On efficient estimation strategies in monitoring of linear profiles
( Springer London , 2018 , Article)A fundamental strategy to diminish variations in manufacturing process urged the practitioners to characterize the quality of a process by a relationship between the response variable and one or more explanatory variables ... -
On existence and uniqueness of best proximity points for proximal β-quasi contractive mappings on metric spaces
( Forum-Editrice Universitaria Udinese SRL , 2021 , Article)This paper focus on the study of the generalization of the best proximity point theorems for non-self contractions. In fact we propose two new theorems on the existence and the uniqueness of best proximity points for ... -
On fixed points of Berinde's contractive mappings in cone metric spaces
( North University of Baia Mare , 2010 , Article)In this paper we establish some common fixed point theorems for two self-mappings satisfying a generalized contractive condition. This result generalizes well known comparable results in the literature. As an application, ... -
On generalized Littlewood–Paley functions
( Springer-Verlag Italia s.r.l. , 2018 , Article)We study the Lp boundedness of certain classes of generalized Littlewood–Paley functions S(f). We obtain Lp estimates of S(f) with sharp range of p and under optimal conditions on ?. By using these estimates along with an ... -
On goodness-of-fit testing for Burr type X distribution under progressively type-II censoring
( Springer , 2022 , Article)In this article, we propose two goodness-of-fit test statistics for the Burr Type X distribution when the available data are subject to progressively Type-II censoring. The proposed test statistics are based on the sample ... -
On improved dispersion control charts under ranked set schemes for normal and non-normal processes
( John Wiley and Sons Ltd , 2019 , Article)In manufacturing industries, control charts are the promising statistical tools used for an efficient monitoring of processes. These charts enhance the product quality by timely signaling for special variations at any stage ... -
On improved monitoring of linear profiles under modified successive sampling
( John Wiley and Sons Ltd , 2019 , Article)Control charts are often used for the monitoring of quality characteristics of interest. There may exist some other characteristics that are associated with the main quality characteristic. A model that quantifies the ... -
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 ...
