Well-posedness of the fully coupled quasi-static thermo-poro-elastic equations with nonlinear convective transport [PDF]

, 2018
This paper is concerned with the analysis of the quasi-static thermo-poroelastic model. This model is nonlinear and includes thermal effects compared to the classical quasi-static poroelastic model (also known as Biot's model).

General procedure to initialize the cyclic soil water balance by the Thornthwaite and Mather method [PDF]

, 2010
The original Thornthwaite and Mather method, proposed in 1955 to calculate a climatic monthly cyclic soil water balance, is frequently used as an iterative procedure due to its low input requirements and coherent estimates of water balance components ...

Slowing Down of Neutrons in Infinite Homogeneous Media [PDF]

, 1957
We have derived from the Boltzmann equation a new integral equation governing the slowing down of neutrons in a homogeneous mixture of atoms. The new equation reflects a view of the neutrons as propagating down the energy scale, whereas the Boltzmann ...

A mesoscopic approach to diffusion phenomena in mixtures [PDF]

, 2005
The mesosocpic concept is applied to the theory of mixtures. The aim is to investigate the diffusion phenomenon from a mesoscopic point of view. The domain of the field quantities is extended by the set of mesoscopic variables, here the velocities of the

Macroscopic Balance Equations [PDF]

, 2001
A balance equation accounts for changes in an extensive quantity (such as mass or energy) that occur in a well-defined region of space, called the control volume (CV). The control volume is set off from its surroundings by boundaries, called control surfaces (CS). These surfaces may coincide with real surfaces, or they may be mathematical abstractions,

Stringy Probe Particle and Force Balance [PDF]

, 1999
We directly derive the classical equation of motion, which governs the centre of mass of a test string, from the string action. In a certain case, the equation is basically same as one derived by Papapetrou, Dixon and Wald for a test extended body.

Bohmian trajectories and the Path Integral Paradigm. Complexified Lagrangian Mechanics

, 2008
David Bohm shown that the Schr{\"o}dinger equation, that is a "visiting card" of quantum mechanics, can be decomposed onto two equations for real functions - action and probability density.

New Kinetic Equation for Pair-annihilating Particles: Generalization of the Boltzmann Equation [PDF]

, 1999
A convenient form of kinetic equation is derived for pair annihilation of heavy stable particles relevant to the dark matter problem in cosmology. The kinetic equation thus derived extends the on-shell Boltzmann equation in a most straightforward way ...

Transport theory with nonlocal corrections [PDF]

, 1998
A kinetic equation which combines the quasiparticle drift of Landau's equation with a dissipation governed by a nonlocal and noninstant scattering integral in the spirit of Snider's equation for gases is derived.
