activities are necessary to ensure the correct functioning of infrastructures. Unmanned Aerial Vehicle (UAV) techniques have become more popular than traditional techniques. Specifically, UAV Photogrammetry allows time and cost savings. The development of this technology has permitted the use of low-cost thermal sensors in UAVs. The representation of 3D thermal models with this type of equipment is in continuous evolution. The direct processing of thermal images usually leads to errors and inaccurate results. A methodology is proposed for the generation of 3D thermal models using dual sensors, which involves the application of visible Red-Blue-Green (RGB) and thermal images in parallel. Hence, the RGB images are used as the basis for the generation of the model geometry, and the thermal images are the source of the surface temperature information that is projected onto the model. Mining/industrial facilities representations that are obtained can be used for inspection activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerial%20thermography" title="aerial thermography">aerial thermography</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20processing" title=" data processing"> data processing</a>, <a href="https://publications.waset.org/abstracts/search?q=drone" title=" drone"> drone</a>, <a href="https://publications.waset.org/abstracts/search?q=low-cost" title=" low-cost"> low-cost</a>, <a href="https://publications.waset.org/abstracts/search?q=point%20cloud" title=" point cloud"> point cloud</a> </p> <a href="https://publications.waset.org/abstracts/148302/application-methodology-for-the-generation-of-3d-thermal-models-using-uav-photogrammety-and-dual-sensors-for-miningindustrial-facilities-inspection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148302.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">143</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">580</span> Analysis of the Accuracy of Earth Movement with Drone Surveys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ra%C3%BAl%20Pereda%20Garc%C3%ADa">Raúl Pereda García</a>, <a href="https://publications.waset.org/abstracts/search?q=Julio%20Manuel%20de%20Luis%20Ruiz"> Julio Manuel de Luis Ruiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Elena%20Castillo%20L%C3%B3pez"> Elena Castillo López</a>, <a href="https://publications.waset.org/abstracts/search?q=Rub%C3%A9n%20P%C3%A9rez%20%C3%81lvarez"> Rubén Pérez Álvarez</a>, <a href="https://publications.waset.org/abstracts/search?q=Felipe%20Pi%C3%B1a%20Garc%C3%ADa"> Felipe Piña García</a> </p> <p class="card-text"><strong>Abstract:</strong></p> New technologies for the capture of point clouds have experienced a great advance in recent years. In this way, its use has been extended in geomatics, providing measurement solutions that have been popularized without there being, many times, a detailed study of its accuracy. This research focuses on the study of the viability of topographic works with drones incorporating different sensors sensitive to the visible spectrum. The fundamentals have been applied to a road, located in Cantabria (Spain), where a platform extension and the reform of a riprap were being constructed. A total of six flights were made during two months, all of them with GPS as part of the photogrammetric process, and the results were contrasted with those measured with total station. The obtained results show that the choice of the camera and the planning of the flight have an important impact on the accuracy. In fact, the representations with a level of detail corresponding to 1/1000 scale are admissible, depending on the existing vegetation, and obtaining better results in the area of the riprap. This set of techniques is, therefore, suitable for the control of earthworks in road works but with certain limitations which are exposed in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drone" title="drone">drone</a>, <a href="https://publications.waset.org/abstracts/search?q=earth%20movement%20control" title=" earth movement control"> earth movement control</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20position%20system" title=" global position system"> global position system</a>, <a href="https://publications.waset.org/abstracts/search?q=surveying%20technology." title=" surveying technology.

One of the main applications is focused on the surveying field. In this regard, software programs that process the images captured by the sensor from the drone in an almost automatic way have been developed and commercialized, but they only allow contrasting the results through control points. This work proposes the contrast of a 3D model obtained from a flight developed by a drone and a non-metric camera (due to its low cost), with a second model that is obtained by means of the historically-endorsed classical methods. In addition to this, the contrast is developed over a certain territory with a significant unevenness, so as to test the model generated with photogrammetry, and considering that photogrammetry with drones finds more difficulties in terms of accuracy in this kind of situations. Distances, heights, surfaces and volumes are measured on the basis of the 3D models generated, and the results are contrasted. The differences are about 0.2% for the measurement of distances and heights, 0.3% for surfaces and 0.6% when measuring volumes. Although they are not important, they do not meet the order of magnitude that is presented by salespeople. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accuracy" title="accuracy">accuracy</a>, <a href="https://publications.waset.org/abstracts/search?q=classical%20topographic" title=" classical topographic"> classical topographic</a>, <a href="https://publications.waset.org/abstracts/search?q=model%20tridimensional" title=" model tridimensional"> model tridimensional</a>, <a href="https://publications.waset.org/abstracts/search?q=photogrammetry" title=" photogrammetry"> photogrammetry</a>, <a href="https://publications.waset.org/abstracts/search?q=Uav." title=" Uav.

In this sense, the classic 3D models are being applied to investigate the direction towards which the generally subterranean structures of an archaeological site may continue and therefore, to help in making the decisions that define the location of new excavations. In recent years, Unmanned Aerial Vehicles (UAVs) have been applied as the vehicles that carry the sensor. This implies certain advantages, such as the possibility of including low-cost sensors, given that these vehicles can carry the sensor at relatively low altitudes. Due to this, low-cost dual sensors have recently begun to be used. This new equipment can collaborate with classic Digital Elevation Models (DEMs) in the exploration of archaeological sites, but this entails the need for a methodological setting to optimise the acquisition, processing and exploitation of the information provided by low-cost dual sensors. This research focuses on the design of an appropriate workflow to obtain 3D models with low-cost sensors carried on UAVs, both in the RGB and thermal domains. All the foregoing has been applied to the archaeological site of Juliobriga, located in Cantabria (Spain). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=process%20optimization" title="process optimization">process optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=RGB%20models" title=" RGB models"> RGB models</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20models" title=" thermal models"> thermal models</a>, <a href="https://publications.waset.org/abstracts/search?q=" title=" "> </a>, <a href="https://publications.waset.org/abstracts/search?q=UAV" title=" UAV"> UAV</a>, <a href="https://publications.waset.org/abstracts/search?q=workflow" title=" workflow"> workflow</a> </p> <a href="https://publications.waset.org/abstracts/137056/generation-of-3d-models-obtained-with-low-cost-rgb-and-thermal-sensors-mounted-on-drones" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137056.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">138</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">577</span> Heavy Metals Estimation in Coastal Areas Using Remote Sensing, Field Sampling and Classical and Robust Statistic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elena%20Castillo-L%C3%B3pez">Elena Castillo-López</a>, <a href="https://publications.waset.org/abstracts/search?q=Ra%C3%BAl%20Pereda"> Raúl Pereda</a>, <a href="https://publications.waset.org/abstracts/search?q=Julio%20Manuel%20de%20Luis"> Julio Manuel de Luis</a>, <a href="https://publications.waset.org/abstracts/search?q=Rub%C3%A9n%20P%C3%A9rez"> Rubén Pérez</a>, <a href="https://publications.waset.org/abstracts/search?q=Felipe%20Pi%C3%B1a"> Felipe Piña</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sediments are an important source of accumulation of toxic contaminants within the aquatic environment.

Compressive strength tests were conducted at 7, 14, and 28 days to assess the influence of these water types on the structural integrity of the concrete. The results indicate that both brackish and sulfur-rich water significantly reduces concrete strength, while Chade 1 water, though initially enhancing strength, displays variability in long-term performance. These outcomes underscore the importance of optimizing construction practices in regions like Jipijapa, where potable water is scarce, by exploring sustainable alternatives for using non-potable water, thereby conserving limited water resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title="compressive strength">compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=plain%20concrete" title=" plain concrete"> plain concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=sulfur%20water" title=" sulfur water"> sulfur water</a>, <a href="https://publications.waset.org/abstracts/search?q=brackish%20water" title=" brackish water"> brackish water</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title=" water quality"> water quality</a> </p> <a href="https://publications.waset.org/abstracts/189221/evaluation-of-water-quality-on-the-strength-of-simple-concrete-case-study-of-wells-in-jipijapa-manabi-ecuador" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189221.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">35</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">574</span> Evaluating Forecasts Through Stochastic Loss Order</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wilmer%20Osvaldo%20Martinez">Wilmer Osvaldo Martinez</a>, <a href="https://publications.waset.org/abstracts/search?q=Manuel%20Dario%20Hernandez"> Manuel Dario Hernandez</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Manuel%20Julio"> Juan Manuel Julio</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We propose to assess the performance of k forecast procedures by exploring the distributions of forecast errors and error losses. We argue that non systematic forecast errors minimize when their distributions are symmetric and unimodal, and that forecast accuracy should be assessed through stochastic loss order rather than expected loss order, which is the way it is customarily performed in previous work. Moreover, since forecast performance evaluation can be understood as a one way analysis of variance, we propose to explore loss distributions under two circumstances; when a strict (but unknown) joint stochastic order exists among the losses of all forecast alternatives, and when such order happens among subsets of alternative procedures. In spite of the fact that loss stochastic order is stronger than loss moment order, our proposals are at least as powerful as competing tests, and are robust to the correlation, autocorrelation and heteroskedasticity settings they consider. In addition, since our proposals do not require samples of the same size, their scope is also wider, and provided that they test the whole loss distribution instead of just loss moments, they can also be used to study forecast distributions as well. We illustrate the usefulness of our proposals by evaluating a set of real world forecasts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forecast%20evaluation" title="forecast evaluation">forecast evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=stochastic%20order" title=" stochastic order"> stochastic order</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20comparison" title=" multiple comparison"> multiple comparison</a>, <a href="https://publications.waset.org/abstracts/search?q=non%20parametric%20test" title=" non parametric test"> non parametric test</a> </p> <a href="https://publications.waset.org/abstracts/167870/evaluating-forecasts-through-stochastic-loss-order" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167870.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">89</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">573</span> Learning the Dynamics of Articulated Tracked Vehicles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mario%20Gianni">Mario Gianni</a>, <a href="https://publications.waset.org/abstracts/search?q=Manuel%20A.%20Ruiz%20Garcia"> Manuel A.

In addition, the scope and limitations of most of these mechanisms are usually presented by professors only in a theoretical way, which does not help students to understand them adequately. In this work, we focus on the problems found when teaching Evolutionary Algorithms (EAs), which imitate the principles of natural evolution, as a method to solve parameter optimization problems. Although this kind of algorithms can be very powerful to solve relatively complex problems, students often have difficulties to understand how they work, and how to apply them to solve problems in real cases. In this paper, we present two interactive graphical applications which have been specially designed with the aim of making Evolutionary Algorithms easy to be understood by students. Specifically, we present: (i) TSPS, an application able to solve the ”Traveling Salesman Problem”, and (ii) FotEvol, an application able to reconstruct a given image by using Evolution Strategies. The main objective is that students learn how these techniques can be implemented, and the great possibilities they offer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=education" title="education">education</a>, <a href="https://publications.waset.org/abstracts/search?q=evolutionary%20algorithms" title=" evolutionary algorithms"> evolutionary algorithms</a>, <a href="https://publications.waset.org/abstracts/search?q=evolution%20strategies" title=" evolution strategies"> evolution strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=interactive%20learning%20applications" title=" interactive learning applications"> interactive learning applications</a> </p> <a href="https://publications.waset.org/abstracts/38035/understanding-evolutionary-algorithms-through-interactive-graphical-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38035.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">338</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">566</span> Application of Transform Fourier for Dynamic Control of Structures with Global Positioning System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20M.%20de%20Luis%20Ruiz">J.

Although accelerometers or Global Positioning System (GPS) have been applied for the monitoring of structures under exploitation, the dynamic monitoring during the stage of construction is not common. This research analyzes whether GPS data can be applied to certain dynamic geometric controls of evolving structures. The fundamentals of this work were applied to the New Bridge of Cádiz (Spain), a worldwide milestone in bridge building. GPS data were recorded with an interval of 1 second during the erection of segments and turned to the frequency domain with Fourier transform. The vibration period and amplitude were contrasted with those provided by the finite element model, with differences of less than 10%, which is admissible. This process provides a vibration record of the structure with GPS, avoiding specific equipment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fourier%20transform" title="Fourier transform">Fourier transform</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20position%20system" title=" global position system"> global position system</a>, <a href="https://publications.waset.org/abstracts/search?q=operational%20modal%20analysis" title=" operational modal analysis"> operational modal analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20health%20monitoring" title=" structural health monitoring"> structural health monitoring</a> </p> <a href="https://publications.waset.org/abstracts/109068/application-of-transform-fourier-for-dynamic-control-of-structures-with-global-positioning-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109068.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">246</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">565</span> Seismic Behavior of Three-Dimensional Steel Buildings with Post-Tensioned Connections</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manuel%20E.%20Soto-L%C3%B3pez">Manuel E.

The comparison is made in terms of global and local response parameters. The results indicate that the seismic responses in terms of interstory shears, roof displacements, axial load and bending moments are smaller for the buildings with PC connection. The difference is larger for global than for local parameters, which in turn varies from one column location to another. The reason for this improved behavior is that the buildings with PC dissipate more hysteretic energy than those with RC. In addition, unlike the case of buildings with WC, for the PC structures the hysteretic energy is mostly dissipated at the connections, which implies that structural damage in beams and columns is not significant. According to this results, steel buildings with PC are a viable option in highseismicity areas because of their smaller response and self-centering connection capacity as well as the fact that brittle failure is avoided. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inter-story%20drift" title="inter-story drift">inter-story drift</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20time-history%20analysis" title=" nonlinear time-history analysis"> nonlinear time-history analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=post-tensioned%20connections" title=" post-tensioned connections"> post-tensioned connections</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20buildings" title=" steel buildings"> steel buildings</a> </p> <a href="https://publications.waset.org/abstracts/18722/seismic-behavior-of-three-dimensional-steel-buildings-with-post-tensioned-connections" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18722.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">499</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">564</span> Learning through Gaming with Mobile Devices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luis%20Rodrigo%20Valencia%20P%C3%A9rez">Luis Rodrigo Valencia Pérez</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Manuel%20Pe%C3%B1a%20Aguilar"> Juan Manuel Peña Aguilar</a>, <a href="https://publications.waset.org/abstracts/search?q=Adelina%20Morita%20Alexander"> Adelina Morita Alexander</a>, <a href="https://publications.waset.org/abstracts/search?q=Alberto%20Lamadrid%20Alvarez"> Alberto Lamadrid Alvarez</a>, <a href="https://publications.waset.org/abstracts/search?q=H%C3%A9ctor%20Fernando%20Valencia%20P%C3%A9rez"> Héctor Fernando Valencia Pérez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Financial education is among the areas of opportunity in the Spanish-speaking from an early age to high school, through mobile devices such as cell phones and tablets using ludic and fun applications like interactive games, children can learn money management and investment through time, thereby fostering the habit of saving and/or sound management of cash and family business resources, having interaction with an uncontrolled environment such as the involvement of other players in the external decisions of the environment in which the game is play.

In this work, a study of the behavior of self-compacting concrete mixtures under replacement of sand by iron slag from 0.0% to 50.0% of weight and variations of water/cementitious material ratio between 0.3 and 0.5 is presented. Control fresh state tests of Slump flow, T500, J-ring and L-box were determined. In the hardened state, compressive strength was determined and optimization from response surface analysis was performed. The study of the variables in the hardened state was developed based on inferential statistical analyses using central composite design methodology and posterior analyses of variance (ANOVA). An increase in the compressive strength up to 50% higher than control mixtures at 7, 14, and 28 days of maturity was the most relevant result regarding the presence of iron slag as replacement of natural sand. Considering the obtained result, it is possible to infer that iron slag is an acceptable alternative replacement material of the natural fine aggregate to be used in structural concrete. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ANOVA" title="ANOVA">ANOVA</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20slag" title=" iron slag"> iron slag</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20surface%20analysis" title=" response surface analysis"> response surface analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=self-compacting%20concrete" title=" self-compacting concrete"> self-compacting concrete</a> </p> <a href="https://publications.waset.org/abstracts/107251/optimization-in-the-compressive-strength-of-iron-slag-self-compacting-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107251.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">144</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">561</span> Formative Assessment in an Introductory Python Programming Course</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Jos%C3%A9%20N%C3%BA%C3%B1ez-Ruiz">María José Núñez-Ruiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20%C3%81lvarez-Gonz%C3%A1lez"> Luis Álvarez-González</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristian%20Olivares-Rodriguez"> Cristian Olivares-Rodriguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Benjamin%20Lazo-Letelier"> Benjamin Lazo-Letelier</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper begins with some concept of formative assessment and the relationship with learning objective: contents objectives, processes objectives, and metacognitive objectives. Two methodologies are describes Evidence-Based teaching and Question Drive Instruction. To do formative assessments in larges classes a Classroom Response System (CRS) is needed. But most of CRS use only Multiple Choice Questions (MCQ), True/False question, or text entry; however, this is insufficient to formative assessment. To do that a new CRS, call FAMA was developed. FAMA support six types of questions: Choice, Order, Inline choice, Text entry, Associated, and Slider. An experiment participated in 149 students from four engineering careers. For results, Kendall's Range Correlation Analysis and descriptive analysis was done. In conclusion, there is a strong relation between contents question, process questions (ask in formative assessment without a score) and metacognitive questions, asked in summative assessment.

In this sense, the study identifies the enormous scenic richness of the area, the growing demand for leisure activities of the urban centers and the multifunctionality that adds, in a complementary way, the traditional activities that up to now have achieved the quality of life levels. From the application of the 43 interviews and 183 surveys, confirms the fact that the post-visit perception exceeds the expectations of the visitors emerges and affirms that the image that has been projected is attractive and timely. In order to understand how the current model of tourism promoted in the region is working, there is a need to evaluate it in a theoretical-methodological framework considering sustainable development assumptions.

The question of nationalism and identity ascription in Spain has always been a topic of special importance due to the presence in that country of territories where the population emits very different opinions of nationalist sentiment than the rest of Spain. The current situation of sovereignty challenge of Catalonia to the central government exemplifies the importance of the subject matter. In order to analyze this process of interrelation, we use a secondary data mining by applying the multiple correspondence analysis technique (MCA).

From the rheological point of view, polymers have the particularity of being viscoelastic liquids. One of the most common and useful models to describe that behavior is the Upper Convected Maxwell model (UCM). The main characteristic of the polymer used in EOR process is the increase in viscosity which pushes the oil outside of the reservoir. The elasticity could contribute in the drag of the oil that stays in the reservoir. Studying the elastic effect on the oil drop at the pore scale, bring an explanation if the addition of elastic force could mobilize the oil. This research explores if the contraction and expansion of the polymer in the pore scale may increase the elastic behavior of this kind of fluid. For that reason, this work simplified the pore geometry and build two simple geometries with micrometer lengths. Using source terms with the user define a function this work introduces the UCM model in the ANSYS fluent simulator with the purpose of evaluating the elastic effect of the polymer in a contraction and expansion geometry. Also, using the Eulerian multiphase model, this research considers the possibility that extra elastic force will show a deformation effect on the oil; for that reason, this work considers an oil drop on the upper wall of the geometry. Finally, all the simulations exhibit that at the pore scale conditions exist extra vortices at UCM model but is not possible to deform the oil completely and push it outside of the restrictions, also this research find the conditions for the oil displacement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ANSYS%20fluent" title="ANSYS fluent">ANSYS fluent</a>, <a href="https://publications.waset.org/abstracts/search?q=interfacial%20fluids%20mechanics" title=" interfacial fluids mechanics"> interfacial fluids mechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=polymers" title=" polymers"> polymers</a>, <a href="https://publications.waset.org/abstracts/search?q=pore%20scale" title=" pore scale"> pore scale</a>, <a href="https://publications.waset.org/abstracts/search?q=viscoelasticity" title=" viscoelasticity"> viscoelasticity</a> </p> <a href="https://publications.waset.org/abstracts/102196/study-of-the-polymer-elastic-behavior-in-the-displacement-oil-drops-at-pore-scale" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102196.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">132</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">557</span> Antiproliferative Effect of Polyphenols from Crocus sativus L.

This is in contrast to other underutilized parts of the saffron plant as leaves, which represent abundant biomass whose use might help to enhance the sustainability of the saffron crop. Saffron leaves contain significant amounts of phenolic compounds, 7.8 equivalent grams of gallic acid per 100g of extract, and are very promising compounds in terms of exploring novel uses of saffron leaves. Given that phenolic compounds have numerous effects on cancer-related biological pathways, we have investigated the in vitro antiproliferative effect of saffron leaf polyphenols against human colon adenocarcinoma cells (Caco-2). Polyphenols were extracted from leaves with 70% ethanol, defatted with hexane, and purified by solid phase extraction using C18 silica gel and then silica gel 60. Analysis of polyphenols was performed by HPLC-ESI-MS. Di-, tri-, and tetrahexosides of quercetin, kaempferol, and isorhamnetin, as well as C-hexosides like isoorientin and vitexin, were tentatively identified. Polyphenols strongly inhibited the proliferation of Caco-2 cells, which is consistent with model studies in which several of the polyphenols identified in saffron leaves have demonstrated their potential as chemopreventive agents in cancer. Due to the low profitability that saffron leaf currently represents, we consider these results very encouraging and that this by-product deserves further investigation as a potential source of active molecules against colorectal cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=saffron%20leaves" title="saffron leaves">saffron leaves</a>, <a href="https://publications.waset.org/abstracts/search?q=agricultural%20by-products" title=" agricultural by-products"> agricultural by-products</a>, <a href="https://publications.waset.org/abstracts/search?q=polyphenols" title=" polyphenols"> polyphenols</a>, <a href="https://publications.waset.org/abstracts/search?q=antiproliferative%20effect" title=" antiproliferative effect"> antiproliferative effect</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20colon%20adenocarcinoma%20cells" title=" human colon adenocarcinoma cells"> human colon adenocarcinoma cells</a> </p> <a href="https://publications.waset.org/abstracts/141891/antiproliferative-effect-of-polyphenols-from-crocus-sativus-l-leaves-on-human-colon-adenocarcinoma-cells-caco-2" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141891.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">556</span> Prediction of the Crustal Deformation of Volcán - Nevado Del RUíz in the Year 2020 Using Tropomi Tropospheric Information, Dinsar Technique, and Neural Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20Sebasti%C3%A1n%20Hern%C3%A1ndez">Juan Sebastián Hernández</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Nevado del Ruíz volcano, located between the limits of the Departments of Caldas and Tolima in Colombia, presented an unstable behaviour in the course of the year 2020, this volcanic activity led to secondary effects on the crust, which is why the prediction of deformations becomes the task of geoscientists. In the course of this article, the use of tropospheric variables such as evapotranspiration, UV aerosol index, carbon monoxide, nitrogen dioxide, methane, surface temperature, among others, is used to train a set of neural networks that can predict the behaviour of the resulting phase of an unrolled interferogram with the DInSAR technique, whose main objective is to identify and characterise the behaviour of the crust based on the environmental conditions. For this purpose, variables were collected, a generalised linear model was created, and a set of neural networks was created. After the training of the network, validation was carried out with the test data, giving an MSE of 0.17598 and an associated r-squared of approximately 0.88454. The resulting model provided a dataset with good thematic accuracy, reflecting the behaviour of the volcano in 2020, given a set of environmental characteristics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crustal%20deformation" title="crustal deformation">crustal deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=Tropomi" title=" Tropomi"> Tropomi</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20networks%20%28ANN%29" title=" neural networks (ANN)"> neural networks (ANN)</a>, <a href="https://publications.waset.org/abstracts/search?q=volcanic%20activity" title=" volcanic activity"> volcanic activity</a>, <a href="https://publications.waset.org/abstracts/search?q=DInSAR" title=" DInSAR"> DInSAR</a> </p> <a href="https://publications.waset.org/abstracts/150005/prediction-of-the-crustal-deformation-of-volcan-nevado-del-ruiz-in-the-year-2020-using-tropomi-tropospheric-information-dinsar-technique-and-neural-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150005.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">103</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">555</span> Attitude towards Doping of High-Performance Athletes in a Sports Institute of the City of Medellin, Colombia </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuban%20Sebastian%20Cuartas-Agudelo">Yuban Sebastian Cuartas-Agudelo</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Marcela%20L%C3%B3pez-Hincapi%C3%A9"> Sandra Marcela López-Hincapié</a>, <a href="https://publications.waset.org/abstracts/search?q=Vivianna%20Alexandra%20Garrido-Altamar"> Vivianna Alexandra Garrido-Altamar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20de%20los%20%C3%81ngeles%20Rodr%C3%ADguez-G%C3%A1zquez"> María de los Ángeles Rodríguez-Gázquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Camilo%20Ruiz-Mej%C3%ADa"> Camilo Ruiz-Mejía</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Mar%C3%ADa%20Mart%C3%ADnez-S%C3%A1nchez"> Lina María Martínez-Sánchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Gloria%20In%C3%A9s%20Mart%C3%ADnez-Dom%C3%ADnguez"> Gloria Inés Martínez-Domínguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Eduardo%20Contreras"> Luis Eduardo Contreras</a>, <a href="https://publications.waset.org/abstracts/search?q=Felipe%20Eduardo%20Marino-Isaza"> Felipe Eduardo Marino-Isaza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Doping is a prohibited practice in competitive sports with potential adverse effects; therefore, it is crucial to describe the attitudes of athletes towards this behavior and to determine which o these increase the susceptibility to carry out this practice. Objective: To determine the attitude of high-performance athletes towards doping in a sports institute in the city of Medellin, Colombia. Methods: We performed a cross-sectional study during 2016, with a sample taken to convenience consisting of athletes over 18 years old enrolled in a sports institute of the city of Medellin (Colombia). The athletes filled by themselves the Petroczi and Aidman questionnaire: Performance Enhancement Attitude Scale (PEAS) adapted to the Spanish language by Morente-Sánchez et al. This scale has 17 items with likert answer options, with a score ranging from 1 to 6, with a higher score indicating a stronger tendency towards doping practices. Results: 112 athletes were included with an average age of 21.6 years old, a 60% of them were male and the most frequent sports were karate 17%, judo 12.5% and athletics 9.8%. The average score of the questionnaire was 35.5 points of a 102 possible points. The lowest score was obtained in the following items: Is Doping necessary 1,4 and Doping isn’t cheating, everyone does it 1,5. Conclusion: In our population, there is a low tendency towards doping practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sports" title="sports">sports</a>, <a href="https://publications.waset.org/abstracts/search?q=doping%20in%20sports" title=" doping in sports"> doping in sports</a>, <a href="https://publications.waset.org/abstracts/search?q=athletic%20performance" title=" athletic performance"> athletic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=attitude" title=" attitude"> attitude</a> </p> <a href="https://publications.waset.org/abstracts/93827/attitude-towards-doping-of-high-performance-athletes-in-a-sports-institute-of-the-city-of-medellin-colombia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93827.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">230</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">554</span> Using Photogrammetry to Survey the Côa Valley Iron Age Rock Art Motifs: Vermelhosa Panel 3 Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nat%C3%A1lia%20Botica">Natália Botica</a>, <a href="https://publications.waset.org/abstracts/search?q=Lu%C3%ADs%20Lu%C3%ADs"> Luís Luís</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulo%20Bernardes"> Paulo Bernardes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Côa Valley, listed World Heritage since 1998, presents more than 1300 open-air engraved rock panels. The Archaeological Park of the Côa Valley recorded the rock art motifs, testing various techniques based on direct tracing processes on the rock, using natural and artificial lighting. In this work, integrated in the "Open Access Rock Art Repository" (RARAA) project, we present the methodology adopted for the vectorial drawing of the rock art motifs based on orthophotos taken from the photogrammetric survey and 3D models of the rocks. We also present the information system designed to integrate the vector drawing and the characterization data of the motifs, as well as the open access sharing, in order to promote their reuse in multiple areas. The 3D models themselves constitute a very detailed record, ensuring the digital preservation of the rock and iconography. Thus, even if a rock or motif disappears, it can continue to be studied and even recreated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rock%20art" title="rock art">rock art</a>, <a href="https://publications.waset.org/abstracts/search?q=archaeology" title=" archaeology"> archaeology</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20age" title=" iron age"> iron age</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20models" title=" 3D models"> 3D models</a> </p> <a href="https://publications.waset.org/abstracts/164190/using-photogrammetry-to-survey-the-coa-valley-iron-age-rock-art-motifs-vermelhosa-panel-3-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164190.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">83</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">553</span> Long-Range Transport of Biomass Burning Aerosols over South America: A Case Study in the 2019 Amazon Rainforest Wildfires Season</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Angel%20Liduvino%20Vara-Vela">Angel Liduvino Vara-Vela</a>, <a href="https://publications.waset.org/abstracts/search?q=Dirceu%20Luis%20Herdies"> Dirceu Luis Herdies</a>, <a href="https://publications.waset.org/abstracts/search?q=Debora%20Souza%20Alvim"> Debora Souza Alvim</a>, <a href="https://publications.waset.org/abstracts/search?q=Eder%20Paulo%20Vendrasco"> Eder Paulo Vendrasco</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvio%20Nilo%20Figueroa"> Silvio Nilo Figueroa</a>, <a href="https://publications.waset.org/abstracts/search?q=Jayant%20Pendharkar"> Jayant Pendharkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Julio%20Pablo%20Reyes%20Fernandez"> Julio Pablo Reyes Fernandez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biomass-burning episodes are quite common in the central Amazon rainforest and represent a dominant source of aerosols during the dry season, between August and October. The increase in the occurrence of fires in 2019 in the world’s largest biomes has captured the attention of the international community. In particular, a rare and extreme smoke-related event occurred in the afternoon of Monday, August 19, 2019, in the most populous city in the Western Hemisphere, the São Paulo Metropolitan Area (SPMA), located in southeastern Brazil. The sky over the SPMA suddenly blackened, with the day turning into night, as reported by several news media around the world. In order to clarify whether or not the smoke that plunged the SPMA into sudden darkness was related to wildfires in the Amazon rainforest region, a set of 48-hour simulations over South America were performed using the Weather Research and Forecasting with Chemistry (WRF-Chem) model at 20 km horizontal resolution, on a daily basis, during the period from August 16 to August 19, 2019. The model results were satisfactorily compared against satellite-based data products and in situ measurements collected from air quality monitoring sites. Although a very strong smoke transport coming from the Amazon rainforest was observed in the middle of the afternoon on August 19, its impact on air quality over the SPMA took place in upper levels far above the surface, where, conversely, low air pollutant concentrations were observed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amazon%20rainforest" title="Amazon rainforest">Amazon rainforest</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass%20burning%20aerosols" title=" biomass burning aerosols"> biomass burning aerosols</a>, <a href="https://publications.waset.org/abstracts/search?q=S%C3%A3o%20Paulo%20metropolitan%20area" title=" São Paulo metropolitan area"> São Paulo metropolitan area</a>, <a href="https://publications.waset.org/abstracts/search?q=WRF-Chem%20model" title=" WRF-Chem model"> WRF-Chem model</a> </p> <a href="https://publications.waset.org/abstracts/129309/long-range-transport-of-biomass-burning-aerosols-over-south-america-a-case-study-in-the-2019-amazon-rainforest-wildfires-season" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129309.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">138</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">552</span> Relationship Between Health Coverage and Emergency Disease Burden</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karim%20Hajjar">Karim Hajjar</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Lillo"> Luis Lillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Diego%20Martinez"> Diego Martinez</a>, <a href="https://publications.waset.org/abstracts/search?q=Manuel%20Hermosilla"> Manuel Hermosilla</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicholas%20Risko"> Nicholas Risko</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: This study examines the relationship between universal health coverage (UCH) and the burden of emergency diseases at a global level. Methods: Data on Disability-Adjusted Life Years (DALYs) from emergency conditions were extracted from the Institute for Health Metrics and Evaluation (IHME) database for the years 2015 and 2019. Data on UHC, measured using two variables, 1) coverage of essential health services and 2) proportion of population spending more than 10% of household income on out-of-pocket health care expenditure, was extracted from the World Bank Database for years preceding our outcome of interest. Linear regression was performed, analyzing the effect of the UHC variables on the DALYs of emergency diseases, controlling for other variables. Results: A total of 133 countries were included. 44.4% of the analyzed countries had coverage of essential health services index of at least 70/100, and 35.3% had at least 10% of their population spend greater than 10% of their household income on healthcare. For every point increase in the coverage of essential health services index, there was a 13-point reduction in DALYs of emergency medical diseases (95% CI -16, -11). Conversely, for every percent decrease in the population with large household expenditure on healthcare, there was a 0.48 increase in DALYs of emergency medical diseases (95% CI -5.6, 4.7). Conclusions: After adjusting for multiple variables, an increase in coverage of essential health services was significantly associated with improvement in DALYs for emergency conditions. There was, however, no association between catastrophic health expenditure and DALYs. <p class="card-text"><strong>Keywords:</strong> <a
