Development of a functional prototype for recovery of recycled expanded polysty...
Leite, Pedro; Correia, Carlos M.; Araújo, Raquel; Tinoco, João; Gama, Nuno; Ferreira, Paula; Gonçalves, Idalina; Neto, Victor; Zhiltsova, TatianaExpanded polystyrene (EPS) is composed of 98% air and 2% polystyrene (PS). EPS parts are made up of PS beads that contain a blowing agent, typically pentane, entrapped into their interior, allowing them to expand and form a honeycomb-similar cellular structure. The expandable PS beads allow for efficient storage and transportation while also providing control over density in separate steps (pre-expansion and mo...
Therapeutic inertia in type 2 diabetes mellitus: perception of general practiti...
Rosa, Sara; Reis, Joana; Ferreira, Sara; Alves, Ricardo; Silva, Ricardo; Leite, Pedro; Faria, Mariana; Ribeiro, AnabelaIntroduction: Our study aimed at identifying barriers to the initiation of insulin therapy and its associated sociodemographic and labor factors. Material and Methods: This cross-sectional study was carried out through a survey applied to 146 general practitioners working in Almada and Seixal primary health care centers, between October and December 2019, assessing their agreement on 30 barriers using a 5-point...
Efetividade da vacina contra a COVID-19: implementação de estudo de coorte em p...
Gaio, Vânia; Silva, Adriana; Amaral, Palmira; Viana, João Faro; Antunes, Isabel; Gonçalves, João; Gonçalves, Lígia A.; Leite, Pedro; Machado, AusendaNum contexto de pandemia, os profissionais de saúde dos hospitais são considerados um grupo de elevado risco para a infeção por SARS-CoV-2 sendo um grupo prioritário para a vacinação. Apesar dos bons resultados da eficácia das vacinas nos ensaios clínicos, são muitos os fatores que podem influenciar a sua eficácia no mundo real (efetividade). Com base num desenho de estudo de coorte prospetivo, desenvolveu-se u...
The Density Effect in (W-S-W) Wood Connections with Internal Steel Plate and Pa...
Silva, Lino; Leite, Pedro; Fonseca, Elza M MThe main objective of this work is to understand the fire behaviour of unprotected wood-to-wood connections with internal steel plate (W-S-W) in comparison with connections using passive protection with gypsum plasterboard. Passive fire protection uses systems that help prevent the spread of fire. Analytical methodologies according Eurocode 5 part 1-1 were used to the designed connections in different wood dens...
The Fire Resistance of (W-W-W) Wood-To-Wood Connections Protected with Differen...
Leite, Pedro; Silva, Lino; Fonseca, Elza M MThe main objective of this work is to verify the fire resistance of unprotected (W-W-W) wood-towood connections and compare the results with protected connections using gypsum plasterboard. According Eurocode 5, part 1-2 the connections could be protected by the addition of wood panelling, wood-based panels or gypsum plasterboard type A, H or F. To obtain conclusions according the application of different type ...
Mimicking human movement with robots: control of an anthropomorphic robotic arm...
Oliveira, Ricardo; Resende, Ricardo; Soares, Filomena; Calado, Alexandre; Leite, PedroThe present paper proposes, as an educational activity, the design of a system that allows the control of a robotic manipulator by using a sensory glove and an arm sleeve. The robotic manipulator features a robotic arm and hand, with a total of 10 degrees of freedom, using ten servo motors as actuators. On the other hand, the controller component features six flex sensors and two Inertial Measurement Units (IMU...
Design of a framework to promote physical activity for the elderly
Calado, Alexandre; Leite, Pedro; Soares, Filomena; Novais, Paulo; Arezes, P.Physical inactivity is estimated to be one of the leading risk factors for global mortality and it is associated with several illnesses, such as type 2 diabetes, cardiovascular diseases and various types of cancers. To tackle this issue and promote physical activity amongst the elderly, a system that computes automatically, in real-time, the score of a Boccia game was developed. The objective of this paper is t...
Developing a framework for promoting physical activity in a Boccia game scenario
Silva, Vinicius Corrêa Alves; Ramos, João Ricardo Martins; Leite, Pedro; Soares, Filomena; Novais, Paulo; Arezes, P.; Sousa, Filipe; Figueira, CarinaThe traditional keyboard has been replaced by tactile screens or other types of implicit interfaces. An example of such interface is the Microsoft Kinect system, which makes use of a depth sensing system to enable the user-machine interaction. Allied to the physical activity, this hardware may be used to track and monitor the user when he/she is exercising, but also to diminish a sedentary lifestyle. In this pa...
Boccia court analysis for promoting elderly physical activity
Calado, Alexandre; Leite, Pedro; Soares, Filomena; Novais, Paulo; Arezes, P.Physical inactivity is one of the leading risk factors for global mortality. Older adults, in particular, are more probable to suffer the consequences of physical inactivity, since it is one of the most sedentary age groups. On the other hand, engaging physical activity can have various benefits for the prevention of several diseases and functional loss prevention, therefore, it is critical to encourage its reg...
Boccia court analisys for real-time scoring
Leite, Pedro; Calado, Alexandre; Soares, FilomenaThis paper aims to develop a tool to increase the engagement and commitment of the elderly population in the Boccia game. This tool is based on the implementation of a real-time computer vision algorithm that analyses the Boccia court field and displays the score in a graphical user interface. In Portugal, physical inactivity is associated with 14% of deaths per year, higher percentage than the world average, w...
