Application of back-propagation neural networks to the modeling and control of multiple-input, multiple-output processes
Certain properties of back-propagation neural networks have been found to be useful in structuring models for multiple-input, multiple-output (MIMO) processes. The network's simplicity and its ability to identify the ...
Modeling and optimization of a two-stage regenerator fluid catalytic cracking unit
In Petroleum refining, the Fluid Catalytic Cracking Unit (FCCU) is the critical stage in the processing of heavy hydrocarbon oils into more valuable gasoline and lighter products. In the FCCU process, the catalyst becomes ...
Transient permeate flux analysis, cost estimation, and design optimization in crossflow membrane filtration
A generalized model is formulated to predict the time-dependent permeate flux by extending previous models to include the particle transport mechanisms of Brownian diffusion, shear-induced diffusion, inertial lift and ...
Analysis of metabolic flux of secondary metabolite pathways in Catharanthus roseus hairy root cultures
Catharanthus roseus, a tropical plant, produces the valuable anti-cancer compounds, vincristine and vinblastine in extremely low amounts. My research objectives were to examine the response of plant secondary metabolism ...
Interactions of the platelet GP Ib-IX-V complex with immobilized von Willebrand factor under flow conditions
Platelets play key roles in physiology, such as the arrest of bleeding following vascular injury, and in pathology, such as mural arterial thrombosis. The initial step in both processes is platelet adhesion to von Willebrand ...
In vivo phosphorus-31 and carbon-13 nuclear magnetic resonance spectroscopy to study cellular metabolism
Nuclear magnetic resonance spectroscopy has emerged as a valuable tool for engineers for noninvasive, real-time studies of cellular metabolism. Two applications of NMR for studying cellular metabolism were investigated in ...
