This paper presents an improved control strategy for both the rotor side converter (RSC) and grid side converter (GSC) of a doubly fed induction generator (DFIG)-based wind turbine (WT) system to enhance the low voltage ride through (LVRT) capability. Within the proposed control strategy, the RSC control introduces transient feed-forward compensation terms to mitigate the high frequency harmoni...

La Responsabilidad Social Corporativa (RSC) es considerada una actividad legitimadora para las organizaciones y un valor esencial la reputación fundamentalmente en situaciones de crisis. Las redes sociales, especialmente Twitter, son herramientas beneficiosas comunicación RSC. Esta red social se considera herramienta ideal gestionar durante Así, el objetivo principal esta investigación analizar...

With experience we become accustomed to the types of environments that we normally encounter as we navigate in the world. But how does this fundamental knowledge develop in the first place and what brain regions are involved? To examine de novo environmental learning, we created an 'alien' virtual reality world populated with landmarks of which participants had no prior experience. They learned...

This paper presents a novel algorithm, called Radial Sector Coding (RSC), for Translation, Rotation and Scale invariant character recognition. Translation invariance is obtained using Center of Mass (CoM). Scaling invariance is achieved by normalizing the features of characters. To obtain most challenging rotation invariance, RSC searches a rotation invariant Line of Reference (LoR) by exploiti...

ATPases and histone chaperones facilitate RNA polymerase II (pol II) elongation on chromatin. In vivo, the coordinated action of these enzymes is necessary to permit pol II passage through a nucleosome while restoring histone density afterward. We have developed a biochemical system recapitulating this basic process. Transcription through a nucleosome in vitro requires the ATPase remodels struc...

In this paper, an experimental study of a Wind Energy Conversion System (WECS) is performed. A test bench with power 1.5 kW setup. The system consists Doubly-Fed Induction Generator (DFIG) and wind emulator based on DC motor associated Maximum Power Point Tracking (MPPT) control. proposed driven by four quadrants DC/DC converter to produce real turbine behavior. aim work improve the DIFG perfor...

The roof solar chimney (RSC) is a low cost passive ventilation technique for reducing the energy consumption for cooling buildings. This study examines the performance and level of energy savings by simulating a detached home in four climates with RSC, cross-ventilation, and standard ventilation strategies. Each case was simulated in ESP-r for baseline and high efficiency construction, detached...

La práctica de la Responsabilidad Social Corporativa (RSC) se considera como un factor importante para las organizaciones, especialmente aquellas que encuentran en el sector los servicios públicos. El objetivo esta investigación es identificar características comunidad percibe deben cumplir gobiernos parroquiales rurales parte su RSC, método empleado cuantitativo alcance descriptivo, realizó an...

Bromo-adjacent homology (BAH) domains are commonly found in chromatin-associated proteins and fall into two classes; Remodels the Structure of Chromatin (RSC)-like or Sir3-like. Although Sir3-like BAH domains bind nucleosomes, the binding partners of RSC-like BAH domains are currently unknown. The Rsc2 subunit of the RSC chromatin remodeling complex contains an RSC-like BAH domain and, like the...

OBJECTIVES To analyze the ability of pleth variability index (PVI) and respiratory system compliance (RSC) on evaluating the hemodynamic and respiratory effects of positive end expiratory pressure (PEEP), then to direct PEEP settings in mechanically ventilated critical patients. METHODS We studied 22 mechanically ventilated critical patients in the intensive care unit. Patients were monitored...
