Large deflection of a non-linear, elastic, asymmetric Ludwick cantilever beam subjected to horizontal force, vertical force and bending torque at the free end
No full textThe investigated cantilever beam is characterized by a constant rectangular cross-section and is subjected to a concentrated constant vertical load, to a concentrated constant horizontal load and to a concentrated constant bending torque at the free end. The same beam is made by an elastic non-linear asymmetric Ludwick type material with different behavior in tension and compression. Namely the constitutive law of the proposed material is characterized by two different elastic moduli and two different strain exponential coefficients. The aim of this study is to describe the deformation of the beam neutral surface and particularly the horizontal and vertical displacements of the free end cross-section. The analysis of large deflection is based on the Euler-Bernoulli bending beam theory, for which cross-sections, after the deformation, remain plain and perpendicular to the neutral surface; furthermore their shape and area do not change. On the stress viewpoint, the shear stress effect and the axial force effect are considered negligible in comparison with the bending effect. The mechanical model deduced from the identified hypotheses includes two kind of non-linearity: the first due to the material and the latter due to large deformations. The mathematical problem associated with the mechanical model, i.e. to compute the bending deformations, consists in solving a non-linear algebraic system and a non-liner second order ordinary differential equation. Thus a numerical algorithm is developed and some examples of specific results are shown in this paper. © Springer Science+Business Media Dordrecht 2014
Measuring non-Markovianity via incoherent mixing with Markovian dynamics
Full text linkWe introduce a measure of non-Markovianity based on the minimal amount of extra Markovian noise we have to add to the process via incoherent mixing, in order to make the resulting transformation Markovian too at all times. We show how to evaluate this measure by considering the set of depolarizing evolutions in arbitrary dimension and the set of dephasing evolutions for qubits
Editors' Introduction
No full textThis introductory note explain the importance of exploring the relation between Husserl's phenomenology on the one hand and Platonism and Aristotelianism on the other. This is a topic that has been little treated in the literature that can no longer be ignored given its importance to correctly frame the theoretical status of phenomenolog

No full textInterethnic feminine gender: a pilot research
No full textOur research analysed the feminine role, status, and cultural expectations in Italian, Chinese, Bulgarian/
Romanian, and Albanian communities in Italy. It involved three steps. Firstly, guided interviews were administrated
to 70 males and 70 females, all aged 25-40, from each group to investigate how they viewed the
feminine role, men’s idea of the ideal woman, how women internalized their own role, and how they fit into their
traditional gender role. The scores showed stereotypical perceptions with little differences between groups. The
Bem Sex-Role Inventory was then applied to assess the convergence/disagreement between expected traits and
real status. Data, correlated with social indicators and compared among the groups, suggested a tendency in all
groups to achieve higher scores on the femininity scale. These scores confirmed the self/other descriptions in the
first step, emphasizing separate spheres of influence for women and men. Finally, Gilligan and Noddings’ models
of moral reasoning were administrated to prove the correlation between the previous scores concerning gender
identity and a propensity to caring, relationships and responsibilities as feminine characteristics. These scores
contrasted with those of the former steps, showing a tendency to the masculine style of reasoning based on jus49
tice, rights, and decision-making. This analysis suggests that more reflection is needed on ethical rather than ethnic differences
