30. Contribuição à análise da capacidade de processamento de trens cargueiros em linhas ferroviárias singelas no Brasil / Contribution to analysis of process capacity of cargo trains on single track railroad line in Brazil
The expessive growth of the railway sector due to the privatization of the operations since 1996, is increasing the participation of this mode in the brazilian transport matrix. However, this growth is obtained mainly from the replacement and increase of the rolling stock and the modernization of the traffic control system, and will soon reach some important

32. Ecolingua: a formal ontology for data in ecology
Ecolingua is an ontology for ecological quantitative data, which has been designed through reuse of a conceptualisation of quantities and their physical dimensions provided by the EngMath family of ontologies. A hierarchy of ecological quantity classes is presented together with their definition axioms in first-order logic. An implementation-level applicatio

35. AnÃlise diagramÃtica para cavidades caÃticas de barreira dupla : equivalÃncia com teoria quÃntica de circuitos
In this work we derive a set of coupled non-linear algebraic equations for the asymptotics of the Poisson kernel distribution, describing the statistical properties of a two-terminal double-barrier chaotic billiar (or ballistic quantum dot). The equations are calculated from a diagrammatic technique [P. W. Brouwer e C. W. Beenakker, J. Math. Phys. 37, 4904 (

36. OPTIMIZATION OF COLUMNS OF REINFORCED CONCRETETALL BUILDINGS / OTIMIZAÇÃO DE PILARES DE EDIFÍCIOS ALTOS DE CONCRETO ARMADO
This work proposes a formulation for the optimum design of columns of reinforced concrete tall buildings. The design variables are the dimensions of the cross-sections and the amount of longitudinal reinforcement in the columns and the concrete characteristic resistance. Aiming at reducing the size of this class of problem, the multilevel optimization techni
