Anomaly detection methods for unmanned underwater vehicle performance data
… focus on two anomaly detection techniques: (1) Kernel Density Estimation (KDE) Anomaly Detection and (2) Local Outlier Factor. Results are presented for selected UUV systems and data features, and initial findings provide insight into the effectiveness of these algorithms. Lastly, we explore …

Nonlinear dynamic process monitoring using kernel methods
The application of kernel methods in process monitoring is well established. How- ever, there is need to extend existing techniques using novel implementation strate- gies in order to improve process monitoring performance. For example, process monitoring using kernel principal component analysis …

Graphical tools for the examination of high-dimensional functions obtained as the result of Bayesian analysis
… – especially Projection Pursuit methods – and Kernel Density Estimation (KDE). During the course of this work acceptable prior technology was found for MCMC and, once the decision for it had been made, Projection Pursuit. However, the current state of KDE gave rise to several objections. Not …

Zero-Waste Planning at Higher Education Institutions: A Case Study of Western Kentucky University
… to each building, were analyzed with the Kernel Density Estimation (KDE) method. Buildings that were high-volume waste generators included buildings with food facilities, suggesting close review of policies related to food practices is essential for developing WM schemes. Furthermore, …

An Assessment of Habitat Suitability for Pronghorn Populations of the Central Valley Region of California
… scrub, crops, and bare areas), slope, and road density. Vegetation and road density variables were treated categorically and slope as a continuous variable. Kernel density estimation (KDE) was used to estimate utilization distributions and home ranges (Fieberg 2007). An 80% isopleth was used to …

Cognitive Radar Detection in Nonstationary Environments and Target Tracking
… of clutter distribution by using kernel density estimation (KDE) methods and similarity measures (iii) adaptive target detection by automatically modifying the likelihood-ratio test and the corresponding detection threshold. We also conduct extensive numerical experiments to show …

Anomaly Detection for Smart Infrastructure: An Unsupervised Approach for Time Series Comparison
… Support Vector Machine (OCSVM) coupled with a Kernel Density Estimation (KDE) technique. The average Recall and Precision achieved on the same case study through this frame work was 74% and 57%. In comparison to the first, the second framework does not perform as well. There will be future …

Plasma turbulence in the equatorial electrojet observations, theories, models, and simulations
… studied for more than seven decades. The sharp density-gradient and large conductivity give rise to gradient-drift and Farley-Buneman instabilities, respectively, of different scale-lengths. A new 2-D fluid model is derived by modifying the standard two-stream fluid model with the ion viscosity …

Elephant space use in relation to ephemeral surface water availability in the eastern Okavango Panhandle, Botswana
… and Home Range (HR) sizes estimated using Kernel Density Estimation (KDE). The relative importance/probability of environmental variables in determining elephants' movement based on the Utilization Distribution (UD) were computed using Generalized Linear Mixed Models (GLMMs). I utilized a …

Anthropogenic effects on site use and temporal patterns of terrestrial mammals in Harenna Forest, Ethiopia
There has been little research comprehensively documenting wildlife species in Harenna Forest within the Bale Mountains National Park of Ethiopia. This area is one of the few remaining afro-alpine biodiversity hotspots and is home to numerous endemic plants and animals and offers socio-economic …

The void fraction in headers of microchannel heat exchangers
… the time plot of normalized capacitive signals, kernel density estimation (KDE), power spectral density (PSD), and visualization results from a high-speed camera. Sensors with the same design can and will be utilized directly to measure void fraction and characterize flow regimes for similar test …
