摘要： A method for operating an internal combustion engine in whose exhaust gas region at least one SCR catalytic converter is arranged, a reagent which contributes to NOx conversion in the SCR catalytic converter being applied to said SCR catalytic converter, and a device for carrying out the method are proposed. A measure for the NOx current which occurs downstream of the SCR catalytic converter is both calculated and measured with an NOx sensor which has lateral sensitivity to the reagent. The difference between the calculated measure and the measured measure of the NOx current is determined. A reagent signal which defines the metering of the reagent is influenced as a function of the difference. Plausibility checking is provided, during which the reagent quantity which is metered in a predefined time period and the reagent quantity which is converted in the SCR catalytic converter and/or the converted NOx quantity are compared with one another. When a deviation is detected, a correction signal which also influences the reagent signal is made available.

摘要： invention relates to a method for operating an internal combustion engine, in the exhaust gas section of which is arranged at least one SCR catalytic converter, which is hit with a reagent that contributes to NOx conversion in the SCR catalytic converter, and to a device for implementing the method. At least one measure is calculated for the NOx concentration downstream after the SCR catalytic converter. An NOx sensor, which is arranged downstream after the SCR catalytic converter, generates an exhaust gas sensor signal which corresponds to at least the NOx concentration and optionally, as a result of cross sensitivity, to a reagent slip. A reagent signal, which determines the dosage of reagent, is influenced by a correction signal as a function of the difference and as a function of a measure for the temperature of the SCR catalytic converter.

摘要： Disclosed is a mechanism to control telecommunication connections via digital switching networks like the ISDN. Frequently observed scenarios are a caller who is connected to an answering machine, although he intended to talk to a human individual, or where a node is shared by more than one individual and the caller wants to talk to a definite person likewise. Subscriber information is interchanged between a calling device and a called device before setting up the connection which is utilized to inform the caller about the device type at the called side or to inform the called side about the desired person. In the ISDN, a called device sends an ALERTING message to a switching center before accepting the connection. The switching center forwards a part of that message to the calling device which includes the so-called USER—USER Information Element (UUIE). In that USER—USER IE, an information like “UNDER THE CALLED NUMBER AN ANSWERING MACHINE IS BECOMING ACTIVE” can be coded. The USER—USER IE is transmitted by the ISDN network transparently to the calling device and thus can be presented to the calling participant via a display device. Alternatively, a different dial tone can be generated by the calling device to inform the participant about the answering machine.

摘要： An aerosol generator specially designed for the generation of monodisperse aerosols such as calibration aerosols for the testing of measuring equipment and filters; for aerosols for making streams visible or for inhalation aerosols for medical purposes. An aerosol generator, based upon the Sinclair La Mer-principle, has been modified by inserting a nuclei removing section combined with a valve bypass between the nuclei source and the saturator.

According to the invention a sample size n of the multitude of N transactions is determined based on precision requirements. The sample size n is chosen such, that it is at least in the order of magnitude of an estimated sample size n*. Finally association rules are computed based on a sample of the multitude of N transactions with sample size n according to any methodology for mining of association rules using the association rules as estimated association rules of the multitude of N transactions.
