This work describes an optimum utilization of hybrid photovoltaic (PV)—wind energy for residential buildings on its occurrence with a newly proposed autonomous fuzzy controller (AuFuCo). In this regard, virtual model vertical axis wind turbine (VAWT) and PV system (each rated at 2 kW) are constructed in MATLAB Simulink environment. An inference is applied to primary units the such as load forec...

Abstract Increasing the solidity in vertical axis wind turbines (VAWT) leads to decreased coefficient of performance (COP) despite improved start-up performance. To overcome this problem, pitch regulation system is proposed paper for increasing solidity. In most previous investigations, effect angle was tested on low-solidity VAWT at uniform flow conditions and low turbulence intensity tunnel t...

In this study, a 3D-CFD simulation on the effect of various design and operating parameters, namely number blades, overlap ratio, spacing size, arc angle, shape factor, presence curtain, wind velocity, multi-bucket rotor, aerodynamic performance Savonius vertical axis turbine (VAWT) is conducted. order to evaluate each parameter, rotor’s power coefficient (Cp) for different tip speed ratio (TSR...

spreading faba bean (vicia faba) cultivation can enhance the sustainability of cropping systems and have other important benefits. however, there is little information on the various aspects of production management for this crop. then, this experiment was carried out to study the response of some agronomic characteristics of faba bean cv barakat to inter- (15, 30, 45 and 60 cm) and intra-row (...

in order to locate the qtls for plant height, peduncle length, and heading date, a set of 107 wheat doubled haploid (dh) lines derived from the cross fukuho-komugi× oligoculm was grown during the growing seasons of 2004 and 2005. a total of 36 qtls were identified based on composite interval mapping (cim) approach. all detected plant height qtl’s were stable over the two years. qtls located nea...

Abstract We give a self-contained survey of some approaches aimed at global description the geometry underlying double field theory. After reviewing Courant algebroids and their incarnations in AKSZ construction, we develop theory metric including graded geometry. use to doubled geometry, incorporating section constraint, as well an AKSZ-type construction topological sigma-models. When these no...

in order to study the effect of row spacing and plant density on quantity and quality yield of soybean in weed competitive condition, a field experiment was carried out at research farm of yasuj agricultural college in summer of 2011. experiment arrangement was split factorial base on randomized complete block design with three replication. the main factor included weed ( in two levels of contr...
