A Geostatistical Approach to Estimate High Resolution Nocturnal Bird Migration Densities from a Weather Radar Network

open access: yesRemote Sensing, 2019
Quantifying nocturnal bird migration at high resolution is essential for (1) understanding the phenology of migration and its drivers, (2) identifying critical spatio-temporal protection zones for migratory birds, and (3) assessing the risk of collision ...

Benchmarking Knowledge-assisted Kriging for Automated Spatial Interpolation of Wind Measurements

open access: yes
- We have benchmarked a novel knowledge-assisted kriging algorithm that allows regions of spatial cohesion to be specified and variograms calculated for each region.

Kriging-based Finite Element Method for Analyses of Reissner-Mindlin Plates [PDF]

open access: yes, 2006
A class of finite element method using kriging shape functions is developed to analyze Reissner-Mindlin plates. The shape functions are constructed using kriging interpolation (KI) over a set of nodes encompassing a number of layers of elements.

Diagnostics of an Aircraft Engine Pumping Unit Using a Hybrid Approach based-on Surrogate Modeling [PDF]

open access: yes, 2013
This document introduces a hybrid approach for fault detection and identification of an aircraft engine pumping unit. It is based on the complementarity between a model-based approach accounting for uncertainties aimed at quantifying the degradation ...

Computationally Efficient Ranking of Sampling Locations by Redundancy in Groundwater Monitoring Networks

open access: yesGroundwater Monitoring &Remediation, EarlyView.
Abstract The long‐term and frequent sampling of groundwater monitoring networks is common practice for monitoring the concentrations of constituents of potential concern (CoPC) over space and time. Sampling can be a costly and time‐intensive process that also incurs health and safety risks. A redundancy‐based ranking of candidate sampling locations can

On Spatial Point Processes With Composition‐Valued Marks

open access: yesInternational Statistical Review, EarlyView.
Summary Methods for marked spatial point processes with scalar marks have seen extensive development in recent years. While the impressive progress in data collection and storage capacities has yielded an immense increase in spatial point process data with highly challenging non‐scalar marks, methods for their analysis are not equally well developed ...

Kriging-Based Design of Experiments for Multi-Source Exposure–Response Studies in Nanotoxicology

open access: yes, 2017
For the sustainable development of nanomaterials (NMs), it is critical to assess the toxic potency of NMs. One of the major challenges with toxicology studies of NMs, compared to traditional materials or chemicals, lies in the large NM variety (or source

A Non‐Parametric Framework for Correlation Functions on Product Metric Spaces

open access: yesInternational Statistical Review, EarlyView.
Summary We propose a non‐parametric framework for analysing data defined over products of metric spaces, a versatile class encountered in various fields. This framework accommodates non‐stationarity and seasonality and is applicable to both local and global domains, such as the Earth's surface, as well as domains evolving over linear time or time ...
