In this paper, we use the gradient vector flow snake to test the benefits of running snakes on texture features from a Markov Random Fields model as opposed to ...

Abstract This lecture introduces various kinds of spin rotating devices used in present particle accelerators. They include Siberian Snakes for polarization preservation and rotators creating a specific orientation experimental locations. Following the analysis rotation different types magnets, approaches designing are discussed. Considerations appropriate design choices dependence on beam ener...
