The convergence rate of the Least Mean Squares (LMS) algorithm is poor whenever the adaptive lter input auto-correlation matrix is ill-conditioned. In this paper we propose a new LMS algorithm to alleviate this problem. It uses a data dependent signal transformation. The algorithm tracks the subspaces corresponding to clusters of eigenvalues of the auto-correlation matrix of the input to the ad...

OBJECTIVE To evaluate the maximum residual signal auto-correlation also known as pitch amplitude (PA) values in patients with Parkinson's disease (PD) patients. METHOD The signals of 21 Parkinson's patients were compared with 15 healthy individuals, divided according age and gender. RESULTS Statistical difference was seen between groups for PA, 0.39 for controls and 0.25 for PD. Normal valu...

1 AbstractThe estimation of time-varying instantaneous frequency for monocomponent signals with incomplete set of samples is considered. A suitable time-frequency distribution reduces the nonstationary signal into a local sinusoid over the lag variable prior to Fourier transform. Accordingly, the observed spectral content becomes sparse and suitable for compressive sensing reconstruction in the...

The lattice contribution to thermal conductivity of single-walled carbon nanotubes with three different screw symmetry (chirality) is studied using the Green–Kubo relation from linear response theory and molecular dynamics based thermal current auto-correlation functions. The interactions between carbon atoms are analyzed using the Adaptive Intermolecular Reactive Empirical Bond Order (AIREBO) ...

We present a Galilean invariant, momentum conserving first order Brownian dynamics scheme for coarse-grained simulations of highly frictional soft matter systems. Friction forces are taken to be with respect to moving background material. The motion of the background material is described by locally averaged velocities in the neighborhood of the dissolved coarse coordinates. The velocity variab...

Modelling traffic generated by Internet based multiplayer computer games has attracted a great deal of attention in the past few years. In part this has been driven by a desire to properly simulate the network impact of highly interactive online game genres such as the first person shooter (FPS). Past work has dealt with packet size and packet interarrival times without consideration of packet ...
