We present a technique for the illustrative rendering of 3D line data at interactive frame rates. We create depth-dependent halos around lines to emphasize tight line bundles while less structured lines are de-emphasized. Moreover, the depth-dependent halos combined with depth cueing via line width attenuation increase depth perception, extending techniques from sparse line rendering to the ill...

this paper studies the role of the conceptual models of the policy makers in the quality of prioritizing problems in the agenda setting stage of public policy cycle.  several factors contribute to perceiving problems, presenting clear definitions of them, prioritizing them and then problem setting in the format of agenda for policy makers. however, expecting to examine the theories of enactment...

Assessment is considered as one of the fundamental elements in the field of foreign language acquisition. In order for communication take place, adequate number of vocabulary is needed to be known by the learners. The salient role of vocabulary in the field of foreign language acquisition resulted in the publication of several hundreds of papers and dozens of books. Due to the dominant role of ...

with the growth of technology, supervising systems are increasingly replacing humans in military, transportation, medical, spatial, and other industries. among these systems are machine vision systems which are based on image processing and analysis. one of the important tasks of image processing is classification of images into desirable categories for the identification of objects or their sp...

We analyze the behavior of a fragile material reinforced by a reticulated elastic unbreakable structure in the case of antiplane shear. The microscopic geometry of this material is described by means of two small parameters: the period ε of the grid and the ratio δ between the thickness of the fibers and the period ε. We show that the asymptotic behavior as ε → 0 and δ → 0 depends dramatically ...
