Lactate threshold during resistance exercise in elderly
Souza, Markus Vinicius Campos; Pereira, Guilherme Borges; Bertucci, Danilo Rodrigues; Magosso, Rodrigo Ferro; Baldissera, VilmarThe presence of anaerobic threshold (AT) in resistance exercise has been studied in recent years. The aim of this study was to identify and to compare the AT in elderly population during leg press (LP) and bench press (BP). Fourteen elderly men (68.9 ± 4.0 years, 170.5 ± 0.05 cm e 76.1 ± 7.8 kg) performed two maximal incremental tests based on percentages of one repetition maximum (1RM) for the determination of...
Comparação de dois algoritmos genéticos aplicados ao TOP
Oliveira, José A.; Ferreira, João; Figueiredo, Manuel; Dias, Luís M. S.; Pereira, GuilhermeA recolha seletiva de resíduos sólidos urbanos para reciclagem é um processo dispendioso, especialmente quando realizado em grande escala. Um problema importante neste processo reside na gestão de uma frota, uma vez que atualmente as estratégias utilizadas geralmente têm baixa eficiência. O processo de recolha seletiva de resíduos sólidos urbanos pode ser modelado como um problema de encaminhamento de veículos,...

Peito, Francisco; Pereira, Guilherme; Leitão, Armando; Dias, Luís M. S.; Oliveira, José A.This paper is concerned with the use of simulation as a decision support tool in maintenance systems, specifically in MFS (Maintenance Float Systems). For this purpose and due to its high complexity, in this paper the authors explore and present a way to develop a flexible MFS model, for any number of machines in the workstation, spare machines and maintenance crews, using Arena simulation language. Also in thi...
An optimisation model for the warehouse design and planning problem
Geraldes, Carla A. S.; Carvalho, Sameiro; Pereira, GuilhermeIn spite of the importance of warehouses in the field of the supply chain management, there is not a single decision model that integrates all the decisions that concerns the warehouse design and planning problem. In this paper we discuss a mathematical programming model aiming to support some warehouse management and inventory decisions. Our aim is to address the complexity related to the modeling of the wareh...
An optimisation model for the warehouse design and product assignment and alloc...
Geraldes, Carla A. S.; Carvalho, Sameiro; Pereira, GuilhermeWarehouse design and planning is a great challenge in the field of Supply Chain Management. In this paper we discuss an optimisation model aiming to support some warehouse management decisions. In particular a mixed-integer programming model (MILP) is presented to determine product assignment and allocation to the functional areas, as well as the size of each area. Our aim is to capture the trade-offs among the...

A morosidade da justiça em Portugal : a percepção dos juízes dos Tribunais de 2...
Pereira, Guilherme Alberto MendesDissertação de mestrado em Administração Pública (área de especialização em Gestão Pública) ; O sistema judicial é hoje um factor considerado estratégico para a economia de um país. O tema da morosidade da justiça não é novo, mas tem assumido novos contornos nos últimos tempos, com especial destaque para os problemas relacionados com a morosidade da justiça, cujas implicações negativas para o funcionamento do ...
Clínica de cães com cardiomiopatia dilatada idiopática, tratados ou não com car...
Leomil Neto,Moacir; Balieiro,Júlio César Carvalho; Pereira,Elaine Cristina Soares; Pereira,Guilherme Gonçalves; Oliveira,Valéria Marinho deO tratamento convencionalmente preconizado para cães acometidos pela CMD consiste na prescrição de vasodilatadores, agentes inotrópicos positivos (digitálico), diuréticos, dieta hipossódica e, quando necessário, antiarrítmicos. O carvedilol é um β-bloqueador de 3ª geração, não seletivo, que bloqueia igualmente e competitivamente os receptores (β1, β2 e α1). Produz uma evidente vasodilatação ...
Modeling and simulating a textile production system
Oliveira, Sérgio; Oliveira, José A.; Dias, Luís M. S.; Pereira, GuilhermeThis paper presents a study for a production scheduling problem in a textile company, specifically in the weaving preparation area. Basically, the processing orders can be considered as sequential working steps trough three operations (charging - weaving - discharging), and the goal is to minimize time variation and to avoid delays. The machine utilization should be as higher as possible due to short delivering...
A business intelligence solution for public transportation sector
Sampaio, Paulo; Pereira, Guilherme; Carvalho, Maria Sameiro; Telhada, José; Paisana, António; Paixão, Paulo; Fonseca, AlbertinoSmart companies in the 21st century use business intelligence solutions to gain a clearer picture of their internal operations, customers, supply chain and financial performance. In short, they are using business intelligence solutions to become intelligent about the way they do business.. Our paper reflects the result of a project that we conducted in Portugal related to the development of a business intellige...
