On the Accuracy of the One-step UKF and the Two-step UKF
The most accurate version of the unscented Kalman filter (UKF) involves the construction of two ensembles. To reduce computational cost, however, UKF is often implemented without the second ensemble. This simplification comes at a price, however, since, for linear systems, the one-step variation of the two-step UKF does not specialize to the classical ...

On the complexity and consistency of UKF-based SLAM [PDF]
This paper addresses two key limitations of the unscented Kalman filter (UKF) when applied to the simultaneous localization and mapping (SLAM) problem: the cubic, in the number of states, computational complexity, and the inconsistency of the state estimates. In particular, we introduce a new sampling strategy that minimizes the linearization error and

Laryngeal ectopic tonsil as a cause of dysphonia: A case report
Ectopic tonsils have been described in a number of anatomic locations in the head and neck; the pathophysiology remains unclear. Given the rarity of these lesions, there are no guidelines regarding treatment.We present a case report of lymphoid nodule ...

UKF Parameter Tuning for Local Variation Smoothing
The unscented Kalman filter (UKF) is a method to solve nonlinear dynamic filtering problems, which internally uses the unscented transform (UT). The behavior of the UT is controlled by design parameters, seldom changed from the values suggested in early UT/UKF publications.

Drone Tracking Using an Innovative UKF [PDF]
This paper addresses the drone tracking problem, using a model based on the Frenet-Serret frame. A kinematic model in 2D, representing intrinsic coordinates of the drone is used. The tracking problem is tackled using two recent filtering methods. On the one hand, the Invariant Extended Kalman Filter (IEKF), introduced in [1] is tested, and on the other
