Study of flexible operating conditions in variable-speed hydraulic turbines : advanced models and experimental validation
This PhD thesis is framed within the XFLEX HYDRO project, funded by the European Union's Horizon 2020 research and innovation program under grant agreement No 857832. The ultimate objective of the XFLEX HYDRO project is to increase hydropower potential in ...
EPFL2024A Review of Modeling, Design and Performance Assessment of Linear Electromagnetic Motors for High-Speed Transportation Systems
Mario Paolone, André Hodder, Lucien André Félicien Pierrejean, Simone Rametti
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, ...
2024Artificial intelligence of things for smart cities: advanced solutions for enhancing transportation safety
Jeffrey Huang, Simon Elias Bibri
In the context of smart cities, ensuring road safety is crucial due to increasing urbanization and the interconnected nature of contemporary urban environments. Leveraging innovative technologies is essential to mitigate risks and create safer communities. ...
Springernature2024pNEUMA dataset
Nikolaos Geroliminis, Emmanouil Barmpounakis
pNEUMA is an open large-scale dataset of naturalistic trajectories of half a million vehicles that have been collected by a one-of-a-kind experiment by a swarm of drones in the congested downtown area of Athens, Greece. A unique observatory of traffic cong ...
EPFL Infoscience2024STATNet: Spatial-temporal attention in the traffic prediction
Alexandre Massoud Alahi, Seyed Mohamad Moghadas, Amin Gheibi
Recent traffic flow prediction methods are lacking abilities to determine predictive features. Thus, they will propagate the error in the next timestamps. In this paper, first, we assess the role of spatial and temporal features on the traffic speed predic ...
2022Algorithms for Walking Speed Estimation Using a Lower-Back-Worn Inertial Sensor: A Cross-Validation on Speed Ranges
Kamiar Aminian, Anisoara Ionescu, Abolfazl Soltani
Walking/gait speed is a key measure for daily mobility characterization. To date, various studies have attempted to design algorithms to estimate walking speed using an inertial sensor worn on the lower back, which is considered as a proper location for ac ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2021Bidirectional Recoil Leaders in Upward Lightning Flashes Observed at the Säntis Tower
Marcos Rubinstein, Mohammad Azadifar, Antonio Sunjerga, Amirhossein Mostajabi
We report the observation of three negative upward flashes recorded by a high-speed camera at the Säntis Tower during the Summer of 2019. The camera was operating at 10,000 fps and an exposure time of 99 μs. Simultaneous measurements of the lightning curre ...
