Supporting bodily communication in video consultations of physiotherapy
Physiotherapists are increasingly organising video consultations to support their patients over-a-distance. Physiotherapy is all about movements, and physiotherapists work on improving the subtle differences in the movements ...
Development and evaluation of a semantic-based access framework for health record linkage
Record linkage is the task of finding records in data sources that refer to the same entity across those different resources. In the health domain, record linkage is commonly used for identifying records belonging to the ...
Understanding how cloud computing enables business model innovation in start-up companies
Start-up companies contribute significantly to the national economies of many countries but their failure rate is notably high. Successful start-ups typically depend on innovative business models to be competitive and ...
Erasure codes for optimal performance in geographically distributed storage systems
The amount of digital data generated is overwhelmingly growing. Big data distributed storage systems will require a large storage backbone to store, process and analyse massive volumes of data. Such systems employ cheap ...
Investigating the evolution of structural variation in cancer
Cancers arise from single progenitor cells that acquire mutations, eventually dividing into mixed populations with distinct genotypes. These populations can be estimated by identifying common mutational profiles, using ...
Practical approximation algorithms for clustering and covering
The aim of this thesis is to provide solutions to computationally difficult network optimisation problems on modern architectures. There are three types of problem that we will be studying – clustering, covering and ordering ...
Real and misflagged duplicate question detection in community question-answering
Community question-answering (cQA) sites are websites that people visit to ask or answer questions. Some of these questions are asked repeatedly (although differently worded), resulting in a duplicate effort on the part ...
Indoor localization supported by landmark graph and locomotion activity recognition
Indoor localization is important for a variety of applications such as location-based services, mobile social networks, and emergency response. Although a number of indoor localization systems have been proposed in recent ...
Scalable and accurate forecasting for smart cities
Cities are getting bigger, better and smarter. The increased connectivity of people and devices and the availability of cheap sensors has led to a surge in public and government interest in smart city initiatives. This ...
Analysing the interplay of location, language and links utilising geotagged Twitter content
Language use and interactions on social media are geographically biased. In this work we utilise this bias in predictive models of user geolocation and lexical dialectology. User geolocation is an important component of ...
