Statistical Indicators of Stock Assessed as a Percentage of GDP, and Consequences of Abusing the Logic of Statistical Thinking

SAVOIU, Gheorghe - In: Romanian Statistical Review Supplement 62 (2014) 1, pp. 51-57

The macroeconomic indicators concern both the flows that are not fully or partially compensated over a time interval, which can be cumulated or integrated, and the stocks or funds identified in a particular moment. These indicators are addressed either as free real and nominal indicators, or as...

Entropy production in Cu–Fe–Ni alloys — The bi-velocity method

Wierzba, Bartek - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 1, pp. 56-61

The bi-velocity method allows quantitative description of the complex diffusion mass transport process for an unlimited number of elements. The method deals with (1) composition dependent diffusivities, (2) different partial molar volumes of components, (3) the stress field during the diffusion...

Segregation in multicomponent mixtures under gravity: The bi-velocity method

Wierzba, Bartek; Danielewski, Marek - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 12, pp. 2325-2332

The bi-velocity concept of separation of diffusion and drift flows allows one to combine the convection and dissipative contributions to the mass and energy fluxes. It is shown that the bi-velocity method combined with statements of the first law of thermodynamics and the Euler’s and Liouville...

Stochastic continuity equation and related processes

Bassi, Gabriele; Bazzani, Armando; Mais, Helmut; … - In: Physica A: Statistical Mechanics and its Applications 347 (2005) C, pp. 17-37

We consider the processes defined by a Langevin equation and the associated continuity equation. The average of the … density function, solution of the continuity equation, satisfies the Fokker–Planck equation. For a volume preserving vector … that, for a volume preserving vector field, any power of the density function satisfies the same continuity equation with …

Real processing IV. The derivation of the Navier–Stokes equation from the principle of minimal deformation

Reiser, Bernhard - In: Physica A: Statistical Mechanics and its Applications 291 (2001) 1, pp. 512-522

As a special case of the general principle of minimal entropy production discussed in earlier parts of this series, we relate here the hydrodynamic Navier–Stokes equation including its non-linear term, to the minimisation of ∫∑i(∇vi)2dV, for fixed boundaries. The connection is made...
