We turn high energy elastic scattering of hadrons into an initial value problem using an evolution equation based on the Regge Field Theory, which has a form of the complex nonlinear reaction-diffusion equation, with time being played by the logarithm of energy. The initial conditions are ...
simultaneous equations- a set of equations in two or more variables for which there are values that can satisfy all the equations simultaneously equation- a mathematical statement that two expressions are equal Based on WordNet 3.0, Farlex clipart collection. © 2003-2012 Princeton University, Far...
As a consequence of their different ionic radii, the three cations (Mg2+, Nb5+ and Ti4+) on the B-site of the perovskite structure generate chemical heterogeneous nanoregions for minimizing the elastic energy. These regions are the nucleus of the PNRs, which are frozen (quenched) at ...

By introducing the reduced elastic stiffnesses (4.14.39)aαβ=sαβ−sα3s3β/s33 for α, β=1,2,6 the first equation may be written as (4.14.40)ɛα=aαβσβ The symmetry properties of sαβ obviously carry over to aαβ, which is also positive definit...
For an elastic solid, the strain generated is proportional to the magnitude of the stress. One simple way of applying a stress on a solid is to apply two collinear, equal and opposite forces on two equal areas on the opposite sides of a rectangular bar. If the forces face each other, ...
could be defined as the division of engineering science which deals with the behaviour of the fluid in both motion and rest situations. fluid mechanics is one of the four divisions of mechanics namely quantum mechanics, relative mechanism, fluid mechanics and elastic body mechanics. fluid ...
Here, u is the longitudinal displacement potential for which ∇ × ∇u = 0. The first term is the longitudinal or compression wave and the second term describes the shear wave. In general, an elastic wavefield is composed of both compression and shear waves. In order to simplify the pro...
Paralleling the analysis of Trégourès and van Tiggelen for multiple scattering of acoustic waves in heterogeneous elastic media, we derive a quantum field formulation of the dynamics of deformation in static granular ensembles in which the total wave energy satisfies a Schrdinger-like equation. An...
