The kinematics of deformations of the multiferroic doubly curved shell is described by a layer-wise shear deformation theory. A three-dimensional finite element model of multiferroic shells has been developed taking into account the electro-elastic and magneto-elastic couplings. A simple velocity feedback control law is employed to incorporate the active damping. Influence of layer stacking sequence and boundary conditions on the response of the multiferroic doubly curved shell has been studied. In addition, for the different orientation of the fibers of the constraining layer, the performance of the ACLD treatment has been studied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20constrained%20layer%20damping%20%28ACLD%29" title="active constrained layer damping (ACLD)">active constrained layer damping (ACLD)</a>, <a href="https://publications.waset.org/abstracts/search?q=doubly%20curved%20shells" title=" doubly curved shells"> doubly curved shells</a>, <a href="https://publications.waset.org/abstracts/search?q=magneto-electro-elastic" title=" magneto-electro-elastic"> magneto-electro-elastic</a>, <a href="https://publications.waset.org/abstracts/search?q=multiferroic%20composite" title=" multiferroic composite"> multiferroic composite</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20structures" title=" smart structures"> smart structures</a> </p> <a href="https://publications.waset.org/abstracts/61791/active-control-of-multiferroic-composite-shells-using-1-3-piezoelectric-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61791.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">311</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">713</span> Dynamic Response of Doubly Curved Composite Shell with Embedded Shape Memory Alloys Wires</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amin%20Ardali">Amin Ardali</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Khalili"> Mohammadreza Khalili</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Rezai"> Mohammadreza Rezai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, dynamic response of thin smart composite panel subjected to low-velocity transverse impact is investigated. Shape memory wires are used to reinforced curved composite panel in a smart way. One-dimensional thermodynamic constitutive model by Liang and Rogers is used for estimating the structural recovery stress. The two degrees-of-freedom mass-spring model is used for evaluation of the contact force between the curved composite panel and the impactor. This work is benefited from the Hertzian linear contact model which is linearized for the impact analysis of curved composite panel. The governing equations of curved panel are provided by first-order shear theory and solved by Fourier series related to simply supported boundary condition. For this purpose, the equation of doubly curved panel motion included the uniform in-plane forces is obtained. By the present analysis, the curved panel behavior under low-velocity impact, and also the effect of the impact parameters, the shape memory wire and the curved panel dimensions are studied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=doubly%20curved%20shell" title="doubly curved shell">doubly curved shell</a>, <a href="https://publications.waset.org/abstracts/search?q=SMA%20wire" title=" SMA wire"> SMA wire</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20response" title=" impact response"> impact response</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20material" title=" smart material"> smart material</a>, <a href="https://publications.waset.org/abstracts/search?q=shape%20memory%20alloy" title=" shape memory alloy"> shape memory alloy</a> </p> <a href="https://publications.waset.org/abstracts/49593/dynamic-response-of-doubly-curved-composite-shell-with-embedded-shape-memory-alloys-wires" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49593.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">712</span> Dynamic Analysis of Composite Doubly Curved Panels with Variable Thickness</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20Algul">I.

Panels with variable thickness are used in the construction of aerospace and marine industry. Giving variable thickness to panels can allow the designer to get optimum structural efficiency. For this reason, estimating the response of variable thickness panels is very important to design more reliable structures under dynamic loads. Dynamic equations for composite panels with variable thickness are obtained using virtual work principle. Partial derivatives in the equation of motion are expressed with GDQ and Newmark average acceleration scheme is used for temporal discretization. Several examples are used to highlight the effectiveness of the proposed method. Results are compared with finite element method.

Delamination tips are mostly captured by spatial numerical models in order to predict crack growth. This paper presents some mechanical models of delaminated composite shells based on shallow shell theories. The mechanical fields are based on a third-order displacement field in terms of the through-thickness coordinate of the laminated shell. The undelaminated and delaminated parts are captured by separate models and the continuity and boundary conditions are also formulated in a general way providing a large size boundary value problem. The system of differential equations is solved by the state space method for an elliptic delaminated shell having simply supported edges. The comparison of the proposed and a numerical model indicates that the primary indicator of the model is the deflection, the secondary is the widthwise distribution of the energy release rate. The model is promising and suitable to determine accurately the J-integral distribution along the delamination front. Based on the proposed model it is also possible to develop finite elements which are able to replace the computationally expensive spatial models of delaminated structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=J-integral" title="J-integral">J-integral</a>, <a href="https://publications.waset.org/abstracts/search?q=levy%20method" title=" levy method"> levy method</a>, <a href="https://publications.waset.org/abstracts/search?q=third-order%20shell%20theory" title=" third-order shell theory"> third-order shell theory</a>, <a href="https://publications.waset.org/abstracts/search?q=state%20space%20solution" title=" state space solution"> state space solution</a> </p> <a href="https://publications.waset.org/abstracts/110163/analytical-solution-of-the-boundary-value-problem-of-delaminated-doubly-curved-composite-shells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110163.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">131</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">710</span> Inequality for Doubly Warped Product Manifolds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Morteza%20Faghfouri">Morteza Faghfouri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper we establish a general inequality involving the Laplacian of the warping functions and the squared mean curvature of any doubly warped product isometrically immersed in a Riemannian manifold. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=integral%20submanifolds" title="integral submanifolds">integral submanifolds</a>, <a href="https://publications.waset.org/abstracts/search?q=S-space%20forms" title=" S-space forms"> S-space forms</a>, <a href="https://publications.waset.org/abstracts/search?q=doubly%20warped%20product" title=" doubly warped product"> doubly warped product</a>, <a href="https://publications.waset.org/abstracts/search?q=inequality" title=" inequality"> inequality</a> </p> <a href="https://publications.waset.org/abstracts/9822/inequality-for-doubly-warped-product-manifolds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9822.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">288</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">709</span> Failure Mechanism of Slip-Critical Connections on Curved Surface</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bae%20Doobyong">Bae Doobyong</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoo%20Jaejun"> Yoo Jaejun</a>, <a href="https://publications.waset.org/abstracts/search?q=Park%20Ilgyu"> Park Ilgyu</a>, <a href="https://publications.waset.org/abstracts/search?q=Choi%20Seowon"> Choi Seowon</a>, <a href="https://publications.waset.org/abstracts/search?q=Oh%20Chang%20Kook"> Oh Chang Kook</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Variation of slip coefficient in slip-critical connections of curved plates.

The optimization is based on elastic-plastic geometrically nonlinear incremental-iterative finite element analysis. The nine-node degenerated curved shell element is used in which five degrees of freedom are specified at each nodal point, with a layered model. The formulation of the geometrical nonlinearity problem is carried out using the well-known total Lagrangian principle. For the structural optimization problem, which is dealt with as a constrained nonlinear optimization, the so-called Modified Hooke and Jeeves method is employed by considering the weight of the shell as the objective function with stress and geometrical constraints. It was concluded that the optimum design of composite sandwich cylindrical shell that have a rigid polyurethane foam core and steel facing occurs when the area covered by the shell becomes almost square with a ratio of core thickness to facing thickness lies between 45 and 49, while the optimum height to length ration varies from 0.03 to 0.08 depending on the aspect ratio of the shell and its boundary conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20structure" title="composite structure">composite structure</a>, <a href="https://publications.waset.org/abstracts/search?q=cylindrical%20shell" title=" cylindrical shell"> cylindrical shell</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=non-linear%20analysis" title=" non-linear analysis"> non-linear analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element" title=" finite element"> finite element</a> </p> <a href="https://publications.waset.org/abstracts/11228/optimal-design-of-composite-cylindrical-shell-based-on-nonlinear-finite-element-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11228.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">391</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">707</span> Study on Multi-Point Stretch Forming Process for Double Curved Surface</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiwoo%20Park">Jiwoo Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Junseok%20Yoon"> Junseok Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeong%20Kim"> Jeong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Beomsoo%20Kang"> Beomsoo Kang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Multi-Point Stretch Forming (MPSF) process is suitable for flexible manufacturing, and it has several advantages including that it could be applied to various forming such as sheet metal forming, single curved surface forming and double curved one. In this study, a systematic numerical simulation was carried out for atypical double curved surface forming using the multiple die stretch forming process. In this simulation, urethane pads were defined based on hyper-elastic material model as a cushion for the smooth forming surface. The deformation behaviour on elastic recovery was also investigated to consider the exact result after the last forming process, and then the experiment was also carried out to confirm the formability of this forming process. By comparing the simulation and experiment results, the suitability of the multiple die stretch forming process for the atypical double curved surface was verified. Consequently, it is confirmed that the multi-point stretch forming process has the capability and feasibility of being used to manufacture the double curved surfaces of sheet metal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multi-point%20stretch%20forming" title="multi-point stretch forming">multi-point stretch forming</a>, <a href="https://publications.waset.org/abstracts/search?q=double%20curved%20surface" title=" double curved surface"> double curved surface</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=manufacturing" title=" manufacturing"> manufacturing</a> </p> <a href="https://publications.waset.org/abstracts/7221/study-on-multi-point-stretch-forming-process-for-double-curved-surface" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7221.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">480</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">706</span> Modeling Thin Shell Structures by a New Flat Shell Finite Element</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Djamal%20Hamadi">Djamal Hamadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20Ayoub"> Ashraf Ayoub</a>, <a href="https://publications.waset.org/abstracts/search?q=Ounis%20Abdelhafid"> Ounis Abdelhafid</a>, <a href="https://publications.waset.org/abstracts/search?q=Chebili%20Rachid"> Chebili Rachid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a new computationally-efficient rectangular flat shell finite element named 'ACM_RSBEC' is presented.

Prior work done by Mahadev and Chan focused on formulating a modified composite shell theory based prognosis methodology for investigating the structural response of thin-walled circular cylindrical shell type composite configurations under in-plane mechanical loads respectively. The prime motivation to develop this theory stemmed from its capability to generate simple yet accurate closed-form analytical results that can efficiently characterize circular composite shell construction. It showcased the development of a novel mathematical framework to analytically identify the location of the centroid for thin-walled, open cross-section, curved composite shells that were characterized by circumferential arc angle, thickness-to-mean radius ratio, and total laminate thickness. Ply stress variations for curved cylindrical shells were analytically examined under the application of centric tensile and bending loading. This work presents a cost-effective, small-platform experimental methodology by taking advantage of the full-field measurement capability of digital image correlation (DIC) for an accurate assessment of key mechanical parameters such as in-plane mechanical stresses and strains, centroid location etc. Mechanical property measurement of advanced composite materials can become challenging due to their anisotropy and complex failure mechanisms. Full-field displacement measurements are well suited for characterizing the mechanical properties of composite materials because of the complexity of their deformation. This work encompasses the fabrication of a set of curved cylindrical shell coupons, the design and development of a novel test-fixture design and an innovative experimental methodology that demonstrates the capability to very accurately predict the location of centroid in such curved composite cylindrical strips via employing a DIC based strain measurement technique. Error percentage difference between experimental centroid measurements and previously estimated analytical centroid results are observed to be in good agreement. The developed analytical modified-shell theory provides the capability to understand the fundamental behavior of thin-walled cylindrical shells and offers the potential to generate novel avenues to understand the physics of such structures at a laminate level. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anisotropy" title="anisotropy">anisotropy</a>, <a href="https://publications.waset.org/abstracts/search?q=composites" title=" composites"> composites</a>, <a href="https://publications.waset.org/abstracts/search?q=curved%20cylindrical%20shells" title=" curved cylindrical shells"> curved cylindrical shells</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20image%20correlation" title=" digital image correlation"> digital image correlation</a> </p> <a href="https://publications.waset.org/abstracts/80831/digital-image-correlation-based-mechanical-response-characterization-of-thin-walled-composite-cylindrical-shells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80831.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">316</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">704</span> Generation of Mesoporous Silica Shell onto SSZ-13 and Its Effects on Methanol to Olefins</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ying%20Weiyong">Ying Weiyong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The micro/mesoporous core-shell composites compromising SSZ-13 cores and mesoporous silica shells were synthesized successfully with the soft template of cetytrimethylammonium.

The acidity intensity of the strong acid sites on SSZ-13 was remarkably impaired with the decoration of the mesoporous silica shell, which leads to the suppression of the hydrogen transfer reaction in MTO reaction.

We derive the aperture field delay to form a caustic of rays along the beam axis and extend this method to other points over the aperture. In the second approach, we harness the proven capabilities of beam methods to address the challenge of designing curved intensity profiles in three-dimensional free space. By leveraging advanced beam propagation techniques, we create and manipulate complex intensity patterns along arbitrarily curved trajectories, offering additional possibilities for precision control in various wave-based applications.

Since the actual bogie hunting motion, occurring for real railway vehicles running on straight rails at high travelling speeds, cannot be obtained in laboratory conditions, due to the speed and wavelength limitations, a pseudo- hunting motion was induced by employing double-curved rails. Firstly, the test rig and the experimental procedure are described. Then, a geometrical model of the double-curved rails is presented. Based on such model, the variation of the carriage rotation angle relative to the bogies and the working conditions of the yaw damper are clarified. Vibration spectra recorded during vehicle travelling, on straight and double-curved rails, are presented and interpreted based on a simple vibration model of the railway vehicle. Ride comfort of the vehicle is evaluated according to the ISO 2631 standard, and also by using some particular frequency weightings, which account for the discomfort perceived during the reading and writing activities. Results obtained in this work are useful for the adequate design of the yaw dampers, which are used to attenuate the lateral vibration of the train car bodies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=double-curved%20rail" title="double-curved rail">double-curved rail</a>, <a href="https://publications.waset.org/abstracts/search?q=octave%20analysis" title=" octave analysis"> octave analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=vibration%20model" title=" vibration model"> vibration model</a>, <a href="https://publications.waset.org/abstracts/search?q=ride%20comfort" title=" ride comfort"> ride comfort</a>, <a href="https://publications.waset.org/abstracts/search?q=railway%20vehicle" title=" railway vehicle"> railway vehicle</a> </p> <a href="https://publications.waset.org/abstracts/54593/investigation-on-the-bogie-pseudo-hunting-motion-of-a-reduced-scale-model-railway-vehicle-running-on-double-curved-rails" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54593.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">316</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">694</span> The Effect of Arbitrary Support Conditions on the Static Behavior of Curved Beams Using the Finite Element Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Mottaghi%20T.">Hossein Mottaghi T.</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20R.%20Masoodi"> Amir R.

Subsequently, nodal interpolation functions for this element are derived, followed by the construction of the element stiffness matrix. To enable the utilization of the stiffness matrix in the static analysis of curved beams, the constructed matrix in the local coordinates of the element is transformed to the global coordinate system using the rotation matrix. A numerical benchmark example is investigated to assess the accuracy and effectiveness of this method. Moreover, the influence of spring stiffness on the rotation of the endpoint of a clamped beam is examined by substituting each support reaction of the beam with a spring. In the parametric study, the effect of the central angle of the beam on the rotation of the beam's endpoint in a cantilever beam under a concentrated load is examined. This research encompasses various mechanical, geometrical, and boundary configurations to evaluate the static characteristics of curved beams, thus providing valuable insights for their analysis and examination. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=curved%20beam" title="curved beam">curved beam</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=first-order%20shear%20deformation%20theory" title=" first-order shear deformation theory"> first-order shear deformation theory</a>, <a href="https://publications.waset.org/abstracts/search?q=elastic%20support" title=" elastic support"> elastic support</a> </p> <a href="https://publications.waset.org/abstracts/186836/the-effect-of-arbitrary-support-conditions-on-the-static-behavior-of-curved-beams-using-the-finite-element-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186836.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">70</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">693</span> Research on Static and Dynamic Behavior of New Combination of Aluminum Honeycomb Panel and Rod Single-Layer Latticed Shell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xu%20Chen">Xu Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhao%20Caiqi"> Zhao Caiqi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In addition to the advantages of light weight, resistant corrosion and ease of processing, aluminum is also applied to the long-span spatial structures.

The demands of timbers in Indonesia is more increasing compared to its supply from natural forest. It is associated with the issues of global warming and environmental preservation. The uses of timbers from HTI (Industrial Planting Forest) and HTR (Society Planting Forest), such as Jabon, is an alternative source that required to solve these problems. Having shorter lifespan is the benefit of HTI/HTR timbers, although they are relatively smaller in dimension and lower in strength. Engineering Wood Product (EWP) such as glulam (glue-laminated) timber, is required to overcome their losses. Glulam is fabricated by gluing the wooden planks that having a thickness of 20 to 45 mm with an adhesive material and a certain pressure. Glulam can be made a curved beam, is one of the advantages, thus making it strength is greater than a straight beam. This paper is aimed to know the material behavior of curved glue-laminated beam of Jabon timber. Preliminary methods was to gain physical and mechanical properties, and glue spread strength of Jabon timber, which following the ASTM D-143 standard test method. Dimension of beams were 50 mm wide, 760 mm span, 50 mm thick, and 50 mm rise. Each layer of Jabon has a thickness of 5 mm and is glued with polyurethane. Cold press will be applied to beam laminated specimens for more than 5 hours. The curved glue-laminated beams specimens will be tested about the bending behavior. This experiments aims to obtain the increasing of load carrying capacity and stiffness of curved glulam beam. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=curved%20glulam%20beam" title="curved glulam beam">curved glulam beam</a>, <a href="https://publications.waset.org/abstracts/search?q=HTR%26HTI" title=" HTR&HTI"> HTR&HTI</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20carrying" title=" load carrying"> load carrying</a>, <a href="https://publications.waset.org/abstracts/search?q=strength" title=" strength"> strength</a> </p> <a href="https://publications.waset.org/abstracts/39701/the-material-behavior-in-curved-glulam-beam-of-jabon-timber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39701.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">298</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">689</span> Shell Lime: An Eco-Friendly and Cost-Efficient Alternative for Agricultural Lime</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hene%20L.%20Hapinat">Hene L.

The hydrogen ion concentration (pH) and the lime concentration using Calcium Carbonate Equivalent (CCE) of each shellfish species were measured and tested for the enhancement of an acidic soil. The experiment was laid out in a Completely Randomized Design (CRD) with 4 treatments replicated 3 times. The treatments were as follows: Treatment A- 100 g agricultural lime; B- 100 g oyster shell lime; C- 100 g turret shell lime; and D- 100 g mangrove clam shell lime. Each treatment was combined to the acidic soil sample. The results were statistically analyzed using One-way Analysis of Variance (ANOVA) and Least Square Difference (LSD) at 0.01 and 0.05 levels of significance.

The result of the research: There were 4 main results from the study. Firstly, most of the manufacturer of coconut-shell product is usually owned by a single owner and the quantity of the finished product is quite low and the main labor group is local people. Secondly, the production process can be divided into 4 stages which are pre-production process, production process, packaging process and distribution process. Thirdly, each 3 of the logistics process of coconut shell will find process which may cause the problem to the business but the process which finds the most problem is the production process because the production process needs the skilled labor and the quantity of the labor does not match with the demand from the customers. Lastly, the factors which affect the production process of the coconut shell can be founded in almost every process of the process such as production design, packaging design, sourcing supply and distribution management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=production%20process" title="production process">production process</a>, <a href="https://publications.waset.org/abstracts/search?q=coconut-shell%20product" title=" coconut-shell product"> coconut-shell product</a>, <a href="https://publications.waset.org/abstracts/search?q=Amphawa%20District" title=" Amphawa District"> Amphawa District</a>, <a href="https://publications.waset.org/abstracts/search?q=inbound%20logistics%20process" title=" inbound logistics process"> inbound logistics process</a> </p> <a href="https://publications.waset.org/abstracts/14646/production-process-of-coconut-shell-product-in-amphawa-district" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14646.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">522</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">687</span> A Novel Fuzzy Second-Order Sliding Mode Control of a Doubly Fed Induction Generator for Wind Energy Conversion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elhadj%20Bounadja">Elhadj Bounadja</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohand%20Oulhadj%20Mahmoudi"> Mohand Oulhadj Mahmoudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelkader%20Djahbar"> Abdelkader Djahbar</a>, <a href="https://publications.waset.org/abstracts/search?q=Zinelaabidine%20Boudjema"> Zinelaabidine Boudjema</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper we present a novel fuzzy second-order sliding mode control (FSOSMC) for wind energy conversion system based on a doubly-fed induction generator (DFIG).
