In doing so, both the knowledge of the educational sciences and the development of competence self-assessments in the fields of teaching, education, assessment andinnovating are taken into account. The study makes use of the following individual requirements: age, sex, Abitur grade, Bachelor grade, Confession. In order to be able to discuss the re-sults regarding their importance for the professionalization of prospective teachers, the importance of knowledge for professional skills is highlighted, preceded by empirical findings. Subsequently, hypotheses are derived, the plan of the study as well as the test instruments are presented, the results presented and discussed. The results show that the Abitur and Bachelor grades clarify the variance in pedagogical knowledge, that there is a significant development in the competence self-assessments of prospective teachers, and that prospective religious teachers are not different from other students. The discussion takes into account, among other things, the ideas for the devel-opment of professional skills and identifies limitations associated with the study. This is followed by the formula-tion of an outlook. The main aim of the paper is to present representative results of the competence measurement and to examine potential influencing factors on student competence development. A conglomerate of resilient knowledge enriched by this aims to be used in the long term to derive teacher training didactic considerations that support student professionalization.","lang":"eng"}],"user_id":"86519"},{"department":[{"_id":"97"},{"_id":"611"}],"isi":"1","publication_status":"published","publication_identifier":{"issn":["2509-3142"],"eissn":["2509-3150"]},"external_id":{"isi":["000788945100004"]},"title":"Development and validation of a video-based test instrument to measure noticing with regard to processes ofrecognition in inclusive physical education","language":[{"iso":"eng"}],"date_updated":"2023-06-20T19:10:42Z","doi":"10.1007/s12662-022-00807-0","quality_controlled":"1","publisher":"Springer","author":[{"first_name":"Wiebke","full_name":"Langer, Wiebke","last_name":"Langer"},{"id":"72183","last_name":"Bruns","orcid":"https://orcid.org/0000-0002-6604-5864","full_name":"Bruns, Julia","first_name":"Julia"},{"first_name":"Jan","full_name":"Erhorn, Jan","last_name":"Erhorn"}],"keyword":["Physical education teacher education","Competence modelling and","measurement","Inclusive physical education","Video-based items","Noticing"],"publication":"German Journal of Exercise and Sport Research","volume":52,"status":"public","date_created":"2022-12-22T09:22:45Z","article_type":"original","abstract":[{"text":"The construct of noticing is considered to be of crucial importance for professional action of (prospective) physical education (PE) teachers in the context of (inclusive) PE. In order to implement the demands of inclusive PE teaching, noticingwith regard to processes of recognition proves to be particularly significant. Due to the relevance of physicality, the design of recognition relationships that encourage pupils' development results in specific requirements for the selective attention and the theory-based interpretation of processes of recognition and disregard in complex teaching situations. This facet of competence has hardly been studied so far, partly due to the lack of instruments for standardised assessment of this construct. In the context of this paper, the development and validation of a standardised, video vignette-based test instrument for the measurement of noticingwith regard to processes of recognition of prospective PE teachers is presented. The validation focuses on the content of the test and the internal structure of the instrument as well as on correlations with related constructs in terms of content. The results from three consecutive validation studies provide indications of the reliability and validity of the test score interpretation of the instrument ViProQiS_A.

To achieve this, it is necessary to employ an appropriate process or tool design. While this will generally prove successful, it cannot, however, offset stochastic defects with local variations in material properties. Closed-loop process control represents a promising approach for a solution in this context. The state of the art involves using this approach to control geometric parameters such as a length. So far, no research or applications have been conducted with closed-loop control for microstructure and product properties. In the project on which this paper is based, the local martensite content of parts is to be adjusted in a highly precise and reproducible manner. The forming process employed is a special, property-controlled flow-forming process. A model-based controller is thus to generate corresponding correction values for the tool-path geometry and tool-path velocity on the basis of online martensite content measurements. For the controller model, it is planned to use a special process or microstructure (correlation) model. The planned paper not only describes the experimental setup but also presents results of initial experimental investigations for subsequent use in the closed-loop control of α’-martensite content during flow-forming.","lang":"eng"}],"status":"public","date_created":"2021-08-23T13:00:35Z","publisher":"ULiège Library","author":[{"id":"36287","last_name":"Arian","full_name":"Arian, Bahman","first_name":"Bahman"},{"last_name":"Homberg","id":"233","first_name":"Werner","full_name":"Homberg, Werner"},{"last_name":"Riepold","first_name":"Markus","full_name":"Riepold, Markus"},{"id":"552","last_name":"Trächtler","full_name":"Trächtler, Ansgar","first_name":"Ansgar"},{"first_name":"Julian","full_name":"Rozo Vasquez, Julian","last_name":"Rozo Vasquez"},{"last_name":"Walther","first_name":"Frank","full_name":"Walther, Frank"}],"quality_controlled":"1","keyword":["Flow-forming","Spinning","Process Strategy","Martensite Content","Property Control","Micromagnetic Measurement","Metastable Austenitic Stainless Steel"]},{"intvolume":" 88","_id":"46334","date_updated":"2023-10-16T13:07:59Z","doi":"https://doi.org/10.1016/j.asoc.2019.105901","citation":{"ama":"Bossek J, Kerschke P, Trautmann H.

Recently, Ambainis defined the complexity class P^QMA[log], and motivated its study by showing that the physical task of estimating the expectation value of a local observable against the ground state of a local Hamiltonian is P^QMA[log]-complete. In this paper, we continue the study of P^QMA[log], obtaining the following results. The P^QMA[log]-completeness result of Ambainis requires O(log n)-local observ- ables and Hamiltonians. We show that simulating even a single qubit measurement on ground states of 5-local Hamiltonians is P^QMA[log]-complete, resolving an open question of Ambainis. We formalize the complexity theoretic study of estimating two-point correlation functions against ground states, and show that this task is similarly P^QMA[log]-complete. P^QMA[log] is thought of as \"slightly harder\" than QMA. We justify this formally by exploiting the hierarchical voting technique of Beigel, Hemachandra, and Wechsung to show P^QMA[log] \\subseteq PP. This improves the containment QMA \\subseteq PP from Kitaev and Watrous. A central theme of this work is the subtlety involved in the study of oracle classes in which the oracle solves a promise problem. In this vein, we identify a flaw in Ambainis' prior work regarding a P^UQMA[log]-hardness proof for estimating spectral gaps of local Hamiltonians. By introducing a \"query validation\" technique, we build on his prior work to obtain P^UQMA[log]-hardness for estimating spectral gaps under polynomial-time Turing reductions.","lang":"eng"}],"volume":73,"date_created":"2019-03-01T11:25:27Z","status":"public","publication":"12th Conference on the Theory of Quantum Computation, Communication and Cryptography (TQC 2017)","keyword":["Complexity theory","Quantum Merlin Arthur (QMA)","local Hamiltonian","local measurement","spectral gap"],"publisher":"Schloss Dagstuhl - Leibniz-Zentrum fuer Informatik","author":[{"orcid":"0000-0002-9992-3379","full_name":"Gharibian, Sevag","first_name":"Sevag","id":"71541","last_name":"Gharibian"},{"first_name":"Justin","full_name":"Yirka, Justin","last_name":"Yirka"}],"conference":{"name":"12th Conference on the Theory of Quantum Computation, Communication and Cryptography (TQC 2017)","location":"Paris, France"},"_id":"8160","intvolume":" 73","page":"2:1-2:17","citation":{"bibtex":"@inproceedings{Gharibian_Yirka_2018, place={Dagstuhl, Germany}, series={Leibniz International Proceedings in Informatics (LIPIcs)}, title={The Complexity of Simulating Local Measurements on Quantum Systems}, volume={73}, DOI={10.4230/LIPIcs.TQC.2017.2}, booktitle={12th Conference on the Theory of Quantum Computation, Communication and Cryptography (TQC 2017)}, publisher={Schloss Dagstuhl - Leibniz-Zentrum fuer Informatik}, author={Gharibian, Sevag and Yirka, Justin}, editor={Wilde, Mark}, year={2018}, pages={2:1-2:17}, collection={Leibniz International Proceedings in Informatics (LIPIcs)} }","mla":"Gharibian, Sevag, and Justin Yirka. “The Complexity of Simulating Local Measurements on Quantum Systems.” 12th Conference on the Theory of Quantum Computation, Communication and Cryptography (TQC 2017), edited by Mark Wilde, vol. 73, Schloss Dagstuhl - Leibniz-Zentrum fuer Informatik, 2018, p. 2:1-2:17, doi:10.4230/LIPIcs.TQC.2017.2.","chicago":"Gharibian, Sevag, and Justin Yirka. “The Complexity of Simulating Local Measurements on Quantum Systems.” In 12th Conference on the Theory of Quantum Computation, Communication and Cryptography (TQC 2017), edited by Mark Wilde, 73:2:1-2:17.

Gaining insight into the complex interaction between clean speech, noise, and noisy reverberant speech features is essential for any ASR system to be robust against noise and reverberation present in distant microphone input signals. The findings are gathered in a probabilistic formulation of an observation model which may be used in model-based feature compensation schemes. The proposed observation model extends previous models in three major directions: First, the contribution of additive background noise to the observation error is explicitly taken into account. Second, an energy compensation constant is introduced which ensures an unbiased estimate of the reverberant speech features, and, third, a recursive variant of the observation model is developed resulting in reduced computational complexity when used in model-based feature compensation. The experimental section is used to evaluate the accuracy of the model and to describe how its parameters can be determined from test data.","lang":"eng"}],"citation":{"ama":"Leutnant V, Krueger A, Haeb-Umbach R.

Simulations on artificially generated data demonstrate the superiority of the proposed method compared to the Maximum Likelihood technique and to the ordinary MAP approach, whose estimates are corrected by the known statistics of the distortion in a straightforward manner."}],"user_id":"44006","keyword":["Gaussian noise","maximum likelihood estimation","parameter estimation","GMM parameter","Gaussian mixture model","MAP estimation","Map-based estimation","maximum a-posteriori estimation","maximum likelihood technique","noisy observation","sequential estimation framework","white Gaussian noise","Additive noise","Gaussian mixture model","Maximum likelihood estimation","Noise measurement","Gaussian mixture model","Maximum a posteriori estimation","Maximum likelihood estimation"],"publication":"38th International Conference on Acoustics, Speech and Signal Processing (ICASSP 2013)","author":[{"first_name":"Aleksej","full_name":"Chinaev, Aleksej","last_name":"Chinaev"},{"last_name":"Haeb-Umbach","id":"242","first_name":"Reinhold","full_name":"Haeb-Umbach, Reinhold"}],"date_created":"2019-07-12T05:27:20Z","status":"public"},{"author":[{"last_name":"Hoang","first_name":"Manh Kha","full_name":"Hoang, Manh Kha"},{"first_name":"Reinhold","full_name":"Haeb-Umbach, Reinhold","last_name":"Haeb-Umbach","id":"242"}],"keyword":["Gaussian processes","Global Positioning System","convergence","expectation-maximisation algorithm","fingerprint identification","indoor radio","signal classification","wireless LAN","EM algorithm","ML estimation","WiFi indoor positioning","censored Gaussian data classification","clipped data","convergence properties","expectation maximization algorithm","fingerprinting method","maximum likelihood estimation","optimal classification","parameters estimation","portable devices sensitivity","signal strength measurements","wireless LAN positioning systems","Convergence","IEEE 802.11 Standards","Maximum likelihood estimation","Parameter estimation","Position measurement","Training","Indoor positioning","censored data","expectation maximization","signal strength","wireless LAN"],"publication":"38th International Conference on Acoustics, Speech, and Signal Processing (ICASSP 2013)","status":"public","date_created":"2019-07-12T05:28:48Z","abstract":[{"text":"In this paper, we consider the Maximum Likelihood (ML) estimation of the parameters of a GAUSSIAN in the presence of censored, i.e., clipped data. We show that the resulting Expectation Maximization (EM) algorithm delivers virtually biasfree and efficient estimates, and we discuss its convergence properties. We also discuss optimal classification in the presence of censored data. Censored data are frequently encountered in wireless LAN positioning systems based on the fingerprinting method employing signal strength measurements, due to the limited sensitivity of the portable devices. Experiments both on simulated and real-world data demonstrate the effectiveness of the proposed algorithms.","lang":"eng"}],"user_id":"44006","main_file_link":[{"url":"https://groups.uni-paderborn.de/nt/pubs/2013/HoHa2013.pdf","open_access":"1"}],"type":"conference","citation":{"apa":"Hoang, M.

A loosely-coupled error state space Kalman filter, which fuses sensor data of an Inertial Measurement Unit and the output of a Global Positioning System device, is augmented by height information from an altitude measurement unit. This unit consists of a barometric altimeter whose output is fused with topographic map information by a Kalman filter to provide robust information about the current vertical user position. These data replace the less reliable vertical position information provided the GPS device. It is shown that typical barometric errors like thermal divergences and fluctuations in the pressure due to changing weather conditions can be compensated by the topographic map information and the barometric error Kalman filter. The resulting height information is shown not only to be more reliable than height information provided by GPS. It also turns out that it leads to better attitude and thus better overall localization estimation accuracy due to the coupling of spatial orientations via the Direct Cosine Matrix. Results are presented both for artificially generated and field test data, where the user is moving by car."}]}]
