Numerical simulation of complicated grains with 3D burnback and Quasi-One-Dimensional flow field of solid rocket motors [PDF]
فصلنامه علوم و فناوری فضایی, 2019 In this research, the 3D grain burnback with quasi-one-dimensional internal ballistic in a solid rocket motor is simulated using the Level set theory and the utilization of Sections method, while achieving high accuracy in the simulation of green's post ...

CONSTRUCTING NONSTANDARD HULLS AND LOEB MEASURES IN INTERNAL SET THEORIES
The Bulletin of Symbolic Logic, 2022 AbstractCurrently the two popular ways to practice Robinson’s nonstandard analysis are the model-theoretic approach and the axiomatic/syntactic approach. It is sometimes claimed that the internal axiomatic approach is unable to handle constructions relying on external sets.

Evolution of the CSDP in the setting of European integration and international relations theory [PDF]
Comparative Strategy, 2022 The Common Security and Defense Policy (CSDP) represents an institutionalizedattempt by European Union Member States to respondto the security challenges they confront. This paper discusses theevolution of this policy through the lens of political integration andinternational relations theories.

Mathematics, 2022 The theory of finitely supported structures is used for dealing with very large sets having a certain degree of symmetry. This framework generalizes the classical set theory of Zermelo-Fraenkel by allowing infinitely many basic elements with no internal ...

Spectral methods for internal waves: indistinguishable density profiles and double-humped solitary waves [PDF]
Nonlinear Processes in Geophysics, 2011 Internal solitary waves are widely observed in both the oceans and large lakes. They can be described by a variety of mathematical theories, covering the full spectrum from first order asymptotic theory (i.e.

On Hilbert's tenth problem: Is classical set theory inconsistent? [PDF]
, 2021 We consider cartesian categorical (free-variables) theory PR of primitive recursion and arithmetise (gödelise) it into the natural numbers set of a classical set theory T: We evaluate the map codes of the coded theory by a general recursive T map and ...

Solution of High Dimension Multi-objective Optimization Problem Based on Entropy and Membership Function [PDF]
Jisuanji gongcheng, 2016 A new fitness assignment strategy is proposed for solving the high dmension multi-objective optimization problem,which is the Fuzzy Relevance Entropy Method(FREM).The FREM is built by integrating the fuzzy information entropy theory and the membership ...

Set Theory and Structures [PDF]
, 2018 Set-theoretic and category-theoretic foundations represent different perspectives on mathematical subject matter. In particular, category-theoretic language focusses on properties that can be determined up to isomorphism within a category, whereas set ...
