RESUMO Neste trabalho foi desenvolvido um modelo multiobjetivo para otimização da operação de sistemas distribuição água (SDAs), visando alcançar a eficiência hidroenergética considerando três objetivos: redução das perdas por vazamento; do custo energia elétrica no bombeamento; e maximização confiabilidade sistema. O concebido pela implementação uma rotina computacional entre os algoritmos gen...

BACKGROUND & OBJECTIVES Group C and group G streptococci (together GCGS) are often regarded as commensal bacteria and their role in streptococcal disease burden is under-recognized. While reports of recovery of GCGS from normally sterile body sites are increasing, their resistance to macrolides, fluoroquinolone further warrants all invasive β haemolytic streptococci to be identified to the spec...

Urban block-scale sponge system design needs address how to specify the optimal approach combine number of areas and types facilities for diverse land conditions objectives, while ensuring performance economic efficiency. With gradual application multi-objective optimization algorithms in cities, combinatorial problem solving based on is more accurate efficient than traditional methods designer...

In a previous paper a novel Generalized Multiobjective Multitree model (GMM-model) was proposed. This model considers for the first time multitree-multicast load balancing with splitting in a multiobjective context, whose mathematical solution is a whole Pareto optimal set that can include several results than it has been possible to find in the publications surveyed. To solve the GMM-model, in...

There are several initiatives for quality control in the supply of software and related services. In general, the most known and applied are the result of initiatives on the part of the customer: well defined acquisition processes, supplier selection based on certification or maturity assessment, contract monitoring. All these initiatives are aimed either to give confidence about the supplier c...

purposes but conservationists fear it may disturb the birds. They are keen to ramp up their efforts but losing 65 per cent of this year’s chicks has been a major blow, said Ana Isabel Fagundes of Portugal’s national ornithological society, SPEA. Conservationists have reinforced the nests that contain surviving birds to help protect them from the anticipated increased soil erosion as a result of...
