This investigation examines all-optical multicast routing in wavelength-routed optical networks with sparse Multicast Capable (MC) nodes that have three phases. The first phase is the MC node placement, and the maximum path count first (MPCF) algorithm is utilized to obtain candidates for MC nodes. The second phase is a multicast routing with MC-based schemes which including two algorithms, nam...

This paper is intended to provide a numerical algorithm based on random sampling for solving the linear Volterra integral equations of the second kind. This method is a Monte Carlo (MC) method based on the simulation of a continuous Markov chain. To illustrate the usefulness of this technique we apply it to a test problem. Numerical results are performed in order to show the efficiency and accu...

In most of the cases, the experimental study of Nanotechnology involves high cost for Laboratory set-up and the experimentation processes were also slow. So, one cannot rely on experimental nanotechnology alone. As such, the Computer-Based molecular simulations and modeling are one of the foundations of computational nanotechnology. The computer based modeling and simulations were also referred...

We present a methodology for the identification of transport parameters for Gallium Nitride (GaN) based semiconductor materials and devices. A Monte Carlo (MC) approach has been employed to investigate the electron transport in GaN and AlGaN, materials that are very important in device applications of high-power, high-frequency electronics. Our model is validated against measured data and compa...

In this paper, a low complexity and efficient multi-user Space Time Block Code Multi-Carrier Code Division Multiple Access (STBC MC-CDMA) for downlink wireless communication system is proposed. STBC MC-CDMA provides diversity gain to improve transmission efficiency of mobile wireless systems where both STBC encoder and decoder are in time domain thus reducing the complexity at the receiver side...

One of the drawback of multicarrier code division multiple access (MC CDMA) is the high peak to average power ratio (PAPR). In this paper A novel scheme based on pulse shaping described for PAPR reduction. Here three different pulse shaping filters (Raised cosine, Sinc power pulse and Nyqist pulse) are described for PAPR reduction in MC CDMA system. The method is based on the proper selection o...

The distortion of structure of a simple, inverse-12, soft-disk fluid undergoing two-dimensional plane Couette flow was studied by nonequilibrium molecular dynamics (NEMD) simulation and by equilibrium Monte Carlo (MC) simulation with a nonequilibrium potential, under which the equilibrium structure of the fluid is that of the nonequilibrium fluid. Extension of the iterative predictor-corrector ...

Numerical studies have been performed to interpret the observed “shock overtaking magnetic cloud (MC)” event by a 2.5 dimensional magnetohydrodynamic (MHD) model in heliospheric meridional plane. Results of an individual MC simulation show that the MC travels with a constant bulk flow speed. The MC is injected with very strong inherent magnetic field over that in the ambient flow and expands ra...

We present preliminary results for the charm quark mass mc and the D and Ds mesons decay constants fD and fDs from a lattice QCD calculation with Nf = 2 dynamical fermions. We use the twisted mass fermionic action defined at maximal twist so that physical quantities are automatically O(a) improved. Two lattice spacings are considered. The charm quark mass has been renormalised in the RI-MOM sch...

Abstract. A new Modular Marx Multilevel Converter, MC, is presented. The MC topology was developed based on the Marx Generator concept and can contribute to technological innovation for sustainability by enabling wind energy off-shore modular multilevel power switching converters with an arbitrary number of levels. This paper solves both the DC capacitor voltage balancing problem and modularity...
