Abitare nel reale. Dalla crisi della periferia alla tessitura di nuove relazioni contestuali
2019
I progetti redatti per “Palermo Sud-Est” sono il risultato di un Laboratorio di Laurea strutturatosi attraverso incontri, seminari, comunicazioni specialistiche, esposizioni critiche, che – in una strategia condivisa – ha visto ogni studente elaborare il proprio lavoro nel confronto con gli altri attori del Laboratorio stesso. La ricerca sui “progetti urbani” è stata impostata di modo che ogni laureando fosse messo a conoscenza dei progetti svolti nello stesso ambito territoriale dai colleghi che l’avevano preceduto, così da poter operare in continuità e contribuire a formulare un ragionamento unitario, nel quale ogni progetto costituisse continuazione, verifica o anche variante dei precede…

A Hybrid Power Supply with Variable Speed Drive for Automatically Move Irrigation Equipment: Margin of Feasibility
2021
Center pivot irrigation systems are widely used in agriculture. Their water pumping systems are primary energy consumers. The use of photovoltaic power plants and variable speed drives of electric motors can reduce energy costs. The purpose of this study is to determine the feasibility of integrating variable speed drives and photovoltaic modules into water pumping systems. A novel architecture of a pumping system was suggested. Its features are no battery backup and the sale of electricity into the grid.
Sistema di irrigazione a perno centrale
2021
L’invenzione consiste nell’impiego, nell’irrigazione pivot, dei comuni irrigatori rotanti che si utilizzano nei sistemi di irrigazione a pioggia (o per aspersione), che hanno il vantaggio, rispetto agli spruzzatori ed ai gocciolatori, di essere dotati di un ugello terminale di elevato diametro (4-30 mm). L’idea nasce quindi dalla ricerca di un sistema irriguo che conservi i benefici dell’irrigazione pivot (completa automatizzazione, manodopera limitata alla manutenzione degli apparecchi erogatori, elevata efficienza) e che al contempo rimuova del tutto il problema dell’occlusione degli apparecchi erogatori. Vengono così azzerati i costi di manodopera e, soprattutto, viene consentito l’impie…
Subtitling in the digital era: TV crime drama series in domestic languages
2022
This study is set within the context of extensive academic attention to and exploration of audio and visual data as resources, methods and practices in the Digital Humanities (henceforth DH) (Gallitelli 2016). DH are seen and understood as a large and heterogeneous container that accommodates different research areas and affects various media. It is a relatively young field of study, inextricably linked to the development of information technologies within which the audiovisual dimension plays a central role. Audiovisual texts as forms of knowing, learning and entertaining have recently achieved a strategic position in the field of DH alongside current advances in computing. The digital acc…
Iron(iii) oxamato-catalyzed epoxidation of alkenes by dioxygen and pivalaldehyde
1997
A new iron(III)–carbonato monomeric complex of orthophenylenebis( oxamato) (opba) 1 is synthesized, and spectroscopically and structurally characterized; it is a moderately efficient non-heme catalyst for the aerobic epoxidation of alkenes with co-oxidation of pivalaldehyde.

Posterior stability in posterior-stabilized vs medially congruent total knee replacement: A radiological comparison of two polyethylene designs in a …
2020
Objective:The purpose of this radiological study was to assess the posterior laxity of a single model of a total knee arthroplasty design (TKA) having a medially constrained (MC) or a Posterior-Stabilized (PS) polyethylene insert using a well-documented stress x-ray. To the authors knowledge, this is the first report evaluating MC TKA outcomes according to the “kneeling view.”Materials and Methods:Sixty patients with non-traumatic primary knee osteoarthritis undergoing TKA were first matched by age, sex, BMI and diagnosis and then divided in two groups: group A (37 knees) received a MC TKA and group B (23 knees) a PS implant made by the same manufacturer. In all cases the posterior cruciate…
Higher-order Nonnegative CANDECOMP/PARAFAC Tensor Decomposition Using Proximal Algorithm
2019
Tensor decomposition is a powerful tool for analyzing multiway data. Nowadays, with the fast development of multisensor technology, more and more data appear in higherorder (order > 4) and nonnegative form. However, the decomposition of higher-order nonnegative tensor suffers from poor convergence and low speed. In this study, we propose a new nonnegative CANDECOM/PARAFAC (NCP) model using proximal algorithm. The block principal pivoting method in alternating nonnegative least squares (ANLS) framework is employed to minimize the objective function. Our method can guarantee the convergence and accelerate the computation. The results of experiments on both synthetic and real data demonstrate …
