A novel dynamic link architecture based on multiscale morphological dilation-erosion is proposed for frontal face authentication. Instead of a set of Gabor lters tuned to diierent orientations and scales, mul-tiscale morphological operations are employed to yield a feature vector at each node of the reference grid. Linear projection algorithms for feature selection and automatic weighting of th...
this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
As a way to emphasize several distinct features of the mul-tiresolution methods based on wavelets, we describe connections between the multiresolution LU decomposition, multigrid and multiresolution re-duction/homogenization for self-adjoint, strictly elliptic operators. We point out that the multiresolution LU decomposition resembles a direct multigrid method (without W-cycles) and that the al...
abstract: research purpose: the purpose of this research is to identify academic databases assessment factors and criteria at law and political science majors. the necessity of this research is to distinguish academic databases assessment factors and criteria and to identify the most important ones and rank them in order to select an appropriate database according to students’ and faculty memb...
A MUL-tree is a generalization of a phylogenetic tree that allows the same leaf label to be used many times. Lott et al. [9,10] recently introduced the problem of inferring a so-called consensus MUL-tree from a set of conflicting MUL-trees and gave an exponential-time algorithm for a special greedy variant. Here, we study strict and majority rule consensus MUL-trees, and present the first ever ...
the following null hypothesis was proposed: h : there is no significant difference between the use of semantically or communicatively translates scientific texts. to test the null hypothesis, a number of procedures were taken first, two passages were selected form soyrcebooks of food and nutrition industry and gardening deciplines. each, in turn, was following by a number of comprehension quest...
in this paper, the nonlinear free vibrations of thin symmetric and non-symmetric cross-ply composite plates subjected to biaxial initial stresses are investigated. because of their excellent properties such as specific strength and specific stiffness, composite plates have wide applications in aerospace and mechanical structures. based on von-karman's strain-displacement relations and using gal...
126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
this study was an attempt to investigate the effect of subtitling on vocabulary learning among iranian intermediate students. to find the homogeneity of the groups, tofel test was administered to student in kish mehr institute in garmsar. after analyzing the data, 60 participants (female students) who scored within the range of one standard deviation above and below the mean, were selected as h...
