The first-order theory of ordering constraints over feature trees [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2001
The system FT ≤ of ordering constraints over feature trees has been introduced as an extension of the system FT of equality constraints over feature trees.

Open Descendants of Non-Diagonal Invariants [PDF]

open access: yes, 1999
The open descendants of simple current automorphism invariants are constructed. We consider the case where the order of the current is two or odd. We prove that our solutions satisfy the completeness conditions, positivity and integrality of the open and

A Finitely Axiomatized Non-Classical First-Order Theory Incorporating Category Theory and Axiomatic Set Theory

open access: yesAxioms, 2021
It is well known that Zermelo-Fraenkel Set Theory (ZF), despite its usefulness as a foundational theory for mathematics, has two unwanted features: it cannot be written down explicitly due to its infinitely many axioms, and it has a countable model due ...

FANS’ (ESTH)ET(H)ICS ELABORATION: POACHING AS TRUE LOVE PRACTICE [PDF]

open access: yesRAE: Revista de Administração de Empresas, 2022
The current study takes the subculture of fans as being the core of productive consumers, and assumes consumption to be a subjectivation practice based on Foucault's theory, which defines subjectivity as the result of an ethical and aesthetic elaboration

Percolation model of combustion

open access: yesMATEC Web of Conferences, 2018
Strong dependencies in equations cause dramatic boost of reaction rates in some rare but meaningful areas of a combustion gap. That leads to intermittent behavior of some values and for these reasons averaging approaches in calculations are not relevant.
