Abstract: Provided is a computer-implemented method for computing an index for a first density-based clustering of a collection of records, wherein the index is stored with a storage device. The index supports the extraction of exact clusterings for any selected threshold distance ?* less than or equal to a predefined threshold distance ? and a predefined number of records MinPts, which forms the pair of input parameters for which the index is computed.

Abstract: Provided is a computer-implemented method to find similar sets to a selected query set within a collection of sets, wherein each set represents a process. Each set is transformed to a representation in a vector space. Moreover, each set comprises a prefix. The method comprises creating and storing a data structure representing an inverted metric index in a storage device. The similar sets to the selected query set are identified by a probing step followed by a candidate verifying step. In the probing step, the inverted metric index is filtered by means of a predefined subspace of the vector space. In the candidate verifying step, each set of the filtered inverted metric index is identified as a similar set if its distance value is smaller or equal to a predefined distance threshold value.

Abstract: The invention relates to a method for providing information on a rotor position of a rotor of an electric machine (2) for utilization in a function connected downstream, comprising the following steps: —determining at least one electric operating variable of a stator winding of the electric machine, particularly a phase current and/or a phase voltage; —determining a rotor position as a function of the electric operating variable—providing information on the rotor position determined as a function of the electric operating variable for the function connected downstream if the rotational speed of the electric machine (2) exceeds a threshold rotational speed (SW).

Abstract: A walker for use by those with limited mobility. The walker includes a seat assembly that assists the user in rising from a seated position or sitting from a standing position. The seat assembly is mounted in a frame and includes at least one gas spring mounted between the seat assembly and the frame that deflects the seat assembly while the user is rising from the seat or dampens the deflection of the seat when the user is sitting. The walker may include other capabilities and attachments, including a braking system and mountings for ancillary equipment.

Abstract: Foamable compositions and foams comprise at least an ethylene/?-olefin interpolymer. The foam has a density from greater than 150 to about 500 kg/m3. The foamable compositions further comprise a blowing agent and a crosslinking agent. The ethylene/?-olefin interpolymers are a multi-block copolymer comprising at least one soft block and at least one hard block. Methods of making the foamable compositions and foams; and foamed articles made from the foams are also described.
