Impatti energetico-ambientali (e carbon footprint) del settore agroalimentare: il caso studio di tre prodotti siciliani

2017

La sostenibilità ambientale della filiera agro – alimentare è di primaria importanza per il raggiungimento degli obiettivi europei in tema di clima ed energia, considerato che il settore è responsabile di elevati consumi energetici e impatti ambientali. In tale contesto, nel presente lavoro è stata applicata la metodologia Life Cycle Assessment allo scopo di stimare gli impatti energetico – ambientali di tre tipologie di prodotti coltivati in aree di interesse naturalistico: la provola delle Madonie, il pane di Monreale e un olio monovarietale siciliano.

Usi pubblici e politici di Dante Alighieri

2022

The commemorations of Dante Alighieri ‘s 700th death anniversary saw in 2021 a ‘national’ and even a ‘nationalist ‘ Dante cropping up once again in the Italian public discourse. This article summarises the history of the public and political uses of the poet of the Divina Commedia: from the end of the 18th century, when his modern cult was born, to the Risorgimento, from the First World War to Fascism, up to the more recent ‘pop’ Dante.

Inclusive Design for Alzheimer’s Disease: Low-cost Treatments, Design and ICT

2019

Inability to acquire new memories, difficulty to remember recent events and to recognize objects, places and people, visual-spatial disorientation, these are some of the disorders with which who is affected by neurological diseases must learn to live with. In a continuously evolving society, where the decreasing birth rate and the drops in mortality are consistent, the job of Architecture is precisely to interpret the requirements and needs of people who have lost the canonical relationship with the world and give them the possibility to recover it or maintain it through communication channels that use their remaining ability to understand. The indoors and outdoors acquire a “prosthesis fun…

Hydrophilic primer has double the risk of bracket bond failure

2002

Question: In patients who need orthodontic bracketing is a hydrophilic primer or a conventional primer more effective for bonding? Objective To compare clinical failure rates of brackets bonded with a prototype hydrophilic primer and conventional primer. Design Randomised controlled trial (RCT) in a hospital setting. Intervention A split mouth design was used. Sides were randomly allocated to either hydrophilic (supplied by 3M Unitek (Monrovia, California, USA) or conventional primer (conventional TransbondTM 3M Unitek) adhesive), with the other side having alternative primer. Brackets were applied to 33 patients using a standard procedure. A total of 266 bonds were completed with each prim…

Toward a formalization of a two traders market with information exchange

2014

This paper shows that Hamiltonians and operators can also be put to good use even in contexts which are not purely physics based. Consider the world of finance. The work presented here {models a two traders system with information exchange with the help of four fundamental operators: cash and share operators; a portfolio operator and an operator reflecting the loss of information. An information Hamiltonian is considered and an additional Hamiltonian is presented which reflects the dynamics of selling/buying shares between traders. An important result of the paper is that when the information Hamiltonian is zero, portfolio operators commute with the Hamiltonian and this suggests that the dy…

First passage time distribution of stationary Markovian processes

2010

The aim of this paper is to investigate how the correlation properties of a stationary Markovian stochastic processes affect the First Passage Time distribution. First Passage Time issues are a classical topic in stochastic processes research. They also have relevant applications, for example, in many fields of finance such as the assessment of the default risk for firms' assets. By using some explicit examples, in this paper we will show that the tail of the First Passage Time distribution crucially depends on the correlation properties of the process and it is independent from its stationary distribution. When the process includes an infinite set of time-scales bounded from above, the FPT…

An efficient method for clustered multi-metric learning

2019

Abstract Distance metric learning, which aims at finding a distance metric that separates examples of one class from examples of the other classes, is the key to the success of many machine learning tasks. Although there has been an increasing interest in this field, learning a global distance metric is insufficient to obtain satisfactory results when dealing with heterogeneously distributed data. A simple solution to tackle this kind of data is based on kernel embedding methods. However, it quickly becomes computationally intractable as the number of examples increases. In this paper, we propose an efficient method that learns multiple local distance metrics instead of a single global one.…

Distributed Coverage of Ego Networks in F2F Online Social Networks

2016

Although most online social networks rely on a centralized infrastructure, several proposals of Distributed Online Social Networks (DOSNs) have been recently presented. Since in DOSNs user profiles are stored on the peers of the users belonging to the network, one of the main challenges comes from guaranteeing the profile availability when the owner of the data is not online. In this paper, we propose a DOSN based on a friend-to-friend P2P overlay where the user's data is stored only on friend peers. Our approach is based on the ego-network concept, which models the social network from the local point of view of a single user. We propose a distributed algorithm which is based on the notion …
