1. Study of mixers fertilizers plants localization in brazilian Center-West region using a linear programming model / Estudo de localização de fábricas misturadoras de adubo na região Centro-Oeste brasileira utilizando um modelo de programação linear
Currently, the brazilian agribusiness is responsible for about 37% of the national PIB and face up to two of the great challenges in its constant growth which are the high dependence of chemical products (fertilizers) to expand its agricultural frontier and consequently, the distance (and transports costs) that this frontiers impose to be overcome, as much f

2. Services allocation in a metrology laboratory using genetic algorithms / Distribuição de serviços em laboratório de metrologia utilizando algoritmos genéticos
As simple as it might look, the problem of allocating a group of tasks to be executed with a limited number of available machines will always present a number of details and restrictions that in certain cases can result in a solution of great complexity. Some of the variables involved are: service priority, available raw materials, machinery or equipment cap

3. The mathematics in the project Science in the School : the seacrch for the autonomy of students / A matematica no projeto Ciencia na Escola : a busca da autonomia dos alunos
This present research was developed of public elementary school in the period between 1997 and 2004, work was mediated by the group of teachers and students in collaborative action, based on the principles of the project "Ciência na Escola" The actions occurred in two moments, which marked significantly the practice of the classroom. The qualitative researc

4. Otimização de fluxo em redes na gestão financeira do caixa: aplicação em uma empresa do setor agroindustrial / CASH FLOW MANAGEMENT OPTIMIZATION WITH NETWORK FLOW: APLICATION TO THE AGRO-INDUSTRY / Otimização de fluxo em redes na gestão financeira do caixa: aplicação em uma empresa do setor agroindustrial / CASH FLOW MANAGEMENT OPTIMIZATION WITH NETWORK FLOW: APLICATION TO THE AGRO-INDUSTRY
Cash flow management is a financial problem that involves the efficient management of cash, short-term investments and short-term loans. In this study, we formulate the cash flow problem encountered in a typical agro-industrial company as a network optimization problem. Two examples using a linear programming model were studied: in the first example, the ori

5. Phisical distribution networks optimization considering fiscal benefits based on presumed credit of ICMS. / Otimização de redes de distribuição física considerando incentivo fiscal baseado no crédito presumido de ICMS.
This research evaluates the influence of some specific fiscal benefits related to current states sale taxes for internal and interstate operations over distribution center location decisions. The objective is to develop a mathematic model that determines a distribution network with lower cost considering fiscal benefits based on presumed credit, which is cal

6. Processamento paralelo na simulação de campos eletromagnéticos pelo método das diferenças finitas no domínio do tempo - FDTD. / Parallel processing in the electromagnetic fields simulation with the finite-difference time-domain method - FDTD.
São crescentes as pesquisas e os projetos envolvendo o eletromagnetismo. Tanto para as pesquisas quanto para os projetos, tem-se o recurso de realizar simulações computacionais dos problemas envolvidos, a fim de investigar o comportamento dos fenômenos eletromagnéticos diante da situação na qual encontram-se. Há casos, contudo, em que o problema pode

7. Sistemas multiagentes para controle inteligente da caldeira de recuperação. / Multi-agent systems for the intelligent control of a recovery boiler.
Engineers have been introducing better support for procedures of monitoring complex conditions through the application of intelligent decentralized systems, implementing a variety of artificial intelligent techniques. Nowadays it is vastly known that these problems that are consequence of the functional complexity of monitoring conditioning can be solved tro

8. Integration of functional programming and spatial databases for GIS application development / Integração de programação funcional e banco de dados espaciais no desenvolvimento de aplicativos geográficos
A pesquisa recente em geoinformação indica que há benefícios no uso de programação funcional aplicada ao desenvolvimento de aplicativos geográficos. No entanto, o desenvolvimento completo de um sistema de geoinformação em linguagem funcional não é factível. O acesso a banco de dados geográfico exige um grande conjunto de operações de entrada e

9. Integration of functional programming and spatial databases for GIS application development / Integração de programação funcional e banco de dados espaciais no desenvolvimento de aplicativos geográficos
Recently, researchers in GIScience argued about the benefits on using functional programming for geospatial application development and prototyping of novel ideas. However, developing an entire GIS in a functional language is not feasible. Support for spatial databases requires a large set of I/O operations, which are cumbersome to implement in functional la

10. Otimização de seções transversais de concreto armado: aplicação a pórticos planos / Reinforced concrete cross-section cost optimization: a plane frame application
A computational routine developed to optimize the first draft design of reinforced concrete buildings, approximated by plane frames. The commercial softwares used by the engineering offices for structural design is usually based in a first draft design, being this essential stage still accomplished by the engineer´s experience and intuition, using attempt a

12. Otimização no corte de tubos estruturais: aplicação na indústria aeronáutica agrícola.
The Cutting Stock Problem consists of determining the best form to cut units of material (objects in supply), producing a set of lesser units (demanded item), with specific dimensions, that are ordered through an order wallet. To minimize the loss of material this study described a method of evaluation and optimization of the process planning of the cu
