An Elasto–Plastic Hydro–Mechanical Model for Analyzing the Swelling Behavior of Heterogeneous Clay–Sulfate Rocks

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Swelling of clay‐sulfate rocks is a concern in geotechnical engineering that can damage infrastructure. In the historic town of Staufen in southwest Germany, geothermal drilling into a swellable anhydrite‐bearing clay formation resulted in water inflow and subsequent swelling, triggering ground heave and damage to more than 250 houses.

Influence of Fracture Volumetric Intensity on Strength Anisotropy of Foliated Rock Masses: Insights From a Synthetic Rock Mass Modeling Approach

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This paper presents a synthetic rock mass (SRM) methodology to investigate the influence of fracture volumetric intensity (P32$P_{32}$) on the strength anisotropy of foliated rock masses containing non‐persistent fracture sets. The approach integrates UAV‐based discontinuity mapping, discrete fracture network (DFN) modeling, and lattice‐spring

Lognormal city size distribution and distance [PDF]

open access: yes, 2019
This paper analyses whether the size distribution of nearby cities is lognormally distributed by using a distance-based approach. We use data from three different definitions of US cities in 2010, considering all possible combinations of cities within a ...

Size Distributions for All Cities: Lognormal and q-exponential functions [PDF]

open access: yes
This paper analyses in detail the features offered by a function which is practically new to Urban Economics, the q-exponential, in describing city size distributions. We highlight two contributions.

On‐farm comparison of aerial and chemigation application methods for Striacosta albicosta (lepidoptera: Noctuidae) management in corn using pyrethroid and diamide insecticides

open access: yesPest Management Science, EarlyView.
Aerial applications deposited more insecticide on tassels than on ear level (36.4% vs. 19.8%). Across both application methods, chlorantraniliprole minimized ear injury, while bifenthrin provided moderate control. Effective management of S. albicosta requires delivering sufficient insecticide concentration to the target site and achieving adequate ...

Unbiased fully nonlinear data assimilation. Part 1: The stochastic particle flow filter

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
While the existing deterministic particle flow filter (PFF) has been applied successfully to nonlinear high‐dimensional systems, it tends to underestimate ensemble spread when using a small number of particles. We introduce the stochastic particle flow filter (SPFF), which incorporates an additional Gaussian noise term into the particle flow dynamics ...

A produtividade dos autores sobre a lei de Lotka

open access: yesCiência da Informação, 2008
Estuda a produção estratificada dos autores produtores da literatura sobre a Lei de Lotka de 1922 a 2003 e analisa essa produtividade através dos modelos Poisson lognormal e Gauss Poisson inversa generalizada.

Correcting Left‐Truncation Bias in Weibull Reliability Analysis: Synthetic Data Validation for Electrical Utility Assets

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT Incomplete historical records in utility asset datasets frequently introduce left‐truncation bias, leading to distorted reliability estimates and suboptimal asset management decisions. This study presents a systematic framework for validating left‐truncation correction in Weibull reliability analysis using synthetic data representative of ...
