Role of receiver on the performance of a transcritical CO2 based air-conditioning unit with single-stage and two-stage expansion
(Peer reviewed; Journal article, 2021)Theoretical and experimental studies are carried out on a transcritical CO2 based air-conditioning unit. Two configurations– a system with single-stage expansion (SSE) and a system with two-stage expansion (TSE) have been ... -
The Role of Ship Simulators and Maneuvering Models in Maritime Operations
(Doctoral theses at NTNU;2023:23, Doctoral thesis, 2023)The concept of autonomy in the maritime domain is attractive from both the safety and efficiency points of view, as in other transportation domains. To investigate the payoffs of autonomy as automation levels increase on ... -
The Role of Sustainable Project Management in Facilities Management
(Peer reviewed; Journal article, 2023)Growth in facilities management (FM) and project management (PM) have been remarkable over the last decade. Simultaneously, the adoption of sustainability principles among organisations has also increased. The purpose of ... -
Role of Transient Characteristics in Fish Trajectory Modeling
(Journal article; Peer reviewed, 2020)In this experiment, we analyzed live fish (silver carp) trajectories recorded in an experimental vertical-slot fishway. Combined with a numerical simulation, we demonstrated that randomness shown in fish trajectories might ... -
The Role of Tungsten on the Phase Transformation Kinetics and its Correlation with the Localized Corrosion Resistance of 25Cr Super Duplex Stainless Steels
(Peer reviewed; Journal article, 2020)Super Duplex Stainless Steels (SDSS) have excellent corrosion resistance due to their high concentration of alloying elements like Cr, Mo, and N. There is still, however, disagreement on the role of tungsten in the corrosion ... -
Roll Damping Investigation of Two-Dimensional Ship Section with Bilge-Boxes
(Master thesis, 2017)Roll motion is considered as one of the most difficult responses to be mathematically treated, this is due to the importance of the viscous effects. Several parameters may affect the roll motion hydrodynamically. Hence, ... -
Roll damping of a surface effect ship with split air cushion
(Journal article; Peer reviewed, 2018)This paper considers linear modeling of a surface effect ship (SES) where roll motions are damped by exclusively exploiting a longitudinally split air cushion design. On a SES, the pressurized air cushions can support up ... -
Roll-yaw coupling effects on parametric resonance for a ship in regular waves
(Chapter, 2014)This work represents a further step of the physical study documented by Greco and Lugni (2012b) and Greco et al. (2014). Three-dimensional experiments have been performed on a FPSO model in regular waves to investigate the ... -

Roller Skis Assembly Line Learning Factory – Development and Learning Outcomes
(Journal article; Peer reviewed, 2017)This paper describes the process of creating a learning factory based on an assembly line of roller skis used in order to enhance students’ practical and theoretical knowledge on topics of kaizen, waste types, efficiency, ... -
Rolling Out the Anthropogenic Aluminum Cycle: With Foci on Temporal, Geographical, and Emission Perspectives
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:95, Doctoral thesis, 2013)Anthropogenic metal cycles today confront three interconnected large challenges: an increasing global demand due to rising population and escalating industrialization and urbanization, a profound change of the global supply ... -
Rolling Resistance Measurements on Cycleways Using an Instrumented Bicycle
(Peer reviewed; Journal article, 2021)Snow and ice on roads often lead to increased rolling resistance that makes roads less accessible and less attractive for cyclists. Introducing a minimum requirement for rolling resistance in winter maintenance of cycleways ... -
Rom for innovasjon i veidriftskontrakter
(Master thesis, 2019)Statens vegvesen har siden 2003 lagt drift og vedlikehold av riks- og fylkesveiene ut på anbud. Veinettet er delt inn ca. 105 i geografiske kontraktsområder, og det er disse driftsentreprenørene kan konkurrere om. Når en ... -
Romkurve i vegplanlegging
(Bachelor thesis, 2019)I den norske vegnormalen per 2019 finnes det ingen krav om romkurve i vegplanlegging. Selv om dette tidligere var en del av vegnormalen, ble det etter hvert flyttet over i en egen veiledningshåndbok. Hensikten med oppgaven ... -
Romlig mineralogisk og geofysisk karakterisering av Nabberen nefelinsyenittforekomst - Med utgangspunkt i definerte geokjemiske domener og med fokus på forekomsten av magnetitt
(Master thesis, 2016)Sommeren 2015 ble det gjort undersøkelser i gruven til Sibelco Nordic AS. Nabbaren Nefelinsyenitt, som blir undersøkt i oppgaven, er lokalisert på sør-siden av Stjernøya, nord-vest for Alta. Bedriften har delt forekomsten ... -
Romoppvarming i lavenergi kontorbygninger
(Master thesis, 2012)Denne oppgaven omhandler et plenumbasert omrøringsventilasjon løsning. Dette plenumbaserte ventilasjonssystemet er utstyrt med en perforert aluminiumshimling med en lufttett akustisk duk og en innfelte diffusor i himlingplaten. ... -
