Recently, power consumption of server computers is one of the most important topics. Although DVS (Dynamic Voltage Scaling) can reduce power consumption, this method is only used at idle time or low load computation time, generally. In this paper, we propose a task scheduling algorithm for reducing power consumption especially at high load computation time.(More)
In development of inter-vehicles communication (IVC) systems, simulation technologies are very essential to verify the correctness of protocols. We focus on a model of radio wave propagation for IVC simulation systems and approximate the model. As a land mobile communication model, we adopt Kaji model. In our model, a distance between vehicles, a building(More)
Various origami works are published as origami drill books in which a sequence of folding operations with simple diagrams is described. However, the book readers often give up following the instruction of the book halfway because it is too difficult to understand a way to fold in accordance with the diagrams. Therefore, we have developed an operational(More)
