R744 Refrigeration Solution for Small Supermarkets
(Chapter, 2021)Application based technology solution is nowadays preferred to achieve the performance of the cooling system configuration at its best. Therefore, benchmarking is an essential criterion which would add value to the optimum ... -
Radial Consolidation of Pore Pressure Induced by Pile Driving
(Master thesis, 2015)Pile installation is recognized to significantly disturb the surrounding clay and cause changes in total and effective stresses around the pile. In this thesis, a numerical model is used to simulate pile installation and ... -
Radial consolidation of pore pressure induced by pile installation
(Master thesis, 2016)The soil surrounding a driven pile is subjected to varying degrees of soil disturbance during the installation, and experiences a complex combination of loading, unloading and reloading in the course of the life cycle of ... -
Radiation therapy and training effects on the mechanical performance of bone
(Master thesis, 2021)Med stadig stigende forventet levealder oppstår nye aldersrelaterte utfordringer. Eksponering for både osteoporotiske brudd og kreft øker med alder, og flere tilfeller oppdages siden ny teknologi for medisinsk undersøkelse ... -
Radiative forcing bias of simulated surface albedo modifications linked to forest cover changes at northern latitudes
(Journal article; Peer reviewed, 2015)In the presence of snow, the bias in the prediction of surface albedo by many climate models remains difficult to correct due to the difficulties of separating the albedo parameterizations from those describing snow and ... -
Radiative forcing geoengineering causes higher risk of wildfires and permafrost thawing over the Arctic regions
(Journal article; Peer reviewed, 2024)Radiative forcing geoengineering is discussed as an intermediate solution to partially offset greenhouse gas-driven warming by altering the Earth’s energy budget. Here we use an Earth System Model to analyse the response ... -
Radio frequency measurements and capacity analysis for industrial indoor environments
(Chapter, 2015)In this study, path-loss and shadowing measurement results for three different industrial indoor environments at 900, 1600, and 2450 MHz are presented. The results show that the one-slope model fits the measured path-loss ... -
Radio Propagation Measurements in the Indoor Stairwell Environment at 3.5 and 28 GHz for 5G Wireless Networks
(Journal article; Peer reviewed, 2020)To cover the high demand for wireless data services for different applications in the wireless networks, different frequency bands below 6 GHz and in millimeter-wave (mm-Wave) above 24 GHz are proposed for the fifth ... -
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: 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 ...
