(University of Waterloo, 2023-04-12)Preference judging has been proposed as an effective method to identify the most relevant documents for a given search query. In this thesis, we investigate the degree to which assessors using a preference judging system ... -
Investigation of Primary Blast Injury and Protection using Sagittal and Transverse Finite Element Head Models
(University of Waterloo, 2015-01-14)The prevalence of blast related mild traumatic brain injury (mTBI) in recent military conflicts, attributed in part to an increased exposure to improvised explosive devices (IEDs), requires further understanding to develop ... -
INVESTIGATION OF PROTEIN-DRUG INTERACTION USING CAPILLARY ISOELECTRIC FOCUSING WITH WHOLE COLUMN IMAGING DETECTION AND SPECTROSCOPIC TECHNIQUES
(University of Waterloo, 2009-03-26)In this work, the possibilities of understanding protein-drug interactions and the possible modes of action of the drug have been was explored using capillary isoelectric focusing (CIEF) and spectroscopic techniques. The ... -
Investigation of Reactivity Ratios for the AMPS/AAm/AAc Terpolymer and Associated Copolymers
(University of Waterloo, 2015-07-29)Water-soluble polymers of acrylamide (AAm) and acrylic acid (AAc) have significant potential in enhanced oil recovery, as well as in other specialty applications. However, to improve the shear strength of the polymer, it ... -
Investigation of Resistance Spot Weld Failure in Tailored Hot Stamped Assemblies
(University of Waterloo, 2018-01-23)This thesis presents the results from the mechanical characterization of resistance spot welds within hot stamped USIBOR® 1500-AS steel sheet (1.2 and 1.6 mm thickness) with tailored properties. Three parent metal conditions, ... -
Investigation of RF Direct Detection Architecture Circuits for Metamaterial Sensor Applications
(University of Waterloo, 2011-01-19)Recent advances in metamaterials research has enabled the development of highly sensitive near-field microwave sensors with unprecedented sensitivity. In this work, we take advantage of the increase in the sensitivity to ... -
Investigation of Seismic Excitation as a Method for Flow Enhancement in Porous Media
(University of Waterloo, 2008-12-23)The concept of using dynamic excitation to enhance fluid flow in a porous medium began to arise in the mid-twentieth century. The initial spark of interest in the subject spurred numerous laboratory investigations throughout ... -
Investigation of Sf-9 Cell Metabolism Before and After Baculovirus Infection Using Biovolume: a Case for the Improvement of Adeno-Associated Viral Vector Production
(University of Waterloo, 2009-08-07)Adeno-associated viral (AAV) vectors have been shown to be potential vectors for the treatment of diseases, including protocols using RNA interference (RNAi). AAV vector production in insect cells using the baculovirus ... -
The Investigation of Tear Film Osmolality as a Clinical Instrument Used in Assessments of the Tear Film and Dry Eye Disease
(University of Waterloo, 2010-01-11)Introduction: Tear film osmolality is a product of the varying concentrations of dissolved solutes (proteins, lipids and mucins) in the tear fluid. Research suggests that a hyperosmotic tear film is a trait common to ... -
