A brute-force spectral approach for wave estimation using measured vessel motions
(Journal article; Peer reviewed, 2018)The article introduces a spectral procedure for sea state estimation based on measurements of motion responses of a ship in a short-crested seaway. The procedure relies fundamentally on the wave buoy analogy, but the wave ... -
A case study of life cycle impacts of small-scale fishing techniques in Thailand
(Journal article; Peer reviewed, 2017)Fish provides an important source of protein, especially in developing countries, and the amounts of fish consumed are increasing worldwide (mostly from aquaculture). More than half of all marine fish are caught by small-scale ... -
A Closed Loop Inverse Kinematics Solver Intended for Offline Calculation Optimized with GA
(Journal article; Peer reviewed, 2018)This paper presents a simple approach to building a robotic control system. Instead of a conventional control system which solves the inverse kinematics in real-time as the robot moves, an alternative approach where the ... -
A combined isotropic, kinematic and distortional hardening model for aluminum and steels under complex strain-path changes
(Journal article; Peer reviewed, 2018)In this work, a new model is proposed for predicting stress transients caused by strain path changes. The model is formulated in stress space, where a second order tensor, i.e., the microstructure stress deviator, is used ... -
A Combined Level Set/Ghost Cell Immersed Boundary Representation for Simulations of Floating Bodies
