in this paper energy bands and berry curvature of graphene was studied. desired hamiltonian regarding the next-nearest neighbors obtained by tight binding model. by using the second quantization approach, the transformation matrix is calculated and the hamiltonian of system is diagonalized. with this hamiltonian, the band structure and wave function can be calculated. by using calculated wave f...
Objective: to demonstrate the effectiveness of combination of radial extracorporeal shock wave therapy and muscle energy technique on pain, range of motion, and neck function of the individuals with active trigger points of upper trapezius muscle. Method: Fifty-four (54) participants with active TrPs of upper trapezius muscle were participated and randomly divided into three groups. Group A (...
Peristaltic transport of an incompressible electrically conducting viscous fluid in an inclined planar asymmetric channel is studied. The asymmetry is produced by choosing the peristaltic wave train on the walls to have different amplitude and phase. The closed form solutions of momentum and energy equation in presence of viscous dissipation term are obtained for long wave length and low Reynol...
We study the pairing of Fermi gases near the d-wave Feshbach resonance. Using Nozieres and Schmitt-Rink potential that produces the two –body energy Scattering amplitude, we have obtained an analytic solution of the gap equation and ground states by minimizing of energy at .
When entering the field of wave energy utilization it is relevant to ask—why is it important to start utilizing this resource? The reasons for this are shared with other renewable energy sources, such as hydro, wind, solar, biomass and other ocean energy forms such as tidal, currents, thermal and salinity driven systems. The key issues that the use of renewable energy sources can help to overco...
advantages and disadvantages of using “stokes parameters” in exploration of inertia-gravity wave properties are discussed in this paper. the survey is carried out on an inertia-gravity wave event (igws in what follows) that occurred over iran from 7 to 9 february 2012. applying this technique for investigation of atmospheric igws was recommended by vincent and fritts (1987) and then developed b...
Many hope that ocean waves will be a source for clean, safe, reliable and affordable energy, yet wave energy conversion facilities may affect marine ecosystems through a variety of mechanisms, including competition with other human uses. We developed a decision-support tool to assist siting wave energy facilities, which allows the user to balance the need for profitability of the facilities wit...
semidiscrete finite element approximation of a hyperbolic type integro-differential equation is studied. the model problem is treated as the wave equation which is perturbed with a memory term. stability estimates are obtained for a slightly more general problem. these, based on energy method, are used to prove optimal order a priori error estimates.
The fundamental solution of the system of differential equations in bio-thermoelasticity with dual phase lag (DPL) in case of steady oscillations in terms of elementary function is constructed and basic property is established. The tissue is considered as an isotropic medium and the propagation of plane harmonic waves is studied. The Christoffel equations are obtained and modified with the ther...
