Anything technical could appear in this section -- other than technical climbing.
New item! This note describes a different approach to
synthesizing "pink noise" using
multiple non-white random generator stages. It is based on
previous experiments posted on
this site, correcting some known deficiencies. Though not
the most efficient method known, it is is very close, and
it produces better spectral properties. Suitable for test signal
generation and digital music applications.
Moderately new item. How to bound the measurement data
set of a nominally circular element so that the bounds
are as tight as possible. This is known
as "the zone circularity problem"
and is one way to test whether a part is manufactured
within tolerance.
Everything you wanted to know about
left recursion in context free language grammars:
Which is better, PID control or state space control? Perhaps this begs the real question.
Here is an alternative to the usual fully linearized models used to represent a hydraulic actuator in nonlinear control systems. Maybe better? Who knows, never tried...
