Characterizing the Rheological Behavior of Liquid Silicone Rubber Using a High Pressure Capillary Rheometer
(Society of Plastics Engineers, 2016)
The injection molding process of liquid silicone rubber (LSR) imposes high demands on the injection molding machines and the tools due to the low viscosity of silicone rubber. There is very little data which describes the rheological behavior of LSR and its influencing factors across a range of shear rates.
In this study, the rheological behaviors of different types of LSR were characterized using a high pressure capillary rheometer with an apparent shear rate that ranged from 350 to 4000 1/s. In order to identify ...

Structured Eyetracking-based Requirements Validation with the Help of Virtual Prototypes
(INEGI/Faculdade de Engenharia Universidade do Porto, 2017)
Customer requirements form the basis of every product development project. Incomplete requirements and lack of involvement of customers are the main factors for the failure of a product at the buyer's market (Hull et al. 2011). The Quality Function Deployment (QFD) describes a common method for translating customer requirements into product features. For this purpose, the QFD provides various matrices for the prioritization and quantification of the requirements, through the various phases of the product development. ...

Anforderungsvalidierung unter Nutzung echtzeit simulierter virtueller Prototypen zur Verbesserung der Produktqualität
(FAU University Press, 2017)
Im Rahmen der Anforderungsermittlung werden verschiedene Methoden, wie Befragungs‐ und Beobachtungstechniken eingesetzt, um die bewussten Kundenanforderungen zu erfassen. Verborgene (unbewusste) Kundenanforderungen werden dabei meist nicht berücksichtigt. Aus erhobenen Kundenanforderungen lassen sich z.B. mit einer QFD die späteren Produktmerkmale ableiten. Aufgrund der unscharfen Kundenanforderungslage kommt es bei dem entwickelten Produkt oft zu einer Abweichung von den vom Kunden gewünschten Eigenschaften. Jede ...

Towards A Taxonomy of Text Mining Features
(Association for Information Systems, 2019)
Recently, text mining has received special attention from both researchers and practitioners, since it enables the development of intelligent and automated services. Text mining has been influenced by different disciplines like computer science, statistics, computational linguistics and library and information sciences. However, text mining features that evolved in one particular discipline are often unknown or rarely used in the other disciplines. No scientific feature framework exits which facilitates costly feature ...

Not All Reviews are Equal - a Literature Review on Online Review Helpfulness
(Association for Information Systems, 2019)
The amount of online reviews is growing significantly. Between 2014 and 2017, the number of reviews for TripAdvisor grew by 300% and for Yelp by 208%. However, not all online reviews are equally valuable. Some reviews are perceived to be more helpful or trustworthy then others. Hence, plethora of scholars have investigated the role of online reviews and researched factors and characteristics determining its helpfulness. Nevertheless, mixed findings were found. Consequently, the purpose of our paper is to present a ...

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 ...

El discurso de los santos en Gonzalo de Berceo. Actos de habla y perfiles dialógicos desde la perspectiva de la pragmática histórica. In: Emilio Montero Cartelle
(Meubook, 2012)
Los textos hagiográficos de Gonzalo de Berceo son caracterizados con toda razón como textos marcados en gran medida por la representación mimética de la interacción dialógica. Esta representación dialógica abarca también la caracterización de los propios santos cuyas acciones ejemplares quedan ampliamente reflejadas en escenas de habla y diálogos. En mi análisis se enfocan actos de habla y perfiles dialógicos desde la perspectiva de la pragmática histórica. Las siguientes interpretaciones lingüísticas y filológicas ...

Multicomponent Injection Molding Of Thermoplastics And Liquid Silicone Rubber (LSR) – Either Cured By Heat Or UV Light
(Society of Plastics Engineers, 2016)
For processing thermally curing liquid silicone rubber (LSR) as well as UV light curing LSR for multicompo-nent injection molding with thermoplastics in an compa-rable way a processing center was designed and set into operation.
For the production of the multicomponent specimens a modular tool was designed. In there a thermoplastic plate gets molded on the one side, then gets transferred auto-matically by a robot system and gets overmolded by the silicone on the other side. The complete silicone side of the tool is ...
