Non-Spatial and Spatial Statistics for Analysing Human Perception of the Built Environment
(2018)The world is rapidly urbanising, which makes the liveability of cities an important issue in our times. New sources of data on urban citizens including social media, video footage, and even fitness data, are also becoming increasingly available. This study is motivated by these two trends. We analyse data gathered in a Virtual Reality experiment to find correlations between features of the urban environment and people’s perceptions of ...Master Thesis -
The Influence of the Resolution of Topography and Surface Fields on the Simulation of Orographic Moist Convection
(2018)Moist convection has a strong impact on the Earth’s water and energy budgets. It redistributes moisture and heat vertically and thus changes the stratification ofthe atmosphere. The associated clouds interact with radiation and generate precipitation. Convective precipitation can be very intense and may cause flooding and trigger land slides. A good understanding and simulation of moist convection is therefore of crucial importance for ...Master Thesis -
Distributed Join Result Materialization over High-Performance Networks
(2017)Distributed Joins over a network have been researched for decades, usually focusing on adapting the join to the network connecting the nodes holding the relations. Most research has gone into optimizing the join itself, i.e. the identification of matching tuples, however the effective materialization of the join result is equally important. The main performance issue identified by materialization strategies is that the network performs ...Master Thesis -

Travelling waves in somitogenesis: collective cellular properties emerge from time-delayed juxtacrine oscillation coupling
(2017)The sculpturing of the vertebrate body plan into segments begins with the sequential formation of somites in the presomitic mesoderm (PSM). The rhythmicity of this process is controlled by travelling waves of gene expression which sweep across the PSM. These kinetic waves emerge from coupled cellular oscillators and travel in the direction of an increasing gradient of oscillation period. The oscillations are driven by autorepression of ...Master Thesis -
Dynamic Range Low-power Wireless Protocols for Environmental Monitoring
(2018)In the rapidly advancing world of wireless embedded systems, sensor networks (WSNs) are becoming increasingly more applicable for data gathering applications. When designed for such applications, the design goals are most often defined in terms of communication reliability, flexible data-rates, and network life-time. One of the application domains that will benefit from improvement in these metrics, is the area of environmental ...Master Thesis -
ALPINE RANDREGIONEN - Herausforderungen und Strategien für eine nachhaltige Raumentwicklung im Berggebiet
(2018)Die Berggebiete und weitere Randregionen der Schweiz sind seit Jahren von einem Bevölkerungsrückgang betroffen. Als Gegenstück zu den Zentren, wird der Begriff „Randregion“ mit einem Problembezug, wie schlechter Wirtschaftslage, Überalterung oder Mangel an qualifizierten Arbeitskräften, in Verbindung gebracht. In dieser Arbeit werden diese Räume genauer betrachtet und raumplanerische Perspektiven aufgezeigt. Die Arbeit macht durch ...Master Thesis -
Entwicklungsstrategie zu öffentlichen Bauten und Anlagen – Förderung der Innenentwicklung durch die Gemeinden
(2018)Die Herausforderungen und Ansprüche an eine Innenentwicklung erfordern von allen raumrelevanten Akteuren ein angepasstes Rollenverständnis und adaptierte Vorgehensweisen. Innenentwicklungen sollen am richtigen Ort erfolgen, innerhalb der Siedlung und gut durch den öffentlichen Verkehr erschlossen. Am richtigen Ort sind jedoch oft komplexe Situationen anzutreffen. Im Gegensatz zur Siedlungsentwicklung am Rand, kann die Arbeit der ...Master Thesis -
Die Zukunft der Einkaufszentren – Chancen und Herausforderungen für die Raumentwicklung
(2018)Die Einkaufszentren entstanden im Zuge der Massenmotorisierung und der modernen Konsumgesellschaft in den 1950er Jahren in den USA. Das erste Einkaufszentrum der Schweiz wurde 1970 in Spreitenbach im Kanton Aargau gebaut. Eine Vielzahl an Einkaufszentren eröffnete in den folgenden Jahrzehnten, sich am entstehenden Nationalstrassennetz orientierend, ihre Tore. Diese Entwicklung hatte eine grosse Auswirkung auf die Siedlungsstruktur und ...Master Thesis -
Beitrag der bestehenden Einfamilienhausquartiere zur Innenentwicklung
(2018)Die Strategie der Siedlungsentwicklung nach innen, kurz Innenentwicklung, ist spätestens seit dem Inkrafttreten des revidierten Raumplanungsgesetzes 2014 zentraler Bestandteil der räumlichen Entwicklungsstrategie der Schweiz. Wegen ihrer engmaschigen Grundstücksstruk-turen, der vielen nicht professionellen Grundeigentümer und der ausgeprägten emotionalen Bindung liegen Einfamilienhausquartiere nicht im Fokus der Nachverdichtung. Der Bestand ...Master Thesis -
Flexible parking infrastructures: The use of Real Option to account for future mobility uncertainty
(2018)Design of embedded parking infrastructures assumes the parking demand to be stable over the infrastructure’s life-time. However, the looming mobility trend shift towards shared automated vehicles (AVs) make future parking needs highly uncertain and parking demand could thus disappear over an infrastructure’s life-time. A method is needed to optimize the parking design considering uncertainty of future demand so its use can be transitioned ...Master Thesis -
Multiple Query Execution through SQL Rewriting
(2017)Current database systems typically process queries in a query-at-a-time fashion without considering common subexpressions that can be shared. Such a design leads to suboptimal processing, i.e., lower throughput, higher latency, and poor scalability. Taking advantage of sharing common subexpressions in batches or streams of concurrent queries is one way to mitigate those problems. Another option is to implement new shared operators in ...Master Thesis -
36 Component Seismic Data: Investigating Translational and Rotational Components in Exploration Seismology
(2016)In conventional multicomponent seismic exploration, the wavefield is recorded by measuring translational motions in three directions using three-component sensors. A novel approach in land seismic acquisition is to additionally record the rotational components of the wavefield around the various Cartesian axes and to combine them with translational measurements. Additional rotational measurements provide the opportunity to locally extract ...Master Thesis -
Non-linear Control of Quad-copters via Approximate Dynamic Programming
(2018)Approximate Dynamic Programming has proven to be successful in many discrete state applications such as playing the games of Tetris or chess. However, not so many applications involving continuous state space dynamics have been proposed. In this thesis we study the possibilities of applying these same techniques to the continuous, non-linear, high dimensional dynamics of a quad-rotor vehicle, by using the Linear Programming approach to ...Master Thesis -
Traffic Interaction with Platoon (TRIP): safe gap expansion and reduction between vehicles in a platoon
(2018)In this thesis, we study the interaction of a single vehicle with a platoon. More specifically, we consider the case in which the gap between two vehicles in the platoon has to be expanded and then reduced. This facilitates a single vehicle to change lanes, enter into the expanded gap, and leave after a while. As a first step, we review the literature of platoon formation, tracking of a reference velocity as well as of a spacing policy. ...Master Thesis -
