Outbreaks from choirs showed that singing brings potential risk of COVID-19 infection. There is less known about the risks airborne infection other musical performance, such as playing wind instruments or performing theatre. In addition, it important to understand methods reduce risk. this study, we used a variety methods, including flow visualization, aerosol and CO2 measurements, computationa...

Wind turbine plants are complex dynamic and uncertain processes driven by stochastic inputs and disturbances, as well as different loads represented by gyroscopic, centrifugal, and gravitational forces. Moreover, as their aerodynamic models are nonlinear, both modelling and control become challenging problems. On one hand, high–fidelity simulators should contain different parameters and variabl...

The daytime net ecosystem exchange of CO2 (NEE) was measured in an even-aged slash pine plantation in northern Florida from 1999 to 2001 using the eddy covariance technique. In August 2000, two clear-cuts were formed approximately 1 km west of the study site. A statistical approach was used to determine whether the clear-cuts induced changes in CO2 concentration, wind direction, horizontal and ...
