Dynamic Risk Analysis from the Perspective of Life Cycle Approach in Iec 61508 and Iec 61511
(Peer reviewed; Journal article, 2021)Dynamic risk analysis (DRA) aims to provide updated risk levels during operations of a hazardous facility. One of the main objectives of performing a DRA is to support day-to-day operational decisions, primarily for ... -
Dynamic Risk Analysis of Operation of the Autonomous Underwater Vehicle (AUV)
(Chapter, 2020)The autonomous underwater vehicle (AUV) plays an essential role in scientific research and offshore exploration. Numerous risk issues exist during operation, however, which makes the AUV mission risky. The operating ... -
Dynamic risk assessment in healthcare based on Bayesian approach
(Journal article; Peer reviewed, 2019)Risks related with healthcare are always dynamic, and they are affected by situations of patients, human errors in treatment and even the states of medical devices. This paper proposes a dynamic medical risk assessment ... -
Dynamic risk assessment of marine systems
(Chapter, 2015)Challenges related to risk assessment of dynamic systems have become more numerous in the past decades due to rapid advances in technology. With these advances follows an increased use of automatic control systems which ... -
Dynamic rock support in burst-prone rock masses
(Chapter, 2018)Rockburst occurs in hard and strong rock after excavation when the in situ rock stresses are high. The “driving force” for rockburst is the energy released from the rock mass. The released strain and seismic energy is ... -
Dynamic Safety Constraints by Scenario Based Economic Model Predictive Control
(Chapter, 2014)This paper studies use of scenario based model predictive control (MPC) to control a plant into a fault-tolerant state set. For some systems it is not always sufficient that the controller is reconfigured after a fault, ... -
Dynamic Safety Constraints by Scenario Based Economic Model Predictive Control of Marine Electric Power Plants
(Journal article; Peer reviewed, 2016)This paper studies scenario-based model predictive control (MPC) for dynamic safety constraints. For marine electric power plant with direct current distribution and variable speed generator set, the speed of the generator ... -
Dynamic segment criticality analysis: A precursor to scheduling of maintenance routines in water distribution networks
(Peer reviewed; Journal article, 2022)This study proposes a framework for dynamic segment criticality analysis and its implications on scheduling of some reactive maintenance routines in water distribution networks (WDNs). The framework harmonises multilayer ... -
Dynamic setup of IPsec VPNs in service function chaining
(Journal article; Peer reviewed, 2019)This article describes a novel mechanism for the automated establishment of dynamic Virtual Private Networks (VPN) in the application domain of Network Function Virtualization (NFV). Each hop in an NFV Service Function ... -
Dynamic Simulation and Control of an Active Roll Reduction System Using Free-Flooding Tanks With Vacuum Pumps
(Journal article; Peer reviewed, 2018)Ship roll motion is critical for offshore operations due to its lack of damping mechanism. This paper demonstrates a dynamic simulation scheme of an active roll reduction system using free-flooding tanks controlled by ... -
Dynamic Simulation and Control of an Active Roll Reduction System Using Free-Flooding Tanks With Vacuum Pumps
(Chapter; Peer reviewed, 2017)Ship roll motion is often the critical factor for offshore operations due to its lack of damping mechanism. This paper demonstrates a dynamic simulation scheme of an active roll reduction system using free-flooding tanks ... -
Dynamic simulation and parametric analysis of solar assisted desiccant cooling system with three configuration schemes
(Journal article; Peer reviewed, 2020)Evaporative cooling of the dehumidified air in a desiccant cooling system with the aid of solar energy is an attractive energy saving option to cool the process air for air conditioning purposes. This paper is concerned ... -
Dynamic Simulation of a Mooring Catenary Based on the Lumped-Mass Approach: OpenModelica and Python Implementations
(Chapter, 2020)In this paper, the theoretical background behind the formulation and solution of a discretized lumped-mass mathematical-model of the physically continuous and inelastic mooring catenary is re-visited. The drag term of the ... -
Dynamic simulation of simultaneous HVDC contingencies relevant for vulnerability assessment of the nordic power system
(Chapter, 2019)Large power-infeed of individual HVDC interconnectors may make the power system vulnerable to contingencies involving multiple HVDC interconnectors. This paper describes and demonstrates an approach to quantitative ... -
Dynamic spending and portfolio decisions with a soft social norm
(Peer reviewed; Journal article, 2023)We explore the implications of a preference ordering for an investor-consumer with a strong preference for keeping consumption above an exogenous social norm, but who is willing to tolerate occasional dips below it. We do ... -
Dynamic stochasticmodeling for adaptive sampling of environmental variables using an AUV
(Peer reviewed; Journal article, 2023)Discharge of mine tailings significantly impacts the ecological status of the sea. Methods to efficiently monitor the extent of dispersion is essential to protect sensitive areas. By combining underwater robotic sampling ... -
Dynamic strain ageing in an AlMg alloy at different strain rates and temperatures: Experiments and constitutive modelling
(Peer reviewed; Journal article, 2022)Uniaxial tension tests at strain rates from to and temperatures from 298 to 418 K are performed to study the dynamic strain ageing (DSA) of an AA5182-O sheet. Digital image correlation (DIC) is used to obtain the stress-strain ... -
Dynamic Systems Approach in Sensorimotor Synchronization: Adaptation to Tempo Step-Change
