Hydrodynamic coefficients are the foundation of unmanned underwater vehicles modeling and controller design. In order to reduce identification complexity and acquire necessary hydrodynamic coefficients for controllers design, the motion of the unmanned underwater vehicle was separated into vertical motion and horizontal motion models. Hydrodynamic coefficients were regarded as mapping parameter...

Hydrodynamic model generally deals with enormous amount of data and utilizes huge computational resources for simulation. Powerful and robust servers with extensive storage capabilities are therefore desirable for rapid simulation. Unfortunately, it is not always possible for an individual to effort those kind of facilities whereas a central computer system can be the viable alternative to serv...

For the needs of high electron mobility transistors (HEMTs) optimization a reliable software simulation tool is required. Due to the high electric field in the device channel a hydrodynamic approach is used to properly model the electron transport. We modify an existing hydrodynamic mobility model in order to achieve a better agreement with Monte Carlo (MC) simulation data and measured DC and A...

Abstract Conservation and improvement of water quality in bodies is an important matter to maintain all its uses as well other human necessities like microclimate regulation leisure. Lakes reservoirs have a complex circulation behavior with vertical temperature profiles changes along the time, resulting differences density stratification condition. This characteristic can directly affect condit...
