She is also a translator that publishes her self-translation The Rice Sprout Song. The purpose of the study is to identify the style of Eileen Chang’s self-translations by corpora, especially in the case of The Rice Sprout Song. The Rice Sprout Song is first written in English and then translated into Chinese by the author herself. The procedure of translation is complicated due to the bilingual transition by the same person. Therefore, the aim of the study is to identify Eileen Chang’s style on her self-translation by comparing her works The Old Man and the Sea, The Rice Sprout Song, and The Rouge of The North. The study uses computer-aided software like AntConc, Notepad++, StanfordCoreNLP, and Python to analyze the style of the works, especially focuses on reduplications and the composition of the sentences. Reduplications are commonly seen in Eileen Chang’s works, and they often appear with colors or onomatopoeia. With these criteria, the style of self-translating can be detected and analyzed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corpora" title="corpora">corpora</a>, <a href="https://publications.waset.org/abstracts/search?q=Eileen%20Chang" title=" Eileen Chang"> Eileen Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=reduplications" title=" reduplications"> reduplications</a>, <a href="https://publications.waset.org/abstracts/search?q=self-translation" title=" self-translation"> self-translation</a> </p> <a href="https://publications.waset.org/abstracts/98317/a-corpus-based-study-of-eileen-changs-self-translating-style-a-case-study-on-the-rice-sprout-song" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98317.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">243</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">639</span> H∞ Sampled-Data Control for Linear Systems Time-Varying Delays: Application to Power System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chang-Ho%20Lee">Chang-Ho Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung-Hoon%20Lee"> Seung-Hoon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Myeong-Jin%20Park"> Myeong-Jin Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Oh-Min%20Kwon"> Oh-Min Kwon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates improved stability criteria for sampled-data control of linear systems with disturbances and time-varying delays.

Compared to earlier dry adhesives, the recently developed ones exhibit excellent adhesion strength, smart directional adhesion, and structural robustness. With these unique adhesion properties, bio-inspired dry adhesive pads have strong potential for use in precision industries such as semiconductor or display manufacturing. In this communication, we present a new manufacturing technology based on advanced dry adhesive systems that enable precise manipulation of large-area substrates over repeating cycles without any requirement for external force application. This new manufacturing technique is also highly accurate and environment-friendly, and thus has strong potential as a next-generation clean manufacturing technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gecko" title="gecko">gecko</a>, <a href="https://publications.waset.org/abstracts/search?q=manufacturing%20robot" title=" manufacturing robot"> manufacturing robot</a>, <a href="https://publications.waset.org/abstracts/search?q=precision%20manufacturing" title=" precision manufacturing"> precision manufacturing</a> </p> <a href="https://publications.waset.org/abstracts/38058/biomimetic-adhesive-pads-for-precision-manufacturing-robots" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38058.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">505</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">635</span> Research for Hollow Reinforced Concrete Bridge Piers in Korea</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ho%20Young%20Kim">Ho Young Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae%20Hoon%20Lee"> Jae Hoon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Do%20Kyu%20Hwang"> Do Kyu Hwang</a>, <a href="https://publications.waset.org/abstracts/search?q=Im%20Jong%20Kwahk"> Im Jong Kwahk</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae%20Hoon%20Kim"> Tae Hoon Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung%20Hoon%20Lee"> Seung Hoon Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hollow section for bridge columns has some advantages.

ECV is used in external variable displacement swash plate type compressor and controls the entire air conditioning system by means of a pulse width modulation (PWM) input signal supplying from an external source (controller). Complete form of ECV contains number of internal features like valve body, core, valve guide, plunger, guide pin, plunger spring, bellows etc. While designing the ECV; dimensions of different internal items must meet the standard requirements as it is quite challenging.

However, since the shear strengths are significantly affected by various factors such as tensile strength of concrete, shear span to depth ratio, volume ratio of steel fiber, and steel fiber factor, the accurate estimations of their shear strengths are very challenging. In this study, therefore, the Adaptive Neuro-Fuzzy System (ANFIS), which has been widely used to solve many complex problems in engineering fields, was introduced to estimate the shear strengths of UHPC flexural members. A total of 32 experimental results has been collected from previous studies for training of the ANFIS algorithm, and the well-trained ANFIS algorithm provided good estimations on the shear strengths of the UHPC test specimens.

However, the measured irradiance data on tilted surfaces are rarely available since installing pyranometers with various tilt angles induces high costs. Therefore, estimating solar irradiance on tilted surfaces is an important research topic. In this work, artificial neural networks (ANN) are utilized to construct the transfer model to estimate solar irradiance on tilted surfaces. Instead of predicting tilted irradiance directly, the proposed method estimates the differences between the horizontal irradiance and the irradiance on a tilted surface. The outputs of the ANNs in the proposed design are differential values. The experimental results have shown that the proposed ANNs with differential outputs can substantially improve the estimation accuracy compared to ANNs that estimate the titled irradiance directly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photovoltaics" title="photovoltaics">photovoltaics</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20networks" title=" artificial neural networks"> artificial neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=tilted%20irradiance" title=" tilted irradiance"> tilted irradiance</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title=" solar energy"> solar energy</a> </p> <a href="https://publications.waset.org/abstracts/99855/estimating-solar-irradiance-on-a-tilted-surface-using-artificial-neural-networks-with-differential-outputs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99855.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">397</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">629</span> Nanoenergetic Materials as Effective Heat Energy Sources for Enhanced Gas Generators</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sang%20Beom%20Kim">Sang Beom Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyung%20Ju%20Kim"> Kyung Ju Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Myung%20Hoon%20Cho"> Myung Hoon Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Ji%20Hoon%20Kim"> Ji Hoon Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Soo%20Hyung%20Kim"> Soo Hyung Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, we systematically investigated the effect of nanoscale energetic materials in formulations of aluminum nanoparticles (Al NPs; heat source)/copper oxide nanoparticles (CuO NPs; oxidizer) on the combustion and gas-generating properties of sodium azide microparticles (NaN3 MPs; gas-generating agent) for potential applications in gas generators. The burn rate of the NaN3 MP/CuO NP composite powder was only ~0.3 m/s. However, the addition of Al NPs to the NaN3 MP/CuO NP matrix caused the rates to reach ~5.3 m/s, respectively. In addition, the N2 gas volume flow rate generated by the ignition of the NaN3 MP/CuO NP composite powder was only ~0.6 L/s, which was significantly increased to ~3.9 L/s by adding Al NPs to the NaN3 MP/CuO NP composite powder. This suggested that the highly reactive NPs, with the assistance of CuO NPs, were effective heat-generating sources enabling the complete thermal decomposition of NaN3 MPs upon ignition. Al NPs were highly effective in the gas generators because of the increased reactivity induced by the reduced particle size. Finally, we successfully demonstrated that a homemade airbag with a specific volume of ~140 mL could be rapidly and fully inflated by the thermal activation of nanoscale energetic material-added gas-generating agents (i.e., NaN3 MP/Al NP/CuO NP composites) within the standard time of ~50 ms for airbag inflation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanoenergetic%20materials" title="nanoenergetic materials">nanoenergetic materials</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminum%20nanoparticles" title=" aluminum nanoparticles"> aluminum nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=copper%20oxide%20nanoparticles" title=" copper oxide nanoparticles"> copper oxide nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20generators" title=" gas generators"> gas generators</a> </p> <a href="https://publications.waset.org/abstracts/45745/nanoenergetic-materials-as-effective-heat-energy-sources-for-enhanced-gas-generators" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45745.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">367</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">628</span> Study on Hydrophilicity of Anodic Aluminum Oxide Templates with TiO2-NTs </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yu-Wei%20Chang">Yu-Wei Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsuan-Yu%20Ku"> Hsuan-Yu Ku</a>, <a href="https://publications.waset.org/abstracts/search?q=Jo-Shan%20Chiu"> Jo-Shan Chiu</a>, <a href="https://publications.waset.org/abstracts/search?q=Shao-Fu%20Chang"> Shao-Fu Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chien-Chon%20Chen"> Chien-Chon Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to discuss the hydrophilicity about the anodic aluminum oxide (AAO) template with titania nanotubes (NTs).

Hence, environment and instrument quality control for the stray reduction is critical for the spectral reflectance measurement. In this paper, a simple and practical method has been developed to correct a spectrometer's response for measurement errors arising from the environment's and instrument's stray light. A sinusoidal modulated light intensity signal was incident on a tested sample, and then the reflected light was collected by the spectrometer. Since a sinusoidal signal modulated the incident light, the reflected light also had a modulated frequency which was the same as the incident signal. Using the three-parameter sine curve fitting algorithm, we can extract the primary reflectance signal from the total measured signal, which contained the primary reflectance signal and the stray light from the environment. The spectra similarity between the extracted spectra by this proposed method with extreme environment stray light is 99.98% similar to the spectra without the environment's stray light. This result shows that we can measure the reflectance spectra without the affection of the environment's stray light. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spectrometer" title="spectrometer">spectrometer</a>, <a href="https://publications.waset.org/abstracts/search?q=stray%20light" title=" stray light"> stray light</a>, <a href="https://publications.waset.org/abstracts/search?q=three-parameter%20sine%20curve%20fitting" title=" three-parameter sine curve fitting"> three-parameter sine curve fitting</a>, <a href="https://publications.waset.org/abstracts/search?q=spectra%20extraction" title=" spectra extraction"> spectra extraction</a> </p> <a href="https://publications.waset.org/abstracts/138998/stray-light-reduction-methodology-by-a-sinusoidal-light-modulation-and-three-parameter-sine-curve-fitting-algorithm-for-a-reflectance-spectrometer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138998.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">248</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">626</span> Reservoir Inflow Prediction for Pump Station Using Upstream Sewer Depth Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Osung%20Im">Osung Im</a>, <a href="https://publications.waset.org/abstracts/search?q=Neha%20Yadav"> Neha Yadav</a>, <a href="https://publications.waset.org/abstracts/search?q=Eui%20Hoon%20Lee"> Eui Hoon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Joong%20Hoon%20Kim"> Joong Hoon Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Artificial Neural Network (ANN) approach is commonly used in lots of fields for forecasting. In water resources engineering, forecast of water level or inflow of reservoir is useful for various kind of purposes. Due to advantages of ANN, many papers were written for inflow prediction in river networks, but in this study, ANN is used in urban sewer networks. The growth of severe rain storm in Korea has increased flood damage severely, and the precipitation distribution is getting more erratic. Therefore, effective pump operation in pump station is an essential task for the reduction in urban area. If real time inflow of pump station reservoir can be predicted, it is possible to operate pump effectively for reducing the flood damage. This study used ANN model for pump station reservoir inflow prediction using upstream sewer depth data. For this study, rainfall events, sewer depth, and inflow into Banpo pump station reservoir between years of 2013-2014 were considered. Feed – Forward Back Propagation (FFBF), Cascade – Forward Back Propagation (CFBP), Elman Back Propagation (EBP) and Nonlinear Autoregressive Exogenous (NARX) were used as ANN model for prediction. A comparison of results with ANN model suggests that ANN is a powerful tool for inflow prediction using the sewer depth data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20network" title="artificial neural network">artificial neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=forecasting" title=" forecasting"> forecasting</a>, <a href="https://publications.waset.org/abstracts/search?q=reservoir%20inflow" title=" reservoir inflow"> reservoir inflow</a>, <a href="https://publications.waset.org/abstracts/search?q=sewer%20depth" title=" sewer depth"> sewer depth</a> </p> <a href="https://publications.waset.org/abstracts/58382/reservoir-inflow-prediction-for-pump-station-using-upstream-sewer-depth-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58382.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">317</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">625</span> Derivative Usage, Ownership Structure, and Bank Value in European Countries </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chuang-Chang%20Chang">Chuang-Chang Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Keng-Yu%20Ho"> Keng-Yu Ho</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Jen%20Hsiao"> Yu-Jen Hsiao</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsin-Ni%20Yang"> Hsin-Ni Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Using a sample of detailed ownership data of 1,032 listed commercial bank observations in 30 European countries from 2004 to 2010, we explore what categories of shareholder are more likely to use derivatives and how different types of owners affect the bank value.

Experimental results on several low-contrast images have shown that our proposed approach can produce natural and appealing enhanced images. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=image%20enhancement" title="image enhancement">image enhancement</a>, <a href="https://publications.waset.org/abstracts/search?q=multiscale%20retinex" title=" multiscale retinex"> multiscale retinex</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20fusion" title=" image fusion"> image fusion</a>, <a href="https://publications.waset.org/abstracts/search?q=EGMSR" title=" EGMSR"> EGMSR</a> </p> <a href="https://publications.waset.org/abstracts/15139/color-image-enhancement-using-multiscale-retinex-and-image-fusion-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15139.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">458</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">621</span> Evaluation of Duncan-Chang Deformation Parameters of Granular Fill Materials Using Non-Invasive Seismic Wave Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Pegah">Ehsan Pegah</a>, <a href="https://publications.waset.org/abstracts/search?q=Huabei%20Liu"> Huabei Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Characterizing the deformation properties of fill materials in a wide stress range always has been an important issue in geotechnical engineering. The hyperbolic Duncan-Chang model is a very popular model of stress-strain relationship that captures the nonlinear deformation of granular geomaterials in a very tractable manner. It consists of a particular set of the model parameters, which are generally measured from an extensive series of laboratory triaxial tests. This practice is both time-consuming and costly, especially in large projects. In addition, undesired effects caused by soil disturbance during the sampling procedure also may yield a large degree of uncertainty in the results. Accordingly, non-invasive geophysical seismic approaches may be utilized as the appropriate alternative surveys for measuring the model parameters based on the seismic wave velocities. To this end, the conventional seismic refraction profiles were carried out in the test sites with the granular fill materials to collect the seismic waves information. The acquired shot gathers are processed, from which the P- and S-wave velocities can be derived. The P-wave velocities are extracted from the Seismic Refraction Tomography (SRT) technique while S-wave velocities are obtained by the Multichannel Analysis of Surface Waves (MASW) method. The velocity values were then utilized with the equations resulting from the rigorous theories of elasticity and soil mechanics to evaluate the Duncan-Chang model parameters. The derived parameters were finally compared with those from laboratory tests to validate the reliability of the results. The findings of this study may confidently serve as the useful references for determination of nonlinear deformation parameters of granular fill geomaterials. Those are environmentally friendly and quite economic, which can yield accurate results under the actual in-situ conditions using the surface seismic methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Duncan-Chang%20deformation%20parameters" title="Duncan-Chang deformation parameters">Duncan-Chang deformation parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=granular%20fill%20materials" title=" granular fill materials"> granular fill materials</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20waves%20velocity" title=" seismic waves velocity"> seismic waves velocity</a>, <a href="https://publications.waset.org/abstracts/search?q=multichannel%20analysis%20of%20surface%20waves" title=" multichannel analysis of surface waves"> multichannel analysis of surface waves</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20refraction%20tomography" title=" seismic refraction tomography"> seismic refraction tomography</a> </p> <a href="https://publications.waset.org/abstracts/106481/evaluation-of-duncan-chang-deformation-parameters-of-granular-fill-materials-using-non-invasive-seismic-wave-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106481.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">182</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">620</span> Monitoring and Analysis of Bridge Crossing Ground Fissures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhiqing%20Zhang">Zhiqing Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiangong%20Zhou"> Xiangong Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Zihan%20Zhou"> Zihan Zhou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ground fissures can be seen in some cities all over the world.

The damage to Chang'an Road interchange is the most serious and typical. To study the influence of ground fissures on the bridge, we established a bridge monitoring system. The main monitoring items include elevation monitoring, structural displacement monitoring, etc. The monitoring results show that the typical failure is mainly reflected in the bridge deck damage caused by horizontal tension and vertical dislocation. For the construction of urban interchange spanning ground fissures, the interchange should be divided reasonably, a simple support structure with less restriction should be adopted, and the monitoring of supports should be strengthened to prevent the occurrence of beam falling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bridge%20monitoring" title="bridge monitoring">bridge monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20fissures" title=" ground fissures"> ground fissures</a>, <a href="https://publications.waset.org/abstracts/search?q=typical%20disease" title=" typical disease"> typical disease</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20displacement" title=" structural displacement"> structural displacement</a> </p> <a href="https://publications.waset.org/abstracts/150133/monitoring-and-analysis-of-bridge-crossing-ground-fissures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150133.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">223</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">619</span> Impact of Education on Levels of Physical Activity and Depression in Taiwanese Vegetarians and Omnivores</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ya-Lin%20Chang">Ya-Lin Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chia%20Chen%20Chang"> Chia Chen Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Ru%20Liang"> Yu-Ru Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Joyce%20Chen"> Joyce Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=You-Kang%20Chang"> You-Kang Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Tina%20Chiu"> Tina Chiu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Physical activity and mental health status are important for health. The purpose of this study was to examine levels of physical activities and depression in Taiwanese vegetarians (VEG) and omnivores (OMNI). Sixty-three vegetarians (20 males) and 56 omnivores (23 males) with an average age of 51 years were recruited for a food frequency validation study at Taipei Tzu Chi Hospital from July to September in 2016. Participants filled out a validated Chinese version international physical activity questionnaire-short-form (IPAQ), Beck Depression Inventory-II-Chinese version (BDI), food frequency questionnaire (FFQ) and a questionnaire on demographics and medical history upon recruitment. Total BDI scores were calculated for depression and the metabolic equivalent of task (MET) was calculated for physical activity levels. Mann-Whitney U tests and Chi-square test were used to compare demographics, physical activity levels and depression scores. VEG and OMNI did not differ significantly on MET (1441.9 ± 3387.3 vs. 1605.8 ± 2486.1. p=0.2652, respectively). VEG scored slightly lower on BDI compared to OMNI without statistical significance (5.6 ± 5.7 vs. 7.4 ± 6.3. p=0.06). In addition, we found that regardless of diet practice, those who held a college degree and above scored better on MET (1788.1 ± 2532.6 vs. 1215.5 ± 3425.5. p=0.0014) and BDI (5.2 ± 5.1 vs. 7.8 ± 6.7. p=0.03). In this cross-sectional study, Taiwanese vegetarians and omnivores scored comparatively on physical activity levels and depression. However, education is a significant determinant of physical activity and depression. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BDI" title="BDI">BDI</a>, <a href="https://publications.waset.org/abstracts/search?q=diet" title=" diet"> diet</a>, <a href="https://publications.waset.org/abstracts/search?q=education" title=" education"> education</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20activity" title=" physical activity"> physical activity</a> </p> <a href="https://publications.waset.org/abstracts/63901/impact-of-education-on-levels-of-physical-activity-and-depression-in-taiwanese-vegetarians-and-omnivores" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63901.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">389</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">618</span> Impact of Climate Change on Water Resource Systems in Taiwan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chia-Ling%20Chang">Chia-Ling Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hao-Bo%20Chang"> Hao-Bo Chang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Global climate change alters rainfall characteristics, while the variation of these characteristics further influences environmental conditions, such as hydrologic responses, landslide areas, and the amounts of diffuse pollution. The variations of environmental conditions may impact the stability of water resource systems. The objective of this study is to assess the present conditions of major water resource systems in Taiwan. The impact of climate change on each system is also discussed herein. Compared to the water resource systems in northern Taiwan, the ratio of the precipitation during the rainy season to that during the dry season has a larger increase in southern Taiwan. This variation of hydrologic condition impacts the stability of water resource systems and increases the risk of normal water supply.

Our survey area were the Anmok beach in Gangneung, South Korea. We made Shipborne Mobile LiDAR System for these survey. Shipborne Mobile LiDAR System includes LiDAR (RIEGL LMS-420i), IMU ((Inertial Measurement Unit, MAGUS Inertial+) and RTKGNSS (Real Time Kinematic Global Navigation Satellite System, LEIAC GS 15 GS25) for beach's measurement, LiDAR's motion compensation & precise position. Shipborne Mobile LiDAR System scans beach on the movable vessel using the laser. We mounted Shipborne Mobile LiDAR System on the top of the vessel. Before beach survey, we conducted eight circles IMU calibration survey for stabilizing heading of IMU. This exploration should be as close as possible to the beach. But our vessel could not come closer to the beach because of latency objects in the water. At the same time, we conduct submarine topography survey using multi-beam echo sounder EM3001. A multi-beam echo sounder is a device observing and recording the submarine topography using sound wave. We mounted multi-beam echo sounder on left side of the vessel. We were equipped with a motion sensor, DGNSS (Differential Global Navigation Satellite System), and SV (Sound velocity) sensor for the vessel's motion compensation, vessel's position, and the velocity of sound of seawater. Shipborne Mobile LiDAR System was able to reduce the consuming time of beach survey rather than previous conventional methods of beach survey. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anmok" title="Anmok">Anmok</a>, <a href="https://publications.waset.org/abstracts/search?q=beach%20survey" title=" beach survey"> beach survey</a>, <a href="https://publications.waset.org/abstracts/search?q=Shipborne%20Mobile%20LiDAR%20System" title=" Shipborne Mobile LiDAR System"> Shipborne Mobile LiDAR System</a>, <a href="https://publications.waset.org/abstracts/search?q=submarine%20topography" title=" submarine topography"> submarine topography</a> </p> <a href="https://publications.waset.org/abstracts/65092/submarine-topography-and-beach-survey-of-gang-neung-port-in-south-korea-using-multi-beam-echo-sounder-and-shipborne-mobile-light-detection-and-ranging-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65092.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">429</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">616</span> Local Activities of the Membranes Associated with Glycosaminoglycan-Chitosan Complexes in Bone Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chih-Chang%20Yeh">Chih-Chang Yeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Min-Fang%20Yang"> Min-Fang Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsin-I%20Chang"> Hsin-I Chang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Chitosan is a cationic polysaccharide derived from the partial deacetylation of chitin. Hyaluronic acid (HA), chondroitin sulfate (CS) and heparin (HP) are anionic glycosaminoglycans (GCGs) which can regulate osteogenic activity. In this study, chitosan membranes were prepared by glutaraldehyde crosslinking reaction and then complexed with three different types of GCGs. 7F2 osteoblasts-like cells and macrophages Raw264.7 were used as models to study the influence of chitosan membranes on osteometabolism. Although chitosan membranes are highly hydrophilic, the membranes associated with GCG-chitosan complexes showed about 60-70% cell attachment. Furthermore, the membranes associated with HP-chitosan complexes could increase ALP activity in comparison with chitosan films only. Three types of the membranes associated with GCG-chitosan complexes could significantly inhibit LPS induced-nitric oxide expression. In addition, chitosan membranes associated with HP and HA can down-regulate tartrate-resistant acid phosphatase (TRAP) activity but not CS-chitosan complexes. Based on these results, we conclude that chitosan membranes associated with HP can increase ALP activity in osteoblasts and chitosan membranes associated with HP and HA reduce TRAP activity in osteoclasts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=osteoblast" title="osteoblast">osteoblast</a>, <a href="https://publications.waset.org/abstracts/search?q=osteoclast" title=" osteoclast"> osteoclast</a>, <a href="https://publications.waset.org/abstracts/search?q=chitosan" title=" chitosan"> chitosan</a>, <a href="https://publications.waset.org/abstracts/search?q=glycosaminoglycan" title=" glycosaminoglycan"> glycosaminoglycan</a> </p> <a href="https://publications.waset.org/abstracts/3820/local-activities-of-the-membranes-associated-with-glycosaminoglycan-chitosan-complexes-in-bone-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3820.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">527</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">615</span> Unsteady Simulation of Burning Off Carbon Deposition in a Coke Oven</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Uzu-Kuei%20Hsu">Uzu-Kuei Hsu</a>, <a href="https://publications.waset.org/abstracts/search?q=Keh-Chin%20Chang"> Keh-Chin Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Joo-Guan%20Hang"> Joo-Guan Hang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chang-Hsien%20Tai"> Chang-Hsien Tai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Carbon Deposits are often occurred inside the industrial coke oven during the coking process.

The burning off carbon deposition in coke oven performed by Computational Fluid Dynamics (CFD) method has provided an evaluation of the feasibility study. A three-dimensional, transient, turbulent reacting flow simulation has performed with three different injecting air flow rate and another kind of injecting configuration. The result shows that injection higher air flow rate would effectively reduce the carbon deposits.

This man-made fiber is prepared from petroleum chemicals, which may cause environmental pollution and resource exhausting issues, such as the use of non-renewable sources, greenhouse gas emission and discharge of wastewater. Therefore, the textile made by recycle-PET is the trend in the future. Recycle-PET fiber, compared with petroleum-made PET, shows lower carbon emissions and resource exhaustion. However, “fabric decoloring” is the key barrier to textile recycling. The dyes existing in the fabrics may cause PET chain degradation and appearance drawbacks during the textile recycling process. In this research, the water-based decoloring agent was used to remove the dispersed dye in the PET fabrics in order to obtain the colorless PET fabrics after the decoloring process. The decoloring rate of PET fabrics after the decoloring process was up to 99.0%. This research provides a better solution to resolve the issues of appearance and physical properties degradation of fabrics-recycle PET materials due to the residual dye.

Because of the friction heat of air flow with high speed on the surface of the vehicle, it is not easy to cool the superheat of the vehicle by the simple air cooling method. For this reason, a cooling method through endothermic heat is attracting attention by using a fuel that causes an endothermic reaction in a high-speed vehicle. There are two main ways of cooling the fuel through the endothermic reaction. The first is physical heat absorption. When the temperature rises, there is a sensible heat that accompanies it. The second is the heat of reaction corresponding to the chemical heat absorption, which absorbs heat during the fuel decomposes. Generally, since the decomposition reaction of the fuel proceeds at a high temperature, it does not achieve a great efficiency in cooling the high-speed flight body. However, when the catalyst is used, decomposition proceeds at a low temperature thereby increasing the cooling efficiency. However, when the catalyst is used as a powder, the catalyst enters the engine and damages the engine or the catalyst can deteriorate the performance due to the sintering. On the other hand, when used in the form of pellets, catalyst loss can be prevented. However, since the specific surface of pellet is small, the efficiency of the catalyst is low. And it can interfere with the flow of fuel, resulting in pressure loss and problems with fuel injection. In this study, we tried to maximize the performance of the catalyst by preparing a hollow fiber type pellet for zeolite ZSM-5, which has a higher amount of heat absorption, than other conventional pellets. The hollow fiber type pellet was prepared by phase inversion method. The hollow fiber type pellet has a finger-like pore and sponge-like pore. So it has a higher specific surface area than conventional pellets. The crystal structure of the prepared ZSM-5 catalyst was confirmed by XRD, and the characteristics of the catalyst were analyzed by TPD/TPR device. This study was conducted as part of the Basic Research Project (Pure-17-20) of Defense Acquisition Program Administration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=catalyst" title="catalyst">catalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=endothermic%20reaction" title=" endothermic reaction"> endothermic reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=high-speed%20vehicle%20cooling" title=" high-speed vehicle cooling"> high-speed vehicle cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=zeolite" title=" zeolite"> zeolite</a>, <a href="https://publications.waset.org/abstracts/search?q=ZSM-5" title=" ZSM-5"> ZSM-5</a> </p> <a href="https://publications.waset.org/abstracts/80210/a-study-on-the-performance-improvement-of-zeolite-catalyst-for-endothermic-reaction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80210.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">312</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">612</span> Study Case of Spacecraft Instruments in Structural Modelling with Nastran-Patran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Borja%20de%20Lara">Francisco Borja de Lara</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Ravanbakhsh"> Ali Ravanbakhsh</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20F.%20Wimmer-Schweingruber"> Robert F.

In this conference, we present the structural analysis of the Lunar Lander Neutron Dosimetry (LND) experiment on the Chang'E4 mission, the first probe to land on the moon’s far side included in the Chinese’ Moon Exploration Program by the Chinese National Space Administration. To this target, the software Nastran/Patran has been used: a structural model in Patran and a structural analysis through Nastran have been realized. Next, the results obtained are used both for the optimization process of the spacecraft structure, and as input parameters for the model structural test campaign. In this way, the feasibility of the lunar instrument structure is demonstrated in terms of the modal modes, stresses, and random vibration and a better understanding of the structural tests design is provided by our results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chang%E2%80%99E4" title="Chang’E4">Chang’E4</a>, <a href="https://publications.waset.org/abstracts/search?q=Chinese%20national%20space%20administration" title=" Chinese national space administration"> Chinese national space administration</a>, <a href="https://publications.waset.org/abstracts/search?q=lunar%20lander%20neutron%20dosimetry" title=" lunar lander neutron dosimetry"> lunar lander neutron dosimetry</a>, <a href="https://publications.waset.org/abstracts/search?q=nastran-patran" title=" nastran-patran"> nastran-patran</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20analysis" title=" structural analysis"> structural analysis</a> </p> <a href="https://publications.waset.org/abstracts/71329/study-case-of-spacecraft-instruments-in-structural-modelling-with-nastran-patran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71329.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">529</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">611</span> An Extended Basic Period and Power-of-Two Policy for Economic Lot-Size Batch-Shipment Scheduling Problem</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wen-Tsung%20Ho">Wen-Tsung Ho</a>, <a href="https://publications.waset.org/abstracts/search?q=Ku-Kuang%20Chang"> Ku-Kuang Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsin-Yuan%20Chang"> Hsin-Yuan Chang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, we consider an economic lot-size batch-shipment scheduling problem (ELBSP) with extended basic period (EBP) and power-of-two (PoT) policies. In this problem, the supplier using a single facility to manufacture multiple products and equally sized batches are then delivered by the supplier to buyers over an infinite planning horizon. Further, the extended basic period (EBP) and power-of-two (PoT) policy are utilized. Relaxing the production schedule converts the ELBSP to an economic lot-size batch-shipment problem (ELBP) with EBP and PoT policies, and a nonlinear integer programming model of the ELBP is constructed. Using the replenishment cycle division and recursive tightening methods, optimal solutions are then solved separately for each product. The sum of these optimal solutions is the lower bound of the ELBSP. A proposed heuristic method with polynomial complexity is then applied to figure out the near-optimal solutions of the ELBSP. Numerical example is presented to confirm the efficacy of the proposed method. <p class="card-text"><strong>Keywords:</strong> <a
