The Observational Study on Wind Speed, Temperature and Humidity Profiles in the Surface Layer in Taklimakan Desert Hinterland;

Obtained are a few typical patterns of wind change versus height in the boundary layerthrough analysis of 1987 profiles and meridionally and zonally mean vertical circulation cells fordifferent levels from surface up to 3000 m.

Calculating profile is a complex work because there are many complex parts mated parts in drive process.

A new method of CAD animation for drawing cam profile of engine;

Optimal design of cam profile by means of non-uniform (B-spline) curve;

Through application of polar method to the equivalent four bar linkage of the cam mechanism, the principle of a new graphic method for determing the radius of curvature of planar cam profile is studied, the geometric and kinematic relationships are given.
