Well-Log Database and Automation of Well Log Depth Matching by Using Analytical Methods and Deep Learning
(Doctoral theses at NTNU;2022:104, Doctoral thesis, 2022)Well log data formats remain rigid, outdated, and difficult to understand and to work with. The amount of available documentation is limited, thus much of the valuable information held in these data formats is left behind ... -
A numerical geotechnical model for computing soil slides at banks of water reservoirs
(Peer reviewed; Journal article, 2020)Soil slides can occur when the water level in a lake or a reservoir is lowered. This may take place in situations when a reservoir is flushed to remove sediments. The current study describes a three-dimensional numerical ... -
The influence of Fischer–Tropsch-biodiesel–diesel blends on energy and exergy parameters in a six-cylinder turbocharged diesel engine
(Peer reviewed; Journal article, 2020)This investigation explores the influence of oxygenated fuels on different energy and exergy parameters first and the second law of thermodynamics. The parameters were estimated based on the experimental data using ... -
Risikostyring av kvalitetskostnader
(Master thesis, 2022)Kvalitetsavvik utgjør en betydelig andel av kostnader i byggeprosjekter. Likevel legges det i liten grad vekt på kvalitetsavvik og tilhørende kostnader i endringsarbeider. Det faktiske omfanget av kvalitetskostnader viser ... -
Life Cycle Assessment of Concrete from Bauxite Residue in China
(Master thesis, 2021)For tiden er miljøproblemet mye bekymret av samfunnet; og industrien har blitt avslørt som en stor bidragsyter av forskere. Selv om det er nyttig å lindre det med å "redusere" industriavfallet, vil det ikke være uendelig ... -
A Hybrid Method to Incrementally Extract Road Networks Using Spatio-Temporal Trajectory Data
(Peer reviewed; Journal article, 2020)With the rapid development of urban traffic, accurate and up-to-date road maps are in crucial demand for daily human life and urban traffic control. Recently, with the emergence of crowdsourced mapping, a surge in academic ... -

The Casimir effect for fermionic currents in conical rings with applications to graphene ribbons
(Peer reviewed; Journal article, 2020)We investigate the combined effects of boundaries and topology on the vacuum expectation values (VEVs) of the charge and current densities for a massive 2D fermionic field confined on a conical ring threaded by a magnetic ... -
Gone With the Wind? Offshore Wind Data Management in the North Sea
(Master thesis, 2022)Havvind sees på som en levedyktig løsning for fornybar energiproduksjon i stor skala. Norsk økonomisk sone er et område godt egnet for flytende og bunnfaste turbiner, med gunstig vær, etterspørsel og industriell kompetanse. ... -
Assessment of government debt security of emerging markets: theory and practice
(Peer reviewed; Journal article, 2020)This study came to inspect a new approach to the government debt security assessment based on the systematization of indicators in terms of four directions: solvency, liquidity, domestic indebtedness, and external indebtedness. ... -
A methodology to analyze sustainable development index: evidence from emerging markets and developed economies
(Peer reviewed; Journal article, 2020)The paper proposes a new approach for dealing with uncertainties in determining the level of sustainability at the national scale. Composite Sustainable Development Index (SDI) is a tool designed to assess comprehensively ... -
Strukturovervåkning av Terrengsykkel
(Master thesis, 2022)En tilnærming for implementering av en sanntids digital-tvilling (DT) basert strukturell helse overvåking (SHO) av sykkelrammer presenteres i denne oppgaven. Det primære målet er å etablere et IT-system som kan støtte SHO ... -
One the use of Machine Learning in the design of structures.
(Master thesis, 2022)FE-analyse kan tilnærmes på en maskin-lærings måte. Man kan tolke simuleringene som input til nevrale netverks modeller og forsøke å predikere en eller flere output. Denne masteroppgaven utforsker hvor godt modellene ... -
Investigation of Solar Photovoltaic-Thermal (PVT) and Solar Photovoltaic (PV) Performance: A Case Study in Ghana
(Peer reviewed; Journal article, 2020)The main objective of this paper is to experimentally assess the real-life outdoor performance of a photovoltaic-thermal (PVT) module against a conventional photovoltaic (PV) system in a hot humid tropical climate in Ghana. ... -
The plate spacing of sea ice
(Peer reviewed; Journal article, 2020)Columnar sea ice grows with an interface of tiny parallel ice plates, the distance of which is known as plate spacing. While it has been proposed as a fundamental microstructure scale of sea ice, the physics behind its ... -
The graphite occurrences of Northern Norway, a review of geology, geophysics, and resources
(Peer reviewed; Journal article, 2020)There are three provinces in Northern Norway in which occurrences of graphite are abundant; the Island of Senja, the Vesterålen archipelago, and the Holandsfjorden area. From these provinces, we report graphite resources ... -
