Tunable Particle Focusing In A Straight Channel With Symmetric Semicircle Obstacle Arrays Using Electrophoresis-Modified Inertial Effects, Dan Yuan, Chao Pan, Jun Zhang, Sheng Yan, Qianbin Zhao, Gursel Alici, Weihua Li Jan 2016

Tunable Particle Focusing In A Straight Channel With Symmetric Semicircle Obstacle Arrays Using Electrophoresis-Modified Inertial Effects, Dan Yuan, Chao Pan, Jun Zhang, Sheng Yan, Qianbin Zhao, Gursel Alici, Weihua Li

Faculty of Engineering and Information Sciences - Papers: Part A

In this work, a novel microfluidic platform for tunable particle focusing in a straight channel with symmetric semicircle obstacle arrays using electrophoresis (EP)-modified inertial effects was presented. By exerting an EP force on the charged microparticles, a relative velocity gap between microspheres and fluid in a straight channel with symmetric semicircle obstacle arrays was implemented. The relative velocity and fluid shear will induce shear-slip lift force (Saffman lift force) perpendicular to the mainstream direction. Therefore, the focusing pattern can be altered using the electrophoresis-induced Saffman force. The effects of electric field direction, flow rate, electric field magnitude, and particle ...

Effects Of Hydraulic Pressure On Wrinkling And Earing In Micro Hydro Deep Drawing Of Sus304 Circular Cups, Liang Luo, Dongbin Wei, Xiaogang Wang, Cunlong Zhou, Qingxue Huang, Jianzhong Xu, Di Wu, Zhengyi Jiang

Faculty of Engineering and Information Sciences - Papers: Part A

Influences of hydraulic pressure on forming features in micro hydro deep drawing are different from those in normal drawing due to the small size of specimens. In this study, micro hydro deep drawing of SUS304 sheets was carried out in order to study the impacts of the hydraulic pressure on the quality of the drawn cup. Experimental results indicate that there is a critical hydraulic pressure range from 3 to 6 % of the blank's initial yield stress, where wrinkling and earing development trends change twice. The wrinkling and the earing of the drawn cup also reach their local extremes ...


Effects Of Sintering Materials And Gas Conditions On Formation Of Silico-Ferrites Of Calcium And Aluminium During Iron Ore Sintering, Zhe Wang, David J. Pinson, Sheng Chew, Brian J. Monaghan, Mark Pownceby, Nathan A.S. Webster, Harold P. Rogers, Guangqing Zhang Jan 2016

Faculty of Engineering and Information Sciences - Papers: Part A

Silico-ferrites of calcium and aluminium (SFCA) are desirable phases in a high quality iron ore sinter product. The effects of sintering temperature, CaO/SiO2 ratio, sintering gas atmosphere and cooling procedure on the phase composition of sintered specimens from an industrial sinter blend were examined with focus on the formation of SFCA phases. The proportions of mineral phases in specimens sintered at 1 250-1 325°C were quantitatively examined using image analysis. SFCA can be formed at low temperatures by solid state reactions, the formation of which was enhanced by increasing temperature. Further increasing sintering temperature promoted the reduction of ...

Based on the detected performance, instant visual, auditory, electrotactile and vibrotactile biofeedback could be provided to augment the somatosensory input and enhance balance control. This review aims to synthesize the research examining the effect of biofeedback systems, with wearable inertial motion sensors and force sensors, on balance performance. Randomized and non-randomized clinical trials were included in this review. All studies ...


Synchrotron Activation Radiotherapy: Effects Of Dose-Rate And Energy Spectra To Tantalum Oxide Nanoparticles Selective Tumour Cell Radiosensitization Enhancement, Elette Engels, Michael L. F Lerch, Moeava Tehei, Konstantin K. Konstantinov, Susanna Guatelli, Anatoly B. Rosenfeld, Stephanie Corde Jan 2016

Faculty of Engineering and Information Sciences - Papers: Part A

Synchrotron radiation is unique in its ability to deliver dose at high dose rates using kiloelectronvolt photons. We are investigating the use of Tantalum pentoxide (Ta2O5) nano-structured particles (NSPs) that are to date unexplored in synchrotron radiation fields as they have high atomic number (Z=73) are biocompatible and are therefore potential radio sensitizers. We exposed cell culture flasks containing 9L gliosarcoma tumour cells or Madin-Darby Canine Kidney (MDCK) non-tumour cells to the NSPs and treated the cells using a broad synchrotron beam (140 keV median energy; average dose rate of 50 Gy/s) at the Australian Synchrotron. We compare ...

Etching Process Related Changes And Effects On Solid-Core Single-Mode Polymer Optical Fiber Grating, Kishore Bhowmik, Gang-Ding Peng, Yanhua Luo, Eliathamby Ambikairajah, Vedran Lovric, William R. Walsh, Ginu Rajan

Faculty of Engineering and Information Sciences - Papers: Part A

Etching process related material and mechanical changes on solid-core single-mode polymer optical fiber (POF) and their influence on the characteristic properties of polymer fiber Bragg gratings (PFBGs) are studied. A poly(methyl methacrylate)-based POF is etched to different diameters, and it is experimentally demonstrated that etching can lead to a change in the Young's modulus of the fiber. It is found that etching process induced material changes of the polymer fiber can enhance the reflectivity and inherent sensitivity of PFBGs. It is demonstrated that gratings based on etched POF exhibit higher reflectivity with a shorter exposure time compared ...

Effects Of Salinity Build-Up On The Performance Of An Anaerobic Membrane Bioreactor Regarding Basic Water Quality Parameters And Removal Of Trace Organic Contaminants, Xiaoye Song, James A. Mcdonald, William E. Price, Stuart J. Khan, Faisal I. Hai, Hao H. Ngo, Wenshan Guo, Long D. Nghiem

Faculty of Engineering and Information Sciences - Papers: Part A

The effects of elevated inorganic salt concentration on anaerobic membrane bioreactor (AnMBR) treatment regarding basic biological performance and trace organic contaminant (TrOC) removal were investigated. A set of 33 TrOCs were selected to represent pharmaceuticals, steroids, and pesticides in municipal wastewater. Results show potential adverse effects of increase in the bioreactor salinity to 15 g/L (as NaCl) on the performance of AnMBR with respect to chemical oxygen demand removal, biogas production, and the removal of most hydrophilic TrOCs. Furthermore, a decrease in biomass production was observed as salinity in the bioreactor increased. The removal of most hydrophobic TrOCs was ...


The Effects Of Vacuum Annealing Temperatures On The Microstructure, Mechanical Properties And Electrical Resistivity Of Mg-3al-1zn Alloy Ribbons, Fenghua Chen, Qingxue Huang, Zhengyi Jiang, Jingwei Zhao, Binyu Sun, Yugui Li Jan 2015

The Effects Of Vacuum Annealing Temperatures On The Microstructure, Mechanical Properties And Electrical Resistivity Of Mg-3al-1zn Alloy Ribbons, Fenghua Chen, Qingxue Huang, Zhengyi Jiang, Jingwei Zhao, Binyu Sun, Yugui Li

Faculty of Engineering and Information Sciences - Papers: Part A

This paper investigates the influence of vacuum annealing temperature on the microstructure, mechanical properties and electrical resistivity of Mg-3Al-1Zn rapid solidification (RS) magnesium ribbons. The results indicate that when the annealing temperature is increased, the grain size of the ribbons is dramatically reduced from 10 to 1 μm. The highest break stress and micro-hardness is obtained at 673 K. These effects are ascribed to the dispersion strengthening caused by the high amount of fine nanoparticles distributed in the material. Electrical resistivity-temperature (ρ-T) curves have been used to provide useful information about the effects of the annealing temperature on the grain ...

Effects Of Grain Boundaries In Oxide Scale On Tribological Properties Of Nanoparticles Lubrication, Xianglong Yu, Zhengyi Jiang, Jingwei Zhao, Dongbin Wei, Cunlong Zhou, Qingxue Huang

Faculty of Engineering and Information Sciences - Papers: Part A

The characters of grain boundaries in oxide layers formed on substrates influence adhesion and friction behaviour, surface fracture and wear during high temperature steel processing. In this work, an electron backscattered diffraction (EBSD) analysis was conducted to investigate the role of surface grain boundary and orientation in magnetite (Fe3O4)/haematite (α-Fe2O3) scale during hot rolling, and further evaluate their effects on tribological properties of water-based nanoparticles lubrication. The results demonstrate that Fe3O4 (100) plane is strongly sensitive to the surface characteristics as the minimisation of surface energy. Coincident site lattice (CSL ...

Model-Based Correction For Scatter And Tailing Effects In Simultaneous 99mtc And 123i Imaging For A Cdznte Cardiac Spect Camera, Maria Holstensson, Kjell Erlandsson, Gavin Poludniowski, Simona Ben-Haim, Brian F. Hutton

Faculty of Engineering and Information Sciences - Papers: Part A

2015 Institute of Physics and Engineering in Medicine. An advantage of semiconductor-based dedicated cardiac single photon emission computed tomography (SPECT) cameras when compared to conventional Anger cameras is superior energy resolution. This provides the potential for improved separation of the photopeaks in dual radionuclide imaging, such as combined use of 99mTc and 123I . There is, however, the added complexity of tailing effects in the detectors that must be accounted for. In this paper we present a model-based correction algorithm which extracts the useful primary counts of 99mTc and 123I from projection data. Equations describing the in-patient ...


A Promising Set Of Spreading Sequences To Mitigate Mai Effects In Mimo Sts Systems, Anh Tuyen Le, Le Chung Tran, Prashan Premaratne, David Stirling, Beata J. Wysocki, Tadeusz A. Wysocki, Peter J. Vial Jan 2015

A Promising Set Of Spreading Sequences To Mitigate Mai Effects In Mimo Sts Systems, Anh Tuyen Le, Le Chung Tran, Prashan Premaratne, David Stirling, Beata J. Wysocki, Tadeusz A. Wysocki, Peter J. Vial

Faculty of Engineering and Information Sciences - Papers: Part A

Multiple input, Multiple output space time spreading (MIMO STS) system is a scheme which can provide full diversity gain without extra resource requirements. However, its performance degrades significantly when multiple access interference (MAI) occurs. In order to mitigate MAI effects, we propose a criterion to build a promising set of combination of spreading sequences for users. Simulation results show that the average BER performance of users using this promising set is about thirty percent lower than that of users using another set in case of 64 chip length Walsh-Hadamard code.

Effects Of Mesh Size And Escape Gaps On Discarding In An Australian Giant Mud Crab (Scylla Serrata) Trap Fishery, Matt Broadhurst, Paul Butcher, Brian R. Cullis Jan 2014

Effects Of Mesh Size And Escape Gaps On Discarding In An Australian Giant Mud Crab (Scylla Serrata) Trap Fishery, Matt Broadhurst, Paul Butcher, Brian R. Cullis

Faculty of Engineering and Information Sciences - Papers: Part A

In response to concerns over excessive discarding from Australian recreational round traps (with four funnel entrances) used to target giant mud crabs, Scylla serrata, an experiment was done to assess the independent and cumulative utility of paired, bottom-located horizontal escape gaps (46x120 mm) and increasing mesh size (from 51 to 101 mm). Compared to conventional traps comprising 51-mm mesh throughout, those with the same mesh size and escape gaps caught significantly fewer (by 95%) undersize (- CL) crabs while maintaining legal catches. Traps made from 101-mm mesh (but with the same funnel entrances as conventional designs) and with and without escape ...


The Effects Of Feed Solution Temperature On Pore Size And Trace Organic Contaminant Rejection By The Nanofiltration Membrane Nf270, Hai Quang Dang, William E. Price, Long Duc Nghiem Jan 2014

The Effects Of Feed Solution Temperature On Pore Size And Trace Organic Contaminant Rejection By The Nanofiltration Membrane Nf270, Hai Quang Dang, William E. Price, Long Duc Nghiem

Faculty of Engineering and Information Sciences - Papers: Part A

This study investigated the effect of feed temperature on membrane pore size and the rejection of trace organic contaminants (TrOCs) by the nanofiltration (NF) membrane NF270. Filtration experiments were conducted using a cross flow membrane system at 20, 30 and 40 C. The membrane pore radius was estimated using the pore hindrance transport model at each temperature and the rejection data of three reference organic solutes (i.e. erythritol, xylose and glucose) experimentally obtained in this study. The results suggest that the pore size of an NF membrane is dependent on the feed solution temperature. An increase in the feed ...

Effects Of Annealing On Microstructure And Microstrength Of Metallurgical Coke, Xing Xing, Guangqing Zhang, Harold Rogers, Paul Zulli, Oleg Ostrovski

Faculty of Engineering and Information Sciences - Papers: Part A

Two metallurgical cokes were heat treated at 1673 K to 2273 K (1400 degrees celsius to 2000 degrees celsius) in a nitrogen atmosphere. The effect of heat treatment on the microstructure and microstrength of metallurgical cokes was characterized using X-ray diffraction, Raman spectroscopy, and ultramicroindentation. In the process of heat treatment, the microstructure of the metallurgical cokes transformed toward the graphite structure. Raman spectroscopy of reactive maceral-derived component (RMDC) and inert maceral-derived component (IMDC) indicated that the graphitisation degree of the RMDC was slightly lower than that of the IMDC in the original cokes; however graphitisation of the RMDC progressed ...

Faculty of Engineering and Information Sciences - Papers: Part A

This study investigated effects of mature compost on gaseous emissions during composting using pig manure amended with corn stalks. Apart from a control treatment, three treatments were conducted with the addition of 5% (wet weight of raw materials) of mature compost: (a) mixing raw materials with mature compost at the beginning of composting; (b) covering raw materials with mature compost throughout the experimental period; and (c) covering raw materials with mature compost at the start of composting, but incorporating it into composting pile on day 6 of composting. Mature compost used for the last treatment was inoculated with 2% (wet ...


Effects Of Chemical Preservation On Flux And Solute Rejection By Reverse Osmosis Membranes, Kha L. Tu, Allan Chivas, Long D. Nghiem Jan 2014

Effects Of Chemical Preservation On Flux And Solute Rejection By Reverse Osmosis Membranes, Kha L. Tu, Allan Chivas, Long D. Nghiem

Faculty of Engineering and Information Sciences - Papers: Part A

This study investigates the impacts of chemical preservation on the performance of polyamide reverse osmosis membranes with respect to water permeability and solute rejection. Three preservative chemicals, namely formaldehyde, sodium metabisulfite, and 2,2-Dibromo-3-Nitrilopropionamide, were evaluated for membrane preservation at pH 3 and 7. Experimental data show that chemical preservation may change the membrane surface properties, and consequently water permeability and solute rejection efficiency of the membrane are negatively impacted. The impacts of preservation on boron rejection and sodium rejection are similar in magnitude and more significant than those on water permeability. The results indicate that the impact of chemical ...


Effects Of Tungsten On The Hydrogen Embrittlement Behaviour Of Microalloyed Steels, Jingwei Zhao, Zhengyi Jiang, Chong Soo Lee Jan 2014

Effects Of Tungsten On The Hydrogen Embrittlement Behaviour Of Microalloyed Steels, Jingwei Zhao, Zhengyi Jiang, Chong Soo Lee

Faculty of Engineering and Information Sciences - Papers: Part A

The effects of tungsten (W) additions (0, 0.1, 0.5 and 1 wt.%) on the hydrogen embrittlement behaviour of microalloyed steels were systematically investigated by means of slow strain rate tests on circumferentially notched cylindrical specimens, and the mechanism of hydrogen-induced embrittlement was discussed. W addition is found to increase the activation energy of hydrogen desorption. Microstructural features affect the hydrogen embrittlement behaviour and fracture modes of microalloyed steels. It is suggested that the hydrogen-induced embrittlement in the studied microalloyed steels with different W additions is caused by the combined effects of decohesion and internal pressure in the presence ...


Effects Of Hydrogen On The Critical Conditions For Dynamic Recrystallization Of Titanium Alloy During Hot Deformation, Jingwei Zhao, Hua Ding, Zhengyi Jiang, Dongbin Wei, Kezhi Linghu Jan 2014

Effects Of Hydrogen On The Critical Conditions For Dynamic Recrystallization Of Titanium Alloy During Hot Deformation, Jingwei Zhao, Hua Ding, Zhengyi Jiang, Dongbin Wei, Kezhi Linghu

Faculty of Engineering and Information Sciences - Papers: Part A

Hot deformation tests were performed to study the flow behavior and microstructural evolution of a Ti600 titanium alloy with different hydrogen contents. The effects of hydrogen on the critical conditions for the initiation of dynamic recrystallization (DRX) were investigated. The DRX kinetics models of hydrogenated Ti600 alloy were developed, and the DRX volume fractions were quantified under different deformation conditions. The results indicate that the addition of proper hydrogen (no greater than 0.3 pct) benefits the decrease of both the critical stress and critical strain for the initiation of DRX. The critical stress and critical strain are dependent linearly ...


Effects Of Temperature And Strain Rate On Microstructure And Mechanical Properties Of High Chromium Cast Iron/Low Carbon Steel Bimetal Prepared By Hot Diffusion-Compression Bonding, Xingjian Gao, Zhengyi Jiang, Dongbin Wei, Sihai Jiao, Dengfu Chen, Jianzhong Xu, Xiaoming Zhang, Dianyao Gong Jan 2014

Effects Of Temperature And Strain Rate On Microstructure And Mechanical Properties Of High Chromium Cast Iron/Low Carbon Steel Bimetal Prepared By Hot Diffusion-Compression Bonding, Xingjian Gao, Zhengyi Jiang, Dongbin Wei, Sihai Jiao, Dengfu Chen, Jianzhong Xu, Xiaoming Zhang, Dianyao Gong

Faculty of Engineering and Information Sciences - Papers: Part A

The objective of this study is to develop a hot diffusion-compression bonding process for cladding low carbon steel (LCS) to high chromium cast iron (HCCI) in solid-state. The influence of temperature (950-1150 degrees C) and strain rate (0.001-1 s (1)) on microstructure, hardness and bond strength of the HCCI/LCS bimetal were investigated. The interface microstructure reveals that the unbonded region can only be found for 950 degrees C due to lack of diffusion, while the intergrowth between the constituent metals occurred at and above 1100 degrees C. When bonding temperature increases to 1150 degrees C, a carbide-free zone ...


A Novel Approach To Mineral Effects On Coke Reactivity, Brian Monaghan, Apsara Jayasekara, Raymond Longbottom Jan 2014

A Novel Approach To Mineral Effects On Coke Reactivity, Brian Monaghan, Apsara Jayasekara, Raymond Longbottom

Faculty of Engineering and Information Sciences - Papers: Part A

A coke analogue has been developed to evaluate mineral effects on coke reactivity. Elucidation of the effects of minerals on coke reactivity has proved difficult due to the complex and heterogeneous nature of industrial coke and the potential non-additive effects of minerals on coke reactivity. The coke analogue addresses this complexity and heterogeneity through control of its mineralogy, porosity and carbon structures. Recent studies have shown the analogue is capable of discriminating individual mineral effects on coke reactivity. In this paper the reaction mechanism of the analogues reactivity in CO2 is assessed and compared with that of industrial coke.


A Cross-Cultural Study Of Intrusiveness And Fluency Effects Of Web Ads, Xinwei Wang, Tingru Cui, Hock Hai Teo Jan 2014

A Cross-Cultural Study Of Intrusiveness And Fluency Effects Of Web Ads, Xinwei Wang, Tingru Cui, Hock Hai Teo

Faculty of Engineering and Information Sciences - Papers: Part A

Advertising online has increasingly become an important marketing strategy. Along with the rising ad dollars invested on the web, marketers have also devised more powerful ad delivery tactics to garner online consumers' attention. These powerful online advertising tactics may result in intrusiveness perceptions and processing fluency effects. As Westerners tend to focus on the focal object whereas East Asians tend to pay attention to the focal object and contextual background simultaneously when processing a visual scene, East Asians' and Westerners' culturally divergent visual processing styles would lead them to develop varying intrusiveness perceptions and experience differential processing fluency when exposed ...

On The Effects Of Spreading Sequences Over Mimo Systems, Tianle Liu, David A. Stirling, Le Chung Tran, Tadeusz A. Wysocki, Beata J. Wysocki, Prashan Dissanayake Mudiyanselage,, Peter James Vial

Faculty of Engineering and Information Sciences - Papers: Part A

In this paper, we develop a Software Defined Radio (SDR) test bed to evaluate the Multiple Access Interference (MAI) effects over SISO and 2 x 1MIMO systems. It can be observed that under asynchronous transmissions, the Gold code leads to the best performance over both systems due to the fact that it has the best correlation properties. We also find the MAI effects in terms of the spreading sequences pairs on MIMO-STS systems. We propose a criterion for selecting promising spreading sequences for MIMO systems. Based on the measured results, we identify pairs of spreading sequences which have improved BER ...

Predicting Additive And Non-Additive Genetic Effects From Trials Where Traits Are Affected By Interplot Competition, Colleen H. Hunt, Alison B. Smith, David R. Jordan, Brian R. Cullis

Faculty of Engineering and Information Sciences - Papers: Part A

There are two key types of selection in a plant breeding program, namely selection of hybrids for potential commercial use and the selection of parents for use in future breeding. Oakey et al. (in Theoretical and Applied Genetics 113, 809-819, 2006) showed how both of these aims could be achieved using pedigree information in a mixed model analysis in order to partition genetic effects into additive and non-additive effects. Their approach was developed for field trial data subject to spatial variation. In this paper we extend the approach for data from trials subject to interplot competition. We show how the ...

Effects Of Tungsten Addition On The Microstructure And Mechanical Properties Of Microalloyed Forging Steels, Jingwei Zhao, Taekyung Lee, Jeong Hun Lee, Zhengyi Jiang, Chong Soo Lee

Faculty of Engineering and Information Sciences - Papers: Part A

In the current study, the effects of tungsten (W) addition on the microstructure, hardness, and room/low [223 K and 173 K (-50 C and -100 C)] temperature tensile properties of microalloyed forging steels were systematically investigated. Four kinds of steel specimens were produced by varying the W additions (0, 0.1, 0.5, and 1 wt pct). The microstructure showed that the addition of W does not have any noticeable effect on the amount of precipitates. The precipitates in W-containing steels were all rich in W, and the W concentration in the precipitates increased with the increasing W content ...

Effects Of Tungsten On Continuous Cooling Transformation Characteristics Of Microalloyed Steels, Jingwei Zhao, Zhengyi Jiang, Ji Soo Kim, Chong Soo Lee

Faculty of Engineering and Information Sciences - Papers: Part A

Continuous cooling transformation (CCT) characteristics of microalloyed steels with different tungsten (W) contents (0, 0.1 and 1. wt.%) were investigated to obtain the necessary information for heat treatment of these steels. The effects of W addition on the sizes of prior austenite grains and precipitates were analysed. CCT diagrams were obtained by varying the cooling rates from 0.1 to 120. °C/s. Transformation characteristics were determined by using dilatometer test, microscopic observation and hardness measurement. The results showed that W had a positive effect on the refinement of prior austenite grains and precipitates. The CCT diagrams exhibited that ...


Shear Lag And Eccentricity Effects Of Bolted Connections In Cold-Formed Steel Sections, Lip H. Teh, Veysel Yazici Jan 2013

Shear Lag And Eccentricity Effects Of Bolted Connections In Cold-Formed Steel Sections, Lip H. Teh, Veysel Yazici

Faculty of Engineering and Information Sciences - Papers: Part A

This paper examines the "three factors" approach previously presented by the senior author for determining the net section efficiency of a bolted cold-formed steel open profile. One objective is to ascertain that the net section efficiency is governed by three factors: the in-plane shear lag associated with stress concentration around a bolt hole that is also present in a flat sheet, the out-of-plane shear lag that is also present in a bi-symmetric I-section bolted at the flanges only, and the bending moment arising from the connection eccentricity with respect to the neutral axis. This paper presents the test results of ...
