Efficient Subversion Of Symmetric Encryption With Random Initialization Vector, Joon Sang Baek, Ilsun You Jan 2016

Efficient Subversion Of Symmetric Encryption With Random Initialization Vector, Joon Sang Baek, Ilsun You

Faculty of Engineering and Information Sciences - Papers: Part B

This paper presents an efficient subverted symmetric encryption scheme, which outputs a random initialization vector (IV). Compared with the available scheme of the same kind in the literature, our attack provides a saboteur (big brother) with much faster recovery of a key used in a victim's symmetric encryption scheme. Our result implies that care must be taken when a symmetric encryption scheme with a random IV such as randomized CBC is deployed.


Preliminary Observations Of The Effect Of Plate Roughness And Particle Size On The Determination Of Wall Friction, David B. Hastie, Wendy G. Halford Jan 2016

Preliminary Observations Of The Effect Of Plate Roughness And Particle Size On The Determination Of Wall Friction, David B. Hastie, Wendy G. Halford

Faculty of Engineering and Information Sciences - Papers: Part B

The determination of wall friction angle for bulk materials is vital in applications such as; bin and hopper design, conveyor transfer chutes, rail wagon unloading and any other use where bulk materials flow over a surface. It is generally accepted that the rougher the wall surface, the higher the wall friction angle. This paper will present an investigation of wall samples with various surface finishes using a translational shear tester (based on the design by Jenike). Five aluminium plates; one with a 'smooth' surface and the other four with milled grooves of varying spacing and depth to produce regular 'roughness' …


On The Difficulties Of Quantifying The Segregation Of Fine Powder Blends, David B. Hastie Jan 2016

On The Difficulties Of Quantifying The Segregation Of Fine Powder Blends, David B. Hastie

Faculty of Engineering and Information Sciences - Papers: Part B

This paper reports on the difficulties of finding an accurate and consistent test method for quantifying the segregation of two fine powders. The background is from an industrial project investigating the feasibility of blending pulverised coal and crushed nickel ore in a bulk materials handling application, to ultimately produce nickel. The feasibility of combining the two products early in the process was investigated due to the blend requiring various different handling methods throughout the industrial process, making the constituent products susceptible to segregation. In the experimental investigation, representative samples of each bulk material were used to create a range of …


Estimating The Compression Behaviour Of Metal-Rich Clays Via A Disturbed State Concept (Dsc) Model, Ri-Dong Fan, Martin D. Liu, Yan Jun Du, Suksun Horpibulsuk Jan 2016

Estimating The Compression Behaviour Of Metal-Rich Clays Via A Disturbed State Concept (Dsc) Model, Ri-Dong Fan, Martin D. Liu, Yan Jun Du, Suksun Horpibulsuk

Faculty of Engineering and Information Sciences - Papers: Part B

Many studies have been made on the compression behaviour of clay exposed to metal-rich liquids (metal-rich clay) because metal contamination of clay is found worldwide and increasingly poses as an environmental risk. However, the study on predicting the compression behaviour of contaminated clay with various metal concentrations is very limited. In this paper, a general compression model of the metal-rich clays is proposed based on a general Disturbed State Concept (DSC) compression model. A simplified form of the general model is proposed, and validated based on the compression behaviour of metal-rich clays with various metal concentrations in the pore liquid. …

The Fingerprint Context Aware Partitioning (FCAP) tracking model used received RF signal strength fingerprinting, combined with context aware information about the user's indoor environment. The authors show the use of context aware information in the FCAP model, reduces the effect of wireless …


Concrete-Encased Steel Columns Confined With Large Rupture Strain Frp Composites: Axial Compression Tests, Le Huang, Shi Shun Zhang, Tao Yu, Zhenyu Wang Jan 2016

Concrete-Encased Steel Columns Confined With Large Rupture Strain Frp Composites: Axial Compression Tests, Le Huang, Shi Shun Zhang, Tao Yu, Zhenyu Wang

Faculty of Engineering and Information Sciences - Papers: Part B

Fibre Reinforced (FRP)-confined concrete-encased steel composite columns (FCSCs) are an emerging form of hybrid columns. The idea of a combined use of FRP-confined concrete and an encased steel section not only offers a durable and ductile structural form for new construction, but also can be practiced as an efficient method to retrofit/strengthen deteriorated steel columns. This paper presents a series of axial compression tests on concrete-encased steel columns confined with Large Rupture Strain (LRS) FRP composites, namely, Polyethylene Terephthalate (PET) FRP composites. A total of 12 circular specimans, including 6 FCSCs and 6 FRP-confined concrete circular columns (FCCCs) were tested, …


Certificate-Based Encryption With Keyword Search Enabling Secure Authorization In Electronic Health Record, Clementine Gritti, Willy Susilo, Thomas Plantard Jan 2016

Certificate-Based Encryption With Keyword Search Enabling Secure Authorization In Electronic Health Record, Clementine Gritti, Willy Susilo, Thomas Plantard

Faculty of Engineering and Information Sciences - Papers: Part B

In an e-Health scenario, we study how the practitioners are authorized when they are requesting access to medical documents containing sensitive information. Consider the following scenario. A clinician wants to access and retrieve a patient's Electronic Health Record (EHR), and this means that the clinician must acquire sufficient access right to access this document. As the EHR is within a collection of many other patients, the clinician would need to specify some requirements (such as a keyword) which match the patient's record, as well as having a valid access right. The complication begins when we do not want the server …

As a first step, key by-product streams (such as blast furnace, BOS and sinter dusts) are being evaluated and characterised so that their potential uses in-plant or elsewhere can be assessed/evaluated. These streams contain components including iron and …


Membrane Scaling And Prevention Techniques During Seawater Desalination By Air Gap Membrane Distillation, Hung Duong, Mikel C. Duke, Stephen Gray, Paul Cooper, Long D. Nghiem Jan 2016

Membrane Scaling And Prevention Techniques During Seawater Desalination By Air Gap Membrane Distillation, Hung Duong, Mikel C. Duke, Stephen Gray, Paul Cooper, Long D. Nghiem

Faculty of Engineering and Information Sciences - Papers: Part B

Membrane scaling and mitigation techniques during air gap membrane distillation (AGMD) of seawater were investigated. The results showed a strong influence of AGMD operating temperature on not only the process water flux but also membrane scaling and subsequent cleaning efficiency. Elevating feed/coolant temperature from 35/25 to 60/50 °C increased water flux, but also exacerbated membrane scaling of the AGMD process. Membrane scaling was more severe, and occurred at a lower water recovery (68%) when operating at 60/50 °C compared to 35/25 °C (78%) due to increased concentration polarisation effect. Operating temperature also affected the efficiency of the subsequent membrane cleaning. …


An Analytical Approximation Formula For European Option Pricing Under A New Stochastic Volatility Model With Regime-Switching, Xinjiang He, Song-Ping Zhu Jan 2016

An Analytical Approximation Formula For European Option Pricing Under A New Stochastic Volatility Model With Regime-Switching, Xinjiang He, Song-Ping Zhu

Faculty of Engineering and Information Sciences - Papers: Part B

In this paper, an analytical approximation formula for pricing European options is obtained under a newly proposed hybrid model with the volatility of volatility in the Heston model following a Markov chain, the adoption of which is motivated by the empirical evidence of the existence of regime-switching in real markets. We first derive the coupled PDE (partial differential equation) system that governs the European option price, which is solved with the perturbation method. It should be noted that the newly derived formula is fast and easy to implement with only normal distribution function involved, and numerical experiments confirm that our …

Faculty of Engineering and Information Sciences - Papers: Part B

This study develops a multi-level neuromuscular model consisting of topological pools of spiking motor, sensory and interneurons controlling a bi-muscular model of the human arm. The spiking output of motor neuron pools were used to drive muscle actions and skeletal movement via neuromuscular junctions. Feedback information from muscle spindles were relayed via monosynaptic excitatory and disynaptic inhibitory connections, to simulate spinal afferent pathways. Subject-specific model parameters were identified from human experiments by using inverse dynamics computations and optimization methods. The identified neuromuscular model was used to simulate the biceps stretch reflex and the results were compared to an independent dataset. …

Faculty of Engineering and Information Sciences - Papers: Part B

Hollow bimetallic electrocatalysts have recently stimulated increasing attention due to their accessible interior surface and bimetallic synergetic effect. Herein, for the first time, we successfully anchor a porous AuPt shell on modified silica spheres with the assistance of Pluronic F127. The whole process consists of simple ultrasonic mixing for 30 min at room temperature without any organic solvent. After metal deposition and silica etching, well-defined hollow structures are obtained in high yield. The hollow spheres are further characterized by scanning electron microscopy and transmission electron microscopy. The electrochemical analysis reveals that the as-prepared samples demonstrate superior electrocatalytic activity and durability …

This paper reports on the characterisation of water sprays for the purpose of modelling the effectiveness of such sprays in mitigating the impacts of wildfires on residential buildings. Four types of water spray nozzles were experimentally tested and analysed using a single high-speed camera and image analysis software. The sprays were generated by a misting nozzle, a hollow-cone nozzle, a rotating 'butterfly' sprinkler and a deflector plate sprinkler. Back-illumination was used to produce silhouette images of droplets within each spray. The point spread function half-width of each droplet image was determined, to give an indication of the distance of the …


Investigations Into The Identification And Control Of Outburst In Australian Underground Coal Mines, Dennis J. Black Jan 2016

Investigations Into The Identification And Control Of Outburst In Australian Underground Coal Mines, Dennis J. Black

Faculty of Engineering and Information Sciences - Papers: Part B

Australian coal mines currently use gas content to assess outburst risk. The gas content threshold values for each mine are indirectly determined from measurement of gas volume liberated from 150 g coal samples during Q3 residual gas content testing. It has been more than twenty (20) years since this method, known as DRI900, was presented to the Australian coal industry, and in that time there have been significant changes in mining conditions and the outburst threshold limits used at the benchmark Bulli seam mines.Current coal mining legislation in both Queensland [7] and New South Wales [6] provide little guidance in …

Cfd-Dem Modelling Of Powder Flows And Dust Generation Mechanisms - A Review, Luke Stone, Peter W. Wypych, David B. Hastie, Stefan Zigan

Faculty of Engineering and Information Sciences - Papers: Part B

Dust generation forms a large part of the challenges that bulk materials handling engineers face throughout the life of their career. Dust generation can lead to health problems, explosion risks, material segregation and environment pollution [1-5]. These conditions are typical of run of mine dump hoppers, grain silos, coal train dump stations and alumina storage silos. Computational Fluid Dynamic (CFD) models have been used successfully for predicting fluid flows with a high level of accuracy with the benefit of being less computationally expensive than in the past. Although CFD programs such as ANSYS can be used to successfully model fluids, …


Current Engineering Education And Training Practices On Aboriginal Cultural Heritage, Thomas Goldfinch, Xavier Hollis Jan 2016

Current Engineering Education And Training Practices On Aboriginal Cultural Heritage, Thomas Goldfinch, Xavier Hollis

Faculty of Engineering and Information Sciences - Papers: Part B

CONTEXT Previous research has highlighted the need for engineers to have some background knowledge of Indigenous Australian history, cultures and politics (Goldfinch, Ilango, Roland, and Willis, 2014; Leigh et al., 2015). This is particularly important where project engineers hold responsibility for developing or implementing Aboriginal cultural heritage management plans (Furry, 2015; Hartley, 2015) and compliance with relevant legislation (NSW Government, 2010; 2014). Engineering projects are often enabled, delayed, or significantly altered as a result of how sites and artefacts of significance are managed. At this stage, it is believed that engineers often negotiate these challenges with little to no training …


Interaction Forces In Rc Beams Strengthened With Nsm Frp Round Bars, Shi Shun Zhang, Tao Yu Jan 2016

Interaction Forces In Rc Beams Strengthened With Nsm Frp Round Bars, Shi Shun Zhang, Tao Yu

Faculty of Engineering and Information Sciences - Papers: Part B

The near-surface mounted (NSM) strengthening method has attracted an increasing worldwide attention in the last decade. Although the bond efficiency between FRP and concrete in the NSM method is much improved compared with the externally bonded (EB) FRP strengthening method, debonding failures have also been often observed in reinforced concrete (RC) beams strengthened with NSM FRP bars. In such FRP-strengthened RC beams, debonding may initiate at either of the two ends of the NSM bar (i.e. end debonding), due to the existence of large localized interaction forces between the NSM bar and concrete near the bar ends. This paper presents …


A Bottom-Up Data Collection Methodology For Characterising The Residential Building Stock In Australia, Clayton Mcdowell, Georgios Kokogiannakis, Paul Cooper, Michael P. Tibbs Jan 2016

A Bottom-Up Data Collection Methodology For Characterising The Residential Building Stock In Australia, Clayton Mcdowell, Georgios Kokogiannakis, Paul Cooper, Michael P. Tibbs

Faculty of Engineering and Information Sciences - Papers: Part B

In Australia the majority of the current residential building stock has been constructed with little regard to energy consumption or thermal comfort. With only 1-2 % of Australia's building stock being replaced each year retrofitting solutions are necessary if residential energy consumption is to be reduced. Australia's records of the characteristics of its current building stock are minimal and outdated and thus these need to be renewed to enable the evaluation of retrofit upgrade strategies. Thus this paper presents a methodology and results of a bottom-up data collection tool that captured building and occupant characteristics from 200 elderly low income …

Biofouling Mitigation In Forward Osmosis Using Graphene Oxide Functionalized Thin-Film Composite Membranes, Francois Perreault, Humberto Jaramillo, Ming Xie, Mercy Ude, Long D. Nghiem, Menachem Elimelech

Faculty of Engineering and Information Sciences - Papers: Part B

Forward osmosis (FO) is an emerging membrane process with potential applications in the treatment of highly fouling feedwaters. However, biofouling, the adhesion of microorganisms to the membrane and the subsequent formation of biofilms, remains a major limitation since antifouling membrane modifications offer limited protection against biofouling. In this study, we evaluated the use of graphene oxide (GO) for biofouling mitigation in FO. GO functionalization of thin-film composite membranes (GO-TFC) increased the surface hydrophilicity and imparted antimicrobial activity to the membrane without altering its transport properties. After 1 h of contact time, deposition and viability of Pseudomonas aeruginosa cells on GO-TFC …

Discussion: Assessment Of Smear Parameters For Use In Wick Drain Design, Richard B. Kelly, A Litwinowicz

Faculty of Engineering and Information Sciences - Papers: Part B

As the paper's findings (Kelly, 2014) are premised on 100% degree of consolidation being achieved, which in itself has inherent uncertainties, the consolidation aspect is worthy of closer examination. In this discussion, Consolidation (capital C) refers specifically to primary consolidation being the traditional time-dependent expulsion of water volume under pressure with progress assessed by change in pore pressure. Moreover, the Consolidation phase is most relevant to wick drain effectiveness.

On Minimizing Data Forwarding Schedule In Multi Transmit/Receive Wireless Mesh Networks, He Wang, Kwan-Wu Chin, Sieteng Soh Jan 2016

On Minimizing Data Forwarding Schedule In Multi Transmit/Receive Wireless Mesh Networks, He Wang, Kwan-Wu Chin, Sieteng Soh

Faculty of Engineering and Information Sciences - Papers: Part B

A key problem in wireless mesh networks is forwarding packets to/from one or more gateways with connectivity to the Internet. In this respect, a short link schedule, which determines the transmission time of links, is critical. To date, existing link schedulers do not consider routers that incorporate advances in multiple input multiple output communications, i.e., interference cancellation and spatial multiplexing. In particular, these routers are able to transmit or receive distinct packets on all their links concurrently as well as deliver multiple packets to a neighbor simultaneously. To this end, we consider the problem of deriving a time division multiple …

Faculty of Engineering and Information Sciences - Papers: Part B

This study compares the effectiveness of seven redox-mediating compounds namely, 1-hydrozybenzotriazole (HBT), N-hydroxyphthalimide (HPI), 2,2,6,6-Tetramethyl-1-piperidinyloxy (TEMPO), violuric acid (VA), syringaldehyde (SA), vanillin (VA), and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS), which follow distinct oxidation pathways, for the degradation of trace organic contaminants (TrOCs). These redox-mediators were investigated for improved degradation of four TrOCs showing resistance to degradation by crude laccase from the white-rot fungus Pleurotus ostreatus. ABTS and VA achieved the highest degradation of the phenolic compounds (i.e., oxybenzone and pentachlorophenol), whereas the non-phenolic compounds (i.e., naproxen and atrazine) were best removed using VA or HBT. This implies that the …
