Process Capability Analysis in the Presence of Autocorrelation [PDF]

Journal of Optimization in Industrial Engineering, 2011
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.

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

Weighted Machine Learning for Spatial-Temporal Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Applying machine learning techniques to spatial-temporal data poses the question that how the recorded location and time for training samples should contribute to the training and testing process. The prior knowledge of how spatial-temporal phenomena are

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 ...

New to town: home range size, habitat selection and behavioral adaptations by urban hares

Wildlife Biology, EarlyView.
European hares Lepus europaeus have recently been shown to colonize urban areas in different parts of Europe. This appears to be a novel phenomenon, and little is known about the space use and behavioral adaptations of hares living in urban areas. Here, we describe the first findings concerning home range sizes from GPS‐collared hares (n = 3) in Aarhus

Multioutput least square SVR-based multivariate EWMA control chart: The performance evaluation and application

Cogent Engineering, 2018
Autocorrelation leads to a bias estimator of standard control charts. It is important to develop control chart that allows autocorrelation and to evaluate its performance.

Variation Pattern Recognition of the BIW OCMM Online Measurement Data Based on LSTM NN

IEEE Access, 2019
An accurate recognition of a dimensional variation pattern is very important for producing high-quality body-in-white (BIW). The wide application of optical coordination measurement machines (OCMM) in vehicle factory provided massive online dimensional ...

First insights into the movement patterns of maned wolf with sarcoptic mange

Wildlife Biology, EarlyView.
Understanding how infectious diseases influence wildlife behavior, particularly in habitats undergoing modification, is crucial for predicting disease outbreaks, assessing impacts on population fitness, and mitigating human health risks. Sarcoptic mange can alter wildlife movement and space use, yet its effects on threatened carnivores remain unclear ...

Autocorrelated process monitoring using triggered cuscore charts

, 2002
Some of the most widely-investigated control charting techniques for autocorrelated data are based on time series residuals. If the mean shift in the autocorrelated process is a sudden step shift, the resulting mean shift in the residuals is time varying

Detection‐Dog‐Guided Camera Placement Increases Efficiency of Surveys for Long‐Tailed Weasels (Neogale frenata) 利用探测犬引导布设相机可提升长尾鼬调查效率

Wildlife Letters, EarlyView.
By comparing widespread surveys with randomly placed cameras to a protocol pairing detection dogs with cameras, we found that the detection‐dog‐guided camera survey had approximately 33 times greater detections with fewer camera nights and reduced survey costs. We recommend using detection dogs to identify areas to focus camera trapping. ABSTRACT Multi‐
