Power Modelling in Multicore Computing
Power consumption has long been a concern for portable consumer electronics, but has recently become an increasing concern for larger, power-hungry systems such as servers and clusters. This concern has arisen from the ... -
Prolific structures in combinatorial classes
Under what circumstances might every extension of a combinatorial structure contain more copies of another one than the original did? This property, which we call prolificity, holds universally in some cases (e.g., finite ... -
Protocol Support for Adaptive Streaming Media
The Internet has already become a platform for multimedia rich communication, collaboration and entertaining applications. A majority of these applications are based on a technology known as audio-video streaming. Streaming ... -
QoS-based Handover for Next Generation Wireless Networks
The deployment of the Next Generation Wireless Network (NGWN) involves different service providers, different radio access technologies and multi-mode mobile terminals that have to be compatible with existing services and ... -
Reading the brain’s personality: using machine learning to investigate the relationships between EEG and depressivity
Electroencephalography (EEG) measures electrical signals on the scalp and can give information about processes near the surface of the brain (cortex). The goal of our research was to create models that predict depressivity ... -
Receiver Driven Email Delivery
Spam has become a serious problem to email users all over the world. Most of the daily email messages we are receiving consists of unwanted spam messages. Although there are various methods to reduce the quantity of spam ... -
Red blood cell segmentation using guided contour tracing
We present a model-based contour tracing approach to the problem of automatically segmenting a Scanning Electron Microscope image of red blood cells. These images characteristically have high numbers of overlapping cells ... -
Removing a Single Brick From The Language Barrier Between Us and Information
Information is one of the most valuable resources we have, and the primary way we access information nowadays is via search engines. Unfortunately, written language is rife with inconsistencies and ambiguity, which can ... -
Routing and Wavelength Assignment for Multicast Communication in Optical Network-on-Chip
An Optical Network-on-Chip (ONoC) is an emerging chip-level optical interconnection technology to realise high-performance and power-efficient inter-core communication for many-core processors. Within the field, multicast ... -
Self localisation in indoor environments using machine vision
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
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 ... -
Sensor Evaluation for Voxel-Based RGB-D SLAM
The introduction of the Kinect sensors by Microsoft sparked a productive period of research in the application of RGB-D (colour and depth) cameras. With the original two versions of the Kinect sensors discontinued, a number ... -
Some neuro-computational investigations into the reviewing of object-files
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, ... -
Spaces of phylogenetic time trees
Time trees are evolutionary histories (also called phylogenies) that include times of evolutionary events. They arise in many applications, including cancer and virus evolution. Of particular interest are clock-like trees, ... -
Spatial data acquisition from motion video
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
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
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
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
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
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 ...
