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 an autonomous scaled electric combat vehicle
(2019-04-01)
Current literature pertaining to multi-steerable mobile robots and the progression of military vehicles in the past few decades suggest a lack of effort in pursuing advanced technologies in this joint area. As a result, a ...
Robust controller design for active trailer steering systems of articulated vehicles using multi-objective optimization
(2019-08-01)
This thesis presents and evaluates an approach to the robust controller design for active trailer steering (ATS) systems to increase the safety of articulated vehicles. By applying a multi-objective evolutionary algorithm ...
Integrated topology optimization design and process planning for additive manufacturing
(2019-08-01)
Industry 4.0 demands that the systems and processes in today’s product design and manufacturing not just be automated, but to be robust and containing many feedback mechanisms which enables it to be self-correcting. The ...
Simulation of microgrid system and low-cost wireless communication network
(2019-08-01)
The MATLAB/SIMULINK model of a microgrid system is presented in this thesis. The microgrid consists of a converter-fed distributed generator photovoltaic array with maximum power point tracking, a converter-fed battery ...
Optimal structure and efficient algorithm for max-min fair multi-group multicast beamforming
(2019-09-01)
In this thesis, we consider the max-min fair (MMF) multi-group multicast beamforming design to maximize the minimum signal-to-interference-plus-noise ratio (SINR) subject to transmit power limit. We obtain the optimal ...
Design and analysis of active aerodynamic control systems for increasing the safety of high-speed road vehicles
(2019-07-01)
The lateral stability and the safety of road vehicles is dependent on the vehicle design and operating conditions. Under operating conditions such as slippery roads, high lateral acceleration and tight cornering, the forces ...
Investigation of drying conditions for dental practice loads
(2019-04-01)
This thesis investigates different drying techniques for dental practice loads experimentally and numerically. Several experiments are carried out by changing both top and bottom wall temperatures while changing the ranges ...
Investigation of a hydrogen production process through aluminum and water chemical reaction
(2019-12-01)
This thesis reported a novel hydrogen production experimental set up, which utilized the chemical reaction between aluminum and water to produce hydrogen. The constructed experimental setup had an aluminum powder spraying ...
Analysis and optimization of fuel cell based integrated powering systems for clean rail applications
(2019-08-01)
In this thesis, proposals of novel integrated fuel cell powering systems for cleaner railway applications are presented and analyzed thermodynamically. Both energy and exergy analyses are conducted on these systems for ...
