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...

Introduction Since the first phased array design, the overlap decoupling became the most often used decoupling technique. At a certain amount of overlap, the mutual inductance between adjacent array coil elements is forced to be zero. Therefore the interaction between neighbouring coil elements is eliminated [1]. The hole-slotted coil design has been shown to provide a deeper RF penetration int...

OBJECTIVE To validate the usefulness of a diffusional anisotropic capillary array phantom and to investigate the effects of diffusion tensor imaging (DTI) parameter changes on diffusion fractional anisotropy (FA) and apparent diffusion coefficient (ADC) using the phantom. MATERIALS AND METHODS Diffusion tensor imaging of a capillary array phantom was performed with imaging parameter changes, ...

In this paper, an optimal approach to design wideband tapped-delay line (TDL) array antenna is proposed. This approach lets us control the array angular and frequency response over a wide frequency band. To this end, some design restrictions are defined and a multi-objective optimization problem is constructed by putting the individual restrictions together. The optimal weights of the TDL proce...

A proper factor u of a string y is a cover of y if every letter of y is within some occurrence of u in y. The concept generalises the notion of periods of a string. An integer array C is the minimal-cover (resp. maximal-cover) array of y if C [i] is the minimal (resp. maximal) length of covers of y[0 . . i], or zero if no cover exists. In this paper, we present a constructive algorithm checking...

The benefits and challenges of highly parallel array coils for head imaging were investigated through the development of a 3T receive-only phased-array head coil with 96 receive elements constructed on a close-fitting helmet-shaped former. We evaluated several designs for the coil elements and matching circuitry, with particular attention to sources of signal-to-noise ratio (SNR) loss, includin...

Some level{2 and level{3 Distributed Basic Linear Algebra Subroutines (DBLAS) that have been implemented on the Connection Machine system CM{200 are described. No assumption is made on the shape or size of the operands. For matrix{matrix multiplication , both the nonsystolic and the systolic algorithms are outlined. A systolic algorithm that computes the product matrix in{place is described in ...

Human mortality data sets can be expressed as multiway data arrays, the dimensions of which correspond to categories by which mortality rates are reported, such as age, sex, country and year. Regression models for such data typically assume an independent error distribution or an error model that allows for dependence along at most one or two dimensions of the data array. However, failing to ac...

Partial shading reduces the power output of solar modules, generates several peak points in P-V and I-V curves and shortens the expected life cycle of inverters and solar panels. Electrical array reconfiguration of PV arrays that is based on changing the electrical connections with switching devices, can be used as a practical solution to prevent such problems. Valuable studies have been perfor...
