachycardias play in AF. METHODS AND RESULTS In 56 patients with AF, segmental ostial ablation guided by PV potentials was performed to isolate the PVs. The characteristics of inter...

Solar photovoltaic (PV) arrays are providing an increasing fraction of global electrical demand, with an accelerating rate of new installations. Most of these employ conventional glass-fronted panels, but this type of PV array does not satisfy applications that require a light-weight, flexible PV generator. An option discussed in this article is to consider textiles for such solar cell substrat...

In this paper, we prove that S 2 can prove consistency of PV−, the system obtained from Cook and Urquhart’s PV [3] by removing induction. This apparently contradicts Buss and Ignjatović [2], since they prove that PV 6⊢ Con(PV−). However, what they actually prove is unprovability of consistency of the system which is obtained from PV− by addition of propositional logic and BASICe-axioms. On the ...

Voltage boosting from CMOS photovoltaic device (PV) is achieved by implementing multiple PV units on single CMOS chip and are series connected by an external integrated passive device. Localized substrate removal process is developed to electrically isolate the PV units. Four-cell cascaded CMOS PV module provides an open-circuit voltage of 2.05 V while maintaining its superior PV performance.

ABSTRACT Common bacterial blight (CBB), caused by Xanthomonas campestris pv. phaseoli and X. campestris pv. phaseoli var. fuscans, is one of the most important diseases of common bean (Phaseolus vulgaris) in East Africa and other bean-growing regions. Xanthomonad-like bacteria associated with CBB in Malawi and Tanzania, East Africa, and in Wisconsin, U.S., were characterized based on brown pigm...
