A BIASED COMPETITION COMPUTATIONAL MODEL OF SPATIAL AND OBJECT-BASED ATTENTION MEDIATING ACTIVE VISUAL SEARCH
Creators: name: LANYON, LINDA JANE
Publisher: name: University of Plymouth
Year: 2005

description: A computational cognitive neuroscience approach was used to examine processes of visual attention in the human and monkey brain. The aim of the work was to produce a biologically plausible neurodynamical model of both spatial and object-based attention that accounted for observations in monkey visual areas V4, inferior temporal cortex (IT) and the lateral intraparietal area (LIP), and was able to produce search scan path behaviour similar to that observed in humans and monkeys. Of particular interest currently in the visual attention literature is the biased competition hypothesis (Desimone & Duncan. 1995). The model presented here is the first active vision implementation of biased competition, where attcntional shifts are overt. Therefore, retinal inputs change during the scan path and this approach raised issues, such as memory for searched locations across saccades, not addressed bv previous models with static retinas. This is the first model to examine the different time courses associated with spatial and object-based effects at the cellular level. Single cell recordings in areas V4 (Luck et al., 1997; Chelazzi et al., 2001) and IT (Chelazzi ct al., 1993, 1998) were replicated such that attentional effects occurred at the appropriate time after onset of the stimulus. Object-based effects at the cellular level of the model led to systems level behaviour that replicated that observed during active visual search for orientation and colour feature conjunction targets in psychophysical investigations. This provides a valuable insight into the link between cellular and system level behaviour in natural systems. At the systems level, the simulated search process showed selectivity in its scan path that was similar to that observed in humans (Scialfa & Joffe, 1998; Williams & Reingold, 2001) and monkeys (Motter & Belky. 1998b), being guided to target coloured locations in preference to locations containing the target orientation or blank areas. A connection between the ventral and dorsal visual processing streams (Ungerleider & Mishkin. 1982) is suggested to contribute to this selectivity and priority in the featural guidance of search. Such selectivity and avoidance of blank areas has potential application in computer vision applications. Simulation of lesions within the model and comparison with patient data provided further verification of the model. Simulation of visual neglect due to parietal cortical lesion suggests that the model has the capability to provide insights into the neural correlates of the conscious perception of stimuli The biased competition approach described here provides an extendable framework within which further "bottom-up" stimulus and "top-down" mnemonic and cognitive biases can be added, in order to further examine exogenous versus endogenous factors in the capture of attention.

The Use of Concept Questions to Improve Student Understanding of Mechanics, and the Formulation of a Hierarchical Model of Student Understanding of Moments of Forces
Creators: name: ROWLANDS, STUART KENNETH
Publisher: name: University of Plymouth
Year: 1997

description: The aims and objectives of the first part of the thesis are to create and evaluate a teaching package that would enable the teacher to facilitate student conceptual understanding of mechanics. The second part is to create a hierarchical model of student conceptual understanding of moments of forces. The thesis reports on the various conflicting theories and recommended teaching strategies from the research into student misconceptions, and examines the various underlying philosophical trends (for example, radical and social constructivism, the Vygotskian perspective and positivism) that have influenced the research into misconceptions in mechanics. As a result, the philosophical perspective of the thesis is that the analysis of the structure of Newtonian mechanics ought to be before the consideration of challenging misconceptions. The question as to how students can construct for themselves the Newtonian system ought to be prior to the consideration of designing a strategy to tackle misconceptions. With prior consideration of the structure of mechanics, the thesis examines the formation of the intuitive schema of force and motion. The thesis proposes the Socratic method of strategic questioning as the most appropriate teaching method for constructing the Newtonian system and displacing the intuitive schema of force and motion. The thesis reports on the formation, and the evaluation, of the teaching package as an aid to facilitate the construction of the Newtonian system, and concludes that teachers have to be trained in the use of the Socratic method prior to any evaluation. There has been little or no research in the area of misconceptions concerning moments. The thesis reports on the formation of a hierarchical model of understanding moments. From a sample of 417 students nation-wide, the thesis has identified 3 conceptual levels of understanding moments and discusses the teaching implications based on the responses from the sample.

Mathematical Analysis of Novel Magnetic Recording Heads
Creators: name: Shute, Hazel Anne
Publisher: name: University of Plymouth
Year: 1995

description: As a contribution to increasing the areal density of digital data stored on a magnetic recording medium, this thesis provides mathematical analyses of various magnetic recording heads. Each of the heads considered here is for use in a perpendicular recording system, writing to or reading from a multi-layer medium which includes a high magnetic permeability layer between the data storage layer and the substrate. The exact two-dimensional analysis is performed in each case by one of two methods: either Fourier analysis or conformal mapping. The types of heads analysed include conventional styles but particular emphasis is placed on the effects of the novel idea of potential grading across the pole pieces. Exact head fields are derived for thin film heads with both constant and linearly varying pole potentials, single pole heads with linearly and arbitrarily varying pole potentials and shielded magnetoresistive heads, all in the presence of a magnetic underlayer. These and other published solutions are used to derive output characteristics for perpendicular replay heads, which are compared with published theoretical and experimental results where possible. The Fourier solutions obtained are in the form of infinite series dependent on at least one set of coefficients which are determined by infinite systems of linear equations. Approximations to the potentials in the head face planes, independent of these coefficients, are derived from the exact Fourier solutions. The accuracy of these approximations is demonstrated when they are used to estimate the vertical field components and the spectral response functions. Heads with graded pole potentials are found to have more localised vertical field components than the corresponding constant potential heads. They are also better suited for use with thin media for 'in contact' recording.

Dynamical Systems Theory for Transparent Symbolic Computation in Neuronal Networks

Subjects: subject: Automata Theory, Recurrent Neural Networks, Representation Theory, Neural Symbolic Computation, Dynamical Systems, Symbolic Dynamics
subject: PhD

description: In this thesis, we explore the interface between symbolic and dynamical system computation, with particular regard to dynamical system models of neuronal networks. In doing so, we adhere to a definition of computation as the physical realization of a formal system, where we say that a dynamical system performs a computation if a correspondence can be found between its dynamics on a vectorial space and the formal system’s dynamics on a symbolic space. Guided by this definition, we characterize computation in a range of neuronal network models. We first present a constructive mapping between a range of formal systems and Recurrent Neural Networks (RNNs), through the introduction of a Versatile Shift and a modular network architecture supporting its real-time simulation. We then move on to more detailed models of neural dynamics, characterizing the computation performed by networks of delay-pulse-coupled oscillators supporting the emergence of heteroclinic dynamics. We show that a correspondence can be found between these networks and Finite-State Transducers, and use the derived abstraction to investigate how noise affects computation in this class of systems, unveiling a surprising facilitatory effect on information transmission. Finally, we present a new dynamical framework for computation in neuronal networks based on the slow-fast dynamics paradigm, and discuss the consequences of our results for future work, specifically for what concerns the fields of interactive computation and Artificial Intelligence.

USER-CENTRED METHODS IN THE ANALYSIS AND DESIGN OF SOFTWARE TOOLS TO SUPPORT MANAGEMENT CONSULTANTS
Creators: name: DIXON, MARK
Publisher: name: University of Plymouth
Year: 2000

description: The aim of the present work was to investigate the development of improved software tools for management consultants, and to investigate the effectiveness of augmented user-centred methods in this development, and thereby consider the more general use of augmented user-centred methods to develop software tools that support creative human activity systems. The research method used draws from and integrates aspects of user-centred design, soft systems methods, structured systems analysis and design, and software engineering. This includes using user literature, 'thinking aloud' role play observations, and interviews to develop a user model of the management consultancy process; using literature of related disciplines (qualitative data analysis and social network analysis), literature of existing computer assisted management consultant software tools, and formative iterative prototyping, empirical user testing and heuristic evaluation to synthesise a general design rationale of software tools for management consultants; and using empirical user testing and a subjective user acceptability interview to holistically evaluate the impact of the use of such software tools on the management consultancy process. The results provide evidence that the use of such software tools will provide significant benefits to management consultants, and that the overall impact can be summarised by delayed payback: although the use of the software draws out the early stages of an assignment it speeds up later stages, and although it may take a couple of assignments to realise its ftill potential, it leads to a deeper and more rigorous understanding of the client organisation. This leads to an original contribution to knowledge in the conclusions that integrated qualitative data analysis and social network analysis software tools can be useful to management consultants, and user-centred methods are important in the development of software tools for creative human activity systems.

ANALYSIS OF ITERATIVE METHODS FOR THE SOLUTION OF BOUNDARY INTEGRAL EQUATIONS WITH APPLICATIONS TO THE HELMHOLTZ PROBLEM
Creators: name: Ke, Chen
Publisher: name: University of Plymouth
Year: 1989

description: This thesis is concerned with the numerical solution of boundary integral equations and the numerical analysis of iterative methods. In the first part, we assume the boundary to be smooth in order to work with compact operators; while in the second part we investigate the problem arising from allowing piecewise smooth boundaries. Although in principle most results of the thesis apply to general problems of reformulating boundary value problems as boundary integral equations and their subsequent numerical solutions, we consider the Helmholtz equation arising from acoustic problems as the main model problem. In Chapter 1, we present the background material of reformulation of Helmhoitz boundary value problems into boundary integral equations by either the indirect potential method or the direct method using integral formulae. The problem of ensuring unique solutions of integral equations for exterior problems is specifically discussed. In Chapter 2, we discuss the useful numerical techniques for solving second kind integral equations. In particular, we highlight the superconvergence properties of iterated projection methods and the important procedure of Nystrom interpolation. In Chapter 3, the multigrid type methods as applied to smooth boundary integral equations are studied. Using the residual correction principle, we are able to propose some robust iterative variants modifying the existing methods to seek efficient solutions. In Chapter 4, we concentrate on the conjugate gradient method and establish its fast convergence as applied to the linear systems arising from general boundary element equations. For boundary integral equalisations on smooth boundaries we have observed, as the underlying mesh sizes decrease, faster convergence of multigrid type methods and fixed step convergence of the conjugate gradient method. In the case of non-smooth integral boundaries, we first derive the singular forms of the solution of boundary integral solutions for Dirichlet problems and then discuss the numerical solution in Chapter 5. Iterative methods such as two grid methods and the conjugate gradient method are successfully implemented in Chapter 6 to solve the non-smooth integral equations. The study of two grid methods in a general setting and also much of the results on the conjugate gradient method are new. Chapters 3, 4 and 5 are partially based on publications [4], [5] and [35] respectively.

ON TURBO CODES AND OTHER CONCATENATED SCHEMES IN COMMUNICATION SYSTEMS
Creators: name: AMBROZE, MARCEL ADRIAN
Publisher: name: University of Plymouth
Year: 2000

description: The advent of turbo codes in 1993 represented a significant step towards realising the ultimate capacity limit of a communication channel, breaking the link that was binding very good performance with exponential decoder complexity. Turbo codes are parallel concatenated convolutional codes, decoded with a suboptimal iterative algorithm. The complexity of the iterative algorithm increases only linearly with block length, bringing previously unprecedented performance within practical limits.. This work is a further investigation of turbo codes and other concatenated schemes such as the multiple parallel concatenation and the serial concatenation. The analysis of these schemes has two important aspects, their performance under optimal decoding and the convergence of their iterative, suboptimal decoding algorithm. The connection between iterative decoding performance and the optimal decoding performance is analysed with the help of computer simulation by studying the iterative decoding error events. Methods for good performance interleaver design and code design are presented and analysed in the same way. The optimal decoding performance is further investigated by using a novel method to determine the weight spectra of turbo codes by using the turbo code tree representation, and the results are compared with the results of the iterative decoder. The method can also be used for the analysis of multiple parallel concatenated codes, but is impractical for the serial concatenated codes. Non-optimal, non-iterative decoding algorithms are presented and compared with the iterative algorithm. The convergence of the iterative algorithm is investigated by using the Cauchy criterion. Some insight into the performance of the concatenated schemes under iterative decoding is found by separating error events into convergent and non-convergent components. The sensitivity of convergence to the Eb/Ng operating point has been explored.
A generic approach, employing information systems, for introducing manufacturing information systems in SME 's
Creators: name: Qurashi, Zahoor Ahmed
Publisher: name: University of Plymouth
Year: 2000

description: This thesis presents an approach which the small and medium size firms can use in-house to introduce manufacturing information systems. The approach developed is generic and employs information system design and analysis techniques to guide Small and Medium size Enterprises (SME's) from specification of their need, right through to the implementation of an appropriate solution. Although there are various tools and methodologies that are available for large organisations needs, none are available for SME's. Therefore, the approach presented in this thesis provides original and significant improvements on current practice. The approach emphasises the importance of taking a company wide approach to analyse systems throughout its various departments to establish bad practices and system flaws which may impinge on the performance of the manufacturing operations. The research involved three independent stages. The first stage was the identification of the problem which was realised from two sources: literature survey and interviews with case study company managers. The second stage was the development of a novel approach. The final stage included the validation of the approach by implementing it in five different SMEs in the Devon and Cornwall region. Through the use of this work, company's are encouraged to improve ownership and commitment to the manufacturing information systems by fully involving the relevant company personnel in identifying and resolving various problems. The approach proposed also helps managers understand how the various processes work in other areas of company, and can subsequently lead to improvements in other departments.
LINKING PERFORMANCE REQUIREMENTS WITH PROCESS IMPROVEMENT ACTIONS FOR BUSINESS PROCESS RE-DESIGN

Year: 2002

description: This thesis presents research that extends current knowledge in the area of business process re-design, with a specific focus on the 'Make Product' process within manufacturing organisations. Current business process re-design approaches offer only limited guidance on the specific changes that can be made to a process when re-designing it to achieve the desired performance improvements and often overlook any strategically derived performance requirements when re-designing the process. Case experience suggests that practitioners do not consider the performance requirements of their business processes when re-designing them and that the actions they take to achieve performance improvements are not selected with regard to any strategically derived performance requirements. This exploratory research investigates whether relationships can be established between the changes that can be made to a process when re-designing it and the performance improvements gained by implementing those changes. It then questions whether those relationships can be used to help companies to select the appropriate process changes to implement in order to meet their specific performance requirements. Performance Requirements and process changes (Process Improvement Actions) were derived from the relevant literature and included in a questionnaire designed to ascertain the strength of relationships between them. The questionnaire was subject to preliminary and pilot testing to improve validation and reliability prior to being administered to international business process re-design 'experts'. Statistical analysis of the questionnaire data resulted in a ranked list of Process Improvement Actions for each of the Performance Requirements. These were presented in a format for inclusion in a process-based change handbook and enable the practitioner to set the agenda for the intervention and select the Process Improvement Actions on the basis of the Performance Requirements. The Performance Requirements should be derived from the strategy of the company or change programme so a strategic focus is maintained throughout re-design. It was also found that of the thirteen Process Improvement Actions included in the questionnaire just five are needed to achieve improvements in a majority (80%) of the performance requirements. This research showed that it is possible to establish links between Performance Requirements and Process Improvement Actions and according to successful validation by practitioners, against an accepted model, that these can be used for business process re-design, laying foundations for future research in the area.

FLUID INERTIA AND END EFFECTS IN RHEOMETER FLOWS
Creators: name: HUGHES, JASON PETER
Publisher: name: University of Plymouth
Year: 1998

description: This thesis is concerned with the characterisation of the flow behaviour of inelastic and viscoelastic fluids in steady shear and oscillatory shear flows on commercially available rheometers. The first part of this thesis is concerned with a linear viscoelastic theory to describe the oscillatory shear flow behaviour of fluids on a Weissenberg rheogoniometer. A fluid inertia perturbation analysis is used to produce analytical formulae for correcting complex viscosity data for first and second order fluid inertia effects. In order to validate the perturbation theory we perform a simulation of the oscillatory shear flow behaviour of Newtonian and single element Maxwell fluids on a Weissenberg rheogoniometer. A theoretical prediction of end effects and fluid inertia effects on steady shear viscosity measurements of Newtonian fluids in a recessed concentric cylinder geometry is developed for a GSR controlled stress rheometer and a Weissenberg rheogoniometer. The relevant equations are solved using a perturbation analysis which is valid for low Reynolds number flows. From this theory correction formulae are produced to compensate for end effects and second order fluid inertia effects in steady shear flows on these instruments. End effects and fluid inertia effects are also investigated for power law shear thinning fluids. The final part of the thesis is concerned with a theoretical prediction of the end effect of a recessed concentric cylinder geometry on complex viscosity measurements of a generalised linear viscoelastic fluid. The linear viscoelastic theory is carried out for oscillatory shear flows on a CSR controlled stress rheometer and a Weissenberg rheogoniometer. A fluid inertia perturbation analysis is used to produce analytical formulae to correct complex viscosity data for end effects and second order fluid inertia effects. Numerically simulated oscillatory shear data is used to establish the limitations of the second order fluid inertia correction formulae which include end effects.
Active security vulnerability notification and resolution

description: The early version of the Internet was designed for connectivity only, without the consideration of security, and the Internet is consequently an open structure. Networked systems are vulnerable for a number of reasons; design error, implementation, and management. A vulnerability is a hole or weak point that can be exploited to compromise the security of the system. Operating systems and applications are often vulnerable because of design errors. Software vendors release patches for discovered vulnerabilities, and rely upon system administrators to accept and install patches on their systems. Many system administrators fail to install patches on time, and consequently leave their systems vulnerable to exploitation by hackers. This exploitation can result in various security breaches, including website defacement, denial of service, or malware attacks. The overall problem is significant with an average of 115 vulnerabilities per week being documented during 2005. This thesis considers the problem of vulnerabilities in IT networked systems, and maps the vulnerability types into a technical taxonomy. The thesis presents a thorough analysis of the existing methods of vulnerability management which determine that these methods have failed to mange the problem in a comprehensive way, and show the need for a comprehensive management system, capable of addressing the awareness and patch deploymentp roblems. A critical examination of vulnerability databasess tatistics over the past few years is provided, together with a benchmarking of the problem in a reference environment with a discussion of why a new approach is needed. The research examined and compared different vulnerability advisories, and proposed a generic vulnerability format towards automating the notification process. The thesis identifies the standard process of addressing vulnerabilities and the over reliance upon the manual method. An automated management system must take into account new vulnerabilities and patch deploymentt o provide a comprehensives olution. The overall aim of the research has therefore been to design a new framework to address these flaws in the networked systems harmonised with the standard system administrator process. The approach, known as AVMS (Automated Vulnerability Management System), is capable of filtering and prioritising the relevant messages, and then downloading the associated patches and deploying them to the required machines. The framework is validated through a proof-of-concept prototype system. A series of tests involving different advisories are used to illustrate how AVMS would behave. This helped to prove that the automated vulnerability management system prototype is indeed viable, and that the research has provided a suitable contribution to knowledge in this important domain.

INTELLIGENT VISION-BASED NAVIGATION SYSTEM
Creators: name: KOAY, KHENG LEE
Publisher: name: University of Plymouth
Year: 2003

description: This thesis presents a complete vision-based navigation system that can plan and follow an obstacle-avoiding path to a desired destination on the basis of an internal map updated with information gathered from its visual sensor. For vision-based self-localization, the system uses new floor-edges-specific filters for detecting floor edges and their pose, a new algorithm for determining the orientation of the robot, and a new procedure for selecting the initial positions in the self-localization procedure. Self-localization is based on matching visually detected features with those stored in a prior map. For planning, the system demonstrates for the first time a real-world application of the neural-resistive grid method to robot navigation. The neural-resistive grid is modified with a new connectivity scheme that allows the representation of the collision-free space of a robot with finite dimensions via divergent connections between the spatial memory layer and the neuro-resistive grid layer. A new control system is proposed. It uses a Smith Predictor architecture that has been modified for navigation applications and for intermittent delayed feedback typical of artificial vision. A receding horizon control strategy is implemented using Normalised Radial Basis Function nets as path encoders, to ensure continuous motion during the delay between measurements. The system is tested in a simplified environment where an obstacle placed anywhere is detected visually and is integrated in the path planning process. The results show the validity of the control concept and the crucial importance of a robust vision-based self-localization process.

Exploring and Exploiting Models of the Fitness Landscape: a Case Against Evolutionary Optimization
Creators: name: Moore, Jonathan Paul
Publisher: name: University of Plymouth
Year: 2000

description: In recent years, the theories of natural selection and biological evolution have proved popular metaphors for understanding and solving optimization problems in engineering design. This thesis identifies some fundamental problems associated with this use of such metaphors. Key objections are the failure of evolutionary optimization techniques to represent explicitly the goal of the optimization process, and poor use of knowledge developed during the process. It is also suggested that convergent behaviour of an optimization algorithm is an undesirable quality if the algorithm is to be applied to multimodal problems. An alternative approach to optimization is suggested, based on the explicit use of knowledge and/or assumptions about the nature of the optimization problem to construct Bayesian probabilistic models of the surface being optimized and the goal of the optimization. Distinct exploratory and exploitative strategies are identified for carrying out optimization based on such models—exploration based on attempting to reduce maximally an entropy-based measure of the total uncertainty concerning the satisfaction of the optimization goal over the space, exploitation based on evalutation of the point judged most likely to achieve the goal—together with a composite strategy which combines exploration and exploitation in a principled manner. The behaviour of these strategies is empirically investigated on a number of test problems. Results suggest that the approach taken may well provide effective optimization in a way which addresses the criticisms made of the evolutionary metaphor, subject to issues of the computational cost of the approach being satisfactorily addressed.
