Filtering for nonlinear genetic regulatory networks with stochastic disturbances [PDF]
, 2008 In this paper, the filtering problem is investigated for nonlinear genetic regulatory networks with stochastic disturbances and time delays, where the nonlinear function describing the feedback regulation is assumed to satisfy the sector condition, the ...

Density Difference Grid Design in a Point-Mass Filter
Energies, 2020 The paper deals with the Bayesian state estimation of nonlinear stochastic dynamic systems. The stress is laid on the point-mass filter, solving the Bayesian recursive relations for the state estimate conditional density computation using the ...

Nonlinear Compressive Particle Filtering [PDF]
, 2013 Many systems for which compressive sensing is used today are dynamical. The common approach is to neglect the dynamics and see the problem as a sequence of independent problems. This approach has two disadvantages. Firstly, the temporal dependency in the

Nonlinear Analysis of the BOLD Signal
EURASIP Journal on Advances in Signal Processing, 2009 The linearized filtering approach to the hemodynamic system is limited in capturing the inherent nonlinearities of physiological systems. The nonlinear estimation method therefore should be thought of as a natural way to access the nonlinear data ...

The Neural Particle Filter [PDF]
, 2016 The robust estimation of dynamically changing features, such as the position of prey, is one of the hallmarks of perception. On an abstract, algorithmic level, nonlinear Bayesian filtering, i.e.

Ice bottom evolution derived from thermistor string-based ice mass balance buoy observations
International Journal of Digital Earth, 2023 Digital information on sea ice extent, thickness, volume, and distribution is crucial for understanding Earth's climate system. The Snow and Ice Mass Balance Apparatus (SIMBA) is used to determine snow and ice temperatures in Arctic, Antarctic, ice ...

COMPARISON OF APPROACHES TO UNKNOWN PARAMETERS IDENTIFICATION IN GYRO DRIFT MODEL [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2018 The paper proposes a model of floated gyro drift, used in a platform-based inertial navigation system, which takes into account temperature effects. We consider a problem of unknown parameters identification in a mathematical model of floated gyro drift.

Observability and nonlinear filtering
, 2008 This paper develops a connection between the asymptotic stability of nonlinear filters and a notion of observability. We consider a general class of hidden Markov models in continuous time with compact signal state space, and call such a model observable

High frequency wave packets for the Schr\"odinger equation and its numerical approximations [PDF]
, 2010 We build Gaussian wave packets for the linear Schr\"odinger equation and its finite difference space semi-discretization and illustrate the lack of uniform dispersive properties of the numerical solutions as established in Ignat, Zuazua, Numerical ...
