Dark Universe and distribution of Matter as Quantum Imprinting: the Quantum Origin of Universe

In this paper we analyze the Dark Matter problem and the distribution of matter through two different approaches, which are linked by the possibility that the solution of these astronomical puzzles should be sought in the quantum imprinting of the Universe. The first approach is based on a cosmological model formulated and developed in the last ten years by the first and third authors of this paper; the so-called Archaic Universe. The second approach was formulated by Rosen in 1933 by considering the Friedmann-Einstein equations as a simple one-dimensional dynamical system reducing the cosmological equations in terms of a Schroedinger equation. As an example, the quantum memory in cosmological dynamics could explain the apparently periodic structures of the Universe while Archaic Universe shows how the quantum phase concernts not only an ancient era of the Universe, but quantum facets permeating the entire Universe today.Comment: 18 page

Calibration and correction of the BTVs images

As the screen at the BTV monitor is not orthogonal to the optical axis of the camera, the image acquired by the CCD results distorted. An algorithm to correct for this distortion and other orientation errors is described in this note

Relative entropy via non-sequential recursive pair substitutions

The entropy of an ergodic source is the limit of properly rescaled 1-block entropies of sources obtained applying successive non-sequential recursive pairs substitutions (see P. Grassberger 2002 ArXiv:physics/0207023 and D. Benedetto, E. Caglioti and D. Gabrielli 2006 Jour. Stat. Mech. Theo. Exp. 09 doi:10.1088/1742.-5468/2006/09/P09011). In this paper we prove that the cross entropy and the Kullback-Leibler divergence can be obtained in a similar way.Comment: 13 pages , 2 figure

LHC LEAD ION BEAM OPTICS WITH LOW-BETA INSERTION FOR THE PS TO SPS TRANSFER LINE

In the context of the LHC operation with lead ions programme, a low beta insertion was implemented in the PS to SPS transfer line TT2, for the stripping foil installation, in order to reduce the beam emittance blow-up at the foil to values consistent with the tight emittance budget of the LHC. Extra quadrupoles and power converters had to be installed in TT2, in order to obtain a satisfactorily low beta at the stripper location and a good quality matching of the line at the SPS injection. The performance of the new optics is discussed and measurements results in TT2 and in the SPS with the "early ion beam" are presented

Some aspects of the inertial spin model for flocks and related kinetic equations

In this paper, we study the macroscopic behavior of the inertial spin (IS) model. This model has been recently proposed to describe the collective dynamics of flocks of birds, and its main feature is the presence of an auxiliary dynamical variable, a sort of internal spin, which conveys the interaction among the birds with the effect of better describing the turning of flocks. After discussing the geometrical and mechanical properties of the IS model, we show that, in the case of constant interaction among the birds, its mean-field limit is described by a nonlinear Fokker-Planck equation, whose equilibria are fully characterized. Finally, in the case of non-constant interactions, we derive the kinetic equation for the mean-field limit of the model in the absence of thermal noise, and explore its macroscopic behavior by analyzing the mono-kinetic solutions

Urban transport management and customer perceived quality: a case study in the metropolitan area of Cagliari, Italy

Liberalization processes and the threats posed by ever increasing competition have forced public transport companies in Italy to pay a closer attention to their customers, so to enhance loyalty and demand for transport. These customer-targeted strategies have been responsible for some significant changes of otherwise consolidated practices, in an attempt to lure new transit riders and discourage potential competitors from entering local markets. The present study describes the results of an on-board survey implemented within the Cagliari’s metropolitan area and aimed at discovering the degree of perceived quality toward the offer of public transport managed by CTM S.p.A, the local transport agency in charge for the planning and management of public mobility around the Sardinian’ regional capital. The research focuses on the implementation of an Impact Score methodology which, following the suggestions included in the Transit Cooperative Research Program Report n°47 (1999), assesses the degree of perceived quality with reference to ten core attributes of the public transport. The survey results show a substantial lack of structural problems and a high level of perceived quality, although some attributes need to be addressed if CTM aims to preserve and strengthen the central role so far enjoyed
