A Simple Throw Model for Frontal Vehicle-Pedestrian Collisions
This paper discusses a simple theoretical throw model for frontal vehicle-pedestrian collisions. The model is based on the simple assumption that pedestrian movement after impact can be approximated…

Full-wave finite-difference time-domain simulation of electromagnetic cloaking structures
This paper proposes a radial dependent dispersive finite-difference time-domain method for the modelling of electromagnetic cloaking structures. The permittivity and permeability of the cloak are…

Time dilation and Langevin paradox
The principle of invariance of the velocity of light is only valid for the wrong measurements of inertial observers who ignore their own movement and consider themselves at rest. The Langevin (or…

Time desynchronization and Ehrenfest paradox
One of the kinematical effects that give raise to the principle of relativity is time desynchronization of moving clocks. The detailed analysis of this phenomenon is of great importance for leading…

Floating Bodies of Equilibrium in Three Dimensions. The central symmetric case
Three-dimensional central symmetric bodies different from spheres that can float in all orientations are considered. For relative density rho=1/2 there are solutions, if holes in the body are…

Mechanical properties of the radio frequency field emitted by an antenna array
Angular momentum densities of electromagnetic beams are connected to helicity (circular polarization) and topological charge (azimuthal phase shift and vorticity). Computing the electromagnetic…

Wetting problem for multi-component fluid mixtures
In this paper we propose an extension of the Cahn method to binary mixtures and study the problem of wetting near a two-phase critical point without any assumption on the form of intermolecular…

Bare and dressed particles in collision theory
The bare-dressed technique is, for the first time, used in collision theory. The approach is valid for classical as well for quantum binary elastic collisions in the non relativistic regime. The same…

Conjectured Metastable Super-Explosives formed under High Pressure for Thermonuclear Ignition
If matter is suddenly put under a high pressure, for example a pressure of 100 Mb =1014 dyn/cm2, it can undergo a transformation into molecular excited states, bound by inner electron shells, with…

Radiative Damping and Functional Differential Equations
We propose a general technique to solve the classical many-body problem with radiative damping. We modify the short-distance structure of Maxwell electrodynamics. This allows us to avoid runaway…

Vibrations of liquid drops in film boiling phenomena: the mathematical model
Flattened liquid drops poured on a very hot surface evaporate quite slowly and float on a film of their own vapour. In the cavities of a surface, an unusual type of vibrational motions occurs. Large…

Extreme Lagrangian acceleration in confined turbulent flow
A Lagrangian study of two-dimensional turbulence for two different geometries, a periodic and a confined circular geometry, is presented to investigate the influence of solid boundaries on the…

Nonlinear model of source of a elastic field
A general description of the long-range elastic interaction is proposed. The far-field type of the interaction is determined by the way of symmetry breaking of the distribution of the elastic field…

Modelling of the moving deformed triple contact line: influence of the fluid inertia
For partial wetting, motion of the triple liquid-gas-solid contact line is influenced by heterogeneities of the solid surface. This influence can be strong in the case of inertial (e.g. oscillation)…

Multiple solutions of steady MHD flow of dilatant fluids
In this paper we consider the problem of a steady MHD flow of a non-Newtonian power-law and electrically conducting fluid in presence of an applied magnetic field. The boundary layer equations are…
