Qos Issues Of Using Probabilistic Non-Repudiation Protocol In Mobile Ad Hoc Network Environment, Yi-Chi Lin, Jill Slay Dec 2006

Qos Issues Of Using Probabilistic Non-Repudiation Protocol In Mobile Ad Hoc Network Environment, Yi-Chi Lin, Jill Slay

Australian Information Security Management Conference

So as to guarantee the fairness of electronic transactions, users may require a NonRepudiation (NR) service in any type of network. However, most existing NR protocols cannot work properly in a Mobile Ad hoc Network (MANET) due to their characteristics (e.g. limited resources and lack of central authority). The design of the Probabilistic NonRepudiation Protocol (PNRP) is comparatively suitable for the nature of a MANET, but it still poses some QoS issues. This article points out the QoS issues which are caused by using PNRP in a MANET environment. These issues explain the difficult of performing PNRP in such an …

Corruption: The True Cause Of The Resource Curse?, Margie Sharpe Dec 2006

Corruption: The True Cause Of The Resource Curse?, Margie Sharpe

All Theses

The theory of the Resource Curse suggests that countries with high levels of natural resources are actually found to possess lower gross domestic products. The source of this disparity is widely debated; however, this analysis suggests that the underlying force preventing such nations from taking advantage of their natural capital abundance is corruption within their economic and governmental systems. In addition, the resource quality is examined to see that it too affects the ability of a nation to change such assets into a higher overall level of national wealth.

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 …

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 …

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 …

Life Data Analysis Of Repairable Systems: A Case Study On Brigham Young University Media Rooms, Stephen Oluaku Manortey Dec 2006

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 …

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 …

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 …

Synthesis And Optical Properties Of Four Oligothiophene-Ruthenium Complexes And Synthesis Of A Bidentate Ligand For C-F Bond Activation, Joseph S. Bair Dec 2006

Synthesis And Optical Properties Of Four Oligothiophene-Ruthenium Complexes And Synthesis Of A Bidentate Ligand For C-F Bond Activation, Joseph S. Bair

Theses and Dissertations

Photovoltaic cells and fluorescence sensing are two important areas of research in chemistry. The combination of photon-activated electron donors with electron acceptors provides a strong platform for the study of optical devices. A series of four oligothiophene-ruthenium complexes has been synthesized. Variation in oligothiophene length and bipyridine substitution allowed comparison of these variables on electronic properties. The longer oligothiophenes display lower energy absorption and emission compared to the shorter ones. Aromatic conjugation appears more complete with para-, rather than meta-, substitution. Oligothiophenes and Ru(bpy)32+ are highly fluorescent individually, but fluorescence is quenched when connected. Bonds of carbon to fluorine are …
