System for Workflow Design and Execution on Data Shared Between Untrusting Organizations for Analytics
(Master thesis, 2022)Performance of complex analytics \& AI algorithms typically involves large amounts of data. The data may originate from multiple sources and is typically compiled and moved to a central location before it can be consumed ... -
System of Comprehensive Energy-Efficient Utilization of Associated Petroleum Gas with Reduced Carbon Footprint in the Field Conditions
(Peer reviewed; Journal article, 2020)This paper considers the issue of associated petroleum gas utilization during hydrocarbon production in remote petroleum fields. Due to the depletion of conventional oil and gas deposits around the globe, production shifts ... -
Systematic atomic force microscopy and constraints for the determination of wettability and EOR research
(Masteroppgave/UIS-TN-IER/2020;, Master thesis, 2020-07)A highly attractive strategy within the hydrocarbon industry is improving the percentage of recovery from the reservoirs, called Improved Oil Recovery/Enhanced Oil Recovery (IOR/EOR). The Atomic Force Microscope (AFM) is ... -
A Systematic Overview of Blockchain Research
(Peer reviewed; Journal article, 2021)Blockchain has been receiving growing attention from both academia and practices. This paper aims to investigate the research status of blockchain-related studies and to analyze the development and evolution of this latest ... -
A systematic review of associations between common SNCA variants and clinical heterogeneity in Parkinson's disease
(Peer reviewed; Journal article, 2021-07)There is great heterogeneity in both the clinical presentation and rate of disease progression among patients with Parkinson’s disease (PD). This can pose prognostic difficulties in a clinical setting, and a greater ... -
A Systematic Review of Fairness, Accountability, Transparency and Ethics in Information Retrieval
(Peer reviewed; Journal article, 2023)We live in an information society that strongly relies on information retrieval systems, such as search engines and conversational assistants. Consequently, the trustworthiness of these systems is of critical importance, ... -
Systematic Specific Surface Area Analyses on Rocks to Implement as a Necessary, Quick, and Informative Method to Understand Geo-Mechanical Parameter in IOR Experiments
(Masteroppgave/UIS-TN-IER/2018;, Master thesis, 2018-07-11)Specific surface area (SSA) of a particle can make a major impact in understanding reservoir rock characteristics where it may indicate the possibility of fluid content. The purpose of this study is to measure and understand ... -
Systempåitelighet av et voksbehandlingssystem: Bruk av Markovkjeder i en innledende pålitelighetsanalyse av ny subsea teknologi
(Master thesis, 2021)One challenge related to subsea oil operations is wax deposition on the oil pipeline. The problem arises when hot crude oil comes in contact with a cold pipeline. The paraffin wax, present in hot crude oil, crystallizes ... -
A systems biology approach to cellular homeostasis, volume changes and regulation of metabolism
(PhD thesis UiS;509, Doctoral thesis, 2020-04)Cells need to respond to a vast range of different disturbances and changes over small and large time scales. This can be disturbances in the form of molecules used to fight infectious states, changes in growth patterns, ... -
Systems dynamic model of wear evolution for sheaves used in oil and gas hoisting operations
