Developing a Life Cycle Management methodology for road pavements
2022
The necessity of implementing sustainability is a main challenge in our society and it is taking up also in civil engineering works sector, although the infrastructure field is still understanding how to make the Sustainability Assessment (SA) a common practice within the National Road Authorities (NRAs). This research aims at providing a specific methodology for the Life Cycle Management (LCM) of road pavements materials and activities, starting from the available ISO and EN standards, by using Life-Cycle based techniques and Multi-Criteria Decision Making (MCDM), with the aim of assessing performance under the three pillars of sustainability.
A school trip and three modelling tasks. A experience in a secondary classroom
2015
[EN] This paper describes an experimence conducted in a ninth grade classroom. Three modeling tasks have been designed both related with the organization of a school trip. The main objective is to obtain the aspects to be considered when we propose this kind of tasks. For this aim we will analyze the result of experience thought the student’s responses in order to identify and classify the difficulties encountered them

La trilogia mondana di Girolamo Brusoni
1996
La monografia pone al centro dell'indagine la proposta modellizzante di una mondana perfezione, che è ricavabile dalla secentesca trilogia del Brusoni e appare il frutto di un preciso momento storico, in cui si dirada progressivamente l'atmosfera libertina che, pur con i suoi limiti, era stata alimentata dall'attività degli aderenti dell'Accademia degli Incogniti. Dal ciclo di Glisomiro, infatti, viene fuori un sistema comportamentale di particolare ampiezza e complessità, che non soltanto abbraccia le più esterne pratiche di relazione sociale, ma tocca l'indirizzo esistenziale. Mediante l'autobiografico protagonista, il Brusoni sperimenta un modello di comportamento, frutto sì di ammirata …

A Comprehensive Check of Usle-Based Soil Loss Prediction Models at the Sparacia (South Italy) Site
2020
At first, in this paper a general definition of the event rainfall-runoff erosivity factor for the USLE-based models, REFe = (QR)b1(EI30)b2, in which QR is the event runoff coefficient, EI30 is the single-storm erosion index and b1 and b2 are coefficients, was introduced. The rainfall-runoff erosivity factors of the USLE (b1 = 0, b2 = 1), USLE-M (b1 = b2 = 1), USLE-MB (b1 ≠ 1, b2 = 1), USLE-MR (b1 = 1, b2 ≠ 1), USLE-MM (b1 = b2 ≠ 1) and USLE-M2 (b1 ≠ b2 ≠ 1) can be defined using REFe. Then, the different expressions of REFe were simultaneously tested against a dataset of normalized bare plot soil losses, AeN, collected at the Sparacia (south Italy) site. As expected, the poorest AeN predict…
Il rilievo del sito archeologico di Eraclea Minoa: valutazioni metriche sull’impiego di un Sistema Aeromobile a Pilotaggio Remoto (SAPR)
2017
Il lavoro condotto ha affrontato le problematiche connesse con le fasi di acquisizione e elaborazione dei dati ottenuti da SAPR con la finalità di dimostrare il grande potenziale di questi sistemi per la fotogrammetria aerea di prossimità. Il lavoro ha previsto lo studio delle principali problematiche attraverso prove sperimentali condotte durante le fasi del rilievo del sito archeologico di Eraclea Minoa (Agrigento). In particolare, i dati acquisiti hanno permesso di analizzare in dettaglio le procedure di pianificazione ed esecuzione di voli e le procedure di orientamento in relazione anche alle metodologie di rilievo dei punti di appoggio. La fase di pianificazione del volo è stata studi…

Comparison between energy balance and mass balance models for actual evapotranspiration assessment
2009
The assessment of the water needs for a specific crop has a fundamental importance in the management of water resources. The application of empirical models able to retrieve estimates of the actual evapotranspiration (ETa) to assess the need for water could give a valid tool for the planning of water supply, avoiding unnecessary water losses. In this context, two independent models for estimating actual evapotranspiration were compared. The first model is based on an energy balance and uses remotely sensed data and ancillary data from weather stations to assess the ETa. The second model also uses remotely sensed data and climatic data on a daily basis from a weather network. Field measureme…
Predicting the equilibrium bed slope in natural streams using a stochastic model for incipient sediment motion
2011
In this paper, a method to predict the equilibrium bed slope in natural streams based on the incipient motion criterion is proposed. The method is based on the criterion suggested by Gessler to simulate the grain size distribution of the armour coat using the concept of critical shear stress of a sediment mixture. In particular, a different expression of the probability for a single particle size to be part of the armour coat is firstly proposed; then, a simple two-steps criterion is suggested to estimate the safety factor required by the proposed approach. The method is applied in three different Italian regions (Calabria, Basilicata, and Tuscany) and required several field campaigns invol…
