Orbit Decomposition Method for Rotordynamic Coefficients Identification of Annular Seals
Applied Sciences, 2021 The elliptical orbit whirl model is widely used to identify the frequency-dependent rotordynamic coefficients of annular seals. The existing solution technique of an elliptical orbit whirl model is the transient computational fluid dynamics (CFD) method.

Solving Coplanar Power-Limited Orbit Transfer Problem by Primer Vector Approximation Method
International Journal of Aerospace Engineering, 2012 The coplanar orbit transfer problem has been an important topic in astrodynamics since the beginning of the space era. Though many approximate solutions for power-limited orbit transfer problem have been developed, most of them rely on simplifications of

Dynamical Friction and Orbit Circularization [PDF]
Symposium - International Astronomical Union, 1987 We study the change in shape of the orbit of a satellite sinking (because of dynamical friction) towards the center of a larger galaxy. the galaxy is assumed spherically symmetric with distribution function either isotropic or predominantly radial. the satellite is a softened point mass.

Semiclassical theory of weak antilocalization and spin relaxation in ballistic quantum dots [PDF]
, 2005 We develop a semiclassical theory for spin-dependent quantum transport in ballistic quantum dots. The theory is based on the semiclassical Landauer formula, that we generalize to include spin-orbit and Zeeman interaction.

Orbit Dynamics in Isochronous Cyclotrons [PDF]
IEEE Transactions on Nuclear Science, 1981 Acceleration of heavy ions in an isochronous cyclotron can lead to a ..nu../sub r/-value near unity for many turns. In ORIC, several departures from 3-fold symmetry unfortunately exist, so that a complex resonant behavior may lead to beam loss. To study these questions, a program has been initiated with the aim of devising and using very efficient ...

The Spin Density Matrix II: Application to a system of two quantum dots
, 2007 This work is a sequel to our work "The Spin Density Matrix I: General Theory and Exact Master Equations" (eprint arXiv:0708.0644 [cond-mat]). Here we compare pure- and pseudo-spin dynamics using as an example a system of two quantum dots, a pair of ...

Stochastic Perturbations of Periodic Orbits with Sliding [PDF]
, 2014 Vector fields that are discontinuous on codimension-one surfaces are known as Filippov systems and can have attracting periodic orbits involving segments that are contained on a discontinuity surface of the vector field.
