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 ... -
Fast and Accurate Computation of the Logarithmic Capacity of Compact Sets
( Springer Berlin Heidelberg , 2017 , Article)We present a numerical method for computing the logarithmic capacity of compact subsets of C, which are bounded by Jordan curves and have finitely connected complement. The subsets may have several components and need not ... -
Optimization design of the CUSUM and EWMA charts for autocorrelated processes
( John Wiley and Sons Ltd , 2017 , Article)The traditional control charts produce frequent false alarm signals in the presence of autocorrelation. The implementation of the modified chart scheme is a way of handling the problem of autocorrelation in control charts. ... -
Poisson progressive mean control chart
( John Wiley and Sons Ltd , 2017 , Article)In real life applications, many process-monitoring problems in statistical process control are based on attribute data resulting from quality characteristics that cannot be measured on numerical or quantitative scales. For ... -
Chimera state in a two-dimensional network of coupled genetic oscillators
( Institute of Physics Publishing , 2019 , Article)Due to the interaction of the cells, cellular communications are carried out with emergent collective behaviors, such as synchronization. In this paper, a network of coupled genetic oscillators is studied by considering a ... -
An enhanced nonparametric EWMA sign control chart using sequential mechanism
( Public Library of Science , 2019 , Article)Control charts play a significant role to monitor the performance of a process. Nonparametric control charts are helpful when the probability model of the process output is not known. In such cases, the sampling mechanism ... -
Endpoint Estimates for Oscillatory Singular Integrals with H�lder Class Kernels
( Hindawi Limited , 2019 , Article)We prove the uniform L1?L1,? and HE 1?L1 boundedness of oscillatory singular integral operators whose kernels are the products of an oscillatory factor with bilinear phase and a Calder�n-Zygmund kernel K(x,y) satisfying a ... -
Efficient cv control charts based on ranked set sampling
( Institute of Electrical and Electronics Engineers Inc. , 2019 , Article)Monitoring process variability is essential for establishing efficient process-control schemes. In practice, when the mean levels of a parameter are constant, and the process variance (or standard deviation) is independent ... -
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 ... -
Edge maximal non-bipartite Hamiltonian graphs without theta graphs of order 7
( Forum-Editrice Universitaria Udinese SRL , 2019 , Article)For a set of graphs F, let H(n; F) denote the class of non-bipartite Hamiltonian graphs on n vertices that does not contain any graph of F as a subgraph and h(n; F) = max{E(G): G ? H(n; F)} where E(G) is the number of edges ... -
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 ... -
Fabrication and characterization of poly(vinyl alcohol)-Glycerol-Spinel ferrites flexible membranes
( John Wiley and Sons Inc. , 2019 , Article)Polymer membranes of ferrites nanoparticles, glycerol, and poly(vinyl alcohol) (PVA) were fabricated using a solution casting method. Spinel ferrites nanoparticles, CuFe2O4 or ZnFe2O4, and glycerol were used as dopants to ... -
