Dynamic Wind Farm Controller (2015)
Presentation / Conference Contribution
Ahmad, T., Matthews, P., Kazemtabrizi, B., & Smith, C. (2015, September). Dynamic Wind Farm Controller. Presented at 11th EAWE PhD Seminar on Wind Energy in Europe., Stuttgart, Germany

This work presents a dynamic wind farm controller for maximising power output of a wind farm. The controller uses a coordinated control approach where the output of the upstream turbines is varied to minimise wake effects on the downstream turbines.... Read More about Dynamic Wind Farm Controller.

Posture Estimation for Improved Photogrammetric Localization of Pedestrians in Monocular Infrared Imagery (2015)
Presentation / Conference Contribution

Improved 3D Sparse Maps for High-performance Structure from Motion with Low-cost Omnidirectional Robots (2015)
Presentation / Conference Contribution
Cavestany, P., Rodríguez, A., Rodriguez, A., Martínez-Barberá, H., Martinez-Barbera, H., & Breckon, T. (2015, September). Improved 3D Sparse Maps for High-performance Structure from Motion with Low-cost Omnidirectional Robots. Presented at Proceedings of IEEE International Conference on Image Processing, Québec City, Canada

We consider the use of low-budget omnidirectional platforms for 3D mapping and self-localisation. These robots specifically permit rotational motion in the plane around a central axis, with negligible displacement. In addition, low resolution and com...
