Computing the Poisson-Binomial Distribution for Soccer Match Outcomes
(2024)In soccer analytics, the Poisson-Binomial distribution is used to obtain the probabilities of the possible match scores of a team. This is an important distribution for analysts, because it allows for construction of new descriptive metrics and further meta-analysis. This work outlines the theoretical background of the Poisson-Binomial distribution, hoists it into the context of soccer analytics, while also providing content on the ...Bachelor Thesis -
Exploring the use of WebAssembly for isolating Functions in Dandelion
(2024)Untrusted code execution is the process of running software that cannot be assumed to execute correctly (bug-freedom) or with good intentions (malware-freedom). Today, untrusted code execution is found in various places, from a web-browser safely running websites on a mobile phone, to a large cloud computing provider running customer workloads on managed hardware and infrastructure. From an operating system perspective, we talk about ...Bachelor Thesis -
Experimental Optimization of a Peristaltic Pump Prototype for Pit-Emptying
(2024)The development of efficient, affordable, and mobile pit-emptying techniques is crucial for providing safe sanitation to people in densely populated areas of urban and peri-urban settlements with no access to sewer systems. A functional test stand for a low-cost, manually built peristaltic pump prototype was constructed and used to evaluate the flow rate performance of the prototype and variations thereof. Different tube sizes, tube ...Bachelor Thesis -

Large Language Model's Ability to Reason about Router Configurations
(2024)In this thesis we attempt to utilise large language models (LLMs) to answer networking questions based on router configurations. We establish an approach to ask these questions and evaluate them on the November 2023 preview of OpenAI’s GPT-4 Turbo specifically. Our findings suggest that this LLM performs with varying reliability and requires careful question formulations as well as extensive context to answer correctly.Bachelor Thesis -
Designing a manual press for blackwater dewatering
(2023)Most of sub-Saharan Africa relies on non-sewered sanitation. In the treatment of the ac cumulating blackwater dewatering is a crucial step. Established technologies for dewatering are drying beds or settling tanks. These methods are often land- and time-intensive. Mechani cal dewatering offers a solution to this problem. However commercially available mechanical dewatering presses are often too big in scale, require electricity for ...Bachelor Thesis -
Communication Collectives for the Cerebras Wafer-Scale Engine
(2023)Cerebras Wafer-Scale Engine (WSE) is a powerful architecture used initially for machine learning training but now also for a larger variety of workloads. To achieve the best possible performance on the hardware it is crucial to have efficient reduce and allreduce communication collectives. We therefore provide the first systematic investigation of the reduce operation on the Cerebras WSE using the Cerebras SDK. The provided implementations ...Bachelor Thesis -
Performance Trade-offs Analysis of SmartNIC Architectures
(2023)In-network packet processing utilizing SmartNICs has emerged as a promising method for enhancing the performance of distributed applications. This approach leverages packet-level parallelism and aligns with the in-network computing trend, which involves integrating energy-efficient processing cores with high-speed NICs. By offloading specific data processing tasks to the networking infrastructure instead of relying solely on the Host CPU, ...Bachelor Thesis -
Designing of a communication library for Versal devices using Stream-Based API
(2023)The Versal Adaptive Compute Acceleration Platform is a programmable heterogeneous device that combines general-purpose CPU cores, pro- grammable logic, and specialized AI Engine compute processors in the same System-on-Chip. Versal devices are starting to be shipped in the market, and how to efficiently program and leverage them are still open questions. Max Wierse’s Bachelor Thesis [10] already provides a starting point to reason about ...Bachelor Thesis -
Trusted Firmware for a Research Computer
(2023)Firmware plays a crucial role in the boot process of every computer. However, firmware stacks often suffer from issues related to their size and complexity, typically stemming from years of patchwork to support new platforms or fix bugs. This thesis delves into the realm of firmware by rewriting the initial stage of the firmware stack of the Enzian research computer. The emphasis of this study is on understanding and optimizing the ...Bachelor Thesis
