Different Types

The present article discusses the theoretical basis of generating stepping motion in microsystems. The fundamental principle is to generate asymmetry in friction force in forward and backward motions of a rigid slider by modulating the normal and tangential force. Three architecturally different mechanisms, namely directly driven embedded oscillator, slider on vibrating surface, and slider with embedded oscillator on vibrating surface models, are considered. Simple mathematical models and analytical methods for studying the dynamic characteristics of the systems are developed. Different types of systems are analysed using a unified approach. Dynamic simulation of MATLAB SIMULINK models confirms analytical results.

3 Dimensional

EM specimens often contain 3-dimensional information that is lost during micrography on a single photographic film. Two images of one specimen at appropriate orientations give a stereo view, but complex structures composed of multiple objects of graded density that superimpose in each projection are often difficult to decipher in stereo. Several analytical methods for 3-D reconstruction from multiple images of a serially tilted specimen are available, but they are all time-consuming and computationally intense.
