    • Vitenskap og moralfilosofi. Et forsvar av Joshua Greenes kritikk av deontologisk etikk. 

      Lorentsen, Torjus (Master thesis; Mastergradsoppgave, 2018-05-15)
      Joshua Greene argumenterer for at deontologisk etikk er uegnet som normativ teori fordi den har sitt opphav i nevrologiske- og psykologiske prosesser som er sensitive for faktorer som ikke er moralsk relevante. Jeg argumenterer for at normativ etikk, representert ved debatten mellom deontologi og konsekvensialisme, er en disiplin preget av stillstand, og at Greenes prosjekt har potensial til å bøte ...

    • Skewed Lorentzian pulses and exponential frequency power spectra 

      Garcia, Odd Erik; Theodorsen, Audun (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-18)
      Frequency power spectra due to a super-position of uncorrelated Lorentzian pulses with a random distribution of amplitudes are considered. For pulses with a constant duration, there is an exponential frequency spectrum which is independent of the degree of pulse overlap and the pulse amplitude distribution. The spectrum is furthermore shown to be unaffected by skewness of the Lorentzian pulses and ...
