We derive such sparse solutions by adding a genuine sparsity requirement to the original Principal Components Analysis (PCA) objective function. This approach differs from others because it preserves PCA's original optimality: uncorrelatedness of the components and least squares approximation of the data. To identify the best subset of non-zero loadings we propose a branch-and-bound search and an iterative elimination algorithm. This last algorithm finds sparse solutions with large loadings and can be run without specifying the cardinality of the loadings and the number of components to compute in advance. We give thorough comparisons with the existing sparse PCA methods and several examples on real datasets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SPCA" title="SPCA">SPCA</a>, <a href="https://publications.waset.org/abstracts/search?q=uncorrelated%20components" title=" uncorrelated components"> uncorrelated components</a>, <a href="https://publications.waset.org/abstracts/search?q=branch-and-bound" title=" branch-and-bound"> branch-and-bound</a>, <a href="https://publications.waset.org/abstracts/search?q=backward%20elimination" title=" backward elimination"> backward elimination</a> </p> <a href="https://publications.waset.org/abstracts/14630/sparse-principal-component-analysis-a-least-squares-approximation-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14630.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">381</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">45</span> Contemporary Anti-Gypsyism in European Mass Media</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elisabetta%20Di%20Giovanni">Elisabetta Di Giovanni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper focuses on the contemporary phenomenon of Anti-Gypsyism which is widely diffused on social representations of the so called 'Gypsies'.

Because of the difficulties in the experimental investigation of the mutual interaction between flow alteration and early flame kernel convection effect inside the engine combustion chamber, CFD-3D simulation is usually exploited in such cases. Experimentally speaking, a particular type of engine has to be used in order to directly observe the flame propagation process. In this study, a double electrode spark plug was fitted into an optically accessible engine and a high-speed camera was used to capture the initial stages of the combustion process. Both the arc and the kernel phases were observed. Then, a morphologic analysis was carried out and the position of the center of mass of the flame, relative to the spark plug position, was calculated. The crossflow orientation was chosen for the spark plug and the kernel growth process was observed for different air-fuel ratios. It was observed that during a normal cycle the flow field between the electrodes tends to transport the arc deforming it. Because of that, the kernel growth phase takes place away from the electrodes and the flame propagates with a preferential direction dictated by the flow field. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Combustion" title="Combustion">Combustion</a>, <a href="https://publications.waset.org/abstracts/search?q=Optically%20Accessible%20Engine" title=" Optically Accessible Engine"> Optically Accessible Engine</a>, <a href="https://publications.waset.org/abstracts/search?q=Spark-Ignition%20Engine" title=" Spark-Ignition Engine"> Spark-Ignition Engine</a>, <a href="https://publications.waset.org/abstracts/search?q=Sparl%20Orientation" title=" Sparl Orientation"> Sparl Orientation</a>, <a href="https://publications.waset.org/abstracts/search?q=Kernel%20Growth" title=" Kernel Growth"> Kernel Growth</a> </p> <a href="https://publications.waset.org/abstracts/122902/flame-kernel-growth-and-related-effects-of-spark-plug-electrodes-fluid-motion-interaction-in-an-optically-accessible-disi-engine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122902.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">142</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">43</span> Lumped Parameter Models for Numerical Simulation of The Dynamic Response of Hoisting Appliances</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Candida%20Petrogalli">Candida Petrogalli</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Incerti"> Giovanni Incerti</a>, <a href="https://publications.waset.org/abstracts/search?q=Luigi%20Solazzi"> Luigi Solazzi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes three lumped parameters models for the study of the dynamic behaviour of a boom crane.

Besides considering the belt elasticity, the mathematical model here proposed also takes into consideration the electrical behaviour of the DC motor. The solution of the motion equations is obtained by means of the modal analysis in state space, which allows to obtain the decoupling of all equations of the mathematical model without introducing the hypothesis of proportional damping. The mathematical model of the transmission and the solution algorithms have been implemented within a computing software that allows the user to simulate the dynamics of the system and to evaluate the effects due to the elasticity of the belt branches and to the electromagnetic behavior of the DC motor.

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 effectiveness of the methodology is demonstrated by testing an independent sample of additional woodworking machines without presenting machine down event. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=predictive%20maintenance" title="predictive maintenance">predictive maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=connected%20machines" title=" connected machines"> connected machines</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a> </p> <a href="https://publications.waset.org/abstracts/98461/predicting-machine-down-of-woodworking-industrial-machines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98461.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">226</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">36</span> Sport Facilities and Social Change: European Funds as an Opportunity for Urban Regeneration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lorenzo%20Maiorino">Lorenzo Maiorino</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabio%20Fortuna"> Fabio Fortuna</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Panebianco"> Giovanni Panebianco</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Sanzari"> Marco Sanzari</a>, <a href="https://publications.waset.org/abstracts/search?q=Gabriella%20Arcese"> Gabriella Arcese</a>, <a href="https://publications.waset.org/abstracts/search?q=Valerio%20Maria%20Paolozzi"> Valerio Maria Paolozzi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is well known that sport is a factor of social cohesion and the breaking down of barriers between people. From this point of view, the aim is to demonstrate how, through the (re)generation of sustainable structures, it is possible to give life to a new social, cultural, and economic pathway, where possible, in peripheral areas with problems of abandonment and degradation. The aim of this paper is, therefore, to study realities such as European programs and funds and to highlight the ways in which planning can be used to respond to critical issues such as urban decay, abandonment, and the mitigation of social differences. For this reason, the analysis will be carried out through the Multiannual Financial Framework (MFF) package, the Next Generation EU, the Recovery and Resilience Facility (RRF), the Cohesion Fund, the European Social Fund, and other managed funds. The procedure will rely on sources and data of unquestionable origin, and the relation to the object of study in question will be highlighted. The project lends itself to be ambitious and exploring a further aspect of the sports theme, which, as we know, is one of the foundations for a healthy society. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sport" title="sport">sport</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20inclusion" title=" social inclusion"> social inclusion</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20regeneration" title=" urban regeneration"> urban regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=sports%20facilities" title=" sports facilities"> sports facilities</a>, <a href="https://publications.waset.org/abstracts/search?q=European%20funds" title=" European funds"> European funds</a> </p> <a href="https://publications.waset.org/abstracts/142426/sport-facilities-and-social-change-european-funds-as-an-opportunity-for-urban-regeneration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142426.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">225</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">35</span> Site Effect Observations after 2016 Amatrice Earthquake, Central Italy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Forte">Giovanni Forte</a>, <a href="https://publications.waset.org/abstracts/search?q=Melania%20De%20Falco"> Melania De Falco</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Santo"> Antonio Santo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> On 24th August 2016, central Italy was affected by a Mw 6.0 earthquake, representing the main shock of a long seismic sequence, which had a second shock Mw 6.6 on 26th October and lasts still nowadays. After the event, several field survey were carried out in the affected areas, which is made of historical masonry buildings. The post event reconnaissance missions were aimed at collecting information on the damage states of the buildings, the triggering of the landslides and the relationships with site effects. In this paper, the data collected after the event are analyzed considering the role of the geological and geomorphological setting and the ground motion scenario. The buildings displayed an uneven damage distribution, which was affected by both topographic and stratigraphic amplification. As pertains the landslides, which were the most recurrent among the ground failures, consisted mainly of rock falls and subordinately of translational slides. Finally, the collected knowledge showed a strong contribution of the local geological and geomorphological site condition on the resulting damage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amatrice%20earthquake" title="Amatrice earthquake">Amatrice earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=damage%20states" title=" damage states"> damage states</a>, <a href="https://publications.waset.org/abstracts/search?q=landslides" title=" landslides"> landslides</a>, <a href="https://publications.waset.org/abstracts/search?q=site%20effects" title=" site effects"> site effects</a> </p> <a href="https://publications.waset.org/abstracts/69468/site-effect-observations-after-2016-amatrice-earthquake-central-italy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69468.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">323</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">34</span> Analysis of the Diffusion Behavior of an Information and Communication Technology Platform for City Logistics </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Giulio%20Mangano">Giulio Mangano</a>, <a href="https://publications.waset.org/abstracts/search?q=Alberto%20De%20Marco"> Alberto De Marco</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Zenezini"> Giovanni Zenezini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The concept of City Logistics (CL) has emerged to improve the impacts of last mile freight distribution in urban areas. In this paper, a System Dynamics (SD) model exploring the dynamics of the diffusion of a ICT platform for CL management across different populations is proposed. For the development of the model two sources have been used. On the one hand, the major diffusion variables and feedback loops are derived from a literature review of existing diffusion models. On the other hand, the parameters are represented by the value propositions delivered by the platform as a response to some of the users’ needs. To extract the most important value propositions the Business Model Canvas approach has been used. Such approach in fact focuses on understanding how a company can create value for her target customers. These variables and parameters are thus translated into a SD diffusion model with three different populations namely municipalities, logistics service providers, and own account carriers. Results show that, the three populations under analysis fully adopt the platform within the simulation time frame, highlighting a strong demand by different stakeholders for CL projects aiming at carrying out more efficient urban logistics operations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=city%20logistics" title="city logistics">city logistics</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=system%20dynamics" title=" system dynamics"> system dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20model" title=" business model"> business model</a> </p> <a href="https://publications.waset.org/abstracts/75009/analysis-of-the-diffusion-behavior-of-an-information-and-communication-technology-platform-for-city-logistics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75009.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">266</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">33</span> Clonal Evaluation of Malignant Mesothelioma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabahattin%20Comertpay">Sabahattin Comertpay</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Pastorino"> Sandra Pastorino</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosanna%20Mezzapelle"> Rosanna Mezzapelle</a>, <a href="https://publications.waset.org/abstracts/search?q=Mika%20Tanji"> Mika Tanji</a>, <a href="https://publications.waset.org/abstracts/search?q=Oriana%20Strianese"> Oriana Strianese</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Napolitano"> Andrea Napolitano</a>, <a href="https://publications.waset.org/abstracts/search?q=Tracey%20Weigel"> Tracey Weigel</a>, <a href="https://publications.waset.org/abstracts/search?q=Joseph%20Friedberg"> Joseph Friedberg</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Sugarbaker"> Paul Sugarbaker</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Krausz"> Thomas Krausz</a>, <a href="https://publications.waset.org/abstracts/search?q=Ena%20Wang"> Ena Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Amy%20Powers"> Amy Powers</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Gaudino"> Giovanni Gaudino</a>, <a href="https://publications.waset.org/abstracts/search?q=Harvey%20I.%20Pass"> Harvey I.

This paradigm arose decades ago, primarily from the study of hematopoietic malignancies and sarcomas. The clonal origin of malignant mesothelioma (MM), a deadly cancer resistant to the current therapies, has not been investigated. Examination of the pleura from patients with MM shows often the presence of multiple pleural nodules, raising the question of whether they represent independent or metastatic growth processes. To investigate the clonality patterns of MM, we used the HUMARA (Human Androgen Receptor) assay to examine 14 sporadic and 2 familial Malignant Mesotheliomas (MM). Of 16 specimens studied, 15 were informative and 14/15 revealed two electrophoretically distinct methylated HUMARA alleles, indicating a polyclonal origin for these tumors. This discovery has important clinical implications, because an accurate assessment of tumor clonality is key to the design of novel molecular strategies for the treatment of MM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=malignant%20mesothelioma" title="malignant mesothelioma">malignant mesothelioma</a>, <a href="https://publications.waset.org/abstracts/search?q=clonal%20origin" title=" clonal origin"> clonal origin</a>, <a href="https://publications.waset.org/abstracts/search?q=HUMARA" title=" HUMARA"> HUMARA</a>, <a href="https://publications.waset.org/abstracts/search?q=sarcomas" title=" sarcomas"> sarcomas</a> </p> <a href="https://publications.waset.org/abstracts/14879/clonal-evaluation-of-malignant-mesothelioma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14879.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">458</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> Use of Psychiatric Services and Psychotropics in Children with Atopic Dermatitis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mia%20Schneeweiss">Mia Schneeweiss</a>, <a href="https://publications.waset.org/abstracts/search?q=Joseph%20Merola"> Joseph Merola</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Atopic dermatitis (AD) is a chronic inflammatory skin condition with a prevalence of 9.6 million in children under the age of 18 in the US, 3.2 million of those suffer severe AD. AD has significant effects on the quality of life and psychiatric comorbidity in affected patients. We sought to quantify the use of psychotropic medications and mental health services in children. We used longitudinal claims data form commercially insured patients in the US between 2003 and 2016 to identify children aged 18 or younger with a diagnosis of AD associated with an outpatient or inpatient encounter. A 180-day enrollment period was required before the first diagnosis of AD. Among those diagnosed, we computed the use of psychiatric services and dispensing of psychotropic medications during the following 6 months. Among 1.6 million children <18 years with a diagnosis of AD, most were infants (0-1 years: 17.6%), babies (1-2 years: 12.2%) and young children (2-4 years: 15.4). 5.1% were in age group 16-18 years. Among younger children 50% of patients were female, after the age of 14 about 60% were female. In 16-18 years olds 6.4% had at least one claim with a recorded psychopathology during the 6-month baseline period; 4.6% had depression, 3.3% anxiety, 0.3% panic disorder, 0.6% psychotic disorder, 0.1% anorexia. During the 6 months following the physician diagnosis of AD, 66% used high-potency topical corticosteroids, 3.5% used an SSRI, 0.3% used an SNRI, 1.2% used a tricyclic antidepressant, 1.4% used an antipsychotic medication, and 5.2% used an anxiolytic agent. 4.4% had an outpatient visit with a psychiatrist and 0.1% had been hospitalized with a psychiatric diagnosis. In 14-16 years olds, 4.7% had at least one claim with a recorded psychopathology during the 6-month baseline period; 3.3% had depression, 2.5% anxiety, 0.2% panic disorder, 0.5% psychotic disorder, 0.1% anorexia. During the 6 months following the physician diagnosis of AD, 68% used high-potency topical corticosteroids, 4.6% used an SSRI, 0.6% used an SNRI, 1.5% used a tricyclic antidepressant, 1.4% used an antipsychotic medication, and 4.6% used an anxiolytic agent. 4.7% had an outpatient visit with a psychiatrist and 0.1% had been hospitalized with a psychiatric diagnosis. In 12-14 years olds, 3.3% had at least one claim with a recorded psychopathology during the 6-month baseline period; 1.9% had depression, 2.2% anxiety, 0.1% panic disorder, 0.7% psychotic disorder, 0.0% anorexia. During the 6 months following the physician diagnosis of AD, 67% used high-potency topical corticosteroids, 2.1% used an SSRI, 0.1% used an SNRI, 0.7% used a tricyclic antidepressant, 0.9 % used an antipsychotic medication, and 4.1% used an anxiolytic agent. 3.8% had an outpatient visit with a psychiatrist and 0.05% had been hospitalized with a psychiatric diagnosis. In younger children psychopathologies were decreasingly common: 10-12: 2.8%; 8-10: 2.3%; 6-8: 1.3%; 4-6: 0.6%. In conclusion, there is substantial psychiatric comorbidity among children, <18 years old, with diagnosed atopic dermatitis in a US commercially insured population. Meaningful psychiatric medication use (>3%) starts as early as 12 years old. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pediatric%20atopic%20dermatitis" title="pediatric atopic dermatitis">pediatric atopic dermatitis</a>, <a href="https://publications.waset.org/abstracts/search?q=phychotropic%20medication%20use" title=" phychotropic medication use"> phychotropic medication use</a>, <a href="https://publications.waset.org/abstracts/search?q=psychiatric%20comorbidity" title=" psychiatric comorbidity"> psychiatric comorbidity</a>, <a href="https://publications.waset.org/abstracts/search?q=claims%20database" title=" claims database"> claims database</a> </p> <a href="https://publications.waset.org/abstracts/91005/use-of-psychiatric-services-and-psychotropics-in-children-with-atopic-dermatitis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91005.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">176</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">31</span> The Determinants of Country Corruption: Unobserved Heterogeneity and Individual Choice- An empirical Application with Finite Mixture Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alessandra%20Marcelletti">Alessandra Marcelletti</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Trovato"> Giovanni Trovato</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Corruption in public offices is found to be the reflection of country-specific features, however, the exact magnitude and the statistical significance of its determinants effect has not yet been identified. The paper aims to propose an estimation method to measure the impact of country fundamentals on corruption, showing that covariates could differently affect the extent of corruption across countries. Thus, we exploit a model able to take into account different factors affecting the incentive to ask or to be asked for a bribe, coherently with the use of the Corruption Perception Index. We assume that discordant results achieved in literature may be explained by omitted hidden factors affecting the agents' decision process. Moreover, assuming homogeneous covariates effect may lead to unreliable conclusions since the country-specific environment is not accounted for. We apply a Finite Mixture Model with concomitant variables to 129 countries from 1995 to 2006, accounting for the impact of the initial conditions in the socio-economic structure on the corruption patterns. Our findings confirm the hypothesis of the decision process of accepting or asking for a bribe varies with specific country fundamental features. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Corruption" title="Corruption">Corruption</a>, <a href="https://publications.waset.org/abstracts/search?q=Finite%20Mixture%20Models" title=" Finite Mixture Models"> Finite Mixture Models</a>, <a href="https://publications.waset.org/abstracts/search?q=Concomitant%20Variables" title=" Concomitant Variables"> Concomitant Variables</a>, <a href="https://publications.waset.org/abstracts/search?q=Countries%20Classification" title=" Countries Classification"> Countries Classification</a> </p> <a href="https://publications.waset.org/abstracts/23112/the-determinants-of-country-corruption-unobserved-heterogeneity-and-individual-choice-an-empirical-application-with-finite-mixture-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23112.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">263</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">30</span> The Vocality of Sibyl Sanderson in Massenet’s Manon and Esclarmonde: Musical Training and Critical Response</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tamara%20Thompson">Tamara Thompson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This presentation will address the vocality of American soprano Sibyl Sanderson (1865–1903) in Massenet’s Manon and Esclarmonde as discernible from documentary sources such as vocal treatises, annotated scores, and correspondence. These sources will then be compared and contrasted with Sanderson’s reception in French press. Sanderson sang Manon in 1888, which Massenet revised for her. She then created the role of Esclarmonde for the 1889 l'Exposition Universelle in Paris. The soprano appeared as the Byzantine Empress more than 100 times in the nine months following the premiere, which secured her fame and an international operatic career frought with controversy and criticism as well as adulation. Before her débuts as Manon and Esclarmonde, Sanderson received musical training in California and Paris from multiple teachers with varied and opposing methods. There will be an exploration of the ways in which the disparate pedagogic influences such as those taught by Giovanni Sbriglia and Jean de Reszké may have guided Sanderson’s vocal strategies, and possibly caused or promoted the severe vocal pathologies she battled in subsequent years. In addition, there is interrogation of the vocal writing and revisions made to the titular roles for Sanderson in order to assess how these factors may have affected her technique and vocal health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=French" title="French">French</a>, <a href="https://publications.waset.org/abstracts/search?q=nineteenth-century" title=" nineteenth-century"> nineteenth-century</a>, <a href="https://publications.waset.org/abstracts/search?q=opera" title=" opera"> opera</a>, <a href="https://publications.waset.org/abstracts/search?q=pedagogy" title=" pedagogy"> pedagogy</a>, <a href="https://publications.waset.org/abstracts/search?q=vocality" title=" vocality"> vocality</a> </p> <a href="https://publications.waset.org/abstracts/65824/the-vocality-of-sibyl-sanderson-in-massenets-manon-and-esclarmonde-musical-training-and-critical-response" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65824.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">279</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">29</span> Application of Italian Guidelines for Existing Bridge Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Menichini">Giovanni Menichini</a>, <a href="https://publications.waset.org/abstracts/search?q=Salvatore%20Giacomo%20Morano"> Salvatore Giacomo Morano</a>, <a href="https://publications.waset.org/abstracts/search?q=Gloria%20Terenzi"> Gloria Terenzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Salvatori"> Luca Salvatori</a>, <a href="https://publications.waset.org/abstracts/search?q=Maurizio%20Orlando"> Maurizio Orlando</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The “Guidelines for Risk Classification, Safety Assessment, and Structural Health Monitoring of Existing Bridges” were recently approved by the Italian Government to define technical standards for managing the national network of existing bridges. These guidelines provide a framework for risk mitigation and safety assessment of bridges, which are essential elements of the built environment and form the basis for the operation of transport systems. Within the guideline framework, a workflow based on three main points was proposed: (1) risk-based, i.e., based on typical parameters of hazard, vulnerability, and exposure; (2) multi-level, i.e., including six assessment levels of increasing complexity; and (3) multirisk, i.e., assessing structural/foundational, seismic, hydrological, and landslide risks. The paper focuses on applying the Italian Guidelines to specific case studies, aiming to identify the parameters that predominantly influence the determination of the “class of attention”.

In this aspect, an implemented approach is proposed in the present work to boost a 1.5 L, three-cylinder Diesel engine with a new turbocharger, based on 1D preliminary design codes, 3D design, and numerical assessment of a suitable radial turbine followed by an accurate selection procedure of an adequate centrifugal compressor. Furthermore, to investigate the effect of the turbine’s rotor position on the simulation convergence, stability, and calculation time; two combinations (rotor blade- volute) have been assessed. Consequently, significant results are obtained when comparing the original turbocharged engine and the new one at the engine’s full load and rated speed (@4500rpm) conditions. A maximum improvement in terms of brake-specific fuel consumption, thermal efficiency, total-to-static turbine efficiency, and total-to-total compressor efficiency equal 6.5% (corresponding to a decrease of 2.3 litre/hr in fuel consumption), 7%, 10.9%, and 19.9%, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD%20investigation" title="CFD investigation">CFD investigation</a>, <a href="https://publications.waset.org/abstracts/search?q=engine%20boosting" title=" engine boosting"> engine boosting</a>, <a href="https://publications.waset.org/abstracts/search?q=turbine%20design" title=" turbine design"> turbine design</a>, <a href="https://publications.waset.org/abstracts/search?q=turbocharger" title=" turbocharger"> turbocharger</a>, <a href="https://publications.waset.org/abstracts/search?q=rotor%20blade%20positioning" title=" rotor blade positioning"> rotor blade positioning</a> </p> <a href="https://publications.waset.org/abstracts/158211/numerical-approach-to-boost-an-internal-combustion-engine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158211.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">118</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">27</span> A Machine Learning Approach for Anomaly Detection in Environmental IoT-Driven Wastewater Purification Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Cicceri">Giovanni Cicceri</a>, <a href="https://publications.waset.org/abstracts/search?q=Roberta%20Maisano"> Roberta Maisano</a>, <a href="https://publications.waset.org/abstracts/search?q=Nathalie%20Morey"> Nathalie Morey</a>, <a href="https://publications.waset.org/abstracts/search?q=Salvatore%20Distefano"> Salvatore Distefano</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main goal of this paper is to present a solution for a water purification system based on an Environmental Internet of Things (EIoT) platform to monitor and control water quality and machine learning (ML) models to support decision making and speed up the processes of purification of water. A real case study has been implemented by deploying an EIoT platform and a network of devices, called Gramb meters and belonging to the Gramb project, on wastewater purification systems located in Calabria, south of Italy. The data thus collected are used to control the wastewater quality, detect anomalies and predict the behaviour of the purification system. To this extent, three different statistical and machine learning models have been adopted and thus compared: Autoregressive Integrated Moving Average (ARIMA), Long Short Term Memory (LSTM) autoencoder, and Facebook Prophet (FP). The results demonstrated that the ML solution (LSTM) out-perform classical statistical approaches (ARIMA, FP), in terms of both accuracy, efficiency and effectiveness in monitoring and controlling the wastewater purification processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20internet%20of%20things" title="environmental internet of things">environmental internet of things</a>, <a href="https://publications.waset.org/abstracts/search?q=EIoT" title=" EIoT"> EIoT</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=anomaly%20detection" title=" anomaly detection"> anomaly detection</a>, <a href="https://publications.waset.org/abstracts/search?q=environment%20monitoring" title=" environment monitoring"> environment monitoring</a> </p> <a href="https://publications.waset.org/abstracts/130838/a-machine-learning-approach-for-anomaly-detection-in-environmental-iot-driven-wastewater-purification-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130838.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">151</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">26</span> Metal-Organic Frameworks-Based Materials for Volatile Organic Compounds Sensing Applications: Strategies to Improve Sensing Performances</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Claudio%20Clemente">Claudio Clemente</a>, <a href="https://publications.waset.org/abstracts/search?q=Valentina%20Gargiulo"> Valentina Gargiulo</a>, <a href="https://publications.waset.org/abstracts/search?q=Alessio%20Occhicone"> Alessio Occhicone</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Piero%20Pepe"> Giovanni Piero Pepe</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Ausanio"> Giovanni Ausanio</a>, <a href="https://publications.waset.org/abstracts/search?q=Michela%20Alf%C3%A8"> Michela Alfè</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Volatile organic compound (VOC) emissions represent a serious risk to human health and the integrity of the ecosystems, especially at high concentrations. For this reason, it is very important to continuously monitor environmental quality and develop fast and reliable portable sensors to allow analysis on site. Chemiresistors have become promising candidates for VOC sensing as their ease of fabrication, variety of suitable sensitive materials, and simple sensing data. A chemoresistive gas sensor is a transducer that allows to measure the concentration of an analyte in the gas phase because the changes in resistance are proportional to the amount of the analyte present. The selection of the sensitive material, which interacts with the target analyte, is very important for the sensor performance. The most used VOC detection materials are metal oxides (MOx) for their rapid recovery, high sensitivity to various gas molecules, easy fabrication. Their sensing performance can be improved in terms of operating temperature, selectivity, and detection limit. Metal-organic frameworks (MOFs) have attracted a lot of attention also in the field of gas sensing due to their high porosity, high surface area, tunable morphologies, structural variety. MOFs are generated by the self-assembly of multidentate organic ligands connecting with adjacent multivalent metal nodes via strong coordination interactions, producing stable and highly ordered crystalline porous materials with well-designed structures. However, most MOFs intrinsically exhibit low electrical conductivity. To improve this property, MOFs can be combined with organic and inorganic materials in a hybrid fashion to produce composite materials or can be transformed into more stable structures. MOFs, indeed, can be employed as the precursors of metal oxides with well-designed architectures via the calcination method. The MOF-derived MOx partially preserved the original structure with high surface area and intrinsic open pores, which act as trapping centers for gas molecules, and showed a higher electrical conductivity. Core-shell heterostructures, in which the surface of a metal oxide core is completely coated by a MOF shell, forming a junction at the core-shell heterointerface, can also be synthesized. Also, nanocomposite in which MOF structures are intercalated with graphene related materials can also be produced, and the conductivity increases thanks to the high mobility of electrons of carbon materials. As MOF structures, zinc-based MOFs belonging to the ZIF family were selected in this work. Several Zn-based materials based and/or derived from MOFs were produced, structurally characterized, and arranged in a chemo resistive architecture, also exploring the potentiality of different approaches of sensing layer deposition based on PLD (pulsed laser deposition) and, in case of thermally labile materials, MAPLE (Matrix Assisted Pulsed Laser Evaporation) to enhance the adhesion to the support. The sensors were tested in a controlled humidity chamber, allowing for the possibility of varying the concentration of ethanol, a typical analyte chosen among the VOCs for a first survey. The effect of heating the chemiresistor to improve sensing performances was also explored. Future research will focus on exploring new manufacturing processes for MOF-based gas sensors with the aim to improve sensitivity, selectivity and reduce operating temperatures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemiresistors" title="chemiresistors">chemiresistors</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20sensors" title=" gas sensors"> gas sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene%20related%20materials" title=" graphene related materials"> graphene related materials</a>, <a href="https://publications.waset.org/abstracts/search?q=laser%20deposition" title=" laser deposition"> laser deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=MAPLE" title=" MAPLE"> MAPLE</a>, <a href="https://publications.waset.org/abstracts/search?q=metal-organic%20frameworks" title=" metal-organic frameworks"> metal-organic frameworks</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20oxides" title=" metal oxides"> metal oxides</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposites" title=" nanocomposites"> nanocomposites</a>, <a href="https://publications.waset.org/abstracts/search?q=sensing%20performance" title=" sensing performance"> sensing performance</a>, <a href="https://publications.waset.org/abstracts/search?q=transduction%20mechanism" title=" transduction mechanism"> transduction mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=volatile%20organic%20compounds" title=" volatile organic compounds"> volatile organic compounds</a> </p> <a href="https://publications.waset.org/abstracts/184645/metal-organic-frameworks-based-materials-for-volatile-organic-compounds-sensing-applications-strategies-to-improve-sensing-performances" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184645.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">63</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> Fuel Oxidation Reactions: Pathways and Reactive Intermediates Characterization via Synchrotron Photoionization Mass Spectrometry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Meloni">Giovanni Meloni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recent results are presented from experiments carried out at the Advanced Light Source (ALS) at the Chemical Dynamics Beamline of Lawrence Berkeley National Laboratory using multiplexed synchrotron photoionization mass spectrometry. The reaction mixture and a buffer gas (He) are introduced through individually calibrated mass flow controllers into a quartz slow flow reactor held at constant pressure and temperature. The gaseous mixture effuses through a 650 μm pinhole into a 1.5 mm skimmer, forming a molecular beam that enters a differentially pumped ionizing chamber. The molecular beam is orthogonally intersected by a tunable synchrotron radiation produced by the ALS in the 8-11 eV energy range. Resultant ions are accelerated, collimated, and focused into an orthogonal time-of-flight mass spectrometer. Reaction species are identified by their mass-to-charge ratios and photoionization (PI) spectra. Comparison of experimental PI spectra with literature and/or simulated curves is routinely done to assure the identity of a given species. With the aid of electronic structure calculations, potential energy surface scans are performed, and Franck-Condon spectral simulations are obtained.

One of these issues is the quality of the air we breathe in the most diverse environments in which we are inserted in an everyday. It is plausible to suppose that, at times like this, there is apprehension regarding the possibility of contamination by pathological agents such as viruses and bacterias through the airways. However, the renewal of indoor air, combined with a properly sanitized air conditioning system, are important tools for the prevention of viral diseases, as is the case with COVID-19. The bus is an example of an environment where renovation is applied to improve the quality of indoor air, helping to reduce the possibility of spreading pathological agents. Together with other care, such as an alcohol gel dispenser, curtains to separate the passengers, cleaning the environment more frequently, and mandatory use of masks, help to reduce the transmission of pathologies, such as COVID-19. Knowing the reality of a large part of the population regarding the need for public transport, there are standards and devices dedicated to promoting air quality, ensuring greater comfort and safety for users. This paper seeks to present such standards and recommendations to improve the quality of indoor air, as well as the equipment responsible for the renewal of the air in the body of a bus. Experimental measurement of the flow rates of the renewal devices present in the bus body allows quantifying the average volume of external air admitted in each type of body. This way, it was possible to compare, in terms of airflow per person, the values of a bus in relation to a series of other environments, using recommendations for air renewal are described through the Brazilian standard ABNT NBR 16401. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20quality" title="air quality">air quality</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20renewal" title=" air renewal"> air renewal</a>, <a href="https://publications.waset.org/abstracts/search?q=buses" title=" buses"> buses</a>, <a href="https://publications.waset.org/abstracts/search?q=Covid-19" title=" Covid-19"> Covid-19</a> </p> <a href="https://publications.waset.org/abstracts/144107/systems-for-air-renewal-inside-bus-bodies-importance-in-the-prevention-of-disease-transmission" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144107.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">151</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> Electricity Load Modeling: An Application to Italian Market</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Masala">Giovanni Masala</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefania%20Marica"> Stefania Marica</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Forecasting electricity load plays a crucial role regards decision making and planning for economical purposes. Besides, in the light of the recent privatization and deregulation of the power industry, the forecasting of future electricity load turned out to be a very challenging problem. Empirical data about electricity load highlights a clear seasonal behavior (higher load during the winter season), which is partly due to climatic effects. We also emphasize the presence of load periodicity at a weekly basis (electricity load is usually lower on weekends or holidays) and at daily basis (electricity load is clearly influenced by the hour). Finally, a long-term trend may depend on the general economic situation (for example, industrial production affects electricity load). All these features must be captured by the model. The purpose of this paper is then to build an hourly electricity load model. The deterministic component of the model requires non-linear regression and Fourier series while we will investigate the stochastic component through econometrical tools. The calibration of the parameters’ model will be performed by using data coming from the Italian market in a 6 year period (2007- 2012). Then, we will perform a Monte Carlo simulation in order to compare the simulated data respect to the real data (both in-sample and out-of-sample inspection). The reliability of the model will be deduced thanks to standard tests which highlight a good fitting of the simulated values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ARMA-GARCH%20process" title="ARMA-GARCH process">ARMA-GARCH process</a>, <a href="https://publications.waset.org/abstracts/search?q=electricity%20load" title=" electricity load"> electricity load</a>, <a href="https://publications.waset.org/abstracts/search?q=fitting%20tests" title=" fitting tests"> fitting tests</a>, <a href="https://publications.waset.org/abstracts/search?q=Fourier%20series" title=" Fourier series"> Fourier series</a>, <a href="https://publications.waset.org/abstracts/search?q=Monte%20Carlo%20simulation" title=" Monte Carlo simulation"> Monte Carlo simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=non-linear%20regression" title=" non-linear regression"> non-linear regression</a> </p> <a href="https://publications.waset.org/abstracts/11709/electricity-load-modeling-an-application-to-italian-market" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11709.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">395</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">22</span> A Radiomics Approach to Predict the Evolution of Prostate Imaging Reporting and Data System Score 3/5 Prostate Areas in Multiparametric Magnetic Resonance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Natascha%20C.%20D%27Amico">Natascha C.

Methods and Materials: 24 cases undergoing multiparametric prostate MR and biopsy were admitted to this pilot study. Clinical outcome of the PI-RADS 3/5 was found through biopsy, finding 8 malignant tumours. The analysed images were acquired with a Philips achieva 1.5T machine with a CE- T2-weighted sequence in the axial plane. Semi-automatic tumour segmentation was carried out on MR images using 3DSlicer image analysis software. 45 shape-based, intensity-based and texture-based features were extracted and represented the input for preprocessing. An evolutionary algorithm (a TWIST system based on KNN algorithm) was used to subdivide the dataset into training and testing set and select features yielding the maximal amount of information. After this pre-processing 20 input variables were selected and different machine learning systems were used to develop a predictive model based on a training testing crossover procedure. Results: The best machine learning system (three-layers feed-forward neural network) obtained a global accuracy of 90% ( 80 % sensitivity and 100% specificity ) with a ROC of 0.82. Conclusion: Machine learning systems coupled with radiomics show a promising potential in distinguishing benign from malign tumours in PI-RADS 3/5 areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title="machine learning">machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=MR%20prostate" title=" MR prostate"> MR prostate</a>, <a href="https://publications.waset.org/abstracts/search?q=PI-Rads%203" title=" PI-Rads 3"> PI-Rads 3</a>, <a href="https://publications.waset.org/abstracts/search?q=radiomics" title=" radiomics"> radiomics</a> </p> <a href="https://publications.waset.org/abstracts/84292/a-radiomics-approach-to-predict-the-evolution-of-prostate-imaging-reporting-and-data-system-score-35-prostate-areas-in-multiparametric-magnetic-resonance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84292.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">188</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> Optimum Turbomachine Preliminary Selection for Power Regeneration in Vapor Compression Cool Production Plants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sayyed%20Benyamin%20Alavi">Sayyed Benyamin Alavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Cerri"> Giovanni Cerri</a>, <a href="https://publications.waset.org/abstracts/search?q=Leila%20Chennaoui"> Leila Chennaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Ambra%20Giovannelli"> Ambra Giovannelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefano%20Mazzoni"> Stefano Mazzoni </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Primary energy consumption and emissions of pollutants (including CO2) sustainability call to search methodologies to lower power absorption for unit of a given product. Cool production plants based on vapour compression are widely used for many applications: air conditioning, food conservation, domestic refrigerators and freezers, special industrial processes, etc. In the field of cool production, the amount of Yearly Consumed Primary Energy is enormous, thus, saving some percentage of it, leads to big worldwide impact in the energy consumption and related energy sustainability. Among various techniques to reduce power required by a Vapour Compression Cool Production Plant (VCCPP), the technique based on Power Regeneration by means of Internal Direct Cycle (IDC) will be considered in this paper. Power produced by IDC reduces power need for unit of produced Cool Power by the VCCPP. The paper contains basic concepts that lead to develop IDCs and the proposed options to use the IDC Power. Among various selections for using turbo machines, Best Economically Available Technologies (BEATs) have been explored. Based on vehicle engine turbochargers, they have been taken into consideration for this application. According to BEAT Database and similarity rules, the best turbo machine selection leads to the minimum nominal power required by VCCPP Main Compressor. Results obtained installing the prototype in “ad hoc” designed test bench will be discussed and compared with the expected performance.

Climate models project scenarios of precipitation changes in the future, considering greenhouse emissions. In this study, the EURO-CORDEX (European Coordinated Regional Downscaling Experiment) climate models were first evaluated in a Mediterranean island (Sardinia) against observed precipitation for a historical reference period (1976-2005). A weighted multi-model ensemble (ENS) was built, weighting the single models based on their ability to reproduce observed rainfall. Future projections (2071-2100) were carried out using the 8.5 RCP emissions scenario to evaluate changes in precipitations. ENS was then used as climate forcing for the SWAT model (Soil and Water Assessment Tool), with the aim to assess the consequences of such projected changes on streamflow and runoff of two small catchments located in the South-West Sardinia. Results showed that a decrease of mean rainfall values, up to -25 % at yearly scale, is expected for the future, along with an increase of extreme precipitation events. Particularly in the eastern and southern areas, extreme events are projected to increase by 30%. Such changes reflect on the hydrologic cycle with a decrease of mean streamflow and runoff, except in spring, when runoff is projected to increase by 20-30%. These results stress that the Mediterranean is a hotspot for climate change, and the use of model tools can provide very useful information to adopt water and land management strategies to deal with such changes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EURO-CORDEX" title="EURO-CORDEX">EURO-CORDEX</a>, <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=hydrology" title=" hydrology"> hydrology</a>, <a href="https://publications.waset.org/abstracts/search?q=SWAT%20model" title=" SWAT model"> SWAT model</a>, <a href="https://publications.waset.org/abstracts/search?q=Sardinia" title=" Sardinia"> Sardinia</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-model%20ensemble" title=" multi-model ensemble"> multi-model ensemble</a> </p> <a href="https://publications.waset.org/abstracts/141817/climate-change-effects-in-a-mediterranean-island-and-streamflow-changes-for-a-small-basin-using-euro-cordex-regional-climate-simulations-combined-with-the-swat-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141817.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">213</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> Application of Homer Optimization to Investigate the Prospects of Hybrid Renewable Energy System in Rural Area: Case of Rwanda</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emile%20Niringiyimana">Emile Niringiyimana</a>, <a href="https://publications.waset.org/abstracts/search?q=LI%20Ji%20Qing"> LI Ji Qing</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Dushimimana"> Giovanni Dushimimana</a>, <a href="https://publications.waset.org/abstracts/search?q=Virginie%20Umwere"> Virginie Umwere</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development and utilization of renewable energy (RE) can not only effectively reduce carbon dioxide (CO2) emissions, but also became a solution to electricity shortage mitigation in rural areas. Hybrid RE systems are promising ways to provide consistent and continuous power for isolated areas. This work investigated the prospect and cost effectiveness of hybrid system complementarity between a 100kW solar PV system and a small-scale 200kW hydropower station in the South of Rwanda. In order to establish the optimal size of a RE system with adequate sizing of system components, electricity demand, solar radiation, hydrology, climate data are utilized as system input. The average daily solar radiation in Rukarara is 5.6 kWh/m2 and average wind speed is 3.5 m/s. The ideal integrated RE system, according to Homer optimization, consists of 91.21kW PV, 146kW hydropower, 12 x 24V li-ion batteries with a 20kW converter. The method of enhancing such hybrid systems control, sizing and choice of components is to reduce the Net present cost (NPC) of the system, unmet load, the cost of energy and reduction of CO2. The power consumption varies according to dominant source of energy in the system by controlling the energy compensation depending on the generation capacity of each power source. The initial investment of the RE system is $977,689.25, and its operation and maintenance expenses is $142,769.39 over a 25-year period. Although the investment is very high, the targeted profits in future are huge, taking into consideration of high investment in rural electrification structure implementations, tied with an increase of electricity cost and the 5 years payback period. The study outcomes suggest that the standalone hybrid PV-Hydropower system is feasible with zero pollution in Rukara community. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HOMER%20optimization" title="HOMER optimization">HOMER optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20power%20system" title=" hybrid power system"> hybrid power system</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=NPC%20and%20solar%20pv%20systems" title=" NPC and solar pv systems"> NPC and solar pv systems</a> </p> <a href="https://publications.waset.org/abstracts/178977/application-of-homer-optimization-to-investigate-the-prospects-of-hybrid-renewable-energy-system-in-rural-area-case-of-rwanda" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178977.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">61</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> River Habitat Modeling for the Entire Macroinvertebrate Community</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pinna%20Beatrice.">Pinna Beatrice.</a>, <a href="https://publications.waset.org/abstracts/search?q=Laini%20Alex"> Laini Alex</a>, <a href="https://publications.waset.org/abstracts/search?q=Negro%20Giovanni"> Negro Giovanni</a>, <a href="https://publications.waset.org/abstracts/search?q=Burgazzi%20Gemma"> Burgazzi Gemma</a>, <a href="https://publications.waset.org/abstracts/search?q=Viaroli%20Pierluigi"> Viaroli Pierluigi</a>, <a href="https://publications.waset.org/abstracts/search?q=Vezza%20Paolo"> Vezza Paolo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Habitat models rarely consider macroinvertebrates as ecological targets in rivers. Available approaches mainly focus on single macroinvertebrate species, not addressing the ecological needs and functionality of the entire community. This research aimed to provide an approach to model the habitat of the macroinvertebrate community. The approach is based on the recently developed Flow-T index, together with a Random Forest (RF) regression, which is employed to apply the Flow-T index at the meso-habitat scale. Using different datasets gathered from both field data collection and 2D hydrodynamic simulations, the model has been calibrated in the Trebbia river (2019 campaign), and then validated in the Trebbia, Taro, and Enza rivers (2020 campaign). The three rivers are characterized by a braiding morphology, gravel riverbeds, and summer low flows. The RF model selected 12 mesohabitat descriptors as important for the macroinvertebrate community. These descriptors belong to different frequency classes of water depth, flow velocity, substrate grain size, and connectivity to the main river channel. The cross-validation R² coefficient (R²𝒸ᵥ) of the training dataset is 0.71 for the Trebbia River (2019), whereas the R² coefficient for the validation datasets (Trebbia, Taro, and Enza Rivers 2020) is 0.63. The agreement between the simulated results and the experimental data shows sufficient accuracy and reliability. The outcomes of the study reveal that the model can identify the ecological response of the macroinvertebrate community to possible flow regime alterations and to possible river morphological modifications. Lastly, the proposed approach allows extending the MesoHABSIM methodology, widely used for the fish habitat assessment, to a different ecological target community. Further applications of the approach can be related to flow design in both perennial and non-perennial rivers, including river reaches in which fish fauna is absent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ecological%20flows" title="ecological flows">ecological flows</a>, <a href="https://publications.waset.org/abstracts/search?q=macroinvertebrate%20community" title=" macroinvertebrate community"> macroinvertebrate community</a>, <a href="https://publications.waset.org/abstracts/search?q=mesohabitat" title=" mesohabitat"> mesohabitat</a>, <a href="https://publications.waset.org/abstracts/search?q=river%20habitat%20modeling" title=" river habitat modeling"> river habitat modeling</a> </p> <a href="https://publications.waset.org/abstracts/164056/river-habitat-modeling-for-the-entire-macroinvertebrate-community" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164056.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">94</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> Coupling Static Multiple Light Scattering Technique With the Hansen Approach to Optimize Dispersibility and Stability of Particle Dispersions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guillaume%20Lemahieu">Guillaume Lemahieu</a>, <a href="https://publications.waset.org/abstracts/search?q=Matthias%20Sentis"> Matthias Sentis</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Brambilla"> Giovanni Brambilla</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%A9rard%20Meunier"> Gérard Meunier</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Static Multiple Light Scattering (SMLS) has been shown to be a straightforward technique for the characterization of colloidal dispersions without dilution, as multiply scattered light in backscattered and transmitted mode is directly related to the concentration and size of scatterers present in the sample. In this view, the use of SMLS for stability measurement of various dispersion types has already been widely described in the literature. Indeed, starting from a homogeneous dispersion, the variation of backscattered or transmitted light can be attributed to destabilization phenomena, such as migration (sedimentation, creaming) or particle size variation (flocculation, aggregation). In a view to investigating more on the dispersibility of colloidal suspensions, an experimental set-up for “at the line” SMLS experiment has been developed to understand the impact of the formulation parameters on particle size and dispersibility. The SMLS experiment is performed with a high acquisition rate (up to 10 measurements per second), without dilution, and under direct agitation. Using such experimental device, SMLS detection can be combined with the Hansen approach to optimize the dispersing and stabilizing properties of TiO₂ particles. It appears that the dispersibility and the stability spheres generated are clearly separated, arguing that lower stability is not necessarily a consequence of poor dispersibility. Beyond this clarification, this combined SMLS-Hansen approach is a major step toward the optimization of dispersibility and stability of colloidal formulations by finding solvents having the best compromise between dispersing and stabilizing properties. Such study can be intended to find better dispersion media, greener and cheaper solvents to optimize particles suspensions, reduce the content of costly stabilizing additives or satisfy product regulatory requirements evolution in various industrial fields using suspensions (paints & inks, coatings, cosmetics, energy). <p class="card-text"><strong>Keywords:</strong> <a
