The Effects Of Viscoelastic Behavior On The Operation Of A Delayed Resonator Vibration Absorber, John Cowans Dec 2006

The Effects Of Viscoelastic Behavior On The Operation Of A Delayed Resonator Vibration Absorber, John Cowans

All Theses

Delayed resonators have proven to be effective vibration absorbers (VAs) for tracking and canceling the effects of harmonic excitations on a structure. The Delayed Resonator (DR) is selfcontained, as no information from outside of its substructure is required for proper operation. It adjusts for variations in frequency using time-delay and gain as control parameters.
This thesis examines the relationship between viscoelastic (VE) loss mechanisms in systems with DR and the choice of modeling method used to calculate control parameters and determine system stability. It is hypothesized that a VE loss mechanism approximated by a single viscous dashpot may lead to …

Internal Combustion Engine Cooling Strategies: Theory And Test, John Chastain Dec 2006

Internal Combustion Engine Cooling Strategies: Theory And Test, John Chastain

All Theses

Advanced internal combustion engine thermal management systems can enhance overall engine performance through the use of computer controlled cooling system actuators. Existing ground vehicle cooling systems generally have performance limitations due to the fixed behavior of the wax-based thermostat valve and crankshaft dependent operation of the coolant pump and radiator fan. Upgrading the traditional thermostat valve, water pump, and radiator fan with actuators permit real time computer control for improved temperature tracking and reduced power consumption. In this paper, the benefits associated with advanced automotive cooling systems are experimentally investigated. A 4.6L engine with a real-time data acquisition and control …

Uncontrollable Privacy - The Right That Every Attacker Desires, Giannakis Antoniou, Stefanos Gritzalis Dec 2006

Uncontrollable Privacy - The Right That Every Attacker Desires, Giannakis Antoniou, Stefanos Gritzalis

Australian Information Security Management Conference

The request of the Internet users enjoying privacy during their e-activities enforces the Internet society to develop techniques which offer privacy to the Internet users, known as Privacy Enhancing Technologies (PETs). Among the Internet users, there are attackers who desire more than anything else to enjoy privacy during their malicious actions, and a PET is what they were looking for. Thus, although a PET should offer privacy to the internet users, proper techniques should also be employed in order to help the victims during the investigation procedure and unveil the identification of the attackers. The paper summarizes the current design …

Network Forensics And Privacy Enhancing Technologies “Living” Together In Harmony, Giannakis Antoniou, Stefanos Gritzalis Dec 2006

Network Forensics And Privacy Enhancing Technologies “Living” Together In Harmony, Giannakis Antoniou, Stefanos Gritzalis

Australian Information Security Management Conference

Privacy Enhancing Technology (PET) is the technology responsible to hide the identification of Internet users, whereas network forensics is a technology responsible to reveal the identification of Internet users who perform illegal actions through the Internet. The paper identifies the collision of these opposite-goal technologies and describes what happens in case they come across. Can a Network Forensics protocol discover the identification of an Internet user who is trying to be anonymous behind a PET? The paper also proposes a way to bridge and eliminate the gap between these two technologies.

Making Research Real: Is Action Research A Suitable Methodology For Medical Information Security Investigations?, Patricia A. Williams Dec 2006

Making Research Real: Is Action Research A Suitable Methodology For Medical Information Security Investigations?, Patricia A. Williams

Australian Information Security Management Conference

In the medical field, information security is an important yet vastly underrated issue. Research into the protection of sensitive medical data is often technically focused and does not address information systems and behavioural aspects integral to effective information security implementation. Current information security policy and guidelines are strategically oriented which, whilst relevant to large organisations, are less supportive to smaller enterprises such as primary care practices. Further, the conservative nature of the medical profession has been shown to hinder investigation into information technology use and management, making effective improvement based on research problematical. It is an environment which relies greatly …

The Derivation Of A Conceptual Model For It Security Outsourcing, W D. Wilde, M J. Warren, W Hutchinson Dec 2006

The Derivation Of A Conceptual Model For It Security Outsourcing, W D. Wilde, M J. Warren, W Hutchinson

Australian Information Security Management Conference

IT security outsourcing is the establishment of a contractual relationship between an organization with an outside vendor which assumes responsibility for the organisation’s security functions. Outsourcing in IS has had a variable history of success and the complexity of the decision making process leads to a substantial degree of uncertainty. This is especially so in the realm of IS security since the protection of both hardware and software systems is placed in the hands of an external provider. This paper is a fuller and more comprehensive paper of a previous paper outlining the effectiveness of the decision making process by …

Life Data Analysis Of Repairable Systems: A Case Study On Brigham Young University Media Rooms, Stephen Oluaku Manortey

Theses and Dissertations

It is an undisputable fact that most systems, upon consistence usage are bound to fail in the performance of their intended functions at a point in time. When this occurs, various strategies are set in place to restore them back to a satisfactory performance. This may include replacing the failed component with a new one, swapping parts, resetting adjustable parts to mention but a few. Any such system is referred to as a repairable system. There is the need to study these systems and use statistical models to predict their failing time and be able to set modalities in place …

Eliminating Listeria Monocytogenes In Packed Ready-To-Eat Poultry Products By Combining In-Package Pasteurization With Nisin And/Or Lysozyme, Sunil Mangalassary

All Dissertations

Listeria monocytogenes is a significant food-borne pathogen particularly associated with ready-to-eat (RTE) meat and poultry products which can grow and multiply at refrigeration temperatures. In-package pasteurization is an effective post-lethality intervention to reduce microbial contamination of RTE meat products. Enhancing the efficiency of in-package pasteurization is vital in reducing the L. monocytogenes population as well as in preserving the quality of the meat product. The first section of the dissertation research evaluated the effect of product thickness on the surface heating rate and final surface temperature during in-package pasteurization of vacuum-packaged bologna. Three thicknesses (4, 12, and 20 mm), corresponding …

Path Integral Formulation Of Langeinv Dynamics With Applications To Rare-Event Systems, Bradley Dickson Dec 2006

Path Integral Formulation Of Langeinv Dynamics With Applications To Rare-Event Systems, Bradley Dickson

All Dissertations

In the last decade great efforts have been made to efficiently study the behaviors of rare-event systems. The methods and theories developed in pursuit of this goal are far from unified and are instead applied on a case-by-case basis where one makes a best educated guess as to which approach may afford the greatest chance of studying the rare-event system in question. The work contained here is directed at further development of one of these sets of methods and theories. Specifically, a new theory of dynamics in the Langevin path space is developed with emphasis on generating and sampling Langevin …

Identification Of The Rassf3 Gene As A Potential Tumor Suppressor Responsible For The Resistance To Mammary Tumor Development In Mmtv/Neu Transgenic Mice, Isabelle Jacquemart

All Dissertations

The MMTV/neu transgenic mouse line is a well-documented animal model for studying HER2/neu-related breast cancer. It has been reported that a small percentage, approximately 20%, of the virgin female MMTV/neu mice seems resistant to the development of mammary gland adenoma, despite the overexpression of the neu oncogene.
To identify the factors that are responsible for the tumor resistance in these MMTV/neu female transgenic mice, comparative genetic profiling was used to screen the alterations in gene expression in the mammary gland. A novel gene named the RAS Association domain (RalGDS/AF-6) Family 3 (Rassf3), which belongs to a family of RAS effectors …

Suboptimal Feedback Control Design Of Constrained Parabolic Systems In Uncertainty Conditions, Boris S. Mordukhovich Dec 2006

Suboptimal Feedback Control Design Of Constrained Parabolic Systems In Uncertainty Conditions, Boris S. Mordukhovich

Mathematics Research Reports

The paper concerns minimax control problems forlinear multidimensional parabolic systems with distributed uncertain perturbations and control functions acting in the Dirichlet boundary conditions. The underlying parabolic control system is functioning under hard/pointwise constraints on control and state variables. The main goal is to design a feedback control regulator that ensures the required state performance and robust stability under any feasible perturbations and minimize an energy-type functional under the worst perturbations from the given area. We develop an efficient approach to the minimax control design of constrained parabolic systems that is based on certain characteristic features of the parabolic dynamics including …
