How Hybrids Work
Most hybrids use several advanced technologies: Regenerative Braking. Regenerative braking recaptures energy normally lost during coasting or braking. It uses the forward motion of the wheels to turn the motor. This generates electricity and helps slow the vehicle. Electric Motor Drive/Assist. The electric motor provides power to assist the ...

A GMDH Approach to Modelling Gibbsite Solubility in Bayer ...
The most widely employed industrial process for producing alumina (Bayer process) involves the dissolution of available aluminium hydroxide minerals present in raw bauxite into high temperature sodium hydroxide solutions. On cooling of the solution, or liquor in the industrial vernacular, Al is precipitated from solution in the form of gibbsite (Al(OH)3).
