Collection and transcription of a corpus of aphasic speech for the development of a prototype of an intelligent communication aid application

Aphasia is an impairment of language caused by an injury to the brain. Word finding difficulties often accompany aphasia and can persist even after intensive speech therapy, having a negative impact on the person’s social participation and quality of life. Today’s communication aids can improve the ability to effectively communicate but findings from focus groups that we have held show a need for a more intelligent and intuitive communication aid that will better meet individuals’ needs.

Closing the Gap of Write- vs. Read-intensive Data Stores Using SSDs Year Two

Many big data challenges are characterized not only by a very large volume of data that has to be processed but also by a high data production rate. In this project, new storage approaches for big data will be explored. Key point is the efficient use of modern hardware, especially modern storage technology such as SSDs. These new technologies have highly improved performance in comparison to traditional hardware. However, classical data structures and algorithms can not directly be applied due to the different characteristics of these devices.

Using Viral Dynamics to Connect Clinical Markers of Disease Progression to Sequence Evolution for HIV-1

HIV-1 remains a global health challenge, with over 35 million people infected. The high rates of turnover and evolutionary adaptability exhibited by HIV-1 pose a particular challenge to the use of antiretrovirals, as well as the development of a vaccine. Our focus is to understand the dynamics of two of the most commonly tracked clinical markers of an HIV-1 infection: CD4+ T cells/mm3 (CD4 count) and HIV-1 RNA/ml (viral load).

In this project, new storage approaches for big data will be explored. Key point is the efficient use of modern hardware, especially modern storage technology such as SSDs. These new technologies have highly improved performance in comparison to traditional hardware. However, classical data structures and algorithms can not directly be applied due to the different characteristics of these devices. Also, the high cost of the new technology makes their exclusive use uneconomical in many cases.

Smarter Microelectronics Packaging for Performance Scaling

This research project will investigate materials and process behaviors in microelectronic packages that are become increasingly dense and explore novel alternatives to accommodate such densities. When more components are placed and interconnected with each other in smaller and smaller spaces, traditional materials and methods for package assembly become difficult, if not impossible, to replicate.

Detecting Trends in Conversations using Natural Language Processing and Visualization

At WorkSafeBC, an overwhelming amount of data is being produced, particularly in conversation logs between people who have an active claim with WorkSafeBC and various practitioners with whom they have regular contact (usually over the phone). These records are transcribed into text and the information is far beyond what any analyst could possibly read and understand without the help of analysis and visualization tools.

Détection des problèmes dans DB2

L'offre de services sur demande en tout temps entraîne le besoin de cerner et résoudre rapidement des problèmes dans un système de gestion de base de données. Les outils de détection des problèmes dépendent de l'existence d'une quantité de données de surveillance suffisante pour appuyer l'analyse, mais la surveillance introduit des coûts indirects et réduit donc le rendement d'exploitation. Ce projet de recherche vise à produire des outils légers et efficaces pour la surveillance et l'analyse des problèmes au sein des systèmes de gestion de base de données.

Surveillance minimale de DB2

La volonté d’offrir des services 24/7 sur demande signifie qu’il faut pouvoir identifier et résoudre rapidement les problèmes survenant dans un système de gestion de base de données (SGBD). Les outils d’identification des problèmes dépendent de l’existence d’une quantité suffisante de données de surveillance à l’appui de l’analyse mais la surveillance crée un trafic de service et entraîne donc une diminution du rendement de l’application.

Composants logiciels

Les pratiques actuelles de développement logiciel et de réusinage encouragent la programmation modulaire des logiciels et l’interopérabilité des composants logiciels. L’apparition d’architectures axées sur les services encourage maintenant une modularité et une interopérabilité accrues entre logiciels à vendeurs, langages et environnements multiples. L’objectif de ce projet consiste à mieux comprendre ces contraintes croissantes en matière d’interopérabilité dans le contexte d’importantes applications Web.
