ADAPT: An Autonomous Forklift for Construction Site Operation
Journal of Field Robotics, EarlyView.ABSTRACT Efficient material logistics are critical in controlling costs and schedules in the construction industry. However, manual material handling remains prone to inefficiencies, delays, and safety risks. Autonomous forklifts offer a solution to streamline on‐site logistics, reducing reliance on human operators and mitigating labor shortages.

Environmental Stressors Influence Spatial Complexity in a Fluvial Macrophyte meadow
Remote Sensing in Ecology and Conservation, EarlyView.This research investigates the nonlinear relationships between environmental stressors and the fine‐scale spatial complexity of a fluvial macrophytes meadow. The use of multivariate spatial analysis allowed us to identify two major environmental gradients (nutrients and light) and two major complexity gradients (related to abundance and fragmentation).
