Rheology of Particle Suspensions: Fresh Concrete, Mortar and Cement Paste with Various Types of Lignosulfonates
(Dr. ingeniøravhandling, 0809-103X; 2003:18, Doctoral thesis, 2003)The major issue concerns how the different lignosulfonate types changes the rheological properties of the cement based material (concrete, mortar and cement paste) as a function of temperature and time. In such terms, it ... -
Risk and Reliability Based Calibration of Structural Design Codes: Principles and Applications
(Doctoral theses at NTNU;2017:342, Doctoral thesis, 2017)Structures and infrastructures are essential for most societal activities and are required to be safe, as well as economically and environmentally sustainable. At the same time, societal resources of all kinds are limited. ... -
Risk-based Design of an Offshore Wind Turbine using VoI Analysis
(Chapter, 2019)Monopiles are the most common solution for supporting wind turbines in offshore conditions. At the design phase of a monopile, a frequency check is to be performed to avoid the resonance hazard with the 1P and 3P excitation, ... -
Risk-based Fatigue Design Considering Inspections and Maintenance
(Peer reviewed; Journal article, 2020)The different phases of a structure’s life-cycle are managed by different teams with little interaction. Correspondingly, the optimization of the individual phases is isolated and does not necessarily result in optimal ... -
Robust Cardiovascular Models for Prediction of Hypertension Using Minimal Data Sets
(Doctoral theses at NTNU;2023:225, Doctoral thesis, 2023)Cardiovascular disease is the leading cause of death worldwide. Such diseases are multifaceted, but can manifest as acute events such as cardiac infactions, strokes and aortic dissections which can lead directly to death ... -
A robust line-tracking photogrammetry method for uplift measurements of railway catenary systems in noisy backgrounds
(Peer reviewed; Journal article, 2020)For electrical railways, contact wires are used to ensure stable and continuous power supply to trains operating on the infrastructure. One crucial design parameter used to control the catenary design is the vertical ... -
