The virtual context determines both the visibility status and the required quality of videos of participants. This information can be used to dynamically alter the multicast trees that are formed among clients for the purpose of multimedia …


Improved Geometrical Model Of Fringe Projection Profilometry, Zhengrong Huang, Jiangtao Xi, Yanguang Yu, Qinghua Guo, Limei Song Jan 2014

Improved Geometrical Model Of Fringe Projection Profilometry, Zhengrong Huang, Jiangtao Xi, Yanguang Yu, Qinghua Guo, Limei Song

Faculty of Engineering and Information Sciences - Papers: Part A

The accuracy performance of fringe projection profilometry (FPP) depends on accurate phase-to-height (PTH) mapping and system calibration. The existing PTH mapping is derived based on the condition that the plane formed by axes of camera and projector is perpendicular to the reference plane, and measurement error occurs when the condition is not met. In this paper, a new geometric model for FPP is presented to lift the condition, resulting in a new PTH mapping relationship. The new model involves seven parameters, and a new system calibration method is proposed to determine their values. Experiments are conducted to verify the performance …


On The Efficient Channel State Information Compression And Feedback For Downlink Mimo-Ofdm Systems, Yong Ping Zhang, Peng Wang, Shulan Feng, Philipp Zhang, Sheng Tong Jan 2014

On The Efficient Channel State Information Compression And Feedback For Downlink Mimo-Ofdm Systems, Yong Ping Zhang, Peng Wang, Shulan Feng, Philipp Zhang, Sheng Tong

Faculty of Engineering and Information Sciences - Papers: Part A

This paper is concerned with the efficient compression and feedback of channel state information (CSI) in downlink multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) systems. Inspired by video coding, we propose a novel CSI compression and feedback scheme, referred to as hybrid transform coding (HTC). HTC consists of two coding types, i.e., selective time-domain coding (STDC) and differential time-domain coding (DTDC), which are adopted to exploit the correlation of CSI in both the frequency and time domains. We first develop closed-form expressions for the overhead-distortion performance of these two coding types in HTC. The parameters involved in HTC are then …

Fingerprint Classification Combining Curvelet Transform And Gray-Level Cooccurrence Matrix, Jing Luo, Dan Song, Chunbo Xiu, Shuze Geng, Tingting Dong

Faculty of Engineering and Information Sciences - Papers: Part A

Fingerprint classification is an important indexing scheme to reduce fingerprint matching time for a large database for efficient large-scale identification. The abilities of Curvelet transform capturing directional edges of fingerprint images make the fingerprint suitable to be classified for higher classification accuracy. This paper presents an efficient algorithm for fingerprint classification combining Curvelet transform (CT) and gray-level cooccurrence matrix (GLCM). Firstly, we use fast discrete Curvelet transform warping (FDCT_WARPING) to decompose the original image into five scales Curvelet coefficients and construct the Curvelet filter by Curvelet coefficients relationship at adjacent scales to remove the noise from signals. Secondly, we compute …


Coupled Horizontal-Rocking Vibration Of Partially Embedded Pile Groups And Its Effect On Resonance Of Offshore Wind Turbine Structures, Maosong Huang, Rui Zhong Jan 2014

Coupled Horizontal-Rocking Vibration Of Partially Embedded Pile Groups And Its Effect On Resonance Of Offshore Wind Turbine Structures, Maosong Huang, Rui Zhong

Faculty of Engineering and Information Sciences - Papers: Part A

The partially embedded pile groups bear tremendous moments generated by wind loads due to the large height of the offshore wind turbine structures. It is of great importance to consider the rocking vibration of the foundations in the lateral vibration analyses of wind turbine structures. In order to avoid resonance, which is very dangerous to high structures, the first-order natural frequencies of the wind turbine structures are always designed as away from 1P and 3P (2P) ones, so it is very important to calculate the natural frequencies of the wind turbine structures accurately during the design procedures. At present, the …

Experimental Study On The Validity Of Flow Region Division, Shu-Qing Yang, Yu Han, Pengzhi Lin, Changbo Jiang, Robert Walker

Faculty of Engineering and Information Sciences - Papers: Part A

Einstein first proposed that a river flow can be divided into three parts, corresponding to the banks and its bed, respectively, but he did not explain why the flow is dividable and how to divide the flow, in other words the flow division is only a mathematical treatment to simplify his analysis. Since Einstein's proposition there have been many researches and debates on this topic, many division lines have been proposed, but there is no specially designed experimental research to verify the physical existence of division lines, and these division lines have not been tested against the experimental data. For …

The ANNs were trained, validated, and tested on two databases. The first database contains the experimental compressive strength results of 104 FRP confined rectangular concrete columns. The second database consists of the experimental compressive strain of 69 FRP confined square concrete columns. Furthermore, this study proposes …


Shear Strength Testing Of Glass Fibre Reinforced Thin Spray-On Liner, Qiuqiu Qiao, Jan Nemcik, Ian Porter Jan 2014

Shear Strength Testing Of Glass Fibre Reinforced Thin Spray-On Liner, Qiuqiu Qiao, Jan Nemcik, Ian Porter

Faculty of Engineering and Information Sciences - Papers: Part A

Thin spray-on liners (TSLs) have been attracting increasing attention as an alternative to steel mesh in underground roadway support. In order to investigate the shear strength of glass fibre reinforced TSLs, an improved punch test was developed: the steel ring is replaced by TSL plates and four screws are used to tighten the TSL sample between the clamping plates to ensure stable and symmetrical loading. Four different glass fibre contents were tested to evaluate the effect of glass fibre reinforcement on the shear strength of TSLs. The effect of loading rate was studied. The results suggest that the steel punch …

We demonstrate an all-optical terahertz modulator based on single-layer graphene on germanium (GOG), which can be driven by a 1.55 mu m CWlaser with a low-level photodoping power. Both the static and dynamic THz transmission modulation experiments were carried out. Aspectrally wide-band modulation of the THz transmission is obtained in a frequency range from 0.25 to 1 THz, and a modulation depth of 94% can be achieved if proper pump power is applied. The modulation speed of the modulator was measured to be similar to 200 KHz using a 340 GHz carrier. A theoretical model is proposed for the modulator …

Building Workforce Competencies Through Complex Projects, Andrew Sense, Senevi Kiridena

Faculty of Engineering and Information Sciences - Papers: Part A

This chapter illuminates the current theories and concepts concerning complexity and the project management workforce competencies necessary to deal with it in projects. It exposes the valuable, yet underutilised, opportunities complex projects may present to develop the knowledge and competencies of a workforce to successfully manage complexity within a project space and across an organisation more generally. The theoretical implications of this analysis imply that more research is necessary to establish a framework of competencies that relate appropriately to the levels of complexity within a project. The practice implications are profound since managing complexity in projects requires a more expansive …


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.


Effect Of Ballast Contamination On The Behaviour Of Track Substructure, Nayoma Tennakoon, Buddhima Indraratna, Cholachat Rujikiatkamjorn Jan 2014

Effect Of Ballast Contamination On The Behaviour Of Track Substructure, Nayoma Tennakoon, Buddhima Indraratna, Cholachat Rujikiatkamjorn

Faculty of Engineering and Information Sciences - Papers: Part A

Ballast contamination by subgrade pumping and coal contamination is understood as major cause of track deterioration in many countries over the world. As contamination clogs the ballast voids, the drainage capacity of the track is compromised. Further, lubrication caused by these fines results in reducing load bearing capacity of the ballast layer. In this study, a series of large scale hydraulic conductivity and triaxial tests were performed to study the influence of contamination of ballast on its drainage and shear strength characteristics. Drainage capacity of the contaminated track under different level of contamination was determined, undertaking a numerical analysis using …

Soft Clay Properties For Non-Darcian Radial Drainage With Vacuum Preloading, Based On Rowe Cell Resting, Buddhima Indraratna, Kourosh Kianfar, Cholachat Rujikiatkamjorn, Darshana Perera

Faculty of Engineering and Information Sciences - Papers: Part A

Application of vacuum pressure with prefabricated vertical drains in soft clays is a popular and effective ground improvement method. Application of vacuum pressure via vertical drains generates a negative excess pore water pressure (PWP) resulting in an immediate increase in effective stress. This paper summarises the recent advancements in vacuum preloading based on laboratory studies, using the conventional and modified Rowe cells. Location and the magnitude of the average PWP and degree of consolidation during vacuum preloading are investigated. Based on the laboratory experiments a new radial consolidation model is proposed for vacuum preloading incorporating non-Darcian flow.

Faculty of Engineering and Information Sciences - Papers: Part A

Bothheavy goods vehicles (HGV) and exiting vehicles can significantly affect the entry capacity of a roundabout. However, their effects have not been taken into account in HCM 2000 model.Recently two studies have been carried out to address this issue: 1) Dahl and Lee (2012) proposed an expectation theory based approachto incorporate the effect of HGVs [1]; and2)Qu et al. (2013) deriveda new roundabout capacity model by assuming that each exiting vehicle could provide one entry opportunity for waiting vehicles [2]. In this paper, the two models are integrated using a scenario-based approachtoanalyse the effects of not only exiting vehicles but …


The Pricing Of Credit Default Swaps Under A Generalized Mixed Fractional Brownian Motion, Xinjiang He, Wenting Chen Jan 2014

The Pricing Of Credit Default Swaps Under A Generalized Mixed Fractional Brownian Motion, Xinjiang He, Wenting Chen

Faculty of Engineering and Information Sciences - Papers: Part A

In this paper, we consider the pricing of the CDS (credit default swap) under a GMFBM (generalized mixed fractional Brownian motion) model. As the name suggests, the GMFBM model is indeed a generalization of all the FBM (fractional Brownian motion) models used in the literature, and is proved to be able to effectively capture the long-range dependence of the stock returns. To develop the pricing mechanics of the CDS, we firstly derive a sufficient condition for the market modeled under the GMFBM to be arbitrage free. Then under the risk-neutral assumption, the CDS is fairly priced by investigating the two …

Linear Regression With Nested Errors Using Probability-Linked Data, Klairung Samart, Raymond Chambers Jan 2014

Linear Regression With Nested Errors Using Probability-Linked Data, Klairung Samart, Raymond Chambers

Faculty of Engineering and Information Sciences - Papers: Part A

Probabilistic matching of records is widely used to create linked data sets for use in health science, epidemiological, economic, demographic and sociological research. Clearly, this type of matching can lead to linkage errors, which in turn can lead to bias and increased variability when standard statistical estimation techniques are used with the linked data. In this paper we develop unbiased regression parameter estimates to be used when fitting a linear model with nested errors to probabilistically linked data. Since estimation of variance components is typically an important objective when fitting such a model, we also develop appropriate modifications to standard …

Evolving Formative Assessment For And With Ubiquitous Technologies, Nadine Adams, Anne Porter

Faculty of Engineering and Information Sciences - Papers: Part A

Formative assessment is a vital part of the learning process. It guides student learning and prepares them for summative assessment. The feedback that accompanies formative assessment is valuable for students' learning. The combination of formative assessment and feedback facilitate the development of self-efficacy. Technology is not only changing the way students study and learn but also how assessment is conducted and managed. Globalisation and corporatisation of universities has changed the way academics work and has had an effect on teaching, assessment and feedback. This paper looks at how formative assessment in an enabling mathematics course has been developed to take …


Global Optimization Method For Robust Pricing Of Transportation Networks Under Uncertain Demand, Shuaian Wang, Lauren Gardner, S.Travis Waller Jan 2014

Global Optimization Method For Robust Pricing Of Transportation Networks Under Uncertain Demand, Shuaian Wang, Lauren Gardner, S.Travis Waller

Faculty of Engineering and Information Sciences - Papers: Part A

We extend the existing toll pricing studies with fixed demand to stochastic demand. A new and practical second-best pricing problem with uncertain demand is proposed and formulated as a stochastic mathematical program with equilibrium constraints. In view of the problem structure, we develop a tailored global optimization algorithm. This algorithm incorporates a sample average approximation scheme, a relaxation-strengthening method, and a linearization approach. The proposed global optimization algorithm is applied to three networks: a two-link network, a seven-eleven network and the Sioux-Falls network. The results demonstrate that using a single fixed estimation of future demand may overestimate the future system …


Multi-Stage Compressed Sensing And Wall Clutter Mitigation For Through-The-Wall Radar Image Formation, Fok Hing Chi Tivive, Abdesselam Bouzerdoum, Van Ha Tang Jan 2014

Multi-Stage Compressed Sensing And Wall Clutter Mitigation For Through-The-Wall Radar Image Formation, Fok Hing Chi Tivive, Abdesselam Bouzerdoum, Van Ha Tang

Faculty of Engineering and Information Sciences - Papers: Part A

In this paper, a multi-stage through - The-wall radar imaging technique combining wall clutter mitigation and scene reconstruction is proposed. In the first stage, compressed sensing is applied to compressive measurements to recover the radar signals in the wavelet domain. Then, a subspace projection method is employed to remove the wavelet coefficients associated with the exterior wall reflections. In the second stage, the remaining wavelet coefficients are further compressed using principal component analysis. A compact linear measurement model is then formulated which relates the compressed wavelet coefficients to the image of the scene. Finally, the image reconstruction problem is solved …


Over-Voltage Mitigation Within Distribution Networks With A High Renewable Distributed Generation Penetration, Joel Kennedy, Philip Ciufo, Ashish Agalgaonkar Jan 2014

Over-Voltage Mitigation Within Distribution Networks With A High Renewable Distributed Generation Penetration, Joel Kennedy, Philip Ciufo, Ashish Agalgaonkar

Faculty of Engineering and Information Sciences - Papers: Part A

The rapid growth of grid-connected distributed generation has increased the likelihood of over-voltage occurrences in distribution networks. In recent times, much research has taken place in order to develop a control strategy to mitigate the voltage rise problem. However, most of the published strategies require re-tuning when additional resources are connected, or have a strong dependence on network parameters, such as fault level. This paper proposes a novel over-voltage mitigation scheme that has many advantages not observed in literature. Firstly, the control scheme can integrate with an existing feeder in a plug-and-play fashion. No prior analysis is necessary to configure …


Case Studies On Response Of Laterally Loaded Nonlinear Piles, Wei Dong Guo Jan 2014

Case Studies On Response Of Laterally Loaded Nonlinear Piles, Wei Dong Guo

Faculty of Engineering and Information Sciences - Papers: Part A

Closed-form solutions for laterally loaded free and fixed-head piles in elastic-plastic media have been developed and implemented into a spreadsheet program called GASLFP. Underpinned by a generic limiting force profile (LFP), the solutions offer an expeditious and sufficiently accurate method for predicting response of lateral piles. They also allow parameters to be deduced using measured pile response, as is evident in the study to date on -70 test (elastic) piles. The solutions also well capture the impact of structure nonlinearity of pile body by employing reduced pile bending stiffness (EpIp). The law of the reduction in EpIp, however, needs to …


Limiting Force Profile And Laterally Loaded Rigid Piles In Sand, Hongyu Qin, Wei Dong Guo Jan 2014

Limiting Force Profile And Laterally Loaded Rigid Piles In Sand, Hongyu Qin, Wei Dong Guo

Faculty of Engineering and Information Sciences - Papers: Part A

In this paper, closed-form solutions were used to analyze the response of eight laterally loaded rigid piles obtained from field test, centrifuge test, and 1g laboratory model tests, allowing the modulus of subgrade reaction and the profile of limiting lateral resistance force per unit length (LFP, pu profile) to be back calculated. The study shows that (1) with a constant modulus of subgrade reaction, a linear increasing LFP and elasto-plastic p ~ y curves, the response of laterally loaded rigid piles can be well predicted in the framework of load transfer approach; (2) the gradient of the LFP is 0.64 …

Performance Of Adjustable Speed Drives Subject To Regular Voltage Fluctuations, Kun Zhao, Philip Ciufo, Sarath Perera

Faculty of Engineering and Information Sciences - Papers: Part A

The impact of power quality disturbances on customer equipment has been a topic of interest to equipment manufacturers, electricity utilities, customers and to those involved in the development of electromagnetic compatibility standards. Recently, a new interest has developed in the possible impact of voltage fluctuations on customer equipment because of suggestions to relax voltage fluctuation limits and hence the flicker limits in power systems. With a view to contribute to this understanding, this paper investigates the performance of an adjustable speed drive (ASD) when subjected to sinusoidal regular voltage fluctuations. When the ASD is operating in open loop mode, the …
