Response Of Static And Cyclic Laterally Loaded Rigid Piles In Sand, Hongyu Qin, Wei Dong Guo Jan 2016

Response Of Static And Cyclic Laterally Loaded Rigid Piles In Sand, Hongyu Qin, Wei Dong Guo

Faculty of Engineering and Information Sciences - Papers: Part A

An experimental investigation was made into response of piles in sand subjected to lateral cyclic loading. Seven instrumented model piles were tested individually. Five tests were conducted under typical magnitude, and number of cycle loading, and two were under static loading. The results were used to deduce modulus of subgrade reaction k and the profile of limiting lateral resistance force per unit length (LFP, pu profile) in light of closed-form solutions. The study demonstrates a large impact of lateral (cyclic) load level than on the number of cycles, a 1.5-2.8 times increase in the modulus k, and a 10% reduction …

Analysis Of The Magnetic Torque On A Tilted Permanent Magnet For Drug Delivery In Capsule Robots, Fredy Munoz, Gursel Alici, Hao Zhou, Weihua Li, Metin Sitti Jan 2016

Analysis Of The Magnetic Torque On A Tilted Permanent Magnet For Drug Delivery In Capsule Robots, Fredy Munoz, Gursel Alici, Hao Zhou, Weihua Li, Metin Sitti

Faculty of Engineering and Information Sciences - Papers: Part A

In this paper, we present the analysis of the torque transmitted to a tilted permanent magnet that is to be embedded in a capsule robot to achieve targeted drug delivery. This analysis is carried out by using an analytical model and experimental results for a small cubic permanent magnet that is driven by an external magnetic system made of an array of arc-shaped permanent magnets (ASMs). Our experimental results, which are in agreement with the analytical results, show that the cubic permanent magnet can safely be actuated for inclinations lower than 75° without having to make positional adjustments in the …

Asl-Incorporated Pharmacokinetic Modelling Of Pet Data With Reduced Acquisition Time: Application To Amyloid Imaging, Catherine L. Scott, Jieqing Jiao, Andrew Melbourne, Jonathan M. Schott, Brian F. Hutton, Sebastien Ourselin

Faculty of Engineering and Information Sciences - Papers: Part A

Pharmacokinetic analysis of Positron Emission Tomography (PET) data typically requires at least one hour of image acquisition, which poses a great disadvantage in clinical practice. In this work, we propose a novel approach for pharmacokinetic modelling with significantly reduced PET acquisition time, by incorporating the blood flow information from simultaneously acquired arterial spin labelling (ASL) magnetic resonance imaging (MRI). A relationship is established between blood flow, measured by ASL, and the transfer rate constant from plasma to tissue of the PET tracer, leading to modified PET kinetic models with ASL-derived flow information. Evaluation on clinical amyloid imaging data from an …

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 …

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 …

The Effect Of Binary And Ternary Mineral Combinations On The Reactivity Of A Coke Analogue, Raymond Longbottom, Brian J. Monaghan, Guangqing Zhang, Azrin A. Chowdhury, Merrick R. Mahoney, Kim Hockings, Mark H. Reid

Faculty of Engineering and Information Sciences - Papers: Part B

The effect of the mineral matter on the reactivity of a coke analogue was examined through the addition of binary and ternary combinations of magnetite (Fe3O4), troilite (FeS) and quartz (SiO2). The use of coke at a laboratory scale has issues arising from it heterogeneity and complex nature. The coke analogue was developed to help alleviate these issues, being a laboratory tool that has a simplified carbon structure and in which the mineral content, particle size and distribution is largely controlled. The reactivity of the coke analogue with CO2 was measured using a TGA system at 1100°C under conditions similar …

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 Jan 2016

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 Jan 2016

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.

Impacts Of Redox-Mediator Type On Trace Organic Contaminants Degradation By Laccase: Degradation Efficiency, Laccase Stability And Effluent Toxicity, Bradley Ashe, Luong Nguyen, Faisal I. Hai, Duu-Jong Lee, Jason P. Van De Merwe, Frederic Leusch, William E. Price, Long D. Nghiem

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 …

Stress-State Monitoring Of Coal Pillars During Room And Pillar Extraction, Petr Waclawik, Jiri Ptacek, Petr Konicek, Radovan Kukutsch, Jan Nemcik Jan 2016

Stress-State Monitoring Of Coal Pillars During Room And Pillar Extraction, Petr Waclawik, Jiri Ptacek, Petr Konicek, Radovan Kukutsch, Jan Nemcik

Faculty of Engineering and Information Sciences - Papers: Part B

Current mining activities of the OKD mines are primarily focused on coal seams within the Karvina Formation in the Karvina sub-basin. A considerable amount of coal reserves are situated in protection pillars that lie under built-up areas. The longwall mining method is not applicable in these areas because significant deformation of the surface is not permitted. For this reason OKD is considering using alternative methods of mining to minimise subsidence. The room and pillar method has been trialed with specific coal pillars in order to minimise strata convergence. The method was implemented in the shaft protective pillar at the CSM …

Trace Formulas For A Class Of Non-Fredholm Operators: A Review, Alan L. Carey, Fritz Gesztesy, Harald Grosse, Galina Levitina, Denis Potapov, F Sukochev, Dima Zanin

Faculty of Engineering and Information Sciences - Papers: Part B

Take a one-parameter family of self-adjoint Fredholm operators {A(t)}t∈R on a Hilbert space H, joining endpoints A±. There is a long history of work on the question of whether the spectral flow along this path is given by the index of the operator DA=(d/dt)+A acting in L2(R;H), where A denotes the multiplication operator (Af)(t)=A(t)f(t) for f∈dom(A). Most results are about the case where the operators A(⋅) have compact resolvent. In this article, we review what is known when these operators have some essential spectrum and describe some new results.

Combining Coagulation/Miex With Biological Activated Carbon Treatment To Control Organic Fouling In The Microfiltration Of Secondary Effluent, Biplob Kumar Pramanik, Linhua Fan, Linhua Fan Jan 2016

Combining Coagulation/Miex With Biological Activated Carbon Treatment To Control Organic Fouling In The Microfiltration Of Secondary Effluent, Biplob Kumar Pramanik, Linhua Fan, Linhua Fan

Faculty of Engineering and Information Sciences - Papers: Part B

Coagulation, magnetic ion exchange resin (MIEX) and biological activated carbon (BAC) were examined at lab scale as standalone, and sequential pre-treatments for controlling the organic fouling of a microfiltration membrane by biologically treated secondary effluent (BTSE) using a multi-cycle approach. MIEX gave slightly greater enhancement in flux than coagulation due to greater removal of high molecular weight (MW) humic substances, although it was unable to remove high MW biopolymers. BAC treatment was considerably more effective for improving the flux than coagulation or MIEX. This was due to the biodegradation of biopolymers and/or their adsorption by the biofilm, and adsorption of …

Analysis Of Variability Of Tropical Pacific Sea Surface Temperatures, Georgina Davies, Noel A. Cressie Jan 2016

Analysis Of Variability Of Tropical Pacific Sea Surface Temperatures, Georgina Davies, Noel A. Cressie

Faculty of Engineering and Information Sciences - Papers: Part B

Sea surface temperature (SST) in the Pacific Ocean is a key component of many global climate models and the El Niño-Southern Oscillation (ENSO) phenomenon. We shall analyse SST for the period November 1981-December 2014. To study the temporal variability of the ENSO phenomenon, we have selected a subregion of the tropical Pacific Ocean, namely the Niño 3.4 region, as it is thought to be the area where SST anomalies indicate most clearly ENSO's influence on the global atmosphere. SST anomalies, obtained by subtracting the appropriate monthly averages from the data, are the focus of the majority of previous analyses of …

Hybrid Double-Skin Tubular Columns With A Large Rupture Strain Frp Outer Tube: Stub Column Tests, Tao Yu, Shi Shun Zhang, Le Huang, Chun Wa Chan

Faculty of Engineering and Information Sciences - Papers: Part B

Hybrid fiber-reinforced polymer (FRP)-concrete-steel double-skin tubular columns (DSTCs) consist of an outer tube made of FRP and an inner tube made of steel, with the space between filled with concrete. A significant amount of research has been conducted on hybrid DSTCs with an outer tube made of glass FRP (GFRP), carbon FRP (CFRP), or aramid FRP (AFRP). One important finding of the existing research is that the ductility of the column depends significantly on the rupture strain of the FRP tube, among other factors. Against this background, this paper presents an experimental study where hybrid DSTCs with a large rupture …

Computing Proximal Points Of Convex Functions With Inexact Subgradients, Chayne Planiden, Warren L. Hare Jan 2016

Computing Proximal Points Of Convex Functions With Inexact Subgradients, Chayne Planiden, Warren L. Hare

Faculty of Engineering and Information Sciences - Papers: Part B

Locating proximal points is a component of numerous minimization algorithms. This work focuses on developing a method to find the proximal point of a convex function at a point, given an inexact oracle. Our method assumes that exact function values are at hand, but exact subgradients are either not available or not useful. We use approximate subgradients to build a model of the objective function, and prove that the method converges to the true prox-point within acceptable tolerance. The subgradient g_k used at each step k is such that the distance from g_k to the true subdifferential of the objective …

Characterization Of Angular Detection Dependence Of Prompt Gamma-Rays With Respect To The Bragg Peak In A Water Phantom Using Proton Beam Irradiations, Melek Zarifi, Susanna Guatelli, David Bolst, Brian F. Hutton, Anatoly B. Rosenfeld, Yujin Qi Jan 2016

Characterization Of Angular Detection Dependence Of Prompt Gamma-Rays With Respect To The Bragg Peak In A Water Phantom Using Proton Beam Irradiations, Melek Zarifi, Susanna Guatelli, David Bolst, Brian F. Hutton, Anatoly B. Rosenfeld, Yujin Qi

Faculty of Engineering and Information Sciences - Papers: Part B

The rationale for utilizing the prompt gamma (PG) signal for in vivo proton beam range verification is such that the PG fall-off distribution along the beam path is associated with the dose profile in the Bragg peak (BP) distal fall-off region. Quantitative characterization of this association, particularly with respect to the BP, is of great importance to assess its limitation and aid in the development of a clinically reliable PG imaging system to maximize PG detection. In this work we investigate the angular dependence of PG detection with respect to the BP for in vivo beam range verification in proton …

Circular Dispersive Shock Waves In Colloidal Media, Amirah Azmi, Timothy R. Marchant Jan 2016

Circular Dispersive Shock Waves In Colloidal Media, Amirah Azmi, Timothy R. Marchant

Faculty of Engineering and Information Sciences - Papers: Part B

A dispersive shock wave (DSW), with a circular geometry, is studied in a colloidal medium. The colloidal particle interaction is based on the repulsive theoretical hard sphere model, where a series in the particle density, or packing fraction is used for the compressibility. Experimental results show that the particle interactions are temperature dependent and can be either repulsive or attractive, so the second term in the compressibility series is modified to allow for temperature dependent effects, using a power-law relationship. The governing equation is a focusing nonlinear Schrödinger-type equation with an implicit nonlinearity. The initial jump in electric field amplitude …

The Role And Positioning Of Numeracy In Australian Universities - Does It Matter?, Lesley Wilkins Jan 2016

The Role And Positioning Of Numeracy In Australian Universities - Does It Matter?, Lesley Wilkins

Senior Deputy Vice-Chancellor and Deputy Vice-Chancellor (Education) - Papers

Numeracy has been problematic for practitioners. It has been difficult to de-termine a consistent definition of the term; moreover, there has never been real agreement on its role, or position, within society, or within higher edu-cation. Many students who find mathematics "challenging", but who need to pass a non-specialist mathematics subject in order to graduate, consult Learning Development lecturers in order to obtain assistance with mathemat-ics. Students present with a variety of difficulties ranging from gaps in their schooling, especially senior school mathematics, through to more fundamen-tal mathematics topics. Many students confess to being "bad at maths"; are openly negative …
