Modelling the Utility of Group Testing for Public Health Surveillance
Günther Koliander, Georg Pichler
In epidemic or pandemic situations, resources for testing the infection status of individuals may be scarce. Although group testing can help to significantly increase testing capab…
Continuous frames in tensor product Hilbert spaces, localization operators and density operators
Peter Balazs, Nenad Teofanov
Continuous frames and tensor products are important topics in theoretical physics. This paper combines those concepts. We derive fundamental properties of continuous frames for ten…
A comparative study of eight human auditory models of monaural processing
Alejandro Osses Vecchi, Léo Varnet, Laurel H. Carney +4
A number of auditory models have been developed using diverging approaches, either physiological or perceptual, but they share comparable stages of signal processing, as they are i…
Time-Frequency Phase Retrieval for Audio -- The Effect of Transform Parameters
Andrés Marafioti, Nicki Holighaus, Piotr Majdak
In audio processing applications, phase retrieval (PR) is often performed from the magnitude of short-time Fourier transform (STFT) coefficients. Although PR performance has been o…
Spectral deviation of concentration operators for the short-time Fourier transform
Felipe Marceca, José Luis Romero
Time-frequency concentration operators restrict the integral analysis-synthesis formula for the short-time Fourier transform to a given compact domain. We estimate how much the cor…
On compactly supported dual windows of Gabor frames
Diana T. Stoeva
The main purpose of the paper is to give a characterization of all compactly supported dual windows of a Gabor frame. As an application, we consider an iterative procedure for appr…
