Li, Lin Tzy; Muñoz, Javier A. V.; Almeida, Jurandy; Calumby, Rodrigo T.; Penatti, Otávio A. B.; Dourado, Ícaro C.; Nogueira, Keiller; Mendes, Pedro R.Made available in DSpace on 2018-12-11T16:43:57Z (GMT). No. of bitstreams: 0 Previous issue date: 2015-01-01; In this work, we describe the approach proposed by the RECOD team for the Placing Task, Locale-based sub-task, at MediaEval 2015. Our approach is based on the use of as much evidence as possible (textual, visual, and/or audio descriptors) to automatically assign geographical locations to images and vide...
Automatic identification of epileptic EEG signals through binary magnetic optim...
Pereira, Luís A. M.; Papa, João P. [UNESP]; Coelho, André L. V.; Lima, Clodoaldo A. M.; Pereira, Danillo R. [UNESP]; de Albuquerque, Victor Hugo C.Made available in DSpace on 2018-12-11T17:33:16Z (GMT). No. of bitstreams: 0 Previous issue date: 2017-06-28; Epilepsy is a class of chronic neurological disorders characterized by transient and unexpected electrical disturbances of the brain. The automated analysis of the electroencephalogram (EEG) signal can be instrumental for the proper diagnosis of this mental condition. This work presents a systematic ass...
Fluorinated surfactants in solution: Diffusion coefficients of fluorinated alco...
Martins, Luís F. G.; Pereira, Luís A. M.; Silva, Gonçalo M. C.; Ascenso, José R.; Morgado, Pedro; Prates Ramalho, João P.; Filipe, Eduardo J. M.Intra-diffusion coefficients of three fluorinated alcohols, 2,2,3,3,3-pentafluoropropan-1-ol (PFP), 2,2,3,3,4,4,4-heptafluorobutan-1-ol (HFB) and 2,2,3,3,4,4,5,5,5-nonafluoropentan-1-ol (NFP) in water have been measured by the PFG–NMR spin-echo technique as a function of temperature and composition, focusing on the alcohol dilute region. For comparison, intra-diffusion coefficients of 2,2,2- trifluoroethanol (T...
Diffusion Coefficients of Fluorinated Surfactants in Water:
Pereira, Luís A. M.; Martins, Luís F. G.; Ascenso, José R.; Morgado, Pedro; Ramalho, João P. P.; Filipe, Eduardo J. M.Intradiffusion coefficients of 2,2,2-trifluoroethanol in water have been measured by the pulsed field gradient (PFG)-NMR spin−echo technique as a function of temperature and composition on the dilute alcohol region. The measurements extend the range of compositions already studied in the literature and, for the first time, include the study of the temperature dependence. At the same time, intradiffusion coeffic...
Diffusion coefficients of perfluorinated n-alcohols in water and heavy water: e...
Martins, Luís F. G.; Pereira, Luís A. M.; Ascenso, José R.; Morgado, Pedro; Filipe, Eduardo J. M.Fluorinated surfactants find nowadays many industrial applications due to their enhanced ability to lower surface tension in aqueous solutions [1]. As a result of their extensive use, emissions of fluorinated surfactants became frequent and, because of their persistent character, have been increasingly found in the environment [2]. Both the development of theoretical models to study the environmental fate of th...

Diffusion coefficients of 2,2,2-trifluoroethanol/water mixtures
Pereira, Luís A. M.; Ramalho, João P. P.; Carvalho, Alfredo J. P.; Morgado, Pedro; Filipe, Eduardo J. M.; Martins, Luís F. G.Aqueous mixtures of 2,2,2-trifluoroethanol have received significant attention in the last years because their applications, such as working fluid in Rankine cycle thermal engines or as solvent in studies of protein stability (protein folding). From the fundamental point of view, fluoroalcohols have an amphyphile character, due to the simultaneous presence of a hydrophobic (and alkane-phobic) fluorinated surfac...
