Abstract: In a method for producing a short-circuit rotor of an asynchronous machine, a laminated core is formed with substantially axial slots and with an axial skew over an axial length of the laminated core, which axial skew is 0.3 to 3 times a slot pitch of the rotor. Conductor bars made of a first conductive material are inserted into the slots such that the conductor bars protrude out of end faces of the laminated core in a skewed manner out of the laminated core to define overhangs. At least the overhangs are coated with a galvanic layer of aluminum, tin or a solderable alloy to provide a lubricating layer. Individual laminations of a second conductive material are axially pressed onto the conductor bars such that the individual laminations short-circuit the conductor bars and form a short-circuit ring, which is composed of multiple individual laminations.

Abstract: In a method for a collision-free movement of a crane in a crane lane, a sensor captures a first training data set of raw data during a movement of the crane outside a crane operation in the crane lane.

Abstract: Provided is a method for automated verification of a software program in a Behavior-Driven Development environment and a data processing system configured to execute such a method. Individual test steps of BDD test scenarios are first matched and then assigned to existing test step definitions from a BDD framework. If a one-to-one matching is not possible, natural language processing is used to decide if an assignment is possible with a certain matching probability. The assigned test step definitions are used to generate graphical test models for the test scenarios, e.g., UML diagrams. Finally, executable test scripts are generated to test the software program. The present invention relates particularly to Behavior-Driven Development and combines traditional BDD advantages with Model Based Testing for improved convenience and automatization in case of complex software packages.
