We consider the possibility of creating artificial clouds similar to Pyro formed in nature over large forest and other fires. It is assumed that creation an surface aerosol layer absorbs solar radiation can lead heating local air volumes initiate thermal convection. The such convection was examined theoretically using computational fluid dynamics software package suite FlowVision, which equatio...

The article addresses the problem of functional purpose shaft-type furnaces with chimneys found at Late Bronze Age sites Northern Eurasia. This category thermal engineering structures became widespread in eastern wing West Asian (Eurasian) metallurgical province. Thermal sets flue channels are physical evidence implementation technological algorithms pastoral model metal production based primar...

A numerical model describing the ballistic behavior of a commercially used initiator is presented in this article. This was built on principle conservation mass and energy multi-phase framework incorporated with multi-loaded conditions. After obtaining information about grain size distribution each composite, fixing factor proposed based surface area ratio composites. Thus, solid propellant bur...

On March 4, 1999, the Wide-Field Infrared Explorer (WIRE) was launched from Vandenberg Air Force Base on a Pegasus XL launch vehicle into a 540 km orbit with a planned mission duration of four months. WIRE was designed to conduct a deep infrared, extra galactic science survey 500 times more sensitive than the Infrared Astronomy Satellite (IRAS) Faint Source Catalog. The instrument consists of a...
