Simultaneous embedding of planar graphs is related to the problems of graph thickness and geometric thickness. Techniques for simultaneous embedding of cycles have been used to show that the degree-4 graphs have geometric thickness at most two [3]. Simultaneous embedding techniques are also useful in visualization of graphs that evolve through time. The notion of simultaneous embedding is relat...

Good geometrical calibration is essential in the use of high resolution detectors. The individual sensors in the detector have to be calibrated with an accuracy better than the intrinsic resolution, which typically is of the order of 10μm. We present an effective method to perform fine calibration of sensor positions in a detector assembly consisting of a large number of pixel and strip sensors...

Brand, L., 1979. Field and laboratory studies on the Coconino Sandstone (Permian) vertebrate footprints and their paleoecological implications. Palaeogeogr., Palaeoclimatol., Palaeoecol., 28: 25-38. The fossil footprints in the Coconino Sandstone have long been considered to be evidence for eolian deposition. I conducted field study of the fossil footprints in Hermit Basin, the Grand Canyon, an...

The objectives of this study were 1) to describe the technical requirements of different tracks where classifying points are disputed for the Olympics as the European continent tracks (E), world championship competitions tracks (W), and Olympic Games track - Beijing, 2008- (O); and 2) to compare and establish differences or similarities between the three previous contexts. The sample used for t...
