Computer Simulation of Residual Stress and Distortion of Thick Plates in Multielectrode Submerged Arc Welding: Their Mitigation Techniques
(Dr. ingeniøravhandling, 0809-103X; 2001:75, Doctoral thesis, 2001)Welding is the main joining method used in shipbuilding. A multi-electrode submerged arc welding is usually applied to long joints of massive components since the early 1950s. The problem of welding stresses and deformations ... -
Creep in soft Soils
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:77, Doctoral thesis, 2004)As more and more constructions are concentrated in densely populated urban areas, there is an increasing need to construct buildings and geotechnical structures on soft clay materials, which usually produce significant ... -
Current Forces on Net Structure
(Doctoral Theses at NTNU, 1503-8181; 2005:64, Doctoral thesis, 2005)The trend in recent years has been that the amount of wild catch is stagnating. In this perspective the selectivity of fishing gear has become an important issue. The aim of the present work has been to develop a ... -

Decompressive Pathology in Cetaceans Based on an Experimental Pathological Model
(Peer reviewed; Journal article, 2021)Decompression sickness (DCS) is a widely known clinical syndrome in human medicine, mainly in divers, related to the formation of intravascular and extravascular gas bubbles. Gas embolism and decompression-like sickness ... -
Deformations in Concrete Cantilever Bridges: Observations and Theoretical Modelling
(Dr. ingeniøravhandling, 0809-103X; 2002:23, Doctoral thesis, 2002)The thesis deals with the deformation problem of segmental, cast-in-place concrete cantilever bridges. This type of bridge has shown some propensity to develop larger deflections than those were predicted in the design ... -
Deposit Formation on Cylinder Liner Surface in medium-speed Engines
(Dr. ingeniøravhandling, 0809-103X; 2003:87, Doctoral thesis, 2003)The presence of deposits in the honing grooves in diesel engine cylinder liners can cause a severe increase in the consumption of lubricating oil. These deposits may appear amber in which case they may be referred to as ... -
Derivative free optimal thrust allocation in ship dynamic positioning based on direct search algorithms
(Peer reviewed; Journal article, 2020)ABSTRACT: In dynamic positioning systems, nonlinear cost functions, as well as nonlinear equality and inequality constraints within optimal thrust allocation procedures cannot be handled directly by means of the solvers ... -
Design, Operation and Control Modelling of SOFC/GT Hybrid Systems
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:28, Doctoral thesis, 2006)This thesis focuses on modelling-based design, operation and control of solid oxide fuel cell (SOFC) and gas turbine (GT) hybrid systems. Fuel cells are a promising approach to high-efficiency power generation, as they ... -
Dynamic characteristics and leakage performance of liquid annular seals in centrifugal pumps
(Dr. ingeniøravhandling, 0809-103X; 2000:1, Doctoral thesis, 2000)In centrifugal pumps the leakage and dynamic characteristics of annular seals are important factors for pump performance. Both seal leakage and dynamics are greatly affected by the relationship between fluid flow and wall ... -
Dynamics of the Seasonal Snowcover in the Arctic
(Dr.ingeniøravhandling, 0809-103X; 2002:29, Doctoral thesis, 2002)Arctic snow cover is important to life on Earth from the microscale soil microarthropod population, to reindeer at the local scale and even the global scale through its impact on the global climate. There ... -
