Design Of A Lorentz, Slotless Self-Bearing Motor For Space Applications, Barrett Alan Steele

University of Kentucky Master's Theses

The harsh conditions of space, the stringent requirements for orbiting devices, and the increasing precision pointing requirements of many space applications demand an actuator that can provide necessary force while using less space and power than its predecessors. Ideally, this actuator would be able to isolate vibrations and never fail due to mechanical wear, while pointing with unprecedented accuracy. This actuator has many space applications from satellite optical communications and satellite appendage positioning to orbiting telescopes. This thesis presents the method of design of such an actuator a self-bearing motor. The actuator uses Lorentz forces to generate both torque and …

Investigation Of Soluble Salts On Kentucky Bridges, Sudhir Palle, Rick Younce, Theodore Hopwood Ii

Kentucky Transportation Center Research Report

Invisible soluble salts present on steel highway structures can act to promote corrosion even after maintenance painting. Soluble salts include chloride, nitrate and sulfate ions. Soluble salts found on bridge decks and roadways are the result of usage of deicing salts (chlorides), and the deposition of atmospheric pollution (nitrates and sulfates) on exterior surfaces. Typical pollution-related sources of soluble salts are coal-fired power plants, refineries, farming operations, vehicle emissions, and chemical plants. Sites for soluble salt damage on bridges include:

• Beam ends under open or leaking expansion joints,
• Flanges and lower portions of webs of overpass structures,
• Lower chords and …

Experimental Study Of Heat Transfer From A Moving And Evaporating Meniscus On A Heated Surface, Wai Keat Kuan

Theses

A stable meniscus is formed between a needle dispensing water over a heated circular face of a rotating copper block. The needle is offset from the axis of rotation and thus forms a moving meniscus. The water flow rate, heater surface temperature and the speed of rotation are controlled to provide a stable meniscus with complete evaporation of water without any meniscus break-up. The experimental heat transfer rate is compared with the transient heat conduction model. The results indicate that the transient heat conduction plays a major role in the heat transfer process from a moving meniscus. The study provides …

Carbon Nanotube Catalysts: An Approach Toward Nanodimensional Reactions, Mindy Gordon

Theses

The oxidations of aromatic and aliphatic amines have been investigated to evaluate the catalytic effect of functionalized multiwalled carbon nanotubes. Aniline oxidation by hydrogen peroxide produces very low yields of azoxybenzene; similarly, p-toluidine oxidation produces azoxytoluene after long time periods. When functionalized multiwalled carbon nanotubes are present in these reactions, the above oxidations produced unique products such as azobenzene or azotoluene within a short period. The course of the reaction has been followed by GC/MS that showed a mass number of 198 corresponding to azoxybenzene (without carbon nanotubes) or 182 corresponding to azobenzene (with the nanotubes). The first stage of …

Concept, Design, Simulation, And Fabrication Of An Ultra-Scalable Vertical Mosfet, Keith H. Tabakman

Theses

A new orientation to the conventional MOSFET is proposed. Processing issues, as well as short channel effects have been making planar MOSFET scaling increasingly difficult. It is predicted by the 2001 International Technology Roadmap for Semiconductors (ITRS) that non-planar devices will be needed for production as early as 2007. The device proposed in this thesis is similar in operation to the planar MOSFET, however the current transport from source to drain, normally in the same plane as the wafer surface, is oriented perpendicular to the die surface. The proposed device has successfully been simulated, showing a proof of concept. Fabrication …

Experimental Investigation Of Elemental Incorporation In The Otoliths Of Larval And Juvenile Fish: Implications For Use As Environmental Recorders, Gretchen Bath Martin

Biological Sciences Theses & Dissertations

Innovative techniques for discerning fish stocks, identifying nursery habitats, locating spawning sites, tracing larval transport pathways, and quantifying the degree of population connectivity are required to meet the goals of sustainable management of marine capture fisheries. One of the most promising techniques is the use of elemental signatures in fish otoliths (ear stones), which record valuable life history data and serve as the link between fish and their environment. To validate the assumption that otolith elemental composition is a function of water elemental concentrations, and to address the possible effects of external variables such as temperature and salinity, the composition …

Boussinesq Model And The Relative Trough Froude Number (Rtfn) For Wave Breaking, Takashi Okamoto

Civil & Environmental Engineering Theses & Dissertations

The relative trough Froude number (RTFN) theory is a new phase-resolving type, wave breaking trigger model introduced by Utku (1999) and Utku and Basco (2002). Based on the moving hydraulic jump concept, this model provides a better implementation of wave breaking in terms of hydrodynamics. Development of computer resources permits the use of the phase-resolving type, Boussinesq wave models in nearshore areas. The Boussinesq equation, however, does not include the physics of wave breaking, so that an additional mechanism is required to initiate wave breaking in the model. The main objective of this study is to develop a new wave …

Developing A Methodology To Detect Partial Failures For Dynamic Systems, Anwar A. Al-Jowder

Engineering Management & Systems Engineering Theses & Dissertations

The purpose of this research is to develop a decision support system that can assist in detecting partial failures in dynamic systems such as Fire Control System Tracking Radar (TR) onboard Naval Ships. Partial failures do not necessarily shut down the system immediately but cause degradation of operational performance. Previous work has shown that experts in the field of failure detection, test point insertion and Built-In-Test Equipment (BITE) can provide useful input in detecting partial failures. Partial failures affect operational system performance and support costs, which can be significant. Often, however, partial failure detection consists of the estimations and opinions …

Approximate Dynamic Programming Based Optimal Neurocontrol Synthesis Of A Chemical Reactor Process Using Proper Orthogonal Decomposition, Radhakant Padhi, S. N. Balakrishnan

Mechanical and Aerospace Engineering Faculty Research & Creative Works

The concept of approximate dynamic programming and adaptive critic neural network based optimal controller is extended in this study to include systems governed by partial differential equations. An optimal controller is synthesized for a dispersion type tubular chemical reactor, which is governed by two coupled nonlinear partial differential equations. It consists of three steps: First, empirical basis functions are designed using the "Proper Orthogonal Decomposition" technique and a low-order lumped parameter system to represent the infinite-dimensional system is obtained by carrying out a Galerkin projection. Second, approximate dynamic programming technique is applied in a discrete time framework, followed by the …

Hierarchical Optimal Control Of A Turning Process - Linearization Approach, Anand Dasgupta, B. Pandurangan, Robert G. Landers, S. N. Balakrishnan

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Machining process control technologies are currently not well integrated into machine tool controllers and, thus, servomechanism dynamics are often ignored when designing and implementing process controllers. In this paper, a hierarchical controller is developed that simultaneously regulates the servomechanism positions and cutting forces in a lathing operation. The force process and servomechanism system are separated into high and low levels, respectively, in the hierarchy. The high level goal is to maintain a constant cutting force to maximize productivity while not violating a spindle power constraint. This goal is systematically propagated to the lower level and combined with the low level …

Proper Orthogonal Decomposition Based Modeling And Experimental Implementation Of A Neurocontroller For A Heat Diffusion System, Prashant Prabhat, S. N. Balakrishnan, Dwight C. Look, Radhakant Padhi

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Experimental implementation of a dual neural network based optimal controller for a heat diffusion system is presented. Using the technique of proper orthogonal decomposition (POD), a set of problem-oriented basis functions are designed taking the experimental data as snap shot solutions. Using these basis functions in Galerkin projection, a reduced-order analogous lumped parameter model of the distributed parameter system is developed. This model is then used in an analogous lumped parameter problem. A dual neural network structure called adaptive critics is used to obtain optimal neurocontrollers for this system. In this structure, one set of neural networks captures the relationship …

Recognizing Toxic Species In Aquatic Habitats: A Potential Concern In Lake Management, Mikolaj Kokocinski, Harold G. Marshall

Biological Sciences Faculty Publications

The importance of distinguishing toxic and non-toxic algal species is becoming a more common problem for management decisions associated with various freshwater and estuarine habitats. An example is given where two dinoflagellates, originally unidentified as closely resembling the toxin producing Pfiesteria spp., have been compared to these species. In order to clarify any relationship to Pfiesteria spp., scanning electron microscopy was used to determine the plate tabulation patterns of these dinoflagellates and make comparisons to the tabulation present in Pfiesteria spp. The results indicated significant differences in the plate tabulations of these taxa to distinguish them from Pfiesteria …

Algal Composition And Abundance In The Neuston Surface Micro Layer From A Lake And Pond In Virginia (U.S.A.), Lubomira Burchardt, Harold G. Marshall

Biological Sciences Faculty Publications

A comparative study was conducted that characterized the algae within the neuston, ca 2 mm below the surface, and the algae in the water column from two freshwater habitats. There were significant differences in total algal abundance and the abundance of diatoms, cyanoprokaryotes, and chlorophytes between the neuston and water column algae of these two regions during each season and at both sites. The pond neuston was dominated by chlorophytes, with total algal abundance ranging seasonally from 0.6 to 59.6 x 10^-3 cells ml^-1 compared to water column algal concentrations of 4.1 to 40.4 x 10-3 cells ml-1. …

Temptations To Take: Misappropriation Of Trade Secrets, Damages And Remedies, Eric S. Tautfest

Computer Law Review and Technology Journal

Protecting trade secrets serves two basic functions: it provides a means for preserving standards of commercial ethics and it encourages innovation. In contrast to a patent or a copyright, a trade secret has no statutory limitation and can, conceivably, be protected forever. Further, while patent and copyright protection extends only to certain types of materials or information, trade secret protection extends to a wide range of information. Additionally, trade secrets are not publicly disclosed; with patents, the entire patent file and its contents become public property.

In Texas, trade secret protection is defined by a large body of welldeveloped case …

Should Patent Protection Be Considered For Computer Software-Related Innovations?, Éloïse Gratton

Computer Law Review and Technology Journal

The twentieth century witnessed the development of more significant scientific and technological advances than any other period in history. In today's society computer-related technologies, including software, are at the forefront of change. But at the beginning of the computer age the computer industry overlooked software in favor of more-valuable computer hardware.

The question of software patentability arose during the 1960's and the early 1970's, when the prevailing view of computer suppliers was that software should not be protected by copyright or patent. The industry believed that a system allowing the free exchange and availability of computer programs might stimulate the …

Striking A Balance Between Employer Business Interests And Employee Privacy: Using Respondeat Superior To Justify The Monitoring Of Web-Based, Personal Electronic Mail Accounts Of Employees In The Workplace, Micah Echols

Computer Law Review and Technology Journal

Electronic mail ("e-mail") is a convenient and financially beneficial tool in the workplace. Although businesses that take advantage of e-mail have experienced many benefits, these same businesses also face a number of disadvantages. One such disadvantage is the legal liability that employers may face-under a vicarious liability theory-for the e-mail-related actions of their employees. Due to this exposure, nearly eighty percent of employers have turned to various methods of monitoring their employees, including direct e-mail monitoring. Traditionally, this type of monitoring has been limited to company, proprietary e-mail accounts, in which courts have routinely held that an employee has no …

Gene Patenting: Do The Ends Justify The Means?, Mark A. Chavez

Computer Law Review and Technology Journal

Over the course of the last decade, medical interest and research in the human genome has grown at an exponential rate. As a result, profit-seekers and scientists are turning to patent law to protect their financial and medical interests; recent recipients of patent protection include bacteria, a type of mouse, and even human genes. As these trends in medicine and intellectual property law develop, considerable debates are surging regarding the morality of awarding property rights in biological material, particularly human genes. While both sides of this debate present compelling arguments, if scientists and investors are expected to advance their innovative …
