NON-SQUARE BLIND SOURCE SEPARATION UNDER COHERENT NOISE BY BEAMFORMING AND TIME-FREQUENCY MASKING
NON-SQUARE BLIND SOURCE SEPARATION COHERENT NOISE BY BEAMFORMING TIME-FREQUENCY MASKING
2015/9/29
To be applicable in realistic scenarios, blind source separation approaches should deal evenly with non-square cases and the presence of noise. We consider an additive noisemixing model with an arbitr...
In three experiments we tried to mask the motions of human gait. We represented human walkers as a set of 11 computer-generated elements on a display monitor, moving as a nested hierarchy of motions t...
High-resolution Imaging of Dust Shells Using Keck aperture Masking and the IOTA Interferometer
given current calibration software limitations
2014/12/24
We present first results of an experiment to combine data from Keck aperture masking and the Infrared-Optical Telescope Array (IOTA) to image the circumstellar environments of evolved stars with …20 m...
Sparse aperture masking at the VLT I. Faint companion detection limits for the two debris disk stars HD 92945 and HD 141569
Instrumentation: high angular resolution – Stars: planetary systems – Stars: individual
2011/9/29
Observational data on companion statistics around young stellar systems is needed to flesh out the formation pathways for extrasolar planets and brown dwarfs. Aperture masking is a new technique that ...
Masking a singularity with k-essence fields in an emergent gravity metric
emergent gravity metric
2010/11/16
It is known that dynamical solutions of the k-essence equation of motion change the metric for
the perturbations around these solutions and the perturbations propagate in an emergent spacetime with m...

Indirect Complexometric Determination of Mercury Using Potassium Iodide as Selective Masking Agent
complexometry EDTA mercury determination potassium iodide masking agent
2010/6/30
This paper describes a indirect complexometric method for the determination of mercury in the presence of co-ions, based on the selective masking ability of potassium iodide. To the mixture of mercury...
