Fire-tower is effectively applied in forest fire prevention and commanding system, especially in fire monitor and position. After explaining the significance of scientific planning of fire-tower, this paper analyzes GIS`s functions in building forest fire prevention system. This paper uses case study method, which designs a model, fire tower planning and analysis, based on MapGIS platform. Afte...

Casting Silica at Room Temperature Silica cannot be used with traditional molding techniques because of its very high melting temperature. In addition, conventional grinding and polishing processes limit how small and complex the silica micro-optics can be. Geltech overcame these problems by developing methods to cast net-shape (no grinding necessary) silica-glass micro-optics at room temperatu...

This paper describes the creative process behind an artwork that combines and projects data in sculptural ways. This projection comes in the form of a reimagined magic lantern device called the Magic Lantern Horror Vacui Data Projector. This device is the result of collaborative glass art and electronic art techniques. Central to the projection system are re-envisaged glass magic lantern slides...

Eu(3+)-doped transparent glass ceramics containing In(2)O(3) nano-crystals were prepared by melt quenching and subsequent heating. X-ray diffraction analysis, transmission electron microscope observation, and photoluminescence excitation spectra demonstrated that In(2)O(3) nano-particles sized 3-6 nm homogenously distributed among the glass matrix. Under excitation of these nano-particles, Eu(3...
