Comparison of the AS-MBR and BF-MBR processes
(Master thesis, 2010)Active sludge membrane bioreactor (AS-MBR) is a process of membrane separation of activated sludge. This is increasingly becoming an alternative for wastewater treatment plants as improved effluent quality often is required ... -
Comparison of the hydraulic capacity of different culvert inlet designs under sediment transport conditions
(Master thesis, 2015)Abstract Culverts are important hydraulic structures whose main purpose is to safely convey water through infrastructures crossing streams (e.g. roads). Several design guidelines exist for clear water conditions, but none ... -
Comparison of the Svee and Thoma Stability Criteria for Mass Oscillations in Surge Tanks
(Master thesis, 2016)This thesis discusses two different criteria for the stability of surge tanks in hydropower plants. In 1910, the first stability criterion was derived by Dieter Thoma. This criterion sets a minimum cross-sectional area for ... -
Comparison of Various Insulin Pumps with Respect to Accuracy of the Insulin Delivery
(Master thesis, 2021)Insulinpumper er ofte brukt som en del av behandlingen for pasienter med Diabetes Mellitus type 1. Eksisterende forskning viser at jo lavere insulindoser, jo lavere er nøyaktigheten av insulinleveransen. Dette kan være ... -
Competence within Maintenance
(Master thesis, 2010)Maintenance can be a contributing factor to unwanted events, as well as desired events and states. Human competence can be defined as the ability to perform a specific task, action or function successfully, and is therefore ... -

The complementary effect of lean manufacturing and digitalisation on operational performance
(Peer reviewed; Journal article, 2020)The most recent trend manufacturers have embraced to seek operational performance improvements is the use of a wide range of digital technologies typically associated with Industry 4.0. However, few studies have investigated ... -
Complete Simulation Models to Describe the Ductile-to-Brittle Transition of Steels for Arctic Applications - A Beremin-Gurson Approach
(Master thesis, 2018)The toughness of common structural steels is often affected by temperature changes where low service temperatures frequently promote brittle material characteristics. Low service temperatures often occur in the Arctic ... -
Completion of Compact Separator Laboratory
(Master thesis, 2017)As the petroleum business explore deeper waters and more remote locations in the quest for new hydrocarbon reservoirs, challenges that were not that relevant in earlier years now become more common. To face these challenges, ... -
Component-Based Modeling and Simulation of Nonlinear Drill-String Dynamics
(Chapter, 2019)In this paper, we present a dynamic model for a generic drill-string. The model is developed with the intention for component-based simulation with coupling to external subsystems. The performance of the drill-string is ... -
Composite Materials in a Novel Tidal Turbine Design
(Master thesis, 2013)This thesis aims to optimize the design of a tidal turbine, by replacing steel components with composites. Initially all major turbine components such as axle, rotor and stator were considered, but in guidance with supervisor ... -
Composite Sandwich Design for Formula SAE Monocoque
(Master thesis, 2013)This paper is an approach in how to design a composite sandwich laminate, that is to be used for an open wheeled race car with a monocoque chassis. The composite sandwich design of the monocoque must be in accordance with ... -
Composite Ship Propellers
(Doctoral theses at NTNU;2024:22, Doctoral thesis, 2024)Ship propellers can be designed using composite (fibre-reinforced plastic) materials to achieve bending-induced twist deformation leading to automatic pitch adjustment in the blades during operation. Composite tailoring ... -
A comprehensive review on surface modifications of biodegradable magnesium-based implant alloy: Polymer coatings opportunities and challenges
(Peer reviewed; Journal article, 2021)The development of biodegradable implants is certainly intriguing, and magnesium and its alloys are considered significant among the various biodegradable materials. Nevertheless, the fast degradation, the generation of a ... -
A Comprehensive Study of the Microclimate-Induced Conservation Risks in Hypogeal Sites: The Mithraeum of the Baths of Caracalla (Rome)
(Peer reviewed; Journal article, 2020)The peculiar microclimate inside cultural hypogeal sites needs to be carefully investigated. This study presents a methodology that aimed at providing a user-friendly assessment of the frequently occurring hazards in such ... -
