Optimizing Groundwater Level Prediction: Improving Time-Series Reconstruction and Donor Site Selection Strategies
(Master thesis, 2023)Tidsserieprediksjon for grunnvannsnivå spiller en avgjørende rolle i vannressursforvaltningen, spesielt når data er begrenset. Den nåværende datadrevne estimeringen på uovervåkede steder ved bruk av komparativ regional ... -
Optimizing Hybrid Ventilation Control Strategies Toward Zero-Cooling Energy Building
(Journal article; Peer reviewed, 2019)Optimal ventilation strategies are fundamental to achieve net/nearly-zero energy buildings. In this study, three hybrid ventilation control strategies are proposed to minimize the cooling need in an open-plan office building, ... -
Optimizing Pico Hydropower: Enhancing Overshot Waterwheel Performance for Off-Grid Electrification
(Master thesis, 2023)Denne avhandlingen utforsker konseptet med en pico vannkraftenhet som bruker et overhengende vannhjul med mulighet for variabel rotasjonshastighet, med mål om å tilby en egnet energikilde for samfunn uten pålitelig tilgang ... -
Optimizing Road Gradients Regarding Earthwork Cost, Fuel Cost, and Tank-to-Wheel Emissions
(Journal article, 2020)Emissions reduction has emerged as one of the principal targets in the planning and designing of road alignment today, and intelligent design methods can help optimize road alignment as a response toward more sustainable ... -
Optimizing surge tank layout for highly flexible hydropower
(Journal article; Peer reviewed, 2018)This article considers high-head hydropower schemes and pumped storage schemes that usually are considered as flexible power plants. Surge tanks are the key structural element in the hydropower scheme for flexible operation ... -
Optimizing the Micro-Tasking Workflow and Exploring its Usage Potential Within Geospatial Data
(Master thesis, 2017)Micro-tasking is the process of dividing a large task into smaller parts, making the task easier to distribute and lowering its complexity. This process is used commercially to solve tasks such as labeling images, translating ... -
Organisering av prosjektering i totalentrepriser
(Master thesis, 2011)Prosjektering er en av de tidlige fasene i bygge- og anleggsprosjekter hvor man legger mange av de viktige føringene, som i stor grad påvirker utfallet av et prosjekt. Prosjektering omtales av mange som den mest utfordrende ... -
Organisering og ledelse av prosjekteringsprosessen - Med fokus på tidligfasen i byggeprosjekter
(Master thesis, 2018)Tidligere forskning viser en enighet om at manglende planlegging av prosjekteringsprosessen skaper problemer som dårlig detaljeringsgrad, feil, mangler og forsinkelser. Som Eiken (2013) sier: Næringen er samstemt i at det ... -
Organosilane and lignosulfonate as innovative stabilization techniques for crushed rocks used in road unbound layers
