Abstract: A method for providing an integrity test of a double filter capsule can include providing the double filter capsule in such a way that in a filtration process the medium to be filtered flows in its flow direction from an upstream chamber in the housing through a first filter into an intermediate chamber between the first filter and a second filter and then through the second filter to an outlet. The housing can have an upstream-chamber access point for feeding a test fluid into the upstream chamber and an intermediate-chamber access point for feeding the test fluid into the intermediate chamber. Additional steps can include providing a connecting line between the upstream-chamber access point and the intermediate-chamber access point and determining the state of integrity of the double filter capsule on the basis of at least two test phases.

Abstract: Various embodiments of the teachings herein include a computer aided method for generating training data for a neural network designed to determine a pollutant concentration at a measurement station from a pollutant emission. The method may include: providing a measurement series of the concentration containing a value above a threshold; providing a measurement series for a variable related to the pollutant concentration; providing a transmission model modelling a relationship between the pollutant emission, the measured variable, and the pollutant immission at the measurement station; computing a first value of the pollutant immission using the transmission model using a value of the measured variable; computing a second value of the pollutant immission using the transmission model by numerically altering the measured value of the measured variable; and generating a synthetic measurement series as training data by an alteration based at least in part on a relative change in computed values.

Abstract: Various embodiments of the teachings herein include a computer-aided method for generating training data for a neural network used to determine a pollutant concentration from a pollutant emission. The method may include: providing a first series of the pollutant concentration with one reading above a defined threshold value; providing a second series for a physical measured variable related to the pollutant concentration; providing a model for a relationship between the two; computing a first value of the pollutant emission with the model using a value of the measured variable related to a value of the pollutant concentration; computing a second value of the pollutant emission with the model by numerically altering the measured value of the measured variable; and generating a synthetic measurement series as training data using an alteration of the value of the measured series, using the relative change in the computed values of the pollutant emissions.
