The online measurement of coal ash has overcome the shortcomings chemical tests. However, there could be large fluctuations and errors in results monitors because transient change quality resulting from different geological conditions mining process. In this study, to resolve problems dual-energy γ-ray monitor Linhuan Coal Preparation Plant, we investigated internal factors, such as composition...

Image acquisition systems invariably introduce blur, which necessitates the use of deblurring algorithms for image restoration. Restoration techniques involving regularization require appropriate selection of the regularization parameter that controls the quality of the restored result. We focus on the problem of automatic adjustment of this parameter for nonlinear image restoration using analy...

Heart rate variability (HRV) analysis is a non-invasive tool for assessing cardiac health. Entropy measures quantify the chaotic properties of HRV, but they are sensitive to the choice of their required parameters. Previous studies therefore have performed parameter optimization, targeting solely their particular patient cohort. In contrast, this work aimed to challenge entropy measures with re...

Approximate Bayesian Computation is a family of likelihood-free inference techniques that are tailored to models defined in terms of a stochastic generating mechanism. In a nutshell, Approximate Bayesian Computation proceeds by computing summary statistics from the data and giving more weight to the values of the parameters for which the simulated summary statistics resemble the observed ones. ...

Several optimizations to the Time Warp synchronization protocol for parallel discrete event simulation have been proposed and studied. Many of these optimizations have included some form of dynamic adjustment (or control) of the operating parametersof the simulation (e.g., checkpoint interval, cancellation strategy). Traditionally dynamic parameter adjustment has been performed at the simulatio...

A 23-year-old woman without history of antecedent vocal, respiratory, or sleep disorders received vagus nerve stimulation (VNS) therapy for refractory partial epilepsy and developed sleep-related stridor during the course of parameter titration. Reduction of VNS current during polysomnography completely eliminated stridor. We conclude that VNS may cause sleep-related stridor in rare cases, expa...

Motivation is assumed to influence behaviors via perceived agency over goal pursuits, but empirical research integrating motivation and action-control processes in social development is close to nonexistent. We applied this perspective to the study of early adolescent friendships by examining motivation for and perceived control (ability and effort) over establishing and maintaining friendships...
