  • Self localisation in indoor environments using machine vision 

    Khan, Nabeel Younus
    The performance of outdoor positioning has become excellent with the emergence of Global Positioning System (GPS), but GPS is not reliable indoors. The ability of a system to perform indoor positioning without GPS is still ...
  • Semi-automated assessment of SQL schemas via database unit testing 

    Stanger, Nigel
    A key skill for students learning relational database concepts is how to design and implement a database schema in SQL. This skill is often tested in an assignment where students derive a schema from a natural language ...
  • Some neuro-computational investigations into the reviewing of object-files 

    Liddle, Michael David
    When a person attends to an object, a temporary working memory representation is created for it, specific to that individual “token” object. This differs from more general accumulated memories for “types” of objects. Kahneman, ...
  • Spatial data acquisition from motion video 

    Williams, Mark
    Geographic information systems are an important tool for the field of geocomputing. A key component of every system is the data—spatial data has traditionally been labour-intensive to collect, and hence expensive. This ...
  • Special issue: GeoComputation ’96 

    Anderson, Martin; Kasabov, Nikola; Purvis, Martin; Benwell, George; Kennedy, Geoff; Sallis, Philip
    A collection of papers authored by members of the Information Science department and presented at the 1st International Conference on GeoComputation, Leeds, United Kingdom. (The individual papers are also available separately.)
  • Spinal Cord Axon Segmentation 

    MacDonell, Benjamin Lachlan
    An automatic method for accurately segmenting MRI images of axons would reduce the manpower required for axon and myelin research. We implement active contours, which is reported to successfully identify axons in electron ...
  • SQUALID: A deductive DBMS 

    Stanger, Nigel
    Most modern companies probably could not function without a database management system (DBMS). Although current DBMSs are becoming increasingly sophisticated, they are still deficient in several areas. One of these areas ...
  • Task Scheduling in Data Stream Processing Systems 

    Eskandari, Leila
    In the era of big data, with streaming applications such as social media, surveillance monitoring and real-time search generating large volumes of data, efficient Data Stream Processing Systems (DSPSs) have become essential. ...
  • Techniques for utterance disambiguation in a human-computer dialogue system 

    Lurcock, Pontus Conrad
    Disambiguating an utterance occurring in a dialogue context is a complex task, which requires input from many different sources of information -- some syntactic, some semantic, and some pragmatic. The central question ...
  • The Boltzmann Machine: a Connectionist Model for Supra-Classical Logic 

    Blanchette, Glenn Clifford
    This thesis moves towards reconciliation of two of the major paradigms of artificial intelligence: by exploring the representation of symbolic logic in an artificial neural network. Previous attempts at the machine ...
  • The enumeration of subclasses of the 321-avoiding permutations 

    Li, Jinge
    This thesis is dedicated to the enumeration of subclasses of 321-avoiding permutations, using a combination of theoretical and experimental investigations. The thesis is organised as follows: Chapter 1 provides the necessary ...
  • The New User Problem in Collaborative Filtering 

    Crane, Matthew Stephen
    The new user problem is a problem that all collaborative filtering systems will face. How do we make recommendations when we do not know what the user likes? This thesis provides an overview of collaborative filtering ...
  • The role of social-pragmatic cues in word learning: a neural network model 

    Caza, Gregory Andrew
    Human infants begin to produce speech at the beginning of the second year of life. Some theories propose that language is acquired by simply recognising statistical properties in linguistic input. Other hypotheses consider ...
  • Three Dimensional Reconstruction of Human Lumbar Spine from Bi-planar Radiographs 

    Bennani, Hamza
    This thesis investigates an accurate method for three dimensional (3D) reconstruction of the human spine from bi-planar radiographs with comparable results to CT scans or MRI. In this work, we generated a publicly available ...
  • Towards 3D Scanning from Digital Images by Novice Users 

    Arnott, Reece
    The uptake of hobbyist 3D printers is being held back, in part, due to the barriers associated with creating a computer model to be printed. One way of creating such a computer model is to take a 3D scan of a pre-existing ...
  • Train Localisation using Wireless Sensor Networks 

    Javed, Adeel
    Safety and reliability have always been concerns for railway transportation. Knowing the exact location of a train enables the railway system to react to an unusual situation for the safety of human lives and properties. ...
  • Unsupervised Detection of Emergent Patterns in Large Image Collections 

    Khan, Umair Mateen
    With the advent of modern image acquisition and sharing technologies, billions of images are added to the Internet every day. This huge repository contains useful information, but it is very hard to analyze. If labeled ...
  • Using rough sets to study expert behaviour in induction of labour 

    Parry, David; Yeap, Wai Kiang; Pattison, Neil
    The rate of induction of labour (IOL) is increasing, despite no obvious increase in the incidence of the major indications. However the rate varies widely between different centres and practitioners and this does not seem ...
  • View-based consistency and its implementation 

    Huang, Zhiyi; Sun, Chengzheng; Cranefield, Stephen; Purvis, Martin
    This paper proposes a novel View-based Consistency model for Distributed Shared Memory. A view is a set of ordinary data objects that a processor has the right to access in a data-race-free program. The View-based Consistency ...
