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 ...
Effective modeling of advanced filters and multiplexing networks
(2019-06-01)

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. ...
Multimodal series elastic actuator for human-machine interaction with applications in robot-aided rehabilitation
(2019-11-01)
Series elastic actuators (SEAs) are becoming an elemental building block in collaborative robotic systems. They introduce an elastic element between the mechanical drive and the end-effector, making otherwise rigid structures ...
Design and development of a universal gripper mechanism and development of an omni-directional unmanned aerial vehicle for autonomous perching
(2020-04-01)
A novel omni-directional multi-rotor prototype with an attached gripper mechanism named the OmniRaptor is presented with the capability of landing on inclined members in a controlled, stable manner to perform construction ...
Analysis, development, and control of multi-degree-of-freedom passive haptic devices
(2020-08-01)
Stability and transparency are key design requirements in haptic devices. Replacing conventional electric motors with passive actuators such as brakes or dampers can improve both stability and transparency as passive ...
Investigation of three integrated energy systems with desalination, heat storage, thermochemical cycles and heat upgrade
(2020-09-01)
This thesis study proposes three different novel renewable energy-based multigeneration integrated systems with molten salt heat storage and desalination options where copper-chlorine (Cu-Cl) and magnesium-chlorine (Mg-Cl) ...
