in dynamic analysis of floating structures, the designer needs to know the wave forces due to incident and scattered waves on the structure. in this work, the flow field around the body is solved based on the potential theory with considering the free surface and sea bed effects. using this theory, the wave forces exerted on two typical sea buoys with spherical and disc-type bodies are determin...

nowadays, a noticeable part of the relations among the states turn around the environment protection. therefore, the right for ever-creasing use of the existing resources of this inland sea cannot be exclusive to any caspian state and the aftermath involves all countries of this basin. in this respect, agreement on political border and boundaries with the caspian sea?s ecosystem is a difficult ...

A proper understanding of the risk associated with sea-level change can only be attained by adherence to accurate terminology. In particular, it is vital to recognize the distinction between changes in eustatic sea-level, which correspond to changes in a notional world-wide average, and changes in local relative sea-level (LRSL), which correspond to changes in actual sea-levels at real and part...

Current methods for off-road navigation using vehicle and terrain models to predict future vehicle response are limited by the accuracy of the models they use and can suffer if the world is unknown or if conditions change and the models become inaccurate. In this paper, an adaptive approach is presented that closes the loop around the vehicle predictions. This approach is applied to an autonomo...
