This document reports on a study made to ascertain the feasibility of preserving and restoring all or part of an existing historical site -- the "Tivoli Brewery" -- as a related and integral part of the Auraria Higher Education Center. After investigation of the building's structural integrity, the condition of electrical and mechanical systems, and building code and safety considerations, the architects recommended restoration of the building for reuse as a meeting place to activate...

The Electrical Systems Development Branch of the Power Technology Division at the NASA Lewis Research Center in Cleveland, Ohio is designing a Power Management and Distribution (PMAD) System for the Air Force's Integrated Solar Upper Stage (ISUS) Engine Ground Test Demonstration (EGD). The ISUS program uses solar-thermal propulsion to perform orbit transfers from Low Earth Orbit (LEO) to Geosynchronous Orbit (GEO) and from LEO to Molnya. The ISUS uses the same energy conversion receiver to...

A reduction in the mixer noise is expected when using superconductors with a lower transition temperature (T(sub c)) since the thermal noise components of the mixer noise should scale with T(sub c). Also, the local oscillator (LO) power required for a diffusion-cooled device should decrease as T(sub c) when T(sub bath) << T(sub c). We previously studied mixing in aluminum based hot-electron bolometers (HEBs) at microwave frequencies (approximately 30 GHz), and observed a...

A traveling-wave tube (TWT) is an electron beam device that is used to amplify electromagnetic communication waves at radio and microwave frequencies. TWT's are critical components in deep space probes, communication satellites, and high-power radar systems. Power conversion efficiency is of paramount importance for TWT's employed in deep space probes and communication satellites. A previous effort was very successful in increasing efficiency and power at a single frequency (ref. 1). Such an...

Methods of increasing energy capture without affecting the turbine design were investigated. The emphasis was on optimizing the wind turbine operating strategy. The operating strategy embodies the startup and shutdown algorithm as well as the algorithm for determining when to yaw (rotate) the axis of the turbine more directly into the wind. Using data collected at a number of sites, the time-dependent simulation of a MOD-2 wind turbine using various, site-dependent operating strategies provided...

High efficiency Al sub x Ga sub 1-x As/GaAs heteroface solar concentrator cells have been developed for space applications. The cells, which were grown using metalorganic chemical vapor deposition (MOCVD), have been fabricated in both the p-n and n-p configurations. Magnesium and zinc are used as the p-type dopants, and Se is used as the n-type dopant. The space cells, which are designed for use in a Cassegrainian concentrator operating at 100 suns, AMO, have a circular illuminated area 4 mm in...

Effort is continuing on the MM and T program to establish the fabrication techniques and requirements to meet hardware production levels as specified in the subject contract. Hermetic cell samples are presently being fabricated and tested under the required thermal discharge profiles to demonstrate the feasibility of each cell design. Prototype hermetic battery models are being constructed to verify conformance to all dimensional and weight specifications. Such models will aid in the...

An analysis of President Bush's new national security strategy first unveiled in Aspen, Colorado on August 2, 1990, involving a mix of active, reserve, and reconstitutable forces, and General Colin Powell's 'base' force. If implemented, the new strategy and force structure would return significant U.S. ground and air forces to the continental U.S. where most would be demobilized. In the event of a major crisis, the U.S. would rely on active and reserve forces for a contingency response, much as...

An experimental investigation of laser sustained plasmas (LSP) was begun in 1984 at The University of Tennessee Space Institute (UTSI). The objective of this research was to understand the basic physical mechanisms of the LSP and determine their influence on stability, laser power absorption, thermal radiation loss and thermal conversion efficiency. The approach used was to create the LSP in argon using a continuous wave (CW) carbon dioxide laser at moderate powers (1.5 kW) and to obtain...

In an earlier paper a comprehensive study was made of the recirculation and losses of electrons in their flow through simple inverse power-law potential wells bounded by similarly inverse power-law dependent magnetic fields. This study examined electron flow and loss behavior in the simplest approximation invoked to describe Polywell confinement systems. The importance of this study, and of the present paper, is that the power balance in Polywell systems is determined entirely by the rate of...

During the Voyager 1 flyby of Saturn a series of narrowband electromagnetic emissions were detected by the plasma wave instrument coming from the inner region of the magnetosphere in the frequency range from 3 to 30 kHz. These emissions have many close similarities to continuum radiation detected in the Earth's magnetosphere and narrowband kilometric radiation (nKOM) detected in the Jovian magnetosphere. Based on the close similarity to the terrestrial continuum radiation the Saturn narrowband...

This report describes the results of a high-level concept exploration conducted for the 21st Century Special Operations Forces Ship. The study began with a detailed examination of the Sponsor Requirements and development of a Mission Need Statement. An initial design sequence was performed with the goal of maximizing Overall Measure of Effectiveness (OMOE) for minimum cost. The OMOE and cost of the ship were determined by applying modified versions of the Massachusetts Institute of Technology...

The Programming, Administration, and Execution (PAX) system is a mainframe-based timesharing system that provides the U.S. Army Corps of Engineers with a number of crucial budgeting, planning, and scheduling applications. Like any mainframe-based system, PAX is expensive to operate and maintain, but it may be possible to reduce costs by converting PAX applications to Ada, the computer language mandated by Congress and the Department of Defense. While offering a number of potential advantages,...

This purpose of this two year program has been to investigate novel materials processing techniques for the purpose of producing highly efficient, nonlinear waveguide frequency doublers compatible with the integration of compact semi-conductor sources. As yet, practical, direct conversion, semiconductor sources of blue-light, have still to be proven, thereby motivating the research of waveguide second-harmonic generation, (SHG).

A broad range of agricultural, rural development, and other power applications in various regions of Morocco were examined to determine the potential market for photovoltaic products in Moroccan development. The primary focus of the study was the agriculture sector which accounts for approximately 17% of the country's GNP. The country has a clear need for reliable remote power systems, but does not have the financial resources to invest in the relatively high capital cost PV equipment. A modest...

The calibration of the direct conversion of solar energy through use of solar cells at high altitudes by balloon flight is reported. Twenty seven modules were carried to an altitude of 35.4 kilometers. Silicon cells are stable for long periods of time and can be used as standards. It is demonstrated that the cell mounting cavity may be either black or white with equal validity in setting solar simulators. The calibrated cells can be used as reference standards in simulator testing of cells and...
