Faktorer for og effekter av frivillig atferdsendring ved bruk av myke mobilitetstiltak.
(Masteroppgave/UIS-TN-IØRP/2018;, Master thesis, 2018-06)Myke mobilitetstiltak for frivillig atferdsendring er blitt benyttet siden slutten av 90- tallet. Siden da er det gjort studier på slike tiltak i Australia, Storbritannia Europa, USA og Japan, der det kan forventes en ... -
Families of Proper Holomorphic Embeddings and Carleman-Type Theorem with parameters
(Peer reviewed; Journal article, 2023)We solve the problem of simultaneously embedding properly holomorphically into C2 a whole family of n-connected domains Omega_r in P1 such that none of the components of P1 \ Omega_r reduces to a point, by constructing a ... -
Fast and Reliable Byzantine Fault Tolerance
(Masteroppgave/UIS-TN-IDE/2016;, Master thesis, 2016-06)Byzantine faults, or arbitrary faults, are difficult to handle due to their unknown nature. They include software errors, hardware errors, and malicious behavior. There are several algorithms which handle Byzantine faults ... -
Fast and robust Bayesian inference using Gaussian processes with GPry
(Peer reviewed; Journal article, 2023)We present the GPry algorithm for fast Bayesian inference of general (non-Gaussian) posteriors with a moderate number of parameters. GPry does not need any pre-training, special hardware such as GPUs, and is intended as a ... -
Fast borestreng
(Masteroppgave/UIS-TN-IØRP/2013;, Master thesis, 2013)Fast borestreng er når en ikke kan rotere den, eller bevege strengen opp og ned. Flere mekanismer kan forårsake dette, blant annet formasjonsrelaterte problemer som for eksempel: ukonsoliderte formasjoner, mobile formasjoner, ... -
Fasthet-/ temperaturutvikling i betong
(Masteroppgave/UIS-TN-IKM/2014;, Master thesis, 2014-06-30)Arbeidsomfanget er å: • Undersøke effekten av pozzolaner på temperatur- og fasthetsutvikling • Gjennomgå årsak til spenningsdannelse i tverrsnittet og nær støpeskjøt • Utvikle et program for simulering av betongegenskaper ... -
Fastpriskontrakter i underentrepriser - Hvordan håndteres risiko ved økte mengder og prisstigning?
(Master thesis, 2023)Prisstigning på stål og trelast ga økte kostnader i byggeprosjekt A og B hos Alsaker Stål og Pretre. Byggebransjen har opplevd prisstigning på stål og trelast, som følge av uforutsette hendelser ved krigen i Ukraina og ... -
Fate and transport of contaminants in drill cuttings piles - Use of Klif's risk assessment guidelines for contaminated sediments to estimate leaching rates from oil-based drill cuttings piles.
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)The North Sea contains several oil-based drill cuttings piles which have accumulated on the seabed as a result of oil and gas production. An increased awareness of the contaminants within these piles has grown over the ... -
The fate of hydrocarbon leaks from plugged and abandoned wells by means of natural seepages
(Peer reviewed; Journal article, 2020-10)When a well reaches the end of its productive life, it is permanently plugged and abandoned. Even though new technology and verification methods are being evaluated, it is evident that operational, barrier material and ... -
Fate of persistent organic pollutants during anaerobic treatment and production of biopellets
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Treatment of municipal wastewater produces large quantities of sludge that represents a cost for the individual wastewater treatment plant. Proper sludge treatment enables reuse of sludge, possibly as fertilizers. Fertilizer ... -
Fatigue Analysis in Topside Pipe Systems Offshore
(Master thesis, 2021)Safety and reliability are terms generally associated with offshore oil and gas industry, particularly regarding piping where failure could potentially cause catastrophic outcomes. Hence, codes and standards have been ... -
Fatigue Analysis of Inter-Array Power Cables between Two Floating Offshore Wind Turbines Including a Simplified Method to Estimate Stress Factors
