(Doctoral theses at NTNU;2022:386, Doctoral thesis, 2022)Metal cycles form the backbone of our modern societies but are also responsible for a large part of the anthropogenic greenhouse gas (GHG) emissions. The transition towards a more sustainable socio-economic metabolism will ... -
Evaluation of MBTSA technology for CO2 capture from waste-to-energy plants
(Journal article; Peer reviewed, 2022)Moving bed temperature swing adsorption (MBTSA) is a promising technology for CO2 capture from flue gases. In a MBTSA unit, a selective adsorbent material is circulated between a low-temperature stage where it removes CO2 ... -
Towards the “sustainable” operation at -30 °C without the expense of energy for heating on-face electronics: intelligent heat conservation and waste heat utilization
(Journal article; Peer reviewed, 2022)On-face electronics (On-faceE) are urged to sense “anytime, anywhere” for enabling human senses to globally dominate the Internet of Things. However, with the limited lifetime of batteries and the miniaturization of the ... -
Dynamics of collective action to conserve a large common-pool resource
(Peer reviewed; Journal article, 2021)A pressing challenge for coming decades is sustainable and just management of large-scale common-pool resources including the atmosphere, biodiversity and public services. This poses a difficult collective action problem ... -
Efficiency Estimation of Synchronous Generators for Marine Applications and Verification With Shop Trial Data and Real Ship Operation Data
(Journal article; Peer reviewed, 2020)Three methods were explored to estimate the efficiency for the conversion of mechanical power to electrical power using synchronous generators in ships at low power factors. Generally, the generator efficiency data is ... -
Sonochemical dosimetry: A comparative study of Weissler, Fricke and terephthalic acid methods
(Peer reviewed; Journal article, 2021)Acoustic cavitation and sonochemical reactions play a significant role in various applications of ultrasound. A number of dosimetry methods are in practice to quantify the amount of radicals generated by acoustic cavitation. ... -
Solutions for retrofitting existing, wooden houses in cold climates
(Peer reviewed; Journal article, 2020)Upgrading existing one-family houses to higher energy standards can be a challenge for owners, among others, due to the unclear status of technical regulations in the case of retrofitting at the national level. Retrofitting ... -
Inverse problems of the dynamics of observation interpretation systems
(Journal article; Peer reviewed, 2021)Based on the analysis and systematization of the inverse problems of dynamics, the study of the properties and features of the types of dynamic models under consideration, an approach is proposed for the development of ... -
Forearc crustal structure of Ecuador revealed by gravity and aeromagnetic anomalies and their geodynamic implications
(Journal article; Peer reviewed, 2020)Along the Western Cordillera of Ecuador, fault-bounded ophiolites derived from the Late Cretaceous Caribbean Large Igneous Province (CLIP) have provided key petrotectonic indicators that outline the nature and the mechanism ... -
RiskBIM - Risikostyring i BIM-drevne offentlige samferdselsprosjekter
(IFE/E;, Research report, 2022)This report summarizes the main results from the RiskBIM project (Risk management for BIM-driven public transport projects) supported by the Norwegian Research Council. RiskBIM dealt with the use of digital models and BIM ... -
Overheating risk of a typical Norwegian residential building retrofitted to higher energy standards under future climate conditions
(Peer reviewed; Journal article, 2020)Heat waves had attacked Norway in 2018 and 2019. Residents in Norway experienced a very uncomfortable indoor environment in the summer of 2018 and 2019. Few publications on the overheating risk of a typical Norwegian ... -
Experimental and Numerical Determination of the Head Loss of a Pressure Driven Flow through an Unlined Rock-Blasted Tunnel
(Peer reviewed; Journal article, 2020)The friction loss in a part of the rock-blasted unlined tunnel of the Litjfossen hydropowerplant in Norway was determined from experimental and numerical studies. Remote sensing datafrom the prototype tunnel provided the ... -
Enhanced storage stability and rheological properties of asphalt modified by activated waste rubber powder
(Peer reviewed; Journal article, 2021)Segregation of waste crumb rubber powder (WR) modified asphalt binders the large-scale application of WR in asphalt. The method of microwave activation combined with chemical activation (KMWR) was proposed to improve storage ... -
The Influence of Icephobic Nanomaterial Coatings on Solar Cell Panels at High Latitudes
(Peer reviewed; Journal article, 2022)Solar energy’s penetration at high latitudes has been boosted during recent years, but snow deposits during the winter still limit its exploitation. Therefore, various solutions for snow removal, such as icephobic coatings, ... -
Investigation of leaching in steel fiber-reinforced shotcrete exposed to fresh and saline groundwater in a subsea road tunnel
(Peer reviewed; Journal article, 2022)The field and laboratory investigations performed in the Frøya subsea road tunnel, constructed between 1998 and 2000, focus on the degree of leaching undergone by steel fiber-reinforced shotcrete in fresh and saline ... -
Design and Management of Assembly Systems 4.0
(Doctoral theses at NTNU;2022:367, Doctoral thesis, 2022)In recent years, companies have faced great customer demand change involving, for example, a change in colour (aesthetic design), shape (measurement) or technical characteristics of some components (functionality) (Piller, ... -
Assessing the potential of seasonal thermal storage for local energy systems: Case study for a neighborhood in Norway
