Particularly in the automotive sector, lightweight design principles continue to prosper rapidly. As a result, adjusted materials for different applications were developed. Due to the formation of intermetallic phases, most multi-material mixes cannot be welded and require adapted joining technologies. Mechanical joining technologies such as self-piercing riveting and mechanical clinching have proven effective methods of joining lightweight materials like aluminium and ductile steels. New high-strength steels are increasingly used in crash-sections, where limited deformation under impact load is required. These hot stamped steels have a very low elongation at break and therefore a low formability. Currently there is no joining by forming technology without pre-punching available using these grades of steels on die-side. The newly developed shear-clinching process is one possible method of joining this kind of material without additional elements. The fundamental idea of shear-clinching is a single-stage process in which pre-punching of the die-side material is performed by indirect shear-cutting and subsequent forming of the upper layer into this hole. This would immensely enlarge the application segment of mechanical clinching even if hot stamped steels are positioned on die-side. Fundamental studies are required to ensure process reliability and it is necessary to break down the joining process into fragments, like pre-punching and clinching with pre-punched sheet, and superpose them to form the combined procedure shear-clinching. This paper presents a detailed investigation of the sub-process clinching with pre-hole.","lang":"eng"}],"title":"Basic Investigations of Non-Pre-Punched Joining by Forming of Aluminium Alloy and High Strength Steel with Shear-Clinching Technology","page":"1413-1420","volume":"611-612","type":"journal_article","publication":"Key Engineering Materials"},{"date_created":"2018-09-19T08:22:51Z","publisher":"EARLI European Association for Research on Learning and Instruction","type":"conference","year":"2013","status":"public","_id":"4478","date_updated":"2022-01-06T07:01:06Z","conference":{"end_date":"2013-08-31","name":"15th Biennial EARLI Conference","location":"München ","start_date":"2013-08-27"},"title":"On the assessment of attitudes towards the study process and the university: Attitudes towards the Study Environment Questionnaire (ASEQ)","author":[{"last_name":"Brahm","full_name":"Brahm, Taiga","first_name":"Taiga"},{"orcid":" https://orcid.org/0000-0001-9262-5646","last_name":"Jenert","id":"71994","full_name":"Jenert, Tobias","first_name":"Tobias"},{"full_name":"Euler, Dieter","first_name":"Dieter","last_name":"Euler"}],"extern":"1","abstract":[{"lang":"eng","text":"The purpose of the research was to develop and validate an instrument for the assessment of attitudes towards the study environment in higher education contexts. The questionnaire is designed to measure students' attitudes towards two particular objects: the university (or Higher Education Institution) and the process of studying. Five studies at two different universities were conducted to develop and validate the Attitudes towards the Study Environment Questionnaire (ASEQ). In total, 1640 students filled in the questionnaire. Reliability tests and exploratory factor analysis as well as confirmatory factor analysis showed satisfactory psychometric characteristics of the ASEQ. Each part of the questionnaire is internally consistent and construct validity of the scales is supported by correlations with other constructs as assumed by current theories: Positive attitudinal constructs (normative behavior, autonomy, joy, self-efficacy, and task value) are positively related to intrinsic motivation and the expected study performance while anxiety is negatively related to these constructs. \r\nSince attitudes towards the study situation are connected to student engagement and motivation, the study contributes to the theory of student learning by providing a validated instrument to assess attitudes. Thus, the ASEQ can support further research on student performance and development by providing an instrument for the hitherto neglected but nonetheless extremely relevant domain of attitudes. Also, the questionnaire can be used as a diagnostic instrument for higher education faculty and administration to trace students' attitudinal development over time - a factor of prime importance for student socialization during the introductory phase of studying."}],"citation":{"short":"T.

Zur Beantwortung dieser Fragen wurde über das erste Studienjahr hinweg eine Interviewserie mit 13 Studierenden durchgeführt.

While these steps are classically assumed to involve stiction and sliding, the motors can also operate in ``slip--slip'' mode without any phase of static friction. This contribution provides a systematic investigation and performance comparison of different stick--slip and slip--slip modes of operation. Different criteria for comparing the motional performance of inertia motors are defined: Steady state velocity, smoothness of motion, and start-up time. Using the example of a translational inertia motor excited by an ideal displacement signal, it is found that the maximum velocity reachable in stick--slip operation is limited principally, while continuous slip--slip operation allows very high velocities. For the investigated driving signals, the motor velocity is proportional to the square root of the actuator stroke. The motor performance with these ideal signals defines an upper boundary for the performance of real motors.","lang":"eng"}],"title":"Stick-slip and slip-slip operation of piezoelectric inertia drives - Part I: Ideal Excitation.","user_id":"55222","keyword":["Inertia motor","Stick--slip drive","Mode of operation","Performance indicator","Velocity maximization","Actuator stroke"]},{"page":"6827-6831","_id":"11716","date_updated":"2022-01-06T06:51:07Z","publication":"Acoustics, Speech and Signal Processing (ICASSP), 2013 IEEE International Conference on","date_created":"2019-07-12T05:26:53Z","status":"public","publication_identifier":{"issn":["1520-6149"]},"year":"2013","type":"conference","language":[{"iso":"eng"}],"user_id":"44006","keyword":["Bayes methods","Gaussian processes","convolution","decision theory","decoding","noise","reverberation","speech coding","speech recognition","Bayesian decision rule","GMM","Gaussian mixture models","additive noise scenarios","automatic speech recognition systems","convolutive noise scenarios","decoding approach","mathematical framework","reverberant environments","significance decoding","speech feature estimation","uncertainty-of-observation techniques","Hidden Markov models","Maximum likelihood decoding","Noise","Speech","Speech recognition","Uncertainty","Uncertainty-of-observation","modified imputation","noise robust speech recognition","significance decoding","uncertainty decoding"],"citation":{"short":"A.H.

We use a sample of 1,949 small private firms operating in the period 2006-2010 with optional financial statement audit. High quality data allows us to construct a more precise interest rate measure than existing studies employ. After controlling for obvious sources of demand for voluntary audits (ownership complexity, subsidiary status, bank relations), we find a robust central result that voluntary audits increase rather than decrease the cost of debt financing, contrary to several existing studies. This finding indicates that voluntary audits are generally treated as “adopting a label” and penalised by creditors, regardless of the perceived auditor quality as a result of the lemon problem in the audit market. Even Big-4 audits increase the cost of debt, likely as a result due to the lemon problem in the audit market, although the increase is smaller than for non-Big-4 audits. The results are sensitive to the estimation method used (OLS, Heckman’s two-step, PSM) and (sub-)sample selection. We show that disregarding the underlying assumptions of these estimation methods may lead to incorrect inferences. Additional analyses show that audited firms’ reported earnings are less informative about future operating performance than earnings of their unaudited counterparts. Our results also indicate that results are sensitive to cost of debt definition and this might have affected the results reported in the existing literature.","lang":"eng"}],"extern":"1","author":[{"full_name":"Kosi, Urska","first_name":"Urska","last_name":"Kosi","id":"54068"},{"last_name":"Koren","full_name":"Koren, Jerney","first_name":"Jerney"},{"full_name":"Valentincic, Aljosa","first_name":"Aljosa","last_name":"Valentincic"}],"title":"Does Financial Statement Audit Reduce the Cost of Debt of Private Firms?","conference":{"start_date":"2013-05-02","location":"Paris, France","name":"36th Annual Congress of European Accounting Association","end_date":"2013-05-05"}},{"intvolume":"        14","author":[{"last_name":"Nomikou","first_name":"Iris","full_name":"Nomikou, Iris"},{"last_name":"Rohlfing","id":"50352","first_name":"Katharina","full_name":"Rohlfing, Katharina"},{"last_name":"Szufnarowska","full_name":"Szufnarowska, Joanna","first_name":"Joanna"}],"department":[{"_id":"749"}],"citation":{"mla":"Nomikou, Iris, et al. “Educating Attention: Recruiting, Maintaining, and Framing Eye Contact in Early Natural Mother-Infant Interactions.” <i>Interaction Studies</i>, vol. 14, no. 2, John Benjamins Publishing Company, 2013, pp. 240–67, doi:<a href=\"https://doi.org/10.1075/is.14.2.05nom\">10.1075/is.14.2.05nom</a>.","bibtex":"@article{Nomikou_Rohlfing_Szufnarowska_2013, title={Educating attention: recruiting, maintaining, and framing eye contact in early natural mother-infant interactions}, volume={14}, DOI={<a href=\"https://doi.org/10.1075/is.14.2.05nom\">10.1075/is.14.2.05nom</a>}, number={2}, journal={Interaction Studies}, publisher={John Benjamins Publishing Company}, author={Nomikou, Iris and Rohlfing, Katharina and Szufnarowska, Joanna}, year={2013}, pages={240–267} }","short":"I.

Applying a microanalytical approach focusing on the sequential organization of interaction, we explored how the mother draws the infant’s attention to herself and how she tries to maintain attention when the infant is looking at her. Results showed that eye contact is reinforced by specific infant-directed practices: interrogatives and conversational openings, multimodal stimulation, repetition, and imitation.

Until now, contact center agents still read these messages and forward them to the persons in charge of customer’s in the company. But with the introduction of Web 2.0 and social networking clients are more likely to communicate with the companies via Facebook and Twitter instead of filling data in contact forms or sending e-mail requests. In order to maintain an active communication with international clients via social media, the multilingual consumer contacts have to be categorized and then automatically assigned to the corresponding business processes (e.g. technicalservice, shipping, marketing, and accounting). This allows the company to follow general trends in customer opinions on the Internet, but also record two-sided communication for customer relationship management.","lang":"eng"}],"main_file_link":[{"url":"http://exmaralda.org/gscl2011/downloads/AZM96.pdf","open_access":"1"}],"keyword":["Classification of Multilingual Customer Contacts","Contact Center Application Support","Social Media Business Integration"],"oa":"1","user_id":"42496","publisher":"University of Hamburg","date_created":"2018-01-29T15:48:34Z","status":"public","language":[{"iso":"eng"}],"year":"2011","publication_identifier":{"issn":["0176-599X"]},"_id":"1122","date_updated":"2022-01-06T06:50:58Z","author":[{"orcid":"0000-0002-8180-5606","full_name":"Geierhos, Michaela","first_name":"Michaela","id":"42496","last_name":"Geierhos"},{"last_name":"Lee","first_name":"Yeong Su","full_name":"Lee, Yeong Su"},{"last_name":"Bargel","first_name":"Matthias","full_name":"Bargel, Matthias"}],"editor":[{"last_name":"Hedeland","full_name":"Hedeland, Hanna","first_name":"Hanna"},{"last_name":"Schmidt","first_name":"Thomas","full_name":"Schmidt, Thomas"},{"first_name":"Kai","full_name":"Wörner, Kai","last_name":"Wörner"}],"conference":{"end_date":"2011-09-30","name":"Conference of the German Society for Computational Linguistics and Language Technology (GSCL 2011)","start_date":"2011-09-28","location":"Hamburg, Germany"},"intvolume":"        96","place":"Hamburg, Germany","publication_status":"published","citation":{"bibtex":"@inproceedings{Geierhos_Lee_Bargel_2011, place={Hamburg, Germany}, series={Arbeiten zur Mehrsprachigkeit - Folge B}, title={Processing Multilingual Customer Contacts via Social Media}, volume={96}, booktitle={Multilingual Resources, Multilingual Applications: Proceedings of the Conference of the German Society for Computational Linguistics and Language Technology (GSCL) 2011}, publisher={University of Hamburg}, author={Geierhos, Michaela and Lee, Yeong Su and Bargel, Matthias}, editor={Hedeland, Hanna and Schmidt, Thomas and Wörner, KaiEditors}, year={2011}, pages={219–222}, collection={Arbeiten zur Mehrsprachigkeit - Folge B} }","mla":"Geierhos, Michaela, et al. “Processing Multilingual Customer Contacts via Social Media.” <i>Multilingual Resources, Multilingual Applications: Proceedings of the Conference of the German Society for Computational Linguistics and Language Technology (GSCL) 2011</i>, edited by Hanna Hedeland et al., vol. 96, University of Hamburg, 2011, pp. 219–22.","short":"M.
