Proper Orthogonal Decomposition Based Optimal Control Design Of Heat Equation With Discrete Actuators Using Neural Networks, Radhakant Padhi, S. N. Balakrishnan

Mechanical and Aerospace Engineering Faculty Research & Creative Works

A new method is presented for the optimal control design of one-dimensional heat equation with the actuators being concentrated at discrete points in the spatial domain. This systematic methodology incorporates the advanced concept of proper orthogonal decomposition for the model reduction of distributed parameter systems. After deigning a set of problem-oriented basis functions an analogous optimal control problem in the lumped domain is formulated. The optimal control problem is then solved in the time domain, in a state feedback sense, following the philosophy of adaptive critic neural networks. The control solution is then mapped back to the spatial domain using …

A Quantitative Similarity Metric For Design-By-Analogy, Daniel A. Mcadams, Kristin L. Wood

Mechanical and Aerospace Engineering Faculty Research & Creative Works

During the design and development of new products, design engineers use many techniques to generate and define new and "good" concepts. Inherent in this search for solutions is the conscious and unconscious reliance on prior experience and knowledge, or design-by-analogy. In this paper, a quantitative metric for design-by-analogy is developed. This metric is based on the functional similarity of products. By using this product-similarity metric, designers are able to formalize and quantify design-by-analogy techniques during concept and layout design. The methods, as developed in this paper, allow a designer with limited experience to develop sophisticated solutions that enhance the overall …

A Functional Basis For Engineering Design: Reconciling And Evolving Previous Efforts, Julie Hirtz, Robert B. Stone, Daniel A. Mcadams, Simon Szykman, Kristin L. Wood

Mechanical and Aerospace Engineering Faculty Research & Creative Works

In engineering design, all products and artifacts have some intended reason behind their existence: the product or artifact function. Functional modeling provides an abstract, yet direct, method for understanding and representing an overall product or artifact function. Functional modeling also strategically guides design activities such as problem decomposition, physical modeling, product architecting, concept generation, and team organization. A formal function representation is needed to support functional modeling, and a standardized set of function-related terminology leads to repeatable and meaningful results from such a representation. We refer to this representation as a functional basis; in this paper, we seek to reconcile …

Ethnography And The Idealized Accounts Of Science In Law, David S. Caudill

San Diego Law Review

n Part I, I confirm the idealizations of science in law and their implications for legal scholarship and practice. In Part II, I describe the ethnographic method used by science studies scholars, with reference to my own ethnographic analysis of interviews with three neuroscientists. I conclude Part II by identifying various social aspects of science that comprise a complex picture of scientific activity. In Part ill, I discuss the implications of ethnomethodology for trial practice, including deposition analysis, Daubert-type hearings, cross-examination techniques, and drafting jury instructions. Part IV addresses anticipated criticisms of my arguments.

The Purloined Personality: Consumer Profiling In Financial Services

San Diego Law Review

Although almost every sector of the U.S. economy practices consumer profiling,perhaps the most substantive challenge to consumer privacy is found in the activities surrounding the use and disclosure of consumer transaction data by the financial services industry. For that reason, this Comment focuses exclusively on consumer profiling in the context of the financial services sector, defined as banks, credit card issuers, brokerages, and insurance companies.

Motion Based Event Recognition Using Hmm, Gu Xu, Yu-Fei Ma, Hong-Jiang Zhang, Shiqiang Yang

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Motion is an important cue for video understanding and is widely used in many semantic video analyses. We present a new motion representation scheme in which motion in a video is represented by the responses of frames to a set of motion filters. Each of these filters is designed to be most responsive to a type of dominant motion. Then we employ hidden Markov models (HMMs) to characterize the motion patterns based on these features and thus classify basketball video into 16 events. The evaluation by human satisfaction rate to classification result is 75%, demonstrating effectiveness of the proposed approach …

Proper Orthogonal Decomposition Based Feedback Optimal Control Synthesis Of Distributed Parameter Systems Using Neural Networks, Radhakant Padhi, S. N. Balakrishnan

Mechanical and Aerospace Engineering Faculty Research & Creative Works

A new method for optimal control design of distributed parameter systems is presented in this paper. The concept of proper orthogonal decomposition is used for the model reduction of distributed parameter systems to form a reduced order lumped parameter problem. The optimal control problem is then solved in the time domain, in a state feedback sense, following the philosophy of ''adaptive critic'' neural networks. The control solution is then mapped back to the spatial domain using the same basis functions. Numerical simulation results are presented for a linear and nonlinear one-dimensional heat equation problem in an infinite time regulator framework.

Three-Dimensional Micromachined On-Chip Inductors For High Frequency Applications, Nimit Chomnawang

LSU Doctoral Dissertations

Demands for wireless communication are ever-escalating for consumer and military communication applications. The requirements of portability, more functionality and lower cost have been driving forces toward smaller, more sophisticated and flexible wireless devices with lower power consumption. To meet these requirements, monolithically integrated passive inductors with high Q-factors and high self-resonant frequencies are desirable. Q-factor and self-resonant frequency of an inductor are significantly degraded at high frequencies due to conductor ohmic loss, magnetically induced eddy current in the conductive substrate, and lower self-resonant frequency from capacitance between conductive substrate and conductors.
In this dissertation, novel three-dimensional arch-like solenoid and dome-shaped …

Incorporating Aspects Into The Software Development Process In Context Of Aspect-Oriented Programming, Mark Alan Basch

UNF Graduate Theses and Dissertations

Aspect-oriented programming is a relatively new approach to programming that is design to resolve issues of separation of concerns. Rather than focusing on commonality of objects, as in object-oriented programming, aspect –oriented programming focuses on commonality of concerns, or more precisely as described by experts in the field, of "cross-cutting concerns." These are aspects that cut across different modules of a program, such as security and authentication issues.

While much research in the area has focused on developing programming languages, little attention has been given to dealing with aspects in the software development process and the Unified Modeling Language. This …

Defining Imaginary Audience Scores Via Gender Attributes Versus Biological Gender, George M. Freeman

UNF Graduate Theses and Dissertations

Imaginary audience scores for males and females have not demonstrated consistent differences in the literature. In this study, scores on the Imaginary Audience Scale (lAS) and on the Imaginary Audience subscale of the Adolescent Egocentrism-Sociocentrism scale (ABS) were compared to self-rating of gender attributes on the Personality Attributes Questionnaire (PAQ). Results for 64 females and 32 males surveyed at a southeastern university indicate that one's self-rating of gender attributes correlates with imaginary audience scores while biological gender does not. As masculine attribute scores increase, lAS scores and Abiding Self subscale scores decrease. As masculine-feminine attribute scores (traits favored by both …

How Theology Might Learn From Law (Symposium: The Theology Of The Practice Of Law), James Boyd White

Articles

I want to start today with an account of the way lawyers think and speak, and then ask whether it might be useful for the theologically minded to take these practices and procedures seriously as a ground of comparison from which to look at their own. In doing this I shall look at the practice of law with an emphasis not on its social effects or ethical difficulties but on the nature of the activity itself, viewed from the inside, asking in particular what kind of knowledge it requires and creates in its practitioner. What does the lawyer learn from …

Graphite Platelet Nanostructures, Marian Mazurkiewicz

Mining Engineering Faculty Research & Creative Works

Separated graphite nanostructures are formed of thin graphite platelets having an aspect ratio of at least 1,500:1. The platelets have an angular geometric structure and may be fully independent from an original graphite particle, or partially attached to the particle. The graphite platelets have an average thickness in the range of 1-100 nm. The graphite nanostructures are created from synthetic or natural graphite using a high-pressure mill. Fluid jets of the high-pressure flaking mill cause fluid to enter the tip of cracks in the graphite particles, which creates tension at the tip. This tension causes the cracks to propagate along …

The Causes Of Armature Surface Fracturing Within Helical Flux-Compression Generators, Jason Baird, Paul Nicholas Worsey

Mining Engineering Faculty Research & Creative Works

Aluminum and copper tubes filled with explosive were tested during this study of high strain rate effects, as an adjunct to helical flux-compression generator research at the University of Missouri-Rolla, directly affecting the understanding of flux cutoff and high strain-rate changes in generator armatures. Longitudinal cracks characteristically developed in the outer surface of armatures at a smaller expansion ratio than predicted. These cracks occurred within two diameters of the detonator end of the armature but did not extend when the tubing expanded under explosive pressurization. Such cracks appear to cause magnetic flux cutoff, and flux losses seriously affect energy conversion …

Performance Of Fisheries Sector Planning In Bangladesh, S Rahman, Kk Ahmed

School of Geography, Earth and Environmental Sciences

The overall planning performance of the fisheries sector in Bangladesh over the past three decades was evaluated. Performance has been unsatisfactory largely due to contiguous overestimation of the planning targets and the existence of serious financial, technological, institutional and social constraints. Despite the remarkable growth in export earnings and a stable GDP contribution of 3.2–5.6%, budget allocations remained extremely low (0.7–1.4% of total outlay) in subsequent plan periods. Production from marine fisheries performed satisfactorily with slow growth in recent years, while inland fisheries with initial poor performance showed improvements from the mid-1980s owing to increased productivity in culture fisheries, particularly …

Evaluating And Monitoring Nucleation And Growth In Copper Foil, Ye Kun Lee, Thomas J. O'Keefe

Materials Science and Engineering Faculty Research & Creative Works

The electrodeposition of copper foil for use in electronic materials applications is a complex and demanding process. The specific aspects of producing and controlling the structure-property-performance requirements of the foil are important because of the stringent demands placed on their use in printed circuit boards and similar products. In this paper, a brief review of the electrodeposition process for raw copper foil is presented. Since electrolyte additives play such a significant role in the copper-deposition process, the effects of two essential additives, chloride ion and an organic (e.g., glue or gelatine), on the foil are described. Also, the influence of …
