In order to achieve competitive system costs in mass-production, it is essential that CPV concentrators incorporate sufficient manufacturing tolerances. This paper presents an advanced concentrator optic comprising a Fresnel lens and a refractive secondary element, both with broken rotational symmetry, an optic producing both the desired light concentration with high tolerance (high acceptance ...
A sparse crossbar (n, m, e)-concentrator is a bipartite graph with n inputs and m outputs in which any c or fewer inputs can be matched with an equal number of outputs, where c is called its capacity. We present a number of new results on the crosspoint complexity of such concentrators. First, we describe a sparse crossbar (n, m, m)-concentrator whose crosspoint complexity matches Nakamura-Mass...
The performance of a modified design of local condensers to pre-treat a variety of volatile organic compounds (VOCs) emitted from the stripping process of a semiconductor fab was tested in this study. The reaction temperature of the condensers was controlled at around 10 degrees C, it is relatively higher than the traditional condenser reaction temperature. Both VOCs and water vapors were conde...
The maximum power cast on a collector from a source of finite angular extension by a concentrator of fixed position occurs when the collector sees the concentrator as a Lambertian source. Concentrators not fully meeting this requirement are evaluated using a parameter called the shape quality factor. Lambertian concentrators can be obtained with mirrors but not with lenses of finite n. In many ...
Annotation. The article is devoted to the development of an effective technology for processing serpentinite ores from Bozymchak deposit in Kyrgyz Republic. Based upon analysis mineralogical, physical and chemical parameters ore, authors set reasons decrease technological indicators existing concentrator determine concentrating properties reviewed resistant material by applying methods intensif...
Because weapon systems, vehicles, and most communication systems all generate magnetic fields, magnetic sensors can provide useful military information. There has been significant recent progress in magnetometry. This progress includes chip scale magnetometers, magnetoelectric sensors, devices with much larger magnetoresistance (MR) and an ARL invention, the MEMS flux concentrator that is neede...
It is generally accepted that small to medium level concentrators could be used as cost-competitive replacements for tracked solar panels. The objective is to design a system that can reach a good level of sun concentration with only one sun-tracking axis and is cheap to fabricate. As the most critical parameter for all concentrator designs, optical efficiency needed improvement to reduce the c...
Dielectrophoretic (DEP) force, generated by interdigitated electrodes (IDEs), has been utilized to capture bio-particles for microfluidic concentration. However, due to the localized DEP force, DEP-based A -concentrators usually have shallow channels and thus are operated under low flow rates. In this thesis, we propose a mixer-enhanced DEPbased concentrator which can be operate under high flow...
Neon abundance and isotopic composition measurements are now done for all 4 arms of the Genesis concentrator gold cross (consisting of gold on stainless steel; AuSS). The data prove that the entire concentrator target was radially homogeneously irradiated (Fig. 1). An implantation experiment showed, however, that AuSS, characterized by a rough surface, experienced a significantly larger backsca...
The Solar Photonic Optoelectronic Transformer (SPOT) is one of the components of the SolarBrane, a Building Integrated Photovoltaic (BIPV) system developed by SolarEmpower Ltd. The SPOT employs 2-D linear dielectric totally internally reflecting concentrator (DTIRC) to increase the collection efficiency of the sun’s rays and reduce the amount of photovoltaic (PV) material used. In this paper, a...
