The Online Electric Vehicle (OLEV) is an innovative electric transportation system developed by the Korea Advanced Institute of Science and Technology (KAIST), Daejon, Korea, which remotely picks up electricity from power transmitters buried underground. Unlike a conventional electric vehicle that requires significant recharging downtime, the battery in the(More)
In this paper the recent progress of the wireless charging electric transportation system developed at Korea Advanced Institute of Technology (KAIST) called On-Line Electric Vehicle (OLEV) is introduced. The system architecture and mathematical model describing the cost issue of the OLEV based public transportation system are presented. The OLEV is the(More)
This paper introduces widely used current automated material handling systems in thin-film-transistor liquid-crystal-display (TFT-LCD) panel manufacturing systems. The automated material handling system (AMHS) in this paper refers to a hardware system that transports discrete parts from one processing machine to another. The TFT-LCD panel industry has been(More)
In this paper, we present an analysis to identify a sensor location for an inertial measurement unit (IMU) on the body of a skier and propose the best location to capture turn motions for training. We also validate the manner in which the data from the IMU sensor on the proposed location can characterize ski turns and performance with a series of(More)
Sports fans are able to watch games from many locations using TV services while interacting with other fans online. In this paper, we identify the factors that affect sports viewers' online interactions. Using a large-scale dataset of more than 25 million chat messages from a popular social TV site for baseball, we extract various game-related factors, and(More)
This paper presents an initial investment cost analysis of public transportation systems operating with wireless charging electric vehicles (EVs). There are three different types of wireless charging systems, namely, stationary wireless charging (SWC), in which charging happens only when the vehicle is parked or idle, quasi-dynamic wireless charging (QWC),(More)
