This paper presents the operation principles, modeling methods, design, and fabrication considerations of a 3-D micromachined accelerometer. MEMS technology in this work combines small size, low cost and low power consumption to create a sensor that is suitable for wide usage in different applications such as automotive industry and inertial navigation(More)
A VH gene segment that could not be assigned to any of the six known VH gene families of the channel catfish was identified in a genomic clone containing VH gene segments. This gene segment (designated VH7.1) exhibited the structural features characteristic of vertebrate VH genes, specifically potential upstream regulatory sequences, a leader sequence split(More)
Rolling-element bearings are widely used in various mechanical and electrical systems. A reliable bearing fault diagnostic technique is critically needed in industries to recognize a bearing fault at its early stage so as to prevent system's performance degradation and malfunction. In this work, a genetic programming based feature reconstruction approach is(More)
