Floorplanning is one of the most important steps in the physical design. Traditional floorplanning focuses on minimizing wirelength and area. As design complexity grows, more and more nets need to be routed in a chip, which makes routing difficulty increase dramatically in modern ICs. Hence, it is necessary to consider net routability during floorplanning. This paper proposes the first work to consider...
This paper introduces the representation of generalized dominance-based decision tables by neighborhood systems. Dominance-based rough set approach (DRSA) introduced by Greco et al. is a useful tool for multi-criteria data analysis problems. Recently, Dembczynski et al. introduced the concept of generalized decisions as a generalization of the DRSA where criteria in a decision table may be assigned...
We present an analysis of the efficiency and radiation pattern of the textured-surface LED by tracing the light rays that emits from the active layer. Through simulation, we discover that the efficiency depends on the thickness of the textured layer and its separation distance from the active layer. By carefully choosing these two parameters, maximum efficiency an be achieved. The radiation pattern...
