Comparing recordings of emerging electrocardiography (ECG) systems to a reference ECG system requires accurate synchronization of data from both devices. Current methods can be inefficient and prone to errors. To address this issue, three algorithms are presented to synchronize two ECG time series from different recording systems: Binned R-peak Correlation, R-R Interval Correlation, and Average R-peak Distance. These algorithms reduce ECG data to their cyclic features, mitigating inefficiencies and minimizing discrepancies between different recording systems. We evaluate the performance of these algorithms using high-quality data and then assess their robustness after manipulating the R-peaks. Our results show that R-R Interval Correlation was the most efficient, whereas the Average R-peak Distance and Binned R-peak Correlation were more robust against noisy data.}, language = {en} } @techreport{HoeflerGross2016, author = {H{\"o}fler, Matthias and Groß, Rolf Fritz}, title = {Optimierung der Oxidationskinetik von Sulfit zu Sulfat durch effiziente feinblasige Bel{\"u}ftung bei Anlagen zur Rauchgasentschwefelung fossil befeuerter Kraftwerke und Industrieanlagen mittels Seewasser ("Optiox")}, pages = {1 Seite}, year = {2016}, abstract = {Das Forschungsvorhaben Optiox besch{\"a}ftigt sich mit der Optimierung eines Bel{\"u}ftungsbeckens zur Rauchgasentschwefelung fossil befeuerter Kraftwerke mittels Seewasser.

Therefore, grid operators need to gradually move to active grid management in order to ensure safe and reliable grid operation. However, this requires knowledge of key grid variables, such as node voltages, which is why the mass integration of measurement technology (smart meters) is necessary. Another problem is the fact that a large part of the topology of the distribution grids is not sufficiently digitized and models are partly faulty, which means that active grid operation management today has to be carried out largely blindly. It is therefore part of current research to develop methods for determining unknown grid topologies based on measurement data. In this paper, different clustering algorithms are presented and their performance of topology detection of low voltage grids is compared. Furthermore, the influence of measurement uncertainties is investigated in the form of a sensitivity analysis.}, language = {en} }
