چکیده
(2R,3R)-2,3-Diaminobutane-1,4-diol 6 and its dibenzyl ether 7 were efficiently synthesized starting from L-tartaric acid 1a. The crucial step, debenzylation of intermediate dibenzyloxydiazide 4, was accomplished in good yield by boron trichloride–dimethyl sulfide complex. The enantiomeric series was similarly obtained starting from D-tartaric acid. c 1997 Elsevier Science Ltd

Segmentation and reconstruction of on-line handwritten scripts
On-line handwritten scripts consist of sequences of components that are pen tip traces from pen-down to pen-up positions. This paper presents a segmentation and reconstruction procedure which segments components of a script into sequences of static strokes, and then reconstructs the script from these sequences. The segmentation is based on the extrema of curvature and in ection points in indivi...
متن کاملNumerical optimisation in spot detector design
Spots are image details resulting from objects, the projections of which are so small that the inner structure of these objects cannot be resolved from their image. Spot detectors are image operators aiming at the detection and localisation of spots in the image. Most spot detectors can be tuned with parameters. This paper addresses the problem of how to select the parameters. We propose to use...
متن کاملGenerating parallel programs from skeleton based specifications
The Static Iterative Transformation Speciication System (SITSS) is a portable parallel programming system. This paper describes the techniques used in SITSS to generate parallel programs from user speciications of algorithms. The paper rst outlines SITSS, the algorithmic skeleton on which SITSS is based, and the user interface. The techniques for analysing the speciication selecting a data part...

This paper presents an expert system for differential diagnosis of erythemato-squamous diseases incorporating decisions made by three classification algorithms: nearest neighbor classifier, naive Bayesian classifier and voting feature intervals-5. This tool enables doctors to differentiate six types of erythemato-squamous diseases using clinical and histopathological parameters obtained from a ...
