Analysis of the stress-strain state of a radially inhomogeneous transversely isotropic sphere with a fixed side surface

open access: yesAdvanced Engineering Research, 2022
Introduction. The paper considers an axisymmetric problem of elasticity theory for a radially inhomogeneous transversally isotopic nonclosed sphere containing none of the 0 and 𝜋 poles.

Effect of Oxide Scale on Hot Dip Zn-Al-Mg Alloy Coating Prepared by Reduction Combined with Induction Heating

open access: yesMetals, 2020
Hot dipping Zn-Al-Mg coatings were prepared by rapid induction heating combined with gas protection. The influence of oxide scale on the structure and surface quality of a hot-dip Zn-6Al-3Mg alloy coating was studied in this paper.

A Quadratic Diophantine Equation Involving Generalized Fibonacci Numbers

open access: yesMathematics, 2020
The sequence of the k-generalized Fibonacci numbers ( F n ( k ) ) n is defined by the recurrence F n ( k ) = ∑ j = 1 k F n − j ( k ) beginning with the k terms 0 , … , 0 , 1 .

Model Order Reduction of Non-Linear Magnetostatic Problems Based on POD and DEI Methods [PDF]

open access: yes, 2014
In the domain of numerical computation, Model Order Reduction approaches are more and more frequently applied in mechanics and have shown their efficiency in terms of reduction of computation time and memory storage requirements. One of these approaches,

Variance reduction methods [PDF]

open access: yesProceedings of the 18th conference on Winter simulation - WSC '86, 1986
A computer simulation model is unusual in that the random error is under the total control of the experimenter. Variance reduction methods aim to take advantage of this to improve experimental accuracy. The fundamental ideas behind the most important of these methods will be described and illustrated with simple examples.

Mulatu Numbers Which Are Concatenation of Two Fibonacci Numbers

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2023
Let (M_k) be the sequence of Mulatu numbers defined by M_0=4, M_1=1, M_k=M_(k-1)+M_(k-2) and (F_k) be the Fibonacci sequence given by the recurrence F_k=F_(k-1)+F_(k-2) with the initial conditions F_0=0, F_1=1 for k≥2.

Survey on attribute and concept reduction methods in formal concept analysis

open access: yes, 2023
Formal concept analysis (FCA) is now widely recognized as a useful approach for extracting, representing, and analyzing knowledge in various domains. The high computational cost of knowledge processing and the difficulty of visualizing the lattice are ...

Curious Generalized Fibonacci Numbers

open access: yesMathematics, 2021
A generalization of the well-known Fibonacci sequence is the k−Fibonacci sequence whose first k terms are 0,…,0,1 and each term afterwards is the sum of the preceding k terms. In this paper, we find all k-Fibonacci numbers that are curious numbers (i.e.,
