In this work, a transgenic zebrafish line that expresses the fluorophore dsRed under the endogenous zebrafish cochlin promotor is supposed to be established, using the CRISPR/Cas9 system. dsRed was cloned into a pBluescript vector, followed by the cloning of the cochlin locus into this vector. This bait construct was then supposed to be micro injected into wild type AB zebrafish embryos. The micro injection of Cas9 mRNA, single guide RNA and a bait construct was practiced with the tyrosinase gene, which was disrupted using CRISPR/Cas9.
Die biologische Ammoniumoxidation ist ein zentraler Bestandteil des globalen Stickstoffkreislaufs. Angesichts der extremen Massen Stickstoff anthropogenen Ursprungs in der Umwelt, liegt die Entfernung reaktiven Stickstoffs im Interesse der Umwelt und der öffentlichen Gesundheit. In der folgenden Arbeit werden Bedingungen zur anaeroben Ammoniumoxidation mit Nitrat in einem Anammox-Reaktor untersucht. Dabei wurden 2 Laborreaktoren für eine Zeit von insgesamt 116 Tagen betrieben und beobachtet, die ausschließlich als Elektronendonatoren und Akzeptoren Ammonium und Nitrat enthielten. Zusätzlich wurden Batchkulturen mit Zellen eines Reaktors angezüchtet und auf ihre Gaszusammensetzung abhängig unterschiedlicher Eigenschaften untersucht. Hierbei wurde eine Reihe unterschiedlicher analytischer Quantifizierungsmethoden genutzt und es konnte gezeigt werden, dass ein Abbau unter den Bedingungen stattfindet.
Die aktuelle Forschung zu dieser Reaktion ist spärlich und verleiht der Bachelorarbeit dadurch Relevanz.
The objective of this Bachelor Project is the creation of a tool that should support forensic investigators during IT forensic interventions. It uses Kismet as the base program and adds functionalities to it via the plugin interface. The installation of the plugin shall be explained, how the plugin works, and a recommendation on how to use it. To understand the underlying basics, an introduction about WLAN and Bluetooth is given. The tests that were performed with the new plugin are described as well as their results. It is therefore briefly discussed why the tool is applicable for locating Wi-Fi devices, especially access points, but not Bluetooth devices. Using all this a few ideas on how to improve the tool and what can be researched in this area are provided.
In the field of satellites it is common practice to combine multiple ground stations into one network, to increase communication times with satellites. This work focuses on TIM, which is an international academic colaborative project. Important criteria for this project are elaborated and used to evaluate existing ground station networks. It concludes that there is no appropriate solution availiable for this specific use case and establish a proposed solution. The proposed ground station network software will be elaborated and evaluated.
In this work, we identify similarities between Adversarial Examples and Counterfactual Explanations, extend already stated differences from previous works to other fields of AI such as dimensionality, transferability etc. and try to observe these similarities and differences in different classifier with tabular and image data. We note that this topic is an open discussion and the work here isn’t definite and canbe further extended or modified in the future, if new discoveries found.
The Tutte polynomial is an important tool in graph theory. This paper provides an introduction to the two-variable polynomial using the spanning subgraph and rank-generating polynomials. The equivalency of definitions is shown in detail, as well as evaluations and derivatives. The properties and examples of the polynomial, i.e. the universality, coefficient relations, closed forms and recurrence relations are mentioned. Moreover, the thesis contains the connection between the dichromate and other significant polynomials.
Since its foundation as an application of algebra, coding theory is obtaining a day by day increasing importance. For instance, any communication system needs the concepts of coding theory to function efficiently. In this thesis, reader will find an introductory explanation to linear codes and binary hamming codes including some of the algebraic tools devised in their applications. All the described software applications are verified using SageMath 9.0 using Hochschule Mittweida’s JupyterHub.

The following is a description and outline of the work done at the Cornell Lab of Ornithology developing Nation Feathers VR, a virtual reality game for learning about bird calls and songs. The goal was to develop a game which is intuitive, educational and entertaining. Furthermore, the software needed to be structured in a way that allows for feasible future expansion. This required careful data saving and retrieval. The game gives the player an opportunity to learn and apply that knowledge, all while maintaining a shorter runtime in order to reduce the total time spent in the virtual world. This is meant to prevent any discomfort to the player that may result from extended use of the VR headset.
In this work a second version for the Python implementation of an algorithm called Probabilistic Regulation of Metabolism (PROM) was created and applied to the metabolic model iSynCJ816 for the organism Synechocystis sp. PCC 6803. A crossvalidation was performed to determine the minimal amount of expression data needed to produce meaningful results with the PROM algorithm. The failed reproduction of the results of a method called Integrated and Deduced Regulation of Metabolism (IDREAM) is documented and causes for the failed reproduction are discussed.
