effective elastic properties for carbon nanotube reinforced composites are obtained through a variety of micromechanics techniques. an embedded carbon nanotube  in  a  polymer  matrix  and  its surrounding  interphase  is  replaced with an equivalent fiber for  predicting  the  mechanical  properties of  the  carbon  nanotube/polymer composite. the effects of an interphase layer between the nan...

Symmetric positive semi-definite (SPSD) matrix approximation methods have been extensively used to speed up large-scale eigenvalue computation and kernel learning methods. The standard sketch based method, which we call the prototype model, produces relatively accurate approximations, but is inefficient on large square matrices. The Nyström method is highly efficient, but can only achieve low a...

sustained release oral delivery systems are designed to achieve therapeutically effective concentrations of drug in the systemic circulation over an extended period of time. the purpose of the present investigation was to design and evaluate sustained release matrix tablets of nifedipine, a poorly water soluble drug, employing hydroxypropyl methyl cellulose ( hpmc) and ethyl cellulose ( ec) as ...

Discrete body of revolution (DBOR) codes can accelerate moment method (MoM) solutions for scattering geometries possessing discrete circular symmetry. Traditional DBOR formulations require modifications to the incident field, such as decomposition into circular modes. While appropriate for methods employing direct solvers, approaches employing iterative solvers are disadvantaged by this dramati...

Matrix transpose is a fundamental matrix operation that arises in many scientific and engineering applications. Communication is the main bottleneck in performing matrix transpose on most multiprocessor systems. In this paper, we focus on torus interconnection networks and propose application-level routing techniques that improve load balancing, resulting in better performance. Our basic idea i...

The paper is concerned with the study of magneto-thermoelastic interactions in three dimensional thermoelastic medium under the purview of three-phase-lag model of generalized thermoelasticity. The medium under consideration is assumed to be homogeneous orthotropic medium. The fundamental equations of the three-dimensional problem of generalized thermoelasticity are obtained as a vector-matrix ...

Abstract The notion of a nonequilibrium heat capacity is important for bio-energetics and calorimetry active materials more generally. It centers around the excess or work dissipated during quasistatic relaxation between different conditions. We give exact results random walks moving in an energy landscape on graph, based calculations employing matrix-tree matrix-forest theorems. That graphical...
