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 ... -

Analysis on one-off subsidy for renewable energy projects based on time value of money
(Journal article; Peer reviewed, 2019)Due to the incentive policies of governments, renewable energy plays an increasingly important role in the global energy supply system. Among the subsidy schemes, the one-off subsidy is mainly applied in the projects with ... -
Analysis on Shift of Nature Modes of Liquid Sloshing in a 3D Tank Subjected to Oblique Horizontal Ground Motions with Damping Devices
(Journal article; Peer reviewed, 2013)The extended study of Wu et al. (2012) of sloshing fluid in tanks with internal structures from 2D to 3D is presented in the paper. The phenomenon of liquid sloshing in a 3D tank with various damping devices is solved by ... -
Analysis on the Dynamics of Burst Debris Flood at the Inclined Pressure-Shaft of Svandalsflona Hydropower Project, Norway
(Journal article; Peer reviewed, 2014)Longterm stability of the waterway system of the hydropower plants is crucial and should not be underestimated. The compromise may result in severe economic consequences related to revenue loss caused by the plant closedown ... -
Analysis on the pre-injection grout consumption at Strindheim Road Tunnel Project, Trondheim, Norway
(Chapter, 2014)The improvement of road quality by introducing a road tunnel is one of the principles used in both urban areas and other major highway system in Norway. In general, due to good quality rocks, the tun-nels constructed here ... -
Analysis on the relationship between layout and consumption of face cutters on hard rock tunnel boring machines (TBMs)
(Journal article; Peer reviewed, 2018)The consumption of TBM disc cutters is influenced by the ground conditions (e.g. intact rock properties, rock mass properties, etc.), the TBM boring parameters (e.g. thrust, RPM, penetration, etc.) and the cutterhead design ... -
Analysis, occurrence and removal efficiencies of organophosphate flame retardants (OPFRs) in sludge undergoing anaerobic digestion followed by diverse thermal treatments
(Peer reviewed; Journal article, 2023)Organophosphate flame retardants (OPFRs) are a complex group of contaminants to deal with in sewage sludge, as currently there is a lack of robust analytical methods to measure them and management strategies to remove them. ... -
Analytical and FEM Calculation of Electrical Parameters of Carbon Steel Pipe in DEH Systems
(Chapter, 2018)In Direct Electrical Heating (DEH) systems, the pipeline of subsea oil productions conducts a large AC current to generate heat. To further improve the effectiveness of the DEH, higher operating frequency is preferable. ... -
Analytical and numerical approaches to modelling severe plastic deformation
