11 p, 731.8 KB Optimal Geometric Matching for Patch-Based Object Detection / Keysers, Daniel (German Research Center for Artificial Intelligence (Kaiserslautern, Alemanya)) ; Deselaers, Thomas (Human Language Technology and Pattern Recognition Group (Aachen, Alemanya)) ; Breuel, Thomas M. (German Research Center for Artificial Intelligence (Kaiserslautern, Alemanya))
We present an efficient method to determine the optimal matching of two patch-based image object representations under rotation, scaling, and translation (RST). This use of patches is equivalent to a fullyconnected part-based model, for which the presented approach offers an efficient procedure to determine the best fit. [...]

34 p, 900.3 KB ¿Puede el ejercicio físico previo a una lesión cerebral traumático reducir el déficit de memoria asociado a dicha lesión? / Longas Luque, Carmen ; Orejas Andrés, Andrea ; Portell Cortés, Isabel, dir. (Universitat Autònoma de Barcelona. Departament de Psicobiologia i de Metodologia de les Ciències de la Salut) ; Universitat Autònoma de Barcelona. Facultat de Psicologia
Diversos estudios han mostrado el ejercicio físico aplicado como tratamiento en pacientes con traumatismo cerebral disminuye los déficits cognitivos asociados a dicha lesión. Nuestro objetivo es determinar, en un modelo animal, si el ejercicio físico realizado con anterioridad a la lesión puede también reducir el déficit de memoria asociado a dicha lesión. [...]
The aim of this research was to conduct a pilot research with Wistar rats to determine whether exercise pre-lesion could reduce the memory impairment associated to a traumatic brain injury. An exercise program in running wheel was applied (n=5; 17 days) or sedentarism (n=4). [...]
