Table constraints are important for modeling parts of many problems since they list all combinations of allowed or forbidden values. However, they admit practical limitations because they are sometimes too large to be represented in a direct way. In this paper, we present a survey of the different categories of the proposed approaches to compress table constraints in order to reduce both space and time complexities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constraint%20programming" title="constraint programming">constraint programming</a>, <a href="https://publications.waset.org/abstracts/search?q=compression" title=" compression"> compression</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20mining" title=" data mining"> data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=table%20constraints" title=" table constraints"> table constraints</a> </p> <a href="https://publications.waset.org/abstracts/49933/a-survey-on-compression-methods-for-table-constraints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49933.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">325</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6620</span> Lookup Table Reduction and Its Error Analysis of Hall Sensor-Based Rotation Angle Measurement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Young-San%20Shin">Young-San Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Seongsoo%20Lee"> Seongsoo Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hall sensor is widely used to measure rotation angle. 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">336</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6619</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">6617</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">6616</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">6615</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">6614</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">6613</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">6612</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. The hash table is also optimized to be cache conscious. HCB index is implemented in SAP ASE database, compared with the standard B-tree index, early experiments and customer adoptions show significant performance improvement. This paper provides an overview of the design of HCB index and reports the experimental results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=B-tree" title="B-tree">B-tree</a>, <a href="https://publications.waset.org/abstracts/search?q=compare-and-swap" title=" compare-and-swap"> compare-and-swap</a>, <a href="https://publications.waset.org/abstracts/search?q=lock-free%20hash%20table" title=" lock-free hash table"> lock-free hash table</a>, <a href="https://publications.waset.org/abstracts/search?q=point%20queries" title=" point queries"> point queries</a>, <a href="https://publications.waset.org/abstracts/search?q=range%20queries" title=" range queries"> range queries</a>, <a href="https://publications.waset.org/abstracts/search?q=SAP%20ASE%20database" title=" SAP ASE database"> SAP ASE database</a> </p> <a href="https://publications.waset.org/abstracts/72665/improve-b-tree-indexs-performance-using-lock-free-hash-table" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72665.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">286</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">6611</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.

The main TCAM-design challenge is to decrease the power consumption associated with the large amount of parallel active circuitry, without compromising with speed or memory density. Furthermore, when the channel length decreases, leakage power becomes more significant, and it can even dominate dynamic power at lower technologies. In this paper, we propose a TCAM-design technique, called Virtual Power Supply technique that reduces the leakage by a substantial amount. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=match%20line%20%28ML%29" title="match line (ML)">match line (ML)</a>, <a href="https://publications.waset.org/abstracts/search?q=search%20line%20%28SL%29" title=" search line (SL)"> search line (SL)</a>, <a href="https://publications.waset.org/abstracts/search?q=ternary%20content%20addressable%20memory%20%28TCAM%29" title=" ternary content addressable memory (TCAM)"> ternary content addressable memory (TCAM)</a>, <a href="https://publications.waset.org/abstracts/search?q=Leakage%20power%20%28LP%29" title=" Leakage power (LP)"> Leakage power (LP)</a> </p> <a href="https://publications.waset.org/abstracts/52223/ternary-content-addressable-memory-cell-with-a-leakage-reduction-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52223.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">299</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">6609</span> Clustering Based and Centralized Routing Table Topology of Control Protocol in Mobile Wireless Sensor Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mbida%20Mohamed">Mbida Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Ezzati%20Abdellah"> Ezzati Abdellah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A strong challenge in the wireless sensor networks (WSN) is to save the energy and have a long life time in the network without having a high rate of loss information.

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">273</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">6608</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">6607</span> Development of Fuzzy Logic Control Ontology for E-Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Sollehhuddin%20A.%20Jalil">Muhammad Sollehhuddin A.

Ontology is one of the focus areas in the field of Information Retrieval. The purpose of an ontology is to describe a conceptual representation of concepts and their relationships within a particular domain. In other words, ontology provides a common vocabulary for anyone who needs to share information in the domain. There are several ontology domains in various fields including engineering and non-engineering knowledge. However, there are only a few available ontology for engineering knowledge. Fuzzy logic as engineering knowledge is still not available as ontology domain. In general, fuzzy logic requires step-by-step guidelines and instructions of lab experiments. In this study, we presented domain ontology for Fuzzy Logic Control (FLC) knowledge. We give Table of Content (ToC) with middle strategy based on the Uschold and King method to develop FLC ontology. The proposed framework is developed using Protégé as the ontology tool. The Protégé’s ontology reasoner, known as the Pellet reasoner is then used to validate the presented framework. The presented framework offers better performance based on consistency and classification parameter index. In general, this ontology can provide a platform to anyone who needs to understand FLC knowledge. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=engineering%20knowledge" title="engineering knowledge">engineering knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20logic%20control%20ontology" title=" fuzzy logic control ontology"> fuzzy logic control ontology</a>, <a href="https://publications.waset.org/abstracts/search?q=ontology%20development" title=" ontology development"> ontology development</a>, <a href="https://publications.waset.org/abstracts/search?q=table%20of%20content" title=" table of content"> table of content</a> </p> <a href="https://publications.waset.org/abstracts/54717/development-of-fuzzy-logic-control-ontology-for-e-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54717.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">299</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">6606</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">6605</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">6603</span> Experimental and Numerical Analysis of Mustafa Paşa Mosque in Skopje</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ozden%20Saygili">Ozden Saygili</a>, <a href="https://publications.waset.org/abstracts/search?q=Eser%20Cakti"> Eser Cakti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The masonry building stock in Istanbul and in other cities of Turkey are exposed to significant earthquake hazard. Determination of the safety of masonry structures against earthquakes is a complex challenge. This study deals with experimental tests and non-linear dynamic analysis of masonry structures modeled through discrete element method. The 1:10 scale model of Mustafa Paşa Mosque was constructed and the data were obtained from the sensors on it during its testing on the shake table. 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.

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 class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fish%20spoilage" title="fish spoilage">fish spoilage</a>, <a href="https://publications.waset.org/abstracts/search?q=improved%20handling" title=" improved handling"> improved handling</a>, <a href="https://publications.waset.org/abstracts/search?q=income%20generation" title=" income generation"> income generation</a>, <a href="https://publications.waset.org/abstracts/search?q=retail%20table" title=" retail table"> retail table</a> </p> <a href="https://publications.waset.org/abstracts/20715/improving-traditional-methods-of-handling-fish-from-integrated-pond-culture-systems-in-monai-village-new-bussa-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20715.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">448</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">6601</span> Disturbance Observer-Based Predictive Functional Critical Control of a Table Drive System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Toshiyuki%20Satoh">Toshiyuki Satoh</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroki%20Hara"> Hiroki Hara</a>, <a href="https://publications.waset.org/abstracts/search?q=Naoki%20Saito"> Naoki Saito</a>, <a href="https://publications.waset.org/abstracts/search?q=Jun-ya%20Nagase"> Jun-ya Nagase</a>, <a href="https://publications.waset.org/abstracts/search?q=Norihiko%20Saga"> Norihiko Saga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper addresses a control system design for a table drive system based on the disturbance observer (DOB)-based predictive functional critical control (PFCC).

Becouse to low melting temperature it is also used to decreasing of the temperature of thermal annealing during fabrication of ceramic goods [1,2]. So called “Porceline or China stones” - quartz-sericite (muscovite) minerals is also can be used for prevention of deformation as the content of Kalium oxide in muscovite is rather high (SiO2, + KAl2[AlSi3O10](OH)2). [3] . To estimation of possibility of use of this mineral for ceramic manufacture, in the presented article the influence of thermal processing on phase and a chemical content of this raw material is investigated. As well as to other ceramic raw materials (kaoline, white burning clays) the basic requirements of the industry to quality of "a porcelain stone» are following: small size of particles, relative high uniformity of disrtribution of components and phase, white color after burning, small content of colorant oxides or chromophores (Fe2O3, FeO, TiO2, etc) [4,5]. In the presented work natural minerale from the Boynaksay deposit (Uzbekistan) is investigated. The samples was mechanically polished for investigation by Scanning Electron Microscope. Powder with size of particle up to 63 μm was used to X-ray diffractometry and chemical analysis. The annealing of samples was performed at 900, 1120, 1350oC during 1 hour. Chemical composition of Boynaksay raw material according to chemical analysis presented in the table 1. For comparison the composition of raw materials from Russia and USA are also presented. In the Boynaksay quartz – sericite the average parity of quartz and sericite makes 55-60 and 30-35 % accordingly. The distribution of quartz and sericite phases in raw material was investigated using electron probe scanning electronic microscope «JEOL» JXA-8800R. In the figure 1 the scanning electron microscope (SEM) micrograps of the surface and the distributions of Al, Si and K atoms in the sample are presented. As it seen small granular, white and dense mineral includes quartz, sericite and small content of impurity minerals. Basically, crystals of quartz have the sizes from 80 up to 500 μm. Between quartz crystals the sericite inclusions having a tablet form with radiant structure are located. The size of sericite crystals is ~ 40-250 μm. Using data on interplanar distance [6,7] and ASTM Powder X-ray Diffraction Data it is shown that natural «a porcelain stone» quartz – sericite consists the quartz SiO2, sericite (muscovite type) KAl2[AlSi3O10](OH)2 and kaolinite Al203SiO22Н2О (See Figure 2 and Table 2). As it seen in the figure 3 and table 3a after annealing at 900oC the quartz – sericite contains quartz – SiO2 and muscovite - KAl2[AlSi3O10](OH)2, the peaks related with Kaolinite are absent. After annealing at 1120oC the full disintegration of muscovite and formation of mullite phase Al203 SiO2 is observed (the weak peaks of mullite appears in fig 3b and table 3b). After annealing at 1350oC the samples contains crystal phase of quartz and mullite (figure 3c and table 3с). Well known Mullite gives to ceramics high density, abrasive and chemical stability. Thus the obtained experimental data on formation of various phases during thermal annealing can be used for development of fabrication technology of advanced materials. Conclusion: The influence of thermal annealing in the interval 900-1350oC on phase composition and structure of quartz-sericite minerale is investigated. It is shown that during annealing the phase content of raw material is changed. After annealing at 1350oC the samples contains crystal phase of quartz and mullite (which gives gives to ceramics high density, abrasive and chemical stability). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quartz-sericite" title="quartz-sericite">quartz-sericite</a>, <a href="https://publications.waset.org/abstracts/search?q=kaolinite" title=" kaolinite"> kaolinite</a>, <a href="https://publications.waset.org/abstracts/search?q=mullite" title=" mullite"> mullite</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20processing" title=" thermal processing"> thermal processing</a> </p> <a href="https://publications.waset.org/abstracts/28557/influence-of-thermal-annealing-on-phase-composition-and-structure-of-quartz-sericite-minerale" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28557.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">414</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">6599</span> Assess Changes in Groundwater Dynamics Caused by Mini Dam Construction in Arid Zone of District Killa Abdullah, Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akhtar%20Malik%20Muhammad">Akhtar Malik Muhammad</a>, <a href="https://publications.waset.org/abstracts/search?q=Agha%20Mirwais"> Agha Mirwais</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dams are considered to recharge aquifers by raising the water table, especially the ones near wells. The present study investigates the impact of dams on groundwater recharge in Jilga, Pakistan. The comparative analysis of changes in the groundwater table of the year 2012 and 2019 was carried out using ArcGIS 10.5 through the kriging method and remote sensing techniques to evaluate the mini dam's impact on the upstream area. Arc Info Spatial Analyze extension was used to find static water level maps of the years. The water table was observed minimum 67.08 feet and maximum 130.09 feet in 2012 whereas in 2019 the minimum water table level 49.89 feet and maximum 115.85 feet. Groundwater recharge with different ratio was noted, but the most significant was at Rabbani dam with 26ft due to supported lithology conditions and the lowest recharge was found at Garang dam14ft. The overall positive trend indicates the rehabilitation of dead karez and agriculture activities by increasing 36% the vegetation area in 2019. An over 6% increase in human settlement indicates socioeconomic development. Thus, it highlights the need for preferential focus on the construction of the dam so that the water level could be sustained to cater to the agricultural and domestic needs of the local population around the year <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20table" title="water table">water table</a>, <a href="https://publications.waset.org/abstracts/search?q=GIS" title=" GIS"> GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20cover" title=" land cover"> land cover</a>, <a href="https://publications.waset.org/abstracts/search?q=mini%20dams" title=" mini dams"> mini dams</a>, <a href="https://publications.waset.org/abstracts/search?q=agriculture" title=" agriculture"> agriculture</a> </p> <a href="https://publications.waset.org/abstracts/159460/assess-changes-in-groundwater-dynamics-caused-by-mini-dam-construction-in-arid-zone-of-district-killa-abdullah-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159460.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">84</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">6598</span> Spatial Data Mining by Decision Trees</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sihem%20Oujdi">Sihem Oujdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hafida%20Belbachir"> Hafida Belbachir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Existing methods of data mining cannot be applied on spatial data because they require spatial specificity consideration, as spatial relationships. This paper focuses on the classification with decision trees, which are one of the data mining techniques. We propose an extension of the C4.5 algorithm for spatial data, based on two different approaches Join materialization and Querying on the fly the different tables. Similar works have been done on these two main approaches, the first - Join materialization - favors the processing time in spite of memory space, whereas the second - Querying on the fly different tables- promotes memory space despite of the processing time. The modified C4.5 algorithm requires three entries tables: a target table, a neighbor table, and a spatial index join that contains the possible spatial relationship among the objects in the target table and those in the neighbor table. Thus, the proposed algorithms are applied to a spatial data pattern in the accidentology domain. A comparative study of our approach with other works of classification by spatial decision trees will be detailed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=C4.5%20algorithm" title="C4.5 algorithm">C4.5 algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20trees" title=" decision trees"> decision trees</a>, <a href="https://publications.waset.org/abstracts/search?q=S-CART" title=" S-CART"> S-CART</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20data%20mining" title=" spatial data mining"> spatial data mining</a> </p> <a href="https://publications.waset.org/abstracts/11935/spatial-data-mining-by-decision-trees" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11935.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">612</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">6597</span> Design and Construction of an Intelligent Multiplication Table for Enhanced Education and Increased Student Engagement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Alikhani%20Koopaei">Zahra Alikhani Koopaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the fifth lesson of the third-grade mathematics book, students are introduced to the concept of multiplication. However, some students showed a lack of interest in learning this topic. To address this, a simple electronic multiplication table was designed with the aim of making the concept of multiplication entertaining and engaging for students. It provides them with moments of excitement during the learning process. To achieve this goal, a device was created that produced a bell sound when two wire ends were connected. Each wire end was connected to a specific number in the multiplication table, and the other end was linked to the corresponding answer. Consequently, if the answer is correct, the bell will ring. This study employs interactive and engaging methods to teach mathematics, particularly to students who have previously shown little interest in the subject. By integrating game-based learning and critical thinking, we observed an increase in understanding and interest in learning multiplication compared to before using this method. This further motivated the students. As a result, the intelligent multiplication table was successfully designed. Students, under the instructor's supervision, could easily construct the device during the lesson. Through the implementation of these operations, the concept of multiplication was firmly established in the students' minds. Engaging multiple intelligences in each student enhances a more stable and improved understanding of the concept of multiplication. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=intelligent%20multiplication%20table" title="intelligent multiplication table">intelligent multiplication table</a>, <a href="https://publications.waset.org/abstracts/search?q=design" title=" design"> design</a>, <a href="https://publications.waset.org/abstracts/search?q=construction" title=" construction"> construction</a>, <a href="https://publications.waset.org/abstracts/search?q=education" title=" education"> education</a>, <a href="https://publications.waset.org/abstracts/search?q=increased%20interest" title=" increased interest"> increased interest</a>, <a href="https://publications.waset.org/abstracts/search?q=students" title=" students"> students</a> </p> <a href="https://publications.waset.org/abstracts/176502/design-and-construction-of-an-intelligent-multiplication-table-for-enhanced-education-and-increased-student-engagement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176502.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">68</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">6596</span> Classifying and Analysis 8-Bit to 8-Bit S-Boxes Characteristic Using S-Box Evaluation Characteristic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Luqman">Muhammad Luqman</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Kurniawan"> Yusuf Kurniawan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> S-Boxes is one of the linear parts of the cryptographic algorithm. The existence of S-Box in the cryptographic algorithm is needed to maintain non-linearity of the algorithm. Nowadays, modern cryptographic algorithms use an S-Box as a part of algorithm process. Despite the fact that several cryptographic algorithms today reuse theoretically secure and carefully constructed S-Boxes, there is an evaluation characteristic that can measure security properties of S-Boxes and hence the corresponding primitives. Analysis of an S-Box usually is done using manual mathematics calculation. Several S-Boxes are presented as a Truth Table without any mathematical background algorithm. Then, it’s rather difficult to determine the strength of Truth Table S-Box without a mathematical algorithm. A comprehensive analysis should be applied to the Truth Table S-Box to determine the characteristic. Several important characteristics should be owned by the S-Boxes, they are Nonlinearity, Balancedness, Algebraic degree, LAT, DAT, differential delta uniformity, correlation immunity and global avalanche criterion. Then, a comprehensive tool will be present to automatically calculate the characteristics of S-Boxes and determine the strength of S-Box. Comprehensive analysis is done on a deterministic process to produce a sequence of S-Boxes characteristic and give advice for a better S-Box construction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryptographic%20properties" title="cryptographic properties">cryptographic properties</a>, <a href="https://publications.waset.org/abstracts/search?q=Truth%20Table%20S-Boxes" title=" Truth Table S-Boxes"> Truth Table S-Boxes</a>, <a href="https://publications.waset.org/abstracts/search?q=S-Boxes%20characteristic" title=" S-Boxes characteristic"> S-Boxes characteristic</a>, <a href="https://publications.waset.org/abstracts/search?q=deterministic%20process" title=" deterministic process"> deterministic process</a> </p> <a href="https://publications.waset.org/abstracts/65017/classifying-and-analysis-8-bit-to-8-bit-s-boxes-characteristic-using-s-box-evaluation-characteristic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65017.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">362</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">6595</span> Age-Stage, Two-Sex Life Table Characteristics of Aedes albopictus (Skuse) and Aedes aegypti (Linnaeus)) (Diptera: Culicidae) in Penang Island, Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20H.%20Maimusa">A.

The life expectancy was 19.01 and 19.94 days for Ae. albopictus and Ae. aegypti respectively. Mortality occurred mostly during the adult stage and ranged between 0.01 and 0.07%. The population parameters suggest that Ae. albopictus and Ae. aegypti populations are r-strategist characterized by a high r, a large Ro, and short T. This kind of information is crucial in understanding mosquito population dynamics in disease transmission and control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ae.%20aegypti" title="Ae. aegypti">Ae. aegypti</a>, <a href="https://publications.waset.org/abstracts/search?q=Ae.%20albopictus" title=" Ae. albopictus"> Ae. albopictus</a>, <a href="https://publications.waset.org/abstracts/search?q=age-stage" title=" age-stage"> age-stage</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20table" title=" life table"> life table</a>, <a href="https://publications.waset.org/abstracts/search?q=two-sex" title=" two-sex"> two-sex</a> </p> <a href="https://publications.waset.org/abstracts/31948/age-stage-two-sex-life-table-characteristics-of-aedes-albopictus-skuse-and-aedes-aegypti-linnaeus-diptera-culicidae-in-penang-island-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31948.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">318</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">6594</span> Stable Isotope Ratios Data for Tracing the Origin of Greek Olive Oils and Table Olives</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Efthimios%20Kokkotos">Efthimios Kokkotos</a>, <a href="https://publications.waset.org/abstracts/search?q=Kostakis%20Marios"> Kostakis Marios</a>, <a href="https://publications.waset.org/abstracts/search?q=Beis%20Alexandros"> Beis Alexandros</a>, <a href="https://publications.waset.org/abstracts/search?q=Angelos%20Patakas"> Angelos Patakas</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonios%20Avgeris"> Antonios Avgeris</a>, <a href="https://publications.waset.org/abstracts/search?q=Vassilios%20Triantafyllidis"> Vassilios Triantafyllidis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> H, C, and O stable isotope ratios were measured in different olive oils and table olives originating from different regions of Greece. In particular, the stable isotope ratios of different olive oils produced in the Lakonia region (Peloponesse – South Greece) from different varieties, i.e., cvs ‘Athinolia’ and ‘koroneiki’, were determined. Additionally, stable isotope ratios were also measured in different table olives (cvs ‘koroneiki’ and ‘kalamon’) produced in the same region (Messinia). The aim of this study was to provide sufficient isotope ratio data regarding each variety and region of origin that could be used in discriminative studies of oil olives and table olives produced by different varieties in other regions. In total, 97 samples of olive oil (cv ‘Athinolia’ and ‘koroneiki’) and 67 samples of table olives (cvs ‘kalmon’ and ‘koroneiki’) collected during two consecutive sampling periods (2021-2022 and 2022-2023) were measured. The C, H, and O isotope ratios were measured using Isotope Ratio Mass Spectrometry (IRMS), and the results obtained were analyzed using chemometric techniques. The measurements of the isotope ratio analyses were expressed in permille (‰) using the delta δ notation (δ=Rsample/Rstandard-1, where Rsample and Rstandardis represent the isotope ratio of sample and standard). Results indicate that stable isotope ratios of C, H, and O ranged between -28,5+0,45‰, -142,83+2,82‰, 25,86+0,56‰ and -29,78+0,71‰, -143,62+1,4‰, 26,32+0,55‰ in olive oils produced in Lakonia region from ‘Athinolia’ and ‘koroneiki ‘varieties, respectively. The C, H, and O values from table olives originated from Messinia region were -28,58+0,63‰, -138,09+3,27‰, 25,45+0,62‰ and -29,41+0,59‰,-137,67+1,15‰, 24,37+0,6‰ for ‘Kalamon’ and ‘koroneiki’ olives respectively.

It is contingent on a parsing table, whereas the parsing tables are extracted from the grammar. The parsing table specifies the actions to be taken during parsing. It requires that the parsing table should have no action conflicts for the same input symbol. This requirement imposes a condition on the class of grammars over which the LR algorithms work. However, there are grammars for which the parsing tables hold action conflicts. In such cases, the algorithm needs a capability of scanning (looking-ahead) next input symbols ahead of the current input symbol. In this paper, a ‘Left to Right’-‘Right Most’ parsing algorithm with lookahead capability is introduced. The 'look-ahead' capability in the LR parsing algorithm is the major contribution of this paper. The practicality of the proposed algorithm is substantiated by the parser implementation of the Context Free Grammar (CFG) of an already proposed programming language 'State Controlled Object Oriented Programming' (SCOOP). SCOOP’s Context Free Grammar has 125 productions and 192 item sets. This algorithm parses SCOOP while the grammar requires to ‘look ahead’ the input symbols due to action conflicts in its parsing table. Proposed LR parsing algorithm with lookahead capability can be viewed as an optimization of ‘Simple Left to Right’-‘Right Most’ (SLR) parsing algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=left%20to%20right-right%20most%20parsing" title="left to right-right most parsing">left to right-right most parsing</a>, <a href="https://publications.waset.org/abstracts/search?q=syntax%20analysis" title=" syntax analysis"> syntax analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=bottom-up%20parsing%20algorithm" title=" bottom-up parsing algorithm"> bottom-up parsing algorithm</a> </p> <a href="https://publications.waset.org/abstracts/128733/left-to-right-right-most-parsing-algorithm-with-lookahead" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128733.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">126</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">6592</span> Sublethal Effects of Thiamethoxam-Lambda Cyhalothrin on the Life Table Parameters and Population Projection of Trialeurodes vaporariorum (Hemiptera: Aleyrodidae) and Its Parasitoid, Encarsia formosa (Hymenoptera: Aphelinidae)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sevda%20Ddras">Sevda Ddras</a>, <a href="https://publications.waset.org/abstracts/search?q=Fariba%20Mehrkhou"> Fariba Mehrkhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Remzi%20Atlihan"> Remzi Atlihan</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Fourouzan"> Maryam Fourouzan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The greenhouse whitefly, Trialeurodes vaporariorum Westwood (Hemiptera: Aleyrodidae), is one of the most important pest on vegetables and ornamental host plants. In this research, the sub-lethal concentration (LC30) of thiamethoxam-lambda cyhalothrin (TLC) on the biological properties, life table parameters and population projection of T. vaporarium and its parasitoid, Encarsia formosa Gahan, were studied at controlled condition (25 ±5 ℃, R.H. 60 ±10 % and a photoperiod of 16:8 h (L:D). Bioassays were conducted by dipping tomato leaves containing third instar nymphs of the whitefly T. vaporariorum, in the obtained LC30 concentration of eforia. The life table data were analyzed using the computer program TWOSEX–MSChart based on the age-stage, two-sex life table theory. The results showed that, usage of sublethal concentration of TLC effected the biological properties and population growth parameters of greenhouse whitefly by shortening the developmentl time, adult longevity, decreasing the fecundity and population growth paramters. Also, the LC30 concentration of TLC had negative effects on life history and life table parameters of E.formosa. The obtained results illustrated that the sublethal concentration of TLC resulted in prolonging of developmental time, decreasing of adult longevity, survival rate and population growth parameters of E.formosa. Additionally, the population projection results were accordance with the population growth rate of either greenhouse whitefly or E.formosa. We conclude that, TLC should not be used in integrated pest management programs where E. formosa exists. <p class="card-text"><strong>Keywords:</strong> <a
