Parylene-C is used for various biomedical devices because of its high conformity and biocompatibility. However, delamination could occur because of low adhesion between Parylene-C and other materials. For this experiment 4-inch Si-wafers are used. Parylene is deposited by chemical vapour deposition (CVD). Silane A-174 as adhesion promoter is added between Parylene-Parylene layers. The samples are soaked at different duration 1 h, 24 h and 120 h in PBS solution at 37 °C. A peel test is further performed to investigate the adhesion properties of the samples.
Die Firma XYZ benötigt einen neu entwickelten Tragarm für die folgende Generation der Schweißzange. Die Konzeption und Entwicklung des Tragarms findet unter den Gesichtspunkten der Fertigungs- und Montagekosten, sowie Nutzerfreundlichkeit und Design statt. Die Nutzerfreundlichkeit und das Design wird mit Hilfe des aktuellen Tragarms und einer Benchmarkanalyse optimiert. Die Benchmarkanalyse zeigt dabei die unterschiedlichen Ansätze der am Markt existierenden Produkte. Die Bewertung der Konzepte findet mit Hilfe einer Nutzwertanalyse statt. Durch die gewichteten Ergebnisse und Interviews mit den Projektbetreuern können Schwachstellen aufgedeckt und weitere Optimierungsmöglichkeiten gefunden werden. Die Konstruktion wird mit analytischen Methoden zur Berechnung und Auslegung ergänzt. Das Ergebnis ist ein Tragarm, dessen Reichweite und Arbeitsraum den Kundenbedürfnissen entspricht. Unter Berücksichtigung der Tragfähigkeit, Kippsicherheit und Nutzerfreundlichkeit weist der Tragarm ein eigenständiges Design mit Kippmechanismus auf, welches eine stufenlose Anpassung des Arbeitsraumes ermöglicht.

Umsetzung eines Pay-as-you-Live Systems : Konzeptioneller Ansatz für ein eigenständiges PAYL-System

This work gives the theoretical background which is needed to understand what self-assembling monolayers are, how they work, how and for what they can be used. A closer look is taken on the possibility to create an area selective atomic layer deposition process. In a practical experiment the foundation for this process is laid. Therefor a silicon wafer is coated with gold using a evaporation process. The gold samples are exposed to the SAMs solution to grow them. Contact angle measurements as well as Fourier transform Infrared spectroscopy are used to check the existence of SAMs on the gold samples. Also there is investigated if different exposure times make any differences.
Compared to relational databases, graph database systems provide a novel way of processing and analyzing highly interconnected data. Due to their unique properties, graph databases embody an interesting area of research in academic circles. For this reason, this work is fundamentally concerned with examining the state of the industry and current challenges. In this regard, we revisit the basic concepts and highlight the tremendous heterogeneity of available systems using the example of differing path semantics. Based on this insight, we explore algorithmic advancements for graph query processing regarding path finding and worst-case optimal joins. Subsequently, we discuss issues regarding performance and support for graph analytics. Finally, we provide an overview of GQL, a joint standardization effort towards unification of property graph databases.
Wikipedia is the largest free encyclopedia and one of the most popular websites worldwide. Analyzing user activity within this encyclopedic ecosystem represents unique opportunities for academic research and analysis. For this reason, this work is fundamentally concerned with obtaining and processing real-time article edit streams from Wikipedia. In this regard, we leverage the Wikimedia EventStreams API and propose a general-purpose event pipeline allowing for further processing of observed page edits. In the suggested pipeline, events are ingested and transported via an Apache Kafka cluster and inserted into a ClickHouse database for storage and analysis. Finally, we confirm the viability of our design by exploring several exemplary analytical use cases.
