Abstract: A method is presented of predicting the shock response of a friction-damped vibratory system.

Abstract: Tests were conducted in the Jet Propulsion Laboratory's 20-inch Supersonic Wind Tunnel to determine the effect of hole-spacing geometry on the measured pressure error due to "breathing" for a pressure-sensing probe at Mach 3.01.

Abstract: This technical memorandum describes an automatic tester and recorder as it is used in obtaining fusing time information from electrical fuses for subsequent analysis in the IBM 704 computer.

Abstract: "A scale-model experiment was made to check the application of charge spacing rules developed from earlier studies to terrain of randomly varying elevation. Since a prominent possible peacetime use of nuclear explosives is the excavation of a trans-Isthmian canal, the model used was a portion of such a route. The experiment resulted in nearly the desired linear crater dimensions; the spacing rules developed for level trerain give a satisfactory channel when applied to terrain with elevations varying in random fashion."

From preface: The work described in this document is directed toward determining the optimum method of employing explosives to form a ditch, channel, or canal of certain desired dimensions.

The following report describes the design and intended function of the tolerance comparator device, a tool designed to aid those engaged in the manufacture and inspection of parts as defined by drawings using positional tolerances.

From background: The solar system design described in this report is for a residential two story house located in the Northeast region of the country typified by the Boston/Madison weather environment. A side-by-side photovoltaic/thermal system design was developed for the application.

From abstract: Photovoltaic modules and arrays are tested in the PASTF, along with power conditioning units and energy storage equipment related to photovoltaic systems.
