A Variable Step-size CLMS Algorithm and Its Analysis [PDF]
Radioengineering, 2020 In this paper, a hyperbolic tangent variable step-size convex combination of the least mean square (HTVSCLMS) algorithm is proposed and analyzed. This work avoids the compromise between the convergence speed and the steady-state error for two filters in ...

Autonomous Control of the Large-Angle Spacecraft Maneuvers in a Non-Cooperative Mission
Sensors, 2022 Aiming at the large-angle maneuver control problem of tracking spacecraft attitude in non-cooperative target rendezvous and proximity tasks, under the condition that the target spacecraft attitude information is unknown and the actuator output has ...

Composition depth profiling of polystyrene/poly(vinyl ethyl ether) blend thin films by angle resolved XPS [PDF]
, 2009 Angle resolved XPS (ARXPS) and scanning force microscopy (SFM) are used to study polystyrene/poly(vinyl ethyl ether) 50/50 wt% blend thin films spin cast from toluene solution, as a function of polystyrene molecular weight and film thickness.

A characterization of harmonic measures on laminations by hyperbolic Riemann surfaces [PDF]
, 2007 We prove that a probability measure on a compact non-singular lamination by hyperbolic Riemann surfaces is harmonic if and only if it is the projection of a measure on the unit tangent bundle such that it is invariant under both the geodesic and the ...

Cusps and the family hyperbolic metric [PDF]
, 2007 The hyperbolic metric for the punctured unit disc in the Euclidean plane is singular at the origin. A renormalization of the metric at the origin is provided by the Euclidean metric. For Riemann surfaces there is a unique germ for the isometry class of a
