Neutronic characterization of a Molybdenum-99-producing CANDU fuel bundle and implications for reactivity-device worth and refuelling strategies
(2023-08-01)
Operating CANDU reactors can potentially produce significant quantities of Molybdenum-99 due to their ability to be refuelled online, high thermal neutron flux and fuel-design flexibility. A Molybdenum-producing bundle ...
Developing an elevated temperature Pourbaix diagram for zirconium and multi-element Pourbaix diagram of Zircaloy-4
(2023-08-01)
Zirconium and Zircaloy-4 are used in applications that require corrosion resistance under extreme conditions. For example, the fuel bundles in coolant systems of CANDU™ reactors operate between 533 to 583K (260 to 310 °C). ...
Towards improving the usability of system-assigned PINs: can implicit learning techniques help?
(2023-08-01)
Personal Identification Numbers (PINs) are widely used for automated teller machines (ATMs), computers, mobile devices, debit cards, and credit cards. People tend to choose easy-to-recall PINs that are related to important ...
Sidewalk extraction using deep learning and cost-based route optimization with mini-max objective function
(2023-12-01)
With the growing diversification of modern urban transportation options, such as small-scale autonomous delivery vehicles, autonomous patrol robots, e-bikes, and e-scooters, sidewalks have gained newfound importance as ...
A proof of principle nuclear forensics technique for determining ²³⁵U enrichment from UF₆ steel cylinders
(2023-12-01)
Non-proliferation of nuclear materials depends on international regulations and the inspection tools available to safeguard inspectors for ensuring adherence to international treaties such as the Non-Proliferation Treaty ...
Navigating life with heart failure: the realities of self-care practices for patients and their families following cardiac rehabilitation
(2023-12-01)
Heart failure (HF) self-care is well-documented in HF management, yet the experiences of patients and family members post-cardiovascular rehabilitation (CR) are less explored. This qualitative study utilized semi-structured ...
An investigation into the use of ConvNext within IICS/IIDS framework for person Re-ID
(2023-05-01)
In this thesis, we explore the integration of ConvNeXt, a CNN-based network inspired by vision transformers, into the Intra and Inter Camera Similarity (IICS) and Intra and Inter Domain Similarity (IIDS) frameworks for ...
Investigation of integrated energy systems with carbon capturing and chemical looping units for hydrogen, methane and methanol production
(2023-11-01)
This study investigates three multigeneration systems designed for hydrogen generation through chemical looping, incorporating an amine-based carbon dioxide capture subsystem. These systems consist of a solar tower heating ...
Discovery of trend dependencies over time-series
(2023-11-01)
We improve constraint-based data quality using trend dependency (TD) discovery, extending existing order dependencies (ODs) to allow variations and exceptions. Unlike ODs, TDs capture approximate functional mappings between ...
Categories in control systems software: toward a unified theory of programming & control
(2023-12-01)
Category theory is applied to the design and modeling of control systems application software with emphasis on feedback control. The language of application is iso standard C++17, though the design is abstract and can be ...
