Out-of-equilibrium finite-size method for critical behavior analyses
No full textWe present a dynamic off-equilibrium method for the study of continuous transitions, which represents a dynamic generalization of the usual equilibrium cumulant method. Its main advantage is that critical parameters are derived from numerical data obtained much before equilibrium has been attained. Therefore, the method is particularly useful for systems with long equilibration times, like spin glasses. We apply it to the three-dimensional Ising spin-glass model, obtaining accurate estimates of the critical exponents and of the critical temperature with a limited computational effort

Dance in Attic and Argive Geometric Pottery: figurative Imagery and ritual Contexts
No full textAll'alba delle immagini nella ceramica geometrica greca, a partire all'incirca dalla metà dell'VIII sec. a.C., il tema della danza è spesso rappresentato come uno dei meccanismi centrali della comunità. Il presente articolo si focalizza sul ricco corpus di rappresentazioni della danza e della performance musicale sulla ceramica attica e argiva all'incirca dal 750 al 675 a.C. Per quanto concerne la ceramica attica, una prima fase di queste rappresentazioni (ca. 750-720 a.C.) si focalizza sul carattere iniziatico della danza, che prelude al matrimonio, e sui suoi aspetti agonali. Una fase successiva, del 720-675 a.C. ca., si concentra sui choroi di parthenoi che erano educate nel sistema della polis. Queste ultime scene sembrano anticipare, nel dualismo tra il choròs di adolescenti e il musicista/corego, i meccanismi dei partenii, che sono noti a partire dai componimenti del poeta Alcmane. Le rappresentazioni argive si focolizzano sul carattere pre-nuziale della danza, con possibili riferimenti ai rituali dell'iniziazione durante le feste in onore di Hera. In generale il tema della danza nella ceramica geometrica pone l'accento sul mondo femminile, con riferimento alle classi di età, all'educazione, al preludio al matrimonio, così come alle componenti agonali.At the dawn of the images in Greek Geometric pottery, starting from ca. the middle of the 8th century BC, the theme of the dance is often represented as one of the community’s central mechanism. The present article focuses on the rich corpus of representations of dance and musical performance on Attic and Argive pottery from ca. 750 until 675 BC. On Attic pottery an early phase of these representations (ca. 750-720 BC) focuses on the initiatory character of dance, which preludes to the marriage, and on its agonistic aspects. The later phase, ca. 720-675 BC, shifts on the choroi of parthenoi which were educated in the system of the polis. These latter scenes seem to anticipate, in the dualism between the choros of adolescents and the musician/choregos, the mechanisms of the partheneia, that are known by Alcman’s compositions onwards. Argive representations focus on the prenuptial character of the dance, possibly with reference to the rituals of initiation during Hera’s festivals. In general, the theme of dance in Greek Geometric pottery draws the attention to the world of the females with reference to the class ages, the education, the prelude of the marriage as well as the agonistic components
NG-DBSCAN: Scalable Density-Based Clustering for Arbitrary Data
No full textWe present NG-DBSCAN, an approximate density-based clustering
algorithm that operates on arbitrary data and any symmetric
distance measure. The distributed design of our algorithm makes it
scalable to very large datasets; its approximate nature makes it fast,
yet capable of producing high quality clustering results. We provide
a detailed overview of the steps of NG-DBSCAN, together
with their analysis. Our results, obtained through an extensive experimental
campaign with real and synthetic data, substantiate our
claims about NG-DBSCAN’s performance and scalability
TUTELA DEL LAVORO E LIBERTA' D'IMPRESA NEI PROCESSI DI ESTERNALIZZAZIONE
No full textL’elaborato analizza le conseguenze lavoristiche della successione fra imprenditori, muovendo da una ricognizione delle varie tipologie di esternalizzazione con le relative esigenze e principali criticità.
L’indagine si concentra in primo luogo sul trasferimento d’azienda, esaminando la normativa e la giurisprudenza europee per passare poi alla disciplina di diritto interno, alle procedure sindacali e a uno specifico focus sul trasferimento delle aziende in crisi.
Successivamente l’autore si sofferma sull’appalto, prendendone in particolare considerazione gli indici di genuinità, i criteri di distinzione dalla somministrazione illecita di manodopera e la tutela delle maestranze in caso di avvicendamento fra imprese.
Da ultimo, la ricerca approfondisce le c.d. “clausole sociali”, sia di prima che di seconda generazione, valutandone la compatibilità con il diritto eurounitario e con la costituzione nonché riflettendo sui possibili rimedi in caso di loro violazione.The author analyzes the labour consequences of the succession between entrepreneurs, starting from a recognition of the various types of outsourcing with the related needs and main critical issues.
The survey focuses primarily on the transfer of businesses, examining European legislation and case-law and then moving on to internal legislation, trade union procedures and a specific focus on the transfer of companies in crisis.
The author then dwells on the contract, taking into account in particular the indications of authenticity, the criteria of distinction from the illicit administration of labour and the protection of workers in the event of turnover between companies.
Finally, the research deepens the "social clauses", both first and second generation, assessing their compatibility with European law and with the constitution and reflecting on possible remedies in case of their violation
Metastability at the Yield-Stress Transition in Soft Glasses
No full textWe study the solid-to-liquid transition in a two-dimensional fully periodic soft-glassy model with an imposed spatially heterogeneous stress. The model we consider consists of droplets of a dispersed phase jammed together in a continuous phase. When the peak value of the stress gets close to the yield stress of the material, we find that the whole system intermittently tunnels to a metastable “fluidized” state, which relaxes back to a metastable “solid” state by means of an elastic-wave dissipation. This macroscopic scenario is studied through the microscopic displacement field of the droplets, whose time statistics displays a remarkable bimodality. Metastability is rooted in the existence, in a given stress range, of two distinct stable rheological branches, as well as long-range correlations (e.g., large dynamic heterogeneity) developed in the system. Finally, we show that a similar behavior holds for a pressure-driven flow, thus suggesting possible experimental tests
Ultra Low Carbon Vehicles: New Parameters for Automotive Design
No full textAs the influence of vehicle emissions on our environment has become better understood, the UK government has recently placed urgent emphasis on the implementation of low carbon
technologies in the automotive industry through: the UK Low Carbon Industrial Strategy. The overall objective is to offer big incentives to consumers and support for the development of infrastructure and engineering solutions. This scheme however does not consider how the development of functional and experiential user value might drive consumer demand, contributing to the adoption of low carbon vehicles (LCVs) in the mass market.
With the emergence of the North East of England as the UK’s first specialised region for the development of ultra-low carbon vehicles (ULCVs), ONE North East, as a development agency for the region's economic and business development, and Northumbria University Ideas-lab have supported a project to facilitate innovation through the collaboration of technology, research and development (R&D) and business. The High Value Low Carbon (HVLC) project aims to envisage
new user value made possible by the integration of low carbon vehicle platforms with new process and network technologies. The HVLC consortium represents vehicle manufacturers and their suppliers as well as technology based companies and through an ongoing process of design concept generation the project offers a hub for innovation led enterprise.
Whilst new technological developments in areas such as power generation, nano materials, hydrogen fuel cells, printed electronics and networked communications will all impact on future automotive design, the mass adoption of low carbon technologies represents a paradigm shift for the motorist. This paper aims to describe how the mapping of new parameters will lead to new transport scenarios that will create the space for new collaborative research on user experiences supported by innovative technologies and related services
