This paper presents global and point-wise comparisons of experimental measurements and numerical simulation results of electro-osmotically driven flows in two elementary micro-channel configurations, a straight channel with a groove and a T-junction channel. The microchannels are made by photolithography using poly-dimethylsiloxane (PDMS), a type of silicon product, which is transparent, and el...

This paper presents a numerical matrix method based on Bernstein polynomials (BPs) for approximate the solution of a system of m-th order nonlinear Volterra integro-differential equations under initial conditions. The approach is based on operational matrices of BPs. Using the collocation points,this approach reduces the systems of Volterra integro-differential equations associated with the giv...

 Numerous problems in engineering and science can be converted into optimization problems. Artificial bee colony (ABC) algorithm is a newly developed stochastic optimization algorithm and has been widely used in many areas. However, due to the stochastic characteristics of its solution search equation, the traditional ABC algorithm often suffers from poor exploitation. Aiming at this weakness o...

We present evaluations of two-dimensional surface current fields based on quantitative comparisons of satellite images with numerical model results provided by the German Federal Maritime and Hydrographic Agency (BSH). Earlier studies have shown that multisensor data can be used to derive sea surface. However, a quantitative evaluation of the resulting vector fields is difficult, due to the low...

Ant Algorithm is a newly developed random bionics algorithm in recent years. The paper firstly introduces Ant Algorithm into the structural optimization. Three numerical examples have been presented. They are solved by Ant Algorithms, Genetic Algorithm and Simulated Annealing Algorithm and so on .The comparisons between them have been obtained in terms of efficiency and effectiveness. It must b...

In this paper, natural frequency and response of forced vibration of composite laminated conical shells under different boundary conditions are investigated. To this end, equations of Donnell's thin shell theory are used as governing equations. The analytical Galerkin method together with beam mode shapes as weighting functions is employed to solve the problem. Due to importance of boundary con...
