Obstructions to Motion Planning by the Continuation Method
(20130103)The subject of this thesis is the motion planning algorithm known as the continuation method. To solve motion planning problems, the continuation method proceeds by lifting curves in state space to curves in control space; ... 
Obtaining a quality model for manufacturing systems and establishing a maintenancequality link
(20080625)This thesis describes the application of the stochasticflowmodeling (SFM) approach to represent the quality behavior of a manufacturing system. Initially, a simple, oneproduct type SFM is discussed and then a more ... 
Obtaining the Best Model Predictions and Parameter Estimates Using Limited Data
(20110927)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 ... 
On the regioselectivity of Hatom abstraction from model polyolefins by alkoxyl radicals
(20111024)Solventfree peroxideinitiated polymer modifications are widely used to improve the physical and/or chemical properties of commodity plastics and elastomers. Although the reactions that underlie polymer grafting are known, ... 
OnLine Optimization for a BatchFed Copolymerization Reactor with Partial State Measurement
(20091006)Polymerization processes require adequate monitoring to ensure that the final product meets specification. Various online measuring techniques have been developed and implemented to track polymer properties in reactors. ... 
Optimal Utilization of Natural Gas Pipeline Storage Capacity Under Future Supply Uncertainty
(Elsevier, 20200507)The ability of pipelines to store gas by increasing their operating pressure, or linepacking, is a common operational practice used to mitigate future operational uncertainty. The optimal operation of a gas pipeline network ... 
Optimization and Biological Characterization of Decellularized Adipose Tissue Scaffolds for Soft Tissue Reconstruction
(20140130)It would be a great advantage in reconstructive surgery to have an offtheshelf biomaterial to promote regeneration and volume augmentation following soft tissue damage. With this longterm objective, human adipose tissue ... 
Optimized inkjetprinted silver nanoparticle films: theoretical and experimental investigations
(Royal Society of Chemistry, 20180529)We study the influence of inkjet printing scheme and sintering parameter on the electrical resistivity of multilayer silver nanoparticle films. A central composite Design Of Experiments (DOE) is employed to maximize ... 
Order in Oscillatory Shear Flow
(201812)We examine the second order orientation tensor for the simplest molecular model relevant to a polymeric liquid in largeamplitude oscillatory shear flow (LAOS), the rigid dumbbell suspension. For this we use an approximate ... 
Orientation Distribution Function Pattern for Rigid Dumbell Suspensions In Any Simply Shear Flow
(201809)For rigid dumbbells suspended in a Newtonian solvent, the viscoelastic response depends exclusively on the dynamics of dumbbell orientation. The orientation distribution function ψ (θ ,φ ,t) represents the probability of ... 
Orientation in LargeAmplitude Oscillatory Shear
(20140930)We examine the simplest relevant molecular model for largeamplitude oscillatory shear flow of a polymeric liquid: the dilute suspension of rigid dumbbells in a Newtonian solvent. We find explicit analytical expressions ... 
Padé Approximant for Normal Stress Differences in LargeAmplitude Oscillatory Shear Flow
(201711)Analytical solutions for the normal stress differences in largeamplitude oscillatory shear flow (LAOS), for continuum or molecular models, normally take the form of the first few terms of a series expansion in the shear ... 
Padé Approximants for LargeAmplitude Oscillatory Shear Flow
(20150317)Analytical solutions for either the shear stress or the normal stress differences in largeamplitude oscillatory shear flow, both for continuum or molecular models, often take the form of the first few terms of a power ... 
Parameter estimation in nonlinear continuoustime dynamic models with modelling errors and process disturbances
(20080625)Modelbased control and process optimization technologies are becoming more commonly used by chemical engineers. These algorithms rely on fundamental or empirical models that are frequently described by systems of differential ... 
Parameter Estimation Techniques for Nonlinear Dynamic Models with Limited Data, Process Disturbances and Modeling Errors
(20131223)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 ... 
Parameter identifiability of biochemical reaction networks in systems biology
(20080814)In systems biology, models often contain a large number of unknown or only roughly known parameters that must be estimated through the fitting of data. This work examines the question of whether or not these parameters ... 
Parameter Inference and Estimability Analysis for Nonlinear MultiResponse Systems by Means of Profiling
(20141001)Determining the inference bounds for parameter estimates in multiresponse models is a challenge for research and industry since potential codependencies among responses add to the complexity of the problem. Statistical ... 
Peroxide Curable Butyl Rubber Derivatives
(20120706)Isobutylenerich elastomers bearing functional groups that engage Narylmaleimides in CH bond addition and/or alternating copolymerization are described. While inactive to crosslinking when treated at high temperature ... 
PeroxideCurable Macromonomer Derivatives of IsobutyleneRich Elastomers
(20140130)Macromonomers bearing oligomerizable C=C functionality have been prepared by the nucleophilic displacement of allylic bromide functionality on brominated poly(isobutylenecoisoprene) (BIIR). Whereas commercial grades of ...
