Once thought of being useful primarily for planning the location of telecommunication antennas, it has become clear in the meantime that three-dimensional city models are of importance in their own right. This paper presents some of our latest results on the reconstruction of building models from laser scanning DSM’s and digital ground plans. First, we show how buildings can be reconstructed fr...

The purpose of this study was to describe biomechanical parameters of head, upper and lower body extremities during a straight right punch throw related to performance and injury mechanism. Subjects were eight elite right-handed male (age 20.4 ± 2.1yrs height 177.4 ± 8.5 cm mass 70.4 ± 16.8 kg) amateur boxers. 3D motion analysis was used to assess the kinematics of the right side extremities ...

A straight skeleton of a polygon or of a polytope is a piecewise linear skeletal structure that partitions the underlying object by means of a self-parallel shrinking process. We propose a method for constructing different straight skeletons for a given nonconvex polytope Q in 3-space. The approach is based on so-called bisector graphs on the sphere, and allows for generating straight skeletons...

The purpose of this study was to develop new and modified tools that allow HDR brachytherapy quality assurance tests to be carried out efficiently without film, video cameras, stopwatches, and mechanical rulers; and to devise methods that use these new tools for daily and quarterly check procedures, which are efficient and provide increased accuracy compared to previous methods. The HDR brachyt...

Given a nite set L of lines in the plane we wish to compute the zone of an additional curve in the arrangement A(L), namely the set of faces of the planar subdivision induced by the lines in L that are crossed by , where is not given in advance but rather provided on-line portion by portion. This problem is motivated by the computation of the area bisectors of a polygonal set in the plane. We p...

THE FOOD AND DRUG ADMINISTRATION (FDA) REcently announced another Advisory Panel scheduled to meet in July 2010 to consider whether or not to remove rosiglitazone from the market. Central to the discussion will be the results of a recently published cardiovascular outcomes trial that randomized patients to receive rosiglitazone or alternative diabetes therapies, the RECORD trial. On February 20...

ytoplasmic structures are sites of active mammalian mRNA decay, according to Cougot et al. (page 31). The group had previously identified cytoplasmic foci that included two human mRNA decapping enzymes. They now add subunits of a deadenylase, exonuclease, and possible helicase to the list of proteins found at these sites. After inhibition of a 5 –3 exonuclease, poly(A) RNA accumulates at the sa...
