Impacts of FDI Renewable Energy Technology Spillover on China's Energy Industry Performance

Environmental friendly renewable energy plays an indispensable role in energy industry development. Foreign direct investment (FDI) in advanced renewable energy technology spillover is promising to improve technological capability and promote China’s energy industry performance growth. In this paper, the impacts of FDI renewable energy technology spillover on China’s energy industry performance are analyzed based on theoretical and empirical studies. Firstly, three hypotheses are proposed to illustrate the relationships between FDI renewable energy technology spillover and three energy industry performances including economic, environmental, and innovative performances. To verify the hypotheses, techniques including factor analysis and data envelopment analysis (DEA) are employed to quantify the FDI renewable energy technology spillover and the energy industry performance of China, respectively. Furthermore, a panel data regression model is proposed to measure the impacts of FDI renewable energy technology spillover on China’s energy industry performance. Finally, energy industries of 30 different provinces in China based on the yearbook data from 2005 to 2011 are comparatively analyzed for evaluating the impacts through the empirical research. The results demonstrate that FDI renewable energy technology spillover has positive impacts on China’s energy industry performance. It can also be found that the technology spillover effects are more obvious in economic and technological developed regions. Finally, four suggestions are provided to enhance energy industry performance and promote renewable energy technology spillover in China.

Participatory Sonic Arts: towards a socially engaged art of sound in the everyday (The Som da Maré Project)

Participatory and socially engaged art practices have, for a couple of decades, emerged a myriad of aesthetic and methodological strategies across different media. These are artistic practices that have a primary interest in participation, affecting social dynamics, dialogue and at times political activism. Nato Thompson in “Living Form: Socially Engaged Art from 1991-2011” surveys these
practices, which range from theatre to urban planning, visual art to healthcare. Linked to notions such as relational aesthetics (Bourriaud, 1998), community art and public art, socially engaged art often focuses on the development of a sense of ownership by the part of participants. If an artist is working truly collaboratively with participants and addressing the reality of a particular community, the long-term effect of a project lies in the process of engagement as well as in the artwork itself. Projects by New York based artist Pablo Helguera, for example, use different media to engage with social inequalities through participative action while rejecting the notion of art for art sake.

“Socially engaged art functions by attaching itself to subjects and problems that normally belong to other disciplines, moving them temporarily into a space of ambiguity. It is this temporary snatching away of subjects into the realm of art-making that brings new insights to a particular problem or condition and in turn makes it visible to other disciplines.” (Helguera, 2011)

Socially engaged practices develop the notion of artwork about or by a community, to work of a community. In this chapter we address how socially engaged, participatory approaches can form a context for the sonic arts, arguably less explored than practices such as theatre and performance art. The use of sound is clearly present in a wide range of socially engaged work (e.g. Helguera’s “Aelia Media” enabling a nomadic radio station in Bologna or Maria Andueza “Immigrant Sounds – Res(on)Art (Stockholm)” exploring ways of sonically resonating a city, or Sue MacCauley’s “The Housing Project” addressing ways of representing the views of urban dwellers on public scape through sound art. It is nevertheless rare to encounter projects which take our experience of sound in the everyday as a trigger for community social engagement in a participatory context.
We address concepts and methodologies behind the project Som da Maré, a participatory sonic arts project in the favelas of Maré, Rio de Janeiro.

The Representation of the Female Body in the Multimedia Works of Regina José Galindo

The female body is central to the performance art, poetry and blog site interventions of Guatemalan Regina José Galindo. While Galindo is best known for her performance work, this article compares the hereto overlooked, distinctive and often shocking representations of the female body across her multimedia outputs. We first consider the ways in which, in all three media, Galindo presents an ‘excessive’, carnivalised, grotesque and abject female body. Second, we analyse representations of the female body that has been subjected to violence at a private and public level. In so doing, we show how Galindo not only contests hegemonic visions of gender and (national) identity but also challenges the viewer/reader to engage with, rather than look away from, the violence to which women are subjected in patriarchal society.

The Queen's Shilling:A collaboration with Goldin+Senneby

A performance art piece in the Centre for Contemporary Art, Derry/Londonderry as part of the City of Culture. International conceptual artists Goldin+Senneby commissioned me to write a short play inspired by their obsessions with alchemy, royalty and the financial markets. The play dramatises the suffering of Queen Elizabeth II as she confronts her own mortality in a world where she is an immortal symbol. Through a conversation with her predecessor Elizabeth I, she reveals that the whole stability of the financial system rests on the weight of her daily effluvia.

Investigation of the effects of flow conditions at rotor inlet on mixed flow turbine performance for automotive applications

Current trends in the automotive industry have placed increased importance on engine downsizing for passenger vehicles. Engine downsizing often results in reduced power output and turbochargers have been relied upon to restore the power output and maintain drivability. As improved power output is required across a wide range of engine operating conditions, it is necessary for the turbocharger to operate effectively at both design and off-design conditions. One off-design condition of considerable importance for turbocharger turbines is low velocity ratio operation, which refers to the combination of high exhaust gas velocity and low turbine rotational speed. Conventional radial flow turbines are constrained to achieve peak efficiency at the relatively high velocity ratio of 0.7, due the requirement to maintain a zero inlet blade angle for structural reasons. Several methods exist to potentially shift turbine peak efficiency to lower velocity ratios. One method is to utilize a mixed flow turbine as an alternative to a radial flow turbine. In addition to radial and circumferential components, the flow entering a mixed flow turbine also has an axial component. This allows the flow to experience a non-zero inlet blade angle, potentially shifting peak efficiency to a lower velocity ratio when compared to an equivalent radial flow turbine.
This study examined the effects of varying the flow conditions at the inlet to a mixed flow turbine and evaluated the subsequent impact on performance. The primary parameters examined were average inlet flow angle, the spanwise distribution of flow angle across the inlet and inlet flow cone angle. The results have indicated that the inlet flow angle significantly influenced the degree of reaction across the rotor and the turbine efficiency. The rotor studied was a custom in-house design based on a state-of-the-art radial flow turbine design. A numerical approach was used as the basis for this investigation and the numerical model has been validated against experimental data obtained from the cold flow turbine test rig at Queen’s University Belfast. The results of the study have provided a useful insight into how the flow conditions at rotor inlet influence the performance of a mixed flow turbine.

Performance analysis of a feasible air-cycle refrigeration system for road transport

The performance of an air-cycle refrigeration unit for road transport, which had been previously reported, was analysed in detail and compared with the original design model and an equivalent Thermo King SL200 vapour-cycle refrigeration unit. Poor heat exchanger performance was found to be the major contributor to low coefficient of performance values. Using state-of-the-art, but achievable performance levels for turbomachinery and heat exchangers, the performance of an optimised air-cycle refrigeration unit for the same application was predicted. The power requirement of the optimised air-cycle unit was 7% greater than the equivalent vapour-cycle unit at full-load operation. However, at part-load operation the air-cycle unit was estimated to absorb 35% less power than the vapour-cycle unit. The analysis demonstrated that the air-cycle system could potentially match the overall fuel consumption of the vapour-cycle transport refrigeration unit, while delivering the benefit of a completely refrigerant free system.

Transmission line matching effects on the performance of shunt-C/series-tuned and series-L/parallel-tuned Class-E amplifiers

The impact that the transmission-line load-network has on the performance of the recently introduced series-L/parallel-tuned Class-E amplifier and the classic shunt-C/series-tuned configuration when compared to optimally derived lumped load networks is discussed. In addition an improved load topology which facilitates harmonic suppression of up to 5 order as required for maximum Class-E efficiency as well as load resistance transformation and a design procedure involving the use of Kuroda's identity and Richard's transformation enable a distributed synthesis process which dispenses with the need for iterative tuning as previously required in order to achieve optimum Class-E operation. © 2005 IEEE.
