Research on the Oscillation in Centerless Grinding …
The machine tool, the grinding tool, and the workpiece form a machining system with complex dynamic characteristics, in which the oscillation of the individual elements is a concomitant of the cutting process. Centerless grinding technology, as we know it today, was introduced in 1917 on the basis of a Heim patent.

Precondition of while loop program | Free Math Help Forum
For example, if I take x=4 and y=2, I have not satisfied (a) or (c), but it does terminate, so (a) and (c) can't be right. I believe you can similarly eliminate the other choices. All that leaves, in my mind, besides a simply bad (or miscopied) problem, is that your definition of precondition may not be what I think it is.

Difference Between Salient Pole & Cylindrical Pole Alternator
It has lower ratings than cylindrical alternators for the same size. It has higher ratings than salient pole alternators for the same size. It is used for low and medium speeds up to 100 RPM to 1500 RPM. It is used for high-speed applications up to 3000 RPM. Salient pole alternators are used in hydro turbines.
