Definability And Textures
(Elsevier Science Inc, 2012)
This paper aims to give a new perspective for definability in rough set theory. First, a counterpart of definability is introduced in textural approximation spaces. Then a complete field of sets for texture spaces is defined ...
Ditopological Texture Spacesand Intuitionistic Sets
(Elsevier Science Bv, 1998)
In this paper it is shown that the lattice of intuitionistic subsets of a set X in the sense of D. Coker may be represented as a special type of texture space, called an intuitionistic texture on X, and various characterizations ...
Categories of Rough Sets and Textures
(Elsevier Science Bv, 2013)
It is known that the theories of rough sets and fuzzy sets have successful applications in computing. Textures, as a theoretical model, provide a new perspective for both rough sets and fuzzy sets. Indeed, recent papers ...
A Category Approach to Relation Preserving Functions in Rough Set Theory
(Elsevier Science Inc, 2015)
The category Rel whose objects are all pairs (U, r), where r is a relation on a universe U, and whose morphisms are relation-preserving mappings is a canonical example in category theory. One of the convenient categories ...
Di-Uniformities and Hutton Uniformities
(Elsevier Science Bv, 2012)
The authors characterize di-uniformities on a texture (S, J) in the sense of Ozgag and Brown (Di-uniform texture spaces, Appl. Gen. Top. 4(1) (2003), 157-192) in terms of functions on the texturing J. This characterization ...
Nearly Perfect Sequences With Arbitrary Out-Of-Phase Autocorrelation
(Amer Inst Mathematical Sciences-Aims, 2016)
A sequence of period n is called a nearly perfect sequence of type gamma if all out-of-phase autocorrelation coefficients are a constant gamma. In this paper we study nearly perfect sequences (NPS) via their connection to ...
A New Multilayer Feedforward Network Based on Trimmed Mean Neuron Model
(Acad Sciences Czech Republic, Inst Computer Science, 2015)
The multilayer perceptron model has been suggested as an alternative to conventional approaches, and can accurately forecast time series. Additionally, several novel artificial neural network models have been proposed as ...
An Analytic Shooting-Like Approach For The Solution of Nonlinear Boundary Value Problems
(Pergamon-Elsevier Science Ltd, 2011)
In this paper a novel approach is presented for an analytic approximate solution of nonlinear differential equations with boundary conditions. By converting the nonlinear problem into an initial value form, a shooting-like ...
Further Results On Fibre Products Of Kummer Covers And Curves With Many Points Over Finite Fields
(Amer Inst Mathematical Sciences-Aims, 2016)
We study fibre products of an arbitrary number of Kummer covers of the projective line over F-q under suitable weak assumptions. If q - 1 = r(n) for some prime r, then we completely determine the number of rational points ...
Hybrid Non-Dominated Sorting Genetic Algorithm With Adaptive Operators Selection
(Elsevier Science Bv, 2017)
Multiobjective optimization entails minimizing or maximizing multiple objective functions subject to a set of constraints. Many real world applications can be formulated as multi-objective optimization problems (MOPs), ...
