Analysis of the suitability for ecotourism in Beira Baixa region using a spatial decision support system based on a geographical information system

Regional Science Policy &Practice, EarlyView., 2022
Abstract Ecotourism can contribute to the conservation of environmental values, as well as to the development of positive synergies between agents in the tourism sector, tourists and the local population. The growing interest in tourism offers with low environmental impact, which support the local economy, translates into a competitive advantage for ...

Eigenfeature‐enhanced deep learning: advancing tree species classification in mixed conifer forests with lidar

Remote Sensing in Ecology and Conservation, EarlyView.
Workflow for tree species classification using lidar data. Steps include preprocessing (normalization, noise removal, CHM creation), tree segmentation, eigenfeature extraction, and 2D CNN training/validation. Blue, yellow, and red indicate training, validation, and testing image sets, respectively.

Location‐Assisted Graph‐Based User Scheduling in Multi‐User MIMO LEO NTN Systems

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper addresses user clustering and scheduling for multi‐user MIMO low Earth orbit nonterrestrial network systems in full frequency reuse. Since the number of on‐ground user terminals is usually much higher than the number of on‐board LEO satellite antennas, user scheduling becomes a fundamental task.
