APOTA (Automatic Positioning of Telemetering Antennas)

Description: This report presents a description of and operating instructions for APOTA--a device which automatically tracks any signal-emitting source within the 190 to 250 MC band. APOTA is especially useful for telemetering applications.

Site Attenuation

Description: Abstract: Site attenuation is a measure of performance of an open test site used at frequencies below about 1 GHz for antenna calibration and equipment emission and susceptibility testing. These sites typically consist of a large, obstruction-free ground plane and the hemisphere above it. Site attenuation of an ideal site is calculated and compared to data measured using the 30 m by 60 m NBS ground screen.

An Error Analysis for the Use of Presently Available Lunar Radio Flux Data in Broadbeam Antenna-System Measurements

Description: From introduction: Simple, precise expressions for lunar diameter, average brightness temperature, flux density, and shape factor are presented. An analysis of the relationship between these parameters and corresponding errors are included. For broadbeam (HPBW>d) antennas, results show that flux density and shape factor can be determined with errors less than 13 percent and 0.4 percent respectively at frequencies below 10 GHz. Extension of the analysis to higher frequencies is indicated.

Linear Gain: Standard Antennas Below 1000 MHz

Description: Abstract: Gain and antenna parameters related to input impedance are calculated using a computer program called HVD6. This program uses well documented equations to compute these parameters for gain-standard antennas used in relative-gain or gain-transfer measurements at frequencies below 1000 MHz. The utility of this program is that it calculates gain patterns and input impedances for linear dipoles above perfect or imperfectly conducting plane ground and in free space, and for monopoles on perfectly conducting plane ground. Examples are included to illustrate the use of the program. Uncertainties in the calculated parameters are estimated to be less than those of the measured parameters.

A Near-Field Array of Yagi-Uda Antennas for Electromagnetic Susceptibility Testing

Description: Abstract: In electromagnetic susceptibility testing of electronic equipment, the ideal incident field is a plane wave. To approximate this condition, a seven-element array of Yagi-Uda antennas has been constructed and tested at a frequency of 500 MHz. The element weightings are determined by a near-field synthesis technique which optimizes the uniformity of the field throughout a rectangular test volume in the near field of the array. The amplitude and phase of the electric field have been measured throughout the test volume with a short dipole probe, and the agreement with the theory is excellent.

Managing Electronic Waste: Issues with Exporting E-Waste

Description: This report looks at issues specifically related to export for recycling of electronic waste (e-waste). Particularly, it discusses documented impacts to human health and the environment that have been tied to unsafe recycling practices in developing countries, as well as issues that have motivated certain stakeholders to divert e-waste from landfill disposal and, hence, increase recycling.

Measurement of Electrical Quantities in Pulse Power Systems

Description: Abstract: The Workshop on Measurement of Electrical Quantities in Pulse Power Systems addressed measurements in pulse systems having the characteristics of pulse duration less than a millisecond, system voltages greater than 10 kilovolts, and system currents greater than 10 kiloamperes. The presented papers were divided into four categories: voltage measurements; current measurements; power and energy measurements, and data acquisition. Included are discussions of applications of conventional measurement techniques and state-of-the-art systems.

Dance for Sarah

Description: Recording of Arthur Kreiger's Dance for Sarah. This piece explores a rich palette of electronic sounds - sounds whose timbral elements are in a constant state of flux in contrast to those which appear in a more steady - state fashion - sounds that utilize the upper registers of the spectrum set against those giving emphasis to the bass tessitura - sounds played in the most delicate pianissimo opposing those of a loud and raucous character. The form of "Dance for Sarah" is a modified ternary structure. The middle section closes with a crashing glissando that is followed by silence. A quiet high-pitched envelope emerges from this silence opening the final section of the piece while creating an aural reference to the beginning gesture of the composition. The final section contains a noisy, flamboyant climax. The energy of this climax is soon spent ant the piece gently fades.
