13. Food web and ecological models used to assess aquatic ecosystems submitted to aquaculture activities
RESUMO: Ecossistemas aquáticos continentais desempenham papel fundamental no desenvolvimento econômico e social, entretanto, são vulneráveis à degradação ambiental devido às diversas pressões a que estão submetidos. Entre as principais atividades antrópicas a interferir nestes ambientes, podemos destacar a aquicultura. A modelagem matemática de

14. La representación de documentos y autoridades archivísticas: una mirada desde la perspectiva de la normalización
ABSTRACT Nowadays, the archival science is going through a big changes in its conception as science. As a result, the discipline has gone from the inactivity in the normalization of their tasks to the regulatory action of most its processes. In the late twentieth century, institutions such as the International Council on Archives and prestigious associations

15. An Efficient Human Identification through MultiModal Biometric System
ABSTRACT Human identification is essential for proper functioning of society. Human identification through multimodal biometrics is becoming an emerging trend, and one of the reasons is to improve recognition accuracy. Unimodal biometric systems are affected by various problemssuch as noisy sensor data,non-universality, lack of individuality, lack of invaria

16. La nueva gramática democrática frente a la integración autónoma latinoamericana y caribeña
The "market's democratization and the liberal democratization's" purpose it's to soften the systemic and global crisis of Latin America, a region whose historical memory registers harsh processes of market authoritarianism over its political systems. The procedural democracy and the multiparty political system monopolize the representation, pretending to be

17. Decomposition approach for generation and transmission expansion planning with implicit multipliers evaluation
In an electric power systems planning framework, decomposition techniques are usually applied to separate investment and operation subproblems to take benefits from the use of independent solution algorithms. Real power systems planning problems can be rather complex and their detailed representation often leads to greater effort to solve the operation subpr

18. Uma proposta de protocolo de codificação de libras para sistemas de tv digital.
Nowadays, the digital television systems do not have specific standards for sign languages (SL). The solution used in TV is to transmit a window with a SL interpreter over the video program. This solution is ineffective in several aspects: it has high operational costs, is dependent of a interpreter, and distract nondeaf viewers. In addition, it does not res

19. Geração de b-splines via FPGA / B-spline generation via FPGA
The b-splines are used in CAD/CAM/CAE systems to represent and define complex curves and surfaces, being adopted by the main computer graphics standards due to features like compact mathematic representation, flexibility and affine transformations. In 3D acquisition systems and integrated CAM-CNC systems, the use of the b-spline in the geometric information

20. Evolving granular systems = : Sistemas granulares evolutivos / Sistemas granulares evolutivos
In recent years there has been increasing interest in computational modeling approaches to deal with real-world data streams. Methods and algorithms have been proposed to uncover meaningful knowledge from very large (often unbounded) data sets in principle with no apparent value. This thesis introduces a framework for evolving granular modeling of uncertain

21. Three-phase representation of structural and operational unbalances on distribution system / Representação trifásica de desequilíbrios estruturais e operacionais em sistema de média tensão de distribuição
A complexidade crescente dos estudos em sistemas de distribuição demanda uma formulação e modelagem capazes de agregar os desequilíbrios estruturais e operacionais dos sistemas elétricos de distribuição aos resultados das condições operacionais em regime permanente. Neste trabalho, aborda-se a representação trifásica em sistemas elétricos de m�

22. Produção de gases de efeito estufa e potencial de geração de créditos de carbono em processos de tratamento de esgoto sanitário
The concept of carbon credits came from the awareness of need to reduce greenhouse gas (GHG) emissions in order to combat the worsening of global warming, discussed and formalized in the Kyoto Protocol. Emission of greenhouse gases as methane, nitrous oxide and carbon dioxide is due to several activities, among them the wastewater treatment, both domestic an

The faxinal landscape is a complex system resulting from the interaction between nature and traditional rural communities that develop production practices joined to a system of knowledge and representation of landscapes. The actions, experimented practices in relationship between man and nature enable the individuals to formulating and improving knowledge,
