projected areaIn deriving particle size, volume and concentration from laser diffraction experiments, it is normally assumed that the particles are spheres. For other shapes the projected area is not constant but rather has a range of values. Because the orientation of the body is usually random,...
A freeform projection display includes an optical emitter configured to output one or more wavelengths of light and an optical diffuser optically coupled to receive and disperse the one or more wavelengths of light from the optical emitter, wherein the optical diffuser has at least one radius of ...

Automotive pistons, cylinder heads, engines are some of the commonly manufactured articles using aluminum casting process. Aluminum Castings these days are majorly manufactured from secondary aluminum, i.e. aluminum obtained after recycling the used alum...
The edges of IpIp and IqIq were detected using a Canny edge detector [7] . In addition, we designed a method for obtaining IpIp and IqIq . The principle of determining the projection direction is to maximize the projection area of the common parts of P and Q. Based on this ...
the drag coefficient: CD = FD /A 1 2 ρ U∞2 VII- 17 It is noted that it is common to see one of three reference areas used depending on the application: 1. Frontal (projected) area: Used for thick, stubby, non-aerodynamic shapes, e.g., buildings, cars, etc. 2. Planform (...
A zero-stretch solution is possible only when the surface is developable. Example developable surfaces are two planar walls meeting at a corner, or a segment of a right cylinder, i.e., a planar curve extruded perpendicular to the plane. In other cases, such as two planar walls and a ceil...
And it is also considered in the cases; the body moves in a time as well as in the same distance. At least in theory, I expect this paper will show the final conclusion.Keywords -Run or walk in the rain, orthogonal projected area of ellipsoid, cylinder and rectangular...
The short diameter is changed from big to small, and the gap of matching cylinder is reduced. The uniformity of the contact face of the piston skirt is realized, enough bearing area to bear the side thrust beard by the piston is provided to guarantee the steady piston motion, and a ...
