What are marginal rays and how are they different from paraxial rays with respect to the principal axis?

Sep 27, 2012 ... SUMMARY The principal axis angle ξ0, or Kagan angle, is a measure of the difference between the orientations of two seismic moment tensors. Apr 20, 2023 ... There are a couple aspects of what is implemented in ITK that makes it more complicated than basic index based moment calculations. First the ... Jan 29, 2015 ... This paper presents an alternative decomposition of spatial stiffness matrices based on the concept of compliant axes. Principal axes for both the hour-averaged and low-passed currents were ... ellipticity = 1 - (minor axis / major axis) where. UV = Sum(u*v) - n U V. UU ...

Effects of under- and overextraction on principal axis factor analysis with varimax rotation. · Citation. Wood, J. M., Tataryn, D. J., & Gorsuch, R. L. (1996). Asteroid (5247) Krylov is spinning in a short axis mode characterized by rotation and precession periods of 368.7 and 67.27 h, respectively. The principal axes are those for which the product of inertia is zero. For any arbitrary shape there exists a set of axes which result in zero product of ...
