In a convex drawing of a plane graph, all edges are drawn as straight-line segments without any edge-intersection and all facial cycles are drawn as convex polygons. In a convex gr...
In this paper, consistency is understood in the standard way, i.e. as the absence of a contradiction. The basic constructive logic BK c4 , which is adequate to this sense of consis...
This paper presents the incorporation of a new internal force for active contours. This internal force is generated by an electric charge, distributed all-over the active contour....
Undeniable signatures were proposed to limit the public verification property of ordinary digital signature. In fact, the verification of such signatures cannot be obtained withou...
