• Electromagnetic wave propagation in non-homogeneous waveguides 

  Poretskii, Aleksandr (University of Jyväskylä, 2015)

  We investigate an electromagnetic waveguide, having several cylindrical ends. The waveguide is assumed to be empty and to have a perfectly conductive boundary. We study the electromagnetic field, excited in the waveguide ...

• 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 ...

• Where Cyber Meets the Electromagnetic Spectrum 

  Henselmann, Gerhard; Lehto, Martti (Academic Conferences International, 2019)

  Cyber linked with Information Technology, computers and the internet are the most commonly understood potential threats that everybody is aware of nowadays. In the case of National Cyber Strategy most efforts are given to ...

• The M4 transitions of isomeric states 

  Jokiniemi, Lotta (2015)

  Tässä pro gradu -tutkielmassa tutkitaan isomeeristen tilojen magneettisten M4-gammasiirtymien redusoituja matriisielementtejä. Tutkittavat siirtymät ovat venyneitä M4-siirtymiä kaksoisbeetahajoamisten massa-alueilla A=85-115 ...

• Decay estimates for time-fractional and other non-local in time subdiffusion equations in R^d 

  Kemppainen, Jukka; Siljander, Juhana; Vergara, Vicente; Zacher, Rico (Springer, 2016)

  We prove optimal estimates for the decay in time of solutions to a rather general class of non-local in time subdiffusion equations in R d . An important special case is the timefractional diffusion equation, which has ...
