Linear programming algorithms have been widely used in Decision Support Systems. These systems have incorporated linear programming algorithms for the solution of the given problems. Yet, the special structure of each linear problem may take advantage of different linear programming algorithms or different techniques used in these algorithms. This paper proposes a web-based DSS that assists dec...

Parallelizing sparse simplex algorithms is one of the most challenging problems. Because of very sparse matrices and very heavy communication, the ratio of computation to communication is extremely low. It becomes necessary to carefully select parallel algorithms , partitioning patterns, and communication optimization to achieve a speedup. Two implementations on Intel hypercubes are presented i...

Communication between human and hearing impair persons is very difficult in daily life. Sign language interpretation system can translate signs into text or voice for solving this problem. In practically, however, it is not convenient because it cannot be carried by the signer. It is better if the hearing impair persons can bring the sign language interpretation with themselves all the times su...

Abstract. A sign-linear one bit map from the d-dimensional sphere S to the n-dimensional Hamming cube H = {−1,+1}n is given by x 7→ {sign(x · zj) : 1 ≤ j ≤ n} where {zj} ⊂ S. For 0 < δ < 1, we estimate N(d, δ), the smallest integer n so that there is a sign-linear map which has the δ-restricted isometric property, where we impose normalized geodesic distance on S, and Hamming metric on H. Up to...

Road sign recognition is one of the core technologies in Intelligent Transport Systems. In the current study, a robust and real-time method is presented to identify and detect the roads speed signs in road image in different situations. In our proposed method, first, the connected components are created in the main image using the edge detection and mathematical morphology and the location of t...

This is a Social integration of the deaf and dump people. They people communication media only finger of hand movement, they are interact with each other of hand movement but normal people doesn’t communicate with deaf and dump people because the normal people can’t undusted language of sign. This cause the isolation of deaf people in the society. In this paper a method of image capturing and f...
