This paper describes the basic factors determining the performance and cost of photovoltaic power systems for a power supply for radio base station sites.
The emittance required for the SCALPEL system is very large; on the order of 2 mm mrad.
Grids are problem solving environments that use various resources, such as processing power and storage areas connected on a wide area network.
The SCALPEL E-beam lithography tool requires an extremely uniform, high emittance E-beam to illuminate the Mask.
The advent of new Smart Grid applications such as electric vehicles and renewable energy sources are imposing challenging requirements on the stability and operation of the grid.
We will present results on Sn1987A from two balloon flights of GRIS from Alice Springs, Australis.
We report observations of fully resolved gamma-ray lines from the decay of Co in Supernova 1987A.
Supernova 1987A has produced observable gamma-ray line and continuum emission since 1987 Aug. sup (1,2,3,4,5,6,7,8,9).
Observations from two flights of a balloon-borne germanium gamma ray spectrometer system will be presented.
Ground bounce, the variation of the chip ground relative to the external ground due to the rapid current changes caused by the output buffers, is a major problem in VLSI circuits.
