A design and analysis of a novel proximity-fed printed slot antenna with 3.5/5.5 GHz dual band-notched characteristics are presented. To obtain an ultra-wideband (UWB) response, a circular patch with a rectangular conjunction arm is etched concentrically inside a ground plane aperture. The antenna is proximity-fed by a microstrip line with an open shunt stub on the other side of the substrate. ...

Different slot structures have been widely used in numerous designs to produce antennas with enhanced bandwidths. In this paper, a printed slot antenna has been introduced as a candidate for use in the multi-band wireless communication applications. The antenna slot structure has a rectangular shape with its width, from the side of feed, has been modified in the form of Koch fractal curve of th...

Slot die coating technology is a function of the coating process, auxiliary system and fundamental technique. The decision to utilize a coating technology needs to be analyzed against these functions to determine best fit. In the era of clean, thin and precise converting operations, a customized coating system is necessary to have a technical edge. Building the system from the material up to th...

This demonstration describes ScriptEase II, a tool that allows game story authors to generate scripts that control objects in video games by manipulating high level story patterns and game objects. ScriptEase II can generate scripting code for any game engine for which a translator is written. Currently there are translators for Neverwinter Nights and real Pinball games. Story Creation With Scr...
