In the last few years, the collective analysis in football teams has been focused on their complex reality. This study aimed to propose 4 collective metrics based on the spatio-temporal relationship, trying to identify differences between the moments with and without ball possession. A U14 7-a-side football match was analysed. Significant differences were found between the moments with and without ball possessi...
The optimization of the feeding trajectories in fed-batch fermentation processes is a complex problem that has gained attention given its significant economical impact. A number of bio-inspired algorithms have approached this task with considerable success, but systematic and statistically significant comparisons of the different alternatives are still lacking. In this paper, the performance of different metahe...

The microalga Nannochloropsis sp. was used in this study, in a biorefinery context, as biomass feedstock for the production of fatty acids for biodiesel, biohydrogen and high added-value compounds. The microalgal biomass, which has a high lipid and pigment content (mainly carotenoids), was submitted to supercritical CO2 extraction. The temperature, pressure and solvent flow-rate were evaluated to check their ef...
Supercritical fluid extraction of all-E-lycopene from tomato industrial wastes (mixture of skins and seeds) was carried out in a semi-continuous flow apparatus using ethane as supercritical solvent. The effect of pressure, temperature, feed particle size, solvent superficial velocity and matrix initial composition was evaluated. Moreover, the yield of the extraction was compared with that obtained with other su...
Tese de mestrado integrado em Engenharia da Energia e do Ambiente, apresentada à Universidade de Lisboa, através da Faculdade de Ciências, 2011 ; Com o constante aumento das necessidades e exigências do conforto térmico em ambiente construído, é imperativo que as facturas energéticas, económicas e ambientais que destas discorrem sejam minimizadas ao máximo, para que um equilíbrio harmonioso com o meio que nos ...
Tese de mestrado, Biologia (Biologia Molecular Humana), 2009, Universidade de Lisboa, Faculdade de Ciências ; Mesenchymal Stem Cells (MSC) hold a great promise for application in several therapies due to their unique biological characteristics. MSC can be easily isolated from bone marrow (BM) based on its adherence to plastic, and can be expanded in culture while maintaining the capacity to differentiate into ...
Based on criteria of mathematical simplicity and consistency with empirical market data, a stochastic volatility model is constructed, the volatility process being driven by fractional noise. Price return statistics and asymptotic behavior are derived from the model and compared with data. Deviations from Black-Scholes and a new option pricing formula are also obtained.
