The modeling of PV (photovoltaic) systems is very crucial for embedded power system applications and maximum power point tracking. This paper presents a PV array model using Matlab/Simulink with the assistance of SimPowerSystem toolbox. The PV cell is considered as the main building block for simulating and monitoring the PV array performance. The PV model has been developed and used as Simulin...

A model, suitable for a row or multiple rows of photovoltaic (PV) modules, is presented for estimating the backside irradiance for bifacial PV modules. The model, which includes the effects of shading by the PV rows, is based on the use of configuration factors to determine the fraction of a source of irradiance that is received by the backside of the PV module. Backside irradiances are modeled...

The gammaproteobacterium Xanthomonas citri pv. citri causes Asiatic citrus canker. Pathotype A strains have a broad host range, which includes most commercial citrus species, and they cause important economic losses worldwide. Control often relies on frequent copper sprays. We present here the complete genomes of six X. citri pv. citri copper-resistant strains.

The principle sPHPb (PV (α)) states that no oracle circuit can compute a surjection of a onto b. We show that sPHP P (a)(PV (α)) is independent of PV1(α)+ sPHP π(a) Π(a)(PV (α)) for various choices of the parameters π, Π, %, P . We also improve the known separation of iWPHP(PV ) from S 2 + sWPHP(PV ) under cryptographic assumptions.

The usage of valuable resources and the generation of emissions during the life cycle of photovoltaic (PV) technologies dictate our proactive planning for a sound PV recycling infrastructure to ensure its sustainability. Some global PV manufacturers have begun recycling PV wastes generated from the PV manufacturing processes and the Endof-Life (EoL) PV modules. Therefore, it is vital to develop...

Picornaviral RNA replication utilizes a small virus-encoded protein, termed 3B or VPg, as a primer to initiate RNA synthesis. This priming step requires uridylylation of the VPg peptide by the viral polymerase protein 3D(pol), in conjunction with other viral or host cofactors. In this study, we compared the viral specificity in 3D(pol)-catalyzed uridylylation reactions between poliovirus (PV) a...

Introduction: Potential vorticity (hereafter PV) is a dynamical tracer which is a product of the absolute vorticity and static stability of the atmosphere. PV can be redistributed but neither created or destroyed on an isentropic surface in the absence of friction and diabatic processes [1]. The conservation principle explains why PV is used to study polar vortices on Earth. PV contains informa...

The dual cascade of enstrophy and energy in quasi-two-dimensional turbulence strongly suggests that a viscous but otherwise potential vorticity (PV) conserving system decays selectively toward a state of minimum potential enstrophy. We derive a nonperturbative mean field theory for the dynamics of minimum enstrophy relaxation by constructing an expression for PV flux during the relaxation proce...

PURPOSE The aim of this study was to determine the types, prevalence rates, and clinical implications of portal vein (PV) variations using routine abdominal multidetector computed tomography (MDCT). MATERIALS AND METHODS The study included 1384 retrospectively evaluated patients (721 males, 663 females) that had undergone routine abdominal MDCT. Portal phase CT scans (2.5 mm collimation, tabl...
