1. Temporal Evolution of Roughness Development on Polymer Surfaces Exposed to Non-Thermal Plasma
Processes such as ablation, erosion and corrosion generally create roughness patterns on solid surfaces. Despite the randomness of this phenomenon, some patterns can be described mathematically by studying statistically the mechanisms behind them. This paper reports an experimental study on the temporal evolution of the roughness development of polymer surfa

3. Estimação de modelos de estrutura a termo: aplicação para o Brasil dos modelos afim de Vasicek e CIR 2009 / Estimation of term structure models: application to Brazil of affine models Vasicek and CIR. 2009
In this work, we studied the Brazilian term structure of interest rate for the recent period, from January 2004 to March 2009, exploring the characteristics implied in the swap rates and ID contracts. Based on the theoretical framework of affine models, we analyze the models of Vasicek (1977) and Cox, Ingersoll and Ross (1985), two particular cases of affine

4. Modelagem matemÃtica com simulaÃÃo computacional na aprendizagem de funÃÃes
This research investigated mathematics modeling as an approach to learn the concept of affine, quadratic and exponential functions, on activities of building computer simulations. Our concerns were to identify mathematical and computational abilities mobilized while students use function knowledge on modeling simulations. This led us to search tools to the r

5. UMA ANÁLISE EMPÍRICA PARA A ESTRUTURA A TERMO DA TAXA DE JUROS BRASILEIRA: USANDO O ALGORITMO DO FILTRO DE KALMAN PARA ESTIMAR OS MODELOS DE VASICEK E COX, INGERSOLL E ROSS / AN EMPIRICAL ANALYSIS OF THE BRAZILIAN TERM STRUCTURE OF INTEREST RATES: USING THE KALMAN FILTER ALGORITHM TO ESTIMATE THE VASICEK AND COX, INGERSOLL AND ROSS MODELS
The importance of the term structure of interest rates is hardly exaggerated. The term structure succinctly summarizes an enormous quantity of information about the actual state and about the future expectations of/ for the economy of a country. Within this work, using Kalman filter estimation techniques, we estimate, with Brazilian data, four different mode

6. A dynamical systems perspective on the relationship between symbolic and non-symbolic computation
It has been claimed that connectionist (artificial neural network) models of language processing, which do not appear to employ “rules”, are doing something different in kind from classical symbol processing models, which treat “rules” as atoms (e.g., McClelland and Patterson in Trends Cogn Sci 6(11):465–472, 2002). This claim is hard to assess in
