Comparison of Process Capability Indices under Autocorrelated Data Comparación de índices de capacidad de procesos con datos autocorrelacionados

Revista Colombiana de Estadística, 2007
The process capability indices provide a measure of how a process fits within the specification limits. In calculating indices is usual to assume that the process data are independent.

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.

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 ...

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.

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.

Monitoring the effects of ovariectomy on seasonal movement behavior in suburban female white‐tailed deer using internet of things‐enabled devices

Wildlife Biology, EarlyView.
Abundant deer populations often cause conflicts in suburban communities, yet traditional population reduction methods, such as controlled hunting, can be challenging to implement. Fertility control, specifically through ovariectomy, can limit reproduction and reduce populations in certain settings, but its effect on movement behavior remains poorly ...

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

A dog makes a difference: exploration of potential biases in moose‐hunting associated citizen science

Wildlife Biology, EarlyView.
The collection of citizen data is often employed to generate insights regarding species distribution, population sizes, and population structure; however, biases inherent in citizen science are seldom addressed. In this study, we examined the factors influencing hunters' observations of moose, Alces alces, during the moose hunting season in Finland. By
