Dynamic Real-Time Optimisation of an Amine-Based Post-Combustion CO2 Capture Facility using Single-Level Nonlinear Model Predictive Control
(Master thesis, 2018)A complete model of a CO2 capture facility has been optimised with the aid of Dynamic Real-Time Optimisation (DRTO) utilising single-level, Nonlinear Model Predictive Control to merge regulatory and economic objectives. ... -
Dynamic relations between humans and environment in the earliest settlement phase of Norway (9500-8000 cal BC)
(Doctoral theses at NTNU;2016:287, Doctoral thesis, 2016)Summary of the thesis For more than 11,000 years ago, human groups entered and utilized territories that today belong to Norway. The colonization process took place after the last Ice Age, within a period of 1500 years ... -
Dynamic relationship between board gender diversity and renewable energy
(Chapter, 2021)This chapter investigates whether board gender diversity affects firms’ renewable energy use. Employing a sample of U.S. environmentally responsible firms, I find support for the hypothesis that board gender diversity ... -
Dynamic relationship between multiple START assessments and violent incidents over time: a prospective cohort study
(Journal article; Peer reviewed, 2014)Background: Dynamic risk factors need to be assessed repeatedly over time rather than at a single time point to examine the relationship with violence. This predictive validity study sought to examine the degree of ... -
Dynamic renormalization group of interfaces in scalar active matter
(Master thesis, 2022)Biologiske systemer er ofte bygget opp av partikler som er kapable til å transformere kjemisk energy som er lagret i systemet til arbeid eller felles bevegelse. Slike systemer kalles aktive systemer og kan eksemplifiseres ... -
Dynamic Resource Allocation with Maritime Application (DRAMA): Final Report
(Research report, 2014)An important challenge within the offshore industry and sea traffic preparedness is how to plan and optimise the positioning of a fleet of vessels in a dynamic, everchanging environment such that operating costs and risks ... -
