Global behaviour corresponding to the absolute instability of the rotating-disc boundary layer [PDF]
, 2003 A study is carried out of the linear global behaviour corresponding to the absolute instability of the rotating-disc boundary layer. It is based on direct numerical simulations of the complete linearized Navier–Stokes equations obtained with the novel ...

On the Self-Consistent Response of Stellar Systems to Gravitational Shocks [PDF]
, 1999 We study the reaction of a globular star cluster to a time-varying tidal perturbation (gravitational shock) using self-consistent N-body simulations and address two questions.

Persistent junk solutions in time-domain modeling of extreme mass ratio binaries
, 2010 In the context of metric perturbation theory for non-spinning black holes, extreme mass ratio binary (EMRB) systems are described by distributionally forced master wave equations.

Multi-Objective Robust H-infinity Control of Spacecraft Rendezvous [PDF]
, 2009 Based on the relative motion dynamic model illustrated by C-W equations, the problem of robust Hinfin control for a class of spacecraft rendezvous systems is investigated, which contains parametric uncertainties, external disturbances and input ...

Small-amplitude perturbations in the three-dimensional cylindrical Richtmyer–Meshkov instability [PDF]
, 2009 We first study the linear stability of an interface between two fluids following the passage of an imploding or exploding shock wave. Assuming incompressible flow between the refracted waves following shock impact, we derive an expression for the ...

Widespread nanoflare variability detected with Hinode/XRT in a solar active region [PDF]
, 2011 It is generally agreed that small impulsive energy bursts called nanoflares are responsible for at least some of the Sun's hot corona, but whether they are the explanation for most of the multi-million degree plasma has been a matter of ongoing debate ...

Modeling and control of complex dynamic systems: Applied mathematical aspects [PDF]
, 2012 The concept of complex dynamic systems arises in many varieties, including the areas of energy generation, storage and distribution, ecosystems, gene regulation and health delivery, safety and security systems, telecommunications, transportation networks,

Optimal on-off cooperative manoeuvers for long-term satellite cluster flight [PDF]
, 2014 When a group of satellites is equipped with a particulary simple propul- sion system, e.g. cold-gas thrusters, constraints on the thrust level and total propellant mass renders cluster-keeping extremely challenging.

Persistent Evidence of a Jovian Mass Solar Companion in the Oort Cloud
, 2010 We present an updated dynamical and statistical analysis of outer Oort cloud cometary evidence suggesting the sun has a wide-binary Jovian mass companion.
