Composite Material Recycling Technology—State-of-the-Art and Sustainable Development for the 2020s
(Peer reviewed; Journal article, 2021)Recently, significant events took place that added immensely to the sociotechnical pressure for developing sustainable composite recycling solutions, namely (1) a ban on composite landfilling in Germany in 2009, (2) the ... -
COMPOSITE: A concept for high efficiency power production with integrated CO2 capture from solid fuels
(Peer reviewed; Journal article, 2017)The COMPOSITE concept combines packed bed chemical looping combustion (PBCLC) with chemical looping for oxygen production (CLOP) in an integrated gasification combined cycle for high efficiency power production. Detailed ... -
Composition analysis and minimal treatments to solubilize 6 polysaccharides from the brown seaweed Laminaria digitata 7 for microbial growth of thermophiles
(Peer reviewed; Journal article, 2020)Brown macroalgae (Phaeophyta) hold high potential as feedstock for biorefineries due to high biomass productivity and carbohydrate content. They are, however, a challenging, unconventional feedstock for microbial refining ... -
Composition and Structure Analysis of Hard Grey Scale (HGS) Formed on Cold Surfaces Exposed to Aluminium Production Off-gas
(Peer reviewed; Journal article, 2022)Hard grey scale (HGS) is a strongly adhering fouling material forming on solid surfaces impinged by off-gas generated in the pot cells of primary aluminium production plants. Even though associated maintenance costs have ... -
Compositional and structural properties of pulsed laser-deposited ZnS:Cr films
(Peer reviewed; Journal article, 2016)We present the properties of Cr-doped zinc sulfide (ZnS:Cr) films deposited on Si(100) by pulsed laser deposition. The films are studied for solar cell applications, and to obtain a high absorption, a high Cr content ... -
Compositional Refinement of Policies in UML – Exemplified for Access Control
(Research report, 2009)The UML is the de facto standard for system specification, but offers little specialized support for the specification and analysis of policies. This paper presents Deontic STAIRS, an extension of the UML sequence diagram ... -
Comprehending Feature Models Expressed in CVL
(Journal article; Peer reviewed, 2014)Feature modeling is a common way to present and manage variability of software and systems. As a prerequisite for effective variability management is comprehensible representation, the main aim of this paper is to investigate ... -
Comprehensive assessment of CCS chains–Consistent and transparent methodology
(Peer reviewed; Journal article, 2011)Through combining insights from engineering, natural sciences, economics, and political science, one consistent, transparent, and comprehensive analytical framework for assessing and evaluating various CCS chains is ... -
Comprehensive Char Particle Gasification Model Adequate for Entrained-Flow and Fluidized-Bed Gasifiers
(Journal article; Peer reviewed, 2017)A robust, single-particle gasification model is presented that is capable of predicting char particle behavior in environments established in typical fluidized bed and entrained flow gasifiers. It employs a heterogeneous ... -
Comprehensive classifications and characterizations of power system flexibility resources
(Peer reviewed; Journal article, 2021)Due to the increasing integration of renewable forms of generation, ageing network infrastructure, and rapid increase in peak load demand, flexibility is becoming economically more viable and hence significant role player ... -
Comprehensive Compositional Study of Torrefied Wood and Herbaceous Materials by Chemical Analysis and Thermoanalytical Methods
(Journal article; Peer reviewed, 2016)In this work, the torrefaction of three biomass materials, black locust wood, wheat, and rape straw, was studied at various temperatures: 200, 225, 250, 275, and 300 °C. The thermal stability and formation of the decomposition ... -

A Comprehensive Framework for Vulnerability Analysis of Extraordinary Events in Power Systems
(Peer reviewed; Journal article, 2020)Electric power systems are critical infrastructures subject to the possibility of extraordinary events with high societal consequences. Although such possibilities are often associated with very low probabilities of being ... -
COMPREHENSIVE MODEL FOR BLAST FURNACE USING OPENFOAM®
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)Blast furnace is a complex, multi-phase and high temperature reactor involving multiple reactions between phases, heat transfer and phase change. Limited options are available to know internal state of the furnace through ... -
A Comprehensive Simulator for Hydropower Investment Decisions
(Chapter; Peer reviewed, 2022)Due to a higher share of power production from renewable sources with high short-term variation, hydro systems must more often operate closer to their components' physical limits. To simulate system behaviour, a hydropower ... -
Comprehensive Two-Dimensional Gas Chromatography with Peak Tracking for Screening of Constituent Biodegradation in Petroleum UVCB Substances
(Peer reviewed; Journal article, 2023)Petroleum substances, as archetypical UVCBs (substances of unknown or variable composition, complex reaction products, or biological substances), pose a challenge for chemical risk assessment as they contain hundreds to ... -
Compression stress relaxation in carbon black reinforced HNBR at low temperatures
(Peer reviewed; Journal article, 2017)Findings of a study of stress relaxation behaviour of hydrogenated nitrile butadiene rubber (HNBR) at nominal compressive strains up to 0.4 and temperatures above and below the glass transition temperature Tg are reported. ... -
Compressor Surge Control Using Lyapunov Neural Networks
(Peer reviewed; Journal article, 2020)In this paper surge control in a compression system using a close-coupled valve (CCV) is proposed. The control design is based on Lyapunov control theory in combination with neural networks (NNs) and focuses on minimization ... -
