Rhizosphere/Soil Microorganisms in the Phytoremediation of Biphenyl and Dioxane
(2015-07-29)
Biphenyl and dioxane biodegradation by poplar and willow rhizosphere microorganisms was studied in a phytoremediation test-plot contaminated with biphenyl and dioxane. A dioxane-degrading consortium enriched from the ...
Parameter Estimation Techniques for Nonlinear Dynamic Models with Limited Data, Process Disturbances and Modeling Errors
(2013-12-23)
In this thesis appropriate statistical methods to overcome two types of problems that occur during parameter estimation in chemical engineering systems are studied. The first problem is having too many parameters to estimate ...
Selection of Simplified Models and Parameter Estimation Using Limited Data
(2009-12-23)
Due to difficulties associated with formulating complex models and obtaining reliable estimates of unknown model parameters, modellers often use simplified models (SMs) that are structurally imperfect and that contain a ...
Laser Transmission Welding of Polybutylene Terephthalate and Polyethylene Terephthalate Blends
(2010-08-31)
Laser Transmission Welding (LTW) involves localized heating at the interface of two pieces of plastic (a laser transparent plastic and laser absorbing plastic) to be joined. It produces strong, hermetically sealed welds ...
Obtaining the Best Model Predictions and Parameter Estimates Using Limited Data
(2011-09-27)
Engineers who develop fundamental models for chemical processes are often unable to estimate all of the model parameters due to problems with parameter identifiability and estimability. The literature concerning these two ...
Nonlinear Observer Design Using Metric Based Potentials
(2015-10-03)
This thesis addresses observer design for nonlinear dynamical systems which can be approximated with dissipative Hamiltonian realizations. The design methods builds upon earlier developments that allow the approximate ...
Benders Decomposition-based Global Optimization for Natural Gas and Power Flow Systems
(2016-04-28)
Mixed-integer nonlinear programming (MINLP) framework has been attracting more and more attention since late last century. It can be applied to address various process systems engineering problems, such as process design ...
Measurement System Design for Chemical Processes
(2011-06-16)
The problem of measurement system design for stochastic linear systems, a popular modeling strategy for chemical processes, is addressed. A multi-objective optimization approach is used. The design metrics are the capital ...
Characterization of Thermo-Fluid Transport Properties of Coated and Uncoated Open-Cell Metal Foam Monoliths
(2011-12-13)
An improved steady-state method combining experiment and mathematical modelling has been developed to characterize the scalable convective heat transfer coefficient, hvol [W*m^(-3)*K^(-1)], of uncoated and catalyst-support ...
Living Radical Polymerization in Aqueous Dispersed Systems with Water-Soluble Catalysts
(2015-10-03)
Living radical polymerization is an important technique for synthesizing advanced macromolecules including block copolymers. Since its discovery in the early 1990s the capability of the field has expanded with new types ...
