Influence of Geometrical Parameters, Wall Angle and Part Shape on Thickness Reduction of Single Point Incremental Forming
2014
Abstract The aim of this paper is to study the thickness reduction during the whole single point incremental forming process. The experimental setup is realized in such a way that the blank sheet is in the vertical position and forming is done using an anthropomorphic robot with six degrees of freedom. The vertical positioning of the blank sheet allows the on-line visualization using an optical measuring system of the major and minor strains and of the thickness reduction. The wall angle varied between values of 45 0 , 55 0 and 65 0 respectively. The logarithmic major strain and minor strains and logarithmic thickness reduction were analyzed in order to allow a comparison with values obtain…
Energy-weighted M1 sum rule with explicit δ degrees of freedom
1985
Abstract The influence of Δ degrees of freedom on the energy-weighted M1 sum rule is investigated and applied to 2 H and 4 He. Using π- and ρ-exchange potentials a reduction of the potential contribution of the order of 50% is obtained. The absolute value of the sum rule is strongly dependent on the short-range behaviour of the nuclear wave function. Furthermore, the contribution of c.m. effects is evaluated and found to be of the order of 5–10%.
Molecular mode-coupling theory applied to a liquid of diatomic molecules
2000
We study the molecular mode coupling theory for a liquid of diatomic molecules. The equations for the critical tensorial nonergodicity parameters ${\bf F}_{ll'}^m(q)$ and the critical amplitudes of the $\beta$ - relaxation ${\bf H}_{ll'}^m(q)$ are solved up to a cut off $l_{co}$ = 2 without any further approximations. Here $l,m$ are indices of spherical harmonics. Contrary to previous studies, where additional approximations were applied, we find in agreement with simulations, that all molecular degrees of freedom vitrify at a single temperature $T_c$. The theoretical results for the non ergodicity parameters and the critical amplitudes are compared with those from simulations. The qualitat…
La libertà di stampa e il diritto all'oblio nei casi di diffusione di articoli attraverso internet: argomenti comparativi
2013
L’evoluzione tecnologica ha determinato dei rapidi cambiamenti per la protezione dei dati personali, dovuti alla capacità del web di conservare informazioni facilmente accessibili da tutti. L’idoneità di Internet a svolgere adeguatamente la funzione di archivio è quindi un tema particolarmente attuale. Scopo del presente lavoro è stato di esaminare, a scopo comparativo, il recente orientamento giurisprudenziale in tema di libertà di stampa e di diritto all’oblio, prendendo come spunto la decisione della Corte di Strasburgo Węgrzynowski e Smolczewski c. Polonia. Si è, quindi, proceduto ad analizzare la giurisprudenza di tale Corte in materia di pubblicazioni elettroniche, per poi verificare …
Vulnerability, freedom of choice and structural global injustice: The “consent” to exploitation of migrant women workers
2019
This chapter analyzes the philosophical implications related to the “position of vulnerability” defined by the Directive 2011/36/EU on Preventing and Combating Trafficking in Human Beings and Protecting its Victims as “a situation in which the person concerned has no real or acceptable alternative but to submit to the abuse involved” (art. 2.2). In particular, the chapter focuses on the “choice” made by migrant women employed in care and domestic work and in the agricultural sector in Italy. The Italian labor market is marked by the exploitation of migrant women, especially women from Romania, due to social, economic and legal factors that will be considered from a gender perspective. Women…
Aging in a free-energy landscape model for glassy relaxation
2005
The aging properties of a simple free-energy landscape model for the primary relaxation in supercooled liquids are investigated. The intermediate scattering function and the rotational correlation functions are calculated for the generic situation of a quench from a high temperature to below the glass transition temperature. It is found that the re-equilibration of molecular orientations takes longer than for translational degrees of freedom. The time scale for re-equilibration is determined by that of the primary relaxation as an intrinsic property of the model.
Il dilemma sicurezza vs. libertà al tempo del terrorismo internazionale
2017
In Constitutional States security and individual freedom are often in conflict; in these last years, international terrorism, with its unpredictable attacks, has suggested a new way to guarantee the security of a community, even through the use of force. First of all, this contribution analyzes the meaning and the content of «security» (as a value, a principle, a right) according to the most important authors; the second section considers some of the most recent measures to prevent and combat terrorism adopted by the EU and some European States; some important reactions of national judges to protect individual rights will also be taken into account.
A single-domain Ritz approach for buckling and post-buckling analysis of cracked plates
2019
Abstract A Ritz approach for the analysis of buckling and post-buckling of plates with through-the-thickness cracks is presented. The plate behavior is described by the first order shear deformation theory and von Karman’s geometric nonlinearity. The admissible functions used in the displacements approximation are series of regular orthogonal polynomial supplemented with special functions able to decribe the dicontinuity across the crack and the singularity at the crack tips; boundary functions are used to fullfill the homogeneous essential boundary conditions. Convergence studies and analysis results are presented for buckling and post-buckling of plates with a central through-the-thicknes…
Il coordinamento tra gli articoli 8 e 10 CEDU in una recente pronuncia della Supreme Court inglese
2022
Lo scritto prende in considerazione il tema del possibile conflitto tra il dirit- to al rispetto della vita privata sancito dall’art. 8 CEDU e la libertà di espressio- ne riconosciuta dall’art. 10 della stessa Convenzione. L’indagine viene condotta traendo spunto da una recente sentenza della Supreme Court inglese nel caso Bloomberg in cui si dibatteva circa la liceità della pubblicazione della notizia dell’esistenza di indagini riguardanti il dirigente di una società, prima ancora e senza che nei suoi confronti fosse stata ufficialmente formulata alcuna ac- cusa penalmente rilevante. La risposta negativa in tutti e tre i gradi del giu- dizio, in cui fu accertata l’esistenza del diritto del…
La lunga marcia verso la libertà sindacale del “comparto sicurezza”
2020
Il saggio analizza l’evoluzione dei diritti sindacali nel “comparto sicurezza” (forze armate e di polizia) all’insegna di una prospettiva multilivello: dopo una disamina delle fonti sovranazionali (convenzioni OIL, Cedu e Carta Sociale Europea) e del dettato costituzionale, la ricerca si sofferma sulla libertà sindacale di militari e poliziotti alla luce del quadro normativo e giurisprudenziale di riferimento. Nonostante dal finire degli anni ’70 l’ordinamento militare e quello della Polizia di Stato si siano progressivamente aperti ai diritti collettivi, permangono numerosi profili di criticità, come il regime di separatezza sindacale, il divieto di sciopero e la mancata emanazione di una …
