Convex functions on Grassmannian manifolds and Lawson–Osserman problem
No full textAbstractWe derive estimates of the Hessian of two smooth functions defined on Grassmannian manifold. Based on it, we can derive curvature estimates for minimal submanifolds in Euclidean space via Gauss map as in [Y.L. Xin, Ling Yang, Curvature estimates for minimal submanifolds of higher codimension, arXiv: 0709.3686; 24]. In this way, the result for Bernstein type theorem done by Jost and the first author could be improved
The historical review on the study of the insect pests of paddy in Taiwan till 1945
No full textThe present report is compiled in the purpose to introduce the work on the paddy insect pests in Taiwan till 1945, the cease of the Japanese occupied period. Although several fragmental records are found on some publications which compiled before 1895, almost scientific works are started since the establishment of Agricultural Experiment Station by Japanese. As till 1920’s, the Japanese goverment strenuously extends the production of paddy in Taiwan, many active works are done in this duration. At least, the faunal survey on the insect pest in the paddy field is almost finished till 1910’s. Through those works, 5 or 6 insect pests are recognized as the most destructive insect pests of paddy: (1) Paddy borer (Scirjxphaga incertulas), (2) Black rice bug (Scotinophara lurzida), (3) Rice leaf beetle (Oulema oryzae), (4) Rice spiny leaf beetle (Dactylispa armigera), (5) Brown rice planthopper (Nilaparvata lugens) or (6) White backed rice planthopper (Sogatella furcifera). Neverthiess, the scrutinized work in Taiwan is concentratedly done on paddy borer only. Since 1930’s, colonial policy by Japanese government changed to enforce the production of sugarcane and some horticultural crops, the experimental study on the paddy insect pests rather to be neglected. However, comparing with data in 1902 the rice production still increase about 4 times in 1940
Active Gust Load Alleviation for Flexible Wing Aircraft
No full textThis paper presents a novel active gust load alleviation approach within a multi-objective flight control framework developed by NASA for a flexible wing aircraft. The aircraft model is based on the NASA Generic Transport Model (GTM). The wing structures incorporate an aerodynamic control surface known as the Variable Camber Continuous Trailing Edge Flap (VCCTEF). Previous work already showed the ability of the VCCTEF to perform aeroelastic mode suppression, drag minimization and maneuver load alleviation in a multi-objective flight control framework. In this paper, the multi-objective flight control framework is extended to include active gust load alleviation. A Linear-Quadratic Gaussian (LQG) controller is augmented with Model Reference Adaptive Control (MRAC) to provide active gust load alleviation. Disturbance estimation is done using an Extended State Observer (ESO) to support the design of the active gust load alleviation controller. The results demonstrate the potential of active gust load alleviation within a multi-objective flight control framework for a high-aspect ratio flexible wing aircraft embodied with the VCCTEF.Aerospace EngineeringControl & Simulatio

An Investigation into the Authenticity of the Bi-Lin-Lang-Guan Version of Jin Lu-Xiang’s Shang Shu Zhu
No full text金履祥為宋、元之際經學大家，據載金氏關於《尚書》的作品有《尚書表注》一卷、《尚書注》十二卷，又嘗以《尚書》為主，旁採經子諸說，作《通鑑前編》十二卷。近人蔡根祥曾考證其十二卷《尚書注》，當是由《通鑑前編》中將關於《尚書》部份的文字輯出而成，乃後人偽作。不過，事實上今日傳世的金履祥《尚書注》有兩種版本，一為陸心源《十萬卷樓叢書》本，此為流行本，一本則收入清人方功惠《碧琳琅館叢書》當中。兩書內容完全不同，然大部份學者均未詳加分別，以為同本。本文試圖就此一發現發現，由既有文獻資料，整理關於金履祥《尚書注》的歷來著作情形，並對《碧琳琅館叢書》本《金氏尚書注》內容作詳細的探討。經研究後，發現此書的思想、內容均與金履祥時代不合，再進一步考察，得知此本亦是偽作，為後人取元人陳師凱《書蔡傳旁通》為主，並用及相關資料作為〈序〉、〈跋〉、〈附錄〉拼湊而成，當是清代中葉之後的人所偽作。Jin Lu-Xiang is an important scholar in the Sung and the Yuan Dynasties. Allegedly, he is the author of Shang Shu Biao Zhu (Commentaries on the Chronicle in Shang Shu), Shang Shu Zhu (Commentaries on Shang Shu), and Zi Zhi Tong Jian Qian Bian (The History before Zi Zhi Tong Jian). Recently, Tsai Ken-Hsian has found out that Shang Shu Zhu is a fake: it is actually a part of Zi Zhi Tong Jian Qian Bian.
We currently have 2 versions of Jin’s Shang Shu Zhu, one of which is in Lu Xin-Yuan’s Shi-Wan-Juan-Lou Series and the other one is in Fang Gong-Hui’s Bi-Ling-Lang-Guan Series. These 2 versions are totally different, but few scholars have discovered this fact.
With a detailed investigation into all the documents related to Jin’s writing process of Shang Shu Zhu, this study proves that the Bi-Ling-Lang-Guan version is also a fake, because the thoughts that it includes do not exist in Jin’s time. This version is actually Chen Shi-Kai’s Shu Tsai Zhuan Pang Tong in the Yuan Dynasty, combined with related information as its preface, postscript, and appendix. It has been fabricated in the middle period of the Qing Dynasty

This Can Be Discouraging: The Overplaying of Impression Management
No full textDrawing on self-protection, self-enhancement, and conservation of resources (COR) theory, this study examines how employees\ue2 emotional labor, surface acting and deep acting, leads to supervisors\ue2 abusive supervision. In addition, this research examines the role of impression management as a mediating mechanism. To prove the hypotheses, 259 full-time working adults from a variety of industries were surveyed. Consistent with the predictions of self-protection, self-enhancement, and COR theory, the results show that whether employees adopt surface or deep acting, they will further do impression management, while those emotional regulation strategies eventually lead to supervisors\ue2 abusive supervision behaviors. The findings also provide the support that impression management plays a mediating role in the relationship between emotional labor and abusive supervision
