Investigation of the adhesive strength in a combined compaction and back-injection process to produce back-injected self-reinforced composites (SRCs)
(2022-03-08)
This publication investigates the adhesion between an injection molded component and a self-reinforced composite (SRC) produced in a combined compaction and back-injection process to produce back-injected self-reinforced composites. To study the influence of the process, the parameters barrel temperature, time of injection, and tool temperature were varied. In addition, samples were taken at different positions along the flow path. In light of the orthotropic material behavior of SRCs, investigations were conducted ...

Patterns of Practice - Interdisciplinary Negotiation of Cultural Complexity through Practice-Based Methods in Informatics
(2022)
Following the principle of knowing through making, this thesis discusses development and application of a practice-based methodology for construction of digital artefacts within
cultural contexts. It addresses the epistemological diversity and complexity inhering within interdisciplinary projects, suggesting methodological devices able to navigate the variegated disciplinary landscape present within respective development projects. The conceptual pair complexity/complication acts as theoretical point of reference ...

Textile Waste Becomes Plastic Composites
(2023-09)
Every year, large quantities of textiles end up in landfills or in thermal recycling. However, some of this waste could also serve as raw materials for composite materials. Left-over cotton fibers of the textile industry, for example, are suitable as reinforcing fibers that enhance the mechanical properties of bio-based plastics. By using such waste streams, materials can be reinforced in a cost-effective and bio-based way in the future.

Analysis on Successful Project Completion in Reward-based Crowdfunding
(2023-10)
Project creators often encounter difficulties when trying to secure funding. This is primarily because traditional investors view projects as lacking equity, not attractive enough and carrying high risks. However, with the advent of Web 2.0 crowdfunding has emerged as an alternative financing option in recent years. While crowdfunding continues to foster innovation and creativity the success rate of reward-based crowdfunding campaigns is often below 50%. Consequently, project creators are actively seeking solutions ...

Ordoliberalism Out of Order? The Fragile Constitutionality of Greek Austerity (Part Two)
(2020-06)
This is the second part of a two-part post. The first part, available here, considered the historical background of the concept of constitutional order and its relation to the ordoliberal project. Judicial independence was examined in parallel with central bank independence, with each understood as a means of insulating policy from social and democratic pressures and also as a means of enacting and maintaining fiscal discipline and market-conforming order. It also included some preliminary observations on the relation ...

Ordoliberalism Out of Order? The Fragile Constitutionality of Greek Austerity (Part One)
(2020-05)
The architecture of the European Monetary Union (EMU) has often been understood to be built on a fundamentally ordoliberal framework. [1] The precise characteristics of what constitutes an ordoliberal framework are often not clarified, and they have been widely debated in contemporary scholarship. But a crucial characteristic of ordoliberalism, and one that has received comparatively little attention, concerns the importance of grounding economic policy in a “constitutional order”: ordoliberal political economy insists ...

The Implications of Feedback Frequency for Employee Creativity
(2022)
Managers are still floundering when they have to decide on the optimal level of feedback frequency; either when they consider themselves as a source of feedback, but also when they shape the feedback environment of their employees, e.g., by allowing more (or less) frequent customer feedback. Furthermore, given that feedback is a time-consuming task, managers might be reluctant to provide feedback frequently, foregoing a potentially powerful lever for increasing employee creativity. Ultimately, clarifying the ambiguities ...

Fast parallel quasi-static time series simulator for active distribution grid operation with pandapower
(IET, 2021)
The increasing penetration from intermittent renewable distributed energy resources in distribution grid brings along challenges in grid operation and planning. To evaluate the impact on the grid voltage profile, grid losses, and discrete actions from assets (e.g. transformer tap changes), quasi-static simulation is an appropriate method. Quasi-static time series and Monte-Carlo simulation requires a tremendous number of power flow calculations (PFCs), which can be significantly accelerated with a parallel High-Performance ...

Holzdesign trifft Kunststofftechnik
(2022)
Werkstoffverbunde aus Holzgeweben in einer thermoplastischen Matrix verbinden die Idee des textilen Holzbaus mit der Faserverbundtechnologie. In einem Projekt werden Fassadenelemente aus solchen Wood Textile Composites hergestellt. Dabei spielt neben den mechanischen Anforderungen auch die gestalterische Seite und die Akzeptanz der zukünftigen Nutzer eine wichtige Rolle.
