Tuning Effect on Near and Far Offset Stacks: Mapping the Thickness Beneath Seismic Resolution of a Shallow Thin Layer in Block 2/4.
(Master thesis, 2014)Analysis of high-amplitude anomalies (bright spots) are the most used basic method of identifying hydrocarbon accumulations in seismic signals. When this method is applied to thin-bedded strata, the result can be misleading. ... -
Tuning of transfer functions for analysis of wave–ship interactions
(Peer reviewed; Journal article, 2021)Transfer functions are often used together with a wave spectrum for analysis of wave–ship interactions, where one application addresses the prediction of wave-induced motions or other types of global responses. This paper ... -
Tuning of vessel parameters including sea state dependent roll damping
(Peer reviewed; Journal article, 2021)Online tuning of vessel models based on onboard measurement data can reduce the uncertainties of vessel motion prediction, and therefore potentially increase the safety and cost efficiency for marine operations. Among the ... -
Tuning the Casimir-Lifshitz force with gapped metals
(Peer reviewed; Journal article, 2023)The Casimir-Lifshitz interaction, a long-range force that arises between solids and molecules due to quantum fluctuations in electromagnetic fields, has been widely studied in solid-state physics. The degree of polarization ... -
Tuning the extent of porosity and composition of N-doped carbon materials by NaNO3 and its effect on electrochemical activity
(Journal article; Peer reviewed, 2018)A facile one-pot method using NaNO3 as etching agent in a molten salt medium is developed to tune the porous structure and composition of N-doped carbon materials derived from biomass at high temperatures. SEM and TEM ... -
Tunnel Contour Quality Index in a drill and blast tunnel: Definition, analysis and effects
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:197, Doctoral thesis, 2009)The drill and blast (D&B) method is applied in the excavation of a wide range of underground spaces, such as tunnels, rock caverns and mines. It has been progressing rapidly to reduce construction time and cost with the ... -
Tunnel Finnsnes - Ingeniørgeologiske vurderinger: Spesiell fokus på mixed-face tunnel
(Master thesis, 2010)Dette prosjektet er skrevet som en master-/ diplomoppgave ved NTNU i Trondheim, som den avsluttende delen av forfatterens masterstudie. Masteroppgaven omhandler ingeniørgeologiske forhold ved en tunnel planlagt på Finnsnes, ... -
Tunnel System Design for the Kuli Pumped Hydro Storage Project
(Master thesis, 2020)From the beginning of 20th century, huge tensions rising about global warming and environmental pollution from utilizing fossil fuels enormously. Implementing pump hydro storage profoundly can reduce the extensive use of ... -
Tunnel under Hardangervidda: Vurdering av drivemetode og traséplassering
(Master thesis, 2013)Hensikten med denne masteroppgaven var å belyse sentrale aspekter ved etablering av en tunnel under Hardangervidda. For å gjøre dette har denne rapporten gått gjennom, utarbeidet og fremstilt et helhetlig grunnlag nødvendig ... -
Tunnelbyggetid 2021 - testet i et komplekst tunnelprosjekt
(Master thesis, 2023)I anleggsbransjen har det oppstått usikkerhet, konflikter og til dels tvister omkring byggetiden til samferdselstunneler de siste tiårene. For å redusere uenighetene har entreprenørforeningen for Bygg og Anlegg, sammen med ... -
Tunnelbyggetid for vann- og frostsikring
(Master thesis, 2022)Byggetid for tunneler har i det siste tiåret ført til økende grad av uenighet og tvister som til sammen utgjør en betydelig verdi. Et samarbeidsforum bestående av ulike byggherrer, entreprenører, NTNU og Entreprenørforeningen ... -
Tunnelbyggetid ved rystelsesbegrensninger
(Bachelor thesis, 2021)Ved bygging av en tunnel må det noen ganger tas hensyn til eksisterende konstruksjoner som gjør at metoden for tunneldrivingen må endres. Gjennombrytning ved hjelp av sprengning medfører at vibrasjoner kan gjøre skade på ... -
TUNNELING ASPECTS OF THE WATERWAY SYSTEM AND STABILITY ASSESSMENT OF THE POWERHOUSE CAVERN FOR THE MINAS-SAN FRANCISCO HPP
(Master thesis, 2018)The future trend of energy supplies is gradually moving from fossil fuels to renewable and sustainable energy sources. In this context, hydropower is one of the best options to supply the base load and meet the energy ... -
Tunnelkonsept for Fornebubanen - Bør Fornebubnanen fremføres i ett eller to tunnelløp
(Master thesis, 2015)Fornebubanen er en ny T-banelinje som planlegges mellom Fornebu i Bærum og Majorstuen i Oslo, med nye stasjoner i Bærum, på Lysaker, på Vækerø og på Skøyen. Banen planlegges i sin helhet under bakken med midtplattformer ... -
Tunnelling challenges in Nepal
(Chapter, 2004)Nepal is a landlocked mountainous country with a population of approximately 23 millions. Being steep in topography and having many rivers originating from the glaciers of the Himalaya, Nepal has been gifted in the field ... -
Tunnelstein som ressurs
(Master thesis, 2020)I Noreg vert det kvart år teke ut om lag 19 millionar tonn stein frå driving av tunnelar. Samtidig minkar norske grus- og sandførekomstar, og transportavstandar for byggeråstoff aukar. Mengda tunnelstein frå norske ... -
Turbo-compressors for R-718: Experimental evaluation of a two-stage steam compression cycle
(Chapter, 2019)Water (R-718) is a safe and energy-efficient refrigerant. Mechanical vapour recompression (MVR), an open-loop heat pump using R718, can significantly reduce the energy consumption for steam-heated processes like drying, ... -
