We derive a JPEG compliant image compressor which is based on hierarchical vector quantization (HVQ). The goal is to reduce complexity while increasing compression speed. For each block, the DCT DC coefficient is encoded in the regular way while the residual is mapped through HVQ to a pre-computed bit-stream corresponding to the compressed DCT AC coefficients. Approximation quality is generally...

This paper examines how stock prices are affected by research and development activities for Danish firms for the period, 1989 to 2002. Both through analysis of portfolios and regression analysis, the role of R&D assets is considered along with a number of other fundamental factors, such as size, the book to market ratio, leverage and the CAPM beta. There is at best a weak indication that R&D i...

Failure, the lack of technical and commercial success for a product in the marketplace, is endemic to innovative technologies. Failure is worthy of study if only to better understand success. Historians of business and technology accept this, but tend to focus more on success. This lack of coverage distorts our knowledge of the business process because failure is an integral, if not dominant, t...
