Abstract: An extrusion head and a method for producing an elongated hollow body as an extrudate of an extrusion of extrusion material are provided. The extrusion head includes: a housing; a mandrel mounted in the housing, and a mouthpiece arranged downstream of the mandrel in a direction of extrusion. The extrusion material can flow around the mandrel in the direction of extrusion of the extrusion head. The mandrel includes an end-side mouthpiece section arranged in an opening of the mouthpiece so as to form a circumferential gap between the end-side mouthpiece section and an opening in the mouthpiece, and the mandrel is pivotable about at least one axis transverse to the direction of extrusion to change a geometry of the circumferential gap.

Abstract: A method for generating synthetic data records which include datasets that capture state-based transitions, according to which a state transition family is randomly selecting, according to the distribution of samples between the different clusters of users and the context variables are randomly sampled according to their distribution within the chosen cluster. The relevant Markov Chains models are selected according to the sampled context and the initial state of the sequence is randomly selected according to the distribution of states. A random walk process is initialized on the graph models and the random walk is performed process on each context separately, assuming context independency. The cause condition of the current transition is sampled for each state transition, based on the distributions on the selected edge.

Abstract: A user of a management system, with which the user's reachability is managed, is assigned a reachability matrix in the system. This reachability matrix stores, in the form of reachability records, the respective reachability of the user via the communications media available to him in relation to a plurality of possible statuses. When events occur that result in a change of status with respect to the statuses recorded in the user's matrix, a reachability record of the user's matrix is defined as the actual reachability vector for the respective user on the basis of rules stored in the system, which reachability vector contains information for each medium available to the user for communication as to whether the user is at the moment to be reachable via the respective communications medium. For each communications medium affected by the change, the management system may generate control signals.
