A Knowledge-Based Approach for Integration of System Design Methodology and Documentation in Advanced Multi-Disciplinary NPD Projects
(Doctoral thesis at NTNU;2014:373, Doctoral thesis, 2014)New product development (NPD) performance depends both on developing new knowledge as well as on leveraging existent knowledge inside an organization. In project-based NPD execution knowledge is often created without a ... -
A Laboratory Approach to Investigating Wellbore Instability in Shale during Drilling
(Doctoral thesis at NTNU;2015:233, Doctoral thesis, 2015)Abstract: Over the past few years, laboratory efforts have been increasingly directed towards developing methods to understand more of the wellbore dynamics during drilling, particularly in weak shale. Hollow cylinder ... -
A Lagrangian Slug Capturing Scheme for Gas-Liquid Flows in Pipes
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:145, Doctoral thesis, 2007)In this thesis a new Lagrangian numerical scheme for the simulation of gas-liquid flows in pipelines is presented. Based on an approximate two-fluid model, this new scheme, called LASSI (Lagrangian Approximate Scheme for ... -
A Methodology for Production Development – The Body of Knowledge Approach
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:07, Doctoral thesis, 2006)The development of production line and facilities is without doubt a crucial task for the discrete goods producing industry in order to gain the competitive edge and the attention of the customer. This trend started already ... -
A modelling framework to support environmental design in regulated rivers
(Doctoral theses at NTNU;2019:141, Doctoral thesis, 2019)Despite the fact that environmental design and mitigation measures in regulated rivers have been widely applied in the last decades, yet it is still a challenge to find a method that supports a sustainable balance between ... -
A multi-method approach to explore risk factors in truck-bicycle encounters
(Doctoral theses at NTNU;2018:40, Doctoral thesis, 2018)Currently, the numbers of cyclists are increasing in many cities worldwide. People are encouraged and motivated to cycle, as it improves their health, reduces the negative effect of car traffic and creates more liveable ... -
A multidisciplinary study of shoreline landslides:From geological development to geohazard assessment in the bay of Trondheim, Mid-Norway
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:143, Doctoral thesis, 2009)The periodic occurrence of landslides in near-shore environments is common worldwide and poses a constant threat to coastal communities. Multidisciplinary studies on a regional scale have shown to be fruitful in understanding ... -
A Multiphase Pump Experimental Analysis
(Doctoral thesis at NTNU;2016:215, Doctoral thesis, 2016)This research project focuses on the characterization of the behaviour of a mixed-flow pump under off-design conditions and two-phase operation, in terms of performance degradation and instabilities. The recent multiphase ... -
