Single-step full-state feedback control design for nonlinear hyperbolic PDEs
( Taylor and Francis Ltd. , 2019 , Article)The present work proposes an extension of single-step formulation of full-state feedback control design to the class of distributed parameter system described by nonlinear hyperbolic partial differential equations (PDEs). ... -
Numerical Computing of Preimage Domains for Bounded Multiply Connected Slit Domains
( Springer New York LLC , 2019 , Article)In this paper, for a given bounded multiply connected slit domai, we present an iterative numerical method for computing a conformally equivalent multiply connected domain G bounded by smooth Jordan curves and the conformal ... -
First down converter multilayers integration in an industrial Si solar cell process
( John Wiley and Sons Ltd , 2019 , Article)Down converter SiNx:Yb3+/SiNx:Tb3+ multilayers are deposited by reactive magnetron cosputtering with the objective of optimizing the interaction distance between Tb3+ and Yb3+ ions to favor a better light management in Si ... -
Investigation of Proton Diffusion Coefficient for PbO2 Prepared from Intermediate Oxides
( Pleiades Publishing , 2019 , Article)Lead dioxide was extracted from used batteries, and used to synthesize the following intermediate oxides by heating at different temperatures: Pb12O19, Pb12O17, and Pb3O4. Each of the prepared intermediate oxide was subject ... -
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 ... -
An iterative method for common solution to various problems
( Jangjeon Mathematical Society , 2019 , Article)In this paper, we introduce a new iterative method to find a common solution of a generalized mixed equilibrium problem, a variational inequality problem and a hierarchical fixed point problem for demicontinuous nearly ... -
Collapse dynamics for the discrete nonlinear Schrödinger equation with gain and loss
( Elsevier B.V. , 2019 , Article)We discuss the finite-time collapse, also referred as blow-up, of the solutions of a discrete nonlinear Schrödinger (DNLS) equation incorporating linear and nonlinear gain and loss. Such an extended DNLS system appears in ... -
A semiparametric profile monitoring via residuals
( John Wiley and Sons Ltd , 2019 , Article)Profile monitoring is a vast area of research underneath the statistical process monitoring (SPM). Several methods for univariate and multivariate process control are found in literature to monitor the profile data, including ... -
Validity of the effective potential method to study PT-symmetric field theories
( Elsevier B.V. , 2019 , Article)We calculate the one loop effective potential for the class (-(iϕ)α) of PT-symmetric and non-Hermitian field theories in 0+1 space-time dimensions. To test the method, we showed that for the massless Hermitian ϕ4 theory, ... -
Effective action study of the PT-symmetric (iϕ3)6−ϵ theory and the Yang–Lee edge singularity
( World Scientific Publishing Co. Pte Ltd , 2019 , Article)We use the effective potential method to study the PT-symmetric iϕ3 field theory in 6−ϵ space–time dimensions. For ϵ=0, we obtained the first two energy levels which are real as well as reflecting the stability of the ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
A novel method to identify initial values of chaotic maps in cybersecurity
