This paper examines the exponentially weighted moving average (EWMA) chart with estimated process parameters. As the run length distribution is skewed when the process is in-control or slightly out-of-control, the average run length (ARL) provides less meaningful interpretation of a chart's ...
In the present article, we study the effect of estimating the vector of means and variance-covariance matrix in the performance of the multivariate exponentially weighted moving average (MEWMA) control chart. We show through simulation that the performance of the MEWMA control chart is affected when...
(2021). A great deal of process monitoring literature focuses on the exponentially weighted moving average (EWMA) and cumulative sum (CUSUM) control charts (see, for example, Jones et al., 2004, Castagliola et al., 2016). These control charts are generally favored over the traditional ...
We also assessed the change in forest height in the vicinity of degraded forests (forest-degraded forest edge effects). We observed that canopy heights in undisturbed forests near logged or burned forests (that is, within a 120 m radius) were on average significantly lower than in intact for...
For the channel attention module, a similar self-attention mechanism is introduced to capture the channel dependency between any two channel maps, and the feature map of each channel is updated using the matrix multiplication and weighted sum of all channel feature maps. Finally, the outputs of ...
In what sense are the squares "least"? R2 R2 Coefficient of Determination: The coefficient of determination shows the relationship between explanatory and explained variables. This is often defined as "R-Squared". The higher the R-squared value is th...
We find Huber-weighted rms misfits of 0.36, 0.36 and 0.40 nT for along-track differences of the radial, north–south and east–west vector field components from CHAMP. The along-track differences of Swarm vector data thus have generally smaller residuals than similar differences constructed with ...
(Bruker, Germany). The head of the bat was placed in a head holder to minimize movement and the body was laid on a water-based heated animal bed. Temperature and respiration were recorded using monitoring devices. A standard T1-weighted FLASH3D sequence was used to evaluate and identify ...
