Discrete lot sizing and scheduling on parallel machines: description of a colum...
Duarte, António J.S.T.; Carvalho, J.M.V. Valério deIn this work, we study the discrete lot sizing and scheduling problem (DSLP) in identical parallel resources with (sequence-independent) setup costs and inventory holding costs. We propose a Dantzig-Wolfe decomposition of a known formulation and describe a branch-and-price and column generation procedure to solve the problem to optimality. Preliminary results show that the lower bounds provided by the reformula...

Extracção de dados sobre o formato dos lábios nos sons da Língua Portuguesa
Alexandra Grilo; Pedro Duarte; António Teixeira; Armando PinhoThis paper addresses the problem of automatic extraction of lips format parameters for Portuguese sounds.For that purpose, a system for image acquisition and analysis was developed. The system, based in genetic algorithms and more traditional techniques, calculates several relevant parameters for the lips, using the segmented mouth region. ; Este artigo aborda o problema da extrac&cced...

Duarte, António A. L. SampaioBook edited by Harry Edmar Schulz, André Luiz Andrade Simões and Raquel Jahara Lobosco ; • Short characterization of estuarine systems and the Mondego estuary (Portugal); • Research methods: sampling program description and mathematical integrated modelling (hydroinformatic tool presentation) • Hydrodynamic estuarine modelling, including calibration and validation procedures; • New approach for tidal prism and...
Efficiency removal of copper from potable water using a pine bark
Duarte, António A. L. Sampaio; Machado, João M. D.; Ramísio, Paulo J.All over the world the presence of heavy metals in water supply sources has been raising great concern in terms of public health since many epidemiologic studies confirm the potential carcinogenic effect of these pollutants at concentrations above acceptable standards. Because copper removal is the most frequent option to achieve a safe drinking water, the development of more efficient and sustainable water tre...
Sectoral indices to evaluate the sustainability of wastewater utilities
Granja, Célia; Duarte, António A. L. Sampaio; Ramísio, Paulo J.; Ramos, Rui A. R.; Bentes, IsabelWastewater systems are a structural part of public utilities and as such are vital to the general wellbeing, public health, economic activities and environment protection. These services, with the primary objective of protecting the interests of users, shall be governed by principles of universality of access, continuity and quality of service, efficiency, equity and sustainability of price. The aim of this pap...
Assessment of dissolved zinc removal using new sorbent materials
Duarte, António A. L. Sampaio; Martins, Mário A. C.; Ramísio, Paulo J.The pollution of water supply sources by these metals has a wide variety of severe adverse health effects resulting from a chronic exposure to concentrations above acceptable standards, namely the potential carcinogenic effect of these pollutants confirmed by many epidemiologic studies. Since heavy metals removal from raw water is often the only viable option to obtain safe drinking-water, it is pertinent to gl...
TV WPN : programa de cálculo automático para análise da vulnerabilidade de rede...
Varajão, João; Rodrigues, Tiago; Duarte, António A. L. Sampaio; Varum, Humberto; Pinto, Jorge; Bentes, IsabelA aplicação da teoria da vulnerabilidade a redes de abastecimento de água reais é um procedimento complexo e moroso, tornando imperativo o desenvolvimento de ferramentas informáticas que agilizem e automatizem esse processo. O programa de cálculo automático que está a ser desenvolvido, designado por TV WPN (Theory of Vulnerability of Water Pipe Networks), constitui um importante estímulo à inclusão do estudo da...
Avaliação da eficácia de um sistema de detenção de escorrências urbanas com bas...
Ramísio, Paulo J.; Flores, Mariana; Duarte, António A. L. SampaioA deterioração da qualidade das massas de água tem sido uma problemática bastante preocupante e alarmante nas últimas décadas. Apesar dos grandes investimentos realizados nos sistemas de drenagem pública de águas residuais, continuou a verificar-se a afluência de cargas poluentes aos meios hídricos. Este facto é ainda agravado devido à inexistência de metodologias já estabelecidas para o controlo, tratamento e ...
