Spectral Study of the Vocal Tract in Vowel Synthesis: A Comparison between 1D and 3D Acoustic Analysis
Negar M. Harandi, Daniel Aalto, Antti Hannukainen +2
A state-of-the-art 1D acoustic synthesizer has been previously developed, and coupled to speaker-specific biomechanical models of oropharynx in ArtiSynth. As expected, the formant…
Efficient inclusion of total variation type priors in quantitative photoacoustic tomography
Antti Hannukainen, Nuutti Hyvönen, Helle Majander +1
Quantitative photoacoustic tomography is an emerging imaging technique aimed at estimating the distribution of optical parameters inside tissues from photoacoustic images, which ar…
Convergence analysis of GMRES for the Helmholtz equation via pseudospectrum
Antti Hannukainen
Most finite element methods for solving time-harmonic wave-propagation problems lead to a linear system with a non-normal coefficient matrix. The non-normality is due to boundary c…
Edge-promoting reconstruction of absorption and diffusivity in optical tomography
Antti Hannukainen, Lauri Harhanen, Nuutti Hyvönen +1
In optical tomography a physical body is illuminated with near-infrared light and the resulting outward photon flux is measured at the object boundary. The goal is to reconstruct i…
