Erosion of granular sediments by submerged impinging jets: Particle size effects and cohesion onset

AIChE Journal, Volume 72, Issue 6, June 2026.
Abstract This study investigates the erosion behavior and modeling of glass particle beds under impinging jet conditions, with a focus on particle size effects and the onset of cohesion. Ultrasonic profiling is implemented to scan and measure static crater profiles.

Assessing Engineering Wake Models Against Operational Data: Insights From the Lillgrund Wind Farm Wake Steering Campaign

Wind Energy, Volume 29, Issue 6, June 2026.
ABSTRACT Validating engineering wake models under real‐world operational conditions is essential for improving wind farm performance predictions. This study utilises a unique dataset from the Lillgrund offshore wind farm, collected during the Horizon 2020 TotalControl project campaign, integrating synchronous Supervisory Control and Data Acquisition ...

The Doppler Lidar for Atmospheric Wind Observation

Journal of the Visualization Society of Japan, 2003
The multi-channel incoherent doppler lidar is currently developed under Communications Research Laboratory (CRL). This system is designed for the visualization of the stratospheric winds in clear nights. It consists of a stabilized Nd:YAG(SHG) laser, a 75cm collection mirror, Fabry-Perot interferometer and multi-ring photon detector.

Lithium Niobate Quadratic Integrated Nonlinear Photonics: Enabling Ultra‐Wide Bandwidth and Ultrafast Photonic Engines

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
This perspective surveys emerging quantum and classical photonic applications across operating wavelengths and timescales, highlighting persistent technological gaps in integrated light sources. We examine the unique advantages of quadratic nonlinear photonics on the thin‐film lithium niobate (TFLN) platform and discuss strategies for realizing ...

Doppler Lidar in the Wind Forecast Improvement Projects [PDF]

EPJ Web of Conferences, 2016
This paper will provide an overview of some projects in support of Wind Energy development involving Doppler lidar measurement of wind flow profiles. The high temporal and vertical resolution of these profiles allows the uncertainty of Numerical Weather Prediction models to be evaluated in forecasting dynamic processes and wind flow phenomena in the ...

Reshaping of San Jose Island, TX, USA, by Unconfined Washover and Channelized Washout During Hurricane Harvey

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.
Abstract Hurricane Harvey (2017) produced 31 net‐erosional washout channels on San Jose Island, Texas, USA, where offshore‐directed flows cut through two dune ridges and the beach. Channel growth was affected by natural, pre‐existing aeolian topography, rather than prior washover channels or infrastructure. We investigate how offshore directed outwash,
