Nondestructive Evaluation of Asphalt Pavement Joints Using LWD and MASW Tests
(University of Waterloo, 2010-09-16)Longitudinal joints are one of the critical factors that cause premature pavement failure. Poor-quality joints are characterized by a low density and high permeability; which generates surface distresses such as ravelling ... -
Nondestructive Evaluation of the Depth of Cracks in Concrete Plates Using Surface Waves
(University of Waterloo, 2009-04-16)Concrete structures can often be modeled as plates, for example, bridges, tunnel walls and pipes. Near-surface damage in concrete structures mostly takes the form of cracking. Surface-breaking cracks affect concrete ... -
Nondifferentiable energy minimization for cohesive fracture in a discontinuous Galerkin finite element framework
(University of Waterloo, 2019-05-23)Until recently, most works on the computational modelling of fracture relied on a Newtonian mechanics approach, i.e., momentum balance equations describing the motion of the body along with fracture criteria describing the ... -
Noninvasive Glucose Detection Using Infrared Photoacoustic Spectroscopy and Machine Learning
(University of Waterloo, 2023-12-19)The ideal method to monitor diabetes is to obtain the glucose level with a fast, accurate, and pain-free measurement that does not require blood drawing or finger pricking. Although the development of noninvasive devices ... -
Nonlinear Analysis of Reinforced Concrete Frames Subjected to Abnormal Loads
(University of Waterloo, 2007-09-20)The purpose of this study is to analyze reinforced concrete frames subjected to abnormal loads. Structures are rarely subjected to abnormal loads, however, when they are subjected to them, it can lead to a progressive ... -
Nonlinear and Geometric Controllers for Rigid Body Vehicles
(University of Waterloo, 2018-10-18)In this thesis we investigate the motion control problem for a class of vehicles C V , which includes satellites, quadrotors, underwater vehicles, and tailsitters. Given a globally represented model of C V , and a curve, ... -
Nonlinear Behavior of Unstable Black Holes in Anti-de Sitter Spacetimes
(University of Waterloo, 2020-09-25)The nonlinear dynamics of black holes is an increasingly relevant topic of which little is known. In this thesis, we study the full nonlinear dynamics of black holes, as well as their linear behavior, and combine them ... -
Nonlinear Dimensionality Reduction by Manifold Unfolding
(University of Waterloo, 2013-09-27)Every second, an enormous volume of data is being gathered from various sources and stored in huge data banks. Most of the time, monitoring a data source requires several parallel measurements, which form a high-dimensional ... -
Nonlinear Dimensionality Reduction with Side Information
(University of Waterloo, 2006)In this thesis, I look at three problems with important applications in data processing. Incorporating side information, provided by the user or derived from data, is a main theme of each of these problems. <br /><br ... -
Nonlinear Finite Element Analysis of Influence of Support Geometry on the Punching Shear Behaviour of Reinforced Concrete Slabs
(University of Waterloo, 2023-06-23)Due to their many benefits including ease of construction, open floor plans and reduced cost reinforced concrete flat slabs are one of the most common structural systems. However, these systems, particularly flat slabs ... -
Nonlinear Finite Element Analysis of Punching Shear of Reinforced Concrete Slab-Column Connections
(University of Waterloo, 2016-01-08)The code provisions for the design of reinforced concrete slabs are based on empirical and mostly statistical formulations derived from the tests. The available testing database consists of different types of slabs and in ... -
Nonlinear Finite Element Analysis of Punching Shear of Reinforced Concrete Slabs Supported on Rectangular Columns
(University of Waterloo, 2018-08-22)Historical and current design code provisions for the punching shear of reinforced concrete slabs supported on rectangular columns vary greatly and are primarily based on empirical results. Additionally, the existing ... -
