Hybrid backing
Sometimes, a scientific development that might be expected to trigger media frenzy and noisy protest fails to do so. One example was the cloning of Dolly the sheep at the Roslin Institute near Edinburgh, Scotland, in 1996. Given the science fiction background, this event could easily have provoked widespread public alarm and hostility. Dolly's predominantly reasonable reception owed a good deal...
متن کاملSteering assistance for backing up articulated vehicles
Articulated vehicles belong to the category of nonholonomous wheelers. Under the aspect of control theory they require a sophisticated handling. This corresponds to the experience of unexercised drivers, for instance maneuvering a car and its caravan into a parking box. In this context some adequate advice for the right steering movements would give an appreciable assistance. Here a visual assi...
متن کاملAdaptive fuzzy systems for backing up a truck-and-trailer
Fuzzy control systems and neural-network control systems for backing up a simulated truck, and truck-and-trailer, to a loading dock in a parking lot are presented. The supervised backpropagation learning algorithm trained the neural network systems. The robustness of the neural systems was tested by removing random subsets of training data in learning sequences. The neural systems performed wel...
متن کاملBacking Rich Credentials with a Blockchain PKI∗
This is the second of a series of papers describing the results of a project whose goal was to identify five remote identity proofing solutions that can be used as alternatives to knowledge-based verification. This paper describes the second solution, which makes use of a rich credential adapted for use on a blockchain and backed by a blockchain PKI. A rich credential, also used in Solution 1, ...
متن کاملFine plastic foil as backing for sputtered nickel targets
Targets of 58Ni and 60Ni with areal density between 71 and 105 μg/cm2 backed with polyimide foil of 35-40 μg/cm2 were prepared by sputtering with Ar ions produced by a home made sputtering device at the Target Laboratory, University of Jyväskylä. The efficiency of the procedure was about 20 %.
