Role of visual information during stair locomotion
(University of Waterloo, 2011-03-30)Vision provides relevant information for safe locomotion in a variety of environments. During stair locomotion visual information may be important to detect step boundaries, transitions between ground level and stairs, ... -
The Role of Wetland Pond Permanence in the Assembly of Biological Communities in the Prairie Potholes of Alberta
(University of Waterloo, 2020-05-06)Wetlands in the Prairie Pothole Region (PPR) support numerous biological communities, and the composition of these communities depends on the length of time ponded water is present (i.e., hydroperiod or permanence class). ... -
The Role of Working Memory in Deductive Reasoning: A Dual Task and Individual Differences Approach
(University of Waterloo, 2008-08-28)The ‘belief bias’ effect is one of the most pervasive findings in the study of syllogistic reasoning. Here, participants respond “valid” to more believable than unbelievable conclusions, regardless of the actual validity ... -
The Role Volunteer Tourism Plays in Conservation: A Case Study of the Elephant Nature Park, Chiang Mai, Thailand
(University of Waterloo, 2009-10-23)This study examined the role volunteer tourism played in the conservation of elephants in Chiang Mai, Thailand. A case study was conducted to determine whether volunteer tourism at the Elephant Nature Park (ENP) had an ... -
The Roles of Causal Propagator in Relativistic Quantum Information
(University of Waterloo, 2023-05-29)This thesis focuses on the roles of causal propagator — the expectation value of the field commutator — in relativistic quantum information. Consider two observers Alice and Bob, each carrying a two-level quantum system ... -
The Roles of Conserved Dbf4 Motifs in DNA Replication and Checkpoint Responses in Saccharomyces cerevisiae
(University of Waterloo, 2010-01-18)The Dbf4 protein is involved in the initiation of DNA replication, in complex with Cdc7 kinase, and also plays a role in the intra-S-phase checkpoint response via an interaction with Rad53 in Saccharomyces cerevisiae. The ... -
The Roles of Daily and Trait Self-Compassion in Mitigating Symptoms of Bulimia Nervosa: Findings From a Two-Week Daily Diary Study
(University of Waterloo, 2020-08-12)Background: For individuals with bulimia nervosa (BN), eating pathology is largely affected by daily experiences (Crosby et al., 2009). Yet, little is known about protective factors that can mitigate bulimic symptoms ... -
Roman Catholic Women Religious and Organizational Reform in English Canada: The Ursuline and Holy Names Sisters in the Diocese of London, Ontario, 1950-1970
(University of Waterloo, 2007-05-16)Adding to a growing body of research on women and religion in English Canada, this historical study offers a glimpse inside convent culture in 1950s and ’60s Ontario, an area seldom studied by Canadian historians. The ... -
Romantic Attraction towards Men and Women Consistent with Gender Stereotypes: The Role of System and Personal Control Threat
(University of Waterloo, 2010-01-25)During times of economic and political uncertainty, people often feel a lack of control and security. Three studies demonstrate that the motive for a sense of control can increase the desire for a romantic partner who is ... -
Room and Elevated Temperature Constitutive Response of Polycrystalline Materials Exhibiting Tension-Compression Asymmetry under Monotonic Loading
(University of Waterloo, 2014-05-09)A continuum plasticity yield function is developed that captures tension/compression asymmetry and its evolution as exhibited by HCP materials such as magnesium alloy sheet. The model, referred to herein as “CPB06ex3ev”, ... -
Roost Selection and Mass Variation Patterns of Temperate Bats in Eastern Canada
(University of Waterloo, 2021-08-23)Animals are expected to adjust their resource selection and behavioural patterns to improve fitness outcomes, such as fecundity or offspring survival. For long-lived hibernators, decisions made in each annual cycle may ... -
Root-Locus Theory for Infinite-Dimensional Systems
(University of Waterloo, 2007-09-27)In this thesis, the root-locus theory for a class of diffusion systems is studied. The input and output boundary operators are co-located in the sense that their highest order derivatives occur at the same endpoint. It is ... -
RootChord
(University of Waterloo, 2010-04-29)We present a distributed data structure, which we call "RootChord". To our knowledge, this is the first distributed hash table which is able to adapt to changes in the size of the network and answer lookup queries within ... -
Rough Set Based Rule Evaluations and Their Applications
(University of Waterloo, 2007-03-06)Knowledge discovery is an important process in data analysis, data mining and machine learning. Typically knowledge is presented in the form of rules. However, knowledge discovery systems often generate a huge amount ... -
Route Planning and Operator Allocation in Robot Fleets
(University of Waterloo, 2023-10-03)In this thesis, we address various challenges related to optimal planning and task allocation in a robot fleet supervised by remote human operators. The overarching goal is to enhance the performance and efficiency of the ... -
Row-Column Capacitive Micromachined Ultrasonic Transducers for Medical Imaging
(University of Waterloo, 2016-12-14)Ultrasound imaging plays an important role in modern medical diagnosis. Recent progress in real-time 3-D ultrasound imaging can offer critical information such as the accurate estimation of organ, cyst, or tumour volumes. ... -
