In ad-hoc network such as inter-vehicle communication (IVC) system, safety applications that vehicles broadcast the information such as car velocity, position and so on periodically are considered. In these applications, if there are many vehicles...
ITS(Intelligent Transport Systems)とは,先進の情報通信技術を用いて道路·車·人が一体となったシステムを実現することにより,道路交通の安全性,輸送効率,快適性の向上などを目指したシステムである.このITS専用の路車間通信としてDSRC(Dedicated Short Range Communication)がある.本稿では,このDSRCの応用技術として,高速移動する車に対して車両位置に特化した情報提供を行うプッシュ型情報配信アプリ...
We propose a general prediction method based on the efficient computation and online update of the Singular Value Decomposition (SVD) of historical data. The SVD is fundamental to many data modeling algorithms, but the traditional methods for comp...
