Automatic Parametrisation and Block pseudo Likelihood Estimation for binary Markov random Fields
Toftaker, Håkon (Master thesis, 2008)Discrete Markov random fields play an important role in spatial statistics, and are applied in many different areas. Models which consider only pairwise interaction between sites such as the Ising model often perform well ... -
High-Voltage Circuit Breaker Condition-Dependent Failure Rate with Covariates
Grant, Jordon Ashley; Toftaker, Håkon; Perkin, Samuel; Sperstad, Iver Bakken; Vadlamudi, Vijay Venu (Peer reviewed; Journal article, 2024)High-voltage circuit breakers (HVCBs) are essential protection devices which should also be included in power system reliability analysis. When using Monte-Carlo simulation methods the reliability of individual components ... -
Joint optimization of preventive and condition-based maintenance for offshore wind farms
Toftaker, Håkon; Bødal, Espen Flo; Sperstad, Iver Bakken (Peer reviewed; Journal article, 2022)High costs of maintenance and lost production during downtime are a challenge to the offshore wind industry, and there is a great potential to improve cost efficiency by improved maintenance and control strategies utilizing ... -
