Power-optimal MIMO two-way relay networks
(2018-04-01)
In this dissertation, we study MIMO two-way relay networks consisting of singleantenna users which wish to exchange information with the help of multiple multiantenna relays. The problem we aim to solve is to minimize the ...
Design and development of advanced control techniques for an unmanned ground vehicle
(2018-11-01)
Recent years have seen considerable progress towards the goal of autonomous and unmanned ground vehicles which became essential for conducting military operations. These autonomous vehicles have the capability to operate ...
Modeling, analysis, simulation and real-time hardware in-the-loop implementation of hybrid/electric vehicles’ powertrain
(2019-03-01)
This thesis investigates modeling, analysis and simulation of propulsion system in HEVs/EVs with particular emphasis on transient modeling. To achieve that, a novel complete simulation model on PSIM platform has been ...
Development and investigation of integrated solar systems for hydrogen and methanol production
(2018-04-01)
Implications of climate change, in particular the negative effects of greenhouse gas (GHG) emissions resulting from fossil fuel combustion, as well as the finite nature of fossil fuels necessitate the implementation of ...
Design and development of exclusive modulation techniques for effective power regulation in dual two-level-inverter-fed open-ended winding traction motors
(2019-04-01)
An integral part of an EV propulsion system is the traction drive. The existing two-level inverter drives reportedly has several drawbacks. Multilevel inverter has been proposed as an improvement over the conventional ...
Miniaturization of features in microfluidic paper-based analytical devices for user-friendly testing and diagnosis using small sample volumes
(2019-04-01)
Microfluidic paper-based analytical devices (µPADs) are a promising platform for analytical testing, particularly for medical diagnosis. One of the main advantages of µPADs is the capacity for inexpensive, portable and ...
Pushing the limits of traditional unsupervised learning
(2018-08-01)
Unsupervised learning has important applications in extremely large data settings such as in medical, biological, social, and environmental data. Typically in these settings, copious amounts of data are collected, with the ...
H-Delta: design and applications of a novel 5 degree of freedom parallel robot
(2018-04-01)
This thesis presents a new parallel 5 DOF robot called the H-Delta. The H-
Delta adds 2 degrees of freedom (DOF) to the traditional Delta robot in a novel
way, adding functionality and versatility. Importantly, the rotational ...
Effective modeling of advanced filters and multiplexing networks
(2019-06-01)
Microwave filters and multiplexers are widely used in all types of electronic systems. This research focuses on advanced filters and multiplexers for applications in communication satellites with stringent requirements and ...
Design and optimization of dielectric resonator antenna arrays based on substrate integrated waveguide technology for millimeter-wave applications
(2016-05-01)
With the lower frequency bands heavily crowded, the millimeter wave (MMW) frequency band has attracted a lot of attention, offering a wide range of applications. It also introduces new challenges to the research community. ...
