Influence of sun cups on surface albedo of wet Alpine snowpack
Michael Lehning, Mathias Thierry Pierre Bavay, Francesca Carletti
In high elevation Alpine areas, characterised by high snow accumulation and radiation-driven melt processes, the formation of peculiar ablation features called sun cups can be observed. Sun cups likely influence the energy and mass balance of the wet snowp ...
2024Mapping drivers of tropical forest loss with satellite image time series and machine learning
Devis Tuia, Gaston Jean Lenczner, Jan Dirk Wegner, Jan Pisl, Marc Conrad Russwurm, Lloyd Haydn Hughes
The rates of tropical deforestation remain high, resulting in carbon emissions, biodiversity loss, and impacts on local communities. To design effective policies to tackle this, it is necessary to know what the drivers behind deforestation are. Since drive ...
Iop Publishing Ltd2024Relative plus constructions
Let h be a connective homology theory. We construct a functorial relative plus construction as a Bousfield localization functor in the category of maps of spaces. It allows us to associate to a pair (X,H), consisting of a connected space X and an hperfect ...
2023Towards a fully physical representation of snow on Arctic sea ice using a 3D snow-atmosphere model
Michael Lehning, Adrien Michel, Mahdi Jafari, Océane Hames, Nander Wever, Marc Schneebeli Zeugin, David Nicholas Wagner
In high elevation Alpine areas, characterised by high snow accumulation and radiation-driven melt processes, the formation of peculiar ablation features called sun cups can be observed. Sun cups likely influence the energy and mass balance of the wet snowp ...
2023Affordance segmentation of hand-occluded containers from exocentric images
Visual affordance segmentation identifies the surfaces of an object an agent can interact with. Common challenges for the identification of affordances are the variety of the geometry and physical properties of these surfaces as well as occlusions. In this ...
Los Alamitos2023Clustering and Informative Path Planning for 3D Gas Distribution Mapping: Algorithms and Performance Evaluation
Alcherio Martinoli, Chiara Ercolani, Lixuan Tang, Ankita Arun Humne
Chemical gas dispersion can represent a severe threat to human and animal lives, as well as to the environment. Constructing a map of the distribution of gas in a fast and reliable manner is critical to ensure accurate monitoring of at-risk facilities and ...
2022Mapping Active Site Geometry to Activity in Immobilized Frustrated Lewis Pair Catalysts
Shubhajit Das, Rubén Laplaza Solanas, Jacob Terence Blaskovits
The immobilization of molecular catalysts imposes spatial constraints on their active site. We reveal that in bifunctional catalysis such constraints can also be utilized as an appealing handle to boost intrinsic activity through judicious control of the a ...
2022A Lightweight Goal-Based model for Trajectory Prediction
We present a lightweight goal-based model for multimodal, probabilistic trajectory prediction for urban driving. Previous conditioned-on-goal methods have used map information in order to establish a set of potential goals and then complete the correspondi ...
IEEE2022Mapping forest in the Swiss Alps treeline ecotone with explainable deep learning
Devis Tuia, Benjamin Alexander Kellenberger, Thiên-Anh Claris Nguyen
Forest maps are essential to understand forest dynamics. Due to the increasing availability of remote sensing data and machine learning models like convolutional neural networks, forest maps can these days be created on large scales with high accuracy. Com ...
Elsevier2022Fine-grained population mapping from coarse census counts and open geodata
Devis Tuia, Benjamin Alexander Kellenberger, Muhammad Imran
Fine-grained population maps are needed in several domains, like urban planning, environmental monitoring, public health, and humanitarian operations. Unfortunately, in many countries only aggregate census counts over large spatial units are collected, mor ...
