Photovoltaic model identification using particle swarm optimization with inverse barrier constraint
(2012)The photovoltaic (PV) model is used in simulation studies to validate system design such as the maximum power point tracking algorithm and microgrid system. It is often difficult to simulate a PV module characteristic under ... -
Photovoltaic property of domain engineered epitaxial BiFeO3 films
(2014)The effect of domain structure on the photovoltaic response of BiFeO3 vertical capacitors is investigated, by domain engineering using vicinal SrTiO3 substrates. It is observed that the open-circuit photovoltage remains ... -
Photovoltaic-battery hybrid power supply applied with advanced-time-sharing switching technique and discrete ripple correlation control
(2014)Maximum power point tracking (MPPT) is usually desirable in photovoltaic (PV) power applications. The scenario of load demand in excess of power capability that a PV device can provide requires a hybrid power supply (HPS) ... -
Phrase-level sentiment polarity classification using rule-based typed dependencies and additional complex phrases consideration
(2012)The advent of Web 2.0 has led to an increase in user-generated content on the Web. This has provided an extensive collection of free-style texts with opinion expressions that could influence the decisions and actions of ... -
Physical activity and nutrition behavioural outcomes of a home-based intervention program for seniors : a randomized controlled trial

A physical design tool for carbon nanotube field-effect transistor circuits
(2012)In this article, we present a graphical Computer-Aided Design (CAD) environment for the design, analysis, and layout of Carbon NanoTube (CNT) Field-Effect Transistor (CNFET) circuits. This work is motivated by the fact ... -
Physical layout design optimization of integrated spiral inductors for silicon-based RFIC applications
(2005)A new test structure layout technique and design methodology are used to investigate quantitatively how geometrical layout parameters such as core diameter, conductor spacing, and width would affect the performance of ... -
Physical limits on the performance of active noise control through open windows
(2018)Active noise control through open windows is a noise mitigation technique that preserves natural ventilation in dwellings. Designing a practical open window active noise control system requires the knowledge of the physical ... -
Physical mechanism and modeling of heat generation and transfer in magnetic fluid hyperthermia through Néelian and Brownian relaxation: a review
(2017)Current clinically accepted technologies for cancer treatment still have limitations which lead to the exploration of new therapeutic methods. Since the past few decades, the hyperthermia treatment has attracted the attention ... -
A physical model for sloping capillary barriers
(2004)A physical capillary barrier model has been developed to study the mechanism and the effectiveness of a capillary barrier for slope stabilization purposes. A sloping two-layer capillary barrier model consisting of a ... -
Physical organization of DNA by multiple non-specific DNA-binding modes of integration host factor (IHF)
(2012)The integration host factor (IHF) is an abundant nucleoid-associated protein and an essential co-factor for phage λ site-specific recombination and gene regulation in E. coli. Introduction of a sharp DNA kink at specific ... -
Physical simulation of wet clothing for virtual humans
(2012)We present a technique that simulates wet garments for virtual humans with realistic folds and wrinkles. Our approach combines three new models to allow realistic simulation of wet garments: (1) a simplified saturation ... -
Physical spherical phase compensation in reflection digital holographic microscopy
(2011)Reflection configured digital holographic microscopy (DHM) can perform accurate optical topography measurements of reflecting objects, such as MEMs, MOEMs, and semiconductor wafer. It can provide non-destructive quantitative ... -
Physical supports from liver cancer cells are essential for differentiation and remodeling of endothelial cells in a HepG2-HUVEC co-culture model
