A variational approach to mapping: an exploration of map representation for SLAM
(2012-07-01)Simultaneous Localization and Mapping (SLAM) algorithms are used by autonomous robots to build or update maps of an environment while maintaining their position simultaneously. A fundamental open problem in SLAM is the e ... -
Vector occluders: an empirical approximation for rendering global illumination effects in real-time
(2013-02-01)Precomputation has been previously used as a means to get global illumination effects in real-time on consumer hardware of the day. Our work uses Sloan’s 2002 PRT method as a starting point, and builds on it with two new ... -
Vehicular infotainment forensics: collecting data and putting it into perspective
(2017-01-01)In today’s transportation system, countless numbers of vehicles are on the road and later generations have become mobile computers. Vehicles now have embedded infotainment systems that enable user-friendliness and ... -
Video game livestream spectator: motivations and behaviours
(2021-12-01)In recent years, video game livestreams have seen tremendous growth, resulting gaps of knowledge regarding studies on the motivations and behaviours of livestream spectators. This thesis presents two studies that intend ... -
Virtual drilling haptics perception from auditory cues employing low-end haptic devices
(2018-12-01)Simulation-based training is being widely adopted in medical education because it allows exposing trainees to safe and controlled simulated scenarios otherwise impossible to reproduce in real life. Current advances in ... -
Virtual machine detection through Central Processing Unit (CPU) detail anomalies
(2022-12-01)Malware analysts commonly use virtual machines to provide safe environments to study malware. Malware authors in response, include virtual machine detection functions in their malware so it changes its behavior should a ... -
A Vision-Based System For Non-Intrusive Posture Correction Notifications
(2021-05-20)Sedentary lifestyle and the prolonged sitting associated with it may have negative health consequences and poor sitting posture only exacerbates that. In this thesis I propose a software application for monitoring a computer ... -
Visual Analytics for Topic Model Optimization based on User-Steerable Speculative Execution
(IEEE, 2018-09-18)To effectively assess the potential consequences of human interventions in model-driven analytics systems, we establish the concept of speculative execution as a visual analytics paradigm for creating user-steerable preview ... -
Visual encoding quality and scalability in information visualization
(2019-02-01)Information visualization seeks to amplify cognition through interactive visual representations of data. It comprises human processes, such as perception and cognition, and computer processes, such as visual encoding. ... -
Visualization and the Digital Humanities: Moving Toward Stronger Collaborations
(IEEE, 2018-12-01)For the past two years, researchers from the visualization community and the digital humanities have come together at the IEEE VIS conference to discuss how both disciplines can work together to push research goals in their ... -
Visualization, Digital Humanities, and the Problem of Instrumentalism
(2021-06-01)In this paper we present the concept of “slow analytics” that attempts to ridge the gap between humanities tasks and visualization. Often within Technological disciplines the pursuit of speed and efficiency are paramount. ... -
Vixen: a games user research tool for collection and interactive visualization of usertesting data
(2017-08-01)Visualization techniques can facilitate the understanding and exploration of relationships in usertesting data. For example, data from players' in-game movement can be combined with interview data or questionnaire results. ... -
Water quality and biotic community response to an urban – rural land-use gradient in the Lake Simcoe watershed
(2020-06-01)Most research in the Lake Simcoe watershed (LSW) has focused on how the lake has responded to changes in nutrients sourced by agriculture, particularly after mitigation measures have been put in place to remedy the lake’s ... -
Webcasting Made Interactive: Persistent Chat for Text Dialogue During and About Learning Events
(Springer, 2007)This paper presents a “persistent chat” extension to the ePresence Interactive Media webcasting infrastructure to support real-time commenting on and discussing of issues that arise during a learning event, followed by ... -
The World Trade Web: using network analysis and machine learning as tools for public policy decision-making
(2020-11-01)The World Trade Web (WTW) contains a wealth of information that upon rigorous analysis can aid governments in public policy decision-making. In my attempt to provide this valuable input, this dissertation uses two main ...
