(Journal article; Peer reviewed, 2018)The Løren tunnel is a road tunnel at Ring road 3 in Oslo, Norway. The tunnel has a length of 915 m in rock, has two tubes with three lanes and breakdown fields, and was first opened in 2013. For rock support in the case ... -
Analysis of the trend of pH changes of concrete pore solution during the hydration by various analytical methods
(Peer reviewed; Journal article, 2022)The pH is an important parameter in concrete health monitoring. Many studies have been conducted to investigate the environmental elements that influence the pH value of concrete. This study focussed on the investigation ... -
Analysis of Thermoacoustic Modes in Can-Annular Combustors Using Effective Bloch-Type Boundary Conditions
(Peer reviewed; Journal article, 2020)Heavy-duty gas turbines are commonly designed with can-annular combustors, in which all flames are physically separated. Acoustically, however, the cans communicate via the upstream located compressor plenum, or at the ... -
An Analysis of Transaction Handling in Bitcoin
(Chapter, 2021)Bitcoin has become the leading cryptocurrency system, but the limit on its transaction processing capacity has resulted in increased transaction fee and delayed transaction confirmation. As such, it is pertinent to understand ... -
Analysis of underwater snake robot locomotion based on a control-oriented model
(Proceedings of the 2015 IEEE Conference on Robotics and Biomimetics;, Journal article; Peer reviewed, 2015)This paper presents an analysis of planar underwater snake robot locomotion in the presence of ocean currents. The robot is assumed to be neutrally buoyant and move fully submerged with a planar sinusoidal gait and limited ... -
Analysis of unlined pressure shafts and tunnels of selected Norwegian hydropower projects
(Journal article; Peer reviewed, 2018)Norwegian hydropower industry has more than 100 years of experiences in constructing more than 4000 km-long unlined pressure shafts and tunnels with maximum static head of 1047 m (equivalent to almost 10.5 MPa) reached at ... -
Analysis of uPort Open, an identity management blockchain-based solution
(Peer reviewed; Journal article, 2020)Recently, academics and professionals proposed a substantial number of identity management solutions based on blockchain technology. Among them, uPort appeared promising, being considered for both personal and administrative ... -
Analysis of wake effects on global responses for a floating two-turbine case
(Journal article; Peer reviewed, 2019)While most existing modeling and analysis of floating wind turbines (FWTs) considers isolated systems, interactions among multiple FWTs arranged in an array have received little attention. In this study, two 10 MW ... -
Analysis of water ingress, grouting effort, and pore pressure reduction caused by hard rock tunnels in the Oslo region
(Peer reviewed; Journal article, 2022)Many subsurface projects in Scandinavia face challenges with settlement risk from water ingress into tunnels, due to challenging ground conditions featuring hard bedrock underlying soft, marine clay deposits. Pore pressure ... -
Analysis of Wear Performance of Two Finger Seal Structure
(Journal article; Peer reviewed, 2021)To reveal the wear law of parabola-shaped and arc-shaped finger seals (FSs), the wear characteristics of parabola-shaped and arc-shaped FSs were studied in this paper. Firstly, a formula for calculating the contact stress ... -
