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 ... -

(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 ... -
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 ... -
Computation of three-dimensional three-phase flow of carbon dioxide using a high-order WENO scheme
(Journal article; Peer reviewed, 2017)We have developed a high-order numerical method for the 3D simulation of viscous and inviscid multiphase flow described by a homogeneous equilibrium model and a general equation of state. Here we focus on single-phase, ... -
Computational and Experimental Druggability Assessment of Human DNA Glycosylases
(Peer reviewed; Journal article, 2019)Due to a polar or even charged binding interface, DNA-binding proteins are considered extraordinarily difficult targets for development of small-molecule ligands and only a handful of proteins have been targeted successfully ... -
Computational Fluid Dynamics Reproduction of Nonlinear Loads on a Vertical Column during Extreme Irregular Wave Events
(Journal article; Peer reviewed, 2018-07-12)Recently, a method for numerical reproduction of measured irregular wave events has been developed. The measured motion of the wave maker flaps defines the wave kinematics at the boundary of the numerical simulation in ... -
A computational iterative design method for bend-twist deformation in composite ship propeller blades for thrusters
(Journal article; Peer reviewed, 2023)This study investigates the feasibility of utilising common composite material layup techniques in ship propeller blade design to achieve an automatic pitch adjustment through bending-induced twist deformation. A comprehensive ... -
