In this paper, the development of a semiactive suspension control of quarter car model using fuzzy-based controller has been done. The quarter car model to be used here can be described as a nonlinear two degrees of freedom system which is subject to excitation from different road profile. The semi-active control is designed as the fuzzy control inferred by using two single input rule fuzzy mod...

A novel model is developed to evaluate the van der Waals (vdW) interactions between a capsule shaped bacterium (P. putida) and flat minerals plates in different approach profiles: Vertically horizontally. comparison of approaches well-developed spherical particle mineral surface (semi-infinite wall spherical) has been made this investigation. The interaction potentials for capsule-shaped are fo...

colza (canola) is a crop with high rate of grain loss during harvesting. at harvest, semi-dried grains of canola’s pods are either opened or dropped due to mechanical impacts. therefore, lots of grains drop before entering combine head. another obstacle to successful harvest of canola is that ripe grain's pods are twisted together. this results in heavy grain loss at dividers of combine pi...

We compute the ground state energy of a massive scalar field in the background of a cylindrical shell whose potential is given by a delta function. The zero point energy is expressed in terms of the Jost function of the related scattering problem, the renormalization is performed with the help of the heat kernel expansion. The energy is found to be negative for attractive and for repulsive back...

In this paper, the passive control of flow past a semi-circular cylinder is investigated. This control is achieved by adding a porous medium between the solid obstacle and the incompressible fluid in order to reduce drag forces and regularize the flow. A vortex-penalization method is chosen to easily model the flow in the different media. Several configurations of the porous layer are investiga...

In this paper, effects of EHD actuators on hydrodynamic behavior and heat transfer of air flow over a circular cylinder were considered. Pressure and temperature distributions around the cylinder were measured in presence of wire-plate EHD actuators. The Reynolds number based on cylinder diameter (d) were 3500, 7000. Experiments were performed for various configurations. Based on obtained resul...

Based on a recent generalization of Bloch's theorem, we present Bloch ansatz for the Harper model with an arbitrary rational magnetic flux in various geometries, and solve associated equations analytically. In case cylinder particular boundary condition, find that energy spectrum edge states has no dependence length cylinder, which allows us to construct quasi-one-dimensional theory is exact de...
