MultiLevel Optimal Design Using Game Theory With Model Updating By Low Discrepancy Sampling, Yanchen Xu
MultiLevel Optimal Design Using Game Theory With Model Updating By Low Discrepancy Sampling, Yanchen Xu
Theses and Dissertations
The Design of Experiment (DOE) based response surface methodology (RSM) is a commonly used technique for solving optimization problems. The traditional DOE method has some shortcomings when used to update the RSM model. This thesis aims to develop a new DOE technique to solve the model updating problems in design optimization. Toward this end, a new DOE based RSM method is proposed to solve this problem by using lowdiscrepancy sequence method to generate the additional data points needed to update the model to replace the traditional factor and level based DOE method.

Phase Dynamics Of Locset Control Methodology, Brendan Neschke
Masters Theses
Singlemode fiber amplifiers produce diffractionlimited beams very efficiently. Maximum beam intensity requires that an array of these amplifiers have their beams coherently combined at the target. Optical path differences and noise adversely affect beam quality. An existing closed loop phase control methodology, called the locking of optical coherence by singledetector electronicfrequency tagging (LOCSET), corrects phase errors in real time by electronically detecting path length differences and sending signals to lithium niobate phase adjusters. Broadening the linewidth using “jitter” of the input signal can increase the output power of an individual amplifier by suppressing nonlinearity. The system dynamics of LOCSET are ...
Time Integration Methods Of Fundamental Solutions And Approximate Fundamental Solutions For Nonlinear Elliptic Partial Differential Equations, Corey Leon Jones
Time Integration Methods Of Fundamental Solutions And Approximate Fundamental Solutions For Nonlinear Elliptic Partial Differential Equations, Corey Leon Jones
Dissertations
A timedependent method is coupled with the Method of Approximate Particular Solutions (MAPS) of Deltashaped basis functions, the Method of Fundamental Solutions (MFS), and the Method of Approximate Fundamental Solutions (MAFS) to solve a second order nonlinear elliptic partial differential equation (PDE) on regular and irregular shaped domains. The nonlinear PDE boundary value problem is first transformed into a timedependent quasilinear problem by introducing a fictitious time. Forward Euler integration is then used to ultimately convert the problem into a sequence of timedependent linear nonhomogeneous modified Helmholtz boundary value problems on which the superposition principle is applied to split the ...
Phase Field Approach For Multiphase Phase Transformations, Twinning, And VariantVariant Transformations In Martensite, Arunabha Mohan Roy
Phase Field Approach For Multiphase Phase Transformations, Twinning, And VariantVariant Transformations In Martensite, Arunabha Mohan Roy
Graduate Theses and Dissertations
New advanced phase field model of transformations between martensitic variants and multiple twinning within martensitic variants is developed for large strains and lattice rotations. It resolves numerous existing problems. The model, which involves just one order parameter for the description of each variantvariant transformation and multiple twinnings within each martensitic variant, provides a wellcontrolled description of variantvariant transformations and multiple twinning, including expressions for interface tension which are consistent with the sharp interface limit. The finite element approach is developed and applied to the solution of a number of examples of twinning and combined austenitemartensite and martensitemartensite phase transformations (PTs ...

Correctness Results For OnLine Robust Principal Components Analysis, Brian Thomas Lois
Graduate Theses and Dissertations
This work studies two interrelated problems  online robust PCA (RPCA) and online lowrank matrix completion (MC). In recent work by Candes et al., RPCA has been defined as a problem of separating a lowrank matrix (true data), L:=[ℓ₁, ℓ₂, ... ℓt, ... , ℓtmax and a sparse matrix (outliers), S:=[x₁, x₂, ... xt, ..., xtmax] from their sum, M:=L+S. Our work uses this definition of RPCA. An important application where both these problems occur is in video analytics in trying to separate sparse foregrounds (e.g., moving objects) and slowly changing backgrounds.
While there has been a large amount of recent ...

Parameters Estimation Of Material Constitutive Models Using Optimization Algorithms, Kiswendsida Jules Kere
Williams Honors College, Honors Research Projects
Optimization Algorithms are very useful for solving engineering problems. Indeed, optimization algorithms can be used to optimize engineering designs in terms of safety and economy. Understanding the proprieties of materials in engineering designs is very important in order to make designs safe. Materials are not really perfectly homogeneous and there are heterogeneous distributions in most materials. In this paper, SelfOPTIM which is an inverse constitutive parameter identification framework will be used to identify parameters of a linear elastic material constitutive model. Data for SelfOPTIM will be obtained using ABAQUS simulation of a dogbone uniaxial test. Optimization Algorithms will be used ...

The Simulation & Evaluation Of Surge Hazard Using A Response Surface Method In The New York Bight, Michael H. Bredesen
UNF Graduate Theses and Dissertations
Atmospheric features, such as tropical cyclones, act as a driving mechanism for many of the major hazards affecting coastal areas around the world. Accurate and efficient quantification of tropical cyclone surge hazard is essential to the development of resilient coastal communities, particularly given continued sea level trend concerns. Recent major tropical cyclones that have impacted the northeastern portion of the United States have resulted in devastating flooding in New York City, the most densely populated city in the US. As a part of national effort to reevaluate coastal inundation hazards, the Federal Emergency Management Agency used the Joint Probability Method ...

Synchronization Of Bistatic Radar Using Chaotic Amplitude And Frequency Modulated Signals, Chandra Sekhar Pappu
Open Access Theses & Dissertations
The purpose of this work is to develop a synchronization scheme for bistatic radar that uses a 3D chaotic system to generate and process wideband AM and FM signals, which allows for the extraction of high rangeresolution information from targets. For AM bistatic radar, the setup includes a drive oscillator at the transmitter and a response oscillator at the receiver. The challenge is synchronizing the response oscillator to the drive oscillator with a scaled version of the transmitted signal sr(t, x) = αs t(t, x), where x is a chaotic state variable and α is a scaling factor. Here ...
Modeling, Optimization, And Sensitivity Analysis Of A Continuous MultiSegment Crystallizer For Production Of Active Pharmaceutical Ingredients, Bradley James Ridder
Modeling, Optimization, And Sensitivity Analysis Of A Continuous MultiSegment Crystallizer For Production Of Active Pharmaceutical Ingredients, Bradley James Ridder
Open Access Dissertations
We have investigated the simulationbased, steadystate optimization of a new type of crystallizer for the production of pharmaceuticals. The multisegment, multiaddition plugflow crystallizer (MSMAPFC) offers better control over supersaturation in one dimension compared to a batch or stirredtank crystallizer. Through use of a population balance framework, we have written the governing model equations of population balance and mass balance on the crystallizer segments. The solution of these equations was accomplished through either the method of moments or the finite volume method. The goal was to optimize the performance of the crystallizer with respect to certain quantities, such as maximizing the ...
