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 ... -
Approximation properties of Bernstein's singular integrals in variable exponent Lebesgue spaces on the real axis
(Ankara Univ, 2022)In generalized Lebesgue spaces Lp(& BULL;) with variable exponent p (& BULL;) defined on the real axis, we obtain several inequalities of approximation by inte-gral functions of finite degree. Approximation properties of ... -
Legendre trajectories of trans-s-manifolds
(Korean Mathematical Soc, 2022)In this paper, we consider Legendre trajectories of trans -S manifolds. We obtain curvature characterizations of these curves and give a classification theorem. We also investigate Legendre curves whose Frenet frame fields ... -

A heat transfer problem with exponential memory and the associated thermal stresses
(Wiley, 2022)In this study, a heat transfer problem defined by the Caputo-Fabrizio derivative, which is known to behave by the exponential decaying law, is addressed in an axially symmetric cylindrical region. Thus, the fundamental ... -
Some fixed-disc results in double controlled quasi-metric type spaces
(MDPI, 2022)In this paper, we introduce new types of general contractions for self mapping on double controlled quasi-metric type spaces, where we prove the existence and uniqueness of fixed disc and circle for such mappings. -
Using optimization method for determining lactic acid bacteria counts in white cheese with different salt concentrations
(Wiley, 2022)Total lactic acid bacteria, Lactococcus spp., yeast, and mold counts in white cheese were determined during 55 days of storage in brine solutions with 4%, 6%, 8%, 10%, 12%, 14%, and 16% (w/v) salt concentrations at 4 degrees ... -
Julia and Mandelbrot Sets of transcendental function via Fibonacci-Mann iteration
(Hindawi Ltd, 2022)In this paper, utilizing the Fibonacci-Mann iteration process, we explore Julia and Mandelbrot sets by establishing the escape criteria of a transcendental function, sin(z(n )) + az + c, n >= 2; here, z is a complex variable, ... -
