  1. A mathematical modeling applied to the study of two forms of artistic representation

    Marins de Carvalho, Henrique; Bassanezi, Rodney Carlos; Pompeu Junior, Geraldo
    [EN] The cultural manifestation of the Arican indigenous people from Chile, through the designs found in their garments was analyzed. Comparing their techniques of mosaic formation, using geometric transformations (bijection plans in itself ), it was investigated whether, mathematically, its evolution could be explained. The mosaics, as well as the known works of Escher, are constructed from the application of translations, rotations, reflections or slip reflections of an initial motif (a rosette). With similar purpose —understanding the relationship between music and the evolution and complexity of a possible mathematical representation— were analyzed the geometric transformations and excerpts from three works of Johann Sebastian Bach. It is concluded,...

  2. Implementaçao de um modelo para o cálculo do excedente hídrico por geoprocessamento de dados meteorológicos

    Aguilar Muñoz, Viviana; Ribeiro Viana, Denilson
    [EN] This work aimed application of a methodology for calculating and plotting spatial distribution of water surplus by processing meteorological data in Geographic Information Systems. In this experiment, we used precipitation and temperature data collected from weather stations, as well as elevation data from Shuttle Radar Topography Mission, SRTM. Monthly input data from the specific comments was use for surface meteorological variables generation. The algorithm for calculating the water surplus based on pre-existing developments, using the equations of fluid balance of Thornthwaite & Mather. We observed both a good performance of the algorithms and its replicability. However, over the results obtained in this work for the study...

  3. HydroC - Biblioteca hidrológica aberta com fins educacionais

    Lima Santos, Leonardo Bacelar; Miranda, Tiago Nogueira Sá; Décia Fratari, Jéssika Caroline; Baldo Bacelar, Roberta; Medina, Camila Beltrão; de Carvalho, Solon Venâncio
    [EN] The physical object of watershed is so important for hydrological monitoring as their concept is for education in natural disasters. The open library HydroC promotes the delineation of watersheds from relatively simple functions, developed for educational purposes. A case study was done with students of Introduction to Computer Science with an undergraduate degree in Environmental Engineering. The creation of HydroC and its delivering in a collaborative, free and open platform make this proposal an interesting alternative education resource about natural disasters.

  4. Experiences with a Socio-Environmental Modeling Course

    Andrade, Pedro Ribeiro; Camara, Gilberto; Maretto, Raian V.; Monteiro, Antonio Miguel V.; Carneiro, Tiago G. S.; Feitosa, Flavia F.
    [EN] In a social-environmental modeling course, students need to learn complementary skills that include the conceptualisation of a model, different modeling paradigms, computer programming, and the process of rigorously converting ideas and data into a computational program using a given toolkit. Such topics need to be taught in parallel in order to keep a heterogeneous audience motivated. Based on the experience with multidisciplinary audiences, this paper describes a socio-environmental modeling course that explores three modeling paradigms: System dynamics, Cellular automata, and Agent-based modeling. We also present a small tutorial with some examples developed for the course.

  5. Classificação de Strahler para hidrografias brasileiras relacionadas a desastres naturais

    Souza Jorge, Aurelienne Aparecida; Santos da Silva, Aline Cristina; de Mello Anaya, Larissa; Rodrigues do Nascimento, Jether; Lima Santos, Leonardo Bacelar
    [EN] Flood is one of the most frequent natural disaster in Brazil. The watercourses classification in the watershed’s drainage system is one of the resources of the Hydrological Intelligence - essential to natural disasters monitoring and early warning. Exclusively based on free files and softwares, it is presented a set of procedures for Strahler classification of a hydrography, with results presented for rivers with meaningful history and risk of natural disasters: Itaja´ı, Paraiba do Sul and Doce. The results presentation, with possibilities for education in natural disasters, is done on a free Geographical Information System (QuantumGIS) and on an innovative platform (SALVAR-Cemaden), which is aimed to...

  6. Toxicological risk assessment of complex mixtures through the WTox model

    Matias, William Gerson; Flohr, Letícia
    [EN] Mathematical models are important tools for environmental management and risk assessment. Predictions about the toxicity of chemical mixtures must be enhanced due to the complexity of effects that can be caused to the living species. In this work, the environmental risk was accessed addressing the need to study the relationship between the organism and xenobiotics. Therefore, five toxicological endpoints were applied through the WTox Model, and with this methodology we obtained the risk classification of potentially toxic substances. Acute and chronic toxicity, citotoxicity and genotoxicity were observed in the organisms Daphnia magna, Vibrio fischeri and Oreochromis niloticus. A case study was conducted with solid wastes from...
