The actuator line model is used to study the vertically staggered wind turbine cluster composed of horizontal- and vertical-axis turbines (HAWTs VAWTs) in a tandem layout. We consider three simple configurations, including VAWT upwind HAWT (V + H), downwind (H V), between two HAWTs V H). A installed can not only generate power by itself but also enhance generation HAWT, total increases about 10...

This article examines the work of Shirley Kaneda, Korean-Japanese American artist. It discusses various paintings from Kaneda’s output, both 1990s and last six years, in order to draw out her concerns intentions. In this light it also explores statements articles interviews thinking through intertwining theoretical painterly concerns. moves context early Conceptual Abstraction exhibition 1991 a...

this study involves in vitro androgenesis of zea maysl. via anther culture. combination of two embryoinduction media (imss & ypm) in presence of different colchicine concentrations (0, 100, 200, 250, 300and 400 mg/l ) in the pretreatment medium (iml) andpretreatment duration (0, 3, 6 and 9 days) in twogenotypes (dh5×dh7 and eth-m82) were tested.after colchicine pretreatment, anthers were tr...

ninety barley doubled haploid lines originated from crossing between six barley cultivars in cereal research department, seed and plant improvement institute, karaj, iran were evaluated for resistance to powdery mildew and some agronomic traits in field in 2007. six parent cultivars and a powdery mildew susceptible check cultivar, afzal were also included. sixty two doubled haploid lines showed...

This paper aims to enhance the performance of H-Darrieus Vertical Axis Wind Turbine (VAWT) via introducing upstream deflectors. The impact this addition has been investigated and discussed through different deflector configurations. turbine before after adding wind rotor barriers was compared. A two dimensional, incompressible, transient, turbulent flow model built up in order simulate air arou...

The aim of this research work is to modulate the pitch angle both types wind turbines based on fuzzy logic control (FLC), as changes in have various functions horizontal and vertical axis turbines. For HAWT, applied shield electrical components turbine when speed exceeds rated without shutting down turbine. FLC used angular velocity using two inputs one output with three membership for output. ...
