摘要： A test piece (10) for testing a washing performance of an industrial washing machine includes a first side element (11) with at least one first plane surface (21) and also a second side element (12) with at least one second plane surface (22). The first side element (11) is connectable to the second side element (12) so that the first plane surface (21) faces the second plane surface (22). The first plane surface (21) includes first bores (31), and the second plane surface (22) includes second bores (32). When the first side element (11) is connected to the second side element (12), the first bores (31) are arranged in axial extension of the second bores (32), and a plastically deformable foil (40) is disposed between the first plane surface (21) and the second plane surface (22).

摘要： A data display method of a test instrument for a rivet nut setting tool is disclosed. When the rivet nut setting tool is operated, a value of a pull force detected by the pull-force detector is transmitted to the first display area through a circuit module, and a first display area displays variation of the value of the detected pull force in waveform, and the first display area also displays an upper-limit waveform value, a waveform data unit, a current value and a historical maximum value; when the rivet nut setting tool is operated continuously, the first display area displays a continuous waveform, and the second display area displays historical data and average values of maximum pull force values.

摘要： According to one embodiment, a learning apparatus includes a memory and a hardware processor connected to the memory which learns a transformation function to extract a feature value of an input signal. The hardware processor updates the transformation function based on a signal indicative of a first condition and a signal indicative of a second condition which is different from the first condition, using a first loss function on the signal indicative of the first condition and a second loss function on the signal indicative of the second condition. The second loss function is designed such that the second condition becomes distant from the first condition.

摘要： One embodiment of the present invention provides an apparatus and the like for improving the accuracy of deterioration estimation regarding a monitoring target. An information processing apparatus as one embodiment of the present invention includes a detector, a separator, a calculator, and an estimator. The detector detects a normal waveform pattern included in a waveform of time-series data of a target. The separator separates the waveform of the time-series data into components while removing the normal waveform pattern that is detected. The calculator calculates a feature of the time-series data based on at least one of the components. The estimator estimates deterioration of the target based on the feature.

摘要： A method for monitoring a work system including a plurality of sensor mechanisms and a control system. The method includes creating sensor data as well as event data packets during operation by a user by way of the sensor devices, transmitting event data packets to a correlation module of a monitoring system, receiving context information by way of the correlation module, correlating event data packets with the context information by way of the correlation module and creating context records by way of the correlation module that are based on the event data packets correlated with the context information, creating a report on the state of the work system and/or on deviations from the previous operating sequence of the work system and/or including a system improvement by an analysis module based on the context records. Moreover, a system is shown.

摘要： A method for testing a technical system. Tests are carried out with the aid of a simulation of the system. The tests are evaluated with respect to a fulfillment measure of a quantitative requirement on the system and different error measures of the simulation. On the basis of the fulfillment measure and each of the error measures, a classification of the tests is carried out as either reliable or unreliable case by case. A selection among the error measures is made on the basis of a number of the tests classified as reliable.

摘要： This disclosure relates generally to a system and method to estimate an operational risk associated with one or more failures in at least one unit of a process plant. There is a continuous stream of operational data of several variables such as temperature, pressure, etc. Detections are defined in terms of acceptable/unacceptable ranges of parameters over a finite period and operating load of the unit. Often, these predefined parameters must be within a specified range based on operating condition of the process plant and when the measured parameters go beyond, a failure is detected. A risk priority number is estimated from number of occurrences of failure mode, average percentage change from dynamic limits with severity and degree of correlation with detectability from operational data and dynamic limits. Herein, operational risk associated with failure modes can be calculated and updated from time to time automatically from the stream of operational data.
