The author Jack London presents various spatial routines of Martin Eden and reveals the involvement of space in realizing American dream: on the one hand, the Berkeley and Oakland cities contribute to Martin’s material success, making his American dream practical, and on the other hand, the two cities involve in the oppression of bourgeoisie ideology to Martin, promoting the domestic imperialization of bourgeoisie ideology represented by American dream. Molded by bourgeoisie ideology in the city, Martin constructed the oriental South Sea, revealing the oversea imperialization of bourgeoisie ideology behind American dream. By exploring the social, historical and political aspects of space, Martin Eden tries to demonstrate the mere material success and imperialism represented by American dream, revealing the fact of the involvement of American dreamin ideological oppression. When Jack London wrote Martin Eden, he had become a famous writer and realized his personal "American dream". He integrated his struggle experience into the protagonist Martin Eden, and also put his critique of the nature of "American dream" in the novel. The concept of the "American Dream" made the United States the land of dreams, and it also made many Americans believe that through personal struggle, they could climb the social ladder. Under the context of rapid growth in economy in the late 19 th century, American dream was reduced to the satisfaction on a material level. When material wealth was fulfilled, many people felt shattered for a variety of reasons, and such a phenomenon was reflected in the literature of disillusionment in 19th-century America.Martin Eden is such a work about disillusion, in which the geographical space becomes the witness of the realization and disillusionment of the protagonist Martin's "American dream". By analyzing the spatial narrative in Martin Eden, this paper reveals that the "American dream" only represents material success for individuals and the imperialization of capitalist ideology, and exposes the ideological nature of the "American Dream". <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martin%20Eden" title="Martin Eden">Martin Eden</a>, <a href="https://publications.waset.org/abstracts/search?q=space" title=" space"> space</a>, <a href="https://publications.waset.org/abstracts/search?q=American%20dream" title=" American dream"> American dream</a>, <a href="https://publications.waset.org/abstracts/search?q=ideology%20of%20imperialism" title=" ideology of imperialism"> ideology of imperialism</a> </p> <a href="https://publications.waset.org/abstracts/153998/on-space-narrative-and-american-dream-in-martin-eden" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153998.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">149</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">534</span> Optimization Model for Support Decision for Maximizing Production of Mixed Fruit Tree Farms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A9s%20I.%20%C3%81vila">Andrés I.

Humans use language to convey ideas, thoughts, and feelings. We can use words for different things for example like asserted, advising, promise, give opinions, hopes, etc. Propaganda is an attempt which seeks to obtain stable behavior to adopt everyone to his everyday life. It also controls the thoughts and attitudes of individuals in social settings permanent. In this research, the writer will discuss about the speech act in a propaganda speech delivered by Martin Luther King Jr. in Washington at Lincoln Memorial on August 28, 1963. 'I Have a Dream' is a public speech delivered by American civil rights activist MLK, he calls from an end to racism in USA. In this research, the writer uses Searle theory to analyze the types of illocutionary speech act that used by Martin Luther King Jr. in his propaganda speech. In this research, the writer uses a qualitative method described in descriptive, because the research wants to describe and explain the types of illocutionary speech acts used by Martin Luther King Jr. in his propaganda speech. The findings indicate that there are five types of speech acts in Martin Luther King Jr. speech. MLK also used direct speech and indirect speech in his propaganda speech. However, direct speech is the dominant speech act that MLK used in his propaganda speech. It is hoped that this research is useful for the readers to enrich their knowledge in a particular field of pragmatic speech acts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=speech%20act" title="speech act">speech act</a>, <a href="https://publications.waset.org/abstracts/search?q=propaganda" title=" propaganda"> propaganda</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Luther%20King%20Jr." title=" Martin Luther King Jr."> Martin Luther King Jr.</a>, <a href="https://publications.waset.org/abstracts/search?q=speech" title=" speech"> speech</a> </p> <a href="https://publications.waset.org/abstracts/45649/an-analysis-of-illocutioary-act-in-martin-luther-king-jrs-propaganda-speech-entitled-i-have-a-dream" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45649.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">441</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">532</span> Ensuring Consistency under the Snapshot Isolation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Roberto%20Val%C3%AAncio">Carlos Roberto Valêncio</a>, <a href="https://publications.waset.org/abstracts/search?q=F%C3%A1bio%20Renato%20de%20Almeida"> Fábio Renato de Almeida</a>, <a href="https://publications.waset.org/abstracts/search?q=Thatiane%20Kawabata"> Thatiane Kawabata</a>, <a href="https://publications.waset.org/abstracts/search?q=Leandro%20Alves%20Neves"> Leandro Alves Neves</a>, <a href="https://publications.waset.org/abstracts/search?q=Julio%20Cesar%20Momente"> Julio Cesar Momente</a>, <a href="https://publications.waset.org/abstracts/search?q=Mario%20Luiz%20Tronco"> Mario Luiz Tronco</a>, <a href="https://publications.waset.org/abstracts/search?q=Angelo%20Cesar%20Colombini"> Angelo Cesar Colombini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> By running transactions under the Snapshot isolation we can achieve a good level of concurrency, specially in databases with high-intensive read workloads. However, Snapshot is not immune to all the problems that arise from competing transactions and therefore no serialization warranty exists. We propose in this paper a technique to obtain data consistency with Snapshot by using some special triggers that we named Daemon Triggers. Besides keeping the benefits of the Snapshot isolation, the technique is specially useful for those database systems that do not have an isolation level that ensures serializability, like Firebird and Oracle. We describe all the anomalies that might arise when using the Snapshot isolation and show how to preclude them with Daemon Triggers. Based on the methodology presented here, it is also proposed the creation of a new isolation level: Daemon Snapshot. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data%20consistency" title="data consistency">data consistency</a>, <a href="https://publications.waset.org/abstracts/search?q=serialization" title=" serialization"> serialization</a>, <a href="https://publications.waset.org/abstracts/search?q=snapshot" title=" snapshot"> snapshot</a>, <a href="https://publications.waset.org/abstracts/search?q=isolation" title=" isolation"> isolation</a> </p> <a href="https://publications.waset.org/abstracts/10560/ensuring-consistency-under-the-snapshot-isolation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10560.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">329</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">531</span> Optimization Model for Support Decision for Maximizing Production of Mixed Fresh Fruit Farms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A9s%20I.%20%C3%81vila">Andrés I.

MSWI bottom ashes are mainly used in road engineering in substitution of the traditional natural aggregates. As the characterization of their mechanical behavior is essential in order to use them, specific studies have been led over the past few years. In the first part of this paper, the mechanical behavior of MSWI bottom ash is studied with triaxial tests. After analysis of the experiment results, the simulation of triaxial tests is carried out by using the software package CESAR-LCPC. As the first approach in modeling of this new class material, the Mohr-Coulomb model was chosen to describe the evolution of material under the influence of external mechanical actions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bottom%20ash" title="bottom ash">bottom ash</a>, <a href="https://publications.waset.org/abstracts/search?q=granular%20material" title=" granular material"> granular material</a>, <a href="https://publications.waset.org/abstracts/search?q=triaxial%20test" title=" triaxial test"> triaxial test</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20behavior" title=" mechanical behavior"> mechanical behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohr-Coulomb%20model" title=" Mohr-Coulomb model"> Mohr-Coulomb model</a>, <a href="https://publications.waset.org/abstracts/search?q=CESAR-LCPC" title=" CESAR-LCPC"> CESAR-LCPC</a> </p> <a href="https://publications.waset.org/abstracts/36317/finite-element-modeling-of-the-mechanical-behavior-of-municipal-solid-waste-incineration-bottom-ash-with-the-mohr-coulomb-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36317.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">310</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">529</span> Postmodernism and Metanarrative: Deconstruction of Narrative in a Song of Ice and Fire Fantasy TV Series</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Narjes%20Azimi">Narjes Azimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It has been a while that narrative and storytelling turned to be the inevitable part of media. The narrative has so many aspects and among those entire aspects, the fantasy genre is consciously challenging one as fantasy readers are used to reading narratives like good versus evil plot. This paper will analyze the ASOIF TV series as a Meta narrative cultural production that deconstructs the elements of a traditional narrative. This study will shade on a grand narrative perspective from poststructuralism point of view. The theoretical framework is structuralism and post structuralism. Lyotard and Barthes are two main poststructuralists and focus of the study. Lyotard grand narrative elements will analyze in this research study. Fantasy genre generated a number of outstanding authors that explore innovative perspectives. Among all these leading authors George R.R Martin is one of the best. George R. R. Martin’s Fantasy a Song of Ice and Fire picturized the brutal world that seven kingdoms struggling for the power. Since 2011 this production has been followed and watched by millions of audiences all around the world. The methodology is the textual analysis of selected scenes. Martin’s distinctive fantasy style which makes it different from other fantasies, yet this shift does not negate how the previous fantasy writers represent the mentioned concepts of war, and etc., but Martin’ fantasy and left the mature audiences full of uncertainty. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=narrative%20theory" title="narrative theory">narrative theory</a>, <a href="https://publications.waset.org/abstracts/search?q=metanarrative" title=" metanarrative"> metanarrative</a>, <a href="https://publications.waset.org/abstracts/search?q=deconstruction" title=" deconstruction"> deconstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=post-structuralism" title=" post-structuralism"> post-structuralism</a>, <a href="https://publications.waset.org/abstracts/search?q=Lyotard" title=" Lyotard"> Lyotard</a>, <a href="https://publications.waset.org/abstracts/search?q=Barthes" title=" Barthes"> Barthes</a> </p> <a href="https://publications.waset.org/abstracts/87831/postmodernism-and-metanarrative-deconstruction-of-narrative-in-a-song-of-ice-and-fire-fantasy-tv-series" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87831.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">528</span> Appliance of the Analytic Hierarchy Process Methodology for the Selection of a Small Modular Reactors to Enhance Maritime Traffic Decarbonisation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sara%20Mart%C3%ADn">Sara Martín</a>, <a href="https://publications.waset.org/abstracts/search?q=Ying%20Jie%20Zheng"> Ying Jie Zheng</a>, <a href="https://publications.waset.org/abstracts/search?q=C%C3%A9sar%20Hueso"> César Hueso</a> </p> <p class="card-text"><strong>Abstract:</strong></p> International shipping is considered one of the largest sources of pollution in the world, accounting for 812 million tons of CO2 emissions in the year 2018. Current maritime decarbonisation is based on the implementation of new fuel alternatives, such as LNG, biofuels, and methanol, among others, which are less polluting as well as less efficient. Despite being a carbon-free and highly-developed technology, nuclear propulsion is hardly discussed as an alternative. Scientifically, it is believed that Small Modular Reactors (SMR) could be a promising solution to decarbonized maritime traffic due to their small dimensions and safety capabilities. However, as of today, there are no merchant ships powered by nuclear systems. Therefore, this project aims to understand the challenges of the development of nuclear-fuelled vessels by analysing all SMR designs to choose the most suitable one. In order not to fall into subjectivities, the Analytic Hierarchy Process (AHP) will be used to make the selection. This multiple-criteria evaluation technique analyses complex decisions by pairwise comparison of a number of evaluation criteria that can be applied to each SMR. The state-of-the-art 72 SMRs presented by the International Atomic Energy Agency (IAEA) will be analysed and ranked by a global parameter, calculated by applying the AHP methodology. The main target of the work is to find an adequate SMR system to power a ship. Top designs will be described in detail, and conclusions will be drawn from the results. This project has been conceived as an effort to foster the near-term development of zero-emission maritime traffic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=international%20shipping" title="international shipping">international shipping</a>, <a href="https://publications.waset.org/abstracts/search?q=decarbonization" title=" decarbonization"> decarbonization</a>, <a href="https://publications.waset.org/abstracts/search?q=SMR" title=" SMR"> SMR</a>, <a href="https://publications.waset.org/abstracts/search?q=AHP" title=" AHP"> AHP</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear-fuelled%20vessels" title=" nuclear-fuelled vessels"> nuclear-fuelled vessels</a> </p> <a href="https://publications.waset.org/abstracts/152491/appliance-of-the-analytic-hierarchy-process-methodology-for-the-selection-of-a-small-modular-reactors-to-enhance-maritime-traffic-decarbonisation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152491.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">125</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">527</span> Scaling out Sustainable Land Use Systems in Colombia: Some Insights and Implications from Two Regional Case Studies </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martha%20Lilia%20Del%20Rio%20Duque">Martha Lilia Del Rio Duque</a>, <a href="https://publications.waset.org/abstracts/search?q=Michelle%20Bonatti"> Michelle Bonatti</a>, <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Loehr"> Katharina Loehr</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcos%20Lana"> Marcos Lana</a>, <a href="https://publications.waset.org/abstracts/search?q=Tatiana%20Rodriguez"> Tatiana Rodriguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefan%20Sieber"> Stefan Sieber</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, most agricultural practices can reduce the ability of ecosystems to provide goods and services. To enhance environmentally friendly food production and to maximize social and economic benefits, sustainable land use systems (SLUS) are one of the most critical strategies increasingly/strongly promoted by donors organizations, international agencies, and policymakers. This process involves the question of how SLUS can be scaled out also large-scale landscapes and not merely isolated experiments. As SLUS are context-specific strategies, diffusion and replication of successful SLUS in Colombia required the identification of main factors that facilitate this scaling out process. We applied a case study approach to investigate the scaling out process of SLUS in cocoa and livestock sector within peacebuilding territories in Colombia, specifically, in Cesar and Caqueta region. These two regions are contrasting, but both have a current trend of increasing land degradation. Presently in Colombia, Caqueta is one of the most deforested departments, and Cesar has some most degraded soils. Following a qualitative research approach, 19 semi-structured interviews and 2 focus groups were conducted with agroforestry experts in both regions to analyze (1) what does it mean a sustainable land use system in Cocoa/Livestock, specifically in Caqueta or Cesar and (2) to identify the key elements at the level of the following dimensions: biophysical, economic and profitability, market, social, policy and institutions that can explain how and why SLUS are replicated and spread among more producers. The Interviews were coded and analyzed using MAXQDA to identify, analyze and report patterns (themes) within data. As the results show, key themes, among which: premium market, solid regional markets and price stability, water availability and management, generational renewal, land use knowledge and diversification, producer organization and certifications are crucial to understand how the SLUS can have an impact across large-scale landscapes and how the scaling out process can be set up best in order to be successful across different contexts. The analysis further reveals which key factors might affect SLUS efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agroforestry" title="agroforestry">agroforestry</a>, <a href="https://publications.waset.org/abstracts/search?q=cocoa%20sector" title=" cocoa sector"> cocoa sector</a>, <a href="https://publications.waset.org/abstracts/search?q=Colombia" title=" Colombia"> Colombia</a>, <a href="https://publications.waset.org/abstracts/search?q=livestock%20sector" title=" livestock sector"> livestock sector</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20land%20use%20system" title=" sustainable land use system"> sustainable land use system</a> </p> <a href="https://publications.waset.org/abstracts/129873/scaling-out-sustainable-land-use-systems-in-colombia-some-insights-and-implications-from-two-regional-case-studies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129873.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">160</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">526</span> Model of the Increasing the Capacity of the Train and Railway Track by Using the New Type of Wagon</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martin%20Kendra">Martin Kendra</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaroslav%20Ma%C5%A1ek"> Jaroslav Mašek</a>, <a href="https://publications.waset.org/abstracts/search?q=Juraj%20%C4%8Camaj"> Juraj Čamaj</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20B%C3%BAda"> Martin Búda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper deals with possibilities of increase train capacity by using a new type of railway wagon.

Located in Lake Superior, it has been home to the Anishinaabe/Ojibway people for 1000s of years and is known as Moningwankuaning Minis-"The Island of the Golden Breasted Woodpecker". The community relies on summer tourism as its source of income, with a small population of 400 year-round residents. Supervisor Martin A. Curry (Ojibway/German descent) has been working on a fiscally responsible, environmentally principled and culturally centered approach to waste diversion and recycling. The tenets of this program encompass plastics, paper, food waste, local farming, energy production and art education. Through creative writing for the local newspaper and creative interactions, Martin has worked to engage the community in a more robust interest in waste diversion, including setting up a free-will donation store that incorporates elder volunteering opportunities, a compost program that works with the local community garden, biodiesel production and an art program that works with children from the local island school to make paper, grow local food and paint murals. The entirety of this program is based on the Ojibway concept of Mino-Bimadiiziwiin- "The Good Life" and benefits the community and its guests and represents a microcosm of the global dilemmas of waste and recycling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=recycling" title="recycling">recycling</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20diversion" title=" waste diversion"> waste diversion</a>, <a href="https://publications.waset.org/abstracts/search?q=island" title=" island"> island</a>, <a href="https://publications.waset.org/abstracts/search?q=Native%20American" title=" Native American"> Native American</a>, <a href="https://publications.waset.org/abstracts/search?q=art" title=" art"> art</a> </p> <a href="https://publications.waset.org/abstracts/166066/the-cultural-significance-of-recycling-a-native-american-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166066.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">116</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">524</span> Enframing the Smart City: Utilizing Heidegger's 'The Question Concerning Technology' as a Framework to Interpret Smart Urbanism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Will%20Brown">Will Brown</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Martin Heidegger is considered to be one of the leading philosophical lights of the 20th century with his lecture/essay 'The Question Concerning Technology' proving to be an invaluable text in the study of technology and the understanding of how technology influences the world it is set upon. However, this text has not as of yet been applied to the rapid rise and proliferation of ‘smart’ cities. This article is premised upon the application of the aforementioned text and the smart city in order to provide a fresh, if not critical analysis and interpretation of this phenomena. The first section below provides a brief literature review of smart urbanism in order to lay the groundwork necessary to apply Heidegger’s work to the smart city, from which a framework is developed to interpret the infusion of digital sensing technologies and the urban milieu. This framework is comprised of four concepts put forward in Heidegger’s text: circumscribing, bringing-forth, challenging, and standing-reserve. A concluding chapter is based upon the notion of enframement, arguing that once the rubric of data collection is placed within the urban system, future systems will require the capability to harvest data, resulting in an ever-renewing smart city. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20quality%20sensing" title="air quality sensing">air quality sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=big%20data" title=" big data"> big data</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Heidegger" title=" Martin Heidegger"> Martin Heidegger</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20city" title=" smart city"> smart city</a> </p> <a href="https://publications.waset.org/abstracts/110342/enframing-the-smart-city-utilizing-heideggers-the-question-concerning-technology-as-a-framework-to-interpret-smart-urbanism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110342.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">208</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">523</span> Educase–Intelligent System for Pedagogical Advising Using Case-Based Reasoning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elionai%20Moura">Elionai Moura</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20A.%20Cunha"> José A.

The only possibility how to make their simultaneous improvement is to provide the microstructural refinement, by cold deformation, and subsequent recrystallization. However, application of this kind of treatment is impossible for high-carbon high-alloyed ledeburitic tool steels. Alternatively, it has been demonstrated over the last few years that sub-zero treatment induces some microstructural changes in these materials, which might favourably influence their complex of mechanical properties. Commercially available PM ledeburitic steel Vanadis 6 has been used for the current investigations. The paper demonstrates that sub-zero treatment induces clear refinement of the martensite, reduces the amount of retained austenite, enhances the population density of fine carbides, and makes alterations in microstructural development that take place during tempering. As a consequence, the steel manifests improved wear resistance at higher toughness and fracture toughness. Based on the obtained results, the key question “can the wear performance be improved by sub-zero treatment simultaneously with toughness” can be answered by “definitely yes”. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ledeburitic%20tool%20steels" title="ledeburitic tool steels">ledeburitic tool steels</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=sub-zero%20treatment" title=" sub-zero treatment"> sub-zero treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a> </p> <a href="https://publications.waset.org/abstracts/81060/simultaneous-improvement-of-wear-performance-and-toughness-of-ledeburitic-tool-steels-by-sub-zero-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81060.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">318</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">521</span> Design and Study of a DC/DC Converter for High Power, 14.4 V and 300 A for Automotive Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J%C3%BAlio%20Cesar%20Lopes%20de%20Oliveira">Júlio Cesar Lopes de Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Henrique%20Gon%C3%A7alves%20Treviso"> Carlos Henrique Gonçalves Treviso</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The shortage of the automotive market in relation to options for sources of high power car audio systems, led to development of this work.

The role of domestic regional differences and the relationship with asymmetries within a country are usually left out. This paper looks at the asymmetry in the transmission of rice prices from the international price to the farm gate prices in four northern regions of Peru for the last period 2001-2016. These regions are San Martín, Piura, Lambayeque and La Libertad. The relevance of the study lies in its ability to assess the need for policies aimed at improving the competitiveness of the market and ensuring the benefit of producers. There are differences in planting and harvesting dates, as well as in geographic location that justify the hypothesis of the existence of differences in the price transition asymmetries between these regions. Those differences are due to at least three factors geography, infrastructure development, and distribution systems. For this, the Threshold Vector Error Correction Model and the Autoregressive Vector Model with Threshold are used. Both models, collect asymmetric effects in the price adjustments. In this way, it is sought to verify that farm prices react more to falls than increases in international prices due to the high bargaining power of intermediaries. The results of the investigation suggest that the transmission of prices is significant only for Lambayeque and La Libertad. Likewise, the asymmetry in the transmission of prices for these regions is checked. However, these results are not met for San Martin and Piura, the main rice producers nationwide. A significant price transmission is verified only in the Lambayeque and La Libertad regions. San Martin and Piura, in spite of being the main rice producing regions of Peru, do not present a significant transmission of international prices; a high degree of self-sufficient supply might be at the center of the logic for this result. An additional finding is the short-term adjustment with respect to international prices, it is higher in La Libertad compared to Lambayeque, which could be explained by the greater bargaining power of intermediaries in the last-mentioned region due to the greater technological development in the mills. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20price%20transmission" title="asymmetric price transmission">asymmetric price transmission</a>, <a href="https://publications.waset.org/abstracts/search?q=rice%20prices" title=" rice prices"> rice prices</a>, <a href="https://publications.waset.org/abstracts/search?q=price%20transmission" title=" price transmission"> price transmission</a>, <a href="https://publications.waset.org/abstracts/search?q=regional%20economics" title=" regional economics"> regional economics</a> </p> <a href="https://publications.waset.org/abstracts/90175/asymmetric-price-transmission-in-rice-a-regional-analysis-in-peru" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90175.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">227</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">519</span> Undocumented Migrants on the Northern Border of Mexico: Social Imaginary, and Social Representations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C%C3%A9sar%20Enrique%20Jim%C3%A9nez%20Ya%C3%B1ez">César Enrique Jiménez Yañez</a>, <a href="https://publications.waset.org/abstracts/search?q=Yessica%20Martinez%20Soto"> Yessica Martinez Soto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present work, the phenomenon of undocumented migration in the northern border of Mexico is analyzed through the graphic representation of the experience of people who migrate in an undocumented way to the United States. 33 of them drew what it meant for them to migrate.

The interaction between phytoplankton and zooplankton population is considered to be Crowley-Martin type functional response. It has been assumed that phytoplankton grows logistically and is affected by a space-dependent growth rate. Conditions for the existence of a positive equilibrium point and their stability analysis (both local and global) have been discussed for the non-spatial system. We have discussed maximum sustainable yields as well as optimal harvesting policy for maximizing the economic gain. The stability and existence of Hopf –bifurcation analysis have been discussed for the spatial system. Different conditions for turning pattern formation have been established through diffusion-driven instability analysis. Numerical simulations have been carried out for both non-spatial and spatial models. Phase plane analysis, the largest Lyapunov exponent, and bifurcation theory are used to numerically analyzed the non-spatial system. Our study shows that spatial heterogeneity, the mortality rate of phytoplankton, and constant harvesting of the fish population each play an important role in the dynamical behavior of the marine system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optimal%20harvesting" title="optimal harvesting">optimal harvesting</a>, <a href="https://publications.waset.org/abstracts/search?q=pattern%20formation" title=" pattern formation"> pattern formation</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20heterogeneity" title=" spatial heterogeneity"> spatial heterogeneity</a>, <a href="https://publications.waset.org/abstracts/search?q=Crowley-Martin%20functional%20response" title=" Crowley-Martin functional response"> Crowley-Martin functional response</a> </p> <a href="https://publications.waset.org/abstracts/116579/population-dynamics-in-aquatic-environments-spatial-heterogeneity-and-optimal-harvesting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116579.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">517</span> Resilence and Adaptation to Water Scarcity in San Martín de las Palmas, Santiago Tilantongo, Nochixtlán Oaxaca</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Montesinos-Pedro">E.

The Municipality of Santiago Tilantongo belongs to the district of Nochixtlán Oaxaca, it’s built up from 14 communities, one of them San Martin de las Palmas. This community was founded in 1900, at that time the inhabitants were supplied with water through rivers of the region which were abundant (they used containers filled in the river for that purpose); However, over the years the level of the rivers began to drop and in 1994 specific wells were located to store water and at the same time make it drinkable, this whit support of the state of Oaxaca and the program Procampo. By the year 2000 the shortage of water in the supply sources was notorious, the community requested support from the Oaxaca State government to solve the problem. The government’s response consisted in the implementation of ferro-cement tanks (2005) and water wells (2010), both for rainwater collection, Hower, it was not enough. Now days the community has a population of 60 inhabitants who have resisted and adapted to water scarcity, not only with the programs implemented by the government, but they also have implemented important structural analysis strategies. The objective of this research is to know the adaptation strategies used by the community to analyze them and propose improvements for water conservation and mitigation of this scarcity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptation" title="adaptation">adaptation</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=mitigation" title=" mitigation"> mitigation</a>, <a href="https://publications.waset.org/abstracts/search?q=resiliencia" title=" resiliencia"> resiliencia</a> </p> <a href="https://publications.waset.org/abstracts/162697/resilence-and-adaptation-to-water-scarcity-in-san-martin-de-las-palmas-santiago-tilantongo-nochixtlan-oaxaca" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162697.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">97</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">516</span> Flow Visualization in Biological Complex Geometries for Personalized Medicine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Escobar-del%20Pozo">Carlos Escobar-del Pozo</a>, <a href="https://publications.waset.org/abstracts/search?q=C%C3%A9sar%20Ahumada-Monroy"> César Ahumada-Monroy</a>, <a href="https://publications.waset.org/abstracts/search?q=Azael%20Garc%C3%ADa-Rebolledo"> Azael García-Rebolledo</a>, <a href="https://publications.waset.org/abstracts/search?q=Alberto%20Brambila-Sol%C3%B3rzano"> Alberto Brambila-Solórzano</a>, <a href="https://publications.waset.org/abstracts/search?q=Gregorio%20Mart%C3%ADnez-S%C3%A1nchez"> Gregorio Martínez-Sánchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Ortiz-Rinc%C3%B3n"> Luis Ortiz-Rincón</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Numerical simulations of flow in complex biological structures have gained considerable attention in the last years.

Also, network synchronization is evaluated according to a particular coupling strength for each topology.

Through a comprehensive literature review, we found consistent evidence supporting the positive influence of Transcendental Mindfulness Meditation on reducing anxiety, enhancing overall well-being, and decreasing perceived stress levels within this demographic. The mechanisms underlying these effects include heightened self-awareness, improved emotional regulation, and the development of effective stress-coping strategies. These findings have significant implications for mental health interventions targeting young females. However, the reviewed studies had some limitations, such as small sample sizes and reliance on self-report measures. To advance this field, future research should focus on larger sample sizes and utilize a broader range of measurement methods, including neuroscience assessments. Additionally, investigating the temporal relationships between Transcendental Mindfulness Meditation, proposed mediators, and anxiety symptoms will help establish causal specificity and a deeper understanding of the precise mechanisms of action. The development of integrative models based on these mechanisms can further enhance the effectiveness of Transcendental Mindfulness Meditation as an intervention for anxiety in this demographic. This study contributes to the current knowledge on the potential benefits of Transcendental Mindfulness Meditation for reducing anxiety in young females, paving the way for more targeted and effective mental health interventions in this population. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mindfulness" title="mindfulness">mindfulness</a>, <a href="https://publications.waset.org/abstracts/search?q=meditation" title=" meditation"> meditation</a>, <a href="https://publications.waset.org/abstracts/search?q=anxiety" title=" anxiety"> anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=transcendental%20mindfulness" title=" transcendental mindfulness"> transcendental mindfulness</a> </p> <a href="https://publications.waset.org/abstracts/175852/exploring-the-effects-of-transcendental-mindfulness-meditation-on-anxiety-symptoms-in-young-females" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175852.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">70</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">509</span> Relation of Electromyography, Strength and Fatigue During Ramp Isometric Contractions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cesar%20Ferreira%20Amorim">Cesar Ferreira Amorim</a>, <a href="https://publications.waset.org/abstracts/search?q=Tamotsu%20Hirata"> Tamotsu Hirata</a>, <a href="https://publications.waset.org/abstracts/search?q=Runer%20Augusto%20Marson"> Runer Augusto Marson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study was to determine the effect of strength ramp isometric contraction on changes in surface electromyography (sEMG) signal characteristics of the hamstrings muscles. All measurements were obtained from 20 healthy well trained healthy adults (age 19.5 ± 0.8 yrs, body mass 63.4 ± 1.5 kg, height: 1.65 ± 0.05 m). Subjects had to perform isometric ramp contractions in knee flexion with the force gradually increasing from 0 to 40% of the maximal voluntary contraction (MVC) in a 20s period. The root mean square (RMS) amplitude of sEMG signals obtained from the biceps femoris (caput longum) were calculated at four different strength levels (10, 20, 30, and 40% MVC) from the ramp isometric contractions (5s during the 20s task %MVC). The main results were a more pronounced increase non-linear in sEMG-RMS amplitude for the muscles.

We present here the task of learning centers of mass with an extra feature that “activates” some of the coordinates over the unit ball in a Hilbert space. We show that the learning problem is learnable under a stable RLM rule. We introduce a family of distributions over the domain space with some mild restrictions for which the sample complexity of uniform convergence for these problems must grow logarithmically with the dimension of the Hilbert space. If we take this dimension to infinity, we obtain a learnable problem for which the uniform convergence property fails for a vast family of distributions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=statistical%20learning%20theory" title="statistical learning theory">statistical learning theory</a>, <a href="https://publications.waset.org/abstracts/search?q=learnability" title=" learnability"> learnability</a>, <a href="https://publications.waset.org/abstracts/search?q=uniform%20convergence" title=" uniform convergence"> uniform convergence</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a>, <a href="https://publications.waset.org/abstracts/search?q=regularized%20loss%20minimization" title=" regularized loss minimization"> regularized loss minimization</a> </p> <a href="https://publications.waset.org/abstracts/151038/a-family-of-distributions-on-learnable-problems-without-uniform-convergence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151038.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">129</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">506</span> Collective Movement between Two Lego EV3 Mobile Robots</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luis%20Fernando%20Pinedo-Lomeli">Luis Fernando Pinedo-Lomeli</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosa%20Martha%20Lopez-Gutierrez"> Rosa Martha Lopez-Gutierrez</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Antonio%20Michel-Macarty"> Jose Antonio Michel-Macarty</a>, <a href="https://publications.waset.org/abstracts/search?q=Cesar%20Cruz-Hernandez"> Cesar Cruz-Hernandez</a>, <a href="https://publications.waset.org/abstracts/search?q=Liliana%20Cardoza-Avenda%C3%B1o"> Liliana Cardoza-Avendaño</a>, <a href="https://publications.waset.org/abstracts/search?q=Humberto%20Cruz-Hernandez"> Humberto Cruz-Hernandez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Robots are working in industry and services performing repetitive or dangerous tasks, however, when flexible movement capabilities and complex tasks are required, the use of many robots is needed. Also, productivity can be improved by reducing times to perform tasks. In the last years, a lot of effort has been invested in research and development of collective control of mobile robots. This interest is justified as there are many advantages when two or more robots are collaborating in a particular task. Some examples are: cleaning toxic waste, transportation and manipulation of objects, exploration, and surveillance, search and rescue. In this work a study of collective movements of mobile robots is presented. A solution of collisions avoidance is developed. This solution is levered on a communication implementation that allows coordinate movements in different paths were avoiding obstacles. <p class="card-text"><strong>Keywords:</strong> <a
