Angular Velocity Observer for Attitude Tracking on SO(3) with the Separation Property

Tse-Huai Wu,이태영 제어·로봇·시스템학회 2016 International Journal of Control, Automation, and Vol.14 No.5

This paper studies a rigid body attitude tracking control problem with attitude measurements only, whenangular velocity measurements are not available. An angular velocity observer is constructed such that the estimatedangular velocity is guaranteed to converge to the true angular velocity asymptotically from almost all initialestimates. As it is developed directly on the special orthogonal group, which completely avoids singularities, complexities,or discontinuities caused by minimal attitude representations or quaternions. Then, the presented observeris integrated with a proportional-derivative attitude tracking controller to show a separation type property, whereexponential stability is guaranteed for the combined observer and attitude control system.

TSE Hau Yi,LEUNG Sze Yu,LEUNG Sau Fong,Grace WK HO,MAK Yim Wah 한국간호과학회 2021 한국간호과학회 학술대회 Vol.2021 No.10

Aim(s): This review summarized the effectiveness of mental health education interventions on mental health literacy and stigmatizing attitudes among secondary school students. Method(s): A systematic search of relevant Chinese and English language peer-reviewed journals was conducted in five databases (MEDLINE, PubMed, ERIC, CNKI) using keywords, such as “adoles*”, “mental health education” and “mental health literacy or mental health stigma”. Experimental studies published from 2011 to July 2021 were included. A narrative synthesis of findings was conducted. Result(s): Nineteen studies with 11,572 participants were included in this review, including 1 RCT, 4 clustered RCTs, 7 non-randomized controlled trials and 7 single group pre-test post-test design. The school-based mental health interventions among adolescents took place in both Western and non-Western countries. All of them were conducted in face-to-face approach. A diversity of educational activities were adopted. They included sharing of the patients or people in recovery of mental illness, using case vignette or video to depict mental illness. Most of the studies found the education programs were effective in improving mental health literacy and reducing stigma. Conclusion(s): While most of the studies found their outcomes are statistically significant, there are concerns over the effects of the study outcomes due to the heterogeneity among the included studies resulting from variability of measurements used with questioned reliability and validity. Future research might be suggested focusing on the measurements to appropriately evaluate the effectiveness of mental health literacy and stigmatizing attitude. Educators might consider the strengths and weaknesses of the programs to choose suitable content and mode of delivery for mental health education.

홍콩의 비중국어권 유치원생들은 중국어 학습 과정 중에 많은 어려움을 겪게 된다. 개인적인 이유 외에도 교사와 학교 모두 자원, 교재, 경험 등의 부족으로 이들의 중국어 학습은 도전적 상황에 직면해있다. 최근 홍콩 평등기회위원회(香港平等機會委員會)는 중국어권 학습자와 비중국어권 학습자의 통합교육을 적극적으로 건의하였는데, 본래의 좋은 취지와는 다르게 여러 가지 새로운 문제점들이 제기되는 결과를 가져왔다. 이러한 어려움을 해결하기 위해 홍콩 경마자선기금(香港賽馬會慈善基金)과 관련 협력 기관에서는 큰 규모의 연구를 기획하고 실제 프로그램을 개발하여 비중국어권 유치원 교육을 지원하였다. 다양한 프 로그램 가운데, 본 연구는 언어 학습 이론과 효과적인 교육에 중점을 두고, 수업 현장 관찰, 수업 비디오 녹화, 교장과 교사 인터뷰, 학습자 언어 학습 평가와 같은 연구 방법을 사용하 여 연구를 진행하였다. 본 연구는 비중국어권 유아를 대상으로, 유아반에서 상위반까지의 언어학습 발달과정을 추적 하여 네 차례 언어학습 평가를 진행하였다. 학습자의 3년간의 언어 성적은 뚜렷한 성장을 보였는데, 이를 통해 학습이론과 실제 교육법 사이에 분명한 효과가 있음을 알 수 있었다. 또한 본 연구가 통합 정리한 10종의 언어학습이론은 홍콩의 중국어권 유아와 비중국어권 유아의 통합교육에 매우 적합했고, 본 연구에서 얻어진 여러 실제 사례들은 간단히 실행 가능할 뿐만 아니라 많은 자원이 투입되지 않는다는 사실도 도출해 내었다. 본 연구의 이론과 실제 성과가 학계 및 교육 실무자들에게 참고가 되기를 기대해 본다. Non-Chinese speaking kindergarteners in Hong Kong are usually faced with huge difficulties in learning Chinese attributing to inadaquacy of resources, teaching materials, and experiences by kindergartens and their teachers. Desegregation between Chinese speaking and Non-Chinese speaking had been strongly advocated by the Equal Opportunities Commission for years, however, some new issues were created even with the best intention. To solve the above problem, the Hong Kong Jockey Club Charities Trust and institutions in collaboration designed intervention programmes, embedded with large scale research, in supporting non-Chinese speaking preschool education. Among the many intervention programmes, this study focused language learning theories and effective teaching. Research methods included on-site observation, video recording of lessons, interviews with principals and teachers, and children assessment of their language learning. aracters, the Liu shu and the Shuo wen chich tzu, and orthographic standardization. Language development of non-Chinese speaking kindergarteners was tracked longitudinally in each of their pre-school years that composed of four language assessments. Significant improvement of language learning results was observed during the three years, which proved the effects of learning theories and teaching practices. This study also consolidated ten language learning theories for the purpose of integration of Chinese speaking and non-Chinese speaking in the same classroom. Practical exemplars were also included. Educators could make ready use of them with minimum resources. This study aimed to share our theories as well as results of our practices with academics and practioners.

Numerical simulation of wind loading on roadside noise mitigation structures

TSE, K.T.,Yang, Yi,Shum, K.M.,Xie, Zhuangning Techno-Press 2013 Wind and Structures, An International Journal (WAS Vol.17 No.3

Numerical research on four typical configurations of noise mitigation structures and their characteristics of wind loads are reported in this paper. The turbulence model as well the model parameters, the modeling of the equilibrium atmospheric boundary layer, the mesh discretization etc., were carefully considered in the numerical model to improve the numerical accuracy. Also a numerical validation of one configuration with the wind tunnel test data was made. Through detailed analyses of the wind load characteristics with the inclined part and the wind incidence angle, it was found that the addition of an inclined part to a noise mitigation structure at-grade would affect the mean nett pressure coefficients on the vertical part, and that the extent of this effect depends on the length of the inclined part itself. The magnitudes of the mean nett pressure coefficients for both the vertical part and the inclined part of noise mitigation structure at-grade tended to increase with length of inclined part. Finally, a comparison with the wind load code British/European Standard BS EN 1991-1-4:2005 was made and the envelope of the mean nett pressure coefficients of the noise mitigation structures was given for design purposes. The current research should be helpful to improve current wind codes by providing more reasonable wind pressure coefficients for different configurations of noise mitigation structures.

Aims: Tenofovir alafenamide (TAF) is a novel prodrug that re-duces tenofovir plasma levels by 90% compared to tenofovir disoproxil fumarate (TDF), resulting in decreased bone mineral density (BMD) loss and renal toxicity. We aimed to study changes in BMD and markers of renal function of chronic hepatitis B (CHB) patients previously treated with TDF who were switched to TAF. Methods: This was a prospective single-arm open-label study of 75 CHB patients treated with TDF 300 mg daily who were switched to TAF 25 mg daily and followed for 24 weeks. All patients had been treated with TDF for at least 12 months and had HBV DNA < 21 IU/mL at the time of switch. BMD and markers of renal function were taken on the day of switch and repeated after 12 and 24 weeks of TAF treatment. Results: BMD significantly increased after switch from TDF to TAF from baseline to week 12 and remained stable at week 24. Mean percent changes from baseline to week 12 in hip and spine BMDs significantly increased (+ 12.9% and +2.4%, respectively). There were significantly more patients with gains in hip (86%) or spine (76%) BMD than patients who experienced loss (11% and 25%, respectively). No significant change in BMD was seen between week 12 and 24. There was no significant difference in eGFR_CG from baseline to week 24. Significant improvement was observed in urinary beta-2 micro globulin/creatinine ratio between baseline and week 12 that remained through week 24 (median change from baseline to week 12 and 24; 1.5, 1.0 and 1.1 mcg/g respectively; P<0.01). Similar changes were observed with retinol binding protein/creatinine ratio at from baseline to week 12 and 24 (median change from baseline to week 12 and 24; 1.7, 1.3 and 1.4 mcg/g respectively; P<0.01). There was significant increase in fractional excretion of phosphate from baseline to week 24 (11.9 to 14.0; P<0.05). Phosphate threshold for renal tubular reabsorption decreased from baseline to week 12 (2.8 to 2.6 mg/dL). Conclusions: Switching from long-term TDF to TAF among CHB patients was associated with significant improvement in BMD and some markers of proximal renal tubular function. There was no improvement in urinary phosphate handling after the switch which suggests TDF has a direct effect on bone metabolism that is reversible. Longer term and larger studies are needed to confirm these findings.

The Inconspicuous Acceleration in Qin Music: An Insider's View with Validation by a Perceptive Study

TSE.Chun-Yan 아시아음악학회 2007 Asian Musicology Vol.11 No.-

Qin, the musical instrument of the Chinese literati, is characterized by its subtle expressiveness. There is often a gradual acceleration of the tempo which is considered inconspicuous by insiders. To validate this inconspicuousness, a comparative perceptive study was done in an undergraduate music class. The students' impression on acceleration and their ability to identify correctly the tempo change of a section of a traditional qin piece and a traditional zheng piece (as control) were compared. Both pieces nearly doubled the tempo in the one minute section. Out of 16 students, 5 and 14 noted some acceleration, and 1 and 7 students measured the tempo change correctly, for the qin and zheng piece respectively (p value 0.004 and 0.07 respectively). The relative inconspicuousness of the acceleration in the qin piece is thus demonstrated. The psychoacoustic features of the inconspicuousness, the generalizability of the finding, and the aesthetic implications are analyzed.

Wind pressure characteristics for a double tower high-rise structure in a group of buildings

Tse, K.T.,Wang, D.Y.,Zhou, Y. Techno-Press 2013 Wind and Structures, An International Journal (WAS Vol.16 No.5

Wind pressure characteristics on a double tower high-rise structure, which is disturbed by surrounding buildings, were investigated using large eddy simulation (LES) and 1:300 scale wind tunnel experiments. The computational simulation technique and wind tunnel experimental technique were described in detail initially. Comparisons of computational results with the experimental data have subsequently been carried out to validate the reliability of LES. Comparisons have been performed in detail for the mean and fluctuating pressure coefficients. Detailed explanations of each comparison were given in the paper. To study further on the pressure coefficients on the building surfaces, parametric studies on shape coefficient and spatial correlation were performed and investigated. The numerical and experimental results presented in this paper advance understanding on wind field around buildings and the application of LES and wind tunnel tests.

Coping with China in Hard Times: Taiwan in Global and Domestic Aspects

Tse-Kang Leng 인하대학교 국제관계연구소 2011 Pacific Focus Vol.26 No.3

This paper argues that in the post-democratization era, the Taiwanese state devotes itself to create a comprehensive division of labor with China in favor of Taiwan. Both the DPP and KMT administrations have endeavored to re-intervene in fields like research and development to strengthen and upgrade industrial competitiveness. The Ma administration tries to adopt a policy of globalization with comprehensive engagements with China. However, political costs come with the efforts in deepening and institutionalizing such unique relationship. On the domestic front, the redistribution effect of the trade pact buttresses opposition forces to request a halt to further integration. To cope with the rise of China in hard times, the Taiwanese state chooses to adopt two-track policies to re-intervene into economic spheres of influence while searching for political compromise with China. From this aspect, the power of the Taiwanese state is not shrinking in the era of globalization. It requires more subtle ways to enhance capacities to co-exist with social forces in the domestic soil, and promote trust with major international players in the region. The state power is thus transformed and readjusted in a more complicated manner.
