A nonlinear and nonlocal model for animal aggregation
(2022-09-01)An aggregation model is a kind of model used to show the dynamics of the distribution of the population of organisms. Mathematically, we can use a partial differential equation to model the density of an organism at different ... -
Nonlinear vibration analysis of viscoelastic plates with fractional damping
(2017-06-01)Fractional calculus has the history as long as the classical calculus, but up to recent years, less attention has been paid to this method due to its complexity and difficulties in dealing with fractional derivatives and ... -
Nonlinear vibration and chaotic motion of uniform and non-uniform carbon nanotube resonators.
(2014-07-01)Vibration analysis of carbon nanotubes (CNTs) is very essential field owing to their many promising applications in tiny instruments. The unique and interesting properties of CNTs, particularly their mechanical and electrical ... -
Nonlinear vibration and frequency response analysis of piezoelectric-based nanotube resonators
(2015-04-01)To study the vibration behaviour of nanotube-based structures, different models of nanotubes under the effects of piezoelectric layer, intermediate mass, fluid flow and structure curvature are developed. The frequency ... -
A novel deep learning architecture and large-scale benchmark for robust object detection in traffic surveillance and analysis
(2022-12-01)Upstream technologies such as traffic surveillance provide helpful information to downstream intelligent transportation systems intending to improve the safety, mobility, and efficiency of road-users whilst reducing their ... -
Novel electrode materials and advanced electrochemical diagnostics for electrochromic devices
(2022-04-01)Electrochromic materials (ECMs) are a class of “smart” materials used in a variety of applications due to the ability to alter their optical properties with the application of a potential. For these applications, ECMs are ... -
Novel intelligent control techniques in solar-based energy harvesting systems
(2015-10-01)The sun is considered a precious source of energy. Much research has been done to increase our usage from solar energy since it is a renewable source and, most importantly, it is free and green. However in order to use ... -
A novel method of generating Dendritic cells in vitro using the KG-1 cell line and its use as a model for testing effects of lactic acid bacteria
(2011-08-01)Dendritic cells (DCs) are prime mediators of innate and adaptive immunity. In humans the DC population comprise only 0.1% of all leukocytes, making their isolation and ex vivo manipulation difficult. Since study of DC ... -
Novel opposition-based sampling methods for efficiently solving challenging optimization problems
(2011-04-01)In solving noise-free and noisy optimization problems, candidate initialization and sampling play a key role, but are not deeply investigated. It is of interest to know if the entire search space has the same quality for ... -
A novel spatiotemporal framework for efficient traffic prediction and visualization
(2021-12-01)This thesis proposes an efficient traffic prediction framework to estimate congestion at intersections depending on neighboring road links. The framework encompasses three major components, data extraction, Bayesian Linear ... -
Novel tele-operation of mobile-manipulator systems
(2009-08-01)A novel algorithm for the simplified tele-operation of mobile-manipulator systems is presented. The algorithm allows for unified, intuitive, and coordinated control of mobile manipulators, systems comprised of a robotic ... -
Numerical investigation of the fluidelastic instability of two-phase flow in a parallel triangular tube array
(2021-05-01)Steam generators are always susceptible to vibrations induced by the flow in either the shell or tube sides. The fluidelastic instability phenomenon (FEI) is considered one of the most devastating flow excitations since ... -
Numerical investigation of turbulent combustion regimes on localized forced ignition using stratified combustible mixture
(2019-03-01)Localized forced ignition of turbulent stratified mixtures has been numerically analyzed based on three- dimensional Direct Numerical Simulations (DNS) for different values of Karlovitz number (Ka) corresponding to different ... -
Numerical methods for simulating diffusion in cellular media
(2011-12-01)Diffusion imaging is a relatively recent branch of magnetic resonance imaging that produces images of human physiology through diffusion of water molecules within the body. One difficulty in calculating diffusion ... -
A numerical study of the effects of inhomogeneous media in diffusion weighted imaging
(2015-07-01)Diffusion Weighted Imaging (DWI) -a common Magnetic Resonance Imaging (MRI) technique - is used to infer material properties of tissues from the average diffusion of water molecules over brief time intervals. In particular, ... -
Nursing and policy: nurses perspectives on ending hallway healthcare in Ontario
(2022-04-01)Drawing from elements of street-level bureaucracy this thesis examines the experiences and perspectives of six nurses (registered practical nurses and registered nurses) and their work with patients designated as alternate ... -
Object-centric temporal navigation for dynamic information visualizations.
(2014-08-01)We introduce object-centric temporal navigation for time-varying information visualizations. In our approach, navigation through time is controlled by interacting directly with any data item, enabling simultaneous exploration ... -
OLSR-based network discovery in situational awareness system for tactical MANETs
(2012-01-01)In this thesis, we propose a high level design for connectivity visualization of OLSRbased MANET topology based on local topology databases available in an OLSR node. Two different scenarios are considered: a central ... -
