Improve auditing and privacy of electronic health records by using blockchain technology
(Master thesis, 2019-06-29)An ever-increasing amount of sensitive patient data is shared between healthcare institutions. The data is strictly personal and the consequences of unintentional disclosure are severe. Recordkeeping systems embedded in ... -
Improved bounds on W−W′ mixing with ATLAS resonant WZ production data at the LHC at √s=13 TeV
(Peer reviewed; Journal article, 2019)New charged vector bosons W ′ decaying into gauge boson pairs W Z are predicted in many scenarios of new physics, including models with an extended gauge sector (EGM). Due to the large variety of models (other unification ... -
Improved Combinatorial Bounds and Enumerators for the Connected Vertex Cover and Independent Feedback Vertex Set Problems
(Master thesis, 2018-06-20)In this thesis we shall study both the maximum number of minimal connected vertex covers and the maximum number of minimal independent feedback vertex sets in graphs. A subset S of the vertices of a graph G is a vertex ... -
Improved constraints on the mixing and mass of Z ′ bosons from resonant diboson searches at the LHC at √ s = 13 TeV and predictions for Run II
(Peer reviewed; Journal article, 2018)New neutral vector bosons Z ′ decaying to charged gauge boson pairs W + W − are predicted in many scenarios of new physics, including models with an extended gauge sector such as E 6 , left-right symmetric Z ′ LRS and the ... -
Improved density measurements of mesopelagic fish and the presence of physonect siphonophores in sound scattering layers, measured with multifrequency acoustics and a stereo camera mounted on a lowered probe
(Master thesis, 2018-12-11)The mesopelagic layer is a massive layer of biomass which stretches from 200-1000 meters depth in almost all locations of the world oceans. These layers are inhabited by many groups of animals, from small zooplankton to ... -
An Improved Estimate of the Coupled Arctic Energy Budget
(Peer reviewed; Journal article, 2019)This study combines state-of-the-art reanalyses such as the fifth-generation European Re-Analysis (ERA5) and the Ocean Reanalysis System 5 (ORAS5) with novel observational products to present an updated estimate of the ... -
Improved long-span bridge modeling using data-driven identification of vehicle-induced vibrations
(Journal article; Peer reviewed, 2020)The paper introduces a procedure to automatically identify key vehicle characteristics from vibrations data collected on a suspension bridge. The primary goal is to apply a model of the dynamic displacement response of a ... -
Improved multivariable algorithms for estimating oceanic particulate organic carbon concentration from optical backscattering and chlorophyll-a measurements
(Journal article; Peer reviewed, 2024-01-08)The capability to estimate the oceanic particulate organic carbon concentration (POC) from optical measurements is crucial for assessing the dynamics of this carbon reservoir and the capacity of the biological pump to ... -
Improved opacity expansion for medium-induced parton splitting
(Journal article; Peer reviewed, 2020-06-30)We present a new expansion scheme to compute the rate for parton splittings in dense and finite QCD media. In contrast to the standard opacity expansion, our expansion is performed around the harmonic oscillator whose ... -
Improved quantitative calibration of rock physics models
(Peer reviewed; Journal article, 2011-11)In reservoir characterization, rock-physics models provide the link between seismic observables (density, compressional and shear wavespeeds) and reservoir parameters such as porosity, lithology and fluid saturation. ... -
Improved seismic monitoring with OBS deployment in the Arctic: A pilot study from offshore western Svalbard
(Journal article; Peer reviewed, 2021)The mid‐ocean ridge system is the main source of earthquakes within the Arctic region. The earthquakes are recorded on the permanent land‐based stations in the region, although, smaller earthquakes remain undetected. In ... -
Improved stock estimation for Iceland scallops (Chlamys islandica) in the Svalbard area
(Master thesis, 2023-06-03)Iceland scallops (Chlamys islandica) were commercially harvested in the Svalbard fishery protection zone (FPZ) from 1986 to 1992, when the fishery ended due to overfishing. After approximately 30 years of prohibition, a ... -
An Improved Surface Boundary Condition for Large-Eddy Simulations Based on Monin–Obukhov Similarity Theory: Evaluation and Consequences for Grid Convergence in Neutral and Stable Conditions
(Peer reviewed; Journal article, 2020)Monin–Obukhov similarity theory is used in large-eddy simulation (LES) models as a surface boundary condition to predict the surface shear stress and scalar fluxes based on the gradients between the surface and the first ... -
