Assessing The Influence Of Climatic Variables On Electricity Demand, Dao Hoang Vu, Kashem M. Muttaqi, Ashish P. Agalgaonkar
Assessing The Influence Of Climatic Variables On Electricity Demand, Dao Hoang Vu, Kashem M. Muttaqi, Ashish P. Agalgaonkar
Faculty of Engineering and Information Sciences - Papers: Part A
The electricity demand is significantly dependent on the weather information. Such weather information is comprised of different climatic variables such as temperature, humidity, wind speed, evaporation, rain fall and solar exposure which constantly change. Therefore, analysing the impacts of these variables on demand is necessary for predicting the future change in demand. In this paper, the cooling and heating degree days are utilised to capture the relationship between the per capita demand to temperature, which is one of the key climatic variables. In addition, Pearson correlation analysis has been employed to investigate the interdependency between different climatic variables and electricity …

Multi-Objective Ant Colony System For Data-Intensive Service Provision, Lijuan Wang, Jun Shen, Junzhou Luo
Faculty of Engineering and Information Sciences - Papers: Part A
Data-intensive services have become one of the most challenging applications in cloud computing. The classical service composition problem will face new challenges as the services and correspondent data grow. A typical environment is the large scale scientific project AMS, which we are processing huge amount of data streams. In this paper, we will resolve service composition problem by considering the multi-objective data-intensive features. We propose to apply ant colony optimization algorithms and implemented them with simulated workflows in different scenarios. To evaluate the proposed algorithm, we compared it with a multi-objective genetic algorithm with respect to five performance metrics

Influence Of Polarization And A Source Model For Dose Calculation In Mrt, Stefan Bartzsch, Michael Lerch, Marco Petasecca, Elke Brauer-Krisch, Uwe Oelfke
Faculty of Engineering and Information Sciences - Papers: Part A
Purpose: Microbeam Radiation Therapy (MRT), an alternative preclinical treatment strategy using spatially modulated synchrotron radiation on a micrometer scale, has the great potential to cure malignant tumors (e.g., brain tumors) while having low side effects on normal tissue. Dose measurement and calculation in MRT is challenging because of the spatial accuracy required and the arising high dose differences. Dose calculation with Monte Carlo simulations is time consuming and their accuracy is still a matter of debate. In particular, the influence of photon polarization has been discussed in the literature. Moreover, it is controversial whether a complete knowledge of phase space …
Mitigation Of Landslide Impacts, Strategies And Challenges For The 21st Century, Robin Chowdhury, Phil Flentje
Mitigation Of Landslide Impacts, Strategies And Challenges For The 21st Century, Robin Chowdhury, Phil Flentje
Faculty of Engineering and Information Sciences - Papers: Part A
Reliable methods for mitigation of landslide impacts must be based on the latest developments in knowledge and advanced methods of analysis and synthesis. An interdisciplinary approach is essential for effective solutions to landslide problems. Prevention or mitigation of landslide disasters requires understanding the factors which often lead to catastrophic landsliding and the simulation of conditions under which such failures may occur. The analysis of rainfall-triggered landsliding in saturated soils requires a proper understanding of how the factor of safety decreases with increase in pore water pressure. On the other hand, for landsliding in unsaturated soils it is necessary to understand …

Pycmsxio: An External Interface To Script Treatment Plans For The Elekta® Cms Xio Treatment Planning System, Aitang Xing, Sankar Arumugam, Lois Holloway, Gary Goozee
Faculty of Engineering and Information Sciences - Papers: Part A
Scripting in radiotherapy treatment planning systems not only simplifies routine planning tasks but can also be used for clinical research. Treatment planning scripting can only be utilized in a system that has a built-in scripting interface. Among the commercially available treatment planning systems, Pinnacle (Philips) and Raystation (Raysearch Lab.) have inherent scripting functionality. CMS XiO (Elekta) is a widely used treatment planning system in radiotherapy centres around the world, but it does not have an interface that allows the user to script radiotherapy plans. In this study an external scripting interface, PyCMSXiO, was developed for XiO using the Python programming …

Negative ion formation in collisions of potassium atoms with tetrahydrofuran (THF) and D-Ribose (DR) were performed in a crossed molecular beam setup equipped with a time- of-flight (TOF) mass spectrometer. Owing to the role of these molecules as possible representations of the sugar unit in the DNA/RNA, the fragmentation patterns obtained for different collision energies were compared and the role of K+ post-collision interaction with the molecular is evaluated.
In Situ Micro-Raman Studies Of Laser-Induced Bismuth Oxidation Reveals Metastability Of Beta-Bi2o3 Microislands, J A. Steele, R A. Lewis
In Situ Micro-Raman Studies Of Laser-Induced Bismuth Oxidation Reveals Metastability Of Beta-Bi2o3 Microislands, J A. Steele, R A. Lewis
Faculty of Engineering and Information Sciences - Papers: Part A
We report the laser irradiation-induced oxidation of bismuth metal investigated in situ by micro-Raman spectroscopy as a function of irradiation power and time. The purely optical synthesis and characterization of beta-Bi2O3 oxide microislands on metallic Bi surfaces is shown to be stable over time, even at room-temperature. By closely examining possible reactions on simple Bi morphologies it is revealed for the first time that the ensuing oxide phase is critically dependent on the final oxide volume and follows a fixed kinetic transformation sequence: 3/2 O2(g)+2Bi(l) -> beta-Bi2O3(s) -> alpha-Bi2O3(s). These findings are unusual within the framework of traditional Bi2O3 thermal …

A Structure Optimization Algorithm Of Neural Networks For Large-Scale Data Sets, Jie Yang, Jun Ma, Matthew J. Berryman, Pascal Perez
Faculty of Engineering and Information Sciences - Papers: Part A
Over the past several decades, neural networks have evolved into powerful computation systems, which are able to learn complex nonlinear input-output relationship from data. However, the structure optimization problem of neural network is a big challenge for processing huge-volumed, diversified and uncertain data. This paper focuses on this problem and introduces a network pruning algorithm based on sparse representation, termed SRP. The proposed approach starts with a large network, then selects important hidden neurons from the original structure using a forward selection criterion that minimizes the residual output error. Furthermore, the presented algorithm has no constraints on the network type. …

Stochastic Modeling And Optimization Of Multi-Plant Capacity Planning Problem, Anoop Verma, Nagesh Shukla, S.K Tyagi, Nishikant Mishra
Faculty of Engineering and Information Sciences - Papers: Part A
n this paper the problem of capacity planning under risk from demand and price/cost uncertainty of the finished products is addressed. The deterministic model is extended into a two-stage stochastic model with fixed recourse by means of various expected levels of demand as random. A recourse penalty is also included in the objective for both shortage and surplus in the finished products. The model is analyzed to quantify the risk using Markowitz mean-variance model.
Real-Time Task Attributes And Temporal Constraints, Amir Ashamalla, Ghassan Beydoun, N Paramesh
Real-Time Task Attributes And Temporal Constraints, Amir Ashamalla, Ghassan Beydoun, N Paramesh
Faculty of Engineering and Information Sciences - Papers: Part A
Real-time tasks need attributes for monitoring their execution and performing recovery actions in case of failures. Temporal constraints are a class of real-time task attributes where the constraints relate the status of the task to temporal entities. Violating temporal constraints can produce consequences of unknown severity. This paper is part of our on-going research on real-time multi agent systems constraints. We discuss the importance of temporal constraints and present a task model that explicitly represents temporal constraints. We also present our preliminary results from our initial implementation in the domain of Meeting Schedules Management involving multiple users assisted by agents.

Recent studies show that mental disorders change the functional organization of the brain, which could be investigated via various imaging techniques. Analyzing such changes is becoming critical as it could provide new biomarkers for diagnosing and monitoring the progression of the diseases. Functional connectivity analysis studies the covary activity of neuronal populations in different brain regions. The sparse inverse covariance estimation (SICE), also known as graphical LASSO, is one of the most important tools for functional connectivity analysis, which estimates the interregional partial correlations of the brain. Although being increasingly used for predicting mental disorders, SICE is basically a generative …

Electro-Tactile Feedback System For Achieving Embodiment In A Tele-Operated Robot, Daniel Pamungkas, Koren Ward
Faculty of Engineering and Information Sciences - Papers: Part A
Tele-operation can enable an operator to control a robot remotely in inaccessible and hazardous environments. However, controlling a robot remotely via a conventional monitor and control panel can be difficult and slow. To achieve faster and more dexterous operation of the robot, enhanced 3D perception and some form of tactile or neural feedback is needed to achieve some degree of embodiment within the robot's physical structure and world. To achieve this objective we have devised an immersive tele-operation system comprised of a stereo vision headset and an electro-tactile feedback system that is worn by the operator, connected to stereo cameras …

Estimating The Magnitude Of Method Bias On Account Of Text Similarity Using A Natural Language Processing-Based Technique, Rajeev Sharma, Murad Safadi, Megan Andrews, Philip O. Ogunbona, Jeff Crawford
Faculty of Engineering and Information Sciences - Papers: Part A
A number of potential biases have been identified that may contribute a spurious component to the observed correlation between variables. One such potential bias is the manner in which items are worded. This paper presents a technique and a program of research to estimate the magnitude of method bias arising from item wording. We hypothesize that the greater the level of text similarity between items employed to capture predictor and criterion variables, the greater the magnitude of the observed effect size between them. Two samples will be employed; one investigating the perceived usefulness-use correlations reported in the TAM literature and …

Task-Basedwireless Mobile Agents Search And Deployment For Ad Hoc Network Establishment In Disaster Environments, Xing Su, Minjie Zhang, Quan Bai
Faculty of Engineering and Information Sciences - Papers: Part A
In disaster environments, due to the destruction of local communication infrastructures, wireless mobile agents (robots) are employed to search and deploy to establish ad hoc networks. With the guidance of the network, first responders can efficiently perform tasks in disaster environments. However, due to the uncertainties and complexities of disaster environments and the limited capabilities of wirelessmobile agents, it is challenging to apply wireless mobile agents to disaster environments in both theory and practice. To this end, a task-based wireless mobile agents search and deployment approach is proposed for ad hoc network establishment in disaster environments. The proposed approach consists …

Multi-Phase Ant Colony System For Multi-Party Data-Intensive Service Provision, Lijuan Wang, Jun Shen
Faculty of Engineering and Information Sciences - Papers: Part A
The rapid proliferation of enormous sources of digital data has led to greater dependence on data-intensive services. Each service may actually request or create a large amount of data sets. To compose these services will be more challenging. Issues such as autonomy, scalability, adaptability, and robustness, become difficult to resolve. In order to automate the process of reaching an agreement among service composers, service providers, and data providers, an ant-inspired negotiation mechanism is considered in this paper. We exploit a group of agents automatically negotiating to establish agreeable service contracts. Twostage negotiation procedures are used in our data-intensive service provision …
Revisiting Optimistic Fair Exchange Based On Ring Signatures, Yang Wang, Man Ho Au, Willy Susilo
Revisiting Optimistic Fair Exchange Based On Ring Signatures, Yang Wang, Man Ho Au, Willy Susilo
Faculty of Engineering and Information Sciences - Papers: Part A
Optimistic fair exchange (OFE) is a kind of protocol that solves the fair exchange problem with the help of a trusted third party, usually referred to as an arbitrator. Participation of the arbitrator is required only when there is a dispute amongst the exchanging parties. Thus, the majority of the executions of the exchange does not involve the arbitrator and hence the term optimistic. The passive nature of the arbitrator makes optimistic fair exchange a desirable tool in applications such as contract signing and electronic commerce. The highest level of security of optimistic fair exchange in the literature is the …

K-Times Attribute-Based Anonymous Access Control For Cloud Computing, Joseph K. Liu, Tsz Hon Yuen, Man Ho Au, Xinyi Huang, Willy Susilo, Jianying Zhou
Faculty of Engineering and Information Sciences - Papers: Part A
In this paper, we propose a new notion called k-times attribute-based anonymous access control, which is particularly designed for supporting cloud computing environment. In this new notion, a user can authenticate himself/herself to the cloud computing server anonymously. The server only knows the user acquires some required attributes, yet it does not know the identity of this user. In addition, we provide a k-times limit for anonymous access control. That is, the server may limit a particular set of users (i.e., those users with the same set of attribute) to access the system for a maximum k-times within a period …

Enhanced Privacy Of A Remote Data Integrity-Checking Protocol For Secure Cloud Storage, Yong Yu, Man Ho Au, Yi Mu, S Tang, J Ren, Willy Susilo, Liju Dong
Enhanced Privacy Of A Remote Data Integrity-Checking Protocol For Secure Cloud Storage, Yong Yu, Man Ho Au, Yi Mu, S Tang, J Ren, Willy Susilo, Liju Dong
Faculty of Engineering and Information Sciences - Papers: Part A
Remote data integrity checking (RDIC) enables a server to prove to an auditor the integrity of a stored file. It is a useful technology for remote storage such as cloud storage. The auditor could be a party other than the data owner; hence, an RDIC proof is based usually on publicly available information. To capture the need of data privacy against an untrusted auditor, Hao et al. formally defined "privacy against third party verifiers" as one of the security requirements and proposed a protocol satisfying this definition. However, we observe that all existing protocols with public verifiability supporting data update, …

Contaminated soil and groundwater resulting from pyrite oxidation occur in coastal areas throughout the world, but do not pose an issue unless allowed to oxidise as a result of drainage or excavation. The exposure and oxidisation of these soils increase the concentration of iron and aluminium ions and cause adverse impact on flora and fauna and also water quality. Depending on the climate conditions and scale of areas contaminated by acid sulphate soil (ASS), several remediation techniques (e.g. fixed-level weirs, two-way modified floodgates, permeable reactive barriers, etc.) can be employed to increase the pH near to neutral and prevent the …

Faculty of Engineering and Information Sciences - Papers: Part A
In Australia, increasing demand for High Speed Rail (HSR) and heavier freight transport is a technical and economic challenge for practicing engineers, designers and researchers. Because of this increased train speed and axle load, high undue stresses are transferred to the ballast and underlying formation. Ballast degradation is a major factor affecting track longevity and stability. Use of energy absorbing shock mats to reduce noise and vibrations is an established practice. The shock mat is sometimes called as Under Sleeper Pad (USP) and Under Ballast Mat (UBM) depending upon their placement position. However, studies to analyse their effectiveness in minimising …
