Modelling of a Wireless Channel with Time Dependent Parameters

open access: yesScientific Journal of Gdynia Maritime University, 2019
It is convenient to analyse wireless channels and links by exploiting their input-output description. This approach relies on treating the system as a black box, whose behaviour can be fully described by the relationship between the input and output ...

Non-classical paths in interference experiments

open access: yes, 2014
In a double slit interference experiment, the wave function at the screen with both slits open is not exactly equal to the sum of the wave functions with the slits individually open one at a time.

Three superposition principles: currents, continuity equations and curves of measures

open access: yes, 2015
We establish a general superposition principle for curves of measures solving a continuity equation on metric spaces without any smooth structure nor underlying measure, representing them as marginals of measures concentrated on the solutions of the ...

STRAINS SUPERPOSITION PRINCIPLE WHEN CONSTRUCTION ELEMENTS HAVE STRUCTURAL DAMAGES

open access: yesStructural Mechanics of Engineering Constructions and Buildings, 2011
Rheological state equations of materials are obtained on the base of the principle of the superposition of fraction creep strains. Boltzmann the first applied this principle when the fraction strains were independent of the value and duration of the rest

Brownian dynamics investigation of the Boltzmann superposition principle for orthogonal superposition rheology [PDF]

open access: yesThe Journal of Chemical Physics, 2019
The most general linear equation describing the stress response at time t to a time-dependent shearing perturbation may be written as the integral over the past history t′ of a time dependent relaxation modulus, depending on t − t′, multiplied by the perturbing shear rate at time t′.

Gravitational vacuum polarization phenomena due to the Higgs field

open access: yes, 2012
In the standard model the mass of elementary particles is considered as a dynamical property emerging from their interaction with the Higgs field. We show that this assumption implies peculiar deviations from the law of universal gravitation in its ...

Quantum thermalization and equilibrium state with multiple temperatures

open access: yes, 2013
A large class of isolated quantum system in a pure state can equilibrate and serve as a heat bath. We show that once the equilibrium is reached, any of its subsystems that is much smaller than the isolated system is thermalized such that the subsystem is

Superposition Principle for Differential Inclusions

open access: yes, 2018
We prove an extension of the Superposition Principle by Ambrosio-Gigli-Savare in the context of a control problem. In particular, we link the solutions of a finite-dimensional control system, with dynamics given by a differential inclusion, to a solution of a continuity equation in the space of probability measures with admissible vector field.

Quantum test of the equivalence principle for atoms in superpositions of internal energy eigenstates

open access: yes, 2017
The Einstein Equivalence Principle (EEP) has a central role in the understanding of gravity and space-time. In its weak form, or Weak Equivalence Principle (WEP), it directly implies equivalence between inertial and gravitational mass.
