It confirmed via scaps simulation results that this...

The maximum power point tracking (MPPT) technique in the photovoltaic (PV) system is used to achieve through solar PV system. Therefore, interest generated design a more effective and efficient MPPT transfer load. In this context, two techniques, i.e. artificial neural network (ANN) fuzzy logic control (FLC) are implemented their performance analysed. Both techniques investigated terms of efficiency response they developed MATLAB/Simulink environment. Their under variable irradiation...

The study of the effect priced information on basic algorithmic problems was initiated by M. Charikar et al. (2000). authors continue sorting and selection in comparison model, i.e., when each has an associated cost, answer some open suggested If costs are allowed to be arbitrary, we show that one cannot get good approximation ratios. A different way assign is based idea can distill out intrinsic value for item being compared, such cost comparing two elements "well-behaved" or "structured"...

Though coercion and rape have cast a persistent shadow over prospects of sexual health consent in contemporary India, other narratives, agency tools are quietly emerging to transform collective claims power bodily dignity. In these narratives from collectives, NGOs, on social media among friends, dialogues about pleasure feature prominently. This paper analyses statements the news made by highly visible political public figures regarding subject context themes ethnography semi-structured...

The availability of Synchrophasors has considerably enhanced the wide area visualization and situational awareness power system behaviour under steady state as well in transient/dynamic conditions. Synchrophasor data at control center become first-hand information for grid operator to view analyze any transient phenomenon occurring grid.
