    Automatyczna ocena zaburzeń emisji głosu będących wynikiem procesów neurodegeneracyjnych w oparciu o analizę wyizolowanych głosek
    (Wydawnictwa AGH, 2006) Orzechowski, Tomasz Stanisław; Chmurzyńska, Katarzyna; Radkowski, Piotr
    This paper presents results of preliminary research of voice pathological changes caused by dysarthria. Computer analysis of voice may lead to identification of parameters correlated with neurological diseases. The selection of linguistic material was characterized according to the place and manner of articulation in the phonetic system of Polish. Results of clinical examination allowed to determine simple markers of neurodegenerative diseases, which will serve as a basis for construction of objective examination model.

    Stochastic analysis in the acoustics of damped sounds
    (2014) Banek, Tadeusz
    A stochastic model of sound propagation in damping medium is proposed. It consists of: (1) Ito's stochastic differential equation describing the sound propagation, (2) a potential which models the damping effects. However, due to presence of path integrals this model is elaborate and time consuming, hence inappropriate for numerical simulations and/or model calibrations. To make it simpler we used the classical results of stochastic analysis, Feynman-Kac formula and Girsanov tansformation obtaining easy-to-use computational procedure for practical purposes.
