How much does it burn? Profiling the energy model of a Tofino switch
(2023)The ICT sector, in which the Internet plays a significant role, is growing rapidly, and along with it, the amount of power required to maintain its infrastructure. This includes powering various devices such as routers and switches, but currently, we lack sufficient knowledge about their power profile. This thesis brings a piece to the puzzle by power profiling the WEDGE100BF32Q, a commercial, programmable switch intended for data centers. ...Student Paper -
Modeling Choice in Co-Design
(2021)This report describes a method for modeling free and forced choice within Co-Design. In a free choice among a set, one has control over which option is selected, while in a forced choice one does not. Given a preorder P describing resources or functionalities, a free choice among a subset of P acts like a meet. Dually, a forced choice acts like a join. Moreover, the two types of choice distribute over one another. Based on this, we construct ...Student Paper -
The Shadow of a Rotating Black Hole
(2021)The aim of this work is to provide an introduction to the field of shadows of rotating Kerr black holes. We review the mathematics of light propagation in Kerr spacetime and derive the equations describing the edge of a Kerr black hole shadow in the sky of a distant observer. We also discuss recent research concerning the possibility of determining the spin parameter a and the inclination angle θ_O of the observer from direct observations ...Student Paper -
Proboscis search & rescue. Worm-like Softrobot for Search and Rescue Missions
(2018)Even though earthquakes are older than mankind, rescue equipment is still quite rudimentary. Currently, buried victims can be located with dogs or drones, but to reach them, large amounts of debris and other obstacles have to be removed carefully. This can take several days as heavy machinery and a lot of manpower is required. The goal of Focus Project Proboscis is to shortcut the rescue process and work on a physical solution to ...Student Paper -
Space Geodesy Project Report
(2023)This research aimed to address the challenge of improving the reliability of the Water- GAP Global Hydrology Model (WGHM) using the Gravity Recovery and Climate Experiment (GRACE) satellite data as a benchmark. Our problem was defined by the need to align WGHM Total Water Storage Anomaly (TWSA) data more closely with the reliable GRACE satellite measurements to enhance the simulation quality. We developed a method employing a Gaussian ...Student Paper -
CEU (Centros Educacionair Unificados) : Translating socio-democratic values through the formation of community integrated educational spaces
(2017)The CEUs, or Unified Education Centres (Centros de Educacao Unificados) are public facilities conceived as local centres of urban life, located in the peripheral and disenfranchised areas of São Paulo, Brazil. The facilities are intended for education, culture and sport and are for both school students and the surrounding community. The centres were developed by the Municipal Buildings Department (EDIF), and designed by the architects ...Student Paper -
Heimliche Seelenverwandte?
(2023)Das Exposé geht der Frage nach, ob und wie sich das in jüngerer Zeit etablierte Politikfeld Baukultur als Konzept mit ganzheitlichem Anspruch für eine vermehrt qualitative Diskussion und Weiterentwicklung der Raumplanung fruchtbar machen lässt. Eine Differenzierung der Beziehung von Raumplanung und Baukultur in drei Schritten kommt zum Schluss, dass beide Politikfelder dem gemeinsamen Ziel einer nachhaltigen Gestaltung des Lebensraums ...Student Paper -
Ersatzneubauten bei Siedlungen der Nachkriegszeit: Verdichtung oder Verdrängung?
(2024)Günstiger Wohnraum in urbanen Gemeinden wird rar. In den betroffenen Regionen führt das zu sozialer Segregation. Insbesondere vulnerable Bevölkerungsgruppen müssen zen- trumsnahe Gebiete verlassen. Neben Wohnungen in genossenschaftlichem und staatlichem Eigentum, ist insbesondere wenig und unsanierter Wohnraum günstig. Das trifft oft auf den Siedlungsbestand der Nachkriegsjahre (Baujahr 1945-1960) zu. Diese Arbeit zeigt auf, wo und wie ...Student Paper -
Multi-Karma Economies
(2024)Limited public resources include fast lanes on highways, parking spots at high-interest locations near a city center, and access to EV charging stations during peak hours. Elokda et al. proposed karma economies as a non-monetary approach to an effective allocation of such resources and demonstrated an improvement of discomfort cost for all participants with respect to classic solutions. However, so far only single-resource economies have ...Student Paper -
