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 ...
Design, analysis, and control of switched supercapacitor banks for e-transportation electric energy storage systems
(2020-07-01)
The hybridization of supercapacitors (SCs) with batteries in electric vehicles (EVs) improves the battery life, acceleration, and driving range. However, the efficiency of the power interface that unites the batteries and ...
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 ...
Development of waste management systems: applications of Durham Region
(2021-08-01)
This thesis aims to reduce environmental impacts and increase overall efficiencies of domestic waste management systems by proposing case studies for Durham Region. Case study 1 integrates an anaerobic digestion facility ...
Constant-temperature constant-voltage charging method for lithium-ion battery technology
(2020-09-01)
Lithium-ion batteries are the Electrical Vehicles' (EVs) best choice of Energy Storage Systems (ESS) on account of their energy density, power density, and life cycle. In order for the EVs to compete with conventional ...
Yield estimation and smart harvesting for precision agriculture using deep learning
(2021-08-01)
Precision agriculture is one of the fastest growing fields in recent years. In this thesis, we introduce a framework that provides farmers with a yield estimation from videos of crops and provides guided assistance for ...
An integrated wind-powered energy system for residential applications in cold regions
(2021-09-01)
This thesis proposed an integrated direct wind-powered energy system that can provide drinking water, domestic hot water, space heating as well as electricity for residential applications of a remote community in a cold ...
Fast algorithm for joint unicast and multicast beamforming in large-scale systems
(2021-09-01)
We consider a joint unicast and multi-group multicast beamforming problem for massive multiple-input multiple-output (MIMO) system with a large number of unicast users. We propose an alternating direction method of multipliers ...
