Development of an integrated tracking control algorithm and a test platform for autonomous excavation
(2020-03-01)
Since construction is part of the industrial sector where a large amount of labor is required and workers operate under harsh environmental conditions, the transformation from manual to autonomous operation in modern ...
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) ...
Combustion and emission characteristics of ammonia blended fuels in a spark-ignited engine
(2020-06-01)
Climate change and fossil fuel depletion has brought attention to the need for alternative fuels. Ammonia shows great potential as an alternative fuel because it is carbon-free and can be produced renewably. In this study ...
Effect of diameter ratios on the flow-sound interaction of the straight circular finned cylinders
(2020-01-01)
Finned tubes that are widely used in heat exchangers could be susceptible to the flow-excited acoustic resonance that generates intense pressure fluctuations, which may lead to premature fatigue failure of the tubes. This ...
Design and evaluation of solar and geothermal energy systems integrated with Cu-Cl cycle
(2020-09-01)
This thesis study proposes solar and geothermal based three multigeneration systems. System 1 consists of a bifacial photovoltaic (BiPV) plant, multi-effect distillation (MED) desalination unit and, proton exchange membrane ...
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 ...
Proposing effective coordinate search methods for solving large-scale expensive black-box optimization problems
(2020-08-01)
In engineering and science, optimization plays a vital role in many real-world applications. In this work, several novel optimization algorithms based on Coordinate Search (CS) algorithm are proposed. CS is a gradient-free ...
Design, development and experimental validation of a lab-scale system for rapid rotational molding of functionally graded integral-skin cellular polyethylene composites
(2020-03-01)
An existing lab-scale experimental setup system, originally developed for a patented Rapid Rotational Foam Molding (RRFM) process, was re-designed, built, and its functionality was successfully experimentally verified. The ...
Development of eco-driving control system for connected and automated hybrid electric vehicles
(2020-04-01)
Hybrid electric vehicles (HEVs) were designed as a potential solution to the ever-increasing global problems of the energy crisis and global warming through flexibly utilizing both fuel and electrical energy. Besides, the ...
