Teaching Computer Vision using Primary Source Material

Computer vision is a very broad and rapidly-changing eld. A major challenge for teachers of this subject is to cover a large body of basic theory while at the same time giving a good sense of state-of-the-art research. Traditionally our fourth year undergraduate course in computer vision was taught using lectures and textbooks. We report on the results of altering the course so that it focused ...

Oxygen concentrators: a primary oxygen supply source.

PURPOSE Efforts to harmonize the standards of the CSA and the ISO, as they relate to compressed medical gas supply and piping, prompted us to review ten years experience with oxygen concentrators (OCs) in Canada used as a primary hospital oxygen supply. The goals of this study were; 1) To document the number of Canadian OC Hospital sites, 2) to define what impact these units have had on medical...

A note concerning Primary Source Knowledge

We add a small increment to understanding the notion of ‘Primary Source Knowledge’ (PSK). PSK is knowledge that the non-expert and the citizen can acquire by assiduously reading the primary scientific journal literature without being embedded in the cultural life of the corresponding technical specialty (Collins and Evans 2007). This comes from exposing four papers to the automated computer fil...

Primary Source Correction (PSC) in Wave Field Synthesis

The theory of wave field synthesis is traditionally derived based on the Kirchhoff-Helmholtz integral equation for bounded volumes with continuous secondary point source distributions on the boundary area. Usually, a secondary source distribution on a boundary contour is used in practical implementations and the theory is adapted by reducing the geometry to two dimensions, employing secondary l...
