A Predictive Fuzzy-Neural Autopilot For The Guidance Of Small Motorised Marine Craft, Ralph Richter Jan 2000

A Predictive Fuzzy-Neural Autopilot For The Guidance Of Small Motorised Marine Craft, Ralph Richter

School of Engineering, Computing and Mathematics Theses

This thesis investigates the design and evaluation of a control system, that is able to adapt quickly to changes in environment and steering characteristics. This type of controller is particularly suited for applications with wide-ranging working conditions such as those experienced by small motorised craft. A small motorised craft is assumed to be highly agile and prone to disturbances, being thrown off-course very easily when travelling at high speed 'but rather heavy and sluggish at low speeds. Unlike large vessels, the steering characteristics of the craft will change tremendously with a change in forward speed. Any new design of autopilot …

Leveraging Analysis Operators In Incremental Generation, Deryle W. Lonsdale Jan 2000

Leveraging Analysis Operators In Incremental Generation, Deryle W. Lonsdale

Faculty Publications

This paper discusses the integration of an operator-based generation component with a similarly-designed natural-language comprehension system. It begins by sketching the cognitive theory and modeling system that frame both systems. A brief summary of the comprehension system and its characteristics follows, including the relevant operators. The generation system with its own operators and processing stages is then introduced. The degree to which these two systems exhibit shared functionality is then explored, and ongoing work is mentioned.

Solid-State 13c Nmr Characterization Of Matched Tars And Chars From Rapid Coal Devolatilization, Steven T. Perry, Eric M. Hambly, Thomas H. Fletcher, Mark S. Solum, Ronald J. Pugmire Jan 2000

Solid-State 13c Nmr Characterization Of Matched Tars And Chars From Rapid Coal Devolatilization, Steven T. Perry, Eric M. Hambly, Thomas H. Fletcher, Mark S. Solum, Ronald J. Pugmire

Faculty Publications

Matched tar/char sets were prepared by pyrolysis of a lignite and a bituminous coal in two entrained flow reactors at temperatures between 900 K and 1650 K and heating rates of 104–105 K/s. Detailed chemical structural characterization of these tars and chars was performed using elemental analysis and solid-state 13C NMR. This is the first set of detailed solid-state 13C nuclear magnetic resonance (NMR) data on coal tar samples. The average aromatic cluster sizes of the primary tars from these experiments are quite similar to those of their parent coals, confirming an assumption often made …

Modeling High Pressure Char Oxidation Using Langmuir Kinetics With An Effectiveness Factor, Jianhui Hong, William C. Hecker, Thomas H. Fletcher Jan 2000

Modeling High Pressure Char Oxidation Using Langmuir Kinetics With An Effectiveness Factor, Jianhui Hong, William C. Hecker, Thomas H. Fletcher

Faculty Publications

The global nth order rate equation has been criticized for lack of theoretical basis and has been shown to be inadequate for modeling char oxidation rates as a function of total gas pressure. The simple Langmuir rate equation is believed to have more potential for modeling high pressure char oxidation. The intrinsic Langmuir rate equation is applied to graphite flake oxidation data and agrees well with reaction rates at three temperatures over the entire range of oxygen pressure (1–64 atm). It also explains the change of reaction order with temperature. In this work, the intrinsic Langmuir rate equation is combined …

Measurement Of Soot And Char In Pulverized Coal Fly Ash, John M. Veranth, Thomas H. Fletcher, David W. Pershing, Adel F. Sarofim Jan 2000

Measurement Of Soot And Char In Pulverized Coal Fly Ash, John M. Veranth, Thomas H. Fletcher, David W. Pershing, Adel F. Sarofim

Faculty Publications

The unburned carbon in the fly ash produced by low-NOx pulverized coal combustion has been shown by electron microscopy to be a mixture of porous coal char particles and aggregates of submicron particles, which are thought to be soot. The carbon is bimodally distributed with large soot aggregates mixed with the char in the particles larger than 10 microns and dispersed soot found with the submicron particles. A method for determining the mass of soot and char by liquid-suspension gravity separation was used with both laboratory-scale and power plant fly ash samples. For low-NOx, staged, pilot-scale combustion of bituminous coal …

The Use Of Two Mixture Fractions To Treat Coal Combustion Products In Turbulent Pulverized-Coal Flames, Daniel V. Flores, Thomas H. Fletcher Jan 2000

The Use Of Two Mixture Fractions To Treat Coal Combustion Products In Turbulent Pulverized-Coal Flames, Daniel V. Flores, Thomas H. Fletcher

Faculty Publications

Previous coal combustion models using assumed-shape PDF's to treat turbulence-chemistry interactions have used only one progress variable to treat products from coal reactions. This assumes that the products of all coal reactions have the same composition. However. the composition of the combustion products of coal particles is known to vary with burnout, especially between devclatilization and char oxidation. In this work, two progress variables were implemented which distinguish between the products of devolatilization and those of char oxidation. This new approach requires as input the specified volatile content and elemental release during devolatilization. The values for these parameters were estimated …

An Investigation Of The Effects Of Subthalamic Nucleus Stimulation On Acoustic Measures Of Voice, Christopher Dromey, Rajeev Kumar, Anthony E. Lang, Andres M. Lozano Jan 2000

An Investigation Of The Effects Of Subthalamic Nucleus Stimulation On Acoustic Measures Of Voice, Christopher Dromey, Rajeev Kumar, Anthony E. Lang, Andres M. Lozano

Faculty Publications

Summary: Seven patients with Parkinson’s disease were implanted with deep brain stimulators to provide chronic electrical stimulation to the subthalamic nucleus bilaterally. Acoustic recordings and neurologic assessments were undertaken before surgery in the medication-off and medication-on conditions and after surgery with and without electrical stimulation in the medication off and medication-on conditions. The data showed significant improvements in limb motor performance in response to medication before surgery and when the subthalamic nucleus was stimulated after surgery. Six months after surgery, there were small but statistically significant increases in sound pressure level and fundamental frequency variability in response to stimulation in …

The Sanctity Of Association: The Corporation And Individualism In American Law, Liam Seamus O'Melinn Jan 2000

The Sanctity Of Association: The Corporation And Individualism In American Law, Liam Seamus O'Melinn

San Diego Law Review

American society and law display a deep reverence for the group, as long as it assumes corporate or quasi-corporate form. This reverence is not fleeting; rather, it has deep historical roots. In fact, it was there before the republic came into being and it played a profound role in the founding of the nation. Moreover, these roots are not only traditional, but philosophical and religious as well. This Article explores those roots, with three goals in mind. First, to correct the mistaken notion that American law has historically demonstrated a commitment to the individual at the expense of the group, …

"Waive" Goodbye To Tort Liability: A Proposal To Remove Paternalism From Product Sales Transactions, Richard C. Ausness Jan 2000

"Waive" Goodbye To Tort Liability: A Proposal To Remove Paternalism From Product Sales Transactions, Richard C. Ausness

San Diego Law Review

This Article argues that waivers of tort liability should be permitted in connection with product sales. Currently, sellers cannot limit their liability under tort law for personal injuries caused by defective products even though such waivers are allowed, albeit reluctantly, under principles of negligence and warranty law.

Alternative Liability In Litigation Malpractice Actions: Eradicating The Last Resort Of Scoundrels, Lawrence W. Kessler Jan 2000

Alternative Liability In Litigation Malpractice Actions: Eradicating The Last Resort Of Scoundrels, Lawrence W. Kessler

San Diego Law Review

The legal malpractice tort, however, has managed to withstand the winds of legal change. Particularly crucial has been the refusal to apply alternative causation doctrines. The refusal to apply causation doctrines that have been embraced in other areas has significant social effects. As a result, the consumers of legal services receive less protection from the courts than do the consumers of products or medical services.

The Brandeis Legacy, Mary Murphy Schroeder Jan 2000

The Brandeis Legacy, Mary Murphy Schroeder

San Diego Law Review

Louis Brandeis was the greatest lawyer of the early twentieth century, and perhaps of the entire century. He was brilliant, driven, charismatic, and absolutely devoted to improving the lives of the common people of the United States. Put in more contemporary terms, he was committed to the notion that technological and economic advances should not widen the gap between the haves and the have-nots. His causes were the environment, citizenship, freedom of expression, quality of life in the workplace, protection against increasing power wielded by large corporations, and protection of individual privacy. All were issues that emerged at the beginning …

Toward A Theory Of Regulatory Takings For Intellectual Property: The Path Left Open After College Savings V. Florida Prepaid, Shubha Ghosh Jan 2000

Toward A Theory Of Regulatory Takings For Intellectual Property: The Path Left Open After College Savings V. Florida Prepaid, Shubha Ghosh

San Diego Law Review

This Article argues that an infringement of intellectual property rights by a state government constitutes a regulatory taking, requiring compensation to the intellectual property owner. The regulatory takings doctrine is a controversial one. Almost everyone agrees that if a state government physically takes property from its citizens, the government should compensate the owners. Nevertheless, the proposition that state regulation of its citizens' property requires compensation is not as easy to endorse. All regulation affects property in some way, either by reducing its value or by limiting its use. A requirement of compensation could potentially cripple the functioning of state governments. …

Theories Of Areas Of Law, Michael Moore Jan 2000

Theories Of Areas Of Law, Michael Moore

San Diego Law Review

The topic of this symposium is "theories and the law." Since this is such an enormously broad topic, the first thing to do is to narrow it a bit. As I shall discuss it, the topic is not on the central topic of jurisprudence, which is the theory of law. My topic is theories within our law, rather than theories about the nature of law in general. Often we call such theorizing internal to the law we have, "internal jurisprudence," to be contrasted with an "external jurisprudence" that is about law as such. Within internal jurisprudence, there is still considerable …

Dropping Slugs In The Celestial Jukebox: Congressional Enabling Of Digital Music Piracy Short-Changes Copyright Holders Jan 2000

Dropping Slugs In The Celestial Jukebox: Congressional Enabling Of Digital Music Piracy Short-Changes Copyright Holders

San Diego Law Review

In response to the myriad new methods of copying that are emerging from the ongoing digital revolution, Congress has enacted several amendments to copyright law.' These statutes have sought to protect copyright holders in the digital age without chilling the development of new technologies or interfering with consumer access to copyrighted works. Specifically, the Audio Home Recording Act of 1992 ("AHRA") recognized the tremendous potential for piracy created by consumer access to digital audio recording devices. The purpose of the AHRA is not only to prevent infringing acts, but also to compensate copyright holders for the inevitable instances of illicit …

Limaria Hians (Mollusca: Limacea): A Neglected Reef-Forming Keystone Species, J. M. Hall-Spencer, P. G. Moore Jan 2000

Limaria Hians (Mollusca: Limacea): A Neglected Reef-Forming Keystone Species, J. M. Hall-Spencer, P. G. Moore

School of Biological and Marine Sciences

1. The case is made for recognition of the marine bivalve Limaria hians as a reef-forming species, which plays a key architectural role in certain benthic communities around the United Kingdom and Ireland. 2. This species uses byssal threads to construct nests that can coalesce to form reefs that cover hectares of seabed, contain multiple conspecifies and bind sediment. In so doing, L. hians modifies physical, chemical and biological processes at the sediment-water interface. 3. Such nests support a high diversity of associated organisms in coarse-grade sediments (19 species of algae and 265 species of invertebrates from six discrete nests …
