Quantum Beam Science-Applications To Probe Or Influence Matter And Materials, Klaus-Dieter Liss 2017 University of Wollongong

Quantum Beam Science-Applications To Probe Or Influence Matter And Materials, Klaus-Dieter Liss

Faculty of Engineering and Information Sciences - Papers: Part A

The concept of quantum beams unifies a multitude of different kinds of radiation that can be considered as both waves and particles, according to the quantum mechanical model. Examples include light, in the form of X-rays and synchrotron radiation, as well as neutrons, electrons, positrons, muons, protons, ions, and photons. While the past century saw the discovery of these types of radiation and particles along with the investigations of their physical properties and their fundamental interaction with matter, the current century focuses extensively on their applications to characterize and understand materials in their broadest context, under all imaginable conditions. X-rays ...

Rfid Ownership Transfer With Positive Secrecy Capacity Channels, Jorge Munilla Fajardo, Mike Burmester, Alberto Peinado, Guomin Yang, Willy Susilo 2017 Universidad de Malaga

Rfid Ownership Transfer With Positive Secrecy Capacity Channels, Jorge Munilla Fajardo, Mike Burmester, Alberto Peinado, Guomin Yang, Willy Susilo

Faculty of Engineering and Information Sciences - Papers: Part A

RFID ownership transfer protocols (OTPs) transfer tag ownership rights. Recently, there has been considerable interest in such protocols, however, guaranteeing privacy for symmetric-key settings without trusted third parties (TTPs) is a challenge still unresolved. In this paper, we address this issue and show that it can be solved by using channels with positive secrecy capacity. We implement these channels with noisy tags and provide practical values, thus proving that perfect secrecy is theoretically possible. We then define a communication model that captures spatiotemporal events and describe a first example of symmetric-key based OTP that: (i) is formally secure in the ...

Simulation Ballasted Track Behavior: Numerical Treatment And Field Application, Ngoc Trung Ngo, Buddhima Indraratna, Cholachat Rujikiatkamjorn

Faculty of Engineering and Information Sciences - Papers: Part A

The load deformation of ballasted rail tracks subjected to cyclic loading is investigated experimentally using a large-scale track process simulation apparatus and numerically through a combined discrete element-finite-difference approach. Laboratory tests were performed to examine the deformation and degradation of ballast subjected to cyclic loading at 15 Hz and a lateral confinement of 10 kPa 10 kPa. The laboratory results reveal that ballast undergoes significant deformation during the initial load cycles, followed by gradually increasing deformation attaining a steady value toward the end of testing. A numerical model based on a combined discrete element method (DEM) and finite-difference method (FDM ...


A Framework To Assess Newmark-Type Simplified Methods For Evaluation Of Earthquake-Induced Deformation Of Embankments, Mojtaba E. Kan, Hossein Taiebat, Mahdi Taiebat 2017 University of Wollongong

A Framework To Assess Newmark-Type Simplified Methods For Evaluation Of Earthquake-Induced Deformation Of Embankments, Mojtaba E. Kan, Hossein Taiebat, Mahdi Taiebat

Faculty of Engineering and Information Sciences - Papers: Part A

The simplified procedures for evaluation of the earthquake induced displacement in earth and rockfill dams are widely used in practice. These methods are simple, inexpensive, and substantially less time consuming as compared to the complicated stress-deformation approaches. They are especially recommended to be used as a screening tool, to identify embankments with marginal factor of safety, assuming that these methods always give conservative estimates of settlements. However recent studies show that application of these methods may not be conservative in some cases, especially when the tuning ratio of a dam is within a certain range. In this paper the fundamental ...


Osmotic Versus Conventional Membrane Bioreactors Integrated With Reverse Osmosis For Water Reuse: Biological Stability, Membrane Fouling, And Contaminant Removal, Wenhai Luo, Hop Phan, Ming Xie, Faisal I. Hai, William E. Price, Menachem Elimelech, Long D. Nghiem 2017 University of Wollongong

Osmotic Versus Conventional Membrane Bioreactors Integrated With Reverse Osmosis For Water Reuse: Biological Stability, Membrane Fouling, And Contaminant Removal, Wenhai Luo, Hop Phan, Ming Xie, Faisal I. Hai, William E. Price, Menachem Elimelech, Long D. Nghiem

Faculty of Engineering and Information Sciences - Papers: Part A

This study systematically compares the performance of osmotic membrane bioreactor - reverse osmosis (OMBR-RO) and conventional membrane bioreactor - reverse osmosis (MBR-RO) for advanced wastewater treatment and water reuse. Both systems achieved effective removal of bulk organic matter and nutrients, and almost complete removal of all 31 trace organic contaminants investigated. They both could produce high quality water suitable for recycling applications. During OMBR-RO operation, salinity build-up in the bioreactor reduced the water flux and negatively impacted the system biological treatment by altering biomass characteristics and microbial community structure. In addition, the elevated salinity also increased soluble microbial products and extracellular polymeric ...

Stir Casting Process For Manufacture Of Al-Sic Composites, Shahin Soltani, R Azari Khosroshahi, R Taherzadeh Mousavian, Zhengyi Jiang, Alireza Fadavi Boostani, D Brabazon

Faculty of Engineering and Information Sciences - Papers: Part A

Stir casting is an economical process for the fabrication of aluminum matrix composites. There are many parameters in this process, which affect the final microstructure and mechanical properties of the composites. In this study, micron-sized SiC particles were used as reinforcement to fabricate Al-3 wt% SiC composites at two casting temperatures (680 and 850 °C) and stirring periods (2 and 6 min). Factors of reaction at matrix/ceramic interface, porosity, ceramic incorporation, and agglomeration of the particles were evaluated by scanning electron microscope (SEM) and high-resolution transition electron microscope (HRTEM) studies. From microstructural characterizations, it is concluded that the shorter ...

The Once-Once Principle (OOP) suggests that citizens and businesses should have the right to supply information only once to a public administration. It would then be the responsibility of public administration offices to take all necessary actions in order to internally share this data by respecting the relevant data protection rules. The overall aim is to reduce administrative burden. The implementation of the OOP is high on the political agenda of many countries including the Member States of the European Union. The aim of this panel is to enable an open discussion between the panelists and the audience in order ...


An Experimental Study Of Axial Load Transfer Mechanisms Of Cable Bolts Using Axially Split Embedment Apparatus, Ali Mirza, Naj Aziz 2017 University of Wollongong

An Experimental Study Of Axial Load Transfer Mechanisms Of Cable Bolts Using Axially Split Embedment Apparatus, Ali Mirza, Naj Aziz

Faculty of Engineering and Information Sciences - Papers: Part B

The load transfer mechanisms of cable bolts differ from those for normal rebar bolts. The cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. Tendon bolts (rebar and cable) are normally evaluated for their strength and load transfer properties. The tendon strength can be evaluated by the tensile failure tests, while the load transfer strength is evaluated by the pull and shear strength tests. Short Encapsulation Pull Testing (SEPT) is normally used to study the load transfer capacities of tendons, and it can ...


Equivalence And Stable Isomorphism Of Groupoids, And Diagonal-Preserving Stable Isomorphisms Of Graph C* -Algebras And Leavitt Path Algebras, Toke Meier Carlsen, Efren Ruiz, Aidan Sims 2017 University of the Faroe Islands

Equivalence And Stable Isomorphism Of Groupoids, And Diagonal-Preserving Stable Isomorphisms Of Graph C* -Algebras And Leavitt Path Algebras, Toke Meier Carlsen, Efren Ruiz, Aidan Sims

Faculty of Engineering and Information Sciences - Papers: Part B

We prove that ample groupoids with sigma-compact unit spaces are equivalent if and only if they are stably isomorphic in an appropriate sense, and relate this to Matui's notion of Kakutani equivalence. We use this result to show that diagonal-preserving stable isomorphisms of graph C*-algebras or Leavitt path algebras give rise to isomorphisms of the groupoids of the associated stabilised graphs. We deduce that the Leavitt path algebras LZ(E_2) and LZ(E2-) are not stably *-isomorphic.

Action Learning In Undergraduate Engineering Thesis Supervision, Brad Stappenbelt

Faculty of Engineering and Information Sciences - Papers: Part B

In the present action learning implementation, twelve action learning sets were conducted over eight years. The action learning sets consisted of students involved in undergraduate engineering research thesis work. The concurrent study accompanying this initiative investigated the influence of the action learning environment on student approaches to learning and any accompanying academic, learning and personal benefits realised. The influence of preferred learning styles on set function and student adoption of the action learning process were also examined. The action learning environment implemented had a measurable significant positive effect on student academic performance, their ability to cope with the stresses associated ...


The Impact Of The Mode Of Survey Administration On Estimates Of Daily Smoking For Mobile Phone Only Users, Joseph Hanna, Damien V. Cordery, David G. Steel, Walter R. Davis, Timothy Harrold 2017 New South Wales Health

The Impact Of The Mode Of Survey Administration On Estimates Of Daily Smoking For Mobile Phone Only Users, Joseph Hanna, Damien V. Cordery, David G. Steel, Walter R. Davis, Timothy Harrold

Faculty of Engineering and Information Sciences - Papers: Part B

Background: Over the past decade, there have been substantial changes in landline and mobile phone ownership, with a substantial increase in the proportion of mobile-only households. Estimates of daily smoking rates for the mobile phone only (MPO) population have been found to be substantially higher than the rest of the population and telephone surveys that use a dual sampling frame (landline and mobile phones) are now considered best practice. Smoking is seen as an undesirable behaviour; measuring such behaviours using an interviewer may lead to lower estimates when using telephone based surveys compared to self-administered approaches. This study aims to ...


Trucks Are Destroying Our Roads And Not Picking Up The Repair Cost, Philip G. Laird 2017 University of Wollongong

Trucks Are Destroying Our Roads And Not Picking Up The Repair Cost, Philip G. Laird

Faculty of Engineering and Information Sciences - Papers: Part B

It's high time Australia changed its current road user charges for trucks. The shortfall between the charges for heavy vehicles and the money spent on things like road system maintenance, construction costs, road crashes involving heavy trucks, emissions, pollution and urban road congestion amounts to a taxpayer subsidy for the industry of at least A$3 billion per annum. The current charges, like those of cars, rely only on annual registration fees and fuel taxation. Instead Australia should be following the lead of New Zealand, Switzerland and some other European countries and introducing a charge system based on mass ...


The Geometric Triharmonic Heat Flow Of Immersed Surfaces Near Spheres, James A. McCoy, Scott Parkins, Glen Wheeler 2017 University of Wollongong

The Geometric Triharmonic Heat Flow Of Immersed Surfaces Near Spheres, James A. Mccoy, Scott Parkins, Glen Wheeler

Faculty of Engineering and Information Sciences - Papers: Part B

We consider closed immersed surfaces in R^3 evolving by the geometric triharmonic heat flow. Using local energy estimates, we prove interior estimates and a positive absolute lower bound on the lifespan of solutions depending solely on the local concentration of curvature of the initial immersion in L^2. We further use an {\epsilon}-regularity type result to prove a gap lemma for stationary solutions. Using a monotonicity argument, we then prove that a blowup of the flow approaching a singular time is asymptotic to a non-umbilic embedded stationary surface. This allows us to conclude that any solution with initial ...


Privacy-Preserving Mutual Authentication In Rfid With Designated Readers, Fuchun Guo, Yi Mu, Willy Susilo, Vijay Varadharajan 2017 University of Wollongong

Privacy-Preserving Mutual Authentication In Rfid With Designated Readers, Fuchun Guo, Yi Mu, Willy Susilo, Vijay Varadharajan

Faculty of Engineering and Information Sciences - Papers: Part B

We study privacy-preserving mutual authentication in radio-frequency identification systems with designated readers (PP-MADR in short). In PP-MADR, each tag has its designated-reader group instead of all readers, and only tags and their designated readers can authenticate each other. Other readers and adversaries cannot trace tags or know their designated readers. The most challenging task of constructing such a PP-MADR protocol is the verification of reader designation without compromising tag privacy. We found that traditional solutions are impractical due to linear storage growth on tags, linear computation growth on tags, or requiring new key generations for designated readers. In this paper ...

Mergeable And Revocable Identity-Based Encryption, Shengmin Xu, Guomin Yang, Yi Mu, Willy Susilo 2017 University of Wollongong

Mergeable And Revocable Identity-Based Encryption, Shengmin Xu, Guomin Yang, Yi Mu, Willy Susilo

Faculty of Engineering and Information Sciences - Papers: Part B

Identity-based encryption (IBE) has been extensively studied and widely used in various applications since Boneh and Franklin proposed the first practical scheme based on pairing. In that seminal work, it has also been pointed out that providing an efficient revocation mechanism for IBE is essential. Hence, revocable identity-based encryption (RIBE) has been proposed in the literature to offer an efficient revocation mechanism. In contrast to revocation, another issue that will also occur in practice is to combine two or multiple IBE systems into one system, e.g., due to the merge of the departments or companies. However, this issue has ...
