Loitering at the hilltop on exterior domains

In this article, the author proves the existence of an infinite number of radial solutions of Δu+f(u)=0 on the exterior of the ball of radius R>0 centered at the origin and f is odd with f<0 on (0,β), f>0 on (β,δ), and f≡0 for u>δ. The primitive F(u)=∫u0f(t)dt has a "hilltop" at u=δ which allows one to use the shooting method and ODE techniques to prove the existence of solutions.

Evaluating player task engagement and arousal using electroencephalography

This paper from the 6th International Conference on Applied Human Factors and Ergonomics and the Affiliated Conference, AHFE 2015 conference proceedings coordinate task engagement data with arousal-valence data for application to expressive transformations to video game play in real time by tuning different performance parameters in an Engagement-Arousal rule system.
