Kida</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We consider the flow of an incompressible viscous fluid in a precessing sphere whose spin and precession axes are orthogonal to each other. The flow is characterized by two non-dimensional parameters, the Reynolds number Re and the Poincare number Po. For which values of (Re, Po) will the flow approach a steady state from an arbitrary initial condition? To answer it we are searching the instability boundary of the steady states in the whole (Re, Po) plane. Here, we focus the rapidly rotating and weakly precessing limit, i.e., Re >> 1 and Po << 1. The steady flow was obtained by the asymptotic expansion for small ε=Po Re¹/² << 1. The flow exhibits nearly a solid-body rotation in the whole sphere except for a thin boundary layer which develops over the sphere surface. The thickness of this boundary layer is of O(δ), where δ=Re⁻¹/², except where two circular critical bands of thickness of O(δ⁴/⁵) and of width of O(δ²/⁵) which are located away from the spin axis by about 60°. We perform the linear stability analysis of the steady flow. We assume that the disturbances are localized in the critical bands and make an expansion analysis in terms of ε to derive the eigenvalue problem for the growth rate of the disturbance, which is solved numerically. As the solution, we obtain an asymptote of the stability boundary as Po=28.36Re⁻⁰.⁸. This agrees excellently with the corresponding laboratory experiments and numerical simulations. One of the most popular instability mechanisms so far is the parametric instability, which turns out, however, not to give the correct stability boundary. The present instability is different from the parametric instability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boundary%20layer" title="boundary layer">boundary layer</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20band" title=" critical band"> critical band</a>, <a href="https://publications.waset.org/abstracts/search?q=instability" title=" instability"> instability</a>, <a href="https://publications.waset.org/abstracts/search?q=precessing%20sphere" title=" precessing sphere"> precessing sphere</a> </p> <a href="https://publications.waset.org/abstracts/99149/instability-by-weak-precession-of-the-flow-in-a-rapidly-rotating-sphere" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99149.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">376</span> Self in Networks: Public Sphere in the Era of Globalisation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sanghamitra%20Sadhu">Sanghamitra Sadhu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A paradigm shift from capitalism to information technology is discerned in the era globalisation. The idea of public sphere, which was theorized in terms of its decline in the wake of the rise of commercial mass media has now emerged as a transnational or global sphere with the discourse being dominated by the ‘network society’. In other words, the dynamic of globalisation has brought about ‘a spatial turn’ in the social and political sciences which is also manifested in the public sphere, Especially the global public sphere. The paper revisits the Habermasian concept of the public sphere and focuses on the various social networking sites with their plausibility to create a virtual global public sphere. Situating Habermas’s notion of the bourgeois public sphere in the present context of global public sphere, it considers the changing dimensions of the public sphere across time and examines the concept of the ‘public’ with its shifting transformation from the concrete collective to the fluid ‘imagined’ category. The paper addresses the problematic of multimodal self-portraiture in the social networking sites as well as various online diaries/journals with an attempt to explore the nuances of the networked self. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=globalisation" title="globalisation">globalisation</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20society" title=" network society"> network society</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20sphere" title=" public sphere"> public sphere</a>, <a href="https://publications.waset.org/abstracts/search?q=self-fashioning" title=" self-fashioning"> self-fashioning</a>, <a href="https://publications.waset.org/abstracts/search?q=identity" title=" identity"> identity</a>, <a href="https://publications.waset.org/abstracts/search?q=autonomy" title=" autonomy"> autonomy</a> </p> <a href="https://publications.waset.org/abstracts/28132/self-in-networks-public-sphere-in-the-era-of-globalisation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28132.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">416</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">375</span> Rethinking the Public Sphere: Group Polarization on Social Media</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tianji%20Jiang">Tianji Jiang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Habermas' definition of public sphere is a classical and well-regarded theory of the formation of public opinions, laying the foundation for many researches on public opinions and public media. In recent decades, public media have been changing rapidly as social media are gaining increasing importance. However, the occurrence of group polarization on social media, which is a hot issue today, is challenging Habermas' theory of the public sphere. This article reviews the public sphere theory and studies group polarization and social media.

It is obtained using elementary geometry, yet, it converges, in the weak sense, to the solutions to the Smoluchowski equation. Rotations on the sphere, which are the analogs of linear displacements in euclidean spaces, are calculated using algebraic operations and then by a proper scaling, which makes the algorithm efficient and quite simple, especially to what may be the short-time propagator approach. Our findings prove that the global effects of curvature are taken into account in both dynamic and stationary processes, and it is not restricted to work in configuration space, neither restricted to the overdamped limit. We have generalized it successfully to simulate the Kramers or the Ornstein-Uhlenbeck process, where it is necessary to work directly in phase space, and it may be adapted to other two dimensional surfaces with non-constant curvature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diffusion%20on%20the%20sphere" title="diffusion on the sphere">diffusion on the sphere</a>, <a href="https://publications.waset.org/abstracts/search?q=Fokker-Planck%20equation%20on%20the%20sphere" title=" Fokker-Planck equation on the sphere"> Fokker-Planck equation on the sphere</a>, <a href="https://publications.waset.org/abstracts/search?q=non%20equilibrium%20processes%20on%20the%20sphere" title=" non equilibrium processes on the sphere"> non equilibrium processes on the sphere</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20methods%20for%20diffusion%20on%20the%20sphere" title=" numerical methods for diffusion on the sphere"> numerical methods for diffusion on the sphere</a> </p> <a href="https://publications.waset.org/abstracts/126691/a-geometrical-method-for-the-smoluchowski-equation-on-the-sphere" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126691.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">181</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">373</span> Green and Facile Fabrication and Characterization of Fe/ZnO Hollow Spheres and Photodegradation of Azo Dyes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mohsen%20Mousavi">Seyed Mohsen Mousavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Reza%20Mahjoub"> Ali Reza Mahjoub</a>, <a href="https://publications.waset.org/abstracts/search?q=Bahjat%20Afshari%20Razani"> Bahjat Afshari Razani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, Fe/ZnO hollow spherical structures with high surface area using the template glucose was prepared by the hydrothermal method using an ultrasonic bath at room temperature was produced and were identified by FT-IR, XRD, FE-SEM and BET.

This presentation focuses on the transpersonal that goes beyond the individual (trans-personal) to encompass wider aspects of humanities, specifically peak experience as a culminating stage of the creative act. It proposes a model according to which the peak experience results from a harmonious vibration of four spheres, which transcend an individual’s capacities and bring one to a qualitatively different level of experience. Each sphere represents an aspect of creative activity: superconscious, intellectual, emotive and active. Each sphere corresponds to one of four creative functions: authenticity, novelty, aesthetics, and utility, respectively. The creative act starts in the superconscious sphere: the supreme pleasure of Creation is reflected in creative pleasure, which is realized in creative will. These three instances serve as a source of force axes, which penetrate other spheres, and in place of infiltration establish restrictive, expansive, and integrative principles, respectively; the latter balances the other two and ensures a harmonious vibration within a sphere. This Hegelian-like triad is realized within each sphere in the form of creative capacities. The intellectual sphere nurtures capacities to invent and to elaborate, which are integrated by capacity to conceptualize. The emotive sphere nurtures satiation and restrictive capacities integrated by capacity to balance. The active sphere nurtures goal orientation and stabilization capacities integrated by capacity for self-expression. All four spheres vibrate within each other – the superconscious sphere being in the core of the structure followed by intellectual, emotive, and active spheres, respectively – thereby reflecting the path of creative production. If the spheres vibrate in-phase, their amplitudes amplify the creative energy; if in antiphase – the amplitudes reduce the creative energy. Thus, creative act is perceived as continuum with perfectly harmonious vibration within and between the spheres on one side and perfectly disharmonious vibration on the other. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=creativity" title="creativity">creativity</a>, <a href="https://publications.waset.org/abstracts/search?q=model" title=" model"> model</a>, <a href="https://publications.waset.org/abstracts/search?q=transpersonal" title=" transpersonal"> transpersonal</a>, <a href="https://publications.waset.org/abstracts/search?q=peak%20experience" title=" peak experience"> peak experience</a> </p> <a href="https://publications.waset.org/abstracts/42946/transpersonal-model-of-an-individuals-creative-experiencef" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42946.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">370</span> Analysis of the Scattered Fields by Dielectric Sphere Inside Different Dielectric Mediums: The Case of the Source and Observation Point Is Reciprocal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emi%CC%87ne%20Av%C5%9Far%20Aydin">Emi̇ne Avşar Aydin</a>, <a href="https://publications.waset.org/abstracts/search?q=Nezahat%20G%C3%BCnen%C3%A7%20Tuncel"> Nezahat Günenç Tuncel</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Hami%CC%87t%20Serbest"> A.

In this study, the electromagnetic scattering from a dielectric sphere with oblique incidence is investigated. The incident field is considered as a plane wave with H polarized. The scattered and transmitted field expressions with unknown coefficients are written. The unknown coefficients are obtained by using exact boundary conditions. Then, the sphere is considered as having frequency dependent dielectric permittivity. The frequency dependence is shown by Cole-Cole model. The far scattered field expressions are found respect to different incidence angles in the 1-8 GHz frequency range. The observation point is the angular distance of pi from an incident wave. While an incident wave comes with a certain angle, observation point turns from 0 to 360 degrees. According to this, scattered field amplitude is maximum at the location of the incident wave, scattered field amplitude is minimum at the across incident wave. Also, the scattered fields are plotted versus frequency to show frequency-dependence explicitly. Graphics are shown for some incident angles compared with the Harrington's solution. Thus, the results are obtained faster and more reliable with reciprocal rotation. It is expected that when there is another sphere with different properties in the outer sphere, the presence and location of the sphere will be detected faster. In addition, this study leads to use for biomedical applications in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=scattering" title="scattering">scattering</a>, <a href="https://publications.waset.org/abstracts/search?q=dielectric%20sphere" title=" dielectric sphere"> dielectric sphere</a>, <a href="https://publications.waset.org/abstracts/search?q=oblique%20incidence" title=" oblique incidence"> oblique incidence</a>, <a href="https://publications.waset.org/abstracts/search?q=reciprocal%20rotation" title=" reciprocal rotation"> reciprocal rotation</a> </p> <a href="https://publications.waset.org/abstracts/32409/analysis-of-the-scattered-fields-by-dielectric-sphere-inside-different-dielectric-mediums-the-case-of-the-source-and-observation-point-is-reciprocal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32409.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">298</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">369</span> The Lived Experience of Siblings of Autistic Children; From the Private to Public Sphere</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kiana%20Taghikhan">Kiana Taghikhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shamim%20Sherafat"> Shamim Sherafat</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Taheri"> Mostafa Taheri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although many people with autism spectrum disorder around the world face many problems and challenges, their conditions may unintentionally affect the lives of the people around them. In this research the experiences of siblings of autistic children have been investigated in both the public and private spheres of their lives. "Private sphere" includes the experiences of research participants in socializing with relatives and family, assignments and responsibilities, as well as how they spend their leisure time and lifestyle. The "public sphere" includes the experience of their presence in society, such as university, or workplace and any outdoor activities that could have been affected by their sibling’s disorder. The present research has been done using the qualitative research method and in-depth interview technique with siblings of autistic children. The sample population is 15 individuals who participated in the research theoretically and purposefully. Based on the findings, the private and social experiences of these individuals is very different compared to peers who do not have siblings with autism disorder in the family. The difference is to such an extent that causes them to separate and distance themselves from other members of the society, and depending on their special conditions, it can affect their goals and life opportunities such as job, marriage, having children, etc. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autism%20spectrum%20disorder" title="autism spectrum disorder">autism spectrum disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=siblings" title=" siblings"> siblings</a>, <a href="https://publications.waset.org/abstracts/search?q=private%20sphere" title=" private sphere"> private sphere</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20sphere" title=" public sphere"> public sphere</a> </p> <a href="https://publications.waset.org/abstracts/190021/the-lived-experience-of-siblings-of-autistic-children-from-the-private-to-public-sphere" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190021.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">29</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">368</span> Some Aspects of Improving Service Sphere Management in Georgia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gechbaia%20Badri">Gechbaia Badri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the article, it is studied and realized the perfection issues of service sphere management in Georgia’s reality.

Some bed materials with bad fluidized performance always fluidize with fluidized medium. The material and the fluidized medium are different in many properties such as density, size and shape. These factors make the dynamic process more complex and the experiment research more limited. Numerical simulation is an efficient way to describe the process of gas-solid flow in fluidized bed. One of the most popular numerical simulation methods is CFD-DEM, i.e., computational fluid dynamics-discrete element method. The shapes of particles are always simplified as sphere in most researches. Although sphere-shaped particles make the calculation of particle uncomplicated, the effects of different shapes are disregarded. However, in practical applications, the two-component systems in fluidized bed also contain sphere particles and non-sphere particles. Therefore, it is needed to study the two component flow of sphere particles and non-sphere particles. In this paper, the flows of mixing were simulated as the flow of molding biomass particles and quartz in fluidized bad. The integrated model was built on an Eulerian–Lagrangian approach which was improved to suit the non-sphere particles. The constructed methods of cylinder-shaped particles were different when it came to different numerical methods. Each cylinder-shaped particle was constructed as an agglomerate of fictitious small particles in CFD part, which means the small fictitious particles gathered but not combined with each other. The diameter of a fictitious particle d_fic and its solid volume fraction inside a cylinder-shaped particle α_fic, which is called the fictitious volume fraction, are introduced to modify the drag coefficient β by introducing the volume fraction of the cylinder-shaped particles α_cld and sphere-shaped particles α_sph. In a computational cell, the void ε, can be expressed as ε=1-〖α_cld α〗_fic-α_sph. The Ergun equation and the Wen and Yu equation were used to calculate β. While in DEM method, cylinder-shaped particles were built by multi-sphere method, in which small sphere element merged with each other. Soft sphere model was using to get the connect force between particles. The total connect force of cylinder-shaped particle was calculated as the sum of the small sphere particles’ forces. The model (size=1×0.15×0.032 mm3) contained 420000 sphere-shaped particles (diameter=0.8 mm, density=1350 kg/m3) and 60 cylinder-shaped particles (diameter=10 mm, length=10 mm, density=2650 kg/m3). Each cylinder-shaped particle was constructed by 2072 small sphere-shaped particles (d=0.8 mm) in CFD mesh and 768 sphere-shaped particles (d=3 mm) in DEM mesh. The length of CFD and DEM cells are 1 mm and 2 mm. Superficial gas velocity was changed in different models as 1.0 m/s, 1.5 m/s, 2.0m/s. The results of simulation were compared with the experimental results. The movements of particles were regularly as fountain. The effect of superficial gas velocity on cylinder-shaped particles was stronger than that of sphere-shaped particles. The result proved this present work provided a effective approach to simulation the flow of two component particles. <p class="card-text"><strong>Keywords:</strong> <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=discrete%20element%20method" title=" discrete element method"> discrete element method</a>, <a href="https://publications.waset.org/abstracts/search?q=fluidized%20bed" title=" fluidized bed"> fluidized bed</a>, <a href="https://publications.waset.org/abstracts/search?q=multiphase%20flow" title=" multiphase flow"> multiphase flow</a> </p> <a href="https://publications.waset.org/abstracts/36080/numerical-simulation-on-two-components-particles-flow-in-fluidized-bed" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36080.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">326</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">366</span> Experimental Study of Unconfined and Confined Isothermal Swirling Jets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rohit%20Sharma">Rohit Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabio%20Cozzi"> Fabio Cozzi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A 3C-2D PIV technique was applied to investigate the swirling flow generated by an axial plus tangential type swirl generator. This work is focused on the near-exit region of an isothermal swirling jet to characterize the effect of swirl on the flow field and to identify the large coherent structures both in unconfined and confined conditions for geometrical swirl number, S<sub>g </sub>= 4.6. Effects of the Reynolds number on the flow structure were also studied. The experimental results show significant effects of the confinement on the mean velocity fields and its fluctuations. The size of the recirculation zone was significantly enlarged upon confinement compared to the free swirling jet. Increasing in the Reynolds number further enhanced the recirculation zone. The frequency characteristics have been measured with a capacitive microphone which indicates the presence of periodic oscillation related to the existence of precessing vortex core, PVC. Proper orthogonal decomposition of the jet velocity field was carried out, enabling the identification of coherent structures. The time coefficients of the first two most energetic POD modes were used to reconstruct the phase-averaged velocity field of the oscillatory motion in the swirling flow. The instantaneous minima of negative swirl strength values calculated from the instantaneous velocity field revealed the presence of two helical structures located in the inner and outer shear layers and this structure fade out at an axial location of approximately z/D = 1.5 for unconfined case and z/D = 1.2 for confined case. By phase averaging the instantaneous swirling strength maps, the 3D helical vortex structure was reconstructed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acoustic%20probes" title="acoustic probes">acoustic probes</a>, <a href="https://publications.waset.org/abstracts/search?q=3C-2D%20particle%20image%20velocimetry%20%28PIV%29" title=" 3C-2D particle image velocimetry (PIV)"> 3C-2D particle image velocimetry (PIV)</a>, <a href="https://publications.waset.org/abstracts/search?q=precessing%20vortex%20core%20%28PVC%29" title=" precessing vortex core (PVC)"> precessing vortex core (PVC)</a>, <a href="https://publications.waset.org/abstracts/search?q=recirculation%20zone%20%28RZ%29" title=" recirculation zone (RZ)"> recirculation zone (RZ)</a> </p> <a href="https://publications.waset.org/abstracts/65660/experimental-study-of-unconfined-and-confined-isothermal-swirling-jets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65660.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">233</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">365</span> Measurement of the Neutron Spectrum of 241AmLi and 241AmF Sources Using the Bonner Sphere Spectrometers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victor%20Rocha%20Carvalho">Victor Rocha Carvalho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Bonner Sphere Spectrometry was used to obtain the average energy, the fluence rate, and radioprotection quantities such as the personal and ambient dose equivalent of the ²⁴¹AmLi and ²⁴¹AmF isotopic neutron sources used in the Neutron Metrology Laboratory - LN.

Through this, the neutron spectrum was obtained by means of the software named NeuraLN, developed by the LN, that uses the neural networks technique. The 241AmLi achieved a result close to the literature, and 241AmF, which contains few published references, acquired a result with a slight variation from the literature. Therefore, besides fulfilling its objective, the work raises questions about a possible standard of the ²⁴¹AmLi and about the lack of work with the ²⁴¹AmF. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nuclear%20physics" title="nuclear physics">nuclear physics</a>, <a href="https://publications.waset.org/abstracts/search?q=neutron%20metrology" title=" neutron metrology"> neutron metrology</a>, <a href="https://publications.waset.org/abstracts/search?q=neutron%20spectrometry" title=" neutron spectrometry"> neutron spectrometry</a>, <a href="https://publications.waset.org/abstracts/search?q=bonner%20sphere%20spectrometers" title=" bonner sphere spectrometers"> bonner sphere spectrometers</a> </p> <a href="https://publications.waset.org/abstracts/160581/measurement-of-the-neutron-spectrum-of-241amli-and-241amf-sources-using-the-bonner-sphere-spectrometers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160581.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">102</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">364</span> Synthesis and Characterization of the Carbon Spheres Built Up from Reduced Graphene Oxide</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Takahiro%20Saida">Takahiro Saida</a>, <a href="https://publications.waset.org/abstracts/search?q=Takahiro%20Kogiso"> Takahiro Kogiso</a>, <a href="https://publications.waset.org/abstracts/search?q=Takahiro%20Maruyama"> Takahiro Maruyama</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ordered structural carbon (OSC) material is expected to apply to the electrode of secondary batteries, the catalyst supports, and the biomaterials because it shows the low substance-diffusion resistance by its uniform pore size. In general, the OSC material is synthesized using the template material. Changing size and shape of this template provides the pore size of OSC material according to the purpose. Depositing the oxide nanosheets on the polymer sphere template by the layer by layer (LbL) method was reported as one of the preparation methods of OSC material. The LbL method can provide the controlling thickness of structural wall without the surface modification. When the preparation of the uniform carbon sphere prepared by the LbL method which composed of the graphene oxide wall and the polymethyl-methacrylate (PMMA) core, the reduction treatment will be the important object. Since the graphene oxide has poor electron conductivity due to forming a lot of functional groups on the surface, it could be hard to apply to the electrode of secondary batteries and the catalyst support of fuel cells. In this study, the graphene oxide wall of carbon sphere was reduced by the thermal treatment under the vacuum conditions, and its crystalline structure and electronic state were characterized. Scanning electron microscope images of the carbon sphere after the heat treatment at 300ºC showed maintaining sphere shape, but its shape was collapsed with increasing the heating temperature. In this time, the dissolution rate of PMMA core and the reduction rate of graphene oxide were proportionate to heating temperature. In contrast, extending the heating time was conducive to the conservation of the sphere shape. From results of X-ray photoelectron spectroscopy analysis, its electronic state of the surface was indicated mainly sp² carbon. From the above results, we succeeded in the synthesis of the sphere structure composed by the reduction graphene oxide. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20sphere" title="carbon sphere">carbon sphere</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene%20oxide" title=" graphene oxide"> graphene oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=reduction" title=" reduction"> reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=layer%20by%20layer" title=" layer by layer"> layer by layer</a> </p> <a href="https://publications.waset.org/abstracts/90727/synthesis-and-characterization-of-the-carbon-spheres-built-up-from-reduced-graphene-oxide" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90727.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">141</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">363</span> Elastoplastic and Ductile Damage Model Calibration of Steels for Bolt-Sphere Joints Used in China’s Space Structure Construction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huijuan%20Liu">Huijuan Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Fukun%20Li"> Fukun Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Hao%20Yuan"> Hao Yuan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The bolted spherical node is a common type of joint in space steel structures. The bolt-sphere joint portion almost always controls the bearing capacity of the bolted spherical node. The investigation of the bearing performance and progressive failure in service often requires high-fidelity numerical models. This paper focuses on the constitutive models of bolt steel and sphere steel used in China’s space structure construction. The elastoplastic model is determined by a standard tensile test and calibrated Voce saturated hardening rule. The ductile damage is found dominant based on the fractography analysis. Then Rice-Tracey ductile fracture rule is selected and the model parameters are calibrated based on tensile tests of notched specimens.

To do so, will be presented initially the idea of the public sphere (by Jürgen Habermas), showing how it is presented as an interface between the citizen and the state (or the private and public) and how important is it in a deliberative democracy. Based on this paradigm, the traditional perception of the role of public information (such as system functional element) and on the possibility of media regulation will be exposed, due to the public nature of their activity. A critical argument will then be displayed from two different perspectives: a) the formal function of the current media information, considering that the digital age has fragmented the information access; b) the concept of a constructive democracy, which reduces the need for representation, changing the strategic importance of the public sphere. The question to be addressed (based on the comparative law) is if the regulation is justified in a polycentric democracy, especially when it operates under the digital age (with immediate and virtual communication). The proposal is to be presented in the sense that even in a twenty-first century the media in a democratic rule of law still has an extremely important role and may be subject to regulation, but this should be on terms very different (and narrower) from those usually defended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constructive%20democracy" title="constructive democracy">constructive democracy</a>, <a href="https://publications.waset.org/abstracts/search?q=media" title=" media"> media</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20age" title=" digital age"> digital age</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20sphere" title=" public sphere"> public sphere</a> </p> <a href="https://publications.waset.org/abstracts/25585/media-regulation-and-public-sphere-in-the-digital-age-an-analysis-in-the-light-of-constructive-democracy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25585.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">380</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">361</span> Muslims in Diaspora Negotiating Islam through Muslim Public Sphere and the Role of Media</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabah%20Khan">Sabah Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The idea of universal Islam tends to exaggerate the extent of homogeneity in Islamic beliefs and practices across Muslim communities. In the age of migration, various Muslim communities are in diaspora. The immediate implication of this is what happens to Islam in diaspora? How Islam gets represented in new forms? Such pertinent questions need to be dealt with. This paper shall draw on the idea of religious transnationalism, primarily transnational Islam. There are multiple ways to conceptualize transnational phenomenon with reference to Islam in terms of flow of people, transnational organizations and networks; Ummah oriented solidarity and the new Muslim public sphere. This paper specifically deals with the new Muslim public sphere. It primarily refers to the space and networks enabled by new media and communication technologies, whereby Muslim identity and Islamic normativity are rehearsed, debated by people in different locales. A new sense of public is emerging across Muslim communities, which needs to be contextualized. This paper uses both primary and secondary data. Primary data elicited through content analysis of audio-visuals on social media and secondary sources of information ranging from books, articles, journals, etc. The basic aim of the paper is to focus on the emerging Muslim public sphere and the role of media in expanding public spheres of Islam. It also explores how Muslims in diaspora negotiate Islam and Islamic practices through media and the new Muslim public sphere. This paper cogently weaves in discussions firstly, of re-intellectualization of Islamic discourse in the public sphere. In other words, how Muslims have come to reimagine their collective identity and critically look at fundamental principles and authoritative tradition. Secondly, the emerging alternative forms of Islam by young Muslims in diaspora. In other words, how young Muslims search for unorthodox ways and media for religious articulation, including music, clothing and TV. This includes transmission and distribution of Islam in diaspora in terms of emerging ‘media Islam’ or ‘soundbite Islam’. The new Muslim public sphere has offered an arena to a large number of participants to critically engage with Islam, which leads not only to a critical engagement with traditional forms of Islamic authority but also emerging alternative forms of Islam and Islamic practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Islam" title="Islam">Islam</a>, <a href="https://publications.waset.org/abstracts/search?q=media" title=" media"> media</a>, <a href="https://publications.waset.org/abstracts/search?q=Muslims" title=" Muslims"> Muslims</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20sphere" title=" public sphere"> public sphere</a> </p> <a href="https://publications.waset.org/abstracts/74341/muslims-in-diaspora-negotiating-islam-through-muslim-public-sphere-and-the-role-of-media" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74341.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">270</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">360</span> Musical Tesla Coil Controlled by an Audio Signal Processed in Matlab</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Cuenca">Sandra Cuenca</a>, <a href="https://publications.waset.org/abstracts/search?q=Danilo%20Santana"> Danilo Santana</a>, <a href="https://publications.waset.org/abstracts/search?q=Anderson%20Reyes"> Anderson Reyes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The following project is based on the manipulation of audio signals through the Matlab software, which has an audio signal that is modified, and its resultant obtained through the auxiliary port of the computer is passed through a signal amplifier whose amplified signal is connected to a tesla coil which has a behavior like a vumeter, the flashes at the output of the tesla coil increase and decrease its intensity depending on the audio signal in the computer and also the voltage source from which it is sent.

Both the UK, after the Glorious Revolution in the seventeenth century, and China, after its adoption of the open door policy at the end of the 1970s, follow such a path of development. The difference between the UK and China in moving toward that path is the different coordination of elites. While the coordination of elites in the UK through parliament played important roles in forcing the government to consider the wider encompassing interest in society after the Glorious Revolution, the coordination of elites in China has mainly been achieved by the Communist Party of China such that the Chinese Government has started to pay greater deal of attention to the wider encompassing interest in the country from 1978. The article has also examined the rise of the US following colonial settlement to independence and institutional building thereafter. The US case is similarly consistent with the argument that open access in the economic sphere and institutional building matter the most to economic development. More decentralized methods of the coordination of elites in the US among colonies (states), the federal governments, and other political groups similarly shaped the path towards open access in the economic sphere and institutional building. As such, open access in the political sphere plays an indirect role in development at best. If that is correct, there are possibilities that different political systems are able to achieve coordination of elites so that governments will turn their attention to development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=open%20access" title="open access">open access</a>, <a href="https://publications.waset.org/abstracts/search?q=interconnected%20institutions" title=" interconnected institutions"> interconnected institutions</a>, <a href="https://publications.waset.org/abstracts/search?q=democracy" title=" democracy"> democracy</a>, <a href="https://publications.waset.org/abstracts/search?q=development" title=" development"> development</a> </p> <a href="https://publications.waset.org/abstracts/160962/open-access-in-the-economic-sphere-a-framework-interpreting-the-rise-of-the-uk-us-and-china-at-different-historical-times" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160962.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">80</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">358</span> The Making of a Yijing (Classic of Changes) Cultural Sphere in Asia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ng%20Wai%20Ming">Ng Wai Ming</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Yijing (Classic of Changes) is one of the most influential Chinese classics, and its text, images and divination have been widely studied and used by different people in the world from past to present.

Because of their unprecedented activity in the region and foreign recruitment success, this study specifically addresses how the Islamic State (IS/ISIS/ISIL) manipulates the public sphere to amplify support and increase western recruitment. By following a grounded theory methodology and coding triangulated data from IS propaganda, a model for the process of terrorist recruitment has emerged, concerning both environments and personalities susceptible to recruitment, and the steps by which an extremist can be created. This has resulted in the ability to reverse engineer a method by which counter recruitment operations can be facilitated in an effort to lessen the vulnerability of areas and individuals, as well as create dissent among current extremists. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=countering%20violent%20extremism" title="countering violent extremism">countering violent extremism</a>, <a href="https://publications.waset.org/abstracts/search?q=counter-terrorism" title=" counter-terrorism"> counter-terrorism</a>, <a href="https://publications.waset.org/abstracts/search?q=recruitment" title=" recruitment"> recruitment</a>, <a href="https://publications.waset.org/abstracts/search?q=overton%20window" title=" overton window"> overton window</a> </p> <a href="https://publications.waset.org/abstracts/45665/manipulation-of-the-public-sphere-to-win-cultural-hegemony-the-process-by-which-islamic-state-uses-the-principles-of-the-overton-window-to-engineer-extremism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45665.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">344</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">356</span> Retrospective Insight on the Changing Status of the Romanian Language Spoken in the Republic of Moldova</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gina%20Aurora%20Necula">Gina Aurora Necula</a> </p> <p class="card-text"><strong>Abstract:</strong></p> From its transformation into a taboo and its hiding under the so-called “Moldovan language” or under the euphemistic expression “state language” to its regained status recognition as an official language, the Romanian language spoken in the Republic of Moldova has undergone impressive reforms in the last 60 years. Meant to erase the awareness of citizens’ ethnic identity and turn a majority language into a minority one, all the laws and regulations issued on the field succeeded into setting numerous barriers for speakers of Romanian. Either manifested as social constraints or materialized into assumed rejection of mother tongue usage, all these laws have demonstrated their usefulness and major impact on the Romanian-speaking population. This article is the result of our research carried out over 10 years with the support of students, and Moldovan citizens, from the master's degree program "Romanian language - identity and cultural awareness." We present here a retrospective insight of the reforms, laws, and regulations that contributed to the shifted status of the Romanian language from the official language, seen as the language of common use both in the public and private spheres, in the minority language that surrendered its privileged place to the Russian language, firstly in the public sphere, and then, slowly but surely, in the private sphere. Our main goal here is to identify and make speakers understand what the barriers to learning Romanian language are nowadays when the social pressure on using Russian no longer exists. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=linguistic%20barriers" title="linguistic barriers">linguistic barriers</a>, <a href="https://publications.waset.org/abstracts/search?q=lingua%20franca" title=" lingua franca"> lingua franca</a>, <a href="https://publications.waset.org/abstracts/search?q=private%20sphere" title=" private sphere"> private sphere</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20sphere" title=" public sphere"> public sphere</a>, <a href="https://publications.waset.org/abstracts/search?q=reformation" title=" reformation"> reformation</a> </p> <a href="https://publications.waset.org/abstracts/151966/retrospective-insight-on-the-changing-status-of-the-romanian-language-spoken-in-the-republic-of-moldova" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151966.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">115</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">355</span> The Effect of Geometrical Ratio and Nanoparticle Reinforcement on the Properties of Al-based Nanocomposite Hollow Sphere Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Amirjan">Mostafa Amirjan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present study, the properties of Al-Al2O3 nanocomposite hollow sphere structures were investigated. For this reason, the Al-based nanocomposite hollow spheres with different amounts of nano alumina reinforcement (0-10wt %) and different ratio of thickness to diameter (t/D: 0.06-0.3) were prepared via a powder metallurgy method. Then, the effect of mentioned parameters was studied on physical and quasi static mechanical properties of their related prepared structures (open/closed cell) such as density, hardness, strength and energy absorption. It was found that as the t/D ratio increases the relative density, compressive strength and energy absorption increase. The highest values of strength and energy absorption were obtained from the specimen with 5 wt. % of nanoparticle reinforcement, t/D of 0.3 (t=1 mm, D=400µm) as 22.88 MPa and 13.24 MJ/m3, respectively. The moderate specific strength of prepared composites in the present study showed the good consistency with the properties of others low carbon steel composite with similar structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hollow%20sphere%20structure%20foam" title="hollow sphere structure foam">hollow sphere structure foam</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposite" title=" nanocomposite"> nanocomposite</a>, <a href="https://publications.waset.org/abstracts/search?q=thickness%20and%20diameter%20%28t%2FD%20%29" title=" thickness and diameter (t/D )"> thickness and diameter (t/D )</a>, <a href="https://publications.waset.org/abstracts/search?q=powder%20metallurgy" title=" powder metallurgy"> powder metallurgy</a> </p> <a href="https://publications.waset.org/abstracts/34507/the-effect-of-geometrical-ratio-and-nanoparticle-reinforcement-on-the-properties-of-al-based-nanocomposite-hollow-sphere-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34507.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">453</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">354</span> A Word-to-Vector Formulation for Word Representation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Rizkallah">Sandra Rizkallah</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20F.%20Atiya"> Amir F.

Embedding the vectors into a sphere enabled us to take into consideration the antonymity between words, not only the synonymity, because of the suitability to handle the polarity nature of words. For example, a word and its antonym can be represented as a vector and its negative. Moreover, we have managed to extract an adequate vocabulary.

The magnetic levitation system is a challenging nonlinear mechatronic system in which an electromagnetic force is required to suspend an object (metal sphere) in air space. The electromagnetic force is very sensitive to the noise which can create acceleration forces on the metal sphere, causing the sphere to move into the unbalanced region. Maglev’s give the contribution in industry and this system has reduce the power consumption, has increase the power efficiency and reduce the cost maintenance. The common applications for Maglev’s Power Generation (e.g. wind turbine), Maglev’s trains and Medical Device (e.g. Magnetically suspended Artificial Heart Pump).

The combination of carbon-based material and transition metal oxides/sulfides are studied because they have long and improved cycle life as well as high energy and power densities. In this study, a hierarchical mesoporous carbon sphere/nickel cobalt sulfide (CS/Ni-Co-S) core/shell structure was synthesized using a facile hydrothermal method without any further sulfurization or post-heat treatment. The CS/Ni-Co-S core/shell microstructures exhibited a high capacitance of 724 F g−1 at 2 A g−1 in a 6 M KOH electrolyte. After 2000 charge-discharge cycles, it retained 86.1% of its original capacitance, with high Coulombic efficiency of 97.9%. The electrode exhibited a high energy density of 58.0 Wh kg−1 at an energy density of 1440 W kg−1, and high power density of 7200 W kg−1 at an energy density of 34.2 Wh kg−1. The successful synthesis was considered to be simple and cost-effective which supports the viability of this composite as an alternative activated material for high performance supercapacitors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20sphere" title="carbon sphere">carbon sphere</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical" title=" electrochemical"> electrochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrothermal" title=" hydrothermal"> hydrothermal</a>, <a href="https://publications.waset.org/abstracts/search?q=nickel%20cobalt%20sulfide" title=" nickel cobalt sulfide"> nickel cobalt sulfide</a>, <a href="https://publications.waset.org/abstracts/search?q=supercapacitor" title=" supercapacitor"> supercapacitor</a> </p> <a href="https://publications.waset.org/abstracts/42938/hydrothermal-synthesis-of-carbon-spherenickel-cobalt-sulfide-coreshell-microstructure-and-its-electrochemical-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42938.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">303</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">350</span> The Amorphousness of the Exposure Sphere</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nipun%20Ansal">Nipun Ansal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> People guard their beliefs and opinions with their lives. Beliefs that they’ve formed over a period of time, and can go to any lengths to defy, desist from, resist and negate any outward stimulus that has the potential to shake them. Cognitive dissonance is term used to describe it in theory. And every human being, in order to defend himself from cognitive dissonance applies 4 rings of defense viz. Selective Exposure, Selective Perception, Selective Attention, and Selective Retention. This paper is a discursive analysis on how the onslaught of social media, complete with its intrusive weaponry, has amorphized the external ring of defense: the selective exposure. The stimulus-response model of communication is one of the most inherent model that encompasses communication behaviours of children and elderly, individual and masses, humans and animals alike. The paper deliberates on how information bombardment through the uncontrollable channels of the social media, Facebook and Twitter in particular, have dismantled our outer sphere of exposure, leading users online to a state of constant dissonance, and thus feeding impulsive action-taking. It applies case study method citing an example to corroborate how knowledge generation has given in to the information overload and the effect it has on decision making. With stimulus increasing in number of encounters, opinion formation precedes knowledge because of the increased demand of participation and decrease in time for the information to permeate from the outer sphere of exposure to the sphere of retention, which of course, is through perception and attention. This paper discusses the challenge posed by this fleeting, stimulus rich, peer-dominated media on the traditional models of communication and meaning-generation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=communication" title="communication">communication</a>, <a href="https://publications.waset.org/abstracts/search?q=discretion" title=" discretion"> discretion</a>, <a href="https://publications.waset.org/abstracts/search?q=exposure" title=" exposure"> exposure</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20media" title=" social media"> social media</a>, <a href="https://publications.waset.org/abstracts/search?q=stimulus" title=" stimulus"> stimulus</a> </p> <a href="https://publications.waset.org/abstracts/27309/the-amorphousness-of-the-exposure-sphere" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27309.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">408</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">349</span> Ethical Challenges for Journalists in Times of Fake News and Hate Speech: A Survey with German Journalists</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laura%20C.%20Solzbacher">Laura C.

Because of massive changes in media technology and the public sphere, especially online journalism has trouble to uphold the fundamental values of journalism. In particular, the increasing amount of fake news and hate speech puts journalists under more and more pressure. In order to understand better how journalists judge this development and how they adapt in their daily work, a survey with journalists in Germany was carried out. 303 professional journalists participated in an online questionnaire. Results show that 65% underline that economic pressure grows and nearly the same number describe a change in the role of journalists in society. Furthermore, 61% agree that they put more time into research to secure their work against accusations of fabricating fake news. Interestingly, over 60% see a change in the role of journalists in society. The majority (85%) confirms that print journalism has to give way for online platforms and that the influence of social media for journalism grows (75%). Half of the surveyed advocate for more personalized public activism on part of journalists, such as appearance in talk shows and public talks. The results of the study will be discussed in light of the ongoing debate on ethical standards as a condition for a sustainable and trustworthy digital public sphere. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ethics" title="ethics">ethics</a>, <a href="https://publications.waset.org/abstracts/search?q=fake%20news" title=" fake news"> fake news</a>, <a href="https://publications.waset.org/abstracts/search?q=journalism" title=" journalism"> journalism</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20sphere" title=" public sphere"> public sphere</a> </p> <a href="https://publications.waset.org/abstracts/92934/ethical-challenges-for-journalists-in-times-of-fake-news-and-hate-speech-a-survey-with-german-journalists" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92934.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">269</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">348</span> Morphology of the Acetabular Cartilage Surface in Elderly Cadavers Analyzing the Contact between the Acetabulum and Femoral Head</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Keisuke%20Akiyama">Keisuke Akiyama</a>, <a href="https://publications.waset.org/abstracts/search?q=Takashi%20Sakai"> Takashi Sakai</a>, <a href="https://publications.waset.org/abstracts/search?q=Junichiro%20Koyanagi"> Junichiro Koyanagi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hideki%20Yoshikawa"> Hideki Yoshikawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Kazuomi%20Sugamoto"> Kazuomi Sugamoto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The geometry of acetabular cartilage surface plays an important role in hip joint biomechanics. The aim of this study was to analyze the morphology of acetabular articular cartilage surface in elderly subjects using a 3D-digitizer. Twenty hemipelves from 12 subjects (mean ages 85 years) were scanned with 3D-digitizer. Each acetabular surface model was divided into four regions: anterosuperior (AS), anteroinferior (AI), posterosuperior (PS), and posteroinferior (PI). In the global acetabulum and each region, the acetabular sphere radius and the standard deviation (SD) of the distance from the acetabular sphere center to the acetabular cartilage surface were calculated. In the global acetabulum, the distance between the acetabular surface model and the maximum sphere which did not penetrate over the acetabular surface model was calculated as the inferred femoral head, and then the distribution was mapped at intervals of 0.5 mm. The SD in AS was significantly larger than that in AI (p = 0.006) and PI (p = 0.001). The SD in PS was significantly larger than that in PI (p = 0.005). The closest region (0-0.5 mm) tended to be distributed at anterior or posterosuperior acetabular edge. The contact between the femoral head and acetabulum might start at the periphery of the lunate surface, especially in the anterior or posterosuperior region. From viewpoint of acetabular morphology, the acetabular articular cartilage in the anterior or posterosuperior edge could be more vulnerable due to direct contact mechanism. <p
