Semivariogram analysis of bone images implemented on FPGA architectures [PDF]

Journal of Real-Time Image Processing, 2016
Osteoporotic fractures are a major concern for the healthcare of elderly and female populations. Early diagnosis of patients with a high risk of osteoporotic fractures can be enhanced by introducing second-order statistical analysis of bone image data using techniques such as variogram analysis.

A Step Toward Rainfall Erosivity Mapping Over Türkiye Using Kriging With External Drift

Hydrological Processes, Volume 40, Issue 3, March 2026.
This study maps rainfall erosivity (R factor) across Türkiye by integrating station‐based observations with satellite‐based precipitation data. The Modified Fournier Index (MFI) derived from CHIRPS was first validated against ground measurements and subsequently incorporated as auxiliary information within a kriging with external drift (KED) framework.

Study of the spatial variability of moisture and compaction in soils with different plant covers

Agronomía Colombiana, 2016
Soil is a dynamic system, with physical, chemical and biological properties that have high spatial variability, making necessary to use innovative methodologies to study this variability.

Quantifying Gas and Thermal Energy Emissions in an Active Geothermal Area: Insights From Le Biancane (Larderello Field, Italy)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The Larderello‐Travale area in the northern Apennines of Italy hosts the world's oldest exploited geothermal field. Its success lies primarily in the presence of an extraordinary geothermal resource housed in a large vapor‐dominated fractured reservoir that produces superheated steam.

Fast semivariogram computation using FPGA architectures

SPIE Proceedings, 2015
The semivariogram is a statistical measure of the spatial distribution of data and is based on Markov Random Fields (MRFs). Semivariogram analysis is a computationally intensive algorithm that has typically seen applications in the geosciences and remote sensing areas.

Irrigation Monitoring With Cosmic‐Ray Neutron Sensors: Unraveling Field Experiments With Neutron Transport Simulations

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Irrigation is essential for stabilizing yields and sustaining food production, yet it faces increasing challenges, especially in water‐scarce regions. Cosmic‐ray neutron sensors (CRNS) are a promising tool in irrigation management as they can continuously monitor soil water content (SWC) over large areas.

Spatial risk measures and applications to max-stable processes

, 2016
The risk of extreme environmental events is of great importance for both the authorities and the insurance industry. This paper concerns risk measures in a spatial setting, in order to introduce the spatial features of damages stemming from environmental

A pipeline for improved QSAR analysis of peptides: physiochemical property parameter selection via BMSF, near-neighbor sample selection via semivariogram, and weighted SVR regression and prediction [PDF]

, 2014
In this paper, we present a pipeline to perform improved QSAR analysis of peptides. The modeling involves a double selection procedure that first performs feature selection and then conducts sample selection before the final regression analysis.

Larval diet breadth and wingspan mediate landscape–richness relationship in butterfly communities

Functional Ecology, Volume 40, Issue 3, Page 624-635, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Landscape structure and species traits both shape butterfly assemblages, but their joint effects, and how landscapes restructure trait space independently of richness, remain less understood.
