Topics In Chaotic Secure Communication, Andrew Thomas Parker

Doctoral Dissertations

Results in nonlinear dynamics and chaos during this decade have been applied to problems in secure communications with limited success. Most of these applications have been based on the chaotic synchronization property discovered by Pecora and Carroll in 1989 [37]. Short [44, 45, 48] demonstrated the effectiveness of nonlinear dynamic (NLD) forecasting methods in breaking this class of communication schemes. In response, investigators have proposed enhancements to the basic synchronization technique in an attempt to improve the security properties. In this work two of these newer communication systems will be analyzed using NLD forecasting and other techniques to determine the …

New Methods For Modeling Accelerated Life Test Data, Michelle Hopkins Capozzoli

Doctoral Dissertations

An accelerated life test (ALT) is often used to obtain timely information for highly reliable items. The increased use of ALTs has resulted in nontraditional reliability data which can not be analyzed with standard statistical methodologies. I propose new methods for analyzing ALT data for studies with (1) two independent populations, (2) paired samples and (3) limited failure populations (LFP). Here, the Weibull distribution, which can accommodate a variety of failure rates, is assumed for the models I develop. For case (1), a parametric hypothesis test, a Bayesian analysis and a test using partial likelihood are proposed and discussed. For …

Hardware-Software Codesign In A High-Level Synthesis Environment, Tamas L. Visegrady

Doctoral Dissertations

Interfacing hardware-oriented high-level synthesis to software development is a computationally hard problem for which no general solution exists. Under special conditions, the hardware-software codesign (system-level synthesis) problem may be analyzed with traditional tools and efficient heuristics. This dissertation introduces a new alternative to the currently used heuristic methods. The new approach combines the results of top-down hardware development with existing basic hardware units (bottom-up libraries) and compiler generation tools. The optimization goal is to maximize operating frequency or minimize cost with reasonable tradeoffs in other properties.

The dissertation research provides a unified approach to hardware-software codesign. The improvements over previously …

A Constraint-Based Framework For Configuration, Daniel Sabin

Doctoral Dissertations

The research presented here aims at providing a comprehensive framework for solving configuration problems, based on the Constraint Satisfaction paradigm. This thesis is addressing the two main issues raised by a configuration task: modeling the problem and solving it efficiently. Our approach subsumes previous approaches, incorporating both Simplification and further extension, offering increased representational power and efficiency.

Modeling. We advance the idea of local, context independent models for the types of objects in the application domain, and show how the model of an artifact can be built as a composition of local models of the constituent parts. Our modeling technique …

The Mut-2 Mutator Of Caenorhabditis Elegans, Kathrine Queta Flint Boese

Doctoral Dissertations

The mut-2 mutator plays multiple regulatory roles in the germ line of C. elegans. In addition to regulating germ line transposition of at least four distinct transposon families (Tc1, Tc3, Tc4 and Tc5) mut-2 is implicated in chromosome segregation. Animals that harbor the mut-2 mutator produce broods with a higher incidence of males phenotype (Him) as a result of an increase in X chromosome non-disjunction during meiosis.

Using the Him phenotype conferred by mut-2(r459), I mapped the gene to the dpy-14 sem-4 interval on LGI. However, efforts to identify a molecular clone of the gene were hampered because the available …

The Development Of Rna Probe And Rt-Pcr Assays For The Detection Of Enteroviruses In Sludge, Amy Elisabeth Moore

Doctoral Dissertations

Many wastewater treatment plants generate more sludge than can be disposed of by conventional means. The United States Environmental Protection Agency (USEPA) has encouraged communities to dispose of sludge by land application. Sludge may contain enteric viruses that are known to survive for long periods of time in sludge-amended soil and can travel great distances, potentially contaminating surface and ground water.

Standard cell culture methods for the detection of enteric viruses are costly and results are not obtained for 30 or more days. The development of methods that provide results more quickly and with lower cost are needed.

The Dynamics Of Rotor With Rubbing, Jerzy T. Sawicki, Joe Padovan, Rabih Al-Khatib

Mechanical Engineering Faculty Publications

This paper presents the description of some phenomena associated with dynamic behavior of rotors interacting with stationary components. Numerical simulations show rotor vibration spectrum rich in subharmonic, quasi-periodic, and chaotic vibrations. The nonlinear calculation techniques are applied to demonstrate the changes of the vibration patterns for different operating conditions. Some conclusions are discussed with regard to unique characteristics of rub-induced rotor response, initial conditions, as well as appropriate ranges of system parameters. Of special interest are the changes in the apparent nonlinearity of the system dynamics as rubs are induced at different rotor speeds. In particular, starting with 2nd order …

Borderland "Day Tourists" From The East: Trieste's Transitory Shopping Fair, Julian V. Minghi

Visions in Leisure and Business

Flows of people across international boundaries to shop have long been a common phenomenon. The end of the Cold War removed barriers to such flows from Eastern to Western Europe and gave rise to a distinctive strain of borderland shopper-officially a "day tourist" from Central Europe, but in reality a professional shopper working as an essential part of an international retail distribution system linking supply from the West to consumption in the East. The case of Trieste (Italy) is examined. The city's borderland shoppers became important during the late 1980s and activity peaked in 1993-5 as bus loads of Central …

Segmentation As A Method For Improving Model Generated Estimates Of Recreational Boating Use, Tsung-Chiung Wu, Edward M. Mahoney, Daniel J. Stynes

Visions in Leisure and Business

The primary purpose of this study is to develop a system of models based on boat storage segments that can generate different estimates of boating use for regions and counties. It is based on the premise that models. that incorporate market segmentation are more efficient and generate more accurate estimates of recreational use when a market is comprised of identifiable market segments. The results show that incorporating storage segments as part of the system of models improves estimates of both the amount and spatial distribution of boating use. The boating use estimates generated by the system of models captures the …

Service-Learning And School Curriculum, Amy Yip Ah-May

Special Topics, General

Service-Learning extends the learning process from the classroom to the community, which becomes a supplementary resource to facilitate teaching and learning. This paper uses fragments of reflections to illustrate how Service-Learning course participants learn through the community-service projects and how they feel about their experiences as project leaders. The literature used provides a rich source of data about the meaning of Service-Learning and empirical evidences of the educational effects of learning through serving others. This paper argues that the Hong Kong school curriculum is examination driven and focused on the academic. There is a neglect in the social, moral and …

The Use Of Service Learning To Promote Understanding Of Gang-Related Issues Faced By Adolescents, Patrice Paul, Kathy Sexton-Radek, Janina Adickas, Bridget Fousek

School K-12

Service learning provides an opportunity for college students to experience classroom curriculum in a real-life setting. In addition, service learning provides the community with services otherwise not available. Such a program has been designed to assist with reduction of violence in the schools while simultaneously allowing college students to experience, hands-on, the people and issues they are studying. In this program, students in an adolescent development course were trained in a six-week group intervention aimed at building skills for positive communication, resolving differences, and preventing violence. A specific protocol involving skill-building exercises, role-plays, discussion. and at-home assignments was followed. Specific …

Analysis Of A Lithium/Thionyl Chloride Battery Under Moderate-Rate Discharge, Mukul Jain, Ganesan Nagasubramanian, Rudolph G. Jungst, John W. Weidner

Faculty Publications

A one-dimensional mathematical model of a spirally wound lithium/thionyl chloride primary battery is developed and used for parameter estimation and design studies. The model formulation is based on the fundamental conservation laws using porous electrode theory and concentrated solution theory. The model is used to estimate the transference number, the diffusion coefficient, and the kinetic parameters for the reactions at the anode and the cathode as a function of temperature. These parameters are obtained by fitting the simulated capacity and average cell voltage to experimental data over a wide range of temperatures (–55 to 49°C) and discharge loads (10-250 ). …

Determination Of The Lithium Ion Diffusion Coefficient In Graphite, Ping Yu, Branko N. Popov, James A. Ritter, Ralph E. White

Faculty Publications

A complex impedance model for spherical particles was used to determine the lithium ion diffusion coefficient in graphite as a function of the state of charge (SOC) and temperature. The values obtained range from of 1.12 × 10^–10 to 6.51 × 10^–11 cm²/s at 25°C for 0 and 30% SOC, respectively, and for 0% SOC, the value at 55°C was 1.35 × 10^–10 cm²/s. The conventional potentiostatic intermittent titration technique (PITT) and Warburg impedance approaches were also evaluated, and the advantages and disadvantages of these techniques were exposed

A Study Of Certain Fourth Order Linear Differential Equations, Bachyen Dao

Theses (Pre-2016)

The main goal is to study the pair of fourth order linear differential equations. (E) y"" - P(x)y = ° and (E+) y"" + P(x)y = ° Where P = P (x) is a positive, continuous function defined on [0, (0). These two equations have always been studied separately. The fact that either all the solutions of (E+) are oscillatory or all are non-oscillatory, while (E) always has a non-oscillatory solution, provides a demonstration of the apparent independence of the two equations in terms of oscillation. However, contrary to this evidence, it is shown that there is a relationship between …

A Compensated Acoustic Actuator For Systems With Strong Dynamic Pressure Coupling, Charles Birdsong, Clark J. Radcliffe

Mechanical Engineering

This study improves the performance of a previously developed acoustic actuator in the presence of an acoustic duct system with strong pressure coupling. The speaker dynamics and the acoustic duct dynamics are first modeled separately. The two systems are then coupled, and the resulting system is modeled. A velocity sensor is developed and used in feedback compensation. The resulting speaker system has minimal magnitude and phase variation over a 20–200 Hz bandwidth. These conclusions are verified through experimental results.
