manifested itself as an art school in various aspects, including miniatures, architecture, urban planning and design, simultaneously with the expansion of the many sciences of its time. In this era, mysticism, both in form and in poetry and prose, as well as in works of art reached its peak. Mysticism, as an inner belief and thought, brought the audience to the artistic and aesthetical view using allegorical and symbolic expression of the religion and had a direct impact on the formation of the intellectual and cultural layers of the society. At the same time, Mystic school of Tabriz could create a symbolic and allegorical language to create magnificent works of architecture with the expansion of science in various fields and using various sciences such as mathematics, geometry, science of numbers and by Abjad letters. In this era, geometry is the middle link between mysticism and architecture and it is divided into two categories, including intellectual and sensory geometry and based on its function. Soltaniyeh dome is one of the prominent buildings of the Tabriz school with the shrine land use. In this article, information is collected using a historical-interpretive method and the results are analyzed using an analytical-comparative method. The results of the study suggest that the designers and builders of the Soltaniyeh dome have used shapes, colors, numbers, letters and words in the form of motifs, geometric patterns as well as lines and writings in levels and layers ranging from plans to decorations and arrays for architectural symbolization and encryption to express and transmit mystical ideas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geometry" title="geometry">geometry</a>, <a href="https://publications.waset.org/abstracts/search?q=Tabriz%20school" title=" Tabriz school"> Tabriz school</a>, <a href="https://publications.waset.org/abstracts/search?q=mystical%20thoughts" title=" mystical thoughts"> mystical thoughts</a>, <a href="https://publications.waset.org/abstracts/search?q=dome%20of%20Soltaniyeh" title=" dome of Soltaniyeh"> dome of Soltaniyeh</a> </p> <a href="https://publications.waset.org/abstracts/161320/geometry-the-language-of-manifestation-of-tabriz-schools-mystical-thoughts-in-architecture-case-study-dome-of-soltanieh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161320.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">86</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">43</span> On Strengthening Program of Sixty Years Old Dome Using Carbon Fiber</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Humayun%20R.%20H.%20Kabir">Humayun R.

It was decided to restore the dome to its full strength for future use. A full material strength and durability check including petrography test were conducted. It was observed that the concrete strength was in acceptable range, while bars were corroded more than 40% to their original configurations. Widespread cracks were almost in every meter square. A strengthening program with filling the cracks by injection method, and carbon fiber layup and wrap was considered. Ultra Sound Pulse Velocity (UPV) test was conducted to observe crack depth. Ground Penetration Radar (GPR) test was conducted to observe internal bar conditions and internal cracks. Finally, a load test was conducted to certify the carbon fiber effectiveness, injection method procedure and overall behavior of dome. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dome" title="dome">dome</a>, <a href="https://publications.waset.org/abstracts/search?q=strengthening%20program" title=" strengthening program"> strengthening program</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20fiber" title=" carbon fiber"> carbon fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20test" title=" load test"> load test</a> </p> <a href="https://publications.waset.org/abstracts/76188/on-strengthening-program-of-sixty-years-old-dome-using-carbon-fiber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76188.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">256</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">42</span> Assessment of the Energy Balance Method in the Case of Masonry Domes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20M.%20Sadeghi">M.

The seismic assessment of these historical structures is very complicated due to the nonlinear behavior of the material, their rigidness, and special stability configuration. The assessment method based on energy balance concept, as well as the standard pushover analysis, is used to evaluate the effectiveness of these methods in the case of masonry dome structures. The Soltanieh dome building is used as an example to which two methods are applied. The performance points are given from superimposing the capacity, and demand curves in Acceleration Displacement Response Spectra (ADRS) and energy coordination are compared with the nonlinear time history analysis as the exact result. The results show a good agreement between the dynamic analysis and the energy balance method, but standard pushover method does not provide an acceptable estimation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20balance%20method" title="energy balance method">energy balance method</a>, <a href="https://publications.waset.org/abstracts/search?q=pushover%20analysis" title=" pushover analysis"> pushover analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20history%20analysis" title=" time history analysis"> time history analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=masonry%20dome" title=" masonry dome"> masonry dome</a> </p> <a href="https://publications.waset.org/abstracts/58811/assessment-of-the-energy-balance-method-in-the-case-of-masonry-domes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58811.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">281</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">41</span> Between an Idea and the Experiment: Dome Houses in Warsaw</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zagu%C5%82a%20Artur">Zaguła Artur</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaruga-rozdolska%20Anna"> Jaruga-rozdolska Anna</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The idea of prefabricated dwellings dates back to the earliest times; however, it was during the modern era that it became one of the main thoughts that stimulated the imagination of architects. The system of prefabrication invented by Ford had inspired them to try to create a system or prototype that could become the basis for the mass 'production' of houses. The attempts made by Le Corbusier, Buckminster Fuller or Charles and Ray Eames, among others, are well known in this regard. The economic attractiveness of replicable, mass-producible houses meant that experiments in this area were undertaken in both the West and the East. Among such attempts was the project of dome-shaped houses conceived by the architect and inventor Andrzej Iwanicki and realised between 1961 and 1966 in Warsaw's Okęcie district on Ustrzycka Street. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dome%20houses" title="dome houses">dome houses</a>, <a href="https://publications.waset.org/abstracts/search?q=polish%20modernism" title=" polish modernism"> polish modernism</a>, <a href="https://publications.waset.org/abstracts/search?q=postwar%20modernism" title=" postwar modernism"> postwar modernism</a>, <a href="https://publications.waset.org/abstracts/search?q=modernist%20houses" title=" modernist houses"> modernist houses</a> </p> <a href="https://publications.waset.org/abstracts/167147/between-an-idea-and-the-experiment-dome-houses-in-warsaw" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167147.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">108</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">40</span> Formex Algebra Adaptation into Parametric Design Tools: Dome Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R%C3%A9ka%20S%C3%A1rk%C3%B6zi">Réka Sárközi</a>, <a href="https://publications.waset.org/abstracts/search?q=P%C3%A9ter%20Iv%C3%A1nyi"> Péter Iványi</a>, <a href="https://publications.waset.org/abstracts/search?q=Attila%20B.%20Sz%C3%A9ll"> Attila B.

Formex algebra is a mathematical system, primarily used for planning structural systems such like truss-grid domes and vaults, together with the programming language Formian. The goal of the research is to allow architects to plan truss-grid structures easily with parametric design tools based on the versatile formex algebra mathematical system. To produce regular structures, coordinate system transformations are used and the dome structures are defined in spherical coordinate system. Owing to the abilities of the parametric design software, it is possible to apply further modifications on the structures and gain special forms. The paper covers the basic dome types, and also additional dome-based structures using special coordinate-system solutions based on spherical coordinate systems. It also contains additional structural possibilities like making double layer grids in all geometry forms. The adaptation of formex algebra and the parametric workflow of Grasshopper together give the possibility of quick and easy design and optimization of special truss-grid domes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=parametric%20design" title="parametric design">parametric design</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20morphology" title=" structural morphology"> structural morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20structures" title=" space structures"> space structures</a>, <a href="https://publications.waset.org/abstracts/search?q=spherical%20coordinate%20system" title=" spherical coordinate system"> spherical coordinate system</a> </p> <a href="https://publications.waset.org/abstracts/82738/formex-algebra-adaptation-into-parametric-design-tools-dome-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82738.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">254</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">39</span> NextCovps: Design and Stress Analysis of Dome Composite Overwrapped Pressure Vessels using Geodesic Trajectory Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Maziz">Ammar Maziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Prateek%20Gupta"> Prateek Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Thiago%20Vasconcellos%20Birro"> Thiago Vasconcellos Birro</a>, <a href="https://publications.waset.org/abstracts/search?q=Benoit%20Gely"> Benoit Gely</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hydrogen as a sustainable fuel has the highest energy density per mass as compared to conventional non-renewable sources. As the world looks to move towards sustainability, especially in the sectors of aviation and automotive, it becomes important to address the issue of storage of hydrogen as compressed gas in high-pressure tanks. To improve the design for the efficient storage and transportation of Hydrogen, this paper presents the design and stress analysis of Dome Composite Overwrapped Pressure Vessels (COPVs) using the geodesic trajectory approach. The geodesic trajectory approach is used to optimize the dome design, resulting in a lightweight and efficient structure. Python scripting is employed to implement the mathematical modeling of the COPV, and after validating the model by comparison to the published paper, stress analysis is conducted using Abaqus commercial code. The results demonstrate the effectiveness of the geodesic trajectory approach in achieving a lightweight and structurally sound dome design, as well as the accuracy and reliability of the stress analysis using Abaqus commercial code. This study provides insights into the design and analysis of COPVs for aerospace applications, with the potential for further optimization and application in other industries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20overwrapped%20pressure%20vessels" title="composite overwrapped pressure vessels">composite overwrapped pressure vessels</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20fiber" title=" carbon fiber"> carbon fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=geodesic%20trajectory%20approach" title=" geodesic trajectory approach"> geodesic trajectory approach</a>, <a href="https://publications.waset.org/abstracts/search?q=dome%20design" title=" dome design"> dome design</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20analysis" title=" stress analysis"> stress analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=plugin%20python" title=" plugin python"> plugin python</a> </p> <a href="https://publications.waset.org/abstracts/167305/nextcovps-design-and-stress-analysis-of-dome-composite-overwrapped-pressure-vessels-using-geodesic-trajectory-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167305.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">92</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">38</span> Concept and Implementation of Religious Tourism as a City Icon; Case Study: Golden Dome Mosque in Depok, Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azhari%20Fauzan">Azhari Fauzan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dian Al Mahri Mosque or more known as Golden Dome Mosque is one of the biggest mosques in Southeast Asia which located in Depok, West Java Province, Indonesia.

One of the factors that shape the form of a dome is the geometric proportion used in the drawing and construction of the dome. Some commonly used proportions are revealed by analysing the shapes and geometric ratio of the monuments’ domes. The proportions are achieved by the proficiency of the skilled architects of the buildings. These proportions can be used to reconstruct damaged parts of the historical monuments. Most of the research on domes is about the historical or stability features of domes, and less attention is made to the geometric system in domes. Therefore, in this study, we study the explicit and implicit geometric proportions in Iranian dome structures for the first time. The study is done based on a literature review and field survey. This research reveals that the permanent geometric rules are perfectly used in the design and construction of the prominent domes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geometry%20in%20architecture" title="geometry in architecture">geometry in architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=architectural%20proportions" title=" architectural proportions"> architectural proportions</a>, <a href="https://publications.waset.org/abstracts/search?q=prominent%20domes" title=" prominent domes"> prominent domes</a>, <a href="https://publications.waset.org/abstracts/search?q=iranian%20golden%20ratio" title=" iranian golden ratio"> iranian golden ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=geometric%20proportion" title=" geometric proportion"> geometric proportion</a> </p> <a href="https://publications.waset.org/abstracts/149514/geometric-continuity-in-the-form-of-iranian-domes-study-of-prominent-safavid-and-sasanian-domes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149514.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">284</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">36</span> Sustainable Design for Building Envelope in Hot Climates: A Case Study for the Role of the Dome as a Component of an Envelope in Heat Exchange</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akeel%20Noori%20Almulla%20Hwaish">Akeel Noori Almulla Hwaish</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Architectural design is influenced by the actual thermal behaviour of building components, and this in turn depends not only on their steady and periodic thermal characteristics, but also on exposure effects, orientation, surface colour, and climatic fluctuations at the given location. Design data and environmental parameters should be produced in an accurate way for specified locations, so that architects and engineers can confidently apply them in their design calculations that enable precise evaluation of the influence of various parameters relating to each component of the envelope, which indicates overall thermal performance of building. The present paper will be carried out with an objective of thermal behaviour assessment and characteristics of the opaque and transparent parts of one of the very unique components used as a symbolic distinguished element of building envelope, its thermal behaviour under the impact of solar temperatures, and its role in heat exchange related to a specific U-value of specified construction materials alternatives. The research method will consider the specified Hot-Dry weather and new mosque in Baghdad, Iraq as a case study. Also, data will be presented in light of the criteria of indoor thermal comfort in terms of design parameters and thermal assessment for a“model dome”. Design alternatives and considerations of energy conservation, will be discussed as well using comparative computer simulations. Findings will be incorporated to outline the conclusions clarifying the important role of the dome in heat exchange of the whole building envelope for approaching an indoor thermal comfort level and further research in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building%20envelope" title="building envelope">building envelope</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20design" title=" sustainable design"> sustainable design</a>, <a href="https://publications.waset.org/abstracts/search?q=dome%20impact" title=" dome impact"> dome impact</a>, <a href="https://publications.waset.org/abstracts/search?q=hot-climates" title=" hot-climates"> hot-climates</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20exchange" title=" heat exchange"> heat exchange</a> </p> <a href="https://publications.waset.org/abstracts/27249/sustainable-design-for-building-envelope-in-hot-climates-a-case-study-for-the-role-of-the-dome-as-a-component-of-an-envelope-in-heat-exchange" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27249.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">475</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">35</span> Calculating Quantity of Steel Bar Placed in Mesh Form in a Circular Slab or Dome</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karam%20Chand%20Gupta">Karam Chand Gupta </a> </p> <p class="card-text"><strong>Abstract:</strong></p> When steel reinforcement is placed in mesh form in circular concrete slab at base or domes at top in case of over head service reservoir or any other structure, it is difficult to estimate/measure the total quantity of steel that would be needed or placed.

Metals sheets with varied thickness, strength and coatings are welded together to form TWBs through friction stir welding and laser welding prior to stamping operations. The formability of the TWBs completely varies from those of conventional blanks due to the diverse strength levels of individual sheets which are made to deform under the same forming load uniformly throughout causing unequal and unsatisfactory deformation in the blank. Limiting Dome Height(LDH) test helps predicting the formability of each blanks and assists in determining the appropriate TWB. Finite Element Simulation of LDH test for both base material and TWBs was performed and analysed for both before and after the solution heat treatment. The comparison and validation of simulation results are done with the experimental data and correlated accordingly.

The fractured rocks then present ideal space for oil that can migrate and get trapped. If such moving of hydrocarbons passes uranium-carrying rock units (e.g., shales), uranium is collected and enriched by organic carbon compounds. Brines from the salt body are also ideal carriers for oxidized uranium species and will further dislocate uranium when in contact with uranium-enriched oils. Uranium then has the potential to mineralize in the vicinity of the dome (blue halite is evidence for radiation having affected salt deposits elsewhere in the world). Based on this knowledge, the Qarat Kibrit salt dome was investigated by a well-established geophysical method like very low frequency electromagnetic (VLF-EM) along five traverses approximately 250 m in length (10 m intervals) in order to identify subsurface fault systems. In-phase and quadrature components of the VLF-EM signal were recorded at two different transmitter frequencies (24.0 and 24.9 kHz). The images of Fraser filtered response of the in-phase components indicate a conductive zone (fault) in the southeast and southwest of the study area. The Karous-Hjelt current density pseudo section delineates subsurface faults at depths between 10 and 40 m. The stacked profiles of the Fraser filtered responses brought out two plausible trends/directions of faults. However, there seems to be no evidence for uranium enrichment has been recorded in this area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=salt%20dome" title="salt dome">salt dome</a>, <a href="https://publications.waset.org/abstracts/search?q=uranium" title=" uranium"> uranium</a>, <a href="https://publications.waset.org/abstracts/search?q=fault" title=" fault"> fault</a>, <a href="https://publications.waset.org/abstracts/search?q=in-phase%20component" title=" in-phase component"> in-phase component</a>, <a href="https://publications.waset.org/abstracts/search?q=quadrature%20component" title=" quadrature component"> quadrature component</a>, <a href="https://publications.waset.org/abstracts/search?q=Fraser%20filter" title=" Fraser filter"> Fraser filter</a>, <a href="https://publications.waset.org/abstracts/search?q=Karous-Hjelt%20current%20density" title=" Karous-Hjelt current density"> Karous-Hjelt current density</a> </p> <a href="https://publications.waset.org/abstracts/70092/on-the-qarat-kibrit-salt-dome-faulting-system-south-of-adam-oman-in-search-of-uranium-anomalies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70092.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">240</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">32</span> Climate Physical Processes Mathematical Modeling for Dome-Like Traditional Residential Building</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Artem%20Sedov">Artem Sedov</a>, <a href="https://publications.waset.org/abstracts/search?q=Aigerim%20Uyzbayeva"> Aigerim Uyzbayeva</a>, <a href="https://publications.waset.org/abstracts/search?q=Valeriya%20Tyo"> Valeriya Tyo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The presented article is showing results of dynamic modeling with Mathlab software of optimal automatic room climate control system for two experimental houses in Astana, one of which has circle plan and the other one has square plan.

The frequency of 50Hz has been chosen to improve penetration length through metal. In this design, the liquid metal, strongly stirred by electromagnetic effects, presents shape of a dome caused by strong Laplace forces developing in the bulk of bath. Because of a lower density, the glass phase is located above the metal phase and is heated and stirred by metal through interface. Electric parameters (Intensity, frequency) give precious information about metal load and composition (resistivity of alloy) through impedance modification. Then, power supply can be adapted to energy transfer efficiency for suitable process supervision. Modeling of this system allows prediction of metal dome shape (in agreement with experimental measurement with a specific device), glass and metal velocity, heat and motion transfer through interface. MHD modeling is achieved with COMSOL and Fluent. First, a simplified model is used to obtain the shape of the metal dome. Then the shape is fixed to calculate the fluid flow and the thermal part. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20stirring" title="electromagnetic stirring">electromagnetic stirring</a>, <a href="https://publications.waset.org/abstracts/search?q=induction%20heating" title=" induction heating"> induction heating</a>, <a href="https://publications.waset.org/abstracts/search?q=interface%20modeling" title=" interface modeling"> interface modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20load" title=" metal load"> metal load</a> </p> <a href="https://publications.waset.org/abstracts/83643/induction-heating-and-electromagnetic-stirring-of-bi-phasic-metalglass-molten-bath-for-mixed-nuclear-waste-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83643.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">267</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">30</span> Influence of Geometry on Performance of Type-4 Filament Wound Composite Cylinder for Compressed Gas Storage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pranjali%20%20Sharma">Pranjali Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Swati%20Neogi"> Swati Neogi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Composite pressure vessels are low weight structures mainly used in a variety of applications such as automobiles, aeronautics and chemical engineering. Fiber reinforced polymer (FRP) composite materials offer the simplicity of design and use, high fuel storage capacity, rapid refueling capability, excellent shelf life, minimal infrastructure impact, high safety due to the inherent strength of the pressure vessel, and little to no development risk. Apart from these preliminary merits, the subsidized weight of composite vessels over metallic cylinders act as the biggest asset to the automotive industry, increasing the fuel efficiency. The result is a lightweight, flexible, non-explosive, and non-fragmenting pressure vessel that can be tailor-made to attune with specific applications. The winding pattern of the composite over-wrap is a primary focus while designing a pressure vessel. The critical stresses in the system depend on the thickness, angle and sequence of the composite layers. The composite over-wrap is wound over a plastic liner, whose geometry can be varied for the ease of winding. In the present study, we aim to optimize the FRP vessel geometry that provides an ease in winding and also aids in weight reduction for enhancing the vessel performance. Finite element analysis is used to study the effect of dome geometry, yielding a design with maximum value of burst pressure and least value of vessel weight. The stress and strain analysis of different dome ends along with the cylindrical portion is carried out in ANSYS 19.2. The failure is predicted using different failure theories like Tsai-Wu theory, Tsai-Hill theory and Maximum stress theory. Corresponding to a given winding sequence, the optimum dome geometry is determined for a fixed internal pressure to identify the theoretical value of burst pressure. Finally, this geometry is used to decrease the number of layers to reach the set value of safety in accordance with the available safety standards. This results in decrease in the weight of the composite over-wrap and manufacturing cost of the pressure vessel. An improvement in the overall weight performance of the pressure vessel gives higher fuel efficiency for its use in automobile applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Compressed%20Gas%20Storage" title="Compressed Gas Storage">Compressed Gas Storage</a>, <a href="https://publications.waset.org/abstracts/search?q=Dome%20geometry" title=" Dome geometry"> Dome geometry</a>, <a href="https://publications.waset.org/abstracts/search?q=Theoretical%20Analysis" title=" Theoretical Analysis"> Theoretical Analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Type-4%20Composite%20Pressure%20Vessel" title=" Type-4 Composite Pressure Vessel"> Type-4 Composite Pressure Vessel</a>, <a href="https://publications.waset.org/abstracts/search?q=Improvement%20in%20Vessel%20Weight%20Performance" title=" Improvement in Vessel Weight Performance"> Improvement in Vessel Weight Performance</a> </p> <a href="https://publications.waset.org/abstracts/120757/influence-of-geometry-on-performance-of-type-4-filament-wound-composite-cylinder-for-compressed-gas-storage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120757.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">147</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">29</span> Optimization of Solar Tracking Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Zaher">A.

Considering the weather case, the direct sunlight is more important than the diffuse radiation in case of clear sky. Thus, the panel is always pointed towards the sun. In case of an overcast sky, the solar beam is close to zero, and the panel is placed horizontally to receive the maximum of diffuse radiation. Under partly covered conditions, the panel must be pointed towards the source that emits the maximum of solar energy and it may be anywhere in the sky dome. Thus, the idea of our approach is to analyze the images, captured by ground-based sky camera system, in order to detect the zone in the sky dome which is considered as the optimal source of energy under cloudy conditions. The proposed approach is implemented using experimental setup developed at PROMES-CNRS laboratory in Perpignan city (France). Under overcast conditions, the results were very satisfactory, and the intelligent approach has provided efficiency gains of up to 9% relative to conventional continuous sun tracking systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clouds%20detection" title="clouds detection">clouds detection</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20inference%20systems" title=" fuzzy inference systems"> fuzzy inference systems</a>, <a href="https://publications.waset.org/abstracts/search?q=images%20processing" title=" images processing"> images processing</a>, <a href="https://publications.waset.org/abstracts/search?q=sun%20trackers" title=" sun trackers"> sun trackers</a> </p> <a href="https://publications.waset.org/abstracts/78393/optimization-of-solar-tracking-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78393.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">192</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">28</span> Analysis of Ancient and Present Lightning Protection Systems of Large Heritage Stupas in Sri Lanka</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.R.S.S.%20Kumara">J.R.S.S.

When such structures are large and tall, the risk of lightning initiated from both cloud and ground can be high. This paper presents a lightning risk analysis of three giant stupas in Anuradhapura era (fourth century BC onwards) in Sri Lanka. The three stupas are Jethawaaramaya (269-296 AD), Abayagiriya (88-76 BC) and Ruwanweliseya (161-137 BC), the third, fifth and seventh largest ancient structures in the world. These stupas are solid brick structures consisting of a base, a near hemispherical dome and a conical spire on the top. The ancient stupas constructed with a dielectric crystal on the top and connected to the ground through a conducting material, was considered as the hypothesis for their original lightning protection technique. However, at present, all three stupas are protected with Franklin rod type air termination systems located on top of the spire. First, a risk analysis was carried out according to IEC 62305 by considering the isokeraunic level of the area and the height of the stupas. Then the standard protective angle method and rolling sphere method were used to locate the possible touching points on the surface of the stupas. The study was extended to estimate the critical current which could strike on the unprotected areas of the stupas. The equations proposed by (Uman 2001) and (Cooray2007) were used to find the striking distances. A modified version of rolling sphere method was also applied to see the effects of upward leaders. All these studies were carried out for two scenarios: with original (i.e. ancient) lightning protection system and with present (i.e. new) air termination system. The field distribution on the surface of the stupa in the presence of a downward leader was obtained using finite element based commercial software COMSOL Multiphysics for further investigations of lightning risks. The obtained results were analyzed and compared each other to evaluate the performance of ancient and new lightning protection methods and identify suitable methods to design lightning protection systems for stupas. According to IEC standards, all three stupas with new and ancient lightning protection system has Level IV protection as per protection angle method. However according to rolling sphere method applied with Uman’s equation protection level is III. The same method applied with Cooray’s equation always shows a high risk with respect to Uman’s equation. It was found that there is a risk of lightning strikes on the dome and square chamber of the stupa, and the corresponding critical current values were different with respect to the equations used in the rolling sphere method and modified rolling sphere method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stupa" title="Stupa">Stupa</a>, <a href="https://publications.waset.org/abstracts/search?q=heritage" title=" heritage"> heritage</a>, <a href="https://publications.waset.org/abstracts/search?q=lightning%20protection" title=" lightning protection"> lightning protection</a>, <a href="https://publications.waset.org/abstracts/search?q=rolling%20sphere%20method" title=" rolling sphere method"> rolling sphere method</a>, <a href="https://publications.waset.org/abstracts/search?q=protection%20level" title=" protection level"> protection level</a> </p> <a href="https://publications.waset.org/abstracts/93136/analysis-of-ancient-and-present-lightning-protection-systems-of-large-heritage-stupas-in-sri-lanka" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93136.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">252</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">27</span> Experimental and Finite Element Forming Limit Diagrams for Interstitial Free Steels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Basavaraj%20Vadavadagi">Basavaraj Vadavadagi</a>, <a href="https://publications.waset.org/abstracts/search?q=Satishkumar%20Shekhawat"> Satishkumar Shekhawat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Interstitial free steels posses better formability and have many applications in automotive industries.

In this study, the experimental and FE simulated FLDs are compared and also the stress based FLDs were investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forming%20limit%20diagram" title="forming limit diagram">forming limit diagram</a>, <a href="https://publications.waset.org/abstracts/search?q=limiting%20dome%20height" title=" limiting dome height"> limiting dome height</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20strain%20measurement" title=" optical strain measurement"> optical strain measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=interstitial" title=" interstitial"> interstitial</a> </p> <a href="https://publications.waset.org/abstracts/3534/experimental-and-finite-element-forming-limit-diagrams-for-interstitial-free-steels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3534.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">232</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">26</span> A Practical Construction Technique to Enhance the Performance of Rock Bolts in Tunnels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ojas%20Chaudhari">Ojas Chaudhari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Nejad%20Ghafar"> Ali Nejad Ghafar</a>, <a href="https://publications.waset.org/abstracts/search?q=Giedrius%20Zirgulis"> Giedrius Zirgulis</a>, <a href="https://publications.waset.org/abstracts/search?q=Marjan%20Mousavi"> Marjan Mousavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Tommy%20Ellison"> Tommy Ellison</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Pousette"> Sandra Pousette</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Fontana"> Patrick Fontana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Swedish tunnel construction, a critical issue that has been repeatedly acknowledged is corrosion and, consequently, failure of the rock bolts in rock support systems. The defective installation of rock bolts results in the formation of cavities in the cement mortar that is regularly used to fill the area under the dome plates. These voids allow for water-ingress to the rock bolt assembly, which results in corrosion of rock bolt components and eventually failure. In addition, the current installation technique consists of several manual steps with intense labor works that are usually done in uncomfortable and exhausting conditions, e.g., under the roof of the tunnels. Such intense tasks also lead to a considerable waste of materials and execution errors. Moreover, adequate quality control of the execution is hardly possible with the current technique. To overcome these issues, a non-shrinking/expansive cement-based mortar filled in the paper packaging has been developed in this study which properly fills the area under the dome plates without or with the least remaining cavities, ultimately that diminishes the potential of corrosion. This article summarizes the development process and the experimental evaluation of this technique for the installation of rock bolts. In the development process, the cementitious mortar was first developed using specific cement and shrinkage reducing/expansive additives. The mechanical and flow properties of the mortar were then evaluated using compressive strength, density, and slump flow measurement methods. In addition, isothermal calorimetry and shrinkage/expansion measurements were used to elucidate the hydration and durability attributes of the mortar. After obtaining the desired properties in both fresh and hardened conditions, the developed dry mortar was filled in specific permeable paper packaging and then submerged in water bath for specific intervals before the installation. The tests were enhanced progressively by optimizing different parameters such as shape and size of the packaging, characteristics of the paper used, immersion time in water and even some minor characteristics of the mortar. Finally, the developed prototype was tested in a lab-scale rock bolt assembly with various angles to analyze the efficiency of the method in real life scenario. The results showed that the new technique improves the performance of the rock bolts by reducing the material wastage, improving environmental performance, facilitating and accelerating the labor works, and finally enhancing the durability of the whole system. Accordingly, this approach provides an efficient alternative for the traditional way of tunnel bolt installation with considerable advantages for the Swedish tunneling industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrosion" title="corrosion">corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=durability" title=" durability"> durability</a>, <a href="https://publications.waset.org/abstracts/search?q=mortar" title=" mortar"> mortar</a>, <a href="https://publications.waset.org/abstracts/search?q=rock%20bolt" title=" rock bolt"> rock bolt</a> </p> <a href="https://publications.waset.org/abstracts/129432/a-practical-construction-technique-to-enhance-the-performance-of-rock-bolts-in-tunnels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129432.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">112</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">25</span> Structural Optimization Using Catenary and Other Natural Shapes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mitchell%20Gohnert">Mitchell Gohnert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper reviews some fundamental concepts of structural optimization, which is focused on the shape of the structure. Bending stresses produce high peak stresses at each face of the member, and therefore, substantially more material is required to resist bending. The shape of the structure has a profound effect on stress levels. Stress may be reduced dramatically by simply changing the shape to accommodate natural stress flow. The main objective of structural optimization is to direct the thrust line along the axis of the member. Optimal shapes include the catenary arch or dome, triangular shapes, and columns. If the natural flow of stress matches the shape of the structures, the most optimal shape is determined. Structures, however, must resist multiple load patterns. An optimal shape is still possible by ensuring that the thrust lines fall within the middle third of the member. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optimization" title="optimization">optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20structures" title=" natural structures"> natural structures</a>, <a href="https://publications.waset.org/abstracts/search?q=shells" title=" shells"> shells</a>, <a href="https://publications.waset.org/abstracts/search?q=catenary" title=" catenary"> catenary</a>, <a href="https://publications.waset.org/abstracts/search?q=domes" title=" domes"> domes</a>, <a href="https://publications.waset.org/abstracts/search?q=arches" title=" arches"> arches</a> </p> <a href="https://publications.waset.org/abstracts/186769/structural-optimization-using-catenary-and-other-natural-shapes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186769.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">43</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">24</span> Strip Size Optimization for Spiral Type Actuator Coil Used in Electromagnetic Flat Sheet Forming Experiment </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20A.%20Aleem">M.

Copper strip was chosen as the material for designing the actuator coil. Relationship between height to width ratio (S-factor) of the copper strip and coil’s performance has been studied. Magnetic field intensities, eddy currents, and Lorentz force were calculated for the coils that were designed using six different 'S-factor' values (0.65, 0.75, 1.05, 1.25, 1.54 and 1.75), keeping the cross-sectional area of strip the same. Results obtained through simulation suggest that actuator coil with S-factor ~ 1 shows optimum forming performance as it exerts maximum Lorentz force (84 kN) on work piece. The same coils were fabricated and used for electromagnetic sheet forming experiments. Aluminum 6061 sheets of thickness 1.5 mm have been formed using different voltage levels of capacitor bank. Smooth forming profiles were obtained with dome heights 28, 35 and 40 mm in work piece at 800, 1150 and 1250 V respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FEM%20modelling" title="FEM modelling">FEM modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20forming" title=" electromagnetic forming"> electromagnetic forming</a>, <a href="https://publications.waset.org/abstracts/search?q=spiral%20coil" title=" spiral coil"> spiral coil</a>, <a href="https://publications.waset.org/abstracts/search?q=Lorentz%20force" title=" Lorentz force"> Lorentz force</a> </p> <a href="https://publications.waset.org/abstracts/86282/strip-size-optimization-for-spiral-type-actuator-coil-used-in-electromagnetic-flat-sheet-forming-experiment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86282.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">286</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">23</span> The Kadiria Zawiya: Architecture and Islamic Sufi Paradigm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghada%20Chater">Ghada Chater</a>, <a href="https://publications.waset.org/abstracts/search?q=Mounir%20Dhouib"> Mounir Dhouib</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Zawiyas are mausoleums where saints called 'waly' are buried and where ritual practices of Sufi Islamic movement take place. These funerary monuments have constituted since the medieval period a fundamental component of rural and urban Islamic landscape, especially that of Tunisia.The hypothesis is that these monuments reflect in their architecture the Sufi underlying thought. The paper’s target is to verify the validity of this hypothesis and possibly show the incarnation mode of Islamic Sufi paradigm in the zawiya’s architecture. This study considers the main Zawiya of one of the most important religious brotherhoods in Tunisia, which is Kadiria. A morphological analysis has been conducted and crossed later to a spiritual hermeneutic test. The result of this confrontation was significant: the paradigmatic element of the zawiya, materialized by the esoteric / exoteric dome 'kubba', returns in its geometry and structure to one of the Sufism key concepts: the unity of the creative spirit in the diversity and plurality of evanescent bodies. Thus, the creative act finds its reflection not only in the spirit of the perfect human microcosm (the waly microcosm), but also within the building dedicated to him. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=architecture" title="architecture">architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=Islam" title=" Islam"> Islam</a>, <a href="https://publications.waset.org/abstracts/search?q=Sufism" title=" Sufism"> Sufism</a>, <a href="https://publications.waset.org/abstracts/search?q=waly" title=" waly"> waly</a>, <a href="https://publications.waset.org/abstracts/search?q=zawiya" title=" zawiya"> zawiya</a> </p> <a href="https://publications.waset.org/abstracts/58775/the-kadiria-zawiya-architecture-and-islamic-sufi-paradigm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58775.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">22</span> Performance Analysis on the Smoke Management System of the Weiwuying Center for the Arts Using Hot Smoke Tests</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20H.%20Yang">K.

The city alone is home to seven UNESCO’s world heritage sites including various public squares and religious sanctums which are often regarded as living heritages by various historians and archeological explorers. Recently on April 25, 2015, the capital city including other nearby locations was struck with Gorkha earthquake of moment magnitude (Mw) 7.8, followed by the strongest aftershock of moment magnitude (Mw) 7.3 on May 12. This study reports structural failures and collapse of heritage structures in Kathmandu Valley during the earthquake and presents preliminary findings as to the causes of failures and collapses. Field reconnaissance was carried immediately after the main shock and the aftershock, in major heritage sites: UNESCO world heritage sites, a number of temples and historic buildings in Kathmandu Durbar Square, Patan Durbar Square, and Bhaktapur Durbar Square. Despite such catastrophe, a significant number of heritage structures stood high, performing very well during the earthquake. Preliminary reports from archeological department suggest that 721 of such structures were severely affected, whereas numbers within the valley only were 444 including 76 structures which were completely collapsed. This study presents recorded accelerograms and geology of Kathmandu Valley. Structural typology and architecture of the heritage structures in Kathmandu Valley are briefly described. Case histories of damaged heritage structures, the patterns, and the failure mechanisms are also discussed in this paper. It was observed that performance of heritage structures was influenced by the multiple factors such as structural and architecture typology, configuration, and structural deficiency, local ground site effects and ground motion characteristics, age and maintenance level, material quality etc. Most of such heritage structures are of masonry type using bricks and earth-mortar as a bonding agent. The walls' resistance is mainly compressive, thus capable of withstanding vertical static gravitational load but not horizontal dynamic seismic load. There was no definitive pattern of damage to heritage structures as most of them behaved as a composite structure. Some structures were extensively damaged in some locations, while structures with similar configuration at nearby location had little or no damage. Out of major heritage structures, Dome, Pagoda (2, 3 or 5 tiered temples) and Shikhara structures were studied with similar variables. Studying varying degrees of damages in such structures, it was found that Shikhara structures were most vulnerable one where Dome structures were found to be the most stable one, followed by Pagoda structures. The seismic performance of the masonry-timber and stone masonry structures were slightly better than that of the masonry structures. Regular maintenance and periodic seismic retrofitting seems to have played pivotal role in strengthening seismic performance of the structure. The study also recommends some key functions to strengthen the seismic performance of such structures through study based on structural analysis, building material behavior and retrofitting details. The result also recognises the importance of documentation of traditional knowledge and its revised transformation in modern technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gorkha%20earthquake" title="Gorkha earthquake">Gorkha earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=field%20observation" title=" field observation"> field observation</a>, <a href="https://publications.waset.org/abstracts/search?q=heritage%20structure" title=" heritage structure"> heritage structure</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20performance" title=" seismic performance"> seismic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=masonry%20building" title=" masonry building"> masonry building</a> </p> <a href="https://publications.waset.org/abstracts/93105/observation-on-the-performance-of-heritage-structures-in-kathmandu-valley-nepal-during-the-2015-gorkha-earthquake" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93105.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">151</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">20</span> The Evaluation of Islamic Concept in Contemporary Mosque Design with the Case of Study: Jogokariyan Mosque Yogyakarta Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Malik">Ibrahim Malik</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Ikramullah%20al%20Kambuna"> M.

The results of this study should be found on the evaluation of the integrated design of contemporary mosques are based on a study of the Quran and Hadith. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=characteristics" title="characteristics">characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=Islamic%20concept" title=" Islamic concept"> Islamic concept</a>, <a href="https://publications.waset.org/abstracts/search?q=culture" title=" culture"> culture</a>, <a href="https://publications.waset.org/abstracts/search?q=Kauman%20Mosque" title=" Kauman Mosque"> Kauman Mosque</a> </p> <a href="https://publications.waset.org/abstracts/59771/the-characteristics-of-islamic-concept-in-contemporary-mosque-design-with-the-case-modulation-of-study-kauman-mosque-yogyakarta-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59771.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">225</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">17</span> Endometriosis, Bladder Endometriosis (BE), Urinary Tract Endometriosis (UTE), Robotic-Assisted Surgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farida%20Eid">Farida Eid</a>, <a href="https://publications.waset.org/abstracts/search?q=Hala%20Nasseif"> Hala Nasseif</a>, <a href="https://publications.waset.org/abstracts/search?q=Hana%20Mokhtar"> Hana Mokhtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Labib%20Riachi"> Labib Riachi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mudhar%20Hasan"> Mudhar Hasan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bladder Endometriosis is a rare form of endometriosis and is defined as the presence of endometriotic tissue in the detrusor muscle of the bladder, either in full or partial thickness. Women typically present with dysuria, urinary frequency, hematuria, and recurrent urinary tract infections. Bladder endometriosis is typically found at the bladder base and bladder dome. Transvaginal ultrasound is considered first-line imaging, and the condition is typically managed with laparoscopic partial cystectomy. A 33-year-old nulliparous woman presented with chronic pelvic pain, severe dysmenorrhea, and metrorrhagia. The patient was previously diagnosed with bladder endometriomas two years ago with multiple recurrences. MRI revealed urinary bladder endometriosis measuring 3 x 2 x 1.5 cm. Accordingly, the patient underwent a cystoscopy-guided robotic-assisted excision of the endometriotic implant in the bladder with cystotomy and repair of the bladder mucosa. The operation was tolerated well, and the postoperative period was uneventful. Bladder Endometriosis (BE) typically presents with urinary symptoms and can be mistaken for a bladder tumor upon further imaging. The case was successfully managed with cystoscopy-guided, robotic-assisted excision and fulguration of the endometriotic implant in the bladder. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=endometriosis" title="endometriosis">endometriosis</a>, <a href="https://publications.waset.org/abstracts/search?q=bladder%20endometriosis%20%28BE%29" title=" bladder endometriosis (BE)"> bladder endometriosis (BE)</a>, <a href="https://publications.waset.org/abstracts/search?q=urinary%20tract%20endometriosis%20%28UTE%29" title=" urinary tract endometriosis (UTE)"> urinary tract endometriosis (UTE)</a>, <a href="https://publications.waset.org/abstracts/search?q=robotic-assisted%20surgery" title=" robotic-assisted surgery"> robotic-assisted surgery</a> </p> <a href="https://publications.waset.org/abstracts/189818/endometriosis-bladder-endometriosis-be-urinary-tract-endometriosis-ute-robotic-assisted-surgery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189818.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">30</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">16</span> Probability-Based Damage Detection of Structures Using Kriging Surrogates and Enhanced Ideal Gas Molecular Movement Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20R.%20Ghasemi">M.

However, uncertainties existing in the measured vibration data may lead to false or unreliable output result from such model. In this study, an efficient approach based on Monte Carlo simulation is proposed to take into account the effect of uncertainties in developing a surrogate model. The probability of damage existence (PDE) is calculated based on the probability density function of the existence of undamaged and damaged states. The kriging technique allows one to genuinely quantify the surrogate error, therefore it is chosen as metamodeling technique. Enhanced version of ideal gas molecular movement (EIGMM) algorithm is used as main algorithm for model updating. The developed approach is applied to detect simulated damage in numerical models of 72-bar space truss and 120-bar dome truss. The simulation results show the proposed method can perform well in probability-based damage detection of structures with less computational effort compared to direct finite element model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=probability-based%20damage%20detection%20%28PBDD%29" title="probability-based damage detection (PBDD)">probability-based damage detection (PBDD)</a>, <a href="https://publications.waset.org/abstracts/search?q=Kriging" title=" Kriging"> Kriging</a>, <a href="https://publications.waset.org/abstracts/search?q=surrogate%20modeling" title=" surrogate modeling"> surrogate modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertainty%20quantification" title=" uncertainty quantification"> uncertainty quantification</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=enhanced%20ideal%20gas%20molecular%20movement%20%28EIGMM%29" title=" enhanced ideal gas molecular movement (EIGMM)"> enhanced ideal gas molecular movement (EIGMM)</a> </p> <a href="https://publications.waset.org/abstracts/56392/probability-based-damage-detection-of-structures-using-kriging-surrogates-and-enhanced-ideal-gas-molecular-movement-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56392.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">239</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">15</span> Evaluation of Deformable Boundary Condition Using Finite Element Method and Impact Test for Steel Tubes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abed%20Ahmed">Abed Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehrdad%20Asadi"> Mehrdad Asadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jennifer%20Martay"> Jennifer Martay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Stainless steel pipelines are crucial components to transportation and storage in the oil and gas industry. However, the rise of random attacks and vandalism on these pipes for their valuable transport has led to more security and protection for incoming surface impacts. These surface impacts can lead to large global deformations of the pipe and place the pipe under strain, causing the eventual failure of the pipeline. Therefore, understanding how these surface impact loads affect the pipes is vital to improving the pipes’ security and protection. In this study, experimental test and finite element analysis (FEA) have been carried out on EN3B stainless steel specimens to study the impact behaviour. Low velocity impact tests at 9 m/s with 16 kg dome impactor was used to simulate for high momentum impact for localised failure. FEA models of clamped and deformable boundaries were modelled to study the effect of the boundaries on the pipes impact behaviour on its impact resistance, using experimental and FEA approach. Comparison of experimental and FE simulation shows good correlation to the deformable boundaries in order to validate the robustness of the FE model to be implemented in pipe models with complex anisotropic structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20impact" title="dynamic impact">dynamic impact</a>, <a
