Superdeduction in Lambda-Bar-Mu-Mu-Tilde [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2011
Superdeduction is a method specially designed to ease the use of first-order theories in predicate logic. The theory is used to enrich the deduction system with new deduction rules in a systematic, correct and complete way.

Classical and fuzzy logic evaluation of students' master theses in Matlab Fuzzy Logic Toolbox software: Dealing with subjectivity in human reasoning [PDF]

open access: yesAgroznanje, 2018
The two-level evaluation of defined objectives, presented materials and methods and interpretation of results in master theses was done, in order to estimate their scientific contribution and statistical relevance. First level of evaluation was performed

Towards depth-bounded natural deduction for classical first-order logic [PDF]

open access: yes, 2021
Summary: In this paper we lay the foundations of a new proof-theory for classical first-order logic that allows for a natural characterization of a notion of inferential depth. The approach we propose here aims towards extending the proof-theoretical framework presented by \textit{M. D'Agostino} et al. [Stud. Log. 108, No.

Tableau Systems for Epistemic Positional Logics

open access: yesBulletin of the Section of Logic, 2021
The goal of the article is twofold. The first one is to provide logics based on positional semantics which will be suitable for the analysis of epistemic modalities such as ‘agent ... knows/beliefs that ...’.

Aristotelian logic and its perspectives

open access: yesPensamiento. Revista de Investigación e Información Filosófica, 2017
The legitimacy of Aristotelian logic was questioned in the twentieth century. As a result, the question of whether it should be replaced or restored remains unanswered.

Classical System of Martin-Lof's Inductive Definitions is not Equivalent to Cyclic Proofs [PDF]

open access: yesLogical Methods in Computer Science, 2019
A cyclic proof system, called CLKID-omega, gives us another way of representing inductive definitions and efficient proof search. The 2005 paper by Brotherston showed that the provability of CLKID-omega includes the provability of LKID, first order ...

An Integrated First-Order Theory of Points and Intervals over Linear Orders (Part II) [PDF]

open access: yesLogical Methods in Computer Science, 2020
There are two natural and well-studied approaches to temporal ontology and reasoning: point-based and interval-based. Usually, interval-based temporal reasoning deals with points as a particular case of duration-less intervals.

Herbrand-Confluence [PDF]

open access: yesLogical Methods in Computer Science, 2013
We consider cut-elimination in the sequent calculus for classical first-order logic. It is well known that this system, in its most general form, is neither confluent nor strongly normalizing.

Preuves et jeux sémantiques

open access: yesPhilosophia Scientiæ, 2004
Hintikka makes a distinction between two kinds of games: truthconstituting games and truth-seeking games. His well-known game-theoretical semantics for first-order classical logic and its independence-friendly extension belongs to the first class of ...

Comparative Study of Temperature Control in a Heat Exchanger Process [PDF]

open access: yesEngineering and Technology Journal, 2012
In the present work the dynamic behavior of a plate heat exchanger (PHE) (single pass counter current consists of 24 plates) studied experimentally and theoretically to control the system.
