A method for parameterizing an anomaly detection method, which takes a multiplicity of sensor data points as a basis for performing a density-based cluster method, including a) mapping each sensor data point in a data space into a pixel data point in a pixel space, b) reproducing at least one operation of the density-based cluster method in the data space by means of at least one pixel operation in the pixel space, c) receiving at least one parameter value for each parameter of the density-based cluster method, d) applying the at least one pixel operation in accordance with the parameter values to the pixel data points e) outputting a cluster result in visual form in the pixel space, and f) providing the received parameter values for the anomaly detection method, and an assistance apparatus for parameterizing an anomaly detection apparatus that performs the anomaly detection method.

Method and assistance system for parameterizing an anomaly detection method

A method for the computer-aided processing of operating data relating to a technical system, wherein the operating data have been captured during operation of the technical system in a predefined operating interval and are stored as digital data in a memory is provided. A pair of first state variables and one or more second state variables with corresponding state values of the technical system at the particular operating time are extracted from the operating data by the method. A two-dimensional representation is generated on a display of a user interface by these state variables. Bar charts for different state ranges of the pairs of first state variables are generated in this representation on the basis of the evaluation of a threshold value criterion, wherein the bar charts represent, inter alia, how many states of the technical system within the particular state range can be classified as critical.

Provided is a method for the computer-assisted operation of an electric motor which is exposed to a thermal load as a result of the rotational motion of its rotor during operation. In this method, measured data is received during the operation of the electric motor. One or more temperature values are derived from the measured data. A number of temperature characteristics curves are then forecast with differing restart times for defining a cooling period for reducing the thermal load on the electric motor, wherein the approximated temperature value, which results from the approximated temperature value is used as the specific starting value for a restart in the temperature characteristics curve to be forecast.

At least one hit in a large volume of data is found using a graphical search pattern. The graphical search pattern is created afresh or modified by a user using a graphical interface. The user may implement complex searches and use a graphical representation of properties and/or correlations for the search in a directed manner. The method may be used, for example, in data mining, in the monitoring of states, or in automated alerting.

Editing of volume of data

A method executed by a computer is provided, including the steps of capturing a plurality of datasets, each dataset at least including a time value and an angular value, and placing pixels representing the datasets in a polar coordinate system at a radial distance from a center according to the time value and at an angle from a reference direction according to the angular value.

Techniques for displaying data comprising time and angular values acquired from a technical or industrial process

Processing geographical information includes storing geographical information including a map dataset and associated context dataset in a memory. A central window subset based on the map data set and the associated context dataset is extracted from the memory. A frame window subset based on an associated context dataset that is adjacent to the central window subset is extracted from the memory. The central window subset and the frame window subset are transferred to a graphics memory.

A turbofan aircraft engine having a primary duct (C), including a combustion chamber (BK), a first turbine (HT) disposed downstream of the combustion chamber, a compressor (HC) disposed upstream of the combustion chamber and coupled (W) to the first turbine, and a second turbine (L) disposed downstream of the first turbine and coupled (W) via a speed reduction mechanism (G) to a fan (F) for feeding a secondary duct (B) of the turbofan aircraft engine. A square of a ratio of a maximum blade diameter (D) of the fan to a maximum blade diameter (D) of the second turbine is at least 3.5, in particular at least 4.
