On Indefinite Quadratic Optimization over the Intersection of Balls and Linear Constraints
( Springer , 2022 , Article)In this paper, we study the minimization of an indefinite quadratic function over theintersection of balls and linear inequality constraints (QOBL). Using the hyperplanesinduced by the intersection of each pair of balls, ... -
On Mixed Equilibrium Problems in Hadamard Spaces
( Hindawi Limited , 2019 , Article)The main purpose of this paper is to study mixed equilibrium problems in Hadamard spaces. First, we establish the existence of solution of the mixed equilibrium problem and the unique existence of the resolvent operator ... -
On Model Selection for Autocorrelated Processes in Statistical Process Control
( John Wiley and Sons Ltd , 2017 , Article)Using traditional control charts to monitor autocorrelated processes is not beneficial, because it will lead us to misleading detections in the processes. One of the methods used to deal with the control charts for ... -
On multistage ranked set sampling for distribution and median estimation
( Elsevier B.V. , 2007 , Article)A variation of ranked set sampling (RSS), multistage RSS (MSRSS), is investigated for the estimation of the distribution function and some of its quantiles, in particular the median. It is shown that this method is ... -
On Phase-I monitoring of process location parameter with auxiliary information-based median control charts
( MDPI AG , 2020 , Article)A control chart is often used to monitor the industrial or services processes to improve the quality of the products. Mostly, the monitoring of location parameters, both in Phase I and Phase II, is done using a mean control ... -
On reality and asymptotics of zeros of q-Hankel transforms
( Elsevier Inc. , 2008 , Article)We give sufficient conditions which guarantee that the finite q-Hankel transforms have only real zeros which satisfy some asymptotic relations. The study is carried out using two different techniques. The first is by a use ... -
On rough maximal operators and Marcinkiewicz integrals along submanifolds
(2009 , Article)We investigate the LP boundedness for a class of parametric Marcinkiewicz integral operators associated to submanifolds and a class of related maximal operators under the L(log L)α(Sn-1) condition on the kernel functions. ... -
On some statistical approximation by (p, q)-Bleimann, Butzer and Hahn Operators
( MDPIAG , 2018 , Article)In this article, we propose a different generalization of (p, q)-BBH operators and carry statistical approximation properties of the introduced operators towards a function which has to be approximated where (p, q)-integers ... -
On stability of equilibrium points in nonlinear fractional differential equations and fractional Hamiltonian systems
( Wiley Periodicals, Inc.� , 2014 , Article)In this article, a brief stability analysis of equilibrium points in nonlinear fractional order dynamical systems is given. Then, based on the first integral concept, a definition of planar Hamiltonian systems with fractional ... -
On strongly generalized convex stochastic processes
( Taylor and Francis Ltd. , 2022 , Article)In this paper, we introduce the notion of strongly generalized convex functions which is called as strongly η-convex stochastic processes. We prove the Hermite-Hadamard, Ostrowski type inequality, and obtain some important ... -
On the 'independence of trials-assumption' in geometric distribution
( Taylor & Francis, Ltd , 2008 , Article)In this note, it is shown through an example that the assumption of the independence of Bernoulli trials in the geometric experiment may unexpectedly not be satisfied. The example can serve as a suitable and useful classroom ... -
On the basis number of the wreath product of ladders
( Charles Babbage Research Centre , 2016 , Article)The basis number of a graph G is defined to be the least non negative integer d such that there is a basis B of the cycle space of G such that each edge of G is contained in at most d members of B. In this paper, we determine ... -
On the boundedness of a class of rough maximal operators on product spaces
(2011 , Article)In this paper, we study the Lp boundedness of a class of maximal operators T (γ) {Ωj} and a related class of rough singular integrals on product spaces. We obtain appropriate Lp estimates for such maximal operators and ... -
On the boundedness of rough oscillatory singular integrals on Triebel-Lizorkin spaces
( springer link , 2011 , Article)We obtain appropriate sharp bounds on Triebel-Lizorkin spaces for rough oscillatory integrals with polynomial phase. By using these bounds and using an extrapolation argument we obtain some new and previously known results ... -
On the estimation of reliabilty function in a Weibull lifetime distribution
( Taylor & Francis , 2008 , Article)The estimation of the reliability function of the Weibull lifetime model is considered in the presence of uncertain prior information (not in the form of prior distribution) on the parameter of interest. This information ... -
On the existence of positive solutions for generalized fractional boundary value problems
( Springer , 2019 , Article)The existence of positive solutions is established for boundary value problems defined within generalized Riemann–Liouville and Caputo fractional operators. Our approach is based on utilizing the technique of fixed point ... -
On the Investigation of Monthly River Flow Generation Complexity Using the Applicability of Machine Learning Models
( Hindawi Limited , 2021 , Article)Streamflow is associated with several sources on nonstationaries and hence developing machine learning (ML) models is always the motive to provide a reliable methodology to understand the actual mechanism of streamflow. ... -
On the Lp boundedness of rough parametric Marcinkiewicz functions
( Victoria University , 2007 , Article)In this paper, we study the Lp boundedness of a class of parametric Marcinkiewicz integral operators with rough kernels in L(log + L)(Sn-1). Our result in this paper solves an open problem left by the authors of ([6]). -

On the nonexistence of degenerate phase-shift discrete solitons in a dNLS nonlocal lattice
( Elsevier B.V. , 2018 , Article)We consider a one-dimensional discrete nonlinear Schrdinger (dNLS) model featuring interactions beyond nearest neighbors. We are interested in the existence (or nonexistence) of phase-shift discrete solitons, which correspond ...
