The purpose of this thesis is to evaluate the medical data management expert system at the Pediatric Intensive Care Unit of the Montreal Children's Hospital. The objective of this study is to provide a systematic method to evaluate and, progressively…

In this thesis, the concept of an intelligent system for the design and planning of electric power systems is developed. Such a system serves to preserve the vast body of power system design knowledge by identifying, structuring and consolidating it…

In the context of teleoperated mobile robotics, the use of video data is one of the most desirable sensing modalities for vehicle guidance. Unfortunately, maintaining reliable noise-free video transmission, especially in cost sensitive teleoperation applications is a frequent problem., We…

Autonomous robotic operation in an unstructured or partially known environment requires sensing and sensor-based control. To overcome the problems with current "eye-in-hand" systems, miniature amplitude-based, infra-red proximity sensors are being studied. Obtaining position and velocity estimates of a rigid body…

A prototype electrostatic imager has been developed for megavoltage portal imaging in radiation therapy. The imager utilizes amorphous selenium (a-Se) with a front metal plate as the imager receptor and a high resolution voltmeter probe for image readout. Imaging characteristics…

New digital communication applications, such as multimedia, require very powerful error correcting codes that deliver low error rates while operating at low to moderate ratios (SNRs). Turbo codes have reasonable complexity and can achieve very low error rates if a…

In this thesis, we present two new methods to overcome the effects of both camera calibration errors and partial emptiness of surface voxels in voxel-coloring. Voxel-coloring is a relatively new volumetric method for 3D scene reconstruction from multiple calibrated views.…
