The Catmull-Clark subdivision algorithm consists of an operator that can be decomposed into a refinement and a smoothing operator, where the refinement operator splits each face with m vertices into m quadrilateral subfaces and the smoothing operator replaces each internal vertex with an affine combination of its neighboring vertices and itself. In this paper, we generalize the Catmull-Clark sc...

brusellosis is one of the most dangerous infectious zoonotic diseases which at present affect most areas of iran directly or indirectly.the aim of the present study was evaluate the efficacy of pcr test in detection of brucellosis. suspected animal sera (n=20) to brusellosis were collected from clinics and subjected to rose bengal and wright agglutination tests and to pcr analysis. while 6 samp...

We present a formal description of the planning algorithm used in the Prodigy4.0 system. The algorithm is based on an interesting combination of backward-chaining planning and simulation of plan execution. The backward-chainer selects goal-relevant operators, and then Prodigy simulates their application to the current state of the world. The system can use di erent backward-chaining procedures,...

brucellosis is an endemic disease in our country. neurobrucellosis occurs in 5 to 10% of cases, and can present at any stage of of the disease. this study was undertaken to evaluate clinical, epidemiological and paraclinical aspects of brucellosis with and without neurological manifestations. data of 30 patients, 15 cases with nervous system involvement (neurobrucellosis) and 15 cases without n...
