13. Multicolor Quantum Correlations in the Optical Parametric Oscillator / Correlações quânticas multicolores no oscilador paramétrico ótico
We have investigated the collective quantum properties of the three bright light beams produced by an optical parametric oscillator (OPO) operating above threshold, named pump, signal, and idler. We have analyzed experimentally their intensity and phase quantum fluctuations, and how they are correlated. For the first time, we have observed the existence of p

14. Avaliação do modelo 5-scale para simular valores de reflectância de unidades de paisagem da floresta nacional do Tapajós / Evaluation of 5-scale model to simulate reflectance values of landscape units of Tapajós national forest
The increased pressure over natural resources makes efficient planning of its use necessary, as well as monitoring and restraining inadequate and/or illegal practices. For this, remote sensing allied with several specialized areas is presented as an excellent tool. However one of the great challenges of remote sensing is to equate the problem that similar ta

15. Caracterização tecnológica de resíduos de construção e demolição. / Technological characterization of construction and demolition waste.
Construction and demolition waste (CDW) represents around 50% of the total solid waste and are essentially constituted by mineral fraction (>90%); therefore it?s possible to recycle it through mineral processing techniques. The development of different uses and the improvement of the typical technologies applied to CDW recycling are essential to achieve a sa

16. Um modelo consistente para o processo de fotocontagem contínua e medidas de emaranhamento de sistemas quânticos de variáveis contínuas.
This dissertation embraces two trends of research in modern quantum optics. The first of them is connected to the photodetection theory, particularly to the continuous measurement theory developed by Srinivas and Davies (SD) in 1980s, whose principal ingredient is the correct choice of the quantum jump superoperator. We deduce from first principles diff

17. Modelos e algoritmos para problemas de atribuição de capacidade e roteamento em redes de comunicação
The joint problem of selecting routing and a capacity for each link in a communication network is considered. We apply an alternative approach for some models that have been addressed for computer networks discrete capacity allocation and routing problems. The network topology and trac characteristics are assumed to be given. The goal is to obtain a feasible

18. Aplicação das funções de quase-probabilidade no estudo da dinamica de emaranhamento
Entanglement dynamics of two ideal bipartites systems is analyzed using reduced linear entropy and quasiprobability distribution functions in the semiclassical regime.Two models are studied: the quartic bidimensional oscillator and the Dicke ?s Maser model. The first one describes the propagation of two monochromatic field modes in a Kerr medium, and the sec

19. Soil carbon sequestration - Evaluation of its potential in pastures on sandy soils, Anhembi - Piracicaba/SP / Seqüestro de carbono nos solos - Avaliação das potencialidades dos solos arenosos sob pastagens, Anhembi - Piracicaba - SP"
The project studied the potential for soil carbon sequestration in pastures growing on sandy soils in the Cerrado region and for the application of remote sensing techniques for estimating carbon sequestration levels. The main focus was deducing how many tons per hectare could be sequestered if better pasture management techniques were adopted. Four pastures

20. Método de seleção de composições coloridas TM/Landsat para análise de classes de uso da terra / Method of selection of TM/Landsat color composition for analysis of land use classes
The objective of this research is to determine the colour composites generated using digital processing (feature selection and radiometric enhancement) that enhance visual interpretation and improve the separability of land use classes in Conchal, São Paulo State. The procedure used is based on a comparison among thematic classes, taking into consideration

21. Avaliação de técnicas de processamento digital de imagens TM-Landsat aplicadas a delimitações de áreas urbanas / Evaluation of digital processing techniques of TM/Landsat imagery applied to urban area demarcation
The orbital remote sensing can be used to help urban studies, owing to the possibility of obtaining images of regional ambit and quasi-real time information, allowing the limits definition and urban monitoring. In this work we used Thematic Mapper Sensor (TM) data, in CCT, of Sao José dos Campos city, São Paulo State, to: 1) identify the best band of TM se

23. Genetic separability of the chorismate mutase and prephenate dehydrogenase components of the Escherichia coli tyrA gene product.
Fragments of the tyrA gene of Escherichia coli, when suitably engineered, can express either the chorismate mutase activity or the prephenate dehydrogenase activity without the other.

24. Memory effects and oscillations in single-molecule kinetics
An exactly solvable model for single-molecule kinetics is suggested, based on the following assumptions: (i) A single molecule can exist in different chemical states and the random transitions from one chemical state to another can be described by a local master equation with time-dependent transition rates. (ii) Because of conformational and other intramole
