Multigrid Methods for Hamilton-Jacobi-Bellman and Hamilton-Jacobi-Bellman-Isaacs Equations
(University of Waterloo, 2011-06-28)We propose multigrid methods for solving Hamilton-Jacobi-Bellman (HJB) and Hamilton-Jacobi-Bellman-Isaacs (HJBI) equations. The methods are based on the full approximation scheme. We propose a damped-relaxation method as ... -
Multilayer Energy Discriminating Detector for Medical X-ray Imaging Applications
(University of Waterloo, 2012-12-04)Contrast-enhanced mammography (CEM) relies on visualizing the growth of new blood vessels (i.e. tumor angiogenesis) to provide sufficient materials for cell proliferation during the development of cancer. Since cancers ... -
A Multilevel Examination of Factors of the School Environment associated with Time Spent in Physical Activity among a sample of Secondary Students in Ontario, Canada.
(University of Waterloo, 2012-01-17)Background: The high prevalence of children and adolescents not meeting the recommended 60 minutes of physical activity (PA) per day and the associated negative health consequences make it critical to increase PA. Ecological ... -
A Multilevel Method for Image Segmentation
(University of Waterloo, 2010-01-18)Image segmentation is a branch of computer vision that has received a considerable amount of interest in recent years. Segmentation describes a process that divides or partitions the pixels of a digital image into groups ... -
Multilevel Monte Carlo for noise estimation in stochastic multiscale systems
(Elsevier, 2018-12-01)The purpose of this study is to adapt Multilevel Monte Carlo (MLMC) sampling technique for random noise estimation in stochastic multiscale systems and evaluate the performance of this method. The system under consideration ... -
Multilingual Grammatical Error Detection And Its Applications to Prompt-Based Correction
(University of Waterloo, 2024-01-05)Grammatical Error Correction (GEC) and Grammatical Error Correction (GED) are two important tasks in the study of writing assistant technologies. Given an input sentence, the former aims to output a corrected version of ... -
Multilingualism and the risk of Alzheimer disease and dementia
(University of Waterloo, 2011-06-16)Background: Alzheimer disease (AD) is a progressive, late-life neurodegenerative disorder. Given the aging population, AD is a significant health concern. According to the Alzheimer Society of Canada (Smetanin et al., ... -
Multilingualism Management at Work: Language Policies, Practices, and Perceptions in German Multinational Corporations. A Case Study.
(University of Waterloo, 2014-09-08)Workplaces are crucial sites for language use within society, where language is linked to economic matters and specific organizational frames. When it comes to multinational businesses, communication is often embedded into ... -
Multimaterial Mesh-Based Surface Tracking
(Association for Computing Machinery, 2014-07-01)We present a triangle mesh-based technique for tracking the evolution of three-dimensional multimaterial interfaces undergoing complex deformations. It is the first non-manifold triangle mesh tracking method to simultaneously ... -
Multimedia Showdown: A Comparative Analysis of Audio, Video and Avatar-Based Communication
(Association for Computing Machinery, 2023-08-03)Our new work culture relies heavily on online meetings and computer-mediated communication (CMC). However, making an online meeting engaging while keeping communication productive is a major challenge. We collected ... -
