Information Sciences, 2021 The present paper proposes a novel way to unify Rough Set Theory and Formal Concept Analysis. Our method stems from results and insights developed in the algebraic theory of modal logic, and is based on the idea that Pawlak's original approximation spaces can be seen as special instances of enriched formal contexts, i.e.

SSRN Electronic Journal, 2014 Estimating volatility from recent high frequency data, we revisit the question of the smoothness of the volatility process. Our main result is that log-volatility behaves essentially as a fractional Brownian motion with Hurst exponent H of order 0.1, at any reasonable time scale.

ROUGH RINGS, ROUGH SUBRINGS, AND ROUGH IDEALS
Journal of Fundamental Mathematics and Applications (JFMA), 2022 The basic concept in algebra that is set theory can be expanded into rough sets. Basic operations on the set such as intersections, unions, differences, and complements can still apply to rough sets. In addition, one of the applications of rough sets is the use of rough matrices in decision making.

Corrosion-erosion processes of the AA 5083 (Al-Mg) alloy in seawater
Ciencias Marinas, 2003 Fourier Transforms are applied to analyse surface roughness profiles recorded on samples coming from corrosion-erosion assays. The information retrieved using this method clearly complements that revealed by the more classical roughness amplitude ...
