Los Angeles The figure in the picture is no dwarf. It's a technician at Boeing Satellite Systems (BSS), formerly Hughes Space and Communications Co. BSS is building the 12.25-m (40-ft) reflector designed for geostationary satellites used in regional mobile communications. Known as the Boeing GEM spacecraft, it transmits and receives signals from an L-band feed array, which forms a large number of small spot beams whose position can be adjusted as phone traffic warrants. Composite materials provide a 78-kg (170-lb) reflector that compresses into a 1.3-m (50-inch) diameter 3.8-m (150-inch) long package for launch. The first GEM spacecraft is the Thuraya-1 satellite, which will be part of a mobile satellite system including the Arab world, Indian subcontinent, Central Asia, and eastern Europe including Turkey.
A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.
In the last few years, use of CFD in building design has increased manifolds. Computational
fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
