Dimensione abitativa dei migranti e luoghi d'interazione a Mazara del Vallo

2013

La mancata integrazione dei migranti è percepita come uno dei molteplici rischi cui è esposta la società postmoderna, generando insicurezza, inospitalità ed esclusione. Le maggioranze si sentono minacciate dalle minoranze (Bauman, 2000), sebbene la democrazia implichi l’ampliamento del consenso sui diritti dei gruppi minoritari. Comunità migranti d’altro canto, pur interagendo con le maggioranze, assumono comportamenti di difesa rispetto al tentativo di conformare le differenze culturali ai modelli prevalenti o dominanti. Tali considerazioni, che si rispecchiano nell’uso dello spazio urbano (i luoghi dell’abitare, del lavoro, del commercio e dei servizi) e raramente negli strumenti di piani…

An Advanced Technique for User Identification Using Partial Fingerprint

2013

User identification is a very interesting and complex task. Invasive biometrics is based on traits uniqueness and immutability over time. In forensic field, fingerprints have always been considered an essential element for personal recognition. The traditional issue is focused on full fingerprint images matching. In this paper an advanced technique for personal recognition based on partial fingerprint is proposed. This system is based on fingerprint local analysis and micro-features, endpoints and bifurcations, extraction. The proposed approach starts from minutiae extraction from a partial fingerprint image and ends with the final matching score between fingerprint pairs. The computation o…

Mobilità urbana e topografia: quattro progetti per Petralia Sottana

2013

Urban mobility and topography:four projects for Petralia Sottana. Many villages on the Madonie mountains share some material and non-material conditions: a complex articulation of the territorial altimetry,which often generates extraordinary landscape sites; a widespread population decrease (up to 50% in the last decades); the increasing relocation of inhabitants from the historical centre to peripheral areas; the difficult conciliation of both private and public traffic with the historical urban context; a deficit in the natural cycle of substitution and renovation of historical buildings and of public spaces. Four urban projects have been elaborated by the department of Architecture of Pa…

A heuristic for problem formalization in agent based simulation studies

2015

Agent Based Modeling and Simulation (ABMS) is considered an effective approach for conducting simulation studies in many fields. In order to develop high quality simulation models, methodological approaches are demanded. In such direction we are moving by proposing a heuristic for the formalization of agent based simulation problems. The proposed heuristic is based on some guidelines developed for identifying the main elements of the problem domain description by analysing verbs and their common taxonomy in grammar.

Computational Identification of Chemical Compounds with Potential Activity against Leishmania amazonensis using Nonlinear Machine Learning Techniques.

2019

Leishmaniasis is a poverty-related disease endemic in 98 countries worldwide, with morbidity and mortality increasing daily. All currently used first-line and second-line drugs for the treatment of leishmaniasis exhibit several drawbacks including toxicity, high costs and route of administration. Consequently, the development of new treatments for leishmaniasis is a priority in the field of neglected tropical diseases. The aim of this work is to develop computational models those allow the identification of new chemical compounds with potential anti-leishmanial activity. A data set of 116 organic chemicals, assayed against promastigotes of Leishmania amazonensis, is used to develop the the…

A satellite stand-alone procedure for deriving net radiation by using SEVIRI and MODIS products

2018

Abstract In this study, a new stand-alone satellite approach for the estimation of net surface radiation (Rn) has been implemented and validated for the Italian territory. The method uses the MODIS and MSG-SEVIRI time series products and it is independent of the use of ancillary data (i.e. ground measurements). A database of daily measurements of Rn, provided by 9 stations of the FLUXNET network, was used to validate the method in different ecological scenarios in the period 2010-12. The Rn modelled by the proposed approach and the corresponding FLUXNET measurements were in good agreement, with RMSE and R2 of 19.8 Wm−2 and 0.87, respectively, at 8-days scale, and 23.3 Wm−2 and 0.92, respect…

Artemisia arborescens L.: essential oil composition and effects of plant growth stage in some genotypes from Sicily

2012

Essential oils from aerial parts of several Artemisia arborescens L. populations, collected in five different localities of Sicily, were analyzed by gas chromatograph–flame ionization detector (GC–FID) and GC–mass spectrometry (GC–MS) in order to study the chemical composition and its variability due to phenological stage. Forty-three compounds, accounting for more than 92% of the oil, were identified. Monoterpene fraction with the exception of Petru population was higher than the sesquiterpene fraction. β-Thujone (20.5–55.9%), chamazulene (15.2–49.4%), camphor (1.3–10.7%) and germacrene D (2.3–3.4%) were the main compounds. Chemical composition was influenced by phenological stage, with an…

Le pieghe minori nelle Unità Imeresi e Trapanesi dei Monti di Palermo ed il loro significato nell’evoluzione tettonica dell’area

2003

In questo lavoro sono riassunte le osservazioni sulle pieghe minori che interessano i terreni delle Unità Imeresi e Trapanesi del settore orientale dei Monti di Palermo, con l'obbiettivo di: a) descri-vere la geometria e lo stile deformativo delle mesopieghe e stabilirne le relazioni spazio-temporali con le pieghe maggiori e le altre strut-ture minori (clivaggi, joints); b) ricavare, attraverso l'analisi stati-stica dei dati giaciturali, l'orientazione dei campi deformativi asso-ciati alle strutture plicative; c) ricostruire il significato delle pieghe minori nell'evoluzione tettonica dell'area. Nelle Unità Imeresi e Trapanesi, l'analisi statistica dei dati e le osservazioni di campagna han…
