The next step is to enable these tools to be used within a portal framework. The portal framework consists of pages having several small windows that contain individual data warehouse query results. There are several issues that need to be considered when designing the architecture for a portal enabled data warehouse query tool. Some issues need special techniques that can overcome the limitations that are imposed by the nature of data warehouse queries. Issues such as single sign-on, query result caching and sharing, customization, scheduling and authorization need to be considered. This paper discusses such issues and suggests an architecture to support data warehouse queries within Web portal frameworks.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Data%20Warehousing%20tools" title="Data Warehousing tools">Data Warehousing tools</a>, <a href="https://publications.waset.org/search?q=data%20warehousing%20queries" title=" data warehousing queries"> data warehousing queries</a>, <a href="https://publications.waset.org/search?q=web%20portal%20frameworks." title=" web portal frameworks."> web portal frameworks.</a> </p> <a href="https://publications.waset.org/10540/issues-and-architecture-for-supporting-data-warehouse-queries-in-web-portals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10540/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10540/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10540/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10540/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10540/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10540/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10540/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10540/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10540/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10540/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10540.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">2121</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">292</span> A Study on the Location and Range of Obstacle Region in Robot's Point Placement Task based on the Vision Control Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Jae%20Kyung%20Son">Jae Kyung Son</a>, <a href="https://publications.waset.org/search?q=Wan%20Shik%20Jang"> Wan Shik Jang</a>, <a href="https://publications.waset.org/search?q=Sung%20hyun%20Shim"> Sung hyun Shim</a>, <a href="https://publications.waset.org/search?q=Yoon%20Gyung%20Sung"> Yoon Gyung Sung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>This paper is concerned with the application of the vision control algorithm for robot's point placement task in discontinuous trajectory caused by obstacle. The presented vision control algorithm consists of four models, which are the robot kinematic model, vision system model, parameters estimation model, and robot joint angle estimation model.When the robot moves toward a target along discontinuous trajectory, several types of obstacles appear in two obstacle regions. Then, this study is to investigate how these changes will affect the presented vision control algorithm.Thus, the practicality of the vision control algorithm is demonstrated experimentally by performing the robot's point placement task in discontinuous trajectory by obstacle.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Vision%20control%20algorithm" title="Vision control algorithm">Vision control algorithm</a>, <a href="https://publications.waset.org/search?q=location%20of%20obstacle%20region" title=" location of obstacle region"> location of obstacle region</a>, <a href="https://publications.waset.org/search?q=range%20of%20obstacle%20region" title=" range of obstacle region"> range of obstacle region</a>, <a href="https://publications.waset.org/search?q=point%20placement." title=" point placement."> point placement.</a> </p> <a href="https://publications.waset.org/9750/a-study-on-the-location-and-range-of-obstacle-region-in-robots-point-placement-task-based-on-the-vision-control-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9750/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9750/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9750/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9750/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9750/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9750/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9750/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9750/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9750/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9750/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9750.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">1402</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">291</span> A Study on the Comparison of Mechanical and Thermal Properties According to Laminated Orientation of CFRP through Bending Test</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Hee%20Jae%20Shin">Hee Jae Shin</a>, <a href="https://publications.waset.org/search?q=Lee%20Ku%20Kwac"> Lee Ku Kwac</a>, <a href="https://publications.waset.org/search?q=In%20Pyo%20Cha"> In Pyo Cha</a>, <a href="https://publications.waset.org/search?q=Min%20Sang%20Lee"> Min Sang Lee</a>, <a href="https://publications.waset.org/search?q=Hyun%20Kyung%20Yoon"> Hyun Kyung Yoon</a>, <a href="https://publications.waset.org/search?q=Hong%20Gun%20Kim"> Hong Gun Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>In rapid industrial development, the demand for high-strength and lightweight materials have been increased. Thus, various CFRP (Carbon Fiber Reinforced Plastics) with composite materials are being used. The design variables of CFRP are its lamination direction, order and thickness. Thus, the hardness and strength of CFRP depends much on their design variables. In this paper, the lamination direction of CFRP was used to produce a symmetrical ply [0°/0°, -15°/+15°, -30°/+30°, -45°/+45°, -60°/+60°, -75°/+75° and 90°/90°] and an asymmetrical ply [0°/15°, 0°/30°, 0°/45°, 0°/60° 0°/75° and 0°/90°]. The bending flexure stress of the CFRP specimen was evaluated through a bending test. Its thermal property was measured using an infrared camera. The symmetrical specimen and the asymmetrical specimen were analyzed. The results showed that the asymmetrical specimen increased the bending loads according to the increase in the orientation angle; and from 0°, the symmetrical specimen showed a tendency opposite the asymmetrical tendency because the tensile force of fiber differs at the vertical direction of its load. Also, the infrared camera showed that the thermal property had a trend similar to that of the mechanical properties.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Carbon%20Fiber%20Reinforced%20Plastic%20%28CFRP%29" title="Carbon Fiber Reinforced Plastic (CFRP)">Carbon Fiber Reinforced Plastic (CFRP)</a>, <a href="https://publications.waset.org/search?q=Bending%0D%0ATest" title=" Bending Test"> Bending Test</a>, <a href="https://publications.waset.org/search?q=Infrared%20Camera" title=" Infrared Camera"> Infrared Camera</a>, <a href="https://publications.waset.org/search?q=Composite." title=" Composite."> Composite.</a> </p> <a href="https://publications.waset.org/10000684/a-study-on-the-comparison-of-mechanical-and-thermal-properties-according-to-laminated-orientation-of-cfrp-through-bending-test" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10000684/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10000684/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10000684/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10000684/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10000684/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10000684/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10000684/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10000684/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10000684/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10000684/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10000684.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">2029</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">290</span> Electromagnetic Interference Shielding Characteristics for Stainless Wire Mesh and Number of Plies of Carbon Fiber Reinforced Plastic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Min%20Sang%20Lee">Min Sang Lee</a>, <a href="https://publications.waset.org/search?q=Hee%20Jae%20Shin"> Hee Jae Shin</a>, <a href="https://publications.waset.org/search?q=In%20Pyo%20Cha"> In Pyo Cha</a>, <a href="https://publications.waset.org/search?q=Hyun%20Kyung%20Yoon"> Hyun Kyung Yoon</a>, <a href="https://publications.waset.org/search?q=Seong%20Woo%20Hong"> Seong Woo Hong</a>, <a href="https://publications.waset.org/search?q=Min%20Jae%20Yu"> Min Jae Yu</a>, <a href="https://publications.waset.org/search?q=Hong%20Gun%20Kim"> Hong Gun Kim</a>, <a href="https://publications.waset.org/search?q=Lee%20Ku%20Kwac"> Lee Ku Kwac</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>In this paper, the electromagnetic shielding characteristics of an up-to-date typical carbon filler material, carbon fiber used with a metal mesh were investigated.

By grafting carbon fibers, on which studies are being actively underway in the environmental aspects and electromagnetic shielding effect, with hybrid-type wire meshes that were analysed through the tests, in this study, the applicability and possibility are proposed.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Carbon%20Fiber%20Reinforced%20Plastic%20%28CFRP%29" title="Carbon Fiber Reinforced Plastic (CFRP)">Carbon Fiber Reinforced Plastic (CFRP)</a>, <a href="https://publications.waset.org/search?q=Glass%20Fiber%0D%0AReinforced%20Plastic%20%28GFRP%29" title=" Glass Fiber Reinforced Plastic (GFRP)"> Glass Fiber Reinforced Plastic (GFRP)</a>, <a href="https://publications.waset.org/search?q=Stainless%20Wire%20Mesh" title=" Stainless Wire Mesh"> Stainless Wire Mesh</a>, <a href="https://publications.waset.org/search?q=Electromagnetic%0D%0AShielding." title=" Electromagnetic Shielding."> Electromagnetic Shielding.</a> </p> <a href="https://publications.waset.org/10000484/electromagnetic-interference-shielding-characteristics-for-stainless-wire-mesh-and-number-of-plies-of-carbon-fiber-reinforced-plastic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10000484/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10000484/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10000484/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10000484/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10000484/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10000484/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10000484/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10000484/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10000484/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10000484/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10000484.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">2752</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">289</span> A Study on the Interlaminar Shear Strength of Carbon Fiber Reinforced Plastics Depending on the Lamination Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Min%20Sang%20Lee">Min Sang Lee</a>, <a href="https://publications.waset.org/search?q=Hee%20Jae%20Shin"> Hee Jae Shin</a>, <a href="https://publications.waset.org/search?q=In%20Pyo%20Cha"> In Pyo Cha</a>, <a href="https://publications.waset.org/search?q=Sun%20Ho%20Ko"> Sun Ho Ko</a>, <a href="https://publications.waset.org/search?q=Hyun%20Kyung%20Yoon"> Hyun Kyung Yoon</a>, <a href="https://publications.waset.org/search?q=Hong%20Gun%20Kim"> Hong Gun Kim</a>, <a href="https://publications.waset.org/search?q=Lee%20Ku%20Kwac"> Lee Ku Kwac</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>The prepreg process among the CFRP (Carbon Fiber Reinforced Plastic) forming methods is the short term of ‘Pre-impregnation’, which is widely used for aerospace composites that require a high quality property such as a fiber-reinforced woven fabric, in which an epoxy hardening resin is impregnated the reality. However, that this process requires continuous researches and developments for its commercialization because the delamination characteristically develops between the layers when a great weight is loaded from outside to supplement such demerit, three lamination methods among the prepreg lamination methods of CFRP were designed to minimize the delamination between the layers due to external impacts. Further, the newly designed methods and the existing lamination methods were analyzed through a mechanical characteristic test, Interlaminar Shear Strength test. The Interlaminar Shear Strength test result confirmed that the newly proposed three lamination methods, i.e. the Roll, Half and Zigzag laminations, presented more excellent strengths compared to the conventional Ply lamination. The interlaminar shear strength in the roll method with relatively dense fiber distribution was approximately 1.75% higher than that in the existing ply lamination method, and in the half method, it was approximately 0.78% higher.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Carbon%20Fiber%20Reinforced%20Plastic%20%28CFRP%29" title="Carbon Fiber Reinforced Plastic (CFRP)">Carbon Fiber Reinforced Plastic (CFRP)</a>, <a href="https://publications.waset.org/search?q=Pre-Impregnation" title=" Pre-Impregnation"> Pre-Impregnation</a>, <a href="https://publications.waset.org/search?q=Laminating%20Method" title=" Laminating Method"> Laminating Method</a>, <a href="https://publications.waset.org/search?q=Interlaminar%20Shear%20Strength%0D%0A%28ILSS%29." title=" Interlaminar Shear Strength (ILSS)."> Interlaminar Shear Strength (ILSS).</a> </p> <a href="https://publications.waset.org/10000485/a-study-on-the-interlaminar-shear-strength-of-carbon-fiber-reinforced-plastics-depending-on-the-lamination-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10000485/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10000485/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10000485/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10000485/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10000485/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10000485/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10000485/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10000485/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10000485/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10000485/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10000485.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">2910</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">288</span> Intuitive Robot Control Using Surface EMG and Accelerometer Signals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Kiwon%20Rhee">Kiwon Rhee</a>, <a href="https://publications.waset.org/search?q=Kyung-Jin%20You"> Kyung-Jin You</a>, <a href="https://publications.waset.org/search?q=Hyun-Chool%20Shin"> Hyun-Chool Shin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>This paper proposes a method of remotely controlling robots with arm gestures using surface electromyography (EMG) and accelerometer sensors attached to the operator’s wrists.

It is much more complex, usually large in size, and continuously changes. Until recently business data has been the main target for discovering trends, patterns or future expectations. However, with the recent rise in biotechnology, the powerful technology that was used for analyzing business data is now being applied to biological data. With the advanced technology at hand, the main trend in biological research is rapidly changing from structural DNA analysis to understanding cellular functions of the DNA sequences. DNA chips are now being used to perform experiments and DNA analysis processes are being used by researchers. Clustering is one of the important processes used for grouping together similar entities. There are many clustering algorithms such as hierarchical clustering, self-organizing maps, K-means clustering and so on. In this paper, we propose a clustering algorithm that imitates the ecosystem taking into account the features of biological data. We implemented the system using an Ant-Colony clustering algorithm. The system decides the number of clusters automatically. The system processes the input biological data, runs the Ant-Colony algorithm, draws the Topic Map, assigns clusters to the genes and displays the output. We tested the algorithm with a test data of 100 to1000 genes and 24 samples and show promising results for applying this algorithm to clustering DNA chip data.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Ant%20colony%20system" title="Ant colony system">Ant colony system</a>, <a href="https://publications.waset.org/search?q=biological%20data" title=" biological data"> biological data</a>, <a href="https://publications.waset.org/search?q=clustering" title=" clustering"> clustering</a>, <a href="https://publications.waset.org/search?q=DNA%20chip." title=" DNA chip."> DNA chip.</a> </p> <a href="https://publications.waset.org/7932/an-ant-based-clustering-system-for-knowledge-discovery-in-dna-chip-analysis-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/7932/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/7932/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/7932/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/7932/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/7932/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/7932/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/7932/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/7932/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/7932/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/7932/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/7932.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">1974</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">286</span> Two Undetectable On-line Dictionary Attacks on Debiao et al.鈥檚 S-3PAKE Protocol</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Sung-Bae%20Choi">Sung-Bae Choi</a>, <a href="https://publications.waset.org/search?q=Sang-Yoon%20Yoon"> Sang-Yoon Yoon</a>, <a href="https://publications.waset.org/search?q=Eun-Jun%20Yoon"> Eun-Jun Yoon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>In 2011, Debiao et al. pointed out that S-3PAKE protocol proposed by Lu and Cao for password-authenticated key exchange in the three-party setting is vulnerable to an off-line dictionary attack.

In this study, primary coolant flow coastdown phenomena are investigated for the Jordan Research and Training Reactor (JRTR) using a simulation software package, Modular Modeling System (MMS). Two MMS models are built. The first one is a simple model to investigate the characteristics of the primary coolant pump only. The second one is a model for a simulation of the Primary Coolant System (PCS) loop, in which all the detailed design data of the JRTR PCS system are modeled, including the geometrical arrangement data. The same design data for a PCS pump are used for both models. Coastdown curves obtained from the two models are compared to study the PCS loop coolant inertia effect on a flow coastdown. Results showed that the loop coolant inertia effect is found to be small in the JRTR PCS loop, i.e., about one second increases in a coastdown half time required to halve the coolant flow rate. The effects of different flywheel inertia on the flow coastdown are also investigated. It is demonstrated that the coastdown half time increases with the flywheel inertia linearly. The designed coastdown half time is proved to be well above the design requirement for the fuel integrity.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Flow%20Coastdown" title="Flow Coastdown">Flow Coastdown</a>, <a href="https://publications.waset.org/search?q=Loop%20Coolant%20Inertia" title=" Loop Coolant Inertia"> Loop Coolant Inertia</a>, <a href="https://publications.waset.org/search?q=Modeling" title=" Modeling"> Modeling</a>, <a href="https://publications.waset.org/search?q=Research%20Reactor." title=" Research Reactor."> Research Reactor.</a> </p> <a href="https://publications.waset.org/9997924/analyses-for-primary-coolant-pump-coastdown-phenomena-for-jordan-research-and-training-reactor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9997924/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9997924/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9997924/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9997924/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9997924/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9997924/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9997924/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9997924/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9997924/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9997924/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9997924.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">3796</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">283</span> Analytical Approach of the In-Pipe Robot on Branched Pipe Navigation and Its Solution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Yoon%20Koo%20Kang">Yoon Koo Kang</a>, <a href="https://publications.waset.org/search?q=Jung%20wan%20Park"> Jung wan Park</a>, <a href="https://publications.waset.org/search?q=Hyun%20Seok%20Yang"> Hyun Seok Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper determines most common model of in-pipe robots to derive its degree of freedom in order to compare with the necessary degree of freedom required for a system to move inside pipelines freely in order to derive analytical reason for losing control of in-pipe robots at branched pipe.

Communication between the main CPU and the PCP is executed via a common area of RAM and events on either processor which are invoked by interrupts. Safety-related software is also implemented to provide a reliable, self-testing computing environment for safety critical and high integrity applications.

The purpose of this study was to identify the relative importance factors to improve performance of the of judo athletes with visual impairments, including blindness by using the Analytic Hierarchy Process (AHP). After reviewing the literature, the relative importance of factors affecting performance of the blind judo was selected. A group of expert reviewed the first draft of the questionnaires, and then finally selected performance factors were classified into the major categories of techniques, physical fitness, and psychological categories. Later, a pre-selected experts group was asked to review the final version of questionnaire and confirm the priories of performance factors. The order of priority was determined by performing pairwise comparisons using Expert Choice 2000. Results indicated that “grappling” (.303) and “throwing” (.234) were the most important lower hierarchy factors for blind judo skills. In addition, the most important physical factors affecting performance were “muscular strength and endurance” (.238). Further, among other psychological factors “competitive anxiety” (.393) was important factor that affects performance. It is important to offer psychological skills training to reduce anxiety of judo athletes with visual impairments and blindness, so they can compete in their optimal states. These findings offer insights into what should be considered when determining factors to improve performance of judo athletes with visual impairments and blindness.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Analytic%20hierarchy%20process" title="Analytic hierarchy process">Analytic hierarchy process</a>, <a href="https://publications.waset.org/search?q=blind%20athlete" title=" blind athlete"> blind athlete</a>, <a href="https://publications.waset.org/search?q=judo" title=" judo"> judo</a>, <a href="https://publications.waset.org/search?q=sport%20performance." title=" sport performance.

The method deals with the problem of robot in driving from an initial position to a target position based on elastic force and potential field force. To avoid the obstacles, the robot has to modify the trajectory based on signal received from the sensor system in the sampling times. It was evident that with the combination of Modification Elastic strip and Pseudomedian filter to process the nonlinear data from sensor uncertainties in the data received from the sensor system can be reduced.

It possesses strong antioxidant and antiinflammatory properties. In the present study, the anti-inflammatory effects of F. deltoidea extract on UVB-irradiated HaCaT Keratinocytes were investigated. HaCaT Keratinocytes were UVBirradiated (12.5 mJ/cm3) and were treated with 0.05, 0.08 or 0.1% of F. deltoidea extract. Cell viability following UVB irradiation was significantly higher in the groups treated with the F. deltoidea extract at doses of 0.05, 0.08 or 0.1% than in control group with UVB irradiation only. Tumor necrosis factor-α (TNF-α), interleukin-1α (IL-1α), interleukin-6 (IL-6) and cyclooxygenase (COX-2) play primary roles in the inflammation process upon UV irradiation and are known to be stimulated by UVB irradiation. Treatment with the F. deltoidea extract dramatically inhibited the UV-induced TNF-α, IL-1α, IL-6, and COX-2 expression.

More overlaps can offer higher data throughput; however, they may cause more intersymbol interference (ISI) at the same time, resulting in serious bit error rate (BER) performance degradation. In this paper, we perform the BER analysis and derive a closed form BER expression for the overlap-based CSS system. The derived BER expression includes the number of overlaps as a parameter, and thus, would be very useful in determining the number of overlaps for a specified BER. The numerical results demonstrate that the BER derived in a closed form closely agrees with the simulated BER. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=CSS" title="CSS">CSS</a>, <a href="https://publications.waset.org/search?q=DM" title=" DM"> DM</a>, <a href="https://publications.waset.org/search?q=chirp" title=" chirp"> chirp</a>, <a href="https://publications.waset.org/search?q=overlap." title=" overlap."> overlap.</a> </p> <a href="https://publications.waset.org/12055/bit-error-rate-performance-analysis-of-an-overlap-based-css-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/12055/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/12055/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/12055/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/12055/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/12055/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/12055/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/12055/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/12055/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/12055/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/12055/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/12055.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">2100</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">277</span> Analysis of Impact of Land Use Regulations against Urban Spatial Structure - Centering around Shiheung City</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Chang-il%20Kang">Chang-il Kang</a>, <a href="https://publications.waset.org/search?q=Yoon-Hong%20Park"> Yoon-Hong Park</a>, <a href="https://publications.waset.org/search?q=Tae-Hyun%20Kim"> Tae-Hyun Kim</a>, <a href="https://publications.waset.org/search?q=Yu%20Wann"> Yu Wann</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>In this paper, we analyzed the pattern of urban spatial structure of Siheung City that had been divided into two parts and presented alternative plans in order to get rid of these phenomena.

However, the heat and radiation in the nuclear power plant causes the rapid performance deterioration of cables in nuclear vessels and heat exchangers, which requires cable lifetime estimation. The most accurate method of estimating the cable lifetime is to evaluate the cables in a laboratory. However, removing cables while the plant is operating is not allowed because of its safety and cost. In this paper, a robot system to estimate the cable lifetime in nuclear power plants is developed and tested. The developed robot system can calculate a modulus value to estimate the cable lifetime even when the nuclear power plant is in operation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Autonomous%20robot" title="Autonomous robot">Autonomous robot</a>, <a href="https://publications.waset.org/search?q=Cable%20Inspection" title=" Cable Inspection"> Cable Inspection</a>, <a href="https://publications.waset.org/search?q=Indenter" title=" Indenter"> Indenter</a>, <a href="https://publications.waset.org/search?q=Nuclear%20Power%20Plant" title="Nuclear Power Plant">Nuclear Power Plant</a> </p> <a href="https://publications.waset.org/13377/development-of-autonomous-cable-inspection-robot-for-nuclear-power-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/13377/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/13377/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/13377/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/13377/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/13377/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/13377/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/13377/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/13377/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/13377/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/13377/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/13377.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">2013</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">275</span> A Two-Step Approach for Tree-structured XPath Query Reduction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Minsoo%20Lee">Minsoo Lee</a>, <a href="https://publications.waset.org/search?q=Yun-mi%20Kim"> Yun-mi Kim</a>, <a href="https://publications.waset.org/search?q=Yoon-kyung%20Lee"> Yoon-kyung Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> XML data consists of a very flexible tree-structure which makes it difficult to support the storing and retrieving of XML data. The node numbering scheme is one of the most popular approaches to store XML in relational databases. Together with the node numbering storage scheme, structural joins can be used to efficiently process the hierarchical relationships in XML. However, in order to process a tree-structured XPath query containing several hierarchical relationships and conditional sentences on XML data, many structural joins need to be carried out, which results in a high query execution cost. This paper introduces mechanisms to reduce the XPath queries including branch nodes into a much more efficient form with less numbers of structural joins. A two step approach is proposed. The first step merges duplicate nodes in the tree-structured query and the second step divides the query into sub-queries, shortens the paths and then merges the sub-queries back together. The proposed approach can highly contribute to the efficient execution of XML queries. Experimental results show that the proposed scheme can reduce the query execution cost by up to an order of magnitude of the original execution cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=XML" title="XML">XML</a>, <a href="https://publications.waset.org/search?q=Xpath" title=" Xpath"> Xpath</a>, <a href="https://publications.waset.org/search?q=tree-structured%20query" title=" tree-structured query"> tree-structured query</a>, <a href="https://publications.waset.org/search?q=query%20reduction." title=" query reduction."> query reduction.</a> </p> <a href="https://publications.waset.org/12893/a-two-step-approach-for-tree-structured-xpath-query-reduction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/12893/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/12893/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/12893/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/12893/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/12893/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/12893/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/12893/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/12893/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/12893/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/12893/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/12893.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">1549</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">274</span> A Simulation for Estimation of the Blood Pressure using Arterial Pressure-volume Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Gye-rok%20Jeon">Gye-rok Jeon</a>, <a href="https://publications.waset.org/search?q=Jae-hee%20Jung"> Jae-hee Jung</a>, <a href="https://publications.waset.org/search?q=In-cheol%20Kim"> In-cheol Kim</a>, <a href="https://publications.waset.org/search?q=Ah-young%20Jeon"> Ah-young Jeon</a>, <a href="https://publications.waset.org/search?q=Sang-hwa%20Yoon"> Sang-hwa Yoon</a>, <a href="https://publications.waset.org/search?q=Jung-man%20Son"> Jung-man Son</a>, <a href="https://publications.waset.org/search?q=Jae-hyung%20Kim"> Jae-hyung Kim</a>, <a href="https://publications.waset.org/search?q=Soo-young%20Ye"> Soo-young Ye</a>, <a href="https://publications.waset.org/search?q=Jung-hoon%20Ro"> Jung-hoon Ro</a>, <a href="https://publications.waset.org/search?q=Dong-hyun%20Kim"> Dong-hyun Kim</a>, <a href="https://publications.waset.org/search?q=Chul-han%20Kim"> Chul-han Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A analysis on the conventional the blood pressure estimation method using an oscillometric sphygmomanometer was performed through a computer simulation using an arterial pressure-volume (APV) model. Traditionally, the maximum amplitude algorithm (MAP) was applied on the oscillation waveforms of the APV model to obtain the mean arterial pressure and the characteristic ratio. The estimation of mean arterial pressure and characteristic ratio was significantly affected with the shape of the blood pressure waveforms and the cutoff frequency of high-pass filter (HPL) circuitry. Experimental errors are due to these effects when estimating blood pressure. To find out an algorithm independent from the influence of waveform shapes and parameters of HPL, the volume oscillation of the APV model and the phase shift of the oscillation with fast fourier transform (FFT) were testified while increasing the cuff pressure from 1 mmHg to 200 mmHg (1 mmHg per second). The phase shift between the ranges of volume oscillation was then only observed between the systolic and the diastolic blood pressures. The same results were also obtained from the simulations performed on two different the arterial blood pressure waveforms and one hyperthermia waveform. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Arterial%20blood%20pressure" title="Arterial blood pressure">Arterial blood pressure</a>, <a href="https://publications.waset.org/search?q=oscillometric%20method" title=" oscillometric method"> oscillometric method</a> </p> <a href="https://publications.waset.org/10956/a-simulation-for-estimation-of-the-blood-pressure-using-arterial-pressure-volume-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10956/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10956/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10956/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10956/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10956/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10956/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10956/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10956/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10956/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10956/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10956.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">3337</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">273</span> A Novel Estimation Method for Integer Frequency Offset in Wireless OFDM Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Taeung%20Yoon">Taeung Yoon</a>, <a href="https://publications.waset.org/search?q=Youngpo%20Lee"> Youngpo Lee</a>, <a href="https://publications.waset.org/search?q=Chonghan%20Song"> Chonghan Song</a>, <a href="https://publications.waset.org/search?q=Na%20Young%20Ha"> Na Young Ha</a>, <a href="https://publications.waset.org/search?q=Seokho%20Yoon"> Seokho Yoon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ren et al. presented an efficient carrier frequency offset (CFO) estimation method for orthogonal frequency division multiplexing (OFDM), which has an estimation range as large as the bandwidth of the OFDM signal and achieves high accuracy without any constraint on the structure of the training sequence. However, its detection probability of the integer frequency offset (IFO) rapidly varies according to the fractional frequency offset (FFO) change. In this paper, we first analyze the Ren-s method and define two criteria suitable for detection of IFO. Then, we propose a novel method for the IFO estimation based on the maximum-likelihood (ML) principle and the detection criteria defined in this paper.

RC walls are subjected to axial forces in common and the effect of axial forces on the strength loss of the fire damaged walls has not been investigated. This paper aims at investigating temperature distribution on fire damaged concrete walls having different axial loads. In the experiments, a variable of specimens is axial force ratio. RC walls are fabricated with 150mm of wall thicknesses, 750mm of lengths and 1,300mm of heights having concrete strength of 24MPa. After curing, specimens are heated on one surface with ISO-834 standard time-temperature curve for 2 hours and temperature distributions during the test are measured using thermocouples inside the walls. The experimental results show that the temperature of the RC walls exposed to fire increases as axial force ratio increases. To verify the experiments, finite element (FE) models are generated for coupled temperature-structure analyses. The analytical results of thermal behaviors are in good agreement with the experimental results. The predicted displacement of the walls decreases when the axial force increases. </p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Axial%20force%20ratio" title="Axial force ratio">Axial force ratio</a>, <a href="https://publications.waset.org/search?q=coupled%20analysis" title=" coupled analysis"> coupled analysis</a>, <a href="https://publications.waset.org/search?q=fire" title=" fire"> fire</a>, <a href="https://publications.waset.org/search?q=reinforced%20concrete%20wall" title=" reinforced concrete wall"> reinforced concrete wall</a>, <a href="https://publications.waset.org/search?q=temperature%20distribution." title=" temperature distribution."> temperature distribution.</a> </p> <a href="https://publications.waset.org/10003566/investigation-of-fire-damaged-reinforced-concrete-walls-with-axial-force" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10003566/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10003566/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10003566/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10003566/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10003566/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10003566/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10003566/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10003566/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10003566/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10003566/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10003566.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">1739</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">270</span> Comparative Study of View Point Types on Landscape Evaluation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Yoon%20Jung%20Sik">Yoon Jung Sik</a>, <a href="https://publications.waset.org/search?q=Bur-Deul%20Yoon"> Bur-Deul Yoon</a>, <a href="https://publications.waset.org/search?q=Ki%20Hun%20Kim"> Ki Hun Kim</a>, <a href="https://publications.waset.org/search?q=Chang%20Hoon"> Chang Hoon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>The purpose of this study was to examine the viewpoints in terms of changing distances and levels and thereby, comparatively analyze the visual sensitivity to the elements of the natural views.

Pilot controlled proportional valve is designed and analyzed to get small pressure change rate after blow-off, and to get a fast response of the damper, a reverse damping mechanism is adapted. The reverse continuous variable damper is designed as a HS-SH damper which offers good body control with reduced transferred input force from the tire, compared with any other type of suspension system. The damper structure is designed, so that rebound and compression damping forces can be tuned independently, of which the variable valve is placed externally. The rate of pressure change with respect to the flow rate after blow-off becomes smooth when the fixed orifice size increases, which means that the blow-off slope is controllable using the fixed orifice size. Damping forces are measured with the change of the solenoid current at the different piston velocities to confirm the maximum hysteresis of 20 N, linearity, and variance of damping force. The damping force variance is wide and continuous, and is controlled by the spool opening, of which scheme is usually adapted in proportional valves. The reverse continuous variable damper developed in this study is expected to be utilized in the semi-active suspension systems in passenger cars after its performance and simplicity of the design is confirmed through a real car test. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Blow-off" title="Blow-off">Blow-off</a>, <a href="https://publications.waset.org/search?q=damping%20force" title=" damping force"> damping force</a>, <a href="https://publications.waset.org/search?q=pilot%20controlledproportional%20valve" title=" pilot controlledproportional valve"> pilot controlledproportional valve</a>, <a href="https://publications.waset.org/search?q=reverse%20continuous%20damper." title=" reverse continuous damper."> reverse continuous damper.</a> </p> <a href="https://publications.waset.org/12086/a-study-on-the-performance-characteristics-of-variable-valve-for-reverse-continuous-damper" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/12086/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/12086/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/12086/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/12086/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/12086/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/12086/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/12086/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/12086/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/12086/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/12086/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/12086.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">2440</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">268</span> Automotive ECU Design with Functional Safety for Electro-Mechanical Actuator Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Kyung-Jung%20Lee">Kyung-Jung Lee</a>, <a href="https://publications.waset.org/search?q=Young-Hun%20Ki"> Young-Hun Ki</a>, <a href="https://publications.waset.org/search?q=Hyun-Sik%20Ahn"> Hyun-Sik Ahn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>In this paper, we propose a hardware and software design method for automotive Electronic Control Units (ECU) considering the functional safety. The proposed ECU is considered for the application to Electro-Mechanical Actuator systems and the validity of the design method is shown by the application to the Electro-Mechanical Brake (EMB) control system which is used as a brake actuator in Brake-By-Wire (BBW) systems. The importance of a functional safety-based design approach to EMB ECU design has been emphasized because of its safety-critical functions, which are executed with the aid of many electric actuators, sensors, and application software. Based on hazard analysis and risk assessment according to ISO26262, the EMB system should be ASIL-D-compliant, the highest ASIL level. To this end, an external signature watchdog and an Infineon 32-bit microcontroller TriCore are used to reduce risks considering common-cause hardware failure. Moreover, a software design method is introduced for implementing functional safety-oriented monitoring functions based on an asymmetric dual core architecture considering redundancy and diversity. The validity of the proposed ECU design approach is verified by using the EMB Hardware-In-the-Loop (HILS) system, which consists of the EMB assembly, actuator ECU, a host PC, and a few debugging devices. Furthermore, it is shown that the existing sensor fault tolerant control system can be used more effectively for mitigating the effects of hardware and software faults by applying the proposed ECU design method.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=BBW%20%28Brake-By-wire%29" title="BBW (Brake-By-wire)">BBW (Brake-By-wire)</a>, <a href="https://publications.waset.org/search?q=EMB%20%28Electro-Mechanical%0D%0ABrake%29" title=" EMB (Electro-Mechanical Brake)"> EMB (Electro-Mechanical Brake)</a>, <a href="https://publications.waset.org/search?q=Functional%20Safety" title=" Functional Safety"> Functional Safety</a>, <a href="https://publications.waset.org/search?q=ISO26262." title=" ISO26262."> ISO26262.</a> </p> <a href="https://publications.waset.org/16464/automotive-ecu-design-with-functional-safety-for-electro-mechanical-actuator-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/16464/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/16464/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/16464/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/16464/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/16464/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/16464/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/16464/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/16464/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/16464/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/16464/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/16464.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">6996</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">267</span> Secondary School Students- Perceptions about Biological Issues in South Korea</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Jung-Hyun%20Kim">Jung-Hyun Kim</a>, <a href="https://publications.waset.org/search?q=Kew-Cheol%20Shim"> Kew-Cheol Shim</a>, <a href="https://publications.waset.org/search?q=Shin-Cheol%20Song"> Shin-Cheol Song</a>, <a href="https://publications.waset.org/search?q=Kyoungho%20Kim"> Kyoungho Kim</a>, <a href="https://publications.waset.org/search?q=Nam-Il%20Kim"> Nam-Il Kim</a>, <a href="https://publications.waset.org/search?q=Jinho%20Bae"> Jinho Bae</a>, <a href="https://publications.waset.org/search?q=Keum-Hyun%20So"> Keum-Hyun So</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of present paper was to investigate perceptions of Korean secondary school students about social issues related to biological sciences.

The Platform Screen Doors (PSDs) can improve indoor air quality in the subway station; however the air quality in the subway tunnel is degraded. The subway tunnel has high CO2 concentration and indoor particulate matter (PM) value. The Indoor Air Quality (IAQ) level in subway environment degrades by increasing the frequency of the train operation and the number of the train. The ventilation systems of the subway tunnel need improvements to have better air-quality. Numerical analyses might be effective tools to analyze the performance of subway twin-track tunnel ventilation systems. An existing subway twin-track tunnel in the metropolitan Seoul subway system is chosen for the numerical simulations. The ANSYS CFX software is used for unsteady computations of the airflow inside the twin-track tunnel when the train moves. The airflow inside the tunnel is simulated when one train runs and two trains run at the same time in the tunnel. The piston-effect inside the tunnel is analyzed when all shafts function as the natural ventilation shaft. The supplied air through the shafts is mixed with the pollutant air in the tunnel. The pollutant air is exhausted by the mechanical ventilation shafts. The supplied and discharged airs are balanced when only one train runs in the twin-track tunnel. The pollutant air in the tunnel is high when two trains run simultaneously in opposite direction and all shafts functioned as the natural shaft cases when there are no electrical power supplies in the shafts. The remained pollutant air inside the tunnel enters into the station platform when the doors are opened.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=indoor%20air%20quality" title="indoor air quality">indoor air quality</a>, <a href="https://publications.waset.org/search?q=subway%20twin-track%20tunnel" title=" subway twin-track tunnel"> subway twin-track tunnel</a>, <a href="https://publications.waset.org/search?q=train-induced%20wind" title=" train-induced wind"> train-induced wind</a> </p> <a href="https://publications.waset.org/3116/ventilation-efficiency-in-the-subway-environment-for-the-indoor-air-quality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/3116/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/3116/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/3116/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/3116/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/3116/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/3116/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/3116/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/3116/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/3116/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/3116/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/3116.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">4343</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">265</span> Effect of Aging Treatment on Mechanical Properties of Non-Flammable AZ91D Mg Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Ju%20Hyun%20Won">Ju Hyun Won</a>, <a href="https://publications.waset.org/search?q=Hyun%20Woo%20Lee"> Hyun Woo Lee</a>, <a href="https://publications.waset.org/search?q=Seok%20Hong%20Min"> Seok Hong Min</a>, <a href="https://publications.waset.org/search?q=Tae%20Kwon%20Ha"> Tae Kwon Ha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Microstructure and mechanical properties of AZ91D Mg alloys for nonflammable use, containing Ca and Y, were investigated in this study. Solid solution treatment of AZ91D Mg alloy with Ca and Y was successfully conducted at 420oC and supersaturated microstructure with almost all beta phases resolved into matrix was obtained. After solid solution treatment, the alloy was annealed at temperatures of 180 and 200oC for time intervals from 1 min to 48 hrs and hardness of each condition was measured by micro-Vickers method. Peak aging conditions were deduced from the results as at the temperature of 200oC for 10 hrs. Hot rolling was also carried out at 400oC by the reduction ratio of 0.6 through 5 passes followed by recrystallization treatment. Tensile and compressive properties were measured at room temperature on the specimens of each process, i.e. as-cast, solution treatment, hot rolling, and recrystallization. <p
