An application of operational modal analysis in modal filtering
Journal of Physics: Conference Series, 2011 Modal filtration in the field of damage detection has many advantages, including: its autonomous operation (without the interaction of qualified staff), low computational cost and low sensitivity to changes in external conditions. However, the main drawback of this group of damage detection methods is its limited applicability to operational data.

Completeness of Flat Coalgebraic Fixpoint Logics
, 2010 Modal fixpoint logics traditionally play a central role in computer science, in particular in artificial intelligence and concurrency. The mu-calculus and its relatives are among the most expressive logics of this type.

Operators or restrictors? A reply to Gillies
Semantics and Pragmatics, 2011 According to operator theories, "if" denotes a two-place operator. According to restrictor theories, "if" doesn't contribute an operator of its own but instead merely restricts the domain of some co-occurring quantifier.

Questions and Answers about Oppositions [PDF]
, 2011 A general characterization of logical opposition is given in the present paper, where oppositions are defined by specific answers in an algebraic question-answer game. It is shown that opposition is essentially a semantic relation of truth values between

Logic TK: Algebraic Notions from Tarski’s Consequence Operator
Principia: An International Journal of Epistemology, 2010 Tarski presented his definition of consequence operator to explain the most important notions which any logical consequence concept must contemplate. A Tarski space is a pair constituted by a nonempty set and a consequence operator.
