Radon barriers: A state-of-the-art review and future opportunities
(Bachelor thesis, 2023)Forskjellige løsninger for radonsperrer har blitt sammenlignet og studert. Kommersielle radonsperrer og andre materialer har blitt satt opp mot hverandre for å vise hvilke av de som kan være velfungerende barrierer. De ... -
RailCheck: A WSN-Based System for Condition Monitoring of Railway Infrastructure
(Chapter, 2018)Contemporary tools used to monitor railway points and crossings are ineffective. Routine inspections of these critical parts are still being performed manually by specially-trained inspectors. This creates higher expenditure ... -

RailCheck: Functional Safety for Wireless Condition Monitoring of Railway Turnouts and Level Crossings
(Chapter, 2019)Increasing demands for more cost-effective, reliable and safer railway infrastructure unavoidably bring up the need for transitioning from current preventive maintenance strategies to more efficient, predictive, condition-based ... -
Railway Ballast Characteristics, Selection Criteria and Performance
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:259, Doctoral thesis, 2014)This work is a comprehensive investigation to find to what extent simple laboratory tests e.g. Los Angeles abrasion and micro-Deval might be suitable for predicting real railway ballast performance with respect to deformation ... -
Railway ballast stabilising agents: Comparison of mechanical properties
(Peer reviewed; Journal article, 2020)Expensive and time-consuming maintenance operations are routinely performed to preserve the ballast mechanical properties in railway lines. Binding agents are used for ballast stabilisation. Four different additives based ... -
Railway bridge damage detection using vehicle-based inertial measurements and apparent profile
(Journal article; Peer reviewed, 2017)The presence of damage in a railway bridge alters its stiffness and consequently, its static and dynamic response to loading. The dynamic response of a railway bridge to loading produces a dynamic response in the passing ... -
Railway catenary tension force monitoring via the analysis of wave propagation in cables
(Peer reviewed; Journal article, 2020)The tensioning forces applied to the contact wire in a railway catenary system influence the performance of the line. In this paper, a method to monitor the status of such tensioning forces is proposed based on the dependency ... -
Railway track loss-of-stiffness detection using bogie filtered displacement data measured on a passing train
(Peer reviewed; Journal article, 2021)This paper presents an innovative numerical framework for railway track monitoring using acceleration measurements from sensors installed on a passenger train. A numerical model including a 10 degrees of freedom train ... -
Rain Attenuation Measurements and Analysis at 73 GHz E-Band Link in Tropical Region
(Peer reviewed; Journal article, 2020)This letter presents the rainfall intensity and rain attenuation analysis in tropical region based on a one-year measurement using the 73.5 GHz E-band link of 1.8 km with three rain gauges installed along the path. The ... -
Rain Intrusion Through Horizontal Joints in Façade Panel Systems - Experimental Investigation
(Master thesis, 2022)Plane plater er vanlig å bruke som fasadekledning på store bygninger i Norden. Fasadeplatene anbefales å monteres med horisontale og vertikale fuger for å tillate temperatur- og fuktbevegelser. De vertikale fugene antas å ... -

Rain Intrusion through Horizontal Joints in Façade Panel Systems - Experimental Investigation
(Peer reviewed; Journal article, 2022)Façade panel systems with horizontal open joints are commonly used on larger buildings in Nordic countries. Excessive water intrusion through open joints may cause deterioration of the façade, a concern exacerbated by ... -
Rain resistance of open-joint facade claddings – Experiences from laboratory measurements
(Peer reviewed; Journal article, 2023)Façade claddings with open joints are commonly used in large buildings in Norway. Plane façade panels of fibre cement and high-pressure laminate boards are usually fabricated using joint width of 5 – 10 mm, while solar ... -
Rain resistance of windows – Lessons learned from two decades of laboratory testing
(Peer reviewed; Journal article, 2023)Windows are important in buildings intended for human activities as they let in daylight and provide views. However, they may also be vulnerable in terms of heat loss, air leaks, rain tightness, and durability. In Nordic ... -

RAM and Safety Analysis of Railway Signalling Systems
(Master thesis, 2010)Demonstrating compliance with RAM and Safety requirements is a prerequisite before railway application products are qualified for their intended application. EN 50126 requires documented evidence which shows how railway ... -
RAM-analysar for jernbaneinfrastruktur
(Master thesis, 2017)Ved bygging av ny jernbaneinfrastruktur, eller betydeleg endring av eksisterande jernbaneinfrastruktur, skal det gjennomførast RAM-analysar. Slike analysar vurderer jernbaneinfrastrukturen si yting, i form av evna den har ... -
Raman antenna effect from exciton–phonon coupling in organic semiconducting nanobelts
(Journal article; Peer reviewed, 2017)The highly anisotropic interactions in organic semiconductors together with the soft character of organic materials lead to strong coupling between nuclear vibrations and exciton dynamics, which potentially results in ... -
