Developing a system for sectorization: An overview
Öztürk, E. L.; Sousa, F. S. de.; Lima, M. M.; Rocha, P. F.; Rodrigues, A. M.; Ferreira, J. S.; Nunes, A. C.; Lopes, I. C.; Oliveira, C. T.Sectorization is the partition of a set or region into smaller parts, taking into account certain objectives. Sectorization problems appear in real-life situations, such as school or health districting, logistic planning, maintenance operations or transportation. The diversity of applications, the complexity of the problems and the difficulty in finding good solutions warrant sectorization as a relevant researc...
A resectorization of fire brigades in the north of Portugal
Lima, M. M.; Sousa, F.; Öztürk, E. G.; Rocha, P. F.; Rodrigues, A. M.; Ferreira, J. S.; Nunes, A. C.; Lopes, I. C.; Oliveira, C. T.Sectorization consists of grouping the basic units of a large territory to deal with a complex problem involving different criteria. Resectorization rearranges a current sectorization avoiding substantial changes, given a set of conditions. The paper considers the case of the distribution of geographic areas of fire brigades in the north of Portugal so that they can protect and rescue the population surrounding...
Accelerated life testing of frozen green beans (Phaseolus vulgaris, L.) quality...
Martins, R. C.; Lopes, I. C.; Silva, C. L. M.This study uses the information derived from a computational research for the design of accelerated life testing (ALT) to implement experimentally the step stress methodology for the quantification of frozen green beans (Phaseolus vulgaris, L.) colour and starch degradation kinetics. Colour loss and starch degradation were successfully modelled, respectively, by a first-order reversible and apparent first-order...
