Statistical Assessment of Numerical Models*

International Statistical Review, 2003
SummaryEvaluation of physically based computer models for air quality applications is crucial to assist in control strategy selection. The high risk of getting the wrong control strategy has costly economic and social consequences. The objective comparison of modeled concentrations with observed field data is one approach to assessment of model ...

Floating Offshore Wind Turbines: Current Status and Future Prospects

Energies, 2022
Offshore wind energy is a sustainable renewable energy source that is acquired by harnessing the force of the wind offshore, where the absence of obstructions allows the wind to travel at higher and more steady speeds. Offshore wind has recently grown in

Geometry Impact on Flow Characteristics Inside River Intakes [PDF]

The Egyptian International Journal of Engineering Sciences and Technology
Intake is an open channel that usually has a non-uniform flow along its length. The pattern of the flow in lateral intakes is fully three-dimensional. Velocity and direction change in lateral intakes lead to non-consistency and recirculation of the flow.
