Pick-place of single nanowires inside scanning electron microscopes (SEM) is useful for prototyping functional devices and characterizing nanowires' properties. Nanowire pick-place has been typically performed via teleoperation, which is time-consuming and highly skill-dependent. This paper presents a robotic system capable of automated pickplace of single nanowires. Through SEM visual detection and...
This paper presents a MEMS device for simultaneous mechanical and electrical characterization of individual nanowires. The device consists of an electrostatic actuator and two capacitive sensors, enabling it to acquire all mechanical measurement data (force and displacement) electronically without relying on electron microscopy imaging. Electrical insulation within the suspended structures of the...
Nanomanipulation inside a scanning electron microscope (SEM) has been employed to maneuver and characterize nanomaterials. Despite recent efforts toward automated nanomanipulation, it is still largely conducted manually. In this paper, we demonstrate automated nanomanipulation inside an SEM for a well-structured nanomanipulation task via visual servo control and a vision-based contact detection method...
To address the problem of less rare data and low detection accuracy, The paper proposes a heterogeneous classifier integrated by the random forests, support vector machines, clustering and Bayesian classifier to increase the detecting accuracy of rare class, and to detect rare class with the greatest weighted voting. Experimental results show that utilizing integration of heterogeneous classifiers...
A video sequence of a head moving across a large pose angle contains much richer information than a single-view image, and hence has greater potential for identification purposes. This paper explores and evaluates the use of a multi-frame fusion method to improve face recognition in the presence of strong shadow. The dataset includes videos of 257 subjects who rotated their heads by 0° to 90°. Experiments...
An improved waveguide to microstrip probe transition based on LTCC (Low Temperature Co-fired Ceramic) technology is proposed at Ka-band. To widen the bandwidth of the transition, a matching structure beneath the probe is buried, which is formed by installing conducting ground stripes on different substrate layers connected by the staggered via side walls. The improved transition achieves over the...
The airfield lighting system is very important for airplanes to land and take off safely. It is especially important for night flights. However the environments for the airfield lighting are usually rough and wide, posing great difficulties to inspection and maintaining. For these reasons a airfield lighting monitoring system is urgently required. It could detect the failure position quickly and accurately...
Because sketches represent the original faces in a much concise yet recognizable form, they play an important role in criminal investigations, human perceptions and biometrics. In this work, we compared the performances of humans and a PCA-based algorithm in recognizing face sketches. A total of 250 sketches of 50 subjects were involved. All sketches were drawn manually by five artists (each artist...
