The majority of people affected by Multiple Sclerosis (paMS) experience severe and disabling fatigue. A recent randomised controlled trial (RCT) showed that cognitive behaviour therapy with a clinical psychologist was an effective treatment for MS fatigue. An Internet-based version of this intervention, MS Invigor8, was developed for the current study using(More)
The Cloud Computing Business Framework (CCBF) is proposed to help organisations achieve good Cloud design, deployment, migration and services. There are four key areas to be addressed: (i) Classification; (ii) Organisational Sustainability Modelling (OSM); (iii) Service Portability and (iv) Linkage. Each area’s focus is described, and we explain how each(More)
A considerable number of serious games have been developed over the last ten years, with varying degrees of success. Due to a lack of clear standards and guidelines for game developers, it is difficult to justify claims that a specific game meets the learner’s requirements and/or expectations. This paper defines a conceptual model for serious games that(More)
IMS QTI is a popular and important standard for e-learning assessment. The second version of the standard (QTIv2) works alongside other IMS standards, but take-up has been slow, with problematic implementations and no definitive reference software. The R2Q2 project aims to produce a set of loosely coupled web services that will provide definitive reference(More)
Patient education materials and hospital forms are given to patients with little regard for their ability to read them. Nationwide sampling and data from the 1980 census suggest that a high proportion of patients cared for in public hospitals are functionally illiterate. In this study, 151 adult primary care patients in five different ambulatory care(More)
This paper reviews current cloud computing business models and presents proposals on how organisations can achieve sustainability by adopting appropriate models. Using the Jericho Forum’s Cloud Cube Model (CCM), we classify cloud computing business models into eight types: (1) Service Provider and Service Orientation; (2) Support and Services(More)
Cloud Computing Business Framework (CCBF) is proposed to help organisations achieve good Cloud design, deployment, migration and services. While organisations adopt Cloud Computing for Web Services, technical and business challenges emerge and one of these includes the measurement of Cloud business performance. Organisational Sustainability Modelling (OSM)(More)
This paper describes the advantages of using the anomaly detection approach over the misuse detection technique in detecting unknown network intrusions or attacks. It also investigates the performance of various clustering algorithms when applied to anomaly detection. Five different clustering algorithms: k-Means, improved k-Means, k-Medoids, EM clustering(More)
Interest in educational gaming is on the rise once again, and particular interest has started to peak in the area of lightweight educational mini-games. But are these games really as useful as people suggest, or are they simply too shallow to convey sufficient pedagogical meaning? And how do we assess how well these games measure up as educational(More)
This paper demonstrates financial enterprise portability, which involves moving entire application services from desktops to clouds and between different clouds, and is transparent to users who can work as if on their familiar systems. To demonstrate portability, reviews for several financial models are studied, where Monte Carlo Methods (MCM) and Black(More)
