Atratividade de projetos de software livre: importância teórica e estratégias para administração
(FUNDACAO GETULIO VARGAS, 2010)
Thousands of Free and Open Source Software Projects (FSP) were, and continually are, created on the Internet. This scenario increases the number of opportunities to collaborate to the same extent that it promotes competition ...
Fractal Attraction

Design of reactor-separator-recycle systems based on the optimization of estimations of the domain of attraction
(American Chemical Society, 2011-06)
In this paper, an optimization-based methodology is applied to the design of a reactor-separator-recycle system based on a measure of the extension of the domain of attraction of the operating equilibrium. The approach ...
Silhouette + Attraction: A Simple and Effective Method for Text Clustering
(Cambridge University Press, 2015-08-14)
This article presents Sil-Att, a simple and effective method for text clustering, which is based on two main concepts: the silhouette coefficient and the idea of attraction. The combination of both principles allows to ...
Estimation of domains of attraction: A global optimization approach
(Pergamon-Elsevier Science Ltd, 2010-08)
In this paper a methodology for the estimation of domains of attraction of stable equilibriums based on maximal Lyapunov functions is proposed. The basic idea consists in finding the best level set of a Lyapunov function ...
The influence of planetary attractions on the solar tachocline
(Elsevier, 2012-05)
We present a physical analysis of the occasionally forwarded hypothesis that solar variability, as shown in the various photospheric and outer solar layer activities, might be due to the Newtonian attraction by the planets. ...
On the continuity of pullback attractors for evolution processes
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
In this paper we give general results on the continuity of pullback attractors for nonlinear evolution processes. We then revisit results of [D. Li, P.E. Kloeden, Equi-attraction and the continuous dependence of pullback ...
