The significance of this work relies on the applicability of this fact to the analysis of small and medium enterprises (SMEs) of dry freight in Bogotá. Two stages constitute this implementation: the first one is the place where optimal planning is achieved through a hybrid model developed with mixed integer programming, which considers the transhipment operation based on a combined load allocation model as a classic transshipment model; the second one is the specific routing of that operation through the heuristics of Clark and Wright. As a result, an integral model is obtained to carry out the step by step planning of the distribution of dry freight for SMEs in Bogotá. In this manner, optimum assignments are established by utilizing transshipment centers with that purpose of determining the specific routing based on the shortest distance traveled. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transshipment%20model" title="transshipment model">transshipment model</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20integer%20programming" title=" mixed integer programming"> mixed integer programming</a>, <a href="https://publications.waset.org/abstracts/search?q=saving%20algorithm" title=" saving algorithm"> saving algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=dry%20freight%20transportation" title=" dry freight transportation"> dry freight transportation</a> </p> <a href="https://publications.waset.org/abstracts/92747/model-of-transhipment-and-routing-applied-to-the-cargo-sector-in-small-and-medium-enterprises-of-bogota-colombia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92747.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">267</span> Forecast Based on an Empirical Probability Function with an Adjusted Error Using Propagation of Error</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oscar%20Javier%20Herrera">Oscar Javier Herrera</a>, <a href="https://publications.waset.org/abstracts/search?q=Manuel%20Angel%20Camacho"> Manuel Angel Camacho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper addresses a cutting edge method of business demand forecasting, based on an empirical probability function when the historical behavior of the data is random.

The use of herbs, garlic, due to the structure and composition of it has beneficial role in human nutrition and animal nutrition. This study was conducted evaluate the effect different levels of garlic (Allium sativum) powder on the some serum biochemical parameters of Oscar fish (Astronotus ocellatus). Fish were divided into four groups fed on diets containing garlic in different levels; 5 g kg˗1, 10 g kg-1, 20 g kg-1, 30 g kg-1 diet and the control group diet was without garlic. A total number of 300 fish was used and Triplicate groups of Oscar fish with initial weight of 12.43±0.24 g were hand-fed to visual satiation at three meals per day. The experiment extended for two months. Total Protein (TP), Albumin (ALB), Globulin (GLB) and Albumin/Globulin (A/G) ratio, were determined. Based on the results, no significant differences were seen among treatments and control groups during the experimental period for TP, ALB, GLB, and A/G ratio (p > 0.05). Although, the highest amount of serum total protein and globulin levels were observed in diet containing 10 g kg-1 of garlic. Also, the highest value of albumin and A/G were observed in diet containing 20 g kg-1 of garlic, but there were no significant difference with other treatments. The results of this study show that addition of garlic Allium sativum to fish diet can improve fish health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=garlic%20%28Allium%20sativum%29" title="garlic (Allium sativum)">garlic (Allium sativum)</a>, <a href="https://publications.waset.org/abstracts/search?q=serum" title=" serum"> serum</a>, <a href="https://publications.waset.org/abstracts/search?q=Oscar%20fish%20%28Astronotus%20ocellatus%29" title=" Oscar fish (Astronotus ocellatus)"> Oscar fish (Astronotus ocellatus)</a>, <a href="https://publications.waset.org/abstracts/search?q=iran" title=" iran"> iran</a> </p> <a href="https://publications.waset.org/abstracts/30416/the-effects-of-garlic-allium-sativum-in-the-diet-on-some-serum-biochemical-parameters-of-oscar-fish-astronotus-ocellatus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30416.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">482</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">263</span> Estimating the Probability of Winning the Best Actor/Actress Award Conditional on the Best Picture Nomination with Bayesian Hierarchical Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Svetlana%20K.%20Eden">Svetlana K. Eden</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Movies and TV shows have long become part of modern culture. We all have our preferred genre, story, actors, and actresses. However, can we objectively discern good acting from the bad? As laymen, we are probably not objective, but what about the Oscar academy members? Are their votes based on objective measures? Oscar academy members are probably also biased due to many factors, including their professional affiliations or advertisement exposure. Heavily advertised films bring more publicity to their cast and are likely to have bigger budgets. Because a bigger budget may also help earn a Best Picture (BP) nomination, we hypothesize that best actor/actress (BA) nominees from BP-nominated movies would have higher chances of winning the award than those BA nominees from non-BP-nominated films. To test this hypothesis, three Bayesian hierarchical models are proposed, and their performance is evaluated. The results from all three models largely support our hypothesis. Depending on the proportion of BP nominations among BA nominees, the odds ratios (estimated over expected) of winning the BA award conditional on BP nomination vary from 2.8 [0.8-7.0] to 4.3 [2.0, 15.8] for actors and from 1.5 [0.0, 12.2] to 5.4 [2.7, 14.2] for actresses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oscar" title="Oscar">Oscar</a>, <a href="https://publications.waset.org/abstracts/search?q=best%20picture" title=" best picture"> best picture</a>, <a href="https://publications.waset.org/abstracts/search?q=best%20actor%2Factress" title=" best actor/actress"> best actor/actress</a>, <a href="https://publications.waset.org/abstracts/search?q=bias" title=" bias"> bias</a> </p> <a href="https://publications.waset.org/abstracts/121657/estimating-the-probability-of-winning-the-best-actoractress-award-conditional-on-the-best-picture-nomination-with-bayesian-hierarchical-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121657.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">223</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">262</span> Effect of Dietary Spirulina Powder on Growth Performance, Body Composition, Hematological, Biological and Immunological Parameters of Oscar Fish, Astronotus ocellatus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Negar%20Ghotbeddin">Negar Ghotbeddin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the changes in survival, growth, body composition, hematological, biochemical and immunological parameters of oscar fish (Astronotus ocellatus) have been investigated with dietary spirulina powder supplementation. Total of 300 fish with an initial weight of 8.37 ± 0.36 was distributed to three treatments and one control (0%). The fish were fed 8 weeks with diets containing different concentrations of S. powder: (control (0%), 2.5%, 5%, and 10%). Then sampling was done, and different parameters were measured by standard methods. Growth performance such as weight gain (%), specific growth rate (SGR) and feed conversion ratio (FCR) significantly improved in fish fed with S. powder (p < 0.5). Crude protein significantly increased in the S. powder supplemented groups (p < 0.5). However, crude lipid decreased with the increasing of dietary S. powder levels. Total protein increased in fish fed with 10% S. powder. Triglycerides and cholesterol decreased with the increasing of dietary S. powder levels. Immunological parameters including C3 and C4 increased significantly with the increasing of dietary S. powder levels, and lysozyme was improved in 10% S. powder.

This situation does not allow a proper disposal of this type of waste, which in turn results in a negative impact on the environment. Therefore, through the comparative analysis of various heuristics, the best solution to the VRP (Vehicle Routing Problem) was selected by comparing costs and times for the collection of used lubricant oils in the city of Pereira, Colombia; since there is no presence of management companies engaged in the direct administration of the collection of this pollutant. To achieve this aim, six proposals of through methods of solution of two phases were discussed. First, the assignment of the group of generator points of the residue was made (previously identified). Proposals one and four of through methods are based on the closeness of points. The proposals two and five are using the scanning method and the proposals three and six are considering the restriction of the capacity of collection vehicle. Subsequently, the routes were developed - in the first three proposals by the Clarke and Wright's savings algorithm and in the following proposals by the Traveling Salesman optimization mathematical model. After applying techniques, a comparative analysis of the results was performed and it was determined which of the proposals presented the most optimal values in terms of the distance, cost and travel time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Heuristics" title="Heuristics">Heuristics</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization%20Model" title=" optimization Model"> optimization Model</a>, <a href="https://publications.waset.org/abstracts/search?q=savings%20algorithm" title=" savings algorithm"> savings algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=used%20vehicular%20oil" title=" used vehicular oil"> used vehicular oil</a>, <a href="https://publications.waset.org/abstracts/search?q=V.R.P." title=" V.R.P."> V.R.P.</a> </p> <a href="https://publications.waset.org/abstracts/56922/a-comparative-analysis-of-heuristics-applied-to-collecting-used-lubricant-oils-generated-in-the-city-of-pereira-colombia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56922.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">414</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">260</span> Identification of Novel Differentially Expressed and Co-Expressed Genes between Tumor and Adjacent Tissue in Prostate Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luis%20Enrique%20Bautista-Hinojosa">Luis Enrique Bautista-Hinojosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20A.%20Herrera"> Luis A.

In addition, the overexploitation of agricultural lands, combined with food and water scarcity, has highlighted the urgent need for sustainable cultivation methods. Hydroponics has emerged as a sustainable farming technique that enables plant cultivation using nutrient solutions without the requirement for traditional soil. Among hydroponic methods, the Nutrient Film Technique (NFT) facilitates plant growth by circulating a nutrient solution continuously. This approach allows the monitoring and precise control of nutritional parameters, with potential for automation and technological integration. This study aims to present the state of the art of automated NFT hydroponic systems, discussing their design methodologies and considerations for implementation. Moreover, a medium-scale NFT system developed at CICATA-QRO is introduced, detailing its current manual management and progress toward automation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automation" title="automation">automation</a>, <a href="https://publications.waset.org/abstracts/search?q=hydroponics" title=" hydroponics"> hydroponics</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient%20film%20technique" title=" nutrient film technique"> nutrient film technique</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/192149/development-and-automation-of-medium-scale-nft-hydroponic-systems-design-methodology-and-state-of-the-art-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192149.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">39</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">258</span> Creativity as a National System: An Exploratory Model towards Enhance Innovation Ecosystems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oscar%20Javier%20Montiel%20Mendez">Oscar Javier Montiel Mendez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The link between knowledge-creativity-innovation-entrepreneurship is well established, and broadly emphasized the importance of national innovation systems (NIS) as an approach stresses that the flow of information and technology among people, organizations and institutions are key to its process. Understanding the linkages among the actors involved in innovation is relevant to NIS. Creativity is supposed to fuel NIS, mainly focusing on a personal, group or organizational level, leaving aside the fourth one, as a national system. It is suggested that NIS takes Creativity for granted, an ex-ante stage already solved through some mechanisms, like programs for nurturing it at elementary and secondary schools, universities, or public/organizational specific programs. Or worse, that the individual already has this competence, and that the elements of the NIS will communicate between in a way that will lead to the creation of S curves, with an impact on national systems/programs on entrepreneurship, clusters, and the economy. But creativity constantly appears at any time during NIS, being the key input. Under an initial, exploratory, focused and refined literature review, based on Csikszentmihalyi’s systemic model, Amabile's componential theory, Kaufman and Beghetto’s 4C model, and the OECD’s (Organisation for Economic Co-operation and Development) NIS model (expanded), an NCS theoretical model is elaborated. Its suggested that its implementation could become a significant factor helping strengthen local, regional and national economies. The results also suggest that the establishment of a national creativity system (NCS), something that appears not been previously addressed, as a strategic/vital companion for a NIS, installing it not only as a national education strategy, but as its foundation, managing it and measuring its impact on NIS, entrepreneurship and the rest of the ecosystem, could make more effective public policies. Likewise, it should have a beneficial impact on the efforts of all the stakeholders involved and should help prevent some of the possible failures that NIS present. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=national%20creativity%20system" title="national creativity system">national creativity system</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20innovation%20system" title=" national innovation system"> national innovation system</a>, <a href="https://publications.waset.org/abstracts/search?q=entrepreneurship%20ecosystem" title=" entrepreneurship ecosystem"> entrepreneurship ecosystem</a>, <a href="https://publications.waset.org/abstracts/search?q=systemic%20creativity" title=" systemic creativity"> systemic creativity</a> </p> <a href="https://publications.waset.org/abstracts/81554/creativity-as-a-national-system-an-exploratory-model-towards-enhance-innovation-ecosystems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81554.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">430</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">257</span> Empowering Minority Students Through the use of Critical Educational Technologies: Latinos in the United States</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oscar%20Guerra">Oscar Guerra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Educational technologies have great potential as tools for student empowerment, particularly for members of a marginalized population such as immigrant Latino children in the American public education system.

Atrial remodeling might be caused as a result of paraneoplastic conditions or the result of direct expression of neoplasia. Here, we hypothesize that cancer, through inflammatory mediators, may favor the appearance of AF and patients with the first episode of AF could have a higher risk of developing cancer. Method: Data was collected from patients who attended the emergency department of our hospital for the first episode of AF, diagnosed electrocardiographically, between 2010-2015 (n = 712). The minimum follow-up was 2 years, recording the appearance of cancer, total mortality, recurrences of AF and other events. Patients who developed cancer and those who did not during the 2 years after the onset of AF were compared, as well as with the incidence of cancer in Spain in 2012. Results: After 2 years, 35 patients (4.91%) were diagnosed with cancer, with an annual incidence of 2.45%. Hematological neoplasms were the most frequent (34.28%). The cancer group was older (76.68 +/-12.75 years vs 74.16 +/-12.71; p <0.05) and had fewer typical symptoms (palpitations) (33.38% vs 14.28% , p <0.05). The incidence of cancer in Spain during 2012 was 0.46%, much lower than our sample. When comparing the incidence by age, these differences were maintained both in those over 65 years of age and in those under 65 years of age (2.17% vs. 0.28%; 0.28% vs. 0.18% respectively). Discussion: Therefore, a high incidence of cancer in patients with the first episode of AF was observed (the annual incidence of 2.45% after the onset of AF is 6.1 times that of the general population). After the evaluation of patients with AF in their first detected episode, surveillance of the appearance of cancer should be considered in clinical practice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer" title="cancer">cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiovascular%20outcomes" title=" cardiovascular outcomes"> cardiovascular outcomes</a>, <a href="https://publications.waset.org/abstracts/search?q=atrial%20fibrillation" title=" atrial fibrillation"> atrial fibrillation</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammation" title=" inflammation"> inflammation</a> </p> <a href="https://publications.waset.org/abstracts/145325/retrospective-study-on-the-prognosis-of-patients-with-new-onset-atrial-fibrillation-to-evaluate-the-risk-of-developing-occult-cancer-in-absence-of-concurrent-chronic-inflammatory-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145325.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">147</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">253</span> Hands-off Parking: Deep Learning Gesture-based System for Individuals with Mobility Needs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Javier%20Romera">Javier Romera</a>, <a href="https://publications.waset.org/abstracts/search?q=Alberto%20Justo"> Alberto Justo</a>, <a href="https://publications.waset.org/abstracts/search?q=Ignacio%20Fidalgo"> Ignacio Fidalgo</a>, <a href="https://publications.waset.org/abstracts/search?q=Joshue%20Perez"> Joshue Perez</a>, <a href="https://publications.waset.org/abstracts/search?q=Javier%20Araluce"> Javier Araluce</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, individuals with mobility needs face a significant challenge when docking vehicles. In many cases, after parking, they encounter insufficient space to exit, leading to two undesired outcomes: either avoiding parking in that spot or settling for improperly placed vehicles. To address this issue, the following paper presents a parking control system employing gestural teleoperation. The system comprises three main phases: capturing body markers, interpreting gestures, and transmitting orders to the vehicle. The initial phase is centered around the MediaPipe framework, a versatile tool optimized for real-time gesture recognition. MediaPipe excels at detecting and tracing body markers, with a special emphasis on hand gestures. Hands detection is done by generating 21 reference points for each hand. Subsequently, after data capture, the project employs the MultiPerceptron Layer (MPL) for indepth gesture classification. This tandem of MediaPipe's extraction prowess and MPL's analytical capability ensures that human gestures are translated into actionable commands with high precision. Furthermore, the system has been trained and validated within a built-in dataset. To prove the domain adaptation, a framework based on the Robot Operating System (ROS), as a communication backbone, alongside CARLA Simulator, is used. Following successful simulations, the system is transitioned to a real-world platform, marking a significant milestone in the project. This real vehicle implementation verifies the practicality and efficiency of the system beyond theoretical constructs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gesture%20detection" title="gesture detection">gesture detection</a>, <a href="https://publications.waset.org/abstracts/search?q=mediapipe" title=" mediapipe"> mediapipe</a>, <a href="https://publications.waset.org/abstracts/search?q=multiperceptron%20layer" title=" multiperceptron layer"> multiperceptron layer</a>, <a href="https://publications.waset.org/abstracts/search?q=robot%20operating%20system" title=" robot operating system"> robot operating system</a> </p> <a href="https://publications.waset.org/abstracts/174862/hands-off-parking-deep-learning-gesture-based-system-for-individuals-with-mobility-needs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174862.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">100</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">252</span> Intercultural Competencies as a Means to Rethink the Pedagogies of Diversity in Latin America</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Jose%20Cabarcas%20Ortega">Marcelo Jose Cabarcas Ortega</a>, <a href="https://publications.waset.org/abstracts/search?q=Lissette%20Herrera"> Lissette Herrera</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Carlos%20Lemus%20Stave"> Juan Carlos Lemus Stave</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work makes a rather theoretical reflection on a pedagogical response against the coloniality of knowledge and power.

The quest, nevertheless, to stimulate the interest in a non-violent, non-contemptuous education able to balance, improves and if necessary, transforms the relationships that have made it a space of privilege and exclusion. We all know the school has found itself in need of rethinking diversity while developing awareness of its own role in reproducing inequality. Intercultural education may provide an answer to that hurry when fostering critical awareness and dialogue. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decoloniality" title="decoloniality">decoloniality</a>, <a href="https://publications.waset.org/abstracts/search?q=coloniality%20of%20power" title=" coloniality of power"> coloniality of power</a>, <a href="https://publications.waset.org/abstracts/search?q=diversity" title=" diversity"> diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=interculturality" title=" interculturality"> interculturality</a> </p> <a href="https://publications.waset.org/abstracts/136227/intercultural-competencies-as-a-means-to-rethink-the-pedagogies-of-diversity-in-latin-america" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136227.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">233</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">251</span> Math Rally Proposal for the Teaching-Learning of Algebra</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liliana%20O.%20Mart%C3%ADnez">Liliana O.

The improvement of macroeconomic conditions in Latin America, starting in 2012, makes the region a new migratory destination, in both senses in north-south and south-south flows. Current studies highlight only the role of the entrepreneurial migrant in generating employment and economic growth in the region. Nevertheless, it has not been considered that not all migrants are entrepreneurs and that not all entrepreneurs contribute to economic growth. This research compares the socioeconomic and labor characteristics of migrant returnees working as freelancers in Ecuador. The principal aim is to demystify the role of migrant entrepreneurs in regional growth and to identify socioeconomic characteristics that can enhance growth. A panel econometric model was used, which is part of the information from labor and macroeconomic surveys. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=economic%20growth" title="economic growth">economic growth</a>, <a href="https://publications.waset.org/abstracts/search?q=entrepreneur" title=" entrepreneur"> entrepreneur</a>, <a href="https://publications.waset.org/abstracts/search?q=migration" title=" migration"> migration</a>, <a href="https://publications.waset.org/abstracts/search?q=returned%20migration" title=" returned migration"> returned migration</a> </p> <a href="https://publications.waset.org/abstracts/81816/the-role-of-the-returned-migration-in-the-regional-economic-growth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81816.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">212</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">248</span> Identification of Stakeholders and Practices of Inclusive Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luis%20Javier%20Serrano-Tamayo">Luis Javier Serrano-Tamayo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper focuses on the recent interest in the concept of inclusion from multiple areas of social sciences, but particularly from the academic studies on what do scholars mean when they refer to inclusive education.

Using a difference-in-difference estimation strategy and a newly-constructed database, results show that aided municipalities have significantly lower unemployment levels than non-aided municipalities. Results are significant for the decrease in unemployment for both women and people younger than 25 years old, two of the target groups of the policy. Nevertheless, they are larger for male and older workers. Therefore, findings suggest that LEADER 2017-2018 was successful in reducing unemployment in rural areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=community-led%20local%20development" title="community-led local development">community-led local development</a>, <a href="https://publications.waset.org/abstracts/search?q=ex-post%20evaluation" title=" ex-post evaluation"> ex-post evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=LEADER" title=" LEADER"> LEADER</a>, <a href="https://publications.waset.org/abstracts/search?q=rural%20development" title=" rural development"> rural development</a> </p> <a href="https://publications.waset.org/abstracts/136947/the-effect-of-leader-and-community-led-local-development-in-spanish-municipal-unemployment-a-difference-in-difference-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136947.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">341</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">243</span> Video Games Technologies Approach for Their Use in the Classroom</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Vargas-Herrera">Daniel Vargas-Herrera</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivette%20Caldelas"> Ivette Caldelas</a>, <a href="https://publications.waset.org/abstracts/search?q=Fernando%20Brambila-Paz"> Fernando Brambila-Paz</a>, <a href="https://publications.waset.org/abstracts/search?q=Rodrigo%20Montufar-Chaveznava"> Rodrigo Montufar-Chaveznava</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we present the advances corresponding to the implementation of a set of educational materials based on video games technologies.

Thus, due to its advantages comparatively with the PI controller, this paper interest is focused on the use of the sliding mode controller (SMC), Stability of the closed loop system is analytically proved using Lyapunov approach for the proposed controller. The model and the controllers are implemented in the MATLAB and SIMULINK environment. A comparison of results indicates that the suggested approach has considerable advantages compared to the traditional controller. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DC%2FDC%20boost%20converter" title="DC/DC boost converter">DC/DC boost converter</a>, <a href="https://publications.waset.org/abstracts/search?q=PEMFC" title=" PEMFC"> PEMFC</a>, <a href="https://publications.waset.org/abstracts/search?q=PI%20controller" title=" PI controller"> PI controller</a>, <a href="https://publications.waset.org/abstracts/search?q=sliding%20mode%20controller" title=" sliding mode controller"> sliding mode controller</a> </p> <a href="https://publications.waset.org/abstracts/60160/control-of-proton-exchange-membrane-fuel-cell-power-system-using-pi-and-sliding-mode-controller" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60160.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">234</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">239</span> Solar Cell Using Chemical Bath Deposited PbS:Bi3+ Films as Electron Collecting Layer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Melissa%20Chavez%20Portillo">Melissa Chavez Portillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Mauricio%20Pacio%20Castillo"> Mauricio Pacio Castillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Hector%20Juarez%20Santiesteban"> Hector Juarez Santiesteban</a>, <a href="https://publications.waset.org/abstracts/search?q=Oscar%20Portillo%20Moreno"> Oscar Portillo Moreno </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Chemical bath deposited PbS:Bi3+ as an electron collection layer is introduced between the silicon wafer and the Ag electrode the performance of the PbS heterojunction thin film solar thin film solar cells with 1 cm2 active area. We employed Bi-doping to transform it into an n-type semiconductor. The experimental results reveal that the cell response parameters depend critically on the deposition procedures in terms of bath temperature, deposition time. The device achieves an open-circuit voltage of 0.4 V. The simple and low-cost deposition method of PbS:Bi3+ films is promising for the fabrication. <p class="card-text"><strong>Keywords:</strong> <a
