Software development for embedded systems clearly transcends traditional "programming" and requires intimate knowledge of hardware, as well as deep understanding of the underlying application that is to be implemented.
Our complex world is characterized by representation, transmission, and storage of information - and information is mostly processed in digital form. With the advent of DSPs (digital signal processors), engineers are able to implement complex algorithms with relative ease. Today we find DSPs all around us - in cars, digital cameras, MP3 and DVD players,… (More)
A new coding scheme based on the scalar-vector quantizer (SVQ) is developed for compression of medical images. The SVQ is a fixed rate encoder and its rate-distortion performance is close to that of optimal entropy-constrained scalar quantizers (ECSQs) for memoryless sources. The use of a fixed-rate quantizer is expected to eliminate some of the complexity… (More)
Vitamin E and C are well-known antioxidant vitamins. Oxidative stress is common in chronic kidney diseases. We evaluated 43 dialysis subjects prospectively in a cross-sectional survey. Serum vitamin E concentration was checked in all subjects; 37 cases underwent blood sampling for measurement of serum vitamin C. The enrolled subjects consisted of 12 (27.9%)… (More)
