Metodologias Integradas de CAD, CAE e PDM para o Projeto de um Veículo de Competição
— 2020
Since the genesis of the motor vehicle in the 19th century, automobile competition has been one of the key tools for testing and developing new technologies, before they were mass produced and commercialized. In this context, the technologies to be developed today are increasingly linked to the envi…

Unsteady flow and heat transfer through triply periodic minimal surfaces
— 2020
New advancements in manufacturing methods such as 3D printing, allow the construction and projection of novel metallic foams suitable for the improvement of heat exchangers performance that outperform those typically used. The Triply Periodic Minimal Surfaces (TPMS) are great candidates for the foam…

When implementing survival models for two or more times-to-event separately, some information may be getting mislaid, especially if these are correlated. For that reason, here we focus on jointly modelling two times-to-event: overall survival time (OST) and disease free time (DFT), using copula func…

The continuous search for more efficient heat exchangers - in particular, those with liquid coolant - promotes, depending on the working conditions, the occurrence of boiling. Consequently, the performance, integrity of the equipment components and coolant can be compromised. The present work was h…

Numerical investigation of the influence of the fuel on the performance of a laboratory combustor.
— 2020
In this work, numerical simulations were performed to study the fuel flexibility of a small-scale combustor operating in the flameless combustion mode. The combustor geometrical characteristics and the operating conditions, such as thermal power and equivalence ratio (φ), were kept constant for all …

Road lighting efficiency improvement through data processing and automated computation
— 2020
Road lighting design requires extraction of crucial parameters i.e. lighting situations from the data (both road and lighting infrastructure) regarding the area intended for the retrofit. As the commercially available software is not capable of batch processing geospatial data, this process is curre…

Technical-economic Studies of Bio-Waste Valorisation for Local Multi-Energy System
— 2020
Globally, substantial volumes of bio-waste are generated every day, causing severe environmental concerns, occupying soil, and demanding financial support for its management. An ingenious way of handling this bio-waste challenge is the expansion of modern and original methods focused on the alterati…

Automatic classification of LCA data
— 2020
Life Cycle Assessment (LCA) is a useful tool for environment impact assessment and decision making in energy systems, meanwhile it’s also complicated as it requires detailed information, time and computing resources. Many studies have been conducted to make LCA simpler in the categories of impact as…
