In this study, to improve the seismic performance of SCBFs connections, an analytical study was undertaken. To improve the gusset plate connection, this study proposes using ‎edge’s stiffeners in both sides of gusset plate.‎ For this purpose, in order to examine edge’s stiffeners effect on gusset plate connections, two groups of modeling with and without considering edge’s stiffener and different types of braces were modeled using ABAQUS software. The results show that considering the edge’s stiffener reduces the equivalent plastic strain values at a connection region of gusset plate with beam and column, which can improve the seismic performance of gusset plate. Furthermore, considering the edge’s stiffeners significantly decreases the strain concentration at regions where gusset plates have been connected to beam and column. Moreover, considering 2t<sub>pl</sub> distance causes reduction in the plastic strain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=special%20concentrically%20braced%20frame" title="special concentrically braced frame">special concentrically braced frame</a>, <a href="https://publications.waset.org/abstracts/search?q=gusset%20plate" title=" gusset plate"> gusset plate</a>, <a href="https://publications.waset.org/abstracts/search?q=edge%27s%20stiffener" title=" edge's stiffener"> edge's stiffener</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20performance" title=" seismic performance"> seismic performance</a> </p> <a href="https://publications.waset.org/abstracts/115527/effects-of-using-gusset-plate-stiffeners-on-the-seismic-performance-of-concentrically-braced-frame" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115527.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">128</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">847</span> Effect of Stiffeners on the Behavior of Slender Built up Steel I-Beams</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20E.%20Abou-Hashem%20El%20Dib">M.

Aghilesh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fluid-structure interaction is a crucial consideration in the design of many engineering systems such as flight vehicles and bridges. Aircraft lifting surfaces and turbine blades can fail due to oscillations caused by fluid-structure interaction. Hence, it is focussed to study the fluid-structure interaction in the present research. First, the effect of free vibration over the panel is studied. It is well known that the deformation of a panel and flow induced forces affects one another. The selected panel has a span 300mm, chord 300mm and thickness 2 mm. The project is to study, the effect of cross-sectional area and the stiffener location is carried out for the same panel. The stiffener spacing is varied along both the chordwise and span-wise direction. Then for that optimal location the ideal stiffener length is identified. The effect of stiffener cross-section shapes (T, I, Hat, Z) over flutter velocity has been conducted. The flutter velocities of the selected panel with two rectangular stiffeners of cantilever configuration are estimated using MSC NASTRAN software package. As the flow passes over the panel, deformation takes place which further changes the flow structure over it. With increasing velocity, the deformation goes on increasing, but the stiffness of the system tries to dampen the excitation and maintain equilibrium. But beyond a critical velocity, the system damping suddenly becomes ineffective, so it loses its equilibrium. This estimated in NASTRAN using PK method. The first 10 modal frequencies of a simple panel and stiffened panel are estimated numerically and are validated with open literature. A grid independence study is also carried out and the modal frequency values remain the same for element lengths less than 20 mm. The current investigation concludes that the span-wise stiffener placement is more effective than the chord-wise placement. The maximum flutter velocity achieved for chord-wise placement is 204 m/s while for a span-wise arrangement it is augmented to 963 m/s for the stiffeners location of ¼ and ¾ of the chord from the panel edge (50% of chord from either side of the mid-chord line). The flutter velocity is directly proportional to the stiffener cross-sectional area. A significant increment in flutter velocity from 218m/s to 1024m/s is observed for the stiffener lengths varying from 50% to 60% of the span. The maximum flutter velocity above Mach 3 is achieved. It is also observed that for a stiffened panel, the full effect of stiffener can be achieved only when the stiffener end is clamped. Stiffeners with Z cross section incremented the flutter velocity from 142m/s (Panel with no stiffener) to 328 m/s, which is 2.3 times that of simple panel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stiffener%20placement" title="stiffener placement">stiffener placement</a>, <a href="https://publications.waset.org/abstracts/search?q=stiffener%20cross-sectional%20area" title=" stiffener cross-sectional area"> stiffener cross-sectional area</a>, <a href="https://publications.waset.org/abstracts/search?q=stiffener%20length" title=" stiffener length"> stiffener length</a>, <a href="https://publications.waset.org/abstracts/search?q=stiffener%20cross%20sectional%20area%20shape" title=" stiffener cross sectional area shape"> stiffener cross sectional area shape</a> </p> <a href="https://publications.waset.org/abstracts/52356/increment-of-panel-flutter-margin-using-adaptive-stiffeners" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52356.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">292</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">845</span> Performance of Stiffened Slender Built up Steel I-Columns</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20E.%20Abou-Hashem%20El%20Dib">M.

As a first step, in the case of a stiffener having an inclined part on the flange, experimental and nonlinear finite element analysis are carried out for three different upright lengths. In the uprights with long length, global buckling is observed while distortional buckling and local buckling are observed in the uprights with medium length and those with short length, respectively. After this point, the study is divided into two groups. One of these groups is the case where the stiffener on the flange is folded at 90°. For this case, four different distances of the stiffener from the web are taken into account. In the other group, the case where different depth of stiffener on the web is considered. Combining experimental and finite element results, the cross-section giving the ultimate critical buckling load is selected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=steel" title="steel">steel</a>, <a href="https://publications.waset.org/abstracts/search?q=upright" title=" upright"> upright</a>, <a href="https://publications.waset.org/abstracts/search?q=buckling" title=" buckling"> buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=modes" title=" modes"> modes</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20finite%20element%20analysis" title=" nonlinear finite element analysis"> nonlinear finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/64991/improvement-of-buckling-behavior-of-cold-formed-steel-uprights-with-open-cross-section-used-in-storage-rack-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64991.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">260</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">843</span> The Need for Multi-Edge Strategies and Solutions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hugh%20Taylor">Hugh Taylor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Industry analysts project that edge computing will be generating tens of billions in revenue in coming years. It’s not clear, however, if this will actually happen, and who, if anyone, will make it happen. Edge computing is seen as a critical success factor in industries ranging from telecom, enterprise IT and co-location. However, will any of these industries actually step up to make edge computing into a viable technology business? This paper looks at why the edge seems to be in a chasm, on the edge of realization, so to speak, but failing to coalesce into a coherent technology category like the cloud—and how the segment’s divergent industry players can come together to build a viable business at the edge. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=edge%20computing" title="edge computing">edge computing</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-edge%20strategies" title=" multi-edge strategies"> multi-edge strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=edge%20data%20centers" title=" edge data centers"> edge data centers</a>, <a href="https://publications.waset.org/abstracts/search?q=edge%20cloud" title=" edge cloud"> edge cloud</a> </p> <a href="https://publications.waset.org/abstracts/154144/the-need-for-multi-edge-strategies-and-solutions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154144.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">105</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">842</span> Experimental Model of the Behaviour of Bolted Angles Connections with Stiffeners</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdulkadir%20Cuneyt%20Aydin">Abdulkadir Cuneyt Aydin</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahyar%20Maali"> Mahyar Maali</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmut%20K%C4%B1l%C4%B1%C3%A7"> Mahmut Kılıç</a>, <a href="https://publications.waset.org/abstracts/search?q=Merve%20Sa%C4%9F%C4%B1ro%C4%9Flu"> Merve Sağıroğlu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The moment-rotation curves of semi-rigid connections are the visual expressions of the actual behaviour discovered in beam-to-column connections experiments. This research was to determine the behaviour of the connection using full-scale experiments under statically loaded. The stiffeners which are typically attached to beams web or flanges to control local buckling and to increase shear capacity in a beam web are almost always used in modern designs. They must also provide sufficient moment of inertia to control out of plane deformations. This study was undertaken to analyse the influence of stiffeners in the angles and beams on the behaviour of the beam-to-column joints. In addition, the aim was to provide necessary data to improve the Eurocode 3. The main parameters observed are the evolution of the resistance, the stiffness, the rotation capacity, the ductility of a joint and the Energy Dissipation. Experimental tests show that the plastic flexural resistance and the energy dissipation increased when thickness of stiffener beam, thickness of stiffener angles were increased in the test specimens. And also, while stiffness of joints, the bending moment capacity and the maximum bending moment increased with the increasing thickness of stiffener beam, these values decreased with the increasing thickness of stiffener angles. So, it is observed that the beam stiffener of angles are important in improving resistance moment of beam-to-column semi-rigid joints. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bolted%20angles%20connection" title="bolted angles connection">bolted angles connection</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-rigid%20joints" title=" semi-rigid joints"> semi-rigid joints</a>, <a href="https://publications.waset.org/abstracts/search?q=ductility%20of%20a%20joint" title=" ductility of a joint"> ductility of a joint</a>, <a href="https://publications.waset.org/abstracts/search?q=angles%20and%20beams%20stiffeners" title=" angles and beams stiffeners"> angles and beams stiffeners</a> </p> <a href="https://publications.waset.org/abstracts/54503/experimental-model-of-the-behaviour-of-bolted-angles-connections-with-stiffeners" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54503.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">460</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">841</span> An investigation of Leading Edge and Trailing Edge Corrugation for Low Reynolds Number Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syed%20Hassan%20Raza%20Shah">Syed Hassan Raza Shah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Mohammad%20Ali"> Mohammad Mohammad Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The flow over a smoothly profiled airfoil at a low Reynolds number is highly susceptible to separate even at a very low angle of attack. An investigation was made to study the effect of leading-edge and trailing-edge corrugation with the spanwise change in the ridges resulted due to the change in the chord length for an infinite wing. The wind tunnel results using NACA0018 wings revealed that leading and trailing edge corrugation did not have any benefit in terms of aerodynamic efficiency or delayed stall. The leading edge and trailing edge corrugation didn't change the lift curve slope, with the leading edge corrugation wing stalling first in the range of Reynolds number of 50,000 to 125,000. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=leading%20and%20trailing%20edge%20corrugations" title="leading and trailing edge corrugations">leading and trailing edge corrugations</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20reynolds%20number" title=" low reynolds number"> low reynolds number</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20tunnel%20testing" title=" wind tunnel testing"> wind tunnel testing</a>, <a href="https://publications.waset.org/abstracts/search?q=NACA0018" title=" NACA0018"> NACA0018</a> </p> <a href="https://publications.waset.org/abstracts/141121/an-investigation-of-leading-edge-and-trailing-edge-corrugation-for-low-reynolds-number-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141121.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">291</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">840</span> Measurement of VIP Edge Conduction Using Vacuum Guarded Hot Plate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bongsu%20Choi">Bongsu Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae-Ho%20Song"> Tae-Ho Song</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Vacuum insulation panel (VIP) is a promising thermal insulator for buildings, refrigerator, LNG carrier and so on. In general, it has the thermal conductivity of 2~4 mW/m•K. However, this thermal conductivity is that measured at the center of VIP. The total effective thermal conductivity of VIP is larger than this value due to the edge conduction through the envelope. In this paper, the edge conduction of VIP is examined theoretically, numerically and experimentally. To confirm the existence of the edge conduction, numerical analysis is performed for simple two-dimensional VIP model and a theoretical model is proposed to calculate the edge conductivity. Also, the edge conductivity is measured using the vacuum guarded hot plate and the experiment is validated against numerical analysis. The results show that the edge conductivity is dependent on the width of panel and thickness of Al-foil. To reduce the edge conduction, it is recommended that the VIP should be made as big as possible or made of thin Al film envelope. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=envelope" title="envelope">envelope</a>, <a href="https://publications.waset.org/abstracts/search?q=edge%20conduction" title=" edge conduction"> edge conduction</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20conductivity" title=" thermal conductivity"> thermal conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=vacuum%20insulation%20panel" title=" vacuum insulation panel"> vacuum insulation panel</a> </p> <a href="https://publications.waset.org/abstracts/19366/measurement-of-vip-edge-conduction-using-vacuum-guarded-hot-plate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19366.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">405</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">839</span> Effect of Machining Induced Microstructure Changes on the Edge Formability of Titanium Alloys at Room Temperature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=James%20S.%20Kwame">James S.

One major issue of concern for the sheet forming of titanium alloys is their high sensitivity to surface inhomogeneity. Various machining processes are utilised in preparing sheet hole edges for edge flanging applications. However, the response of edge forming tendencies of titanium to different edge surface finishes is not well investigated. The hole expansion test is used in this project to elucidate the impact of abrasive water jet (AWJ) and electro-discharge machining (EDM) cutting techniques on the edge formability of CP-Ti (Grade 2) and Ti-3Al-2.5V alloys at room temperature. The results show that the quality of the edge surface finish has a major effect on the edge formability of the materials. The work also found that the variations in the edge forming performance are mainly the result of the influence of machining induced edge surface defects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=titanium%20alloys" title="titanium alloys">titanium alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=hole%20expansion%20test" title=" hole expansion test"> hole expansion test</a>, <a href="https://publications.waset.org/abstracts/search?q=edge%20formability" title=" edge formability"> edge formability</a>, <a href="https://publications.waset.org/abstracts/search?q=non-conventional%20machining" title=" non-conventional machining"> non-conventional machining</a> </p> <a href="https://publications.waset.org/abstracts/110917/effect-of-machining-induced-microstructure-changes-on-the-edge-formability-of-titanium-alloys-at-room-temperature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110917.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">137</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">838</span> An Algorithm to Find Fractional Edge Domination Number and Upper Fractional Edge Domination Number of an Intuitionistic Fuzzy Graph</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karunambigai%20Mevani%20Govindasamy">Karunambigai Mevani Govindasamy</a>, <a href="https://publications.waset.org/abstracts/search?q=Sathishkumar%20Ayyappan"> Sathishkumar Ayyappan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we formulate the algorithm to find out the dominating function parameters of Intuitionistic Fuzzy Graphs(IFG).

In this paper, a simulation program (FCG-System) is developed utilizing the commercial software ABAQUS with its object-oriented programming interface to simulate the fatigue crack path and to compute the corresponding fatigue life. In order to apply FCG-System in large-scale marine structures, the substructure modeling technique is integrated in the system under the consideration of structural details and load shedding during crack growth. Based on the nodal forces and nodal displacements obtained from finite element analysis, a formula for shell elements to compute stress intensity factors is proposed in the view of virtual crack closure technique. The cracks initiating from the intersection of flange and the end of the web-stiffener are investigated for fatigue crack paths and growth lives under water pressure loading and axial force loading, separately. It is found that the FCG-System developed by authors could be an efficient tool to perform fatigue crack growth analysis on marine structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crack%20path" title="crack path">crack path</a>, <a href="https://publications.waset.org/abstracts/search?q=fatigue%20crack" title=" fatigue crack"> fatigue crack</a>, <a href="https://publications.waset.org/abstracts/search?q=fatigue%20live" title=" fatigue live"> fatigue live</a>, <a href="https://publications.waset.org/abstracts/search?q=FCG-system" title=" FCG-system"> FCG-system</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20crack%20closure%20technique" title=" virtual crack closure technique"> virtual crack closure technique</a> </p> <a href="https://publications.waset.org/abstracts/8860/numerical-study-of-fatigue-crack-growth-at-a-web-stiffener-of-ship-structural-details" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8860.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">568</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">828</span> Designing Directed Network with Optimal Controllability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liang%20Bai">Liang Bai</a>, <a href="https://publications.waset.org/abstracts/search?q=Yandong%20Xiao"> Yandong Xiao</a>, <a href="https://publications.waset.org/abstracts/search?q=Haorang%20Wang"> Haorang Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Songyang%20Lao"> Songyang Lao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The directedness of links is crucial to determine the controllability in complex networks. Even the edge directions can determine the controllability of complex networks. Obviously, for a given network, we wish to design its edge directions that make this network approach the optimal controllability. In this work, we firstly introduce two methods to enhance network by assigning edge directions. However, these two methods could not completely mitigate the negative effects of inaccessibility and dilations. Thus, to approach the optimal network controllability, the edge directions must mitigate the negative effects of inaccessibility and dilations as much as possible.

The web is modeled as a viscoelastic plate whose constitutive relation obeys the Kelvin-Voigt model, and the in-plane edge excitations are expressed as the sum of a static tension and a periodical perturbation. Due to the in-plane edge excitations, the moving plate may bring about parametric instability under certain situations. First, the in-plane stresses of the plate due to the nonuniform edge excitations are determined by solving the in-plane forced vibration problem. Then, the dependence on the spatial coordinates in the equation of transverse motion is eliminated by the generalized Galerkin method, which results in a set of discretized system equations in time. Finally, the method of multiple scales is utilized to solve the set of system equations analytically if the periodical perturbation of the in-plane edge excitations is much smaller as compared with the static tension of the plate, from which the stability boundaries of the moving plate are obtained. Numerical results reveal that only combination resonances of the summed-type appear under the in-plane edge excitations considered in this work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=axially%20moving%20viscoelastic%20plate" title="axially moving viscoelastic plate">axially moving viscoelastic plate</a>, <a href="https://publications.waset.org/abstracts/search?q=in-plane%20periodic%20excitation" title=" in-plane periodic excitation"> in-plane periodic excitation</a>, <a href="https://publications.waset.org/abstracts/search?q=nonuniformly%20distributed%20edge%20tension" title=" nonuniformly distributed edge tension"> nonuniformly distributed edge tension</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20stability" title=" dynamic stability"> dynamic stability</a> </p> <a href="https://publications.waset.org/abstracts/26548/dynamic-stability-of-axially-moving-viscoelastic-plates-under-nonuniform-in-plane-edge-excitations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26548.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">322</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">826</span> Manufacturing of Vacuum Glazing with Metal Edge Seal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Won%20Kyeong%20Kang">Won Kyeong Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae-Ho%20Song"> Tae-Ho Song</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Vacuum glazing (VG) is a super insulator, which is able to greatly improve the energy efficiency of building.

This noise can be related to the surface pressure fluctuations, which can be predicted by either CFD or empirical models. However, in reality, the aerofoil or hydrofoil often operates at an angle of attack. Under this situation, the flow is subjected to an Adverse-Pressure-Gradient (APG), and as a result, a flow separation may occur. This study is to assess trailing-edge noise models for such flows. In the present work, the trailing-edge noise from a 2D airfoil at 6 degree of angle of attach is investigated. Under this condition, the flow is experiencing a strong APG, and the flow separation occurs. The flow over the airfoil with a chord of 300 mm, equivalent to a Reynold Number 4x10⁵, is simulated using RANS with the SST k-ɛ turbulent model. The predicted surface pressure fluctuations are compared with the published experimental data and empirical models, and show a good agreement with the experimental data. The effect of the APG on the trailing edge noise is discussed, and the associated trailing edge noise is calculated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aero-acoustics" title="aero-acoustics">aero-acoustics</a>, <a href="https://publications.waset.org/abstracts/search?q=adverse-pressure%20gradient" title=" adverse-pressure gradient"> adverse-pressure gradient</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title=" computational fluid dynamics"> computational fluid dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=trailing-edge%20noise" title=" trailing-edge noise"> trailing-edge noise</a> </p> <a href="https://publications.waset.org/abstracts/65472/prediction-of-trailing-edge-noise-under-adverse-pressure-gradient-effect" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65472.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">336</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">821</span> Embedment Design Concept of Signature Tower in Chennai</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Gobinath">M.

Following assumptions are made for the mathematical modelling of RCC with steel embedment: (1) The bond between the structural steel and concrete is neglected. (2) The stiffener is provided with shear studs to transfer the shear force. Hence nodal connectivity is established between solid nodes (concrete) and shell elements (stiffener) at those locations. (3) As the end reinforcements transfer either tension/compression, it is modeled as line element and connected to solid nodes. (4) In order to capture the bearing of bottom flange on to the concrete, the line element of plan size of solid equal to the cross section of line elements is connected between solid and shell elements below for bottom flange and above for top flange. (5) As the concrete cannot resist tension at the interface (i.e., between structural steel and RCC), the tensile stiffness is assigned as zero and only compressive stiffness is enabled to take.

Vacuum glazing consists of two or more glass panes hermetically sealed together around the edge with a vacuum gap between the panes. To avoid the glass panes from collapsing and touching each other under the influence of atmospheric pressure an array of support pillars is provided between the glass panes. A high level of thermal insulation is achieved by evacuating the spaces between the glass panes to a very low pressure which greatly reduces conduction and convection within the space; therefore heat transfer through this kind of glazing is significantly lower when compared with conventional insulating glazing. However, vacuum glazing is subject to inherent stresses due to atmospheric pressure and temperature differentials which can lead to fracture of the glass panes and failure of the edge seal. A flexible edge seal has been proposed to minimise the impact of these issues. In this paper, vacuum glazing system with rigid and flexible edge seals is theoretically studied and their advantages and disadvantages are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flexible%20edge%20seal" title="flexible edge seal">flexible edge seal</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a>, <a href="https://publications.waset.org/abstracts/search?q=support%20pillar" title=" support pillar"> support pillar</a>, <a href="https://publications.waset.org/abstracts/search?q=vacuum%20glazing" title=" vacuum glazing"> vacuum glazing</a> </p> <a href="https://publications.waset.org/abstracts/72593/theoretical-study-of-flexible-edge-seals-for-vacuum-glazing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72593.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">234</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">819</span> Extraction of Road Edge Lines from High-Resolution Remote Sensing Images Based on Energy Function and Snake Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zuoji%20Huang">Zuoji Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Haiming%20Qian"> Haiming Qian</a>, <a href="https://publications.waset.org/abstracts/search?q=Chunlin%20Wang"> Chunlin Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinyan%20Sun"> Jinyan Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Nan%20Xu"> Nan Xu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the strategy to extract double road edge lines from acquired road stripe image was explored. The workflow is as follows: the road stripes are acquired by probabilistic boosting tree algorithm and morphological algorithm immediately, and road centerlines are detected by thinning algorithm, so the initial road edge lines can be acquired along the road centerlines. Then we refine the results with big variation of local curvature of centerlines. Specifically, the energy function of edge line is constructed by gradient feature and spectral information, and Dijkstra algorithm is used to optimize the initial road edge lines. The Snake model is constructed to solve the fracture problem of intersection, and the discrete dynamic programming algorithm is used to solve the model. After that, we could get the final road network. Experiment results show that the strategy proposed in this paper can be used to extract the continuous and smooth road edge lines from high-resolution remote sensing images with an accuracy of 88% in
