Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

Journal of Field Robotics, EarlyView.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

Transformação de um Datum Geodésico

Revista Brasileira de Cartografia
Estando o Brasil adotando como novo Datum para fins geodésicos e cartográficos o "DATUM SUL AMERICANO-1969" (South American Datum of 1969), é interessante que se faça uma pequena recordação nos conceitos relativos à transformação de um Datum para outro.

Injury Risks to a Migratory Freshwater Fish During Downstream Passage Through a Regulated Floodplain Outlet: A Case Study on Golden Perch (Macquaria ambigua)

River Research and Applications, EarlyView.
ABSTRACT River infrastructures such as weirs, dams, inlet and outlet regulators often impair connectivity, leading to degradation and loss of key habitats for riverine fishes. This also holds true for golden perch (Macquaria ambigua Richardson), a migratory species in Australia's Murray–Darling Basin.

Ground‐truthing of satellite imagery to assess seabird colony size: A test using Adélie penguins

Remote Sensing in Ecology and Conservation, EarlyView.
Adélie penguin colony size can be estimated from space using very high‐resolution (VHR; 0.3–0.6 m resolution) satellite imagery due to the contrast between their guano stain and the surrounding terrain. Our study assessed the utility of VHR imagery for making indirect assessments of changes in colony size.

Hybrid GNN and temporal encoder models for flood forecasting in the Vu Gia–Thu Bon River Basin

River, EarlyView.
Abstract Flood forecasting in river networks requires models that can capture both spatial dependencies across river basins and the temporal dynamics of hydrological processes. This study proposes a hybrid approach combining Graph Neural Networks (GNNs) with temporal sequence models, such as Long Short‐Term Memory (LSTM) networks and Transformer ...
