Invariant characterization of Szekeres models with positive cosmological constant
(Peer reviewed; Journal article, 2022-07)We present an invariant characterization of black holes in the Szekeres spacetime with positive cosmological constant. In the formation of the black holes, we locate geometric horizons, and show that they coincide with the ... -
An Invariant Characterization of the Levi-Civita Spacetimes
(Peer reviewed; Journal article, 2021-08)In the years 1917–1919 Tullio Levi-Civita published a number of papers presenting new solutions to Einstein’s equations. This work, while partially translated, remains largely inaccessible to English speaking researchers. ... -
Invasion of CaCO3 particles and polymers into porous formations in presence of fibres
(Peer reviewed; Journal article, 2022)Formation damage can occur through migration of drilling fluid particles and polymers into porous formations. A methodology for assessing formation damage was applied to measure invasion of CaCO3 and polymers into porous ... -
Invasive cancerous area detection in non-muscle invasive bladder cancer whole slide images
(Chapter, 2022)Bladder cancer patients’ stratification into risk groups relies on grade, stage and clinical factors. For non-muscle invasive bladder cancer, T1 tumours that invade the subepithelial tissue are high-risk lesions with a ... -
Inverse magnetic catalysis and regularization in the quark-meson model
(Journal article; Peer reviewed, 2015-02)Motivated by recent work on inverse magnetic catalysis at finite temperature, we study the quark-meson model using both dimensional regularization and a sharp cutoff. We calculate the critical temperature for the chiral ... -
INVERSION methods to determine the in-situ stresses
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-12)The challenges pose by the uncertainty in the in-situ stress measurement in the petroleum and mining industries are enormous. A handy computer tool to estimate the magnitude and direction of the horizontal in-situ stresses ... -
Investeringsanalyse av en Unmanned Surface Vessel til subseaoperasjoner
(Master thesis, 2021)I 2015 signerte 196 parter Parisavtalen, en juridisk bindende internasjonal traktat om klimaendringer. Formålet med denne pakten er å holde den globale oppvarmingen godt under 2 ° C, og helst til 1,5 ° C, med nasjoner som ... -

Investeringsbeslutning i olje- og gassindustri under usikkerhet - metodeforslag for usikkerhetshåndtering i investeringsprosjekter for TOTAL : en utredning innenfor petroleumsøkonomi
(Masteroppgave/UIS-TN-IØRP/2012;, Master thesis, 2012)Med utgangspunk i stadig større usikkerhet, ustabilitet og konstante forandringer i petroleumsindustrien er det i denne oppgavens utredning tatt for seg og redegjort for de viktigste elementene ved en investeringsbeslutning ... -
Investigated Miscible CO2 Flooding for Enhancing Oil Recovery in Wettability Altered Chalk and Sandstone Rocks
(PhD thesis UiS;162, Doctoral thesis, 2012-05-29)The thesis addresses oil recovery by miscible CO2 flooding from modified sandstone and chalk rocks. Calcite mineral surface is modified with stearic acid (SA) and asphaltene, and the silicate mineral surfaces are modified ... -
Investigating Biochar as potential remediator of Ciprofloxacin in hospital wastewater
(Bachelor thesis, 2023)This thesis investigates the potential for the cheap, easy-to-produce adsorbent Biochar for use as a remediator of the antibiotic Ciprofloxacin, which is known to pollute bodies of water especially downstream from hospitals ... -
Investigating Effects of Fused-Deposition Modeling (FDM) Processing Parameters on Flexural Properties of ULTEM 9085 using Designed Experiment
(Journal article; Peer reviewed, 2018-03)Fused-deposition modeling (FDM), one of the additive manufacturing (AM) technologies, is an advanced digital manufacturing technique that produces parts by heating, extruding and depositing filaments of thermoplastic ... -
Investigating eor for ss by low salinity water
(Masteroppgave/UIS-TN-IØRP/2013;, Master thesis, 2013)Water flooding has for a very long time been used to improve oil recovery, in the recent years researchers have become aware of the effects from controlling the salinity and composition of the injected water. Low salinity ... -
Investigating H-Titanate and MOFs for the recovery of Lithium from the spent battery waste (Black Mass)
(Master thesis, 2022)Lithium ion batteries (LIBs) are widely used for electric vehicles and other portable electronic devices. Basically, lithium-ion batteries contain valuable metals such as Fe, C, Al, Cu, Li, Co, and, Ni. Cobalt with 5– 20 ... -
Investigating how partial aggregation impacts K-means
(Masteroppgave/UIS-TN-IDE/2012;, Master thesis, 2012)K-means is the most commonly known partitioning algorithm used for data clustering. It was originally designed to run on a single processor. Therefore, this created a limitation on dealing with large amounts of data ... -
Investigating phosphate release from EBPR sludge and associated possibility of controlled struvite precipitation at SNJ wastewater treatment plant
(Masteroppgave/UIS-TN-IKBM/2018;, Master thesis, 2018-06)The main treatment stage at SNJ Wastewater Treatment Plant was recently upgraded from chemical treatment to mechanical-biological treatment with Enhanced Biological Phosphorous Removal (EBPR). The implementation of EBPR ... -
