    • Dynamic transitions in a three dimensional associating lattice gas model 

      Szortyka, Marcia Martins; Girardi, Mauricio; Henriques, Vera Bohomoletz; Barbosa, Marcia Cristina Bernardes (2010) [Artigo de periódico]
      We investigate the thermodynamic and dynamic properties of a three dimensional associating lattice gas (ALG) model through Monte Carlo simulations. The ALG model combines a soft core potential and orientational degrees of ...

    • Dynamic transitions in a two dimensional associating lattice gas model 

      Szortyka, Marcia Martins; Henriques, Vera Bohomoletz; Girardi, Mauricio; Barbosa, Marcia Cristina Bernardes (2009) [Artigo de periódico]
      Using Monte Carlo simulations we investigate some new aspects of the phase diagram and the behavior of the diffusion coefficient in an associating lattice gas (ALG) model on different regions of the phase diagram. The ALG ...

    • Dynamic transmission modeling of COVID-19 to support decision-making in Brazil : a scoping review in the pre-vaccine era 

      Almeida, Gabriel Berg de; Simon, Lorena Mendes; Bagattini, Ângela Maria; Rosa, Michelle Quarti Machado da; Borges, Marcelo Eduardo; Diniz Filho, José Alexandre Felizola; Kuchenbecker, Ricardo de Souza; Kraenkel, Roberto André; Ferreira, Cláudia Pio; Camey, Suzi Alves; Fortaleza, Carlos Magno Castelo Branco; Toscano, Cristiana Maria (2023) [Artigo de periódico]
      Brazil was one of the countries most affected during the first year of the COVID-19 pandemic, in a pre-vaccine era, and mathematical and statistical models were used in decisionmaking and public policies to mitigate and ...

    • Early appraisal of the fixation probability in directed networks 

      Barbosa, Valmir Carneiro; Donangelo, Raul José; Souza, Sergio Ricardo de Azevedo (2010) [Artigo de periódico]
      In evolutionary dynamics, the probability that a mutation spreads through the whole population, having arisen from a single individual, is known as the fixation probability. In general, it is not possible to find the ...

    • O eclipse solar e as imagens do sol observadas no chão ou numa parede 

      Silveira, Fernando Lang da; Axt, Rolando (2007) [Artigo de periódico]
      Luz filtrada através das folhas da vegetação produz círculos e elipses luminosas no chão ou em paredes. Justificamos que essas figuras são imagens do Sol. Imagens semelhantes também são obtidas pela luz refletida em um ...

      Livi, Silvia Helena Becker (1993) [Artigo de periódico]
      Resumo não disponível

    • Eclipsing binary science via the merging of transit and doppler exoplanet survey data - a case study with the marvels pilot project and SuperWASP 

      Fleming, S.W.; Maxted, Pierre F.L.; Hebb, Leslie; Stassun, Keivan G.; Ge, Jian; Cargile, Phillip A.; Ghezzi, Luan; De Lee, Nathan M.; Wisniewski, J.P.; Gary, Bruce L.; Mello, Gustavo Frederico Porto de; Ferreira, Letícia D.; Zhao, Bo; Anderson, D.R.; Wan, Xiaoke; Hellier, C.; Guo, Pengcheng; West, R.G.; Mahadevan, Suvrath; Pollacco, Don; Lee, B.L.; Collier Cameron, A.; Van Eyken, Julian C.; Skillen, Ian; Crepp, Justin R.; Nguyen, D.C.; Kane, Stephen R.; Paegert, Martin; Costa, Luiz N. da; Maia, Marcio Antonio Geimba; Santiago, Basilio Xavier (2011) [Artigo de periódico]
      Exoplanet transit and Doppler surveys discover many binary stars during their operation that can be used to conduct a variety of ancillary science. Specifically, eclipsing binary stars can be used to study the stellar ...

    • Econometria e verificabilidade de teorias econômicas 

      Crusius, Carlos Augusto (1990) [Artigo de periódico]
      Resumo não disponível

    • Econometria e verificação de teorias econômicas 

      Crusius, Carlos Augusto (1993) [Artigo de periódico]
      O artigo mostra que a necessidade do uso de testes estatísticos introduz no processo de avaliação empírica de teorias econômicas um tipo especial de inconclusividade, que deslegitima tanto a confirmação a la Camap como a ...

    • Economia de átomos, engenharia molecular e catálise organometálica bifásica : conceitos moleculares para tecnologias limpas 

      Dupont, Jairton (2000) [Artigo de periódico]
      For economical and ecological reasons, synthetic chemists are confronted with the increasing obligation of optimizing their synthetic methods. Maximizing efficiency and minimizing costs in the production of molecules and ...

    • Economic valuation of selected coastal ecosystems based on key provisioning and regulation services of Jaguaruna (Brazil) 

      Sfreddo, Giuliana Andréia; Chica Ruiz, Juan Adolfo; Silva, Tatiana Silva da; Barboza, Eduardo Guimarães (2023) [Artigo de periódico]
      The search for sustainability can be understood as a trajectory towards the maintenance of ecosystem services, which includes ways of minimizing the risk of losing them due to some imminent coastal hazard. Thus, this study ...

    • Edge atoms effects on the perpendicular anisotropy of ultrathin magnetic layers 

      Geshev, Julian Penkov; Gundel, Andre; Zaharieva, Ivelina; Schmidt, Joao Edgar (2012) [Artigo de periódico]
      The present work reports experimental and theoretical results for electrodeposited Co/Au(111) ultrathin layers with very specific magnetic behavior. We show that the observed two peaks in the out-of-plane magnetization ...

    • Edge Groups : an approach to understanding the Mesh quality of Marching Methods 

      Dietrich, Carlos Augusto; Scheidegger, Carlos Eduardo; Comba, Joao Luiz Dihl; Nedel, Luciana Porcher; Silva, Cláudio Teixeira (2008) [Artigo de periódico]
      Marching Cubes is the most popular isosurface extraction algorithm due to its simplicity, efficiency and robustness. It has been widely studied, improved, and extended. While much early work was concerned with efficiency ...

    • Edge transformations for improving mesh quality of marching cubes 

      Dietrich, Carlos Augusto; Scheidegger, Carlos Eduardo; Schreiner, John; Nedel, Luciana Porcher; Comba, Joao Luiz Dihl; Silva, Cláudio Teixeira (2009) [Artigo de periódico]
      Marching Cubes is a popular choice for isosurface extraction from regular grids due to its simplicity, robustness, and efficiency. One of the key shortcomings of this approach is the quality of the resulting meshes, which ...
