The paper deals with the object recognition problem. The objective is to localize and recognize the known objects in different orientations on cluttered background. As a learning tool we choose support vector machines (SVMs). To eliminate the problem caused by cluttered background we organize the image pixels in tree structures, which enable us to deal only with the object pixels. Both, oneand ...
This paper proposes a query classification system for a one-click search system that uses feature vectors based on snippet similarity. The proposed system targets the NTCIR-10 1CLICK-2 query classification subtask and classifies queries in Japanese and English into eight predefined classes by using support vector machines (SVMs). In the NTCIR-9 and NTCIR-10 tasks, most participants used complex...
Given a complex manifold X, a normal crossing divisor D ⊂ X whose irreducible components D 1 ,. .. , D s are smooth, and a choice of natural numbers r = (r 1 ,. .. , r s), we construct a manifold X(D, r) with an action of a torus Γ and we prove that some full subcategory of the category of Γ-equivariant vector bundles on X(D, r) is equivalent to the category of parabolic vector bundles on (X, D...
leishmaniasis has long been known as a significant public health challenge in many parts of iran. phlebotomus papatasi and p. sergent i are the vectors of zoonotic cutaneous leishmaniasis and anthroponotic cutaneous leishmaniasis respectively, and 5 species of sand flies including p. kandelakii , p. neglectus , p. perfiliewi , p. keshishiani and p. alexandri are considered as probable vectors...
introduction: hematopoietic stem cells are always in a quiescence state. since they need retroviral transduction to infect dividing cells, they are resistant to retrovirus transduction. they need to be pre-stimulated by a cytokine cocktail. for proliferation without maturation, we suggest mip-1α as a novel factor. material and methods: retroviral vector produced by pg13/ln c8 cells titter on he...
in this paper, a useful classification of all lie subalgebras of a given lie algebraup to an inner automorphism is presented. this method can be regarded as animportant connection between differential geometry and algebra and has many applications in different fields of mathematics. after main results, we have applied this procedure for classifying the lie subalgebras of some examples of lie al...
