A Review of silicon carbide development in MEMS applications
No full textDue to its desirable material properties, Silicon Carbide (SiC) hasbecome an alternative material to replace Si for MicroelectromechanicalSystems (MEMS) applications in harsh environments. To promote SiC MEMSdevelopment towards future cost-effective products, main technology areas inmaterial deposition and processes have attracted significant interest. Thedevelopments in these areas have contributed to the rapid emergence of SiCMEMS prototypes. In this paper, we give an overview of the importantdevelopments in SiC material formation and fabrication processes in recentyears. Some of the most interesting state-of-the-art SiC MEMS devices arereviewed. This highlights the major progresses in SiC MEMS developed thusfar. This paper also looks into the prospect of SiC MEMS drawing attention topotential issues
Some Weighted Hardy-type Inequalities of Vector-Valued Functions
No full textBy adopting the C-technique of Cheung and Pečrić, we establish some interesting weighted Hardy-type inequalities of vector-valued functions. These generalize and improve some existing results of Cheung, Cheung-Hanjš-Pēcarić, Hanjš-Love-Pečarić, Levinson, and Pachpatte. [ABSTRACT FROM AUTHOR
Correlation Between Structure Of Solidification And Resulting Properties [correlaç̃o Entre Estrutura De Solidificação E Propriedades Decorrentes]
No full textSolidification is a critical processing route for metals and alloys. The importance of solidification processing in metallurgical operations is emphasized in this article, as the metallurgical structure, distribution of porosity, micro and macrosegregation, as well as the mechanical properties of cast products are intimately associated with the solidification phenomena.60550694697Garcia, A., (2001) Solidificação - Fundamentos E Aplicações, , www.editora.unicamp.br, Editora da UnicampSiqueira, C., Cheung, N., Garcia, A., Solidification thermal parameters affecting the columnar to equiaxed transition (2002) Metallurgical and Materials Transactions A, 33 A, pp. 2107-2118Ferreira, I.L., Santos, C.A., Voller, V.R., Garcia, A., Analytical, numerical, and experimen tal analysis of inverse macrosegregation during upward unidirectional solidification of Al-Cu alloys (2004) Metallurgical and Materials Transactions B, 35 B, pp. 285-297Quaresma, J.M.V., Santos, C.A., Garcia, A., Correlation between unsteady-state solidification conditions, dendrite spacings, and mechanical properties of Al-Cu alloys (2000) Metallurgical and Materials Transactions A, 31 A, pp. 3167-317
New Hong Kong Cinema: transitions to becoming Chinese in 21st-century East Asia
No full textThe trajectory of Hong Kong films had been drastically affected long before the city’s official sovereignty transfer from the British to the Chinese in 1997. The change in course has become more visible in recent years as China has aggressively developed its national film industry and assumed the role of powerhouse in East Asia’s cinematic landscape. The author introduces the 'Cinema of Transitions' to study the New Hong Kong Cinema and on- and off-screen life against this background. Using examples from the 1980s to the present, this book offers a fresh perspective on how Hong Kong-related Chinese-language films, filmmakers, audiences, and the workings of film business in East Asia have become major platforms on which 'transitions' are negotiated
Steve Dutton, Percy Peacock, Steve Swindells : Entropic Gym
No full textIn the pamphlet for their exhibition with Peacock, Dutton and Swindells describe a performance where they visited castles in England and threw texts from the ramparts. Cheung argues that the operation of their installation remains incomplete without a viewer to re-experience it. Biographical notes
