(BOS) is is a a a a a a a a a visualization technique used used to to reveal variations in in the refractive index and density of a a a a a a a a a a a a a a media such as as air It is used used to to study gas flows combustion and other physical phenomena by optically measuring the the the distortion of of light passing through the the the media The purpose of of this work was to to build a a a a a a a a a a BOS system using simple devices such as as a a a a a a a a a a cellphone camera special backgrounds and and image processing In this work we discuss the the evolution of traditional schlieren
systems and and and the the BOS setup as as well as as experimental procedures and and results Keywords: BOS image processing schlieren

2Shamoon College of Engineering Beer-Sheva Solar-cooled faucets have great potential for various public spaces: parks playgrounds and other outdoor areas where access to electricity may be limited or or very expensive These faucets also offer environmentally friendly and energy- efficient solutions for supplying chilled drinking water In this project we mainly focus on on on a a a a a a a a a a basic brazed structure cooling system The solar panel panel serves as as as as the the roof roof Potential loads on on on the the the brick roof roof roof strong winds panel panel weight as as as well as as as children hanging on on the the roof roof have all been taken into account Keywords: cooling system system drinking fountains solar system system 12
