Photonic-Based Multi-Wavelength Sensor For Object Identification, Kavitha Venkataraayan, Sreten Askraba, Kamal Alameh, John Rowe

Research outputs pre 2011

A Photonic-based multi-wavelength sensor capable of discriminating objects is proposed and demonstrated for intruder detection and identification. The sensor uses a laser combination module for input wavelength signal multiplexing and beam overlapping, a custom-made curved optical cavity for multi-beam spot generation through internal beam reflection and transmission and a high-speed imager for scattered reflectance spectral measurements. Experimental results show that five different wavelengths, namely 473nm, 532nm, 635nm, 670nm and 785nm, are necessary for discriminating various intruding objects of interest through spectral reflectance and slope measurements. Objects selected for experiments were brick, cement sheet, cotton, leather and roof tile.

Bots Trained To Play Like A Human Are More Fun, Bhuman Soni, Philip Hingston

Research outputs pre 2011

Computational intelligence methods are well-suited for use in computer controlled opponents for video games. In many other applications of these methods, the aim is to simulate near-optimal intelligent behaviour. But in video games, the aim is to provide interesting opponents for human players, not optimal ones. In this study, we trained neural network-based computer controlled opponents to play like a human in a popular first-person shooter. We then had gamers play-test these opponents as well as a hand-coded opponent, and surveyed them to find out which opponents they enjoyed more. Our results show that the neural network-based opponents were clearly …

Importance Of Verification And Validation Of Data Sources In Attaining Information Superiority, Gautham Kasinath, Leisa J. Armstrong

Research outputs pre 2011

Information superiority has been defined as a state that is achieved when a competitive advantage is derived from the ability to exploit a superior information position. To achieve such a superior information position enterprises and nations, alike, must not only collect and record correct, accurate, timely and useful information but also ensure that information recorded is not lost to competitors due to lack of comprehensive security and leaks. Further, enterprises that aim to attain information superiority must also ensure mechanisms of validating and verifying information to reduce the chances of mis-information. Although, research has been carried out into ways to …

Analysis Of Pki As A Means Of Securing Odf Documents, Gautham Kasinath, Leisa J. Armstrong

Research outputs pre 2011

Public Key Infrastructure (PKI) has for the last two decades been a means of securing systems and communication. With the adoption of Open Document Format (ODF) as an ISO standard, the question remains if the unpopular, expensive, complex and unmaintainable PKI can prove to be a viable means of securing ODF documents. This paper analyses the drawbacks of PKI and evaluates the useji.tlness of PKl in provisioning robust, cheap and maintainable XML security to XML based ODF. This paper also evaluates the existing research on XML security, more specifically fine grained access control.

Triangulation Based Static Wide Angle Laser Scanning For Obstacle Detection, Kaveh Sahba, Kamal Alameh, Clifton Smith

Research outputs pre 2011

This paper demonstrates discrete laser spot projection over a wide angle using a novel cylindrical quasi-cavity waveguide, with no moving parts. Furthermore, the distance to each spot is calculated using active laser triangulation. The triangulation arrangement and the trajectory of principal rays are modelled using a system of linear equations based on optical geometry. Linear algebra is used to derive the unique baseline and outgoing angle of every projected beam. The system is calibrated by finding optimal values for uncertain instrumental parameters using constrained non-linear optimization. Distances calculated indoors result in accuracies of over 93%

Research outputs pre 2011

Macroalgal epiphytes within seagrass meadows make a significant contribution to total primary production by assimilating water column N and transferring organic N to sediments. Assimilation of NO3 – requires nitrate reductase (NR, EC 1.6.6.1); NR activity represents the capacity for NO3 – assimilation. An optimised in vitro assay for determining NR activity in algal extracts was applied to a wide range of macroalgae and detected NR activity in all 22 species tested with activity 2 to 290 nmolNO3 – min–1 g–1 frozen thallus. With liquid-N2 freezing immediately after sample collection, this method was practical for estimating NR activity in field …

Blackhat Fingerprinting Of The Wired And Wireless Honeynet, Suen Yek

Research outputs pre 2011

TCP/IP fingerprinting is a common technique used to detect unique network stack characteristics of an Operating System (OS) . Its usage for network compromise is renowned for performing host discovery and in aiding the blackhat to determine a tailored exploit of detected OSs. The honeyd honeynet is able to countermeasure blackhats utilising TCP/IP fingerprinting via host device emulation on a virtual network. Honeyd allows the creation of host personalities that respond to network stack fingerprinting as a real network would. The nature of this technique however, has shown to provide inconsistent and unreliable results when performed over wired and wireless …

Algorithmic Composition In Contrasting Music Styles, Tristan Mcauley, Philip Hingston

Research outputs pre 2011

The aim of this research was to automate the composition of convincingly “real” music in specific musical genres. By “real” music we mean music which is not obviously “machine generated”, is recognizable as being of the selected genre, is perceived as aesthetically pleasing, and is usable in a commercial context. To achieve this goal, various computational techniques were used, including genetic algorithms and finite state automata. The process involves an original, top down approach and a bottom up approach based on previous studies. Student musicians have objectively assessed the resulting compositions.

Cutting Hacking: Breaking From Tradition, Rick Duley, Stanislaw P. Maj

Research outputs pre 2011

Code construction is the one inescapable phase of the software development cycle yet educators seem unable to escape the mind-set which equates programming with syntax and semantics. Accumulated coding wisdom of more than four decades, now being codified in the SWEBOK, should smooth the process of learning to develop software if presented early in the student's career. Typically, however, it continues to be presented in advanced programming units rather than as fundamental understanding. As a consequence, code hacking is the norm in undergraduate years. This paper examines current practice and presents the view that what is needed is not a …

The Mediated Integration Arcitecture For Heterogeneous Data Integration, Chaiyaporn Chirathamjaree, Suvimol Mukviboonchai

Research outputs pre 2011

To interoperate data sources which differ structurally and semantically, particular problems occur, for example, problems of changing schemas in data sources will affect the integrated schema. In this paper, we propose the mediated integration architecture (MedInt), which employs mediation and wrapping techniques as the main components for the integration of heterogeneous systems. With MedInt, a mediator acts as an intermediate medium transforming queries to sub-queries, integrating result data and resolving conflicts. Wrappers then transform sub-queries to specific local queries so that each local system is able to understand the queries.

B-Nodes: A New Scalable High Level Abstraction Model, Stanislaw P. Maj, Craig William Caulfield

Research outputs pre 2011

This paper proposes a new modeling technique called B-Nodes. B-Nodes represent a new, high-level abstraction that allows technical detail to be controlled using top-down recursive decomposition. This abstraction. is independent of architectural detail and can therefore accommodate rapid changes in technology. The use of recursive decomposition allows B-Nodes to be used not only for entire e-commerce system but also sub-modules within this system. The use of fundamental units allows the performance of heterogeneous technologies to be compared and other units to be derived. Results to date indicate no comparable model exists. Should further work validate this technique the authors recommend …
