Social life of campus public spaces: Experimental study on the role of temporary interventions in fostering social activity
Ankita Singhvi, Kazuki Sakamoto
Our experimental study built on a tradition of quantitative urbanism, updating it to reflect recent developments in computer vision. We used cameras to track an area of Avenue Piccard in its current state, then intervened with temporary furniture such as o ...
2023Brown carbon absorption in the Mediterranean basin from local and long-range transported biomass burning air masses
This study examines the impact of light absorption from biomass burning (BB) brown carbon (BrC) in the Mediterranean basin from local and distant fire incidents during a typical fire season in August 2019 and under severe fire activity in August 2021. The ...
PERGAMON-ELSEVIER SCIENCE LTD2023Natural slicks on Lake Geneva: From small-scale effects to large-scale formation and distribution
Low wind speeds (< 4 m/s) are ubiquitous in many water bodies, yet the physical processes occurring at the air-water interface in this range are poorly understood. A notable example is smooth patches on the water surface, known as natural slicks, formed wh ...
EPFL2023Center-Based Decoupled Point Cloud Registration for 6D Object Pose Estimation
Mathieu Salzmann, Jiancheng Yang, Zheng Dang, Haobo Jiang
In this paper, we propose a novel center-based decoupled point cloud registration framework for robust 6D object pose estimation in real-world scenarios. Our method decouples the translation from the entire transformation by predicting the object center an ...
Ieee Computer Soc2023Optimal sensor placement for personal inhalation exposure detection in static and dynamic office environments
Modern health and productivity concerns related to air pollutant exposure in buildings have sparked the need for occupant-centric monitoring and ventilation control. The existing personal exposure monitoring is often restricted to stationary air quality se ...
PERGAMON-ELSEVIER SCIENCE LTD2023Aerobiology over the Southern Ocean – implications for bacterial colonization of Antarctica
Parts of the Antarctic are experiencing dramatic ecosystem change due to rapid and record warming, which may weaken biogeographic boundaries and dispersal barriers, increasing the risks of biological invasions. In this study, we collected air samples from ...
2022The impacts of the gas diffusion layer contact angle on the water management of the proton exchange membrane fuel cells: Three-dimensional simulation and optimization
Jan Van Herle, Hossein Pourrahmani
Water management of the proton exchange membrane fuel cell (PEMFC) is an important parameter to improve efficiency, especially in cold weather conditions. The generated water of the electrochemical reactions inside PEMFC may stay inside the cell and fill t ...
WILEY2022RRT*-Based Algorithm for Trajectory Planning Considering Probabilistic Weather Forecasts
Maryam Kamgarpour, Eduardo Andres Enderiz
Convective weather and its inherent uncertainty constitute one of the major challenges in the air traffic management (ATM) system, entailing both safety hazards and economic losses. In the present work, we propose a stochastic algorithm for trajectory plan ...
2021Informed scenario-based RRT∗ for aircraft trajectory planning under ensemble forecasting of thunderstorms
Maryam Kamgarpour, Eduardo Andres Enderiz
Thunderstorms represent a major hazard for flights, as they compromise the safety of both the airframe and the passengers. To address trajectory planning under thunderstorms, three variants of the scenario-based rapidly exploring random trees (SB-RRTs) are ...
2021The Red Harmful Plague in Times of Climate Change: Blooms of the Cyanobacterium Planktothrix rubescens Triggered by Stratification Dynamics and Irradiance
Alfred Johny Wüest, Bieito Fernandez Castro
Planktothrix rubescens is a harmful planktonic cyanobacterium, forming concentrated metalimnetic populations in deep oligo- and mesotrophic lakes, even after successful restoration. In Lake Zurich (Switzerland), P. rubescens emerged as a keystone species w ...
