Pulsed laser radiation is used to thermoacoustically excite broadband ultrasonic waves in a multi-layered sample, consisting of a metal plate adhesively joined to a polymeric layer using synthetic resin. The resulting signals are received by a purpose-built piezoelectric transducer. Varying the distance between excitation and detection yields spatio-temporal measurement data, from which the dispersive properties of the propagating waves can be inferred using a two-dimensional Fourier transform, assuming the plates to act as coupled waveguides. Coupled multi-layered waveguides show an effect referred to as <jats:italic>mode repulsion</jats:italic>, where the distance between certain modes in the frequency-wavenumber domain is assumed to be a measure of coupling strength. Measurements at different stages of curing of the adhesive layer are performed and evaluated. A comparison of the results shows changes in the dispersive properties, namely an increased modal bandwidth for the fully cured sample as well as an increased modal distance.","lang":"eng"}],"publication":"at - Automatisierungstechnik","type":"journal_article"},{"citation":{"mla":"Iftekhar, Mohammed, et al. “Reference-Less Bang-Bang CDR with Enhanced Frequency Acquisition Range Using Static and Modulated Integral Branch Offset Currents.” <i>The 2021 IEEE BiCMOS and Compound Semiconductor Integrated Circuits and Technology Symposium</i>, 2021, doi:<a href=\"https://doi.org/10.1109/BCICTS50416.2021.9682207\">10.1109/BCICTS50416.2021.9682207</a>.","bibtex":"@inproceedings{Iftekhar_Gudyriev_Scheytt_2021, title={Reference-less Bang-bang CDR with Enhanced Frequency Acquisition Range Using Static and Modulated Integral Branch Offset Currents}, DOI={<a href=\"https://doi.org/10.1109/BCICTS50416.2021.9682207\">10.1109/BCICTS50416.2021.9682207</a>}, booktitle={The 2021 IEEE BiCMOS and Compound Semiconductor Integrated Circuits and Technology Symposium}, author={Iftekhar, Mohammed and Gudyriev, Sergiy and Scheytt, J.

One of these methods is based on transmission measurements of cylindrical polymeric specimens. Here, the experimental setup consists of two transducers, which excite and receive the waveguide modes at the faces of the cylinder. The measurement, as well as a forward model, are used to determine material parameters of the polymeric specimen in an inverse approach.\r\n1-3 piezoelectric composites are used as an active element because they can be approximated by a thickness vibration only. This allows an easy identification of Mason model parameters to characterise the transducers’ vibration behaviour. \r\nHowever, sensitivity analysis shows a high uncertainty in the determination of the mechanical shear parameters due to the uniform excitation. To increase the sensitivity to these shear motions, arbitrary excitations were investigated by means of numerical simulation. \r\nIn order to be able to realise the determined optimal excitation, new transducer prototypes were designed. By subdividing the electrodes of the active element, for example, ring-shaped excitation is feasible. Furthermore, it can be shown that modelling these transducers with a one-dimensional Mason model is sufficient."}],"file":[{"relation":"main_file","success":1,"content_type":"application/octet-stream","access_level":"closed","file_name":"daga","file_id":"25268","file_size":906618,"creator":"dmitrij","date_created":"2021-10-04T07:49:28Z","date_updated":"2021-10-04T07:49:28Z"}],"publication":"Fortschritte der Akustik - DAGA 2021","conference":{"start_date":"2021-08-15","name":"DAGA 2021 - 47.

Neben der Absorption im Fluid treten dabei weitere Effekte (zum Beispiel Beugung oder unvollständige Reflexion) auf, die das akustische Signal schwächen oder anderweitig beeinflussen. Die Entwicklung von Verfahren zur Trennung dieser Effekte von der akustischen Absorption bildet daher einen weiteren Schwerpunkt dieser Arbeit.Abschließend wird die Volumenviskosität aus der gemessenen akustischen Absorption für unterschiedliche Fluide in verschiedenen thermodynamischen Zuständen unter Zuhilfenahme anderer bekannter Fluidkenngrößen bestimmt sowie eine Unsicherheitsbetrachtung durchgeführt.","lang":"ger"},{"lang":"eng","text":"The prerequisite for a complete description of fluid dynamic and acoustic processes is that all properties of the fluid are known.While fluid parameters such as the speed of sound or the shear viscosity are known for many liquids over a wide range of thermodynamic states, only limited measurement data exist for the bulk viscosity.In this thesis, a measurement method for the selective determination of the bulk viscosity of liquids, based on the absorption of ultrasonic waves, is developed and implemented.The focus is on the simulation-driven design of algorithms for processing the measurement signals as well as the analysis and further development of a measurement set-up based on the pulse-echo method.In addition to absorption in the fluid, there are other effects (for example diffraction or incomplete reflection) that weaken or otherwise influence the acoustic signal.Therefore, the development of procedures to separate these effects from acoustic absorption is another focus of this work.The bulk viscosity is determined from the measured acoustic absorption for different fluids in different thermodynamic states.

Modular SSTs which can be interpreted as modular multilevel converters with an isolated DC-DC output stage per module, are designed with redundant modules to increase reliability. Usually, each of the three arms operates independently, and therefore, only a fixed number of faulty modules can be compensated in each arm, even if all modules are operational in the remaining two arms. With the proposed zero-sequence voltage injection, up to 100% more faulty modules can be compensated in an arm by employing the same hardware. In addition, module power imbalances are nearly eliminated by utilizing a fundamental frequency zero-sequence voltage. A dominant 3rd harmonic zero-sequence voltage injection in combination with the 5th, 7th and several higher order harmonics with adaptive (small) amplitudes minimize the required arm voltages at steady-state. For nominal operation or symmetrical faults, the proposed technique is equivalent to the well known Min-Max voltage injection, which already reduces the peak arm voltage by 13.4% compared to a constant star point potential. A statistical analysis proves, that the expected number of tolerable faulty modules of the 1MW SST increases by 12% without the need for additional hardware."}],"status":"public","date_updated":"2022-09-09T12:01:42Z","publisher":"IEEE","date_created":"2022-02-21T16:31:34Z","author":[{"last_name":"Unruh","full_name":"Unruh, Roland","id":"34289","first_name":"Roland"},{"first_name":"Jarren","last_name":"Lange","id":"78801","full_name":"Lange, Jarren"},{"first_name":"Frank","last_name":"Schafmeister","id":"71291","full_name":"Schafmeister, Frank"},{"first_name":"Joachim","orcid":"0000-0002-8480-7295","last_name":"Böcker","id":"66","full_name":"Böcker, Joachim"}],"title":"Adaptive Zero-Sequence Voltage Injection for Modular Solid-State Transformer to Compensate for Asymmetrical Fault Conditions","main_file_link":[{"url":"https://ieeexplore.ieee.org/abstract/document/9570542"}],"doi":"https://doi.org/10.23919/EPE21ECCEEurope50061.2021.9570542","conference":{"location":"Ghent, Belgium","end_date":"2021-09-10","start_date":"2021-09-06","name":"23rd European Conference on Power Electronics and Applications (EPE'21 ECCE Europe)"},"publication_status":"published","publication_identifier":{"isbn":["978-9-0758-1537-5"]},"year":"2021","citation":{"apa":"Unruh, R., Lange, J., Schafmeister, F., &#38; Böcker, J.

A\r\nsensor takes measurements of the system output and forwards its dynamic state\r\nestimates to a remote controller over a packet-dropping link. The controller\r\ndetermines the optimal control law for the process using the estimates it\r\nreceives. An attacker aims at degrading the control performance by increasing\r\nthe packet-dropout rate with a DoS attack towards the sensor-controller\r\nchannel. We assume both the controller and the attacker are rational in a\r\ngame-theoretic sense and establish a partially observable stochastic game to\r\nderive the optimal joint design of scheduling and control. Using dynamic\r\nprogramming we prove that the control and scheduling policies can be designed\r\nseparately without sacrificing optimality, making the problem equivalent to a\r\ncomplete information game. We employ Nash Q-learning to solve the problem and\r\nprove that the solution is guaranteed to constitute an $\\epsilon$-Nash\r\nequilibrium. Numerical examples are provided to illustrate the tradeoffs\r\nbetween control performance and communication cost.","lang":"eng"}],"type":"preprint","publication":"arXiv:2103.05893","language":[{"iso":"eng"}],"user_id":"158","department":[{"_id":"57"}],"_id":"35588","external_id":{"arxiv":["2103.05893"]}}]
