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
( 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 ... -
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 ... -
