the continuum based approaches don’t provide the correct physics in atomic scales. on the other hand, the molecular based approaches are limited by the length and simulated process time. as an attractive alternative, this paper proposes the fixed interfacial multiscale method (fimm) for computationally and mathematically efficient modeling of solid structures. the approach is applicable to mult...

this article presents a growth model consistent with economic situation of iran. various sectors of the economy are expressed by certain behavioral equations. the suggested model, is designed to incorporate findings of the leading theories of economic growth (harrod domar) models, lewis structural change theory, and the solow growth model. the model is calibrated using statistical data from ira...

The following propositions are true: (1) Let X be a set, p be a permutation of X, and x, y be elements of X. Then p +· (x, p(y)) +· (y, p(x)) is a permutation of X. (2) Let f be a function and x, y be sets. Suppose x ∈ dom f and y ∈ dom f. Then there exists a permutation p of dom f such that f +· (x, f(y)) +· (y, f(x)) = f · p. Let X be a finite non empty subset of R. The functor minX yielding ...

In this paper, a macro-model of the proton exchange membrane fuel cell (PEMFC) stack is proposed. A comparative study is made by simulation for the proposed PEMFC macro-model and a reported PEMFC impedance model, which use for PEMFC dynamic a transfer function and an electrical circuit, respectively. The macro-model approximates the theoretical PEMFC current–voltage characteristic by a controll...

in some of the new economic growth models, we pay attention to the effects of financial development on economic growth. this research investigates the relationship between capital market and economic growth in macro level during 1991-2011. the research is organized as follows: the introduction comes as the first section. in section ii, we review the literature on the relationship between econom...

(1) For every macro instruction I and for every integer location a holds card(if a = 0 then I; Goto(insloc(0)) else (StopSCMFSA)) = card I +6. (2) For every macro instruction I and for every integer location a holds card(if a > 0 then I; Goto(insloc(0)) else (StopSCMFSA)) = card I +6. Let a be an integer location and let I be a macro instruction. The functor while a = 0 do I yields a macro inst...

This paper describes a comparison of the well known Active Shape Model (ASM) and the new More Active Shape Model (MASM). It is the first time MASM has been implemented and thus also the first time it has been compared to ASM. Both implementations were done in Matlab and the comparison were done on a real case of finding the metacarpals in x-ray images of the left hand. The paper also introduces...
