Analysis of Reliability of Fueling Machine Head Encoders
(University of Waterloo, 2022-01-10)The objective of this thesis is to investigate in-service performance and reliability of four principal encoders used to guide the motion of the fueling machine (FM), which is used to support the fueling operation in a ... -
Bayesian Inference of Stochastic Degradation Models: A Likelihood-Free Approach
(University of Waterloo, 2021-09-03)The structural integrity and system performance of large engineering systems are adversely affected by various forms of degradation mechanisms. Modeling of such mechanisms is accomplished by collecting degradation data ... -
Condition Assessment of Concrete Elements through Two Nondestructive Ultrasonic Techniques
(University of Waterloo, 2017-07-13)Reinforced concrete is one of the materials most used in civil infrastructure, and the expected service life is generally for several decades. However, as any other material, concrete performance is affected by environmental ... -
Development of Probabilistic Finite Element Models for Assessment of Deformation in CANDU Fuel Channels
(University of Waterloo, 2022-01-07)Fuel channels (FCs) are one of the most critical components in a CANDU reactor. A FC comprises a Pressure Tube (PT), a Calandria Tube (CT) and four garter springs and it acts as the pressure boundary between the “hot” heavy ... -
Direct Method of Generating Floor Response Spectra
(University of Waterloo, 2016-05-12)Floor Response Spectra (FRS), also called In-structure Response Spectra (IRS) in some standards and literature, are extensively used as seismic input in safety assessment for Systems, Structures, and Components (SSCs) in ... -
Direct Method of Generating Floor Response Spectra for Structures under Earthquake Excitations at Multiple Supports
(University of Waterloo, 2023-05-15)Floor Response Spectra (FRS) are commonly used as seismic input in the safety assessment for secondary systems in the nuclear power industry. Efficient and accurate determination of FRS is crucial in the design of nuclear ... -
Excitation Force and Frequency Effects in Wave-Based Techniques for the Characterization of Geomaterials at Different Scales
(University of Waterloo, 2020-10-06)All around the world, building codes require the characterization of geomaterials as a fundamental step in the foundation design process. Specifically, in seismic design, the evaluation of dynamic properties is a key ... -
An Investigation of Non-stationary Nature of Environmental Data
(University of Waterloo, 2019-04-17)Several investigations have shown that the Earth's climate is experiencing change, as evident by rising global temperatures, receding ice sheets and reducing glacier sizes. There is also empirical observation supporting ... -
Machine Learning Based Data Driven Modelling of Time Series of Power Plant Data
(University of Waterloo, 2020-04-28)Accurate modeling and simulation of data collected from a power plant system are important factors in the strategic planning and maintenance of the unit. Several non-linearities and multivariable couplings are associated ... -
A Probabilistic Corrosion Model for Copper-Coated Used Nuclear Fuel Containers
(University of Waterloo, 2022-08-18)Lifetime predictions of used nuclear fuel containers destined for permanent storage in Deep Geological Repositories (DGRs) are challenged by the uncertainty surrounding the environment and the performance of both containers ... -
Probabilistic Finite Element Analysis of Structures using the Multiplicative Dimensional Reduction Method
(University of Waterloo, 2015-12-23)It is widely accepted that uncertainty may be present for many engineering problems, such as in input variables (loading, material properties, etc.), in response variables (displacements, stresses, etc.) and in the ... -
Probabilistic Life Cycle Assessment of Safety Valves
(University of Waterloo, 2020-05-14)The objective of this this thesis is to develop a probabilistic model for assessing the life cycle performance of safety valves used in the nuclear piping system. The life cycle performance is quantified in terms of ... -
Reliability Analysis Using the Method of Multiplicative Dimensional Reduction
(University of Waterloo, 2017-04-25)Traditional engineering analyses and designs are based on deterministic input variables, and variability seen in the real world are often ignored to simplify the work. Formal reliability analyses are generally avoided by ... -
