Supply chain management allows companies to look beyond their organizational boundaries to develop and leverage resources and capabilities of their supply chain partners. This leads to create competitive advantages in the marketplace and because of this SCM has acquired strategic importance. Lean Approach is a management strategy that focuses on reducing every type of waste present in an organization. This approach is becoming more and more popular among supply chain managers. The supply chain application of lean approach is low diffused. It is not well studied which are the impacts of lean approach principles in a supply chain context. In literature there are only few studies simulating the lean approach performance in single products supply chain. This research work studies the impacts of lean principles implementation along a supply chain. To achieve this, a simulation model of a three-echelon multiproduct product supply chain has been built. Kanban system (and several priority policies) and setup time reduction degrees are implemented in the lean-configured supply chain to apply pull and lot-sizing decrease principles respectively. To evaluate the benefits of lean approach, lean supply chain is compared with an EOQ-configured supply chain. The simulation results show that Kanban system and setup-time reduction improve inventory stock level. They also show that logistics efforts are affected to lean implementation degree. The paper concludes describing performances of lean supply chain in different contexts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inventory%20policy" title="inventory policy">inventory policy</a>, <a href="https://publications.waset.org/abstracts/search?q=Kanban" title=" Kanban"> Kanban</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20supply%20chain" title=" lean supply chain"> lean supply chain</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation%20study" title=" simulation study"> simulation study</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain%20management" title=" supply chain management"> supply chain management</a>, <a href="https://publications.waset.org/abstracts/search?q=planning" title=" planning"> planning</a> </p> <a href="https://publications.waset.org/abstracts/32262/simulation-of-lean-principles-impact-in-a-multi-product-supply-chain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32262.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">357</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> Uncertainty of the Brazilian Earth System Model for Solar Radiation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elison%20Eduardo%20Jardim%20Bierhals">Elison Eduardo Jardim Bierhals</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudineia%20Brazil"> Claudineia Brazil</a>, <a href="https://publications.waset.org/abstracts/search?q=Deivid%20Pires"> Deivid Pires</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafael%20Haag"> Rafael Haag</a>, <a href="https://publications.waset.org/abstracts/search?q=Elton%20Gimenez%20Rossini"> Elton Gimenez Rossini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study evaluated the uncertainties involved in the solar radiation projections generated by the Brazilian Earth System Model (BESM) of the Weather and Climate Prediction Center (CPTEC) belonging to Coupled Model Intercomparison Phase 5 (CMIP5), with the aim of identifying efficiency in the projections for solar radiation of said model and in this way establish the viability of its use.

This would ensure a faster assessment of the impacted barrier and subsequently facilitates the implementation of remedial works in an effective and timely manner. In addition, the HelloMac can also be integrated with another warning system to alert vehicle users of the unseen dangers ahead. HelloMac is developed to work also in remote areas, where cell coverage is not available. User gets notified when a rockfall even occurs via mobile app, SMS and email.

Drawing from cognitive semantics theories, image schemas and metaphors, it was attempted to demonstrate that: a) the metaphorical senses of both 'come out' and 'take over' extend from both the verbs and the particles central (spatial) senses in such verb combinations; and b) the particles 'out' and 'over' also contribute to the whole meaning of the verb combinations. In order to do so, a random selection of 579 concordance lines for come out and 1,412 for take over was obtained from the Corpus of Contemporary American English – COCA. One of the main procedures adopted in the present work was the establishment of verb and particle central senses. As per the research questions addressed in this study, they are as follows: a) how does the identification of trajector and landmark help reveal patterns that contribute for the identification of the semantic network of these two verb combinations?; b) what is the relationship between the schematic structures attributed to the particles and the metaphorical uses found in empirical data?; and c) what conceptual metaphors underlie the mappings from the source to the target domains? The results demonstrated that not only the lexical verbs come and take, but also the particles out and over play an important whole in the different meanings of come out and take over. Besides, image schemas and conceptual metaphors were found to be helpful in order to establish the motivations for the metaphorical uses of these linguistic structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cognitive%20linguistics" title="cognitive linguistics">cognitive linguistics</a>, <a href="https://publications.waset.org/abstracts/search?q=English%20syntax" title=" English syntax"> English syntax</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-word%20verbs" title=" multi-word verbs"> multi-word verbs</a>, <a href="https://publications.waset.org/abstracts/search?q=prepositions" title=" prepositions"> prepositions</a> </p> <a href="https://publications.waset.org/abstracts/88432/a-cognitive-semantic-analysis-of-the-metaphorical-extensions-of-come-out-and-take-over" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88432.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">155</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Study of Nanocrystalline Scintillator for Alpha Particles Detection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azadeh%20Farzaneh">Azadeh Farzaneh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Reza%20Abdi"> Mohammad Reza Abdi</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Quaranta"> A.

The structural properties of CsI nanoparticles were characterized by X-ray diffraction and Scanning Electron Microscope (SEM) Also, optical properties were followed by optical absorption and UV–vis fluorescence. Intense photoluminescence is also observed, with some spectral tuning possible with ripening time getting a range of emission photon wavelength approximately from 366 to 350 nm. The size effect on CsI luminescence leads to an increase in scintillation light yield, a redshift of the emission bands of the on_center and off_center self_trapped excitons (STEs) and an increase in the contribution of the off_center STEs to the net intrinsic emission yield. The energy transfer from the matrix to CsI nanoparticles is a key characteristic for scintillation detectors. So the scintillation spectra to alpha particles of sample were monitored. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanoparticles" title="nanoparticles">nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=luminescence" title=" luminescence"> luminescence</a>, <a href="https://publications.waset.org/abstracts/search?q=sol%20gel" title=" sol gel"> sol gel</a>, <a href="https://publications.waset.org/abstracts/search?q=scintillator" title=" scintillator"> scintillator</a> </p> <a href="https://publications.waset.org/abstracts/57403/study-of-nanocrystalline-scintillator-for-alpha-particles-detection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57403.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">599</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> A Sensitive Uric Acid Electrochemical Sensing in Biofluids Based on Ni/Zn Hydroxide Nanocatalyst</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nathalia%20Florencia%20Barros%20Azeredo">Nathalia Florencia Barros Azeredo</a>, <a href="https://publications.waset.org/abstracts/search?q=Josu%C3%A9%20%20Martins%20Gon%C3%A7alves"> Josué Martins Gonçalves</a>, <a href="https://publications.waset.org/abstracts/search?q=Pamela%20%20De%20Oliveira%20Rossini"> Pamela De Oliveira Rossini</a>, <a href="https://publications.waset.org/abstracts/search?q=Koiti%20Araki"> Koiti Araki</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucio%20%20Angnes"> Lucio Angnes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work demonstrates the electroanalysis of uric acid (UA) at very low working potential (0 V vs Ag/AgCl) directly in body fluids such as saliva and sweat using electrodes modified with mixed -Ni0.75Zn0.25(OH)2 nanoparticles exhibiting stable electrocatalytic responses from alkaline down to weakly acidic media (pH 14 to 3 range). These materials were prepared for the first time and fully characterized by TEM, XRD, and spectroscopic techniques. The electrochemical properties of the modified electrodes were evaluated in a fast and simple procedure for uric acid analyses based on cyclic voltammetry and chronoamperometry, pushing down the detection and quantification limits (respectively of 2.3*10-8 and 7.6*10-8 mol L-1) with good repeatability (RSD = 3.2% for 30 successive analyses pH 14). Finally, the possibility of real application was demonstrated upon realization of unexpectedly robust and sensitive modified FTO (fluorine doped tin oxide) glass and screen-printed sensors for measurement of uric acid directly in real saliva and sweat samples, with no significant interference of usual concentrations of ascorbic acid, acetaminophen, lactate and glucose present in those body fluids (Fig. 1). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nickel%20hydroxide" title="nickel hydroxide">nickel hydroxide</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20catalyst" title=" mixed catalyst"> mixed catalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=uric%20acid%20sensors" title=" uric acid sensors"> uric acid sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=biofluids" title=" biofluids"> biofluids</a> </p> <a href="https://publications.waset.org/abstracts/121329/a-sensitive-uric-acid-electrochemical-sensing-in-biofluids-based-on-nizn-hydroxide-nanocatalyst" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121329.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">127</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> A Combinatorial Representation for the Invariant Measure of Diffusion Processes on Metric Graphs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michele%20Aleandri">Michele Aleandri</a>, <a href="https://publications.waset.org/abstracts/search?q=Matteo%20Colangeli"> Matteo Colangeli</a>, <a href="https://publications.waset.org/abstracts/search?q=Davide%20%20Gabrielli"> Davide Gabrielli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We study a generalization to a continuous setting of the classical Markov chain tree theorem.

A metric arborescence is a metric tree oriented towards its root. The weight of each oriented metric arborescence is obtained by the product of the exponential of integrals of the form ∫a/b², where b is the drift and σ² is the diffusion coefficient, along the oriented edges, for a weight for each node determined by the local orientation of the arborescence around the node and for the inverse of the diffusion coefficient at x.

To diversify an energy matrix and to minimize global warming, a solar energy is gaining space, being an important source of renewable energy, and its potential depends on the climatic conditions of the region. Brazil presents a great solar potential for a generation of electric energy, so the knowledge of solar radiation and its characteristics are fundamental for the study of energy use. Due to the above reasons, this article aims to verify the climatic variability corresponding to the variations in solar radiation anomalies, in the face of climate change scenarios. The data used in this research are part of the Intercomparison of Interconnected Models, Phase 5 (CMIP5), which contributed to the preparation of the fifth IPCC-AR5 report. The solar radiation data were extracted from The Australian Community Climate and Earth System Simulator (ACCESS) model using the RCP 4.5 and RCP 8.5 scenarios that represent an intermediate structure and a pessimistic framework, the latter being the most worrisome in all cases. In order to allow the use of solar radiation as a source of energy in a given location and/or region, it is important, first, to determine its availability, thus justifying the importance of the study. The results pointed out, for the 75-year period (2026-2100), based on a pessimistic scenario, indicate a drop in solar radiation of the approximately 12% in the eastern region of Rio Grande do Sul. Factors that influence the pessimistic prospects of this scenario should be better observed by the responsible authorities, since they can affect the possibility to produce electricity from solar radiation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a>, <a href="https://publications.waset.org/abstracts/search?q=IPCC" title=" IPCC"> IPCC</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20radiation" title=" solar radiation"> solar radiation</a> </p> <a href="https://publications.waset.org/abstracts/79238/mapping-of-solar-radiation-anomalies-based-on-climate-change" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79238.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">192</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Predicting Machine-Down of Woodworking Industrial Machines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Matteo%20Calabrese">Matteo Calabrese</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Cimmino"> Martin Cimmino</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimos%20Kapetis"> Dimos Kapetis</a>, <a href="https://publications.waset.org/abstracts/search?q=Martina%20Manfrin"> Martina Manfrin</a>, <a href="https://publications.waset.org/abstracts/search?q=Donato%20Concilio"> Donato Concilio</a>, <a href="https://publications.waset.org/abstracts/search?q=Giuseppe%20Toscano"> Giuseppe Toscano</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Ciandrini"> Giovanni Ciandrini</a>, <a href="https://publications.waset.org/abstracts/search?q=Giancarlo%20Paccapeli"> Giancarlo Paccapeli</a>, <a href="https://publications.waset.org/abstracts/search?q=Gianluca%20Giarratana"> Gianluca Giarratana</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Siciliano"> Marco Siciliano</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Forlani"> Andrea Forlani</a>, <a href="https://publications.waset.org/abstracts/search?q=Alberto%20Carrotta"> Alberto Carrotta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper we describe a machine learning methodology for Predictive Maintenance (PdM) applied on woodworking industrial machines.

The proposed approach allows screening simultaneously multiple connected machines, thus providing real-time monitoring that can be adopted with maintenance management. This is achieved by applying temporal feature engineering techniques and training an ensemble of classification algorithms to predict Remaining Useful Lifetime of woodworking machines.

The use of various geosynthetic applications is very common these days for ground improvement. This paper presents a case study where the combination of two geosynthetic applications was used in order to optimize the design as well as to control the settlements through uniform load distribution. The Agartala-Akaura rail project was made to help increase railway connectivity between India and Bangladesh. Both countries have started the construction of the same. The project requires high railway embankments to be built for the rail link. However, the challenge was to design a proper ground improvement solution as the entire area comprises very soft soil for an average depth of 15m. After due diligence, a combination of two methods was worked out by Maccaferri. PVDs were provided for the consolidation, and on top of that, a layer of high-strength geogrids (Paralink) was proposed as a basal reinforcement. The design approach was followed as described in Indian standards as well as British standards. By introducing a basal reinforcement, the spacing of PVDs could be increased, which allowed quick installation and less material consumption while keeping the consolidation time within the project duration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ground%20improvement" title="ground improvement">ground improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=basal%20reinforcement" title=" basal reinforcement"> basal reinforcement</a>, <a href="https://publications.waset.org/abstracts/search?q=PVDs" title=" PVDs"> PVDs</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20strength%20geogrids" title=" high strength geogrids"> high strength geogrids</a>, <a href="https://publications.waset.org/abstracts/search?q=Paralink" title=" Paralink"> Paralink</a> </p> <a href="https://publications.waset.org/abstracts/181433/ground-improvement-with-basal-reinforcement-with-high-strength-geogrids-and-pvds-for-embankment-over-soft-soils" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181433.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">74</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> The Evaluation of Current Pile Driving Prediction Methods for Driven Monopile Foundations in London Clay</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=John%20Davidson">John Davidson</a>, <a href="https://publications.waset.org/abstracts/search?q=Matteo%20Castelletti"> Matteo Castelletti</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismael%20Torres"> Ismael Torres</a>, <a href="https://publications.waset.org/abstracts/search?q=Victor%20Terente"> Victor Terente</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamie%20Irvine"> Jamie Irvine</a>, <a href="https://publications.waset.org/abstracts/search?q=Sylvie%20Raymackers"> Sylvie Raymackers</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The current industry approach to pile driving predictions consists of developing a model of the hammer-pile-soil system which simulates the relationship between soil resistance to driving (SRD) and blow counts (or pile penetration per blow). The SRD methods traditionally used are broadly based on static pile capacity calculations. The SRD is used in combination with the one-dimensional wave equation model to indicate the anticipated blowcounts with depth for specific hammer energy settings. This approach has predominantly been calibrated on relatively long slender piles used in the oil and gas industry but is now being extended to allow calculations to be undertaken for relatively short rigid large diameter monopile foundations. This paper evaluates the accuracy of current industry practice when applied to a site where large diameter monopiles were installed in predominantly stiff fissured clay. Actual geotechnical and pile installation data, including pile driving records and signal matching analysis (based upon pile driving monitoring techniques), were used for the assessment on the case study site. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=driven%20piles" title="driven piles">driven piles</a>, <a href="https://publications.waset.org/abstracts/search?q=fissured%20clay" title=" fissured clay"> fissured clay</a>, <a href="https://publications.waset.org/abstracts/search?q=London%20clay" title=" London clay"> London clay</a>, <a href="https://publications.waset.org/abstracts/search?q=monopiles" title=" monopiles"> monopiles</a>, <a href="https://publications.waset.org/abstracts/search?q=offshore%20foundations" title=" offshore foundations"> offshore foundations</a> </p> <a href="https://publications.waset.org/abstracts/81659/the-evaluation-of-current-pile-driving-prediction-methods-for-driven-monopile-foundations-in-london-clay" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81659.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">224</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> IPO Valuation and Profitability Expectations: Evidence from the Italian Exchange</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Matteo%20Bonaventura">Matteo Bonaventura</a>, <a href="https://publications.waset.org/abstracts/search?q=Giancarlo%20Giudici"> Giancarlo Giudici</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper analyses the valuation process of companies listed on the Italian Exchange in the period 2000-2009 at their Initial Public Offering (IPO). One the most common valuation techniques declared in the IPO prospectus to determine the offer price is the Discounted Cash Flow (DCF) method. We develop a ‘reverse engineering’ model to discover the short term profitability implied in the offer prices. We show that there is a significant optimistic bias in the estimation of future profitability compared to ex-post actual realization and the mean forecast error is substantially large. Yet we show that such error characterizes also the estimations carried out by analysts evaluating non-IPO companies. The forecast error is larger the faster has been the recent growth of the company, the higher is the leverage of the IPO firm, the more companies issued equity on the market. IPO companies generally exhibit better operating performance before the listing, with respect to comparable listed companies, while after the flotation they do not perform significantly different in term of return on invested capital. Pre-IPO book building activity plays a significant role in partially reducing the forecast error and revising expectations, while the market price of the first day of trading does not contain information for further reducing forecast errors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=initial%20public%20offerings" title="initial public offerings">initial public offerings</a>, <a href="https://publications.waset.org/abstracts/search?q=DCF" title=" DCF"> DCF</a>, <a href="https://publications.waset.org/abstracts/search?q=book%20building" title=" book building"> book building</a>, <a href="https://publications.waset.org/abstracts/search?q=post-IPO%20profitability%20drop" title=" post-IPO profitability drop"> post-IPO profitability drop</a> </p> <a href="https://publications.waset.org/abstracts/21059/ipo-valuation-and-profitability-expectations-evidence-from-the-italian-exchange" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21059.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">352</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> Adoption and Diffusion of Valuation Standards in the Forensic Accounting Community and in Courts: Facilitating and Inhibiting Factors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Matteo%20Manera">Matteo Manera</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariateresa%20Torchia"> Mariateresa Torchia</a>, <a href="https://publications.waset.org/abstracts/search?q=Gregory%20Moscato"> Gregory Moscato</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Forensic accounting is a hot subject of research in accounting. Valuation remains one of the major topics for practitioners. Valuation standards are a powerful instrument that can contribute to a fair process: their use aims at reducing subjectivity and arbitrary decisions in courts. In most jurisdictions, valuation standards are not the law: forensic accountants are not obliged to use valuation standards when they perform valuation works for judges. To date, as far as we know, no literature work has investigated adoption and diffusion of valuation standards in the forensic accounting space. In this paper, we analyze the spread of valuation standards through the lenses of isomorphism and -as corollaries- of Agency Theory and Signaling Theory. Because of lack of research in the particular area of valuation standards adoption, the present work relies on qualitative, exploratory research, based on semi-structured interviews conducted (up to saturation) with expert forensic accountants. Our work digs into motivations behind adoption and diffusion, as well into perceptions of forensic accountants around benefits of valuation standards and into barriers to their diffusion: the result is that, while the vast majority of forensic accountants praise the great work of the standards setters in introducing valuation standards, it might be that less than 50% of forensic accountants actually use valuation standards, in courts. Our preliminary findings, to be supported or refuted by future research, lead us to address a “trilogy” of recommendations to the stakeholders involved in the process of adoption and diffusion of valuation standards in courts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forensic%20accounting" title="forensic accounting">forensic accounting</a>, <a href="https://publications.waset.org/abstracts/search?q=valuation%20standards" title=" valuation standards"> valuation standards</a>, <a href="https://publications.waset.org/abstracts/search?q=adoption%20of%20standards" title=" adoption of standards"> adoption of standards</a>, <a href="https://publications.waset.org/abstracts/search?q=motivations" title=" motivations"> motivations</a>, <a href="https://publications.waset.org/abstracts/search?q=benefits" title=" benefits"> benefits</a>, <a href="https://publications.waset.org/abstracts/search?q=barriers" title=" barriers"> barriers</a>, <a href="https://publications.waset.org/abstracts/search?q=Isomorphism" title=" Isomorphism"> Isomorphism</a> </p> <a href="https://publications.waset.org/abstracts/139052/adoption-and-diffusion-of-valuation-standards-in-the-forensic-accounting-community-and-in-courts-facilitating-and-inhibiting-factors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139052.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">172</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Path-Tracking Controller for Tracked Mobile Robot on Rough Terrain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Toshifumi%20Hiramatsu">Toshifumi Hiramatsu</a>, <a href="https://publications.waset.org/abstracts/search?q=Satoshi%20Morita"> Satoshi Morita</a>, <a href="https://publications.waset.org/abstracts/search?q=Manuel%20Pencelli"> Manuel Pencelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Marta%20Niccolini"> Marta Niccolini</a>, <a href="https://publications.waset.org/abstracts/search?q=Matteo%20Ragaglia"> Matteo Ragaglia</a>, <a href="https://publications.waset.org/abstracts/search?q=Alfredo%20Argiolas"> Alfredo Argiolas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Automation technologies for agriculture field are needed to promote labor-saving. One of the most relevant problems in automated agriculture is represented by controlling the robot along a predetermined path in presence of rough terrain or incline ground. Unfortunately, disturbances originating from interaction with the ground, such as slipping, make it quite difficult to achieve the required accuracy. In general, it is required to move within 5-10 cm accuracy with respect to the predetermined path. Moreover, lateral velocity caused by gravity on the incline field also affects slipping. In this paper, a path-tracking controller for tracked mobile robots moving on rough terrains of incline field such as vineyard is presented. The controller is composed of a disturbance observer and an adaptive controller based on the kinematic model of the robot. The disturbance observer measures the difference between the measured and the reference yaw rate and linear velocity in order to estimate slip. Then, the adaptive controller adapts “virtual” parameter of the kinematics model: Instantaneous Centers of Rotation (ICRs). Finally, target angular velocity reference is computed according to the adapted parameter. This solution allows estimating the effects of slip without making the model too complex. Finally, the effectiveness of the proposed solution is tested in a simulation environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=the%20agricultural%20robot" title="the agricultural robot">the agricultural robot</a>, <a href="https://publications.waset.org/abstracts/search?q=autonomous%20control" title=" autonomous control"> autonomous control</a>, <a href="https://publications.waset.org/abstracts/search?q=path-tracking%20control" title=" path-tracking control"> path-tracking control</a>, <a href="https://publications.waset.org/abstracts/search?q=tracked%20mobile%20robot" title=" tracked mobile robot"> tracked mobile robot</a> </p> <a href="https://publications.waset.org/abstracts/98362/path-tracking-controller-for-tracked-mobile-robot-on-rough-terrain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98362.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">172</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Electrospun Membrane doped with Gold Nanorods for Surface-Enhanced Raman Sepctroscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ziwei%20Wang">Ziwei Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Lucotti"> Andrea Lucotti</a>, <a href="https://publications.waset.org/abstracts/search?q=Luigi%20Brambilla"> Luigi Brambilla</a>, <a href="https://publications.waset.org/abstracts/search?q=Matteo%20Tommasini"> Matteo Tommasini</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiara%20Bertarelli"> Chiara Bertarelli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Surface-enhanced Raman Spectroscopy (SERS) is a highly sensitive detection that provides abundant information on low concentration analytes from various researching areas. Based on localized surface plasmon resonance, metal nanostructures including gold, silver and copper have been investigated as SERS substrate during recent decades. There has been increasing more attention of exploring good performance, homogenous, repeatable SERS substrates. Here, we show that electrospinning, which is an inexpensive technique to fabricate large-scale, self-standing and repeatable membranes, can be effectively used for producing SERS substrates. Nanoparticles and nanorods are added to the feed electrospinning solution to collect functionalized polymer fibrous mats. We report stable electrospun membranes as SERS substrate using gold nanorods (AuNRs) and poly(vinyl alcohol). Particularly, a post-processing crosslinking step using glutaraldehyde under acetone environment was carried out to the electrospun membrane. It allows for using the membrane in any liquid environment, including water, which is of interest both for sensing of contaminant in wastewater, as well as for biosensing. This crosslinked AuNRs/PVA membrane has demonstrated excellent performance as SERS substrate for low concentration 10-6 M Rhodamine 6G (Rh6G) aqueous solution. This post-processing for fabricating SERS substrate is the first time reported and proved through Raman imaging of excellent stability and outstanding performance. Finally, SERS tests have been applied to several analytes, and the application of AuNRs/PVA membrane is broadened by removing the detected analyte by rinsing. Therefore, this crosslinked AuNRs/PVA membrane is re-usable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SERS%20spectroscopy" title="SERS spectroscopy">SERS spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title=" electrospinning"> electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=crosslinking" title=" crosslinking"> crosslinking</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20materials" title=" composite materials"> composite materials</a> </p> <a href="https://publications.waset.org/abstracts/149036/electrospun-membrane-doped-with-gold-nanorods-for-surface-enhanced-raman-sepctroscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149036.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">140</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Exposure Assessment to Heavy Metals and Flame Retardants Among Moroccan Children and Their Impact on the Epigenetic Profile</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kaoutar%20Chbihi">Kaoutar Chbihi</a>, <a href="https://publications.waset.org/abstracts/search?q=Aziza%20Menouni"> Aziza Menouni</a>, <a href="https://publications.waset.org/abstracts/search?q=Emilie%20Hardy"> Emilie Hardy</a>, <a href="https://publications.waset.org/abstracts/search?q=Matteo%20Creta"> Matteo Creta</a>, <a href="https://publications.waset.org/abstracts/search?q=Nathalie%20Grova"> Nathalie Grova</a>, <a href="https://publications.waset.org/abstracts/search?q=An%20Van%20Nieuwenhuyse"> An Van Nieuwenhuyse</a>, <a href="https://publications.waset.org/abstracts/search?q=Lode%20Godderis"> Lode Godderis</a>, <a href="https://publications.waset.org/abstracts/search?q=Samir%20El%20Jaafari"> Samir El Jaafari</a>, <a href="https://publications.waset.org/abstracts/search?q=Radu-Corneliu%20Duca"> Radu-Corneliu Duca</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Industrial products and materials are often treated with additional compounds like brominated flame retardants (BFRs) and heavy metals in order to prevent their ignition, increase their functionality and improve their performance like electrical conductivity. Consequently, this could potentially expose children to harmful chemicals through indoor dust and through hand-to-mouth or toy-chewing behaviors. The aim of this study was to assess the exposure of Moroccan children aged 5-11 years to BFRs and heavy metal elements and investigate their impacts on the epigenetic profile, namely through global DNA methylation modifications. First, parents were asked to answer a questionnaire on children’s lifestyle, then blood and urine samples were collected from (n= 93) children, following the ethical guidelines, for biomonitoring and DNA methylation analysis, using a set of solid phase extraction (SPE), LC-MS/MS, GC-MS/MS and ICP/MS techniques. BFRs were detected in 54.84% of samples with a median concentration of 0.01 nmol/mL (range: 0.004-0.051 nmol/mL), while metal elements were detected in more than 90% of samples. No association was found between BFRs and global DNA methylation, unlike metal element levels that showed significant variations with global DNA methylation biomarkers, namely 5-mdC, 5-OH-mdC and N⁶-mA levels. To conclude, Moroccan children could be significantly exposed to flame retardant compounds and heavy metal elements through several routes, such as dust or equipment usage and are therefore susceptible to the adverse health effects that could be linked with such chemicals. Further research is required to assess the exposure to environmental pollutants among the Moroccan population in order to protect Moroccan health and prevent the incidence of diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomonitoring" title="biomonitoring">biomonitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=children" title=" children"> children</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20methylation" title=" DNA methylation"> DNA methylation</a>, <a href="https://publications.waset.org/abstracts/search?q=epigenetics" title=" epigenetics"> epigenetics</a>, <a href="https://publications.waset.org/abstracts/search?q=flame%20retardants" title=" flame retardants"> flame retardants</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=Morocco" title=" Morocco"> Morocco</a> </p> <a href="https://publications.waset.org/abstracts/165618/exposure-assessment-to-heavy-metals-and-flame-retardants-among-moroccan-children-and-their-impact-on-the-epigenetic-profile" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165618.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">97</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Advancement in Scour Protection with Flexible Solutions: Interpretation of Hydraulic Tests Data for Reno Mattresses in Open Channel Flow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paolo%20Di%20Pietro">Paolo Di Pietro</a>, <a href="https://publications.waset.org/abstracts/search?q=Matteo%20Lelli"> Matteo Lelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Kinjal%20Parmar"> Kinjal Parmar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water hazards are consistently identified as among the highest global risks in terms of impact. Riverbank protection plays a key role in flood risk management. For erosion control and scour protection, flexible solutions like gabions & mattresses are being used since quite some time now. The efficacy of erosion control systems depends both on the ability to prevent soil loss underneath, as well as to maintain their integrity under the effects of the water flow. The paper presents the results of a research carried out at the Colorado State University on the performance of double twisted wire mesh products, known as Reno Mattresses, used as soil erosion control system. Mattresses were subjected to various flow conditions on a 10m long flume where they were placed on a 0.30 m thick soil layer. The performance against erosion was evaluated by assessing the effect of the stone motion inside the mattress combined with the condition of incipient soil erosion underneath, in relationship to the mattress thickness, the filling stone properties and under variable hydraulic flow regimes. While confirming the stability obtained using a conventional design approach (commonly referred to tractive force theories), the results of the research allowed to introduce a new performance limit based on incipient soil erosion underneath the revetment. Based on the research results, the authors propose to express the shear resistance of mattresses used as soil erosion control system as a function of the size of the filling stones, their uniformity, their unit weight, the thickness of the mattress, and the presence of vertical connecting elements between the mattress lid and bottom. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reno%20Mattress" title="Reno Mattress">Reno Mattress</a>, <a href="https://publications.waset.org/abstracts/search?q=riverbank%20protection" title=" riverbank protection"> riverbank protection</a>, <a href="https://publications.waset.org/abstracts/search?q=hydraulics" title=" hydraulics"> hydraulics</a>, <a href="https://publications.waset.org/abstracts/search?q=full%20scale%20tests" title=" full scale tests"> full scale tests</a> </p> <a href="https://publications.waset.org/abstracts/181062/advancement-in-scour-protection-with-flexible-solutions-interpretation-of-hydraulic-tests-data-for-reno-mattresses-in-open-channel-flow" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181062.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">24</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Scenario Analysis to Assess the Competitiveness of Hydrogen in Securing the Italian Energy System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gianvito%20Colucci">Gianvito Colucci</a>, <a href="https://publications.waset.org/abstracts/search?q=Valeria%20Di%20Cosmo"> Valeria Di Cosmo</a>, <a href="https://publications.waset.org/abstracts/search?q=Matteo%20Nicoli"> Matteo Nicoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Orsola%20Maria%20Robasto"> Orsola Maria Robasto</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Savoldi"> Laura Savoldi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The hydrogen value chain deployment is likely to be boosted in the near term by the energy security measures planned by European countries to face the recent energy crisis. In this context, some countries are recognized to have a crucial role in the geopolitics of hydrogen as importers, consumers and exporters. According to the European Hydrogen Backbone Initiative, Italy would be part of one of the 5 corridors that will shape the European hydrogen market. However, the set targets are very ambitious and require large investments to rapidly develop effective hydrogen policies: in this regard, scenario analysis is becoming increasingly important to support energy planning, and energy system optimization models appear to be suitable tools to quantitively carry on that kind of analysis. The work aims to assess the competitiveness of hydrogen in contributing to the Italian energy security in the coming years, under different price and import conditions, using the energy system model TEMOA-Italy. A wide spectrum of hydrogen technologies is included in the analysis, covering the production, storage, delivery, and end-uses stages. National production from fossil fuels with and without CCS, as well as electrolysis and import of low-carbon hydrogen from North Africa, are the supply solutions that would compete with other ones, such as natural gas, biomethane and electricity value chains, to satisfy sectoral energy needs (transport, industry, buildings, agriculture). Scenario analysis is then used to study the competition under different price and import conditions. The use of TEMOA-Italy allows the work to catch the interaction between the economy and technological detail, which is much needed in the energy policies assessment, while the transparency of the analysis and of the results is ensured by the full accessibility of the TEMOA open-source modeling framework. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20security" title="energy security">energy security</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20system%20optimization%20models" title=" energy system optimization models"> energy system optimization models</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen" title=" hydrogen"> hydrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20gas" title=" natural gas"> natural gas</a>, <a href="https://publications.waset.org/abstracts/search?q=open-source%20modeling" title=" open-source modeling"> open-source modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=scenario%20analysis" title=" scenario analysis"> scenario analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=TEMOA" title=" TEMOA"> TEMOA</a> </p> <a href="https://publications.waset.org/abstracts/153417/scenario-analysis-to-assess-the-competitiveness-of-hydrogen-in-securing-the-italian-energy-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153417.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">116</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Everyday Interactions among Imprisoned Sex Offenders: A Qualitative Study within the 'Due Palazzi' Prison in Padua</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Matteo%20Mazzucato">Matteo Mazzucato</a>, <a href="https://publications.waset.org/abstracts/search?q=Elena%20Faccio"> Elena Faccio</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Iudici"> Antonio Iudici</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Prison is a social reality constructed by everyday interactions between an inmate, other social actors (cellmates, prison officers, educationalists and psychologists or other detainees) and the external world which participates in this complex construction through the social discourses on prison reality and its problems. Being a detainee means performing a self dealing with processes of stereotypization, attribution of a social role and prejudices assigned by various interlocutors and depending on what kind of crime one has been convicted of. Among all inmates, sex offenders are the ones who risk more to be socially condemned beyond a legal sentence since they have committed one of the most hated and disapproved crime. Regarding this, prison has to be considered as a critical context in which all community expectations and beliefs are converged: for common sense, rapists and child molesters are dangerous people who have to be stigmatized, punished and isolated. Furthermore, other detainees share a code of conduct by which the ‘sex offender’ is collocated at the lowest level of the social hierarchy of the prison. The penitentiary administration too defines this kind of detainee as a ‘vulnerable person to protect’ while prison staff considers him as a particular inmate who has to be treated and definitely changed. Considering all the complexities connected with being imprisoned as a sex offender, our research aimed at exploring how people convicted of sex crimes are called upon to manage all these hetero-narrations about their selves. Set this goal, textual data retrieved from this qualitative research show that sex offenders tend to not face the stigma assigned to them. They are rather used to minimize the story telling about their selves and costruct alternative biographies to be shared with other inmates. Managing narrations about their selves in this way permits to distance them from all the threats perceived living together with other detainees but it blocks sex offenders’ ri-signification of their offences during prison treatment. Given these results, prison administration should develop activities in order to create fields of interaction between detainees where experiencing new versions of their selves spendable even in external social situations. Regarding this it’s important to re-consider prison as part of the community and the sex offenders as a member of it. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interactions" title="interactions">interactions</a>, <a href="https://publications.waset.org/abstracts/search?q=qualitative%20research" title=" qualitative research"> qualitative research</a>, <a href="https://publications.waset.org/abstracts/search?q=prison%20reality" title=" prison reality"> prison reality</a>, <a href="https://publications.waset.org/abstracts/search?q=sex%20offender" title=" sex offender"> sex offender</a> </p> <a href="https://publications.waset.org/abstracts/58457/everyday-interactions-among-imprisoned-sex-offenders-a-qualitative-study-within-the-due-palazzi-prison-in-padua" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58457.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">220</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> West Nile Virus in North-Eastern Italy: Overview of Integrated Surveillance Activities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laura%20Amato">Laura Amato</a>, <a href="https://publications.waset.org/abstracts/search?q=Paolo%20Mulatti"> Paolo Mulatti</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabrizio%20Montarsi"> Fabrizio Montarsi</a>, <a href="https://publications.waset.org/abstracts/search?q=Matteo%20Mazzucato"> Matteo Mazzucato</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Gagliazzo"> Laura Gagliazzo</a>, <a href="https://publications.waset.org/abstracts/search?q=Michele%20Brichese"> Michele Brichese</a>, <a href="https://publications.waset.org/abstracts/search?q=Manlio%20Palei"> Manlio Palei</a>, <a href="https://publications.waset.org/abstracts/search?q=Gioia%20Capelli"> Gioia Capelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Lebana%20Bonfanti"> Lebana Bonfanti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> West Nile virus (WNV) re-emerged in north-eastern Italy in 2008, after ten years from its first appearance in Tuscany. In 2009, a national surveillance programme was implemented, and re-modulated in north-eastern Italy in 2011. Hereby, we present the results of surveillance activities in 2008-2016 in the north-eastern Italian regions, with inferences on WNV epidemiological trend in the area. The re-modulated surveillance programmes aimed at early detecting WNV seasonal reactivation by searching IgM antibodies in horses. In 2013, the surveillance plans were further modified including a risk-based approach. Spatial analysis techniques, including Bernoulli space-time scan-statistics, were applied to the results of 2010–2012 surveillance on mosquitoes, equines, and humans to identify areas where WNV reactivation was more likely to occur. From 2008 to 2016, residential horses tested positive for anti-WNV antibodies on a yearly basis (503 cases), also in areas where WNV circulation was not detected in mosquito populations. Surveillance activities detected 26 syndromic cases in horses, 102 infected mosquito pools and WNV in 18 dead wild birds. Human cases were also recurrently detected in the study area during the surveillance period (68 cases of West Nile neuroinvasive disease). The recurrent identification of WNV in animals, mosquitoes, and humans indicates the virus has likely become endemic in the area. In 2016, findings of WNV positives in horses or mosquitoes were included as triggers for enhancing screening activities in humans. The evolution of the epidemiological situation prompts for continuous and accurate surveillance measures. The results of the 2013-2016 surveillance indicate that the risk-based approach was effective in early detecting seasonal reactivation of WNV, key factor of the integrated surveillance strategy in endemic areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arboviruses" title="arboviruses">arboviruses</a>, <a href="https://publications.waset.org/abstracts/search?q=horses" title=" horses"> horses</a>, <a href="https://publications.waset.org/abstracts/search?q=Italy" title=" Italy"> Italy</a>, <a href="https://publications.waset.org/abstracts/search?q=surveillance" title=" surveillance"> surveillance</a>, <a href="https://publications.waset.org/abstracts/search?q=west%20nile%20virus" title=" west nile virus"> west nile virus</a>, <a href="https://publications.waset.org/abstracts/search?q=zoonoses" title=" zoonoses"> zoonoses</a> </p> <a href="https://publications.waset.org/abstracts/80742/west-nile-virus-in-north-eastern-italy-overview-of-integrated-surveillance-activities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80742.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">358</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Tribological Behavior Of 17-4PH Steel Produced Via Binder Jetting And Low Energy High Current Pulsed Electron Beam Surface Treated</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lorenza%20Fabiocchi">Lorenza Fabiocchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Mariani"> Marco Mariani</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Lucchini%20Huspek"> Andrea Lucchini Huspek</a>, <a href="https://publications.waset.org/abstracts/search?q=Matteo%20Pozzi"> Matteo Pozzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Massimiliano%20Bestetti"> Massimiliano Bestetti</a>, <a href="https://publications.waset.org/abstracts/search?q=Serena%20Graziosi"> Serena Graziosi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nora%20Lecis"> Nora Lecis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Additive manufacturing of stainless steels is rapidly developing thanks to the ability to achieve complex designs effortlessly. Stainless steel 17-4PH is valued for its high strength and corrosion resistance, however intricate geometries are challenging to obtain due to rapid tool wear when machined. Binder jetting additive manufacturing was used to produce 17–4PH samples and pulsed electron beam surface treatment was investigated to enhance surface properties of components. The aim is to improve the tribological performance compared to the as-sintered condition and the H900 aging process, which optimizes hardness and wear resistance. Printed samples were sintered in a reducing atmosphere and superficially treated with an electron beam by varying the voltage (20 - 25 - 30 kV) and pulse count (20 – 40 pulses). Then, the surface was characterized from a microstructural and mechanical standpoint. Scratch tests were performed, and a reciprocating linear pin-on-disk wear test was conducted at 2 N and 10 Hz. Results showed that the voltage affects the roughness and thickness of the treated layer, whilst the number of pulses influences the hardening of the microstructure and consequently the wear resistance. Treated samples exhibited lower coefficients of friction compared to as-printed surfaces, though the values approached those of aged samples after the abrasion of the melted layer, indicating a deeper heat-affected zone formation. Different amounts of residual stress in the heat effected zone were individuated through the scratch tests. Still, the friction remained lower than that of as-printed specimens. This study demonstrates that optimizing electron beam parameters is vital for achieving surface performance comparable to bulk aging treatments, with significant implications for long-term wear resistance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low%20energy%20high%20current%20pulsed%20electron%20beam" title="low energy high current pulsed electron beam">low energy high current pulsed electron beam</a>, <a href="https://publications.waset.org/abstracts/search?q=tribology" title=" tribology"> tribology</a>, <a href="https://publications.waset.org/abstracts/search?q=binder%20jetting%203D%20printing" title=" binder jetting 3D printing"> binder jetting 3D printing</a>, <a href="https://publications.waset.org/abstracts/search?q=17-4PH%20stainless%20steel" title=" 17-4PH stainless steel"> 17-4PH stainless steel</a> </p> <a href="https://publications.waset.org/abstracts/193494/tribological-behavior-of-17-4ph-steel-produced-via-binder-jetting-and-low-energy-high-current-pulsed-electron-beam-surface-treated" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193494.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">9</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Comparison of Hydrogen and Electrification Perspectives in Decarbonizing the Transport Sector</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Matteo%20Nicoli">Matteo Nicoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Gianvito%20Colucci"> Gianvito Colucci</a>, <a href="https://publications.waset.org/abstracts/search?q=Valeria%20Di%20Cosmo"> Valeria Di Cosmo</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniele%20Lerede"> Daniele Lerede</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Savoldi"> Laura Savoldi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The transport sector is currently responsible for approximately 1/3 of greenhouse gas emissions in Europe.

On the other hand, hydrogen-based fuel cell vehicles are available for road and non-road vehicles. The European Commission is strongly pushing toward the integration of hydrogen in the energy systems of European countries and its widespread adoption as an energy vector to achieve the Green Deal targets. Furthermore, the Italian government is defining hydrogen-related objectives with the publication of a dedicated Hydrogen Strategy. The adoption of energy system optimization models to study the possible penetration of alternative zero-emitting transport technologies gives the opportunity to perform an overall analysis of the effects that the development of innovative technologies has on the entire energy system and on the supply-side, devoted to the production of energy carriers such as hydrogen and electricity. Using an open-source modeling framework such as TEMOA, this work aims to compare the role of hydrogen and electric vehicles in the decarbonization of the transport sector. The analysis investigates the advantages and disadvantages of adopting the two options, from the economic point of view (costs associated with the two options) and the environmental one (looking at the emissions reduction perspectives). Moreover, an analysis on the profitability of the investments in hydrogen and electric vehicles will be performed. The study investigates the evolution of energy consumption and greenhouse gas emissions in different transportation modes (road, rail, navigation, and aviation) by detailed analysis of the full range of vehicles included in the techno-economic database used in the TEMOA model instance adopted for this work. The transparency of the analysis is guaranteed by the accessibility of the TEMOA models, based on an open-access source code and databases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=battery%20electric%20vehicles" title="battery electric vehicles">battery electric vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=decarbonization" title=" decarbonization"> decarbonization</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20system%20optimization%20models" title=" energy system optimization models"> energy system optimization models</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20cell%20vehicles" title=" fuel cell vehicles"> fuel cell vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen" title=" hydrogen"> hydrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=open-source%20modeling" title=" open-source modeling"> open-source modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=TEMOA" title=" TEMOA"> TEMOA</a>, <a href="https://publications.waset.org/abstracts/search?q=transport" title=" transport"> transport</a> </p> <a href="https://publications.waset.org/abstracts/153403/comparison-of-hydrogen-and-electrification-perspectives-in-decarbonizing-the-transport-sector" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153403.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">111</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Crowdsensing Project in the Brazilian Municipality of Florianópolis for the Number of Visitors Measurement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Roberto%20De%20Rolt">Carlos Roberto De Rolt</a>, <a href="https://publications.waset.org/abstracts/search?q=Julio%20da%20Silva%20Dias"> Julio da Silva Dias</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafael%20Tezza"> Rafael Tezza</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Foschini"> Luca Foschini</a>, <a href="https://publications.waset.org/abstracts/search?q=Matteo%20Mura"> Matteo Mura</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The seasonal population fluctuation presents a challenge to touristic cities since the number of inhabitants can double according to the season. The aim of this work is to develop a model that correlates the waste collected with the population of the city and also allow cooperation between the inhabitants and the local government. The model allows public managers to evaluate the impact of the seasonal population fluctuation on waste generation and also to improve planning resource utilization throughout the year. The study uses data from the company that collects the garbage in Florianópolis, a Brazilian city that presents the profile of a city that attracts tourists due to numerous beaches and warm weather. The fluctuations are caused by the number of people that come to the city throughout the year for holidays, summer time vacations or business events. Crowdsensing will be accomplished through smartphones with access to an app for data collection, with voluntary participation of the population. Crowdsensing participants can access information collected in waves for this portal. Crowdsensing represents an innovative and participatory approach which involves the population in gathering information to improve the quality of life. The management of crowdsensing solutions plays an essential role given the complexity to foster collaboration, establish available sensors and collect and process the collected data. Practical implications of this tool described in this paper refer, for example, to the management of seasonal tourism in a large municipality, whose public services are impacted by the floating of the population. Crowdsensing and big data support managers in predicting the arrival, permanence, and movement of people in a given urban area. Also, by linking crowdsourced data to databases from other public service providers - e.g., water, garbage collection, electricity, public transport, telecommunications - it is possible to estimate the floating of the population of an urban area affected by seasonal tourism. This approach supports the municipality in increasing the effectiveness of resource allocation while, at the same time, increasing the quality of the service as perceived by citizens and tourists. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=big%20data" title="big data">big data</a>, <a href="https://publications.waset.org/abstracts/search?q=dashboards" title=" dashboards"> dashboards</a>, <a href="https://publications.waset.org/abstracts/search?q=floating%20population" title=" floating population"> floating population</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20city" title=" smart city"> smart city</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20management%20solutions" title=" urban management solutions"> urban management solutions</a> </p> <a href="https://publications.waset.org/abstracts/69059/crowdsensing-project-in-the-brazilian-municipality-of-florianopolis-for-the-number-of-visitors-measurement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69059.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">287</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Assessing the Feasibility of Italian Hydrogen Targets with the Open-Source Energy System Optimization Model TEMOA - Italy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alessandro%20Balbo">Alessandro Balbo</a>, <a href="https://publications.waset.org/abstracts/search?q=Gianvito%20Colucci"> Gianvito Colucci</a>, <a href="https://publications.waset.org/abstracts/search?q=Matteo%20Nicoli"> Matteo Nicoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Savoldi"> Laura Savoldi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hydrogen is expected to become a game changer in the energy transition, especially enabling sector coupling possibilities and the decarbonization of hard-to-abate end-uses. The Italian National Recovery and Resilience Plan identifies hydrogen as one of the key elements of the ecologic transition to meet international decarbonization objectives, also including it in several pilot projects for the early development in Italy. This matches the European energy strategy, which aims to make hydrogen a leading energy carrier of the future, setting ambitious goals to be accomplished by 2030. The huge efforts needed to achieve the announced targets require to carefully investigate of their feasibility in terms of economic expenditures and technical aspects. In order to quantitatively assess the hydrogen potential within the Italian context and the feasibility of the planned investments and projects, this work uses the TEMOA-Italy energy system model to study pathways to meet the strict objectives above cited. The possible hydrogen development has been studied both in the supply-side and demand-side of the energy system, also including storage options and distribution chains. The assessment comprehends alternative hydrogen production technologies involved in a competition market, reflecting the several possible investments declined by the Italian National Recovery and Resilience Plan to boost the development and spread of this infrastructure, including the sector coupling potential with natural gas through the currently existing infrastructure and CO2 capture for the production of synfuels. On the other hand, the hydrogen end-uses phase covers a wide range of consumption alternatives, from fuel-cell vehicles, for which both road and non-road transport categories are considered, to steel, and chemical industries uses and cogeneration for residential and commercial buildings. The model includes both high and low TRL technologies in order to provide a consistent outcome for the future decades as it does for the present day, and since it is developed through the use of an open-source code instance and database, transparency and accessibility are fully granted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decarbonization" title="decarbonization">decarbonization</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20system%20optimization%20models" title=" energy system optimization models"> energy system optimization models</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen" title=" hydrogen"> hydrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=open-source%20modeling" title=" open-source modeling"> open-source modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=TEMOA" title=" TEMOA"> TEMOA</a> </p> <a href="https://publications.waset.org/abstracts/153400/assessing-the-feasibility-of-italian-hydrogen-targets-with-the-open-source-energy-system-optimization-model-temoa-italy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153400.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">101</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Spatial Climate Changes in the Province of Macerata, Central Italy, Analyzed by GIS Software </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Matteo%20Gentilucci">Matteo Gentilucci</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Materazzi"> Marco Materazzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Gilberto%20Pambianchi"> Gilberto Pambianchi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Climate change is an increasingly central issue in the world, because it affects many of human activities. In this context regional studies are of great importance because they sometimes differ from the general trend. This research focuses on a small area of central Italy which overlooks the Adriatic Sea, the province of Macerata. The aim is to analyze space-based climate changes, for precipitation and temperatures, in the last 3 climatological standard normals (1961-1990; 1971-2000; 1981-2010) through GIS software. The data collected from 30 weather stations for temperature and 61 rain gauges for precipitation were subject to quality controls: validation and homogenization. These data were fundamental for the spatialization of the variables (temperature and precipitation) through geostatistical techniques. To assess the best geostatistical technique for interpolation, the results of cross correlation were used. The co-kriging method with altitude as independent variable produced the best cross validation results for all time periods, among the methods analysed, with 'root mean square error standardized' close to 1, 'mean standardized error' close to 0, 'average standard error' and 'root mean square error' with similar values. The maps resulting from the analysis were compared by subtraction between rasters, producing 3 maps of annual variation and three other maps for each month of the year (1961/1990-1971/2000; 1971/2000-1981/2010; 1961/1990-1981/2010). The results show an increase in average annual temperature of about 0.1°C between 1961-1990 and 1971-2000 and 0.6 °C between 1961-1990 and 1981-2010. Instead annual precipitation shows an opposite trend, with an average difference from 1961-1990 to 1971-2000 of about 35 mm and from 1961-1990 to 1981-2010 of about 60 mm. Furthermore, the differences in the areas have been highlighted with area graphs and summarized in several tables as descriptive analysis. In fact for temperature between 1961-1990 and 1971-2000 the most areally represented frequency is 0.08°C (77.04 Km² on a total of about 2800 km²) with a kurtosis of 3.95 and a skewness of 2.19. Instead, the differences for temperatures from 1961-1990 to 1981-2010 show a most areally represented frequency of 0.83 °C, with -0.45 as kurtosis and 0.92 as skewness (36.9 km²). Therefore it can be said that distribution is more pointed for 1961/1990-1971/2000 and smoother but more intense in the growth for 1961/1990-1981/2010. In contrast, precipitation shows a very similar shape of distribution, although with different intensities, for both variations periods (first period 1961/1990-1971/2000 and second one 1961/1990-1981/2010) with similar values of kurtosis (1st = 1.93; 2nd = 1.34), skewness (1st = 1.81; 2nd = 1.62 for the second) and area of the most represented frequency (1st = 60.72 km²; 2nd = 52.80 km²). In conclusion, this methodology of analysis allows the assessment of small scale climate change for each month of the year and could be further investigated in relation to regional atmospheric dynamics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=GIS" title=" GIS"> GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=interpolation" title=" interpolation"> interpolation</a>, <a href="https://publications.waset.org/abstracts/search?q=co-kriging" title=" co-kriging"> co-kriging</a> </p> <a href="https://publications.waset.org/abstracts/96305/spatial-climate-changes-in-the-province-of-macerata-central-italy-analyzed-by-gis-software" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96305.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">127</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Exploring the Role of Hydrogen to Achieve the Italian Decarbonization Targets using an OpenScience Energy System Optimization Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alessandro%20Balbo">Alessandro Balbo</a>, <a href="https://publications.waset.org/abstracts/search?q=Gianvito%20Colucci"> Gianvito Colucci</a>, <a href="https://publications.waset.org/abstracts/search?q=Matteo%20Nicoli"> Matteo Nicoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Savoldi"> Laura Savoldi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hydrogen is expected to become an undisputed player in the ecological transition throughout the next decades. The decarbonization potential offered by this energy vector provides various opportunities for the so-called “hard-to-abate” sectors, including industrial production of iron and steel, glass, refineries and the heavy-duty transport. In this regard, Italy, in the framework of decarbonization plans for the whole European Union, has been considering a wider use of hydrogen to provide an alternative to fossil fuels in hard-to-abate sectors. This work aims to assess and compare different options concerning the pathway to be followed in the development of the future Italian energy system in order to meet decarbonization targets as established by the Paris Agreement and by the European Green Deal, and to infer a techno-economic analysis of the required asset alternatives to be used in that perspective. To accomplish this objective, the Energy System Optimization Model TEMOA-Italy is used, based on the open-source platform TEMOA and developed at PoliTo as a tool to be used for technology assessment and energy scenario analysis. The adopted assessment strategy includes two different scenarios to be compared with a business-as-usual one, which considers the application of current policies in a time horizon up to 2050. The studied scenarios are based on the up-to-date hydrogen-related targets and planned investments included in the National Hydrogen Strategy and in the Italian National Recovery and Resilience Plan, with the purpose of providing a critical assessment of what they propose. One scenario imposes decarbonization objectives for the years 2030, 2040 and 2050, without any other specific target. The second one (inspired to the national objectives on the development of the sector) promotes the deployment of the hydrogen value-chain. These scenarios provide feedback about the applications hydrogen could have in the Italian energy system, including transport, industry and synfuels production. Furthermore, the decarbonization scenario where hydrogen production is not imposed, will make use of this energy vector as well, showing the necessity of its exploitation in order to meet pledged targets by 2050. The distance of the planned policies from the optimal conditions for the achievement of Italian objectives is be clarified, revealing possible improvements of various steps of the decarbonization pathway, which seems to have as a fundamental element Carbon Capture and Utilization technologies for its accomplishment. In line with the European Commission open science guidelines, the transparency and the robustness of the presented results is ensured by the adoption of the open-source open-data model such as the TEMOA-Italy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decarbonization" title="decarbonization">decarbonization</a>, <a
