Biped Dynamic Walking Using Reinforcement Learning, Hamid Benbrahim

Doctoral Dissertations

This thesis presents a study of biped dynamic walking using reinforcement learning. A hardware biped robot was built. It uses low gear ratio DC motors in order to provide free leg movements. The Self Scaling Reinforcement learning algorithm was developed in order to deal with the problem of reinforcement learning in continuous action domains. A new learning architecture was designed to solve complex control problems. It uses different modules that consist of simple controllers and small neural networks. The architecture allows for easy incorporation of modules that represent new knowledge, or new requirements for the desired task. Control experiments were …

Analysis And Design Of Ac Induction Motors With Squirrel Cage Rotors, Shine Ho

Doctoral Dissertations

The traditional approach to modelling the AC induction motor revolves around the well-known equivalent "T" circuit model. In this approach, the direct connection from geometry to performance is suppressed. For better understanding of magnetic, electrical, and thermal behaviors, three lumped models based on the actual geometry are developed in this dissertation. Based on these lumped models, an iterative design model is also developed.

In order to analyze and design induction motors, the relationships of basic motor variables to motor performance must be known. For determining the relationships, three new mathematical lumped models are developed. The magnetic model describes flux behavior. …

Pilot-Scale Solvent Sublation For The Removal Of Hydrophobic Compounds From Wastewaters., Jeffrey Scott Smith

LSU Historical Dissertations and Theses

Solvent sublation is a nonfoaming adsorptive bubble process which exploits the surface active nature of organic compounds in their removal from aqueous systems. Gas bubbles are introduced into an aqueous media and are buoyed upward to an immiscible organic solvent. As the bubbles rise, organic materials are selectively adsorbed from the aqueous phase and transported to the overlying, quiescent solvent layer. This dissertation studied three-phase, continuous solvent sublation of pyrene and pentachlorophenol from simulated wastewater at the pilot-scale. Steady-state removal efficiencies as high as 96% for pyrene and 94% for pentachlorophenol were demonstrated and were significantly greater than the corresponding …

Longitudinal Dispersion And Interstitial Velocity Relationship In Subsurface Flow Constructed Wetlands., Gianna M. Cothren

LSU Historical Dissertations and Theses

Treatment of municipal and rural wastewater using subsurface flow constructed wetlands (SFCW's) is growing in popularity. These systems often consist of an excavated cell containing 2-3 in. rock with the wastewater level maintained below the media surface. A SFCW is a natural form of wastewater treatment which removes organics and nutrients based on the attached growth of microorganisms on crushed rocks where biological reactions take place. The currently accepted design procedure is based on the first order plug flow model, although tracer studies have shown that flow conditions are not well represented by the plug flow condition. This design rationale …

Tertiary Recovery Of Oil By Up-Dip Gas Injection., Tammy Theresa Bourgoyne

LSU Historical Dissertations and Theses

A tertiary gas injection process denotes the mobilization of waterflood residual oil by gas invasion; whereas, secondary gas injection denotes the displacement of a continuous oil phase by gas. The term up-dip gas injection implies that the gas is injected in the crest of the structure in order to displace fluid down-dip where it can be recovered in a production well; whereas, an attic oil recovery process usually implies a cyclic injection/recovery process using a single well. The objective of this study is to develop a technique for modelling relative permeability in a tertiary gas injection process occurring in a …

On-Line Steady-State Gain Identification For On-Line Optimization Of Multivariable Constrained Chemical Processes., Umesh Kishore Chitnis

LSU Historical Dissertations and Theses

The Amoco Model IV Fluidized Catalytic Cracking Unit (FCCU) (McFarlane et al, 1993) was augmented with Lee & Groves Model (1985) to provide for a simple but realistic product distribution model. This enabled a better and realistic on-line optimization of the FCCU. A Supervisory Multivariable Constrained Optimization (SMCO) algorithm was applied to this augmented model. It was observed that the FCC unit is optimized successfully, without violating any constraints. The parabolic error-penalizing function, incorporated in the algorithm allowed the constraints to asymptotically approach the limits without violating them. The on-line optimization to FCC unit led to maximizing of the feeds, …

Improved Method For Selecting Kick Tolerance During Deepwater Drilling Operations., Shiniti Ohara

LSU Historical Dissertations and Theses

One of the most critical aspects in the design of oil and gas wells is the selection of the depths at which steel casing is set. As the length of open borehole increases, the risk of formation fracturing during drilling operations increases. Formation fracture often leads to an underground blowout that can be very expensive to control. Because of the special problems involved in drilling deepwater well, accurately measuring the risk of formation fracture is essential. A calculated parameter called "kick tolerance" is often used to measure this risk. In this study, improved computer software specifically designed for computing kick …

A Hierarchical Approach To Equilibrium Cycle Nuclear Fuel Analysis., Jon Juneau

LSU Historical Dissertations and Theses

This research involved developing an expert system that allows a nuclear fuel engineer to quickly provide answers to strategic nuclear fuel management questions, which are typically broad based. Current nuclear fuel analysis research concentrates on getting more accurate and precise answers at the expense of using large computer programs to get answers that are too specific to answer the broad based questions. The expert system brings together several artificial intelligence techniques to allow a nuclear fuel engineer to consider several scenarios in a general way in order to quickly answer the fuel management questions asked. The expert system is based …

Use Of Geographic Information System Technology To Assess Vulnerability To Shallow Groundwater Contamination., Brenda G. Bruner

LSU Historical Dissertations and Theses

Geographic Information System (GIS) technology was used to develop a local scale screening procedure for assessing shallow ground water's vulnerability to nitrate contamination. The procedure was based on the spatial distribution of ten key physical and chemical properties of soils. Both flow characteristics and attenuation capabilities of soils were incorporated into the assessment. Land surface areas were classified by the GIS to show the level of vulnerability present at a site as a result of existing natural conditions. The procedure produced a Vulnerability Index (VI), and resulted in VI ranging from 4.98 to 6.72 for the study area (with ten …

Neuro-Fuzzy Models For Classification And Rule Generation., Sushmita Mitra Dr.

Doctoral Theses

Machine recognition [1, 2] of patterns can be viewed as a two-fold task, consisting of learning the invariant and common properties of a set of samples characterizing a class, and of deciding a new sample as a possible member of the class by noting that it has properties common to those of the set of samples. In other words, pattern recognition by computers can be described as a transformation from the measurenment space M to the feature space F and finally to the decision space D (1), i.e., M ⟶F⟶D.Here, the mapping 6 : F⟶D is the decision function and …

On Detection And Use Of Reflectional Symmetry In Computer Vision., Dipti Prasad Mukherjee Dr.

Doctoral Theses

The problems of detection and use of reflectional symmetry in the images of planar shape contours are studied. Symmetry, in general, provides important shape representation cues, some of which we utilise here, to acquire viewpoint information and, towards model based shape matching. We concentrate on local reflectional symmetries of emoothly curved planar objecta, though the methoda are equally applicable to polygonal objects; even this could be extended to certain three-dimensional shapes and for other object relations such as rotational symmetry.Under the affine or perspective approximation to image projection, properties of geometrie invariance are used to find (reflectional) symmetric contour pairs. …

The methods used to perform the analyses in the environmental impact statement have been refined in the time since the environmental assessment was prepared. This occurred partly because of the larger number of naval spent nuclear fuel assemblies analyzed and the wider scope of sites and methods of storage to be evaluated, and partly because additional time was available to implement the refinements. In addition to refinements in the methods for performing the calculations, some minor changes in the calculational models were made in order to establish a high degree of consistency with the analytical methods used for the other …

Per U.S. Environmental Protection Agency's guidance, each contaminant was categorized as carcinogenic or noncarcinogenic. Exposures to contaminants were then evaluated for potential health effects. The method used was dependent on whether the exposure was to the public or to a worker and whether the contaminant was classified as a carcinogen or a noncarcinogen. Health effects were reported separately and were not summed where distinctly different types of effects were reported for chemical exposures (that is, carcinogenic and noncarcinogenic).
