Agents and rough sets [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2014
Rough set theory gives approximation models of complex knowledge structure. Agents are not present in the definition of the rough sets. Now we will show that a set of conflicting agents or active set can be used to model inconsistent decision in rough ...

Fuzzy ideals and fuzzy congruences of co-residuated lattices [PDF]

open access: yesJournal of Hebei University of Science and Technology
In order to expand the theory of fuzzy logic algebra, the fuzzy ideals and fuzzy congruences of co-residuated lattices and their interrelationships were studied.

Collective modes of vortex lattices in two-component Bose–Einstein condensates under synthetic gauge fields

open access: yesNew Journal of Physics, 2019
We study collective modes of vortex lattices in two-component Bose–Einstein condensates subject to synthetic magnetic fields in mutually parallel or antiparallel directions. By means of the Bogoliubov theory with the lowest-Landau-level approximation, we

Neutrosophic Multigroups and Applications

open access: yesMathematics, 2019
In recent years, fuzzy multisets and neutrosophic sets have become a subject of great interest for researchers and have been widely applied to algebraic structures include groups, rings, fields and lattices.

Higher-Order Theories for Doubly Curved Laminated Lattice and Honeycomb Structures [PDF]

open access: yes14th WCCM-ECCOMAS Congress, 2021
A collocation model based on a Generalized Differential Quadrature Method (GDQM) is proposed for the dynamic analysis of anisotropic curved laminated structures with a central lattice core and different external constraints. The theory is based on the Equivalent Single Layer (ESL) approach, together with higher-order kinematic assumptions.

Fuzzy Soft Sets and Fuzzy Soft Lattices [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2012
The theory of soft sets was introduced by Molodtsov in 1999 in order to deal with uncertainties. In this paper, the notion of fuzzy soft lattice is defined and some related properties are derived, which extends the notion of a fuzzy lattice to include ...

Minimal Generators from Positive and Negative Attributes: Analysing the Knowledge Space of a Mathematics Course

open access: yesInternational Journal of Computational Intelligence Systems, 2022
Formal concept analysis is a data analysis framework based on lattice theory. In this paper, we analyse the use, inside this framework, of positive and negative (mixed) attributes of a dataset, which has proved to represent more information on the use of

Toughness enhancement of honeycomb lattice structures through heterogeneous design

open access: yesMaterials & Design, 2022
Inspired by the microstructures feature in the architected composites, which are consisted of a stiff phase and a soft phase, the concept of varying the struts thickness in the uniform honeycomb (UH) is proposed to enhance the toughness of UH structures ...
