Study on intelligent analysis algorithm for achieving standard of polymer flooding well group [PDF]

open access: yesE3S Web of Conferences, 2022
In order to master the development effect of polymer flooding well group, it is necessary to accurately analyze the influence of different factors in the whole polymer flooding process on the development index.

A rough set approach for determining weights of decision makers in group decision making. [PDF]

open access: yesPLoS ONE, 2017
This study aims to present a novel approach for determining the weights of decision makers (DMs) based on rough group decision in multiple attribute group decision-making (MAGDM) problems.

Rough Groups over Rough Sets

open access: yesTürk Doğa ve Fen Dergisi, 2023
In this study the rough algebraic structure especially on rough group is focused. The author make over the inadequate definition of rough group of an approximation space. Here, the rough groups over the rough sets is defined, in the sense of Pawlak's rough sets. Later, the structure of rough groups is given.

Reconstruction for the Signature of a Rough Path [PDF]

open access: yes, 2016
Recently it was proved that the group of rough paths modulo tree-like equivalence is isomorphic to the corresponding signature group through the signature map S (a generalized notion of taking iterated path integrals).

First record of a white rough-toothed dolphin (Steno bredanensis) off West Africa including notes on rough-toothed dolphin surface behaviour [PDF]

open access: yes, 2010
In June 2009, a white rough-toothed dolphin (Steno bredanensis) calf was photographed in a group of at least 50 dolphins in the southern Gulf of Guinea, 95 nauticol miles off the Gabon coast (01°45'S 007°29'E), West Africa. Reports of unusually pigmented

Study on Chaotic Multi-Attribute Group Decision Making Based on Weighted Neutrosophic Fuzzy Soft Rough Sets

open access: yesMathematics, 2023
In this article, we have proposed a multi-attribute group decision making (MAGDM) with a new scenario or new condition named Chaotic MAGDM, in which not only the weights of the decision makers (DMs) and the weights of the decision attributes are ...

Radiative Transfer in a Discrete Random Medium Adjacent to a Half-Space with a Rough Interface [PDF]

open access: yes, 2018
For a macroscopically plane-parallel discrete random medium, the boundary conditions for the specific coherency dyadic at a rough interface are derived.

Partial associativity and rough approximate groups [PDF]

open access: yesGeometric and Functional Analysis, 2020
AbstractSuppose that a binary operation $$\circ $$ ∘ on a finite set X is injective in each variable separately and also associative. It is easy to prove that $$(X,\circ )$$ ( X , ∘ ) must be a group. In this paper we examine what happens if one knows only that a positive proportion of the triples $$(x,y,z)\in X^3$$ ( x , y , z ) ∈ X 3 ...
