Theis approach can be applied to very complex 3D meshes of arbitrary topology and with millions of vertices. The algorithm is based on the clustering of the input mesh elements, which divides the faces of an input mesh into a given number of clusters for clustering purpose by approximating the Centroidal Voronoi Tessellation of the input mesh. Once a clustering is achieved, it provides us an efficient way to construct uniform tessellations, and therefore leads to good coarsening of polygonal meshes. With proliferation of 3D scanners, this coarsening algorithm is particularly useful for reverse engineering applications of 3D models, which in many cases are dense, non-uniform, irregular and arbitrary topology. Examples demonstrating effectiveness of the new algorithm are also included in the paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coarsening" title="coarsening">coarsening</a>, <a href="https://publications.waset.org/abstracts/search?q=mesh%20clustering" title=" mesh clustering"> mesh clustering</a>, <a href="https://publications.waset.org/abstracts/search?q=shape%20approximation" title=" shape approximation"> shape approximation</a>, <a href="https://publications.waset.org/abstracts/search?q=mesh%20simplification" title=" mesh simplification"> mesh simplification</a> </p> <a href="https://publications.waset.org/abstracts/48919/3d-mesh-coarsening-via-uniform-clustering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48919.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">380</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">473</span> The Design and Implementation of an Enhanced 2D Mesh Switch</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manel%20Langar">Manel Langar</a>, <a href="https://publications.waset.org/abstracts/search?q=Riad%20Bourguiba"> Riad Bourguiba</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaouhar%20Mouine"> Jaouhar Mouine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we propose the design and implementation of an enhanced wormhole virtual channel on chip router.

We use a quadric error metric to calculate an error value for each vertex of the mesh and order all vertices based on this value. This step is followed by the parallel removal of a number of vertices with the lowest calculated error values. To allow for the parallel removal of multiple vertices we use a set of per-vertex boundaries that prevent mesh foldovers even when simplification operations are performed on neighbouring vertices. We execute multiple iterations of the calculation of the vertex errors, ordering of the error values and removal of vertices until either a desired number of vertices remains in the mesh or a minimum error value is reached. This parallel approach is used to speed up the simplification process while maintaining mesh topology and avoiding foldovers at every step of the simplification. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computer%20graphics" title="computer graphics">computer graphics</a>, <a href="https://publications.waset.org/abstracts/search?q=half%20edge%20collapse" title=" half edge collapse"> half edge collapse</a>, <a href="https://publications.waset.org/abstracts/search?q=mesh%20simplification" title=" mesh simplification"> mesh simplification</a>, <a href="https://publications.waset.org/abstracts/search?q=precomputed%20simplification" title=" precomputed simplification"> precomputed simplification</a>, <a href="https://publications.waset.org/abstracts/search?q=topology%20preserving" title=" topology preserving"> topology preserving</a> </p> <a href="https://publications.waset.org/abstracts/36600/gpu-accelerated-triangle-mesh-simplification-using-parallel-vertex-removal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36600.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">367</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">471</span> Pathology of Explanted Transvaginal Meshes </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vladimir%20V.%20Iakovlev">Vladimir V.

Ludwig</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A transient model for nozzle clogging has been developed and successfully validated against a laboratory experiment. Key steps of clogging are considered: transport of particles by turbulent flow towards the nozzle wall; interactions between fluid flow and nozzle wall, and the adhesion of the particle on the wall; the growth of the clog layer and its interaction with the flow. The current paper is to investigate the mesh (size and type) sensitivity of the model in both two and three dimensions. It is found that the algorithm for clog growth alone excluding the flow effect is insensitive to the mesh type and size, but the calculation including flow becomes sensitive to the mesh quality. The use of 2D meshes leads to overestimation of the clog growth because the 3D nature of flow in the boundary layer cannot be properly solved by 2D calculation. 3D simulation with tetrahedron mesh can also lead to an error estimation of the clog growth. A mesh-independent result can be achieved with hexahedral mesh, or at least with triangular prism (inflation layer) for near-wall regions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clogging" title="clogging">clogging</a>, <a href="https://publications.waset.org/abstracts/search?q=continuous%20casting" title=" continuous casting"> continuous casting</a>, <a href="https://publications.waset.org/abstracts/search?q=inclusion" title=" inclusion"> inclusion</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=submerged%20entry%20nozzle" title=" submerged entry nozzle"> submerged entry nozzle</a> </p> <a href="https://publications.waset.org/abstracts/74984/investigation-on-mesh-sensitivity-of-a-transient-model-for-nozzle-clogging" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74984.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">283</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">469</span> A Novel Gateway Location Algorithm for Wireless Mesh Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20M.%20Komba">G.

Choosing strategic locations for the Internet Gateways (IGWs) best location in Backbone Wireless Mesh (BWM) precarious to the Wireless Mesh Network (WMN) and the location of IGW can improve a quantity of performance related problem. In this paper, we propose a novel algorithm, namely New Gateway Location Algorithm (NGLA), which aims to achieve four objectives, decreasing the network cost effective, minimizing delay, optimizing the throughput capacity, Different from existing algorithms, the NGLA increasingly recognizes IGWs, allocates mesh routers (MRs) to identify IGWs and promises to ﬁnd a feasible IGW location and install minimum as possible number of IGWs while regularly conserving the all Quality of Service (QoS) requests. Simulation results showing that the NGLA outperforms other different algorithms by comparing the number of IGWs with a large margin and it placed 40% less IGWs and 80% gain of throughput. Furthermore the NGLA is easy to implement and could be employed for BWM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wireless%20Mesh%20Network" title="Wireless Mesh Network">Wireless Mesh Network</a>, <a href="https://publications.waset.org/abstracts/search?q=Gateway%20Location%20Algorithm" title=" Gateway Location Algorithm"> Gateway Location Algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=Quality%20of%20Service" title=" Quality of Service"> Quality of Service</a>, <a href="https://publications.waset.org/abstracts/search?q=BWM" title=" BWM"> BWM</a> </p> <a href="https://publications.waset.org/abstracts/15679/a-novel-gateway-location-algorithm-for-wireless-mesh-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15679.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">370</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">468</span> Routing Metrics and Protocols for Wireless Mesh Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samira%20Kalantary">Samira Kalantary</a>, <a href="https://publications.waset.org/abstracts/search?q=Zohre%20Saatzade"> Zohre Saatzade</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wireless Mesh Networks (WMNs) are low-cost access networks built on cooperative routing over a backbone composed of stationary wireless routers.

A new technique is known as intraabdominal mesh transplant that give better protection for herniorrhaphy. The aim of this study was to determine the performance of hernia mesh. In this study, an efficacy of two synthetic hernia mesh implants viz. conventional Prolene and a lightweight mesh monofilament polyester were assessed for the abdominal wall repair in pigeons. Twenty four healthy pigeons were selected and randomly distributed into three groups, A, B and C (n=8). In all groups, experimental laparotomy was performed; thereafter, abdominal muscles and peritoneum were sutured together, while, a 2 x 2 cm defect was created in the abdominal muscles. For onlay hernioplasty, the hernia mesh (Prolene mesh: group A; Polyester mesh: group B) was implanted over the external oblique muscles of the abdomen. In group C (control), the mesh was not implanted; instead, the laparotomy incision was closed after a herniorrhaphy. Post-operative pain wound healing, adhesion formation, histopathological findings and formation of hematoma, abscess and seroma were assessed as short-term complications. Post-operatively, pain at surgical site was significantly less (P < 0.001) in group B (Polyester mesh); wound healing was also significantly better and rapid in group B (P < 0.05) than in group A (Prolene mesh). Group B (Polyester mesh) also depicted less than 25% adhesions when assessed on the basis of a Quantitative Modified Diamond scale; a Qualitative Adhesion Tenacity scale also depicted either no adhesions or flimsy adhesions (n=2) in group B (Polyester mesh), in contrast to group A (Prolene), which manifested greater adhesion formation and presence of dense adhesions requiring blunt dissection. There were observed hematoma, seroma and abscess formations in birds treated by Prolene mesh only. Conclusively, the polyester mesh proved superior to the Prolene mesh regarding lesser adhesion, better in wound healing, and no short-term follow-up complications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adhesion" title="adhesion">adhesion</a>, <a href="https://publications.waset.org/abstracts/search?q=mesh" title=" mesh"> mesh</a>, <a href="https://publications.waset.org/abstracts/search?q=polyester" title=" polyester"> polyester</a>, <a href="https://publications.waset.org/abstracts/search?q=prolene" title=" prolene"> prolene</a> </p> <a href="https://publications.waset.org/abstracts/99546/comparative-efficacy-of-prolene-and-polyester-mesh-for-the-repair-of-abdominal-wall-defect-in-pigeons-columba-livia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99546.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">247</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">466</span> Experimental Study to Determine the Effect of Wire Mesh Pore Size on Natural Draft Chimney Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Md.%20Mizanur%20Rahman">Md.

The increased demand of energy helps to restart to think about the efficiency of chimney as well as to find out a valid option to replace forced draft chimney system from industries. In this study natural draft chimney model is air flow rate; exit air temperature and pressure losses are studied through modification with wire mesh screen and compare the results with without wire mesh screen chimney model. The heat load is varies from 0.1 kW to 1kW and three different wire mesh screens that have pore size 0.15 mm2, 0.40 mm2 and 4.0 mm2 respectively are used. The experimental results show that natural draft chimney model with wire mesh screens significantly restored the flow losses compared to the system without wire mesh screen. The natural draft chimney model with 0.40 mm2 pore size wire mesh screen can minimize the draft losses better than others and able to enhance velocity about 54 % exit air temperature about 41% and pressure loss decreased by about 20%. Therefore, it can be decided that the wire mesh screens significantly minimize the draft losses in the natural draft chimney and 0.40 mm2 pore size screen will be a suitable option. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=natural%20draft%20dhimney" title="natural draft dhimney">natural draft dhimney</a>, <a href="https://publications.waset.org/abstracts/search?q=wire%20mesh%20screen" title=" wire mesh screen"> wire mesh screen</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20draft%20flow" title=" natural draft flow"> natural draft flow</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20engineering" title=" mechanical engineering"> mechanical engineering</a> </p> <a href="https://publications.waset.org/abstracts/29139/experimental-study-to-determine-the-effect-of-wire-mesh-pore-size-on-natural-draft-chimney-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29139.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">319</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">465</span> An Efficient Resource Management Algorithm for Mobility Management in Wireless Mesh Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mallikarjuna%20Rao%20Yamarthy">Mallikarjuna Rao Yamarthy</a>, <a href="https://publications.waset.org/abstracts/search?q=Subramanyam%20Makam%20Venkata"> Subramanyam Makam Venkata</a>, <a href="https://publications.waset.org/abstracts/search?q=Satya%20Prasad%20Kodati"> Satya Prasad Kodati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objective of the proposed work is to reduce the overall network traffic incurred by mobility management, packet delivery cost and to increase the resource utilization. The proposed algorithm, An Efficient Resource Management Algorithm (ERMA) for mobility management in wireless mesh networks, relies on pointer based mobility management scheme. Whenever a mesh client moves from one mesh router to another, the pointer is set up dynamically between the previous mesh router and current mesh router based on the distance constraints.

However, it still suffers from the limited deformation ability, especially in large deformation. In this paper, a pre-displacement improvement is proposed to improve the problem that illegal meshes always appear near the moving inner boundaries owing to the large relative displacement of the nodes near inner boundaries. In this improvement, nodes near the inner boundaries are first associated to the near boundary nodes, and a pre-displacement based on the displacements of associated boundary nodes is added to the nodes near boundaries in order to make the displacement closer to the boundary deformation and improve the deformation capability. Several 2D and 3D numerical simulation cases have shown that the pre-displacement improvement for radial basis function (RBF) method significantly improves the mesh quality near inner boundaries and deformation capability, with little computational burden increasement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mesh%20deformation" title="mesh deformation">mesh deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=mesh%20quality" title=" mesh quality"> mesh quality</a>, <a href="https://publications.waset.org/abstracts/search?q=background%20mesh" title=" background mesh"> background mesh</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20basis%20function" title=" radial basis function"> radial basis function</a> </p> <a href="https://publications.waset.org/abstracts/65928/an-improved-mesh-deformation-method-based-on-radial-basis-function" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65928.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">366</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">463</span> Effect of Mesh Size on the Supersonic Viscous Flow Parameters around an Axisymmetric Blunt Body</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haoui%20Rabah">Haoui Rabah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this work is to analyze a viscous flow around the axisymmetric blunt body taken into account the mesh size both in the free stream and into the boundary layer.

The numerical technique uses the Flux Vector Splitting method of Van Leer. Here, adequate time stepping parameter, CFL coefficient and mesh size level are selected to ensure numerical convergence. The effect of the mesh size is significant on the shear stress and velocity profile. The best solution is obtained with using a very fine grid.

This paper investigates whether flexible cystoscopy is an essential diagnostic and therapeutic tool in managing such patients. With the increasing prevalence of mesh-related complications, it is crucial to explore how diagnostic procedures like cystoscopy can aid in identifying mesh-associated issues that contribute to recurrent UTIs. While flexible cystoscopy is commonly used to evaluate lower urinary tract conditions, its necessity in cases involving patients with mesh implants remains under debate. This study aims to determine the value of flexible cystoscopy in identifying complications such as mesh erosion, fistula formation, and chronic inflammation, which may contribute to recurrent infections. The research compares patients who underwent flexible cystoscopy to those managed without this procedure, examining the diagnostic yield of cystoscopy in detecting mesh-related complications. Furthermore, the study investigates the relationship between recurrent UTIs and the mechanical effects of mesh on the urinary tract, as well as the potential for cystoscopy to guide treatment decisions, such as mesh removal or revision. The results indicate that while flexible cystoscopy can identify mesh-related complications in some cases, its routine use may not be necessary for all patients with recurrent UTIs and mesh. The study emphasizes the importance of patient selection, clinical history, and symptom severity in deciding whether to employ cystoscopy. In cases where there are clear signs of mesh erosion or unexplained recurrent infections despite standard treatments, cystoscopy proves valuable. However, the study also highlights potential risks and discomfort associated with the procedure, suggesting that cystoscopy should be reserved for select cases where non-invasive methods fail to provide clarity. The research concludes that while flexible cystoscopy remains a valuable tool in certain cases, its routine use for all patients with recurrent UTIs and mesh is not justified. The paper provides recommendations for clinical guidelines, emphasizing a more personalized approach to diagnostics that considers the patient’s overall condition, infection history, and mesh type. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flexible%20cystoscopy" title="flexible cystoscopy">flexible cystoscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=recurrent%20urinary%20tract%20infections" title=" recurrent urinary tract infections"> recurrent urinary tract infections</a>, <a href="https://publications.waset.org/abstracts/search?q=mesh%20implants" title=" mesh implants"> mesh implants</a>, <a href="https://publications.waset.org/abstracts/search?q=mesh%20erosion" title=" mesh erosion"> mesh erosion</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnostic%20procedures" title=" diagnostic procedures"> diagnostic procedures</a>, <a href="https://publications.waset.org/abstracts/search?q=urology" title=" urology"> urology</a> </p> <a href="https://publications.waset.org/abstracts/192383/the-role-of-flexible-cystoscopy-in-managing-recurrent-urinary-tract-infections-in-patients-with-mesh-implants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192383.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">18</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">461</span> An Investigation into the Use of Overset Mesh for a Vehicle Aerodynamics Case When Driving in Close Proximity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kushal%20Kumar%20Chode">Kushal Kumar Chode</a>, <a href="https://publications.waset.org/abstracts/search?q=Remus%20Miahi%20Cirstea"> Remus Miahi Cirstea</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent times, the drive towards more efficient vehicles and the increase in the number of vehicle on the roads has driven the aerodynamic researchers from studying the vehicle in isolation towards understanding the benefits of vehicle platooning. Vehicle platooning is defined as a series of vehicles traveling in close proximity. Due to the limitations in size and load measurement capabilities for the wind tunnels facilities, it is very difficult to perform this investigation experimentally. In this paper, the use of chimera or overset meshing technique is used within the STARCCM+ software to model the flow surrounding two identical vehicle models travelling in close proximity and also during an overtaking maneuver.

However, mesh ﬁxation may increase surgical complications and postoperative pain. Our objective was to compare the outcomes of nonﬁxation with ﬁxation of polypropylene mesh by metal tacks during TEP repair of inguinal hernia. Methods: Forty patients aged 18 to72 years with inguinal hernia were included who underwent laparoscopic TEP repair of inguinal hernia with (n=20) or without (n=20) fixation of the mesh. The outcomes were operative duration, postoperative pain score, cost, in-hospital stay, time to return to normal activity, and complications. Results: Patients in whom the mesh was not fixed had shorter mean operating time (p < 0.05). We found no difference between groups in the postoperative pain score, incidence of recurrence, in-hospital stay, time to return to normal activity and complications (P > 0.05). Moreover, a net cost savings was realized for each hernia repair performed without stapled mesh. Conclusions: TEP repair without mesh fixation resulted in the shorter operating time and lower operative cost with no difference between groups in the postoperative pain score, incidence of recurrence, in-hospital stay, time to return to normal activity and complications. All this contribute to make TEP repair without mesh fixation a better choice for repair of uncomplicated inguinal hernia, especially in developing nations with scarce resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=postoperative%20pain%20score" title="postoperative pain score">postoperative pain score</a>, <a href="https://publications.waset.org/abstracts/search?q=inguinal%20hernia" title=" inguinal hernia"> inguinal hernia</a>, <a href="https://publications.waset.org/abstracts/search?q=nonfixation%20of%20mesh" title=" nonfixation of mesh"> nonfixation of mesh</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20extra%20peritoneal%20%28TEP%29" title=" total extra peritoneal (TEP)"> total extra peritoneal (TEP)</a> </p> <a href="https://publications.waset.org/abstracts/36490/comparative-study-of-outcomes-of-nonfixation-of-mesh-versus-fixation-in-laparoscopic-total-extra-peritoneal-tep-repair-of-inguinal-hernia-a-prospective-randomized-controlled-trial" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36490.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">343</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">459</span> Numerical Investigation of Wire Mesh Heat Pipe for Spacecraft Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jayesh%20Mahitkar">Jayesh Mahitkar</a>, <a href="https://publications.waset.org/abstracts/search?q=V.%20K.%20Singh"> V.

Since concrete subjected to impact loading associated with high strain rate shows quite different material behavior from that in the static state, several material models are proposed and used to describe the high strain rate behavior under blast and impact loading. In the process of modelling, in advance, mesh dependency in the used finite element (FE) is the key problem because simulation results under high strain-rate condition are quite sensitive to applied FE mesh size. It means that the accuracy of simulation results may deeply be dependent on FE mesh size in simulations. This paper introduces an improved criterion which can minimize the mesh-dependency of simulation results on the basis of the fracture energy concept, and HJC (Holmquist Johnson Cook), CSC (Continuous Surface Cap) and K&C (Karagozian & Case) models are examined to trace their relative sensitivity to the used FE mesh size. To coincide with the purpose of the penetration test with a concrete plate under a projectile (bullet), the residual velocities of projectile after penetration are compared. The correlation studies between analytical results and the parametric studies associated with them show that the variation of residual velocity with the used FE mesh size is quite reduced by applying a unique failure strain value determined according to the proposed criterion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high%20strain%20rate%20concrete" title="high strain rate concrete">high strain rate concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=penetration%20simulation" title=" penetration simulation"> penetration simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=failure%20strain" title=" failure strain"> failure strain</a>, <a href="https://publications.waset.org/abstracts/search?q=mesh-dependency" title=" mesh-dependency"> mesh-dependency</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture%20energy" title=" fracture energy"> fracture energy</a> </p> <a href="https://publications.waset.org/abstracts/18943/an-criterion-to-minimize-fe-mesh-dependency-in-concrete-plate-subjected-to-impact-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18943.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">520</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">456</span> An Inviscid Compressible Flow Solver Based on Unstructured OpenFOAM Mesh Format</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Utkan%20Caliskan">Utkan Caliskan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Two types of numerical codes based on finite volume method are developed in order to solve compressible Euler equations to simulate the flow through forward facing step channel. Both algorithms have AUSM+- up (Advection Upstream Splitting Method) scheme for flux splitting and two-stage Runge-Kutta scheme for time stepping. In this study, the flux calculations differentiate between the algorithm based on OpenFOAM mesh format which is called 'face-based' algorithm and the basic algorithm which is called 'element-based' algorithm. The face-based algorithm avoids redundant flux computations and also is more flexible with hybrid grids. Moreover, some of OpenFOAM’s preprocessing utilities can be used on the mesh. Parallelization of the face based algorithm for which atomic operations are needed due to the shared memory model, is also presented. For several mesh sizes, 2.13x speed up is obtained with face-based approach over the element-based approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cell%20centered%20finite%20volume%20method" title="cell centered finite volume method">cell centered finite volume method</a>, <a href="https://publications.waset.org/abstracts/search?q=compressible%20Euler%20equations" title=" compressible Euler equations"> compressible Euler equations</a>, <a href="https://publications.waset.org/abstracts/search?q=OpenFOAM%20mesh%20format" title=" OpenFOAM mesh format"> OpenFOAM mesh format</a>, <a href="https://publications.waset.org/abstracts/search?q=OpenMP" title=" OpenMP"> OpenMP</a> </p> <a href="https://publications.waset.org/abstracts/73005/an-inviscid-compressible-flow-solver-based-on-unstructured-openfoam-mesh-format" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73005.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">319</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">455</span> A Systematic Review Examining the Experimental methodology behind in vivo testing of hiatus hernia and Diaphragmatic Hernia Mesh</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Whitehead-Clarke%20T.">Whitehead-Clarke T.</a>, <a href="https://publications.waset.org/abstracts/search?q=Beynon%20V."> Beynon V.</a>, <a href="https://publications.waset.org/abstracts/search?q=Banks%20J."> Banks J.</a>, <a href="https://publications.waset.org/abstracts/search?q=Karanjia%20R."> Karanjia R.</a>, <a href="https://publications.waset.org/abstracts/search?q=Mudera%20V."> Mudera V.</a>, <a href="https://publications.waset.org/abstracts/search?q=Windsor%20A."> Windsor A.</a>, <a href="https://publications.waset.org/abstracts/search?q=Kureshi%20A."> Kureshi A.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Mesh implants are regularly used to help repair both hiatus hernias (HH) and diaphragmatic hernias (DH). In vivo studies are used to test not only mesh safety but increasingly comparative efficacy. Our work examines the field of in vivo mesh testing for HH and DH models to establish current practices and standards. Method: This systematic review was registered with PROSPERO. Medline and Embase databases were searched for relevant in vivo studies. 44 articles were identified and underwent abstract review, where 22 were excluded. 4 further studies were excluded after full text review – leaving 18 to undergo data extraction. Results: Of 18 studies identified, 9 used an in vivo HH model and 9 a DH model. 5 studies undertook mechanical testing on tissue samples – all uniaxial in nature. Testing strip widths ranged from 1-20mm (median 3mm). Testing speeds varied from 1.5-60mm/minute. Upon histology, the most commonly assessed structural and cellular factors were neovascularization and macrophages, respectively (n=9 each). Structural analysis was mostly qualitative, where cellular analysis was equally likely to be quantitative. 11 studies assessed adhesion formation, of which 8 used one of four scoring systems. 8 studies measured mesh shrinkage. Discussion: In vivo studies assessing mesh for HH and DH repair are uncommon. Within this relatively young field, we encourage surgical and materials testing institutions to discuss its standardisation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hiatus" title="hiatus">hiatus</a>, <a href="https://publications.waset.org/abstracts/search?q=diaphragmatic" title=" diaphragmatic"> diaphragmatic</a>, <a href="https://publications.waset.org/abstracts/search?q=hernia" title=" hernia"> hernia</a>, <a href="https://publications.waset.org/abstracts/search?q=mesh" title=" mesh"> mesh</a>, <a href="https://publications.waset.org/abstracts/search?q=materials%20testing" title=" materials testing"> materials testing</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20vivo" title=" in vivo"> in vivo</a> </p> <a href="https://publications.waset.org/abstracts/141777/a-systematic-review-examining-the-experimental-methodology-behind-in-vivo-testing-of-hiatus-hernia-and-diaphragmatic-hernia-mesh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141777.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">214</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">454</span> Comparison of Meshing Stiffness of Altered Tooth Sum Spur Gear Tooth with Different Pressure Angles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20K.%20Sachidananda">H.

Based on dynamic model a C-program has been developed to compute mesh stiffness. By using this program position dependent mesh stiffness of spur gear tooth for various profile shifts have been computed for a fixed center distance and altering tooth-sum gearing (100 by ± 4%). It is found that the C-program using dynamic model is one of the rapid soft computing technique which helps in design of gears. The mesh tooth stiffness along the path of contact is studied for both 20° and 25° pressure angle gears at various profile shifts. Better tooth stiffness is noticed in case of negative alteration tooth-sum gears compared to standard and positive alteration tooth-sum gears. Also, in case of negative alteration tooth-sum gearing better mesh stiffness is noticed in 20° pressure angle when compared to 25°. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=altered%20tooth-sum%20gearing" title="altered tooth-sum gearing">altered tooth-sum gearing</a>, <a href="https://publications.waset.org/abstracts/search?q=bending%20fatigue" title=" bending fatigue"> bending fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=mesh%20stiffness" title=" mesh stiffness"> mesh stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=spur%20gear" title=" spur gear"> spur gear</a> </p> <a href="https://publications.waset.org/abstracts/42914/comparison-of-meshing-stiffness-of-altered-tooth-sum-spur-gear-tooth-with-different-pressure-angles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42914.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">325</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">453</span> Numerical Simulation of Lifeboat Launching Using Overset Meshing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alok%20Khaware">Alok Khaware</a>, <a href="https://publications.waset.org/abstracts/search?q=Vinay%20Kumar%20Gupta"> Vinay Kumar Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean%20Noel%20Pederzani"> Jean Noel Pederzani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lifeboat launching from marine vessel or offshore platform is one of the important areas of research in offshore applications. With the advancement of computational fluid dynamic simulation (CFD) technology to solve fluid induced motions coupled with Six Degree of Freedom (6DOF), rigid body dynamics solver, it is now possible to predict the motion of the lifeboat precisely in different challenging conditions. Traditionally dynamic remeshing approach is used to solve this kind of problems, but remeshing approach has some bottlenecks to control good quality mesh in transient moving mesh cases. In the present study, an overset method with higher-order interpolation is used to simulate a lifeboat launched from an offshore platform into calm water, and volume of fluid (VOF) method is used to track free surface. Overset mesh consists of a set of overlapping component meshes, which allows complex geometries to be meshed with lesser effort. Good quality mesh with local refinement is generated at the beginning of the simulation and stay unchanged throughout the simulation. Overset mesh accuracy depends on the precise interpolation technique; the present study includes a robust and accurate least square interpolation method and results obtained with overset mesh shows good agreement with experiment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title="computational fluid dynamics">computational fluid dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20surface%20flow" title=" free surface flow"> free surface flow</a>, <a href="https://publications.waset.org/abstracts/search?q=lifeboat%20launching" title=" lifeboat launching"> lifeboat launching</a>, <a href="https://publications.waset.org/abstracts/search?q=overset%20mesh" title=" overset mesh"> overset mesh</a>, <a href="https://publications.waset.org/abstracts/search?q=volume%20of%20fluid" title=" volume of fluid"> volume of fluid</a> </p> <a href="https://publications.waset.org/abstracts/76173/numerical-simulation-of-lifeboat-launching-using-overset-meshing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76173.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">277</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">452</span> An Interpolation Tool for Data Transfer in Two-Dimensional Ice Accretion Problems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marta%20Cordero-Gracia">Marta Cordero-Gracia</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariola%20Gomez"> Mariola Gomez</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Blesbois"> Olivier Blesbois</a>, <a href="https://publications.waset.org/abstracts/search?q=Marina%20Carrion"> Marina Carrion</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the difficulties in icing simulations is for extended periods of exposure, when very large ice shapes are created. As well as being large, they can have complex shapes, such as a double horn. For icing simulations, these configurations are currently computed in several steps. The icing step is stopped when the ice shapes become too large, at which point a new mesh has to be created to allow for further CFD and ice growth simulations to be performed. This can be very costly, and is a limiting factor in the simulations that can be performed. A way to avoid the costly human intervention in the re-meshing step of multistep icing computation is to use mesh deformation instead of re-meshing. The aim of the present work is to apply an interpolation method based on Radial Basis Functions (RBF) to transfer deformations from surface mesh to volume mesh. This deformation tool has been developed specifically for icing problems. It is able to deal with localized, sharp and large deformations, unlike the tools traditionally used for more smooth wing deformations. This tool will be presented along with validation on typical two-dimensional icing shapes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ice%20accretion" title="ice accretion">ice accretion</a>, <a href="https://publications.waset.org/abstracts/search?q=interpolation" title=" interpolation"> interpolation</a>, <a href="https://publications.waset.org/abstracts/search?q=mesh%20deformation" title=" mesh deformation"> mesh deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20basis%20functions" title=" radial basis functions"> radial basis functions</a> </p> <a href="https://publications.waset.org/abstracts/59130/an-interpolation-tool-for-data-transfer-in-two-dimensional-ice-accretion-problems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59130.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">313</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">451</span> Optimization of Copper-Water Negative Inclination Heat Pipe with Internal Composite Wick Structure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20Brandys">I.

In WMN, gateways connect to Internet using wireline links and supply Internet access services for users. We usually need multiple gateways, which takes time and costs a lot of money set up, due to the limited wireless channel bit rate. WMN is a highly developed technology that offers to end users a wireless broadband access. It offers a high degree of flexibility contrasted to conventional networks; however, this attribute comes at the expense of a more complex construction. Therefore, a challenge is the planning and optimization of WMNs. In this paper, we concentrate on this challenge using a genetic algorithm and simulated annealing. The genetic algorithm and simulated annealing enable searching for a low-cost WMN configuration with constraints and determine the number of used gateways. Experimental results proved that the performance of the genetic algorithm and simulated annealing in minimizing WMN network costs while satisfying quality of service. The proposed models are presented to significantly outperform the existing solutions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wireless%20mesh%20networks" title="wireless mesh networks">wireless mesh networks</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithms" title=" genetic algorithms"> genetic algorithms</a>, <a href="https://publications.waset.org/abstracts/search?q=simulated%20annealing" title=" simulated annealing"> simulated annealing</a>, <a href="https://publications.waset.org/abstracts/search?q=topology%20design" title=" topology design"> topology design</a> </p> <a href="https://publications.waset.org/abstracts/11103/solving-the-wireless-mesh-network-design-problem-using-genetic-algorithm-and-simulated-annealing-optimization-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11103.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">458</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">447</span> Data Quality as a Pillar of Data-Driven Organizations: Exploring the Benefits of Data Mesh</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marc%20Bachelet">Marc Bachelet</a>, <a href="https://publications.waset.org/abstracts/search?q=Abhijit%20Kumar%20Chatterjee"> Abhijit Kumar Chatterjee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Manuel%20Avila"> José Manuel Avila</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Data quality is a key component of any data-driven organization. Without data quality, organizations cannot effectively make data-driven decisions, which often leads to poor business performance. Therefore, it is important for an organization to ensure that the data they use is of high quality. This is where the concept of data mesh comes in. Data mesh is an organizational and architectural decentralized approach to data management that can help organizations improve the quality of data. The concept of data mesh was first introduced in 2020. Its purpose is to decentralize data ownership, making it easier for domain experts to manage the data. This can help organizations improve data quality by reducing the reliance on centralized data teams and allowing domain experts to take charge of their data. This paper intends to discuss how a set of elements, including data mesh, are tools capable of increasing data quality. One of the key benefits of data mesh is improved metadata management. In a traditional data architecture, metadata management is typically centralized, which can lead to data silos and poor data quality. With data mesh, metadata is managed in a decentralized manner, ensuring accurate and up-to-date metadata, thereby improving data quality. Another benefit of data mesh is the clarification of roles and responsibilities. In a traditional data architecture, data teams are responsible for managing all aspects of data, which can lead to confusion and ambiguity in responsibilities. With data mesh, domain experts are responsible for managing their own data, which can help provide clarity in roles and responsibilities and improve data quality. Additionally, data mesh can also contribute to a new form of organization that is more agile and adaptable. By decentralizing data ownership, organizations can respond more quickly to changes in their business environment, which in turn can help improve overall performance by allowing better insights into business as an effect of better reports and visualization tools. Monitoring and analytics are also important aspects of data quality. With data mesh, monitoring, and analytics are decentralized, allowing domain experts to monitor and analyze their own data. This will help in identifying and addressing data quality problems in quick time, leading to improved data quality. Data culture is another major aspect of data quality. With data mesh, domain experts are encouraged to take ownership of their data, which can help create a data-driven culture within the organization. This can lead to improved data quality and better business outcomes. Finally, the paper explores the contribution of AI in the coming years. AI can help enhance data quality by automating many data-related tasks, like data cleaning and data validation. By integrating AI into data mesh, organizations can further enhance the quality of their data. The concepts mentioned above are illustrated by AEKIDEN experience feedback. AEKIDEN is an international data-driven consultancy that has successfully implemented a data mesh approach.

In order to take into account pintle movement, a sliding mesh method was applied. The chamber pressure, mass flow rate, and thrust have been analyzed, and the response lag and sensitivity at the chamber and nozzle were estimated for a movable pintle. The nozzle performance for pintle reciprocating as its insertion and extraction processes, were analyzed to better understand the dynamic performance of the pintle nozzle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pintle" title="pintle">pintle</a>, <a href="https://publications.waset.org/abstracts/search?q=sliding%20mesh" title=" sliding mesh"> sliding mesh</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulent%20model" title=" turbulent model"> turbulent model</a>, <a href="https://publications.waset.org/abstracts/search?q=compressibility%20correction" title=" compressibility correction"> compressibility correction</a> </p> <a href="https://publications.waset.org/abstracts/3296/a-sliding-mesh-technique-and-compressibility-correction-effects-of-two-equation-turbulence-models-for-a-pintle-perturbed-flow-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3296.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">489</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">445</span> Evaluating the Performance of Passive Direct Methanol Fuel Cell under Varying Operating and Structural Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rahul%20Saraswat">Rahul Saraswat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> More recently, a focus has been given to replacing machined stainless steel metal flow fields with inexpensive wire mesh current collectors. The flow fields are based on simple woven wire mesh screens of various stainless steels, which are sandwiched between a thin metal plate of the same material to create a bipolar plate/flow field configuration for use in a stack. Major advantages of using stainless steel wire screens include the elimination of expensive raw materials as well as machining and/or other special fabrication costs. The objective of the project is to improve the performance of the passive direct methanol fuel cell without increasing the cost of the cell and to make it as compact and light as possible. From the literature survey, it was found that very little is done in this direction, and the following methodology was used. 1. The passive direct methanol fuel cell (DMFC) can be made more compact, lighter, and less costly by changing the material used in its construction. 2. Controlling the fuel diffusion rate through the cell improves the performance of the cell. A passive liquid feed direct methanol fuel cell (DMFC) was fabricated using a given MEA (Membrane Electrode Assembly) and tested for different current collector structures. Mesh current collectors of different mesh densities along with different support structures, were used, and the performance was found to be better. Methanol concentration was also varied. Optimisation of mesh size, support structure, and fuel concentration was achieved. Cost analysis was also performed hereby. From the performance analysis study of DMFC, we can conclude with the following points: Area specific resistance (ASR) of wire mesh current collectors is lower than the ASR of stainless steel current collectors. Also, the power produced by wire mesh current collectors is always more than that produced by stainless steel current collectors. 1. Low or moderate methanol concentrations should be used for better and stable DMFC performance. 2. Wiremesh is a good substitute for stainless steel for current collector plates of passive DMFC because of its lower cost (by about 27 %), flexibility, and light in weight characteristics of wire mesh.
