Electrostatic MEMS Bifurcation Sensors
(University of Waterloo, 2018-08-24)We report experimental evidence of a new instability in electrostatic sensors, dubbed quasi-static pull-in, in two types of micro-sensors operating in ambient air. We find that the underlying mechanism and features of this ... -
Electrostatic Micro-Tweezers
(University of Waterloo, 2020-06-25)This dissertation presents a novel electrostatic micro-tweezers designed to manipulate particles with diameters in the range of 5-14 μm. The tweezers consist of two grip-arms mounted to an electrostatically actuated initially ... -
Elimination Method of Multi-Criteria Decision Analysis (MCDA): A Simple Methodological Approach for Assessing Agricultural Sustainability
(MDPI, 2017-02-01)In the present world context, there is a need to assess the sustainability of agricultural systems. Various methods have been proposed to assess agricultural sustainability. Like in many other fields, Multi-Criteria Decision ... -
EMG Signal Decomposition Using Motor Unit Potential Train Validity
(University of Waterloo, 2011-09-29)Electromyographic (EMG) signal decomposition is the process of resolving an EMG signal into its component motor unit potential trains (MUPTs). The extracted MUPTs can aid in the diagnosis of neuromuscular disorders and the ... -
EMG-based simultaneous and proportional estimation of wrist/hand kinematics in uni-lateral trans-radial amputees
(BioMed Central, 2012-06-28)We propose a method for estimating wrist kinematics during dynamic wrist contractions from multi-channel surface electromyography (EMG). The algorithm extracts features from the surface EMG and uses dedicated multi-layer ... -
Emotion, Perception and Strategy in Conflict Analysis and Resolution
(University of Waterloo, 2006)Theoretical procedures are developed to account for the effect of emotion and perception in strategic conflict. The <em>possibility principle</em> facilitates modeling the effects of emotions on future scenarios contemplated ... -
An Empirical Model of Area MT: Investigating the Link between Representation Properties and Function
(University of Waterloo, 2018-10-16)The middle temporal area (MT) is one of the visual areas of the primate brain where neurons have highly specialized representations of motion and binocular disparity. Other stimulus features such as contrast, size, and ... -
Empirical validation of the Gamification User Types Hexad scale in English and Spanish
(Elsevier, 2018-10-13)Gamification, the use of game elements in non-game systems, is now established as a relevant research field in human-computer interaction (HCI). Several empirical studies have shown that gameful interventions can increase ... -
Encapsulation and controlled release of vitamin C in modified cellulose nanocrystal/chitosan nanocapsules
(Elsevier, 2021)Vitamin C (VC), widely used in food, pharmaceutical and cosmetic products, is susceptible to degradation, and new formulations are necessary to maintain its stability. To address this challenge, VC encapsulation was achieved ... -
Energy Regeneration and Environment Sensing for Robotic Leg Prostheses and Exoskeletons
(University of Waterloo, 2021-12-23)Robotic leg prostheses and exoskeletons can provide powered locomotor assistance to older adults and/or persons with physical disabilities. However, limitations in automated control and energy-efficient actuation have ... -
Energy Strategies for the Canadian Province of Ontario
(University of Waterloo, 2011-01-24)The current and future energy situations in Canada are put into perspective, and the importance of nuclear energy and controversies surrounding it are investigated. More specifically, to demonstrate the important role ... -
Engineering Social Learning Mechanisms for Multi-Agent Interaction
(University of Waterloo, 2021-09-14)This thesis is strongly inspired by literature on animal social learning, applying it to multi-robot as well as human-robot interaction scenarios, Social learning, which can include complex or simple social mechanisms, ... -
Enhanced detection of point correspondences in single-shot structured light
(University of Waterloo, 2021-09-21)The crucial role of point correspondences in the process of stereo vision and camera projector calibration is to determine the relationship between the camera view(s) and the projector view(s). Consequently, acquiring ... -
Enhancing the Decoding Performance of Steady-State Visual Evoked Potentials based Brain-Computer Interface
(University of Waterloo, 2019-08-14)Non-invasive Brain-Computer Interfaces (BCIs) based on steady-state visual evoked potential (SSVEP) responses are the most widely used BCI. SSVEP are responses elicited in the visual cortex when a user gazes at an object ... -
Ethical Tech Innovation: Uniting Educational Initiatives and Professional Practice
(Social Sciences and Humanities Research Council of Canada, 2021-08)Engineers and other workers at the forefront of technological innovation play a central role in shaping the future of our digital economy, and the COVID-19 pandemic has revealed with stark clarity the urgent need for ethical ... -
