Dynamic incorporation of nonlinearity into MILP formulation for short-term hydro scheduling
(Journal article; Peer reviewed, 2019)Optimization tools are widely used for solving the short-term hydro scheduling (STHS) problem in a cascaded hydro system. In a mixed integer linear programming (MILP)-based formulation, the nonlinear and non-convex hydropower ... -
Dynamic indexes vs. static hierarchies for substring search
(Master thesis, 2005)This report explores the problem of substring search in a dynamic document set. The operations supported are document inclusion, document removal and queries. This is a well explored field for word indexes, but not for ... -
Dynamic learning spaces—dynamic pedagogy. Students’ voices from a master’s program focusing on student active learning in a cross-institution two-campus organization
(Peer reviewed; Journal article, 2023)These past few years have shown the importance of successfully designing cross-campus and multi-campus hybrid and fully digital learning environments to sustain and guarantee continuity in learners’ higher education - an ... -
A dynamic lithosphere–asthenosphere boundary near the equatorial Mid-Atlantic Ridge
(Peer reviewed; Journal article, 2021)In plate tectonic theory a weak asthenosphere is required to facilitate the motions of the rigid plates. Partial melt could weaken the mantle, in turn impacting convection, but to date the existence of persistent melt has ... -
Dynamic Management of Software Components in a Ubiquitous Collaborative Environment
(Master thesis, 2010)The key motivation of this thesis is to find innovative solutions for facilitating the deployment of ubiquitous systems, with the purpose of making technology supported collaboration an easier task. Users, being in a ... -
Dynamic model of a tendon-actuated snake robot using the Newton-Euler formulation
(Chapter, 2023)Dynamic models are necessary when dealing with robotic applications where requirements of dexterity, manipulability, payload and compliance have to be satisfied at the same time. This work considers a particular design of ... -
Dynamic Model of Mobile Inspection Robot for Industrial Robot Applications

A dynamic model of two-phase flow for simulating gas kick and facilitating model-based control in drilling operations
(Peer reviewed; Journal article, 2021)A low-order two-phase dynamic flow model for drilling operations with gas kick is developed. The purpose is to enable fast and robust simulation of the behavior and propagation of influx gas in the bore hole, and the effects ... -
Dynamic modeling and optimization of sustainable algal production with uncertainty using multivariate Gaussian processes
(Journal article; Peer reviewed, 2018)Dynamic modeling is an important tool to gain better understanding of complex bioprocesses and to determine optimal operating conditions for process control. Currently, two modeling methodologies have been applied to ... -
Dynamic Modeling and Simulation of Robot Manipulators: The Newton-Euler Formulation
(Master thesis, 2011)Dynamic modeling means deriving equations that explicitly describes the relationship between force and motion in a system. To be able to control a robot manipulator as required by its operation, it is important to consider ... -
Dynamic Modeling of a Wind Turbine System
(Master thesis, 2011)The objective of this paper is to derive a simple dynamic model of a wind turbine system, with focus on mechanical conditions. The investigated system is assumed to be a 10 MW reference wind turbine, with variable speed ... -
Dynamic Modelling and Control Design of Pre-combustion Power Cycles
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:227, Doctoral thesis, 2012)Pre-combustion capture is an important CCS technology. Pre-combustion capture of CO2 incurs less of an energy penalty than current post combustion technologies. For this type of reforming to be competitive for power ... -
