The societal impact of traffic is a long-standing and complex problem. We focus on the estimation of ground-level ozone production due to vehicular traffic. We propose a comprehensive computational approach combining four consecutive modules: a traffic simulation module, an emission module, a module for the main chemical reactions leading to ozone production, and a module for the diffusion of gases in the atmosphere. The traffic module is based on a second-order traffic flow model, obtained by choosing a special velocity function for the Collapsed Generalized Aw-Rascle-Zhang model. A general emission module is taken from literature, and tuned on NGSIM data together with the traffic module. Last two modules are based on reaction-diffusion partial differential equations. The system of partial differential equations describing the main chemical reactions of nitrogen oxides presents a source term given by the general emission module applied to the output of the traffic module. We use the proposed approach to analyze the ozone impact of various traffic scenarios and describe the effect of traffic light timing. The numerical tests show the negative effect of vehicles restarts on emissions, and the consequent increase in pollutants in the air, suggesting to increase the length of the green phase of traffic lights.

Il report fornisce una panoramica del Fondo Europeo per lo Sviluppo Regionale, particolarmente nel Programma Operativo Regionale del Lazio, a partire dalla Strategia Europa 2020 (obiettivi, iniziative faro, principi di programmazione) e dai fondi strutturali UE (tipologia, principi orizzontali, quadro strategico comune, programmi operativi nazionali e gestione dei fondi), delineandone obblighi di informazione e pubblicità.

The aim of this preliminary study is to understand and simulate the hydric behaviour of a porous material in the presence of protective treatments. In particular, here the limestone Lumaquela deAjarte is considered before and after the application of the silane-based product ANC. A recently developed mathematical model was applied in order to describe the capillary rise of water in stone specimens. The model was calibrated by using experimental data concerning the water absorption by capillarity in both treated and untreated stone specimens. With a suitable calibration of the main parameters of the model and of the boundary conditions, it was possible to reproduce the main features of the experimentally observed phenomenon.

The impact of vehicular traffic on society is huge and multifaceted, including economic, social, health and environmental aspects. The problems is complex and hard to model since it requires to consider traffic patterns, air pollutant emissions, and the chemical reactions and dynamics of pollutants in the low atmosphere. This paper aims at exploring a comprehensive simulation tool ranging from vehicular traffic all the way to environmental impact. As first step in this direction, we couple a traffic second-order model, tuned on NGSIM data, with an nitrogen oxides (NO) emission model and a set of equations for some of the main chemical reactions behind ozone (O) production.

[object Object]Metals, extensively used in technology applications as well as in art metal works, have a chemical affinity for oxygen, water, sulphur and are particularly susceptible to electrochemical processes due to the environment. For this reason the monitoring of the effect of environmental conditions (temperature, humidity, pollutant concentration) on their mechanical and physical properties are considered a primary necessity for metal conservation and preservation. The complexity of the degradation phenomena requires to develop predictive tools, able to simulate involved chemical processes. In the present work a mathematical model, based on partial differential equation, is proposed. The model describes the evolution of corrosion processes, which occur on copper-tin alloy specimens exposed to sulphur dioxide atmosphere (SO 2 ).

In this paper some recent mathematical models applied to material damage are reviewed. The complexity of damage processes related to Cultural Heritage materials creates the necessity of developing predictive tools in order to monitor and detect surface alterations even before they are visible by naked eyes. The proposed models, elaborated by a research group of the Institute of Applied Mathematics - Research Council of Italy, are based on partial differential equations and well capture the main features of chemical processes (copper corrosion and salt crystallization), which occur on different materials such as stone and copper.

A new partial differential model for monitoring and detecting copper corrosion products (mainly brochantite and cuprite) is proposed to provide predictive tools suitable for describing the evolution of damage induced on bronze specimens by sulfur dioxide (SO2) pollution. This model is characterized by the movement of a double free boundary. Numerical simulations show a nice agreement with experimental result. (C) 2014 Elsevier Inc. All rights reserved.
