The quantum energy of the photon radiated by a body with de Broglie wavelength, as it moves with velocity v, can be defined within relativistic physics by rest energy E₀. In this way, we can show the connection between the quantum of radiation energy of the body and the rest of energy E₀ and thus combine what has been incompatible so far, namely relativistic and quantum physics. So, here we discuss the unification of relativistic and quantum physics by introducing the factor k that is analog to the Lorentz factor in Einstein's theory of relativity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=de%20Brogli%20wavelength" title="de Brogli wavelength">de Brogli wavelength</a>, <a href="https://publications.waset.org/abstracts/search?q=relativistic%20physics" title=" relativistic physics"> relativistic physics</a>, <a href="https://publications.waset.org/abstracts/search?q=rest%20energy" title=" rest energy"> rest energy</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20physics" title=" quantum physics"> quantum physics</a> </p> <a href="https://publications.waset.org/abstracts/135170/de-broglie-wavelength-defined-by-the-rest-energy-e0-and-its-velocity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135170.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">156</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12406</span> Multisymplectic Geometry and Noether Symmetries for the Field Theories and the Relativistic Mechanics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Loumi-Fergane">H.

In this paper, we expand the vector fields associated to infinitesimal symmetries which give rise to invariant quantities as Noether currents for classical field theories and relativistic mechanic using the multisymplectic geometry where the Poincaré-Cartan form has thus been greatly simplified using the Second Order Partial Differential Equation (SOPDE) for multi-vector fields verifying Euler equations. These symmetries have been classified naturally according to the construction of the fiber bundle used.  In this work, unlike other works using the analytical method, our geometric model has allowed us firstly to distinguish the angular moments of the gauge field obtained during different transformations while these moments are gathered in a single expression and are obtained during a rotation in the Minkowsky space. Secondly, no conditions are imposed on the Lagrangian of the mechanics with respect to its dependence in time and in q<sup>i</sup>, the currents obtained naturally from the transformations are respectively the energy and the momentum of the system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conservation%20laws" title="conservation laws">conservation laws</a>, <a href="https://publications.waset.org/abstracts/search?q=field%20theories" title=" field theories"> field theories</a>, <a href="https://publications.waset.org/abstracts/search?q=multisymplectic%20geometry" title=" multisymplectic geometry"> multisymplectic geometry</a>, <a href="https://publications.waset.org/abstracts/search?q=relativistic%20mechanics" title=" relativistic mechanics"> relativistic mechanics</a> </p> <a href="https://publications.waset.org/abstracts/74108/multisymplectic-geometry-and-noether-symmetries-for-the-field-theories-and-the-relativistic-mechanics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74108.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">206</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12405</span> Feedback Matrix Approach for Relativistic Runaway Electron Avalanches Dynamics in Complex Electric Field Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Egor%20Stadnichuk">Egor Stadnichuk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Relativistic runaway electron avalanches (RREA) are a widely accepted source of thunderstorm gamma-radiation. In regions with huge electric field strength, RREA can multiply via relativistic feedback. The relativistic feedback is caused both by positron production and by runaway electron bremsstrahlung gamma-rays reversal. In complex multilayer thunderstorm electric field structures, an additional reactor feedback mechanism appears due to gamma-ray exchange between separate strong electric field regions with different electric field directions. The study of this reactor mechanism in conjunction with the relativistic feedback with Monte Carlo simulations or by direct solution of the kinetic Boltzmann equation requires a significant amount of computational time. In this work, a theoretical approach to study feedback mechanisms in RREA physics is developed. It is based on the matrix of feedback operators construction. With the feedback matrix, the problem of the dynamics of avalanches in complex electric structures is reduced to the problem of finding eigenvectors and eigenvalues. A method of matrix elements calculation is proposed. The proposed concept was used to study the dynamics of RREAs in multilayer thunderclouds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=terrestrial%20Gamma-ray%20flashes" title="terrestrial Gamma-ray flashes">terrestrial Gamma-ray flashes</a>, <a href="https://publications.waset.org/abstracts/search?q=thunderstorm%20ground%20enhancement" title=" thunderstorm ground enhancement"> thunderstorm ground enhancement</a>, <a href="https://publications.waset.org/abstracts/search?q=relativistic%20runaway%20electron%20avalanches" title=" relativistic runaway electron avalanches"> relativistic runaway electron avalanches</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma-rays" title=" gamma-rays"> gamma-rays</a>, <a href="https://publications.waset.org/abstracts/search?q=high-energy%20atmospheric%20physics" title=" high-energy atmospheric physics"> high-energy atmospheric physics</a>, <a href="https://publications.waset.org/abstracts/search?q=TGF" title=" TGF"> TGF</a>, <a href="https://publications.waset.org/abstracts/search?q=TGE" title=" TGE"> TGE</a>, <a href="https://publications.waset.org/abstracts/search?q=thunderstorm" title=" thunderstorm"> thunderstorm</a>, <a href="https://publications.waset.org/abstracts/search?q=relativistic%20feedback" title=" relativistic feedback"> relativistic feedback</a>, <a href="https://publications.waset.org/abstracts/search?q=reactor%20feedback" title=" reactor feedback"> reactor feedback</a>, <a href="https://publications.waset.org/abstracts/search?q=reactor%20model" title=" reactor model"> reactor model</a> </p> <a href="https://publications.waset.org/abstracts/142458/feedback-matrix-approach-for-relativistic-runaway-electron-avalanches-dynamics-in-complex-electric-field-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142458.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">172</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12404</span> Modeling a Feedback Concept in a Spherical Thundercloud Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zemlianskaya%20Daria">Zemlianskaya Daria</a>, <a href="https://publications.waset.org/abstracts/search?q=Egor%20Stadnichuk"> Egor Stadnichuk</a>, <a href="https://publications.waset.org/abstracts/search?q=Ekaterina%20Svechnikova"> Ekaterina Svechnikova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Relativistic runaway electron avalanches (RREAs) are generally accepted as a source of thunderstorms gamma-ray radiation.

The stability of the orbits is analyzed using the particle orbit theory. In order to get a better understanding of the interaction wave-particle, we decompose the azimuthally electric field component as the superposition of right and left-hand circular polarization standing waves. The trajectory, energy and phase-shift of the electron are found through a numerical solution of the relativistic Newton-Lorentz equation in a finite difference method by the Boris method. It is shown that an electron longitudinally injected with an energy of 7 keV in a radial position r=Rc/2, being Rc the cavity radius, is accelerated up to energy of 90 keV by an electric field strength of 14 kV/cm and frequency of 2.45 GHz. This energy can be used to produce X-ray for medical imaging. These results can be used as a starting point for study the acceleration of electrons in a magnetic field changing slowly in time (GYRAC), which has some important applications as the electron cyclotron resonance ion proton accelerator (ECR-IPAC) for cancer therapy and to control plasma bunches with relativistic electrons. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Boris%20method" title="Boris method">Boris method</a>, <a href="https://publications.waset.org/abstracts/search?q=electron%20cyclotron%20resonance" title=" electron cyclotron resonance"> electron cyclotron resonance</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20difference%20method" title=" finite difference method"> finite difference method</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20orbit%20theory" title=" particle orbit theory"> particle orbit theory</a>, <a href="https://publications.waset.org/abstracts/search?q=X-ray" title=" X-ray"> X-ray</a> </p> <a href="https://publications.waset.org/abstracts/98818/study-of-electron-cyclotron-resonance-acceleration-by-cylindrical-te011-mode" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98818.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">159</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12402</span> Relativistic Energy Analysis for Some q Deformed Shape Invariant Potentials in D Dimensions Using SUSYQM Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Suparmi">A.

The amount of the precession of the perihelion for Einstein’s theory of gravitation has been explained by means of the inverse fourth power force(inverse third power potential) introduced totheory of gravitation through Schwarzschild metric However, the methodology has a serious shortcoming that it is impossible to explain the cause for the precession of the perihelion in the planetary orbits. According to our study, without taking the cause for the precession of the perihelion, 6 methods can explain the amount of the precession of the perihelion discovered by Leverrier. Therefore, the problem of what caused the perihelion to precess in the planetary orbits must be solved for physics because it is a profound scientific and technological problem for a basic experiment in construction of relativistic theory of gravitation. The scientific solution to the problem proved that Einstein’s explanation for the planetary orbits is a magic made by the numerical expressions obtained from fictitious gravitation introduced to theory of gravitation and wrong definition of proper time The problem of the precession of the perihelion seems solved already by means of general theory of relativity, but, in essence, the cause for the astronomical phenomenon has not been successfully explained for astronomy yet. The right solution to the problem comes from generalized theory of gravitation. Therefore, in this paper, it has been shown that by means of Schwarzschild field and the physical quantities of relativistic Lagrangian redflected in it, fictitious gravitation is not the main factor which can cause the perihelion to precess in the planetary orbits. In addition to it, it has been shown that the main factor which can cause the perihelion to precess in the planetary orbits is the inverse third power force existing really in the relativistic region in the Solar system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inverse%20third%20power%20force" title="inverse third power force">inverse third power force</a>, <a href="https://publications.waset.org/abstracts/search?q=precession%20of%20the%20perihelion" title=" precession of the perihelion"> precession of the perihelion</a>, <a href="https://publications.waset.org/abstracts/search?q=fictitious%20gravitation" title=" fictitious gravitation"> fictitious gravitation</a>, <a href="https://publications.waset.org/abstracts/search?q=planetary%20orbits" title=" planetary orbits"> planetary orbits</a> </p> <a href="https://publications.waset.org/abstracts/192598/causes-for-the-precession-of-the-perihelion-in-the-planetary-orbits" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192598.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">11</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12400</span> Ground State Properties of Neutron Magic Isotones</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20Saxena">G.

In addition, the possible locations of the proton and neutron drip-lines as well as the (Z,N) values for the shell closures as suggested by the detailed analyzes of the single particle spectra, and the two proton and two-neutron separation energies for the different isotonic chains are also discussed in detail. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=relativistic%20mean%20field%20theory" title="relativistic mean field theory">relativistic mean field theory</a>, <a href="https://publications.waset.org/abstracts/search?q=neutron%20magic%20nuclei" title=" neutron magic nuclei"> neutron magic nuclei</a>, <a href="https://publications.waset.org/abstracts/search?q=shell%20closure" title=" shell closure"> shell closure</a>, <a href="https://publications.waset.org/abstracts/search?q=separation%20energy" title=" separation energy"> separation energy</a>, <a href="https://publications.waset.org/abstracts/search?q=deformation" title=" deformation"> deformation</a> </p> <a href="https://publications.waset.org/abstracts/13497/ground-state-properties-of-neutron-magic-isotones" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13497.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">404</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12399</span> Contribution of Exchange-correlation Effects on Weakly Relativistic Plasma Expansion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Fermous">Rachid Fermous</a>, <a href="https://publications.waset.org/abstracts/search?q=Rima%20Mebrek"> Rima Mebrek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Plasma expansion is an important physical process that takes place in laser interactions with solid targets. Within a self-similar model for the hydrodynamic multi-fluid equations, we investigated the expansion of dense plasma. The weakly relativistic electrons are produced by ultra-intense laser pulses, while ions are supposed to be in a non-relativistic regime. It is shown that dense plasma expansion is found to be governed mainly by quantum contributions in the fluid equations that originate from the degenerate pressure in addition to the nonlinear contributions from exchange and correlation potentials. The quantum degeneracy parameter proﬁle provides clues to set the limit between under-dense and dense relativistic plasma expansions at a given density and temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plasma%20expansion" title="plasma expansion">plasma expansion</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20degeneracy" title=" quantum degeneracy"> quantum degeneracy</a>, <a href="https://publications.waset.org/abstracts/search?q=weakly%20relativistic" title=" weakly relativistic"> weakly relativistic</a>, <a href="https://publications.waset.org/abstracts/search?q=under-dense%20%20plasma" title=" under-dense plasma"> under-dense plasma</a> </p> <a href="https://publications.waset.org/abstracts/167933/contribution-of-exchange-correlation-effects-on-weakly-relativistic-plasma-expansion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167933.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">87</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12398</span> Spherical Nonlinear Wave Propagation in Relativistic Quantum Plasma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Abdikian">Alireza Abdikian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> By assuming a quantum relativistic degenerate electron-positron (e-p) plasma media, the nonlinear acoustic solitary propagation in the presence of the stationary ions for neutralizing the plasma background of bounded cylindrical geometry was investigated.

Based on these terms, two relativistic effects of rotation are discovered: (i) the tangential velocity in the region of Outside Critical Cylinder (OCC) is not superluminal due to the existence of space-time exchange; (ii) some of the physical quantities of the rotational body have an opposite mathematic sign at OCC versus those at Inside Critical Cylinder (ICC), which is termed as the Critical Cylindrical Effect (CCE). The laboratory experiments demonstrate that the repulsive force exerted on an anion by electrons will change to an attractive force by the electrons in precession while the anion is at OCC of the precession.

We can observe interesting fact that for such systems a class of potentials, namely the PT symmetric and η-pseudo Hermitian admit real eigenvalues despite being non Hermitian and analogues of those system have been experimentally verified. Point to be noted that relativistic non Hermitian (PT symmetric) interactions can be realized in optical structures and also there exists photonic realization of the (1 + 1) dimensional Dirac oscillator. We have thoroughly studied generalized Dirac oscillators with non Hermitian interactions in (1 + 1) dimensions. To be more specific, we have examined η pseudo Hermitian interactions within the framework of generalized Dirac oscillator in (1 + 1) dimensions. In particular, we have obtained a class of interactions which are η-pseudo Hermitian and the metric operator η could have been also found explicitly. It is possible to have exact solutions of the generalized Dirac oscillator for some choices of the interactions. Subsequently we have employed the mapping between the generalized Dirac oscillator and the Jaynes Cummings (JC) model by spin flip to obtain a class of exactly solvable non Hermitian JC as well as anti Jaynes Cummings (AJC) type models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dirac%20oscillator" title="Dirac oscillator">Dirac oscillator</a>, <a href="https://publications.waset.org/abstracts/search?q=non-Hermitian%20quantum%20system" title=" non-Hermitian quantum system"> non-Hermitian quantum system</a>, <a href="https://publications.waset.org/abstracts/search?q=Hermitian" title=" Hermitian"> Hermitian</a>, <a href="https://publications.waset.org/abstracts/search?q=relativistic" title=" relativistic "> relativistic </a> </p> <a href="https://publications.waset.org/abstracts/4071/generalized-dirac-oscillators-associated-to-non-hermitian-quantum-mechanical-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4071.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">459</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12394</span> Disintegration of Deuterons by Photons Reaction Model for GEANT4 with Dibaryon Formalism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jae%20Won%20Shin">Jae Won Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Chang%20Ho%20Hyun"> Chang Ho Hyun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A disintegration of deuterons by photons (dγ → np) reaction model for GEANT4 is developed in this work. An effective field theory with dibaryon fields Introducing a dibaryon field, we can take into account the effective range contribution to the propagator up to infinite order, and it consequently makes the convergence of the theory better than the pionless effective field theory without dibaryon fields. We develop a hadronic model for GEANT4 which is specialized for the disintegration of the deuteron by photons, dγ → np. For the description of two-nucleon interactions, we employ an effective field theory so called pionless theory with dibaryon fields (dEFT). In spite of its simplicity, the theory has proven very effective and useful in the applications to various two-nucleon systems and processes at low energies. We apply the new model of GEANT4 (G4dEFT) to the calculation of total and differential cross sections in dγ → np, and obtain good agreements to experimental data for a wide range of incoming photon energies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=d%CE%B3%20%E2%86%92%20np" title="dγ → np">dγ → np</a>, <a href="https://publications.waset.org/abstracts/search?q=dibaryon%20fields" title=" dibaryon fields"> dibaryon fields</a>, <a href="https://publications.waset.org/abstracts/search?q=effective%20field%20theory" title=" effective field theory"> effective field theory</a>, <a href="https://publications.waset.org/abstracts/search?q=GEANT4" title=" GEANT4"> GEANT4</a> </p> <a href="https://publications.waset.org/abstracts/61584/disintegration-of-deuterons-by-photons-reaction-model-for-geant4-with-dibaryon-formalism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61584.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">378</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12393</span> Gravitationally Confined Relativistic Neutrinos and Mathematical Modeling of the Structure of Pions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Constantinos%20Vayenas">Constantinos Vayenas</a>, <a href="https://publications.waset.org/abstracts/search?q=Athanasios%20Fokas"> Athanasios Fokas</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimitrios%20Grigoriou"> Dimitrios Grigoriou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We use special relativity to compute the inertial and thus gravitational mass of relativistic electron and muon neutrinos, and we find that, for neutrino kinetic energies above 150 MeV/c2, these masses are in the Planck mass range.

When the laser pulse is p-polarized, plasma effects do modify the harmonic spectrum, weakening the so-called universal decay with p=8/3 to p=5/3, or below. In this work, appeal is made to a single particle radiation model in support of the predictions from particle-in-cell (PIC) simulations. Using this numerical technique we further show that the emission radiated by electrons -that are relativistically accelerated by the laser field inside the plasma, after being expelled into vacuum, the so-called Brunel electrons is characterized not only by the plasma line but also by ultraviolet harmonic orders described by the 5/3 decay index. Results obtained from these simulations suggest that for ultra-relativistic light intensities, the spectral decay index is further reduced, with p now in the range 2/3 ≤ p ≤ 4/3. This reduction is indicative of a transition from the regime where Brunel-induced plasma radiation influences the spectrum to one dominated by bremsstrahlung emission from the Brunel electrons. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ultra-relativistic" title="ultra-relativistic">ultra-relativistic</a>, <a href="https://publications.waset.org/abstracts/search?q=laser-plasma%20interactions" title=" laser-plasma interactions"> laser-plasma interactions</a>, <a href="https://publications.waset.org/abstracts/search?q=high-order%20harmonic%20emission" title=" high-order harmonic emission"> high-order harmonic emission</a>, <a href="https://publications.waset.org/abstracts/search?q=radiation" title=" radiation"> radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=spectrum" title=" spectrum "> spectrum </a> </p> <a href="https://publications.waset.org/abstracts/27628/radiation-emission-from-ultra-relativistic-plasma-electrons-in-short-pulse-laser-light-interactions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27628.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">464</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12391</span> Stimulated Raman Scattering of Ultra Intense Hollow Gaussian Beam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prerana%20Sharma">Prerana Sharma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Effect of relativistic nonlinearity on stimulated Raman scattering of the propagating laser beam carrying null intensity in center (hollow Gaussian beam) by excited plasma wave are studied in a collisionless plasma.

However, there is a need to develop its theoretical bases in connection to practice. The present paper is a starting attempt in this regard to provide a space from which to think about neuroeducational theory and invoke more investigation in this area. Accordingly, a comprehensive theory of neuroeducation could be defined as grouping or clustering of concepts and propositions that describe and explain the nature of human learning to provide valid interpretations and implications useful for educational practice in relation to philosophical aspects or values. Whereas it should be originated from the philosophical foundations of the field and explain its normative significance, it needs to be testable in terms of rigorous evidence to fundamentally advance contemporary educational policy and practice. There is thus pragmatically a need to include a course on neuroeducational theory into the curriculum of the field.

Initially we carried out a study on numerical methods of unidimensional Finite Volume, namely Lax-Friedrichs, Lax-Wendroff, Nessyahu-Tadmor method and Godunov methods dependent on Riemann problems, applied to equations Euler in order to verify their main features and make comparisons among those methods. It was then implemented the method of Finite Volume Centered of Nessyahu-Tadmor, a numerical schemes that has a formulation free and without dimensional separation of Riemann problem solvers, even in two or more spatial dimensions, at this point, already applied in equations GRMHD. Finally, the Nessyahu-Tadmor method was possible to obtain stable numerical solutions - without spurious oscillations or excessive dissipation - from the magnetized accretion disk process in rotation with respect to a central black hole (BH) Schwarzschild and immersed in a magnetosphere, for the ejection of matter in the form of jet over a distance of fourteen times the radius of the BH, a record in terms of astrophysical simulation of this kind. Also in our simulations, we managed to get substructures jets. A great advantage obtained was that, with the our code, we got simulate GRMHD equations in a simple personal computer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20volume%20methods" title="finite volume methods">finite volume methods</a>, <a href="https://publications.waset.org/abstracts/search?q=central%20schemes" title=" central schemes"> central schemes</a>, <a href="https://publications.waset.org/abstracts/search?q=fortran%2090" title=" fortran 90"> fortran 90</a>, <a href="https://publications.waset.org/abstracts/search?q=relativistic%20astrophysics" title=" relativistic astrophysics"> relativistic astrophysics</a>, <a href="https://publications.waset.org/abstracts/search?q=jet" title=" jet"> jet</a> </p> <a href="https://publications.waset.org/abstracts/19952/central-finite-volume-methods-applied-in-relativistic-magnetohydrodynamics-applications-in-disks-and-jets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19952.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">454</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12388</span> Value from Environmental and Cultural Perspectives or Two Sides of the Same Coin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vilem%20Paril">Vilem Paril</a>, <a href="https://publications.waset.org/abstracts/search?q=Dominika%20Tothova"> Dominika Tothova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper discusses the value theory in cultural heritage and the value theory in environmental economics. Two economic views of the value theory are compared within the field of cultural heritage maintenance and within the field of the environment. The main aims are to find common features in these two differently structured theories under the layer of differently defined terms as well as really differing features of these two approaches, to clear the confusion which stems from different terminology as in fact these terms capture the same aspects of reality and to show possible inspiration these two perspectives can offer one another. Another aim is to present these two value systems in one value framework. First, important moments of the value theory from the economic perspective are presented, leading to the marginal revolution of (not only) the Austrian School. Then the theory of value within cultural heritage and environmental economics are explored. Finally, individual approaches are compared and their potential mutual inspiration searched for. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cultural%20heritage" title="cultural heritage">cultural heritage</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20economics" title=" environmental economics"> environmental economics</a>, <a href="https://publications.waset.org/abstracts/search?q=existence%20value" title=" existence value"> existence value</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20theory" title=" value theory"> value theory</a> </p> <a href="https://publications.waset.org/abstracts/27902/value-from-environmental-and-cultural-perspectives-or-two-sides-of-the-same-coin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27902.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">321</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12387</span> A Unification and Relativistic Correction for Boltzmann’s Law</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lloyd%20G.%20Allred">Lloyd G.

Boltzmann’s law and the Maxwell-Boltzmann distribution describe the distribution of velocity of a particle in plasma as a function of mass and temperature. Particles with the same mass tend to have the same velocity. By expressing the same law in terms of energy alone, the author obtains a distribution independent of mass. In summary, for particles in plasma, the energies tend to equalize, independent of the masses of the individual particles. For high-energy plasma, the original law predicts velocities greater than the speed of light. If one uses Einstein’s formula for energy (<em>E=mc<sup>2</sup></em>), then a relativistic correction is not required. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cosmology" title="cosmology">cosmology</a>, <a href="https://publications.waset.org/abstracts/search?q=EMP" title=" EMP"> EMP</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20physics" title=" plasma physics"> plasma physics</a>, <a href="https://publications.waset.org/abstracts/search?q=relativity" title=" relativity"> relativity</a> </p> <a href="https://publications.waset.org/abstracts/84272/a-unification-and-relativistic-correction-for-boltzmanns-law" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84272.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">219</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12386</span> Generalized Mean-Field Theory of Phase Unwrapping via Multiple Interferograms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yohei%20Saika">Yohei Saika</a> </p> <p class="card-text"><strong>Abstract:</strong></p> On the basis of Bayesian inference using the maximizer of the posterior marginal estimate, we carry out phase unwrapping using multiple interferograms via generalized mean-field theory.

All of the fields tackled by Kelsen are regarded as part of his “pure theory of law.” While the link between international law and Kelsen’s pure theory of law is apparent, the same cannot be said about the link between the theory of democracy and his pure theory of law. On the contrary, the general thinking concerning Kelsen’s thought is that it can be used to legitimize authoritarian regimes. The aim of this presentation is to address this concern by identifying the common ground between Kelsen’s pure theory of law and his theory of democracy and to show that they are compatible in a way that his pure theory of law and authoritarianism cannot be. The conceptual analysis of the purity of Kelsen’s theory and his goal of creating ideology-free legal science hints at how Kelsen’s pure theory of law and the theory of democracy are brought together. The presentation will first demonstrate that these two conceptions have common underlying values and meta-ethical convictions. Both are founded on relativism and a rational worldview, and the aim of both is peaceful co-existence. Second, it will be demonstrated that the separation of law and morality provides the maximum space for deliberation within democratic processes. The conclusion of this analysis is that striking similarities exist between Kelsen’s legal theory and his theory of democracy. These similarities are grounded in the Enlightenment tradition and its values, including rationality, a scientific worldview, tolerance, and equality. This observation supports the claim that, for Kelsen, legal positivism and the theory of democracy are not two separate theories but rather stem from the same set of values and from Kelsen’s relativistic worldview. Furthermore, three main issues determine Kelsen’s orientation toward a positivistic and democratic outlook. The first, which is associated with personality type, is the distinction between absolutism and relativism. The second, which is associated with the values that Kelsen favors in the social order, is peace. The third is legality, which creates the necessary condition for democracy to thrive and reveals that democracy is capable of fulfilling Kelsen’s ideal of law at its fullest. The first two categories exist in the background of Kelsen’s pure theory of law, while the latter is an inherent part of Kelsen’s concept of law. The analysis of the text concerning natural law doctrine and democracy indicates that behind the technical language of Kelsen’s pure theory of law is a strong concern with the trends that appeared after World War I. Despite his rigorous scientific mind, Kelsen was deeply humanistic. He tried to create a powerful intellectual weapon to provide strong arguments for peaceful coexistence and a rational outlook in Europe. The analysis provided by this presentation facilitates a broad theoretical, philosophical, and political understanding of Kelsen’s perspectives and, consequently, urges a strong endorsement of Kelsen’s approach to constitutional democracy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hans%20kelsen" title="hans kelsen">hans kelsen</a>, <a href="https://publications.waset.org/abstracts/search?q=democracy" title=" democracy"> democracy</a>, <a href="https://publications.waset.org/abstracts/search?q=legal%20positivism" title=" legal positivism"> legal positivism</a>, <a href="https://publications.waset.org/abstracts/search?q=pure%20theory%20of%20law" title=" pure theory of law"> pure theory of law</a> </p> <a href="https://publications.waset.org/abstracts/152723/the-relations-between-hans-kelsens-concept-of-law-and-the-theory-of-democracy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152723.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">109</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12384</span> The Grand Unified Theory of Everything as a Generalization to the Standard Model Called as the General Standard Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Deljoo">Amir Deljoo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The endeavor to comprehend the existence have been the center of thought for human in form of different disciplines and now basically in physics as the theory of everything.

Our dynamical model includes Newtonian perturbations of eight planets, the Moon, the Sun and three massive asteroid (1Ceres, 2Palas and 4Vesta).

The electronic structure is performed within the framework of the Spin-Polarized Relativistic (SPR) Linear Muffin-Tin Orbitals (LMTO) with the Atomic Sphere Approximation (ASA) method. During the variational principle, the crystal wave function is expressed as a linear combination of the Bloch sums of the so-called relativistic muffin-tin orbitals centered on the atomic sites. The crystalline structure is calculated after an atomic relaxation process using the optimization of the total energy with respect to the atomic interplane distance. A body-centered tetragonal (BCT) pseudomorphic crystalline structure with a tetragonality ratio c/a larger than unity is found. The magnetic behaviour is characterized by an enhanced magnetic moment and a ferromagnetic interplane coupling. The polar magneto-optical Kerr effect spectra are given over a photon energy range extended to 15eV and the microscopic origin of the most interesting features are interpreted by interband transitions. Unlike thin layers, the anisotropy in the ultra-thin films is characterized by a perpendicular magnetization which is perpendicular to the film plane. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ultrathin%20films" title="ultrathin films">ultrathin films</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetism" title=" magnetism"> magnetism</a>, <a href="https://publications.waset.org/abstracts/search?q=magneto-optics" title=" magneto-optics"> magneto-optics</a>, <a href="https://publications.waset.org/abstracts/search?q=pseudomorphic%20structure" title=" pseudomorphic structure"> pseudomorphic structure</a> </p> <a href="https://publications.waset.org/abstracts/25728/theoretical-study-of-structural-magnetic-and-magneto-optical-properties-of-ultrathin-films-of-fecu-001" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25728.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">335</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12380</span> PhD Research Design and Descriptive Theory: Theoretical Framework for Development of Integrated Management System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Quashie">Samuel Quashie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The importance of theory for PhD construction management research cannot be underestimated, as it requires a sound theoretical basis.

The fluid is considered to be magnetized and subjected to the influence of a magnetic field that is generated during the early stages of relativistic heavy ion collisions. We assume boost invariance along the beam line, which is represented by the z coordinate, and fluid expansion in the x direction. Additionally, we assume that the magnetic field is perpendicular to the reaction plane, which corresponds to the y direction. The fluid is considered to have infinite electrical conductivity. To analyze this system, we solve the coupled Maxwell and conservation equations. By doing so, we are able to determine the time and space dependence of the energy density, velocity, and magnetic field in the transverse plane of the viscous magnetized hot plasma.

Einstein's path, which is mainly based on particle mechanics, and the path of Paul Dirac and others, which is based on wave mechanics, the incompatibility of the two approaches is due to the radical difference in the initial assumptions and the mathematical nature of each approach. Logical thinking in modern physics leads us to two problems: - In quantum mechanics, despite its success, the problem of measurement and the problem of wave function interpretation is still obscure. - In special relativity, despite the success of the equivalence of rest-mass and energy, but at the speed of light, the fact that the energy becomes infinite is contrary to logic because the speed of light is not infinite, and the mass of the particle is not infinite too. These contradictions arise from the overlap of relativistic and quantum mechanics in the neighborhood of the speed of light, and in order to solve these problems, one must understand well how to move from relativistic mechanics to quantum mechanics, or rather, to unify them in a way different from Dirac's method, in order to go along with God or Nature, since, as Einstein said, "God doesn't play dice." From De Broglie's hypothesis about wave-particle duality, Léon Brillouin's definition of the new proper time was deduced, and thus the quantum Lorentz factor was obtained. Finally, using the Euler-Lagrange equation, we come up with new equations in quantum mechanics. In this paper, the two problems in modern physics mentioned above are solved; it can be said that this new approach to quantum mechanics will enable us to unify it with general relativity quite simply. If the experiments prove the validity of the results of this research, we will be able in the future to transport the matter at speed close to the speed of light. Finally, this research yielded three important results: 1- Lorentz quantum factor. 2- Planck energy is a limited case of Einstein energy. 3- Real quantum mechanics, in which new equations for quantum mechanics match and exceed Dirac's equations, these equations have been reached in a completely different way from Dirac's method. These equations show that quantum mechanics is a limited case of relativistic mechanics. At the Solvay Conference in 1927, the debate about quantum mechanics between Bohr, Einstein, and others reached its climax, while Bohr suggested that if particles are not observed, they are in a probabilistic state, then Einstein said his famous claim ("God does not play dice"). Thus, Einstein was right, especially when he didn't accept the principle of indeterminacy in quantum theory, although experiments support quantum mechanics. However, the results of our research indicate that God really does not play dice; when the electron disappears, it turns into amicable particles or an elastic medium, according to the above obvious equations. Likewise, Bohr was right also, when he indicated that there must be a science like quantum mechanics to monitor and study the motion of subatomic particles, but the picture in front of him was blurry and not clear, so he resorted to the probabilistic interpretation. <p class="card-text"><strong>Keywords:</strong> <a
