Generalsanierung in Bayern - Kritik an DB-Plänen: Die DB hat heute ihre Pläne für die Generalsanierung wichtiger Schienenkorridore in Bayern in den Jahren 2026 bis 2030 vorgestellt. Der Fahrgastverband PRO BAHN ist mit den Planungen nicht ganz einverstanden und nennt sie für einige Korridore nicht ausgereift. Zudem fehle es an geeigneten und ausreichend ertüchtigten Umleitungsstrecken. PRO BAHN Bayern schlägt daher vor, die Sanierung der Strecken…

Fin du véhicule thermique : pourquoi et comment y parvenir ? | Terra Nova
Dans le cadre de la campagne pour les élections européennes 2024, nous avons demandé à différents experts de formuler des recommandations sur plusieurs questions stratégiques pour l’avenir de l’Union européenne. Nous ouvrons cette série avec une contribution de Jean-Philippe Hermine, directeur de l’Institut Mobilités en Transition (IMT), à qui nous avons posé la question de la fin du véhicule thermique. Alors que certains émettent des doutes sur les orientations du Green Deal…

Physics-Informed Graph Neural Networks for Water Distribution Systems
Water distribution systems (WDS) are an integral part of critical infrastructure which is pivotal to urban development. As 70% of the world's population will likely live in urban environments in 2050, efficient simulation and planning tools for WDS play a crucial role in reaching UN's sustainable developmental goal (SDG) 6 - "Clean water and sanitation for all". In this realm, we propose a novel and efficient machine learning emulator, more precisely, a physics-informed deep learning (DL) model…

Agrivoltaics for fir trees
German researchers are studying using an overhead solar PV system, designed to be removable and reusable, as a sunshade for young fir trees. The pilot, located at a quartz sand excavation site, will be monitored to compare growth and water consumption with an adjacent unshaded tree plot.

Distributed Optimization with Consensus Constraint for Multi-Robot Semantic Octree Mapping
This work develops a distributed optimization algorithm for multi-robot 3-D semantic mapping using streaming range and visual observations and single-hop communication. Our approach relies on gradient-based optimization of the observation log-likelihood of each robot subject to a map consensus constraint to build a common multi-class map of the environment. This formulation leads to closed-form updates which resemble Bayes rule with one-hop prior averaging. To reduce the amount of information e…

Climate change and its consequences on the climatic zoning of Coffea canephora in Brazil - Environment, Development and Sustainability
Coffee production has a large share in Brazilian agribusiness and a cultural and social importance in the country. Worldwide, Brazil is the largest producer of arabica coffee and the second largest of canephora species. In 2020, national production was 14.3 million bags of canephora coffee. Few studies on canephora coffee adaptation to climate changes can be found in the literature. Thus, our goal was to identify areas suitable for Coffea canephora cultivation in Brazil under CMIP-5 climate cha…
