1. Mobility Data under Analysis a Complex Network Perspective from Interactions Among Trajectories to Movements among Points Interest
The explosion of personal positioning devices like GPS-enabled smartphones has enabled the collection and storage of a huge amount of positioning data in the form of trajectories. Thereby, trajectory data have brought many research challenges in the process of recovery, storage and knowledge discovery in mobility as well as new applications to support our so

2. Aspectos dinâmicos de espalhamento caótico clássico / Dynamical aspects of classical scattering
In this thesis we study different scattering systems with chaos. Chaotic scattering, present in a large variety of physical systems, is a type of transient chaos. While the phase-space of such systems is unbounded, irregular motion occurs only in a bounded area, called the scattering region. Still, any (nontrivial) scattering function relating initial condit

3. Design and fabrication of a mobile part of a human hand prothesis / Projeto e construção de parte estrutural de protese de mão humana com movimentos
Devido ao grande número de pessoas que necessitam do uso de prótese para substituir um membro com seu funcionamento normal afetado, seja por deficiência congênita ou nos casos em que haja necessidade de remoção, ocasionada por doenças ou lesões com trauma, como acidentes do trabalho e de trânsito, foi desenvolvido neste trabalho o projeto e constru�

4. Parâmetros de fonte de microterremotos em Cascavel-CE
In this dissertation it was studied the rupture characteristic of earthquakes of the Town of Cascavel CE, Northeastern Brazil. Located on the border of the Potiguar Basin, the Town of Cascavel is one of the most seismically active intraplate areas in the country. In this town, on November 20th, 1980 a 5,2mb earthquake occurred. This was the largest earthquak

5. Análise de cerâmicas arqueológicas do Sambaqui do Bacanga (São Luís, MA) por EDXRF portátil
Sambaqui do Bacanga archaeological site is located in the Island of São Luis -Maranhão Brazil, in the region bathed by the Bacanga River. A tratigraphic collection of 78 ceramic fragments was collected during the years 2005 and 2006, to perform a qualitative analysis of the chemical elements employing a Portable System of Energy Dispersive X-ray Flu

6. Vegetation and soil gradient in the restinga forest in Espirito Santo, Brazil / Gradiente vegetacional e pedológico em floresta de restinga no Espírito Santo, Brasil
The Restingas are ecosystems that occur in sandy soils deposited during the Quaternary. These are known to have a high diversity of vegetation, but few studies provide information on abiotic factors determining this diversity. This study aimed to: (i) assess the influence of the chemical aspects, physical soil and flooding in phytophysionomic determination,

7. Study of nickel catalysts supported on modified ZrO2 applied in reforming reactions / Estudo de catalisadores de níquel suportados em ZrO2 modificados aplicados em reações de reforma
Zirconium dioxide is a material with physics and chemical characteristics that can be applied in many fields, as academic as industrial. In the catalysis, the interest in systems based on zirconia (ZrO2) are growing- up quickly, as a catalyst as a support, considering that ZrO2 properties can be changed by the addition of different cations. The objective of

8. Field soil hydraulic conductivity: the simplification of the instantaneous profile method. / Condutividade hidráulica do solo no campo: as simplificações do método do perfil instantâneo.
The soil hydraulic conductivity is a parameter that quantifies the ability of the soil to conduct water along the soil profile. Hence its field determination is indispensable, since soil water movement is directly related to the field crop productions. Thus, the use of an adequate method that assesses the hydraulic conductivity as a function of soil-water co

9. From deterministic dynamics to probabilistic descriptions
The present work is devoted to the following question: What is the relationship between the deterministic laws of dynamics and probabilistic description of physical processes? It is generally accepted that probabilistic processes can arise from deterministic dynamics only through a process of “coarse graining” or “contraction of description” that ine
