Optimization in CT: Evaluation of dose saving potential in a thorax-abdomen/pelvis protocol using iterative reconstruction techniques
(Master thesis, 2013)The use of computed tomography (CT) has increased dramatically during the last two decades and contributes today to 80% of the estimated population dose caused by radiological examinations. Recent publications have shown ... -
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 an Absorption-Based Biogas Upgrading and Liquefaction Process
(Journal article; Peer reviewed, 2019)The present work proposes a methodology for optimization of a liquefied biomethane (LBM) production plant. The LBM production plant comprises amine-based absorption upgrading followed by a single expander refrigeration ... -
Optimization of chemical composition of novel manganite oxides for oxygen permeable membranes
(Master thesis, 2015)Every year, millions of tons of high purity oxygen are produced mainly by cryogenic distillation. Since this process is energetically demanding, there is a need for more energy efficient technologies, and the use of oxygen ... -
Optimization of Co-Ni-Mg-Al mixed-oxides CO2 methanation catalysts with solution combustion synthesis: On the importance of Co incorporation and basicity
(Peer reviewed; Journal article, 2023)Hydrogenation of CO2 to methane is a promising prospect for the utilization of carbon dioxide. Ni-Mg-Al mixed oxides have been reported as a catalyst for this process. Their promotion with cobalt allows to improve Ni ... -
Optimization of Deacetylation Process for Regenerated Cellulose Hollow Fiber Membranes
(Journal article; Peer reviewed, 2017)Cellulose acetate (CA) hollow fibers were spun from a CA+ Polyvinylpyrrolidone (PVP)/N-methyl-2-pyrrolidone (NMP)/H2O dope solution and regenerated by deacetylation. The complete deacetylation time of 0.5 h was found at a ... -
Optimization of diffusion weighted-MRI: a study of T2 and ADC in healthy fibroglandular breast tissue
(Master thesis, 2019)Diffusjonsvektet magnetisk resonansavbildning er blitt stadig mer populært i deteksjon, gradering og evaluering av respons på behandling i brystkreft. Den tilsynelatende diffusjonskonstanten (ADC) reduseres i stor grad i ... -
