On a Model of Phase Relaxation for the Hyperbolic Stefan Problem
In this paper we propose and study the nonlinear model for phase transition phenomena given by ∂t(θ + χ) + div q = f in Q := Ω×]0, T [, (1.1) α∂tq + q = −∇θ in Q, (1.2) ε∂tχ + χ ∈ γ(θ) in Q. (1.3) Here Ω is a bounded domain in R, T > 0 is a final time, and θ, χ : Q −→ R, q : Q −→ R are the unknown functions of the problem. The symbols ∂t, div , and∇ represent respectively the time derivative, t...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Nonlinear Two-Phase Stefan Problem
In this paper we consider a nonlinear two-phase Stefan problem in one-dimensional space. The problem is mapped into a nonlinear Volterra integral equation for the free boundary.
متن کاملa study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
