This study examines the impact of ICT growth on the productivity effects of transportation infrastructure. Using dynamic panel data of OECD member countries, the study finds econometrically meaningful results on examining the complementarity between ICT and transportation infrastructures. The...

In this study, we combined the advantages of bitmaps and remote sensing data to reconstruct three-dimensional (3D) harbor models and establish a new simulation navigation system. The models employ triangular elements to reconstruct the topology relationships between the seabed and the harbor...

Human hazards can represent a significant risk to the population and cause huge economic damage in many urbanized regions. In order to be able to identify risk hot spots and implement targeted risk reduction measures, decision makers need to have a clear picture of the risk situation in their...
