Sensor-based smart spaces have been developed to help caring of the elderly. Selection of sensors, layout of smart space, design of fusion algorithms, and knowledge of domain experts are critical to the development of a useful ICT system for caring the elderly in the institutional facilities. We apply multi-modal sensor fusion technique to improve the confidence level of our system, and leverage the...
We report on the experimental demonstration of a novel n-channel GaN epilayer RESURF GaN MOSFET with good trade-off between breakdown voltage and specific on-resistance for the first time. Device with 4 mum channel length and 16 mum RESURF length has breakdown voltage up to 730 V with specific on-resistance 34 mOmega-cm2 (VG-VT=20 V).
An efficient way for computing the response of an adaptive digital filter is to use sliding-block distributed arithmetic (SBDA). One disadvantage of distributed arithmetic is the amount of memory utilized. By encoding the memory tables in offset binary code (OBC), the size of the memory tables is reduced in half. However, the computational workload remains unchanged. By modifying the computational...
This paper presents a new method to automatically grade pathological prostate images according to Gleason grading system. Two feature extraction methods were proposed based on fractal dimension to analyze the variations of intensity and texture complexity in images. Each image can be classified into appropriate grade by using Bayes classifier and k-Nearest-Neighbor (k-NN) classifier, respectively...
