Along with the rapid development of advanced driving assistance systems for intelligent vehicles, essential functions such as forward collision warning and collaborative cruise control need to detect relative positions surrounding vehicles. This paper proposes a planar localization system based on ultra-wideband (UWB) ranging technology. Three UWB modules are installed top each vehicle. Because...

objective(s): dispersive liquid-liquid microextraction coupled with gas chromatography (gc)-flame ionization detector was developed for the determination of valproic acid (vpa) in human plasma. materials and methods: using a syringe, a mixture of suitable extraction solvent (40 µl chloroform) and disperser (1 ml acetone) was quickly added to 10 ml of diluted plasma sample containing vpa (ph, 1.0...

This paper presents a method for relative orientation using the feature based matching techniques. The interest operator and feature based matching are use to select points and measure parallax for relative orientation automatically. After the feature based matching, a fine least square matching is preformed to achieve high precision. The matched points are then used for the relative orientatio...

Two independent wind profiles were measured every hour during Februa j 1986 with a five-beam, UHF (405 MHz) wind Profiler at Platteville, Colorado. Our analysis of the horizontal wind components over all heights for the entire month gave a standard deviation of about 1.3 m s-' for the measurement errors one can expect for three-beam Profilers in clear air. This study demonstrated that it is imp...

State of the art A/D converters are still critical in power-sensitive, battery-operated equipment like hearing aids. In this article, a new approach is presented that features excellent signal quality, 85 dB dynamic range equivalent to a 15-bit output word, 16 kHz sampling rate, 25 μW power consumption, and 0.54 mm2 chip area. Compared to standard components, the enormous power savings result f...

This paper considers the problem of maximizing an expectation function over a finite set, or finite-arm bandit problem. We first propose naive stochastic algorithm for obtaining probably approximately correct (PAC) solution to this discrete optimization in relative precision, that is which solves up error smaller than prescribed tolerance, with high probability. also adaptive provides PAC-solut...
