The control problem and Dynamic programming is a powerful tool in economics and management. We review the dynamic programming problem from its beginning up to its present stages. A problem which was involved in physics and mathematics in I 7” century led to a branch of mathematics called calculus of variation which was used in economic, and management at the end of the first quarter of the 20” ...

So far, many scholars have spoken of mathematical and architectural mergers. Different perspectives in this regard suggest that there are two general approaches paraphrastic and historians in most of these studies. But what has not been said about this aspect is common mental practices in mathematical science and architecture knowledge that affects the work of mathematicians and past architects...

The present study is part of a bigger research project and its purpose was to investigate the influencing factors on integrating professional learning of secondary mathematics teachers with the ways in which they analyze, interpret and make decisions regarding their teaching. For the fine-grained analysis of the first layer of data, phenomenography method was used. Nine teachers were interviewe...

the analysis of the 27al and 35cl quadrupole coupling parameters of aluminum methyl chloride dimers were carried out on the basis of the density functional theory (dft). the available experimental values of quarupole coupling constants were compared with their calculated ones. in this investigation, the correlations were made between calculated 27al and 35cl nuclear quadrupole coupling constant...

Background and aim: Due to the importance of keywords in the field of research and scientometrics, the keywords used in scientific outputs of mathematics education specialists were investigated in this study to determine the scope of their research. Material and methods: This cross-sectional study was conducted on the Persian scientific papers published by mathematics education specialists who ...

We have first demonstrated that Debreu’s view regarding the publication of The Theory of Games and Economic Behavior by von Neumann and Morgenstern in 1944 as the birth of modern mathematical economics is not convincing. In this paper, we have proposed the hypothesis that the coordinated research programs in the 1930’s, initiated by the Econometric Society and the Cowles Commission for Research...

among the various interpretations of michelangelo’s moses, freud’s is well-known. the founder of psychoanalysis, freud reviews all the critics and interpretations of this masterpiece and then offers his own: this moses is not about to spring up, as claimed by others, but on the contrary, is sitting down, suppressing his “rage”. in the light of recent works of daniel arasse, art critic (study of...

In this paper we survey the topic of time-reversal symmetry in dynamical systems. We begin with a brief discussion of the position of time-reversal symmetry in physics. After defining time-reversal symmetry as it applies to dynamical systems, we then introduce a major theme of our survey, namely the relation of time-reversible dynamical sytems to equivariant and Hamiltonian dynamical systems. W...

  Charge symmetry breaking potentials due to the exchange of pseudoscalar and vector mesons in mirror nuclei are considered. With the computation of coulmb energy along with the present charge symmetry breaking effects provide a reasonably accurate description of the binding energy differences between mirror nuclei.
