How do species respond to changes in habitat, and can their responses be used to set reliable management targets? The intern’s research is focused on determining whether forest birds respond non-linearly to the loss of forest habitat due to logging. For example, theoretical models show that the probability of finding forest birds within a given patch of forest declines sharply when less than 30% of forest cover remains in the patch. A point of sharp decline in a graph of a particular response to habitat loss is referred to as a 'critical threshold' or 'habitat threshold'.
Eagle Plains Resources is a junior exploration company exploring for minerals in Western Canada. The goal of this project is to understand the nature and type of the copper-goal mineralization present in the Iron Range, Kootenay region of BC.
This project is designed to provide new information on the source of the sediment in the Wernecke Supergroup, a widespread geological formation in northern Yukon that was deposited approximately 1.8 billion years ago. This formation is important because it hosts numerous mineral occurrences that are attracting considerable mineral exploration activity. The source of the sediment will be identified by ion probe analysis on detrital (sedimentary) grains of the mineral zircon.
Rescan Environmental Services has conducted an extended aquatic effects monitoring survey as part of the environmental assessment of the diamond mine operations in northern Canada. Yearly water and sediment samples have been taken over the past 12 years at reference lakes (those not affected by mine operations) and impact lakes (lying in a downstream gradient from the containment facility).
Radical Entertainment is a video game developer which creates and develops games for all current and next generation platforms. Each year, computer games become graphically more realistic due to advances in computer technology and animation. The object of this project is simulation of deformable objects (such as a mattress or jelly-like substances) in real-time for computer gaming purposes. The equations of motion for such objects is quite different and more difficult to solve than those used for rigid bodies.
Radical Entertainment is a video game developer which creates and develops games for all current and next generation platforms. Collision detection forms an indispensable part in today’s 3D game engines. Due to increasing size of the 3D objects used in game development, high-performance collision detection running directly on these objects requires a significant amount of work. To allow for real-time collision detection between a 3D object and other objects in the game environment, the typical approach is to first find for each object a set of best-fitting convex hulls.
Eyeball Networks is a leading developer of software for the VoIP, video telephony and instant messaging industry. In this project, the intern will investigate and model user behavior of VoIP networks developed by the company. Based on a statistical user behavior model, he will then develop a test tool to collect specific Quality-of-Service performance metrics, so as to analyze the scalability of system, and to formulate its relation with the user behavior model.
Machine translation has been an active field in Natural Language Processing. Although the quality of translation cannot reach that of a human, it is getting closer. One of the major sub-tasks in this field is ‘transliteration’, which is mapping the letters from the source language to the letters of target language. It would be useful for translating the proper names, location names and any out-of-vocabulary word found in the source text.
Video games must be able to present things in ‘real time’, with no delays thus performance is critical. A modern processor can deal much quicker with information that is in one continuous section of memory as opposed to divided into smaller chunks. When information is split, it causes a delay in processing. The intern’s research will focus on optimizing a new system for memory management that will attempt to achieve greater performance through a system that organizes memory into collections of whole blocks in order to prevent the need for data to be split.
Video streaming over the Internet is increasing in popularity. Many video objects are made available online and many users are streaming video everyday. In addition, the increasing processing power of personal computers, and the availability of high-speed Internet services, encourages users to demand more, higher-quality video content. To provide high-quality and to accommodate clients with various resources, fine-grained scalable (FGS) video coding has been proposed as part of the recent MPEG-4 and H.264 standards.
