Experimental Investigation Of Circular High-Strength Concrete Columns Reinforced With Glass Fiber-Reinforced Polymer Bars And Helices Under Different Loading Conditions, Muhammad N. S Hadi, Hayder Alaa Hasan, M Neaz Sheikh

Faculty of Engineering and Information Sciences - Papers: Part B

Existing design codes and guidelines do not adequately address the design of concrete columns reinforced with fiber-reinforced polymer (FRP) bars. Accordingly, a number of research studies investigated the behavior of FRP bar-reinforced concrete columns. However, the previous studies were limited to FRP bar-reinforced normal-strength concrete (NSC) columns. In this study, the behavior of glass fiber-reinforced polymer (GFRP) bar-reinforced high-strength concrete (HSC) specimens under different loading conditions was investigated in terms of axial load-carrying capacity, confinement efficiency of the GFRP helices, as well as the ductility and post-peak axial load-axial deformation response. The effects of the key parameters such as the …

Accurate Range Estimation For An Electric Vehicle Including Changing Environmental Conditions And Traction System Efficiency, Kaveh Sarrafan, Danny Sutanto, Kashem M. Muttaqi, Graham Town Jan 2017

Accurate Range Estimation For An Electric Vehicle Including Changing Environmental Conditions And Traction System Efficiency, Kaveh Sarrafan, Danny Sutanto, Kashem M. Muttaqi, Graham Town

Faculty of Engineering and Information Sciences - Papers: Part B

Range anxiety is an obstacle to the acceptance of electric vehicles (EVs), caused by drivers' uncertainty regarding their vehicle's state of charge (SoC) and the energy required to reach their destination. Most estimation methods for these variables use simplified models with many assumptions that can result in significant error, particularly if dynamic and environmental conditions are not considered. For example, the combined efficiency of the inverter drive and electric motor varies throughout the route and is not constant as assumed in most range estimation methods. This study proposes an improved method for SoC and range estimation by taking into account …

A Framework For Geotechnical Hazard Analysis In Highwall Mining Entries, Marc Elmouttie, Shivakumar Karekal Jan 2017

A Framework For Geotechnical Hazard Analysis In Highwall Mining Entries, Marc Elmouttie, Shivakumar Karekal

Faculty of Engineering and Information Sciences - Papers: Part B

Highwall mining involves driving a series of parallel entries with web pillars in between. These entries are driven by using a continuous miner with attached conveying system to extract locked up coal behind the highwall slope when the open cut coal mine reaches its ultimate limit. These entries are driven unmanned, unventilated and unsupported. Therefore, a detailed knowledge of structural features ahead of operations is essential in assessing the stability of these entries. Highwall mining operations can greatly benefit from accurate structural mapping of rock mass defects. The stability of these entries can be suitably assessed for any major roof …

Faculty of Engineering and Information Sciences - Papers: Part B

White-rot fungi (WRF) and their ligninolytic enzymes have been investigated for the removal of a broad spectrum of trace organic contaminants (TrOCs) mostly from synthetic wastewater in lab-scale experiments. Only a few studies have reported the efficiency of such systems for the removal of TrOCs from real wastewater. Wastewater derived organic and inorganic compounds can inhibit: (i) WRF growth and their enzyme production capacity; (ii) enzymatic activity of ligninolytic enzymes; and (iii) catalytic efficiency of both WRF and enzymes. It is observed that essential metals such as Cu, Mn and Co at trace concertation (up to 1 mM) can improve …

Constraining The Mass Balance Of East Antarctica, Alba Martin-Espanol, Jonathan Bamber, Andrew Zammit-Mangion

Faculty of Engineering and Information Sciences - Papers: Part B

We investigate the mass balance of East Antarctica for the period 2003-2013 using a Bayesian statistical framework. We combine satellite altimetry, gravimetry, and GPS with prior assumptions characterizing the underlying geophysical processes. We run three experiments based on two different assumptions to study possible solutions to the mass balance. We solve for trends in surface mass balance, ice dynamics, and glacial isostatic adjustment. The first assumption assigns low probability to ice dynamic mass loss in regions of slow flow, giving a mean dynamic trend of 17 ± 10 Gt yr-1 and a total mass imbalance of 57 ± 20 Gt …

Trucks Are Destroying Our Roads And Not Picking Up The Repair Cost, Philip G. Laird Jan 2017

Trucks Are Destroying Our Roads And Not Picking Up The Repair Cost, Philip G. Laird

Faculty of Engineering and Information Sciences - Papers: Part B

It's high time Australia changed its current road user charges for trucks. The shortfall between the charges for heavy vehicles and the money spent on things like road system maintenance, construction costs, road crashes involving heavy trucks, emissions, pollution and urban road congestion amounts to a taxpayer subsidy for the industry of at least A$3 billion per annum. The current charges, like those of cars, rely only on annual registration fees and fuel taxation. Instead Australia should be following the lead of New Zealand, Switzerland and some other European countries and introducing a charge system based on mass and distance. …

On The Energy Efficiency Of Adaptive Wban Systems For Mhealth Services, Miftadi Sudjai, Le Chung Tran, Farzad Safaei

Faculty of Engineering and Information Sciences - Papers: Part B

We recently proposed an adaptive Wireless Body Area Network (WBAN) system for mHealth service, which shows better bit error performance compared to the non-adaptive one. However, analysis and maximization of the energy efficiency as one of the key design considerations of these networks remain an open problem. Therefore, this paper investigates the energy efficiency of the proposed adaptive WBAN system by considering both the transmission power and the power consumed in the circuitry which consists of rate-independent and rate-dependent components. Since the distance between the hub and the wireless access point in WBAN is relatively short, beside the transmission power, …

Metamorphic Testing For Adobe Data Analytics Software, Darryl C. Jarman, Zhiquan Zhou, Tsong Yueh Chen

Faculty of Engineering and Information Sciences - Papers: Part B

It is challenging to test data analytics software because a test oracle might not be available. This study reports our experience of applying metamorphic testing to Adobe's data analytics software that is used for anomaly detection in a set of time series data. We make use of geometric transformations to build metamorphic relations and generate simple time series data as the source test cases. The results of this study show that metamorphic testing is highly effective for both verification and validation purposes. An investigation of the issues detected during metamorphic testing revealed three bugs in the software under test.

Hierarchical Functional Encryption For Linear Transformations, Shiwei Zhang, Yi Mu, Guomin Yang, Xiaofen Wang Jan 2017

Hierarchical Functional Encryption For Linear Transformations, Shiwei Zhang, Yi Mu, Guomin Yang, Xiaofen Wang

Faculty of Engineering and Information Sciences - Papers: Part B

In contrast to the conventional all-or-nothing encryption, functional encryption (FE) allows partial revelation of encrypted information based on the keys associated with different functionalities. Extending FE with key delegation ability, hierarchical functional encryption (HFE) enables a secret key holder to delegate a portion of its decryption ability to others and the delegation can be done hierarchically. All HFE schemes in the literature are for general functionalities and not very practical. In this paper, we focus on the functionality of linear transformations (i.e. matrix product evaluation). We refine the definition of HFE and further extend the delegation to accept multiple keys. …

Mergeable And Revocable Identity-Based Encryption, Shengmin Xu, Guomin Yang, Yi Mu, Willy Susilo Jan 2017

Mergeable And Revocable Identity-Based Encryption, Shengmin Xu, Guomin Yang, Yi Mu, Willy Susilo

Faculty of Engineering and Information Sciences - Papers: Part B

Identity-based encryption (IBE) has been extensively studied and widely used in various applications since Boneh and Franklin proposed the first practical scheme based on pairing. In that seminal work, it has also been pointed out that providing an efficient revocation mechanism for IBE is essential. Hence, revocable identity-based encryption (RIBE) has been proposed in the literature to offer an efficient revocation mechanism. In contrast to revocation, another issue that will also occur in practice is to combine two or multiple IBE systems into one system, e.g., due to the merge of the departments or companies. However, this issue has not …

Privacy-Preserving K-Time Authenticated Secret Handshakes, Yangguang Tian, Shiwei Zhang, Guomin Yang, Yi Mu, Yong Yu Jan 2017

Privacy-Preserving K-Time Authenticated Secret Handshakes, Yangguang Tian, Shiwei Zhang, Guomin Yang, Yi Mu, Yong Yu

Faculty of Engineering and Information Sciences - Papers: Part B

Secret handshake allows a group of authorized users to establish a shared secret key and at the same time authenticate each other anonymously. A straightforward approach to design an unlinkable secret handshake protocol is to use either long-term certificate or one-time certificate provided by a trusted authority. However, how to detect the misusing of certificates by an insider adversary is a challenging security issue when using those approaches for unlinkable secret handshake. In this paper, we propose a novel k-time authenticated secret handshake (k-ASH) protocol where each authorized user is only allowed to use the credential for k times. We …

Analysis Of Hydrodynamic Mechanism On Particles Focusing In Micro-Channel Flows, Qikun Wang, Dan Yuan, Weihua Li Jan 2017

Analysis Of Hydrodynamic Mechanism On Particles Focusing In Micro-Channel Flows, Qikun Wang, Dan Yuan, Weihua Li

Faculty of Engineering and Information Sciences - Papers: Part B

In this paper, the hydrodynamic mechanism of moving particles in laminar micro-channel flows was numerically investigated. A hydrodynamic criterion was proposed to determine whether particles in channel flows can form a focusing pattern or not. A simple formula was derived to demonstrate how the focusing position varies with Reynolds number and particle size. Based on this proposed criterion, a possible hydrodynamic mechanism was discussed as to why the particles would not be focused if their sizes were too small or the channel Reynolds number was too low. The Re-¿ curve (Re, ¿ respectively represents the channel-based Reynolds number and the …
