Six sites inside the tropical Terminos Lagoon were sampled in order to determine abundances and ecological indexes for phytoplankton from May to December 2017. Water samples were also collected to determine the values of pigments, nutrients, and water solids. Results showed that the composition and abundance of the phytoplankton community were influenced by physicochemical factors, nutrients, water solids, and climate seasons. Sixty-six species were identified as potential HAB producers (44.29% from total). However, abundances were not related to the occurrence of HAB during the study. Multidimensional ANOVA indicated no significant differences between sites while some months revealed significant differences. The canonical analysis suggested that environmental variables explained 49% of community variation of potential phytoplankton species producers of HAB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phytoplankton" title="phytoplankton">phytoplankton</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=lagoon" title=" lagoon"> lagoon</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title=" biodiversity"> biodiversity</a> </p> <a href="https://publications.waset.org/abstracts/122868/phytoplankton-community-composition-in-laguna-de-terminos-mexico-and-its-relationship-to-environmental-variables" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122868.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">139</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">75</span> Development of a Tesla Music Coil from Signal Processing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samaniego%20Campoverde%20Jos%C3%A9%20Enrique">Samaniego Campoverde José Enrique</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosero%20Mu%C3%B1oz%20Jorge%20Enrique"> Rosero Muñoz Jorge Enrique</a>, <a href="https://publications.waset.org/abstracts/search?q=Luzcando%20Narea%20Lorena%20Elizabeth"> Luzcando Narea Lorena Elizabeth</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a practical and theoretical model for the operation of the Tesla coil using digital signal processing.

However, the topic of data literacy has only marginally touched the early care and education (ECE) field. In California, within the ECE workforce, there is a group of professionals working in policy and advocacy that use quantitative data regularly and whose educational and professional experiences have been neglected by existing research. This study aimed at analyzing these experiences in accessing, using, and producing quantitative data. This study utilized semi-structured interviews to capture the differences in educational and professional backgrounds, policy contexts, and power relations. The participants were three key professionals from county-level organizations and one working at a State Department to allow for a broader perspective at systems level. The study followed Núñez’s multilevel model of intersectionality. The key in Núñez’s model is the intersection of multiple levels of analysis and influence, from the individual to the system level, and the identification of institutional power dynamics that perpetuate the marginalization of certain groups within society. In a similar manner, this study looked at the dynamic interaction of different influences at individual, organizational, and system levels that might intersect and affect ECE professionals’ experiences with quantitative data. At the individual level, an important element identified was the participants’ educational background, as it was possible to observe a relationship between that and their positionality, both with respect to working with data and also with respect to their power within an organization and at the policy table. For example, those with a background in child development were aware of how their formal education failed to train them in the skills that are necessary to work in policy and advocacy, and especially to work with quantitative data, compared to those with a background in administration and/or business. At the organizational level, the interviews showed a connection between the participants’ position within the organization and their organization’s position with respect to others and their degree of access to quantitative data. This in turn affected their sense of empowerment and agency in dealing with data, such as shaping what data is collected and available. These differences reflected on the interviewees’ perceptions and expectations for the ECE workforce. For example, one of the interviewees pointed out that many ECE professionals happen to use data out of the necessity of the moment. This lack of intentionality is a cause for, and at the same time translates into missed training opportunities. Another interviewee pointed out issues related to the professionalism of the ECE workforce by remarking the inadequacy of ECE students’ training in working with data. In conclusion, Núñez’s model helped understand the different elements that affect ECE professionals’ experiences with quantitative data. In particular, what was clear is that these professionals are not being provided with the necessary support and that we are not being intentional in creating data literacy skills for them, despite what is asked of them and their work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data%20literacy" title="data literacy">data literacy</a>, <a href="https://publications.waset.org/abstracts/search?q=early%20childhood%20professionals" title=" early childhood professionals"> early childhood professionals</a>, <a href="https://publications.waset.org/abstracts/search?q=intersectionality" title=" intersectionality"> intersectionality</a>, <a href="https://publications.waset.org/abstracts/search?q=quantitative%20data" title=" quantitative data"> quantitative data</a> </p> <a href="https://publications.waset.org/abstracts/54181/a-qualitative-study-identifying-the-complexities-of-early-childhood-professionals-use-and-production-of-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54181.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">253</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">72</span> Modelling of Damage as Hinges in Segmented Tunnels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gelacio%20Ju%C3%A1Rez-Luna">Gelacio JuáRez-Luna</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Enrique%20Gonz%C3%A1Lez-Ram%C3%ADRez"> Daniel Enrique GonzáLez-RamíRez</a>, <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Tenorio-Montero"> Enrique Tenorio-Montero</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Frame elements coupled with springs elements are used for modelling the development of hinges in segmented tunnels, the spring elements modelled the rotational, transversal and axial failure. These spring elements are equipped with constitutive models to include independently the moment, shear force and axial force, respectively. These constitutive models are formulated based on damage mechanics and experimental test reported in the literature review. The mesh of the segmented tunnels was discretized in the software GID, and the nonlinear analyses were carried out in the finite element software ANSYS. These analyses provide the capacity curve of the primary and secondary lining of a segmented tunnel. Two numerical examples of segmented tunnels show the capability of the spring elements to release energy by the development of hinges. The first example is a segmental concrete lining discretized with frame elements loaded until hinges occurred in the lining. The second example is a tunnel with primary and secondary lining, discretized with a double ring frame model. The outer ring simulates the segmental concrete lining and the inner ring simulates the secondary cast-in-place concrete lining. Spring elements also modelled the joints between the segments in the circumferential direction and the ring joints, which connect parallel adjacent rings. The computed load vs displacement curves are congruent with numerical and experimental results reported in the literature review. It is shown that the modelling of a tunnel with primary and secondary lining with frame elements and springs provides reasonable results and save computational cost, comparing with 2D or 3D models equipped with smeared crack models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damage" title="damage">damage</a>, <a href="https://publications.waset.org/abstracts/search?q=hinges" title=" hinges"> hinges</a>, <a href="https://publications.waset.org/abstracts/search?q=lining" title=" lining"> lining</a>, <a href="https://publications.waset.org/abstracts/search?q=tunnel" title=" tunnel"> tunnel</a> </p> <a href="https://publications.waset.org/abstracts/56714/modelling-of-damage-as-hinges-in-segmented-tunnels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56714.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">390</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">71</span> Design of a 4-DOF Robot Manipulator with Optimized Algorithm for Inverse Kinematics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20G%C3%B3mez">S.

Nowadays, psychoanalytic theory is applied to numerous fields. One of them is literature. Literary criticism has put into practice the basis of Freud’s idea to analyze literary works. This essay is about the analysis of Edgar A. Poe’s short story ‘The Tell-Tale Heart,’ under the lens of Freud’s psychoanalytical perspective. In 1919, it was published ‘Das Unheimliche’ (The Uncanny) by Freud. On this article, the famous Austrian psychoanalyst showed his explanations about what he called ‘the uncanny,’ and its relation to the human unconscious. In this paper, Freud’s famous article has been used to analyze Poe’s short story ‘The Tell-Tale Heart,’ and to find the analogies that exist between Poe’s macabre short story and Freud’s theory of ‘the uncanny.’ <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=psychoanalysis" title="psychoanalysis">psychoanalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=theory%20of%20the%20unconscious" title=" theory of the unconscious"> theory of the unconscious</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20uncanny" title=" the uncanny"> the uncanny</a>, <a href="https://publications.waset.org/abstracts/search?q=unheimlich" title=" unheimlich"> unheimlich</a> </p> <a href="https://publications.waset.org/abstracts/71692/a-psychoanalytical-approach-to-edgar-a-poes-short-story-the-tell-tale-heart" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71692.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">645</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">64</span> Mechanic and Thermal Analysis on an 83 kW Electric Motorcycle: A First-Principles Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mart%C3%ADn%20Felipe%20Garc%C3%ADa%20Romero">Martín Felipe García Romero</a>, <a href="https://publications.waset.org/abstracts/search?q=Nancy%20Mondrag%C3%B3n%20Escamilla"> Nancy Mondragón Escamilla</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismael%20Araujo%20Vargas"> Ismael Araujo Vargas</a>, <a href="https://publications.waset.org/abstracts/search?q=Viviana%20Basurto%20Rios"> Viviana Basurto Rios</a>, <a href="https://publications.waset.org/abstracts/search?q=Kevin%20Cano%20Pulido"> Kevin Cano Pulido</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Enrique%20Vel%C3%A1zquez%20Elisondo"> Pedro Enrique Velázquez Elisondo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a preliminary prototype of an 83 kW all-electric motorbike since, nowadays, electric motorbikes have advanced drastically in their technology in such a way that lately, there has been a boom in the field of competition of medium power electric vehicles.

To compare these techniques we use a cost functional that minimize the wild-type virus population and the mutant virus population, but the main objective is to minimize the systemic cost of treatment and maximize levels of healthy CD4+ T cells. HyOOC, HOOC, and sSTI are applied to the drug therapies using a reverse transcriptase and protease inhibitors; simulations show that these controls maintain the uninfected cells in a small, bounded neighborhood of a pre-specified level.

The diagnosis is related to the interpretation of the data, findings and the relevant information, to determine problems, causes, or the simple state and behavior of a process, without including a solution to the problems detected. The objective of this work is to identify the necessary stages to diagnose the logistic processes in a metalworking company, from the literary revision of different disciplines. A total of 62 articles were chosen to identify, through bibliometric analysis, the most cited articles, as well as the most frequent authors and journals. The results allowed to identify the two fundamental stages in the diagnostic process: a primary phase (general) based on the logical subjectivity of the knowledge of the person who evaluates, and the secondary phase (specific), related to the interpretation of the results, findings or data. Also, two phases were identified, one related to the definition of the scope of the actions to be developed and the other, as an initial description of what was observed in the process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=business" title="business">business</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnostic" title=" diagnostic"> diagnostic</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a>, <a href="https://publications.waset.org/abstracts/search?q=process" title=" process"> process</a> </p> <a href="https://publications.waset.org/abstracts/99714/diagnosis-of-logistics-processes-bibliometric-review-and-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99714.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">157</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">59</span> Scale Prototype to Estimate the Resistance to Lateral Displacement Buried Pipes and submerged in non-Cohesive Soils </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Casta%C3%B1eda">Enrique Castañeda</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomas%20Hernadez"> Tomas Hernadez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mario%20Ulloa"> Mario Ulloa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recent studies related to submarine pipelines under high pressure, temperature and buried, forces us to make bibliographical and documentary research to make us of references applicable to our problem.

Although usually referred to as ”lotteries”, there is evidence that some national teams and clubs consistently perform better than others. The outcomes are therefore not explained just by mere luck, and therefore there are ways to improve the average performance of players, naturally at the expense of some sort of effort. In this article we study the payoff of player performance improvements in terms of the performance of the team as a whole. To do so we develop an analytical model with static individual performances, as well as Monte Carlo models that take into account the known influence of partial score and round number on individual performances. We find that within a range of usual values, the team performance improves above 70% faster than individual performances do. Using these models, we also estimate that the new ABBA penalty shootout ordering under test reduces almost all the known bias in favor of the first-shooting team under the current ABAB system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=football" title="football">football</a>, <a href="https://publications.waset.org/abstracts/search?q=penalty%20shootouts" title=" penalty shootouts"> penalty shootouts</a>, <a href="https://publications.waset.org/abstracts/search?q=Montecarlo%20simulation" title=" Montecarlo simulation"> Montecarlo simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=ABBA" title=" ABBA"> ABBA</a> </p> <a href="https://publications.waset.org/abstracts/104452/modeling-football-penalty-shootouts-how-improving-individual-performance-affects-team-performance-and-the-fairness-of-the-abab-sequence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104452.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">162</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">57</span> Comparison of Two Fuzzy Skyhook Control Strategies Applied to an Active Suspension</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reginaldo%20Cardoso">Reginaldo Cardoso</a>, <a href="https://publications.waset.org/abstracts/search?q=Magno%20Enrique%20Mendoza%20Meza"> Magno Enrique Mendoza Meza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work focuses on simulation and comparison of two control skyhook techniques applied to a quarter-car of the active suspension. The objective is to provide comfort to the driver. The main idea of skyhook control is to imagine a damper connected to an imaginary sky; thus, the feedback is performed with the resultant force between the imaginary and the suspension damper. The first control technique is the Mandani fuzzy skyhook and the second control technique is a Takagi-Sugeno fuzzy skyhook controller, in the both controllers the inputs are the relative velocity between the two masses and the vehicle body velocity, the output of the Mandani fuzzy skyhook is the coefficient of imaginary damper viscous-friction and the Takagi-Sugeno fuzzy skyhook is the force. Finally, we compared the techniques. The Mandani fuzzy skyhook showed a more comfortable response to the driver, followed closely by the Takagi- Sugeno fuzzy skyhook. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20suspention" title="active suspention">active suspention</a>, <a href="https://publications.waset.org/abstracts/search?q=Mandani" title=" Mandani"> Mandani</a>, <a href="https://publications.waset.org/abstracts/search?q=quarter-car" title=" quarter-car"> quarter-car</a>, <a href="https://publications.waset.org/abstracts/search?q=skyhook" title=" skyhook"> skyhook</a>, <a href="https://publications.waset.org/abstracts/search?q=Sugeno" title=" Sugeno"> Sugeno</a> </p> <a href="https://publications.waset.org/abstracts/32492/comparison-of-two-fuzzy-skyhook-control-strategies-applied-to-an-active-suspension" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32492.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">464</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">56</span> Application of Sensory Thermography on Workers of a Wireless Industry in Mexico</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Claudia%20Camargo%20Wilson">Claudia Camargo Wilson</a>, <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Javier%20de%20la%20Vega%20Bustillos"> Enrique Javier de la Vega Bustillos</a>, <a href="https://publications.waset.org/abstracts/search?q=Jes%C3%BAs%20Everardo%20Olgu%C3%ADn%20Tiznado"> Jesús Everardo Olguín Tiznado</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Andr%C3%A9s%20L%C3%B3pez%20Barreras"> Juan Andrés López Barreras</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20K.%20Enriquez"> Sandra K.

We consider important to determine the reasons that are producing early death in this specific type of population, since they are the most vulnerable to high risk environmental conditions. In this way, the government, through competent authorities, may develop prevention policies and the right measures to avoid an increase of this tragic fact. The methodology used to develop this investigation is data mining, which consists in gaining and examining large amounts of data to produce new and valuable information. Through this technique it has been possible to determine that the child population is dying mostly from malnutrition. In short, this technique has been very useful to develop this study; it has allowed us to transform large amounts of information into a conclusive and important statement, which has made it easier to take appropriate steps to resolve a particular situation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=malnutrition" title="malnutrition">malnutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20mining" title=" data mining"> data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical" title=" analytical"> analytical</a>, <a href="https://publications.waset.org/abstracts/search?q=descriptive" title=" descriptive"> descriptive</a>, <a href="https://publications.waset.org/abstracts/search?q=population" title=" population"> population</a>, <a href="https://publications.waset.org/abstracts/search?q=Wayuu" title=" Wayuu"> Wayuu</a>, <a href="https://publications.waset.org/abstracts/search?q=indigenous" title=" indigenous"> indigenous</a> </p> <a href="https://publications.waset.org/abstracts/86076/main-cause-of-childrens-deaths-in-indigenous-wayuu-community-from-department-of-la-guajira-a-research-developed-through-data-mining-use" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86076.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">159</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">54</span> Soil-Structure Interaction in Stiffness and Strength Degrading Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Bazan-Zurita">Enrique Bazan-Zurita</a>, <a href="https://publications.waset.org/abstracts/search?q=Sittipong%20Jarernprasert"> Sittipong Jarernprasert</a>, <a href="https://publications.waset.org/abstracts/search?q=Jacobo%20Bielak"> Jacobo Bielak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We study the effects of soil-structure interaction (SSI) on the inelastic seismic response of a single-degree-of-freedom system whose hysteretic behaviour exhibits stiffness and/or strength degrading characteristics. Two sets of accelerograms are used as seismic input: the first comprising 87 record from stiff to medium stiff sites in California, and the second comprising 66 records from the soft lakebed of Mexico City. This study focuses in three seismic response parameters: ductility demand, inter-story drift, and total lateral displacement. The results allow quantitative estimates of changes in such parameters in an SSI system in comparison with those corresponding to the associated fixed-base system. We found that degrading features affect significantly both the response of fixed-base structures and the impact of soil-structure interaction. We propose a procedure to incorporate the results of this and similar studies in seismic design regulations for SSI system with anticipated nonlinear degrading behaviour. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inelastic" title="inelastic">inelastic</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic" title=" seismic"> seismic</a>, <a href="https://publications.waset.org/abstracts/search?q=building" title=" building"> building</a>, <a href="https://publications.waset.org/abstracts/search?q=foundation" title=" foundation"> foundation</a>, <a href="https://publications.waset.org/abstracts/search?q=interaction" title=" interaction"> interaction</a> </p> <a href="https://publications.waset.org/abstracts/7045/soil-structure-interaction-in-stiffness-and-strength-degrading-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7045.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">286</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">53</span> Application of Lean Manufacturing Tools in Hot Asphalt Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Bayona">S.

This article analyzes the production process of a hot asphalt manufacturing company from an administrative and technical perspective. Three main phases were analyzed, the first phase was related to the determination of the risk priority number of the main operations in asphalt mix production process by an FMEA (Failure Mode Effects Analysis), in the second phase the Value Stream Mapping (VSM) of the production line was performed and in the third phase a SWOT (Strengths, Weaknesses Opportunities, Threats) matrix was constructed. Among the most valued failure modes were the lack training of workers in occupational safety and health issues, the lack of signaling and classification of granulated material, and the overweight of vehicles loaded. The analysis of the results in the three phases agree on the importance of training operational workers, improve communication with external actors in order to minimize delays in material orders and strengthen control suppliers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asphalt" title="asphalt">asphalt</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20manufacturing" title=" lean manufacturing"> lean manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=productivity" title=" productivity"> productivity</a>, <a href="https://publications.waset.org/abstracts/search?q=process" title=" process"> process</a> </p> <a href="https://publications.waset.org/abstracts/99710/application-of-lean-manufacturing-tools-in-hot-asphalt-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99710.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">116</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">52</span> D6tions: A Serious Game to Learn Software Engineering Process and Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hector%20G.%20Perez-Gonzalez">Hector G.

To improve this process, researchers have proposed merely illustrative techniques in the classroom, such as topic presentations and dynamics between students on one side or attempts to involve students in real projects with companies and institutions to bring them to a real software development problem on the other hand. Simulators and serious games have been used as auxiliary tools to introduce students to topics that are too abstract when these are presented in the traditional way. Most of these tools cover a limited area of the huge software engineering scope. To address this problem, we have developed D6tions, an educational serious game that simulates the software engineering process and is designed to experiment the different stages a software engineer (playing roles as project leader or as a developer or designer) goes through, while participating in a software project. We describe previous approaches to this problem, how D6tions was designed, its rules, directions, and the results we obtained of the use of this game involving undergraduate students playing the game. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=serious%20games" title="serious games">serious games</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20engineering" title=" software engineering"> software engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20engineering%20education" title=" software engineering education"> software engineering education</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20engineering%20teaching%20process" title=" software engineering teaching process"> software engineering teaching process</a> </p> <a href="https://publications.waset.org/abstracts/37912/d6tions-a-serious-game-to-learn-software-engineering-process-and-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37912.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">493</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">51</span> The Filipino Catholics in Japan: Traces and Cues of De/Ghettoization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Willard%20Enrique%20R.%20Macaraan">Willard Enrique R.

This paper aims to uncover the nuances of this marginality by utilizing Loic Wacquant's theorization of urban ghettos as well as Pierre Bourdieu's field ideation. In an attempt to illustrate the dynamics of the power-play that is implicit in any situation of marginality, the paper proposes a 'diamond-quadrant' (DQ) plane that may serve as a heuristic device for analytical purposes. This study is drawn from data collected and gathered through ten-month field research in selected church communities in the Archdiocese of Tokyo, Japan employing qualitative methodologies like participant observation, interviews, and document reviews. Reconstructing their historicized struggle since the late 70s, it is discovered that the arena of contested space has shifted from the right plane of "ghettoization" tendencies in the early years towards the left plane of "deghettoization" strategies in recent years. Still, a highly negotiated space, several situational factors, and emerging trends in and outside the ecclesial grounds have led to this major shift. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wacquant" title="Wacquant">Wacquant</a>, <a href="https://publications.waset.org/abstracts/search?q=ghetto" title=" ghetto"> ghetto</a>, <a href="https://publications.waset.org/abstracts/search?q=migration" title=" migration"> migration</a>, <a href="https://publications.waset.org/abstracts/search?q=religion" title=" religion"> religion</a> </p> <a href="https://publications.waset.org/abstracts/151055/the-filipino-catholics-in-japan-traces-and-cues-of-deghettoization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151055.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">93</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">50</span> Math Anxiety Effects on Complex Addition: An ERP Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Isabel%20N%C3%BA%C3%B1ez-Pe%C3%B1a">María Isabel Núñez-Peña</a>, <a href="https://publications.waset.org/abstracts/search?q=Macarena%20Su%C3%A1rez%20Pellicioni"> Macarena Suárez Pellicioni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present study, we used event-related potentials (ERP) to address the question of whether high (HMA) and low math-anxious (LMA) individuals differ on a complex addition verification task, which involved both carrying and non-carrying additions. ERPs were recorded while seventeen HMA and seventeen LMA individuals performed the verification task. Groups did not differ in trait anxiety or gender distribution. Participants were presented with two-digit additions and were asked to decide whether the proposed solution was correct or incorrect. Behavioral data showed a significant Carrying x Proposed solution x Group interaction for accuracy, showing that carrying additions were more error prone than non-carrying ones for both groups, although the difference non-carrying minus carrying was larger for the HMA group. As for ERPs, a P2 component larger in HMA individuals than in their LMA peers was found both for carrying and non-carrying additions. The P2 was followed by a sustained negative slow wave at parietal positions. Because the negative slow waves are thought to reflect the updating of working memory, these results give support to the relationship among working memory, math performance and math anxiety. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=math%20anxiety" title="math anxiety">math anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=carrying" title=" carrying"> carrying</a>, <a href="https://publications.waset.org/abstracts/search?q=working%20memory" title=" working memory"> working memory</a>, <a href="https://publications.waset.org/abstracts/search?q=P2" title=" P2 "> P2 </a> </p> <a href="https://publications.waset.org/abstracts/25642/math-anxiety-effects-on-complex-addition-an-erp-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25642.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">447</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">49</span> Aquatic and Marshy Flora from Fresh Water Wetlands on Quartz Sands in Pinar Del Río, Cuba</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vidal%20P%C3%A9rez%20Hern%C3%A1ndez">Vidal Pérez Hernández</a>, <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Gonz%C3%A1lez%20Pend%C3%A1s"> Enrique González Pendás</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The most of the aquatic and marshy flora in Cuba, is located on quartzitic sands ecosystems and they are represented by a wide variety of freshwater wetlands, which are spread in the whole south and south-western plain of Pinar del Río. The survey carried out in these ecosystems offers an updated inventory of these species, showing up their biological type, habit, distribution, and the threat grade to which are subjected, taking into account categories granted by UICN. A remarkable decrease is evidenced, in the total of these species respect to this area; due to deposit processes and deforestation, which are taken place by the human activity and the climatic change. It is linked to others threats like, limitless use of their water reserves for irrigating groves, the cattle raising and intensive fishing. Added to it, its sand with 99% pure crystal quartz, are used for the mining. The combination of all factors has a negative influence on a flora that stores more than 250 species, most of them herbaceous and hydrophytes.

Monitoring is essential for environmental, aquaculture, and agricultural disciplines, where this type of instrumentation is necessary for data collection. The system uses low-cost components, which allows readings close to those with high-cost probes. The probe collects readings such as the coordinates of the geographical position, as well as the time it records the target parameters of the monitored. The modules or subsystems that make up the probe are the global positioning (GPS), which shows the altitude, latitude, and longitude data of the point where the reading will be recorded, a real-time clock stage, the date marking the time, the module SD memory continuously stores data, data acquisition system, central processing unit, and energy. The system acquires parameters to measure water quality, conductivity, pressure, and temperature, and for air, three types of ammonia, dioxide, and carbon monoxide gases were censored. The information obtained allowed us to identify the schedule of modification of the parameters and the identification of the ideal conditions for the growth of microorganisms in the water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calibration" title="calibration">calibration</a>, <a href="https://publications.waset.org/abstracts/search?q=conductivity" title=" conductivity"> conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=datalogger" title=" datalogger"> datalogger</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring" title=" monitoring"> monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20time%20clock" title=" real time clock"> real time clock</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/145653/modular-probe-for-basic-monitoring-of-water-and-air-quality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145653.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">47</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. As future work, the lecturer can do personalized teaching, because knows the behavior of all students in each formative assessment <p class="card-text"><strong>Keywords:</strong> <a
