Two distinct redistribution grids - adaptation techniques, spring analogy and elliptic grid generator are applied to two-dimensional steady, inviscid, shocked flows, and the ability of each technique is examined and compared. Euler equations are solved base on Roe's Reimann solver approach to simulate supersonic flow around a sphere, transonic flow about an airfoil and supersonic flow in a symm...

In this report, I present a simple model using springs to conceptualize the relationship between ionic conductances across a cellular membrane and their effect on membrane potential. The equation describing the relationships linking membrane potential, ionic equilibrium potential, and ionic conductance is of similar form to that describing the force generated by a spring as a function of its di...

Absorbing sound almost completely at specific frequencies with conventional acoustic materials whose thickness is least 60 times smaller than the wavelength a challenge, particularly low frequencies. Fort this purpose, metamaterials are of great interest. Here, metamaterial called multi-pancake cavities. It composed main pore repetition thin annular cavities (pancake cavities). Previous researc...

This paper introduces a new pedagogical tool using haptic feedback and visual analogy, to improve perception and learning of nanoscale phenomena, for people without prior knowledge of nanophysics. This tool is a haptic and virtual-reality simulator of a foremost onedimensional nanophysical phenomenon: the approach-retract cycle of an Atomic Force Microcope (AFM) probe, with a force-feedback dev...

Architectural design inspired by nature is one of the conventional methods in architectural design, but different types of the influence of nature on architectural design are not well studied yet. In spite of the importance of the type of inspiration, there is not a significant research about the relation of this method with other methods of architectural creation, nor about the correct way of ...

We study the existence and stability of periodic solutions of a canonical mass-spring model of electrostatically actuated micro-electro-mechanical system (MEMS) by means of classical topological techniques like a-priori bounds, Leray-Schauder degree and topological index. A saddle-node bifurcation is revealed, in analogy with the autonomous case.
