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
THE MICROWAVE SPECTRUM OF 2-CARBAHEXABORANE(9)
No full textPresent address of C. S. Cheung; Jet Propulsion Laboratory, California Institute of Technology, Paskdena, California 91103.""Author Institution: University of Southern CaliforniaThe microwave spectrum of 2-Carbahexaborane(9) has been studied in the range 8--38 gHz. Transitions of eight isotopic species were assigned. Dipole moment and the boron framework structure were determined

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
