Word prediction in assistive technologies for Aphasia rehabilitation in using Systemic Functional Grammar
… speech language pathologists. While Augmentative and Alternative Communication (AAC) devices have made identifiable progress in providing support which is able to be managed by the individual, language production tasks are often challenged by the limitations brought about by aphasia. What follows …

Personalized News Recommender using Twitter
… profiles are built based on the user's interests and the news articles are ranked by matching the characteristics of the user profile. With the help of these two approaches, we present a hybrid news recommendation model that recommends interesting news stories to the user based on their popularity …

Probabilistic Roadmaps for Virtual Camera Pathing with Cinematographic Principles
<p>As technology use increases in the world and inundates everyday life, the visual aspect of technology or computer graphics becomes increasingly important. This thesis presents a system for the automatic generation of virtual camera paths for fly-throughs of a digital scene. The sample scene used …

Physics Engine on the GPU with OpenGL Compute Shaders
<p>Any kind of graphics simulation can be thought of like a fancy flipbook. This notion is, of course, nothing new. For instance, in a game, the central computing unit (CPU) needs to process frame by frame, figuring out what is happening, and then finally issues draw calls to the graphics …

Eulerian on Lagrangian Cloth Simulation
… difficult cloth scenarios, such as draping and sliding cloth over sharp features like the edge of a table. A traditional Lagrangian approach models a cloth as a series of connected nodes. These nodes are free to move in 3d space, but have difficulty with sliding over hard edges. The cloth …

A comparison of the effects of reading from a VDU and from paper as measured in terms of reading speed and comprehension
This study investigates the legibility and visual effects of eight combinations of font and colour on VDU and two different fonts on paper. Forty subjects, sixteen females and twenty-four males, were exposed to three of the ten different conditions, one in each of the set of readings, on either VDU …
