Assessment of Geometrical Features of Internal Flaws with Artificial Neural Network Optimized by a Thermodynamic Equilibrium Algorithm
(University of Waterloo, 2020-10-21)In nondestructive testing (NDT), geometrical features of a flaw embedded inside the material such as its location, length, and orientation angle are critical factors to assess the severity of the flaw and make post-manufacturing ... -
Design of Ultrasonic Processing Device for Aluminum Surfaces
(University of Waterloo, 2018-01-19)The work in this thesis examines the design possibility of a device capable of harnessing ultrasonic oscillations through resonance such that it can be applied onto an aluminum surface to produce a compressive residual ... -
Development of a Feasible Elastography Framework for Portable Ultrasound
(University of Waterloo, 2017-10-06)Portable wireless ultrasound is emerging as a new ultrasound device due to the advantages such as small size, lightweight and affordable price. Its high portability allows practitioners to make diagnostic and therapeutic ... -
Development of Ultrasonic Devices for Non-destructive Testing: Ultrasonic Vibro-tactile Sensor and FPGA-Based Research Platform
(University of Waterloo, 2020-04-29)This thesis is focused on the development of ultrasonic devices for industrial non-destructive testing (NDT). Ultrasound is generated from mechanical vibrations and then propagates through the medium. Ultrasonic devices ... -
Enhancing Focused Ultrasound Therapy Using Nanoscale Agents
(University of Waterloo, 2020-05-05)Focused ultrasound therapy, also known as high intensity focused ultrasound (HIFU), is a new energy-based method that uses ultrasonic energy to treat a range of health disorders and tumors. Despite the great potential for ... -
FPGA Based Ultrasonic Non-Destructive Testing
(University of Waterloo, 2022-05-05)In this research, a prototype of an ultrasonic testing device was developed based on a field-programmable gate array for ultrasonic testing. Ultrasound is a mechanical wave that is generated by a vibrating object and ...
