  • Yield stress of aerated cement paste 
    Feneuil, Blandine Fleur Prudence; Roussel, Nicolas; Pitois, Olivier (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)
    Yield stress of aerated cement paste is studied. Samples are prepared by mixing aqueous foam with cement paste, which allows controlling bubble size, gas volume fraction and yield stress of the cement paste. Two distinct ...
  • Zero or One, Up or Down: Statistical Inference for Binary Data with Applications in Sensitivity Analysis of Energetic Materials 
    Christensen, Dennis (Doctoral thesis / Doktoravhandling, 2024)
    This thesis is about statistical analysis of binary data, and presents both new methodological advances and practical applications. On the methodological side, the thesis presents a new importance sampling algorithm for ...
  • Zero sum sign-central matrices and applications 
    Barragan, Luis A.; Dahl, Geir; Dominguez, Alberto; Otin, Arantxa (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2016)
    A matrix with a nonzero nonnegative vector in its null space is called central . We study classes of central matrices having zero column sums. The study is motivated by an engineering application concerning induction ...
  • A Zero-Coupon Bond based Spread Option : An Application of the Heath-Jarrow-Morton ModelRestricted Access 
    Skåre, Kjersti Rekdal (Master thesis / Masteroppgave, 2013)
    In this thesis we derive the price of a spread option based on two zero-coupon bonds. The two bonds will represent di erent nancial markets, and the HJM framework is used as the model for the underlying forward rates. We ...
  • Zero-one completely positive matrices and the A(R, S) classes 
    Dahl, Geir; Haufmann, Torkel Andreas (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    A matrix of the form A = BBT where B is nonnegative is called completely positive (CP). Berman and Xu (2005) investigated a subclass of CP-matrices, called f0, 1g-completely positive matrices. We introduce a related concept ...
  • Δ-EXTENSION AND HANF-NUMBERS 
    Väänänen, Jouko (Research report / Forskningsrapport, 1978)
