Performance Evaluation Of Square High Strength Concrete (Hsc) Columns Reinforced With Steel Equal Angle (Sea) Sections Under Axial Compression, Ayoob Ibrahim, M Neaz Sheikh, Muhammad N. S Hadi
Faculty of Engineering and Information Sciences - Papers: Part B
This paper reports the results of an experimental investigation on the behaviour of square High Strength Concrete (HSC) columns reinforced longitudinally with either steel bars or Steel Equal Angle (SEA) sections under concentric axial compression. The use of SEA sections as longitudinal reinforcement may enhance the load carrying capacity and ductility of concrete columns. These enhancements are because for a given cross-sectional area, a SEA section has a higher second moment of area and radius gyration than a steel bar. Also, the SEA sections provide a greater confinement area for the concrete core of columns. A total of 6 column β¦

Increased Genomic Prediction Accuracy In Wheat Breeding Using A Large Australian Panel, Adam Norman, J D. Taylor, Emi Tanaka, Paul Telfer, James Edwards, Jean-Pierre Martinant, Haydn Kuchel
Faculty of Engineering and Information Sciences - Papers: Part B
Key message: Genomic prediction accuracy within a large panel was found to be substantially higher than that previously observed in smaller populations, and also higher than QTL-based prediction.Abstract: In recent years, genomic selection for wheat breeding has been widely studied, but this has typically been restricted to population sizes under 1000 individuals. To assess its efficacy in germplasm representative of commercial breeding programmes, we used a panel of 10,375 Australian wheat breeding lines to investigate the accuracy of genomic prediction for grain yield, physical grain quality and other physiological traits. To achieve this, the complete panel was phenotyped in a β¦
Exact Solutions Of The Richards Equation With Nonlinear Plant-Root Extraction, Philip Broadbridge, Edoardo Daly, Joanna M. Goard
Exact Solutions Of The Richards Equation With Nonlinear Plant-Root Extraction, Philip Broadbridge, Edoardo Daly, Joanna M. Goard
Faculty of Engineering and Information Sciences - Papers: Part B
The Richards equation, commonly used to model water flow in unsaturated soils, is highly nonlinear, thus making it very challenging to solve analytically for situations meaningful in practical applications. The inclusion of realistic forms of root-water uptake rates in this equation adds complications in deriving exact solutions. This study provides for the first time analytical solutions of the Richards equation with a sink term nonlinearly dependent on soil water content. These solutions are applied to irrigation furrows, using Cartesian coordinates, and irrigation from a circular plate, in cylindrical coordinates.
A Psychoacoustic-Based Multiple Audio Object Coding Approach Via Intra-Object Sparsity, Maoshen Jia, Jiaming Zhang, Changchun Bao, Xiguang Zheng
A Psychoacoustic-Based Multiple Audio Object Coding Approach Via Intra-Object Sparsity, Maoshen Jia, Jiaming Zhang, Changchun Bao, Xiguang Zheng
Faculty of Engineering and Information Sciences - Papers: Part B
Rendering spatial sound scenes via audio objects has become popular in recent years, since it can provide more flexibility for different auditory scenarios, such as 3D movies, spatial audio communication and virtual classrooms. To facilitate high-quality bitrate-efficient distribution for spatial audio objects, an encoding scheme based on intra-object sparsity (approximate k-sparsity of the audio object itself) is proposed in this paper. The statistical analysis is presented to validate the notion that the audio object has a stronger sparseness in the Modified Discrete Cosine Transform (MDCT) domain than in the Short Time Fourier Transform (STFT) domain. By exploiting intra-object sparsity in β¦
A Potential Field Approach-Based Trajectory Control For Autonomous Electric Vehicles With In-Wheel Motors, Boyuan Li, Haiping Du, Weihua Li
A Potential Field Approach-Based Trajectory Control For Autonomous Electric Vehicles With In-Wheel Motors, Boyuan Li, Haiping Du, Weihua Li
Faculty of Engineering and Information Sciences - Papers: Part B
The studies on the autonomous electric vehicle are quite attractive due to fewer human-induced errors and improved safety in recent years. Extensive research has been done on the autonomous steering control of the mobile robot, but study on the on-road autonomous electric vehicle is still limited. This paper proposes a potential field method to achieve the trajectory control of the autonomous electric vehicle with in-wheel motors. Instead of strictly following a desired path, this method can form a steering corridor with a desired tracking error tolerance and the vehicle can be steered smoothly with less control effort. In this paper, β¦

Effects Of Oil-In-Water Based Nanolubricant Containing Tio2 Nanoparticles In Hot Rolling Of 304 Stainless Steel, Wenzhen Xia, Jingwei Zhao, Hui Wu, Xianming Zhao, Xiaoming Zhang, Jianzhong Xu, Sihai Jiao, Zhengyi Jiang
Faculty of Engineering and Information Sciences - Papers: Part B
Energy saving and improvement of product quality are of crucial importance in hot rolling of 304 stainless steel. In this paper, oil-in-water (O/W) based nanolubricants containing TiO2 nanoparticles were developed to reduce the rolling force and improve the surface quality of rolled 304 stainless steel product. Practical hot rolling tests with and without application of lubricant were conducted to systematically investigate the effects of the developed O/W based nanolubricants on the rolling force, surface roughness, oxide scale thickness and tribological behaviour. The obtained results indicate that the nanoparticles can enter the deform zone with oil droplets to take a β¦

Estimating Cross-Classified Population Counts Of Multidimensional Tables: An Application To Regional Australia To Obtain Pseudo-Census Counts, Thomas F. Suesse, Mohammad-Reza Namazi-Rad, Payam Mokhtarian, Johan Barthelemy
Faculty of Engineering and Information Sciences - Papers: Part B
Estimating population counts for multidimensional tables based on a representative sample subject to known marginal population counts is not only important in survey sampling but is also an integral part of standard methods for simulating area-specific synthetic populations. In this article several estimation methods are reviewed, with particular focus on the iterative proportional fitting procedure and the maximum likelihood method. The performance of these methods is investigated in a simulation study for multidimensional tables, as previous studies are limited to 2 by 2 tables. The data are generated under random sampling but also under misspecification models, for which sample and β¦

Faculty of Engineering and Information Sciences - Papers: Part B
Background: The proportion of granule types in wheat starch is an important characteristic that can affect its functionality. It is widely accepted that granule types are either large, disc-shaped A-type granules or small, spherical B-type granules. Additionally, there are some reports of the tiny C-type granules. The differences between these granule types are due to its carbohydrate composition and crystallinity which is highly, but not perfectly, correlated with the granule size. A majority of the studies that have considered granule types analyse them based on a size threshold rather than chemical composition. This is understandable due to the expense of β¦

Faculty of Engineering and Information Sciences - Papers: Part B
Supplementary Instruction, also known as Peer Assisted Study Sessions (PASS), is a popular program supporting the educational development of students in a collaborative setting. Flexibility of delivery has been explored for a number of reasons including: work and family commitments; distance from campus; and integrating regional and transnational satellite campuses. Previous studies have found attempts to undertake online delivery of PASS lacking in student interest and have been restrained by the technology. This study attempts to build upon this research by investigating student interest and the suitability of using a mixed reality technology called iSee, based on video avatars within β¦

Faculty of Engineering and Information Sciences - Papers: Part B
This study aimed to identify risk factors in medication management in Australian residential aged care (RAC) homes. Only 18 out of 3,607 RAC homes failed aged care accreditation standard in medication management between 7th March 2011 and 25th March 2015. Text data mining methods were used to analyse the reasons for failure. This led to the identification of 21 risk indicators for an RAC home to fail in medication management. These indicators were further grouped into ten themes. They are overall medication management, medication assessment, ordering, dispensing, storage, stock and disposal, administration, incident report, monitoring, staff and resident satisfaction. The β¦

Covert Qr Codes: How To Hide In The Crowd, Yang-Wai Chow, Willy Susilo, Joon Sang Baek
Faculty of Engineering and Information Sciences - Papers: Part B
This paper investigates a novel approach of distributing a hidden message via public channels. The proposed approach employs visual subterfuge to conceal secret information within a QR code. Using a QR code reader, any individual can decode the public information contained in the QR code. However, only authorized users who have the necessary credentials will be able to obtain the secret message, which is encoded in the form of a secret QR code. We call this a Covert QR (CQR) code scheme. To embed the secret information, this approach exploits the error correction mechanism inherent in the QR code structure. β¦

Faculty of Engineering and Information Sciences - Papers: Part B
This study investigated the influence of inorganic salts on enzymatic activity and the removal of trace organic contaminants (TrOCs) by crude laccase from the white-rot fungus Pleurotus ostreatus. A systematic analysis of 15 cations and anions from common inorganic salts was presented. Laccase activity was not inhibited by monovalent cations (i.e. Na+ , NH4+ , K+ ), while the presence of divalent and trivalent cations showed variable impact - from negligible to complete inhibition - of both laccase activity and its TrOC removal performance. Of interest was the observation of discrepancy between residual laccase activity β¦

As part of Carbon Capture and Storage (CCS) projects, Carbon Dioxide (CO2) is usually transported via pipelines from source to sequestration location. Ensuring the safety of the operation is of great importance, as CO2 is a hazardous substance and an accidental release may have catastrophic consequences. Therefore, a comprehensive understanding of the effects of a CO2 release from CCS facilities is essential to allow the appropriate safety precautions to be taken. The majority of prior studies that address this topic do so by simulating CO2 dispersion over a flat horizontal terrain. However, CO2 pipelines β¦

The Tuned Absorptance In Multilayer Graphene-Dielectric Structures By Intraband Transition, C H. Yang, Guoxiu Wang, C Zhang, Zhimin Ao
Faculty of Engineering and Information Sciences - Papers: Part B
In this work, using the transfer-matrix method, the optical transport process is investigated, with graphene inserted into multilayer dielectric structures, theoretically and numerically in the THz regime. When the incident frequency is lower than the graphene Fermi energy, the optical intra-band transitions provide the main contribution to the graphene surface current. The absorptance can be enhanced to about 50% with only one graphene/dielectric layer in air. When increasing the number of dielectric layers coated with graphene, the absorption increases. Periodic absorption peaks are observed in multilayer structures. The positions of the absorption peaks as a function of the frequency and β¦

The use of simulation to predict building energy performance has been shown to have significant benefits in terms of reducing energy consumption and greenhouse gas emissions. However, in terms of implementation, the process can be disjointed and messy, with a lack of integration between architects and engineers. For the process of creating a building energy simulation to be more efficient, a seamless transition from an architectural design to an energy model is required. This paper highlights some of the practical issues manifest in the process of data exchange for energy analysis. It presents a proposed workflow for the exchange of β¦

Modelling And Control Of A Novel Walker Robot For Post-Stroke Gait Rehabilitation, Emre Sariyildiz, Hsiao-Ju Cheng, Gokhan M. Yagli, Haoyong Yu
Faculty of Engineering and Information Sciences - Papers: Part B
In this paper, a novel walker robot is proposed for post-stroke gait rehabilitation. It consists of an omni-directional mobile platform which provides high mobility in horizontal motion, a linear motor that moves in vertical direction to support the body weight of a patient and a 6-axis force/torque sensor to measure interaction force/torque between the robot and patient. The proposed novel walker robot improves the mobility of pelvis so it can provide more natural gait patterns in rehabilitation. This paper analytically derives the kinematic and dynamic models of the novel walker robot. Simulation results are given to validate the proposed kinematic β¦

Observer-Based Load Frequency Control For Island Microgrid With Photovoltaic Power, Chaoxu Mu, Weiqiang Liu, Wei Xu, Md Rabiul Islam
Faculty of Engineering and Information Sciences - Papers: Part B
As renewable energy is widely integrated into the power system, the stochastic and intermittent power generation from renewable energy may cause system frequency deviating from the prescribed level, especially for a microgrid. In this paper, the load frequency control (LFC) of an island microgrid with photovoltaic (PV) power and electric vehicles (EVs) is investigated, where the EVs can be treated as distributed energy storages. Considering the disturbances from load change and PV power, an observer-based integral sliding mode (OISM) controller is designed to regulate the frequency back to the prescribed value, where the neural network observer is used to online β¦

Rigidity And Stability Of Spheres In The Helfrich Model, Yann Bernard, Glen Wheeler, V.-M Wheeler
Faculty of Engineering and Information Sciences - Papers: Part B
The Helfrich functional, denoted by Hc0, is a mathematical expression proposed by Helfrich (1973) for the natural free energy carried by an elastic phospholipid bilayer. Helfrich theorises that idealised elastic phospholipid bilayers minimise Hc0 among all possible configurations. The functional integrates a spontaneous curvature parameter c0 together with the mean curvature of the bilayer and constraints on area and volume, either through an inclusion of osmotic pressure difference and tensile stress or otherwise. Using the mathematical concept of embedded orientable surface to represent the configuration of the bilayer, one might expect to be able to adapt methods from differential geometry β¦

Experimental And Numerical Investigations Into Hydraulic Behaviour Of Coir Fibre Drain, Thanh Trung Nguyen, Buddhima Indraratna
Faculty of Engineering and Information Sciences - Papers: Part B
Over many decades, natural fibre bundles have been widely used for drainage and filtration applications because of their favourable hydraulic conductivity and abundance in Asian countries. In recent times, natural (biodegradable) coir and jute drains, which are environmentally friendly, have been considered in lieu of conventional geosynthetic wick drains for soft clay consolidation in Australian coastal regions. However, there is a lack of a computational framework to predict the hydraulic behaviour of fibre drains on the basis of micromechanical (fabric) characteristics. Employing computational fluid dynamics (CFD) coupled with the discrete element method (DEM) to model the hydraulic behaviour of fibrous β¦

Faculty of Engineering and Information Sciences - Papers: Part B
In this study, the moment tensor of transversely isotropic shale was analyzed using a discrete element method-acoustic emission model (DEM-AE model). Firstly, the failure modes of the shale obtained from the acoustic emission (AE) events and physical experiments were compared. Secondly, the relationships between AE events and seismic magnitudes, and AE events and the resulting cracks were analyzed. Finally, a moment tensor T-k chart describing the seismic source was introduced to demonstrate the differences in the transversely isotropic shale. The results showed that, for different anisotropy angles, a linear logarithmic relationship existed between the cumulative AE events and the seismic β¦

A Study Of User Perception Of The Quality Of Video Content Rendered Inside A 3-D Virtual Environment, Pedram Pourashraf, Farzad Safaei, Daniel R. Franklin
Faculty of Engineering and Information Sciences - Papers: Part B
This paper reports on the result of a user study to assess the impact of resolution and frame rate of video on the quality of experience of the users, when the video is rendered inside a 3-D virtual space, and consequently viewed from arbitrary perspectives. A mathematical model for video rate is presented that expresses the total rate as the product of separate functions of spatial and temporal resolutions. Results from the user study are combined with the model to predict the rate parameters which will result in perceptually acceptable quality using the 3-D features of the virtual environment. The β¦
