Stress State of Elastic Thick-Walled Ring With Self-Balanced Pressures Distributed on Its Internal and External Borders

open access: yesVestnik Volgogradskogo Gosudarstvennogo Universiteta. Serija 1. Mathematica. Physica, 2015
For the first time with the help of the theory of analytic functions and Kolosov-Muskhelishvili formulas the problem of the two-dimensional theory of elasticity for a thickwalled ring with the uneven pressures, acting on its borders, was solved.

Analyzing Self-Explanations in Mathematics: Gestures and Written Notes Do Matter

open access: yesFrontiers in Psychology, 2020
When learners self-explain, they try to make sense of new information. Although research has shown that bodily actions and written notes are an important part of learning, previous analyses of self-explanations rarely take into account written and non ...

Complex Color Space Segmentation to Classify Objects in Urban Environments

open access: yesMathematics, 2022
Color image segmentation divides the image into areas that represent different objects and focus points. One of the biggest problems in color image segmentation is the lack of homogeneity in the color of real urban images, which generates areas of over ...

Applications of neutrosophic complex numbers in triangles [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
It may be difficult for researchers to memorize or remember the trigonometric ratios of any neutrosophic angle, and this is what prompted us to activate the role of the neutrosophic complex numbers for that.

A Note on Generalized Hybrid Tribonacci Numbers

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2020
In this paper, we introduce the generalized hybrid Tribonacci numbers. These numbers can be considered as a generalization of the generalized complex Tribonacci, generalized hyperbolic Tribonacci and generalized dual Tribonacci numbers.

Drawing with Complex Numbers

open access: yes, 2000
It is not commonly realized that the algebra of complex numbers can be used in an elegant way to represent the images of ordinary 3-dimensional figures, orthographically projected to the plane. We describe these ideas here, both using simple geometry and

Developing complex analysis textbook to enhance students’ critical thinking

open access: yesJournal of Research and Advances in Mathematics Education, 2020
Critical thinking skill was needed since problems in daily life required a solution. To solve the problems, the students collect the data as a consideration in making the right decision. Moreover, the students also need good critical thinking skills.

On Harmonic Complex Balancing Numbers

open access: yesMathematics, 2022
In the present work, we define harmonic complex balancing numbers by considering well-known balancing numbers and inspiring harmonic numbers. Mainly, we investigate some of their basic characteristic properties such as the Binet formula and Cassini ...

Complex Numbers, Quantum Mechanics and the Beginning of Time

open access: yes, 1993
A basic problem in quantizing a field in curved space is the decomposition of the classical modes in positive and negative frequency. The decomposition is equivalent to a choice of a complex structure in the space of classical solutions.
