The structures formation of the Universe appears as if it were a classically self-similar random process at all astrophysical scales. An agreement is demonstrated for the present hypotheses of segregation with a size of as-trophysical structures by using a comparison between quantum quantities and astrophysical ones. We present the observed segregated(More)
The long–standing issues of determination of the mass distribution and nature of the center of our Galaxy could be probed by a lensing experiment capable of testing the spatial and velocity distributions of stars nearby and beyond it. We propose a lensing toy–model which could be a further evidence that a massive consensation (e.g. a neutrino condensation)(More)
The paper deals with classical problem for cracks dislocated in a certain very specific porous elastic material, described by a Cowin-Nunziato model. We propose a method based upon a reducing of stress concentration problem for cracks to some integral equations. By applying Fourier integral transforms the problem is reduced to some integral equations. For(More)
In this paper we present a treatment of hypersingular integral equations , which have relevant applications in many problems of wave dynamics , elasticity and fluid mechanics with mixed boundary conditions. The main goal of the present work is the development of an efficient direct numerical collocation method. The paper is completed with two examples taken(More)
– The aim of this paper is to study the spatial behaviour of the solutions to the boundary–final value problems associated with the linear theory of elastic materials with voids. More precisely the present study is devoted to porous materials with a memory effect for the intrinsic equilibrated body forces. An appropriate time–weighted volume measure is(More)
Pixel lensing is a technique used to search for baryonic components of dark matter (MACHOs) and allows to detect microlensing events even when the target galaxies are not resolved into individual stars. Potentially, it has the advantage to provide higher statistics than other methods but, unfortunately, traditional approaches to pixel lensing are very(More)
Pixel lensing is a technique for searching baryonic components of dark matter, (MACHOs), in any part of galaxies. This method is very efficient, since it avoids to resolve each source star and so it has the advantage to provide an high statistic. Taking into account the fact that this technique is very time expensive in data analysis phase and the present(More)
SLOTT-AGAPE (Systematic Lensing Observation at Toppo Telescope-Andromeda Gravitational Amplification Pixel Lensing Experiment) is a new collaboration project among international partners from England, France, Germany, Italy and Switzerland that intends to perform mi-crolensing observation by using M31 as target. The MACHOs search is made thanks to the pixel(More)
