Considered it a semi-regenerative reformer, with four reactors in series intercalated with four furnaces, two heat exchanges, one product separator and one recycle compressor. A simplified reactional system was considered, involving only ten chemical compounds related through five reactions. The considered process was the applied to aromatics production (benzene, toluene, and xylene). The models developed to diverse equipment were interconnecting in a simulator that consists of a computer program elaborate in FORTRAN 77. The simulation of the global model representative of reformer unity achieved results that are compatibles with the literature ones. It was then possible to study the effects of operational variables in the products concentration and in the performance of the unity equipment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=catalytic%20reforming" title="catalytic reforming">catalytic reforming</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=petrochemical%20engineering" title=" petrochemical engineering"> petrochemical engineering</a> </p> <a href="https://publications.waset.org/abstracts/22923/naphtha-catalytic-reform-modeling-and-simulation-of-unity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22923.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">515</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">94</span> Microscopic Visualization of the Ice Slurry Ice Particles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20Jos%C3%A9%20Mil%C3%B3n%20Guzm%C3%A1n">Juan José Milón Guzmán</a>, <a href="https://publications.waset.org/abstracts/search?q=Herbert%20Jes%C3%BAs%20Del%20Carpio%20Beltr%C3%A1n"> Herbert Jesús Del Carpio Beltrán</a>, <a href="https://publications.waset.org/abstracts/search?q=Sergio%20Leal%20Braga"> Sergio Leal Braga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Visualizations of ice particles of ice slurry are performed.

In this work, a new family of flying wing airfoils is designed for low Reynolds number flows, typical of small-middle UAVs. Camber, thickness and their maximum positions in the chord are variables used for the airfoil geometry optimization. Aerodynamic non-dimensional coefficients were obtained by the well-established Panel Method. High efficient airfoils with small pitch moment coefficient are obtained from the analysis described and its aerodynamic polars are plotted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airfoil%20design" title="airfoil design">airfoil design</a>, <a href="https://publications.waset.org/abstracts/search?q=flying%20wing" title=" flying wing"> flying wing</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20Reynolds%20number" title=" low Reynolds number"> low Reynolds number</a>, <a href="https://publications.waset.org/abstracts/search?q=tailless%20aircraft" title=" tailless aircraft"> tailless aircraft</a>, <a href="https://publications.waset.org/abstracts/search?q=UAV" title=" UAV"> UAV</a> </p> <a href="https://publications.waset.org/abstracts/33946/a-new-family-of-flying-wing-low-reynolds-number-airfoils" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33946.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">629</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">85</span> Social Impacts of Gentrification: Protest and Resistance: A Case Study in Monterrey’s City Center</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paulina%20Ramirez%20Leal">Paulina Ramirez Leal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Current debates have examined the effects of market-oriented development on gentrification, as well as the role of urban renewal, interventions, and planning policy in exacerbating this phenomenon. Despite the growing body of research recognizing the social impacts of gentrification, to date, there has been very little research directly investigating how resisting gentrification increases social cohesion, a crucial dimension of urban resilience. This contribution set out to explore these social impacts while identifying the different forms of protest and expressions of resistance to gentrification in Monterrey’s city center. The methods employed include documentary analysis and qualitative methods such as surveys and photographic documentation. Monterrey’s city center's ongoing process of gentrification illustrates the impacts of planning policies, specifically TOD. Some of the unintended consequences of the policy have resulted in inhabitants facing forced inner migration and displacement caused by vandalism of their homes and neighborhoods, as well as losing part of their urban identity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gentrification" title="gentrification">gentrification</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20impacts" title=" social impacts"> social impacts</a>, <a href="https://publications.waset.org/abstracts/search?q=neighborhood%20identity" title=" neighborhood identity"> neighborhood identity</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20resilience" title=" urban resilience"> urban resilience</a>, <a href="https://publications.waset.org/abstracts/search?q=Monterrey%E2%80%99s%20City%20Center" title=" Monterrey’s City Center"> Monterrey’s City Center</a> </p> <a href="https://publications.waset.org/abstracts/158176/social-impacts-of-gentrification-protest-and-resistance-a-case-study-in-monterreys-city-center" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158176.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">105</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">84</span> A Motion Dictionary to Real-Time Recognition of Sign Language Alphabet Using Dynamic Time Warping and Artificial Neural Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcio%20Leal">Marcio Leal</a>, <a href="https://publications.waset.org/abstracts/search?q=Marta%20Villamil"> Marta Villamil</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Computacional recognition of sign languages aims to allow a greater social and digital inclusion of deaf people through interpretation of their language by computer.

To have a clear picture of the drawback and competitive alternative, this study has explored two scenarios, namely Scenario a and Scenario b. The Scenario a indicates that in the year 2020 the GHG emissions would be 823,498.00 million tons (Mt) with a 2020 final demand and proposed fuel mix such as by the Five-Fuel Diversification Strategy. In contrast, as an alternative, the Scenario b with biofuel potentials indicates that the substitution of coal energy by 5%, 10%, and 15%, respectively, with biofuel, would reduce the GHG emissions from 374,551.00, 405,118.00, and 823,498.00 million tons to 339,964.00, 329,834.00, and 305,288.00 million tons, respectively, by the present fuel mix, business-as-usual fuel mix, and proposed fuel mix up to the year 2020. Therefore, this study has explored a healthy alternative by introducing biofuel renewable energy option instead of conventional energy utilization in the power generation with environmental aspect in minds. This study effort would lessen the gap between GHG mitigation and future sustainable development and would useful to formulate effective renewable energy strategy in Malaysia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy" title="energy">energy</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20impacts" title=" environmental impacts"> environmental impacts</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=biofuel" title=" biofuel"> biofuel</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20policy" title=" energy policy "> energy policy </a> </p> <a href="https://publications.waset.org/abstracts/18495/environmental-sustainability-a-renewable-energy-prospect-with-a-biofuel-alternative" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18495.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">486</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">82</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">81</span> Numerical Study for the Estimation of Hydrodynamic Current Drag Coefficients for the Colombian Navy Frigates Using Computational Fluid Dynamics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mauricio%20Gracia">Mauricio Gracia</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Leal"> Luis Leal</a>, <a href="https://publications.waset.org/abstracts/search?q=Bharat%20Verma"> Bharat Verma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Computational fluid dynamics (CFD) has become nowadays an important tool in the process of hydrodynamic design of modern ships. CFD is used to model any phenomena related to fluid flow in a control volume like a ship or any offshore structure in the sea. In the present study, the current force drag coefficients for a Colombian Navy Frigate in deep and shallow water are estimated through the application of CFD. The study shows the process of simulating the ship current drag coefficients using the CFD simulations method, which is conducted using STAR-CCM+ software package. The Almirante Padilla class Frigate ship scale model is investigated. The results show the ship current drag coefficient calculated considering a current speed of 1 knot with a 90° drift angle for the full-scale ship. Predicted results were compared against the current drag coefficients published in the Lloyds register OCIMF report. It is shown that the simulation results agree fairly well with the published results and that STAR-CCM+ code can predict current drag coefficients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD" title="CFD">CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=current%20draft%20coefficient" title=" current draft coefficient"> current draft coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=STAR-CCM%2B" title=" STAR-CCM+"> STAR-CCM+</a>, <a href="https://publications.waset.org/abstracts/search?q=OCIMF" title=" OCIMF"> OCIMF</a>, <a href="https://publications.waset.org/abstracts/search?q=Bollard%20pull" title=" Bollard pull"> Bollard pull</a> </p> <a href="https://publications.waset.org/abstracts/132520/numerical-study-for-the-estimation-of-hydrodynamic-current-drag-coefficients-for-the-colombian-navy-frigates-using-computational-fluid-dynamics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132520.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">173</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">80</span> Experimental Measurements of Fire Retardants on Plywood at Fire Test</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gisele%20C.%20A.%20Martins">Gisele C.

Thus, becomes evident the need for research aiming to fit these in safety standards. This study aims to evaluate the efficiency of two new fire retardant products produced by a Brazilian industry. Tests were performed on plywood panels of Pinus spp previously immersed, varying the products concentrations and compared with untreated samples. The test used to evaluate the flame spread in a panel was the modified Schlyter test. The product in question was proved efficient, before and after shutting off the burner. Comparing panels with the panels without treatment, there was a decrease of 400% of the height of the flame spread on the treated ones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fire%20retardant" title="fire retardant">fire retardant</a>, <a href="https://publications.waset.org/abstracts/search?q=flame%20spread" title=" flame spread"> flame spread</a>, <a href="https://publications.waset.org/abstracts/search?q=plywood" title=" plywood"> plywood</a>, <a href="https://publications.waset.org/abstracts/search?q=wood-based%20material" title=" wood-based material"> wood-based material</a> </p> <a href="https://publications.waset.org/abstracts/18989/experimental-measurements-of-fire-retardants-on-plywood-at-fire-test" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18989.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">433</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">79</span> English Theticity and Focus Expression in Spanish Heritage Speakers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sebastian%20Leal-Arenas">Sebastian Leal-Arenas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> English uses in-situ Nuclear Stress (NS) to express the meanings of theticity and focus. The NS is phonetically represented by an increase in duration, intensity, and pitch range. On the other hand, Spanish conveys the same meanings by aligning the constituent that carries the NS to the end of the sentence via word-order movement. However, little is known about heritage speakers’ production of theticity and focus in English or Spanish. The present study investigates heritage speakers’ production of thetic and subject focus statements. Participants (n = 11) were heritage speakers of Spanish with varying proficiency enrolled in a writing course at a university in the United States. In the production task, participants observed contextualized images and uttered a sentence to answer a provided question. Duration, intensity, and F0 peak were the correlates to stress considered in this investigation. Results indicated that participants tended to present an intonation closer to what is expected in English monolinguals in subject-focus statements than in thetic sentences. However, participants with lower Spanish proficiency used in-situ NS placement in thetic statements more often than those with higher proficiency. Results are discussed in terms of the production patterns observed in heritage speakers with emphasis on the role of language dominance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=focus" title="focus">focus</a>, <a href="https://publications.waset.org/abstracts/search?q=heritage%20speakers" title=" heritage speakers"> heritage speakers</a>, <a href="https://publications.waset.org/abstracts/search?q=prosody" title=" prosody"> prosody</a>, <a href="https://publications.waset.org/abstracts/search?q=theticity" title=" theticity"> theticity</a> </p> <a href="https://publications.waset.org/abstracts/175788/english-theticity-and-focus-expression-in-spanish-heritage-speakers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175788.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">71</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">78</span> The Next Game Changer: 3-D Printed Musical Instruments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leonardo%20Ko">Leonardo Ko</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In an era marked by rapid technological innovation, the classical instrument industry nonetheless has not seen significant change.

This study aimed to design and create a practical, effective 3-D printed acoustic violin. A cost-benefit analysis of materials and design is presented in addition to a report on sound tests in which a pool of professional musicians compared the traditional violin to its synthetic counterpart with regard to acoustic properties.

Furthermore, resilience can be described as the ability which allows an individual or group to hold up well before unfavorable situations. This study aimed to identify nursing workers’ resilience at a psychiatric hospital in Brazil. This is an exploratory research with quantitative data approach. The sample consisted of 56 workers, using the Resilience Scale. Of the 56 subjects, 45 (80.4%) were women; 22 (39.2%) were 20- to 40-years-old and 30 (53.6%) were 41- to 60-years-old; 11 (19.6%) were nurses and 45 (80.4%) were technicians or nursing assistants. The results also showed that 50% of subjects showed a high resilience degree and 42.9% an average resilience degree. Thus, it was found that workers seek to develop protective factors in coping with a work environment that does not value the individual subjectivity and does not allow professional development, discouraging workers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=health%20promotion" title="health promotion">health promotion</a>, <a href="https://publications.waset.org/abstracts/search?q=nursing" title=" nursing"> nursing</a>, <a href="https://publications.waset.org/abstracts/search?q=occupational%20health" title=" occupational health"> occupational health</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience" title=" resilience"> resilience</a> </p> <a href="https://publications.waset.org/abstracts/26323/nursing-workers-capacity-of-resilience-at-a-psychiatric-hospital-in-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26323.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">518</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">76</span> Men and Feminism: Social Constructions of Masculinities in Relation to the Feminist Movement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leonardo%20Dias%20Cruz">Leonardo Dias Cruz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The advent of web 2.0 has enabled users to engage in translocal and transtemporal interactions in which meanings can be constantly (re)constructed. The fluidity of such interactions in the time-space spectrum makes it evident that D/discourses are always in movement and that here-and-now discursive practices are always linked to macro Discourses in social structures. Considering these assumptions, this study aims at exploring the social construction of masculinities in light of feminist D/discourses in online interactions. The data used are a series of comments from readers of articles posted in a website for (projected) male audiences. In order to approach the movable and fluid nature of such interactions, I examine the data through the lens of processes of entextualization, social positioning and indexical cues. The analysis explores the interactions as social arenas in which struggles for the control over entextualization processes are clearly noticeable. Moreover, two main stances are perceived: one that legitimates male’s participation in Feminism and one that rejects such participation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=entextualization" title="entextualization">entextualization</a>, <a href="https://publications.waset.org/abstracts/search?q=feminism" title=" feminism"> feminism</a>, <a href="https://publications.waset.org/abstracts/search?q=masculinities" title=" masculinities"> masculinities</a>, <a href="https://publications.waset.org/abstracts/search?q=positionings" title=" positionings"> positionings</a> </p> <a href="https://publications.waset.org/abstracts/33485/men-and-feminism-social-constructions-of-masculinities-in-relation-to-the-feminist-movement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33485.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">467</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> Aerodynamic Design of a Light Long Range Blended Wing Body Unmanned Vehicle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Halison%20da%20Silva%20Pereira">Halison da Silva Pereira</a>, <a href="https://publications.waset.org/abstracts/search?q=Ciro%20Sobrinho%20Campolina%20Martins"> Ciro Sobrinho Campolina Martins</a>, <a href="https://publications.waset.org/abstracts/search?q=Vitor%20Mainenti%20Leal%20Lopes"> Vitor Mainenti Leal Lopes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Long range performance is a goal for aircraft configuration optimization. Blended Wing Body (BWB) is presented in many works of literature as the most aerodynamically efficient design for a fixed-wing aircraft. Because of its high weight to thrust ratio, BWB is the ideal configuration for many Unmanned Aerial Vehicle (UAV) missions on geomatics applications. In this work, a BWB aerodynamic design for typical light geomatics payload is presented. Aerodynamic non-dimensional coefficients are predicted using low Reynolds number computational techniques (3D Panel Method) and wing parameters like aspect ratio, taper ratio, wing twist and sweep are optimized for high cruise performance and flight quality. The methodology of this work is a summary of tailless aircraft wing design and its application, with appropriate computational schemes, to light UAV subjected to low Reynolds number flows leads to conclusions like the higher performance and flight quality of thicker airfoils in the airframe body and the benefits of using aerodynamic twist rather than just geometric. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blended%20wing%20body" title="blended wing body">blended wing body</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20Reynolds%20number" title=" low Reynolds number"> low Reynolds number</a>, <a href="https://publications.waset.org/abstracts/search?q=panel%20method" title=" panel method"> panel method</a>, <a href="https://publications.waset.org/abstracts/search?q=UAV" title=" UAV"> UAV</a> </p> <a href="https://publications.waset.org/abstracts/33948/aerodynamic-design-of-a-light-long-range-blended-wing-body-unmanned-vehicle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33948.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">586</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">74</span> Optimization of the Structural Design for an Irregular Building in High Seismicity Zone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arias%20Fernando">Arias Fernando</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Boj%C3%B3rquez"> Juan Bojórquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Ed%C3%A9n%20Boj%C3%B3rquez"> Edén Bojórquez</a>, <a href="https://publications.waset.org/abstracts/search?q=Alfredo%20Reyes-Salazar"> Alfredo Reyes-Salazar</a>, <a href="https://publications.waset.org/abstracts/search?q=Fernando%20de%20J.%20Velarde"> Fernando de J.

Using the spectral modal method, analyses were conducted to assess the ability of these buildings to withstand seismic forces and other external loads. After performing a detailed analysis of various models, the results were compared based on various engineering parameters, including maximum interstory drift, base shear, displacements, and the total weight of the structures, the latter being considered as an estimate of the cost of the proposed systems. The findings of this study indicate that steel frames stand out as a viable option for tall buildings in question. However, areas of potential improvement were identified, suggesting opportunities for further optimization of the design and seismic resistance of these structures. This study provides a deep and insightful perspective on the optimization of structural systems in tall steel buildings, offering valuable information for engineers and professionals in the field involved in similar projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high%20seismic%20zone" title="high seismic zone">high seismic zone</a>, <a href="https://publications.waset.org/abstracts/search?q=irregular%20buildings" title=" irregular buildings"> irregular buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization%20design" title=" optimization design"> optimization design</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20buildings" title=" steel buildings"> steel buildings</a> </p> <a href="https://publications.waset.org/abstracts/192081/optimization-of-the-structural-design-for-an-irregular-building-in-high-seismicity-zone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192081.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">24</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">73</span> A Dynamic Symplectic Manifold Analysis for Wave Propagation in Porous Media</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20I.%20M.%20Guerra">K.

The paper starts with a given partial differential equation based on the continuity and conservation theorems to describe the traveling wave through the porous body. A solution for this equation is proposed after all boundary, and initial conditions are fixed, and it’s accepted that the solution lies in a manifold U of purely spatial dimensions and that is embedded in the Real n-dimensional manifold, with spatial and kinetic dimensions. It’s shown that the U manifold of lower dimensions than IRna, where it is embedded, inherits properties of the vector spaces existing inside the topology it lies on. Then, a second manifold (U*), embedded in another space called IRnb of stress dimensions, is proposed and there’s a non-degenerative function that maps it into the U manifold. This relation is proved as a transformation in between two corresponding admissible solutions of the differential equation in distinct dimensions and properties, leading to a more visual and intuitive understanding of the whole dynamic process of a stress wave through a porous medium and also highlighting the dimensional invariance of Terzaghi’s theory for any coordinate system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=poremechanics" title="poremechanics">poremechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20dynamics" title=" soil dynamics"> soil dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=symplectic%20geometry" title=" symplectic geometry"> symplectic geometry</a>, <a href="https://publications.waset.org/abstracts/search?q=wave%20propagation" title=" wave propagation"> wave propagation</a> </p> <a href="https://publications.waset.org/abstracts/83917/a-dynamic-symplectic-manifold-analysis-for-wave-propagation-in-porous-media" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83917.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">295</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> Immunostimulant from Biodiversity to Enhance Shrimp Survival against Vibriosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Frank%20Alexis">Frank Alexis</a>, <a href="https://publications.waset.org/abstracts/search?q=Jenny%20Antonia%20Rodriguez%20Leon"> Jenny Antonia Rodriguez Leon</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristobal%20Leonardo%20Dominguez%20Borbor"> Cristobal Leonardo Dominguez Borbor</a>, <a href="https://publications.waset.org/abstracts/search?q=Mery%20Rosario%20Ramirez%20Munoz"> Mery Rosario Ramirez Munoz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The shrimp industry has increased in the last years to the point of becoming one of the most dynamic industries.

In this project, we extracted the fibers from vegetal sources in Ecuador and characterized them using common techniques like XRD, SEM, and then we tested the effect of fibers as immunostimulants for shrimps in-vitro and in-vivo using small aquarium and large pools. Our results demonstrate that vegetal fibers can significantly increase the survival of shrimps. Moreover, the production of shrimps in a large pool was significantly increased.

The impact of the mobile app transcends entertainment, as shown by the growing presence of specialized accounts dedicated to providing educational content, particularly as it pertains to language learning. However, the prevailing trend on the platform is vocabulary and grammar acquisition, neglecting a critical component: pronunciation. This study examines English pronunciation materials available on TikTok by taking a comprehensive approach that incorporates established assessment tools, such as the Learning Object Review Instrument and the Framework for Language Learning App Evaluation. Furthermore, novel evaluation categories are introduced to provide a more holistic assessment of these educational resources. 60 English pronunciation videos were part of the analysis. The findings reveal that these audio-visual materials present clear audio bolstered by high-quality video content and automatically generated closed captions. These three components enhance the comprehensibility of the input, making these concise videos valuable assets for language learners. Nevertheless, certain deficiencies are observed, such as the lack of emphasis on specific segments and their relationship with articulators. Improvements and refinements are discussed, as well as their potential utility within the language classroom. This study contributes to the ongoing investigation of multimedia materials used for language teaching and emphasizes the need to adapt pronunciation instruction methods to today’s technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pronunciation" title="pronunciation">pronunciation</a>, <a href="https://publications.waset.org/abstracts/search?q=segments" title=" segments"> segments</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching%20materials" title=" teaching materials"> teaching materials</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a> </p> <a href="https://publications.waset.org/abstracts/175710/english-pronunciation-materials-on-tiktok" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175710.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">86</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">69</span> Modeling of a Stewart Platform for Analyzing One Directional Dynamics for Spacecraft Docking Operations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leonardo%20Herrera">Leonardo Herrera</a>, <a href="https://publications.waset.org/abstracts/search?q=Shield%20B.%20Lin"> Shield B.

In addition, the constant flow of RC generates a lot of interest for study due to the incidence of various natural phenomena, which makes it relevant to characterize their incidence parameters to determine their effect not only at subsoil or terrestrial surface levels but also throughout the atmosphere. To determine the physical parameters of the primary cosmic ray, the implementation of robust algorithms capable of reconstructing the cascade from the measured values is required, with a high level of reliability. Therefore, it is proposed to build a machine learning system that will be fed from the cosmic ray simulations in CORSIKA at different energies that lie in a range [10⁹-10¹²] eV. in order to generate a
