1. Gestão de agregados minerais : análise e subsídios para políticas públicas / Management ggregates : comparite analysis betwen Canada and Brazil and subsidies for public policies
The biophysical and social disruption caused by aggregates mining has placed it at the center of conflict scenarios, either because of advancing urbanization on the aggregates resources or because of pressures from civil society to impose restrictions on their development. The search for solutions to this problem has required of the governments a large abili

2. Production strategy in supply chain: case study in small companies in civil construction / Estratégia de produção em cadeia de suprimentos : estudos de caso em pequenas empresas da construção civil
Many companies from many different business sectors are beginning to implement the developments stemming from the area of supply chain management to gain competitiveness in the market. In order to contribute to the growing understanding of production management in companies that are part of supply chains, this paper aims to identify and analyze production st

3. Fuzzy inference systems approach for long term hydrothermal scheduling / Sistema de inferencia nebulosa ao planejamento da operação hidrotermica de medio prazo
The long term hydrothermal scheduling lies in the optimization of the water resource usage through the maximization of the hydroelectric production and the minimization of the thermal plants operation. Its goal is to assure an economic and reliable load supply throughout the study stages. This problem can be characterized by exhibiting a complex nature, sinc

4. Nonlinear dynamics of nonideal rotor / Dinamica não-linear de um rotor não-ideal
Esse trabalho investiga um sistema dinâmico não- ideal que pertence a uma classe especial dos sistemas dinâmicos. O objeto de estudo desse trabalho é um rotor que consiste de um disco preso a uma barra elástica e excitado por uma fonte de energia de potência limitada. O sistema se desloca transversalmente e verticalmente além de possuir uma coordenada

5. Selection of potential areas for hydrical resource in the hydrographic basin of Rio Paraiba do Sul, São Paulo - Brazil / Seleção de areas potenciais para recursos hidricos na bacia hidrografica do Rio Paraiba do Sul, São Paulo - Brasil
The necessity of Public Political that give support to a sustainable development, in the current times is a premise that must be followed. The control and the aiming of the actions of the man on this space must be with priority. Areas as the hydrographic basins must be seen with bigger detailing, therefore in general, the same ones present a capacity of supp

6. Vibrations of a parametrically and self-Excited system with ideal and non-ideal energy sources
Interactions between parametric, self-, and externally excited vibrations are analysed in this paper. The physical model of the vibrating system consists of a non-linear spring with periodically changing stiffness of Mathieu type and a non-linear damping described by Rayleigh's term. This system is additionally forced by a harmonic force (ideal system), or b

7. OPTIMUM PRICE BIDDING STRATEGY IN THE SHORT-TERM MARKET OF HYDRO-DOMINATED ELECTRIC SYSTEMS / ESTRATÉGIA ÓTIMA DE OFERTA DE PREÇOS NO MERCADO DE CURTO PRAZO EM SISTEMAS COM PREDOMINÂNCIA HIDRELÉTRICA
In perfectly competitive markets, there are no loopholes that can be exploited by agents to maximize profit through non-competitive behavior. However, electricity markets look more like an oligopoly than perfectly competitive markets. If competition is not perfect, generation agents may try to establish optimum price bidding strategies to maximize profits. I

8. Aplicações de sistemas classificadores para robotica autonoma movel com aprendizado
Mobile robotics has as its fundamental goal to elaborate trajectories avoiding collisions, locating and reaching targets, power supply self sufficiency, objects transportation, etc. A solution providing autonomy to the robot for learning its behavior is contrasting with more classical approaches that require a previous model of the environment in which the r

9. Qualidade em ambiente de burocracia: o caso da Justiça Federal do Estado do Amazonas
The necessity to be efficient and effective has long shifted from the private to the public sector. New philosophies have appeared with the aim to supply better performance in both private and public organisms. One of those theories is Quality. It stresses that people who are part of an organisation must realise that they are customers and suppliers within

11. Lasers semicondutores em cavidade estendida aplicados a espectroscopia de alta resolução
We use an Extended Cavity Semiconductor Laser (ECSL) to overcome some drawbacks of solitary diode lasers as limited tuning range, large linewidth and inaccessible spectral regions. The Litman-Metcalf configuration was used because of its several advantages, e.g., a very small passband due to using a grating in double passage grazing incidence. This laser con

12. Projeto, desenvolvimento e construção de uma fonte de alta tensão pulsada para polarização de valvulas Klystron
A pulsed high voltage power supply, used for feeding a Klystron RF amplifier, in the Laboratorio Nacional de Luz Síncroton (LNLS) linear accelerator (LlNAC) is described. The design, development, assembling and constructive details are included. The system, named modulator, provides a 3 ?mu?s pulses of 250 kV and 250 A, with voltage stability better than 1%
