To probe the microscopic balance of forces close to a moving contact line, the boundary conditions around viscous drops sliding down an inclined plane are investigated. At first, the variation of the contact angle as a function of the scale of analysis is discussed. The dynamic contact angle is measured at a scale of 6 mum all around sliding drops for different volumes and speeds. We show that ...

Modeling and simulation of nonlinear systems under chaotic behavior is presented. Nonlinear systems and their relation to chaos as a result of nonlinear interaction of different elements in the system are presented. Application of chaotic theory for power systems is discussed through simulation results. Simulation of somemathematical equations, e.g. Vander Pol’s equation, Lorenz’s equation, Duf...

Abstract: Effects of aspect ratio, sweep angle, and stacking sequence of laminated composites were studied to find the optimized configuration of an aeroelastically tailored composite wing idealized as a flat plate in terms of flutter speed. The aeroelastic analysis has been carried out in frequency-domain. The 2D finite element analysis in conjunction with Doublet-lattice Method (DLM) has been...

In this paper, we introduce a goodness of fit test for expo- nentiality based on Lin-Wong divergence measure. In order to estimate the divergence, we use a method similar to Vasicek’s method for estimat- ing the Shannon entropy. The critical values and the powers of the test are computed by Monte Carlo simulation. It is shown that the proposed test are competitive with other tests of exponentia...

This research aims to investigate the effect of conservative reporting on the investors' opinion divergence at the time of earnings announcement in a 5 year period during 2012-2016; the required data have been collected from Tehran Securities and Stock Exchange Organization and the population is consisted of 585 corporates-years which have been selected by the systematic removal sampling. To in...

It has been well observed that the horizontal component of magnetic field at photosphere changes rapidly and irreversibly after solar eruptions. Specifically, near polarity inversion line increases substantially, while center decreases. Such a phenomenon is considered as dynamic feedback from corona to photosphere, but underlying mechanism remains in debate. Here based on recent magnetohydrodyn...

Abstract The density evolution behaviour and distribution characteristics of the explosively formed reactive material jet were studied based on SPH algorithm. Numerical simulations show that has obvious expansion phenomenon under shaped charge effect. Especially, divergence head are obvious. In general, deficit occurs in whole jet, increases from to tail. Compared with initial liner material, d...

We demonstrate that the efficiency of ion transmission from atmosphere to vacuum through stainless steel electrodes that contain slowly divergent conical duct (ConDuct) channels can be close to 100%. Here, we explore the properties of 2.5-cm-long electrodes with angles of divergence of 0°, 1°, 2°, 3°, 5°, 8°, 13°, and 21°, respectively. The ion transmission efficiency was observed to jump from ...
