THE COMPUTER-AIDED CONTROLLING OF TECHNICAL AND TECHNOLOGICAL PLANTS IN THE WAVELET MEDIUM [PDF]

Техника и технология пищевых производств, 2015
Methods of formalizing material flows created in certain knots of structure-and-functional diagram of the mixture producing aggregate are considered, that are founded on transforming one-dimensional initial flow signals into multi-dimensional ones.

Wigner distribution function of volume holograms [PDF]

Optics Letters, 2009
Based on a linear systems approach, we derive the Wigner distribution function (WDF) of a 4f imager with a volume holographic three-dimensional pupil; then we obtain the WDF of the volume hologram itself by using the shearing properties of the WDF. Two common configurations, plane and spherical wave reference volume holograms, are examined in detail ...

Comparison of DeePMD, MTP, GAP, ACE and MACE Machine‐Learned Potentials for Radiation‐Damage Simulations: A User Perspective

Advanced Intelligent Discovery, EarlyView.
The authors evaluated six machine‐learned interatomic potentials for simulating threshold displacement energies and tritium diffusion in LiAlO2 essential for tritium production. Trained on the same density functional theory data and benchmarked against traditional models for accuracy, stability, displacement energies, and cost, Moment Tensor Potential ...

Exploring phase space properties of nonlinear Kerr-cavity interacting with a qubit: Spontaneous-emission damping effect

Alexandria Engineering Journal
In our work, we have explored the phase space nonlinear coherent-Kerr-cavity nonclassicality and purity loss induced by off-resonant intensity-dependent cavity-qubit interactions under atomic spontaneous-emission dissipation effect. The generation of the

Comment on ‘Wigner function for a particle in an infinite lattice’

New Journal of Physics, 2013
It is pointed out that in a recent paper (2012 New J. Phys. 14 103009) in which a Wigner function for a particle in an infinite lattice (a system described by an unbounded discrete coordinate and its conjugate angle-like momentum) has been introduced, no

Spin kinetic theory - quantum kinetic theory in extended phase space

, 2010
The concept of phase space distribution functions and their evolution is used in the case of en enlarged phase space. In particular, we include the intrinsic spin of particles and present a quantum kinetic evolution equation for a scalar quasi ...

Quantum nature of Wigner function for inflationary tensor perturbations

Journal of High Energy Physics, 2020
We study the Wigner function for the inflationary tensor perturbation defined in the real phase space. We compute explicitly the Wigner function including the contributions from the cubic self-interaction Hamiltonian of tensor perturbations.

Design Principles for Next Generation of Small Organic Molecules for Photodynamics Therapy Revealed by Nonadiabatic Molecular Dynamics

Chemistry – A European Journal, EarlyView.
Molecular design reshapes the landscape of excited‐state relaxation. Nonadiabatic dynamics reveal how electronic structure guides population flow between competing pathways beyond static energetic arguments. ABSTRACT Nitrobenzochalcogenadiazole derivatives are emerging candidates for photodynamic therapy (PDT), yet the precise mechanisms governing ...

Realisability of Wigner distributions

Electronics Letters, 1989
A time-frequency distribution C(t, omega ) is said to be WD-realisable if it is shown to be the Wigner distribution (WD) of a signal f(t). Conditions for this realisability are obtained using the FON basis vector representation of signals in L/sup 2/. >

Structural Properties of Yukawa One‐Component Plasmas Revisited

Contributions to Plasma Physics, EarlyView.
ABSTRACTYukawa one‐component plasmas are fully described in terms of the Coulomb coupling parameter Γ$$ \Gamma $$ and the screening parameter κ$$ \kappa $$. One of their remarkable properties is the existence of lines of constant effective coupling, Γeff(Γ,κ)$$ {\Gamma}_{\mathrm{eff}}\left(\Gamma, \kappa \right) $$, along which their short‐range ...
