study investigates experimentally the effects of flanges (transverse walls) on the lateral in-plane response of brick masonry walls. The experimental work included lateral in-plane quasi-static cyclic tests on full-scale walls (both with & without flanges). The flanges were introduced at both ends of the in-plane wall. In particular the damage mechanism, lateral in-plane stiffness & strength, deformability and energy dissipation of the two classes of walls are compared and the differences are quantified to help understand the effects of flanges on the in-plane response of masonry walls. The available analytical models for the in-plane shear strength & deformation evaluation of masonry walls are critically analyzed. Recommendations are made for the lateral in-plane capacity assessment of brick masonry walls including the contribution of transverse walls. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brick%20masonry" title="brick masonry">brick masonry</a>, <a href="https://publications.waset.org/abstracts/search?q=damage%20mechanism" title=" damage mechanism"> damage mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=flanges%20effects" title=" flanges effects"> flanges effects</a>, <a href="https://publications.waset.org/abstracts/search?q=in-plane%20response" title=" in-plane response"> in-plane response</a> </p> <a href="https://publications.waset.org/abstracts/33495/evaluation-of-flange-effects-on-the-lateral-in-plane-response-of-brick-masonry-walls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33495.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">382</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">1296</span> A Survey on Compression Methods for Table Constraints</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Gharbi">N.

Table constraints are important for modeling parts of many problems since they list all combinations of allowed or forbidden values.

When the Hall voltage is measured for linear displacement, it is converted to angular displacement using arctangent function, which requires a large lookup table. In this paper, a lookup table reduction technique is presented for angle measurement. When the input of the lookup table is small within a certain threshold, the change of the outputs with respect to the change of the inputs is relatively small. Thus, several inputs can share same output, which significantly reduce the lookup table size. Its error analysis was also performed, and the threshold was determined so as to maintain the error less than 1°. When the Hall voltage has 11-bit resolution, the lookup table size is reduced from 1,024 samples to 279 samples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hall%20sensor" title="hall sensor">hall sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=angle%20measurement" title=" angle measurement"> angle measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=lookup%20table" title=" lookup table"> lookup table</a>, <a href="https://publications.waset.org/abstracts/search?q=arctangent" title=" arctangent"> arctangent</a> </p> <a href="https://publications.waset.org/abstracts/60862/lookup-table-reduction-and-its-error-analysis-of-hall-sensor-based-rotation-angle-measurement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60862.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">337</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">1294</span> Derivation of Technology Element for Automation in Table Formwork in a Tall Building Construction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Junehyuck%20Lee">Junehyuck Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Dongmin%20Lee"> Dongmin Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Hunhee%20Cho"> Hunhee Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyung-In%20Kang"> Kyung-In Kang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A table formwork method has recently been widely applied in reinforced concrete structures in a tall building construction to improve safety and productivity.

Although most of parents teach deaf children communication skills in early life, but rarely teach the deficits of balance. The purpose of this study was to investigate whether static balance improved after table tennis training. Table tennis training was provided four times a week for eight weeks to two 12-year-old deaf children. The table tennis training included crossover footwork, sideway attack, backhand block-sideways-flutter forehand attack, and one-on-one tight training. Data were gathered weekly and statistical comparisons were made with a paired t-test. We observed that the dominant leg is better than the non-dominant leg in static balance and girl balance ability is better than boy. The final result shows that table tennis training significantly improves the deaf children’s static balance performance. It indicates that table tennis training on deaf children helps the static balance ability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deaf%20children" title="deaf children">deaf children</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20balance" title=" static balance"> static balance</a>, <a href="https://publications.waset.org/abstracts/search?q=table%20tennis" title=" table tennis"> table tennis</a>, <a href="https://publications.waset.org/abstracts/search?q=vestibular%20structure" title=" vestibular structure"> vestibular structure</a> </p> <a href="https://publications.waset.org/abstracts/45989/the-effect-of-static-balance-enhance-by-table-tennis-training-intervening-on-deaf-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45989.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">433</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">1292</span> Preparation of Regional Input-Output Table for Fars Province in 2011: GRIT1Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Akbarzadeh">Maryam Akbarzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=F.%20Esmaeilzadeh"> F.

Obtained estimates by non-statistical methods have low confidence coefficient. Therefore, integrated methods for this purpose are suggested by recent input–output studies. In this study, first GRIT method is introduced as an appropriate integrated method for preparation of input-output table of Fars province. Next, input-output table is prepared for Fars province using this method. Therefore, this study is based on input-output table of national economy in 2001. Necessary modifications performed in the field of changes at level of prices and differences of regional trade compared with other areas at national level. Moreover, up to date statistics and information and technical experts view on the various economic sectors along with input-output table 33 was used in 2011 followed by investigation of general structure of the province economy based on the amounts of added value obtained from this table. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=grit" title="grit">grit</a>, <a href="https://publications.waset.org/abstracts/search?q=input-output" title=" input-output"> input-output</a>, <a href="https://publications.waset.org/abstracts/search?q=table" title=" table"> table</a>, <a href="https://publications.waset.org/abstracts/search?q=regional" title=" regional "> regional </a> </p> <a href="https://publications.waset.org/abstracts/3237/preparation-of-regional-input-output-table-for-fars-province-in-2011-grit1method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3237.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">260</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1291</span> Dynamic Stability of Axially Moving Viscoelastic Plates under Nonuniform in-Plane Edge Excitations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20H.%20Young">T.

Chiu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates the parametric stability of an axially moving web subjected to nonuniform in-plane edge excitations on two opposite, simply-supported edges. The web is modeled as a viscoelastic plate whose constitutive relation obeys the Kelvin-Voigt model, and the in-plane edge excitations are expressed as the sum of a static tension and a periodical perturbation. Due to the in-plane edge excitations, the moving plate may bring about parametric instability under certain situations. First, the in-plane stresses of the plate due to the nonuniform edge excitations are determined by solving the in-plane forced vibration problem. Then, the dependence on the spatial coordinates in the equation of transverse motion is eliminated by the generalized Galerkin method, which results in a set of discretized system equations in time. Finally, the method of multiple scales is utilized to solve the set of system equations analytically if the periodical perturbation of the in-plane edge excitations is much smaller as compared with the static tension of the plate, from which the stability boundaries of the moving plate are obtained. Numerical results reveal that only combination resonances of the summed-type appear under the in-plane edge excitations considered in this work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=axially%20moving%20viscoelastic%20plate" title="axially moving viscoelastic plate">axially moving viscoelastic plate</a>, <a href="https://publications.waset.org/abstracts/search?q=in-plane%20periodic%20excitation" title=" in-plane periodic excitation"> in-plane periodic excitation</a>, <a href="https://publications.waset.org/abstracts/search?q=nonuniformly%20distributed%20edge%20tension" title=" nonuniformly distributed edge tension"> nonuniformly distributed edge tension</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20stability" title=" dynamic stability"> dynamic stability</a> </p> <a href="https://publications.waset.org/abstracts/26548/dynamic-stability-of-axially-moving-viscoelastic-plates-under-nonuniform-in-plane-edge-excitations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26548.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">322</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1290</span> Impact of Out-of-Plane Stiffness of the Diaphragm on Deflection of Wood Light-Frame Shear Walls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20M.%20Bagheri">M.

Where research has lacked is in evaluating the impact of out-of-plane raigidity of the diaphragm on the deflection of shear walls. This study aims at investigating the effect of the diaphragm on the behavior of wood light-frame shear walls, in particular its out-of-plane rigidity was simulated by modeling the floors as beam. The out of plane stiffness of the diaphragm was investigated for idealized (infinitely stiff or flexible) as well as “realistic”. The results showed reductions in the shear wall deflection in the magnitude of approximately 80% considering the out of plane rigidity of the diaphragm. It was also concluded that considering conservative estimates of out-of-plane stiffness might lead to a very significant reduction in deflection and that assuming the floor diaphragm to be infinitely rigid out of plan seems to be reasonable. For diaphragms supported on multiple panels, further reduction in the deflection was observed. More work, particularly at the experimental level, is needed to verify the finding obtained in the numerical investigation related to the effect of out of plane diaphragm stiffness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title="finite element analysis">finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral%20deflection" title=" lateral deflection"> lateral deflection</a>, <a href="https://publications.waset.org/abstracts/search?q=out-of-plane%20stiffness%20of%20the%20diaphragm" title=" out-of-plane stiffness of the diaphragm"> out-of-plane stiffness of the diaphragm</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20light-frame%20shear%20wall" title=" wood light-frame shear wall"> wood light-frame shear wall</a> </p> <a href="https://publications.waset.org/abstracts/106928/impact-of-out-of-plane-stiffness-of-the-diaphragm-on-deflection-of-wood-light-frame-shear-walls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106928.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">182</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">1289</span> Correlation between Physical Fitness and Performance and Grade of Table Tennis of Middle School Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yisong%20Cong">Yisong Cong</a>, <a href="https://publications.waset.org/abstracts/search?q=Mingming%20Guo"> Mingming Guo</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaozan%20Wang"> Xiaozan Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yizhi%20Zhang"> Yizhi Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Qingqing%20Yuan"> Qingqing Yuan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is to test the correlation between the Physical Fitness (PF) of middle school students and their performance and sports grade of table tennis. Methods: 398 middle school students from Shanghai Tongji No.2 Middle School participated in the study, including 232 boys and 166 girls. Each participant participated in the Chinese Students’ Physical Fitness Test (CSPFT), including BMI, 50-meter running, vital capacity, sitting body flexion, standing long jump, 800-meter running, 1000-meter running, pull-ups, and sit-ups. Test scores were converted to a percentage score according to the CSPFT guidelines. In addition, each student participated in the Nation Junior Table Tennis grade test, and completed the table tennis sports grade assessment of 1-9. Results: There is a significant positive correlation between the scores of multiple PF tests and the total scores of table tennis, such as BMI (r = 0.15, p < 0.01), standing long jump (r = 0.15, p < 0.05), 800-meter run (r = 0.02, p <0.01); The scores of multiple PF are positively correlated with table tennis grade, such as vital capacity (r = 0.1, p < 0.01) and 50-meter running (r = 0.18, p < 0.05). At the same time, the sit-ups performance showed a significant negative correlation with the table tennis performance (r = -0.08, p < 0.01); There is no significant correlation between the other PF indicators and the performance and grade of table tennis. Conclusions: This study shows that there is a corresponding relationship between some PF indicators of middle school students and their table tennis performance and table tennis grade，but the specific form and reason of the relationship need to be further explored. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=middle%20school%20students" title="middle school students">middle school students</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20fitness" title=" physical fitness"> physical fitness</a>, <a href="https://publications.waset.org/abstracts/search?q=table%20tennis%20grade" title=" table tennis grade"> table tennis grade</a>, <a href="https://publications.waset.org/abstracts/search?q=table%20tennis%20performance" title=" table tennis performance"> table tennis performance</a> </p> <a href="https://publications.waset.org/abstracts/126554/correlation-between-physical-fitness-and-performance-and-grade-of-table-tennis-of-middle-school-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126554.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">160</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">1288</span> The Influence of Strengthening on the Fundamental Frequency and Stiffness of a Confined Masonry Wall with an Opening for а Window</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emin%20Z.%20Mahmud">Emin Z.

The tests are realized in the laboratory of the Institute of Earthquake Engineering and Engineering Seismology (IZIIS) – Skopje. The specimens were examined separately on the shaking table, with uniaxial, in-plane excitation. After testing, samples were strengthened with GFRP (Glass Fiber Reinforced Plastic) and re-tested. This paper presents the observations from a series of shaking-table tests done on a 1:1 scaled confined masonry wall model, with opening for a window – specimens CMWuS (before strengthening) and CMWS (after strengthening). Frequency and stiffness changes before and after GFRP wall strengthening are analyzed. Definition of dynamic properties of the models was the first step of the experimental testing, which enabled acquiring important information about the achieved stiffness (natural frequencies) of the model. The natural frequency was defined in the Y direction of the model by applying resonant frequency search tests. It is important to mention that both specimens CMWuS and CMWS are subjected to the same effects. The initial frequency of the undamaged model CMWuS is 18.79 Hz, while at the end of the testing, the frequency decreased to 12.96 Hz. This emphasizes the reduction of the initial stiffness of the model due to damage, especially in the masonry and tie-beam to tie-column connection. After strengthening the damaged wall, the natural frequency increases to 14.67 Hz. This highlights the beneficial effect of strengthening. After completion of dynamic testing at CMWS, the natural frequency is reduced to 10.75 Hz. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=behaviour%20of%20masonry%20structures" title="behaviour of masonry structures">behaviour of masonry structures</a>, <a href="https://publications.waset.org/abstracts/search?q=Eurocode" title=" Eurocode"> Eurocode</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency" title=" frequency"> frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=masonry" title=" masonry"> masonry</a>, <a href="https://publications.waset.org/abstracts/search?q=shaking%20table%20test" title=" shaking table test"> shaking table test</a>, <a href="https://publications.waset.org/abstracts/search?q=strengthening" title=" strengthening"> strengthening</a> </p> <a href="https://publications.waset.org/abstracts/117054/the-influence-of-strengthening-on-the-fundamental-frequency-and-stiffness-of-a-confined-masonry-wall-with-an-opening-for-a-window" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117054.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">118</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">1287</span> Jordan Curves in the Digital Plane with Respect to the Connectednesses given by Certain Adjacency Graphs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Josef%20Slapal">Josef Slapal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Digital images are approximations of real ones and, therefore, to be able to study them, we need the digital plane Z2 to be equipped with a convenient structure that behaves analogously to the Euclidean topology on the real plane.

We introduce certain adjacency graphs on the digital plane and prove digital Jordan curves for them thus showing that the graphs provide convenient structures on Z2 for the study and processing of digital images. Further convenient structures including the wellknown Khalimsky and Marcus-Wyse adjacency graphs may be obtained as quotients of the graphs introduced. Since digital Jordan curves represent borders of objects in digital images, the adjacency graphs discussed may be used as background structures on the digital plane for solving the problems of digital image processing that are closely related to borders like border detection, contour filling, pattern recognition, thinning, etc. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20plane" title="digital plane">digital plane</a>, <a href="https://publications.waset.org/abstracts/search?q=adjacency%20graph" title=" adjacency graph"> adjacency graph</a>, <a href="https://publications.waset.org/abstracts/search?q=Jordan%20curve" title=" Jordan curve"> Jordan curve</a>, <a href="https://publications.waset.org/abstracts/search?q=quotient%20adjacency" title=" quotient adjacency"> quotient adjacency</a> </p> <a href="https://publications.waset.org/abstracts/65454/jordan-curves-in-the-digital-plane-with-respect-to-the-connectednesses-given-by-certain-adjacency-graphs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65454.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">379</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">1286</span> Study on Flexible Diaphragm In-Plane Model of Irregular Multi-Storey Industrial Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cheng-Hao%20Jiang">Cheng-Hao Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Mu-Xuan%20Tao"> Mu-Xuan Tao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The rigid diaphragm model may cause errors in the calculation of internal forces due to neglecting the in-plane deformation of the diaphragm. This paper thus studies the effects of different diaphragm in-plane models (including in-plane rigid model and in-plane flexible model) on the seismic performance of structures. Taking an actual industrial plant as an example, the seismic performance of the structure is predicted using different floor diaphragm models, and the analysis errors caused by different diaphragm in-plane models including deformation error and internal force error are calculated. Furthermore, the influence of the aspect ratio on the analysis errors is investigated. Finally, the code rationality is evaluated by assessing the analysis errors of the structure models whose floors were determined as rigid according to the code’s criterion. It is found that different floor models may cause great differences in the distribution of structural internal forces, and the current code may underestimate the influence of the floor in-plane effect. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=industrial%20plant" title="industrial plant">industrial plant</a>, <a href="https://publications.waset.org/abstracts/search?q=diaphragm" title=" diaphragm"> diaphragm</a>, <a href="https://publications.waset.org/abstracts/search?q=calculating%20error" title=" calculating error"> calculating error</a>, <a href="https://publications.waset.org/abstracts/search?q=code%20rationality" title=" code rationality"> code rationality</a> </p> <a href="https://publications.waset.org/abstracts/127256/study-on-flexible-diaphragm-in-plane-model-of-irregular-multi-storey-industrial-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127256.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">140</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">1285</span> Association Between Hip Internal and External Rotation Range of Motion and Low Back Pain in Table Tennis Players</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kaili%20Wang">Kaili Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Botao%20Zhang"> Botao Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Enming%20Zhang"> Enming Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Low back pain (LBP) is a common problem affecting athletes' training and competition. Although the association between a limited hip range of motion and prevalence of low back pain has been studied extensively, it has not been studied in table tennis. Aim: The main purposes of this study in table tennis players were (1) to investigate if there is a difference in hip internal rotation (HIR) and external rotation (HER) range of motion (ROM) between players with LBP and players without LBP and (2) to analyze the association between HIR and HER ROM and LBP. Methods: Forty-six table tennis players from the Chinese table tennis team were evaluated for passive maximum HIR and HER ROM. LBP was retrospectively recorded for the last 12 months before the date of ROM assessment by a physical therapist. The data were analyzed the difference in HIR and HER ROM between players with LBP and players without LBP by Mann-Whitney U test, and the association between the difference in HIR and HER ROM and LBP was analyzed via a binary logistic regression. Results: The 54% of players had developed LBP during the retrospective study period. Signiﬁcant diﬀerence between LBP group and the asymptomatic group for HIR ROM (z=4.007, p<0.001) was observed. Diﬀerence between LBP group and asymptomatic group for HER ROM (z=1.117, p=0.264) was not signiﬁcant. Players who had HIR ROM deficit had an increased risk of LBP compared with players without HIR ROM deficit (OR=5.344, 95%CI: 1.006-28.395, P=0.049). Conclusion: HIR ROM of a table tennis player with LBP was less than a table tennis player without LBP. Compared with player whose HIR ROM was normal, player who had HIR ROM deficit appeared to have a higher risk for LBP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assessment" title="assessment">assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=injury%20prevention" title=" injury prevention"> injury prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20back%20pain" title=" low back pain"> low back pain</a>, <a href="https://publications.waset.org/abstracts/search?q=table%20tennis%20players" title=" table tennis players"> table tennis players</a> </p> <a href="https://publications.waset.org/abstracts/154477/association-between-hip-internal-and-external-rotation-range-of-motion-and-low-back-pain-in-table-tennis-players" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154477.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">111</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">1284</span> Seismic Response of Structure Using a Three Degree of Freedom Shake Table</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ketan%20N.%20Bajad">Ketan N.

There are various experimental techniques such as pseudo-dynamic tests – nonlinear structural dynamic technique, real time pseudo dynamic test and shaking table test method that can be employed to verify the seismic performance of structures. Shake table is a device that is used for shaking structural models or building components which are mounted on it. It is a device that simulates a seismic event using existing seismic data and nearly truly reproducing earthquake inputs. This paper deals with the use of shaking table test method to check the response of structure subjected to earthquake. The various types of shake table are vertical shake table, horizontal shake table, servo hydraulic shake table and servo electric shake table. The goal of this experiment is to perform seismic analysis of a civil engineering structure with the help of 3 degree of freedom (i.e. in X Y Z direction) shake table. Three (3) DOF shaking table is a useful experimental apparatus as it imitates a real time desired acceleration vibration signal for evaluating and assessing the seismic performance of structure. This study proceeds with the proper designing and erection of 3 DOF shake table by trial and error method. The table is designed to have a capacity up to 981 Newton. Further, to study the seismic response of a steel industrial building, a proportionately scaled down model is fabricated and tested on the shake table. The accelerometer is mounted on the model, which is used for recording the data. The experimental results obtained are further validated with the results obtained from software. It is found that model can be used to determine how the structure behaves in response to an applied earthquake motion, but the model cannot be used for direct numerical conclusions (such as of stiffness, deflection, etc.) as many uncertainties involved while scaling a small-scale model. The model shows modal forms and gives the rough deflection values. The experimental results demonstrate shake table as the most effective and the best of all methods available for seismic assessment of structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accelerometer" title="accelerometer">accelerometer</a>, <a href="https://publications.waset.org/abstracts/search?q=three%20degree%20of%20freedom%20shake%20table" title=" three degree of freedom shake table"> three degree of freedom shake table</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20analysis" title=" seismic analysis"> seismic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20industrial%20shed" title=" steel industrial shed"> steel industrial shed</a> </p> <a href="https://publications.waset.org/abstracts/98669/seismic-response-of-structure-using-a-three-degree-of-freedom-shake-table" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98669.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">140</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">1283</span> Effectiveness of Lowering the Water Table as a Mitigation Measure for Foundation Settlement in Liquefiable Soils Using 1-g Scale Shake Table Test</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kausar%20Alam">Kausar Alam</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Yazdi"> Mohammad Yazdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Peiman%20Zogh"> Peiman Zogh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramin%20Motamed"> Ramin Motamed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An earthquake is an unpredictable natural disaster. It induces liquefaction, which causes considerable damage to the structure, life support, and piping systems because of ground settlement. As a result, people are incredibly concerned about how to resolve the situation. Previous researchers adopted different ground improvement techniques to reduce the settlement of the structure during earthquakes. This study evaluates the effectiveness of lowering the water table as a technique to mitigate foundation settlement in liquefiable soil. The performance will be evaluated based on foundation settlement and the reduction of excessive pore water pressure. In this study, a scaled model was prepared based on a full-scale shale table experiment conducted at the University of California, San Diego (UCSD). The model ground consists of three soil layers having a relative density of 55%, 45%, and 90%, respectively. A shallow foundation is seated over an unsaturated crust layer. After preparation of the model ground, the water table was measured to be at 45, 40, and 35 cm (from the bottom). Then, the input motions were applied for 10 seconds, with a peak acceleration of 0.25g and a constant frequency of 2.73 Hz. Based on the experimental results, the effectiveness of the lowering water table in reducing the foundation settlement and excess pore water pressure was evident. The foundation settlement was reduced from 50 mm to 5 mm. In addition, lowering the water table as a mitigation measure is a cost-effective way to decrease liquefaction-induced building settlement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=foundation%20settlement" title="foundation settlement">foundation settlement</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20water%20table" title=" ground water table"> ground water table</a>, <a href="https://publications.waset.org/abstracts/search?q=liquefaction" title=" liquefaction"> liquefaction</a>, <a href="https://publications.waset.org/abstracts/search?q=hake%20table%20test" title=" hake table test"> hake table test</a> </p> <a href="https://publications.waset.org/abstracts/152050/effectiveness-of-lowering-the-water-table-as-a-mitigation-measure-for-foundation-settlement-in-liquefiable-soils-using-1-g-scale-shake-table-test" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152050.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">113</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">1282</span> The Influence of Strengthening on the Fundamental Frequency and Stiffness of a Confined Masonry Wall with an Opening for а Door</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emin%20Z.%20Mahmud">Emin Z.

The flow visualization and velocity measurements were respectively carried out using laser Doppler velocimetry (LDV) and particle image velocimetry (PIV). In addition, three-dimensional (3D) plane jet numerical simulations were performed using ANSYS Fluent, a commercially available computational fluid dynamics (CFD) software application. We found that the spreads of jets perturbed by large delta tabs and round tabs were larger than those produced by the other tabs tested. Additionally, it was determined that a plane jet with square tabs had the smallest jet spread downstream, and the jet’s centerline velocity was larger than those of jets perturbed by the other tabs tested. It was also observed that the spanwise vortical structure of a plane jet with tabs disappeared completely. Good agreement was found between the experimental and numerical simulation velocity profiles in the area near the nozzle exit when the laminar flow model was used. However, we also found that large eddy simulation (LES) is better at predicting the developing flow field of a plane jet than the laminar and the standard k-ε turbulent models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plane%20jet" title="plane jet">plane jet</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20control" title=" flow control"> flow control</a>, <a href="https://publications.waset.org/abstracts/search?q=tab" title=" tab"> tab</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20measurement" title=" flow measurement"> flow measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a> </p> <a href="https://publications.waset.org/abstracts/54632/control-of-a-plane-jet-spread-by-tabs-at-the-nozzle-exit" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54632.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">334</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">1280</span> Improve B-Tree Index’s Performance Using Lock-Free Hash Table</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhanfeng%20Ma">Zhanfeng Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhiping%20Xiong"> Zhiping Xiong</a>, <a href="https://publications.waset.org/abstracts/search?q=Hu%20Yin"> Hu Yin</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhengwei%20She"> Zhengwei She</a>, <a href="https://publications.waset.org/abstracts/search?q=Aditya%20P.%20Gurajada"> Aditya P.

However, there are extra overheads to maintain a separate hash index, for example, hash mapping for all data records must always be maintained, which results in more memory space consumption; locking, logging and other mechanisms are needed to guarantee ACID, which affects the concurrency and scalability of the system. To relieve the overheads, Hash Cached B-tree (HCB) index is proposed in this paper, which consists of a standard disk-based B-tree index and an additional in-memory lock-free hash table. Initially, only the B-tree index is constructed for all data records, the hash table is built on the fly based on runtime workload, only data records accessed by point queries are indexed using hash table, this helps reduce the memory footprint. Changes to hash table are done using compare-and-swap (CAS) without performing locking and logging, this helps improve the concurrency and avoid contention.

This study was conducted on 200 subjects to evaluate if any correlation exists between the variation of angulation of palatal throat form and the relative parallelism of occlusal plane to ala-tragal line at different tragal levels. A Custom made Occlusal Plane Analyzer was used to check the parallelism between the ala-tragal line and occlusal plane. A lateral cephalogram was shot for each subject to measure the angulation of the palatal throat form. Fisher’s exact test was used to evaluate the correlation between the angulation of the palatal throat form and the relative parallelism of occlusal plane to the ala tragal line. Also, a classification was formulated for the palatal throat form, based on confidence interval. From the results of the study, the inferior part, middle part and superior part of the tragus were seen as the reference points in 49.5%, 32% and 18.5% of the subjects respectively. Class I palatal throat form (41degree-50 degree), Class II palatal throat form (below 41 degree) and Class III palatal throat form (above 50 degree) were seen in 42%, 43% and 15% of the subjects respectively. It was also concluded that there is no significant correlation between the variation in the angulations of the palatal throat form and the relative parallelism of occlusal plane to the ala-tragal line. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ala-Tragal%20line" title="Ala-Tragal line">Ala-Tragal line</a>, <a href="https://publications.waset.org/abstracts/search?q=occlusal%20plane" title=" occlusal plane"> occlusal plane</a>, <a href="https://publications.waset.org/abstracts/search?q=palatal%20throat%20form" title=" palatal throat form"> palatal throat form</a>, <a href="https://publications.waset.org/abstracts/search?q=cephalometry" title=" cephalometry "> cephalometry </a> </p> <a href="https://publications.waset.org/abstracts/25452/relevance-of-the-variation-in-the-angulation-of-palatal-throat-form-to-the-orientation-of-the-occlusal-plane-a-cephalometric-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25452.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">310</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">1278</span> Traverse Surveying Table Simple and Sure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Fallah">Hamid Fallah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Creating surveying stations is the first thing that a surveyor learns; they can use it for control and implementation in projects such as buildings, roads, tunnels, monitoring, etc., whatever is related to the preparation of maps.

In this article, we will propose a clustering based and centralized routing table protocol of TC (CBCRT) which delegates a leader node that will encapsulate a single routing table in every cluster nodes. Hence, if a node wants to send packets to the sink, it requests the information's routing table of the current cluster from the node leader in order to root the packet. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mobile%20wireless%20sensor%20networks" title="mobile wireless sensor networks">mobile wireless sensor networks</a>, <a href="https://publications.waset.org/abstracts/search?q=routing" title=" routing"> routing</a>, <a href="https://publications.waset.org/abstracts/search?q=topology%20of%20control" title=" topology of control"> topology of control</a>, <a href="https://publications.waset.org/abstracts/search?q=protocols" title=" protocols"> protocols</a> </p> <a href="https://publications.waset.org/abstracts/54518/clustering-based-and-centralized-routing-table-topology-of-control-protocol-in-mobile-wireless-sensor-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54518.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">274</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">1276</span> Taylor’s Law and Relationship between Life Expectancy at Birth and Variance in Age at Death in Period Life Table</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20A.%20Swanson">David A.

Tedrow</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Taylor’s Law is a widely observed empirical pattern that relates variances to means in sets of non-negative measurements via an approximate power function, which has found application to human mortality. This study adds to this research by showing that Taylor’s Law leads to a model that reasonably describes the relationship between life expectancy at birth (e0, which also is equal to mean age at death in a life table) and variance at age of death in seven World Bank regional life tables measured at two points in time, 1970 and 2000. Using as a benchmark a non-random sample of four Japanese female life tables covering the period from 1950 to 2004, the study finds that the simple linear model provides reasonably accurate estimates of variance in age at death in a life table from e0, where the latter range from 60.9 to 85.59 years. Employing 2017 life tables from the Human Mortality Database, the simple linear model is used to provide estimates of variance at age in death for six countries, three of which have high e0 values and three of which have lower e0 values. The paper provides a substantive interpretation of Taylor’s Law relative to e0 and concludes by arguing that reasonably accurate estimates of variance in age at death in a period life table can be calculated using this approach, which also can be used where e0 itself is estimated rather than generated through the construction of a life table, a useful feature of the model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=empirical%20pattern" title="empirical pattern">empirical pattern</a>, <a href="https://publications.waset.org/abstracts/search?q=mean%20age%20at%20death%20in%20a%20life%20table" title=" mean age at death in a life table"> mean age at death in a life table</a>, <a href="https://publications.waset.org/abstracts/search?q=mean%20age%20of%20a%20stationary%20population" title=" mean age of a stationary population"> mean age of a stationary population</a>, <a href="https://publications.waset.org/abstracts/search?q=stationary%20population" title=" stationary population"> stationary population</a> </p> <a href="https://publications.waset.org/abstracts/138835/taylors-law-and-relationship-between-life-expectancy-at-birth-and-variance-in-age-at-death-in-period-life-table" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138835.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">330</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">1275</span> Architecture Performance-Related Design Based on Graphic Parameterization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wenzhe%20Li">Wenzhe Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaoyu%20Ying"> Xiaoyu Ying</a>, <a href="https://publications.waset.org/abstracts/search?q=Grace%20Ding"> Grace Ding</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Architecture plane form is an important consideration in the design of green buildings due to its significant impact on energy performance. The most effective method to consider energy performance in the early design stages is parametric modelling. This paper presents a methodology to program plane forms using MATLAB language, generating 16 kinds of plane forms by changing four designed parameters. DesignBuilder (an energy consumption simulation software) was proposed to simulate the energy consumption of the generated planes. A regression mathematical model was established to study the relationship between the plane forms and their energy consumption. The main finding of the study suggested that there was a cubic function relationship between the depth-ratio of U-shaped buildings and energy consumption, and there is also a cubic function relationship between the width-ratio and energy consumption. In the design, the depth-ratio of U-shaped buildings should not be less than 2.5, and the width-ratio should not be less than 2. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=graphic%20parameterization" title="graphic parameterization">graphic parameterization</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20building%20design" title=" green building design"> green building design</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20model" title=" mathematical model"> mathematical model</a>, <a href="https://publications.waset.org/abstracts/search?q=plane%20form" title=" plane form"> plane form</a> </p> <a href="https://publications.waset.org/abstracts/107866/architecture-performance-related-design-based-on-graphic-parameterization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107866.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">153</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">1274</span> An Optimized Approach to Generate the Possible States of Football Tournaments Final Table</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mouslem%20Damkhi">Mouslem Damkhi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper focuses on possible states of a football tournament final table according to the number of participating teams. Each team holds a position in the table with which it is possible to determine the highest and lowest points for that team. This paper proposes an optimized search space based on the minimum and maximum number of points which can be gained by each team to produce and enumerate the possible states for a football tournament final table. The proposed search space minimizes producing the invalid states which cannot occur during a football tournament. The generated states are filtered by a validity checking algorithm which seeks to reach a tournament graph based on a generated state. Thus, the algorithm provides a way to determine which team’s wins, draws and loses values guarantee a particular table position. The paper also presents and discusses the experimental results of the approach on the tournaments with up to eight teams. Comparing with a blind search algorithm, our proposed approach reduces generating the invalid states up to 99.99%, which results in a considerable optimization in term of the execution time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=combinatorics" title="combinatorics">combinatorics</a>, <a href="https://publications.waset.org/abstracts/search?q=enumeration" title=" enumeration"> enumeration</a>, <a href="https://publications.waset.org/abstracts/search?q=graph" title=" graph"> graph</a>, <a href="https://publications.waset.org/abstracts/search?q=tournament" title=" tournament"> tournament</a> </p> <a href="https://publications.waset.org/abstracts/125649/an-optimized-approach-to-generate-the-possible-states-of-football-tournaments-final-table" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125649.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">122</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">1273</span> Shaking Table Test and Seismic Performance Evaluation of Spring Viscous Damper Cable System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asad%20Naeem">Asad Naeem</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinkoo%20Kim"> Jinkoo Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research proposes a self-centering passive damping system consisting of a spring viscous damper linked with a preloaded tendon.

Rapidly increasing in data size and big data are the most important issue today to make an analysis of this data. map reduce is used to analyze data and get more helpful information by using two simple functions map and reduce it's only written by the programmer, and it includes load balancing , fault tolerance and high scalability. The most important operation in data analysis are join, but map reduce is not directly support join. This paper explains two-way map-reduce join algorithm, semi-join and per split semi-join, and proposes new algorithm hash semi-join that used hash table to increase performance by eliminating unused records as early as possible and apply join using hash table rather than using map function to match join key with other data table in the second phase but using hash tables isn't affecting on memory size because we only save matched records from the second table only. Our experimental result shows that using a hash table with hash semi-join algorithm has higher performance than two other algorithms while increasing the data size from 10 million records to 500 million and running time are increased according to the size of joined records between two tables. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=map%20reduce" title="map reduce">map reduce</a>, <a href="https://publications.waset.org/abstracts/search?q=hadoop" title=" hadoop"> hadoop</a>, <a href="https://publications.waset.org/abstracts/search?q=semi%20join" title=" semi join"> semi join</a>, <a href="https://publications.waset.org/abstracts/search?q=two%20way%20join" title=" two way join"> two way join</a> </p> <a href="https://publications.waset.org/abstracts/31822/new-two-way-map-reduce-join-algorithm-hash-semi-join" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31822.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">513</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">1271</span> Efficacy of Erector Spinae Plane Block for Postoperative Pain Management in Coronary Artery Bypass Graft Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Santosh%20Sharma%20Parajuli">Santosh Sharma Parajuli</a>, <a href="https://publications.waset.org/abstracts/search?q=Diwas%20Manandhar"> Diwas Manandhar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Perioperative pain management plays an integral part in patients undergoing cardiac surgery. We studied the effect of Erector Spinae Plane block on acute postoperative pain reduction and 24 hours opioid consumption in adult cardiac surgical patients. Methods: Twenty-five adult cardiac surgical patients who underwent cardiac surgery with sternotomy in whom ESP catheters were placed preoperatively were kept in group E, and the other 25 patients who had undergone cardiac surgery without ESP catheter and pain management done with conventional opioid injection were placed in group C. Fentanyl was used for pain management. The primary study endpoint was to compare the consumption of fentanyl and to assess the numeric rating scale in the postoperative period in the first 24 hours in both groups. Results: The 24 hours fentanyl consumption was 43.00±51.29 micrograms in the Erector Spinae Plane catheter group and 147.00±60.94 micrograms in the control group postoperatively which was statistically significant (p <0.001). The numeric rating scale was also significantly reduced in the Erector Spinae Plane group compared to the control group in the first 24 hours postoperatively. Conclusion: Erector Spinae Plane block is superior to the conventional opioid injection method for postoperative pain management in CABG patients. Erector Spinae Plane block not only decreases the overall opioid consumption but also the NRS score in these patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=erector" title="erector">erector</a>, <a href="https://publications.waset.org/abstracts/search?q=spinae" title=" spinae"> spinae</a>, <a href="https://publications.waset.org/abstracts/search?q=plane" title=" plane"> plane</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20rating%20scale" title=" numerical rating scale"> numerical rating scale</a> </p> <a href="https://publications.waset.org/abstracts/167320/efficacy-of-erector-spinae-plane-block-for-postoperative-pain-management-in-coronary-artery-bypass-graft-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167320.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">67</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">1270</span> Stability of Out-Of-Plane Equilibrium Points in the Elliptic Restricted Three-Body Problem with Oblateness up to Zonal Harmonic J₄ of Both Primaries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kanshio%20Richard%20Tyokyaa">Kanshio Richard Tyokyaa</a>, <a href="https://publications.waset.org/abstracts/search?q=Jagadish%20Singh"> Jagadish Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we examined the location and stability of Out-Of-Plane Equilibrium points in the elliptic restricted three-body problem of an infinitesimal body when both primaries are taken as oblate spheroids with oblateness up to zonal harmonic J₄.

The results were used in the calibration/validation of the numerical model created on the basis of the 1:10 scale model built for shake table testing. 3D distinct element model was developed that represents the linear and nonlinear behavior of the shake table model as closely as possible during experimental tests. Results of numerical analyses with those from the experimental program were compared and discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20analysis" title="dynamic analysis">dynamic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=non-linear%20modeling" title=" non-linear modeling"> non-linear modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=shake%20table%20tests" title=" shake table tests"> shake table tests</a>, <a href="https://publications.waset.org/abstracts/search?q=masonry" title=" masonry"> masonry</a> </p> <a href="https://publications.waset.org/abstracts/30824/experimental-and-numerical-analysis-of-mustafa-pasa-mosque-in-skopje" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30824.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">426</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">1268</span> Improving Traditional Methods of Handling Fish from Integrated Pond Culture Systems in Monai Village, New Bussa, Nigeria </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olokor%20O.%20Julius">Olokor O.

Unlike the conventional table, the improved table was screened against flies and indiscriminate touch by customers. The fishes were displayed on both tables for 9 hours and quality attributes were monitored hourly by trained panelists. For C. gariepinus, the gills, and intestine recorded faster deterioration starting from the fourth and fifth hours while those on the improved table were prolonged by one hour. Scores for skin brightness and texture did not indicate quality deterioration throughout the display period. However, at the end of the storage time, samples on the improved table recorded 1.5 x 104 cfu/g while samples in unscreened table recorded 3.7 x 10 7 cfu/g. The study shows how simple modifications of a traditional practice can help extend keeping qualities of farmed fish, reduce health hazards in local communities where there is no electricity to preserve fish in whatever form despite a boom in aquaculture. Monai community has a fish farm estate of over 200 small holder farmers with annual output capacity of over $10 million dollars. The simple improvement made to farmers practice in this study is to ensure Community hygiene and boost income of peasant fish farmers by improving the market quality of their products. <p
