A modular approach to the modelling and analysis of risk scenarios with mutual depenencies
Brændeland, Gyrd; Dahl, Heidi Elisabeth Iuell; Stølen, Ketil (Research report, 2008)This report describes a modular approach to the modelling and analysis of risk scenarios with mutual dependencies. The presented approach may be used to deduce the risk-level of an overall system from previous risk analyses ... -
Deconfliction and Surface Generation from Bathymetry Data Using LR B-splines
Skytt, Vibeke; Harpham, Quillon; Dokken, Tor; Dahl, Heidi Elisabeth Iuell (Chapter, 2017)A set of bathymetry point clouds acquired by different measurement techniques at different times, having different accuracy and varying patterns of points, are approximated by an LR B-spline surface. The aim is to represent ... -
Structured Semantics for the CORAS Security Risk Modelling Language
Dahl, Heidi Elisabeth Iuell; Stølen, Ketil; Hogganvik, Ida (Research report, 2007)The CORAS security risk modelling language is a customised graphical language for com- munication, documentation and analysis of security threat and risk scenarios. We present a textual syntax and a structured semantics ... -
Symmetries of canal surfaces and Dupin cyclides
Alcazar, Juan Gerardo; Dahl, Heidi Elisabeth Iuell; Muntingh, Agnar Georg Peder (Journal article; Peer reviewed, 2017)We develop a characterization for the existence of symmetries of canal surfaces defined by a rational spine curve and rational radius function. In turn, this characterization inspires an algorithm for computing the symmetries ...
