Producing building blocks for data analytics
(2019)The ever increasing diversity of data analytics and AI applications has had a tremendous impact on the number of tools that were developed during the past few years. The developers of these tools usually do not spend a lot of time thinking which are the building blocks that lie in their core. As a result, they sometimes have to produce many slightly different versions of the same code fragments. Instead, they could reduce their implementation ...Master Thesis -
Applying Machine Learning Methods to the Assessment of Tropical Cyclone Impacts
(2019)Tropical cyclones are among the most disastrous natural catastrophes worldwide and pose a major threat to societies in the affected regions. Thus, governments and private companies have strong interests in improving the understanding of impacts from tropical cyclones in order to better prepare societies for possible disastrous impacts. This led to the development of natural catastrophe models that allow the quantification of expected ...Master Thesis -
Energy Optimization and Climate Control of a NEST Unit at Empa Dübendorf: A Data Predictive Control Approach
(2019)The building sector globally accounts for more than one third of the nal energy consumption. In industrialized countries about 50% of the consumed energy in buildings is used for heating, ventilation, and air conditioning. Consequently, increasing the energy e ciency of buildings has a relevant impact on climate change mitigation. Most residential space heating and cooling systems are currently controlled by a simple rule-based controller, ...Master Thesis -
Microstructural characterization of Fe-9%Cr ODS steel produced via selective laser melting
(2019)In this master thesis, the characteristics of reduced-activation ferritic Fe-9Cr oxide-dispersion-strengthened (ODS) steel, produced via mechanical alloying and laser-based additive manufacturing, are explored, with the main focus on the microstructure and the presence and size of the Y-based nano-oxides. Reference steel samples are also produced with the same processes, in order to characterize the impact of Yttria on the characteristics ...Master Thesis -

GPU Acceleration of ADMM for Large-Scale Convex Optimization
(2019)Large-scale convex optimization problems arise in various practical applications. Even though there exist many ecient methods for solving these problems, such as the alternating direction method of multipliers (ADMM), they may take minutes or even hours to compute solutions of very large problem instances. In this thesis we explore the possibilities of using a graphics processing unit (GPU) to accelerate ADMM. We use OSQP as a state-of-the-art ...Master Thesis -
Congestion-Aware Operation of Coordinated Autonomous Mobility-on-Demand Systems
(2019)With the advent of self-driving cars, Autonomous Mobility on Demand (AMoD) may become a very popular mode of transport in the near future because of its low price, convenience and other benefits. This study will explore the congestion effect of introducing a large fleet of autonomous vehicles to cities on a realistic simulation environment and will develop congestion-aware operation strategies for the fleet decision-making process. Refuting ...Master Thesis -
Pianificazione transfrontaliera per lo spazio funzionale di Chiasso
(2019)Premessa. Il lavoro che presento nasce in primis da un'esperienza diretta dei territori che sono oggetto di questa analisi, avendo trascorso oltre 10 anni in Ticino, prima come studentessa di architettura, poi come architetto. Molte delle problematiche che sono contenute in questo lavoro sono maturate durante gli anni di studio a Mendrisio. Viene proposta una visione di sviluppo a lungo termine, attuabile per fasi, dell'intera area di ...Master Thesis -
Conservatism and Scalability for Distributed Controller Synthesis of Interconnected Systems
(2019)This Master project concerns the problem of distributed controller synthesis for a special class of interconnected systems known as "decomposable systems" in a large-scale setting. Due to computational limitations, scalability constitutes one of the major concerns of the controller synthesis of such large-scale systems. One possibility to deal with this limitation is to decompose the synthesis conditions by enforcing some structure on the ...Master Thesis
