OBJECTIVE To discuss our experiences with the use of a supratip transposition flap to simultaneously correct pollybeak deformity and nasal tip dimpling. DESIGN From April 1, 2007, through August 31, 2008, 10 Asian women with a contracted, short nose that exhibited nasal tip dimpling were retrospectively included in this study. By use of an open approach, the osteocartilaginous framework was e...

In vivo insertion experiments are essential to optimize novel neural implants. Our work focuses on the interaction between intact dura mater of rats and as-fabricated single-shaft silicon microprobes realized by deep reactive ion etching. Implantation parameters like penetration force and dimpling through intact dura mater were studied as a function of insertion speed, microprobe cross-section,...

this paper addresses the problem of the fractional sliding mode control (fsmc) for a mems optical switch. the proposed scheme utilizes a fractional sliding surface to describe dynamic behavior of the system in the sliding mode stage. after a comparison with the classical integer-order counterpart, it is seen that the control system with the proposed sliding surface displays better transient per...

The problem of development microequipment is discussed. This paper contains description of the main problems connected with micro mechanical equipment developing, requirements to the micro machine tools properties, design and control systems of the prototypes of first generation machine tools, and applications of micro equipment. The mayor idea of this paper is to show the experience of the Lab...

The dimpling in the CuO2 planes of overdoped Y1−yCayBa2Cu3 O6.96−6.98, (y = 0.02−0.2) has been measured by x-ray absorption-fine-structure spectroscopy (Y-K EXAFS). A step-like decrease around 12% Ca indicates a percolation threshold for distorted sites of 5 cells, and thus phase segregation. We conclude the charge carriers added by substitution of Y by Ca to be trapped at the Ca sites and thei...

in this paper, a robust pid control scheme is proposed for micro-electro-mechanical-systems(mems) optical switches. the proposed approach is designed in a way which solves twochallenging and important problems. the first one is successful reference tracking and the second ismitigating the system nonlinearities. the overall system composed of nonlinear mems dynamicsand the pid controller is prov...
