Mathematical analogies in physics. Thin-layer wave theory
Thin layer Electromagnetism Viscoelasticity Reflection and transmission coefficient
2015/8/17
Field theory applies to elastodynamics, electromagnetism, quantum mechanics, gravitation and other similar fields of physics, where the basic equations describing the phenomenon are based on constitut...
Theory of localized bipolar wave-structures and nonthermal particle distributions in the auroral ionosphere
localized bipolar wave-structures nonthermal particle distributions auroral ionosphere
2009/11/13
Bipolar wave structures and nonthermal particle distributions measured by the FAST satellite in regions of downward current are interpreted in terms of the nonlinear evolution of a two-stream instabil...
Dissipation and wave-ion interaction in the solar wind:Links between fluid and kinetic theory
wave-ion interaction solar wind Links between fluid and kinetic theory
2009/11/13
In this paper we establish links between turbulence dissipation and wave-particle interactions in the solar corona and wind. Based on quasilinear theory, a set of anisotropic, multi-component fluid eq...
A theory of the Earth's magnetic field and of sunspots,based on a self-excited dynamo incorporating the Hall effect
Earth's magnetic field self-excited dynamo Hall effect
2009/11/12
A new viewpoint on the generation and maintenance of the Earth's magnetic field is put forward, which integrates self-exciting dynamo theory with the possibility of energy coupling along orthogonal ax...
Calculation of the parameter deflection in a new theory of the Earth’s magnetic field
parameter deflection new theory Earth’s magnetic field
2009/11/12
In a recent paper on the theory of the Earth's magnetic field and key features of Sunspot activity (de Paor, 2001), a central role in the calculation of secular variations of the geomagnetic field was...
On the mean-field theory of the Karlsruhe Dynamo Experiment
Dynamo geodynamo dynamo experiment mean-field dynamo theory a-effect
2009/11/12
In the Forschungszentrum Karlsruhe an experiment has been constructed which demonstrates a homogeneous dynamo as is expected to exist in the Earth's interior. This experiment is discussed within the f...
On resonant interactions of ions with plasma waves in a reduced quasi-linear theory
resonant interactions of ions plasma waves reduced quasi-linear theory
2009/11/12
Based on quasi-linear theory (involving pitch angle scattering), the resonant interactions between ions and waves in an anisotropic multi-component plasma are discussed. In particular, electromagnetic...

Hall effect energy transfer mechanism Earth’s magnetic field and sunspots
2009/11/12
Clarification is offered of the energy transfer role played by the Hall effect in a recent paper: de Paor, A., A theory of the Earth's magnetic field and of sunspots, based on a self-excited dynamo in...
Theory and observation of double discontinuities
Theory observation double discontinuities
2009/11/11
Recent research using high-resolution magnetic field data to examine the interior structures of MHD shocks in interplanetary space and in the magnetotail led to a surprising discovery that a slow-mode...
Exact theory for localized envelope modulated electrostatic wavepackets in space and dusty plasmas
Exact theory localized envelope electrostatic wavepackets space and dusty plasmas
2009/11/9
Abundant evidence for the occurrence of modulated envelope plasma wave packets is provided by recent satellite missions. These excitations are characterized by a slowly varying localized envelope stru...
Turning the resistive MHD into a stochastic field theory
resistive MHD stochastic field theory
2009/11/2
Classical systems stirred by random forces of given statistics may be described via a path integral formulation in which their degrees of freedom are stochastic variables themselves, undergoing a mult...
Detecting spatial patterns with the cumulant function–Part 1:The theory
spatial patterns cumulant function The theory
2009/10/30
In climate studies, detecting spatial patterns that largely deviate from the sample mean still remains a statistical challenge. Although a Principal Component Analysis (PCA), or equivalently a Empiric...

Extending the Similarity Theory for Atmospheric Boundary Layers: Contribution from Background Stratification
Atmospheric boundary layer similarity theory turbulence stratification effects
2009/6/10
The structure of the atmospheric boundary layer has traditionally been described using only surface fluxes and the Coriolis parameter. We review here the proposal of Kitaigorodskii (1988) and Kitaigor...
