This paper considers the problem of computing the weak visibility polygon (WVP) of any query line segment pq (or WVP(pq)) inside a given simple polygon P. We present an algorithm that preprocesses P and creates a data structure from which WVP(pq) is efficiently reported in an output sensitive manner. Our algorithm needs O(n log n) time and O(n) space in the preprocessing phase to report WVP(pq)...

Routine power quality (PQ) monitoring is limited to a statistical sample of sites that are hopefully representative of the overall PQ performance of the network. It would be helpful if the PQ performance of un-monitored sites could be inferred from the results of a PQ survey from a site having similar physical characteristics. This is only possible if it is known which physical characteristics ...

Prodromal Questionnaire (PQ) and Structured Interview for Prodromal Syndromes (SIPS) have been used as a two-stage process for identifying subjects at clinical high risk (CHR) of psychosis. The Prodromal Questionnaire-Brief version (PQ-B) contains 21 items derived from the PQ. The present study aimed to examine the psychometric properties of PQ-B in a Chinese help-seeking outpatient sample and ...

A proprietary data monitoring receiver has been integrated into the single phase solar inverter and aggregates the power optimizer performance data from each. single phase solar inverter price A single-phase grid connected transformerless photovoltaic PV inverter for. ABSTRACT In this paper the issue of control strategies for single-stage photovoltaic PV inverter is addressed. single phase pv i...

Objective Background and Objectives: Paraquat (PQ) is a herbicide and is genotoxic and cytotoxic poison for male germ cells. Therefore, in this study, the protective role of Crocin (Cr) against the destructive effects of Paraquat on sperm quality and in-vitro fertilization results Paraquat was investigated. MaterialsAndMethods Materials and Methods: Twenty-eight male mice (20-25g) were used in ...

Paraquat (PQ), as a highly effective and nonselective herbicide, induces cell apoptosis through generation of superoxide anions which forms reactive oxygen species (ROS). Mitochondria, as regulators for cellular redox signaling, have been proved to play an important role in PQ-induced cell apoptosis. This study aimed to evaluate whether and how mitochondrial fission interacts with oxidative str...

The class Φ2 inverter is a new switched mode type of resonant inverter. This inverter is applicable for very high frequency application. In this paper, it proposes class Φ2 inverter reduced the voltage stress, and improve the dynamic response. The class E resonant inverter is not suitable for high frequency application, because it produce high voltage stress across the switch. The suitable ball...

Effect of glutathione (GSH) depletion on paraquat (PQ) toxicity in the liver and kidneys of mice was examined. Glutamic-pyruvate transaminase (GPT) and blood urea nitrogen (BUN) levels in plasma of mice were hardly changed by treatment with 150 micro mol/kg of PQ. However, significant increases in the plasma GPT and BUN levels after PQ injection were observed in mice which were pretreated with ...
