چکیده
It has been shown that a 32-bit logarithmic arithmetic unit can operate faster than, and maintain the accuracy of, a 32-bit floating point unit. It uses the logarithmic number system (LNS), in which a real number is represented as a fixedpoint logarithm. In this paper we investigate the implementation of three fast affine projection (FAP) algorithms using LNS. We propose a simplified Conjugate Gradient FAP (SCGFAP) algorithm. We show that the 32-bit or 20-bit LNS implementation of the CGFAP and the SCGFAP algorithm are superior to those of the classical FAP algorithm.

The influence of cork oak pruning on the yield and growth of cork
Bearing in mind the importance of pruning as a silvicultural treatment in cork oak (Quercus suber L.) open woodland of the dehesa type, an experiment was designed to assess the effect of pruning on cork yield. This work was carried out in two ways: synchronically, comparing pruned sites with others which were either unpruned or pruned at different times, and diachronically, comparing pruned and...
متن کاملMorphological Segmentation of Remotely Sensed Forest Covers in High Spatial Resolution Images
In this paper novel algorithms developed to automatically segment forest cover types are presented. The digital image analysis followed is mainly based on mathematical morphology operators and exploits the textural features in high spatial resolution images. These input images consist of true colour digital orthophotos and the studied forest covers consist of the main occurrences in Portugal: o...
متن کاملImproved malignant melanoma prognosis at a consultant-delivered multidisciplinary pigmented lesion clinic in Cork.
Early detection and excision is the only effective treatment for malignant melanoma. To assess the effect of a consultant-delivered, rapid-access pigmented lesion clinic (PLC) established at the South Infirmary-Victoria University Hospital (SIVUH), we analyzed melanoma tumour-stage prior to (1998-2002) and after (2003-2007) the advent of the PLC. Patients attending SIVUH had a greater proportio...
متن کاملBayesian Classification for Inspection of Industrial Products
In this paper, a real time application for visual inspection and classification of cork stoppers is presented. Each cork stopper is represented by a high dimensional set of characteristics corresponding to relevant visual features. We have applied a set of non-parametric and parametric methods in order to compare and evaluate their performance for this real problem. The best results have been a...
متن کاملCork taint of wines: role of the filamentous fungi isolated from cork in the formation of 2,4,6-trichloroanisole by o methylation of 2,4,6-trichlorophenol.
Cork taint is a musty or moldy off-odor in wine mainly caused by 2,4,6-trichloroanisole (2,4,6-TCA). We examined the role of 14 fungal strains isolated from cork samples in the production of 2,4,6-TCA by O methylation of 2,4,6-trichlorophenol (2,4,6-TCP). The fungal strains isolated belong to the genera Penicillium (four isolates); Trichoderma (two isolates); and Acremonium, Chrysonilia, Clados...
