TY - THES A1 - Hanafy, Ahmed T1 - API Driven Form Rendering N2 - This master’s thesis investigates the challenges and opportunities associated with dynamic form rendering in user interfaces, specifically in the context of Galeria Karstadt Kaufhof (GKK), a key player in the German retail sector. Collaborating with CODUCT Solutions GmbH, this research aims to enhance GKK’s operational efficiency and user experience in their digital transformation journey, focusing on Project Baldeney, a cloud-native platform that automates content management workflows. The thesis begins by outlining the limitations of traditional, static methods of form rendering, highlighting the implications for development time and error frequency. It identifies the fragmentation in the existing API-driven architectures as a critical issue affecting system reliability and user experience. Against this backdrop, the work proposes a unified, API-driven framework to dynamically render forms for many user actions, such as data input and transactions. The research takes a deep dive into existing systems—particularly Informatica’s Product Information Management (PIM) software and the new software in development Article Workbench to identify user experience issues, inefficiencies, and the complexities involved. Through this examination, it offers a targeted solution to integrate various components of form management, like building, parsing, validation, and rendering, into a cohesive system. The thesis aims to contribute to software development and user experience design substantially, by targeting improved development efficiency, reduced errors, and enhanced system reliability. By achieving these objectives, the research aspires to furnish GKK with a robust solution for dynamic form rendering, thereby enhancing both user satisfaction and system performance in the fast-evolving digital landscape.

Recently, these wetlands are discussed about for their Climate Change mitigation potential by re-wetting efforts. Since most studies on the topic of potential greenhouse gas (GHG) emission reduction in Germany focus on large areas in the North and South of Germany, this study observes a smaller example area of organic soil in Kleve, North-Rhine Westphalia. It is analyzed in terms of suitability for paludiculture as well as for potential savings of GHG and a reduction of the Global Warming Potential (GWP). The study introduces a ranking system that allows an easy estimation of the suitability of fields, based on criteria that assign points from 1 to 4 per criteria. The total for each field is compared with one another. Emission values are based on the GEST-approach, developed by moor scientists in Greifswald, Germany. This study compares current field emissions in Kleve and compares them to theoretical agricultural cultivation scenarios that are simulated and projected onto said fields. The scenarios include the cultivation of Phragmites australis, a grazing system with Bulbalus arnee and the neglection of agriculture supplemented with photovoltaic power harvesting. The research highlights that maintaining high water levels is crucial for significant greenhouse gas emission savings. Water levels of around the soil surface level are assumed to have the highest potential for such savings. Phragmites australis cultivation and the grazing scenario demonstrate the highest potential for savings, reaching up to 2118.56 t CO2-equivalent per hectare annually. Although the findings of this study are promising, it is strongly recommended to update this study with newer findings in the future and to consider production-related emissions that extend the sole on-field emissions.

A critical Assessment of the Ethics of Artificial Intelligence N2 - The literature review at hand addresses the following research question: “Does artificial intelligence and its future development potentially pose a significant threat to individuals’ well-being and humanity’s ethical values?”. For providing answers to the topic at hand, three hypotheses are investigated in detail out of which H0: “Artificial intelligence does pose a significant potential threat to individuals well-being and humanity’s ethical values.” is accepted in accordance with evaluation of findings gathered from 121 sources overall. Threats of artificial intelligence were identified in overall five fields of application, namely medical science, transport industry, potential militarization, surveillance as well as in interaction of artificial intelligence with consumers, for which the natural language processing model ChatGPT was investigated. Regarding medical sciences, threats include potential dehumanization effects through care robots equipped with artificial intelligence. In the transport industry, multiple issues may arise with autonomously operating vehicles while in potential military application of artificial intelligence, research is conducted in multiple countries. Regarding surveillance, artificial intelligence severely facilitates the implementation of social credit systems, as for instance seen in China. Additionally, human nature is embedded in the context of continuous development of artificial intelligence with aim of establishing a first approximation to guidelines of potentially needed limitations of further development of artificial intelligence. It is concluded that, for implementing specific limitations on development of artificial intelligence, more research is needed for identifying the most suitable approach of limiting further development of artificial intelligence.

In this thesis, I present the PlutoChat application that establishes wireless digital communication between two AdalmPluto SDRs in Python programming language. To take advantage of the structure of the Pluto SDR RF chip and handle phase shifts, I introduce the 4/2-QAM quadrature amplitude modulation. For the PlutoChat application, I developed the communication system's components, both on the transmitting and receiving ends, in Python and tested with the data obtained from the Pluto SDR. To address the challenges related to carrier recovery and timing synchronization, adaptive algorithms were used in PlutoChat. This thesis also outlines a communication protocol that involves symbol conversion and frame generation to facilitate the transmission of text messages over the air. To ensure system reliability, I measured the local oscillator performance of the Pluto SDR and tested individual communication blocks of the PlutoChat, including both receiver and transmitter components, using an example text through the Pluto SDR. Having achieved successful transmission and reception, I integrated the communication system blocks in the PlutoChat application. To validate the practical utility of PlutoChat, the end users engaged with the system, sending and receiving text messages via the IPython terminal.
