Effect Of Pre-Quenching Process On Microstructure And Mechanical Properties In A Nb-Microalloyed Low Carbon Q-P Steel, Jun Zhang, Hua Ding, Jingwei Zhao
Faculty of Engineering and Information Sciences - Papers: Part A
A refined microstructure consisting of martensite and retained austenite at room temperature has been produced in a Nb-microalloyed low carbon Si-Mn steel by a novel heat-treatment, pre-quenching prior to quenching and partitioning processes (Q&Q-P). The results showed that compared with the conventional quenching and partitioning steel the mechanical properties of steel obtained by the novel treatment have been significantly improved, with a good combination of ultimate tensile strength (1000MPa) and total elongation (above 30%). Meanwhile, the volume fraction of retained austenite has been increased. It was found that the improvement of mechanical properties was mainly attributed to the enhanced TRIP …

High performance with stability, easy-handling electrodes, and biofluid-flow controllable system with mechanical strength of the biofuel cell can be considered as the critical issues for future human body implant. These three challenges are sufficiently considered by using the effective platform regarding the high surface area from multi-walled carbon nanotube-conducting polymer with poly(3,4-ethylenedioxythiophene), and size/shape dependent flexible yarn electrodes for the implantation of biofuel cell. High power biofuel cell of mW cm-2 range in physiological condition (low glucose-containing phosphate buffered saline solution and human blood serum) controlling the stirring degree is also first demonstrated for future implantation in this study. Biofuel …
Violent Scene Detection Using A Super Descriptor Tensor Decomposition, Muhammad Rizwan Khokher, Abdesselam Bouzerdoum, Son Lam Phung
Violent Scene Detection Using A Super Descriptor Tensor Decomposition, Muhammad Rizwan Khokher, Abdesselam Bouzerdoum, Son Lam Phung
Faculty of Engineering and Information Sciences - Papers: Part A
This article presents a new method for violent scene detection using super descriptor tensor decomposition. Multi-modal local features comprising auditory and visual features are extracted from Mel-frequency cepstral coefficients (including first and second order derivatives) and refined dense trajectories. There is usually a large number of dense trajectories extracted from a video sequence; some of these trajectories are unnecessary and can affect the accuracy. We propose to refine the dense trajectories by selecting only discriminative trajectories in the region of interest. Visual descriptors consisting of oriented gradient and motion boundary histograms are computed along the refined dense trajectories. In traditional …

Faculty of Engineering and Information Sciences - Papers: Part A
In this paper a new protection scheme for DC traction supply system is introduced, which is known as 'overload protection method'. In this scheme, with the knowledge of the number of traveling trains between two traction substations and the value of current which is drawn from each substation, the occurrence of short circuit fault is detected. The aforementioned data can be extracted and transmitted from railway traffic control system. Recently DDL ('Détection Défaut Lign in French', which means 'Line Fault detection') protection method is used in supply line protection. In this paper, the electrical system of railway system is simulated …

The determination of Region-of-Interest has been re cognised as an important means by which unimportant image content can be identified and exc luded during image compression or image modelling, however existing Region-of-Interest dete ction methods are computationally expensive thus are mostly unsuitable for managing l arge number of images and the compression of images especially for real-time video applicatio ns. This paper therefore proposes an unsupervised algorithm that takes advantage of the high computation speed being offered by Speeded-Up Robust Features (SURF) and Features from Accelerated Segment Test (FAST) to achieve fast and efficient Region-of-Interest detec tion.

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.
Classification Of Micro-Doppler Signatures Of Human Motions Using Log-Gabor Filters, Fok Hing Chi Tivive, Son Lam Phung, Abdesselam Bouzerdoum
Classification Of Micro-Doppler Signatures Of Human Motions Using Log-Gabor Filters, Fok Hing Chi Tivive, Son Lam Phung, Abdesselam Bouzerdoum
Faculty of Engineering and Information Sciences - Papers: Part A
In recent years, Doppler radar has been used as a sensing modality for human gait recognition, due to its ability to operate in adverse weather and penetrate opaque obstacles. Doppler radar captures not only the speed of the target, but also the micro-motions of its moving parts. These micro-motions induce frequency modulations that can be used to characterise the target movements. However, a major challenge in Doppler signal processing is to extract discriminative features from the radar returns for target classification. This study presents a feature extraction method for classification of human motions from the micro-Doppler radar signal. The proposed …
Enhanced Frequency Response Strategy For Pmsg Based Wind Energy Conversion System Using Ultracapacitor In Remote Area Power Supply Systems, Yingjie Tan, Kashem M. Muttaqi
Enhanced Frequency Response Strategy For Pmsg Based Wind Energy Conversion System Using Ultracapacitor In Remote Area Power Supply Systems, Yingjie Tan, Kashem M. Muttaqi
Faculty of Engineering and Information Sciences - Papers: Part A
The high penetration level of wind energy, and non-responsive nature of power electronic interfaced wind energy conversion system (WECS) during frequency variations may create significant stress on conventional generators in a wind-diesel hybrid remote area power supply (RAPS) system. Hence, it is a necessity for WECS to provide frequency support. However, conventional frequency control strategies being used for WECS may impose a severe stress to wind turbines. In this paper, an enhanced frequency response strategy is proposed for the permanent magnet synchronous generator (PMSG) based WECS to regulate RAPS system frequency jointly with its integrated ultracapacitors. The proposed frequency response …
Community Energy Storage For Neutral Voltage Rise Mitigation In Four-Wire Multigrounded Lv Feeders With Unbalanced Solar Pv Allocation, Md Jan E Alam, Kashem M. Muttaqi, Danny Sutanto
Community Energy Storage For Neutral Voltage Rise Mitigation In Four-Wire Multigrounded Lv Feeders With Unbalanced Solar Pv Allocation, Md Jan E Alam, Kashem M. Muttaqi, Danny Sutanto
Faculty of Engineering and Information Sciences - Papers: Part A
The traditional neutral voltage problem in low-voltage (LV) four-wire multigrounded distribution networks can be aggravated due to an unbalanced allocation of one-phase photovoltaic (PV) units. Inherent limitations restrict the performance of the traditional strategies to mitigate the combined effect of load and PV unbalance. To overcome the shortcoming of traditional approaches, a new dynamic mitigation approach using community energy storage (CES) is proposed in this paper. A power balancing algorithm is developed to perform the balancing operation while minimizing power drawn from the CES. A charge/discharge control strategy is developed that will continuously balance and dynamically adjust the power exchange …

Faculty of Engineering and Information Sciences - Papers: Part A
This paper presents a new application of mathematical morphology (MM) operators for low speed slew bearing condition monitoring. The MM operators were used as a signal processing step and feature extraction method for bearing vibration signals. Four basic MM operators; erosion, dilation, closing and opening, were studied. This paper also investigates another potential MM operator, namely gradient operator. Two common time domain features in bearing condition monitoring, namely root mean square (RMS) and kurtosis, were extracted from the processed signal. The study shows that the changes in bearing condition can be clearly detected from the extracted features (RMS and kurtosis) …

Exact Error Performance Analysis Of Binary Space-Time Block Coded Cooperative Communications Systems In Rayleigh Fading Channels, Le Chung Tran, Zixuan Lin, Farzad Safaei, Alfred Mertins, Duy T. Ngo
Faculty of Engineering and Information Sciences - Papers: Part A
Cooperative communications using the Alamouti space-time block code (STBC) has been mentioned intensively. However, to our knowledge, an in-depth error performance analysis for a space-time coded cooperative communications system, where each node acts as both a source node and a relay node for its partner, has not been reported. Intuitively, cooperative communications would not always be better than direct transmission, but only under certain conditions. This paper first derives an exact performance analysis of the Alamouti STBC cooperative communications for a Binary Phase Shift Keying (BPSK) constellation, which could be extended to a higher density modulation scheme. This mathematical analysis …

Rns Arithmetic Approach In Lattice-Based Cryptography: Accelerating The 'Rounding-Off' Core Procedure, Jean-Claude Bajard, Julien Eynard, Nabil Merkiche, Thomas Plantard
Faculty of Engineering and Information Sciences - Papers: Part A
Residue Number Systems (RNS) are naturally considered as an interesting candidate to provide efficient arithmetic for implementations of cryptosystems such as RSA, ECC (Elliptic Curve Cryptography), pairings, etc. More recently, RNS have been used to accelerate fully homomorphic encryption as lattice-based cryptogaphy. In this paper, we present an RNS algorithm resolving the Closest Vector Problem (CVP). This algorithm is particularly efficient for a certain class of lattice basis. It provides a full RNS Babai round-off procedure without any costly conversion into alternative positional number system such as Mixed Radix System (MRS). An optimized Cox-Rower architecture adapted to the proposed algorithm …

Faculty of Engineering and Information Sciences - Papers: Part A
Agricultural soils are the primary anthropogenic source of atmospheric nitrous oxide (N2OO), contributing to global warming and depletion of stratospheric ozone. Biochar addition has shown potential to lower soil N2OO emission, with the mechanisms remaining unclear. We incubated eucalypt biochar (550 °C) - 0, 1 and 5% (w/w) in Ferralsol at 3 water regimes (12, 39 and 54% WFPS) - in a soil column, following gamma irradiation. After N2OO was injected at the base of the soil column, in the 0% biochar control 100% of expected injected N2OO was released into headspace, declining to 67% in the 5% amendment. In …

Macrostrength And Pore Structure Of Coke Subjected To Gasification And Annealing Under Blast Furnace Conditions, Xing Xing, Harold P. Rogers, Guangqing Zhang, Paul Zulli, Oleg Ostrovski
Faculty of Engineering and Information Sciences - Papers: Part A
Metallurgical cokes were subjected to gasification by CO-CO2-N2 gas with blast furnace-like composition-temperature profile to 1400 °C and annealing under N2 at temperature up to 2000 °C. The degradation of coke strength following reaction and annealing was characterised using tensile testing. Both gasification and annealing decreased the mechanical strength of coke. Degradation of all examined cokes by gasification at 1400 °C was stronger in comparison with annealing at the same temperature.
Evaluating The Environmental Performance Of Indoor Plants In Buildings, Georgios Kokogiannakis, Paul Cooper
Evaluating The Environmental Performance Of Indoor Plants In Buildings, Georgios Kokogiannakis, Paul Cooper
Faculty of Engineering and Information Sciences - Papers: Part A
The effect of indoor plants on indoor environmental conditions is often underestimated or ignored while undertaking building simulation performance assessments. The literature suggests that regularly irrigated plants will evaporate and transpire, and as a result they could alter the humidity, temperature and CO2 concentration inside buildings. Indoor plants could in some cases also affect the amount of solar radiation falling on surfaces, but relevant shading claculations would require adequate geometrical definitions of the plants in relation to their position in building spaces. This paper exlicates a methodology for representing indoor plants in whole building simulation.

Tibetan Word Sense Disambiguation Based On A Semantic Knowledge Network Diagram, Lirong Qiu, Xinmin Jiang, Renqiang Ling
Faculty of Engineering and Information Sciences - Papers: Part A
The method based on semantic knowledge is the most dynamic research direction in rule-based techniques. This method has been proven effective in studying English and Chinese word sense disambiguation. This study proposes two methods for selecting the correct Chinese meaning of Tibetan ambiguous words from Tibetan sentences in Tibetan-Chinese parallel corpora using semantic knowledge from HowNet and translation information from the aforementioned corpora. We can use these methods to build Tibetan-Chinese parallel corpora with word sense tagging. The two proposed methods are 1) the word sense disambiguation method based on HowNet and Tibetan-Chinese parallel corpora, and; 2) the semantic knowledge-based …
Experimental Investigation Of Coal-Fouled Ballast Stabilised With Geogrid, N T. Ngo, C Rujikiatkamjorn, B Indraratna
Experimental Investigation Of Coal-Fouled Ballast Stabilised With Geogrid, N T. Ngo, C Rujikiatkamjorn, B Indraratna
Faculty of Engineering and Information Sciences - Papers: Part A
This paper presents the results of an experimental study of coal-fouled ballast reinforced with geogrid, at various degrees of fouling and subjected to cyclic loading. A novel Track Process Simulation Testing Apparatus was used to realistically simulate fouled rail track conditions. The laboratory results demonstrated that coal fines acted as a lubricant, causing ballast aggregates to displace and rotate and, as a result, increase the deformation of ballast. However, coal fines also reduced ballast breakage somewhat because they fill the voids between the ballast particles and coat surface of ballast aggregates which reduce the inter-particle attrition. The placement of a …

Test case selection is a fundamental issue in software testing, and has generated a large body of research, especially with regards to the effectiveness of random testing (RT), where test cases are randomly selected from the software’s input domain. In this paper, we revisit three of our previous studies. The first study investigated a sufficient condition for partition testing (PT) to outperform RT, and …
Behavior Of Concrete-Filled Frp Tubes Under Cyclic Axial Compression, B Zhang, T Yu, J G. Teng
Behavior Of Concrete-Filled Frp Tubes Under Cyclic Axial Compression, B Zhang, T Yu, J G. Teng
Faculty of Engineering and Information Sciences - Papers: Part A
Concrete-filled fiber-reinforced polymer (FRP) tubes (CFFTs) are an attractive form of hybrid compression members incorporating FRP. CFFTs have several advantages over traditional column forms, including their excellent corrosion resistance and ductility. Much research has been conducted on CFFTs over recent years, but no systematic experimental study has been concerned with the cyclic axial compressive behavior of CFFTs with a filament-wound FRP tube; such studies are needed for the development of a cyclic stress-strain model for the concrete in CFFTs. This paper therefore presents an experimental study on the behavior of circular CFFTs under cyclic axial compression. The experimental program included …
Uct-Kirchberg Algebras Have Nuclear Dimension One, Efren Ruiz, Aidan Sims, Adam P. Sorensen
Uct-Kirchberg Algebras Have Nuclear Dimension One, Efren Ruiz, Aidan Sims, Adam P. Sorensen
Faculty of Engineering and Information Sciences - Papers: Part A
We prove that every Kirchberg algebra in the UCT class has nuclear dimension 1. We first show that Kirchberg 2-graph algebras with trivial K0 and finite K1 have nuclear dimension 1 by adapting a technique developed by Winter and Zacharias for Cuntz algebras. We then prove that every Kirchberg algebra in the UCT class is a direct limit of 2-graph algebras to obtain our main theorem.

Comparative Analysis Of The Secondary Electron Yield From Carbon Nanoparticles And Pure Water Medium, Alexey Verkhovtsev, Sally Mckinnon, Pablo De Vera, Eugene Surdutovich, Susanna Guatelli, Andrei V. Korol, Anatoly Rosenfeld, Andrey V. Solov'yov
Faculty of Engineering and Information Sciences - Papers: Part A
The production of secondary electrons generated by carbon nanoparticles and pure water medium irradiated by fast protons is studied by means of model approaches and Monte Carlo simulations. It is demonstrated that due to a prominent collective response to an external field, the nanoparticles embedded in the medium enhance the yield of low-energy electrons. The maximal enhancement is observed for electrons in the energy range where plasmons, which are excited in the nanoparticles, play the dominant role. Electron yield from a solid carbon nanoparticle composed of fullerite, a crystalline form of C-60 fullerene, is demonstrated to be several times higher …

High Temperature Dislocation Structure And Nbc Precipitation In Three Ni-Fe-Nb-C Model Alloys, Andrii Kostryzhev, Parvez Mannan, Olexandra Marenych
Faculty of Engineering and Information Sciences - Papers: Part A
In this original work, the dislocation structure and NbC precipitation were investigated in three Ni-based alloys (70Ni-Fe-0.331Nb-0.040C, 70Ni-Fe-0.851Nb-0.114C and 70Ni-Fe-1.420Nb-0.157C, wt%) thermomechanically processed in the temperature range of 1250-1075 °C. The dislocation structure inhomogeneity (dislocation networks and cell walls), which we observed in the middle and high Nb+C alloys, resulted from the dislocation pile-ups in the vicinity of >200 nm NbC particles. The dislocation density around >200 nm particles exceeded the average values by 5-7 times, and that in the cell walls might exceed the average values by 10 times. Twins and stacking faults were observed in all alloys after …

Fundamental understanding of membrane fouling in osmosis-driven membrane processes is important for further deployment of this emerging technology in desalination and wastewater reuse. In this study, we investigated the role of pressure in organic fouling and reversibility in forward osmosis (FO) and reverse osmosis (RO) using alginate as a model organic foulant. Varying contributions of pressure (i.e., osmotic versus hydraulic) to the overall driving force were realized in forward osmosis (FO), pressure-assisted FO (PFO), and reverse osmosis (RO) experiments, while the same total driving force for water permeation was applied. Confocal laser scanning microscopy was used to examine alginate fouling …

A polyurethane hydrogel based touch sensor with high transparency and conformability is demonstrated. Polyurethane hydrogels swollen with various electrolytes were compressed at a pressure of 30 kPa, simulating a fingertap on a conventional touch screen device. Unlike ionic polymer metal composite and conducting polymer trilayer sensors, where electrodes render the sensors opaque and relatively rigid, the electrodes used in this work are metal wires or strips, separated from each other by regions of transparent film, enabling transparency and compliance. The voltages and currents observed when the perturbation is above one electrode are on the order of 10(-2) V and 10(-7) …

Development Of An Mre Adaptive Tuned Vibration Absorber With Self-Sensing Capability, Shuaishuai Sun, Jian Yang, Weihua Li, Huaxia Deng, Haiping Du, Gursel Alici
Faculty of Engineering and Information Sciences - Papers: Part A
In this paper, self-sensing technology was introduced into an adaptive tuned vibration absorber, incorporating a laminated magnetorheological elastomer (MRE) structure, a hybrid magnetic system and a self-sensing component. The adoption of the laminated MRE structure and the hybrid magnetic system enables the absorber to have higher lateral flexibility and a wider effective frequency range. The integration of the self-sensing capability allows the absorber to operate without sensors and, at the same time, greatly reduces costs, required space and maintenance. A series of experiments were conducted to measure the frequency shift property, to verify the self-sensing capability and to evaluate its …
