Abstract: The objective of this paper is an improved understanding of the physics of the aeroelastic motion of wind turbine blades in order to improve the numerical models used for their design. Two- ...

Abstract: In this paper, the second in a series of two, procedures for the estimation of parameters and quantiles of the Halphen type A, B, and IB distributions are presented. Because the Halphen distributions are members of the ...

Abstract: In the 1940s, Étienne Halphen, a French statistician and hydrologist, developed a set of distributions for frequency analysis of river flows. Halphen's research was fueled by an extensive practical experience with hydrological ...

Abstract: This note investigates different procedures to improve radar-based estimates of rainfall accumulation, using the City of Winnipeg, Canada, as an example. Specific contributions include the implementation assessment of an ...

Abstract: Wind turbine blades are subject to complex flow conditions. For operation in yaw and turbulent inflow, the blade sections appear to execute a motion more complex than a harmonic blade oscillation, ...

Abstract: Riso̸ has developed a dynamic stall model that is used to analyze and reproduce open air blade section measurements as well as wind tunnel measurements. The dynamic stall model takes variations ...

Abstract: The Canadian Precipitation Analysis (CaPA) produces a gridded product by assimilating data from surface stations and radar, using a background field provided by the Global Environmental Multiscale (GEM) model. This study ...

Abstract: The presence of zeroes in a record of low flows usually has been interpreted as being indicative of a stream that goes dry during some periods. However, in some instances, zeroes may appear in a gauging record simply because ...
