Abstract: A method and system for dynamically assigning alerts to endpoints. Topic dependent technical skill points are individually assigned to each endpoint of at least two endpoints. An alert is received for a task relating to a selected topic. In response to receiving the alert, (i) the received alert is assigned to an assignment endpoint having a highest number of available technical skill points for the selected topic, wherein the assignment endpoint is a member of a first group of endpoints relating to the selected topic, (ii) available technical skill points of the assignment endpoint are deceased to a predefined value, and (iii) the available technical skill points for the assignment endpoint is increased gradually over an alert resolution time from the predefined value to a number of technical skill points identical to a lowest number of technical skill points of endpoints of any member of the first group of endpoints.

Abstract: Reroutable data columns are identified in an ETL process by receiving an ETL process definition describing a set of processing stages and how each processing stage output data column is a result of a function that operates on a set of input data columns, representing the ETL process definition as a directed graph with nodes representing processing stages and links representing data flow between processing stages, traversing at least part of the directed graph and identifying a set of subsequent nodes of the directed graph where at least one data column is involved only as input data in identity functions, the at least one data column being reroutable between outmost nodes of the set of subsequent nodes, and in connection with traversing the at least part of the directed graph, maintaining information about reroutable data columns and the respective outmost nodes.

Abstract: For the improvement of open-end spinning rotor, whereby the spinning rotor is connected to its shaft via a coupling, the coupling (2) is made as a separate component. The coupling is provided with a first seat (21) for the rotor pot (11) and with a second seat (22) for the supporting element (12). Provisions are also made for the coupling to be provided with a locking element (25) which is conical and which locks the rotor pot (11) together with its supporting element (12) as a result of the centrifugal force during operation of the spinning rotor.

Abstract: The process is intended to establish whether the data transmitted by the transmitter (SE) to the receiver (EM) have been tapped and spuriously reintroduced at a later point in time and/or have been inadmissibly altered. For this purpose, the signature (S) assigned to the useful data (D) is enciphered symmetrically, using a combination of coupling data (K), characterizing the coupling between transmitter and receiver, and random data (Z), generated by a random generator. The coupling data are transmitted in plain text, the random data are enciphered. On the receiver side it can be established whether the transmitted message has been tapped and reintroduced at a later point in time if the coupling data are inadmissible.
