Wang Meng and contemporary Chinese literature: the vicissitudes of a committed writer
No full textThis thesis examines the way Wang Meng has developed as a writer from the 1950s to the 1990s in the context of New China's political and literary background. It looks at the compromises he was forced to make between his political beliefs in the Communist Party and his chosen role as a professional writer. After his disastrous early foray into what was deemed to be unacceptable political criticism with The Young Newcomer in the Organisation Department in the 1950s, when the opportunity came to start publishing again in the late 1970s he was boldly innovative in style, helping to transform New Period literature, but conservative in content, sticking to politically acceptable topics. It was only with Hard Porridge in 1989 that he ventured again, and very successfully, into political comment. There is no outstanding leading writer in contemporary China, but Wang Meng is a leading contender for the title
The physics of H-Darrieus turbine starting behavior
No full textThis paper provides a resolution to the contradictory accounts of whether or not the Darrieus turbine can self-start. The paper builds on previous work proposing an analogy between the aerofoil in Darrieus motion and flapping-wing flow mechanisms. This analogy suggests that unsteadiness could be exploited to generate additional thrust and that this unsteady thrust generation is governed by rotor geometry. Rotors which do not exploit this unsteadiness will not self-start.
To confirm the hypothesis, unsteady effects were measured and then incorporated into a time-stepping rotor analysis and compared to experimental data for self starting wind turbines. When unsteady effects were included the model was able to predict the correct starting behaviour.
The fundamental physics of starting were also studied and parameters that govern the generation of unsteady thrust were explored: namely chord-to-diameter and blade aspect ratios. Further simulation showed that the Darrieus rotor is prone to be locked in a deadband where the thrust is not continuous around a blade rotation. This discrete thrust is caused by the large variation of incidence angle during start-up making the Darrieus blade ineffective during part of the rotation.
The results show that unsteady thrust can be promoted through an appropriate selection of blade aspect and chord-to-diameter ratios, therefore self-starting rotors may be designed. A new definition of self-starting is also proposed
Migrant workers, collaborative research and spatial pressures : an interview with Meng Yue
No full textIn July last year I had the opportunity to interview Meng Yue, literary scholar and author of Shanghai and the Edges of Empire (2006). Meng Yue has been collaborating with Toronto-based architect and artist Adrian Blackwell for a number of years, with their students from literature and architecture undertaking highly interesting research on the peripheral zones of Beijing. Questions of peri-urban food production, land use, resource distribution and the multiplication of labour skills have framed these investigations. The interview below is extracted from a considerably longer discussion we had in Beijing during the late summer of 2007, half of which was lost to the faulty battery of an ipod (the rest remains to be transcribed from video…)

Sequels to honglou meng : how gu taiqing continues the story in honglou meng ying
No full textAfter Honglou meng (1791) was published, a number of sequels appeared that redefined its major characters, rewrote its ending, and continued the story of life within the two Jia households. One of these was Honglou meng ying (1877), by female poet, Gu Taiqing. Despite its status as the earliest extant novel written by a woman, few studies have been devoted to examining it. Building on research that Ellen Widmer has provided on Gu Taiqing and her work, including Honglou meng ying, I will explore the novel further in terms of its relationship to the parent work and to other sequels written by men, and also examine it on its own terms as a literary work. Some of the main questions that I will address include: how does it compare to other sequels to Honglou meng? How does Gu Taiqing’s continuation of Honglou meng depart from the parent novel? I have organized my discussion by providing an introduction to Gu Taiqing, whilst providing contextual information about women’s education, their relationship to fiction, and the impact of Honglou meng. Chapter One will deal with the broad issue of sequels in the Chinese context, the popularity of writing sequels during the Ming and Qing dynasties, and conclude with some observations about Honglou meng sequels in particular. The second chapter will deal exclusively with Gu Taiqing’s Honglou meng ying, evaluating it in terms of how the author continues the parent work, how she refashions its characters and themes, and how her sequel reflects her own unique concerns (which may not have been part of the original parent work). Finally, I will conclude with some remarks about Honglou meng ying in terms of its relation to sequel writing in late imperial China and its contribution to our understanding of women’s reading and writing in the final years of the Qing dynasty.Arts, Faculty ofAsian Studies, Department ofGraduat
Composition measurements of crude oil and process water emulsions using thick-film ultrasonic transducers
No full textThis paper presents an experimental study to investigate the suitability of thick-film ultrasonic transducers for composition measurements in heterogeneous mixtures. Following on from earlier developments [G. Meng, A.J. Jaworski, T. Dyakowski, J.M. Hale, N.M. White, Design and testing of a thick-film dual-modality sensor for composition measurements in heterogeneous mixtures, Meas. Sci. Technol. 16(4) (2005) 942–954], focused on the design and preliminary testing of the transducers for mixtures of vegetable oil and salty water, the current paper looks in more detail into their application to industrially relevant fluids, namely crude oil and process water, which are common in oil and gas extraction and petrochemical industries. The measurements are based on the time-of-flight of the ultrasonic pressure wave in order to obtain the speed of sound. The results, showing the variation of the speed of sound with the volume fraction of crude oil, for three different temperatures, are compared with five theoretical models available in the existing literature. It is shown that the models proposed by Urick [R.J. Urick, A sound velocity method for determining the compressibility of finely divided substances, J. Appl. Phys. 18 (1947) 983–987] and by Kuster and Toks¨oz [G.T. Kuster, M.N. Toks¨oz, Velocity and attenuation of seismic waves in two-phase media. Part I. Theoretical formulations, Geophysics 39 (1974) 587–606] provide a relatively accurate prediction for the speed of sound in the media studied. Interestingly, the model developed by Povey and co-workers [V.J. Pinfield, M.J.W. Povey, Thermal scattering must be accounted for in the determination of adiabatic compressibility, J. Phys. Chem. B 101 (1997) 1110–1112] only agrees with experiment when its thermal scattering features are neglected. Overall, the results obtained demonstrate that the slim-line and compact thick-film transducers can be considered as a viable means for the composition measurements in the process conditions
