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.

Inquisitive bisimulation

open access: yes, 2018
Inquisitive modal logic InqML is a generalisation of standard Kripke-style modal logic. In its epistemic incarnation, it extends standard epistemic logic to capture not just the information that agents have, but also the questions that they are ...

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.

Kripke Semantics and Proof Systems for Combining Intuitionistic Logic and Classical Logic [PDF]

open access: yes, 2013
International audienceWe combine intuitionistic logic and classical logic into a new, first-order logic called Polarized Intuitionistic Logic. This logic is based on a distinction between two dual polarities which we call red and green to distinguish ...

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

open access: yesAdvanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

A Syntactic Proof of the Decidability of First-Order Monadic Logic

open access: yesBulletin of the Section of Logic
Decidability of monadic first-order classical logic was established by Löwenheim in 1915. The proof made use of a semantic argument and a purely syntactic proof has never been provided.
