No matter for school music education, professional music education or social music education, the teaching quality is the most important evaluation index. Regarding the research on teaching quality evaluation, scholars at home and abroad have contributed a lot of research results on the basis of multiple methods and evaluation subjects. However, to our best knowledge the complete evaluation model for the virtual teaching interaction mode of the emerging network music education Application (APP) has not been established. This research firstly found out the basic dimensions that accord with the teaching quality required by the three parties, constructing the quality evaluation index system; and then, on the basis of expounding the connotation of each index, it determined the weight of each index by using method of fuzzy analytic hierarchy process, providing ideas and methods for scientific, objective and comprehensive evaluation of the teaching quality of network education APP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=network%20music%20education%20APP" title="network music education APP">network music education APP</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching%20quality%0D%0Aevaluation" title=" teaching quality evaluation"> teaching quality evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=index%20and%20connotation" title=" index and connotation"> index and connotation</a> </p> <a href="https://publications.waset.org/abstracts/131891/research-on-the-teaching-quality-evaluation-of-chinas-network-music-education-app" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131891.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">128</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">3618</span> A Morphological Analysis of Swardspeak in the Philippines </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlo%20Gadingan">Carlo Gadingan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Swardspeak, as a language, highlights the exclusive identity of the Filipino gay men and the oppression they are confronted in the society. This paper presents a morphological analysis of swardspeak in the Philippines. Specifically, it aims to find out the common morphological processes involved in the construction of codes that may unmask the nature of swardspeak as a language. 30 purposively selected expert users of swardspeak from Luzon, Visayas, and Mindanao were asked to codify 30 natural words through the Facebook Messenger application. The results of the structural analysis affirm that swardspeak follows no specific rules revealing complicated combinations of clipping/stylized clipping, borrowing, connotation through images, connotation through actions, connotation through sounds, affixation, repetition, substitution, and simple reversal. Moreover, it was also found out that most of these word formation processes occur in all word classes which indicate that swardspeak is very unpredictable. Although different codes are used for the same words, there are still codes that are really common to all homosexuals and these are Chaka (ugly), Crayola (cry), and Aida (referring to a person with AIDS). Hence, the prevailing word formation processes explored may be termed as observed time-specific patterns because the codes documented in this study may turn obsolete and may be replaced with novel ones in a matter of weeks to month, knowing the creativity of homosexuals and the multiplicity of societal resources which can be used to make the codes more opaque and more confusing for non-homosexuals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=codes" title="codes">codes</a>, <a href="https://publications.waset.org/abstracts/search?q=homosexuals" title=" homosexuals"> homosexuals</a>, <a href="https://publications.waset.org/abstracts/search?q=morphological%20processes" title=" morphological processes"> morphological processes</a>, <a href="https://publications.waset.org/abstracts/search?q=swardspeak" title=" swardspeak"> swardspeak</a> </p> <a href="https://publications.waset.org/abstracts/92706/a-morphological-analysis-of-swardspeak-in-the-philippines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92706.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">179</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">3617</span> Topological Indices of Some Graph Operations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=U.%20Mary">U.

This study finds four translation phenomena among the street signs: domestication with positive connotation, foreignization with negative connotation, bilingual incompatibilities, and cross-street complexities. The interplay of, and the tension between, the four features open up a space where the local and the foreign, the vulgar and the elegant, alternate and experiment with each other, creating a kaleidoscope of methods for expressing and domesticating foreign otherness by virtue of translation. An analysis of the phenomena from the functional perspective reveals how translation has been emancipated to inform a variety of dimensions. This study also renews our understanding of translation as both a concept and a practice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=street%20signs" title="street signs">street signs</a>, <a href="https://publications.waset.org/abstracts/search?q=linguistic%20landscape" title=" linguistic landscape"> linguistic landscape</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20hybridity" title=" cultural hybridity"> cultural hybridity</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Kong" title=" Hong Kong"> Hong Kong</a> </p> <a href="https://publications.waset.org/abstracts/120581/conflicts-and-complexities-a-study-of-hong-kongs-bilingual-street-signs-from-functional-perspective-on-translation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120581.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">211</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">3615</span> Sustainability Enhancement of Pedestrian Space Quality in Old Communities from the Perspective of Inclusiveness:Taking Cao Yang New Village, Shanghai as an Example</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Feng%20Zisu">Feng Zisu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Community is the basic unit of the city, community pedestrian space is also an important part of the urban public space, and its quality improvement is also closely related to the residents' happiness and sense of belonging. Domestic and international research perspectives on community pedestrian space have gradually changed to inclusive design for the whole population, paying more attention to the equitable accessibility of urban space and the multiple composite enhancement of spatial connotation. In order to realize the inclusive and sustainable development of pedestrian space in old communities, this article selects Cao Yang New Village in Shanghai as a practice case, and based on the connotation of inclusiveness, the four dimensions of space, traffic, function and emotion are selected as the layers of inclusive connotation of pedestrian space in old communities. This article identifies the objective social needs, dynamic activity characteristics and subjective feelings of multiple subjects, and reconstructs the structural hierarchy of “spatial perception - behavioral characteristics - subjective feelings” of walking. It also proposes a governance strategy of “reconfiguring the pedestrian network, optimizing street quality, integrating ecological space and reshaping the community scene” from the aspects of quality of physical environment and quality of behavioral perception, aiming to provide new ideas for promoting the inclusive and sustainable development of pedestrian space in old communities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inclusivity" title="inclusivity">inclusivity</a>, <a href="https://publications.waset.org/abstracts/search?q=old%20community" title=" old community"> old community</a>, <a href="https://publications.waset.org/abstracts/search?q=pedestrian%20space" title=" pedestrian space"> pedestrian space</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20quality" title=" spatial quality"> spatial quality</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20renovation" title=" sustainable renovation"> sustainable renovation</a> </p> <a href="https://publications.waset.org/abstracts/187390/sustainability-enhancement-of-pedestrian-space-quality-in-old-communities-from-the-perspective-of-inclusivenesstaking-cao-yang-new-village-shanghai-as-an-example" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187390.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">35</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">3614</span> A Comparative Study of Multi-SOM Algorithms for Determining the Optimal Number of Clusters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Im%C3%A8n%20Khanchouch">Imèn Khanchouch</a>, <a href="https://publications.waset.org/abstracts/search?q=Malika%20Charrad"> Malika Charrad</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Limam"> Mohamed Limam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The interpretation of the quality of clusters and the determination of the optimal number of clusters is still a crucial problem in clustering.

For that purpose, this paper evaluates the difference of the H-index from those services. Researchers indexed by Webometrics, are used as reference’s data in this paper. Currently, Webometrics only uses H-index from Google Scholar. This paper observed and compared corresponding researchers’ data from Scopus to get their H-index score. Subsequently, some researchers with huge differences in score are observed in more detail on their paper’s publisher. This paper shows that the H-index of researchers in Google Scholar is approximately 2.45 times of their Scopus H-Index.

Among the requirements of such energy efficiency index, the practical feasibility must be essential. To illustrate the performance of the proposed index, such an index was used as decisive factor of evaluation for the optimization process of an industrial reactor. The results allow the conclusion to be drawn that the energy efficiency index applied to the reactive system is consistent because it extracts the information expected of an efficient indicator, and that it is useful as an analytical tool besides being feasible from a practical standpoint. Furthermore, it has proved to be much simpler to use than tools based on traditional methodologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy" title="energy">energy</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=entropy" title=" entropy"> entropy</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive" title=" reactive"> reactive</a> </p> <a href="https://publications.waset.org/abstracts/45768/energy-efficiency-index-applied-to-reactive-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45768.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">411</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">3610</span> An Efficiency Measurement of E-Government Performance for United Nation Ranking Index</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yassine%20Jadi">Yassine Jadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Lin%20Jie"> Lin Jie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to serve the society in an electronic manner, many developing countries have launched tremendous e-government projects.

The EEG signal recording was conducted on 51 healthy subjects. Development of 3D EEG models involves pre-processing of raw EEG signals and construction of spectrogram images. Then, maximum PSD values were extracted as features from the model. There are three indexes for the balanced brain; index 3, index 4 and index 5. There are significant different of the EEG signals due to the brain balancing index (BBI). Alpha-α (8–13 Hz) and beta-β (13–30 Hz) were used as input signals for the classification model. The k-NN classification result is 88.46% accuracy. These results proved that k-NN can be used in order to predict the brain balancing application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=power%20spectral%20density" title="power spectral density">power spectral density</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20EEG%20model" title=" 3D EEG model"> 3D EEG model</a>, <a href="https://publications.waset.org/abstracts/search?q=brain%20balancing" title=" brain balancing"> brain balancing</a>, <a href="https://publications.waset.org/abstracts/search?q=kNN" title=" kNN"> kNN</a> </p> <a href="https://publications.waset.org/abstracts/11285/brainwave-classification-for-brain-balancing-index-bbi-via-3d-eeg-model-using-k-nn-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11285.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">487</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">3607</span> Quality of Age Reporting from Tanzania 2012 Census Results: An Assessment Using Whipple’s Index, Myer’s Blended Index, and Age-Sex Accuracy Index</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Sathiya%20Susuman">A.

However, a variety of irregularities and misstatement are noted with respect to age-related data and less to sex data because of its biological differences between the genders. Noting the misstatement/misreporting of age data regardless of its significance importance in demographics and epidemiological studies, this study aims at assessing the quality of 2012 Tanzania Population and Housing Census Results. Methods: Data for the analysis are downloaded from Tanzania National Bureau of Statistics. Age heaping and digit preference were measured using summary indices viz., Whipple’s index, Myers’ blended index, and Age-Sex Accuracy index. Results: The recorded Whipple’s index for both sexes was 154.43; male has the lowest index of about 152.65 while female has the highest index of about 156.07. For Myers’ blended index, the preferences were at digits ‘0’ and ‘5’ while avoidance were at digits ‘1’ and ‘3’ for both sexes. Finally, Age-sex index stood at 59.8 where sex ratio score was 5.82 and age ratio scores were 20.89 and 21.4 for males and female respectively. Conclusion: The evaluation of the 2012 PHC data using the demographic techniques has qualified the data inaccurate as the results of systematic heaping and digit preferences/avoidances. Thus, innovative methods in data collection along with measuring and minimizing errors using statistical techniques should be used to ensure accuracy of age data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=age%20heaping" title="age heaping">age heaping</a>, <a href="https://publications.waset.org/abstracts/search?q=digit%20preference%2Favoidance" title=" digit preference/avoidance"> digit preference/avoidance</a>, <a href="https://publications.waset.org/abstracts/search?q=summary%20indices" title=" summary indices"> summary indices</a>, <a href="https://publications.waset.org/abstracts/search?q=Whipple%E2%80%99s%20index" title=" Whipple’s index"> Whipple’s index</a>, <a href="https://publications.waset.org/abstracts/search?q=Myer%E2%80%99s%20index" title=" Myer’s index"> Myer’s index</a>, <a href="https://publications.waset.org/abstracts/search?q=age-sex%20accuracy%20index" title=" age-sex accuracy index"> age-sex accuracy index</a> </p> <a href="https://publications.waset.org/abstracts/25823/quality-of-age-reporting-from-tanzania-2012-census-results-an-assessment-using-whipples-index-myers-blended-index-and-age-sex-accuracy-index" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25823.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">476</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">3606</span> Affective Transparency in Compound Word Processing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jordan%20Gallant">Jordan Gallant</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the compound word processing literature, much attention has been paid to the relationship between a compound’s denotational meaning and that of its morphological whole-word constituents, which is referred to as ‘semantic transparency’. However, the parallel relationship between a compound’s connotation and that of its constituents has not been addressed at all. For instance, while a compound like ‘painkiller’ might be semantically transparent, it is not ‘affectively transparent’. That is, both constituents have primarily negative connotations, while the whole compound has a positive one. This paper investigates the role of affective transparency on compound processing using two methodologies commonly employed in this field: a lexical decision task and a typing task. The critical stimuli used were 112 English bi-constituent compounds that differed in terms of the effective transparency of their constituents. Of these, 36 stimuli contained constituents with similar connotations to the compound (e.g., ‘dreamland’), 36 contained constituents with more positive connotations (e.g. ‘bedpan’), and 36 contained constituents with more negative connotations (e.g. ‘painkiller’). Connotation of whole-word constituents and compounds were operationalized via valence ratings taken from an off-line ratings database. In Experiment 1, compound stimuli and matched non-word controls were presented visually to participants, who were then asked to indicate whether it was a real word in English. Response times and accuracy were recorded. In Experiment 2, participants typed compound stimuli presented to them visually. Individual keystroke response times and typing accuracy were recorded. The results of both experiments provided positive evidence that compound processing is influenced by effective transparency. In Experiment 1, compounds in which both constituents had more negative connotations than the compound itself were responded to significantly more slowly than compounds in which the constituents had similar or more positive connotations. Typed responses from Experiment 2 showed that inter-keystroke intervals at the morphological constituent boundary were significantly longer when the connotation of the head constituent was either more positive or more negative than that of the compound. The interpretation of this finding is discussed in the context of previous compound typing research. Taken together, these findings suggest that affective transparency plays a role in the recognition, storage, and production of English compound words. This study provides a promising first step in a new direction for research on compound words. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compound%20processing" title="compound processing">compound processing</a>, <a href="https://publications.waset.org/abstracts/search?q=semantic%20transparency" title=" semantic transparency"> semantic transparency</a>, <a href="https://publications.waset.org/abstracts/search?q=typed%20production" title=" typed production"> typed production</a>, <a href="https://publications.waset.org/abstracts/search?q=valence" title=" valence"> valence</a> </p> <a href="https://publications.waset.org/abstracts/134522/affective-transparency-in-compound-word-processing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134522.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">127</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">3605</span> The Research of Weights Identify of Harbin Ecological Security Evaluation Index Based on AHP</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rong%20Guo">Rong Guo</a>, <a href="https://publications.waset.org/abstracts/search?q=Mengshi%20Huang"> Mengshi Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yujing%20Bai"> Yujing Bai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the rapid development of urbanization, the urban population increases and urban sprawl appeared.

Furthermore, we introduce a new quantitative method for estimating the headcount index. In particular, we suggest to use the logistic regression estimator for the problem of estimating the headcount index. Assuming a real data set, results derived from Monte Carlo simulation studies indicate that the logistic regression estimator can be more accurate than the traditional estimator of the headcount index. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=poverty%20line" title="poverty line">poverty line</a>, <a href="https://publications.waset.org/abstracts/search?q=poor" title=" poor"> poor</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20of%20poverty" title=" risk of poverty"> risk of poverty</a>, <a href="https://publications.waset.org/abstracts/search?q=Monte%20Carlo%20simulations" title=" Monte Carlo simulations"> Monte Carlo simulations</a>, <a href="https://publications.waset.org/abstracts/search?q=sample" title=" sample"> sample</a> </p> <a href="https://publications.waset.org/abstracts/7876/on-estimating-the-headcount-index-by-using-the-logistic-regression-estimator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7876.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">423</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">3603</span> Compression Index Estimation by Water Content and Liquid Limit and Void Ratio Using Statistics Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lizhou%20Chen">Lizhou Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelhamid%20Belgaid"> Abdelhamid Belgaid</a>, <a href="https://publications.waset.org/abstracts/search?q=Assem%20Elsayed"> Assem Elsayed</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaoming%20Yang"> Xiaoming Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Compression index is essential in foundation settlement calculation. The traditional method for determining compression index is consolidation test which is expensive and time consuming. Many researchers have used regression methods to develop empirical equations for predicting compression index from soil properties. Based on a large number of compression index data collected from consolidation tests, the accuracy of some popularly empirical equations were assessed. It was found that primary compression index is significantly overestimated in some equations while it is underestimated in others. The sensitivity analyses of soil parameters including water content, liquid limit and void ratio were performed. The results indicate that the compression index obtained from void ratio is most accurate. The ANOVA (analysis of variance) demonstrates that the equations with multiple soil parameters cannot provide better predictions than the equations with single soil parameter. In other words, it is not necessary to develop the relationships between compression index and multiple soil parameters. Meanwhile, it was noted that secondary compression index is approximately 0.7-5.0% of primary compression index with an average of 2.0%. In the end, the proposed prediction equations using power regression technique were provided that can provide more accurate predictions than those from existing equations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compression%20index" title="compression index">compression index</a>, <a href="https://publications.waset.org/abstracts/search?q=clay" title=" clay"> clay</a>, <a href="https://publications.waset.org/abstracts/search?q=settlement" title=" settlement"> settlement</a>, <a href="https://publications.waset.org/abstracts/search?q=consolidation" title=" consolidation"> consolidation</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20compression%20index" title=" secondary compression index"> secondary compression index</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20parameter" title=" soil parameter"> soil parameter</a> </p> <a href="https://publications.waset.org/abstracts/111582/compression-index-estimation-by-water-content-and-liquid-limit-and-void-ratio-using-statistics-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111582.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">163</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">3602</span> The Threshold Values of Soil Water Index for Landslides on Country Road No.89</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ji-Yuan%20Lin">Ji-Yuan Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Ming%20Liou"> Yu-Ming Liou</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Ting%20Chen"> Yi-Ting Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Chen-Syuan%20Lin"> Chen-Syuan Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Soil water index obtained by tank model is now commonly used in soil and sand disaster alarm system in Japan.

However, in fact, the key factors affecting the development of the blue economy have not been explored in depth, and the development policies and performance of the blue economy have not been scientifically evaluated. This cannot provide useful guidance for the development of the blue economy. Therefore, it is urgent to establish a quantitative evaluation framework to measure the performance of the blue economic development.

The new spectral index was tested on different areas of World-View 2 images and the results demonstrated that the new spectral index has a massive potential to extract shadows effectively and automatically. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spectral%20index" title="spectral index">spectral index</a>, <a href="https://publications.waset.org/abstracts/search?q=shadow%20detection" title=" shadow detection"> shadow detection</a>, <a href="https://publications.waset.org/abstracts/search?q=remote%20sensing%20images" title=" remote sensing images"> remote sensing images</a>, <a href="https://publications.waset.org/abstracts/search?q=World-View%202" title=" World-View 2"> World-View 2</a> </p> <a href="https://publications.waset.org/abstracts/13500/a-novel-spectral-index-for-automatic-shadow-detection-in-urban-mapping-based-on-worldview-2-satellite-imagery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13500.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">538</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">3599</span> The Assessment of the Comparative Efficiency of Reforms through the Integral Index of Transformation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samson%20Davoyan">Samson Davoyan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashot%20Davoyan"> Ashot Davoyan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ani%20Khachatryan"> Ani Khachatryan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The indexes (Global Competitiveness Index, Economic Freedom Index, Human Development Index, etc.) developed by different international and non-government organizations in time and space express the quantitative and qualitative features of different fields of various reforms implemented in different countries. The main objective of our research is to develop new methodology that we will use to create integral index based on many indexes and that will include many areas of reforms. To achieve our aim we have used econometric methods (regression model for panel data method). The basis of our methodology is the development of the new integral index based on quantitative assessment of the change of two main parameters: the score of the countries by different indexes and the change of the ranks of countries for following two periods of time. As a result of the usage of methods for analyzes we have defined the indexes that are used to create the new integral index and the scales for each of them. Analyzing quantitatively and qualitatively analysis through the integral index for more than 100 countries for 2009-2014, we have defined comparative efficiency that helps to conclude in which directions countries have implemented reforms more effectively compared to others and in which direction reforms have implemented less efficiently. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=development" title="development">development</a>, <a href="https://publications.waset.org/abstracts/search?q=rank" title=" rank"> rank</a>, <a href="https://publications.waset.org/abstracts/search?q=reforms" title=" reforms"> reforms</a>, <a href="https://publications.waset.org/abstracts/search?q=comparative" title=" comparative"> comparative</a>, <a href="https://publications.waset.org/abstracts/search?q=index" title=" index"> index</a>, <a href="https://publications.waset.org/abstracts/search?q=economic" title=" economic"> economic</a>, <a href="https://publications.waset.org/abstracts/search?q=corruption" title=" corruption"> corruption</a>, <a href="https://publications.waset.org/abstracts/search?q=social" title=" social"> social</a>, <a href="https://publications.waset.org/abstracts/search?q=program" title=" program"> program</a> </p> <a href="https://publications.waset.org/abstracts/29322/the-assessment-of-the-comparative-efficiency-of-reforms-through-the-integral-index-of-transformation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29322.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">326</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">3598</span> Sustainability Index for REDD-Plus Implementation in Central Kalimantan, Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Febrina%20Natalia">Febrina Natalia</a>, <a href="https://publications.waset.org/abstracts/search?q=Noriyuki%20Tanaka"> Noriyuki Tanaka</a>, <a href="https://publications.waset.org/abstracts/search?q=Mitsuru%20Osaki"> Mitsuru Osaki </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sustainability Index for REDD-plus implementation was constructed to evaluate the sustainability of different communities in 5 villages (Taruna Jaya, Tumbang Nusa, Marang, Terantang, and Seragam Jaya) in Central Kalimantan, Indonesia based on the main objectives of REDD-plus project (reducing emission from deforestation and forest degradation, increasing carbon stock, preserving biodiversity and sustaining forest management). This index was separately composed of 3 different components; (1) ecology, (2) economy, and (3) society. The index of sustainability was determined into four categories; 3,3-4,0 (excellent), 2,5-3,2 (good), 1,8-2,4 (fair), and 1,0-1,7 (poor).

The time to collision (TTC) and time headway (TH) are used to evaluate the TTC forward collision probability index (TFCPI) and the TH forward collision probability index (HFCPI), respectively. The Mamdani fuzzy inference algorithm is presented combining TFCPI and HFCPI to calculate the approaching collision probability index of the vehicle. The AFCPI is easier to understand for the driver who did not even have any professional knowledge in vehicle professional field. At the same time, the driver’s behavior is taken into account for suiting each driver. For the approaching index, the value 0 is indicating the 0% probability of forward collision, and the values 0.5 and 1 are indicating the 50% and 100% probabilities of forward collision, respectively. The AFCPI is useful and easy-to-understand for alerting driver to avoid the forward collision accidents when driving in highway. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=approaching%20index" title="approaching index">approaching index</a>, <a href="https://publications.waset.org/abstracts/search?q=forward%20collision%20probability" title=" forward collision probability"> forward collision probability</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20to%20collision" title=" time to collision"> time to collision</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20headway" title=" time headway"> time headway</a> </p> <a href="https://publications.waset.org/abstracts/74855/an-approaching-index-to-evaluate-a-forward-collision-probability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74855.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">293</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">3594</span> A High-Resolution Refractive Index Sensor Based on a Magnetic Photonic Crystal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ti-An%20Tsai">Ti-An Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=Chun-Chih%20Wang"> Chun-Chih Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hung-Wen%20Wang"> Hung-Wen Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=I-Ling%20Chang"> I-Ling Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Lien-Wen%20Chen"> Lien-Wen Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, we demonstrate a high-resolution refractive index sensor based on a magnetic photonic crystal (MPC) composed of a triangular lattice array of air holes embedded in Si matrix. A microcavity is created by changing the radius of an air hole in the middle of the photonic crystal. The cavity filled with gyrotropic materials can serve as a refractive index sensor. The shift of the resonant frequency of the sensor is obtained numerically using finite difference time domain method under different ambient conditions having refractive index from n = 1.0 to n = 1.1. The numerical results show that a tiny change in refractive index of Δn = 0.0001 is distinguishable. In addition, the spectral response of the MPC sensor is studied while an external magnetic field is present. The results show that the MPC sensor exhibits a dramatic improvement in resolution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnetic%20photonic%20crystal" title="magnetic photonic crystal">magnetic photonic crystal</a>, <a href="https://publications.waset.org/abstracts/search?q=refractive%20index%20sensor" title=" refractive index sensor"> refractive index sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity" title=" sensitivity"> sensitivity</a>, <a href="https://publications.waset.org/abstracts/search?q=high-resolution" title=" high-resolution"> high-resolution</a> </p> <a href="https://publications.waset.org/abstracts/26102/a-high-resolution-refractive-index-sensor-based-on-a-magnetic-photonic-crystal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26102.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">591</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">3593</span> A New Prediction Model for Soil Compression Index </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20Mohammadzadeh%20S.">D.

Iran's exports of crude oil and lease condensate reduced to roughly 1.5 million barrels per day (bbl/d) in 2012, compared to 2.5 million bbl/d in 2011 due to hard sanctions. Monthly data are collected and subjected to a battery of tests through ordinary least square by EViews7. This study found that gold price and oil price are positively correlated with stock returns while total oil supplied and consumer price index have negative relationship with stock index, however, consumer price index tends to become insignificant in stock index. While gold price and consumer price index have short run relationship with TSE index at 10% of significance level this amount for oil price is significant at 5% and there is no significant short run relationship between supplied oil and Tehran stock returns. Moreover, this study found that all macroeconomic factors have long-run relationship with Tehran Stock Exchange Index. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=consumer%20price%20index" title="consumer price index">consumer price index</a>, <a href="https://publications.waset.org/abstracts/search?q=gold%20price" title=" gold price"> gold price</a>, <a href="https://publications.waset.org/abstracts/search?q=macroeconomic" title=" macroeconomic"> macroeconomic</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20price" title=" oil price"> oil price</a>, <a href="https://publications.waset.org/abstracts/search?q=sanction" title=" sanction"> sanction</a>, <a href="https://publications.waset.org/abstracts/search?q=stock%20market" title=" stock market"> stock market</a>, <a href="https://publications.waset.org/abstracts/search?q=supplied%20oil" title=" supplied oil"> supplied oil</a> </p> <a href="https://publications.waset.org/abstracts/3992/the-impact-of-macroeconomic-factors-on-tehran-stock-exchange-index-during-economic-and-oil-sanctions-between-january-2006-and-december-2012" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3992.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">489</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3591</span> The Effect of Patient Positioning on Pleth Variability Index during Surgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omid%20Azimaraghi">Omid Azimaraghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Noushin%20Khazaei"> Noushin Khazaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Fluid therapy is an important aspect of the perioperative period and a major challenge for anesthesiologists. To authors best knowledge, there is a lack of strong guidance and evidence regarding the optimal approach to fluid therapy. Therefore a variety of medical devices have been introduced to help physicians. In this study, we aimed to evaluate the effectiveness of pleth variability index in guiding fluid therapy in different patient positions. Materials and Methods: Inclusion criteria consisted of patients aged 18-50 years old and classified as American Society of Anesthesiologists physical status I and II, who were candidates for elective thyroidectomy surgery. In total, 36 patients meeting the inclusion criteria were enrolled in the study. After induction of anesthesia and start of mechanical ventilation Pleth variability index was measured in the supine position, then patients were placed in Trendelenburg and reverse Trendelenburg position (30 degrees, 5 minutes); Pleth Variability Index has measured again in the mentioned positions. Results: Mean PVI (Pleth Variability Index) in the supine position was 14.3 ± 3.7 in comparison to 21.5 ± 4.3 in the reverse Trendelenburg position. The mean PVI in Trendelenburg position was 9.1 ± 2.0 in Trendelenburg position (p < 0.05). Conclusion: In conclusion, we found that Pleth Variability Index varies with patient position and this should be taken into account when using this index during fluid therapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fluid%20therapy" title="fluid therapy">fluid therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=Pleth%20Variability%20Index" title=" Pleth Variability Index"> Pleth Variability Index</a>, <a href="https://publications.waset.org/abstracts/search?q=position" title=" position"> position</a>, <a href="https://publications.waset.org/abstracts/search?q=surgery" title=" surgery"> surgery</a> </p> <a href="https://publications.waset.org/abstracts/94065/the-effect-of-patient-positioning-on-pleth-variability-index-during-surgery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94065.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">166</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">3590</span> Refractometric Optical Sensing by Using Photonics Mach–Zehnder Interferometer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gong%20Zhang">Gong Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Cai"> Hong Cai</a>, <a href="https://publications.waset.org/abstracts/search?q=Bin%20Dong"> Bin Dong</a>, <a href="https://publications.waset.org/abstracts/search?q=Jifang%20Tao"> Jifang Tao</a>, <a href="https://publications.waset.org/abstracts/search?q=Aiqun%20Liu"> Aiqun Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Dim-Lee%20Kwong"> Dim-Lee Kwong</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuandong%20Gu"> Yuandong Gu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An on-chip refractive index sensor with high sensitivity and large measurement range is demonstrated in this paper. The sensing structures are based on Mach-Zehnder interferometer configuration, built on the SOI substrate. The wavelength sensitivity of the sensor is estimated to be 3129 nm/RIU. Meanwhile, according to the interference pattern period changes, the measured period sensitivities are 2.9 nm/RIU (TE mode) and 4.21 nm/RIU (TM mode), respectively. As such, the wavelength shift and the period shift can be used for fine index change detection and larger index change detection, respectively. Therefore, the sensor design provides an approach for large index change measurement with high sensitivity. <p class="card-text"><strong>Keywords:</strong> <a
