Significant system improvements are now seen particularly in multifunctional moveable concepts where the flight control functions are no longer considered separate but integral. This allows new functions to be implemented in order to improve the overall aircraft performance. However, the classical design process of flight controls is sequential and insufficiently interdisciplinary. In particular, the systems discipline is involved only rudimentarily in the early phase. In many cases, the task of systems design is limited to meeting the requirements of the upstream disciplines, which may lead to integration problems later. For this reason, approaching design with an incremental development is required to reduce the risk of a complete redesign. Although the potential and the path to multifunctional moveable concepts are shown, the complete re-engineering of aircraft concepts with less classic moveable concepts is associated with a considerable risk for the design due to the lack of design methods. This represents an obstacle to major leaps in technology. This gap in state of the art is even further increased if, in the future, unconventional aircraft configurations shall be considered, where no reference data or architectures are available. This means that the use of the above-mentioned experience-based approach used for conventional configurations is limited and not applicable to the next generation of aircraft. In particular, there is a need for methods and tools for a rapid trade-off between new multifunctional flight control systems architectures. To close this gap in the state of the art, an integrated system-driven design process for multifunctional flight control systems of non-classical aircraft configurations will be presented. The overall goal of the design process is to find optimal solutions for single or combined target criteria in a fast process from the very large solution space for the flight control system. In contrast to the state of the art, all disciplines are involved for a holistic design in an integrated rather than a sequential process. To emphasize the systems discipline, this paper focuses on the methodology for designing moveable actuation systems in the context of this integrated design process of multifunctional moveables. The methodology includes different approaches for creating system architectures, component design methods as well as the necessary process outputs to evaluate the systems. An application example of a reference configuration is used to demonstrate the process and validate the results. For this, new unconventional hydraulic and electrical flight control system architectures are calculated which result from the higher requirements for multifunctional moveable concept. In addition to typical key performance indicators such as mass and required power requirements, the results regarding the feasibility and wing integration aspects of the system components are examined and discussed here. This is intended to show how the systems design can influence and drive the wing and overall aircraft design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=actuation%20systems" title="actuation systems">actuation systems</a>, <a href="https://publications.waset.org/abstracts/search?q=flight%20control%20surfaces" title=" flight control surfaces"> flight control surfaces</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-functional%20movables" title=" multi-functional movables"> multi-functional movables</a>, <a href="https://publications.waset.org/abstracts/search?q=wing%20design%20process" title=" wing design process"> wing design process</a> </p> <a href="https://publications.waset.org/abstracts/97997/system-driven-design-process-for-integrated-multifunctional-movable-concepts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97997.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">81</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">80</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">79</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.

All three SPS types exhibit narrow emission lines (FWHM~0.35 - 2 meV) and high degrees of linear optical polarization (P > 70%) in the low-temperature micro-photoluminescence (µ-PL) experiments and are characterized by a pronounced antibunching in the photon correlation measurements (gcorrected(2)(0) < 0.3). The quantum-dot-like exciton localization centers induced by compositional fluctuations within the InGaN nanoshell are identified as the driving mechanism for the single photon emission. As confirmed by the low-temperature transmission electron microscopy combined with cathodoluminescence (TEM-CL) study, the crystal region (i.e. non-polar m-, semi-polar r- and polar c-facets) hosting the single photon emitters strongly affects their emission wavelength, which ranges from ultra-violet for the non-polar to visible for the polar SPSs. The photon emission lifetime is also found to be facet-dependent and varies from sub-nanosecond time scales for the non- and semi-polar SPSs to a few nanoseconds for the polar ones. These differences are mainly attributed to facet-dependent indium content and electric field distribution across the hosting InGaN nanoshell. The hereby reported pencil-like InGaN nanoshell is the first single nanostructure able to host all three types of single photon emitters and is thus a promising building block for tunable quantum light devices integrated into future photonic and optoelectronic circuits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GaN%20nanowire" title="GaN nanowire">GaN nanowire</a>, <a href="https://publications.waset.org/abstracts/search?q=InGaN%20nanoshell" title=" InGaN nanoshell"> InGaN nanoshell</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20polarization" title=" linear polarization"> linear polarization</a>, <a href="https://publications.waset.org/abstracts/search?q=nonpolar" title=" nonpolar"> nonpolar</a>, <a href="https://publications.waset.org/abstracts/search?q=semipolar" title=" semipolar"> semipolar</a>, <a href="https://publications.waset.org/abstracts/search?q=polar%20quantum%20dots" title=" polar quantum dots"> polar quantum dots</a>, <a href="https://publications.waset.org/abstracts/search?q=single-photon%20sources" title=" single-photon sources"> single-photon sources</a> </p> <a href="https://publications.waset.org/abstracts/69652/linearly-polarized-single-photon-emission-from-nonpolar-semipolar-and-polar-quantum-dots-in-ganingan-nanowires" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69652.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">392</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">76</span> The Use of Indicators to Evaluate Minor Heritage Areas in a City</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.

We mean by that those urban areas with high heritage interest from an academical point of view, but never properly valued. 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. As a case study, we apply this system in some part of the City of Quito (El Ecuador). <p class="card-text"><strong>Keywords:</strong> <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=indicators" title=" indicators"> indicators</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=historic%20sites" title=" historic sites "> historic sites </a> </p> <a href="https://publications.waset.org/abstracts/78809/the-use-of-indicators-to-evaluate-minor-heritage-areas-in-a-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78809.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">243</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">75</span> Perception and Control in the Age of Surrealism: A Critical History and a Survey of Pita Amor’s Poetic Ontology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oliver%20Arana">Oliver Arana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Within the common vein of social understanding, surrealism is often understood to rely on disconcerting images and fragmented collage, both in its visual representation and literary manifestations. 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">74</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.

Two types of particles are considered, with one of them being able to create connections to neighboring particles of the same type, thus forming a network within the agglomeration at the bottom of a cylinder.

These textile composites are advantageous due to their ease of manufacture, damage tolerance, and relatively low cost. However, physics-based modeling of the mechanical behavior of textile composites is challenging. Compared to their unidirectional counterparts, textile composites introduce additional geometric complexities, which cause significant local stress and strain concentrations. Since these internal concentrations are primary drivers of nonlinearity, damage, and failure within textile composites, they must be taken into account in order for the models to be predictive. The macro-scale approach to modeling textile-reinforced composites treats the whole composite as an effective, homogenized material. This approach is very computationally efficient, but it cannot be considered predictive beyond the elastic regime because the complex microstructural geometry is not considered. Further, this approach can, at best, offer a phenomenological treatment of nonlinear deformation and failure. In contrast, the mesoscale approach to modeling textile composites explicitly considers the internal geometry of the reinforcing tows, and thus, their interaction, and the effects of their curved paths can be modeled. The tows are treated as effective (homogenized) materials, requiring the use of anisotropic material models to capture their behavior. Finally, the micro-scale approach goes one level lower, modeling the individual filaments that constitute the tows. This paper will compare meso- and micro-scale approaches to modeling the deformation, damage, and failure of textile-reinforced polymer matrix composites. For the mesoscale approach, the woven composite architecture will be modeled using the finite element method, and an anisotropic damage model for the tows will be employed to capture the local nonlinear behavior. For the micro-scale, two different models will be used, the one being based on the finite element method, whereas the other one makes use of an embedded semi-analytical approach. The goal will be the comparison and evaluation of these approaches to modeling textile-reinforced composites in terms of accuracy, efficiency, and utility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multiscale%20modeling" title="multiscale modeling">multiscale modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=continuum%20damage%20model" title=" continuum damage model"> continuum damage model</a>, <a href="https://publications.waset.org/abstracts/search?q=damage%20interaction" title=" damage interaction"> damage interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=textile%20composites" title=" textile composites"> textile composites</a> </p> <a href="https://publications.waset.org/abstracts/32218/multiscale-modeling-of-damage-in-textile-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32218.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">354</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">70</span> Differential Antibrucella Activity of Bovine and Murine Macrophages</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raheela%20Akhtar">Raheela Akhtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Zafar%20Iqbal%20Chaudhary"> Zafar Iqbal Chaudhary</a>, <a href="https://publications.waset.org/abstracts/search?q=Yongqun%20Oliver%20He"> Yongqun Oliver He</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Younus"> Muhammad Younus</a>, <a href="https://publications.waset.org/abstracts/search?q=Aftab%20Ahmad%20Anjum"> Aftab Ahmad Anjum</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Brucella abortus is an intracellular pathogen affecting macrophages.

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">66</span> Neutral Heavy Scalar Searches via Standard Model Gauge Boson Decays at the Large Hadron Electron Collider with Multivariate Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luigi%20Delle%20Rose">Luigi Delle Rose</a>, <a href="https://publications.waset.org/abstracts/search?q=Oliver%20Fischer"> Oliver Fischer</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Hammad"> Ahmed Hammad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article, we study the prospects of the proposed Large Hadron electron Collider (LHeC) in the search for heavy neutral scalar particles. We consider a minimal model with one additional complex scalar singlet that interacts with the Standard Model (SM) via mixing with the Higgs doublet, giving rise to an SM-like Higgs boson and a heavy scalar particle. Both scalar particles are produced via vector boson fusion and can be tested via their decays into pairs of SM particles, analogously to the SM Higgs boson. Using multivariate techniques, we show that the LHeC is sensitive to heavy scalars with masses between 200 and 800 GeV down to scalar mixing of order 0.01. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beyond%20the%20standard%20model" title="beyond the standard model">beyond the standard model</a>, <a href="https://publications.waset.org/abstracts/search?q=large%20hadron%20electron%20collider" title=" large hadron electron collider"> large hadron electron collider</a>, <a href="https://publications.waset.org/abstracts/search?q=multivariate%20analysis" title=" multivariate analysis"> multivariate analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=scalar%20singlet" title=" scalar singlet"> scalar singlet</a> </p> <a href="https://publications.waset.org/abstracts/102214/neutral-heavy-scalar-searches-via-standard-model-gauge-boson-decays-at-the-large-hadron-electron-collider-with-multivariate-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102214.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">137</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">65</span> Viscoelastic Behavior of Human Bone Tissue under Nanoindentation Tests</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20Makuch">Anna Makuch</a>, <a href="https://publications.waset.org/abstracts/search?q=Grzegorz%20Kokot"> Grzegorz Kokot</a>, <a href="https://publications.waset.org/abstracts/search?q=Konstanty%20Skalski"> Konstanty Skalski</a>, <a href="https://publications.waset.org/abstracts/search?q=Jakub%20Banczorowski"> Jakub Banczorowski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cancellous bone is a porous composite of a hierarchical structure and anisotropic properties. The biological tissue is considered to be a viscoelastic material, but many studies based on a nanoindentation method have focused on their elasticity and microhardness. However, the response of many organic materials depends not only on the load magnitude, but also on its duration and time course. Depth Sensing Indentation (DSI) technique has been used for examination of creep in polymers, metals and composites. In the indentation tests on biological samples, the mechanical properties are most frequently determined for animal tissues (of an ox, a monkey, a pig, a rat, a mouse, a bovine). However, there are rare reports of studies of the bone viscoelastic properties on microstructural level. Various rheological models were used to describe the viscoelastic behaviours of bone, identified in the indentation process (e. g Burgers model, linear model, two-dashpot Kelvin model, Maxwell-Voigt model). The goal of the study was to determine the influence of creep effect on the mechanical properties of human cancellous bone in indentation tests. The aim of this research was also the assessment of the material properties of bone structures, having in mind the energy aspects of the curve (penetrator loading-depth) obtained in the loading/unloading cycle. There was considered how the different holding times affected the results within trabecular bone.As a result, indentation creep (CIT), hardness (HM, HIT, HV) and elasticity are obtained. Human trabecular bone samples (n=21; mean age 63±15yrs) from the femoral heads replaced during hip alloplasty were removed and drained from alcohol of 1h before the experiment. The indentation process was conducted using CSM Microhardness Tester equipped with Vickers indenter. Each sample was indented 35 times (7 times for 5 different hold times: t1=0.1s, t2=1s, t3=10s, t4=100s and t5=1000s). The indenter was advanced at a rate of 10mN/s to 500mN. There was used Oliver-Pharr method in calculation process. The increase of hold time is associated with the decrease of hardness parameters (HIT(t1)=418±34 MPa, HIT(t2)=390±50 MPa, HIT(t3)= 313±54 MPa, HIT(t4)=305±54 MPa, HIT(t5)=276±90 MPa) and elasticity (EIT(t1)=7.7±1.2 GPa, EIT(t2)=8.0±1.5 GPa, EIT(t3)=7.0±0.9 GPa, EIT(t4)=7.2±0.9 GPa, EIT(t5)=6.2±1.8 GPa) as well as with the increase of the elastic (Welastic(t1)=4.11∙10-7±4.2∙10-8Nm, Welastic(t2)= 4.12∙10-7±6.4∙10-8 Nm, Welastic(t3)=4.71∙10-7±6.0∙10-9 Nm, Welastic(t4)= 4.33∙10-7±5.5∙10-9Nm, Welastic(t5)=5.11∙10-7±7.4∙10-8Nm) and inelastic (Winelastic(t1)=1.05∙10-6±1.2∙10-7 Nm, Winelastic(t2) =1.07∙10-6±7.6∙10-8 Nm, Winelastic(t3)=1.26∙10-6±1.9∙10-7Nm, Winelastic(t4)=1.56∙10-6± 1.9∙10-7 Nm, Winelastic(t5)=1.67∙10-6±2.6∙10-7)) reaction of materials. The indentation creep increased logarithmically (R2=0.901) with increasing hold time: CIT(t1) = 0.08±0.01%, CIT(t2) = 0.7±0.1%, CIT(t3) = 3.7±0.3%, CIT(t4) = 12.2±1.5%, CIT(t5) = 13.5±3.8%. The pronounced impact of creep effect on the mechanical properties of human cancellous bone was observed in experimental studies. While the description elastic-inelastic, and thus the Oliver-Pharr method for data analysis, may apply in few limited cases, most biological tissues do not exhibit elastic-inelastic indentation responses. Viscoelastic properties of tissues may play a significant role in remodelling. The aspect is still under an analysis and numerical simulations.

The model uses the Navier-Stokes equation to simulate the dispersion of pollutants in the atmosphere. We considered as important factors in elaboration of simulation the atmospheric conditions (pressure, temperature, wind speed, wind direction), the exhaust velocity of the combustion gases, chimney height and the obstacles (buildings). Using the air quality monitoring stations we have measured the concentrations of main pollutants (SO2, NOx and PM). The pollutants were monitored over a period of 3 months, after that we calculated the average concentration, which is used by the software. The concentrations are: 8.915 μg/m3 (NOx), 9.587 μg/m3 (SO2) and 42 μg/m3 (PM). A comparison of test data with simulation results demonstrated that CFX was able to describe the dispersion of the pollutant as well the concentration of this pollutants in the atmosphere. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20pollutants" title="air pollutants">air pollutants</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title=" computational fluid dynamics"> computational fluid dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=dispersion" title=" dispersion"> dispersion</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/30889/numerical-simulation-of-the-air-pollutants-dispersion-emitted-by-cph-using-ansys-cfx" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30889.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">457</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">63</span> Public-Public Partnership and Tourism Development Strategy: The Case of Municipality of Gazi Baba in Macedonia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dejan%20Metodijeski">Dejan Metodijeski</a>, <a href="https://publications.waset.org/abstracts/search?q=Elizabeta%20Mitreva"> Elizabeta Mitreva</a>, <a href="https://publications.waset.org/abstracts/search?q=Nako%20Taskov"> Nako Taskov</a>, <a href="https://publications.waset.org/abstracts/search?q=Oliver%20Filiposki"> Oliver Filiposki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tourism development strategies are an important link in the tourism policy that is used to make its management better and easier. A public-public partnership (PUP) is a partnership between two or more public authorities or between a public authority and any non-profit organization with the goal of providing services and facilities or transferring technical skills. The paper presents this kind of partnership between two public authorities in Macedonia, the Municipality of Gazi Baba on one hand, and the University of Goce Delcev on the other. The main idea of this partnership is the development of a tourism strategy for the Municipality of Gazi Baba by the University on one side, and on the other, the construction of a mini park in the court of the University by the Municipality. This paper presents the causes and analyzes the procedures relating to this partnership and the methodology of the tourism development strategy. It contains a relevant literature review related to PUPs and tourism development strategy.

The synthetic route to 1 has been optimized, the importance of selecting a particular sequence of synthetic steps will be discussed. Three homoleptic complexes have been prepared, [Zn(1)₂]²⁺, [Fe(1)₂]²⁺ and [Ru(1)₂]²⁺, and have been isolated as the hexafluoridophosphate salts. Spectroelectrochemical measurements have been performed and the spectral changes ascribed to redox processes are partitioned on either the porphyrin or the terpyridine units. Compound 1 undergoes a reversible one-electron oxidation/reduction. The removal/gain of a second electron leads to a further irreversible chemical transformation. For the homoleptic [M(1)₂]²⁺ complexes, a suitable potential can be chosen at which both the oxidation and the reduction of the {ZnTPP} core are reversible. When the homoleptic complex contains a redox active metal such as Fe or Ru, spectroelectrochemistry has been used to investigate the metal to ligand charge transfer (MLCT) transition. The latter is sensitive to the oxidation state of the metal, and electrochemical oxidation of the metal center suppresses it. Detailed spectroelectrochemical studies will be presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=homoleptic%20complexes" title="homoleptic complexes">homoleptic complexes</a>, <a href="https://publications.waset.org/abstracts/search?q=spectroelectrochemistry" title=" spectroelectrochemistry"> spectroelectrochemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=tetraphenylporphyrinatozinc%28II%29" title=" tetraphenylporphyrinatozinc(II)"> tetraphenylporphyrinatozinc(II)</a>, <a href="https://publications.waset.org/abstracts/search?q=2" title=" 2"> 2</a>, <a href="https://publications.waset.org/abstracts/search?q=2%27%3A6%27" title="2':6'">2':6'</a>, <a href="https://publications.waset.org/abstracts/search?q=6%22-terpyridine" title="6"-terpyridine">6"-terpyridine</a> </p> <a href="https://publications.waset.org/abstracts/59759/homoleptic-complexes-of-a-tetraphenylporphyrinatozincii-conjugated-2266-terpyridine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59759.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">220</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">61</span> Kauffman Model on a Network of Containers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Johannes%20J.%20Schneider">Johannes J.

Füchslin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the description of the origin of life, there are still some open gaps, e.g., the formation of macromolecules cannot be fully explained so far. The Kauffman model proposes the existence of autocatalytic sets of macromolecules which mutually catalyze reactions leading to each other’s formation. Usually, this model is simulated in one well-stirred pot only, with a continuous inflow of small building blocks, from which larger molecules are created by a set of catalyzed ligation and cleavage reactions. This approach represents the picture of the primordial soup. However, the conditions on the early Earth must have differed geographically, leading to spatially different outcomes whether a specific reaction could be performed or not. Guided by this picture, the Kauffman model is simulated in a large number of containers in parallel, with neighboring containers being connected by diffusion. In each container, only a subset of the overall reaction set can be performed. Under specific conditions, this approach leads to a larger probability for the existence of an autocatalytic metabolism than in the original Kauffman model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agglomeration" title="agglomeration">agglomeration</a>, <a href="https://publications.waset.org/abstracts/search?q=autocatalytic%20set" title=" autocatalytic set"> autocatalytic set</a>, <a href="https://publications.waset.org/abstracts/search?q=differential%20equation" title=" differential equation"> differential equation</a>, <a href="https://publications.waset.org/abstracts/search?q=Kauffman%20model" title=" Kauffman model"> Kauffman model</a> </p> <a href="https://publications.waset.org/abstracts/182310/kauffman-model-on-a-network-of-containers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182310.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">58</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">60</span> Effect of Organic and Inorganic Fertilizers on the Growth and Yield of Physic Nut (Jatropha curcas)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oliver%20Echezona%20Ngwu">Oliver Echezona Ngwu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The research was conducted in 2011 cropping season at the Teaching and Research farm of the Faculty of Agriculture and Natural Resources Management, Enugu State University of Science and Technology, Enugu, Nigeria to study the effect of organic and inorganic fertilizers on the growth and yield of physic Nut (Jatropha curcas).

By far, PW is the largest waste stream by volume associated with oil and gas production operations. Due to the increasing volume of waste all over the world in the current decade, the outcome and effect of discharging PW on the environment has lately become a significant issue of environmental concerns. Therefore, there is a need for new technologies for PW treatment due to increase focus on water conservation and environmental regulation. The use of membrane processes for treatment of PW has several advantages over many of the traditional separation techniques. In oilfield produced water treatment with ceramic membranes, process efficiency is characterized by the specific permeate flux and by the oil separation performance. Apart from the membrane properties, the permeate flux during filtration of oily wastewaters is known to be strongly dependent on the constituents of the feed solution, as well as on process conditions, e.g. trans-membrane pressure (TMP) and cross-flow velocity (CFV). The research project presented in these report describes the application of different ceramic membrane filtration technologies for the efficient treatment of oil-field produced water and different model oily solutions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ceramic%20membrane" title="ceramic membrane">ceramic membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane%20fouling" title=" membrane fouling"> membrane fouling</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20rejection" title=" oil rejection"> oil rejection</a>, <a href="https://publications.waset.org/abstracts/search?q=produced%20water%20treatment" title=" produced water treatment"> produced water treatment</a> </p> <a href="https://publications.waset.org/abstracts/121611/ceramic-membrane-filtration-technologies-for-oilfield-produced-water-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121611.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">183</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">58</span> Acoustic Absorption of Hemp Walls with Ground Granulated Blast Slag</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oliver%20Kinnane">Oliver Kinnane</a>, <a href="https://publications.waset.org/abstracts/search?q=Aidan%20Reilly"> Aidan Reilly</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20Grimes"> John Grimes</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Pavia"> Sara Pavia</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosanne%20Walker"> Rosanne Walker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Unwanted sound reflection can create acoustic discomfort and lead to problems of speech comprehensibility. Contemporary building techniques enable highly finished internal walls resulting in sound reflective surfaces. In contrast, sustainable construction materials using natural and vegetal materials, are often more porous and absorptive. Hemp shiv is used as an aggregate and when mixed with lime binder creates a low-embodied-energy concrete. Cement replacements such as ground granulated blast slag (GGBS), a byproduct of other industrial processes, are viewed as more sustainable alternatives to high-embodied-energy cement. Hemp concretes exhibit good hygrothermal performance. This has focused much research attention on them as natural and sustainable low-energy alternatives to standard concretes. A less explored benefit is the acoustic absorption capability of hemp-based concretes. This work investigates hemp-lime-GGBS concrete specifically, and shows that it exhibits high levels of sound absorption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hemp" title="hemp">hemp</a>, <a href="https://publications.waset.org/abstracts/search?q=hempcrete" title=" hempcrete"> hempcrete</a>, <a href="https://publications.waset.org/abstracts/search?q=acoustic%20absorption" title=" acoustic absorption"> acoustic absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=GGBS" title=" GGBS"> GGBS</a> </p> <a href="https://publications.waset.org/abstracts/49146/acoustic-absorption-of-hemp-walls-with-ground-granulated-blast-slag" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49146.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">402</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">57</span> Improved Hydrogen Sorption Kinetics of Compacted LiNH₂-LiH Based Small Hydrogen Storage Tank by Doping with TiF₄ and MWCNTs </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chongsutthamani%20Sitthiwet">Chongsutthamani Sitthiwet</a>, <a href="https://publications.waset.org/abstracts/search?q=Praphatsorn%20Plerdsranoy"> Praphatsorn Plerdsranoy</a>, <a href="https://publications.waset.org/abstracts/search?q=Palmarin%20Dansirima"> Palmarin Dansirima</a>, <a href="https://publications.waset.org/abstracts/search?q=Priew%20Eiamlamai"> Priew Eiamlamai</a>, <a href="https://publications.waset.org/abstracts/search?q=Oliver%20Utke"> Oliver Utke</a>, <a href="https://publications.waset.org/abstracts/search?q=Rapee%20Utke"> Rapee Utke</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hydrogen storage tank containing compacted LiNH2-LiH is developed by doping with TiF₄ and multi-walled nanotubes (MWCNTs) to study kinetic properties. Transition metal-based catalyst (TiF₄) provides the catalytic effect on hydrogen dissociation/recombination, while MWCNTs benefit thermal conductivity and hydrogen permeability during de/rehydrogenation process. The Enhancement of dehydrogenation kinetics is observed from the single-step reaction at a narrower and lower temperature range of 150-350 ºC (100 ºC lower than the compacted LiNH₂-LiH without additives) as well as long plateau temperature and constant hydrogen flow rate (50 SCCM) up to 30 min during desorption. Besides, Hydrogen contents de/absorbed during 5-6 cycles increase from 1.90-2.40 to 3.10-4.70 wt. % H₂ (from 29 to up to 80 % of theoretical capacity). In the process, Li₅TiN₃ is detected upon cycling probably absorbs NH₃ to form Li₅TiN₃(NH₃)x, which is favoring hydrogen sorption properties of the LiNH₂-LiH system. Importantly, the homogeneous reaction mechanisms and performances are found at all positions inside the tank of compacted LiNH₂-LiH doped with TiF₄ and MWCNTs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon" title="carbon">carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=hydride" title=" hydride"> hydride</a>, <a href="https://publications.waset.org/abstracts/search?q=kinetics" title=" kinetics"> kinetics</a>, <a href="https://publications.waset.org/abstracts/search?q=dehydrogenation" title=" dehydrogenation"> dehydrogenation</a> </p> <a href="https://publications.waset.org/abstracts/121181/improved-hydrogen-sorption-kinetics-of-compacted-linh2-lih-based-small-hydrogen-storage-tank-by-doping-with-tif4-and-mwcnts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121181.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">145</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">56</span> Other-Generated Disclosure: A Challenge to Privacy on Social Network Sites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tharntip%20Tawnie%20Chutikulrungsee">Tharntip Tawnie Chutikulrungsee</a>, <a href="https://publications.waset.org/abstracts/search?q=Oliver%20Kisalay%20Burmeister"> Oliver Kisalay Burmeister</a>, <a href="https://publications.waset.org/abstracts/search?q=Maumita%20Bhattacharya"> Maumita Bhattacharya</a>, <a href="https://publications.waset.org/abstracts/search?q=Dragana%20Calic"> Dragana Calic</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sharing on social network sites (SNSs) has rapidly emerged as a new social norm and has become a global phenomenon. Billions of users reveal not only their own information (self disclosure) but also information about others (other-generated disclosure), resulting in a risk and a serious threat to either personal or informational privacy. Self-disclosure (SD) has been extensively researched in the literature, particularly regarding control of individual and existing privacy management. However, far too little attention has been paid to other-generated disclosure (OGD), especially by insiders. OGD has a strong influence on self-presentation, self-image, and electronic word of mouth (eWOM). Moreover, OGD is more credible and less likely manipulated than SD, but lacks privacy control and legal protection to some extent. This article examines OGD in depth, ranging from motivation to both online and offline impacts, based upon lived experiences from both ‘the disclosed’ and ‘the discloser’. Using purposive sampling, this phenomenological study involves an online survey and in-depth interviews. The findings report the influence of peer disclosure as well as users’ strategies to mitigate privacy issues. This article also calls attention to the challenge of OGD privacy and inadequacies in the law related to privacy protection in the digital domain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=facebook" title="facebook">facebook</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20privacy" title=" online privacy"> online privacy</a>, <a href="https://publications.waset.org/abstracts/search?q=other-generated%20disclosure" title=" other-generated disclosure"> other-generated disclosure</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20networks%20sites%20%28SNSs%29" title=" social networks sites (SNSs)"> social networks sites (SNSs)</a> </p> <a href="https://publications.waset.org/abstracts/66391/other-generated-disclosure-a-challenge-to-privacy-on-social-network-sites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66391.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">251</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">55</span> PhilSHORE: Development of a WebGIS-Based Marine Spatial Planning Tool for Tidal Current Energy Resource Assessment and Site Suitability Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ma.%20Rosario%20Concepcion%20O.%20Ang">Ma.

Its platform is based on Geographic Information Systems (GIS) which allows for the collection, storage, processing, analyses and display of geospatial data. Combining GIS tools with open source web development applications, PhilSHORE becomes a webGIS-based marine spatial planning tool. To date, PhilSHORE displays output maps and graphs of power and energy density, site suitability and site-device analysis. It enables stakeholders and the public easy access to the results of tidal current energy resource assessments and site suitability analyses. Results of the initial development shows PhilSHORE is a promising decision support tool for ORE project developments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gis" title="gis">gis</a>, <a href="https://publications.waset.org/abstracts/search?q=site%20suitability%20analysis" title=" site suitability analysis"> site suitability analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=tidal%20current%20energy%20resource%20assessment" title=" tidal current energy resource assessment"> tidal current energy resource assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=webgis" title=" webgis"> webgis</a> </p> <a href="https://publications.waset.org/abstracts/30163/philshore-development-of-a-webgis-based-marine-spatial-planning-tool-for-tidal-current-energy-resource-assessment-and-site-suitability-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30163.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">525</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">54</span> 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">53</span> Cultural Impact on Fairness Perception of Inequality: A Study on People With Chinese Roots Living in Germany</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yanping%20He-Ulbricht">Yanping He-Ulbricht</a>, <a href="https://publications.waset.org/abstracts/search?q=Marc%20Oliver%20Rieger"> Marc Oliver Rieger</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Based on survey data collected from people with Chinese roots living in Germany, this paper examines the impact of assimilation degree and language priming (Chinese or German) on individuals’ perceived fairness of economic and social differences and their attitude towards these. The results show that both the language used and the length of time spent in a foreign culture have a significant impact. Subjects who had spent less than 10 years in Germany demonstrated a higher readiness to accept government intervention in markets with price limits than those who had lived there longer. Subjects who were asked and answered in German perceived the current economic situation as less fair and were also less inclined to accept inequality, even when it leads to a Pareto improvement. While the difference in fairness perception of inequality was a cultural effect, the difference in attitudes towards government intervention was rather a result of learning process. The findings imply that both learning processes of individuals and culture play an important role in perception and preferences regarding social and economic differences. <p
