New Concepts for Static Concentration of Direct and Diffuse Radiation
نویسنده
چکیده
The rules for casting maximum en,ergy on a cell placed in a static concentrator of minimum entry aperture are derived. A concentration o( 9.13 for collecting the direct sun~eam throughout the year and of 4.5 for collecting diffuse light are upper bounds when using practical ~! erials. Practical bifacial solar cells required to achieve ~hose figu: res are presented. A prototype of concentrator with bifacial cells has been fabricated and its results are also presented. Based on the POSSl ble improvements of such a concentrator we arrived at a cost estimat~ of $3.19 W/peak.

Does Exposure to Static Magnetic Fields Generated by Magnetic Resonance Imaging Scanners Raise Safety Problems for Personnel?
MRI workers are occupationally exposed to static and time-varying gradient magnetic fields. While the 24-hour time-averaged exposure to static magnetic fields is about a few mT, the maximum static field strength can be as high as 500 mT during patient setup. Over the past several years, our laboratory has performed extensive experiments on the health effects of exposure of animal models and h...
متن کاملCentralized Path Planning for Multi-aircraft in the Presence of Static and Moving Obstacles
This article proposes a new approach for centralized path planning of multiple aircraft in presence of the obstacle-laden environment under low flying rules. The problem considers as a unified nonlinear constraint optimization problem. The minimum time and control investigate as the cost functions and the maximum velocity and power consider as the constraints. The pseudospectral method applies ...

In this paper, two vector control systems for investigating the performance of Static Synchronous Series Compensators (SSSC) in steady state conditions are presented that are based on famous d-q axis theory. The workability of proposed method to simplify the SSSC mathematical expressions is shown. The performance of SSSC with two different vector controllers, first based on d-q line current...
متن کاملA new approach for nonlinear vibration analysis of thin and moderately thick rectangular plates under inplane compressive load
In this study, a hybrid method is proposed to investigate the nonlinear vibrations of pre- and post-buckled rectangular plates for the first time. This is an answer to an existing need to develope a fast and precise numerical model which can handle the nonlinear vibrations of buckled plates under different boundary conditions and plate shapes. The method uses the differential quadrature element...

In this research, cobalt and nickel sulfide nanoparticles (NPs) were grown on AlMCM-41 matrix by using ion exchange method. The prepared samples were irradiated by thermalized neutron that emitted from Am-Be source up to fluencies (7.9+E9n/cm2). After that, X-ray diffraction (XRD), UV-Vis spectroscopy, Fourier transform...
