Changeable Thermal Management for LED-Lighting
(Society of Plastics Engineers, 2015)
Thermal management of LED lights can be arranged by deliberately influencing lighting components conduction capabilities and reducing the thermal contact resistance for various joining processes. The research details the possibilities thereof and shows the thermal contact resistance of plastic and

Development of a Radian Friction Welding Machine Using the Circular Process with Limited Rotational Motion
(Society of Plastics Engineers, 2013)
The processing-technological limitations of components which can not be continuously rotated, either due to their length or marginal protrusions, make the realization of several potential applications using rotation welding unthinkable. The difficulties that arise while generating a high quality weld and are caused by large component tolerances and component warping are known. In order to extend the potential of friction welding, it is necessary to develop a new welding technology. In cooperation with Fischer ...

Interleaved Buck Converter with Coupled Inductors as Auxiliary Bias-Current Source for Controllable Magnetic Devices
(VDE Verlag, 2020-08-26)
This paper presents an Interleaved Buck Converter with Coupled Inductors as a DC-Bias Current Source for Controllable Magnetic Devices, the modular interleaved Buck system supplies a low-ripple current for the auxiliary DC-bias winding of a controllable inductor with different biasing winding disposition in relationship with the main operating flux of the inductor. A 4-phase interleaved Buck converter system was built and inductance measurements where made for different operating current values of the DC-bias and the ...

A Conversational Agent to Improve Response Quality in Course Evaluations
(Association for Computing Machinery, 2020)
Recent advances in Natural Language Processing (NLP) bear the opportunity to design new forms of human-computer interaction with conversational interfaces. We hypothesize that these interfaces can interactively engage students to increase response quality of course evaluations in education compared to the common standard of web surveys. Past research indicates that web surveys come with disadvantages, such as poor response quality caused by inattention, survey fatigue or satisficing behavior. To test if conversational ...

Ergebnisse und Redundanz in der Diskussion um eWOM: Eine kritische Literaturauswertung
(Universität Paderborn, 2014)
Electronic Word-Of-Mouth (eWOM) und Online Rezensionen (OR) werden als einer der Schlüsselfaktoren für erfolgreichen E-Commerce identifiziert. Jedoch sind die beeinflussenden Motivationsfaktoren für das Verfassen sowie das Lesen von OR bis heute gesamtheitlich nur unzureichend untersucht. Die vorliegende Literaturauswertung sammelt die bisherigen Forschungsergebnisse mit dem Ansatz, ein möglichst breites Bild der Motive für eWOM-Aktivitäten zu geben. Das Ergebnis der extensiven Literaturanalyse zeigt, dass für ...

fürchten vs. ängstigen: Thematische Rollen und Ereignisstrukturen psychischer Verben ineinem Modell der Sprachproduktion
(infix-Verlag, 1999)
Die Abbildung außersprachlicher auf sprachsystematische Strukturen stellt für modulare Modelle der Sprachproduktion eine Herausforderung dar: So können scheinbar synonyme Verben ihre thematisch ausgezeichneten Argumente unterschiedlich syntaktisch positionieren: Hans ängstigt Maria oder Maria fürchtet Hans. Theoretisch-linguistische Abhandlungen deuten diese Divergenz als grammatische Eigenheit der Psych-Verben, welche entweder im Sinne einer lexikalischen Stipulation bzw. als Reflex syntaktischer Operationen beschrieben ...

Verbesserung der Produktqualität durch eine frühe Anforderungsvalidierung mithilfe der virtuellen Realität
(Otto-von-Guericke-Universität, Fakultät für Maschinenbau, 2015)
If features meet customer requirements to 100%, one speaks about quality. In the context of the requirement identification various methods are used to generate the conscious customer requirements. Hidden (unconscious) customer requirements are not taken into account. From collected customer requirements, however, the later features can be derived. Therefore, in the developed product it often comes to a deviation from the characteristics required by the customer. Any deviation results in a lower product quality. The ...

Linking entrepreneurial orientation to firm performance in a post-socialist market context: the case of Hungary
(National University of Political Studies and Public Administration (SNSPA), Faculty of ManagementTritonic, 2016)
Entrepreneurial orientation provoked the interest of numerous scholars as well as political and administrative decision-makers. Both start-ups and already established corporate entities are increasingly persecuting new opportunities, products, and business models in order to establish superiority above their competitive environment. The tendencies evince an optimist impact of entrepreneurial orientation on business performance, namely on financial performance. Beyond the aforementioned relationship, there are impulses ...
