Online data compression in the ALICE O\(^2\) facility
(Peer reviewed; Journal article, 2017)The ALICE Collaboration and the ALICE O2 project have carried out detailed studies for a new online computing facility planned to be deployed for Run 3 of the Large Hadron Collider (LHC) at CERN. Some of the main aspects ... -
Onset of smoldering and transition to flaming fire
(Doctoral thesis, 2013-06-28)Aim: The aim of this work has been to investigate the effects of density, heat flux and boundary conditions on smoldering. Two focus areas were chosen: the onset of smoldering and the transition from smoldering to flaming ... -
Onset of Spontaneous Imbibition
(Master thesis, 2017-06-22)The spontaneous imbibition process in porous media is an important recovery mechanism and is governed by capillary forces that arise when two immiscible fluids are present in the pore space. This thesis presents new ... -
Open heavy-flavour production and elliptic flow in p-Pb collisions at the LHC with ALICE
(Peer reviewed; Journal article, 2019)Measurements of open heavy flavour production in p–A collisions allow the investigation of Cold Nuclear Matter effects. In addition, they are an important tool for a complementary investigation of the long-range correlations ... -
Operation and performance of the ATLAS Tile Calorimeter in Run 1
(Peer reviewed; Journal article, 2018-11-30)The Tile Calorimeter is the hadron calorimeter covering the central region of the ATLAS experiment at the Large Hadron Collider. Approximately 10,000 photomultipliers collect light from scintillating tiles acting as the ... -
Optical emissions associated with narrow bipolar events from thunderstorm clouds penetrating into the stratosphere
(Journal article; Peer reviewed, 2021)Narrow bipolar events (NBEs) are signatures in radio signals from thunderstorms observed by ground-based receivers. NBEs may occur at the onset of lightning, but the discharge process is not well understood. Here, we present ... -
Optical Insight Into Riverine Influences on Dissolved and Particulate Organic Carbon in a Coastal Arctic Lagoon System
(Journal article; Peer reviewed, 2023)Arctic coastal margins receive organic material input from rivers, melted sea ice, and coastal erosion, phenomena that are all undergoing changes related to global climate. The optical properties of coastal Arctic waters ... -
Optical spectroscopy for tissue diagnostics and treatment control
(Doctoral thesis, 2006-06-28)Biomedical Optics as an interdisciplinary field of science has been developed during many years and is experiencing tremendous growth, to cover a wide range of optical techniques and methods, utilized for medical therapeutic ... -
Optical velocity meter based on Ramsey oscillations in a double-grating setup
(Peer reviewed; Journal article, 2014-04)We propose a method for measuring velocities of atoms or molecules in a gas phase based on time-resolved laser experiments. Two intensity gratings of electromagnetic field with variable time delay τ are created by interfering ... -
Optimisation of large-radius jet reconstruction for the ATLAS detector in 13 TeV proton–proton collisions
(Journal article; Peer reviewed, 2021)Jet substructure has provided new opportunities for searches and measurements at the LHC, and has seen continuous development since the optimization of the large-radius jet definition used by ATLAS was performed during Run ... -
Optimization of proton therapy plans with respect to biological and physical dose distributions
(Master thesis, 2018-06-16)Introduction: Proton therapy is a radiation treatment method growing around the world. This is mainly due to the protons ability to deposit dose more conformal compared to conventional photon therapy. Protons also differ ... -
Optimization, evaluation and application of EEP measurements in the presence of contaminating protons
(Master thesis, 2017)It is well known that energetic particles can penetrate deep into the atmosphere and initiate a chain of chemical reactions, ultimately leading to enhanced production rates of HOx and NOx molecules and the depletion of ... -
Optimized mesoscale growth of microalgae: A modelling approach
(Master thesis, 2017-11-20)Photosynthesis is a process that uses water, carbon dioxide and light to create sugar and oxygen. Sugar and oxygen is then used by the cell for maintenance and growth purposes through cellular respiration. We would then ... -
Optimizing hydroxyl airglow retrievals from long-slit astronomical spectroscopic observations
(Peer reviewed; Journal article, 2017-08-25)Astronomical spectroscopic observations from ground-based telescopes contain background emission lines from the terrestrial atmosphere's airglow. In the near infrared, this background is composed mainly of emission from ... -
