In this study, we have investigated radius dependence of hydrogen storage within armchair (n,n) single walled carbon nanotubes (SWCNT) in a square arrays. To this aim, we have employed equilibrium molecular dynamics (MD) simulation. Our simulations results reveal that radius of carbon nanotubes are an important and influent factor in hydrogen distribution inside carbon nanotubes and consequentl...

BACKGROUND Paramedic education has evolved in recent times from vocational post-employment to tertiary pre-employment supplemented by clinical placement. Simulation is advocated as a means of transferring learned skills to clinical practice. Sole reliance of simulation learning using mannequin-based models may not be sufficient to prepare students for variance in human anatomy. In 2012, we tria...

In this article we present an optimal Markov Decision-based Call Admission Control (MD-CAC) policy for the multimedia services that characterize the next generation of wireless cellular networks. A Markov decision process (MDP) is used to represent the CAC policy. The MD-CAC is formulated as a linear programming problem with the objectives of maximizing the system utilization while ensuring cla...

Abstract In order to study the effects of coarse grain size and Ni content on mechanical properties, molecular dynamics (MD) simulation nanocrystalline (NC) Ni-W alloys with bimodal structure is carried out. The NC samples are established by embedding into fine matrix. solute atoms in segregated boundary affected zone (GBAZ) through severe plastic deformation (SPD). uniaxial tensile shows that ...

Discovering the functional mechanisms of biological systems frequently requires information that challenges the spatial and temporal resolution limits of current experimental techniques. Recent dramatic methodologi-cal advances have made all-atom molecular dynamics (MD) simulations an ever more useful partner to experiment because MD simulations capture the atomic resolution behavior of biologi...

have also given a linear time algorithm to determine the set of possible root locations for a minimum diameter shortest path tree, and shown that any minimum diameter tree must pass through this region. When compared with the 1-Steiner algorithm, minimum diameter A-trees produced lower maximum and average delays, with slightly higher tree length. Consideration of the feasible center region resu...
