Analytical and experimental study of the effect of cutting tool microgeometry on the impact resistance of milling tools
(2021-01-01)
This thesis conducted a two-part investigation into the ability of a milling tool cutting insert to resist the impacts that occur during the milling process, with respect to the cutting edge microgeometry. The first part ...
Development of a light-weight manipulator system for an omni-directional multi-rotor platform
(2020-10-01)
This thesis presents the development of a proof-of-concept physical prototype and control system for a six degree-of-freedom manipulator attached to an omni-directional multi-rotor system known as the OmniRaptor. This ...
Comparison of the force and torque transfer for different cam profiles
(2021-09-01)
This study presents static load and torque distribution measurements in groove cams for sinusoidal and cycloidal cam profiles. In this thesis, two different designs and apparatuses were developed and built for the static ...
Effect of cutting tool microgeometry when milling hardened steels, a finite element simulation and surface integrity analysis
(2021-01-01)
This research work presents a 3D finite element model for the milling of hardened steels. The model was developed using ABAQUS/Explicit software and the Lagrangian approach was utilized. Experimental milling tests were ...

Excavation is the process of moving earth and is considered to be one of the primary projects in the construction industry. The adoption of various cutting-edge technologies for full automation can be a solution to the ...
An energy-efficient periodic resource model for cyber-physical systems By Suzanne Elashri
(2021-08-01)
Cyber-Physical Systems (CPS), especially real-time systems, are subject to time constraints that should be met for the applications to run properly. The schedulability of workloads can be analyzed by determining the supply ...
A bidirectional battery-to-battery energy cycler for battery pack testing and validation
(2020-11-01)
Lithium-ion batteries are becoming popular not only in the Electric Vehicle (EV) market but also in other sectors because of their salient features like high terminal voltage, fast charge/discharge capabilities, and energy ...
Enhancement of bioactive glass biocompatibility by deposition of titanium nanofibres generated by the High Intensity Laser Induced Reverse Transfer Method (HILIRT)
(2020-04-01)
A literature review was done in order to understand the structure and properties of the surface of bioactive glass and how to make this structure biocompatible with the human body. In this research, glass biocompatibility ...
Optimized multi-superframe scheduling for clustered wireless sensor networks
(2020-04-01)
Since the power source for wireless sensor networks (WSN) is mainly from batteries, prolonging network life is an important requirement of the network. Hence, clustering algorithms are employed to decrease the number of ...
