37. Airline crew scheduling in the Brazilian context. / Programação de tripulantes de aeronaves no contexto brasileiro.
This master of science research treats the Crew Scheduling Problem (CSP), as part of the airlines operational planning. The main aim of the CSP is to assign a set of tasks to crew members, considering the labor regulations, safety rules and policies of companies, such that the crew cost is minimal. The CSP is divided into two subproblems, solved sequentially

38. BALANCED SCORECARD AS A SYSTEMATIC MANAGEMENT IN SEARCH OF CONTINUOUS IMPROVEMENT OF ORGANIZATIONAL QUALITY / BALANCED SCORECARD COMO SISTEMÁTICA DE GESTÃO EM BUSCA DA MELHORIA CONTÍNUA DA QUALIDADE ORGANIZACIONAL
The managerial decisions, inside of the context of global economy have been strongly marked by the imminent need of search and application of new techniques and tools of administrative administration. In that sense, Balanced Scorecard - BSC initially created as an evaluation system and organizational performance, and later used as a methodology of strategic

39. A separação de poderes e o processo de institucionalização das agências reguladoras de telecomunicações nos EUA e no Brasil
This dissertation analyses the way in which separation of powers and checks and balances have influenced the process of institutionalization of telecommunication regulation in the USA and in Brazil, leading to the creation of the American Federal Communications Commission (FCC) and the Brazilian Agência Nacional de Telecomunicações (Anatel). As the experi

40. Problema de reagrupamento capacitado / Redistricting capacitated problem
The aim of this dissertation is to develop an eficient methodology to solve the multicriteria redistricting capacitated problem (PACM), in which objects with associated weights are given, which must be partitioned into groups with limited capacity. In this work, the PACM is inserted in to a reassignment problem of urban clusters of clients, in which the read

41. RemoÃÃo de Ãcidos naftÃnicos presentes na mistura modelo de querosene de aviaÃÃo utilizando adsorventes tipo perovsquitas modificadas
In this work were prepared adsorbents of type perovsquitas La1-xMgxNiO3, where x = 0, 0.25, 0.5, 0.75, 1.0. The addition of magnesium resulted in increased basicity of the material and consequently the affinity of the acids. The adsorbents prepared materials were characterized by atomic absorption espectrofometria (AA), X-ray diffraction (XRD) measurement of

42. Framework para escalonamento distribuído de processos utilizando sistema multiagentes em sistemas de produção
The study of techniques for processes schedulers is linked to the creation of the first operational systems (OS), with the process schedulers algorithms with and without preemption. However, the use of processes schedulers reaches other areas besides OS. It affects all the problems where there is a set of tasks to be executed and a set of executing units. Th

43. Uma proposta de observatório virtual utilizando sistemas multiagentes / A proposal for observatory virtual using system multiagent
The dispersion of information, lack of management of organizational knowledge and the need to integrate various players in a segment is actually common in many areas. In the sector of Microcredit, designed by Prof. Yunus, winner of the Nobel Peace Prize in 2006, it no different. In spite of having ten years of implementation, the industry in Santa Catarina,

44. Computação evolutiva na resolução de equações diferenciais ordinárias não lineares no espaço de Hilbert. / Evolutive computation in the resolution of non-linear ordiinary diferential equations in the Hilbert space.
This thesis shows a new method to get polynomial solutions to the initial value problems (IVP), with an error margin comparable to the consecrate numerical methods (NM), for both the function and its derivatives. The method works with differential equations (DEs) linear or not, beeing the developed tolls available until 4th order, whose can be expanded to hi

46. Estudo de tratamento de interface proveniente de polidutos
The São Paulo Brasília Pipeline (OSBRA), owed by PETROBRAS, starts at the Planalto Refinery (REPLAN) and supplies gasoline, Diesel oil and liquefied petroleum gas (LPG) to the mid-west region of Brazil. The pipeline is 786 kilometers long with diameter of 20 inches in its first segment and 178 kilometers with 12 inches of diameter in the second. The fuels

47. Modelos de simulação para análise e apoio à decisão nos processos de corte mecanizado, carregamento e transporte no agronegócio da cana-de-açúcar / Simulation models for analysis and decision support in the processes of cutting, loading and transport in the agribusiness of cane sugar
In the current days sugarcane occupies an area of approximately 10,5 % of all the Brazilian agricultural land, with an estimated production for the 2008/2009 crop of 528 million t. In the sugarcane production process, the harvest highlights due its high costs, representing approximately 35% of the sugarcane production costs, besides the addition of operation

48. Reúso e minimização do consumo de água em indústrias químicas utilizando a regeneração diferenciada de contaminantes
Currently there is a great demand for tools that allow the analysis of water nets in a practical and objective way. In the modern scenes the chemical, petrochemical, textile and of paper and cellulose industries consume great amounts of water and need to make it in more rational form, because that the water becomes a scarcer natural resource. The methodology
