At highway speeds, up to 65 % of the total energy used by large trucks is for overcoming aerodynamic drag. The underbody region of a tractor-trailer is responsible for up to 30 % of the aerodynamic drag on tractor-trailers, ...

Dimethyl-ether (DME) is considered to be one of the most promising, renewable alternative fuels. This thesis studies, develops, analyzes and assesses the performance of three dimethyl-ether production integrated systems, ...

Stirling engines have a high potential to produce renewable energy due to their ability to use a wide range of sustainable heat sources and their high theoretical efficiencies. They have not yet achieved widespread use and ...

This thesis presents the design and testing of a scale proof-of-concept prototype end-effector system for autonomous shotcrete application and radiation surveying in underground uranium mining environments. The prototype ...

Despite many weaknesses, passwords are still mainly used, and will continue to be used in the near future, for the user authentication process. Passwords remain one of the important pillars of the protection structure even ...

Acoustic resonance is a phenomenon which is known to have severe repercussions in a variety of industrial systems. Acoustic resonance can cause high levels of vibrations leading to damage or premature failure of critical ...

A legacy electric power distribution system is characterized by a unidirectional power flow from centralized power plants to customers. The role of these customers has been known for many years as power consumers and not ...

Hydrogen is a promising alternative as an energy carrier (and carbon-free fuel) to meet the global power demand. Hydrogen production systems can efficiently harvest energy from renewable sources. Even though photo-electrochemical ...
