This paper presents a general method to Ž t the Schöner–Haken–Kelso (SHK) model of human movement phase transitions directly to time series data. A robust variant of the extended Kalman Ž lter technique is applied to the data of a single subject. The options of covariance resetting and iteration within recursion were used to obtain timedependent estimates of both the a and b parameters in the S...

In this paper a fast method for the calculation of a linear time-frequency distribution based on the gammatone lter auditory model is introduced as a preprocessing step for the automated transcription of music and auditory source separation. Examples show that this method has a promising potential for the analysis of music pieces with a limited spectral overlap of the diierent signal components...

The mobile robot localization problem is treated as a two-stage iterative estimation process. The attitude is estimated rst and is then available for position estimation. The indirect (error state) form of the Kalman lter is developed for attitude estimation when applying gyro modeling. The main bene t of this choice is that complex dynamic modeling of the mobile robot and its interaction with ...

A modiied version of the QR{decomposition (QRD) is presented. It uses approximate Givens rotations instead of exact Givens rotations, i.e., a matrix entry usually annihilated with an exact rotation by an angle is only reduced by using an approximate rotation by an angle ~. The approximation of the rotations is based on the idea of CORDIC. Evaluating a CORDIC{based approximate rotation is to det...

Biorthogonal modulated "lter banks, when compared to paraunitary ones, provide the advantage that the overall system delay can be chosen independently of the "lter length, thus allowing to design low delay "lter banks. They have recently been studied by several authors. In this paper, we connect two di!erent design methods, namely the quadratic constrained least-squares optimization and the pri...

In this paper we are concerned with nonlinear systems subject to a conditionally linear, Gaussian sub-structure. This structure is often exploited in high-dimensional state estimation problems using the marginalized (aka Rao-Blackwellized) particle lter. The main contribution in the present work is to show how an e cient lter can be derived by exploiting this structure within the auxiliary part...

In this paper we have two interesting results. One is of theoretical interest and the other practical. The theoretical result is that the optimum FIR orthonormal lter bank of a xed nite degree that maximizes the coding gain does not always contain an optimum compaction lter. In other words, in general, there does not exist a principal component lter bank (PCFB) of a given nonzero degree. This i...

By extending the system theory under the (min;+)-algebra to the time varying setting, we solve the problem of constrained tra c regulation and develop a calculus for dynamic service guarantees. For a constrained tra c regulation problem with maximum tolerable delay d and maximum bu er size q, the optimal regulator that generates the output tra c conforming to a subadditive envelope f and minimi...
