Combined positron emission tomography and computed tomography to visualize and quantify fluid flow in sedimentary rocks
(Peer reviewed; Journal article, 2015-09-22)Here we show for the first time the combined positron emission tomography (PET) and computed tomography (CT) imaging of flow processes within porous rocks to quantify the development in local fluid saturations. The coupling ... -
Combined RBE and OER optimization in proton therapy with FLUKA based on EF5-PET
(Journal article; Peer reviewed, 2023)Introduction Tumor hypoxia is associated with poor treatment outcome. Hypoxic regions are more radioresistant than well-oxygenated regions, as quantified by the oxygen enhancement ratio (OER). In optimization of proton ... -
Combined thickness and permittivity measurement of layers using an open-ended coaxial probe
(Master thesis, 2018-06-11)The purpose of this thesis is to develop a method for estimating both the thickness and permittivity of layers simultaneously utilizing an open-ended coaxial probe. One possible application of this method is the detection ... -

Combustion of Gas in Closed, Interconnected Vessels: Pressure Piling
(Master thesis, 2004)This thesis is the documentation of a study of gas explosions in closed, interconnected vessels. Explosions within such vessels is strongly affected by the characteristics of the geometry, and can, under given conditions, ... -
A Comparative Study of Radiation Environment and Secondary Dose Production in a Particle Therapy Treatment Room Applying Proton, Helium and Carbon Ion Beams
(Master thesis, 2015-11-20)A treatment room used for radiotherapy is generally heavily shielded and has to fulfil and abide to strict rules and regulations in order to ensure the safety and health of hospital personnel and the general public that ... -
A Comparative Study on the Influence of Obstacles on Flame Propagation in Dust and Gas Mixtures. An experimental study of confined and vented scenarios in a 3.6 meter flame acceleration tube
(Master thesis, 2012-06-01)This thesis describes an experimental investigation of flame propagation in a 3.6-meter Flame Acceleration Tube (FAT) with square 0.27m x0.27m cross section. The experiments in the FAT took place at the premises of GexCon ... -
Comparative study on the uniform energy deposition achievable via optimized plasmonic nanoresonator distributions
(Journal article; Peer reviewed, 2022)Plasmonic nanoresonators of core–shell composition and nanorod shape were optimized to tune their absorption cross-section maximum to the central wavelength of a short laser pulse. The number density distribution of randomly ... -
Comparing the effects of solar-related and terrestrial drivers on the northern polar vortex
(Journal article; Peer reviewed, 2020)Northern polar vortex experiences significant variability during Arctic winter. Solar activity contributes to this variability via solar irradiance and energetic particle precipitation. Recent studies have found that ... -
Comparing Three Approaches to the Inducing Source Setting for the Ground Electromagnetic Field Modeling due to Space Weather Events
(Journal article; Peer reviewed, 2020)Ground-based technological systems, such as power grids, can be affected by geomagnetically induced currents (GIC) during geomagnetic storms and magnetospheric substorms. This motivates the necessity to numerically simulate ... -
Comparison of burning velocity differences in a numerical explosion simulator
(Master thesis, 2014-06-02)A verification study of the two flame models in the numerical explosion simulation tool FLACS has been conducted. The beta flame model, and the SIF flame model has been tested in a 1D-channel at different time step sizes. ... -
Comparison of fragmentation functions for jets dominated by light quarks and gluons from pp and Pb+Pb collisions in ATLAS
