For this, we present an IP-XACT UML profile that enables UML-based descriptions covering the same information as a corresponding IP-XACT description. This enables the automated generation of IP-XACT component and design descriptions from respective UML models. In particular, it also allows the integration of existing IPs with UML.

In this paper we propose a novel adaptation algorithm for a filter-and-sum beamformer to adjust the coefficients of FIR filters to changing acoustic room impulses, e.g. due to speaker movement. A deterministic and a stochastic gradient ascent algorithm are derived from a constrained optimization problem, which iteratively estimates the eigenvector corresponding to the largest eigenvalue of the cross power spectral density of the microphone signals. The method does not require an explicit estimation of the speaker location. The experimental results show fast adaptation and excellent robustness of the proposed algorithm."}],"status":"public","type":"conference","publication":"IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP 2005)","keyword":["acoustic filter-and-sum beamforming","acoustic room impulses","acoustic signal processing","adaptive principal component analysis","adaptive signal processing","architectural acoustics","constrained optimization problem","cross power spectral density","deterministic algorithm","deterministic algorithms","distant-talking environments","eigenvalues and eigenfunctions","eigenvector","enhanced signal","filter-and-sum beamformer","FIR filter coefficients","FIR filter coefficients","FIR filters","gradient methods","human-machine interfaces","iterative estimation","iterative methods","largest eigenvalue","microphone signals","multichannel signal processing","optimisation","principal component analysis","spectral analysis","stochastic gradient ascent algorithm","stochastic processes"],"language":[{"iso":"eng"}],"_id":"11930","user_id":"44006","department":[{"_id":"54"}]},{"user_id":"55222","department":[{"_id":"151"}],"_id":"9519","language":[{"iso":"eng"}],"keyword":["drives","electromechanical effects","linear motors","ultrasonic motors","car sunroof","car window","electromechanical behavior","high power ultrasonic linear motors","multiple miniaturized motors","positioning tasks","translatory drive","Costs","Electromagnetic forces","Frequency","Laboratories","Manufacturing","Mechatronics","Micromotors","Ultrasonic imaging","Vibrations","Voltage"],"type":"conference","publication":"Ultrasonics Symposium, 2004 IEEE","status":"public","abstract":[{"text":"Several positioning tasks demand translatory drive instead of rotary motion. To achieve drives that are capable e.g. to drive the sunroof of a car or to lift a car's window, multiple miniaturized motors can be combined. But in this case many other questions arise: the electromechanical behavior of the individual motors differs slightly, the motor characteristics are strongly dependent on the driving parameters and the driven load, many applications need some extra power for special cases like overcoming higher forces periodically. Thus, the bundle of motors has to act well organized and controlled to get an optimized drive that is not oversized and costly.","lang":"eng"}],"date_created":"2019-04-29T08:12:06Z","author":[{"first_name":"Tobias","last_name":"Hemsel","full_name":"Hemsel, Tobias","id":"210"},{"full_name":"Mracek, Maik","last_name":"Mracek","first_name":"Maik"},{"first_name":"Jörg","last_name":"Wallaschek","full_name":"Wallaschek, Jörg"},{"first_name":"Piotr","full_name":"Vasiljev, Piotr","last_name":"Vasiljev"}],"volume":2,"date_updated":"2022-01-06T07:04:16Z","doi":"10.1109/ULTSYM.2004.1417988","title":"A novel approach for high power ultrasonic linear motors","issue":"Vol.2","publication_identifier":{"issn":["1051-0117"]},"quality_controlled":"1","citation":{"bibtex":"@inproceedings{Hemsel_Mracek_Wallaschek_Vasiljev_2004, title={A novel approach for high power ultrasonic linear motors}, volume={2}, DOI={<a href=\"https://doi.org/10.1109/ULTSYM.2004.1417988\">10.1109/ULTSYM.2004.1417988</a>}, number={Vol.2}, booktitle={Ultrasonics Symposium, 2004 IEEE}, author={Hemsel, Tobias and Mracek, Maik and Wallaschek, Jörg and Vasiljev, Piotr}, year={2004}, pages={1161–1164} }","short":"T.
