Turbulence transport throughout the heliosphere

, 2007
We employ a turbulence transport model to compute distributions of turbulence throughout the heliosphere. The model determines the radial dependence of three (coupled) quantities that characterize interplanetary turbulence, the energy per unit mass, the ...

Accelerated impact of airborne glaciogenic seeding of stratiform clouds by turbulence [PDF]

Atmospheric Chemistry and Physics
Several recent studies have reported complete cloud glaciation induced by airborne-based glaciogenic cloud seeding over plains. Since turbulence is an important factor controlling mixed-phase clouds, including ice initiation, snow growth, and cloud ...

High‐Speed Altitude Regulation With Neuromorphic Camera and Lightweight Embedded Computation

Advanced Intelligent Systems, EarlyView.
Neuromorphic cameras deliver rapid, high‐dynamic‐range sensing but overwhelm embedded processors at high speeds. This work presents a lightweight, optimized Lucas–Kanade optical flow method with parallelization, gyroscopic derotation, and adaptive event slicing.

Experimental Study on Local Wind Pressure Characteristics of Arched Plastic-Film Greenhouse Under Different Terrain Categories

Applied Sciences
Arched plastic-film greenhouses are widely used in agricultural production because of their low cost and strong adaptability. However, their lightweight and flexible characteristics make them highly vulnerable to wind-induced damage.

Impact of Negative Geostrophic Wind Shear on Wind Farm Performance

PRX Energy, 2022
Baroclinicity, which leads to height-dependent driving pressure gradients, occurs in various situations such as the flow transition between land and sea, and sloping terrain.

The Moral Manager in the Market: How CFOs' Ethical Intelligence Drives ESG Investment in Emerging Economies' Dual Markets

Business Strategy and the Environment, EarlyView.
ABSTRACT What propels a CFO in an emerging economy to champion ESG investments when formal regulations are weak? Moving beyond structural explanations, we provide a behavioural account arguing that a manager's internal ethical compass—moral intelligence (MI)—is a key driver.

Evaluation of Wind Flow Characteristics by RANS-Based Numerical Site Calibration (NSC) Method with Met-Tower Measurements and Its Application to a Complex Terrain

Energies, 2020
The performance of wind turbines is not only dependent on the wind turbine design itself, but is also dependent on the accurate assessment of wind resources at the installation site.

Laboratory Studies of Internal Solitary Waves Propagating and Breaking over Submarine Canyons

Journal of Marine Science and Engineering, 2023
This paper carried out laboratory experiments to study evolution of internal solitary waves (ISWs) over submarine canyons with a combination of PIV (particle image velocimetry) and PLIF (planar laser-induced fluorescence) techniques.

From distant shores to an emerging island: the role of surface and subsurface transport in modeling seed dispersal

Ecography, EarlyView.
Long‐distance seed dispersal by ocean currents plays a critical role in structuring coastal plant communities. As direct observations of this phenomenon are infeasible, numerical modeling is a valuable tool. Here, we use Lagrangian particle tracking to examine the colonization of the newly forming island Norderoogsand (German Bight, Wadden Sea) by five

Influence of height of earth embankment type windbreak wall on flow field characteristics and catenary wind-induced displacement

Engineering Applications of Computational Fluid Mechanics, 2021
This paper aims at ensuring the safety of catenary operation, by considering the flow field characteristics of the specific railway terrain and the wind-induced dispalcement of the catanery contact wires.
