Data-Driven Surrogate-Assisted Optimization of Metamaterial-Based Filtenna Using Deep Learning
(MDPI, 2023)In this work, a computationally efficient method based on data-driven surrogate models is proposed for the design optimization procedure of a Frequency Selective Surface (FSS)-based filtering antenna (Filtenna). A Filtenna ... -
Approximation by Generalized Integral Favard-Szasz Type Operators Involving Sheffer Polynomials

Magnetic Transitions in Two Novel Mixed-Valence Iron(Ii)–Iron(Iii) Metal Formate Frameworks : Two Sublattice Model
(Elsevier B.V., 2022)We study the two-sublattice model in the mean field theory by expanding the Gibbs free energy in terms of the magnetizations M1 (Mup) and M2 (Mdown) with the quadratic coupling M12M22 (quadrupolar interactions) for the ... -
Calculation of the Liquid-Solid Phase Diagram and the Thermodynamic Quantities of the Binary System of Tetradecane and Hexadecane Using the Mean Field Theory
(Springer/Plenum Publishers, 2021)The T - x phase diagram of a binary system of tetradecane + hexadecane is calculated using the Landau phenomenological model. Expressions derived for the phase lines are fitted to experimental data from the literature and ... -
Bilinear Multipliers of Small Lebesgue Spaces
(Scientific Technical Research Council Turkey, 2021)Let G be a compact abelian metric group with Haar measure lambda and (G) over cap its dual with Haar measure mu. Assume that 1 < p(i) < infinity, p(i)' = p(i)/p(i)-1, (i = 1, 2, 3) and theta >= 0. Let L-(pi' ,L-theta (G), ... -
On a New Approach by Modified (P; Q)-Szasz-Mirakyan Operators
(Etamaths Publ., 2021)In this paper, we introduce a new type of (p; q) exponential function with some properties and a modified (p; q)-Szasz-Mirakyan operators by virtue of this function by investigating approximation properties. We obtain ... -
Wavelet-ANFIS hybrid model for MODIS NDVI prediction
(Spie-Soc Photo-Optical Instrumentation Engineers, 2021)Urbanization at the expense of the natural environment has been increasing in Turkey in recent years. The toll it takes on the ecosystem has an adverse impact on local weather systems and natural resources. These rapid ... -
Best proximity points of admissible almost generalized weakly contractive mappings with rational expressions on b-metric spaces
(Journal Mathematics & Computer Science-JMCS, 2021)The aim of this paper is to introduce almost generalized proximal (alpha - psi - phi - theta)-weakly contractive mappings with rational expressions and prove the best proximity point theorems for such mappings. The main ... -
On the Grand Wiener Amalgam Spaces
(Rocky Mt Math Consortium, 2020)We define the grand Wiener amalgam space by using the classical Wiener amalgam space and the generalized grand Lebesgue space. Moreover we study the inclusions between these spaces and some applications. Finally we prove ... -
Thermodynamic study on the magnetic transition and structural phase transition in [(CH3)(2)NH2][Na0.5Fe0.5(HCOO)(3)] by using the Landau phenomenological model
(Amer Inst. Physics, 2020)In this study, we apply the Landau phenomenological model to describe magnetic transition and structural phase transition in a metal formate framework (MOF) of the ferromagnetic [(CH3)(2)NH2][Na0:5Fe0:5(HCOO)(3)], namely, ... -
Calculation of Magnetization and Magnetic Susceptibility Close to Magnetic Phase Transitions in (CH3)(2)(NH2FeNiII)-Ni-III(HCOO)(6) and (CH3)(2)(NH2FeCuII)-Cu-III(HCOO)(6)
(Springer/Plenum Publishers, 2020)We study the temperature and magnetic field dependence of the magnetization (M) and the inverse susceptibility (chi(-1)) in the metal-organic frameworks, in particular, for (CH3)(2)(NH2FeNiII)-Ni-III(HCOO)(6) (DMFeNi) and ... -
W(L-p, L-q) boundedness of localization operators associated with the Stockwell transform

A dynamic inverse distance weighting-based local face descriptor
(Springer, 2020)This paper proposes a novel high-performance dynamic inverse distance weighting based local descriptor (DIDWLD) for facial recognition. Studies proposed thus far have focused on finding local descriptors that can represent ... -
Application of artificial intelligence neural network modeling to predict the generation of domestic, commercial and construction wastes
(Sage, 2020)Reliable prediction of municipal solid waste (MSW) generation rates is a significant element of planning and implementation of sustainable solid waste management strategies. In this study, the multi-layer perceptron ... -
A class of second order nondifferentiable symmetric duality relations under generalized assumptions
(Journal Mathematics & Computer Science-JMCS, 2020)In this article, a pair of second-order nondifferentiable symmetric dual model in optimization problem is formulated over arbitrary cones. For a differentiable function, we consider the definition of strongly K-pseudobonvexity ... -
Maximal normal subgroups of the automorphism groups of free nilpotent groups
(Kossuth Lajos Tudomanyegyetem, 2020)We prove that the subgroup of all IA-automorphisms of the automorphism group Aut(N) of a free nilpotent group N of infinite rank is normality-small. As a consequence, every maximal normal subgroup of the group Aut(N) is a ... -
Variation of the raman frequency of a soft mode with the pressure (20 oc) for the phase transitions in NH4F
(2016)The Raman frequency of a soft mode (238 cm-1) is analyzed as a function of pressure at 20 oC for NH4F using the experimental data from the literature. This analysis is performed for the pressure dependence of the Raman ... -
Pippard relations for cubic gauche nitrogen
(2016)The Pippard relations (CP vs. ?P and ?P vs. ?T) are examined at various temperatures up to 1200 K at zero pressure (P = 0) for the cubic gauche nitrogen. The specific heat (CP) is related to the thermal expansion (?P) and ... -
