ANALISIS PENGGUNAAN APLIKASI HANPING CHINESE DICTIONARY LITE TERHADAP PENGUASAAN KOSAKATA BAHASA MANDARIN PADA MAHASISWA KELAS A ANGKATAN 2019 PENDIDIKAN BAHASA MANDARIN FKIP UNTAN
No full textVocabulary plays a vital role in every language. At present, many educational media are developed as auxiliary tools for language learning, such as Hanping Chinese Dictionary Lite. Hanping Chinese Dictionary Lite is an electronic dictionary that can help learners learn Chinese vocabulary. This study aims to understand the efficiency of students using the Hanping Chinese Dictionary Lite and students' evaluation of the Hanping Chinese Dictionary Lite. This study uses three research methods: test method, questionnaire survey method, and interview method. The results of the test and questionnaire survey show that the use of Hanping Chinese Dictionary Lite can effectively improve students' Chinese vocabulary. Because after using the dictionary software, the student's mastery of Chinese language has improved, that is, the result of the test is 60% and the result of the questionnaire is 53.50%. In the learning process, the author adopts six steps: showing the mobile phone dictionary to the students, conducting a pre-test, implementing the mobile phone dictionary, conducting a post-test, conducting a questionnaire survey, and conducting interviews. The final results of the interviews show that the evaluation of the dictionary software by the students is very good. It can be said that the students are satisfied with the use of the Hanping Chinese Dictionary Lite and think it is worth using the software

No full textEstimation of Seismic Loss for a Portfolio of Buildings under Bidirectional Horizontal Ground Motions due to a Scenario Cascadia Event
No full textEarthquake ground motions induced by a scenario event are spatially (partially) correlated and (partially) coherent. Simulated ground motion records can be used to carry out nonlinear inelastic time history analysis for a portfolio of buildings to estimate the seismic loss, which is advantageous as there is no need to develop and apply empirical ground motion prediction equations and the ductility demand rules, or to search the scenario-compatible recorded records at selected sites that may not exist. Further, if the structures being considered are sensitive to the orientation of the excitation, multiple-component ground motion records are needed. For the simulation of such ground motion records, previous studies have shown that correlation and coherency between any pair of ground motion components need to be incorporated. In this study, the seismic loss of a portfolio of hypothetical buildings in downtown Vancouver under bidirectional horizontal ground motions due to a scenario Cascadia event is estimated by using simulated bidirectional ground motion records that include realistic correlation and coherency characteristics. The hysteretic behaviors of the buildings are described by bidirectional Bouc–Wen model. The results show that the use of unidirectional ground motions and single-degree-of-freedom system structural model may underestimate the aggregated seismic loss

A Comparative Study of Different Reconstruction Schemes for a Reconstructed Discontinuous Galerkin Method on Arbitrary Grids
No full textA comparative study of different reconstruction schemes for a reconstruction-based discontinuous Galerkin, termed RDG(P1P2) method is performed for compressible flow problems on arbitrary grids. The RDG method is designed to enhance the accuracy of the discontinuous Galerkin method by increasing the order of the underlying polynomial solution via a reconstruction scheme commonly used in the finite volume method. Both Green-Gauss and least-squares reconstruction methods and a least-squares recovery method are implemented to obtain a quadratic polynomial representation of the underlying discontinuous Galerkin linear polynomial solution on each cell. These three reconstruction/recovery methods are compared for a variety of compressible flow problems on arbitrary meshes to access their accuracy and robustness. The numerical results demonstrate that all three reconstruction methods can significantly improve the accuracy of the underlying second-order DG method, although the least-squares reconstruction method provides the best performance in terms of both accuracy and robustness
