A work process model for PdM evaluation in study phase: A case study
(Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-06)To a large degree, the fluctuation in oil prices has forced Oil & Gas (O&G) companies to invest in technologies that can aid lower costs and mitigate risk. This financial stability depends on a big extent on the performance ... -
Ab initio study: Investigating the adsorption behaviors of polarized greenhouse gas molecules on pillar[5]arenes
(Peer reviewed; Journal article, 2023)Supramolecular organic frameworks (SOFs) based on Pillar[5]arenes (P[5]A) have shown great potential in capturing and separating greenhouse gases. In this study, we investigate the adsorption behaviors of other environmentally ... -
Ab-initio QCD Calculations Impact the Inference of the Neutron-star-matter Equation of State
(Peer reviewed; Journal article, 2023)We demonstrate that ab-initio calculations in QCD at high densities offer significant and nontrivial information about the equation of state of matter in the cores of neutron stars, going beyond that which is obtainable ... -
Abandonment of obsolete wells and installations one the Norwegian continental shelf. A study into the magnitude of the technical and economic challenges.
(Masteroppgave/UIS-TN-IØRP/2014;, Master thesis, 2014-06-16)An increasing number of offshore installations on the Norwegian continental shelf (NSC) are passed their peak production, they require more and more maintenance and/or investments, and are rapidly approaching their end of ... -
Acceptance of wind power development and exposure – Not-in-anybody’s-backyard
(Peer reviewed; Journal article, 2020)Despite a large stated-preference (SP) literature on wind power externalities, few SP studies employ a case-control approach to examine whether people’s acceptance of new wind power developments and renewable energy ... -
Accessibility of bus transport in Nord-Jæren
(Master thesis, 2022)In line with aims of making the transport sector more sustainable, accessible bus service is essential. Nord-Jæren is an exciting geographical area concerning this because of heavy investments made here on bus rapid transit ... -
Accountability Requirements for the Cloud
(Chapter, 2017)In order to be responsible stewards of other people’s data, cloud providers must be accountable for their data handling practices. The potential long provider chains in cloud computing introduces additional accountability ... -
Accountability Requirements in the Cloud Provider Chain
(Journal article; Peer reviewed, 2018-04)In order to be responsible stewards of other people’s data, cloud providers must be accountable for their data handling practices. The potential long provider chains in cloud computing introduce additional accountability ... -
Accounting for Model Error in Probabilistic History Matching to Improve Uncertainty Quantification
(Master thesis, 2022)Model Error in probabilistic history matching is an important topic to study, but calculating the model error is a challenge since the truth is uncertain. In this thesis, sources of model error will be discussed briefly; ... -
Accuracy of Condensate to gas ratio (CGR) based on fluid sampling analyses.
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06-15)ABSTRACT Accuracy of condensate to the gas ratio (CGR) is one of the most significant issues in the petroleum industry. In this study, Ormen Lange field was the case study for checking the accuracy of CGR based on ... -
Accurate predictions of the Ultimate Limit State Wave Loads on Bottom Fixed Wind Turbine
(Master thesis, 2022)In this project the breaking wave loads on a bottom fixed monopile has been determined with the use of the Pressure Impulse Model. The pressure impulse model is the integral of pressure dependent by time during a short ... -
Accurate Predictions of Ultimate Limit State Wave Loads on Bottom Fixed Wind Turbine
(Master thesis, 2021)The breaking wave loads on a bottom fixed monopile foundation has been determined in this project with the aid of a Pressure Impulse Method. The pressure impulse method is the integration of pressure bounded by time within ... -
Acoustic Emission Testing for offshore jacket structures
(Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-06-14)Structural health monitoring (SHM) is a critical tool to assess the structural integrity of many applications. Early detection for damage can extend the lifetime for structures through replacing damaged parts and can lower ... -
Acquisition, Processing and Interpretation of Ground Penetrating Radar (GPR) Data in Aidonia, Greece
(Masteroppgave/UIS-TN-IER/2020;, Master thesis, 2020)The Mycenaean Cemetery of Aidonia, Greece, is located about 10 km west of the town of New Nemea on the Peloponnese peninsula. In this cemetery, a number of chamber tombs dating from 1600-1100 B.C. was discovered in the ... -
Acropolis: aggregated client request ordering by Paxos
(Masteroppgave/UIS-TN-IDE/2013;, Master thesis, 2013)The consensus problem is one of the most central problems in distributed system. Paxos, an algorithm that solves this problem, can be used to im- plement replicated state machines (RSMs). By running Paxos for each of the ... -
Active Noise Control in the Offshore Industry
(Masteroppgave/UIS-TN-IDE/2020;, Master thesis, 2020-06-29)Hearing damage among offshore workers has been a problem for many years, and it remains one of the most common disorders in this group. A proposal to use active noise control to improve the noise conditions has thus been ... -
