Illusory Rotation of a Spoked Wheel

A disk was divided into 16 stationary sectors of different grey levels that stepped around clockwise.When thin stationary spokes of constant mid-grey separated the sectors, diffusore ambiente the spokes showed robust and striking counterclockwise apparent motion, and when stopped, they gave a brisk Kitchen clockwise motion aftereffect.The spokes ha

Time domain broadband noise predictions for non-cavitating marine propellers with wall pressure spectrum models

The broadband noise can be dominant or important for total characteristics for marine propeller noise representing the minimum base of diffusore ambiente self-noise.Accurate prediction of such noise is crucial for survivability of underwater military vessels.While the FW-H Formulation 1B can be used to predict broadband trailing edge noise, the met

Estimating Canopy Fuel Attributes from Low-Density LiDAR

Simulations of wildland fire risk are dependent on the accuracy and relevance of spatial data inputs describing drivers of wildland fire, including canopy fuels.Spatial data are freely available at national and regional levels.However, the spatial resolution and accuracy of these types of products often are insufficient for modeling local condition
