The Evolution of Fixed-Supply and Variable-Supply Currencies
(Peer reviewed; Journal article, 2022-04)Competition is analyzed between a fixed-supply currency (e.g. Bitcoin) and a variable-supply currency (e.g. a fiat currency). Two kinds of players support the currencies differently and choose their volume fractions of ... -
Evolution of porosity and permeability in chalk as an effect of variations in non-carbonate minerals and testing temperature
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06)Pressure decline during oil recovery from chalk reservoirs exhibit increase in effective stress and this in turn leads to reservoir compaction causing seabed subsidence. Although, there is positive impact of compaction on ... -
Evolution of Scientific Management Towards Performance Measurement and Managing Systems for Sustainable Performance in Industrial Assets : Philosophical Point of View
(Journal article, 2009-01)Even though remarkable progress has been made over recent years in the design of performance measurement frameworks and systems, many companies are still primarily relying on traditional financial performance measures. ... -
Evolution of the southern Llanos basin
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)The Llanos basin, located in the eastern region of Colombia, South America, is a foreland basin between the Eastern Cordillera (Colombian Andes) and the Guyana Precambrian shield. This Andean foreland basin is the latest ... -
Evolution of wetting index over time in mixed wet Kansas chalk using triaxial cells
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)Magnesium chloride effects have been widely studied in short and long-term core flooding experiments through outcrop chalk cores. Three main changes are induced by this reactive brine: ion exchange, dissolution of calcite ... -
Evolutionary analysis of cellular reduction and anaerobicity in the hyper-prevalent gut microbe Blastocystis
(Peer reviewed; Journal article, 2023)Blastocystis is the most prevalent microbial eukaryote in the human and animal gut, yet its role as commensal or parasite is still under debate. Blastocystis has clearly undergone evolutionary adaptation to the gut environment ... -
Evolutionary Maintenance of the PTS2 Protein Import Pathway in the Stramenopile Alga Nannochloropsis
(Peer reviewed; Journal article, 2020)The stramenopile alga Nannochloropsis evolved by secondary endosymbiosis of a red alga by a heterotrophic host cell and emerged as a promising organism for biotechnological applications, such as the production of polyunsaturated ... -
Evolving Deep Neural Networks for Continuous Learning: Addressing Challenges and Adapting to Changing Data Conditions without Catastrophic Forgetting
(Master thesis, 2023)Continuous learning plays a crucial role in advancing the field of machine learning by addressing the challenges posed by evolving data and complex learning tasks. This thesis presents a novel approach to address the ... -
Ex-Post (Pseudo) Out-of-Sample Forecast Accuracy of Proposed Oil Price Models
(Masteroppgave/UIS-TN-ISØP/2020;, Master thesis, 2020-06-28)This thesis aims to test and compare some of the most frequently applied models in the forecasting literature, for their ability to produce accurate ex-post (pseudo) out of-sample forecasts of the crude oil price. These ... -
Exact Solutions of the Field Equations for Empty Space in the Nash Gravitational Theory
(Journal article; Peer reviewed, 2017-02)John Nash has proposed a new theory of gravity. We define a Nash-tensor equal to the curvature tensor appearing in the Nash field equations for empty space, and calculate its components for two cases: 1. A static, spherically ... -
Examination of Dynamic Stress and Conductivity in the Eldfisk Chalk Field
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-05-26)This thesis work has been conducted in cooperation with ConocoPhillips Norway and looks at the stress development in the Eldfisk chalk reservoir. High injection pressures due to the relatively low permeabilities of chalk ... -
Exceptional nonrelativistic effective field theories with enhanced symmetries
(Peer reviewed; Journal article, 2021)We initiate the classification of nonrelativistic effective field theories (EFTs) for Nambu-Goldstone (NG) bosons, possessing a set of redundant, coordinate-dependent symmetries. Similarly to the relativistic case, such ... -
Excessive Daytime Sleepiness and REM Sleep Behavior Disorders in Parkinson's Disease: A Narrative Review on Early Intervention With Implications to Neuroprotection
(Journal article; Peer reviewed, 2018-11)Sleep contributes to the consolidation of our memory and facilitates learning. Short term sleep deprivation temporarily reduces mnestic capacity, whereas long lasting sleep deprivation is associated with structural changes ... -
Excision of 5-hydroxymethyluracil in single-stranded DNA by hSMUG1 requires Ser26 and/or Glu35 and Pro240
(Master thesis, 2021)The integrity of the genetic material of all organisms is assaulted continuously by a multitude of endogenous and exogenous agents throughout its lifetime, where the DNA bases of the genetic code may be altered if not ... -

Expanding PIN system – Combined radial and axial locking system
(Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2020-07-15)In the side by side plate joints or flange joints, the standard practice is to have a bolted connection that provides the axial clamping load as well as, avoiding any radial or rotational movement. This can be problematic ... -
Expanding the Well Intervention Scope for an Effective P&A Operation
(Master thesis, 2017-06-14)Over 2500 wells on the Norwegian Continental Shelf (NCS) will at some point have to be permanently plugged and abandoned. As the drill rig rate contributes to 40-50% of the total plug and abandonment (P&A) cost, the potential ... -
