In order to clarify common assumptions on the form of energy and momentum in elasticity, a generalized conservation format is proposed for finite elasticity, in which total energy and momentum are not specified a priori. Velocity, stress, and total energy are assumed to depend constitutively on deformation gradient and momentum in a manner restricted by a dissipation principle and certain mild ...

der the assumption that secondary decay vertices exhibit amplitude interference at fixed space-time points) that for π − + p + → Λ + K 0 Lambda oscillations disappear. Under the same assumption, we find that conservation of energy and conservation of momentum also disappear. Quantum oscillations occur for quite ordinary particles for reasons which are discussed. In two particle " in " and two p...

in this paper, a study and design of energy conservation actions and the obtention of energy efficiency titles, according to the italian ministerial decree 20th july 2004, applied to lighting and electrical systemsin a school district managed by perugia province (italy), is presented.specifically, the analysis regarded the replacement of neon lamps with high efficiency ones, and the power facto...

This paper discusses a connection between scalar convex conservation laws and Pontryagin’s minimum principle. For flux functions for which an associated optimal control problem can be found, a minimum value solution of the conservation law is proposed. For scalar space-independent convex conservation laws such a control problem exists and the minimum value solution of the conservation law is eq...

modeling and simulation of processing plants are widely used in industry. construction of a mathematical model for a plant is a time-consuming and error-prone task. in light of extensive advancements in computer science (both hardware and software), computers are becoming a necessary instrument in industrial activities. many software tools for modeling, simulation and optimization of processing...

The unsmooth boundary will greatly affect motion morphology of a shallow water wave, and a fractal space is introduced to establish a generalized KdV-Burgers equation with fractal derivatives. The semi-inverse method is used to establish a fractal variational formulation of the problem, which provides conservation laws in an energy form in the fractal space and possible solution structures of t...

Schools play a vital role in creating a greener future. They will likely be the first place most students encounter determined efforts to conserve energy and water or to reduce waste. The method used in this article is comparative and matching method, by using ISO 14001, OHSAS 18001 and ISO 50001 standards.  Implementing energy management along with other standards is the main objective of pres...
