Powered smart textile-based exoskeleton for human support movement
Ferreira, C.; Fertuzinhos, A.; Silva, R.; Ramalho, M.; Vale, B.; Silva, J.; Costa, L.; Oliveira, C.; Ramôa, A.; Aguiar, F.; Pilastri, A.; Matta, A.Industrial environments require people’s physical efforts related to excessive force, poor posture, and repetitive tasks that increase the risk of developing musculoskeletal diseases. Due to the high prevalence of postural complaints and consequent global health burdens, a significant demand has been conducted to build and implement powered lower and upper limb devices for human enhancement, considering the wor...
Ageing profiling of craft beers: a sensorial and chemical overview
Lemos, M.; Coelho, Eduardo João Louro; Macieira, F.; Pereira, F. B.; Oliveira, J. M.; Domingues, LucíliaOne of the main differences between craft and commercial beers is the presence of active yeast in the bottle, which can have high impact on beer stability during shelflife. For this reason, sensory and chemical beer profiling during storage is of upmost importance when focusing quality control. This study investigated the changes that occur during the storage/ageing of four different craft beers and two commerc...
A new genetic algorithm to be used in the direct fit of potential energy curves...

New insights on lithium-cation microsolvation by solvents forming hydrogen-bond...
Llanio-Trujillo, J. L.; Marques, J. M. C.; Pereira, F. B.This investigation uses a recent methodology, essentially based on our evolutionary algorithm (EA) to get new insights about the energetics and structure of the first solvation shells of lithium ion in polar solvents that form important hydrogen bonds. We employed the EA to search for the low-energy structures of the Li+(H2O)n and Li+(CH3OH)n clusters (with n ⩽ 20) as modeled by commonly used rigid nonpolarizab...
On the Use of Different Potential Energy Functions in Rare-Gas Cluster Optimiza...
Marques, J. M. C.; Pereira, F. B.; Leitão, T.We study the effect of the potential energy function on the global minimum structures of argon clusters arising in the optimization performed by genetic algorithms (GAs). We propose a robust and efficient GA which allows for the calculation of all of the putative global minima of ArN (N = 3−78) clusters modeled with four different potentials. Both energetic and structural properties of such minima are compared ...
