A Fast Method for Designing Time-Optimal Gradient Waveforms for Arbitrary k-Space Trajectories
A fast and simple algorithm for designing time-optimal waveforms is presented. The algorithm accepts a given arbitrary multi-dimensional k-space trajectory as the input and outputs...

A state space model for online polyphonic audio-score alignment
We present a novel online audio-score alignment approach for multiinstrument polyphonic music. This approach uses a 2-dimensional state vector to model the underlying score positi...
