3D DSS - EC. Enhancing the 3D DSS for Supporting the Planning of Electric Power Systems: Integration of Underground Cables
(2020)The project «3D DSS – EC» extended an existing 3D Decision Support System (3D DSS) for the calculation and visualization of planning areas and corridors of electrical power lines with the integration of earth cables. For this purpose, several methods were developed to determine locations that are particularly suitable for the construction of a new high-voltage power line – either overhead or underground – using a wide range of approaches ...Report -
Das Gewicht der Schweiz
(2020)Übergewicht wird multifaktoriell verursacht und hat in der Schweiz seit den 1990er Jahren stark zugenommen. Eine breit abgestützte Untersuchung der involvierten Kofaktoren würde es ermöglichen, Risikofaktoren und damit auch Interventionsprogramme präziser als bisher zu definieren. Für die erwachsene Bevölkerung in der Schweiz wurden bisher die bestehenden gesamtschweizerischen bevölkerungsweiten Studien zu Übergewicht noch nie zusammengefasst ...Report -
First-Kind Boundary Integral Equations for the Dirac Operator in 3d Lipschitz Domains
(2020)SAM Research ReportWe develop novel first-kind boundary integral equations for Euclidean Dirac operators in 3D Lipschitz domains comprising square-integrable potentials and involving only weakly singular kernels. Generalized Garding inequalities are derived and we establish that the obtained boundary integral operators are Fredholm of index zero. Their finite dimensional kernels are characterized and we show that their dimension is equal to the number of ...Report -
MOBIS-COVID19/31
(2020)Arbeitsberichte Verkehrs- und RaumplanungOn March 16, 2020, 3700 participants who completed the MOBIS study between September 2019 and January 2020 were invited to reinstall the GPS Logger and Travel Diary App ‘Catch-My-Day’, developed by MotionTag, to record their mobility behaviour during the period of special measures implemented to control the spread of the Corona Virus. The first 4 weeks of mobility data from the original MOBIS Study is taken for each participant as a ...Report -

Die Schweizer Selbständigerwerbenden in der Covid19-Pandemie
(2020)Der Bundesrat hat am 13. März einen partiellen Lockdown der Schweiz beschlossen, der viele Betriebe stark betroffen hat. In der Woche nach Ostern (14.-20. April) haben wir die Inhaberinnen und Inhaber von 1'011 kleinen und mittleren Unternehmen (KMU) zu den Auswirkungen der Krise auf das Unternehmen und ihre persönliche Situation befragt. 409 der befragten Selbständigen führen einen Betrieb, der in dieser Zeit geschlossen war. Es zeigt ...Report -
Challenges and opportunities for timber buildings in the swiss real estate market
(2020)Financing the Low-Carbon Economy. Instruments, Barriers and RecommendationsIn this case study, we present an economic and environmental prospective analysis for the use of timber buildings in Switzerland. Wood building materials can avoid emissions caused during concrete and steel production processes and tie up CO2 for decades. Our analysis assess the effects of applying carbon storage credits to such timber projects. We first calculated the environmental impact and CO2 storage for timber buildings using a Life ...Report -
Wave interaction with subwavelength resonators
(2020)SAM Research ReportThe aim of this review is to cover recent developments in the mathematical analysis of subwavelength resonators. The use of sophisticated mathematics in the field of metamaterials is reported, which provides a mathematical framework for focusing, trapping, and guiding of waves at subwavelength scales. Throughout this review, the power of layer potential techniques combined with asymptotic analysis for solving challenging wave propagation ...Report
