Phase-II Monitoring of AR (1) Autocorrelated Polynomial Profiles [PDF]

Journal of Optimization in Industrial Engineering, 2014
In some statistical process control applications, quality of a process or product can be characterized by a relationship between a response and one or more independent variables, which is typically referred to a profile.

NowPrecip 2: Precipitation nowcasting in the complex terrain of Switzerland. Part I: Methods

Quarterly Journal of the Royal Meteorological Society, EarlyView.
In this work we present the methods of the areal precipitation nowcasting system NowPrecip version 2. In this version a new methodology is introduced, which, although it shares philosophy and techniques with the original methodology of NowPrecip version 1, can be considered as distinct from that.

Process Capability Analysis in the Presence of Autocorrelation [PDF]

Journal of Optimization in Industrial Engineering, 2013
The classical method of process capability analysis necessarily assumes that collected data are independent; nonetheless, some processes such as biological and chemical processes are autocorrelated and violate the independency assumption.

Integral equation solutions for the average run length for monitoring shifts in the mean of a generalized seasonal ARFIMAX(P, D, Q, r)s process running on a CUSUM control chart.

PLoS ONE, 2022
The CUSUM control chart is suitable for detecting small to moderate parameter shifts for processes involving autocorrelated data. The average run length (ARL) can be used to assess the ability of a CUSUM control chart to detect changes in a long-memory ...

Autocorrelated multivariate process control: a geometric brownian motion approach

, 2013
In real life we always come across autocorrelated multivariate process where the present process is related to the previous process. This type of process can be modeled using the traditional multivariate time series models and then the process control ...

A CNN Approach for Simultaneous Spatiotemporal Fault Interpretation

Quality and Reliability Engineering International, EarlyView.
ABSTRACT Convolutional Neural Networks (CNNs) have emerged as one of the most effective tools for image analysis. In this study, we propose a custom‐designed CNN architecture to construct a process control scheme based on image data. The product image is partitioned into equal‐sized grids, each comprising three channels: (i) reference image, (ii ...

Women's Empowerment, Governance, and the Economics of Clean Cooking Transitions in Africa

Sustainable Development, EarlyView.
ABSTRACT Over the past few decades, the global economy, particularly in developing nations, has persistently grappled with rising dependence on conventional energy resources, thus rendering the realization of Sustainable Development Goals 5 and 7 (SDGs 5 and 7) an elusive aspiration for the international community.

A two-sided Bernoulli-based CUSUM control chart with autocorrelated observations

Journal of Industrial Engineering International, 2018
Usually, in monitoring a proportion p, the binary observations are considered independent; however, in many real cases, there is a continuous stream of autocorrelated binary observations in which a two-state Markov chain model is applied with first-order
