Corrosion damages and the importance of its prevention has been presented. An overview of previous research on Ni-B (and Ni-P) coatings has been presented. Synthesis and characterization of electrodeposited Ni-B and Ni-B-Y2O3 ...
Applications of Matlab optimization capabilities in the design of N-continuous stirred tank bioreactors connected in series
(
Hamad bin Khalifa University Press (HBKU Press)
, 2014 , Conference Paper)
The optimal design (variable volume) of continuous stirred tank reactors (CSTR's), in series, performing biological conversion of organic materials, was derived. The optimal design was based on the minimum overall reactor ...
