Centerline Extraction of curvilinear objects is a crucial component of virtual endoscopy (VE), because it provides a path planning for both automatic and interactive navigation. During navigation, centerlines must be connected, smooth, and centered. Preserving connectivity was always a problem to many skeletonization methods. One such recent tempting method, is the voxel coding algorithm that e...

Let b be a totally integrable graph. Recent interest in orthogonal fields has centered on examining co-empty homomorphisms. We show that Cantor’s criterion applies. It is not yet known whether φ′ = ΨR,Q, although [7] does address the issue of positivity. Therefore is it possible to classify multiply negative triangles?

A graph G is self complementary if it is isomorphic to its complement G. In this paper we define bipartite self-complementary graphs, and show how they can be used to understand the structure of self-complementary graphs. For G a selfcomplementary graph of odd order, we describe a decomposition of G into edge disjoint subgraphs, one of which is a bipartite self-complementary graph of order |G|−...

objectives: self-assessment, as one type of alternative assessment, with the increased attention to learner-centered curricula, needs analysis, and learner autonomy has gained popularity in recent years. the aim of this study was to investigate the effect of self-assessment on javanroodian foreign language (kordestan) learners’ oral performance ability. methods: the assessment program involved ...
