Time decay for porosity problems

چکیده
In this paper, we numerically study porosity problems with three different dissipation mechanisms. The root behavior is analyzed for each case. Then, by using the finite element method and Newmark-β scheme, fully discrete approximations are introduced some numerical results described to show energy evolution depending on viscosity coefficient.

Development of a Genetic Algorithm for Advertising Time Allocation Problems
Commercial advertising is the main source of income for TV channels and allocation of advertising time slots for maximizing broadcasting revenues is the major problem faced by TV channel planners. In this paper, the problem of scheduling advertisements on prime-time of a TV channel is considered. The problem is formulated as a multi-unit combinatorial auction based mathematical model. This is a...
متن کاملA variational approach to double-porosity problems
In this paper we outline an approach by Γ-convergence to some problems related to ‘double-porosity’ homogenization. Various such models have been discussed in the mathematical literature, the first rigorous result for a linear double-porosity model having been obtained by Arbogast, Douglas and Hornung in [7]. The two-scale convergence approach to double-porosity problems was developed by Allair...
متن کاملPolynomial-Time Rademacher Theorem, Porosity and Randomness
The main result of this paper is a polynomial time version of Rademacher’s theorem. We show that if z ∈ R is p-random, then every polynomial time computable Lipschitz function f : R → R is differentiable at z. This is a generalization of the main result of [19]. To prove our main result, we introduce and study a new notion, p-porosity, and prove several results of independent interest. In parti...
متن کاملA Mathematical Programming Model for Flow Shop Scheduling Problems for Considering Just in Time Production
In this paper, we consider a flow shop scheduling problem with bypass consideration for minimizing the sum of earliness and tardiness costs. We propose a new mathematical modeling to formulate this problem. There are several constraints which are involved in our modeling such as the due date of jobs, the job ready times, the earliness and the tardiness cost of jobs, and so on. We apply adapte...
متن کاملPorosity of perturbed optimization problems in Banach spaces ✩
Let X be a Banach space and Z a nonempty closed subset of X. Let J :Z → R be a lower semicontinuous function bounded from below. This paper is concerned with the perturbed optimization problem infz∈Z{J (z)+ ‖x − z‖}, denoted by (x, J )-inf for x ∈X. In the case when X is compactly fully 2-convex, it is proved in the present paper that the set of all points x in X for which there does not exist ...
