“Hyper-redundant” robots have a very large or infinite degree of kinematic redundancy. This paper develops new methods for determining “optimal” hyper-redundant manipulator configurations based on a continuum formulation of kinematics. This formulation uses a backbone curve model to capture the robot’s essential macroscopic geometric features. The calculus of variations is used to develop diffe...

Several syntactic methods have been constructed to automate theorem proving in first-order logic. The positive (negative) hyper-resolution and the clause tableaux were combined in a single calculus called hyper tableaux in [1]. In this paper we propose a new calculus called hyperS tableaux which overcomes substantial drawbacks of hyper tableaux. Contrast to hyper tableaux, hyperS tableaux are e...

Meta-heuristics such as simulated annealing, genetic algorithms and tabu search have been successfully applied to many difficult optimization problems for which no satisfactory problem specific solution exists. However, expertise is required to adopt a metaheuristic for solving a problem in a certain domain. Hyper-heuristics introduce a novel approach for search and optimization. A hyper-heuris...

In this paper, a shell fitting space (SFS) is presented to map non-linearly separable data to linearly separable ones. A linear or quadratic transformation maps data into a new space for better classification, if the transformation method is properly guessed. This new SFS space can be of high or low dimensionality, and the number of dimensions is generally low and it is equal to the number of c...

hyper ige syndrome (hies) is a rare primary immunodeficiency disease. most of hies cases are sporadic. hies type ad is caused by mutation in signal transducer and activator of transcription-3 (stat-3). a number of mosaicism hies has been reported that is associated with intermediate phenotype. autosomal recessive hies (ar-hies) is due to mutation in dock-8 or cytokine sis 8 and tyk2 or tyrosine...

background: asthma is a multifactorial disease and its severity varies with the inflammatory grade. there are conflicting reports about the roles of trace elements in asthma. this study examined the effects of zinc (zn), copper (cu), and selenium (se) concentrations in sera of patients with allergic asthma attending ghaem hospital, mashhad, iran. methods: forty-nine patients, aged 10 to 50 year...
