Fabrication and Investigation of Diamond Membranes for Photonic Nanostructures
(2023)
Due to its exceptional physical and chemical characteristics, diamond in a form of thin membranes is a particularly promising material for the fabrication of high-quality photonic devices. Especially for envisioned applications in quantum information technologies and communication, diamond gained, as a host material, an ever-increasing scientific interest based on remarkable properties of different color centers in its crystal lattice, e.g. nitrogen-vacancy centers, serving as single-photon emitters. As a high index ...

Verfassungsrechtliche Analyse der Modernisierung des Besteuerungsverfahrens
(2023)
Große Teile des „Gesetz[es] zur Modernisierung des Besteuerungsverfahrens“ traten am 1. Januar 2017 in Kraft. Mit diesem Gesetz wollte der Gesetzgeber eine Zeitenwende im steuerlichen Verfahrensrecht einläuten, indem er die seit langem in der Verwaltungspraxis verwendete Möglichkeit, Verwaltungsakte ausschließlich automationsgestützt zu erlassen, erstmals gesetzlich regelte. Kernstück dieses Gesetzgebungspaketes ist die erstmalige gesetzliche Regelung eines Risikomanagementsystems zur Prüfung von Steuererklärungen.

Characterisation of Cold Asphalt Mixtures with the Addition of Active Fillers
(2023)
Climate change, the limited availability of natural resources, and energy crises are putting pressure on the global societies? to employ low-energy and low-emission technologies for road pavement construction. Cold Recycled Materials (CRM) is an efficient and low-impact solution. CRM with Bituminous Emulsion (CRM-BE) is one of the most common types of CRM. CRM-BEs are created at ambient temperature by combining a high amount of Reclaimed Asphalt (RA) with Bitumen Emulsion (BE). BE used in CRM is typically composed ...

Capital Accumulation, Sector Productivity, and Economic Growth
(2023)
This dissertation is motivated by the research results of Benigno and Fornaro (2014). Benigno and Fornaro (2014) research, how low interest rates impact the productivity of economies.
This dissertation implements extensions of the Benigno and Fornaro (2014) model, that particularly address the capital accumulation, the production functions, and the technology accumulation. In doing so, this dissertation shows that some of the Benigno und Fornaro (2014) research results require specific assumptions, to qualitatively ...

Industry 4.0-driven additive manufacturing for operations in the circular economy
(2023-06)
This dissertation focuses on exploring how key elements of Industry 4.0 (I4.0), such as additive manufacturing (AM) and quantitative techniques/simulation, instigate the operations of an organisation towards the circular economy (CE). AM represents the technological foundation of future manufacturing which efficiently utilises materials avoiding unnecessary waste. Further, it could positively impact the transition towards CE by addressing issues related to the operations and supply chains while positively influencing ...

Die Beschreibung professioneller Handlungskompetenz von (angehenden) Lehrkräften in schulischen Praxisphasen
(2023)
Die Dissertation untersucht die subjektive Beschreibung professioneller Handlungskompetenz von (angehenden) Lehrkräften in schulischen Praxisphasen und ist in vier Teilkapitel gegliedert.
Der theoretische Rahmen bildet den ersten Teil der Arbeit und befasst sich mit der Frage, was die professionelle Handlungskompetenz von Lehrkräften ist, wie sie erfasst werden kann und welche theoretische Einordnung vorzunehmen ist. Drei Abschnitte geben Aufschluss über das Modell der professionellen Handlungskompetenz von ...

Geospatial crop yield modeling for climate change risk transfer, impact assessment, and adaptation strategies
(2023)
Changing climate and weather patterns increase the pressure on food production systems worldwide, significantly impacting livelihoods and economies at various scales. Understanding and adapting/mitigating climate change are essential to cope with the adverse effects of climate change. Biophysical crop modeling offers a unique way to assess the pros and cons of different adaptation strategies because they integrate physical and biological principles to simulate the use and allocation of captured resources mechanistically. ...

Analysis of a Coupled Fluid-Elastic Interaction Problem
(2023-01)
In this thesis, a non-linear system of partial differential equations is studied, describing the motions of an elastic structure which is immersed into an incompressible viscous fluid. The displacement of the elastic structure is modelled by a Lamé system and the fluid velocity as well as the fluid pressure are described by the Navier-Stokes equations. The structure and the fluid are coupled via two boundary conditions at the interface which correspond to continuity of velocities and forces. As the elasticity is ...

Nutrition transition in Kyrgyzstan: Understanding the triple burden of malnutrition and the importance of dietary quality
(2023)
Nutrition transition, including changes in lifestyle and diet, has been taking place globally. Malnutrition is a serious public health issue responsible for the considerable portion of noncommunicable diseases (NCDs). Currently, little knowledge about nutrition transition and its relation to malnutrition exists in low and middle-income countries. Kyrgyzstan undergoes a nutrition transition with health and diet implications, especially to women. Kyrgyzstan is believed to be at the end of the ‘receding famine’ stage ...
