Das Ziel der vorliegenden Arbeit war es, das Potenzial der Blockchain-Technologie für eine dezentrale Energieversorgung aufzuzeigen und abzuwägen. Bislang gibt es nur wenig Forschung und Aufmerksamkeit in diesem Bereich. Die Grundlage für die Ausarbeitung waren praxisnahe Studien und durchgeführte Pilotprojekte von Unternehmen. Die Erkenntnisse zeigen, dass es im Bereich Peer-to-Peer Energiehandel, Labeling und Zertifizierung, Asset Management, Elektromobilität und Netzengpassmanagement zukunftsfähiges Potenzial gibt. Die Blockchain-Technologie bietet eine manipulations-sichere und transparente Dokumentation sowie Automatisierung bestimmter Abläufe. Jedoch müssen dafür regulatorische Rahmenbedingungen angepasst und die Skalierbarkeit gewährleistet werden. Die Bachelorarbeit ist sowohl für Unternehmen im Bereich der energiewirtschaft als auch für private Betreiber von Energieanlagen interessant.

This bachelor thesis deals with framework-agnostic design systems in the environment of micro frontends. The properties of micro frontends and design systems are developed individually, to finally get combined. Important disciplines of this research are in particular cybernetics and system thinking, whereby further properties in the relationships between the stakeholders and the design system are highlighted and defined. In addition, based on the highlighted properties, a practically oriented evaluation is prepared, which demonstratively verifies how framework-agnostic design systems can be realized using Svelte and Tailwind CSS. The insights gained from this work can be used for further considerations in other works within the domain, or similar domains. In particular the cybernetic view of systematic design offers potential for further investigations.

Aufbauend auf einer vorherigen Arbeit, die sich mit der Implementierung einer Komponentezum Auslesen mdizinischer Sensordaten mithilfe eines Arduino und eines Raspberry Pi befasst hat, beschäftigt sich diese Arbeit mit der Visualisierung sowie Auswertung der durch das System gesammelten Daten. Das Ziel dieser Arbeit ist es, über einen Zeitraum von etwa drei Monaten mithilfe der Komponente Daten zu sammeln und diese Daten in einem sinnvollen Kontext visuell darzustellen. Zudem sollen diese Daten mithilfe unterschiedlicher Algorithmen des Maschinellen Lernens ausgewertet werden, um mögliche Muster und Zusammenhänge erkennen zu können. In diesem Kontext konnte die Hypothese aufgestellt werden, dass ein Zusammenhang zwischen der Körpertemperatur und der Sauerstoffsättigung im Blut besteht.

Projects in universities challenge the students in terms of organizing the project progress and coordinating team members. In order to cover the content of the courses in more depth and to prepare the students for their future employment the technical university of cologne (Campus Gummersbach) includes various team projects into its curriculum. Procedure models are helpful ways to structure the project tasks and ensure the communication between team members and stakeholders. The course Projectmanagement presents procedure models such as Waterfall Model, V-Model and Scrum that are mostly used in business context and software engineering. An agile procedure model that is not part of the curriculum is called Design Thinking. It is a suitable approach for student projects as it combines the requirement of an open mindset, a creative, experimental working method and an interdisciplinary toolbox. The objective of this thesis is to design a concept for a procedure model that is customized to students' needs. The growing practice of the design thinking method and other agile procedures within the business world, also increases the importance for students to apply of such models in preperation for professional work. To define the requirements for the recommended procedure model, the first step is to elaborate on the processes and challenges that are currently used in student projects. Then the procedure models Waterfall Model, V-Model and Scrum are presented and evaluated taking into account the students' preferences. Next, Design Thinking is presented structured into three parts: mindset, process and toolbox. The most suitable projects to apply this method are identified in the subsequent analysis. Finally, the most appropriate aspects of the presented procedure models as well as the Design Thinking processes are detected, framed and combined into a new procedure model. The new model is illustrated using a graphical representation and a corresponding explanation. It is clustered into the three fundamental project phases: Planning, Execution and Closure. The Planning phase forms the foundation for a well functioning team and successful project progress. Execution is based on the Design Thinking approach and integrates an iteration-loop formed by the subphases Exploration, Idea Generation, Prototyping, Test and Implementation. The final phase Closure is an incentive for a more creative approach to create final presentations. This model can be developed further and be used for example as a didactic instrument and as a link between the diverse disciplines in interdisciplinary projects across different universities. In this way students learn to apply agile procedures and work in interdisciplinary teams.

This thesis proposes four different Augmented Reality (AR) display techniques that can overcome the problem of uncertain tracking errors. Where most other papers focus on limiting the amount of error that a user tracking system generates, this paper pro-poses visualizations that limit their impact instead. For this, four different display techniques have been developed and evaluated using criteria found in related literate. Two of the four proposed solutions consistently ranked better within these criteria. The first, Bending Words, uses a mix between spatially registered information and turn instructions to achieve that result. The second, WIM, mostly relies on context infor-mation of the building instead.
