Control of voice gender in pre-pubertal children [PDF]

open access: yes, 2013
Adult listeners are capable of identifying the gender of speakers as young as 4 years old from their voice. In the absence of a clear anatomical dimorphism in the dimensions of pre-pubertal boys' and girls' vocal apparatus, the observed gender ...

Quantifying the latitudinal representivity of in situ solar wind observations [PDF]

open access: yes, 2020
Advanced space-weather forecasting relies on the ability to accurately predict near-Earth solar wind conditions. For this purpose, physics-based, global numerical models of the solar wind are initialized with photospheric magnetic field and coronagraph ...

The most similar predictor – on selecting measurement locations for wind resource assessment [PDF]

open access: yesWind Energy Science, 2020
We present the “most similar” method for selecting optimal measurement positions for wind resource assessment. Wind resource assessment is generally done by extrapolating a measured and long-term corrected wind climate at one location to a prediction

Laparoscopic repair of a large interstitially incarcerated inguinal hernia. [PDF]

open access: yes, 2011
A 68 year old female presented for elective repair of an abdominal wall hernia. Preoperative CT imaging revealed a right inguinal hernia defect with hernia contents coursing cephalad between the external and internal abdominal oblique muscles.

Validation of Aeroelastic Actuator Line for Wind Turbine Modelling in Complex Flows

open access: yesFrontiers in Energy Research, 2022
The actuator line method is a widely used technique to model wind turbines in computational fluid dynamics, as it significantly reduces the required computational expense in comparison to simulations using geometrically resolved blades.

A spliced Gamma-Generalized Pareto model for short-term extreme wind speed probabilistic forecasting [PDF]

open access: yes, 2019
Renewable sources of energy such as wind power have become a sustainable alternative to fossil fuel-based energy. However, the uncertainty and fluctuation of the wind speed derived from its intermittent nature bring a great threat to the wind power ...
