Cropping is a cutting process whereby opposing aligned blades create a shearing failure by exerting opposing forces normal to the surfaces of a metal sheet or plate. Building on recent efforts to quantify cropping, this paper formulates a plane strain elastic–plastic model of a plate subject to shearing action by opposing rigid platens. Shear failure at the local level is modeled by a cohesive ...

In this study, the missile staging process by implementing a side-injected jet is simulated numerically. The problem is considered to be axisymmetric and the thin shear layer approximation of Navier-Stokes equations along with an algebraic turbulence model is used in a quasi-static form for the calculations. The free stream corresponds to a very high altitude flight condition with a Mach number...

This paper presents an overview of active array antennas, system-level nonlinear effects in such antennas, and their modeling and simulation techniques. Influence of nonlinear distortions and interference in active antennas on the overall system performance is considered. Modeling and simulation techniques, which can be applied to active array antennas, are substantially different from those us...

a book review is presented on numerical simulation of groundwater flow and solute transport, edited by l. elango, published by allied publishers pvt. ltd. in 2005, 245 pp, hardback isbn 81-7764-923-x.

In this paper, the benefit of numerical simulation for the development of a special crystal growth technique for the processing of silicon wafers for photovoltaic applications on an industrial scale is demonstrated, as an example for the importance of numerical simulation for industrial processing of bulk semiconductor crystals in general. Depending on the complexity of the problems to be treat...

Presently, the characterization of metal materials is becoming increasingly important due to the development of new materials, which is often performed numerically. Therefore, the accuracy of software simulation totally depends on the quality of the constitutive models and of their parameters. Hence, in this work, it is performed a loading path which allows to attain the most unique and disting...

Orthogonal Frequency Division Multiplexing (OFDM) is considered to be a promising technique against the multipath fading channel for wireless communications. One of the disadvantages of OFDM is peak to average power ratio (PAPR) problem. In this paper, we analyze a PAPR reduction system which combines a selected mapping technique (SLM) and a deliberate clipping technique. The numerical analysis...

In this paper, we deal with the pricing of power options when the dynamics of the risky underling asset follows the double stochastic volatility with double jump model. We prove efficiency of our considered model by fast Fourier transform method, Monte Carlo simulation and numerical results using power call options i.e. Monte Carlo simulation and numerical results show that the fast Fourier tra...
