Hybrid Organic/Inorganic Optical Upconversion Devices
(University of Waterloo, 2011-12-19)The widely available charge coupled device (CCD) and lately CMOS imaging devices have created many applications on a mass scale. However these devices are limited to wavelengths shorter than about 1 μm. Hybrid photon ... -
Hybrid Path Integral Monte Carlo/Molecular Dynamics Approach for the Simulation of Rigid Rotating and Translating Molecules
(University of Waterloo, 2020-01-23)The path integral formulation of quantum statistical mechanics [1] is widely used for formulating the partition function and diverse thermodynamic properties. The basic objective of this thesis is to present the benchmark ... -
Hybrid Polymer and Peptide-Based Nanostructures for Stimuli-Responsive Drug Delivery
(University of Waterloo, 2014-08-21)Targeting of human tissues by nanomedicines can occur both passively, benefiting from the enhanced permeation and retention (EPR) effect, and actively, through design elements which exploit the unique microenvironment (pH, ... -
Hybrid Semiconductor Detectors for High Spatial Resolution Phase-contrast X-ray Imaging
(University of Waterloo, 2019-02-20)When conventional x-ray radiography presents inadequate absorption-contrast, higher sensitivity can be achieved using phase-contrast methods. The implementation of phase-contrast x-ray imaging using propagation-based ... -
Hybrid Spectral Ray Tracing Method for Multi-scale Millimeter-wave and Photonic Propagation Problems
(University of Waterloo, 2011-10-04)This thesis presents an efficient self-consistent Hybrid Spectral Ray Tracing (HSRT) technique for analysis and design of multi-scale sub-millimeter wave problems, where sub-wavelength features are modeled using rigorous ... -
A Hybrid Symbolic-Numeric Method for Multiple Integration Based on Tensor-Product Series Approximations
(University of Waterloo, 2004)This work presents a new hybrid symbolic-numeric method for fast and accurate evaluation of multiple integrals, effective both in high dimensions and with high accuracy. In two dimensions, the thesis presents an adaptive ... -
A Hybrid Theory of Evidence
(University of Waterloo, 2013-10-28)In the literature on doxastic evidence, the phenomenon is regarded as either internal (Plantinga 1993, Feldman and Conee 2001, Turri 2009) or external (Armstrong 1973, Collins 1997, BonJour 2008). Though the specifics of ... -
Hybrid Thresholds, Redefining the Don River’s Edge
(University of Waterloo, 2015-09-28)My proposal envisions the threshold between the built urban fabric and the natural environment at the water’s edge. It focuses on the development of public space at the water’s edge, and tries to transform that space ... -
Hybrid Time and Time-Frequency Blind Source Separation Towards Ambient System Identi cation of Structures
(University of Waterloo, 2010-08-24)Blind source separation methods such as independent component analysis (ICA) and second order blind identification (SOBI) have shown considerable potential in the area of ambient vibration system identification. The objective ... -
Hybrid Tin Based Nanostructures Wrapped with Graphene as Efficient Anode Material for Lithium Ion Batteries
(University of Waterloo, 2015-08-12)Recently, many developments in the electric & hybrid electric vehicles, and in the electronic devices, have resulted in an increasing demand for high power and high energy density lithium-ion batteries. The current commercial ... -
