An Analysis of <i>Judge Lin</i>
No full textBiography of Lin Wen Zhong Gong has another way to call, that is Judge Lin. The leading character is Lin Ze-Xu. This book is based on functionary experience of Lin Ze-Xu, with the captivating plots of court case, helping by highly skilled military attach\uc3\ua9s and chivalrous knights, and the history facts of Opium War. It makes Lin Ze-Xu\ue2s Confucian temperament and tragic mood more, also contrasts with author\ue2s sorrow and furiousness for the politics at the time. History, court case, martial arts\ue2\ua6\ue2\ua6etc. are essence of this book and it broadens the way of this writing style.
The topic of the thesis is \ue2An Analysis of Judge Lin\ue2. The following thesis will be divided into six different chapters. The introduction is Chapter one of the thesis, which is including researching motive and purpose, literature review of predecessors, researching version by existing information, raising questions, choosing research methods and arranging chapters. In chapter Two, I discuss the study of characters of Lin Ze-Xu, also makes a deep analysis of author\u27s purpose of writing him. In chapter Three, I analyze supporting actors and actress. Meanwhile, I illustrate author\u27s purpose of writing supporting actress because the author had different manner to describe supporting actress. Moving to the Chapter Four, I mainly focus on the plots of Judge Lin, and organize cases of Lin Ze-Xu and his subordinates to understand features of cases. In Chapter Five, I represent the causes of Opium War. China and England had difference of opinions of opium. Therefore, it is easier to comprehend what the author\u27s purpose is. In the last chapter I summarize the main points of the preceding chapters and confirm particularity of Judge Lin
Active vibration isolation performance of the bistable nonlinear electromagnetic actuator with the elastic boundary
No full textThis paper thoroughly investigates the broadband active vibration isolation of a bistable nonlinear electromagnetic actuator with an elastic boundary (simply named EB-bistable actuator). A new feedback control law is proposed to control the actuator's input current, to significantly attenuate the broadband vibration transmissibility from the base excitation to the actuator mover (supporting the payload). The control law comprises the polynomial function of the mover's absolute velocity. The mathematical models of the EB-bistable actuator and its application for vibration isolation are derived and experimentally validated. Then, based on the verified model, the paper comprehensively investigates the EB-bistable actuator with the proposed control law, which validates the broadband active vibration isolation performance for different system parameters. The input-to-state stability (ISS) of the control law for any non-negative control weights is proved, and thus it is a model-free control method. Results of one investigated case show that the maximum vibration transmissibility can be attenuated by over 90%. The lower bound of the effective vibration isolation bandwidth (where the vibration transmissibility is smaller than 0 dB) is reduced by 19.69%, i.e. the bandwidth is significantly broadened. Moreover, the study proves the effectiveness of the active vibration isolation for the structural variation and initial condition change. Finally, the paper thoroughly discusses the influence of the control law parameters on the active vibration isolation performance. The parametric studies develop useful guidelines for the active vibration isolation of the EB-bistable actuator.</p

Machine learning based prediction of piezoelectric energy harvesting from wake galloping
No full textWake galloping is a phenomenon of aerodynamic instability and has vast potential inenergy harvesting. This paper investigates the vibration response of wake galloping piezo-electric energy harvesters (WGPEHs) in different configurations. In the proposed system, astationary obstacle is placed upstream, and a cuboid bluff body mounted on a cantileverbeam with piezoelectric sheets attached to it, is placed downstream. Three different typesof WGPEHs were tested with different cross-section S of the upstream obstacles, namelysquare, triangular, and circular. At the same time, the tests were conducted by changing theequivalent diameter ratio g ¼ 1 2:5 of the upstream and downstream objects, the dimen-sionless distance between two objects’ centers L ¼ L=D ¼ 2 8, and the velocity spanU ¼ 2:93 14:54. The results reveal that S , g, L and U have significant effect on thevibration response of WGPEHs. Then, considering these four parameters as input features,this study has trained machine learning (ML) models to predict the root mean square val-ues of the voltage (V rms ) and the maximum displacement (ymax), respectively. The perfor-mance of three different ML algorithms including decision tree regressor (DTR), randomforest (RF), and gradient boosting regression trees (GBRT) on predicting V rms and ymax werecompared. Among them, the GBRT model performed optimally in predicting the V rms andymax . The GBRT model provides accurate predictions to V rms and ymax within the test range of S , g, L and U.<br/
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Lowest electronic states of neutral and ionic LiN
No full textWe have investigated the potential energy curves (PECs) of the LiN heteronuclear diatomic molecule, including its ionic species LiN+ and LiN−, using explicitly correlated multi-reference configuration interaction (MRCI-F12) calculations in conjunction with the correlation consistent quintuple- basis set. The effect of core–valence correlation, scalar relativistic effects, and the size of the basis sets has been investigated. A comprehensive set of spectroscopic constants determined based on the above-mentioned calculations are also reported for the lowest electronic states and all systems, including dissociation energies, harmonic and anharmonic vibrational frequencies, and rotational constants. Additional parameters, such as the dipole moments, equilibrium spin-orbit constants, excitation energies, and rovibrational energy levels, are also documented. We found that the three triplet states of LiN, namely, X 3∑−, A 3Π, and 2 3∑−, exhibit substantial potential wells in the PEC diagrams, while the quintet states are repulsive in nature. The ground state of the anion also shows a deep potential well in the vicinity of its equilibrium geometry. In contrast, the ground and excited states of the cation are very loosely bound. Charge transfer properties of each of these states are also analyzed to obtain an in-depth understanding of the interatomic interactions. We found that the core–valence correlation has a substantial effect on the calculated spectroscopic constants.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Atmospheric Remote Sensin

Does Downloading PowerPoint Slides Before the Lecture Lead to Better Student Achievement?: Reply
No full textThis reply responds to a comment by Cannon (2011) that opens the debate on consistency of the effect of downloading PowerPoint slides before lectures on students’ exam performance. Cannon (2011) points out potential endogeneity problems in Chen and Lin (2008) and attempts to explore the unconditional mean effect of downloading PowerPoint slides for the full sample. In this reply, we firstly argue that the estimates in our original article are consistent since the effect of interest is the “conditional†treatment effect but not the unconditional mean effect. We provide explanations for our rationale of estimating the “conditional†treatment effect. Secondly, we propose a modified downloading variable to replicate Cannon’s analysis. Our results suggest that downloading PowerPoint slides before the exam does not produce a significant effect on absent students’ exam performance which is different from the results in Cannon (2011). Our analysis does support Cannon’s argument that students fixed effects are different across different attendance status.

Abstract
By：Chou chen- tsung Advisor：Lin en-chung
The purpose of this research is to understand the current situation of the citizen’s subjective impressions on the spouses from Mainland China and Vietnam in Shu Lin City. The survey is carried out by self-designed questionnaires. The parents of the students in 10 ele mentary schools of Shu Lin City were taken as samples, 1000 que stionnaires were released, in which 825 effective copies were responded and returned (reaching a 93.0% share of all return questionnaires). The methods for analyzing the data are adopted from SPSS Statistic Software, which includes avera
ges, standard deviation,t-test,ANOVA…etc to analyze.The main findings are as below:
1. The subjective impression of Shu Lin citizens on the
Mainland spouses tends to be “ordinary” to “slightly
good.”
2. Regarding the subjective impression of Shu Lin citizens
on the Mainland spouses, there is a significant
difference on the four out of six different variants,
which are gender, occupations, marital status, and their
experience of contacting Mainland China spouses.
3. The subjective impression of Shu Lin citizens on the
Vietnamese spouses tends to be “ordinary”to “slightly
good.”
4. Regarding the subjective impression of Shu Lin citizens
on the Vietnamese spouses, there is a significant
difference on the three out of six different variants,
which are occupations, marital status, and educational
background.
5. There is a significant difference on the citizens’
subjective impres sion between the spouses from Mainland
China and those from Vietnam.
“Focus Group Interview” was also practiced to enrich the study. Based on the research result, some suggestions regarding the effective community educational policies are proposed.
1.Publicize the positive impressions of Shu Lin citizens
toward the spouses from Mainland China and Vietnam.
2.More researches and studies should be done by th
government and the academic institutes in order to
facilitate the positive understanding.
3.Encourage the positive reports from the media which
should be carefully regulated by the government and the
non-gover nmental organizations.
4.For schools, enhance multicultural teaching
environment;for the government, host more multicultural
exhibitions about the spouses from Mainland and Vietnam.
5.Make good use of the resources from schools and
communities to popularize the idea of “multicultural
community educati on” as well as to facilitate the
integration of different races.
6.The spouses from Mainland and Vietnam should learn
actively and positively to adapt themselves to the
lifestyles of the ir family and the community; therefore,
they are able to gain more positive interaction and
feedback from the peoplein the community.
