Bridges are the most useful part in the transportation *** disruption of the bridge structures may hamper the whole transportation *** the last recent tsunamis,numerous number of bridges were structurally damaged by the tsunami *** of proper provisions of tsunami forces in the design guidelines also contributes to the augmentations of the damage ***,proper evaluation of the tsunami forces on the bridge girder should be introduced in the design *** this study,laboratory experiments were carried out to reveal the damage mechanism of the bridge girder by assessing the exerted tsunami *** broken and unbroken waves were considered for the *** results showed that measured forces were larger for broken waves than those of unbroken *** force of the broken waves was 4.59 times as large as the hydrostatic ***,waves reached the peak value more rapidly for larger wave heights than those of smaller ***,a girder that is placed at a higher position is much vulnerable to tsunami hazard.

The recognition of pathological voice is considered a difficult task for speech ***,otolaryngologists needed to rely on oral communication with patients to discover traces of voice pathologies like dysphonia that are caused by voice alteration of vocal folds and their accuracy is between 60%–70%.To enhance detection accuracy and reduce processing speed of dysphonia detection,a novel approach is proposed in this *** have leveraged Linear Discriminant Analysis(LDA)to train multiple Machine Learning(ML)models for dysphonia *** ML models are utilized like Support Vector Machine(SVM),Logistic Regression,and K-nearest neighbor(K-NN)to predict the voice pathologies based on features like Mel-Frequency Cepstral Coefficients(MFCC),Fundamental Frequency(F0),Shimmer(%),Jitter(%),and Harmonic to Noise Ratio(HNR).The experiments were performed using Saarbrucken Voice Data-base(SVD)and a privately collected *** K-fold cross-validation approach was incorporated to increase the robustness and stability of the ML *** to the experimental results,our proposed approach has a 70%increase in processing speed over Principal Component Analysis(PCA)and performs remarkably well with a recognition accuracy of 95.24%on the SVD dataset surpassing the previous best accuracy of 82.37%.In the case of the private dataset,our proposed method achieved an accuracy rate of 93.37%.It can be an effective non-invasive method to detect dysphonia.

面向孟加拉学生的高级汉语成语教学研究

面向孟加拉学生的高级汉语成语教学研究

成语是汉语词汇的重要组成部分,它们绝大多数源于经典文本和历史事件。在现代汉语中,成语被广泛运用于各种语境中,其深刻的意义和文化内涵也为语言的表达和交流增添了无穷的魅力。学习和掌握成语需要学生对语言运用的理解和丰富的词汇... 详细信息

成语是汉语词汇的重要组成部分,它们绝大多数源于经典文本和历史事件。在现代汉语中,成语被广泛运用于各种语境中,其深刻的意义和文化内涵也为语言的表达和交流增添了无穷的魅力。学习和掌握成语需要学生对语言运用的理解和丰富的词汇积累。由此可见,成语教学往往需要涉及到教师对中国历史文化知识和中国思维方式更深层次的理解。学会运用成语是掌握汉语典雅文体的重要一步,因而成语教学一直是高级对外汉语词汇教学中需要重视的项目。此外,尽管大多数汉语学习者们都对成语学习怀有浓厚的兴趣,但是对于汉语作为第二语言的外国学习者来说,学习成语具有一定的难度,尤其是对于孟加拉国的中文学习者们。因此,本研究的主要目的是通过对比汉语和孟加拉语中的成语,找到其相似性和差异性,进而帮助孟加拉国学生学习和掌握汉语成语,增强他们对于汉语成语的理解和使用能力,从而更好地理解中华文化。这篇论文研究了孟加拉汉语学习者在学习汉语成语时所遇到的问题和困难,并提出了教学建议。论文首先介绍了研究的背景、目的、和意义,总结了关于对外汉语教学中成语教学的现状,孟加拉汉语教育的情况,以及学生学习汉语成语时所面临的问题。其次,论文重点研究了《国际中文教育中文水平等级标准》中的汉语成语,并进行了汉孟(汉语和孟加拉语)对比考察,探讨了影响孟加拉学生成语学习的语言和文化因素。论文还采用了问卷调查的方式,对110位孟加拉汉语学习者进行了调查,分析了他们成语学习需求以及使用成语教学方法的调查结果。最后,结合影响孟加拉学生在学习成语过程中所受到的语言和文化因素,提出了教学建议,以帮助他们更好地理解成语并避免误用。
