Mathematics, 2020 The fuzzyfication of hypercompositional structures has developed in several directions. In this note we follow one direction and extend the classical concept of reducibility in hypergroups to the fuzzy case.

The weakness of being cohesive, thin or free in reverse mathematics [PDF]
, 2016 Informally, a mathematical statement is robust if its strength is left unchanged under variations of the statement. In this paper, we investigate the lack of robustness of Ramsey's theorem and its consequence under the frameworks of reverse mathematics ...

Infinite time Turing machines and an application to the hierarchy of equivalence relations on the reals [PDF]
, 2009 We describe the basic theory of infinite time Turing machines and some recent developments, including the infinite time degree theory, infinite time complexity theory, and infinite time computable model theory. We focus particularly on the application of

Effects of Different Loadings of Ru and Re on Physico-Chemical Properties and Performance of 15% Co/Al2O3 FTS Catalysts [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2005 An extensive study of Fischer-Tropsch synthesis (FTS) on alumina-supported cobalt catalysts promoted with different amounts of ruthenium and rhenium is reported. Up to 2 wt% of promoters, are added to the catalyst by coimpregnation.

Borel and countably determined reducibility in nonstandard domain
, 2002 We consider reducibility of equivalence relations (ERs, for brevity), in a nonstandard domain, in terms of the Borel reducibility and the countably determined (CD, for brevity) reducibility.

, 2015 Continuous-domain visual signals are usually captured as discrete (digital) images. This operation is not invertible in general, in the sense that the continuous-domain signal cannot be exactly reconstructed based on the discrete image, unless it ...

Reducibility of beam equations in higher-dimensional spaces
Boundary Value Problems, 2017 In this paper, we reduce a linear d-dimensional beam equation with an x-periodic and t-quasi-periodic potential for most values of the frequency vector via the KAM theorem.

Resilient Reducibility in Nuclear Multifragmentation
, 1999 The resilience to averaging over an initial energy distribution of reducibility and thermal scaling observed in nuclear multifragmentation is studied. Poissonian reducibility and the associated thermal scaling of the mean are shown to be robust. Binomial

Kinetics of reduction and oxidation reactions during pyrometallurgical metal extraction [PDF]
, 2017 The article deals with a sophisticated approach to the study of basic kinetic dynamic process in metal production. It is concerned with three agendas: study of reduction reactions of iron oxides and carbon as reducing agents with secondary created oxides;
