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 ...

The lexicalization of complex constructions: an analysis of adjective-noun combinations
(Pasithee : Open Access Electronic Publications; Library & Information Center - University of Patras, 2016)
The current paper discusses the lexicalization of complex constructions composed of an adjective and a noun. It is argued that compounds/compound-like constructions are more prone to become lexicalized than phrases/phrase-like constructions. The relationship between lexicalization and the cognitive process of memorization represents a key point of our analysis. We report evidence from psycholinguistic studies contrasting compounds/compound-like constructions to phrases/phrase-like constructions either within a single ...

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 ...

Beyond Ritz-Galerkin: Finite element approximations on a manifold in the configuration space [Abstract]
(Institute of Structural Analysis and Antiseismic Research, School of Civil Engineering, National Technical University of Athens (NTUA), 2016)
An extension of the Ritz-Galerkin method, based on finding approximations on a finite-dimensional manifold of functions (i.e., not a linear subspace) in the infinite-dimensional exact configuration space, will be presented. This new approach is particularly efficient in computing geometrically exact solutions for problems involving large rotations.

The acceptance of mobile payments in the German retail market
(National University of Political Studies and Public Administration (SNSPA), Faculty of ManagementTritonic, 2016)
The acceptance of mobile payments is one of the research challenges of high strategic relevance in retailing. Most of the previous studies of mobile payment field focus on consumers’ opinions, expectations and concerns to assess their acceptance of mobile payment systems. The financial transactions’ complementing party – the merchants – who also needed to accept and, therefore, to implement mobile payment technologies is considered in this study. The purpose of this study is to enhance an existing research framework, ...

Coupling atomistic models with continuous finite beam elements [Abstract]
(Institute of Structural Analysis and Antiseismic Research, School of Civil Engineering, National Technical University of Athens (NTUA), 2016)
Concurrent simulations of atomistic (discrete) and continuum models are one key to perform static calculations of large atomistic structures. Occurring ghost forces at the interfaces between discrete (atomistic) and continuous regions are a major challenge for the definition of such interfaces. The so called virtual projection method [1] is a class of force-based a/c schemes which reduce (or even avoid) ghost forces. This class of coupling schemes is able to deal with atomistic models consisting of bonded, multi-body ...

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 ...

Joining Investigations of Polymer-Metal-Hybrids for Permanantly Non-Leaking Applications
(Society of Plastics Engineers, 2016)
The demand for light-weight construction and economic efficiency has led to the development of light-weight construction strategies, i.e., multi-material design, in many areas of industry. Here, the property profiles of the composite partners are utilized synergetically. Plastic-metal hybrid composites possess a large amount of potential in this regard owing to the weight reduction that can be achieved in the composite and the simultaneous enhancement of the mechanical properties.
Hybrid components have already ...

Development of a Flexible Polymer Joining Center Capable of Performing Multiple Joining Processes Using Different Methods in a Single Cycle
(Society of Plastics Engineers, 2016)
Goal of this research and innovation project is the implementation of a flexible polymer joining center as a prototype machine integrating different friction welding methods. This prototype joining cell combines (a) flexibility by being capable of performing joining processes in any order in a single flow with (b) modularity by integrating unified interfaces for exchanging joining modules, and (c) scalability by offering a wide range of setups for smaller to larger work pieces. Corresponding interfaces to up- and ...
