• Optimal recovery of a radiating source with multiple frequencies along one line 

  Brander, Tommi; Ilmavirta, Joonas; Piiroinen, Petteri; Tyni, Teemu (American Institute of Mathematical Sciences (AIMS), 2020)

  We study an inverse problem where an unknown radiating source is observed with collimated detectors along a single line and the medium has a known attenuation. The research is motivated by applications in SPECT and beam ...

• Determining a Random Schrödinger Operator : Both Potential and Source are Random 

  Li, Jingzhi; Liu, Hongyu; Ma, Shiqi (Springer, 2021)

  We study an inverse scattering problem associated with a Schrödinger system where both the potential and source terms are random and unknown. The well-posedness of the forward scattering problem is first established in a ...

• Recovering a Variable Exponent 

  Brander, Tommi; Siltakoski, Jarkko (Fakultät für Mathematik, Universität Bielefeld, 2021)

  We consider an inverse problem of recovering the non-linearity in the one dimensional variable exponent p(x)-Laplace equation from the Dirichlet-to-Neumann map. The variable exponent can be recovered up to the natural ...

• Kinemaattinen inversio-ongelma pallosymmetrisellä monistolla 

  Mönkkönen, Keijo (2017)

  Tutkielman pääaiheena on maanjäristysaaltoihin ja Maan sisärakenteen tutkimiseen liittyvä käänteinen kinemaattinen ongelma. Maapalloa mallinnetaan kolmiulotteisella kompaktilla reunallisella monistolla \(\bar{B}^3(0, R)\), ...

• Applications of Microlocal Analysis in Inverse Problems 

  Salo, Mikko (MDPI AG, 2020)

  This note reviews certain classical applications of microlocal analysis in inverse problems. The text is based on lecture notes for a postgraduate level minicourse on applications of microlocal analysis in inverse problems, ...
