Towards an ontological framework for environmental survey hazard analysis of autonomous systems (2021)
Presentation / Conference Contribution

This paper presents current progress in the development of Environmental Survey Hazard Analysis (ESHA), a method of preliminary hazard identification aimed at autonomous system application problems. In addition to performing their design mission, aut... Read More about Towards an ontological framework for environmental survey hazard analysis of autonomous systems.

Investigating the dynamic compression response of elastomeric, additively manufactured fluid-filled structures via experimental and finite element analyses (2021)
Journal Article

This study evaluates a fluid-filled, closed-cell lattice as a novel route to reducing peak acceleration in impact environments. A conical structure was designed and built using fused filament fabrication. One structure was manufactured hollow (100% a...

Application of the direct power control strategy in a shunt active filter by exploiting the solar photovoltaic energy as a continuous source (2020)
Journal Article

In order to follow the standard recommendations of the electrical energy quality (IEEE519) on the distribution network, the active filter have responded to these recommendations, which require that the Total Harmonic Distortion (THD) must be less tha...

Laser powder bed fusion of WC-reinforced Hastelloy-X composite: Microstructure and mechanical properties (2020)
Journal Article

Nickel-based superalloys such as Hastelloy X (HX) are widely used in gas turbine engines for their exceptional oxidation resistance and high-temperature strength. The addition of ceramic reinforcement further enhances these superalloys’ mechanical pe...

The effect of heat treatment of AlSi10Mg on the energy absorption performance of surface-based structures (2020)
Presentation / Conference Contribution

Additive Manufacturing of cellular lattice structures offers opportunities to fine-tune the mechanical response by altering geometric variables. It is known that heat treatment cycles provide an effective way of altering mechanical properties while r...

Development of design criteria for novel 3D-printed quadric-surfaced sludge digesters for wastewater infrastructure (2020)
Thesis

The quadric-surfaced sludge digester (QSD), also known as the egg-shaped sludge digester, has proven its advantages over traditional cylindrical digesters recently. A reduction in operational cost is the dominant factor. Its shell can be described as...
