Status of engineering change management in the engineer-to-order production environment: insights from a multiple case study
(Peer reviewed; Journal article, 2020)Engineering Changes (ECs) are a fact of life for companies in the Engineer-To-Order (ETO) production environment. Various Engineering Change Management (ECM) strategies, practices and tools exist, but no explicit distinction ... -
Sample Strategies, Data Processing and Algorithms for Coordinate Measurements
(Doctoral theses at NTNU;2020:259, Doctoral thesis, 2020)The PhD thesis proposes new approaches and algorithms related to the field of Geometrical Dimensioning and Tolerancing (GD&T) inspection based on ISO standards on Geometrical Product Specifications (GPS). The main purpose ... -
Stress Corrosion Cracking in an Extruded Cu-Free Al-Zn-Mg Alloy
(Peer reviewed; Journal article, 2020)Stress corrosion cracking (SCC) in Cu-free Al-Zn-Mg (7xxx) aluminium alloys limits its use in many applications. In this work, we study in detail the microstructure of a peak and slightly overaged condition in an AA7003 ... -
EKF and UKF for estimating the liquid level inside gas-liquid cylindrical cyclone
(Chapter, 2019)The oil and gas industry is focussing more on subsea separation and processing and the need for compact equipment such as gas-liquid cylindrical cyclones (GLCC) is increasing. As compactness of the equipment increases, ... -
Introduction to Material Feeding 4.0: Strategic, Tactical, and Operational Impact
(Chapter, 2020)Mass customization, the process of producing a low-volume high-variety of products, is changing production environments. In Material Feeding (MF) this means a huge increment in the number of parts, and information, that ... -
Factors Affecting Shipyard Operations and Logistics: A Framework and Comparison of Shipbuilding Approaches
(Chapter, 2020)Shipyards around the world have several differences that affect the logistics processes at each yard. The purpose of this paper is to develop a framework for mapping the key factors affecting shipyard logistics. We test ... -
Tools for Evaluating Human Factor Aspects in Production and Logistics System
(Chapter, 2020)Even though the advancement of technology has a great influence on the production and logistics system (PLS), companies are more dependent on manual human work because of their cognitive ability and flexibility. Inversely, ... -
Kinematics and Dynamics of Flexible Robotic Manipulators Using Dual Screws
(Peer reviewed; Journal article, 2020)In this article, we present a new procedure for the derivation of the linearized kinematics and dynamics of a flexible industrial robotic manipulator. We introduce the Lie groups of dual rotation and dual homogeneous ... -
Preservation of Distemper Painting: Indoor Monitoring Tools for Risk Assessment and Decision Making in Kvernes Stave Church
(Peer reviewed; Journal article, 2020)The National Aeronautics and Space Administration’s (NASA) Precipitation Measurement Missions (PMMs) include two earth satellite missions, namely, the Tropical Rainfall Measuring Mission (TRMM, 1997–2015) and the Global ... -

Ductile tearing of cryogenic valve components
(Peer reviewed; Journal article, 2020)The paper reports the result of an experimental investigation on the torsional failure mechanics of the rotating components of a cryogenic valve. The rotating assembly is composed of an AISI 316L shaft connected by two ... -
Human reliability analysis: Exploring the intellectual structure of a research field
(Peer reviewed; Journal article, 2020)Humans play a crucial role in modern socio-technical systems. Rooted in reliability engineering, the discipline of Human Reliability Analysis (HRA) has been broadly applied in a variety of domains in order to understand, ... -
Qualification of the hybrid metal extrusion & bonding (HYB) process for welding of aluminium offshore structures
(Journal article, 2020)In the present investigation the aptness of the HYB process for butt welding of 4mm AA6082-T6 profiles is evaluated and benchmarked against one gas metal arc (GMA) weld and one friction stir (FS) weld, representing best ... -
High-performance stationary solar tracking through multi-objective optimization of beam-steering lens arrays
(Peer reviewed; Journal article, 2020)Beam-steering lens arrays enable solar tracking using millimeter-scale relative translation between a set of lens arrays. This may represent a promising alternative to the mechanical bulk of conventional solar trackers, ... -
An overview and evaluation of alternative forming processes for complex aluminium products
