Dynamical analysis of iterative methods for nonlinear systems or how to deal with the dimension?

Cordero Barbero, Alicia et al. (1 oct. 2014)

This paper deals with the real dynamical analysis of iterative methods for solving nonlinear systems on vectorial quadratic polynomials. We use the extended concept of critical point and propose an easy test to determine the stability of fixed points to multivariate rational functions. Moreover, an ...

Characterization of the gaseous companion κ Andromedae b. New Keck and LBTI high-contrast observations

Bonnefoy, M. et al. (2014)

Context. We previously reported the direct detection of a low-mass companion at a projected separation of 55 ± 2 AU around the B9-type star κ Andromedae. The properties of the system (mass ratio, separation) make it a benchmark for understanding the formation and evolution of gas giant planets ...

Global Optimization using Interval Analysis: Interval Optimization for Aerospace Applications

Van Kampen, E. (24 sept. 2010)

Optimization is an important element in aerospace related research. It is encountered for example in trajectory optimization problems, such as: satellite formation flying, spacecraft re-entry optimization and airport approach and departure optimization; in control optimization, for example in ...

Dinámica y caos de operadores desplazamiento

GALÁN CÉSPEDES, VÍCTOR JOSÉ (18 déc. 2015)

[EN] A continuous and linear operator defined on a Banach space is hipercyclic if it supports a dense orbit, that is, if there exists a vector such that the set of all its iterations through the operator is dense in the space. The existence of dense orbits is closely related to the dynamic concept ...

PPP technique analysis based on time convergence, repeatability, IGS products, different software processing and GPS+Glonass constellation: a case study

Martín Furones, Ángel Esteban et al. (2011)

In recent years interest has increased for precise point positioning (PPP), which provides an alternative to precise relative processing because of its potential as a reliable absolute positioning technique. PPP technique takes advantage of satellite orbit and clock products obtained from the global ...

Understanding the equatorial ocean : theoretical and observational studies

Rabitti, A. (26 janv. 2016)

By means of a variety of approaches, the present study points out the challenges in understanding equatorial ocean dynamics (±2.5º). Standard theory, in fact, fails in accurately describing such a big portion of our ocean. This is mainly because at the equator rotation and density stratification ...

Bifurcation of periodic orbits near a frequency maximum in near-integrable driven oscillators with friction

Valkering, T.P. et al. (1993)

We investigate analytically the effect of perturbations on an integrable oscillator in one degree of freedom whose frequency shows a maximum as a function of the energy, i.e. a system with nonmonotone twist. The perturbation depends on three parameters: one parameter describes friction such that the ...

Hierarchical systems

Hamers, A.S. (21 juin 2016)

The thesis addresses the long-term dynamical evolution of hierarchical multiple systems. First, we consider the evolution of orbits of stars orbiting a supermassive black hole (SBH). We study the long-term evolution and compute tidal disruption rates of stars by the SBH. Such disruption events ...
