On the Pythagorean triangles with an irrational hypotenuse [PDF]

open access: yesMathematics and Computational Sciences, 2022
The paper investigates a number of incomplete exact roots of a series of natural numbers, in relation to the Pythagorean theorem that in a right-angled triangle the square of the hypotenuse is equal to the sum of the squares of the legs. It uses the fact

FUZZY INFERENCE SYSTEMS BASE ON POLYNOMIAL CONSEQUENTS OF FUZZY RULES [PDF]

open access: yesScientific Journal of Astana IT University, 2020
Various fuzzy inference systems that operate on the basis of polynomial consequents of fuzzy rules. As well as inference methods for such systems, in particular, Takagi-Sugeno fuzzy inference systems, their differences from other popular fuzzy systems ...

Dist-YOLO: Fast Object Detection with Distance Estimation

open access: yesApplied Sciences, 2022
We present a scheme of how YOLO can be improved in order to predict the absolute distance of objects using only information from a monocular camera. It is fully integrated into the original architecture by extending the prediction vectors, sharing the ...

Rough Semiring-Valued Fuzzy Sets with Application

open access: yesMathematics, 2022
Many of the new fuzzy structures with complete MV-algebras as value sets, such as hesitant, intuitionistic, neutrosophic, or fuzzy soft sets, can be transformed into one type of fuzzy set with values in special complete algebras, called AMV-algebras. The

BBRefinement: A Universal Scheme to Improve the Precision of Box Object Detectors

open access: yesApplied Sciences, 2022
We present a conceptually simple yet powerful and general scheme for refining the predictions of bounding boxes produced by an arbitrary object detector. Our approach was trained separately on single objects extracted from ground truth labels.

On Unification of Methods in Theories of Fuzzy Sets, Hesitant Fuzzy Set, Fuzzy Soft Sets and Intuitionistic Fuzzy Sets

open access: yesMathematics, 2021
The main goal of this publication is to show that the basic constructions in the theories of fuzzy sets, fuzzy soft sets, fuzzy hesitant sets or intuitionistic fuzzy sets have a common background, based on the theory of monads in categories. It is proven

Reliability and Sensitivity Analysis of Structures Using Adaptive Neuro-Fuzzy Systems [PDF]

open access: yesJournal of Rehabilitation in Civil Engineering, 2020
In this study, Adaptive Neuro-Fuzzy Inference System (ANFIS) and Monte Carlo simulation are applied for reliability analysis of structures. The drawback of Monte Carlo Simulation is the amount of computational efforts.

Observability and Decentralized Control of Fuzzy Discrete Event Systems [PDF]

open access: yes, 2005
Fuzzy discrete event systems as a generalization of (crisp) discrete event systems have been introduced in order that it is possible to effectively represent uncertainty, imprecision, and vagueness arising from the dynamic of systems.

Sustainable Closed-Loop Supply Chain Design Problem: A Hybrid Genetic Algorithm Approach

open access: yesMathematics, 2020
In this paper, we propose a solution to the sustainable closed-loop supply chain (SCLSC) design problem. Three factors (economic, environmental, and social) are considered for the problem and the three following requirements are addressed while ...
