Testing the Properties of Radon Barrier Materials and Home Ventilation to Mitigate Indoor Radon
Indoor radon is the second cause of lung cancer.Mitigation strategies are Low Leg Recliner based on (i) building protection with radon barrier materials, (ii) increasing home ventilation or (iii) room pressurization.A scale model room created with a porous ignimbrite rich in radon precursors was used as an analogue to test the indoor radon reductio
Cooperative path planning of USV and UAV swarms under multiple constraints
ObjectivesFor achieving navigational safety and continuous communication link between swarms of unmanned marine vehicle (UMV) during mission execution, the cooperative path planning of unmanned surface vehicle (USV) and unmanned aerial vehicle (UAV) swarms is studied.MethodsKeep-in and keep-out geo-fences are used to carry out scene modelling, and
