system industry in many developing and developed countries has gone through a restructuring process of the industry where they are moving towards a deregulated power industry. This situation will lead to competition among the generation and distribution companies to achieve a certain objective which is to provide quality and efficient production of electric energy, which will reduce the price of electricity. Therefore it is important to obtain an accurate value of the Available Transfer Capability (ATC) and Transmission Reliability Margin (TRM) in order to ensure the effective power transfer between areas during the occurrence of uncertainties in the system. In this paper, the TRM and ATC is determined by taking into consideration the uncertainties of the system operating condition and system cascading collapse by applying the bootstrap technique. A case study of the IEEE RTS-79 is employed to verify the robustness of the technique proposed in the determination of TRM and ATC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=available%20transfer%20capability" title="available transfer capability">available transfer capability</a>, <a href="https://publications.waset.org/abstracts/search?q=bootstrap%20technique" title=" bootstrap technique"> bootstrap technique</a>, <a href="https://publications.waset.org/abstracts/search?q=cascading%20collapse" title=" cascading collapse"> cascading collapse</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20reliability%20margin" title=" transmission reliability margin"> transmission reliability margin</a> </p> <a href="https://publications.waset.org/abstracts/4347/evaluation-of-transfer-capability-considering-uncertainties-of-system-operating-condition-and-system-cascading-collapse" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4347.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">409</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> The Impact of System Cascading Collapse and Transmission Line Outages to the Transfer Capability Assessment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nur%20Ashida%20Salim">Nur Ashida Salim</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Murtadha%20Othman"> Muhammad Murtadha Othman</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Musirin"> Ismail Musirin</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Salleh%20Serwan"> Mohd Salleh Serwan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Uncertainty of system operating conditions is one of the causative reasons which may render to the instability of a transmission system. This will encumber the performance of transmission system to efficiently transmit the electrical power between areas. For that reason, accurate assessment of Transmission Reliability Margin (TRM) is essential in order to ensure effective power transfer between areas during the occurrence of system uncertainties. The power transfer is also called as the Available Transfer Capability (ATC) in which it is the information required by the utilities and marketers to instigate selling and buying the electric energy. This paper proposes a computationally effective approach to estimate TRM and ATC by considering the uncertainties of system cascading collapse and transmission line outages which is identified as the main reasons in power system instability. In accordance to the results that have been obtained, the proposed method is essential for the transmission providers which could help the power marketers and planning sectors in the operation and reserving transmission services based on the ATC calculated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=system%20cascading%20collapse" title="system cascading collapse">system cascading collapse</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20line%20outages" title=" transmission line outages"> transmission line outages</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20reliability%20margin" title=" transmission reliability margin"> transmission reliability margin</a>, <a href="https://publications.waset.org/abstracts/search?q=available%20transfer%20capability" title=" available transfer capability"> available transfer capability</a> </p> <a href="https://publications.waset.org/abstracts/4349/the-impact-of-system-cascading-collapse-and-transmission-line-outages-to-the-transfer-capability-assessment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4349.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">426</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">73</span> A New Approach to Retrofit Steel Moment Resisting Frame Structures after Mainshock</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20H.%20Farivarrad">Amir H.

To show the efficacy of the proposed method, a case study nine story steel moment frame building is chosen which was designed to pre-Northridge codes. The collapse fragility curve for the aftershock is presented for both the retrofitted and non-retrofitted structures.

Such a deformation is mathematically introduced as a particular type of noncommutativity between the canonical momenta of the scale factor and of the scalar field. In the absence of such deformation, the collapse culminates in a spacetime singularity. However, when the phase-space is deformed, we find that the singularity is removed by a non-singular bounce, beyond which the collapsing cloud re-expands to infinity. More precisely, for negative values of the deformation parameter, we identify the appearance of a negative pressure, which decelerates the collapse to finally avoid the singularity formation. While in the un-deformed case, the horizon curve monotonically decreases to finally cover the singularity, in the deformed case the horizon has a minimum value that this value depends on deformation parameter and initial configuration of the collapse. Such a setting predicts a threshold mass for black hole formation in stellar collapse and manifests the role of non-commutative geometry in physics and especially in stellar collapse and supernova explosion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gravitational%20collapse" title="gravitational collapse">gravitational collapse</a>, <a href="https://publications.waset.org/abstracts/search?q=non-commutative%20geometry" title=" non-commutative geometry"> non-commutative geometry</a>, <a href="https://publications.waset.org/abstracts/search?q=spacetime%20singularity" title=" spacetime singularity"> spacetime singularity</a>, <a href="https://publications.waset.org/abstracts/search?q=black%20hole%20physics" title=" black hole physics"> black hole physics</a> </p> <a href="https://publications.waset.org/abstracts/52267/non-singular-gravitational-collapse-of-a-homogeneous-scalar-field-in-deformed-phase-space" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52267.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">71</span> Evaluation of Progressive Collapse of Transmission Tower</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeong-Hwan%20Choi">Jeong-Hwan Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyo-Sang%20Park"> Hyo-Sang Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae-Hyung%20Lee"> Tae-Hyung Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The transmission tower is one of the crucial lifeline structures in a modern society, and it needs to be protected against extreme loading conditions. However, the transmission tower is a very complex structure and, therefore, it is very difficult to simulate the actual damage and the collapse behavior of the tower structure. In this study, the actual collapse behavior of the transmission tower due to lateral loading conditions such as wind load is evaluated through the computational simulation. For that, a progressive collapse procedure is applied to the simulation. In this procedure, after running the simulation, if a member of the tower structure fails, the failed member is removed and the simulation run again. The 154kV transmission tower is selected for this study. The simulation is performed by nonlinear static analysis procedure, namely pushover analysis, using OpenSEES, an earthquake simulation platform. Three-dimensional finite element models of those towers are developed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transmission%20tower" title="transmission tower">transmission tower</a>, <a href="https://publications.waset.org/abstracts/search?q=OpenSEES" title=" OpenSEES"> OpenSEES</a>, <a href="https://publications.waset.org/abstracts/search?q=pushover" title=" pushover"> pushover</a>, <a href="https://publications.waset.org/abstracts/search?q=progressive%20collapse" title=" progressive collapse"> progressive collapse</a> </p> <a href="https://publications.waset.org/abstracts/56404/evaluation-of-progressive-collapse-of-transmission-tower" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56404.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">357</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> Investigation of the Progressive Collapse Potential in Steel Buildings with Composite Floor System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pouya%20Kaafi">Pouya Kaafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Gholamreza%20Ghodrati%20Amiri"> Gholamreza Ghodrati Amiri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Abnormal loads due to natural events, implementation errors and some other issues can lead to occurrence of progressive collapse in structures. Most of the past researches consist of 2- Dimensional (2D) models of steel frames without consideration of the floor system effects, which reduces the accuracy of the modeling. While employing a 3-Dimensional (3D) model and modeling the concrete slab system for the floors have a crucial role in the progressive collapse evaluation. In this research, a 3D finite element model of a 5-story steel building is modeled by the ABAQUS software once with modeling the slabs, and the next time without considering them. Then, the progressive collapse potential is evaluated. The results of the analyses indicate that the lack of the consideration of the slabs during the analyses, can lead to inaccuracy in assessing the progressive failure potential of the structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abnormal%20loads" title="abnormal loads">abnormal loads</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20floor%20system" title=" composite floor system"> composite floor system</a>, <a href="https://publications.waset.org/abstracts/search?q=intermediate%20steel%20moment%20resisting%20frame%20system" title=" intermediate steel moment resisting frame system"> intermediate steel moment resisting frame system</a>, <a href="https://publications.waset.org/abstracts/search?q=progressive%20collapse" title=" progressive collapse"> progressive collapse</a> </p> <a href="https://publications.waset.org/abstracts/8692/investigation-of-the-progressive-collapse-potential-in-steel-buildings-with-composite-floor-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8692.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">456</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">69</span> An Improved Tie Force Method for Progressive Collapse Resistance Design of Precast Concrete Cross Wall Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Tohidi">M.

The tie force (TF) method is one of the main design approaches for progressive collapse. As the TF method is a simplified method, further investigations on the reliability of the method is necessary. This study aims to develop an improved TF method to design the cross wall structures for progressive collapse. To this end, the pullout behavior of strands in grout was firstly analyzed; and then, by considering the tie force-slip relationship in the friction stage together with the catenary action mechanism, a comprehensive analytical method was developed. The reliability of this approach is verified by the experimental results of concrete block pullout tests and full scale floor-to-floor joints tests undertaken by Portland Cement Association (PCA). Discrepancies in the tie force between the analytical results and codified specifications have suggested the deficiency of TF method, hence an improved model based on the analytical results has been proposed to address this concern. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross%20wall" title="cross wall">cross wall</a>, <a href="https://publications.waset.org/abstracts/search?q=progressive%20collapse" title=" progressive collapse"> progressive collapse</a>, <a href="https://publications.waset.org/abstracts/search?q=ties%20force%20method" title=" ties force method"> ties force method</a>, <a href="https://publications.waset.org/abstracts/search?q=catenary" title=" catenary"> catenary</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical" title=" analytical"> analytical</a> </p> <a href="https://publications.waset.org/abstracts/1653/an-improved-tie-force-method-for-progressive-collapse-resistance-design-of-precast-concrete-cross-wall-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1653.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">469</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">68</span> Collapse Performance of Steel Frame with Hysteric Energy Dissipating Devices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyung-Joon%20Kim">Hyung-Joon Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin-Young%20Park"> Jin-Young Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Energy dissipating devices (EDDs) have become more popular as seismic-force-resisting systems for building structures.

Nonlinear dynamic time history analysis of the 2D and 3D model structures are carried out based on the arbitrary column removal scenario, and the vertical displacement of the damaged structures are compared with that obtained from collision analysis. The analysis results show that the model structure remains stable when the speed of the vehicle is 40km/h.

The vertical displacement of the damaged joint obtained from collision analysis is significantly larger than the displacement computed based on the arbitrary column removal scenario. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vehicle%20collision" title="vehicle collision">vehicle collision</a>, <a href="https://publications.waset.org/abstracts/search?q=progressive%20collapse" title=" progressive collapse"> progressive collapse</a>, <a href="https://publications.waset.org/abstracts/search?q=FEM" title=" FEM"> FEM</a>, <a href="https://publications.waset.org/abstracts/search?q=LS-DYNA" title=" LS-DYNA"> LS-DYNA</a> </p> <a href="https://publications.waset.org/abstracts/52101/behavior-of-steel-moment-frames-subjected-to-impact-load" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52101.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">342</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> Seismic Performance of Reinforced Concrete Frames Infilled by Masonry Walls with Different Heights</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ji-Wook%20Mauk">Ji-Wook Mauk</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Suk%20Kim"> Yu-Suk Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyung-Joon%20Kim"> Hyung-Joon Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study carried out comparative seismic performance of reinforced concrete frames infilled by masonry walls with different heights. Partial and fully infilled RC frames were modeled for the research objectives and the analysis model for a bare reinforced concrete frame was established for comparison. Non-linear static analyses for the studied frames were performed to investigate their structural behavior under extreme loading conditions and to find out their collapse mechanism. It was observed from analysis results that the strengths of the partial infilled RC frames are increased and their ductility is reduced, as infilled masonry walls are higher. Especially, Reinforced concrete frames with a higher partial infilled masonry wall would experience shear failures. Non-linear dynamic analyses using 10 earthquake records show that the bare and fully infilled reinforced concrete frames present stable collapse mechanism while the reinforced concrete frames with a partially infilled masonry wall collapse in more brittle manner due to short-column effects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fully%20infilled%20RC%20frame" title="fully infilled RC frame">fully infilled RC frame</a>, <a href="https://publications.waset.org/abstracts/search?q=partially%20infilled%20RC%20frame" title=" partially infilled RC frame"> partially infilled RC frame</a>, <a href="https://publications.waset.org/abstracts/search?q=masonry%20wall" title=" masonry wall"> masonry wall</a>, <a href="https://publications.waset.org/abstracts/search?q=short-column%20effect" title=" short-column effect"> short-column effect</a> </p> <a href="https://publications.waset.org/abstracts/21654/seismic-performance-of-reinforced-concrete-frames-infilled-by-masonry-walls-with-different-heights" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21654.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">422</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> DG Power Plants Placement and Evaluation of its Effect on Improving Voltage Security Margin in Radial Distribution Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atabak%20Faramarzpour">Atabak Faramarzpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Mohammadian"> Mohsen Mohammadian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article, we introduce the stability of power system voltage and state DG power plants placement and its effect on improving voltage security margin in radial distribution networks.

In particular, we focus on neo-Hookean class of models and represent them using an invariant-free formulation. To achieve this, we revise the invariant-free formulation of isotropic hyperelasticity. The formulation uses quadruple contractions between fourth-order tensors, rather than scalar products of scalar invariants. We also propose a new decomposition of the orthotropic Hookean stiffness tensor into two fourth-order Lamé tensors that collapse down to the classic Lamé parameters for isotropic continua. The resulting orthotropic hyperelastic model naturally maintains all of the advanced properties of the isotropic counterparts, and similarly collapse back down to their isotropic form by nothing more than equality of parameters in all directions (isotropy).

However, limited studies are available when this type of structure is subjected to impact or explosive loads. Current methods in relevant design codes are not specific for preventing progressive collapse of CFST structures. Therefore, it is necessary to carry out numerical simulations on CFST structure under impact loads. In this study, finite element analyses are conducted on the mechanical behaviour of composite frames which composed of CFST columns and steel beams subject to impact loading. In the model, CFST columns are simulated using finite element software ABAQUS. The model is verified by test results of solid and hollow CFST columns under lateral impacts, and reasonably good agreement is obtained through comparisons. Thereafter, a multi-scale finite element modelling technique is developed to evaluate the behaviour of a five-storey three-span planar composite frame. Alternate path method and direct simulation method are adopted to perform the dynamic response of the frame when a supporting column is removed suddenly. In the former method, the reason for column removal is not considered and only the remaining frame is simulated, whereas in the latter, a specific impact load is applied to the frame to take account of the column failure induced by vehicle impact. Comparisons are made between these two methods in terms of displacement history and internal force redistribution, and design recommendations are provided for the design of CFST structures under impact loads. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=planar%20composite%20frame" title="planar composite frame">planar composite frame</a>, <a href="https://publications.waset.org/abstracts/search?q=collapse%20analysis" title=" collapse analysis"> collapse analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20loading" title=" impact loading"> impact loading</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20simulation%20method" title=" direct simulation method"> direct simulation method</a>, <a href="https://publications.waset.org/abstracts/search?q=alternate%20path%20method" title=" alternate path method"> alternate path method</a> </p> <a href="https://publications.waset.org/abstracts/66231/collapse-analysis-of-planar-composite-frame-under-impact-loads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66231.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">519</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> A Novel Method for Live Debugging of Production Web Applications by Dynamic Resource Replacement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khalid%20Al-Tahat">Khalid Al-Tahat</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Zuhair%20Mahmoud%0F"> Khaled Zuhair Mahmoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Al-Mughrabi"> Ahmad Al-Mughrabi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes a novel methodology for enabling debugging and tracing of production web applications without affecting its normal flow and functionality.

Is mathematical formalism of wavefunction correct? Does wavefunction collapse during measurement? Do quantum physical entanglement and many world interpretations really exist? In addition, is there uncertainty in the physical reality of our nature as being concluded in the Quantum theory? We have been able to show by the fundamental analysis presented in this work that the way quantum mechanics theory, and interpretation describes nature is not correlated with physical reality. Because, we discovered amongst others that, (1) Guided energy theory of a particle fundamentally provides complete physical observable series of quantized measurement of a particle momentum, force, energy e.t.c. in a given distance and time.In contrast, quantum mechanics wavefunction describes that nature has inherited probabilistic and indeterministic physical quantities, resulting in unobservable physical quantities that lead to many worldinterpretation.(2) Guided energy theory of a particle fundamentally predicts that it is mathematically possible to determine precise quantized measurementof position and momentum of a particle simultaneously. Because, there is no uncertainty in nature; nature however naturally guides itself against uncertainty. Contrary to the conclusion in quantum mechanics theory that, it is mathematically impossible to determine the position and the momentum of a particle simultaneously. Furthermore, we have been able to show by this theory that, it is mathematically possible to determine quantized measurement of force acting on a particle simultaneously, which is not possible on the premise of quantum mechanics theory. (3) It is evidently shown by our theory that, guided energy does not collapse, only describes the lopsided nature of a particle behavior in motion. This pretty offers us insight on gradual process of engagement - convergence and disengagement – divergence of guided energy holders which further highlight the picture how wave – like behavior return to particle-like behavior and how particle – like behavior return to wave – like behavior respectively. This further proves that the particles’ behavior in motion is oscillatory in nature. The mathematical formalism of Guided energy theory shows that nature is certainty whereas the mathematical formalism of Quantum mechanics theory shows that nature is absolutely probabilistics. In addition, the nature of wavefunction is the guided energy of the wave. In conclusion, the fundamental mathematical formalism of Quantum mechanics theory is wrong. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=momentum" title="momentum">momentum</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20entanglement" title=" physical entanglement"> physical entanglement</a>, <a href="https://publications.waset.org/abstracts/search?q=wavefunction" title=" wavefunction"> wavefunction</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertainty" title=" uncertainty"> uncertainty</a> </p> <a href="https://publications.waset.org/abstracts/72416/guided-energy-theory-of-a-particle-answered-questions-arise-from-quantum-foundation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72416.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">295</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">56</span> Honey Intoxication: A Unique Cause of Sudden Cardiac Collapse</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bharat%20Rawat">Bharat Rawat</a>, <a href="https://publications.waset.org/abstracts/search?q=Shekhar%20Rajbhandari"> Shekhar Rajbhandari</a>, <a href="https://publications.waset.org/abstracts/search?q=Yadav%20Bhatta"> Yadav Bhatta</a>, <a href="https://publications.waset.org/abstracts/search?q=Jay%20Prakash%20Jaiswal"> Jay Prakash Jaiswal</a>, <a href="https://publications.waset.org/abstracts/search?q=Shivaji%20Bikram%20Silwal"> Shivaji Bikram Silwal</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajiv%20Shrestha"> Rajiv Shrestha</a>, <a href="https://publications.waset.org/abstracts/search?q=Shova%20Sunuwar"> Shova Sunuwar </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The honey produced by the bees fed on Rhobdodendron species containing grayanotoxin is known as mad honey. Grayanotoxin is found in honey obtained from the nectar of Rhododendron species growing on the mountains of the Black Sea region of Turkey and also in Japan, Nepal, Brazil, parts of North America, and Europe. Although the incidence of grayanotoxin poisoning is rare, there is concern that the number of cases per year will rise with the increasing demand for organic products. Mad honey intoxication might present with mild symptoms of cardiovascular, gastrointestinal and neurological systems or might also present with a life-threatening form with AV block and cardiovascular collapse. In this article, we describe the summary of five cases, which came to our hospital with mad honey related cardiac complications. Findings: In last one year, five cases presented in the emergency department with sudden onset of Loss of consciousness, dizziness, shortness of breath. They felt difficulty after the consumption of 1-3 teaspoonful of wild honey. The honey was brought from most of the rural parts of Nepal like khotang. Some of them also came with vomiting, dizziness, and loose stool. On examination, most of them had severe bradycardia and low blood pressure. No abnormalities were detected on systemic examinations. In one patient, ECG and cardiac enzymes showed features of the acute coronary syndrome, but his treadmill test done few days later was normal. All patients were managed with inj. Atropine, I/V normal saline, and other supportive measures and discharged in a stable condition within one or two days. Conclusions: Rhododendrons is the national flower of Nepal. The specific species of rhododendron found in Nepal which contains the toxin is not known. Bees feeding on these rhododendrons are known to transfer the grayanotoxin to the honey they produce. Most symptoms are mild and resolve themselves without medical intervention. Signs and symptoms of grayanotoxin poisoning rarely last more than 24 hours and are usually not fatal. Some signs of mad honey poisoning include Bradycardia, Cardiac arrhythmia, Hypotension, Nausea and Vomiting. They respond to close monitoring and appropriate supportive treatment. Normally, patients recover completely with no residual damage to the heart or its conduction system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rhobdodendron" title="rhobdodendron">rhobdodendron</a>, <a href="https://publications.waset.org/abstracts/search?q=honey" title=" honey"> honey</a>, <a href="https://publications.waset.org/abstracts/search?q=grayanotoxin" title=" grayanotoxin"> grayanotoxin</a>, <a href="https://publications.waset.org/abstracts/search?q=bradycardia" title=" bradycardia"> bradycardia</a> </p> <a href="https://publications.waset.org/abstracts/31998/honey-intoxication-a-unique-cause-of-sudden-cardiac-collapse" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31998.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">348</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> A Review on Concrete Structures in Fire</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Iffat">S.

Concrete’s inherent ability to combat one of the most devastating disaster that a structure can endure in its lifetime, can be attributed to its constituent materials which make it inert and have relatively poor thermal conductivity. However, concrete structures must be designed for fire effects. Structural components should be able to withstand dead and live loads without undergoing collapse. The properties of high-strength concrete must be weighed against concerns about its fire resistance and susceptibility to spalling at elevated temperatures. In this paper, the causes, effects and some remedy of deterioration in concrete due to fire hazard will be discussed. Some cost effective solutions to produce a fire resistant concrete will be conversed through this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete" title="concrete">concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=fire" title=" fire"> fire</a>, <a href="https://publications.waset.org/abstracts/search?q=spalling" title=" spalling"> spalling</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=density" title=" density"> density</a> </p> <a href="https://publications.waset.org/abstracts/41154/a-review-on-concrete-structures-in-fire" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41154.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">443</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> Data-Driven Analysis of Velocity Gradient Dynamics Using Neural Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nishant%20Parashar">Nishant Parashar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sawan%20S.%20Sinha"> Sawan S.

Velocity gradients in a compressible turbulent flow field influence several important nonlinear turbulent processes like cascading and intermittency. In an attempt to understand the dynamics of the velocity gradients various researchers have tried to model the unclosed terms in the evolution equation of the VGT. The existing models proposed for these unclosed terms have limited applicability. This is mainly attributable to the complex structure of the higher order gradient terms appearing in the evolution equation of VGT. We investigate these higher order gradients using the data from direct numerical simulation (DNS) of compressible decaying isotropic turbulent flow. The gas kinetic method aided with weighted essentially non-oscillatory scheme (WENO) based flow- reconstruction is employed to generate DNS data. By applying neural-network to the DNS data, we map the structure of the unclosed higher order gradient terms in the evolution of the equation of the VGT with VGT itself. We validate our findings by performing alignment based study of the unclosed higher order gradient terms obtained using the neural network with the strain rate eigenvectors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compressible%20turbulence" title="compressible turbulence">compressible turbulence</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20network" title=" neural network"> neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=velocity%20gradient%20tensor" title=" velocity gradient tensor"> velocity gradient tensor</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20numerical%20simulation" title=" direct numerical simulation"> direct numerical simulation</a> </p> <a href="https://publications.waset.org/abstracts/101552/data-driven-analysis-of-velocity-gradient-dynamics-using-neural-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101552.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">168</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> Assuming the Decision of Having One (More) Child: The New Dimensions of the Post Communist Romanian Family</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Horea-Serban%20Raluca-Ioana">Horea-Serban Raluca-Ioana</a>, <a href="https://publications.waset.org/abstracts/search?q=Istrate%20Marinela"> Istrate Marinela</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The first part of the paper analyzes the dynamics of the total fertility rate both at the national and regional level, pointing out the regional disparities in the distribution of this indicator.

To allow for the parallel removal of multiple vertices we use a set of per-vertex boundaries that prevent mesh foldovers even when simplification operations are performed on neighbouring vertices. We execute multiple iterations of the calculation of the vertex errors, ordering of the error values and removal of vertices until either a desired number of vertices remains in the mesh or a minimum error value is reached.

Today science intends to define concept of information and comprehend informations role and function in contemporary society. Organization of social environment and governance of public processes on the base of information and tools of communication are main characteristics of informational era. This was defined by technological changes which were accomplished in culture in the second half of twentieth century. Today Georgia as an independent state needs to create an informational discourse of the country and therefore it is very important to study political and social cases which accomplished in the country after collapse of the Soviet Union because they start to define the present and the future of the country. The purpose of this study is to analyze political cases of the latest history of Georgia in terms of culture and information, concretely to elucidate which political cases transformed social life of post Soviet Georgia most of all who accomplished these political cases which visual and verbal messages was each political case spread with. The research is conducted on the base of interview. Participants of the interview are people of various specializations. Their professional activity is related to reflections on culture and theme of visual communication. They are philosophers sociologists a journalist media researcher a politologist a painter. The participants of the interview enumerated political cases and characterized them separately. Every expert thinks that declaration of independence of Georgia is the most important fact among all facts which were implemented in Georgia after collapse of the Soviet Union. The research revealed important social and political cases. Most of the cases are related to independence and territorial integrity of the state. Presidents of Georgia Zviad Gamsakhurdia Eduard Shevardnadze Mikheil Saakashvili Catholocos-Patriarch of All Georgia, the Archbishop of Mtskheta Tbilisi and Metropolitan bishop of Bichvinta and Tskhum Abkhazia Ilia II, businessman Bidzina Ivanishvili assumed dominating roles in cases. Verbal narrative of the cases accomplished during Zviad Gamsakhurdia presidential term expresses national freedom and visual part of cases of the same period expresses ruin of social-political structure. Verbal narrative of the cases accomplished during Eduard Sevardnadze presidential term expresses Free State and stability and reestablishment of Georgias political function in international relations and visual part of cases of the same period describes the most important moment of his presidential term and Eduard Shevardnadzes face appears too. Verbal narrative of the cases accomplished during Mikheil Saakashvilis presidential term expresses social renewal and visual part of cases of the same period describes August war and Mikheil Saakashvilis face appears too. The results of the study also reveal other details of visual verbal narrative of political and social cases of post Soviet Georgia.

Apart from human casualty, the damage to built-up infrastructures like roads, bridges, buildings and other properties are the collateral episodes. The appropriate planning must precede with a view to safeguarding people’s welfare, infrastructures and other properties at a site based on proper evaluation and assessments of the potential level of earthquake hazard. The information or output results can be used as a tool that can assist in minimizing risk from earthquakes and also can foster appropriate construction design and formulation of building codes at a particular site. Different disciplines adopt different approaches in assessing and monitoring earthquake hazard throughout the world. For the present study, GIS and Remote Sensing potentials were utilized to evaluate and assess earthquake hazards of the study region. Subsurface geology and geomorphology were the common features or factors that were assessed and integrated within GIS environment coupling with seismicity data layers like; Peak Ground Acceleration (PGA), historical earthquake magnitude and earthquake depth to evaluate and prepare liquefaction potential zones (LPZ) culminating in earthquake hazard zonation of our study sites. The liquefaction can eventuate in the aftermath of severe ground shaking with amenable site soil condition, geology and geomorphology. The latter site conditions or the wave propagation media were assessed to identify the potential zones. The precept has been that during any earthquake event the seismic wave is generated and propagates from earthquake focus to the surface. As it propagates, it passes through certain geological or geomorphological and specific soil features, where these features according to their strength/stiffness/moisture content, aggravates or attenuates the strength of wave propagation to the surface. Accordingly, the resulting intensity of shaking may or may not culminate in the collapse of built-up infrastructures. For the case of earthquake hazard zonation, the overall assessment was carried out through integrating seismicity data layers with LPZ. Multi-criteria Evaluation (MCE) with Saaty’s Analytical Hierarchy Process (AHP) was adopted for this study. It is a GIS technology that involves integration of several factors (thematic layers) that can have a potential contribution to liquefaction triggered by earthquake hazard. The factors are to be weighted and ranked in the order of their contribution to earthquake induced liquefaction. The weightage and ranking assigned to each factor are to be normalized with AHP technique. The spatial analysis tools i.e., Raster calculator, reclassify, overlay analysis in ArcGIS 10 software were mainly employed in the study. The final output of LPZ and Earthquake hazard zones were reclassified to ‘Very high’, ‘High’, ‘Moderate’, ‘Low’ and ‘Very Low’ to indicate levels of hazard within a study region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hazard%20micro-zonation" title="hazard micro-zonation">hazard micro-zonation</a>, <a href="https://publications.waset.org/abstracts/search?q=liquefaction" title=" liquefaction"> liquefaction</a>, <a href="https://publications.waset.org/abstracts/search?q=multi%20criteria%20evaluation" title=" multi criteria evaluation"> multi criteria evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=tectonism" title=" tectonism"> tectonism</a> </p> <a href="https://publications.waset.org/abstracts/57539/gis-and-remote-sensing-approach-in-earthquake-hazard-assessment-and-monitoring-a-case-study-in-the-momase-region-of-papua-new-guinea" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57539.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">266</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">47</span> A Criterion for Evaluating Plastic Loads: Plastic Work-Tangent Criterion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ying%20Zhang">Ying Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In ASME Boiler and Pressure Vessel Code, the plastic load is defined by applying the twice elastic slope (TES) criterion of plastic collapse to a characteristic load-deformation curve for the vessel. Several other plastic criterion such as tangent intersection (TI) criterion, plastic work (PW) criterion have been proposed in the literature, but all exhibit a practical limitation: difficult to define the load parameter for vessels subject to several combined loads. An alternative criterion: plastic work-tangent (PWT) criterion for evaluating plastic load in pressure vessel design by analysis is presented in this paper. According to the plastic work-load curve, when the tangent variation is less than a given value in the plastic phase, the corresponding load is the plastic load. Application of the proposed criterion is illustrated by considering the elastic-plastic response of the lower head of reactor pressure vessel (RPV) and nozzle intersection of (RPV). It is proposed that this is because the PWT criterion more fully represents the constraining effect of material strain hardening on the spread of plastic deformation and more efficiently ton evaluating the plastic load. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plastic%20load" title="plastic load">plastic load</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20work" title=" plastic work"> plastic work</a>, <a href="https://publications.waset.org/abstracts/search?q=strain%20hardening" title=" strain hardening"> strain hardening</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20work-tangent%20criterion" title=" plastic work-tangent criterion"> plastic work-tangent criterion</a> </p> <a href="https://publications.waset.org/abstracts/59204/a-criterion-for-evaluating-plastic-loads-plastic-work-tangent-criterion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59204.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">355</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">46</span> Real-Time Compressive Strength Monitoring for NPP Concrete Construction Using an Embedded Piezoelectric Self-Sensing Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Junkyeong%20Kim">Junkyeong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Seunghee%20Park"> Seunghee Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Ju-Won%20Kim"> Ju-Won Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Myung-Sug%20Cho"> Myung-Sug Cho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, demands for the construction of Nuclear Power Plants (NPP) using high strength concrete (HSC) has been increased. However, HSC might be susceptible to brittle fracture if the curing process is inadequate. To prevent unexpected collapse during and after the construction of HSC structures, it is essential to confirm the strength development of HSC during the curing process. However, several traditional strength-measuring methods are not effective and practical. In this study, a novel method to estimate the strength development of HSC based on electromechanical impedance (EMI) measurements using an embedded piezoelectric sensor is proposed. The EMI of NPP concrete specimen was tracked to monitor the strength development. In addition, cross-correlation coefficient was applied in sequence to examine the trend of the impedance variations more quantitatively. The results confirmed that the proposed technique can be applied successfully monitoring of the strength development during the curing process of HSC structures. <p
