Special Theory of Relativity through the Doppler Effect
We present the special theory of relativity taking the Doppler effect as the starting point, and derive several of its main effects, such as time dilation, length contraction, addition of velocities,…

Coherent thermodynamical modelling of geomaterial reinforced by wires
The TexSol is a composite geomaterial : a sand matrix and a wire network reinforcement. For small strains a thermodynamical continuous model of the TexSol including the unilaterality of the wire…

Three methods for the description of the temporal response to a SH plane impulsive seismic wave in a soft elastic layer overlying a hard elastic substratum
We treat the case of a flat stress-free surface (i.e., the ground in seismological applications) separating air from a homogeneous, isotropic, solid substratum overlain by a homogeneous, isotropic,…

Nonequilibrium Approach to Bloch-Peierls-Berry Dynamics
We examine the Bloch-Peierls-Berry dynamics under a classical nonequilibrium dynamical formulation. In this formulation all coordinates in phase space formed by the position and crystal momentum…

Poincare's relativistic Doppler-Fizeau formula
We deduce from Poincare's ellipsoidal wavefronts a relativistic Doppler-Fizeau formula that is not the same as 1905 Einstein's one. Longitudinally, Einstein's formula and Poincare's…

Radiation enhancement and radiation suppression by a left-handed metamaterial
The perfect lens property of a dispersive and lossy left-handed metamaterial (LHM) disk is exploited to superimpose a source of electromagnetic radiation onto its mirror image, formed as a result of…

Wave Equation for Fractal Solid String
We use the fractional integrals to describe fractal solid. We suggest to consider the fractal solid as special (fractional) continuous medium. We replace the fractal solid with fractal mass dimension…

Connecting Blackbody Radiation, Relativity, and Discrete Charge in Classical Electrodynamics
It is suggested that an understanding of blackbody radiation within classical physics requires the presence of classical electromagnetic zero-point radiation, the restriction to relativistic…

Excitation of surface dipole and solenoidal modes on toroidal structures
The time dependent Schrodinger equation inclusive of curvature effects is developed for a spinless electron constrained to motion on a toroidal surface and subjected to circularly polarized and…

Chaotic Emission from Electromagnetic Systems Considering Self-Interaction
The emission of electromagnetic waves from a system described by the Hénon-Heiles potential is studied in this work. The main aim being to analyze the behavior of the system when the damping term is…

Vibrational dynamics of confined granular material
By means of two-dimensional contact dynamics simulations, we analyze the vibrational dynamics of a confined granular layer in response to harmonic forcing. We use irregular polygonal grains allowing…

Comment on "Gauge transformations are Canonical transformations"
We comment on the work of Tai L Chow, Eur. J. Phys. 18, 467 (1997). By considering the Lagrangians which are uniquely defined only to within an additive total time derivative of a function of…

Stationary solutions and Neumann boundary conditions in the Sivashinsky equation
New stationary solutions of the (Michelson) Sivashinsky equation of premixed flames are obtained numerically in this paper. Some of these solutions, of the bicoalescent type recently described by…

Delayed Choice Between Purely Classical States
It is argued that Wheeler's insightful idea of delayed choice experiments may be explored at a classical level, arising naturally from number-theoretical conjugacies always necessarily present in…

On the vector solutions of Maxwell equations with the spin-weighted spherical harmonics
The discussion of our recent work concerning the vector solution of boundary-value problems in electromagnetism is extended to the case of no azimuthal symmetry by means of the spin-weighted…

On the Solution of Maxwell's First Order Equations
In an attempt to solve Maxwell's first order system of equations, starting from a given initial state, it is found that a consistent solution depending on the temporal evolution of the sources…

The clock paradox in a static homogeneous gravitational field
The gedanken experiment of the clock paradox is solved exactly using the general relativistic equations for a static homogeneous gravitational field. We demonstrate that the general and special…
