Effect of Sheep Grazing, Stocking Rates and Dolomitic Limestone Application on ...

Carreira, Emanuel; Serrano, João; Pinto-Gomes, Carlos; Shahidian, Shakib; Paniagua, Luís L.; Pilirito, Alexandre; Lopes Castro, José; Carvalho, Mário

The Montado is a complex agroforestry–pastoral ecosystem due to the interactions between soil–pasture–trees–animals and climate. The typical Montado soil has an acidic pH and manganese toxicity, which affect the pastureʹs productivity and pasture floristic composition (PFC). The PFC, on the other hand, can also be influenced by the type and intensity of grazing, which can lead to significant decreases in the am...


Interoperable decision support system based on multivariate time series for set...

Varela, M.L.R.; Amaral, Gabriela; Pereira, Sofia C.; Machado, Diogo; Falcão, António; Ribeiro, Rita A.; Sousa, Emanuel; Santos, Jorge A.

Nowadays, interoperable decision support systems play a crucial role to improve production activity control in industrial Companies, and enable them to face the growing exigencies imposed by the arising Industry 4.0 era. In this paper an interoperable decision support system based on multivariate time series for setup data processing and visualization is put forward. The proposed system is described, in the con...


Right STS responses to biological motion in infancy - an fNIRS study using poin...

Lisboa, Isabel C.; Miguel, Helga; Sampaio, Adriana; Mouta, Sandra; Santos, Jorge A.; Pereira, Alfredo F.

Biological motion perception-our capacity to perceive the intrinsic motion of humans and animals-has been implicated as a precursor of social development in infancy. In the adult brain, several biological motion neural correlates have been identified; of particular importance, the right posterior superior temporal sulcus (rpSTS).We present a study, conducted with fNIRS, which measured brain activations in infan...


An industry 4.0 oriented tool for supporting dynamic selection of dispatching r...

Ferreirinha, Luis; Baptista, Sara; Pereira, Alfredo F.; Santos, A. S.; Bastos, J.; Madureira, A. M.; Varela, M.L.R.

Production scheduling is an optimizing problem that can contribute strongly to the competitive capacity of companies producing goods and services. A way to promote the survival and the sustainability of the organizations in this upcoming era of Industry 4.0 (I4.0) is the efficient use of the resources. A complete failure to stage tasks properly can easily lead to a waste of time and resources, which could resul...

Ferreirinha, L.; Baptista, S.; Pereira, Alfredo F.; Santos, A. S.; Bastos, J.; Madureira, A. M.; Varela, M.L.R.

Production scheduling is a function that can contribute strongly to the competitive capacity of companies producing goods and services. Failure to stagger tasks properly causes enormous waste of time and resources, with a clear decrease in productivity and high monetary losses. The efficient use of internal resources in organizations becomes a competitive advantage and can thus dictate their survival and sustai...


Decision support visualization approach in textile manufacturing a case study f...

Varela, M.L.R.; Amaral, Gabriela; Pereira, Sofia C.; Machado, Diogo; Falcao, Antonio; Ribeiro, Rita A.; Sousa, Emanuel; Santos, Jorge A.

Decision support visualization tools provide insights for solving problems by displaying data in an interactive, graphical format. Such tools can be effective for supporting decision-makers in finding new opportunities and in measuring decision outcomes. In this study, was used a visualization tool capable of handling multivariate time series for studying a problem of operational control in a textile manufactur...


Visual-vestibular and postural analysis of motion sickness, panic, and acrophobia

Coelho, Carlos M.; Silva, Janete; Pereira, Alfredo F.; Sousa, Emanuel Augusto Freitas; Taephant, Nattasuda; Pisitsungkagarn, Kullaya; Santos, Jorge A.

Trigger motion sickness and can also have a role in some anxiety disorders. We explore a method to detect individual sensitivity to visual-vestibular unusual patterns, which can signal a vulnerability to develop motion sickness and possibly anxiety disorders such as a fear of heights and panic. 65 undergraduate students were recruited for the purposes of this study as voluntary participants (44 females); averag...


An MCDM approach to the selection of novel technologies for innovative in-vehic...

Lisboa, Isabel C.; Vieira, Joana; Mouta, Sandra; Machado, Sara; Ribeiro, Nuno; Silva, Estêvão; Ribeiro, Rita A.; Pereira, Alfredo F.

Driving a car is a complex skill that includes interacting with multiple systems inside the vehicle. Today’s challenge in the automotive industry is to produce innovative In-Vehicle Information Systems (IVIS) that are pleasant to use and satisfy the costumers’ needs while, simultaneously, maintaining the delicate balance of primary task vs. secondary tasks while driving. The authors report a MCDM approach for r...


MUVTIME: a Multivariate time series visualizer for behavioral science

Sousa, Emanuel Augusto Freitas; Malheiro, Tiago Emanuel Quintas; Bicho, Estela; Erlhagen, Wolfram; Santos, Jorge A.; Pereira, Alfredo F.

As behavioral science becomes progressively more data driven, the need is increasing for appropriate tools for visual exploration and analysis of large datasets, often formed by multivariate time series. This paper describes MUVTIME, a multimodal time series visualization tool, developed in Matlab that allows a user to load a time series collection (a multivariate time series dataset) and an associated video. T...


Percutaneous vertebroplasty: a new animal model

Oliveira, Maria Teresa; Potes, Jose; Queiroga, Maria Cristina; Castro, Jose L.; Pereira, Alfredo F.; Rehman, Sarrawat; Dalgarno, Kenneth; Ramos, Antonio

BACKGROUND CONTEXT: Percutaneous vertebroplasty (PVP) is a minimally invasive surgical procedure and is frequently performed in humans who need surgical treatment of vertebral fractures. PVPinvolves cement injection into the vertebral body, thereby providing rapid and significant pain relief. PURPOSE: The testing of novel biomaterials depends on suitable animal models. The aim of this study was to develop a rep...
