A reduced-turbulence, reduced-entrainment electrostatic precipitator
This thesis describes testing of an electrostatic precipitator that has a portion of the main precipitator flow drawn through a porous (fabric) collecting surface. Tests investigated effects of flow through the collecting surface (side flow) on precipitator turbulence and particulate removal …

Reduced-Encoding Dynamic Imaging
… dynamic information. The two-reference reduced-encoding imaging by generalized-series reconstruction (TRIGR) method suppresses background information through the use of a second high-resolution reference image. A second technique injects information from the dynamic data into the GS …

Reduced-order adaptive control
… the results are applied to the use of PLID as a reduced-order system estimator. A self-tuning regulator (STR) is constructed using PLID and the effects of reducing the expected order of the system are demonstrated. A second adaptive control algorithm is presented wherein the STR controller is …

Mathematical Achievement in Reduced Stress
<p>The study, Mathematical Achievement in Reduced Classes, evaluated qualitative data on how class size effects student achievement in math. The information was collected by interviewing teachers on their experiences of teaching multiplication in a reduced or regular class size. Two groups of …

Global optimization in reduced space
… problem dimension. This leads to the notion of reduced-space problem formulations where either the number of variables that the algorithm branches on is reduced or only the actual degrees of freedom are visible to the optimization algorithms, following a partition of the variables into …

The combinatorics of reduced decompositions
This thesis examines several aspects of reduced decompositions in finite Coxeter groups. Effort is primarily concentrated on the symmetric group, although some discussions are subsequently expanded to finite Coxeter groups of types B and D. In the symmetric group, the combined frameworks of …

Lignin biodegradation: reduced oxygen species
… the macromolecule. The possible involvement of reduced oxygen species produced by white-rot fungi in the initial breakdown of the lignin macromolecule, during its biodegradation, was investigated. Using Coriolus versicolor as a representative of white-rot fungi, I demonstrated that C. versicolor …

Approximate Deconvolution Reduced Order Modeling
This thesis proposes a large eddy simulation reduced order model (LES-ROM) framework for the numerical simulation of realistic flows. In this LES-ROM framework, the proper orthogonal decomposition (POD) is used to define the ROM basis and a POD differential filter is used to define the large ROM …

Nutritional evaluation of conventional, high protein, reduced fiber, and reduced phosphorus corn co-products for poultry
… protein (CFP), high protein-DDGS (HP-DDGS), reduced fiber high protein-DDGS (RFHP-DDGS), and reduced phosphorus-DDGS (RP-DDGS) were evaluated. The precision-fed rooster assay was utilized to measure TMEn and standardized amino acid (AA) digestibility. Corn fermented protein contained an …

Large Eddy Simulation Reduced Order Models
… filtering to develop a large eddy simulation reduced order model (LES-ROM) framework for fluid flows. Proper orthogonal decomposition is utilized to extract the dominant spatial structures of the system. Within the general LES-ROM framework, two approaches are proposed to address the …

THERMOSYPHON FLOODING IN REDUCED GRAVITY ENVIRONMENTS
… on a parabolic flight campaign to achieve the Reduced Gravity Environments (RGE) needed to obtain empirical data for analysis. Current correlation models of Faghri and Tien and Chung do not agree with the data. A new model is presented that predicts the flooding limits for thermosyphons in …

Physical chemistry of microbially-reduced smectites
… less than 0.4 mmol g$\sp{-1}$ than in chemically-reduced smectites. The presence of structural Fe(II) apparently overcomes the opposing effect of organics on the ability of clay gels to retain water. The flow behavior of microbially-reduced smectite suspensions depended on smectite, medium used, …

Reduced order modeling of distillation systems
… separation feasibility is investigated using reduced-order models. Three different models of nonequilibrium rate-based packed distillation columns are developed, each with progressive levels of complexity. The final model is the most complex, and is based on the Maxwell-Stefan theory of mass …

Reduced basis method for Boltzmann equation
… of the problem. The next step is to perform the reduced basis analysis of the equation using these accurate finite element solutions. We conclude the project by verifying that the orthonormal reduced Basis method based on the greedy algorithm converges rapidly over the chosen test space.
