To facilitate more natural interaction with robots, we have been investigating an approach for generating descriptions of objects in a scene, using point cloud models built with the Scale Invariant Feature Transform (SIFT). The 3D models are constructed from 24 images taken from different viewing angles. For each recognized object, the model is placed into an internal representation of the envi...
OBJECTIVE Seed filling in view lattice is a method for accelerating volume rendering. Our previously published results on using seed filling had the limitation that they did not support cut planes. Cut planes are one of the main advantages of using volume rendering over surface rendering. In this article we describe the seed-filling acceleration technique and propose two fast reseeding processe...
the purpose of this study was to investigate iranian efl learners’ beliefs about the role of rote learning (rl) in vocabulary learning strategies; besides, the study examined if english proficiency would influence learners’ vocabulary learning strategy use. this study addresses the need for a clear understanding of the role of rl in efl vocabulary learning by looking at iranian efl learners’ ow...
the village of Connihatty, Zillah Kajshahye, and presents the following peculiar malforraities:? (a.) Spine.?An angulo-lateral curvature is seen occupying the whole of the dorsal region; the lateral deflexion is towards the right; all the ribs from the 3rd downwards participate in the curve, and are greatly bent at their angles. (b.) Hands (1) Right.?Fingers normal, but the metacarpal bone of t...
In the title mol-ecule, C(15)H(18)O(2)S, the dimethyl-cyclo-hexa-diene unit is slightly non-planar, having a folded conformation with the two double-bond planes forming a dihedral angle of 3.9 (6)°. Methyl groups of the dimethyl-cyclo-hexa-diene ring tilt away from each other, forming inter-nal C-C-C(Me) angles approximately 11° greater than the exterior angles.
In the title compound, C(29)H(22)Br(2)O(3), the dihedral angles between the mean planes of the benzene rings within each biphenyl group are 26.7 (8) and 30.9 (8)°. The mean planes of the terminal and inner benzene rings of the biphenyl groups bonded through a propan-1-one group in the V-shaped mol-ecule are oriented at angles of 66.1 (7) and 60.0 (8)°, respectively. The two Br atoms are opposit...
abstract recent studies suggest that prelistening activities play an important role in the development of listening comprehension (e.g. long 1990;chiang and dunkel 1992; schmidt-rinehart 1994; jensen and hansen 1995; robinson et al., 1995; buck, 1995; foster and skehan,1996; teng 1996; robinson, 2001; chang and read 2006). in line with previous studies and to shed light on a new aspect of sche...
Cardiac myofibers are organized into laminar sheets about four cells thick. Recently, it has been suggested that these layers coincide with the plane of maximum shear during systole. In general, there are two such planes, which are oriented at +/-45 degrees to the main principal strain axes. These planes do not necessarily contain the fiber axis. In the present study, we explicitly added the co...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
BACKGROUND Various medical fields rely on detailed anatomical knowledge of the distal radius. Current studies are limited to two-dimensional analysis and biased by varying measurement locations. The aims were to 1) generate 3D shape models of the distal radius and investigate variations in the 3D shape, 2) generate and assess morphometrics in standardized cut planes, and 3) test the model's cla...
