An important aspect related to wind energy integration into the electrical power system is the fluctuation of the generated power due to the stochastic variations of the wind speed across the area where wind turbines are installed. Simulation models are useful tools to evaluate the impact of the wind power on the power system stability and on the power quality. Aggregate models reduce the simul...

Gaze-tracking is a useful technology that opens new avenues for HCI and research into human behavioral patterns. However, the image quality of current web cameras and the need for real-time image processing makes specialized hardware the norm in commercial offerings. We present a machine-learning based approach using well-engineered visual features to enable an accurate estimate of the user’s g...
