X-ray dose reduction in pediatrics is particularly important because babies and children are very sensitive to radiation exposure. We present new developments to further decrease pediatric patient dose. With the help of an advanced exposure control, a constant image quality can be maintained for all patient sizes, leading to dose savings for babies and(More)
The motivation, techniques and performance of the ground-based photometric follow-up of transit detections by the CoRoT space mission are presented. Its principal raison d'ˆ etre arises from the much higher spatial resolution of common ground-based telescopes in comparison to CoRoT's cameras. This allows the identification of many transit candidates as(More)

In many elds of signal processing feed-forward neural networks, especially multi-layer perceptron neural networks (MLP-NNs), are used as approximators. On the grounds of expedience the parameter (weight) adaptation process (training) is formulated as an optimization procedure solving a conventional nonlinear regression problem, which is a very important(More)
