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 ... -
Accuracy investigation of UAV Photomapping
(Peer reviewed; Journal article, 2017)Drone systems are high-technology products which can also be used for mapping. Drone mapping has recently become very popular for producing orthophoto maps, terrain models and 3D-data over small areas. A test area located ... -
Blockage Correction and Reynolds Number Dependency of an Alpine Skier: A Comparison Between Two Closed-Section Wind Tunnels.
(Peer reviewed; Journal article, 2020)The purpose of this study was to investigate the impact of blockage effect and Reynolds Number dependency by comparing measurements of an alpine skier in standardized positions between two wind tunnels with varying blockage ... -
Collaborative project delivery methods
(Doctoral theses at NTNU;2022:210, Doctoral thesis, 2022)Byggebransjen har historisk sett vært et tøft prosjektbasert marked med lave marginer og høy konkurranse. Etter hvert som teknologien og samfunnet har utviklet seg, har også prosjektene blitt mer komplekse. Samtidig har ... -
Correlation Analysis of Multipath Effects in GPS-Code and Carrier Phase Observations
(Peer reviewed; Journal article, 2010)Multipath error is a limiting factor for successful ambiguity resolution in precise real-time kinematic GPS positioning, both in the carrier phase and pseudorange measurements. Understanding the temporal characteristics ... -
Driver behavior and traffic flow in oversaturated intersections
(Doctoral theses at NTNU;2019:54, Doctoral thesis, 2019)Driver behavior and traffic flow theory has been studied by researchers for decades. However, most of the studies have been aimed towards driving in undersaturated conditions. The research presented in this thesis, on the ... -
An Event-Based Pipeline for Geospatial Vector Data Management
(Doctoral theses at NTNU;2021:17, Doctoral thesis, 2021)Ever since we started exploring the world, information about where things are and how to get there has been valuable and sought-after. The hand-drawn, and later printed, map provided an efficient mechanism for storing and ... -
Experimental investigations on fire performance of the engineered wood products cross-laminated timber and I-joists
(Doctoral theses at NTNU;2024:135, Doctoral thesis, 2024)The building industry has, in recent years, more frequently used different engineered wood products, like cross-laminated timber (CLT), glue-laminated timber and I-joists. The increased popularity is due to the many ... -
Geoid-type surface determination using a gravimetric quasigeoid model and GNSS/leveling data- A case study in eastern Norway
(Peer reviewed; Journal article, 2013)Norway is about to realize a new vertical datum NN2000, which is supposed to replace the present datum NN1954. Norwegian Mapping Authority (NMA) is also realizing a new geodetic reference frame ITRF09, with focus mainly ... -
GRACE-derived ice-mass loss spread over Greenland
(Peer reviewed; Journal article, 2015)The Gravity Recovery and Climate Experiment (GRACE) monthly satellite data is used to examine the extent and magnitude of Greenland ice sheet melting for 2003-2012. We show that the well documented Greenland ice mass loss ... -
Homogenizing GPS Integrated Water Vapor Time Series: Benchmarking Break Detection Methods on Synthetic Data Sets
(Peer reviewed; Journal article, 2020)We assess the performance of different break detection methods on three sets of benchmark data sets, each consisting of 120 daily time series of integrated water vapor differences. These differences are generated from the ... -
Hygrothermal Modeling of Masonry with Interior Insulation Retrofit - Perspectives on hygrothermal performance and modeling-uncertainty
(Doctoral theses at NTNU;2024:43, Doctoral thesis, 2024)Energy retrofit of existing buildings is mainly an endeavor to reduce energy consumption. Interior insulation retrofit of masonry falls among retrofit measures in this regard. However, interior insulation of masonry may ... -
Ice and Ice Forces in Small Steep Rivers
(Doctoral theses at NTNU;2023:431, Doctoral thesis, 2023)English summary Given the right circumstances ice can wreak havoc on riverine infrastructure. Ice runs pushing ice floes against bridge piers is frequently the governing design condition for bridges in cold regions. The ... -
Influence of Gravel-Bed Porosity and Grain Orientation on Bulk Flow Resistance
(Journal article; Peer reviewed, 2018)This paper presents results from experiments that were carried out to study the effect of porosity and grain orientation on flow resistance. Experiments were performed over three rough surfaces; a water-worked gravel-bed, ... -
Influence of large-scale asperities on the stability of concrete dams
(Chapter, 2022)For concrete dams founded on rock, there are only a few options in the common analysis methods to account for large‐scale asperities. However, previous research alludes that they have a significant impact on the behaviour ... -
Investigation of debris flow entrainment and mitigation using flexible barriers. Physical and numerical modelling
(Doctoral theses at NTNU;2022:351, Doctoral thesis, 2022)Debris flows typically increase in scale by entraining soil, fluid, and boulders along the flow channel. Entrainment is typically modelled according to semi-empirical formulations which do not allow to capture the physical ... -
Investigation of Free Surface Turbulence Damping in RANS Simulations for Complex Free Surface Flows
(Journal article; Peer reviewed, 2019)The modelling of complex free surface flows over weirs and in the vicinity of bridge piers is presented in a numerical model emulating open channel flow based on the Reynolds Averaged Navier-Stokes (RANS) equations. The ... -
