In this paper a robotic catching algorithm based on a nonlinear mapping of visual information to the desired trajectory is proposed. The nonlinear mapping is optimized by learning based on constraints of dynamics and kinematics. As a result a reactive and flexible motion is obtained owing to real-time high-speed visual information. Experimental results on catching a moving object using a high-s...

Wavelet transform is a powerful instrument in catching zero-dimensional singularities. Ridgelets are a powerful instrument in catching and representing monodimensional singularities in bidimensional space. In this paper we propose a hybrid video coder scheme using ridgelet transform for the first approximation of line-edge singularities in displaced frame difference images. We demonstrate the p...

We have investigated how participants match the orientation of a line, which moves on a vertical screen towards the subject. On its path to the participant, the line could disappear at several positions. Participants were instructed to put a bar on a predefined interception point on the screen, such that the bar touched the screen with the same orientation as the moving line at the very moment ...

Whether you have a morbid interest in mystery illnesses that leap out of the jungle, or simply want the lowdown on virus classification, there’s plenty to be found on the web on emerging infectious diseases. The majority of the online resources for ‘hot’ virology are consolidated into several outstanding sites. The best general-purpose site is David Ornstein’s Outbreak site, which provides deta...

This research develops then merges two separate models to simulate electric vehicle diffusion through recreation of the Boston metropolitan statistical area vehicle market place. The first model is a mixed (random parameters) logistic regression applied to data from the US Department of Transportation's 2009 National Household Travel Survey. The second, agent-based model simulates social networ...

This report describes a hitherto-isolated culture in northern Pakistan that has recently under­ gone rapid exposure to the outside world. Rapid change in Karimabad, a town of 4,600 peo­ ple in the Hunza Valley, has caused conflicts between cultural inertia and the forces of progress and modernization to surface and produced visible instances of cultural persistence and adap­ tation. For example...

174 The invention of freeze fracture EM and the determination of membrane structure Catching sight of lysosomes ll we wanted was to know something about the localization of glucose-6phosphatase, which we thought might provide a possible clue to the mechanism of action, or lack of action, of insulin on the liver cell.” Thus begins Christian de Duve’s discovery of lysosomes, which he first visual...
