Datacubes as enabler for advanced decision support systems in land management

Land Degradation &Development, Volume 35, Issue 11, Page 3579-3592, 15 July 2024.
Abstract Informed, wise, land management has been a challenge since a long time, but has gained extra importance through the need for responding to climate change effects. The European Green Deal is one example of a concertation effort in a world where data availability, sharing options, and just‐in‐time exploitation are not entirely solved.

A composite spread spectrum sequence for underwater acoustic signal acquisition

IET Communications, Volume 18, Issue 11, Page 689-700, July 2024.
This article explores the acquisition performance of spectrum spread sequence based on underwater acoustic (UWA) channel. To overcome the limitations of conventional sequences, a composite chaotic orthogonal sequence (CCOS) is proposed as spectrum spread sequence and a source‐target model is constructed for simulation. In addition, a parallel algorithm
