In this paper, a collocation method for solving high-order linear partial differential equations (PDEs) with variable coefficients under more general form of conditions is presented. This method is based on the approximation of the truncated double exponential second kind Chebyshev (ESC) series. The definition of the partial derivative is presented and derived as new operational matrices of der...

On-orbit servicing space robot is one of the challenging applications in space robotic field. Main task of the on-orbit space robot involves the tracking, the grasping and the positioning of a target. The dynamics in operational space is useful to achieve such tasks in Cartesian space. The operational space dynamics is a formulation of the dynamics of a complex branching redundant mechanism in ...

Abstract—In this paper, we address the problem of recovering complex-valued signals from a set of complex-valued linear measurements. Approximate message passing (AMP) is one state-ofthe-art algorithm to recover real-valued sparse signals. However, the extension of AMP to complex-valued case is nontrivial and no detailed and rigorous derivation has been explicitly presented. To fill this gap, w...

educational organizations due to entry new competitors in this field, they are drawing a long-term vision for them. in order to achieve an acceptable point in this field, should be internal and external factors including of the challenges and potentials of the accelerator and the opportunities, and also examines the opportunities and then attempt to formulate the optimum strategies. in this pap...

This paper presents a methodology for operational and economic characteristics based evaluation and selection of a power plant using Graph theoretic approach. A universal evaluation index on the basis of Operational and economics characteristics of a plant is proposed which evaluates and ranks the various types of power plants. The index thus obtained from the pool of operational characteristic...

In this paper , the concept of the partition anti-circulant matrix on skew field is given,and its operational properties is discussed. Mathematics Subject Classification: 15A24

to assess the microbiological status of a biofiltration system used to treat borehole water, filtermatrix samples were analyzed after staining for the presence of active biofilms using confocal laser scanningmicroscopy (clsm). clsm revealed the presence of biofilms on the filter matrix with actively metabolizingmicrobial cells present. thereafter, heterotrophs,manganese oxidizing bacteria (mob)...

The growth of intelligence-led policing has placed even greater emphasis on the clear identification of crime hotspots as well as the choice of the crime reduction or detection strategy identified to combat a problem. Crime hotspots are becoming central to policing strategy in many locations, as they enable an operational commander to focus resources into the areas of highest need. This paper o...
