Emerging Forms Of Covert Surveillance Using Gps-Enabled Devices, Roba Abbas, Katina Michael, M G. Michael, Anas Aloudat

Faculty of Informatics - Papers (Archive)

This paper presents the real possibility that commercial mobile tracking and monitoring solutions will become widely adopted for the practice of non-traditional covert surveillance within a community setting, resulting in community members engaging in the covert observation of family, friends, or acquaintances. This paper investigates five stakeholder relationships using scenarios to demonstrate the potential socio-ethical implications that tracking and monitoring people will have on society at large. The five stakeholder types explored in this paper include: (i) husband-wife (partner-partner), (ii) parent-child, (iii) employer-employee, (iv) friend-friend, and (v) stranger-stranger. Mobile technologies such as mobile camera phones, global positioning system data loggers, …

Generalised Morphisms Of K-Graphs: K-Morphs, Alex Kumjian, David Pask, Aidan Sims Jan 2011

Generalised Morphisms Of K-Graphs: K-Morphs, Alex Kumjian, David Pask, Aidan Sims

Faculty of Informatics - Papers (Archive)

In a number of recent papers, (k+l)-graphs have been constructed from k-graphs by inserting new edges in the last l dimensions. These constructions have been motivated by C*-algebraic considerations, so they have not been treated systematically at the level of higher-rank graphs themselves. Here we introduce k-morphs, which provide a systematic unifying framework for these various constructions. We think of k-morphs as the analogue, at the level of k-graphs, of C*-correspondences between C*-algebras. To make this analogy explicit, we introduce a category whose objects are k-graphs and whose …

Drug Diffusion From Polymeric Delivery Devices: A Problem With Two Moving Boundaries, Mike Hsieh, Scott Mccue, Timothy J. Moroney, Mark I. Nelson Jan 2011

Drug Diffusion From Polymeric Delivery Devices: A Problem With Two Moving Boundaries, Mike Hsieh, Scott Mccue, Timothy J. Moroney, Mark I. Nelson

Faculty of Informatics - Papers (Archive)

An existing model for solvent penetration and drug release from a spherically shaped polymeric drug delivery device is revisited. The model has two moving boundaries, one that describes the interface between the glassy and rubbery states of the polymer, and another that defines the interface between the polymer ball and the pool of solvent. The model is extended so that the nonlinear diffusion coefficient of drug explicitly depends on the concentration of solvent, and the resulting equations are solved numerically using a front fixing transformation together with a finite difference spatial discretisation and the method of lines. We present evidence …

An Analysis Of An Activated Sludge Process Containing A Sludge Disintegration System, Mark I. Nelson, Easwaran Balakrishnan Jan 2011

An Analysis Of An Activated Sludge Process Containing A Sludge Disintegration System, Mark I. Nelson, Easwaran Balakrishnan

Faculty of Informatics - Papers (Archive)

A continuous flow bioreactor is a well-stirred vessel containing microorganisms (X) through which a substrate (S) flows at a continuous rate. The microorganisms grow through the consumption of the substrate, producing more microorganisms and products. The products will typically contain carbon dioxide, nitrogen, water and other species, including biological compounds, specific to the process under consideration. The nature of these products is unimportant in this study. Unused substrate, microorganisms, and products flow out of the reactor. The use of a continuous flow bioreactor to treat sewage or industrial wastewaters is known as the activated sludge process. One drawback associated with …

Asymptotic And Numerical Results For A Model Of Solvent-Dependent Drug Diffusion Through Polymeric Spheres, Scott Mccue, Mike Hsieh, Timothy J. Moroney, Mark I. Nelson Jan 2011

Asymptotic And Numerical Results For A Model Of Solvent-Dependent Drug Diffusion Through Polymeric Spheres, Scott Mccue, Mike Hsieh, Timothy J. Moroney, Mark I. Nelson

Faculty of Informatics - Papers (Archive)

A model for drug diffusion from a spherical polymeric drug delivery device is considered. The model contains two key features. The first is that solvent diffuses into the polymer, which then transitions from a glassy to a rubbery state. The interface between the two states of polymer is modeled as a moving boundary, whose speed is governed by a kinetic law; the same moving boundary problem arises in the one-phase limit of a Stefan problem with kinetic undercooling. The second feature is that drug diffuses only through the rubbery region, with a nonlinear diffusion coefficient that depends on the concentration …

The mathematical foundation of many real-world problems can be quite deep. Such a situation arises in the study of the flow and deformation (rheology) of viscoelastic materials such as naturally occurring and synthetic polymers. In order to advance polymer science and the efficient manufacture of synthetic polymers, it is necessary to recover information about the molecular structure within such materials. For the recovery of such information about a specific polymer, it is necessary to determine its relaxation modulus G(t) and its creep modulus J(t). They correspond to the kernels of the Boltzmann causal integral equation models of stress relaxation and …

A Spatial Analysis Of Multivariate Output From Regional Climate Models, Stephan Sain, Reinhard Furrer, Noel A. Cressie Jan 2011

A Spatial Analysis Of Multivariate Output From Regional Climate Models, Stephan Sain, Reinhard Furrer, Noel A. Cressie

Faculty of Informatics - Papers (Archive)

Climate models have become an important tool in the study of climate and climate change, and ensemble experiments consisting of multiple climate-model runs are used in studying and quantifying the uncertainty in climate-model output. However, there are often only a limited number of model runs available for a particular experiment, and one of the statistical challenges is to characterize the distribution of the model output. To that end, we have developed a multivariate hierarchical approach, at the heart of which is a new representation of a multivariate Markov random field. This approach allows for flexible modeling of the multivariate spatial …

An Ontology-Mediated Validation Of Software Models, Antonio Lopez Lorca, Ghassan Beydoun, Leon Sterling, Tim Miller Jan 2011

An Ontology-Mediated Validation Of Software Models, Antonio Lopez Lorca, Ghassan Beydoun, Leon Sterling, Tim Miller

Faculty of Informatics - Papers (Archive)

When errors in software modelling activities propagate to later phases of software development lifecycle, they become costlier to fix and lower the qual-ity of the final product. Early validation of software models can prevent rework and incorrect development non-compliant with client’s specification. In this paper we advocate the use of ontologies to validate and improve the quality of software models as they are being developed, at the same time bridging the traditional gap between developers and clients. We propose a general ontology-mediated process to validate software models that can be adapted in a broad range of software de-velopment projects. We …

P2cp: A New Cloud Storage Model To Enhance Performance Of Cloud Services, Zhe Sun, Jun Shen, Ghassan Beydoun Jan 2011

P2cp: A New Cloud Storage Model To Enhance Performance Of Cloud Services, Zhe Sun, Jun Shen, Ghassan Beydoun

Faculty of Informatics - Papers (Archive)

This paper presents a storage model named Peer to Cloud and Peer (P2CP). Assuming that the P2CP model follows the Poisson process or Little’s law, we prove that the speed and availability of P2CP is generally better than that of the pure Peer to Peer (P2P) model, the Peer to Server, Peer (P2SP) model or the cloud model. A key feature of our P2CP is that it has three data transmission tunnels: the cloud-user data transmission tunnel, the clients’ data transmission tunnel, and the common data transmission tunnel. P2CP uses the cloud storage system as a common storage system. When …

Using Ontologies To Synchronize Change In Relational Database Systems, Waqas Ahmed, Muhammad Ahtisham Aslam, Antonio Lopez Lorca, Jun Shen, Ghassan Beydoun, Debbie Richards Jan 2011

Using Ontologies To Synchronize Change In Relational Database Systems, Waqas Ahmed, Muhammad Ahtisham Aslam, Antonio Lopez Lorca, Jun Shen, Ghassan Beydoun, Debbie Richards

Faculty of Informatics - Papers (Archive)

Ontology is a building block of the semantic Web. Ontology building requires a detailed domain analysis, which in turn requires financial resources, intensive domain knowledge and time. Domain models in industry are frequently stored as relational database schemas in relational databases. An ontology base underlying such schemas can represent concepts and relationships that are present in the domain of discourse. However, with ever increasing demand for wider access and domain coverage, public databases are not static and their schemas evolve over time. Ontologies generated according to these databases have to change to reflect the new situation. Once a database schema …

Measuring The Feedback Parameter Of A Semiconductor Laser With External Optical Feedback, Yanguang Yu, Jiangtao Xi, Joe F. Chicharo Jan 2011

Measuring The Feedback Parameter Of A Semiconductor Laser With External Optical Feedback, Yanguang Yu, Jiangtao Xi, Joe F. Chicharo

Faculty of Informatics - Papers (Archive)

Feedback parameter (the C factor) is an important parameter for a semiconductor laser operating in the regime of external optical feedback. Self-mixing interferometry (SMI) has been proposed for the measurement of the parameter, based on the time-domain analysis of the output power waveforms (called SMI signals) in presence of feedback. However, the existing approaches only work for a limited range of C, below about 3.5. This paper presents a new method to measure C based on analysis of the phase signal of SMI signals in the frequency domain. The proposed method covers a large range of C values, up to …

Recovering The Absolute Phase Maps Of Two Fringe Patterns With Selected Frequencies, Yi Ding, Jiangtao Xi, Yanguang Yu, Joe F. Chicharo Jan 2011

Recovering The Absolute Phase Maps Of Two Fringe Patterns With Selected Frequencies, Yi Ding, Jiangtao Xi, Yanguang Yu, Joe F. Chicharo

Faculty of Informatics - Papers (Archive)

Phase unwrapping is an important and challenging issue in fringe pattern profilometry. In this Letter we propose an approach to recover absolute phase maps of two fringe patterns with selected frequencies. Compared to existing temporal multiple frequency algorithms, the two frequencies in our proposed algorithm can be high enough and thus enable efficient and accurate recovery of absolute phase maps. Experiment results are presented to confirm the effectiveness of the proposed technique.

A Voxel-Based Octree Construction Approach For Procedural Cave Generation, Juncheng Cui, Yang-Wai Chow, Minjie Zhang Jan 2011

A Voxel-Based Octree Construction Approach For Procedural Cave Generation, Juncheng Cui, Yang-Wai Chow, Minjie Zhang

Faculty of Informatics - Papers (Archive)

Procedural content generation is becoming an increasingly popular research area as a means of algorithmically generating scene content for virtual environments. The automated generation of such content avoids the manual labour typically associated with creating scene content, and is extremely useful in application areas such as computer graphics, movie production and video games. While virtual 3D caves are commonly featured in these virtual environment applications, procedural cave generation is not an area that has received much attention among researchers to date. This paper presents a procedural approach to generating 3D cave structures. Other than the development of a method to …

A Low Complexity Resource Allocation Algorithm For Ofdma Cooperative Relay Networks With Fairness And Qos Guaranteed, Asem Salah, R. S.A.R. Abdullah, B. B. M. Ali, Nidhal Odeh Jan 2011

A Low Complexity Resource Allocation Algorithm For Ofdma Cooperative Relay Networks With Fairness And Qos Guaranteed, Asem Salah, R. S.A.R. Abdullah, B. B. M. Ali, Nidhal Odeh

Faculty of Informatics - Papers (Archive)

This paper proposes a new resource allocation algorithm for uplink OFDMA-based cooperative relay networks, assuming multiple user nodes, multiple relay nodes and a single destination. The aim is to maximise the total sum of the users' data rates, while guaranteeing fairness among them with different QoS requirements. Assuming perfect channel state information (CSI) at the resource allocation controller, the optimisation problem is formulated such that each user is assigned a weight factor based on its QoS requirements. The ones with higher weights are given higher priorities to select their resources (relay stations and subcarriers) first. Once the required QoS is …

Analysis Of First-Year Student Performance In An Engineering Program, Philip Ciufo Jan 2011

Analysis Of First-Year Student Performance In An Engineering Program, Philip Ciufo

Faculty of Informatics - Papers (Archive)

During the last ten years, the typical criteria for entry to an engineering course at a university in NSW, Australia, has been based on the University Admission Index (UAI). It was an index derived largely from the achievements of a student in examinations at the end of their secondary school education. The UAI provided a measure of overall academic achievement that assisted institutions to rank applicants for tertiary selection. In 2010, the UAI in NSW was replaced by the Australian Tertiary Admission Rank (ATAR). A student who is able to rank well enough, will be able to enter an engineering …

Why Students Leave Their Ict Degrees: A Gender Comparison, Madeleine Rh Roberts, Tanya Mcgill, Peter N. Hyland

Faculty of Informatics - Papers (Archive)

Student attrition is of particular concern in the field of ICT because the industry faces staffing shortfalls, generally and a noticeable lack of female employees. This paper explores the reasons students give for leaving their ICT courses and examines gender differences in them. An online survey of early leavers from four Australian universities was conducted. The results show that, for many students, a combination of issues lead to their withdrawal. Whilst the gender imbalance was certainly noted, sexist behaviour from male staff or students was not rated highly as an issue in terms of the withdrawal of female students from …

Conditional And Unconditional Models In Model-Assisted Estimation Of Finite Population Totals, David G. Steel, Robert Graham Clark Jan 2011

Conditional And Unconditional Models In Model-Assisted Estimation Of Finite Population Totals, David G. Steel, Robert Graham Clark

Faculty of Informatics - Papers (Archive)

The well known Godambe-Joshi lower bound for the anticipated variance of design unbiased estimators of population totals treats the auxiliary variables as constants. We extend the result to models where these variables are random and show that the generalized difference estimator using the expected values conditional on all auxiliary values is optimal. This has several implications including the fact that collecting multiple survey variables does not reduce the lower bound.

Reorientational Versus Kerr Dark And Gray Solitary Waves Using Modulation Theory, Gaetano Assanto, Timothy R. Marchant, Antonmaria Minzoni, Noel Smyth Jan 2011

Reorientational Versus Kerr Dark And Gray Solitary Waves Using Modulation Theory, Gaetano Assanto, Timothy R. Marchant, Antonmaria Minzoni, Noel Smyth

Faculty of Informatics - Papers (Archive)

We develop a modulation theory model based on a Lagrangian formulation to investigate the evolution of dark and gray optical spatial solitary waves for both the defocusing nonlinear Schr¨odinger (NLS) equation and the nematicon equations describing nonlinear beams, nematicons, in self-defocusing nematic liquid crystals. Since it has an exact soliton solution, the defocusing NLS equation is used as a test bed for the modulation theory applied to the nematicon equations,which have no exact solitarywave solution.We find that the evolution of dark and gray NLS solitons, as well as nematicons, is entirely driven by the emission of diffractive radiation, in contrast …

Exploring The Role Of Ict In The Formation Of Transactive Memory Systems In Virtual Teams, Mohamed Imran Ariff, Simon K. Milton, Rachelle Bosua, Rajeev Sharma Jan 2011

Exploring The Role Of Ict In The Formation Of Transactive Memory Systems In Virtual Teams, Mohamed Imran Ariff, Simon K. Milton, Rachelle Bosua, Rajeev Sharma

Faculty of Informatics - Papers (Archive)

This paper is a research in progress. Virtual teams (VTs) are increasingly common in organizations, yet explicit research on VTs’ performance is relatively rare. One of the key challenges faced by individuals in VTs is the awareness of ‘who knows what’ and ‘who does what’ in the team. One of the solutions offered by past research in overcoming these key challenges is for teams to form Transactive Memory Systems (TMS). However, previous research on TMS has been limited and focused primarily on face-to-face teams yielding inconsistent results with respect to TMS formation in VTs. Therefore, the goal of this research …

Creating Value From Business Analytics Systems: The Impact Of Strategy, Graeme Shanks, Rajeev Sharma Jan 2011

Creating Value From Business Analytics Systems: The Impact Of Strategy, Graeme Shanks, Rajeev Sharma

Faculty of Informatics - Papers (Archive)

Business analytics systems can potentially contribute to firm performance and create competitive advantage. However, these benefits do not always follow from investment in business analytics technology. This paper argues that dynamic capabilities, enabled by business analytics technology, lead to value-creating actions and ultimately to improved firm performance. We develop a theoretical model that explains how organizational strategy relates to both business analytics technology and organizational structure, and impacts value-creating actions. We use the theoretical model to explain the implementation of a CRM system for one type of strategy.

Fpga Based Filter Design For Self-Mixing Interferometry Signals, Yuan Sun, Yanguang Yu, Wenbing Fan, Jiangtao Xi

Faculty of Informatics - Papers (Archive)

Self-mixing interferometry (SMI) signals are observed from a sensing system consisting of a laser diode with external optical feedbacks. SMI signals carry the information associated to both of the displacement and parameters of the SL. To retrieve the information precisely, pre-processing of SMI signals is the first key step. For achieving real-time, and high quality sensing, this paper proposes a Field-programmable gate arrays (FPGA) based filtering and normalizing processing for SMI signals. According to the noise features contained in SMI signal, a median filter and a wavelet transform based filter are combined for our design. Hardware co-simulation verified that the …

Concepts And Collections: A Case Study Using Objects From The Brooklyn Museum, Timothy Wray, Peter Eklund

Faculty of Informatics - Papers (Archive)

In this paper, we present a browsing framework for digitised cultural collections. Using a data analysis technique called Formal Concept Analysis (FCA), units of thought can be constructed from a series of objects and their tags. FCA can dynamically generate links in between objects and induce a serendipitous browsing experience using a relatively simple data structure. We evaluate the utility and scalability of our approach to a collection of 15,000 objects from the Brooklyn Museum’s collections. We describe how we use natural language processing techniques and external lexical resources to synthesise key terms from museum documentation. We then combine this …
