Conditions for suboptimal filter stability in SLAM
 In Proceedings of the IEEE/RSJ International Conference on Intelligent Robots and Systems
, 2004
"... Abmad In this article, we show marginal stability in SLAM, guaranteeing convergence to a nonzero mean state error estimate bounded by a constant value. Moreover, marginal stability guarantees also convergence of the Riccati equation of the onestep ahead state error covariance to at least one psd ..."

steady slate solution. In the search far realtime implementations of SLAM, covariance inllation methods produce a suboptimal filter that erentually may lead to the computation of an unbounded state error covariance. We provide tight constraints in Le amount of decorrelation possible, to guarantee
Effect of HighFrequency Temporal Aliasing on GOCE Gravity Field Solution
"... European Space Agency's Gravity field and steady state Ocean Circulation Explorer (GOCE) space gravity gradiometer (SGG) mission is anticipated to determine the mean gravity field of the Earth with an unprecedented geoid accuracy of several cm rms with wavelength of 130 km or longer. In a suns ..."

Algorithms
"... A timedomain algorithm for computation of the noise power spectral density (PSD) is proposed in [17]. When applied to periodically varying circuits, this formulation requires efficient methods to obtain the quasiperiodic steadystate solution of a set of linear timevarying ordinary differential ..."

THE STABILIZATION OF BUDKERCHIRIKOV INSTABILITY BY THE SPREAD OF LONGITUDINAL VELOCITIES
"... The twobeams electron ion system consists of a nonrelativistic ion beam propagating coaxially with a highcurrent relativistic electron beam in a longitudinal homogeneous magnetic field [1]. The effect of spread of longitudinal velocities of an electron beam on instability BudkerChirikov (BCI) i ..."

conditions for the potentials fellow from the system's axial symmetry, the presence of conducting tube with radius R and the gauge condition div A = 0. The Vlasov equations are solved by the macroparticle method. It is assumed that the steadyslate process is periodic in time set with a frequency ω
Finite time blow up in KaniadakisQuarati model of BoseEinstein particles
, 2010
"... We study a FokkerPlanck equation with linear diffusion and superlinear drift introduced by Kaniadakis and Quarati [11, 12] to describe the evolution of a gas of BoseEinstein particles. For kinetic equation of this type it is wellknown that, in the physical space R 3, the structure of the equilib ..."

of the equilibrium BoseEinstein distribution depends upon a parameter m ∗ , the critical mass. We are able to describe the timeevolution of the solution in two different situations, which correspond to m ≪ m ∗ and m ≫ m ∗ respectively. In the former case, it is shown that the solution remains regular, while
