Effective mass (m*) is defined as: where x, y, z are the directions in the reciprocal Cartesian space (2π/A), En(k) is the dispersion relation for the n-th electronic band. The explicit form of the ...

Abstract: To model the responses of borehole electromagnetic sensing in complicated geological environments, the geometric multigrid preconditioned finite-difference frequency-domain (FDFD) method is ...

In this work, a finite volume formulation developed for two-dimensional models is extended to deal with axisymmetric models of heat conduction applications. This formulation uses a vertex centered ...

Electric fields generated by the motion of ocean waves through the Earth’s ambient geomagnetic fields and the induced secondary magnetic field can be observed at the seafloor and at the sea-surface, ...

What Are FEM, FDM and FVM? FEM, FDM and FVM differ from one another in important ways. Understanding these distinctions is key to selecting the method most appropriate for your purposes. The ...

Atmospheric aerosol particles cool Earth’s climate by serving as cloud droplet seeds. This cooling effect represents both the single most uncertain and the largest negative radiative forcing. Cloud ...

Asymmetric Electrostatic Force is a very interesting phenomenon. The intensity of the electrostatic force that acts on a charged asymmetric shaped conductor changes when the direction of the electric ...

Turbulence in fluid flows is universal, from galactic scales generated by supernova explosions down to an aggressively stirred cup of coffee. There is no debate that turbulence is important, yet no ...

An abrupt transition to turbulence occurs in a large variety of situations, ranging from the formation of spiral galaxies, to the fluid motion in the atmosphere and oceans, to flows over aeroplane ...
