Determination of heterogeneity for manganese dendrites using lacunarity analysis
(2022)The surface patterns of natural and experimental deposits are important as they result from the internal microstructure. For this purpose, lacunarity analysis is applied to determine the heterogeneous nature of deposit ... -
Examining of a tumor system with Caputo derivative
(2023)Cancer is a disease that many people are exposed to, which results in the recovery of some and the death of others. For this reason, A system reflecting the relationship between immune system and tumor growth in this study ... -
Modelling influenza a disease dynamics under Caputo-Fabrizio fractional derivative with distinct contact rates
(2023)The objective of this manuscript is to present a novel approach to modeling influenza A disease dynamics by incorporating the Caputo-Fabrizio (CF) fractional derivative operator into the model. Particularly distinct contact ... -
Conformable Flett’s theorem and Sahoo and Riedel theorem
(2023)Since fractional analysis has attracted considerable interest by virtue of their ability to model complex phenomena, it is crucial to investigate properties of fractional derivatives. In this research, accordingly, we first ... -
Sb-metrik uzaylarda bazı sabit eğriler üzerine
(2023)Bu çalışmada, Sb - metrik uzaylarda sabit figüre problemleri için yeni çözümlerden bahsedilecektir. Özellikle, Cassini Eğrisi ve Apoollonius çemberi üzerinde durulacaktır. Bunun için ilk olarak Moradi tipinde Cu1u2-Sb ... -
A new characterization of tzitzeica curves in euclidean 4-space
(2023)In this study, we are interested in Tzitzeica curves (Tz-curves) in Euclidean 4 -space. Tz-curve condition for Euclidean 4 -space are determined as three types for three hyperplanes and some examples are given. -
Two-dimensional Cattaneo-Hristov heat diffusion in the half-plane
(2023)In this paper, Cattaneo-Hristov heat diffusion is discussed in the half plane for the first time, and solved under two different boundary conditions. For the solution purpose, the Laplace, and the sine- and exponential- ... -
Exponential approximation in variable exponent Lebesgue spaces on the real line
(Tuncer Acar, 2022)Present work contains a method to obtain Jackson and Stechkin type inequalities of approximation by integral functions of finite degree (IFFD) in some variable exponent Lebesgue space of real functions defined on R := ... -
New fixed-disc results via bilateral type contractions on s-metric spaces
(Balıkesir Üniversitesi, 2022)There are some examples of self-mappings which does not satisfy the Banach contractive condition and have a unique fixed point or more than one fixed point. In this case, metric fixed-point theory has been extensively ... -
Mathematical analysis and simulation of a giving up smoking model within the scope of non-singular derivative
(Inst Mathematics & Mechanics, 2022)Smoking has caused the illness and death of many people around the world for a long time. Therefore, many researchers have investigated many methods to quit smoking and reduce its use. In this paper, a smoking model with ... -
Approximation by de la valleee poussin means in weighted generalized grand smirnov classes
(Turkic World Mathematical Soc, 2022)Let G be a simple connected domain on complex plane such that Gamma := partial derivative G where Gamma is a Carleson curve. In this work, we investigate the rate of approximation by De La Vallee Poussin mean constructed ... -
Simultaneous-Maximal approximation by Taylor partial sums
(Inst Mathematics & Mechanics, 2022)In this work simultaneous-maximal approximation proper-ties of Taylor partial sums in the canonical disks are investigated. -
A new study on the fixed point sets of proinov-type contractions via rational forms
(MDPI, 2022)In this paper, we presented some new weaker conditions on the Proinov-type contractions which guarantees that a self-mapping T has a unique fixed point in terms of rational forms. Our main results improved the conclusions ... -
On the covering radii of a class of binary primitive cyclic codes
(Hacettepe Univ, 2022)In 2019, Kavut and Tutdere proved that the covering radii of a class of primitive binary cyclic codes with minimum distance greater than or equal to r + 2 is r, where r is an odd integer, under some assumptions. We here ... -
A new generalization of Rhoades' condition
(Ramazan Yaman, 2022)In this paper, our aim is to obtain a new generalization of the well-known Rhoades' contractive condition. To do this, we introduce the notion of an S-normed space. We extend the Rhoades' contractive condition to S-normed ... -
On discontinuity problem with an application to threshold activation function
(Univ Nis, 2022)In this paper, some discontinuity results are obtained using the number M-C(t, t*) defined as M-C(t, t*) = max {(d(t, t*), ad(t, Tt) + (1-a)d(t*, St*))((1 -a)d(t, Tt) + ad(t*, St*),b/2 [d(t, St*) + d(t*, Tt))}, at ... -
Revisiting some popular contractive conditions for the fixed-circle problem
(Tsing Hua Univ, 2022)The main aim of this paper is to present some fixed-disc theorems as new solutions to the fixed-circle problem. For this purpose, we define the notions of Moradi type a(0)-contraction, Geraghty type a(0)- contraction, ... -
Uncertainty-based Gompertz growth model for tumor population and its numerical analysis
(Ramazan Yaman, 2022)For treating cancer, tumor growth models have shown to be a valuable re-source, whether they are used to develop therapeutic methods paired with process control or to simulate and evaluate treatment processes. In addition, ... -
Dynamic analysis of a fractional svir system modeling an infectious disease
(Univ Nis, 2022)Infectious diseases that spread by microorganisms, viruses and bacteria that can be transmitted very quickly from person to person and have negative effect on public health should be treated as soon as possible. In order ... -
Efficient solution of fractional-order SIR epidemic model of childhood diseases with optimal homotopy asymptotic method
(IEEE-Inst Electrical Electronics Engineers Inc, 2022)In providing an accurate approximate analytical solution to the non-linear system of fractional-order susceptible-infected-recovered epidemic model (FOSIREM) of childhood disease has been a challenge, because no norm to ...
