Improving Query Performance on Database Free-Text and Semi-Structured Text Columns

The project deals with the better indexing of text fields in the database. It explores an idea of on-line maintenance of an inverted index, which is built for the tokens of the text content in the database. The on-line update of such an index is currently considered impractical. We try to overcome this inverted index update bottleneck with the use of B-tree data structure and the specially designed in-memory buffer. In case of success, this on-line indexing will highly improve the performance of user queries on database text fields.

Audio Zoom: blind source separation in a reverberant environment

Dr. Peter Driessen’s research group at University of Victoria is working on building a system using microphone arrays of arbitrary geometry to zoom in on desired audio in a noisy environment. Ultimately a listener will be able to simply look at the location from where s/he wants to hear the audio, controlling the audio zoom via head and eye gestures.

Performance Evaluation of Vehicular Networks

This is an extension of our research project, Network Connectivity in Vehicular Ad Hoc Networks, which involved a MITACS Globalink intern student in Summer 2010. Vehicular networks, in either vehicle-to-vehicle (V2V) or vehicle-to-infrastructure

Investor Return Calculations for an Evaluation of the British Columbia Equity Capital Program

The MITACS intern will help the partners at the Rocket Builders Canada Ltd. and the University of Victoria to evaluate the B.C. equity capital program (ECP) administered under the British Columbia Small Business Venture Capital Act. The main deliverables of the MITACS intern are to: (1) estimate the returns of investors under the equity capital program, (2) estimate the amount of capital gains tax the ECP has or will generate, and (3) perform a “survival analysis” of the companies that benefited from the ECP since the year 2000.

Quasi-Experimental Study of a Community-Based, Collaborative Nutrition Education Initiative

The gNutrition for Youh initiative is a recent and unique partnership sponsored by Thrifty Foods, and delivered through 18 municipal recreation centres, with Springwell Nutrition Group, and evaluated by the University of Victoria. In 2008]09, over 1,300 participants attended education seminars. More than 225 also attended grocery stores tours. Process evaluation data suggested that the initiative was very well received.

On-Demand Expansion of eBusiness Services to the Cloud

The project will help eBusiness service providers to react faster and more economically to changing demands on their IT services. The goal is to develop automated techniques to utilize off-site computing resources that are offered on the Internet (so-called cloud computing resources), whenever there is a particularly high demand on the company internal computing infrastructure. The cloud computing resources can be used to temporarily augment the internal infrastructure.

Knowledge Translation: Nursing Uptake and Patient Outcomes Examined

Best practice guidelines are vital resources in the provision of consistent and equitable cancer care by Registered Nurses. However, best practice guidelines are not readily used in cancer care and when they are available, this use is inconsistent. Previous research about the use and impact of practice guidelines has focused on the problems of professionals (mostly nurses and physicians) or the workplace itself. The purpose of this project is to use the expertise and knowledge of Registered Nurses while studying the interactions of the many different people involved in patient care (e.g.

Application of a "Knowledge to Action" Approach with Two BC Health Authorities in a Study to Design Psychometric Instrument of Collaborative Team Culture

This internship augments a post-doctoral study to design psychometric instrumentation for measurement and evaluation of collaborative team culture. The study builds upon a dissertation inquiry carried out by the applicant, in which a collaborative health care culture framework was developed. There are insufficient evaluation tools to measure collaborative team culture and this study addresses this deficit.
