modifications on peak acceleration, velocity and displacement profiles over the structure due to dynamic soil-structure interaction (DSSI). A shear beam model is used for the structure. Soil-foundation flexibility (inertial interaction) is considered by a set of springs and dashpots at the structure base. Kinematic interaction is considered using transfer functions. Impedance functions are computed using simplified expressions for rigid foundations. The research studies the influence of the slenderness ratio on the value of the peak floor response. It is shown that the modifications of peak floor responses are not the same for acceleration, velocity and displacement. This is opposite to the hypothesis used by methods included in several building codes. Results show that modifications produced by DSSI on different response quantities are not equal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=peak%20floor%20intensities" title="peak floor intensities">peak floor intensities</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20soil-structure%20interaction" title=" dynamic soil-structure interaction"> dynamic soil-structure interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=buildings%20with%20flexible%20base" title=" buildings with flexible base"> buildings with flexible base</a>, <a href="https://publications.waset.org/abstracts/search?q=kinematic%20and%20inertial%20interaction" title=" kinematic and inertial interaction"> kinematic and inertial interaction</a> </p> <a href="https://publications.waset.org/abstracts/65705/peak-floor-response-for-buildings-with-flexible-base" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65705.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">450</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">127</span> The Social and Economic Discourse of Roberto Cochrane Simonsen: The Presence of Americanism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maxwel%20F.%20Silva">Maxwel F.

The main objective of this paper is to analyze the workmanship of the visionary entrepreneur and organic intellectual Roberto Cochrane Simonsen (1889-1948). In the set of speeches, lectures and conferences pronounced by Simonsen, the USA constantly appears like model of civilization. The hypothesis is that, as base of the proposals of industrialization defended by him there was an idea of Americanism that would serve of foundation to a way of thinking and acting. For Simonsen, the construction of a nation is directly related to its industrialization. In his thought, develop the Brazil means to structure the country with rational economic mechanisms.

Actually, most building materials have severe environmental impacts along their production cycle. Professionals enrolled in building design may choice the materials and techniques with less impact among the viable options. This work presents a study about embodied energy in materials of two typical Brazilian constructive alternatives. The construction options considered are reinforced concrete structure and structural masonry. The study was developed for the region of São Leopoldo, southern Brazil. Results indicated that the energy embodied in these two constructive systems is approximately 1.72 GJ•m-2 and 1.26 GJ•m-2, respectively. It may be concluded that the embodied energy is lower in the structural masonry system, with a reduction around to 1/4 in relation to the traditional option. The results can be used to help design decisions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=civil%20construction" title="civil construction">civil construction</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=embodied%20energy" title=" embodied energy"> embodied energy</a>, <a href="https://publications.waset.org/abstracts/search?q=Brazil" title=" Brazil"> Brazil</a> </p> <a href="https://publications.waset.org/abstracts/3983/embodied-energy-in-concrete-and-structural-masonry-on-typical-brazilian-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3983.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">437</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">122</span> Iron(III)-Tosylate Doped PEDOT and PEG: A Nanoscale Conductivity Study of an Electrochemical System with Biosensing Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Giulio%20Rosati">Giulio Rosati</a>, <a href="https://publications.waset.org/abstracts/search?q=Luciano%20Sappia"> Luciano Sappia</a>, <a href="https://publications.waset.org/abstracts/search?q=Rossana%20Madrid"> Rossana Madrid</a>, <a href="https://publications.waset.org/abstracts/search?q=Noemi%20Rozl%C3%B2snik"> Noemi Rozlòsnik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The addition of PEG of different molecular weights has important effects on the physical, electrical and electrochemical properties of iron(III)-tosylate doped PEDOT. This particular polymer can be easily spin coated over plastic discs, optimizing thickness and uniformity of the PEDOT-PEG films. The conductivity and morphological analysis of the hybrid PEDOT-PEG polymer by 4-point probe (4PP), 12-point probe (12PP), and conductive AFM (C-AFM) show strong effects of the PEG doping. Moreover, the conductive films kinetics at the nanoscale, in response to different bias voltages, change radically depending on the PEG molecular weight. The hybrid conductive films show also interesting electrochemical properties, making the PEDOT PEG doping appealing for biosensing applications both for EIS-based and amperometric affinity/catalytic biosensors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atomic%20force%20microscopy" title="atomic force microscopy">atomic force microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=biosensors" title=" biosensors"> biosensors</a>, <a href="https://publications.waset.org/abstracts/search?q=four-point%20probe" title=" four-point probe"> four-point probe</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-films" title=" nano-films"> nano-films</a>, <a href="https://publications.waset.org/abstracts/search?q=PEDOT" title=" PEDOT"> PEDOT</a> </p> <a href="https://publications.waset.org/abstracts/75824/ironiii-tosylate-doped-pedot-and-peg-a-nanoscale-conductivity-study-of-an-electrochemical-system-with-biosensing-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75824.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">343</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">121</span> Industrial Ecology Perspectives of Food Supply Chains: A Framework of Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luciano%20Batista">Luciano Batista</a>, <a href="https://publications.waset.org/abstracts/search?q=Sylvia%20Saes"> Sylvia Saes</a>, <a href="https://publications.waset.org/abstracts/search?q=Nuno%20Fouto"> Nuno Fouto</a>, <a href="https://publications.waset.org/abstracts/search?q=Liam%20Fassam"> Liam Fassam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper introduces the theoretical and methodological basis of an analytical framework conceived with the purpose of bringing industrial ecology perspectives into the core of the underlying disciplines supporting analyses in studies concerned with environmental sustainability aspects beyond the product cycle in a supply chain. Given the pressing challenges faced by the food sector, the framework focuses upon waste minimization through industrial linkages in food supply chains. The combination of industrial ecology practice with basic LCA elements, the waste hierarchy model, and the spatial scale of industrial symbiosis allows the standardization of qualitative analyses and associated outcomes. Such standardization enables comparative analysis not only between different stages of a supply chain, but also between different supply chains. The analytical approach proposed contributes more coherently to the wider circular economy aspiration of optimizing the flow of goods to get the most out of raw materials and cuts wastes to a minimum. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=by-product%20synergy" title="by-product synergy">by-product synergy</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20supply%20chain" title=" food supply chain"> food supply chain</a>, <a href="https://publications.waset.org/abstracts/search?q=industrial%20ecology" title=" industrial ecology"> industrial ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=industrial%20symbiosis" title=" industrial symbiosis"> industrial symbiosis</a> </p> <a href="https://publications.waset.org/abstracts/20036/industrial-ecology-perspectives-of-food-supply-chains-a-framework-of-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20036.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">420</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">120</span> Finite Element Analysis of the Blanking and Stamping Processes of Nuclear Fuel Spacer Grids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rafael%20Oliveira%20Santos">Rafael Oliveira Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Luciano%20Pessanha%20Moreira"> Luciano Pessanha Moreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Costa%20Cardoso"> Marcelo Costa Cardoso</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Spacer grid assembly supporting the nuclear fuel rods is an important concern in the design of structural components of a Pressurized Water Reactor (PWR).

A 3D finite element model is also proposed to predict the tooling loads resulting from the stamping process of a preformed Inconel 718 strip and to analyse the residual stress effects upon the spring and dimple design geometries of a nuclear spacer grid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blanking%20process" title="blanking process">blanking process</a>, <a href="https://publications.waset.org/abstracts/search?q=damage%20model" title=" damage model"> damage model</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20modelling" title=" finite element modelling"> finite element modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=inconel%20718" title=" inconel 718"> inconel 718</a>, <a href="https://publications.waset.org/abstracts/search?q=spacer%20grids" title=" spacer grids"> spacer grids</a>, <a href="https://publications.waset.org/abstracts/search?q=stamping%20process" title=" stamping process"> stamping process</a> </p> <a href="https://publications.waset.org/abstracts/35882/finite-element-analysis-of-the-blanking-and-stamping-processes-of-nuclear-fuel-spacer-grids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35882.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">344</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">119</span> Social Work Advocacy Regarding Equitable Hiring Of Latinos</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Roberto%20Lorenzo">Roberto Lorenzo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Much has been said about the dynamics of the Latin American experience in the United States, however, there seems to be very little data regarding the perception of career identity.

Dairy herds are the most affected by heat stress among livestock industries. This clearly implies in development of new strategies for mitigating heat, which should be based on physiological and metabolic adaptations of the animal. In this study, we incorporated the effect of climate variables and heat exposure time on the thermoregulatory responses in order to clarify the adaptive mechanisms for bovine heat dissipation under intense thermal stress induced experimentally in climate chamber. Non-lactating Holstein cows were contemporaneously and randomly assigned to thermoneutral (TN; n=12) or heat stress (HS; n=12) treatments during 16 days. Vaginal temperature (VT) was measured every 15 min with a microprocessor-controlled data logger (HOBO®, Onset Computer Corporation, Bourne, MA, USA) attached to a modified vaginal controlled internal drug release insert (Sincrogest®, Ourofino, Brazil). Rectal temperature (RT), respiratory rate (RR) and heart rate (HR) were measured twice a day (0700 and 1500h) and dry matter intake (DMI) was estimated daily. The ambient temperature and air relative humidity were 25.9±0.2°C and 73.0±0.8%, respectively for TN, and 36.3± 0.3°C and 60.9±0.9%, respectively for HS. Respiratory rate of HS cows increased immediately after exposure to heat and was higher (76.02±1.70bpm; P<0.001) than TN (39.70±0.71bpm), followed by rising of RT (39.87°C±0.07 for HS versus 38.56±0.03°C for TN; P<0.001) and VT (39.82±0.10°C for HS versus 38.26±0.03°C for TN; P<0.001). A diurnal pattern was detected, with higher (P<0.01) afternoon temperatures than morning and this effect was aggravated for HS cows. There was decrease (P<0.05) of HR for HS cows (62.13±0.99bpm) compared to TN (66.23±0.79bpm), but the magnitude of the differences was not the same over time. From the third day, there was a decrease of DMI for HS in attempt to maintain homeothermy, while TN cows increased DMI (8.27kg±0.33kg d-1 for HS versus 14.03±0.29kg d-1 for TN; P<0.001). By regression analysis, RT and RR better reflected the response of cows to changes in the Temperature Humidity Index and the effect of climate variables from the previous day to influence the physiological parameters and DMI was more important than the current day, with ambient temperature the most important factor. Comparison between acute (0 to 3 days) and chronic (13 to 16 days) exposure to heat stress showed decreasing of the slope of the regression equations for RR and DMI, suggesting an adaptive adjustment, however with no change for RT. In conclusion, intense heat stress exerted strong influence on the thermoregulatory mechanisms, but the acclimation process was only partial. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acclimation" title="acclimation">acclimation</a>, <a href="https://publications.waset.org/abstracts/search?q=bovine" title=" bovine"> bovine</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20chamber" title=" climate chamber"> climate chamber</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperthermia" title=" hyperthermia"> hyperthermia</a>, <a href="https://publications.waset.org/abstracts/search?q=thermoregulation" title=" thermoregulation"> thermoregulation</a> </p> <a href="https://publications.waset.org/abstracts/55894/thermoregulatory-responses-of-holstein-cows-exposed-to-intense-heat-stress" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55894.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">218</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">116</span> Magnesium Alloys for Biomedical Applications Processed by Severe Plastic Deformation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mariana%20P.%20Medeiros">Mariana P.

The results show the severe plastic deformation processing improves the strength of all magnesium alloys, but deformation localization can take place in the Mg-Zn-Ca and Mg-Y-RE alloys. The occurrence of deformation localization is associated with low strain rate sensitivity in these alloys and with severe corrosion localization.

Some monuments are well known for their paintings, sometimes associated with engraved motifs, giving the funerary crypts a character of great symbolic value. The engraved and painted motifs, the colors used in the paintings, and the offerings associated with the deposited corpses are archaeological data that, being part of the funeral rites, also reveal the ideological world of these communities and their way of interacting with the world. In this sense, the choice of colors to be used in the paintings, the pigments collected, and the proceeds for making the paints would also be significant performances. The present study will focus on the characterization of painted art from megalithic monuments located in different areas of North-Western Portugal (coastal and inland). The colorant composition of megalithic barrows decorated with rock art motifs was studied using a multi-analytical approach (XRD, SEM-EDS, FTIR, and GC-MS), allowing the characterization of the painting techniques, pigments, and the organic compounds used as binders. Some analyses revealed that the pigments used for painting were produced using a collection of mined or quarried organic and inorganic substances. The results will be analyzed from the perspective of contingencies and regularity among the different case studies in order to interpret more or less standardized behaviors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=funerary%20megalithic%20monuments" title="funerary megalithic monuments">funerary megalithic monuments</a>, <a href="https://publications.waset.org/abstracts/search?q=painting%20motifs" title=" painting motifs"> painting motifs</a>, <a href="https://publications.waset.org/abstracts/search?q=archaeometrical%20studies" title=" archaeometrical studies"> archaeometrical studies</a>, <a href="https://publications.waset.org/abstracts/search?q=Northwest%20Iberia" title=" Northwest Iberia"> Northwest Iberia</a>, <a href="https://publications.waset.org/abstracts/search?q=behaviors" title=" behaviors"> behaviors</a> </p> <a href="https://publications.waset.org/abstracts/159912/painting-in-neolithic-of-northwest-iberia-archaeometrical-studies-applied-to-megalithic-monuments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159912.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">110</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">113</span> Towards a Model of Support in the Areas of Services of Educational Assistance and Mentoring in Middle Education in Mexico</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Margarita%20Zavala">Margarita Zavala</a>, <a href="https://publications.waset.org/abstracts/search?q=Gabriel%20Chavira"> Gabriel Chavira</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Gonz%C3%A1lez"> José González</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Orozco"> Jorge Orozco</a>, <a href="https://publications.waset.org/abstracts/search?q=Julio%20Rol%C3%B3n"> Julio Rolón</a>, <a href="https://publications.waset.org/abstracts/search?q=Roberto%20Pichardo"> Roberto Pichardo </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Adolescence is a neuralgic stage in the formation of every human being, generally this stage is when the middle school level is studied. In 2006, Mexico incorporated 'mentoring' space to assist students in their integration and participation in life. In public middle schools, it is sometimes difficult to be aware of situations that affect students because of the number of them and traditional records management. With this, they lose the opportunity to provide timely support as a preventive way. In order to provide this support, it is required to know the students by detecting the relevant information that has greater impact on their learning process.

We propose in this paper a technique to obtain data consistency with Snapshot by using some special triggers that we named Daemon Triggers. Besides keeping the benefits of the Snapshot isolation, the technique is specially useful for those database systems that do not have an isolation level that ensures serializability, like Firebird and Oracle. We describe all the anomalies that might arise when using the Snapshot isolation and show how to preclude them with Daemon Triggers.

This paper presents a dry relaxation shrinkage prediction of Bordeaux fiber using a feed forward neural network and linear regression models. Six operational alternatives of shrinkage were predicted. A comparison of the results was performed finding neural network models with higher levels of explanation of the variability and prediction. The presence of different reposes are included. The models were obtained through a neural toolbox of Matlab and Minitab software with real data in a knitting company of Southern Guanajuato. The results allow predicting dry relaxation shrinkage of each alternative operation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neural%20network" title="neural network">neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=dry%20relaxation" title=" dry relaxation"> dry relaxation</a>, <a href="https://publications.waset.org/abstracts/search?q=knitting" title=" knitting"> knitting</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20regression" title=" linear regression"> linear regression</a> </p> <a href="https://publications.waset.org/abstracts/30179/dry-relaxation-shrinkage-prediction-of-bordeaux-fiber-using-a-feed-forward-neural" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30179.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">585</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">110</span> Towards a Model of Support in the Areas of Services of Educational Assistance and Tutoring in Middle Education in Mexico</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Margarita%20Zavala">Margarita Zavala</a>, <a href="https://publications.waset.org/abstracts/search?q=Julio%20Rol%C3%B3n"> Julio Rolón</a>, <a href="https://publications.waset.org/abstracts/search?q=Gabriel%20Chavira"> Gabriel Chavira</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Gonz%C3%A1lez"> José González</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Orozco"> Jorge Orozco</a>, <a href="https://publications.waset.org/abstracts/search?q=Roberto%20Pichardo"> Roberto Pichardo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Adolescence is a neuralgic stage in the formation of every human being, generally at this stage is when the middle school level is studied. In 2006 in Mexico incorporated “mentoring" space to assist students in their integration and participation in life. In public middle schools, is sometimes difficult to be aware of situations that affect students because of the number of them and traditional records management. Whit this they lose the opportunity to provide timely support as a preventive way. In order to provide this support, it is required to know the students by detecting the relevant information that has greater impact on their learning process. This research is looking to check if it is possible to identify student’s relevant information to detect when it is at risk, and then to propose a model to manage in a proper way such information. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adolescence" title="adolescence">adolescence</a>, <a href="https://publications.waset.org/abstracts/search?q=mentoring" title=" mentoring"> mentoring</a>, <a href="https://publications.waset.org/abstracts/search?q=middle%20school%20students" title=" middle school students"> middle school students</a>, <a href="https://publications.waset.org/abstracts/search?q=mentoring%20system%20support" title=" mentoring system support"> mentoring system support</a> </p> <a href="https://publications.waset.org/abstracts/11203/towards-a-model-of-support-in-the-areas-of-services-of-educational-assistance-and-tutoring-in-middle-education-in-mexico" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11203.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">420</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">109</span> Autism Screening Questionnaire for Daycare Attendees</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20Alejandro%20Torres-Lopez">David Alejandro Torres-Lopez </a>, <a href="https://publications.waset.org/abstracts/search?q=Lilia%20Albores-Gallo"> Lilia Albores-Gallo</a>, <a href="https://publications.waset.org/abstracts/search?q=Ronald%20Soto-Calderon"> Ronald Soto-Calderon</a>, <a href="https://publications.waset.org/abstracts/search?q=Roberto%20Lagunes-Cordoba"> Roberto Lagunes-Cordoba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Autism Screening Questionnaire for Daycare Attendees (ASQ-DAT) is a screening instrument that assesses the risk of autism in children between 12 and 47 months, being the first free observational instrument created according to the criteria of the DSM-5 that can be applied by teachers in nurseries. The people in charge of answering the questionnaires are the daycare assistants. Its application presents a series of previous activities with which daycare assistants are familiar (dance, games, oral narration and breakfast), which are executed with the children and then answer a questionnaire with dichotomous questions "Yes/No" in approximately 3 minutes per child. The instrument was developed with the participation of nurseries according to the protocols of the creation of psychometric instruments of the Classical Test Theory having as a gold standard ADOS-2 Modules T and 1. The results of the investigation show that the use of ASQ-DAT combined with the application of M-CHAT / RF provides more information about the risk of ASD in young children, which allows improvements in the screening. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diagnosis" title="diagnosis">diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=screening" title=" screening"> screening</a>, <a href="https://publications.waset.org/abstracts/search?q=autism" title=" autism"> autism</a>, <a href="https://publications.waset.org/abstracts/search?q=daycare" title=" daycare"> daycare</a> </p> <a href="https://publications.waset.org/abstracts/92545/autism-screening-questionnaire-for-daycare-attendees" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92545.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">219</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">108</span> Omni: Data Science Platform for Evaluate Performance of a LoRaWAN Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emanuele%20A.%20Solagna">Emanuele A.

The evolution of this technology has generated multiple challenges related to the generation of big data and the active participation of electronic devices in society. Thus, devices can send information that is captured and processed over large areas, but there is no guarantee that all the obtained data amount will be effectively stored and correctly persisted. Because, depending on the technology which is used, there are parameters that has huge influence on the full delivery of information.

Artificial intelligence offers the possibility to implement new methods to identify the vessel class type from the kinematic features of the vessel itself. The task strictly depends on the quality of the data. This paper explores the application of a deep, long short-term memory model by using AIS flow only with a relatively low quality. The proposed model reaches high accuracy on detecting nine vessel classes representing the most common vessel types in the Ionian-Adriatic Sea. The model has been applied during the Adriatic-Ionian trial period of the international EU ANDROMEDA H2020 project to identify vessels performing behaviors far from the expected one depending on the declared type. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maritime%20surveillance" title="maritime surveillance">maritime surveillance</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=behavior%20analysis" title=" behavior analysis"> behavior analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=LSTM" title=" LSTM"> LSTM</a> </p> <a href="https://publications.waset.org/abstracts/136953/identification-of-vessel-class-with-long-short-term-memory-using-kinematic-features-in-maritime-traffic-control" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136953.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">231</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">106</span> Pulsed Electric Field as Pretreatment for Different Drying Method in Chilean Abalone (Concholepas Concholepas) Mollusk: Effects on Product Physical Properties and Drying Methods Sustainability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luis%20Gonz%C3%A1lez-Cavieres">Luis González-Cavieres</a>, <a href="https://publications.waset.org/abstracts/search?q=Mario%20Perez-Won"> Mario Perez-Won</a>, <a href="https://publications.waset.org/abstracts/search?q=Anais%20Palma-Acevedo"> Anais Palma-Acevedo</a>, <a href="https://publications.waset.org/abstracts/search?q=Gipsy%20Tabilo-Munizaga"> Gipsy Tabilo-Munizaga</a>, <a href="https://publications.waset.org/abstracts/search?q=Erick%20Jara-Quijada"> Erick Jara-Quijada</a>, <a href="https://publications.waset.org/abstracts/search?q=Roberto%20Lemus-Mondaca"> Roberto Lemus-Mondaca</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, pulsed electric field (PEF: 2.0 kV/cm) was used as pretreatment in drying methods, vacuum microwave (VMD); freeze-drying (FD); and hot air (HAD), in Chilean abalone mollusk.

Sewaybricker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Psychology has faced many challenges in order to claim its right to study happiness. Probably the major issue has been to present a clear definition of happiness, which has a long history outside the scientific field and has been used imprecisely in the daily life. Even after years of great improvement, different meanings of happiness still have been seen in academic studies. This scenario allows to question if any definition is consistent enough to sustain the recent findings of the psychological processes behind happiness. Moreover, does it make sense to seek a single definition of happiness? By investigating the history of happiness and the theoretical foundations of Positive Psychology, it can be advocated that it’s proper for happiness to be polysemic. Since Ancient Greece most attempts to outline happiness consists of an appreciation of the "best way to live" and consequently requires a delineation of the most important things in life. Besides this generic definition, it’s hard to find consensus about happiness. In fact, what and how much something will be considered important to happiness depend on social influence. This compels happiness to vary between groups, historical periods, and even for the same person over time. Therefore, the same psychological processes will not necessarily be behind all forms of happiness. Consequently, three assumptions should be considered when studying happiness: it’s intrinsic of happiness to be transitory and socially influenced; happiness refers not only to what is possible in the present, but also to an ideal future; when someone (including a scientist) talks about happiness they describe and prescribe a better way to live. Because any attempt to define happiness will be limited in space and time, it's more suitable to study its variations than its universalities. This may have considerable consequences to political agenda on happiness evaluation and maximization, like Gross National Happiness and utilitarian initiatives. Happiness policies should be understood as an arbitrary choice amongst all kinds of happiness and as prescriptive of what “the best way to live” should be. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=happiness" title="happiness">happiness</a>, <a href="https://publications.waset.org/abstracts/search?q=politics" title=" politics"> politics</a>, <a href="https://publications.waset.org/abstracts/search?q=positive%20psychology" title=" positive psychology"> positive psychology</a>, <a href="https://publications.waset.org/abstracts/search?q=well-being" title=" well-being"> well-being</a> </p> <a href="https://publications.waset.org/abstracts/23322/happiness-and-its-political-consequences-a-proposal-for-a-socially-constructed-object" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23322.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">258</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">104</span> Nazi Experiments during World War II: Dismal Period for Bioethics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Catharina%20O.%20Vianna%20Dias%20da%20Silva">Catharina O.

The method was based on the bibliographic review of articles published in databases such as SciELO and Pubmed. In the discussion, historical and humanistic aspects that contributed to the construction of a genocidal culture practiced during this period were analyzed. Additionally, an ethical question arises: should the information acquired during this dark period be used by science? After analysis, it was found that these Nazi experiments went over medical and ethical principles, being a deplorable milestone in history. It was also concluded that, although they generated potentially 'useful' results in the scientific field, they should be discarded as an ethical question of principle, of never daring to validate such a deplorable way of obtaining knowledge. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nazism" title="Nazism">Nazism</a>, <a href="https://publications.waset.org/abstracts/search?q=bioethics" title=" bioethics"> bioethics</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20experimentation" title=" human experimentation"> human experimentation</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20rights" title=" human rights"> human rights</a>, <a href="https://publications.waset.org/abstracts/search?q=genocide" title=" genocide"> genocide</a>, <a href="https://publications.waset.org/abstracts/search?q=torture" title=" torture"> torture</a>, <a href="https://publications.waset.org/abstracts/search?q=medicine" title=" medicine"> medicine</a> </p> <a href="https://publications.waset.org/abstracts/133246/nazi-experiments-during-world-war-ii-dismal-period-for-bioethics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133246.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">171</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">103</span> Recovery of an Area Degraded by Gullies in the Municipality of Monte Alto (SP), Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Layane%20Sara%20Vieira">Layane Sara Vieira</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulo%20Egidio%20Bernardo"> Paulo Egidio Bernardo</a>, <a href="https://publications.waset.org/abstracts/search?q=Roberto%20Saverio%20Souza%20Costa"> Roberto Saverio Souza Costa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Anthropogenic occupations and agricultural explorations without concern for the preservation and sustainability of the activity result in soil degradation that can make rural activity unfeasible. The objective of this work was to characterize and evaluate the recovery costs of an area degraded by major erosion (gully) in the municipality of Monte Alto (SP). Topographic characterization was carried out by means of a planialtimetric survey with a total station. The contours of the gully, internal area, slope height, contribution area, volume, and costs of operations for the recovery of the gully were delimited. The results obtained showed that the gully has a length of 145.56 m, a maximum width of 36.61 m, and a gap of 19.48 m. The external area of the gully is 1,039.8741 m², and the internal area is 119.3470 m². The calculated volume was 3,282.63 m³. The intervention area for breaking slopes was measured at 8,471.29 m², requiring the construction of 19 terraces in this area, vertically spaced at 2.8 m. The estimated costs for mechanical recovery of the gully were R$ 19,167.84 (US$ 3.657,98). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=erosion" title="erosion">erosion</a>, <a href="https://publications.waset.org/abstracts/search?q=volumetric%20assessment" title=" volumetric assessment"> volumetric assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20degradation" title=" soil degradation"> soil degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=terraces" title=" terraces"> terraces</a> </p> <a href="https://publications.waset.org/abstracts/152776/recovery-of-an-area-degraded-by-gullies-in-the-municipality-of-monte-alto-sp-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152776.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">106</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">102</span> Analysis of the Acoustic Performance of Vertical Internal Seals with Pet Wool as NBR 15.575-4NO Green Towers Building-DF</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lucas%20Aerre">Lucas Aerre</a>, <a href="https://publications.waset.org/abstracts/search?q=Wallesson%20Faria"> Wallesson Faria</a>, <a href="https://publications.waset.org/abstracts/search?q=Roberto%20Pimentel"> Roberto Pimentel</a>, <a href="https://publications.waset.org/abstracts/search?q=Juliana%20Santos"> Juliana Santos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An extremely disturbing and irritating element in the lives of people and organizations is the noise, the consequences that can bring us has a lot of connection with human health as well as financial and economic aspects. In order to improve the efficiency of buildings in Brazil in general, a performance standard was created, NBR 15.575 in which all buildings are seen in a more systemic and peculiar way, while following the requirements of the standard. The acoustic performance present in these buildings is one such requirement. Based on this, the present work was elaborated with the objective of evaluating through acoustic measurements the acoustic performance of vertical internal fences that are under the incidence of aerial noise of a building in the city of Brasilia-DF. A short theoretical basis is made and soon after the procedures of measurement are described through the control method established by the standard, and its results are evaluated according to the parameters of the same.

In this work, a method for the hot extrusion of a 75.50% Cu, 16,74% Zn, 7,76% Al (weight %) alloy is presented. The effects of the thermomechanical processing in the microstructure and the pseudoelastic behavior of the alloy are assessed by optical metallography, compression and hardness tests. Results show that hot extrusion is a suitable method to obtain severe cross-section reductions in the CuZnAl shape-memory alloy studied. The alloy maintained its pseudoelastic effect after the extrusion and the modifications in the mechanical behavior caused by precipitation during hot extrusion can be minimized by a suitable precipitate dissolution heat treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hot%20extrusion" title="hot extrusion">hot extrusion</a>, <a href="https://publications.waset.org/abstracts/search?q=pseudoelastic" title=" pseudoelastic"> pseudoelastic</a>, <a href="https://publications.waset.org/abstracts/search?q=shape-memory%20alloy" title=" shape-memory alloy"> shape-memory alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=thermomechanical%20processing" title=" thermomechanical processing"> thermomechanical processing</a> </p> <a href="https://publications.waset.org/abstracts/70427/thermomechanical-processing-of-a-cuznal-shape-memory-alloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70427.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">374</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">100</span> A Real Time Expert System for Decision Support in Nuclear Power Plants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andressa%20dos%20Santos%20Nicolau">Andressa dos Santos Nicolau</a>, <a href="https://publications.waset.org/abstracts/search?q=Jo%C3%A3o%20P.%20da%20S.C%20Algusto"> João P. da S.C Algusto</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudio%20M%C3%A1rcio%20do%20N.%20A.%20Pereira"> Claudio Márcio do N.

In this paper, we proposed a Real Time Expert System in order to improve operator’s performance in case of transient or accident with reactor shutdown. The expert system’s knowledge is based on the sequence of events (SoE) of known accident and two emergency procedures of the Brazilian Pressurized Water Reactor (PWR) NPP and uses two kinds of knowledge representation: rule and logic trees. The results show that the system was able to classify the response of the automatic protection systems, as well as to evaluate the conditions of the plant, diagnosing the type of occurrence, recovery procedure to be followed, indicating the shutdown root cause, and classifying the emergency level. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emergence%20procedure" title="emergence procedure">emergence procedure</a>, <a href="https://publications.waset.org/abstracts/search?q=expert%20system" title=" expert system"> expert system</a>, <a href="https://publications.waset.org/abstracts/search?q=operator%20support" title=" operator support"> operator support</a>, <a href="https://publications.waset.org/abstracts/search?q=PWR%20nuclear%20power%20plant" title=" PWR nuclear power plant"> PWR nuclear power plant</a> </p> <a href="https://publications.waset.org/abstracts/67426/a-real-time-expert-system-for-decision-support-in-nuclear-power-plants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67426.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">333</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">99</span> Forming Limit Analysis of DP600-800 Steels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Costa%20Cardoso">Marcelo Costa Cardoso</a>, <a href="https://publications.waset.org/abstracts/search?q=Luciano%20Pessanha%20Moreira"> Luciano Pessanha Moreira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, the plastic behaviour of cold-rolled zinc coated dual-phase steel sheets DP600 and DP800 grades is firstly investigated with the help of uniaxial, hydraulic bulge and Forming Limit Curve (FLC) tests. The uniaxial tensile tests were performed in three angular orientations with respect to the rolling direction to evaluate the strain-hardening and plastic anisotropy. True stress-strain curves at large strains were determined from hydraulic bulge testing and fitted to a work-hardening equation. The limit strains are defined at both localized necking and fracture conditions according to Nakajima’s hemispherical punch procedure. Also, an elasto-plastic localization model is proposed in order to predict strain and stress based forming limit curves. The investigated dual-phase sheets showed a good formability in the biaxial stretching and drawing FLC regions. For both DP600 and DP800 sheets, the corresponding numerical predictions overestimated and underestimated the experimental limit strains in the biaxial stretching and drawing FLC regions, respectively. This can be attributed to the restricted failure necking condition adopted in the numerical model, which is not suitable to describe the tensile and shear fracture mechanisms in advanced high strength steels under equibiaxial and biaxial stretching conditions. <p class="card-text"><strong>Keywords:</strong> <a
