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 ...

Concept for selecting and integrating traceability systems in the continuous improvement process of SMEs
(2019)
Industry 4.0 is characterized by digitization, globalized markets and a growing demand for individualized products. Therefore, the success of manufacturing companies heavily relies on innovative and customer driven products. However, the industrializing phase of such products is often characterized by the occurring of errors originating in a lack of experience. If errors are not detected prior to delivery, costs will increase considerably (e.g. expensive product recalls). Traceability systems can clearly identify the ...

Quality Improvement In Manual Assembly By Software-Based Evaluation Of Human Misconduct
(European Safety and Reliability Association, 2019)
For reaching a level of high quality, production processes must be carried out both, economically and reliably. Despite automation and digitalization, manual assembly operations still constitute a key element for creating efficient production processes. However, in practice, creating robust and efficient manual assembly processes often fails because the occurrence of human errors cannot be quantified prospectively. Therefore, a corresponding procedure has been developed at the institutes of the authors. The module-based ...

Green Luxury: New Divide in Positioning Strategies Needed?
(National University of Political Studies and Public Administration (SNSPA), Faculty of ManagementTritonic, 2017)
A basic and commonly shared implicit definition of luxury is “something superfluous.” Consuming such products and services contradicts the modern paradigm of sustainable consumption. However, luxury vendors are frequently introducing new technologies and better working conditions on a large scale, including natural colors and fair treatment of labor in the fashion industry, as well as fully electric-fueled cars, which Tesla has been producing. Previous research suggests that luxury and sustainability are incompatible. ...

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, ...

Weight reduction of DC/DC converters using controllable inductors
(VDE Verlag, 2019-07)
Controllable inductors can be realized by introducing auxiliary windings into the device that partially saturate the core and allow variation of the inductance value. This can be used to achieve zero-voltage switching in a DC/DC converter over a wide load range while at the same time the weight of the inductor is reduced. In this paper the possible size and weight reduction and the influence on the efficiency is calculated and compared to other solutions. The results are verified in a prototype.

Alexa, Can You Help Us Solve This Problem? How Conversations With Smart Personal Assistant Tutors Increase Task Group Outcomes
(Association for Computing Machinery, 2019)
Despite a growing body of research about the design and use of Smart Personal Assistants, existing work has mainly focused on their use as task support for individual users in rather simple problem scenarios. Less is known about their ability to improve collaboration among multiple users in more complex problem settings. In our study, we directly compare 21 groups who either use a Smart Personal Assistant tutor or a human tutor when solving a problem task. The results indicate that groups interacting with Smart ...

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 ...

Insights into Using IT-Based Peer Feedback to Practice the Students Providing Feedback Skill
(University of Hawaii at Manoa, Hamilton Library, ScholarSpace, 2019)
The skills students need nowadays have changed over the last decades. The required skills are shifting more and more towards higher order thinking skills, such as critical thinking, collaboration and communication. One of the main ways of practicing these skills is through formative feedback, which consists of self-assessment and peer-assessment in our setting.
However, today’s lecturers are facing the challenge that the number of students per lecture is continuously increasing, while the available budget is stagnating. ...
