Simulation approach for solving production problems reducing total processing time
Pereira, Sibelle; Henriques, Marcelo Filipe Nunes; Varela, M.L.R.; Vicente, José; Freitas, Luis; Machado, JoséThis paper presents an application of computational simulation to a production problem on unrelated parallel machines and dependent setup times, aiming at the reduction of jobs’ total processing time (makespan). The scenarios studied by Rabadi, et al. (2014) were used, along with the SIMIO simulation software, to model and conduct experiments to study the impact of a set of sequencing rules. Based on the comput...
Vision inspection design for systematic production of needle beds: an industria...
Freitas, Luis; Malheiro, M. Teresa; Gonçalves, A. Manuela; Vicente, José; Pereira, Filipe; Morais, Francisco; Bessa, João; Machado, JoséThe increasingly standards of the electronic industry, especially in Printed Circuit Boards, make In-Circuit-Test Machines one of the most important systems on the production lines. With this, the pressure on the In-Circuit-Test Machines production to meet this strict requirements it is getting bigger every day. To react to this pressure it is necessary to update, in a technological point of view, the manufactu...
Conceptual design of a positioning system for systematic production of needle beds
Freitas, Luis; Oliveira, Rui; Malheiro, M. Teresa; Gonçalves, A. Manuela; Vicente, José; Monteiro, Paula; Ribeiro, PedroIn-Circuit-Test Machines are nowadays one of the most important systems on the productions lines in the electronic industry. Printed Circuit Board quality standards have become increasingly higher and all processes involved in its production must be checked and controlled with a high degree of reliability. One particular aspect that clearly did not follow the technological breakthroughs is the manufacturing pro...

Environmental representativity in marine protected area networks over large and...
Stratoudakis, Yorgos; Hilário, Ana; Ribeiro, Cláudia; Abecasis, David; Gonçalves, Emanuel J.; Andrade, Francisco; Carreira, Gilberto P.Converting assemblages of marine protected areas (MPAs) into functional MPA networks requires political will, multidisciplinary information, coordinated action and time. We developed a new framework to assist planning environmental representativity in a network across the marine space of Portugal, responding to a political commitment to protect 14% of its area by 2020. An aggregate conservation value was estima...
From sea monsters to charismatic megafauna: changes in perception and use of la...
Mazzoldi, Carlotta; Bearzi, Giovanni; Brito, Cristina; Carvalho, Inês; Desiderà, Elena; Endrizzi, Lara; Freitas, Luis; Giacomello, Eva; Giovos, IoannisMarine megafauna has always elicited contrasting feelings. In the past, large marine animals were often depicted as fantastic mythological creatures and dangerous monsters, while also arousing human curiosity. Marine megafauna has been a valuable resource to exploit, leading to the collapse of populations and local extinctions. In addition, some species have been perceived as competitors of fishers for marine r...

Implementing Success Management in an IT project
Varajão, João; Magalhães, Luís Gonzaga Mendes; Freitas, Luis; Ribeiro, Pedro Abreu; Ramos, João Ricardo MartinsGiven the high importance and complexity of the evaluation of Information Technology (IT) projects, it is essential that companies define and implement systematic processes for managing success aiming to improve project management and deliverables performance. This article presents the first stage of the implementation of a success management process in an IT project of a large multi-national company. Prelimina...
A Problemática da Poluição da Água: a visão de alunos do 1.º Ciclo do ensino bá...
Linhares, Elisabete; Cavadas, Bento; Freitas, LuisA sociedade globalizada da qual fazemos parte fomenta um consumo que vai para além das verdadeiras necessidades humanas. Relacionado com este consumo está o aumento da exploração dos recursos naturais e a elevada produção de resíduos que provocam grandes prejuízos ambientais. Neste contexto, a educação ambiental cria oportunidades para o desenvolvimento de competências e capacidades de compreensão crítica do mu...

Subtil, João; Jordao, Luisa; Freitas, Luis; Santos, A.; Araujo, J.; Duarte, Aida; Rodrigues, João Carlos; Reis, Lucia; Nogueira, IsabelObjectivo: Avaliar a relação entre a formação de biofilmes na amígdala faríngea e a incidência de infecções respiratórias altas recorrentes na idade pediátrica. Métodos: Colheita de amostras da superfície do cavum faríngeo e meato médio por zaragatoas e biópsia da profundidade da amígdala faríngea de 70 indivíduos, analisados para identificar população bacteriana por métodos padronizados. A identificação foi ob...
