Description
Wu Yun (d. 778) was prominent poet at the Tang court. His biography of the Daoist ritualist Lu Xiujing (406-77) can be read on several levels. It functions as a source of information on Lu's life and works, but a reading focused on this alone is insufficient. Conventions of Chinese biography dictate the text is read not just with an eye towards who Lu "really was," but also how he functions as a character fashioned by an author for certain purposes. With this in mind, the reader can learn not just about Lu, but about the audience of the text and the aims of its author. Lu functioned as a model for later Daoist masters and as an exhortation to proper conduct towards them on the part of rulers and elites. Finally, with reference to the work of Michel Foucault and scholars of collective memory, this work can be read as a window onto the world of discourse in early medieval China.

Description
Efficiency of components is an ever increasing area of importance to portable applications, where a finite battery means finite operating time. Higher efficiency devices need to be designed that don't compromise on the performance that the consumer has come to expect. Class D amplifiers deliver on the goal of increased efficiency, but at the cost of distortion. Class AB amplifiers have low efficiency, but high linearity. By modulating the supply voltage of a Class AB amplifier to make a Class H amplifier, the efficiency can increase while still maintaining the Class AB level of linearity. A 92dB Power Supply Rejection Ratio (PSRR) Class AB amplifier and a Class H amplifier were designed in a 0.24um process for portable audio applications. Using a multiphase buck converter increased the efficiency of the Class H amplifier while still maintaining a fast response time to respond to audio frequencies. The Class H amplifier had an efficiency above the Class AB amplifier by 5-7% from 5-30mW of output power without affecting the total harmonic distortion (THD) at the design specifications. The Class H amplifier design met all design specifications and showed performance comparable to the designed Class AB amplifier across 1kHz-20kHz and 0.01mW-30mW. The Class H design was able to output 30mW into 16Ohms without any increase in THD. This design shows that Class H amplifiers merit more research into their potential for increasing efficiency of audio amplifiers and that even simple designs can give significant increases in efficiency without compromising linearity.

Description
Class D Amplifiers are widely used in portable systems such as mobile phones to achieve high efficiency. The demands of portable electronics for low power consumption to extend battery life and reduce heat dissipation mandate efficient, high-performance audio amplifiers. The high efficiency of Class D amplifiers (CDAs) makes them particularly attractive for portable applications. The Digital class D amplifier is an interesting solution to increase the efficiency of embedded systems. However, this solution is not good enough in terms of PWM stage linearity and power supply rejection. An efficient control is needed to correct the error sources in order to get a high fidelity sound quality in the whole audio range of frequencies. A fundamental analysis on various error sources due to non idealities in the power stage have been discussed here with key focus on Power supply perturbations driving the Power stage of a Class D Audio Amplifier. Two types of closed loop Digital Class D architecture for PSRR improvement have been proposed and modeled. Double sided uniform sampling modulation has been used. One of the architecture uses feedback around the power stage and the second architecture uses feedback into digital domain. Simulation & experimental results confirm that the closed loop PSRR & PS-IMD improve by around 30-40 dB and 25 dB respectively.

Description
A Japanese national identity is generally thought to have originated in the 17th century, with the advent of the Kokugaku movement. I will argue that there is earlier evidence for the existence of a Japanese national identity in the Kumano Nachi mandalas of the Kamakura and Muromachi periods. These mandalas employ the Nachi waterfall as a symbol of the strength and power of the Japanese land, counterbalancing Chinese Buddhist visual motifs. In this paper, I further assert that these mandalas are an early example of an artistic tradition of painting specific landscape features as symbols of a Japanese national identity, and that this tradition continues into the modern period.

Description
This thesis examines the relationship between political culture, Confucian intellectuals, and the rise of a new intellectual and cultural paradigm during the early to mid-Ming dynasty (1368 – 1644). The main goal of this thesis is to supplement current scholarship on Chen Xianzhang’s 陳獻章 (1428 – 1500) life as an intellectual of Cantonese origin and his political activities at both local and national levels. Furthermore, the thesis supplements current research on the Yangming School and the School’s contribution to the revitalization of private academies during the Ming with a study on the relationship between the three Confucian intellectuals enshrined in 1584 and the revival of private academies from the perspective of political history. In analyzing the relationship between these various aspects of the Ming political and intellectual landscapes, the thesis uses the 1584 Confucian Temple enshrinement, which involved Wang Yangming 王陽明 (1472 – 1529) and his two older contemporary Confucian intellectuals, Chen Xianzhang and Hu Juren 胡居仁 (1434 – 1484), as an entry point to explore the dynamics behind the political and cultural changes at the time. It aims to investigate the issue of cultural power versus imperial power, the central-versus-peripheral narrative in Ming politics, the evolution of how cultural power was asserted by members of the Confucian tradition, and the manifestation of such evolution in response to contemporary political discussions. The author begins with an analysis of the revival of private academies (shuyuan 書院) during the mid-Ming, and the influence of Chen Xianzhang and Hu Juren in this revival. He then dissects the relationship between the revival of private academies and the emergence of jianghui 講會 (discussion gatherings) in the following decades. Finally, the thesis discusses the struggle of mid-Ming intellectuals in gaining cultural legitimization for both private academies and jianghui activities by urging the imperial court to give due recognition through enshrining Wang, Chen, and Hu in the Confucian Temple, and the historical significance of this struggle to the development of the Confucian tradition in the Ming. The author ultimately argues that Chen Xianzhang, contrary to the common perception about him being a philosopher-poet who was indifferent to political discourses, was in fact a politically active intellectual; and that Chen’s contributions to the revival of private academies in Guangdong predated that of Wang Yangming in the Jiangnan region.

Description
In this thesis, a digital input class D audio amplifier system which has the ability
to reject the power supply noise and nonlinearly of the output stage is presented. The main digital class D feed-forward path is using the fully-digital sigma-delta PWM open loop topology. Feedback loop is used to suppress the power supply noise and harmonic distortions. The design is using global foundry 0.18um technology.
Based on simulation, the power supply rejection at 200Hz is about -49dB with
81dB dynamic range and -70dB THD+N. The full scale output power can reach as high as 27mW and still keep minimum -68dB THD+N. The system efficiency at full scale is about 82%.

Description
Sacred apocalyptic texts claim to foretell coming events, warning the faithful of some terrible fate that lies beyond the present. Such texts often derive their power from successfully recasting past events in such a way as they appear to be "predicted" by the text and thus take on additional meanings beyond the superficial. This ex eventu status allows apocalyptic texts to increase the credibility of their future predictions and connect emotionally with the reader by playing on present fears. The fifth-century Daoist apocalyptic text, the Scripture on the Cycles of Heaven and Earth (Tiandi yundu jing, 天地運度經), is no exception. This thesis examines the apocalyptic markers in the poetic sections of the text, attempting to develop a strategy for separating the generic imagery (both to Chinese texts and the apocalyptic literary genre as a whole) from the more significant recoverable references to contemporary events such as the fall of the Jin dynasty and the subsequent founding of the Liu-Song dynasty.

Description
The Hong Kong-born Canadian photographer and performance artist Tseng Kwong Chi mostly worked in the United States until the year he died in 1990. Upon arriving in New York in 1979, he started his career with a new name. By dropping his anglicized name Joseph and replacing it with his Chinese given name Kwong Chi, Tseng made a clear statement: this is my staged persona who refuses to assimilate to Western culture. This thesis deconstructs Tseng’s key works, including his party-crashing Met series, the decade-long East Meets West series, and the extended Expeditionary series. With his persona disguised by wearing a Mao suit and a pair of sunglasses, I argue that Tseng was a pioneer in the genre of Asian American performance photography and that his work foreshadowed the cultural jamming movement in his innovative use of détournement while it also critically comments on orientalism, cultural fetish, and Asian identity politics. Additionally, Tseng’s work served as a bridge, connecting art history with issues of Asian American identity. As a gay artist who worked mostly in the United States, his work was an early example of what Jachinson Chan has suggested as an alternative model of masculinity for Asian American men: that Asian American men can be free, independent, expressive, and willing to embrace femininity with their masculinity. As David Eng has argued, Tseng also bridged the fields of Asian American queer studies and diaspora studies. Moreover, Tseng carried the legacy of the first-generation Chinese American artists in the medium of photography and inspired the next generation of diasporic artists to explore Asian identity, and to contest the image of Mao and the power dynamics between East and West.

Description
This thesis hopes to propose a new hypothesis about the origin of Chinese heptasyllabic poetry. Although there are numerous academic discussions in the existing poetic narrative, few of them have noticed the possible effect of the Celestial Master Daoism. Based on the literary analysis and formal comparison, this thesis first finds that, during the time Cao Pi曹丕 created his “Yange xing,” the first literati heptasyllabic poem, “cypress beam genre” (boliang ti柏梁體) poetry – the earliest form of heptasyllabic poetry – was already a normal, fixed, and mature poetic form within the community of Celestial Master Daoism. Therefore, Celestial Master Daoism’s mastery of boliang ti poetry and their intensive and frequent composition highly likely motivated Cao Pi, the new Wei ruler who took over the populace of Celestial Master Daoism and had a close relationship with Zhang Lu’s張魯 family, to learn and introduce this poetic form into his own poetic creation. Then, this thesis also traces this poetic form back to suburban sacrifice songs in the Han dynasty. During the reign of Emperor Wu, the prototype of boliang ti poetry appeared in suburban sacrifice songs created to express worship to heavenly and earthly deities. Hence, when the Celestial Master Daoism became the inheritor of regional power (mainly in Sichuan, Chongqing, and Shaanxi of today’s China) of the Han empire and hoped to establish their own regime, they created their own ritual texts by modeling after Han suburban sacrifice songs. In so doing, they demonstrated their legitimacy and exclusivity by connecting the regime itself with Dao.

Description
This thesis is a translation and analysis of the “Epitaph of the Wu Kingdom
Transcendent Duke Ge of the Left Palace of the Grand Bourne” (Epitaph below). The author was Tao Hongjing (456 CE-536 CE). The subject of this Epitaph inscribed on a stele was Ge Xuan (trad. 164 CE-244 CE). Ge Xuan had two titles attributed to him by later Daoists. According to the Lingbao scriptures, Ge was appointed by the Perfected of Grand Bourne, a heavenly title. Later, in the Shangqing scriptures, Ge Xuan was said to be an earthly transcendent without any heavenly appointment. This debate occurred before Tao Hongjing began to write. This stele epitaph is essential, as it records sayings from both Lingbao and Shangqing scriptures. By reading this translated epitaph, scholars can know more about different versions of Ge Xuan's legend, as well as how Ge Xuan's legend was constantly rewritten by later Daoists.
