The REFRESH Study Recreation Environment and Food Research: Experiences from Hockey
(University of Waterloo, 2017-03-03)Introduction Unhealthy dietary behaviours are prevalent among adolescents who participate in organized sports. This may be putting them at risk of obesity and chronic disease, since adolescent eating behaviours have been ... -
The Refutation of Magic in the Dərsanat of Zärʾa Yaʿəqob
(University of Waterloo, 2017-05-15)The 15th century Ethiopian Emperor Zärʾa Yaʿəqob (r. 1434-1468) is perhaps the most influential figure in the almost 1700 year history of the Ethiopian Church. One would be hard-pressed to name an individual who can match ... -
Regenerative and Adaptive Shock Absorber: A Hybrid Design
(University of Waterloo, 2014-05-15)Damping in a multitude of engineering applications has a variable threshold requirement based on the input excitation given to the system. In most applications the desired system response is known but the input to the ... -
Regime Shift Detection Techniques for Determining the Year of Positive 0°C Crossing in the Northern Hemisphere for Late-Winter and Spring
(University of Waterloo, 2011-12-21)The temperature of 0°C, the phase change point of water-ice, is among the most influential factors on the hydrology of the temperate regions that experience winter. Many cryospheric processes, such as snow and ice melt, ... -
Regime Switching and Technical Trading with Dynamic Bayesian Networks in High-Frequency Stock Markets
(University of Waterloo, 2009-05-23)Technical analysis has been thwarted in academic circles, due to the Efficient Market Hypothesis, which had significant empirical support early on. However recently, there is accumulating evidence that the markets are not ... -
A Region at Odds: Abortion Politics in the Maritime Provinces, 1969-1988
(University of Waterloo, 2015-10-01)The inaccessibility of abortion services in the Maritime Provinces remains a constant topic in the media, and yet little research has been conducted to explain the barriers to the procedure in the region. Despite many ... -
A Region in Transition: The Role of Networks, Capitals and Conflicts in the Rainy River District, Ontario.
(University of Waterloo, 2010-04-15)This research analyzed declining resource-based communities in the Rainy River District, Ontario, that is typical of the Canadian middle north, and explored their central features using several qualitative and participatory ... -
Regional Cerebral Blood Flow Differences Between the Middle Cerebral Artery and the Basilar Artery
(University of Waterloo, 2017-09-27)Much of the research that has investigated cerebral circulation has used the MCA and has assumed that it is an indicator of what is happening in all regions of the brain. Yet little research exists to validate this notion. ... -
A Regional Electricity Hub for Energy Transitions
(University of Waterloo, 2018-07-10)The transition to a low-carbon energy economy will remain a cornerstone of national energy policies of countries committed to the climate change accord for decades to come. We highlight the need for transmission investment ... -
Regional Frequency Analysis Estimates of Extreme Rainfall Events under Climate Change
(University of Waterloo, 2020-01-09)Extreme rainfall events have a long history of causing large economic damages in urban areas and even loss of human life. Reliable estimates of extreme rainfall intensities for different rainfall durations are essential ... -
The Regional Integration of Protected Areas: A Study of Canada's National Parks
(University of Waterloo, 2008-08-01)The relationship between protected areas and their regions is complex, dynamic, and often based on social interactions. It is widely accepted that protected areas are not “islands” – rather they are connected to their ... -
Registering a Non-Rigid Multi-Sensor Ensemble of Images
(University of Waterloo, 2009-09-29)Image registration is the task of aligning two or more images into the same reference frame to compare or distinguish the images. The majority of registration methods deal with registering only two images at a time. Recently, ... -
Regular Dilation on Semigroups
(University of Waterloo, 2018-08-07)Dilation theory originated from Sz.Nagy's celebrated dilation theorem which states that every contractive operator has an isometric dilation. Regular dilation is one of many fruitful directions that aims to generalize ... -
Regular Pattern Detection and Analysis Using Shapelets
(University of Waterloo, 2014-10-27)The presence of regular patterns in natural and technological phenomena is pervasive, often being present in both time and space. To increase our understanding of many phenomena where patterns are present, measurable ... -
Regularization Using a Parameterized Trust Region Subproblem
(University of Waterloo, 2004)We present a new method for regularization of ill-conditioned problems that extends the traditional trust-region approach. Ill-conditioned problems arise, for example, in image restoration or mathematical processing of ... -
Regularized Autoregressive Approximation in Time Series
(University of Waterloo, 2008-05-25)In applications, the true underlying model of an observed time series is typically unknown or has a complicated structure. A common approach is to approximate the true model by autoregressive (AR) equation whose orders are ... -
Regularizing Deep Models for Visual Recognition
(University of Waterloo, 2016-10-26)Image understanding is a shared goal in all computer vision problems. This objective includes decomposing the image into a set of primitive components through which one can perform region segmentation, region labeling, ... -
Regulation of a cold inducible antifreeze protein in soil bacterium Pseudomonas putida GR12-2
(University of Waterloo, 2014-09-30)In cold inhabiting bacteria, a commonly used strategy to combat freezing stress is the production of antifreeze proteins. These proteins assist in survival below 0 degrees Celsius by minimizing extracellular ice crystal ... -
Regulation of Heat Shock Protein 70 Levels in Red Blood Cells of Rainbow Trout
(University of Waterloo, 2010-10-28)The physiological responses to stressor exposure can be broadly grouped into the organismal and the cellular stress responses. The organismal stress response involves the release of hormones into general circulation, while ... -
Regulation of Hysteretic Systems with Preisach Representation
(University of Waterloo, 2009-09-30)Piezoelectric actuators are well suited for high precision mechanical and electrical engineering applications. However, its performance in regulator configurations has been limited due to hysteresis. The hysteresis in these ...
