Speaker: Horia Velicu (BRD – Groupe Societe Generale)
Abstract: Presentation of topics of interest for 2020, objectives and data available at BRD. Proposals for the themes for the applied research institute that will be sponsored this year. Presentation of the new BRD AI Hub.
Speaker: Marian Calborean (University of Bucharest)
Abstract: The Sorites paradox is usually studied as a propositional paradox. However, the general form of the Sorites is second-order, with three main features. It doesn’t contain any arbitrary parameters. It can be used to generate the propositional Sorites by appropriate replacement of the second-order premise with arbitrary clauses. Finally, it is generally nonfirstorderizable, relying on the notion of transitive closure of a relation. However, it can be expressed in FOL with a finite upper bound on the elements of the relation. This leads to a definition of vagueness in classical FOL, using the interplay between a total preorder and a monadic predicate. A notational extension of FOL will introduce a vague structure formed by the predicate (e.g.tall), the broad predicate (e.g. broadly tall) and the strict predicate (e.g. strictly tall). It allows the failure of a weak non-contradiction (e.g. ‘Some men are both broadly tall and broadly short’), the failure of a weak LEM (e.g. ‘Some men are neither strictly tall nor strictly short`), and the truth of a non-paradoxical tolerance (e.g. ‘If a person of n cm is strictly tall, a person of n-1 cm is broadly tall’).

Title: Off-the-Record Communication (OTR)
Speaker: Mihail-Iulian Plesa
Abstract: Off-the-Record Communication (OTR) este un protocol care modealeaza o discutie dintre doua entitati, care ar trebui sa satisfaca anumite proprietati de securitate. Vom vorbi despre proprietatile acestui tip de comunicatie si despre cum pot fi acestea implementate in mediul online. Vom discuta apoi despre protocolul OTR integrat in Signal si cum anume difera acesta fata de versiunea originala.
Nota: Prezentarea va fi urmata de o sesiune de joc CryptoGo – joc de carti educational pentru criptografie.
