Hence, with the privatization of the sector, all the companies are racing for a more efficient and reliant way to set satellites in orbit. Having detected the current needs for power management in the launcher vehicle industry, the Modular Power Bus is proposed as a technology to revolutionize power management in current and future Launcher Vehicles. The MPBus Project is committed to develop a new power bus architecture combining ejectable batteries with the main bus through intelligent nodes. These nodes are able to communicate between them and a battery controller using an improved, data over DC line technology, expected to reduce the total weight in two main areas: improving the use of the batteries and reducing the total weight due to harness. This would result in less weight for each launch stage increasing the operational satellite payload and reducing cost. These features make the system suitable for a number of launchers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=modular%20power%20bus" title="modular power bus">modular power bus</a>, <a href="https://publications.waset.org/abstracts/search?q=Launcher%20vehicles" title=" Launcher vehicles"> Launcher vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=ejectable%20batteries" title=" ejectable batteries"> ejectable batteries</a>, <a href="https://publications.waset.org/abstracts/search?q=intelligent%20nodes" title=" intelligent nodes"> intelligent nodes</a> </p> <a href="https://publications.waset.org/abstracts/21253/modular-power-bus-for-space-vehicles-mpbus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21253.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">480</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">211</span> Continuous Improvement in Emerging Economies: Insights from a Multi-Case Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luis%20A.%20Paipa-Galeano">Luis A.

The study analyzes the empirical evidence and compares it to the literature review to provide insights for companies looking to increase their maturity level in this area. The five success factors identified are the availability of resources, commitment and support from management, participation of employees in identifying tasks to improve, clear and realistic objectives for continuous improvement, and the existence of a leader or responsible for continuous improvement. The major barriers to success are a lack of alignment between the organization’s strategic objectives and continuous improvement objectives, a lack of motivation in the team, and resistance to change. The paper concludes with recommendations for companies to reduce the risk of improvement failure and increase their maturity level in continuous improvement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emerging%20economies" title="emerging economies">emerging economies</a>, <a href="https://publications.waset.org/abstracts/search?q=Kaizen" title=" Kaizen"> Kaizen</a>, <a href="https://publications.waset.org/abstracts/search?q=continuous%20improvement%20sustainability" title=" continuous improvement sustainability"> continuous improvement sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=maturity%20model" title=" maturity model"> maturity model</a> </p> <a href="https://publications.waset.org/abstracts/181887/continuous-improvement-in-emerging-economies-insights-from-a-multi-case-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181887.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">73</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">210</span> Environmental Education and Water Resources Management in the City of Belem, Para, Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naiara%20de%20Almeida%20Rios">Naiara de Almeida Rios</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The environmental education, from Tbilisi, is signaled as an important instrument for conservation and environmental management. However, the social, economic, political and environmental aspects of each place require an environmental management that corresponds to the reality to which they are inserted, as well as environmental education practices. The city of Belém, the capital of the State of Pará, is one of the most important cities in the Amazon Region, and its vast water dimension requires that its watersheds take a careful look at their socio-environmental management. The Estrada Nova Hydrographic Basin is considered as one of the most critical river basins in the city due to flooding, lack of basic sanitation and degradation of water bodies. In this context, environmental education is understood as one of the necessary conditions to reduce environmental degradation. Environmental education presents itself as an instrument of social transformation and conservation of natural resources (especially water resources), where thinking about the sustainability of natural resources is moving towards dialogue on the importance of building an environmental awareness. The commitment that environmental education proposes covers all spheres of society, since the main objective of the same is the transformation of thought and attitudes from the understanding of reality. Therefore, to analyze how the government is managing the basin, as well as the environmental education practices developed in it, is fundamental, so that government can be charged with improvements for the population and for the natural environment. Therefore, the objective of this study is to analyze the influence of environmental education actions developed by local public authorities in the management of the Estrada Nova Hydrographic Basin, Belém/PA. For the accomplishment of this study, some methodological procedures will be used, like documentary analysis, bibliographical survey and fieldwork. If the multivariate statistical method is used to analyze the results obtained in the field. Unfortunately, public policies in the area of environmental education in Belém are still moving in short steps, since government interests have had very little dialogue with the socio-environmental problems that affect the Estrada Nova Hydrographic Basin. Both formal and informal environmental education has been poorly developed, hampering the continuous process proposed by water resources management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20education" title="environmental education">environmental education</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20management" title=" environmental management"> environmental management</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrographic%20basin" title=" hydrographic basin"> hydrographic basin</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20resources" title=" water resources"> water resources</a> </p> <a href="https://publications.waset.org/abstracts/85320/environmental-education-and-water-resources-management-in-the-city-of-belem-para-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85320.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">189</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">209</span> Implementation in Python of a Method to Transform One-Dimensional Signals in Graphs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luis%20Andrey%20Fajardo%20Fajardo">Luis Andrey Fajardo Fajardo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We are immersed in complex systems. The human brain, the galaxies, the snowflakes are examples of complex systems. An area of interest in Complex systems is the chaos theory. This revolutionary field of science presents different ways of study than determinism and reductionism. Here is where in junction with the Nonlinear DSP, chaos theory offer valuable techniques that establish a link between time series and complex theory in terms of complex networks, so that, the study of signals can be explored from the graph theory. Recently, some people had purposed a method to transform time series in graphs, but no one had developed a suitable implementation in Python with signals extracted from Chaotic Systems or Complex systems. That’s why the implementation in Python of an existing method to transform one dimensional chaotic signals from time domain to graph domain and some measures that may reveal information not extracted in the time domain is proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Python" title="Python">Python</a>, <a href="https://publications.waset.org/abstracts/search?q=complex%20systems" title=" complex systems"> complex systems</a>, <a href="https://publications.waset.org/abstracts/search?q=graph%20theory" title=" graph theory"> graph theory</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamical%20systems" title=" dynamical systems"> dynamical systems</a> </p> <a href="https://publications.waset.org/abstracts/25768/implementation-in-python-of-a-method-to-transform-one-dimensional-signals-in-graphs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25768.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">509</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">208</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">207</span> Benchmarking of Pentesting Tools</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Esteban%20Alejandro%20Armas%20Vega">Esteban Alejandro Armas Vega</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Lucila%20Sandoval%20Orozco"> Ana Lucila Sandoval Orozco</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Javier%20Garc%C3%ADa%20Villalba"> Luis Javier García Villalba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The benchmarking of tools for dynamic analysis of vulnerabilities in web applications is something that is done periodically, because these tools from time to time update their knowledge base and search algorithms, in order to improve their accuracy. Unfortunately, the vast majority of these evaluations are made by software enthusiasts who publish their results on blogs or on non-academic websites and always with the same evaluation methodology. Similarly, academics who have carried out this type of analysis from a scientific approach, the majority, make their analysis within the same methodology as well the empirical authors. This paper is based on the interest of finding answers to questions that many users of this type of tools have been asking over the years, such as, to know if the tool truly test and evaluate every vulnerability that it ensures do, or if the tool, really, deliver a real report of all the vulnerabilities tested and exploited. This kind of questions have also motivated previous work but without real answers. The aim of this paper is to show results that truly answer, at least on the tested tools, all those unanswered questions. All the results have been obtained by changing the common model of benchmarking used for all those previous works. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cybersecurity" title="cybersecurity">cybersecurity</a>, <a href="https://publications.waset.org/abstracts/search?q=IDS" title=" IDS"> IDS</a>, <a href="https://publications.waset.org/abstracts/search?q=security" title=" security"> security</a>, <a href="https://publications.waset.org/abstracts/search?q=web%20scanners" title=" web scanners"> web scanners</a>, <a href="https://publications.waset.org/abstracts/search?q=web%20vulnerabilities" title=" web vulnerabilities"> web vulnerabilities</a> </p> <a href="https://publications.waset.org/abstracts/70338/benchmarking-of-pentesting-tools" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70338.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">319</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">206</span> Progress in Accuracy, Reliability and Safety in Firedamp Detection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Luis%20Lorenzo%20Bayona">José Luis Lorenzo Bayona</a>, <a href="https://publications.waset.org/abstracts/search?q=Ljiljana%20Medic-Pejic"> Ljiljana Medic-Pejic</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabel%20Amez%20Arenillas"> Isabel Amez Arenillas</a>, <a href="https://publications.waset.org/abstracts/search?q=Blanca%20Castells%20Somoza"> Blanca Castells Somoza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The communication presents the study results carried out by the Official Laboratory J.

Poor firedamp control in work can cause from production stoppages to fatal accidents and since there is currently a great variety of equipment with different functional characteristics, a study is needed to indicate which measurement principles have the highest degree of confidence. For the development of the project, a series of fixed, transportable and portable methane detectors with different measurement principles have been selected to subject them to laboratory tests following the methods described in the applicable regulations. The test equipment has been the one usually used in the certification and calibration of these devices, subject to the LOM quality system, and the tests have been carried out on detectors accessible in the market. The conclusions establish the main advantages and disadvantages of the equipment according to the measurement principle used; catalytic combustion, interferometry and infrared absorption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ATEX%20standards" title="ATEX standards">ATEX standards</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20detector" title=" gas detector"> gas detector</a>, <a href="https://publications.waset.org/abstracts/search?q=methane%20meter" title=" methane meter"> methane meter</a>, <a href="https://publications.waset.org/abstracts/search?q=mining%20safety" title=" mining safety"> mining safety</a> </p> <a href="https://publications.waset.org/abstracts/137583/progress-in-accuracy-reliability-and-safety-in-firedamp-detection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137583.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">137</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">205</span> The Public Law Studies: Relationship Between Accountability, Environmental Education and Smart Cities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aline%20Alves%20Bandeira">Aline Alves Bandeira</a>, <a href="https://publications.waset.org/abstracts/search?q=Lu%C3%ADs%20Pedro%20Lima"> Luís Pedro Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Cec%C3%ADlia%20de%20Paula%20Silva"> Maria Cecília de Paula Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulo%20Henrique%20de%20Viveiros%20Tavares"> Paulo Henrique de Viveiros Tavares</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, the study of public policies regarding management efficiency is essential. Public policies are about what governments do or do not do, being an area that has grown worldwide, contributing through the knowledge of technologies and methodologies that monitor and evaluate the performance of public administrators. The information published on official government websites needs to provide for transparency and responsiveness of managers. Thus, transparency is a primordial factor for the execution of Accountability, providing, in this way, services to the citizen with the expansion of transparent, efficient, democratic information and that value administrative eco-efficiency. The ecologically balanced management of a Smart City must optimize environmental education, building a fairer society, which brings about equality in the use of quality environmental resources. Smart Cities add value in the construction of public management, enabling interaction between people, enhancing environmental education and the practical applicability of administrative eco-efficiency, fostering economic development and improving the quality of life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accountability" title="accountability">accountability</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20education" title=" environmental education"> environmental education</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20public%20administration" title=" new public administration"> new public administration</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20cities" title=" smart cities"> smart cities</a> </p> <a href="https://publications.waset.org/abstracts/140750/the-public-law-studies-relationship-between-accountability-environmental-education-and-smart-cities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140750.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">128</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">204</span> Digital Maturity Framework: A Tool to Manage the Information Technologies and Develop Activities of Innovation in Companies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paulina%20Sol%C3%B3rzano%20Salgado">Paulina Solórzano Salgado</a>, <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=Alberto%20de%20Jes%C3%BAs%20Pastrana%20Palma"> Alberto de Jesús Pastrana Palma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this research, it is presented a digital maturity framework, which contributes to the development of small and medium-sized enterprises (SMEs) in the commercial sector.

The instrument was applied to 64 Mexican companies from the Made in Mexico database, which allowed both descriptive results and correlation results. These contributed to the development of the methodology, and confirming that the management of digital marketing has a positive relation with innovation activities of companies. Also, that analytics in digital marketing is a source for its development. In this paper, the management stages and activities are presented to be developed by companies in order to generate knowledge, which will allow them to reach its digital maturity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20marketing" title="digital marketing">digital marketing</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20maturity" title=" digital maturity"> digital maturity</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation" title=" innovation"> innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=SMEs" title=" SMEs"> SMEs</a> </p> <a href="https://publications.waset.org/abstracts/70476/digital-maturity-framework-a-tool-to-manage-the-information-technologies-and-develop-activities-of-innovation-in-companies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70476.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">469</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">203</span> Influence of the Refractory Period on Neural Networks Based on the Recognition of Neural Signatures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Luis%20Carrillo-Medina">José Luis Carrillo-Medina</a>, <a href="https://publications.waset.org/abstracts/search?q=Roberto%20Latorre"> Roberto Latorre</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Experimental evidence has revealed that different living neural systems can sign their output signals with some specific neural signature. Although experimental and modeling results suggest that neural signatures can have an important role in the activity of neural networks in order to identify the source of the information or to contextualize a message, the functional meaning of these neural fingerprints is still unclear. The existence of cellular mechanisms to identify the origin of individual neural signals can be a powerful information processing strategy for the nervous system. We have recently built different models to study the ability of a neural network to process information based on the emission and recognition of specific neural fingerprints. In this paper we further analyze the features that can influence on the information processing ability of this kind of networks. In particular, we focus on the role that the duration of a refractory period in each neuron after emitting a signed message can play in the network collective dynamics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neural%20signature" title="neural signature">neural signature</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20fingerprint" title=" neural fingerprint"> neural fingerprint</a>, <a href="https://publications.waset.org/abstracts/search?q=processing%20based%20on%20signal%20identification" title=" processing based on signal identification"> processing based on signal identification</a>, <a href="https://publications.waset.org/abstracts/search?q=self-organizing%20neural%20network" title=" self-organizing neural network"> self-organizing neural network</a> </p> <a href="https://publications.waset.org/abstracts/20408/influence-of-the-refractory-period-on-neural-networks-based-on-the-recognition-of-neural-signatures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20408.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">492</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">202</span> Bioproduction of Phytohormones by Liquid Fermentation Using a Mexican Strain of Botryodiplodia theobromae</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laredo%20Alcal%C3%A1%20Elan%20I%C3%B1aky">Laredo Alcalá Elan Iñaky</a>, <a href="https://publications.waset.org/abstracts/search?q=Hernandez%20Castillo%20Daniel"> Hernandez Castillo Daniel</a>, <a href="https://publications.waset.org/abstracts/search?q=Martinez%20Hernandez%20Jos%C3%A9%20Luis"> Martinez Hernandez José Luis</a>, <a href="https://publications.waset.org/abstracts/search?q=Arredondo%20Valdes%20Roberto"> Arredondo Valdes Roberto</a>, <a href="https://publications.waset.org/abstracts/search?q=Gonzalez%20Gallegos%20Esmeralda"> Gonzalez Gallegos Esmeralda</a>, <a href="https://publications.waset.org/abstracts/search?q=Anguiano%20Cabello%20Julia%20Cecilia"> Anguiano Cabello Julia Cecilia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Plant hormones are a group of molecules that control different processes ranging from the growth and development of the plant until their response to biotic and abiotic stresses.

Quantification of the metabolites was performed using high performance liquid chromatography techniques. The results showed that a microbial broth with at least five different types of plant hormones was obtained: gibberellic acid, zeatin, kinetin, indoleacetic acid and jasmonic acid, the last one was higher than the others metabolites produced. The production of such hormones using a single type of microorganism could be in the future a great alternative to reduce production costs and similarly reduce the use of synthetic chemicals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biosystem" title="biosystem">biosystem</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20hormones" title=" plant hormones"> plant hormones</a>, <a href="https://publications.waset.org/abstracts/search?q=Botryodiplodia%20theobromae" title=" Botryodiplodia theobromae"> Botryodiplodia theobromae</a>, <a href="https://publications.waset.org/abstracts/search?q=fermentation" title=" fermentation"> fermentation</a> </p> <a href="https://publications.waset.org/abstracts/43134/bioproduction-of-phytohormones-by-liquid-fermentation-using-a-mexican-strain-of-botryodiplodia-theobromae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43134.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">403</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">201</span> Pollution Analysis of the Basin High in the Bogota River, Colombia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luis%20Felipe%20Pinzon%20Uribe">Luis Felipe Pinzon Uribe</a>, <a href="https://publications.waset.org/abstracts/search?q=Hernando%20Sotelo%20Rojas"> Hernando Sotelo Rojas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The water is an essential factor for the development and the conservation of biological diversity in Colombia; its abundant natural wealth has its origin in their water sources. These during the past few years have been altered by anthropogenic activities, in particular pollutants such as heavy metals, given its ability to infiltrate the sediments reducing its natural capacity of absorption and clean of the ecosystem. The pollutant loads by bio-accumulation remain in the ecosystem for many years; the Bogota River, located in the Cundinamarca Department, is an example of this process. Since that form in the Villapinzón municipality up to its mouth in the Magdalena River, in the Girardot municipality, along with its route it receives large amount of polluted waters from different sources. The study focused on five points of the high basin of the river; this allowed the analysis of the impact that generates the economic development of the neighboring municipalities and where the poor conditions of the ecosystem, along with low levels of oxygen generates the high values of BOD, dissolved QOD, SS TSS and DS. They have been decisive factors in the decline of the species of its own and a decrease in the supply of the eco-services. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anthropic%20activities" title="anthropic activities">anthropic activities</a>, <a href="https://publications.waset.org/abstracts/search?q=wastes%20water" title=" wastes water"> wastes water</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title=" water quality"> water quality</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a> </p> <a href="https://publications.waset.org/abstracts/64901/pollution-analysis-of-the-basin-high-in-the-bogota-river-colombia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64901.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">342</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">200</span> Evaluation of Water Quality on the Strength of Simple Concrete: Case Study of Wells in Jipijapa, Manabí, Ecuador</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Julio%20Cesar%20Pino%20Tarrag%C3%B3">Julio Cesar Pino Tarragó</a>, <a href="https://publications.waset.org/abstracts/search?q=Dunia%20Lisbet%20Dom%C3%ADnguez%20G%C3%A1lvez"> Dunia Lisbet Domínguez Gálvez</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Alfonso%20Moreno%20Ponce"> Luis Alfonso Moreno Ponce</a>, <a href="https://publications.waset.org/abstracts/search?q=Jhony%20Julio%20Regalado%20Jalca"> Jhony Julio Regalado Jalca</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study examines the impact of three distinct types of water on the compressive strength of plain concrete, focusing on samples from wells in Jipijapa, Manabí, Ecuador: Joa water, characterized by high sulfur content; Chade 1 water, with low sulfur content; and Chade 2 water, which is highly brackish. 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">199</span> The Game of Dominoes as Teaching-Learning Method of Basic Concepts of Differential Calculus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luis%20Miguel%20M%C3%A9ndez%20D%C3%ADaz">Luis Miguel Méndez Díaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article, a mathematics teaching-learning strategy will be presented, specifically differential calculus in one variable, in a fun and competitive space in which the action on the part of the student is manifested and not only the repetition of information on the part of the teacher. Said action refers to motivating, problematizing, summarizing, and coordinating a game of dominoes whose thematic cards are designed around the basic and main contents of differential calculus. The strategies for teaching this area are diverse and precisely the game of dominoes is one of the most used strategies in the practice of mathematics because it stimulates logical reasoning and mental abilities. The objective on this investigation is to identify the way in which the game of dominoes affects the learning and understanding of fundamentals concepts of differential calculus in one variable through experimentation carried out on students of the first semester of the School of Engineering and Sciences of the Technological Institute of Monterrey Campus Querétaro. Finally, the results of this study will be presented and the use of this strategy in other topics around mathematics will be recommended to facilitate logical and meaningful learning in students. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collaborative%20learning" title="collaborative learning">collaborative learning</a>, <a href="https://publications.waset.org/abstracts/search?q=logical-mathematical%20intelligence" title=" logical-mathematical intelligence"> logical-mathematical intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20games" title=" mathematical games"> mathematical games</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20intelligences" title=" multiple intelligences"> multiple intelligences</a> </p> <a href="https://publications.waset.org/abstracts/164819/the-game-of-dominoes-as-teaching-learning-method-of-basic-concepts-of-differential-calculus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164819.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">84</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">198</span> Application Methodology for the Generation of 3D Thermal Models Using UAV Photogrammety and Dual Sensors for Mining/Industrial Facilities Inspection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Javier%20Sedano-Cibri%C3%A1n">Javier Sedano-Cibrián</a>, <a href="https://publications.waset.org/abstracts/search?q=Julio%20Manuel%20de%20Luis-Ruiz"> Julio Manuel de Luis-Ruiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Rub%C3%A9n%20P%C3%A9rez-%C3%81lvarez"> Rubén Pérez-Álvarez</a>, <a href="https://publications.waset.org/abstracts/search?q=Ra%C3%BAl%20Pereda-Garc%C3%ADa"> Raúl Pereda-García</a>, <a href="https://publications.waset.org/abstracts/search?q=Beatriz%20Malag%C3%B3n-Pic%C3%B3n"> Beatriz Malagón-Picón</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Structural inspection 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">197</span> Performance and Specific Emissions of an SI Engine Using Anhydrous Ethanol–Gasoline Blends in the City of Bogota</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Garc%C3%ADa%20Mariaca">Alexander García Mariaca</a>, <a href="https://publications.waset.org/abstracts/search?q=Rodrigo%20Morillo%20Casta%C3%B1o"> Rodrigo Morillo Castaño</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Rol%C3%B3n%20R%C3%ADos"> Juan Rolón Ríos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The government of Colombia has promoted the use of biofuels in the last 20 years through laws and resolutions, which regulate their use, with the objective to improve the atmospheric air quality and to promote Colombian agricultural industry. However, despite the use of blends of biofuels with fossil fuels, the air quality in large cities does not get better, this deterioration in the air is mainly caused by mobile sources that working with spark ignition internal combustion engines (SI-ICE), operating with a mixture in volume of 90 % gasoline and 10 % ethanol called E10, that for the case of Bogota represent 84 % of the fleet. Another problem is that Colombia has big cities located above 2200 masl and there are no accurate studies on the impact that the E10 mixture could cause in the emissions and performance of SI-ICE. This study aims to establish the optimal blend between gasoline ethanol in which an SI engine operates more efficiently in urban centres located at 2600 masl. The test was developed on SI engine four-stroke, single cylinder, naturally aspirated and with carburettor for the fuel supply using blends of gasoline and anhydrous ethanol in different ratios E10, E15, E20, E40, E60, E85 and E100. These tests were conducted in the city of Bogota, which is located at 2600 masl, with the engine operating at 3600 rpm and at 25, 50, 75 and 100% of load. The results show that the performance variables as engine brake torque, brake power and brake thermal efficiency decrease, while brake specific fuel consumption increases with the rise in the percentage of ethanol in the mixture. On the other hand, the specific emissions of CO2 and NOx present increases while specific emissions of CO and HC decreases compared to those produced by gasoline. From the tests, it is concluded that the SI-ICE worked more efficiently with the E40 mixture, where was obtained an increases of the brake power of 8.81 % and a reduction on brake specific fuel consumption of 2.5 %, coupled with a reduction in the specific emissions of CO2, HC and CO in 9.72, 52.88 and 76.66 % respectively compared to the results obtained with the E10 blend. This behaviour is because the E40 mixture provides the appropriate amount of the oxygen for the combustion process, which leads to better utilization of available energy in this process, thus generating a comparable power output to the E10 mixing and producing lower emissions CO and HC with the other test blends. Nevertheless, the emission of NOx increases in 106.25 %. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emissions" title="emissions">emissions</a>, <a href="https://publications.waset.org/abstracts/search?q=ethanol" title=" ethanol"> ethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=gasoline" title=" gasoline"> gasoline</a>, <a href="https://publications.waset.org/abstracts/search?q=engine" title=" engine"> engine</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a> </p> <a href="https://publications.waset.org/abstracts/59572/performance-and-specific-emissions-of-an-si-engine-using-anhydrous-ethanol-gasoline-blends-in-the-city-of-bogota" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59572.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">323</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">196</span> Study of the Influence of Nozzle Length and Jet Angles on the Air Entrainment by Plunging Water Jets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Luis%20Mu%C3%B1oz-Cobo%20Gonz%C3%A1lez">José Luis Muñoz-Cobo González</a>, <a href="https://publications.waset.org/abstracts/search?q=Sergio%20Chiva%20Vicent"> Sergio Chiva Vicent</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Harby%20Mohamed"> Khaled Harby Mohamed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> When a vertical liquid jet plunges into a liquid surface, after passing through a surrounding gas phase, it entrains a large amount of gas bubbles into the receiving pool, and it forms a large submerged two-phase region with a considerable interfacial area.

The paper will examine how two media texts perform counter-hegemonic discourses against institutionalized concepts on citizenship. The article looks at Documented (2014), a documentary film, written and directed by Jose Antonio Vargas, a Pulitzer-winning journalist-turned-activist and a self-proclaimed undocumented immigrant; and DefineAmerican.com, an online media platform that articulates the convergence of multiple voices and discourses about post-industrial and post-semiotic citizenship. As sites of meaning production, the two media texts perform counter-narratives that inspire new forms of mediated social activism and postcolonial identities. The paper argues that a closer introspection of the media texts reveals emotional, thematic and ideological claims to an interrogation of a diasporic discourse on redefining the rules of inclusion and exclusion within the postmodern dialogic of citizenship. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=counter-narratives" title="counter-narratives">counter-narratives</a>, <a href="https://publications.waset.org/abstracts/search?q=documentary%20filmmaking" title=" documentary filmmaking"> documentary filmmaking</a>, <a href="https://publications.waset.org/abstracts/search?q=postmodern%20citizenship" title=" postmodern citizenship"> postmodern citizenship</a>, <a href="https://publications.waset.org/abstracts/search?q=diaspora%20media" title=" diaspora media"> diaspora media</a> </p> <a href="https://publications.waset.org/abstracts/47554/documenting-the-undocumented-performing-counter-narratives-on-citizenship" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47554.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">321</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">194</span> Selective Fermentations of Monosaccharides by Osmotolerant Yeast Cultures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elizabeth%20Loza-Valerdi">Elizabeth Loza-Valerdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Victor%20Pardi%C3%B1as-Rios"> Victor Pardiñas-Rios</a>, <a href="https://publications.waset.org/abstracts/search?q=Arnulfo%20Pluma-Pluma"> Arnulfo Pluma-Pluma</a>, <a href="https://publications.waset.org/abstracts/search?q=Andres%20Breton-Toral"> Andres Breton-Toral</a>, <a href="https://publications.waset.org/abstracts/search?q=Julio%20Cercado-Jaramillo"> Julio Cercado-Jaramillo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purification processes for mixtures of isomeric monosaccharides using industrial chromatographic methods poses a serious technical challenge. Mixtures of 2 or 3 monosaccharides are difficult to separate by strictly physical or chemical techniques. Differential fermentation by microbial cultures is an increasingly interesting way of selective enrichment in a particular kind of monosaccharides when a mixture of them is present in the solution, and only one has economical value. Osmotolerant yeast cultures provide an interesting source of biocatalysts for the selective catabolism of monosaccharides in media containing high concentrations of total soluble sugars. A collection of 398 yeast strains has been obtained using endemic and unique sources of fruit juices, industrial syrups, honey, and other high sugar content substrates, either natural or man made, products and by-products from Mexico. The osmotolerance of the strains was assessed by plate assay both in glucose (20-40-60%w/w). Strains were classified according to their osmotolerance in low, medium or highly tolerant to high glucose concentrations. The purified cultures were tested by their ability to growth in a solid plate media or liquid media of Yeas Nitrogen Base (YNB), added with specific monosaccharides as sole carbon source (glucose, galactose, lactose and fructose). Selected strains were subsequently tested in fermentation experiments with mixtures of two monosaccharides (galactose/glucose and glucose/fructose). Their ability to grow and selectively catabolize one monosaccharide was evaluated. Growth, fermentation activity and products of metabolism were determined by plate counts, CO2 production, turbidity and chromatographic analysis by HPLC. Selective catabolism of one monosaccharide in liquid media containing two monosaccharides was confirmed for 8 strains. Ion Exchange chromatographic processes were used in production of high fructose or galactose syrup. Laboratory scale processes for the production of fructose or galactose enriched syrups is now feasible, with important applications in food (like high fructose syrup as edulcorant) and fermentation technology (for GOS production). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=osmotolerant%20yeasts" title="osmotolerant yeasts">osmotolerant yeasts</a>, <a href="https://publications.waset.org/abstracts/search?q=selective%20metabolism" title=" selective metabolism"> selective metabolism</a>, <a href="https://publications.waset.org/abstracts/search?q=fructose%20syrup" title=" fructose syrup"> fructose syrup</a>, <a href="https://publications.waset.org/abstracts/search?q=GOS" title=" GOS"> GOS</a> </p> <a href="https://publications.waset.org/abstracts/17948/selective-fermentations-of-monosaccharides-by-osmotolerant-yeast-cultures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17948.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">449</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">193</span> Comparison of the Performance of a Brake Energy Regeneration System in Hybrid Vehicles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Miguel%20Arlenzo%20Duran%20Sarmiento">Miguel Arlenzo Duran Sarmiento</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Alfonso%20Del%20Portillo%20Vald%C3%A9s"> Luis Alfonso Del Portillo Valdés</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Borras%20Pinilla"> Carlos Borras Pinilla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Brake energy regeneration systems have the capacity to transform part of the vehicle's kinetic energy during deceleration into useful energy. These systems can be implemented in hybrid vehicles, which can be electric or hydraulic in type, and contribute to reducing the energy required to propel the vehicle thanks to the accumulation of energy. This paper presents the modeling and simulation of a braking energy regeneration system applied in hydraulic hybrid vehicles configured in parallel, the modeling and simulation were performed in Simulink of Matlab, where a performance comparison of the regenerated torque as a function of vehicle load, the displacement of the hydraulic regeneration device and the vehicle speed profile. The speed profiles used in the simulation are standard profiles such as the NEDC and WLTP profiles. The vehicle loads range from 1500 kg to 12000 kg.

Over the last decades, considerable effort has been carried out in order to obtain quieter aircraft solutions, whether by changing the original design or investigating more silent maneuvers. The noise propagated by rotating surfaces is one of the most important sources of annoyance, being present in most aerial vehicles. Bearing this is mind, CEIIA developed a new computational chain for noise prediction with in-house software tools to obtain solutions in relatively short time without using excessive computer resources. This work is based on the new acoustic tool, which aims to predict the rotor noise generated during steady and maneuvering flight, making use of the flexibility of the C language and the advantages of GPU programming in terms of velocity. The acoustic tool is based in the Formulation 1A of Farassat, capable of predicting two important types of noise: the loading and thickness noise. The present work describes the most important features of the acoustic tool, presenting its most relevant results and framework analyses for helicopters and UAV quadrotors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rotor%20noise" title="rotor noise">rotor noise</a>, <a href="https://publications.waset.org/abstracts/search?q=acoustic%20tool" title=" acoustic tool"> acoustic tool</a>, <a href="https://publications.waset.org/abstracts/search?q=GPU%20Programming" title=" GPU Programming"> GPU Programming</a>, <a href="https://publications.waset.org/abstracts/search?q=UAV%20noise" title=" UAV noise"> UAV noise</a> </p> <a href="https://publications.waset.org/abstracts/16738/a-new-computational-tool-for-noise-prediction-of-rotating-surfaces-fact" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16738.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">401</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">191</span> Bibliometrics of 'Community Garden' and Associated Keywords</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guilherme%20Reis%20Ranieri">Guilherme Reis Ranieri</a>, <a href="https://publications.waset.org/abstracts/search?q=Guilherme%20Leite%20Gaudereto"> Guilherme Leite Gaudereto</a>, <a href="https://publications.waset.org/abstracts/search?q=Michele%20Toledo"> Michele Toledo</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Fernando%20Amato-Lourenco"> Luis Fernando Amato-Lourenco</a>, <a href="https://publications.waset.org/abstracts/search?q=Thais%20Mauad"> Thais Mauad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Given the importance to urban sustainability and the growing relevance of the term ‘community garden’, this paper aims to conduct a bibliometric analysis of the term. Using SCOPUS as database, we analyzed 105 articles that contained the keywords ‘community garden’, and conducted a cluster analysis with the associated keywords.

To do so, will be presented initially the idea of the public sphere (by Jürgen Habermas), showing how it is presented as an interface between the citizen and the state (or the private and public) and how important is it in a deliberative democracy. Based on this paradigm, the traditional perception of the role of public information (such as system functional element) and on the possibility of media regulation will be exposed, due to the public nature of their activity. A critical argument will then be displayed from two different perspectives: a) the formal function of the current media information, considering that the digital age has fragmented the information access; b) the concept of a constructive democracy, which reduces the need for representation, changing the strategic importance of the public sphere. The question to be addressed (based on the comparative law) is if the regulation is justified in a polycentric democracy, especially when it operates under the digital age (with immediate and virtual communication). The proposal is to be presented in the sense that even in a twenty-first century the media in a democratic rule of law still has an extremely important role and may be subject to regulation, but this should be on terms very different (and narrower) from those usually defended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constructive%20democracy" title="constructive democracy">constructive democracy</a>, <a href="https://publications.waset.org/abstracts/search?q=media" title=" media"> media</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20age" title=" digital age"> digital age</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20sphere" title=" public sphere"> public sphere</a> </p> <a href="https://publications.waset.org/abstracts/25585/media-regulation-and-public-sphere-in-the-digital-age-an-analysis-in-the-light-of-constructive-democracy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25585.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">380</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">188</span> Modification and Surface Characterization of the Co20Cr15W10Ni Alloy for Application as Biomaterial</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fernanda%20A.%20Vechietti">Fernanda A.

Their biocompatibility and lack of corrosion are also prominent features of this alloy. One of the most effective and simple ways to protect metal’s surfaces are treatments, such as electrochemical oxidation by passivation, which is used as a protect release of metallic ions. Another useful treatment is the electropolishing, which is used to reduce the carbide concentration and protrusion at the implanted surface. Electropolishing is a cheap and effective method for treatment of implants, which generally has complex geometries. The purpose of this study is surface modification of the alloy CoCr(ASTM F90-09) by different methods: polishing, electro polishing, passivation and heat treatment for application as biomaterials. The modification of the surface was studied and characterized by SEM, profilometry, wettability and compared to the surface of the samples untreated. The heat treatment and of passivation increased roughness (0.477 µm and 0.825 µm) the samples in relation the sample electropolished and polished(0.131 µm and 0.274 µm) and were observed the improve wettability’s with the increase the roughness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomaterial" title="biomaterial">biomaterial</a>, <a href="https://publications.waset.org/abstracts/search?q=CoCr" title=" CoCr"> CoCr</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20treatment" title=" surface treatment"> surface treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20%0D%0Atreatment" title=" heat treatment"> heat treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=roughness" title=" roughness"> roughness</a> </p> <a href="https://publications.waset.org/abstracts/17556/modification-and-surface-characterization-of-the-co20cr15w10ni-alloy-for-application-as-biomaterial" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17556.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">543</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">187</span> Ultra-High Frequency Passive Radar Coverage for Cars Detection in Semi-Urban Scenarios</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pedro%20G%C3%B3mez-del-Hoyo">Pedro Gómez-del-Hoyo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose-Luis%20B%C3%A1rcena-Humanes"> Jose-Luis Bárcena-Humanes</a>, <a href="https://publications.waset.org/abstracts/search?q=Nerea%20del-Rey-Maestre"> Nerea del-Rey-Maestre</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa-Pilar%20Jarabo-Amores"> María-Pilar Jarabo-Amores</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Mata-Moya"> David Mata-Moya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A study of achievable coverages using passive radar systems in terrestrial traffic monitoring applications is presented.

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.

Such a situation also affects the evolution and effectiveness of their treatments. In many cases, the solution to this problem involves extra challenges, since many patients need to rest quietly (or remain in bed) to their being contagious. Considering the weak health condition in which usually are these kinds, keeping them motivated and quiet represents an important challenge for nurses and caregivers. This article presents a mobile ubiquitous game called MagicRace, which allows hospitalized kinds to interact socially with one another without putting to risk their sensitive health conditions. The game does not require a communication infrastructure at the hospital, but instead, it uses a mobile ad hoc network composed of the handheld devices used by the kids to play. The usability and performance of this application was tested in two different sessions. The preliminary results show that users experienced positive feelings from this experience. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ubiquitous%20game" title="ubiquitous game">ubiquitous game</a>, <a href="https://publications.waset.org/abstracts/search?q=children%27s%20emotional%20support" title=" children's emotional support"> children's emotional support</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20isolation" title=" social isolation"> social isolation</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20collaborative%20interactions" title=" mobile collaborative interactions"> mobile collaborative interactions</a> </p> <a href="https://publications.waset.org/abstracts/2537/providing-emotional-support-to-children-under-long-term-health-treatments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2537.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">184</span> Collaboration and Automatic Tutoring as a Learning Strategy: A Case Study in Programming Courses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luis%20H.%20Gonzalez-Guerra">Luis H.

They have been familiar with digital technology throughout their lives so they have developed skills that should be naturally adopted as part of their study strategies. New learning styles require taking in consideration the use of models that support and promote student motivation for learning and development of their creative thinking skills. To achieve student learning in programming courses, different strategies are used. One of them is a collaboration between students, which is a tool which faculty can take advantage of when teaching these kinds of courses. Moreover, cooperation is an essential skill that society should reinforce in order to promote a healthy social environment and cohabitation. Nevertheless, students will still require support and advice to get a complete and correct programming solution to successfully address and solve the problems given throughout the course. This paper present a model where collaboration between students is associated with an automatic tutoring platform providing an excellent approach for the individual learning in collaborative activities in programming courses, and also motivates students to increase their knowledge regarding the topics covered in the classroom. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automatic%20tutoring" title="automatic tutoring">automatic tutoring</a>, <a href="https://publications.waset.org/abstracts/search?q=collaboration%20learning" title=" collaboration learning"> collaboration learning</a>, <a href="https://publications.waset.org/abstracts/search?q=creative%20thinking" title=" creative thinking"> creative thinking</a>, <a href="https://publications.waset.org/abstracts/search?q=motivation" title=" motivation"> motivation</a> </p> <a href="https://publications.waset.org/abstracts/74564/collaboration-and-automatic-tutoring-as-a-learning-strategy-a-case-study-in-programming-courses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74564.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">272</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">183</span> Influence of Drying Method in Parts of Alumina Obtained for Rapid Prototyping and Uniaxial Dry Pressing </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20O.%20Muniz">N.

Many in vitro and in vivo studies have revealed the significance of the porous structure of the biomaterials on the promotion of bone ingrowth. The use of Rapid Prototyping in the manufacture of ceramics in the biomedical area has increased in recent years and few studies are conducted on obtaining alumina pieces. The aim of this work was the study of alumina pieces obtained by 3D printing and uniaxial dry pressing (DP) in order to evaluate porosity achieved by this two different techniques. Also, the influence of the powder drying process was determined. The row alumina powders were drying by freeze drying and oven. Apparent porosity, apparent density, retraction after thermal treatment were evaluated. The porosity values obtained by DP, regardless of method of drying powders, were much lower than those obtained by RP as expected. And for the prototyped samples, the method of powder drying significantly influenced porosities, reached 48% for drying oven versus 65% for freeze-drying. Therefore, the method of 3D printing, using different powder drying, allows a better control over the porosity. <p class="card-text"><strong>Keywords:</strong> <a
