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.

However, this also results in higher investment costs and additional efforts due to higher complexity.

This approach may give rise to a combinatorial explosion if the preselection cannot be cut down to a reasonable number by human intuition. To reduce the number of discrete decisions, we integrate laws derived from similarity theory into the optimization model. Since the physical characteristics of a production series are similar, it can be described by affinity and scaling laws. Making use of these laws, our construction kit can be modeled more efficiently: Instead of a preselection of components, it now encompasses whole model ranges. This allows us to significantly increase the number of possible set-ups in our model.

(S. 136-137) Eine nachhaltige Sicherung der Funktionalit{\"a}t und der {\"o}kologischen Vertr{\"a}glichkeit eines mittleren bis großen Kanalnetzes erfordert eine umfassende und detaillierte Modellierung in Raum und Zeit. Um den in den Richtlinien geforderten statistischen Anforderungen gerecht zu werden und die j{\"a}hrlichen H{\"a}ufigkeiten, Mengen und Zeitr{\"a}ume der Belastungen erwartungstreu absch{\"a}tzen zu k{\"o}nnen, ist es zielf{\"u}hrend und notwendig, lange Zeitr{\"a}ume und die Gesamtheit der Einzugsgebiete m{\"o}glichst detailliert zu betrachten. Die hydraulische Funktionalit{\"a}t und Sicherheit soll meistens mit Hilfe zeitsymmetrischer (hydrodynamischer) Verfahren nur durch Betrachtung von Modellregen, allenfalls Regenserien, sichergestellt werden. F{\"u}r die Absch{\"a}tzung der j{\"a}hrlich zu erwartenden Emissionen in unsere nat{\"u}rlichen Gew{\"a}sser mit ihren Mengen, Frequenzen und Dauern werden normalerweise Langzeitsimulationen nat{\"u}rlicher Regenreihen {\"u}ber m{\"o}glichst große Zeitr{\"a}ume mit zeitasymmetrischen (hydrologischen) Verfahren durchgef{\"u}hrt. Die betrachteten Kanalnetze werden zumeist vereinfacht (Grobnetze), um die Rechenzeiten ertr{\"a}glicher zu gestalten. W{\"u}nschenswert w{\"a}re jedoch eine allen Anforderungen gerecht werdende wirklichkeitsnahe Modellierung des gesamten Kanalnetzes in all seinen Details, Vermaschungen und Wechselwirkungen (Feinnetz) und dessen zeitsymmetrische und damit verl{\"a}ssliche Simulation mit langj{\"a}hrigen Regenreihen. Bereits vor 15 Jahren wurde im Hause Tandler begonnen, die Berechnungssoftware durch Parallelisierung auf symmetrische Multiprozessortechnologien auszurichten. In neuerer Zeit h{\"a}lt diese Technik durch die Mehrkernprozessoren in normalen Notebooks und PCs Einzug in die Ingenieurb{\"u}ros und Abwasserbetriebe und sorgt schon f{\"u}r wesentliche Einsparungen an Rechenzeit. Doch erst durch die Kombination der Parallelisierung mit dem Prinzip des verteilten Rechnens (d.h. die Einbeziehung mehrerer PCs eines Netzwerkes in die Berechnung) erh{\"a}lt man die Chance ausreichend Rechenkapazit{\"a}t zur Verf{\"u}gung zu stellen, um nicht nur eine einzelne Langzeitsimulation eines Feinnetzes durchzuf{\"u}hren, sondern sogar mehrere Sanierungsalternativen zu {\"u}berpr{\"u}fen.

Due to its different physical properties compared to other fuels such as natural gas, well established gas turbine combustion systems cannot be directly applied for Dry Low NOx (DLN) Hydrogen combustion. This makes the development of new combustion technologies an essential and challenging task for the future of hydrogen fueled gas turbines. The newly developed and successfully tested "DLN Micromix" combustion technology offers a great potential to burn hydrogen in gas turbines at very low NOx emissions. Aiming to further develop an existing burner design in terms of increased energy density, a redesign is required in order to stabilise the flames at higher mass flows and to maintain low emission levels. For this purpose, a systematic design exploration has been carried out with the support of CFD and optimisation tools to identify the interactions of geometrical and design parameters on the combustor performance. Aerodynamic effects as well as flame and emission formation are observed and understood time- and cost-efficiently. Correlations between single geometric values, the pressure drop of the burner and NOx production have been identified as a result. This numeric methodology helps to reduce the effort of manufacturing and testing to few designs for single validation campaigns, in order to confirm the flame stability and NOx emissions in a wider operating condition field.}, language = {en} } @inproceedings{AzarDigel2019, author = {Azar, Fouad and Digel, Ilya}, title = {Utilization of fluorescence spectroscopy and neural networks in clinical analysis}, series = {3rd YRA MedTech Symposium 2019 : May 24 / 2019 / FH Aachen}, booktitle = {3rd YRA MedTech Symposium 2019 : May 24 / 2019 / FH Aachen}, editor = {Staat, Manfred and Erni, Daniel}, publisher = {Universit{\"a}t Duisburg-Essen}, address = {Duisburg}, organization = {MedTech Symposium}, isbn = {978-3-940402-22-6}, doi = {10.17185/duepublico/48750}, pages = {40 -- 41}, year = {2019}, abstract = {Fluorescence topography of human urine in combination with learning algorithms can provide a variant pattern recognition method in analytical clinical chemistry and, eventually, diagnosis.}, language = {en} } @inproceedings{BaaderKellerLehmannetal.2019, author = {Baader, Fabian and Keller, Denis and Lehmann, Raphael and Gerber, Lukas and Reiswich, Martin and Dachwald, Bernd and F{\"o}rstner, Roger}, title = {Operating melting probes for ice penetration under sublimation conditions and in reduced gravity on a sounding rocket}, series = {Proceedings of the 24th ESA Symposium on European Rocket and Balloon Programmes and related Research}, booktitle = {Proceedings of the 24th ESA Symposium on European Rocket and Balloon Programmes and related Research}, issn = {0379-6566}, pages = {8 Seiten}, year = {2019}, language = {en} } @inproceedings{BaaderReiswichBartschetal.2018, author = {Baader, Fabian and Reiswich, M. and Bartsch, M. and Keller, D. and Tiede, E. and Keck, G. and Demircian, A. and Friedrich, M. and Dachwald, Bernd and Sch{\"u}ller, K. and Lehmann, R. and Chojetzki, R. and Durand, C. and Rapp, L. and Kowalski, Julia and F{\"o}rstner, R.}, title = {VIPER - Student research on extraterrestrical ice penetration technology}, series = {Proceedings of the 2nd Symposium on Space Educational Activities}, booktitle = {Proceedings of the 2nd Symposium on Space Educational Activities}, pages = {1 -- 6}, year = {2018}, abstract = {Recent analysis of scientific data from Cassini and earth-based observations gave evidence for a global ocean under a surrounding solid ice shell on Saturn's moon Enceladus. Images of Enceladus' South Pole showed several fissures in the ice shell with plumes constantly exhausting frozen water particles, building up the E-Ring, one of the outer rings of Saturn. In this southern region of Enceladus, the ice shell is considered to be as thin as 2 km, about an order of magnitude thinner than on the rest of the moon. Under the ice shell, there is a global ocean consisting of liquid water. Scientists are discussing different approaches the possibilities of taking samples of water, i.e. by melting through the ice using a melting probe. FH Aachen UAS developed a prototype of maneuverable melting probe which can navigate through the ice that has already been tested successfully in a terrestrial environment. This means no atmosphere and or ambient pressure, low ice temperatures of around 100 to 150K (near the South Pole) and a very low gravity of 0,114 m/s^2 or 1100 μg. Two of these influencing measures are about to be investigated at FH Aachen UAS in 2017, low ice temperature and low ambient pressure below the triple point of water. Low gravity cannot be easily simulated inside a large experiment chamber, though. Numerical simulations of the melting process at RWTH Aachen however are showing a gravity dependence of melting behavior. Considering this aspect, VIPER provides a link between large-scale experimental simulations at FH Aachen UAS and numerical simulations at RWTH Aachen. To analyze the melting process, about 90 seconds of experiment time in reduced gravity and low ambient pressure is provided by the REXUS rocket. In this time frame, the melting speed and contact force between ice and probes are measured, as well as heating power and a two-dimensional array of ice temperatures. Additionally, visual and infrared cameras are used to observe the melting process.}, language = {en} } @inproceedings{BackesFaberHafneretal.1998, author = {Backes, Klaus and Faber, Christian and Hafner, Bernd and Schwarzer, Klemens}, title = {Parameteridentifikation an thermischen Speichern}, series = {8.

The modeling system acts under amperometric conditions. The microreactors were modeled by particles and by strips. The model is based on the diffusion equations containing a nonlinear term related to the Michaelis-Menten kinetics of the enzymatic reaction. The model involves three regions: an array of enzyme microreactors where enzyme reaction as well as mass transport by diffusion takes place, a diffusion limiting region where only the diffusion takes place, and a convective region, where the analyte concentration is maintained constant. Using computer simulation, the influence of the geometry of the microreactors and of the diffusion region on the biosensor response was investigated.

In this method review we will give an overview of recent studies which were carried out with the CellDrum technology [2] and underline the added value to already existing standard procedures known from the field of physiology. Herein described CellDrum technology is a system to measure functional mechanical properties of cell monolayers and thin tissue constructs in-vitro. Additionally, the CellDrum enables to elucidate the mechanical response of cells to pharmacological drugs, toxins and vasoactive agents. Due to its highly flexible polymer support, cells can also be mechanically stimulated by steady and cyclic biaxial stretching.}, language = {en} } @inproceedings{Becker2006, author = {Becker, Astrid}, title = {Anlagenmanagement und Aufgaben der DB Netz AG, Bauherrenvertretung und Wirtschaftlichkeit}, year = {2006}, abstract = {In: Alfha.net / Sektion Bauingenieurwesen: 1.
