In recent years there has been a growing interest in using stochastic time-dependent (STD) networks as a modelling tool for a number of applications within such areas as transportation and telecommunications. It is known that an optimal routing policy does not necessarily correspond to a path, but rather to a time-adaptive strategy. In some applications, however, it makes good sense to require ...

To introduce the advance in the researches on boiling and two-phase ‰ow in reduced gravity ˆelds and the change in the situation surrounding them in Japan, a short review is focused on the individual research subjects, i.e., pool boiling, ‰ow boiling, and unheated two-phase ‰ow including their major topics. Representative results obtained so far are introduced. Future direction of researches on...

We study voting games on possibly interconnected issues, where voters might hold a principled opinion about a subset of the issues at stake while willing to strike deals on the remaining ones, and can influence one another before casting their ballots in order to obtain an individually more favourable outcome. We analyse voters’ rational behaviour in a two-phase game, allowing players to underg...

According to the basic content of location advantage, from the market, transportation, competition environment and other factors, such as four aspects, analysis of location factors influencing express logistics node location. Put forward based on location factors evaluation and location advantages express logistics node location two-phase model of evaluation. An express logistics node location ...

Consider a system with n components (different types of molecules) with r phases in equilibrium. The state of each phase is defined by P, T and then (n− 1) concentration variables in each phase. The phase equilibrium at given P, T is defined by the equality of n chemical potentials between the r phases. Thus there are n(r − 1) constraints on (n− 1)r + 2 variables. This gives the Gibbs phase rul...

This paper is concerned with an inverse problem involving a two-phase moving boundary in two dimensional solidification of pure substance. Using a unique continuation result due to Saut and Schcurer we prove a uniqueness result. © 2005 Elsevier Ltd. All rights reserved.

The depth of field of optical systems can be extended with a phase mask placed in the pupil. We propose to design this phase mask through a heuristic numerical optimization. We describe two different criteria to illustrate the technique. We present the obtained phase profiles and we show that they have good properties regarding the extension of the depth of field.

In this paper we extend to three-phase flow the nonequilibrium formalism proposed by Barenblatt and co-workers for two-phase porous media flow. The underlying idea is to include nonequilibrium effects by introducing a pair of effective water and gas saturations, which are linked to the actual saturations by a local evolution equation. We illustrate and analyze how nonequilibrium effects lead to...
