New approaches to solar tracking and concentration through numerical optimization of lens arrays
(Doctoral theses at NTNU;2020:405, Doctoral thesis, 2020)Solar concentrators are essential for enabling several solar energy applications, including high-efficiency photovoltaic conversion and high-temperature solar thermal energy. These concentrators require accurate solar ... -
Modelica Component Models for Non-diffracting Floating Objects and Quasi-static Catenary Moorings
(Chapter, 2020)In this paper, the theory behind determining the hydrodynamic response of a floating object in the presence of waves is discussed, followed by a simplification for the case of wave-transparent objects. The Morison equation ... -
Modelica Component Models for Oceanic Surface Waves and Depth Varying Current
(Chapter, 2020)In this paper, the theory of progressive ocean-surface gravity-waves is discussed, followed by the concept of the representation of the irregular sea-state by a sea spectrum. Fourier series decomposition of the irregular ... -
An Efficient Production Transfer Process

Theories and Mechanism of Rapid Phase Transition
(Peer reviewed; Journal article, 2020)Light hydrocarbons and hydrogen can replace high-alkane fuels with the benefit of reduced CO2 emissions. Their liquefaction to a cryogenic state is one of the most suitable solutions for storage and transport. An unexpected ... -
Multi-decadal variability in the snow-cover reconstruction at Parma Observatory (northern Italy, 1681-2018 CE)
(Peer reviewed; Journal article, 2020)Emerging negative trends in snow depth and cover days highlight the challenges posed by changing snow patterns around the world. They suggest that snow-dependent regions in southern Europe could be affected by these changes ... -
An Early mid-Latitude Aurora Observed by Rozier (Beziers, 1780)
(Peer reviewed; Journal article, 2020)Aurora observations are an uncommon phenomenon at low and mid latitudes that, at the end of the 18th century, were not well known and understood. Low and mid geomagnetic latitude aurora observations provide information ... -
Subsea Oil Spill Risk Management Based on Sensor Networks
(Peer reviewed; Journal article, 2020)The use of Wireless Sensor Networks (WSNs) in support of Dynamic Risk Assessment regarding oil spills still lacks a proper integration. WSNs enable prompt responses to such emergencies through an appropriate inspection, ... -
Effects of Wind-Wave Misalignment on a Wind Turbine Blade Mating Process: Impact Velocities, Blade Root Damages and Structural Safety Assessment
(Peer reviewed; Journal article, 2020)Most wind turbine blades are assembled piece-by-piece onto the hub of a monopile-type offshore wind turbine using jack-up crane vessels. Despite the stable foundation of the lifting cranes, the mating process exhibits ... -
Bringing Reality Back to Virtual Reality - A Collaborative Tool for Multidisciplinary Teams
(Chapter, 2020)The use of Virtual Reality (VR) supports larger strategic goals in the industry, including the geographically diverse working markets, large-scale projects and increased collaboration, both locally and globally. At the ... -

Examination of the Effect on Tungsten on the Corrosion Properties of 25% Cr Super Duplex Stainless Steel by Advanced Electrochemical Techniques
(Doctoral theses at NTNU, 2020:329, Doctoral thesis, 2020)In this thesis, the effect of Tungsten (W) on localized corrosion resistance of 25Cr super duplex stainless steel (SDSS) was investigated. Firstly, the effect of W on precipitation kinetics of intermetallic phases in SDSS ... -
The effect of surface roughness and topography on the organic coating/steel interface stability
(Doctoral theses at NTNU;2020:304, Doctoral thesis, 2020)The study in this thesis, focused on the effect of surface roughness and topography on the organic coating/steel interface stability in humid air and corrosive conditions. A strong correlation between roughness, Rz, and ... -
Architectural quality and cultural heritage values in economic analysis
(Peer reviewed; Journal article, 2020)This article examines the evaluation of architectural quality in socioeconomic analyses of large public building projects in Norway. From a socio-economic perspective, a new building can be designed well or even better ... -
Samspill i bygg- og anleggsprosjekter: teori og praksis
(Chapter, 2020)Samspill som kontraktstrategi har, i litteraturen, en rekke definisjoner. Mangfoldet av definisjoner gjør det vanskelig å konkretisere hva samspill egentlig er. Denne studien vil ta for seg hvordan samspill beskrives i ... -
Towards mobile and intelligent railway transport: a review of recent ERTMS related research
(Journal article; Peer reviewed, 2020)The development of the European Railway Traffic Management System (ERTMS) throughout Europe over the last two decades to remove obstacles to providing an interoperable railway network has been facing several challenges. ... -
Research directions regarding the adoption of formal methods in the railway signaling sector: determinants and next steps for future-proof railways
(Journal article; Peer reviewed, 2020)The terms Formal Methods (FMs) refer to a set of techniques and software toolkits that, based on mathematical rigor, can enhance safety, security, and the efficient operation of a wide range of systems. Considering that ... -
Calibration Method for monitoring hygro-mechanical reactions of coated and uncoated pine and oak wood by Acoustic Emission Non-Destructive Testing
(Peer reviewed; Journal article, 2020)The main issue of wood is its sensitivity to Relative Humidity (RH) variations, affecting its dimensional stability, and thus leading to crack formations and propagations. In situ structural health monitoring campaigns ... -
