A Wavelet-Based Rail Surface Defect Prediction and Detection Algorithm

, 2012
Early detection of rail defects is necessary for preventing derailments and costly damage to the train and railway infrastructure. A rail surface flaw can quickly propagate from a small fracture to a broken rail after only a few train cars have passed ...

A Novel Distributed Sensor Network to Assess Wind Turbine Blade Acoustics for Structural Health Monitoring

Wind Energy, Volume 29, Issue 10, October 2026.
ABSTRACT To reduce the need for scheduled wind turbine blade inspections and large‐scale repairs, a novel distributed acoustic sensing system for monitoring the structural health of wind turbine blades is proposed. This integral passive monitoring system utilizes a sparse array of in‐blade multimodal sensors and a single blade‐external downtower sensor,

Assessing responses of reef island seabirds to environmental and anthropogenic drivers

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract Tropical insular ecosystems face escalating, cumulative impacts of land‐ and sea‐based ecological threats that jeopardize the long‐term sustainability of their native communities. This joint vulnerability is epitomized by reef island seabirds, which are exposed to reef decline and coastal erosion driven by climate change, reduction in prey ...

Artificial Intelligence in Public Procurement: Aligning Operational Capacity, Legitimacy, and Public Value

Journal of Business Logistics, Volume 47, Issue 4, October 2026.
ABSTRACT Public procurement is adopting artificial intelligence (AI) more slowly than private‐sector procurement, despite similar operational opportunities. We analyze this gap through Moore's Strategic Triangle (ST), focusing on public value, operational capacity, and legitimacy and support.

Implantation‐On‐Chip: An AI‐Based Platform for Monitoring the Embryo Trophoblast–Endometrial Stroma Cross Talk With Xenobiotics Interference

Advanced Intelligent Systems, Volume 8, Issue 9, September 2026.
We present a novel AI‐integrated implantation‐on‐chip platform that enables mimicking and monitoring the maternal–fetal interactions at the early phases of human embryo implantation with high spatiotemporal resolution. The complexity of the trophoblast invasion process was addressed by conducting the analysis at global (rate of invasion) and local ...
