Soft Computing Methods for Personnel Selection Based on the Valuation of Competences

2014

Personnel selection based on candidates' competences is a difficult task due to the imprecise description of the applicants' competences and to the existence of several experts simultaneously evaluating those attributes. In this context, fuzzy sets theory provides suitable tools for the attainment of the maximum possible information from imprecise data. In this work, personnel selection methods are proposed that rely on the definition of an ideal candidate. Aggregated fuzzy valuations of each candidate are obtained taking into account the individual valuations provided by the experts. Then, candidates are ranked based on their similarity with the ideal candidate. Three different scenarios a…

Reducing complexity in H.264/AVC motion estimation by using a GPU

2011

H.264/AVC applies a complex mode decision technique that has high computational complexity in order to reduce the temporal redundancies of video sequences. Several algorithms have been proposed in the literature in recent years with the aim of accelerating this part of the encoding process. Recently, with the emergence of many-core processors or accelerators, a new approach can be adopted for reducing the complexity of the H.264/AVC encoding algorithm. This paper focuses on reducing the inter prediction complexity adopted in H.264/AVC and proposes a GPU-based implementation using CUDA. Experimental results show that the proposed approach reduces the complexity by as much as 99% (100x of spe…

Sorbus busambarensis (Rosaceae), a new endemic species of Sicily

2012

Abstract In this study, Sorbus busambarensis, a new species from Rocca Busambra (Palermo, NW Sicily) has been described and named. On the basis of the critical features of its flowers, fruits and leaves, it is noted to be a member of S. sect. Aria and is related to the other taxa that form the polymorphic group of S. aria, which in Sicily is represented by S. aria s. str., S. graeca and S. umbellata.

Clerodane diterpenoids from Salvia splendens.

2006

Four new clerodane diterpenoids, salvisplendins A-D (1-4), have been isolated from an acetone extract of the flowers of SalVia splendens, together with an artifact (5), arising from salvisplendin D (4) by addition of diazomethane, and the already known clerodane olearin (6). The structures of the new compounds (1-5) were established mainly by 1D and 2D NMR spectroscopic studies and, in the case of salvisplendin A (1), by chemical correlation with splenolide B (7). Complete 1H and 13C NMR assignments for olearin (6), not published hitherto, are also reported.

L'Elogio di Roma di Elio Aristide (or. XXVI K) - Storia della tradizione ed edizione critica

The purpose of the present thesis is to perform a research on the textual tradition and the critical edition of Aelius Aristides’ speech Εἰς Ῥώμην (To Rome) (2nd century CE). Delivered in Rome in 144 CE, this speech is a praise of the Roman Empire. The first critical edition of the speech was published by B. Keil in 1898; in the 20th century, two philologists prepared editions with critical text, based on the apparatus of Keil. The thesis consists of a general introduction and two parts, followed by the bibliography, and four appendices. The first part explains the research on the textual tradition of the speech, and is structured in six chapters. The second part consists of the critical ed…

Compared regimes of NDVI and Rainfall in semi-arid regions of Africa

2006

International audience; Bi-monthly normalized difference vegetation index (NDVI) at an 8km spatial resolution from the advanced very high resolution radiometers (AVHRR) was used from 1981 to 1995 to analyse the vegetation response to rainfall supply in semi-arid regions of Africa. Within the 200-600 mm annual rainfall belt, for which the apparent NDVI response to rainfall was the strongest, three regions were selected which exhibited different patterns in their NDVI regimes and/or relationships with rainfall. The regions, located in western, southern and eastern Africa, were split into coherent sub-regions in terms of mean regime of photosynthetic activity through a cluster analysis. Overal…

Sé, anima, corpo: Bruno Snell settant'anni dopo

2018

Prendendo come motivo occasionale il settantesimo anniversario dalla pubblicazione di un fortunato volume di Bruno Snell (Die Entdeckung des Geistes)l'autore passa in rassegna le principali teorie su sé, anima e corpo nella Grecia antica apparse nell'ultimo cinquantennio. Il problema della mente (incarnata o disincarnata?) si intreccia strettamente , nel dibattito, al problema sulla presenza o assenza di un dualismo mente/corpo. Il problema trova, a giudizio dell'autore, soluzione a partire dalle più recenti teorie sull'intelletto attivo di Aristotele.

Ne sub silentio spiritus relicto corpore exhalaret: lasciti e testamenti nella Sicilia medievale (XIV-XV secolo)

2012

Il saggio, attraverso l'esame di testamenti del XIV e XV secolo, illustra le motivazioni della diffusione della pratica testamentaria a partire dal XIV secolo e analizza le caratteristiche e le costanti dei testamenti dell'aristocrazia siciliana nel tardo Medioevo.

Il ruolo del white paper sulle offerte al pubblico di cripto-attività alla luce della proposta MiCA

2022

La proposta MiCA, nel regolare il white paper sulle offerte di crypto-assets, sembra tenere in considerazione i benefici e i limiti dei sistemi di voluntary e di mandatory disclosure, non optando integralmente né per il primo, né per il secondo. In quest’ottica, se può condividersi l’approccio regolamentare diretto a graduare, a seconda della tipologia di token offerto, sia il contenuto che l’assoggettamento del documento a mera notifica o ad approvazione ex ante da parte dell’Autorità competente, dubbi sorgono in ordine all’indistinta allocazione dell’onere della prova in capo all’oblato, nei casi di violazione della disciplina del relativo white paper.
