Taguchi Optimization of Parameters for Feedstock Fabrication and FDM Manufacturing of Wear-Resistant UHMWPE-Based Composites
(Peer reviewed; Journal article, 2020)It is believed that the structure and properties of parts fabricated by additive (i.e., non-stationary) manufacturing are slightly worse compared to hot pressing. To further proceed with improving the quality of Fused ... -
Tailoring Biocomposites with Reduced Water Uptake for 3D Printing
(Master thesis, 2017)In this study, two different grades of bioPE, with a varying melt flow index (MFI) were tested for making biocomposites reinforced with wood fibre. A low MFI was found to be more adequate for the manufacturing. Filaments ... -
Takt-time control in high-mix/low-volume production
(Master thesis, 2015)Purpose The purpose of this thesis is to develop a spreadsheet tool for takt planning in a high-mix/low-volume (HMLV) environment. Ultimately, the objective is to develop tool that the production planner can use to test ... -
Tangential strain‐based criteria for mixed‐mode I/II fracture toughness of cement concrete
(Journal article; Peer reviewed, 2018)Experimental and theoretical works are performed on the mixed‐mode I/II brittle fracture of cement concrete tested by edge cracked semicircular bend specimens. Theoretical background of the traditional fracture criteria ... -
Tape winding angle influence on subsea cable sheathing fatigue performance
(Peer reviewed; Journal article, 2020)A fundamental component of subsea power cables is the thin galvanized steel tape winded around the dielectric and sheathing layer in order to prevent permanent thermal cycling induced deformation. The pressure state induced ... -
Task Programming of Redundant Industrial Robots: A Virtually Extended Null Space Formulation Verified Through Obstacle Avoidance
(Master thesis, 2012)Industrial robots are an important part of modern automation and are used in a variety of applications such as handling, welding, painting and assembling. They have normally six degrees of freedom to provide an arbitrary ... -
A Taxonomy for Engineering Change Management in Complex ETO Firms
(Chapter, 2020)Abstract: In this paper, we study a specific type of Engineer-to-Order (ETO) firms called Complex ETO characterized by one-of-a-kind products with high complexity and low volumes. Such firms are at high risk of encountering ... -
TCN-based Machine Learning Analysis of DOFS Data for Subsea Acoustic Source Localization
(Master thesis, 2023)Distribuerte Optiske Fibersensorer (DOFS) tilbyr høyoppløselige tøynings- og temperaturmålinger med lang rekkevidde og som har en minimal innvirkning på måleobjektene, og derfor i økende grad benyttes for måling av både ... -
