... areas, rivers, natural and artificial lakes. The ASV acts as a bridge for communication with a remote station, that in this way can receive data from the ROV, avoiding the necessity of a supply vessel to operate the ROV (Scaradozzi, Conte and Sorbi, 2012; Conte et al., 2016). Examples of cooperation...

In the former, CFD solver gathers DCI (Domain Connectivity Information) and surface area weight coefficients from output files in parallel way, but in the later, CFD solver and overset grid solver run in different MPI...

...). The IUDA is designed in order to visualize the sea ice shape and topography from the "backside" by using acoustic technologies and optical technologies, at the same time it will measure sea water components under the sea ice in detail using science sensors. Since it is difficult to communicate...

.... An autonomous underwater vehicle (AUV) can perform observations in their areas. The vehicle must communicate with a terminal end of the observatory to obtain observation data in quasi-realtime. The batteries of the AUV must be also charged from the observatory. Underwater electromagnetic (UEM) transmission...
