The role of Chief Information Officer (CIO) is a relatively new one and it is evolving. Issues surround the role related to performance, evaluation, and turnover. The investigation reported here is the result of in-depth qualitative interviews with currently practicing CIOs from New Zealand, Taiwan, and the United States. The results are presented in(More)
This paper presents a methodology for tracking a hypo-or hyper-enhanced focal liver lesion (FLL) and a healthy liver region in a video sequence of a Contrast-Enhanced Ultrasound (CEUS) examination. The outcome allows the differentiation between benign and malignant cases, by characterising FLLs of typical behaviour, according to their Time-Intensity curves.(More)
Assessment of focal liver lesions (FLLs) in Contrast-Enhanced Ultrasound requires the delineation of the FLL in at least one frame of the acquired data, which is currently performed manually by experienced radiologists. Such a task leads to subjective results, is time-consuming and prone to misinterpretation and human error. This paper describes an attempt(More)
The aim of this work is to provide an informative evaluation tool to assist clinicians diagnose focal liver lesions (FLLs) in Contrast-Enhanced Ultrasound (CEUS). A methodology to track and characterise a single FLL is presented. We propose a histogram-based motion segmentation approach, in combination with Lowe's SIFT keypoints, to track the locations of(More)
This paper describes a contribution to a wider project which aims to provide an intelligent automated assistant to radiologists performing the skilled and time-intensive task of detecting and characterising cancerous lesions within a human liver from Contrast-Enhanced Ultrasound (CEUS) video sequences. This particular contribution relates to automatically(More)

We describe the development of a speech-driven user interface system, TalkMaths, which enables the dictation of mathematical expressions into electronic documents without the user needing extensive knowledge of any specialized markup language. This system should be of value to many students and teachers, particularly those with disabilities-for whom typing(More)
Computer programming is a highly practical subject and it is essential that those new to the discipline engage in hands-on experimentation as part of the learning process. However, when faced with large cohorts and an increasing demand for distance and student flexible learning, incorporating this into a programming course can be difficult. There is a(More)
We discuss the demand for intelligent systems to assist both teachers and students in the teaching and learning of computer programming, then describe the design, implementation of Nooblab, an integrated system offering instruction, a programming test bed and assessment for several programming languages, and its deployment in real university classroom(More)
