Ontology Design for Representation of mathematical Models
(Master thesis, 2015)In this study, ontologies intended for structuring information of physical-chemical-biological processes has been presented. The ontologies was implemented in a tool, called the "Ontology Editor", that facilitate for ... -
Optimisation of an Ammonia Synthesis Loop - Investigation of a Novel Approach for Optimisation of Integrated plants
(Master thesis, 2015)A Hysys model representing the steady state behaviour of a Haber-Bosch ammonia plant was developed based on a dynamic model and plant data from Norwegian fertiliser company Yara International ASA. The plant model was ... -
Optimization of a Reactor Network for Production of Butyl Butyrate by an Attainable Region Analysis
(Master thesis, 2017)Butyl butyrate is a promising supplement for jet fuel and diesel. It can be produced in a biotechnological process, by an esterification reaction between butanol and butyric acid. These intermediates can in turn be produced ... -
Optimization of Energy Storage in Buildings Based on Self-optimizing Control
(Master thesis, 2014)A steadily increasing fraction of Europe's electricity is generated by renewable and less reliable energy sources. It is therefore necessary to find smart ways to store excess energy until it is demanded. This could be ... -
Optimization of Operation and Remaining Lifetime of a Subsea System
(Master thesis, 2016)A model of a subsea system was developed and optimization for operation and remaining life time. For the modelling of the remaining life time the compressor efficiency was used as there is no statistical or physical model ... -
Parameter Estimation for Breakage and Coalescence Kernels in a Population Balance Framework
(Master thesis, 2018)In this work, a zero-dimensional model in the population balance framework has been developed for an oil-in-water emulsion in a batch continuously stirred tank reactor in order to calibrate four parameters to experimental ... -
Real Time Optimization and Nonlinear Model Predictive Control of a Gas Lifted Oil Network
(Master thesis, 2018)As oil reserves become scarcer, oil production and recovery must be enhanced. The gas lift is one of the techniques used to enhance oil production and recovery. It is usually used in reservoirs that suffer from insufficient ... -
Risk-based health-aware control of Åsgard subsea gas compression station
(Master thesis, 2018)Safe and efficient operation of subsea processing systems imposes strict requirements with respect to equipment design and reliability. This is to avoid accidental shutdowns, which can lead to expensive maintenance ... -
A Simplification Procedure for Distillation Tray Models
(Master thesis, 2018)The popularity of liquid separation by distillation in the industry has resulted in a wide range of distillation models. These models range from detailed flow models used in the design of trays and packings, to models ... -
Simulation and Analysis of RNA Polymerase Motion on the DNA
(Master thesis, 2018)RNA Polymerase is an enzyme that is frequently used to clone genetic material. However, backtracking seems to turn the process remarkably inefficient, because it leads to a lot of waste of raw material, making the cost of ... -
Simulation of Pilot Data with Aspen Plus
(Master thesis, 2015)Over the last few decades there has been an increasing interest in climate change and global warming. It is believed that one of the major causes of the enhanced greenhouse effect, that causes global warming, is anthropogenic ... -
Studying the effect of High pressure processing on Listeria monocytogenes in food and developing a model to suppress its resistance.
(Master thesis, 2014)High pressure processing (HPP) is a food treatment technique, developed to increase the shelf life of food by inhibition of microbial growth, at the same time as quality degradation is avoided. By using high pressure, the ... -
Superstructure Optimization of Early Stage Offshore Oil Field Development with Subsea Processing
(Master thesis, 2018)The oil and gas industry has been subject to a series of challenges during the last couple of decades, including increased water depths, step-out distances and harsher environmental and operational conditions. This has ... -
Symplectic integration of a one-dimensional Hamiltonian system of permanent magnets oscillating in a gravitational field. - A mechanical analogue to a thermodynamic system.
(Master thesis, 2014)The objective of this work was to analyze a mechanical analogue to a thermodynamic system. The main goal was to investigate the temperature distribution in a vertical system of oscillating magnets in a gravitational field ... -
Time Constant Considerations for a Simplified Charcoal Fired Furnace
(Master thesis, 2017)A mathematical model for a spherical control volume containing a combustion chamber buried in moist sand was derived based on the thermodynamic laws for heat transfer. The combustion chamber holds an iron core and a ...
