The problem of sandbar migration on the storm timescale is revisited with a 3D wave-resolving hydro-sedimentary model. latter presents an intermediate approach between expensive two-phase flow models and highly parametrized wave-averaged models. Innovative features include use weakly compressible assumptions in hydrodynamics morphological acceleration bed changes to speed up numerical simulatio...

This paper describes 3D animation techniques for dynamic behavior such as load balancing of parallel distributed event simulation (PDES) on the basis of motion equations in a dynamic system. First, we propose a new mapping scheme of trace data obtained from PDES systems to a dynamic system to visualize simulation progression, and then, shows 3D animation snapshots using the trace data of the ec...

Three-dimensional (3D) wireless sensor networks have attracted a lot of attention due to their great potential usages in both commercial and civilian applications, such as environmental data collection, pollution monitoring, space exploration, disaster prevention, and tactical surveillance. Topology control in 3D sensor networks has been studied recently, and different 3D geometric topologies w...
