Common Fixed Point Results of Set Valued Maps for Aφ-Contraction and Generalized ϕ-Type Weak Contraction
( MDPI AG , 2019 , Article)The solutions for many real life problems may be obtained by interpreting the given problem mathematically in the form f(x)=x . One such example is that of the famous Borsuk–Ulam theorem in which, using some fixed point ... -
A semiparametric nonlinear mixed model approach to phase I profile monitoring
( Taylor and Francis Inc. , 2019 , Article)When process data follow a particular curve in quality control, profile monitoring is suitable and appropriate for assessing process stability. Previous research in profile monitoring focusing on nonlinear parametric (P) ... -
Birth and death of spiral waves in a network of Hindmarsh–Rose neurons with exponential magnetic flux and excitable media
( Elsevier Inc. , 2019 , Article)Spiral waves are spatiotemporal patterns, observed in complex networks of biological oscillators such as heart and brain. In this paper, at first a modified Hindmarsh–Rose model with external electromagnetic radiation and ... -
Production of sensitive gas sensors using CuO/SnO2 nanoparticles
( Springer Verlag , 2019 , Article)Metal oxide nanoparticles, such as CuO and SnO2, are outstanding systems for H2S gas sensing in air. In this work, those nanoparticles were deposited with different mixing percentages on substrates to form percolating ... -
Empirical Bayes sequential estimation of a finite population mean
( Taylor and Francis Ltd. , 2019 , Article)In this article, we consider the Bayes and empirical Bayes problem of the current population mean of a finite population when the sample data is available from other similar (m-1) finite populations. We investigate a general ... -
Oscillatory Singular Integral Operators with Hölder Class Kernels
( Birkhauser Boston , 2019 , Article)We establish the boundedness on Lp(Rn) of oscillatory singular integral operators whose kernels are the products of an oscillatory factor with bilinear phase and a Calderón–Zygmund kernel K(x, y) satisfying a Hölder ... -
Invariant characterization of third-order ordinary differential equations u''=f(x,u,u',u) with five-dimensional point symmetry group
( Elsevier B.V. , 2019 , Article)The Cartan equivalence method is applied to provide an invariant characterization of the third-order ordinary differential equation u''=f(x,u,u',u') which admits a five-dimensional point symmetry Lie algebra. The invariant ... -
A novel method to identify initial values of chaotic maps in cybersecurity
( MDPI AG , 2019 , Article)Chaos theory has applications in several disciplines and is focusing on the behavior of dynamical systems that are highly sensitive to initial conditions. Chaotic dynamics are the impromptu behavior displayed by some ... -
Numerical Treatment to a Non-local Parabolic Free Boundary Problem Arising in Financial Bubbles
( Springer International Publishing , 2019 , Article)In this paper, we continue to study a non-local free boundary problem arising in financial bubbles. We focus on the parabolic counterpart of the bubble problem and suggest an iterative algorithm which consists of a sequence ... -
On auxiliary information-based control charts for autocorrelated processes with application in manufacturing industry
( Springer London , 2019 , Article)Multivariate autoregressive (MAR) models are an attractive choice for applications in the processes related to finance, medical, and industry. For the monitoring of such processes, control chart is the most important and ... -
Fixed point results using Ft-contractions in ordered metric spaces having t-property
( MDPI AG , 2019 , Article)In this paper, we prove the existence of fixed points of Ft-contraction mappings in partially ordered metric spaces not necessarily complete. We require that the ordered metric space has the t-property, which is a new ... -
Fabrication and applications of nickel selenide
( Academic Press Inc. , 2019 , Article)This article presents synthetic strategies of different phases and morphologies of nickel selenide in terms of solid state reactions, solvothermal and hydrothermal processes, electrodeposition, precipitation reactions, ... -
Synthesis, characterization and biological applications of selenoureas having ferrocene and substituted benzoyl functionalities
( Elsevier Ltd , 2019 , Article)In this article we have comprehensively reported the synthesis, complete chemical characterization (FTIR, multinuclear NMR, single crystal XRD, CHNS, AAS) and biological applications of seventeen ferrocene incorporated ... -
Construction of S-Box based on chaotic map and algebraic structures
( MDPI AG , 2019 , Article)The Advanced Encryption Standard (AES) is widely used in different kinds of security applications. The substitution box (S-box) is the main component of many modern symmetric encryption ciphers that provides confusion ... -
An Efficient Phase I Analysis of Linear Profiles with Application in Photo-Voltaic System
( Springer Verlag , 2019 , Article)In many manufacturing industries, quality of an item depends on different characteristics and their relationship may be modeled by profiles. For instance, in photo-voltaic (PV) system, output voltage is dependent on the ... -
Characterizing the transitioning epidemiology of herpes simplex virus type 1 in the USA: Model-based predictions
( BioMed Central Ltd. , 2019 , Article)Background: Herpes simplex virus type 1 (HSV-1) is a prevalent lifelong infection that appears to be undergoing an epidemiologic transition in the United States (US). Using an analytical approach, this study aimed to ... -
Validation of the Arabic version of the Social Communication Questionnaire
( SAGE Publications Ltd , 2019 , Article)Validated screening and diagnostic tools for autism spectrum disorder for use in Arabic-speaking individuals are scarce. This study validated the Arabic version of the Social Communication Questionnaire. The total study ... -
Effects of time-lagged meteorological variables on attributable risk of leishmaniasis in central region of Afghanistan
( Elsevier B.V. , 2019 , Article)Background Leishmaniasis remains one of the world's most neglected vector-borne diseases, affecting predominantly poor communities mainly in developing countries. Previous studies have shown that the distribution and ... -
Parameter estimation in a new chaotic memristive system using ions motion optimization
( Springer Verlag , 2019 , Article)In this paper, a new four-dimensional nonlinear oscillator is introduced. This oscillator is memristive and can exhibit chaotic behavior. A complete dynamical analysis is done on each parameter of this system by the help ... -
Extended rectangular b-metric spaces and some fixed point theorems for contractive mappings
