This is a survey on the usage of the module theoretic notion of a “retractable module" in the study of algebras with actions. We explain how classical results can be interpreted using module theory and end the paper with some open questions.

Complex Event Processing (CEP) deals with processing of continuously arriving events with the goal of identifying meaningful patterns (complex events). In existing stream database approaches, CEP is manly concerned by temporal relations between events. This paper advocates for a knowledge-rich CEP with Stream Reasoning capabilities. Secondly, we address the problem of revision in event processi...

Abstract The literature on the metaphysics of gender is partially marked by a tension between conceptions that understand categories as importantly at least partly self-determined identities and those them social or cultural imposed upon others tool oppression. I argue this can be mediated understanding essentially contested. then draw “radical functionalism” to that, while, divorced context, c...

This study investigated the wind pressure characteristics of an elliptical plan retractable dome roof. Wind tunnel experiments were performed on roofs with varying wall height-to-span ratios (0.1–0.5) and opening (0, 10, 30, 50 %), where ratio was defined as open area roof to total The resulting peak coefficients closed then compared those Japanese load code (AIJ-RLB (2015)) there are no curren...

This is a survey of essentially normal operators and related developments. There is an overview of Weyl–von Neumann theorems about expressing normal operators as diagonal plus compact operators. Then we consider the Brown–Douglas–Fillmore theorem classifying essentially normal operators. Finally we discuss almost commuting matrices, and how they were used to obtain two other proofs of the BDF t...
