In this paper, we investigate a Bresse-type system of thermoelasticity of type III in the presence of a distributed delay. We prove the well-posedness of the problem. Furthermore, an exponential stability result will be shown without the usual assumption on the wave speeds. To achieve our goals, we make use of the semigroup method and the energy method.
We report measurements of intrinsic dissipation in micron-sized suspended resonators machined from single crystals of galium arsenide and silicon. In these experiments on high-frequency micromechanical resonators, designed to understand intrinsic mechanisms of dissipation, we explore dependence of dissipation on temperature, magnetic field, frequency, and size. In contrast to most of the previo...
Abstract In this paper, we consider the energy decay of some problems involving domains with radial symmetry. Three different settings are studied: a strong porous dissipation and heat conduction, weak conduction poro-thermoelasticity microtemperatures. all three problems, exponential is shown. Moreover, for each them finite element simulations presented to numerically demonstrate behavior.
hydraulics of stepped spillway is a very complicated phenomenon, as it consists of a two phase flow passing through a set of designed steps. the steps increase the rate of energy dissipation taking place on the spillway face. turbulence, flow aeration and energy dissipation are the main tasks in the design of such structures. this study consists of the experimental investigation to determine th...
