Top-down spatially-explicit probabilistic estimation of building energy performance at a scale
(Peer reviewed; Journal article, 2021)Achieving the energy-related and environmental targets for nations and municipalities is largely dependent on the existing built stock. It plays a pivotal role in the accomplishment of these targets through the implementation ... -
Top-down versus bottom-up project appraisal processes, and external review - Evidence from Norway and China
(Journal article; Peer reviewed, 2013)Project appraisal plays an important role in choosing the right project and is crucial for the success of public investment projects. Different factors may affect the choice of appraisal process in different countries. By ... -
Topics in dynamic positioning: System identification, GNSS and MRU lever arm estimation, and hybrid integral action
(Master thesis, 2014)This thesis consists of three main parts. The first part of the master thesis looks at the identification of thruster dynamics and low speed ship dynamics. The relevant parameters identified are time constants and time ... -
Topics in Production Systems Modeling: Separation, Pumping and Model Based Optimization
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:180, Doctoral thesis, 2014)This thesis addresses three distinct topics within oilfield production technology: 1) Inline oil-water separation for subsea applications, 2) Model based constrained optimization for production networks of high water cut ... -
Topics on Integrated Asset Modelling, Production Systems Boosting and Virtual Metering
(Doctoral thesis at NTNU;2015:293, Doctoral thesis, 2015)This thesis addresses four existing gaps and missing facilities in the route to improve the capabilities to model an entire oil and gas field extending from the reservoir to the field sales point. Such a model, referred ... -
Topo-Bathymetric LiDAR for Hydraulic Modeling - Evaluation of LiDAR Data From Two Rivers
(Master thesis, 2016)Hydraulic modeling is a tool that is widely used for studying rivers to find water depth, velocity, wave propagation, water level variations and other hydraulic variables. To achieve accurate results it is often necessary ... -

Topographic Effect in the Selection of Unlined Pressure Tunnels / Shafts - A Review of a case from Nepal Himalaya
(Chapter, 2017)The design principle behind unlined pressure tunnels/shafts is that the minimum principle stress should be higher than the hydrostatic head acting on the periphery of tunnel/shaft. So, reliable estimation of in-situ stresses ... -
A topographic hinge-zone divides coastal and inland ice dynamic regimes in East Antarctica
(Peer reviewed; Journal article, 2023)The impact of late Cenozoic climate on the East Antarctic Ice Sheet is uncertain. Poorly constrained patterns of relative ice thinning and thickening impair the reconstruction of past ice-sheet dynamics and global sea-level ... -
Topography studies of concrete abraded with ice
(Journal article; Peer reviewed, 2019)Topography studies of concrete-ice abrasion were made to proceed in our understanding of the mechanisms of concrete wear by ice on Arctic offshore structures. The effects on various initial surfaces of a B75 normal-weight ... -
Topology and Parametric Optimization-Based Design Processes for Lightweight Structures
(Peer reviewed; Journal article, 2020)Topology and Parametric Optimization are two of the most implemented material optimization approaches. However, it is not clear in the literature which optimization procedure, or possible combination of them, can lead to ... -
Topology and polarity of dislocation cores dictate the strength of monolayer MoS2
(Journal article; Peer reviewed, 2019)In contrast to homoelemental graphene showing common dislocation dipole with pentagon-heptagon (5|7) core, heteroelemental MoS2 is observed to contain diverse dislocation cores that tune the chemical and physical properties. ... -
Topology optimised bolt placements
(Master thesis, 2021)This thesis will focus on the use of optimization algorithms to suggest an optimal bolt placement with regards to deflection. The work is inspired by and supposed to be an addition to the design process that Thomas Røkke ... -
Topology optimization and dimensioning of a subtractively manufactured Formula Student wheel assembly
(Master thesis, 2022)En av de største kildene til ytelsestap i racing er manglende stivhet i strukturelle komponenter. Manglende stivheter i hjulopphenget representerer avvik fra optimal posisjon og tap av lateral akselerasjon. Strukturelle ... -
Topology Optimization in Mechanical Engineering: Implementation and practical aspects
