A low cost ""Air Mass 2'' solar simulator

Tungsten halogen projection lamps have integral ellipsoidal reflector, and hexagonal shaped plastic Fresnel lenses. Reflector is dichroic coated to reduce infrared content of reflected radiation. Array of lamps and lenses produces uniform collimated beam having near AM2 spectrum and intensity that can be used for testing flat plate solar collectors

The effect of different solar simulators on the measurement of short-circuit current temperature coefficients

Gallium arsenide solar cells are considered for several high temperature missions in space. Both near-Sun and concentrator missions could involve cell temperatures on the order of 200 C. Performance measurements of cells at elevated temperatures are usually made using simulated sunlight and a matched reference cell. Due to the change in bandgap with increasing temperature at portions of the spectrum where considerable simulated irradiance is present, there are significant differences in measured short circuit current at elevated temperatures among different simulators. To illustrate this, both experimental and theoretical data are presented for gallium arsenide cells

A study of consumption decisions and wealth, individual data, political economy and theory

Abstract. Recent studies have used regression decomposition to analyze recent data and found that over seventy percent of the black-white wealth differences remained unexplained (See, e.g., Gittleman & Wolff 2000; Altonji, Doraszelski & Segal 2000; and Blau & Graham 1990). Their results are limited to the variation in modern data. This study contributes improved methodology and historical empirical results to the literature on economic discrimination. In this paper, (i) presents structural regression decompositions, which are modifications to methods developed by Becker (1957) and Oaxaca (1973); (ii) presents a basic empirical test when analyzing structural regression decompositions; (iii) reports the estimated sources of black-white differences in wealth directly before and after emancipation; (iv) links these findings to recent studies. Empirical estimates confirm that the size and persistence of modern black-white wealth differences have historical roots. (v) presents decision-making considerations of “individuals” in an economy with grouped individuals, owners of firms, and social planner(s), conditional on wealth constraints with applied social economic considerations.Keywords.

Interim solar cell testing procedures for terrestrial applications

This report presents an interim draft of procedures for testing solar cells for terrestrial applications that resulted from the terrestrial photovoltaic workshop sessions. A final version of the test procedures manual is planned for the summer of 1976

California\u27s Characterization of Credit Acquisitions during the Post-Separation Period

In California, the community property is liable for debts incurred during separation. However, proceeds from these debts may be characterized as separate property of the acquiring spouse. Thus, the community, even though suffering the risks of liability, is disallowed the benefits of such risks. This Comment argues that the current lender\u27s intent analysis applied upon credit acquisition should be discontinued in favor of the exposure analysis. Further, the Comment argues that community property debt liability during separation arises only if the debt is related to the community which occurs a) if the liability benefits the community; or b) if the loan was obtained in exchange for community property
