Sistemas computacionais espaço-temporais para toma de decisão em questões ambientais relacionadas à indústria de petróleo e gás

The area between São Bento do Norte and Macau cities, located in the northern coast of the Rio Grande do Norte State is submitted to intense and constant processes of littoral and aeolian transport, causing erosion, alterations in the sediments balance and modifications in the shoreline. Beyond these natural factors, the human interference is huge in the surroundings, composed by sensitive places, due to the existence of the Guamaré Petroliferous Pole, RN, the greater terrestrial oil producing in Brazil, besides the activities of the salt companies and shrimp farms. This socioeconomic-environmental context justifies the elaboration of strategies of environmental monitoring of that coastal area. In the environmental monitoring of coastal strips, submitted to human impacts, the use of multi-sources and multitemporal data integrated through a Spatio- Temporal Database that allows the multiuser friendly access. The objective was to use the potential of the computational systems as important tools the managers of environmental monitoring. The stored data in the form of a virtual library aid in making decisions from the related results and presented in different formats. This procedure enlarges the use of the data in the preventive attendance, in the planning of future actions and in the definition of new lines of researches on the area, in a multiscale approach. Another activity of this Thesis consisted on the development of a computational system to automate the process to elaborate Oil-Spill Environmental Sensitivity Maps, based on the temporal variations that some coastal ecosystems present in the sensibility to the oil. The maps generated in this way, based on the methodology proposed by the Ministério do Meio Ambiente, supply more updated information about the behavior of the ecosystem, as a support to the operations in case of oil spill. Some parameters, such as the hydrodynamic data, the declivity of the beach face, types of resources in risk (environmental, economical, human or cultural) and use and occupation of the area are some of the essential basic information in the elaboration of the sensitivity maps, which suffer temporal alterations.In this way, the two computational systems developed are considered support systems to the decision, because they provide operational subsidies to the environmental monitoring of the coastal areas, considering the transformations in the behavior of coastal elements resulting from temporal changes related the human and/or natural interference of the environment

Códigos de sustentação da linguagem no cotidiano prisional do Rio Grande do Norte: penitenciária estadual de Parnamirim

The quarrel, in this study, tells about the language as social practical in the daily of Parnamirim State Prison that is integrated to the Rio Grande do Norte Penitentiary System - SISPERN, destined for men in fulfilment of penalty privative of freedom, in closed regimen. For the accomplishment of the research, the delimited objectives had been to analyze the language repertoires created in the prisional daily, trying to identify how it´s turned into distinct forms of resistance to the mechanisms of control in penitentiary system; to investigate which are the language repertoires created from the new sociability forms developed among prisoners and identify how the language repertoires are expressed in the daily prisional on relations/exercises of power not-institutionalized. In the methodological aspect, the study is in a qualitative boarding, that has as main instrument the interview. The inquiry was possible by means of using instruments for data collection, like as: the direct comment in the prisional daily duly registered as researcher´s ethnographical procedure, the analysis of interns´ cadastre handbooks and the application of half-structuralized interview, to the subjects of the research. The construction and understanding of the study object had been based on authors who argue on the arrest, as: Foucault, Goffman, Carvalho Filho and, in particular was searched the theorical referencial that approaches the language in a social and cultural perspective: Orlandi, Manfred, Bastos and Candiotto, amongst others. Beyond the normative endorsement of the Brazilian legislation, through the Law of Criminal Execution, of the Criminal Code and the Federal Constitution of the country and the legal apparatus in state scope. Still in the research methodological perspective, after the collection the data had been submitted to an analysis of the speech from Foucalt´s theory and in the Orlandi´s perspective, being also qualitative and quantitative. The results had evidenced that the social and juridical profile of the population in the site inquired is not different of others Brazilian prisons, composed for men, in its majority, with age band between 21 and 30 years old, prisoners for practicing crimes against the patrimony, against life, amongst others, and, in special, criminal recidivists. It evidenced, still, that the daily prisional of PSP is characterized for a sociocultural diversity expressed in the relations of power not institutionalized, that contributes for the formation and division of the groups, each one using a set of language codes/ repertoires sustentation. Therefore, the language, in the daily prisional, is one of the ways to understand the singularity of the sociability relations and as social practicing mediated by relations/exercises of power and antagonistic interests, in which each group aims first of all, their own interests. It represents the complexity of the social relations, in the prisional space, with diverse effects, in function of the situation and the moment. The language in the arrest, beyond the communication function, assumes and represents central element for the sociability human being, contributes for its changings and it´s configured as one of the resistance forms of prisoners against the controling, disciplining and monitoring mechanisms of penitentiary system

Revendo os códigos hamming e CRC para tratar com erros na transmissão de dados

This article has the purpose to review the main codes used to detect and correct errors in data communication specifically in the computer's network. The Hamming's code and the Ciclic Redundancy Code (CRC) are presented as the focus of this article as well as CRC hardware implementation. Each code is reviewed in details in order to fill the gaps in the literature and to make it accessible to the computer science and engineering students as well as to anyone who may be interested in learning the technique to treat error in data communication.

Análise de séries temporais de coordenadas estimadas com gps: Uma proposta metodológica para detecção, remoção e recuperação de efeitos sazonais

GPS active networks are more and more used in geodetic surveying and scientific experiments, as water vapor monitoring in the atmosphere and lithosphere plate movement. Among the methods of GPS positioning, Precise Point Positioning (PPP) has provided very good results. A characteristic of PPP is related to the modeling and / or estimation of the errors involved in this method. The accuracy obtained for the coordinates can reach few millimeters. Seasonal effects can affect such accuracy if they are not consistent treated during the data processing. Coordinates time series analyses have been realized using Fourier or Harmonics spectral analyses, wavelets, least squares estimation among others. An approach is presented in this paper aiming to investigate the seasonal effects included in the stations coordinates time series. Experiments were carried out using data from stations Manaus (NAUS) and Fortaleza (BRFT) which belong to the Brazilian Continuous GPS Network (RBMC). The coordinates of these stations were estimated daily using PPP and were analyzed through wavelets for identification of the periods of the seasonal effects (annual and semi-annual) in each time series. These effects were removed by means of a filtering process applied in the series via the least squares adjustment (LSQ) of a periodic function. The results showed that the combination of these two mathematical tools, wavelets and LSQ, is an interesting and efficient technique for removal of seasonal effects in time series.
