O tempo das brincadeiras : memória, turismo e tradição em Barra do Camaratuba PB

Barra do Camaratuba belongs to Mataraca city, nearby the boarder between Paraíba and Rio Grande do Norte states. It was the chosen community to develop this research, objectifying to study the set of practical of the cultural manifestations and the implications of the local tourist activity, considering the cultural dynamics. We tried to reconstruct stories from the narratives of the oldest inhabitants, natives, among others that they had lived, some how, individual and collective experiences related to the popular tricks and the traditional parties, considering what they speak and imagine about their experiences and its culture. The Lapinha, the Pastoril, the viola s songs, the Balls of Concertina, the João Redondo, the Ox of Kings, the wheel of Coconut were common practical perceivable through the communitarian bonds. Among these manifestations, the only one that resisted for a longer time was the wheel coconut. The São Pedro s fest is another popular manifestation that appears on the current scene like the padroeiro party, while others cultural practical compose the spectacle s scenery. These questions cover many of the narratives of the interviewed ones in the interlaced thing between memory, tourism and tradition. Therefore, we tried to build our research from the memory, participant observation, orality, techniques of the life history, personal depositions, among others basic methods for the reconstruction of a collective memory . Speaking about the past of Barra do Camaratuba is to live again the parties, the blood relations, the terço , the work in the roçados , in the flour house, the fishing, the leisure and the habits of the daily life. In this community, there is the presence of conflicts of social and cultural order, caused for the hegemonic classes that sponsor the parties. In the padroeiro party we perceive that the mercantile logic has started, very recently, to transform the religious factor into an excuse to put into motion the local economy. This way, a community originated from artisan fishers and agriculturists, having the fishing practical as a way of subsistence and the tricks as a reference, they had started to compose a new social picture with the arrival of the others and with the presumption and recent tourist development. We perceive social, environmental and cultural impact transformations, exemplified by a non planned activity or a predatory tourism. The changes will always be pointed and compared with other passing in a sphere of relations lived by the natives, local players and fishers

Odometria visual baseada em técnicas de structure from motion

Visual Odometry is the process that estimates camera position and orientation based solely on images and in features (projections of visual landmarks present in the scene) extraced from them. With the increasing advance of Computer Vision algorithms and computer processing power, the subarea known as Structure from Motion (SFM) started to supply mathematical tools composing localization systems for robotics and Augmented Reality applications, in contrast with its initial purpose of being used in inherently offline solutions aiming 3D reconstruction and image based modelling. In that way, this work proposes a pipeline to obtain relative position featuring a previously calibrated camera as positional sensor and based entirely on models and algorithms from SFM. Techniques usually applied in camera localization systems such as Kalman filters and particle filters are not used, making unnecessary additional information like probabilistic models for camera state transition. Experiments assessing both 3D reconstruction quality and camera position estimated by the system were performed, in which image sequences captured in reallistic scenarios were processed and compared to localization data gathered from a mobile robotic platform

Analytical and semi-analytical analysis of an artificial satellite's rotational motion

The rotational motion of an artificial satellite is studied by considering torques produced by gravity gradient and direct solar radiation pressure. A satellite of circular cylinder shape is considered here, and Andoyers variables are used to describe the rotational motion. Expressions for direct solar radiation torque are derived. When the earth's shadow is not considered, an analytical solution is obtained using Lagrange's method of variation of parameters. A semi-analytical procedure is proposed to predict the satellite's attitude under the influence of the earth's shadow. The analytical solution shows that angular variables are linear and periodic functions of time while their conjugates suffer only periodic variations. When compared, numerical and analytical solutions have a good agreement during the time range considered.

Comparison between Two Methods to Calculate the Transition Matrix of Orbit Motion

Two methods to evaluate the state transition matrix are implemented and analyzed to verify the computational cost and the accuracy of both methods. This evaluation represents one of the highest computational costs on the artificial satellite orbit determination task. The first method is an approximation of the Keplerian motion, providing an analytical solution which is then calculated numerically by solving Kepler's equation. The second one is a local numerical approximation that includes the effect of J(2). The analysis is performed comparing these two methods with a reference generated by a numerical integrator. For small intervals of time (1 to 10s) and when one needs more accuracy, it is recommended to use the second method, since the CPU time does not excessively overload the computer during the orbit determination procedure. For larger intervals of time and when one expects more stability on the calculation, it is recommended to use the first method.
