Magnetically-levitated drives are interesting in applications which demand a combination of reliable operation and high speeds. In the latter domain, slotless stators are recognized as the most suitable, as they deliver higher power density and lower speed ...
The current global energy landscape is characterized by an increasing demand for affordable and sustainable energy sources, leading to an ever increasing integration of intermittent renewable energy resources into the grid. The intermittent nature of these ...
In the last decades, transportation demand growth has played a major role in the increase of global CO2 footprint. At the same time, a number of countries have scheduled measurable and substantial cutback of CO2 emissions by 2050. As the transportation sec ...

Linear electromagnetic motors (LEMs) have been proposed, developed and used to propel high-speed (i.e. speed > 100 m/s) levitating vehicles. However, few real implementations have demonstrated the feasibility of these machines at such speeds. Furthermore, ...
We present optical tomography methods for a 3D refractive index reconstruction of weakly scattering objects using LED light sources. We are able to record holograms by minimizing the optical path difference between the signal and reference beams while sepa ...
Dans une localité qui subit une densification massive vers le sud, le bord du lac reste encore épargné par cette urbanisation anarchique. Cependant, on y trouve principalement des résidences de standing, des activités saisonnières et touristiques réservées ...

Today private vehicles in the cities is a high problem, due to the congestion they create, their pollution and their use of public space. Various alternatives exist, as public transportation and other modes, and still the part of people using cars remain t ...
The overground speed is a key component of running analysis. Today, most speed estimation wearable systems are based on GNSS technology. However, these devices can suffer from sparse communication with the satellites and have a high-power consumption. In t ...
This master's project studies the role of ride-splitting incentives in the service level, total revenue, and trac impact of a ride-sourcing platform, which is built as a discrete event simulator using simulated taxi data within a congestible road network o ...
