Based on the Krylov-Bogolyubov method of averaging the closed system of equations for particle motion and temperature in inhomogeneous rapidly oscillating velocity and temperature of fluid phase is derived. It is shown that the particle movement in a rapidly oscillating fluid velocity field occurs not only under the force of gravity and resistance, but also under force of migration. The migrati...

In the classical model of molecular adaptation, a favored allele derives from a single mutational origin. This ignores that beneficial alleles can enter a population recurrently, either by mutation or migration, during the selective phase. In this case, descendants of several of these independent origins may contribute to the fixation. As a consequence, all ancestral haplotypes that are linked ...

Recently there has been a growing interest in studying multiplex networks where individuals are structured in multiple network layers. Previous agent-based simulations of games on multiplex networks reveal rich dynamics arising from interdependency of interactions along each network layer, yet there is little known about analytical conditions for cooperation to evolve thereof. Here we aim to ta...

A computer program was created to conduct a comparative study of five Multi-Criteria Evaluation Methods (MCEMs), each of which is capable of evaluating alternatives in a resource management setting. The MCEMs included Weighted Average (WA), Preference Ranking Organization METHod for Enrichment Evaluations (PROMETHEE II), Compromise Programming (CP), ELimination and Choice Translating REality (E...

The Analytical Sciences Digital Library (ASDL) is a collection of electronic resources for teachers, students, and practitioners interested in chemical measurements and instrumentation. The ASDL collection is freely accessible at www. asdlib.org. This project has been funded by the National Science Foundation’s National Science Digital Library (NSDL) program. The NSDL (http://nsdl.org/) is an o...

the main objective of this research is investigating the performance of ravang’s rural – industrial area and its role in rural development, occupation and income, using available equipments, stabilizing rural population (preventing migration to cities), identifying positive and negative points of establishing and starting this plan and finally recognizing problems and providing suggestions....

What do you do to start reading analytical numerical and computational methods for science and engineering? Searching the book that you love to read first or find an interesting book that will make you want to read? Everybody has difference with their reason of reading a book. Actuary, reading habit must be from earlier. Many people may be love to read, but not a book. It's not fault. Someone w...

The reasons for replacing the classical strictly two-component velocity and equilibrium analytical ultracentrifugation Svedberg equations by multicomponent equations, applicable in the study of biological macromolecular systems, are given.

The global city thesis and the migration thesis concern two important dimensions of the impacts of contemporary globalization on cities. The two theses are intrinsically linked. The central question is how we should approach migration in the new context of the global city, and how we should articulate their interrelationships. To address this question, we construct an integrative analytical fra...
