In this paper, some modified Newton’s methods for solving nonlinear equations are proposed. Householder and Halley have suggested a variant of New- ton’s method in which they take an osculating parabola respectively an hyperbola instead of the tangent line. The proposed methods go faster to approximated solution, but it requires more calculation efforts. The order of convergence of both methods is three. By some interesting numerical problems, the theoretical results are illustrated. In the appendix, we give a foretaste of the proposed methods in the complex plane. [less ▲]

This paper provides a computational characterisation of human mate choice. In terms of evolutionary biology, choosing the "best" mating strategy is a matter of maximising the trade-offs resulting from the costs and benefits associated with any activity "aiming" at survival and reproduction, like living to reproductive age, displaying desirable features, courting, mating, parenting, etc. Evolved mating strategies can descriptively be characterised as such cost/benefit analyses (or conditional strategies). They should take into account the effects of those biological, ecological, populational, social and cultural constraints that were recurrently affecting the long- term inclusive fitness of our hominid ancestors. Similarly, in terms of evolutionary cognitive science, choosing the "best" mate is a matter of maximising satisfaction of a set of positive and negative constraints affecting inclusive fitness. Overall mate attractiveness is conjectured to be the product of this dynamic multiple constraint satisfaction process. It is, moreover, shown that a computational metaphor based on parallel distributed processing captures essential features of human mate choice, like infatuation and the "beautiful-is-good" effect. It also provides an integrating view on the numerous preference factors documented to affect perceived mate value. Finally, the author proposes new empirical predictions about constraints on overall mate attractiveness to be explored in future multidisciplinary studies. [less ▲]

Hannsjörg Voth produces with the evident necessity of high physical endurance art projects with mythical and utopian contents. The creations of the artist touch so many artistic domains that it is not possible to attach him to a single typology of art expression. The present research features an analyze and an interpretation of Voths’ artwork in the setting of his personal artistic evolution. In his creative approach, the methodical progress to accomplish what is called in this research an art project, is studied in all its sequences in order to define in a more clear way this new artistic expression. It tries not only to overcome the traditional supports but also includes modern medias, so as photos and videos as integral and essential parts of the artists’ works. A confrontation with the art of the past and simultaneously contemporary creative expressions allows to better define the art coordinates of Voth and to give an evaluation of originality and artistic quality in the context of countless aesthetic forms that represent visual arts at the end of the XXth century.
