Niu (紐) in Early Medieval China from the Perspectives of Chinese Historical Phonology and Versification
No full textThe Recent Style Prosody, consisting of the binary opposition of the level (ping, 平) and deflected (ze, 仄) tones, has gained a prominent position amongst the study of versification. Yet the origins of the bifurcation of the four tones and the imposition of tonal rules on couplets remain unknown to scholars. This dissertation attempts to examine the origins and reception of prosodic and phonological terms adopted from the 4th to 9th centuries, with the aid of Siddham and Sanskrit corpuses. This paper provides a detailed explanation on the possible origin and development of Niu (紐), a significant term adopted in the realms of Chinese Historical Phonology and Versification, particularly "Eight Defects" (八病) mentioned in Bunkyôhifuron. The three Definitions of Zhengniu (正紐) Pangniu (傍紐) found in Bunkyôhifuron should be regarded as a late development, whereas the pseudo equivalent Daniu (大紐) and Xiaoniu (小紐) correspond to an earlier usage usually attributed to Shen Yue. Through a careful examination of Sanskrit texts, the author has come to the conclusion that Mair and Mei's identification of Niu with bandha (pattern poetry) is questionable; on the contrary, Niu is an exact counterpart of the term yamaka (repetition of syllables) in Sanskrit Poetics. As opposed to Sanskrit corpus which treats yamaka as euphony (śabdālamkāra), the Pāli Text Subodhālankāra shares common features with the "Eight Defects" that regard Niu as a prosodic defect (dosa). It is reasonable to argue that the concept of yamaka was borrowed from a Prakrit secular tradition other than Classical Sanskrit Poetics
Online Iterative Adaptive Dynamic Programming Approach for Solving the Zero-Sum Game for Nonlinear Continuous-Time Systems with Partially Unknown Dynamics
No full textThe current study presents an online iterative adaptive dynamic programming approach to resolve the zero-sum game (ZSG) for nonlinear continuous-time (CT) systems containing a partially unknown dynamic. The Hamilton-Jacobian-Issacs (HJI) equation is solved along the state trajectory according to the value function approximation and the policy improvement online. Relaxed dynamic programming is utilized to ensure the algorithm’s convergence. Model and costate networks were established to conduct the method. Computational simulations are performed to present the efficiency of the algorithm.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.Control & Simulatio

Formation Control of Skid-Steered Vehicles Based on Distributed Model Predictive Control
No full textThe skid-steered vehicle has the advantages of simple structure and strong maneuverability. Its formation driving can effectively improve safety, reduce energy consumption and exert its benefits, and has wide application prospects in military and civilian fields. Differential skid steering has strong horizontal and vertical coupling characteristics, so the tracking performance of the vehicle is poor. Therefore, it is of great significance to study horizontal and vertical joint control. Firstly, the mathematical model of the vehicle platoon is established to realize the formation control of skid-steered vehicles. Then, a combined horizontal and vertical control strategy for skid-steered vehicle formation is proposed, and a distributed model predictive controller is designed. Finally, simulation experiments verified that the designed method has good feasibility and stability.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.Transport and Plannin
On tracial approximation
No full textAbstractLet C be a class of unital C*-algebras. The class TAC of C*-algebras which can be tracially approximated (in the Egorov-like sense first considered by Lin) by the C*-algebras in C is studied (Lin considered the case that C consists of finite-dimensional C*-algebras or the tensor products of such with C([0,1])). In particular, the question is considered whether, for any simple separable A∈TAC, there is a C*-algebra B which is a simple inductive limit of certain basic homogeneous C*-algebras together with C*-algebras in C, such that the Elliott invariant of A is isomorphic to the Elliott invariant of B. An interesting case of this question is answered. In the final part of the paper, the question is also considered which properties of C*-algebras are inherited by tracial approximation. (Results of this kind are obtained which are used in the proof of the main theorem of the paper, and also in the proof of the classification theorem of the second author given in [Z. Niu, A classification of tracially approximately splitting tree algebra, in preparation] and [Z. Niu, A classification of certain tracially approximately subhomogeneous C*-algebras, PhD thesis, University of Toronto, 2005]—which also uses the main result of the present paper.
Fei-yen wai-zhuan the true era of its birth and investigation of its author
No full textFei-yen wai-zhuan 飛燕外傳 (The Unofficial Biography of [Zhao] Fei-yen) is one of the classical-language fictions in traditional China, describing the famous romance between Emperor Cheng-di 成帝 and Zhao Fei-yen 趙飛燕 sisters in the Former Han Dynasty. The author is attributed with Ling Xüan 伶玄, who definitely had confessed that he was living with the Former Han Dynasty in his brief autobiography. However, it was too suspicious to believe, from the beginning of its appearance in the Southern Song Dynasty, scholars have been puzzled to determine the true era of its birth. Through their discussions, now it is widely accepted that Fei-yen wai-zhuan was born during the Six Dynasties, not in the Tang Dynasty, though it is still lacking in conclusive evidence. But some insist that it could be compared with the great masterpieces of Tang-tales, like Ying-ying zhuan 鶯鶯傳, Li Wa zhuan 李娃傳, Huo Xiao-yü zhuan 霍小玉傳, which belonged to the Tang Dynasty. Then should we say that Fei-yen wai-zhuan was a premature masterpiece? It still remains a great mystery to all, including its author Ling Xüan himself. This study, paying attention to the text itself, proves this tale should belong to the Tang Dynasty. Its main keywords are two, Zhen-la 眞臘 and Qi-chu Ling-hua jing 七出菱花鏡 (Water-chestnut flower shaped bronze mirror, circled by seven petals). The former, used first in the historical records in China was in the Sui Dynasty Da-ye 大業 12years(616), and the latter one likely appeared after reign of Empress Wu(690--705). These facts simply tell us Fei-yen wai-zhuan was born in the Tang Dynasty. The true author of this tale is Niu Seng-ru 牛僧孺, a famous prime minister of late Tang and was also a well-known writer of Tang-tales, who authored Xüan-guai lu 玄怪錄. We could know the close affinities between Fei-yen wai-zhuan and Xüan-guai lu. As a drafted scholar-official, all of Niu's life had been under the strife in bureaucracy with the factional parties at that time. Once the opposition party blamed Niu for violating his majesty, to write the tale Zhou Qin xing-ji 周秦行記 named Niu Seng-ru. Though its writer was anonymous, Niu was nearly accused of injury to the majesy (Lèse majesté). I contend Niu decided to write Fei-yen wai-zhuan under a pseudonym to make counterattack against a recreant writer in the same manner and to regain true pride for himself

No full textAbstract
Date Presented 3/30/2017
We examined to what extent high waist circumference was linked with decreased functional mobility over 4 yr in adults with knee osteoarthritis (OA). Measuring waist circumference may better stratify the risk of decreased functional mobility among adults with obesity and knee OA.
