In this paper, we present a vision-based vehicle detection method for collision warning of driver assistance system on highway in the nighttime. The major function of our work is to find preceding vehicles in the dynamic background. The system captures the image of road environment by a camera mounted on the windshield of the test car and uses multi-level(More)
This paper describes the fault diagnosis in the operation of industrial ball bearings. In order to cluster the very small differential signals of the four classic fault types of the ball bearing system, the chaos synchronization (CS) concept is used in this study as the chaos system is very sensitive to a system's variation such as initial conditions or(More)
It has recently been shown that a combined input output queued (CIOQ) switch with a speedup factor of 2 can exactly emulate an output-queued (OQ) switch [1]-[6]. In particular, the maximal matching algorithm, named Least Cushion First/Most Urgent First (LCF/MUF) algorithm presented in [6], can be executed in parallel to achieve exact emulation. However, the(More)
In this paper, an active-clamp forward converter with a current-doubler circuit for photovoltaic (PV) energy conversion is proposed. The proposed converter consists of a PV arrays energy source, a active-clamp forward converter, and a current-doubler circuit. It has the following advantages: 1) maximum power point tracking (MPPT) can be accomplished for PV(More)
