In the last decades, we find different kinds of approaches in the discipline of Architecture and Urbanism based in the so-called Sciences of Complexity. In this context, this paper uses mathematics from the Network Theory. Hence, it proposes a methodology based in obtaining information from a graph, which is created from a network of urban streets. Then, it is used an algorithm that establishes a ranking of importance of the nodes of that network, from its topological point of view. The results are applied to a heritage area in a particular city, confronting the data obtained from the mathematical model, with the ones from the field work in the case study. As a result of this process, we may conclude the necessity of implementing some actions in the area, and where those actions would be more effective for the whole heritage site. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=graphs" title="graphs">graphs</a>, <a href="https://publications.waset.org/abstracts/search?q=heritage%20cities" title=" heritage cities"> heritage cities</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20analysis" title=" spatial analysis"> spatial analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20networks" title=" urban networks"> urban networks</a> </p> <a href="https://publications.waset.org/abstracts/67220/a-topological-study-of-an-urban-street-network-and-its-use-in-heritage-areas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67220.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">396</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">595</span> Visualizing the Commercial Activity of a City by Analyzing the Data Information in Layers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Taras%20Agryzkov">Taras Agryzkov</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20L.%20Oliver"> Jose L.

As it is well known, the Theory of Architecture and Urbanism has been using for decades’ intellectual tools based on the ‘sciences of complexity’ as a strategy to propose theoretical approaches about cities and about architecture. In this sense, it is possible to find a vast literature in which for instance network theory is used as an instrument to understand very diverse questions about cities: from their commercial activity to their heritage condition. The contribution of this research consists in adding one step of complexity to this process: instead of working with one single primal graph as it is usually done, we will show how new network models arise from the consideration of two different primal graphs interacting in two layers. When we model an urban network through a mathematical structure like a graph, the city is usually represented by a set of nodes and edges that reproduce its topology, with the data generated or extracted from the city embedded in it. All this information is normally displayed in a single layer. Here, we propose to separate the information in two layers so that we can evaluate the interaction between them. Besides, both layers may be composed of structures that do not have to coincide: from this bi-layer system, groups of interactions emerge, suggesting reflections and in consequence, possible actions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=graphs" title="graphs">graphs</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematics" title=" mathematics"> mathematics</a>, <a href="https://publications.waset.org/abstracts/search?q=networks" title=" networks"> networks</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20studies" title=" urban studies"> urban studies</a> </p> <a href="https://publications.waset.org/abstracts/97085/visualizing-the-commercial-activity-of-a-city-by-analyzing-the-data-information-in-layers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97085.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">180</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">594</span> Urban Networks as Model of Sustainable Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agryzkov%20Taras">Agryzkov Taras</a>, <a href="https://publications.waset.org/abstracts/search?q=Oliver%20Jose%20L."> Oliver Jose L.</a>, <a href="https://publications.waset.org/abstracts/search?q=Tortosa%20Leandro"> Tortosa Leandro</a>, <a href="https://publications.waset.org/abstracts/search?q=Vicent%20Jose"> Vicent Jose </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to demonstrate how the consideration of cities as a special kind of complex network, called urban network, may lead to the use of design tools coming from network theories which, in fact, results in a quite sustainable approach. There is no doubt that the irruption in contemporary thought of Gaia as an essential political agent proposes a narrative that has been extended to the field of creative processes in which, of course, the activity of Urban Design is found. The rationalist paradigm is put in crisis, and from the so-called sciences of complexity, its way of describing reality and of intervening in it is questioned. Thus, a new way of understanding reality surges, which has to do with a redefinition of the human being's own place in what is now understood as a delicate and complex network. In this sense, we know that in these systems of connected and interdependent elements, the influences generated by them originate emergent properties and behaviors for the whole that, individually studied, would not make sense. We believe that the design of cities cannot remain oblivious to these principles, and therefore this research aims to demonstrate the potential that they have for decision-making in the urban environment. Thus, we will see an example of action in the field of public mobility, another example in the design of commercial areas, and a third example in the field of redensification of sprawl areas, in which different aspects of network theory have been applied to change the urban design. We think that even though these actions have been developed in European cities, and more specifically in the Mediterranean area in Spain, the reflections and tools could have a broader scope of action. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=graphs" title="graphs">graphs</a>, <a href="https://publications.waset.org/abstracts/search?q=complexity%20sciences" title=" complexity sciences"> complexity sciences</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20networks" title=" urban networks"> urban networks</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20design" title=" urban design"> urban design</a> </p> <a href="https://publications.waset.org/abstracts/133799/urban-networks-as-model-of-sustainable-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133799.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">154</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">593</span> Digitalization in Aggregate Quarries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Eugenio%20Ortiz">José Eugenio Ortiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Pierre%20Plaza"> Pierre Plaza</a>, <a href="https://publications.waset.org/abstracts/search?q=Josefa%20Herrero"> Josefa Herrero</a>, <a href="https://publications.waset.org/abstracts/search?q=Iv%C3%A1n%20Cabria"> Iván Cabria</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Luis%20Blanco"> José Luis Blanco</a>, <a href="https://publications.waset.org/abstracts/search?q=Javier%20Gavilanes"> Javier Gavilanes</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Ignacio%20Escavy"> José Ignacio Escavy</a>, <a href="https://publications.waset.org/abstracts/search?q=Ignacio%20L%C3%B3pez-Cilla"> Ignacio López-Cilla</a>, <a href="https://publications.waset.org/abstracts/search?q=Virginia%20Yag%C3%BCe"> Virginia Yagüe</a>, <a href="https://publications.waset.org/abstracts/search?q=C%C3%A9sar%20P%C3%A9rez"> César Pérez</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Rodr%C3%ADguez"> Silvia Rodríguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Rico"> Jorge Rico</a>, <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Serrano"> Cecilia Serrano</a>, <a href="https://publications.waset.org/abstracts/search?q=Jes%C3%BAs%20Bernat"> Jesús Bernat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of Artificial Intelligence services in mining processes, specifically in aggregate quarries, is facilitating automation and improving numerous aspects of operations.

We aim to explain in this work what are the most relevant ones and how this phenomenon is modeled from both optics and electromagnetics points of view. We also explain here how the amplitude of an electromagnetic wave reflected by a lossy conductor could depend on both the frequency of the incident wave, as well as on the electrical properties of the conductor, and we illustrate this phenomenon with a practical example. The mathematical analysis made by a specialist in electromagnetics or a microwave engineer is apparently very different from the one made by a specialist in optics. We show here how both approaches lead to the same physical result and what are the key concepts which enable one to understand that despite the differences in the equations the solution to the problem happens to be the same. Our study starts with an analysis made by using the complex refractive index and the reflectance parameter. We show how this reflectance has a dependence with the square root of the frequency when the reflecting material is a good conductor, and the frequency of the wave is low enough. Then we analyze the same problem with a less known approach, which is based on the reflection coefficient of the electric field, a parameter that is most commonly used in electromagnetics and microwave engineering. In summary, this paper presents a mathematical study illustrated with a worked example which unifies the modeling of dispersion effects made by specialists in optics and the one made by specialists in electromagnetics. The main finding of this work is that it is possible to reproduce the dependence of the Fresnel reflectance with frequency from the intrinsic impedance of the reflecting media. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dispersion" title="dispersion">dispersion</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20waves" title=" electromagnetic waves"> electromagnetic waves</a>, <a href="https://publications.waset.org/abstracts/search?q=microwaves" title=" microwaves"> microwaves</a>, <a href="https://publications.waset.org/abstracts/search?q=optics" title=" optics"> optics</a> </p> <a href="https://publications.waset.org/abstracts/107650/dispersion-effects-in-waves-reflected-by-lossy-conductors-the-optics-vs-electromagnetics-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107650.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">591</span> The Science of Dreaming and Sleep in Selected Charles Dickens' Novels and Letters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olga%20Colbert">Olga Colbert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present work examines the representation of dreaming in Charles Dickens’ novels, particularly Oliver Twist. Dickens showed great interest in the science of dreaming and had ample knowledge of the latest dream theories in the Victorian era, as can be seen in his personal correspondence, most notably in his famous letter to Dr. Thomas Stone on 2/2/1851. This essay places Dickens’ personal writings side by side with his novels to elucidate whether the scientific paradigm about dreaming included in the novel is consistent with the current (in Dickens’ time) scientific knowledge, or whether it is anachronistic or visionary (ahead of his time). Oliver Twist is particularly useful because it contains entire passages pondering on the nature of dreaming, enumerating types of common dreams, and taking a stand on the interference of sensory perception during the dreaming state. The author is particularly intrigued by Dickens’ assumption of the commonality and universality of lucid dreaming as revealed in these passages. This essay places popular Victorian dream theories, such as those contained in Robert Macnish’s The Philosophy of Sleep, side by side with recent dream theory, particularly psychophysiologist Stephen LaBerge’s numerous articles and books on the topic of lucid dreaming to see if Dickens deviated in any way from the reigning paradigm of the Victorian era in his representation of dreaming in his novels. While Dickens puts to great narrative use many of the characteristics of dreaming described by leading Victorian theorists, the author of this study argues, however, that Dickens’ most visionary statements derive from his acute observations of his own dreaming experiences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=consciousness" title="consciousness">consciousness</a>, <a href="https://publications.waset.org/abstracts/search?q=Dickens" title=" Dickens"> Dickens</a>, <a href="https://publications.waset.org/abstracts/search?q=dreaming" title=" dreaming"> dreaming</a>, <a href="https://publications.waset.org/abstracts/search?q=lucid%20dreaming" title=" lucid dreaming"> lucid dreaming</a>, <a href="https://publications.waset.org/abstracts/search?q=Victorian" title=" Victorian"> Victorian</a> </p> <a href="https://publications.waset.org/abstracts/70169/the-science-of-dreaming-and-sleep-in-selected-charles-dickens-novels-and-letters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70169.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">289</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">590</span> Molecular Characterization and Identification of C-Type Lectin in Red Palm Weevil, Rhynchophorus ferrugineus Oliver</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hafiza%20Javaria%20Ashraf">Hafiza Javaria Ashraf</a>, <a href="https://publications.waset.org/abstracts/search?q=Xinghong%20Wang"> Xinghong Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhanghong%20Shi"> Zhanghong Shi</a>, <a href="https://publications.waset.org/abstracts/search?q=Youming%20Hou"> Youming Hou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Insect’s innate immunity depends on a variety of defense responses for the recognition of invading pathogens. Pathogen recognition involves particular proteins known as pattern recognition receptors (PRRs). These PRRs interact with pathogen-associated molecular patterns (PAMPs) present on the surface of pathogens to distinguish between self and non-self. C-type lectins (CTLs) belong to a superfamily of PPRs which involved in insect immunity and defense mechanism. Rhynchophorus ferrugineus Olivier is a devastating pest of Palm cultivations in China. Although studies on R. ferrugineus immune mechanism and host defense have conducted, however, the role of CTL in immune responses of R. ferrugineus remains elusive. Here, we report RfCTL, which is a secreted protein containing a single-CRD domain. The open reading frame (ORF) of CTL is 226 bp, which encodes a putative protein of 168 amino acids. Transcript expression analysis revealed that RfCTL highly expressed in immune-related tissues, i.e., hemolymph and fat body. The abundance of RfCTL in the gut and fat body dramatically increased upon Staphylococcus aureus and Escherichia coli bacterial challenges, suggesting a role in defense against gram-positive and gram-negative bacterial infection. Taken together, we inferred that RfCTL might be involved in the immune defense of R. ferrugineus and established a solid foundation for future studies on R. ferrugineus CTL domain proteins for better understanding of insect immunity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biological%20invasion" title="biological invasion">biological invasion</a>, <a href="https://publications.waset.org/abstracts/search?q=c-type%20lectin" title=" c-type lectin"> c-type lectin</a>, <a href="https://publications.waset.org/abstracts/search?q=insect%20immunity" title=" insect immunity"> insect immunity</a>, <a href="https://publications.waset.org/abstracts/search?q=Rhynchophorus%20ferrugineus%20Oliver" title=" Rhynchophorus ferrugineus Oliver"> Rhynchophorus ferrugineus Oliver</a> </p> <a href="https://publications.waset.org/abstracts/118350/molecular-characterization-and-identification-of-c-type-lectin-in-red-palm-weevil-rhynchophorus-ferrugineus-oliver" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118350.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">157</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">589</span> The Importance of Mental Health Literacy: Interventions in a Psychiatry Service of Hospital José Joaquim Fernandes, Portugal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mariana%20Mangas">Mariana Mangas</a>, <a href="https://publications.waset.org/abstracts/search?q=Yaroslava%20Martins"> Yaroslava Martins</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Charraz"> Ana Charraz</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Matos%20Pires"> Ana Matos Pires</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Health literacy empowers people of knowledge, motivation and skills to access, understand, evaluate and mobilize information relating to health. Although the benefits of public knowledge of physical disease are widely accepted, knowledge about mental disorder has been compatibly neglected. Nowadays there is considerably evidence that literacy is of great importance for the promotion of health and prevention of mental illness. Objective: Disclosure the concept and importance of mental health literacy and introduce the literacy program of Psychiatry Service of Hospital José Joaquim Fernandes. Methodology: A search was conducted on PubMed, using keywords “literacy” and “mental health”. A description of mental health literacy interventions implemented on Psychiatry Service of Hospital José Joaquim Fernandes was performed, namely, psychoeducation programs for depression and bipolar disorder. Results and discussion: Health literacy enables patient to be able to actively participate in his treatment. The improving of mental health literacy can promote early identification of mental disorders, improve treatment results, increase the use of health services and allow the community to take action to achieve better mental health. Psychoeducation is very useful in improving the course of disease and in reducing the number of episodes and hospitalizations. Bipolar patients who received psychoeducation and pharmacotherapy have no relapses during the program and last year. Conclusion: Mental health literacy is not simply a matter of having knowledge, rather, it is knowledge linked to action which can benefit mental health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mental%20health" title="mental health">mental health</a>, <a href="https://publications.waset.org/abstracts/search?q=literacy" title=" literacy"> literacy</a>, <a href="https://publications.waset.org/abstracts/search?q=psychoeducation" title=" psychoeducation"> psychoeducation</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge" title=" knowledge"> knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=empowerment" title=" empowerment"> empowerment</a> </p> <a href="https://publications.waset.org/abstracts/58750/the-importance-of-mental-health-literacy-interventions-in-a-psychiatry-service-of-hospital-jose-joaquim-fernandes-portugal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58750.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">547</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">588</span> Approach Based on Fuzzy C-Means for Band Selection in Hyperspectral Images</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diego%20Saqui">Diego Saqui</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20H.%20Saito"> José H.

A problem in the use of these images is the high volume of data to be processed, stored and transferred. Dimensionality reduction techniques can be used to reduce the volume of data. In this paper, an approach to band selection based on clustering algorithms is presented. This approach allows to reduce the volume of data. The proposed structure is based on Fuzzy C-Means (or K-Means) and NWHFC algorithms. New attributes in relation to other studies in the literature, such as kurtosis and low correlation, are also considered. A comparison of the results of the approach using the Fuzzy C-Means and K-Means with different attributes is performed. The use of both algorithms show similar good results but, particularly when used attributes variance and kurtosis in the clustering process, however applicable in hyperspectral images. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=band%20selection" title="band selection">band selection</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20c-means" title=" fuzzy c-means"> fuzzy c-means</a>, <a href="https://publications.waset.org/abstracts/search?q=k-means" title=" k-means"> k-means</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperspectral%20image" title=" hyperspectral image"> hyperspectral image</a> </p> <a href="https://publications.waset.org/abstracts/50614/approach-based-on-fuzzy-c-means-for-band-selection-in-hyperspectral-images" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50614.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">407</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">587</span> Verification Protocols for the Lightning Protection of a Large Scale Scientific Instrument in Harsh Environments: A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Clara%20Oliver">Clara Oliver</a>, <a href="https://publications.waset.org/abstracts/search?q=Oibar%20Martinez"> Oibar Martinez</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Miguel%20Miranda"> Jose Miguel Miranda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is devoted to the study of the most suitable protocols to verify the lightning protection and ground resistance quality in a large-scale scientific facility located in a harsh environment. We illustrate this work by reviewing a case study: the largest telescopes of the Northern Hemisphere Cherenkov Telescope Array, CTA-N. This array hosts sensitive and high-speed optoelectronics instrumentation and sits on a clear, free from obstacle terrain at around 2400 m above sea level. The site offers a top-quality sky but also features challenging conditions for a lightning protection system: the terrain is volcanic and has resistivities well above 1 kOhm·m. In addition, the environment often exhibits humidities well below 5%. On the other hand, the high complexity of a Cherenkov telescope structure does not allow a straightforward application of lightning protection standards. CTA-N has been conceived as an array of fourteen Cherenkov Telescopes of two different sizes, which will be constructed in La Palma Island, Spain. Cherenkov Telescopes can provide valuable information on different astrophysical sources from the gamma rays reaching the Earth’s atmosphere. The largest telescopes of CTA are called LST’s, and the construction of the first one was finished in October 2018. The LST has a shape which resembles a large parabolic antenna, with a 23-meter reflective surface supported by a tubular structure made of carbon fibers and steel tubes. The reflective surface has 400 square meters and is made of an array of segmented mirrors that can be controlled individually by a subsystem of actuators. This surface collects and focuses the Cherenkov photons into the camera, where 1855 photo-sensors convert the light in electrical signals that can be processed by dedicated electronics. We describe here how the risk assessment of direct strike impacts was made and how down conductors and ground system were both tested. The verification protocols which should be applied for the commissioning and operation phases are then explained. We stress our attention on the ground resistance quality assessment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=grounding" title="grounding">grounding</a>, <a href="https://publications.waset.org/abstracts/search?q=large%20scale%20scientific%20instrument" title=" large scale scientific instrument"> large scale scientific instrument</a>, <a href="https://publications.waset.org/abstracts/search?q=lightning%20risk%20assessment" title=" lightning risk assessment"> lightning risk assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=lightning%20standards%20and%20safety" title=" lightning standards and safety"> lightning standards and safety</a> </p> <a href="https://publications.waset.org/abstracts/107897/verification-protocols-for-the-lightning-protection-of-a-large-scale-scientific-instrument-in-harsh-environments-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107897.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">123</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">586</span> The Use of Network Theory in Heritage Cities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20L.%20Oliver">J.

In this paper, we use the suburb of La Villaflora in the city of Quito, Ecuador as our case study. We first propose a system of indicators as a tool to characterize and quantify the historic value of a geographic area. Then, we apply these indicators to the suburb of La Villaflora and use Network Theory to understand and propose actions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=graphs" title="graphs">graphs</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematics" title=" mathematics"> mathematics</a>, <a href="https://publications.waset.org/abstracts/search?q=networks" title=" networks"> networks</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20studies" title=" urban studies"> urban studies</a> </p> <a href="https://publications.waset.org/abstracts/56099/the-use-of-network-theory-in-heritage-cities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56099.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">369</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">585</span> MEAL Project–Modifying Eating Attitudes and Actions through Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Oliver">E.

Technical change has contributed considerably to supply agricultural expansion in Brazil. This agricultural growth could be achieved by incorporating more land or capital. If capital is the main source of agricultural growth, it is possible to increase production per unit of land. The objective of this paper is to estimate: 1) total factor productivity (TFP), which is measured in terms of the rate of output per unit of input; and 2) the land-saving effect (LSE) that is the amount of land required in the case that yield rate is constant over time. According to this study, from 1990 to 2019, it appears that 87 percent of Brazilian agriculture product growth comes from the gains of productivity; the rest of 13 percent comes from input growth. In the same period, the total LSE was roughly 400 Mha, which corresponds to 47 percent of the national territory. These effects reflect the greater efficiency of using productive factors, whose technical change has allowed an increase in agricultural production based on productivity gains. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agriculture" title="agriculture">agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=land-saving%20effect" title=" land-saving effect"> land-saving effect</a>, <a href="https://publications.waset.org/abstracts/search?q=livestock" title=" livestock"> livestock</a>, <a href="https://publications.waset.org/abstracts/search?q=productivity" title=" productivity"> productivity</a> </p> <a href="https://publications.waset.org/abstracts/137802/farming-production-in-brazil-innovation-and-land-sparing-effect" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137802.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">231</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">583</span> Association of Dietary Intake with the Nutrition Knowledge, Food Label Use, and Food Preferences of Adults in San Jose del Monte City, Bulacan, Philippines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Barby%20Jennette%20A.%20Florano">Barby Jennette A.

The aim of this study was to investigate whether nutrition knowledge, food label use, and food preference are associated with the dietary intake in a sample of San Jose Del Monte City, Bulacan (SJDM) adults. A sample of 148 adults, with a mean age of 20 years, completed a validated questionnaire related to their demographic, dietary intake, nutrition knowledge, food label use and food preference. Data were analyzed using Pearson correlation and there was no association between dietary intake and nutrition knowledge. However, there were positive relationships between dietary intake and food label use (r=0.1276, p<0.10), and dietary intake and food preference (r=0.1070, p<0.10). SJDM adults who use food label and have extensive food preference had better diet quality. This finding magnifies the role of nutrition education as a potential tool in health campaigns to promote healthy eating patterns and reading food labels among students and adults. Results of this study can give information for the design of future nutrition education intervention studies to assess the efficacy of nutrition knowledge and food label use among a similar sample population. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dietary%20intake" title="dietary intake">dietary intake</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrition%20knowledge" title=" nutrition knowledge"> nutrition knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20preference" title=" food preference"> food preference</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20label%20use" title=" food label use"> food label use</a> </p> <a href="https://publications.waset.org/abstracts/175413/association-of-dietary-intake-with-the-nutrition-knowledge-food-label-use-and-food-preferences-of-adults-in-san-jose-del-monte-city-bulacan-philippines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175413.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">91</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">582</span> Ecosystem Services Assessment for Urban Nature-Based Solutions Implemented in the Public Space: Case Study of Alhambra Square in Bogotá, Colombia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diego%20S%C3%A1nchez">Diego Sánchez</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20M.%20Aguilar"> Sandra M.

Software agents are autonomous and the diversity of interests among different members living in the same society is a fact. In order to deal with this autonomy, these open systems use mechanisms of social control (norms) to ensure a desirable social order. This paper considers the following types of norms: (i) obligation — agents must accomplish a specific outcome; (ii) permission — agents may act in a particular way, and (iii) prohibition — agents must not act in a specific way. All of these characteristics mean to encourage the fulfillment of norms through rewards and to discourage norm violation by pointing out the punishments. Once the software agent decides that its priority is the satisfaction of its own desires and goals, each agent must evaluate the effects associated to the fulfillment of one or more norms before choosing which one should be fulfilled. The same applies when agents decide to violate a norm. This paper also introduces a framework for the development of MASs that provide support mechanisms to the agent’s decision-making, using norm-based reasoning. The applicability and validation of this approach is demonstrated applying a traffic intersection scenario. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BDI%20agent" title="BDI agent">BDI agent</a>, <a href="https://publications.waset.org/abstracts/search?q=BDI4JADE%20framework" title=" BDI4JADE framework"> BDI4JADE framework</a>, <a href="https://publications.waset.org/abstracts/search?q=multiagent%20systems" title=" multiagent systems"> multiagent systems</a>, <a href="https://publications.waset.org/abstracts/search?q=normative%20agents" title=" normative agents"> normative agents</a> </p> <a href="https://publications.waset.org/abstracts/85259/extending-bdi-multiagent-systems-with-agent-norms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85259.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">231</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">580</span> Static Charge Control Plan for High-Density Electronics Centers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Clara%20Oliver">Clara Oliver</a>, <a href="https://publications.waset.org/abstracts/search?q=Oibar%20Martinez"> Oibar Martinez</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Miguel%20Miranda"> Jose Miguel Miranda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ensuring a safe environment for sensitive electronics boards in places with high limitations in size poses two major difficulties: the control of charge accumulation in floating floors and the prevention of excess charge generation due to air cooling flows. In this paper, we discuss these mechanisms and possible solutions to prevent them. An experiment was made in the control room of a Cherenkov Telescope, where six racks of 2x1x1 m size and independent cooling units are located. The room is 10x4x2.5 m, and the electronics include high-speed digitizers, trigger circuits, etc. The floor used in this room was antistatic, but it was a raised floor mounted in floating design to facilitate the handling of the cables and maintenance. The tests were made by measuring the contact voltage acquired by a person who was walking along the room with different footwear qualities. In addition, we took some measurements of the voltage accumulated in a person in other situations like running or sitting up and down on an office chair. The voltages were taken in real time with an electrostatic voltage meter and dedicated control software. It is shown that peak voltages as high as 5 kV were measured with ambient humidity of more than 30%, which are within the range of a class 3A according to the HBM standard. In order to complete the results, we have made the same experiment in different spaces with alternative types of the floor like synthetic floor and earthenware floor obtaining peak voltages much lower than the ones measured with the floating synthetic floor. The grounding quality one achieves with this kind of floors can hardly beat the one typically encountered in standard floors glued directly on a solid substrate. On the other hand, the air ventilation used to prevent the overheating of the boards probably contributed in a significant way to the charge accumulated in the room. During the assessment of the quality of the static charge control, it is necessary to guarantee that the tests are made under repeatable conditions. One of the major difficulties which one encounters during these assessments is the fact the electrostatic voltmeters might provide different values depending on the humidity conditions and ground resistance quality. In addition, the use of certified antistatic footwear might mask deficiencies in the charge control. In this paper, we show how we defined protocols to guarantee that electrostatic readings are reliable. We believe that this can be helpful not only to qualify the static charge control in a laboratory but also to asses any procedure oriented to minimize the risk of electrostatic discharge events. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrostatics" title="electrostatics">electrostatics</a>, <a href="https://publications.waset.org/abstracts/search?q=ESD%20protocols" title=" ESD protocols"> ESD protocols</a>, <a href="https://publications.waset.org/abstracts/search?q=HBM" title=" HBM"> HBM</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20charge%20control" title=" static charge control"> static charge control</a> </p> <a href="https://publications.waset.org/abstracts/107857/static-charge-control-plan-for-high-density-electronics-centers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107857.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">579</span> Road Traffic Accidents Analysis in Mexico City through Crowdsourcing Data and Data Mining Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gabriela%20V.%20Angeles%20Perez">Gabriela V.

Studies about traditional road traffic accidents in urban zones represents very high inversion of time and money, additionally, the result are not current. However, nowadays in many countries, the crowdsourced GPS based traffic and navigation apps have emerged as an important source of information to low cost to studies of road traffic accidents and urban congestion caused by them. In this article we identified the zones, roads and specific time in the CDMX in which the largest number of road traffic accidents are concentrated during 2016. We built a database compiling information obtained from the social network known as Waze. The methodology employed was Discovery of knowledge in the database (KDD) for the discovery of patterns in the accidents reports. Furthermore, using data mining techniques with the help of Weka. The selected algorithms was the Maximization of Expectations (EM) to obtain the number ideal of clusters for the data and k-means as a grouping method.

The reasons for this situation may be diverse, either they are not old enough, or they may show the modest architecture, the fact is these areas have not been considered deserving of protection, as the historical ones. As a result of this reality, they usually show now a very degraded urban space, which in addition contribute to accelerate a process of deterioration. Using a technic well known in urban design, we propose here a system of indicators for patrimonial purposes, as a tool to identify and quantify the heritage value of these kinds of areas.

By tracing the history and literature of surrealism, the author makes the argument that there were certain factions within Latin America that employed characteristics of surrealism in order to reach some sense of understanding, and not to further complicate or disorient -an aim that most closely aligns to Freudian psychoanalysis. Psychoanalysis should, however, be a comparable practice only to understand how Latin American surrealism had more of a concrete goal than its European counterpart. The primary subject of the paper is the Mexican poet, Pita Amor, who has retroactively been associated with the movement; and therefore, it should be duly noted that the adjective, surrealism, only applies to her as something that describes traits within the literary lexicon. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Latin%20America" title="Latin America">Latin America</a>, <a href="https://publications.waset.org/abstracts/search?q=Pita%20Amor" title=" Pita Amor"> Pita Amor</a>, <a href="https://publications.waset.org/abstracts/search?q=poetry" title=" poetry"> poetry</a>, <a href="https://publications.waset.org/abstracts/search?q=surrealism" title=" surrealism"> surrealism</a> </p> <a href="https://publications.waset.org/abstracts/115330/perception-and-control-in-the-age-of-surrealism-a-critical-history-and-a-survey-of-pita-amors-poetic-ontology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115330.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">144</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">576</span> Predicting the Product Life Cycle of Songs on Radio - How Record Labels Can Manage Product Portfolio and Prioritise Artists by Using Machine Learning Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Claus%20N.%20Holm">Claus N.

This paper develops a probabilistic methodology that predicts seismic loss for university buildings with simulated fragility functions. Two university buildings located in the city of Cusco were analyzed. Fragility functions were developed considering seismic and structural parameters uncertainty. The fragility functions were generated with the Latin Hypercube technique, an improved Montecarlo-based method, which optimizes the sampling of structural parameters and provides at least 100 reliable samples for every level of seismic demand. Concrete compressive strength, maximum concrete strain and yield stress of the reinforcing steel were considered as the key structural parameters. The seismic demand is defined by synthetic records which are compatible with the elastic Peruvian design spectrum. Acceleration records are scaled based on the peak ground acceleration on rigid soil (PGA) which goes from 0.05g to 1.00g. A total of 2000 structural models were considered to account for both structural and seismic variability. These functions represent the overall building behavior because they give rational information regarding damage ratios for defined levels of seismic demand. The university buildings show an expected Mean Damage Factor of 8.80% and 19.05%, respectively, for the 0.22g-PGA scenario, which was amplified by the soil type coefficient and resulted in 0.26g-PGA. These ratios were computed considering a seismic demand related to 10% of probability of exceedance in 50 years which is a requirement in the Peruvian seismic code. These results show an acceptable seismic performance for both buildings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fragility%20functions" title="fragility functions">fragility functions</a>, <a href="https://publications.waset.org/abstracts/search?q=university%20buildings" title=" university buildings"> university buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=loss%20assessment" title=" loss assessment"> loss assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=Montecarlo%20simulation" title=" Montecarlo simulation"> Montecarlo simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=latin%20hypercube" title=" latin hypercube"> latin hypercube</a> </p> <a href="https://publications.waset.org/abstracts/106519/seismic-loss-assessment-for-peruvian-university-buildings-with-simulated-fragility-functions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106519.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">144</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">570</span> The Impact of Bitcoin on Stock Market Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oliver%20Takawira">Oliver Takawira</a>, <a href="https://publications.waset.org/abstracts/search?q=Thembi%20Hope"> Thembi Hope</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study will analyse the relationship between Bitcoin price movements and the Johannesburg stock exchange (JSE). The aim is to determine whether Bitcoin price movements affect the stock market performance. As crypto currencies continue to gain prominence as a safe asset during periods of economic distress, this raises the question of whether Bitcoin’s prosperity could affect investment in the stock market. To identify the existence of a short run and long run linear relationship, the study will apply the Autoregressive Distributed Lag Model (ARDL) bounds test and a Vector Error Correction Model (VECM) after testing the data for unit roots and cointegration using the Augmented Dicker Fuller (ADF) and Phillips-Perron (PP). The Non-Linear Auto Regressive Distributed Lag (NARDL) will then be used to check if there is a non-linear relationship between bitcoin prices and stock market prices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bitcoin" title="bitcoin">bitcoin</a>, <a href="https://publications.waset.org/abstracts/search?q=stock%20market" title=" stock market"> stock market</a>, <a href="https://publications.waset.org/abstracts/search?q=interest%20rates" title=" interest rates"> interest rates</a>, <a href="https://publications.waset.org/abstracts/search?q=ARDL" title=" ARDL"> ARDL</a> </p> <a href="https://publications.waset.org/abstracts/150006/the-impact-of-bitcoin-on-stock-market-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150006.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">106</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">569</span> An Axisymmetric Finite Element Method for Compressible Swirling Flow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raphael%20Zanella">Raphael Zanella</a>, <a href="https://publications.waset.org/abstracts/search?q=Todd%20A.%20Oliver"> Todd A.

We are interested in problems where the flow, while weakly dependent on the azimuthal coordinate, may have a strong azimuthal velocity component. We describe the approximation of the compressible Navier-Stokes equations with H1-conformal spaces of axisymmetric functions. The weak formulation is implemented in a C++ solver with explicit time marching. The code is first verified with a convergence test on a manufactured solution. The verification is completed by comparing the numerical and analytical solutions in a Poiseuille flow case and a Taylor-Couette flow case. The code is finally applied to the problem of a swirling subsonic air flow in a plasma torch geometry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=axisymmetric%20problem" title="axisymmetric problem">axisymmetric problem</a>, <a href="https://publications.waset.org/abstracts/search?q=compressible%20Navier-Stokes%20equations" title=" compressible Navier-Stokes equations"> compressible Navier-Stokes equations</a>, <a href="https://publications.waset.org/abstracts/search?q=continuous%20finite%20elements" title=" continuous finite elements"> continuous finite elements</a>, <a href="https://publications.waset.org/abstracts/search?q=swirling%20flow" title=" swirling flow"> swirling flow</a> </p> <a href="https://publications.waset.org/abstracts/143638/an-axisymmetric-finite-element-method-for-compressible-swirling-flow" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143638.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">174</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">568</span> Strategies for the Optimization of Ground Resistance in Large Scale Foundations for Optimum Lightning Protection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oibar%20Martinez">Oibar Martinez</a>, <a href="https://publications.waset.org/abstracts/search?q=Clara%20Oliver"> Clara Oliver</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Miguel%20Miranda"> Jose Miguel Miranda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we discuss the standard improvements which can be made to reduce the earth resistance in difficult terrains for optimum lightning protection, what are the practical limitations, and how the modeling can be refined for accurate diagnostics and ground resistance minimization. Ground resistance minimization can be made via three different approaches: burying vertical electrodes connected in parallel, burying horizontal conductive plates or meshes, or modifying the own terrain, either by changing the entire terrain material in a large volume or by adding earth-enhancing compounds. The use of vertical electrodes connected in parallel pose several practical limitations. In order to prevent loss of effectiveness, it is necessary to keep a minimum distance between each electrode, which is typically around five times larger than the electrode length. Otherwise, the overlapping of the local equipotential lines around each electrode reduces the efficiency of the configuration. The addition of parallel electrodes reduces the resistance and facilitates the measurement, but the basic parallel resistor formula of circuit theory will always underestimate the final resistance. Numerical simulation of equipotential lines around the electrodes overcomes this limitation. The resistance of a single electrode will always be proportional to the soil resistivity. The electrodes are usually installed with a backfilling material of high conductivity, which increases the effective diameter. However, the improvement is marginal, since the electrode diameter counts in the estimation of the ground resistance via a logarithmic function. Substances that are used for efficient chemical treatment must be environmentally friendly and must feature stability, high hygroscopicity, low corrosivity, and high electrical conductivity. A number of earth enhancement materials are commercially available. Many are comprised of carbon-based materials or clays like bentonite. These materials can also be used as backfilling materials to reduce the resistance of an electrode. Chemical treatment of soil has environmental issues. Some products contain copper sulfate or other copper-based compounds, which may not be environmentally friendly. Carbon-based compounds are relatively inexpensive and they do have very low resistivities, but they also feature corrosion issues. Typically, the carbon can corrode and destroy a copper electrode in around five years. These compounds also have potential environmental concerns. Some earthing enhancement materials contain cement, which, after installation acquire properties that are very close to concrete. This prevents the earthing enhancement material from leaching into the soil. After analyzing different configurations, we conclude that a buried conductive ring with vertical electrodes connected periodically should be the optimum baseline solution for the grounding of a large size structure installed on a large resistivity terrain. In order to show this, a practical example is explained here where we simulate the ground resistance of a conductive ring buried in a terrain with a resistivity in the range of 1 kOhm·m. <p
