RAST: Risk-Aware Spatio-Temporal Safety Corridors for MAV Navigation in Dynamic Uncertain Environments

Autonomous navigation of Micro Aerial Vehicles (MAVs) in dynamic and unknown environments is a complex and challenging task. Current works rely on assumptions to solve the problem. The MAV's pose is precisely known, the dynamic obstacles can be explicitly segmented from static ones, their number is known and fixed, or they can be modeled with...

Challenges of prefabricated housing in China: Supply chain, Stakeholders, and Transaction costs

Recently, the implementation of prefabricated housing (PH) has become prevalent in China to achieve sustainability while ensuring green construction, innovative products, and higher quality. However, numerous challenges arise, such as the overrun costs, inexperienced workers, and the inefficient management process. High transaction costs (TCs)...

Stakeholder Perceptions of Transaction Costs in Prefabricated Housing Projects in China

Prefabrication has the potential to improve the efficiency and sustainability of housing production. However, there are various challenges in the realization of prefabricated housing (PH) from the stakeholder's perspective. Transaction costs (TCs) theory provides a particular angle that explains the invisible costs within transactions. This...
