Predicting weighing deviations in the dispatch workflow process: a case study i...
Barros, Júlio Dinis Lopes; Cunha, Francisco; Martins, Cândido; Pedrosa, Paulo; Cortez, PauloThe emergence of the Industry 4.0 concept and the profound digital transformation of the industry plays a crucial role in improving organisations' supply chain (SC) performance, consequently achieving a competitive advantage. The order fulfilment process (OFP) consists of one of the key business processes for the organization SC and represents a core process for the operational logistics flow. The dispatch work...

Nanostructured Ti1-xCux thin films with tailored electrical and morphological a...
Ferreira, Armando José Barros; Pedrosa, Paulo; Martin, Nicolas; Yazdic, Mohammad Arab Pour; Billard, Alan; Lanceros-Méndez, S.; Vaz, F.Inclined, zigzag and spiral Ti1-xCux films were co-sputtered by the Glancing Angle Deposition technique. Two distinct titanium (Ti) and copper (Cu) targets were used and the films were grown with a particle flow incidence angle α of 80°. The thin films had Cu contents ranging from 36 to 76 ± 5 at. %. The effect of increasing Cu incorporation on the electrical anisotropy, as well as the effect of columnar archit...
Properties of CrN thin films deposited in plasma-activated ABS by reactive magn...
Pedrosa, Paulo; Rodrigues, Marco S.; Neto, Miguel A.; Oliveira, Filipe J.; Silva, Rui F.; Borges, Joel; Amaral, Margarida; Ferreira, AntónioIn this work, magnetron sputtered CrNx thin films with nitrogen concentrations ranging from 17 to 30 at.% were deposited on plasma activated ABS. Two sets of thin films were obtained by varying the N2 flow inside the vacuum chamber (series #1) and the deposition time (series #2). The polymer samples were also subjected to plasma treatment in Ar prior to the CrNx thin films' deposition, in order to enhance the a...
Ag:TiN-Coated Polyurethane for Dry Biopotential Electrodes: From Polymer Plasma...
Pedrosa, Paulo; Fiedler, Patrique; Lopes, Cláudia; Alves, Eduardo; Barradas, Nuno P.; Haueisen, Jens; Machado, A. V.; Fonseca, Carlos; Vaz, F.Several plasma treatments using argon, oxygen, and nitrogen are studied in order to increase the interfacial adhesion of the polyurethane/Ag:TiN system to be used as biopotential electrodes. The optimized plasma treatments conditions (100 W, 15 min, regardless of the gas) promote a steep decrease of the water contact angle values. The observed chemical and topographic alterations translate into excellent polyur...
Electrochemical characterization of nanostructured Ag:TiN thin films produced b...
Pedrosa, Paulo; Machado, Diogo; Fiedler, Patrique; Vasconcelos, Beatriz; Alves, Eduardo; Barradas, Nuno P.; Martin, Nicolas; Haueisen, Jens; Vaz, F.Flexible polyurethane substrates were coated with Ag:TiN thin films (N/Ti atomic ratio = 0.7; 10 at.% Ag), with different column inclinations (α = 0°, 40° and 80°) and architectures (columnar, zigzag with 2 and 4 periods), using the Glancing Angle Deposition (GLAD) technique. The coatings were characterized in order to assess the best thin film architecture to suit the bio-potential electrode applications. An a...
Aplicação das concentrações e proporções de nutrientes no diagnóstico da eutrof...
Souza, Juliana Sobreira de; Pedrosa, Paulo; Gatts, Pedro Vianna; Gravina, Geraldo de AmaralEsta revisão aborda a aplicação das concentrações e proporções de nutrientes (nitrogênio e fósforo) no diagnóstico da eutrofização em águas naturais. Foi realizado um breve histórico sobre a eutrofização e considerações sobre os elementos eutrofizantes. O uso das razões no diagnóstico da eutrofização apresenta limitações, uma vez que existem outros parâmetros que impedem a proliferação do fitoplâncton mesmo em ...
