KONSTRUKSI GELOMBANG KEJUT DAN GELOMBANG MENJARANG PADA ARUS KENDARAAN DI LALU LINTAS

open access: yesJurnal Lebesgue, 2023
In nonlinear conservation laws, there is a possibility of intersecting characteristic lines or even regions that are not traversed by characteristic lines. In regions where there are two or more characteristic lines, a gradien catastrophic phenomenon can

Conservation laws can be derived from field equations?

open access: yes, 2020
Charge conservation law ($\partial_{\beta} J^\beta =0$) usually is considered as a corollary of Maxwell's equations. A circular reasoning, however, is found in the derivation. A similar fallacy exists in the matter source's conservation law ($\nabla^{\mu}

A statistical conservation law in two and three dimensional turbulent flows [PDF]

open access: yes, 2015
Particles in turbulence live complicated lives. It is nonetheless sometimes possible to find order in this complexity. It was proposed in [Falkovich et al., Phys. Rev. Lett.

SYMMETRY AND CONSERVATION LAWS [PDF]

open access: yesProceedings of the National Academy of Sciences, 1964
Symmetry and invariance considerations, and even conservation laws, played undoubtedly an important role in the thinking of the early physicists, such as Galileo and Newton, and probably even before then. However, these considerations were not thought to be particularly important and were articulated only rarely.

Symmetries of conservation laws [PDF]

open access: yesPublications de l'Institut Mathematique, 2005
We apply techniques of symmetry group analysis in solving two systems of conservation laws: a model of two strictly hyperbolic conservation laws and a zero pressure gas dynamics model, which both have no global solution, but whose solution consists of singular shock waves.

Fluctuations and Conservation Laws [PDF]

open access: yesActa Physica Polonica B Proceedings Supplement, 2021
Author(s): Koch, V; Vovchenko, V; Poberezhnyuk, RV | Abstract: We report on recent progress concerning effects of global conservation laws on cumulants of conserved quantities. Specifically, we will relate for an arbitrary equation of state cumulants of a conserved charge measured in a subvolume of a thermal system with the corresponding grandcanonical

Dynamics of Coupled Maps with a Conservation Law [PDF]

open access: yes, 1997
A particularly simple model belonging to a wide class of coupled maps which obey a local conservation law is studied. The phase structure of the system and the types of the phase transitions are determined.

Lie Symmetry Group, Invariant Subspace, and Conservation Law for the Time-Fractional Derivative Nonlinear Schrödinger Equation

open access: yesMathematics, 2022
In this paper, a time-fractional derivative nonlinear Schrödinger equation involving the Riemann–Liouville fractional derivative is investigated. We first perform a Lie symmetry analysis of this equation, and then derive the reduced equations under the ...

Conservation Laws and Hydrodynamics

open access: yesEPJ Web of Conferences, 2023
Recent years have seen much development in analyzing the structure of relativistic hydrodynamics. In this proceeding, some of the developments are highlighted including issues related to pseudo-gauge transformations and spin hydrodynamics.
