Key Characteristics-Based Sensor Distribution In Multi-Station Assembly Processes, Nagesh Shukla, Darek Ceglarek, Manoj K. Tiwari
Key Characteristics-Based Sensor Distribution In Multi-Station Assembly Processes, Nagesh Shukla, Darek Ceglarek, Manoj K. Tiwari
Nagesh Shukla
This paper presents a novel approach for optimal key characteristics-based sensor distribution in a multi-station assembly process, for the purpose of diagnosing variation sources responsible for product quality defects in a timely manner. Current approaches for sensor distribution are based on the assumption that measurement points can be allocated at arbitrary locations on the part or subassembly. This not only presents challenges in the implementation of these approaches but additionally does not allow required product assurance and quality control standards to be integrated with them, due to lack of explicit relations between measured features and geometric dimensioning and tolerancing (GD&T). …

The vehicle routing problem with stochastic demand (VRPSD) is a well known NP-hard problem. The uncharacteristic behaviour associated with the problem enhances the computational efforts required to obtain a feasible and near-optimal solution. This paper proposes an algorithm portfolio methodology based on evolutionary algorithms, which takes into account the stochastic nature of customer demand to solve this computationally complex problem. These problems are well known to have computationally complex objective functions, which make their solutions hard to find, particularly when problem instances of large dimensions are considered. Of particular importance in such situations is the timeliness of the solution. For …

Identity-Based Data Storage In Cloud Computing, Jinguang Han, Willy Susilo, Yi Mu
Professor Willy Susilo
Identity-based proxy re-encryption schemes have been proposed to shift the burden of managing numerous files from the owner to a proxy server. Nevertheless, the existing solutions suffer from several drawbacks. First, the access permission is determined by the central authority, which makes the scheme impractical. Second, they are insecure against collusion attacks. Finally, only queries from the same domain (intra-domain) are considered. We note that one of the main applications of identity-based proxy re-encryption schemes is in the cloud computing scenario. Nevertheless, in this scenario, users in different domains can share files with each other. Therefore, the existing solutions do …
A Secure And Effective Anonymous User Authentication Scheme For Roaming Service In Global Mobility Networks, Fentong Wen, Willy Susilo, Guomin Yang
A Secure And Effective Anonymous User Authentication Scheme For Roaming Service In Global Mobility Networks, Fentong Wen, Willy Susilo, Guomin Yang
Professor Willy Susilo
In global mobility networks, anonymous user authentication is an essential task for enabling roaming service. In a recent paper, Jiang et al. proposed a smart card based anonymous user authentication scheme for roaming service in global mobility networks. This scheme can protect user privacy and is believed to have many abilities to resist a range of network attacks, even if the secret information stored in the smart card is compromised. In this paper, we analyze the security of Jiang et al.'s scheme, and show that the scheme is in fact insecure against the stolen-verifier attack and replay attack. Then, we …
Efficient Linkable And/Or Threshold Ring Signature Without Random Oracles, Tsz Hon Yuen, Joseph K. Liu, Man Ho Au, Willy Susilo, Jianying Zhou
Efficient Linkable And/Or Threshold Ring Signature Without Random Oracles, Tsz Hon Yuen, Joseph K. Liu, Man Ho Au, Willy Susilo, Jianying Zhou
Professor Willy Susilo
Linkable ring signatures have found many attractive applications. One of the recent important extensions is a linkable threshold ring signature (LTRS) scheme. Unfortunately, the existing LTRS schemes are only secure in the random oracle model (ROM). In this paper, we make the following contributions. First, we construct the first LTRS scheme that is secure without requiring the ROM. Further, we enhance the security of a threshold ring signature (for both linkable or non-linkable) by providing a stronger definition of anonymity. This strengthened notion makes threshold ring signature schemes more suitable in real life. Finally, we provide efficient schemes that outperform …

Social Implications Of Technology: The Past, The Present, And The Future, Karl Stephan, Katina Michael, M. G. Michael, Laura Jacob, Emily Anesta
Professor Katina Michael
The social implications of a wide variety of technologies are the subject matter of the IEEE Society on Social Implications of Technology (SSIT). This paper reviews the SSIT’s contributions since the Society’s founding in 1982, and surveys the outlook for certain key technologies that may have significant social impacts in the future. Military and security technologies, always of significant interest to SSIT, may become more autonomous with less human intervention, and this may have both good and bad consequences. We examine some current trends such as mobile, wearable, and pervasive computing, and find both dangers and opportunities in these trends. …

Gestural Interface Technology In Early Childhood Education: A Framework For Fully Engaged Communication, Holly Tootell, Melinda Plumb, Colin D. Hadfield, Linda Dawson
Associate Professor Linda Dawson
Gestural Interface Technology (GIT) has changed the way technology is adopted in classrooms for all ages. The accessibility of control through touch means that technology such as Apple's iPad can be used in early childhood education. In this paper, we introduce a framework for fully-engaged communication, developed from educational pedagogy and critical engagement in information systems. The intersection of these dimensions creates a view of a GIT lifeworld approach which allows it to be used to understand multiple layers of engagement that exist within an early childhood education environment.

Order-4 Quasi-Orthogonal Cooperative Communication In Stfc Mb-Ofdm Uwb, Zixuan Lin, Le Chung Tran, Farzad Safaei, Tadeusz A. Wysocki
Professor Farzad Safaei
Recently, cooperative communication and Space-Time-Frequency-Codes (STFCs) have been introduced into the Multiband OFDM Ultra-Wideband (MB-OFDM UWB) to improve the reliability, data rate and system capacity. This paper proposes a cooperative communication scheme for a four source node MB-OFDM UWB system using Quasi-Orthogonal STFCs, which is referred to as order-4 Quasi-Orthogonal Cooperative Communication Scheme (4-QOCCS). Simulation results show that the proposed 4-QOCCS provides significantly better error performance over the conventional MB-OFDM UWB and our order-2 Orthogonal Cooperative Communication Scheme (2-OCCS) using the Alamouti STFCs, and even better than the order-4 Orthogonal Cooperative Communication Scheme (4-OCCS), which we have been recently proposed, …

Evidence-Free Policy: The Case Of The National Injury Insurance Scheme, Mark Harrison
Evidence-Free Policy: The Case Of The National Injury Insurance Scheme, Mark Harrison
Faculty of Engineering and Information Sciences - Papers: Part A
The Productivity Commission report 'Disability Care and Support' recommends tort liability be replaced by a compulsory, government-run, no-fault scheme. But theory and evidence indicate moving to a no-fault scheme will increase the accident rate. Even a move from non-risk-rated third-party insurance to non-risk-rated first-party insurance reduces incentives for care. A no-fault scheme is not superior to current policies; genuine reform will need to be informed by law and economics literature.
The Role Of Public Procurement In Improving Accessibility To Ict, Gunela Astbrink, William Tibben
The Role Of Public Procurement In Improving Accessibility To Ict, Gunela Astbrink, William Tibben
Faculty of Engineering and Information Sciences - Papers: Part A
Government bodies use public procurement policies and mechanisms to purchase ICT products and services. Some governments in OECD countries apply accessibility criteria when procuring ICT to improve access to their services and employment opportunities for people with disabilities. This may have a flow-on effect of greater availability of affordable and accessible ICT thus improving digital inclusion. This paper outlines research on comparative analysis of the situation in Australia with current policy in OECD countries. The research resulted in recommendations for a consumer-oriented plan to work with Australian governments on the introduction of accessibility criteria in ICT public procurement.
Security Analysis Of A Distributed Reprogramming Protocol For Wireless Sensor Networks, Yong Yu, Jianbing Ni, Ying Sun
Security Analysis Of A Distributed Reprogramming Protocol For Wireless Sensor Networks, Yong Yu, Jianbing Ni, Ying Sun
Faculty of Engineering and Information Sciences - Papers: Part A
Reprogramming for wireless sensor networks is essential to upload new code or to alter the functionality of existing code. To overcome the weakness of the centralized approach of the traditional solutions, He et al. proposed the notion of distributed reprogramming where multiple authorized network users are able to reprogram sensor nodes without involving the base station. They also gave a novel distributed reprogramming protocol called SDRP by using identity-based signature, and provided a comprehensive security analysis for their protocol. In this letter, unfortunately, we demonstrate that SDRP is insecure as the protocol fails to satisfy the property of authenticity and …

Noise Robust Keyword Spotting For User Generated Video Blogs, M S. Barakat, C H. Ritz, D A. Stirling
Faculty of Engineering and Information Sciences - Papers: Part A
This paper presents a template-based system for speaker independent key word spotting (KWS) in continuous speech that can help in automatic analysis, indexing, search and retrieval of user generated videos by content. Extensive experiments on clean speech confirm that the proposed approach is superior to a HMM approach when applied to noisy speech with different signal-to-noise ratio (SNR) levels. Experiments conducted to detect swear words, personal names and product names within a set of online user generated video blogs shows significantly better recall and precision results compared to a traditional ASR-based approach.

The Joint Effect Of Image Blur And Illumination Distortions For Mobile Visual Search Of Print Media, Yi Cao, Christian Ritz, Raad Raad
Faculty of Engineering and Information Sciences - Papers: Part A
Mobile Visual Search (MVS) is an emerging area of research given the explosion of smart and powerful mobile devices. Typically, the performance of MVS applications is influenced by the implemented image processing algorithms as well as various distortions that occur when capturing images by the mobile camera. This paper examines the joint effect of two common distortions, namely the illumination changes and image blurring on image matching accuracy for print media when using four state-of-the art local feature algorithms. Results obtained for a database of real camera images captured by two different camera models show that the illumination changes have …
Approximation Algorithms For Interference Aware Broadcast In Wireless Networks, Dianbo Zhao, Kwan-Wu Chin
Approximation Algorithms For Interference Aware Broadcast In Wireless Networks, Dianbo Zhao, Kwan-Wu Chin
Faculty of Engineering and Information Sciences - Papers: Part A
Broadcast is a fundamental operation in wireless networks and is well supported by the wireless channel. However, the interference resulting from a node's transmission pose a key challenge to the design of any broadcast algorithms/protocols. In particular, it is well known that a node's interference range is much larger than its transmission range and thus limits the number of transmitting and receiving nodes, which inevitably prolong broadcast. To this end, a number of past studies have designed broadcast algorithms that account for this interference range with the goal of deriving a broadcast schedule that minimizes latency. However, these works have …

To ensure confidentiality, the sensitive data are usually encrypted prior to being outsourced. Nevertheless, effective data utilization remains a challenging task and there is a clear need for a secure and efficient searching mechanism over the encrypted data in the cloud, to increase the us-ability of the secure cloud environment. Unfortunately, existing work in the area of …
Probabilistic Fuzzy Image Fusion Approach For Radar Through Wall Sensing, C H. Seng, A Bouzerdoum, M G. Amin, S L Phung
Probabilistic Fuzzy Image Fusion Approach For Radar Through Wall Sensing, C H. Seng, A Bouzerdoum, M G. Amin, S L Phung
Faculty of Engineering and Information Sciences - Papers: Part A
This paper addresses the problem of combining multiple radar images of the same scene to produce a more informative composite image. The proposed approach for probabilistic fuzzy logic-based image fusion automatically forms fuzzy membership functions using the Gaussian-Rayleigh mixture distribution. It fuses the input pixel values directly without requiring fuzzification and defuzzification, thereby removing the subjective nature of the existing fuzzy logic methods. In this paper, the proposed approach is applied to through-the-wall radar imaging in urban sensing and evaluated on real multiview and polarimetric data. Experimental results show that the proposed approach yields improved image contrast and enhances target …

Risk Management In Liner Ship Fleet Deployment: A Joint Chance Constrained Programming Model, Tingsong Wang, Qiang Meng, Shuaian Wang, Zhijia Tan
Faculty of Engineering and Information Sciences - Papers: Part A
This paper provides a tangible methodology to deal with the liner ship fleet deployment problem aiming at minimizing the total cost while maintaining a service level under uncertain container demand. The problem is first formulated as a joint chance constrained programming model, and the sample average approximation method and mixed-integer programming are used to deal with it. Finally, a numerical example of a liner shipping network is carried out to verify the applicability of the proposed model and solution algorithm. It is found that the service level has significant effect on the total cost.

Strong Amicable Orthogonal Designs And Amicable Hadamard Matrices, Jennifer Seberry
Strong Amicable Orthogonal Designs And Amicable Hadamard Matrices, Jennifer Seberry
Faculty of Engineering and Information Sciences - Papers: Part A
Amicable orthogonal designs have renewed interest because of their use in mobile communications. We show the existence of strong amicable orthogonal designs, AOD(n: 1, n - 1; 1, n - 1), for n = pr + 1, p ≡ 3 (mod 4) a prime and for n = 2r, n a non-negative integer in a form more suitable for communications. Unfortunately the existence of amicable Hadamard matrices is not enough to demonstrate the existence of strong amicable orthogonal designs.

Performance Evaluation Of Cooperative Communications For Stfc Mb-Ofdm Uwb, Zixuan Lin, Le Chung Tran, Farzad Safaei
Faculty of Engineering and Information Sciences - Papers: Part A
Recently, the combination of cooperative communication, Space-Time-Frequency Codes (STFCs) and Multiband OFDM Ultra-Wideband (MB-OFDM UWB) has been proposed to improve the data rate, system capacity and reliability. This paper provides insightful performance evaluation for our previous proposed cooperative communication schemes for MBOFDM UWB systems. In particular, this paper shows that the usefulness of cooperative communication schemes is decided by the mutual relation between the signal-to-noise ratio (SNR) of the inter-node links, referred to as inter-node SNR, and that of the uplinks, which is referred to as uplink SNR. For a certain uplink SNR value, cooperative communication becomes useful when the …
Realizing Fully Secure Unrestricted Id-Based Ring Signature In The Standard Model Based On Hibe, Man Ho Au, Joseph K. Liu, Willy Susilo, Jianying Zhou
Realizing Fully Secure Unrestricted Id-Based Ring Signature In The Standard Model Based On Hibe, Man Ho Au, Joseph K. Liu, Willy Susilo, Jianying Zhou
Faculty of Engineering and Information Sciences - Papers: Part A
We describe a secure and unrestricted identity-based ring signature scheme in the standard model. Our construction is provably fully secure in the standard model under static assumptions and is motivated by an existing HIBE scheme. Our observation on the relationship between ID-based ring signatures and HIBE is of interest to researchers in other fields as well. Following the strongest anonymity definition in ring signatures, we define a new level of anonymity for ID-based ring signatures in which the attacker can specify the randomness used in the creation of the user secret key, in addition to the private key generators master …
Systematic Network Design For Liner Shipping Services, Shuaian Wang, Zhiyuan Liu, Qiang Meng
Systematic Network Design For Liner Shipping Services, Shuaian Wang, Zhiyuan Liu, Qiang Meng
Faculty of Engineering and Information Sciences - Papers: Part A
A systematic design for a liner shipping network was addressed. Many practical features in real-world operations, including multiple types of containers, container transshipment operations, empty container repositioning, origin-to-destination transit time constraints, consistent services with the current network, and joint services with other liner shipping companies, were considered. Given a set of candidate ship routes, some of these routes had to be used, and the use of others was optional. A mixed-integer linear programming model was proposed for the selection of optional ship routes. The solution of this model provided the laden and empty container flow on the selected ship routes. …
