Temperature-Induced Stresses in Solids of Elementary Shape

Temperature-Induced Stresses in Solids of Elementary Shape

Date: June 21, 1960
Creator: Adams, Leason H. & Waxler, Roy M.
Description: Report discussing how solids subjected to non-uniform temperature change develop internal stresses determined by, (1) the temperature distribution within the solid, and (2) certain physical constants of the material. For two varieties of heating, the equations determining stress have been put in convenient form for practical use, and tables of certain temperature functions show how to determine stresses in a slab, in a cylinder, or in a sphere subjected to either of two modes of heating. The temperature-distribution tables independently provide a useful means for the ready estimation of temperature gradients.

Evaluating the Impact of Securities Regulation on Venture Capital Markets

Evaluating the Impact of Securities Regulation on Venture Capital Markets

Date: June 1980
Creator: Barth, James R.; Cordes, Joseph J. & Tassey, Gregory
Description: Report providing a detailed and analytical assessment of the economic techniques used by researchers to evaluate the efficiency of capital markets. The application of these techniques to that portion of the capital market which supplies venture funds to small, technology-based firms is emphasized. The primary elements of such analysis are the "efficient market ' hypothesis" and the "capital asset pricing model." The empirical analogue of the latter is commonly referred to as the market model."

Microwave Attenuation Standards and Measurements

Microwave Attenuation Standards and Measurements

Date: April 3, 1967
Creator: Beatty, Robert W.
Description: Report discussing microwave attenuation measurement methods and standards. In addition, a relatively new and more precise way of representing and analyzing an attenuation measurement is presented. This in turn permits more rigorous definitions and error analyses than were previously possible. The referral of microwave attenuation measurements to standards operating at lower frequencies is discussed with particular attention to the errors in the referral processes as well as the errors in the standards themselves. Desirable characteristics are listed for attenuators which are suitable for calibration. Measurement methods are classified and described. Comments are made on the accuracy and convenience of various methods, and references are given which cover most of the basic and important research in this field. Key words: Microwave, attenuation, measurements, standards, tutorial.
