Recently haptics became a promising research area applicable to a variety of domains, however, little attention has been paid to haptic interaction with images normally displayed graphically. Furthermore, to our knowledge, no attention has been given to how the addition…

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…

This work addresses the automatic construction of geometric models of real scenes, from multi-view three-dimensional sensor data., We review range data acquisition, multi-view integration, and solid modeling. We show that knowledge about the data acquisition procedure yields not only the…

This thesis deals with the problem of recovering the local structure of surfaces from discrete range data. It is assumed that this recovery is done mostly in a bottom-up fashion, that is, without the help of a priori knowledge about…

High quality, well oriented Zinc Oxide polycrystal thin films on oriented Si crystal surfaces and amorphous SiO$ sb2$/Si, Corning Glass and Al/SiO$ sb2$/Si substrates have been produced by a DC conical reactive S-GUN magnetron sputtering technique. X-Ray diffraction measurements, scanning…

Case-based reasoning is a field of artificial intelligence research that emphasizes the importance of specific past experiences to the solution of new problem. The ability to suggest a solution to a novel problem based on the recall and reuse of…

An object recognition system called ORB1 is proposed and implemented for use on a mobile robot. ORB utilizes the QUADRIS sensor platform developed at the Centre for Intelligent Machines (CIM) at McGill University, which is composed of two BIRIS2 laser…

Action planning ability is essential for autonomous behavior of an intelligent machine. In the robotics domain, planning occurs at different levels of a robotic system; this research targets the problem of planning at the highest level of the hierarchy which…

This dissertation addresses the impact of integrated services on future third generation wireless DS-CDMA networks. The first part of the research characterizes the multiple-access interference (MAI) in an integrated DS-CDMA system. The system model is designed to accommodate bursty packed-based…

This thesis presents a framework for qualitatively representing and reasoning about spatial configurations in the two-dimensional case. The framework contains interval/region based formalisms for describing distances, angles, and locations. These representations lead to the formulation of inference rules, as well…
