in this paper, a new enhanced version of the particle swarm optimization (pso) is presented. an important modification is made by adding probabilistic functions into pso, and it is named probabilistic particle swarm optimization (ppso). since the variation of the velocity of particles in pso constitutes its search engine, it should provide two phases of optimization process which are: explorati...

Existing methods extract facial expression parameters from captured expressions data in two steps. First, head absolute orientation is acquired, the captured expression is then transferred from world coordinates to local coordinates. Second, expression parameters are extracted from local coordinate data. However, above methods results to severe error accumulation. In the second step, the error ...

in this article, multiple-product pvrp with pickup and delivery that is used widely in goods distribution or other service companies, especially by railways, was introduced. a mathematical formulation was provided for this problem. each product had a set of vehicles which could carry the product and pickup and delivery could simultaneously occur. to solve the problem, two meta-heuristic methods...

ganoderma lucidum is one of the most well-known fungi, and has many applications in medicine. ganoderic acid is among the valuable secondary metabolites of ganoderma lucidum, and responsible for the inhibition of the tumor cell growth and cancer treatment. application of ganoderic acid has been limited because of low yields of its production from ganoderma lucidum. the present study aims to inv...

We introduce a code generator that converts unoptimized C++ operating on sparse data into vectorized and parallel CPU or GPU kernels. Our approach unrolls the computation massive expression graph, performs redundant elimination, grouping, then generates an architecture-specific kernel to solve same problem, assuming sparsity pattern is fixed, which common scenario in many applications computer ...

Background: Breast cancer is one of the most prevalent malignancies among women in various countries. HER2 overexpression, which is due to different reasons, occurs in 20-30% of breast cancers. HER2 gene encodes an 185kDa transmembrane glycoprotein with 1255 amino acids. This active product triggers downstream intracellular signaling pathways inducing cell proliferation and cell survival. These...
