Opuntia cladodes as functional ingredient in durum wheat bread: rheological, sensory, and chemical characterization
2021
Cladodes are considered by-products of Opuntia ficus-indica cultivation. Their addition as source of antioxidants to durum wheat breads could have effects on preventing cardiovascular diseases, cancers, and inflammation. The inclusion of 0-5-10-15% cladodes, harvested in three different locations, on quality and antioxidant properties of fortified durum wheat breads has been evaluated. The enrichment with 10% of cladodes resulted in an increase in the content of total phenolics (14.8 vs 2.7 mg GAE/100 g of control bread), a decrease of IC50 (3.28 vs 49.7 mg/ml of control bread), good rheological characteristics of loaves and largely positive evaluation by panel test. Fortification with 15% …
COMPARISON BETWEEN VEHICLE SPEED PROFILES ACQUIRED BY DIFFERENTIAL GPS AND UAV
2014
Traffic microscopic simulation models are able to represent traffic conditions and their evolution over time. They take into account the geometrical aspects of transport infrastructures, driver behavior and, step by step, the vehicles’ movements on the road network. The most widespread applications of these models are referred to accident management, route guidance problems (possibility of evaluating control strategies in real time), adaptive control of traffic-light and ramp metering (management and control of the ramps and flow). To accomplish this goal observational data of vehicles’ kinematic characteristics have to be acquired. These elements are not always easily available. In scienti…
EVOLUZIONE DELLA COMPOSIZIONE GRANULOMETRICA DI SABBIE POMICEE SOTTOPOSTE A COMPRESSIONE 1-D FINO AD ALTE PRESSIONI
2012
Nell’articolo si riportano i risultati di uno studio sperimentale sull’evoluzione della composizione granulometrica di sabbie pomicee sottoposte a compressione 1-D fino a pressioni di 100 MPa. La sperimentazione è stata eseguita su sabbie asciutte con coefficiente di uniformità compreso tra 1.18 e 1.66 e con diametro iniziale dei grani compreso tra 0.18 e 2mm. Il crushing dei grani è significativo per tutte le granulometrie indagate a partire da pressioni efficaci basse (dell’ordine di appena 150 kPa). I risultati della ricerca dimostrano che, anche per queste sabbie dotate di un doppio ordine di pori – intergranulari e intragranulari - esiste una composizione granulometrica limite superior…
Properties of blended mortars produced with recycled by-products from different waste streams
2023
The construction industry encounters significant challenges in effectively managing solid waste produced during the extraction and production of building materials. In different countries, slurry waste generated from granite and marble processing industries, such as glass industry waste, constitutes a considerable portion of the total solid waste. Its undesirable disposal is causing unprecedented environmental damage. Using these non-biodegradable wastes to produce building materials would reduce the environmental burden and contribute to sustainable construction. This study, in detail, investigates the feasibility of utilizing Granite Powder (GP), Ground Granite Powder (GGP), and Ground Gl…
Masserie: Manor farms in Sicily. Typological characters, preservation and reuse
2018
The Sicilian land tenure was always characterized by the presence of latifundium. Such a land exploitation intimately influenced not only the farming techniques but also the population identity and farms’ typology. The Sicilian (and south-Italian) common typological form of rural estate is the masseria. More particularly, it is a large fortified farm built to control and manage a vast land-property, the old fiefdoms. This work focuses on the cultural and economic background, taking motion from the ancient feudality, that led to the construction and development of the masserie in Sicily. The typological characters, that deeply reflect the rural location and society, will be discussed: typolo…
I caratteri dell'architettura resiliente adattiva. Invarianti compositive del progetto: 1990-2020
2023
La Tesi di Dottorato “I caratteri dell’architettura resiliente adattiva. Invarianti compositive del progetto: 1990-2020” si propone di affrontare il rapporto fra l’architettura resiliente adattiva e le invarianti compositive del progetto attraverso l’influenza che tale rapporto ha sull’evoluzione e l’innovazione dei caratteri dell’architettura. In un momento storico in cui termini come resilienza e innovazione ricoprono un ruolo cruciale nell’esplorazione delle potenzialità della ricerca e costituiscono un requisito indispensabile per la programmazione del prossimo futuro, si è ritenuto opportuno ricondurre l’attenzione della ricerca dottorale al cuore della disciplina del progetto di archi…
EntityBot: Supporting Everyday Digital Tasks with Entity Recommendations
2021
Everyday digital tasks can highly benefit from systems that recommend the right information to use at the right time. However, existing solutions typically support only specific applications and tasks. In this demo, we showcase EntityBot, a system that captures context across application boundaries and recommends information entities related to the current task. The user’s digital activity is continuously monitored by capturing all content on the computer screen using optical character recognition. This includes all applications and services being used and specific to individuals’ computer usages such as instant messaging, emailing, web browsing, and word processing. A linear model is then …
Integration of a structural features-based preclassifier and a man-machine interactive classifier for a fast multi-stroke character recognition
2003
A transputer-based parallel machine for handwritten character recognition is proposed. An algorithm based on structural features and on a tree classifier was used to accomplish the pre-classification of the unknown sample in order to speed up the recognition process. The algorithm for the final classification is based on the description of the strokes through Fourier descriptors. The learning phase is accomplished through a man-machine interactive process. The proposed system can expand its knowledge base. A special representation of this knowledge base is proposed in order to record a great amount of data in a suitable way. A fast multistroke handwritten isolated character recognition syst…
An improved five-parameter model for photovoltaic modules
2010
This paper presents a new five-parameter model capable of analytically describing the I–V characteristic of a photovoltaic module for each generic condition of operative temperature and solar irradiance. The parameters of the equivalent electrical circuit are extracted by solving a system of equations based on data commonly issued by manufacturers in standard rating conditions with a trial and error process. The procedure, which does not require any special equations solver, can be easily coded into a short software routine using simple languages and finds the solution of the system of equations with the desired accuracy without needing to be guided towards solutions starting from fitted in…
STUDIO DI UNA FRIZIONE MAGNETOREOLOGICA PER AUTOVEICOLI
2013
Dopo un’accurata ricerca bibliografica sui fluidi magnetoreologici, il loro comportamento ed impiego, si è passati alla progettazione di una frizione magnetoreologica per autoveicoli. Considerando le caratteristiche di coppia trasmessa e potenza, il dispositivo è stato dimensionato tenendo presente i vincoli di ingombro del veicolo preso in esame. Sottoponendo il dispositivo ad analisi magnetostatica agli elementi finiti, si è determinato l’andamento delle linee di flusso del campo magnetico nel meato di fluido e nelle zone di maggior interesse, calcolando la coppia teoricamente trasmessa dall’innesto.È stato anche eseguito il confronto delle prestazionifra una frizione MR ed una frizione t…
