Wettability of the System of Cast Iron and Magnesia Ceramics with Graphite [PDF]

open access: yesArchives of Foundry Engineering, 2022
In this paper examinations of high-temperature wetting tests of 3 systems of liquid alloy – cast iron in contact with ceramic materials: magnesia ceramics in combination with natural graphite were presented.

Abstract objects: Species, Kinds, Concepts [PDF]

open access: yes, 2016
In the paper I present Kotarbiński’s approach to abstract objects and show some mistakes in his investigations. By formal ontology I try to explain Kotarbiński’s view and proffer a new solution, a formal solution that is – I hope – in the spirit of Lvov ...

Kripke Semantics for Intuitionistic Łukasiewicz Logic

open access: yesStudia Logica: An International Journal for Symbolic Logic, 2020
This paper proposes a generalization of the Kripke semantics of intuitionistic logic IL appropriate for intuitionistic Łukasiewicz logicIŁL —a logic in the intersection between IL and (classical) Łukasiewicz logic.

On the Mutual Definability of the Notions of Entailment, Rejection, and Inconsistency [PDF]

open access: yes, 2016
In this paper, two axiomatic theories T− and T′ are constructed, which are dual to Tarski’s theory T+ (1930) of deductive systems based on classical propositional calculus.

Tableaux for Maximum Satisfiability in Łukasiewicz Logic

open access: yesIEEE International Symposium on Multiple-Valued Logic, 2020
We define a tableau calculus for solving the MaxSAT problem of 3-valued Łukasiewicz logic, and prove its soundness and completeness. The calculus can be naturally extended to other finitely-valued logics.

Between Contingency and Necessity of Human Action. Are We Free in our Choices? [PDF]

open access: yes, 2016
The point of departure of this paper is the characterization of human action as contingent or necessary (obligatory). The key question concerns the place for choice in the human action, i.e. are we free in our choices?

Maximality in finite-valued Łukasiewicz logics defined by order filters [PDF]

open access: yesJournal of Logic and Computation, 2018
In this paper we consider the logics $L_n^i$ obtained from the (n+1)-valued Lukasiewicz logics $L_{n+1}$ by taking the order filter generated by i/n as the set of designated elements.

Statistical relational learning with soft quantifiers [PDF]

open access: yes, 2016
Quantification in statistical relational learning (SRL) is either existential or universal, however humans might be more inclined to express knowledge using soft quantifiers, such as ``most'' and ``a few''.
