A framework for estimating information security risk assessment method completeness: Core Unified Risk Framework
(Journal article; Peer reviewed, 2017)In general, an information security risk assessment (ISRA) method produces risk estimates, where risk is the product of the probability of occurrence of an event and the associated consequences for the given organization. ... -
A Framework for Fault Diagnosis in Managed Pressure Drilling Applied to Flow-Loop Data
(Journal article; Peer reviewed, 2013)Data from a medium-scale horizontal flow loop test facility is used to test fault diagnosis in managed pressure drilling. The faults are downhole incidents such as formation influx, fluid loss, drillstring washout, pack-off, ... -
A Framework for the Validation of Network Artifacts
(Journal article; Peer reviewed, 2019) -
A full-scale 3D Vs 2.5D Vs 2D analysis of flow pattern and forces for an industrial-scale 5MW NREL reference wind-turbine
(Journal article; Peer reviewed, 2017)NREL 5MW reference turbine, which is a popular, realistic and standardized industrial scale offshore turbine model, is used in this work for understanding the associated flow-complexities and for testing models. For such ... -
A fully differential capacitively-coupled high CMRR low-power chopper amplifier for EEG dry electrodes
(Journal article; Peer reviewed, 2020)The use of dry electrodes is increasing rapidly. Since their impedance is high, there is a high impedance node at the connecting node between the electrode and amplifier. This leads to absorb powerline signal and high CMRR ... -
A fully implicit WENO scheme on stratigraphic and unstructured polyhedral grids
(Journal article; Peer reviewed, 2019)Many authors have used higher-order spatial discretizations to reduce numerical diffusion, which can be particularly pronounced when simulating EOR processes involving active chemical substances that are transported by ... -
A GA-Based Adaptive Neuro-Fuzzy Controller for Greenhouse Climate Control System
(Journal article; Peer reviewed, 2018)In this research paper, a new application of Adaptive Neuro-Fuzzy Inference System (ANFIS) to the control of greenhouse climate system is introduced. To cope with the large amount of uncertainties present in such systems ... -
A generic framework for power system flexibility analysis using cooperative game theory
(Journal article; Peer reviewed, 2017)Electricity grid infrastructures provides valuable flexibility in power systems with high shares of variable supply due to its ability to distribute low-cost supply to load centers (spatial), in addition to interlinking a ... -
A Generic Study on Green IT/IS Practice Development in Collaborative Enterprise: Insights from a Developing Country
(Journal article; Peer reviewed, 2020)This study investigates the perception of Information Technology (IT) professionals and IT managers towards deployment of environmental-friendly practices in Collaborative Enterprise (CE). Through literature review this ... -
A Geometric Approach to the Design of Serial and Parallel Manipulators with Passive Joints
(Journal article; Peer reviewed, 2014)The use of robotic manipulators in remote and sensitive areas calls for more robust solutions when handling joint failure, and the industry demands mathematically robust approaches to handle even the worst case scenarios. ... -
A Gray-Box Method for Stability and Controller Parameter Estimation in HVDC-Connected Wind Farms Based on Nonparametric Impedance
(Journal article; Peer reviewed, 2019)Estimation of critical control parameters is a desirable tool feature for stability analysis and impedance shaping of high voltage dc (HVdc) connected wind farms. Accurate estimation of such parameters would be enabled by ... -
A Guideline for Game Development-Based Learning: A Literature Review
(Journal article; Peer reviewed, 2012)This study aims at reviewing the published scientific literature on the topics of a game development-based learning (GDBL) method using game development frameworks (GDFs) with the perspective of (a) summarizing a guideline ... -
A heat equation for freezing processes with phase change: stability analysis and applications
(Journal article, 2016)In this work, the stability properties as well as possible applications of a partial differential equation (PDE) with state-dependent parameters are investigated. Among other things, the PDE describes freezing of foodstuff, ... -
A Holistic Study on Green IT/IS Practices in ICT Departments of Collaborative Enterprise: A Managerial and Practitioners Perspective
(Journal article; Peer reviewed, 2020)The purpose of this article is to identify various drivers which influence the information communication technology (ICT) departments of collaborative enterprises (CEs) to infuse green information technology (Green IT) and ... -
A homotopy-based moving horizon estimation
(Journal article; Peer reviewed, 2019)Moving horizon estimation (MHE) solves a constrained dynamic optimisation problem. Including nonlinear dynamics into an optimal estimation problem generally comes at the cost of tackling a non-convex optimisation problem. ... -

A hybrid approach to underwater docking of AUVs with cross-current
(Journal article, 2016)This paper proposes a docking maneuver for an underactuated autonomous underwater vehicle (AUV) to dock into a funnel shaped docking station. The novelty of the proposed approach is enabling an underactuated AUV that is ... -
A hybrid model of obstacle-aided snake robot locomotion
(Journal article; Peer reviewed, 2010)A snake can traverse cluttered and irregular environments by using irregularities around its body as push-points to aid the propulsion. This characteristic feature of biological snake locomotion, denoted obstacle-aided ... -
A hybrid social influence model for pedestrian motion segmentation
(Journal article; Peer reviewed, 2018)A hybrid social influence model (HSIM) has been proposed which is a novel and automatic method for pedestrian motion segmentation. One of the major attractions of the HSIM is its capability to handle motion segmentation ... -
A Kalman-filtering derivation of simultaneous input and state estimation
(Journal article; Peer reviewed, 2019)Simultaneous input and state estimation algorithms are studied as particular limits of Kalman filtering problems. This admits interpretation of the algorithm properties and critical analysis of their claims to being partly ...
