The acoustical performance of a Coulomb Fiction damper, consisting of a case-hardened roll-threaded collar resting against a reverse taper segment of drill rod is discussed. Because of the axial impact, many transverse bending modes of vibration are excited in a long prismatic drill rod, along with longitudinal and torsional resonances. The collar is caused to simultaneously move axially due to its inertia and rotate on the rolled thread, illustrating its self-tightening nature. The collar consequently presses on the case-hardened tapered surface of the drill rod, inducing interfacial frictional rubbing which is conclusively shown to be present, resulting in 30 dB of attenuation of the modes of vibration. These observations are experimentally shown and theoretically verified.

Through constructing an average opacity buffer with the same size of opacity buffer, the visibility of data cell could be estimated by the value of gravity center of this data cell in average opacity buffer. That could make the data cell which completely located in the average opacity buffer cut during the process of volume rendering in object space sequenced irregular data field and could dramatically reduce the data volume and accelerate the rendering process.

In this paper, spherical panoramic image construction and real-time navigation based on spherical panoramic image are studied. Blank image hole is eliminated through the way of "inverse interpolation";image matching through a hierarchical search strategy and spherical panoramic image is constructed through image fusion; real-time virtual navigation based on spherical panoramic image is implemented through the designed look-up table. Experiment proves responsibility of algorithm proposed in this paper and good result is gained.

This paper proposed an algorithm of collision detection based on a hybrid model which was different from other collision detection model. In this model, different box was used according to different occasion. And the algorithm of intersection calculation between bounding boxes was analyzed and finally the optimization of collision detection based on the hybrid model was gained.
