Tracing Redox Cycles during Microbe-Clay Interactions Using Stable Iron Isotopes
(University of Waterloo, 2018-10-17)Iron redox cycling, especially Fe(III) reduction, is mostly driven by microbial activity in the shallow subsurface. A wide range of bacteria, archaea, and fungi reduce Fe(III) to acquire energy with soil organic compounds ... -
Ecosystem Services: Linking ecohydrology with economic valuation
(University of Waterloo, 2018-10-17)Economic valuation of ecosystem services has become a dominant model for environmental management at local, regional and global scales. However, policy-makers at all scales take these value estimates with a pinch of salt. ... -
Simulating Farmer Adoption of Agricultural Best Management Practices in the Upper Medway Creek Subwatershed
(University of Waterloo, 2018-10-16)In the coupled human-environment system, humans play a central role in creating various environmental problems, and in turn, are impacted by these environmental consequences. In Canada, water quality degradation caused by ... -
Applications of Stochastic Control to Portfolio Selection Problems
(University of Waterloo, 2018-10-16)Portfolio selection is an important problem both in academia and in practice. Due to its significance, it has received great attention and facilitated a large amount of research. This thesis is devoted to structuring optimal ... -
Each Woman Dies Her Death A Thousand Times: Voices Of Female Experience In The Holocaust
(University of Waterloo, 2018-10-16)While the experiences of Holocaust victims are well studied in history, the nuances of female-centric elements of these experiences have been under-represented in Holocaust historiography until relatively recently. While ... -
“You do realize that I'm like totally winging this?”: Exploring the diagnosis, disclosure and coping experiences of persons living with ALS
(University of Waterloo, 2018-10-16)Background: Amyotrophic Lateral Sclerosis (ALS), an incurable motor neuron disease, primarily affects those between the ages of 60-79, and sees an approximate post-diagnosis life-expectancy of only 2-5 years. The condition ... -
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 ... -
Learning Sparse Orthogonal Wavelet Filters
(University of Waterloo, 2018-10-12)The wavelet transform is a well studied and understood analysis technique used in signal processing. In wavelet analysis, signals are represented by a sum of self-similar wavelet and scaling functions. Typically, the wavelet ... -
Suite Talk: The Barriers and Opportunities of Providing Secondary Suites in Rural Metro-Adjacent Regions of Eastern Ontario
(University of Waterloo, 2018-10-12)Providing an adequate supply of affordable housing has become an increasing challenge for Ontario municipalities. As a result, changes were made to the Planning Act requiring all Ontario municipalities to implement provisions ... -
Electromagnetic Energy Harvesting Surfaces
(University of Waterloo, 2018-10-11)The concept of wireless power transfer (WPT) was successfully demonstrated in the early years of the 20th century. One promising application of using the WPT concept is the WPT transmission utilizing a large array of solar ... -
Multiscale GARCH Modeling and Inference
(University of Waterloo, 2018-10-11)The motivation behind this thesis is the shortage of formal statistical inference methods in the literature for testing whether a time series model is consistent with a sample at multiple sampling frequencies simultaneously. ... -
Wrist and Finger Gesture Recognition with Single-element A-mode Ultrasound signal: A Comparison with Single-channel Surface Electromyogram
(Institute of Electrical and Electronics Engineers, 2018-10-01)With the ability to detect volumetric changes of contracting muscles, ultrasound (US) was a potential technique in the field of human-machine interface (HMI). Compared to the US imaging (B-mode US), the signal from a static ... -
Magnetic nano-nets for capture of microbes in solution based on physical contact
(Elsevier, 2019-02-01)Self-assembly of Au nanoparticles with Fe ions is used to develop magnetic nano-nets similar to fishing nets for capture and removal of microbes in aqueous medium. The nano-nets have a high aspect ratio, span microns in ... -
Access roads impact enzyme activities in boreal forested peatlands
(Elsevier, 2019-02-15)We investigated the impacts of resource access roads on soil enzyme activities in contrasting forested boreal peatlands (bog and fen). In August 2016, a total of 72 peat samples were collected from twelve 20 m long transects ... -
Implications of irradiance exposure and non-photochemical quenching for multi-wavelength (bbe FluoroProbe) fluorometry
(Elsevier, 2018-12-01)Multi-wavelength fluorometers, such as the bbe FluoroProbe (FP), measure excitation spectra of chlorophyll a (Chl-a) fluorescence to infer the abundance and composition of phytoplankton communities as well as the concentration ... -
Perceived timing of active head movement at different speeds
(Elsevier, 2018-11-20)The central nervous system must determine which sensory events occur at the same time. Actively moving the head corresponds with large changes in the relationship between the observer and the environment, sensorimotor ... -
A video-driven model of response statistics in the primate middle temporal area
(Elsevier, 2018-12-01)Neurons in the primate middle temporal area (MT) encode information about visual motion and binocular disparity. MT has been studied intensively for decades, so there is a great deal of information in the literature about ... -
