A Hybrid Numerical Method for 3D Multiphysics Modeling of Ultrasonic Transit-Time Flowmeters : Including Sound Propagation in Real Pipe Flows
(Doctoral thesis, 2023-10-20)Ultralyd mengdemålere av typen Ultrasonic Transit-Time Flowmeters (UTTF) og deres modellering er hovedfokus i denne avhandlingen. UTTF kan kategoriseres i clamp-on og inline-målere avhengig av behovene til applikasjoner ... -
Hybrid Transformer Network for Deepfake Detection
(Chapter, 2022)Deepfake media is becoming widespread nowadays because of the easily available tools and mobile apps which can generate realistic looking deepfake videos/images without requiring any technical knowledge. With further ... -
Hybrid visibility compositing and masking for illustrative rendering
(Peer reviewed; Journal article, 2010-08)In this paper, we introduce a novel framework for the compositing of interactively rendered 3D layers tailored to the needs of scientific illustration. Currently, traditional scientific illustrations are produced in a ... -
Hybridization between the locally endangered Rosa spinosissima and Rosa mollis results in the pentaploid Rosa × sabinii in Western Norway
(Peer reviewed; Journal article, 2016-12)Rosa spinosissima is an endangered species in Norway, found only within a limited area on the southwestern coast. Presumed hybrid forms between R. spinosissima and rose species within R. sect. Caninae have been recorded ... -
Hybridkapital - Skillet mellom gjeld og egenkapital (i relasjon til rentefradragsregelen i sktl. § 6-40)
(Master thesis, 2021-01-04)Oppgaven tar for seg det skatterettslige skillet mellom gjeld og egenkapital, i relasjon til rentefradragsregelen i sktl. § 6-40. Grensedragningen aktualiseres ved ulike former for hybridfinansiering. -
Hybrids between common and Antarctic minke whales are fertile and can back-cross
(Peer reviewed; Journal article, 2013-04-15)Background: Minke whales are separated into two genetically distinct species: the Antarctic minke whale found in the southern hemisphere, and the common minke whale which is cosmopolitan. The common minke whale is further ... -
Hybrids in Art. Theoretical perspectives on art in the age of genetics :The Transgenic art of Eduardo Kac
(Master thesis, 2011-05-15)This thesis explores the art form of "transgenic art", a term coined by artist Eduardo Kac at the turn of the millennium. Transgenic art is a strand of bio art specifically seeking to cross (often extremely different) ... -
Hydratdannelse og metanproduksjon fra gasshydrat - produksjonsmetoder og resistivitetsutvikling
(Master thesis, 2009-11-20)Ved høye trykk og lave temperaturer kan vannmolekyler danne strukturelle bur rundt et gjestemolekyl. Denne substansen er da i fast form og kalles hydrat. I naturlig forekomst av gasshydrat er metan det vanligste gjestemolekylet. ... -
Hydrate Formation and CH4 Production from Natural Gas Hydrates - Emphasis on Boundary Conditions and Production Methods
(Master thesis, 2009-05-13)Natural gas hydrate is a solid state of gas and water at low temperature and high pressure. Gas hydrates are known to form hydrate plugs in production line, and has thus generally been considered a problem to the oil ... -
Hydrate formation and CO2 - CH4 exchange in sandstone - An experimental study with emphasis on the role of initial brine saturation and salinity
(Master thesis, 2013-06-01)Recent research activity has demonstrated the viability of producing methane from gas hydrate bearing sediments by injecting and sequestering CO2 in a process where CO2 replace methane in gas hydrate by a process called ... -
Hydrate Monitoring using Capacitive Sensors
(Master thesis, 2013-06-02)Gas hydrates are of particular interest in petroleum industry since their formation during oil-production can be a major risk factor. Gas hydrates can block pipelines, interrupt production, and in worst case even cause ... -
Hydrate Nucleation, Growth, and Induction
(Journal article; Peer reviewed, 2020)The first stage of any phase transition is a dynamic coupling of transport processes and thermodynamic changes. The free energy change of the phase transition must be negative and large enough to also overcome the penalty ... -
Hydrate Phase Transition-Risk, Energy Potential and CO2 Storage Possibilities
(Doctoral thesis, 2022-02-11)Natural gas hydrate (NGH) can cause crucial flow assurance problems to the oil and gas industry. It is being considered as a potential vast energy resource for the world in the future. It could also potentially provide a ... -
Hydrate Plugging and Flow Remediation during CO2 Injection in Sediments
(Journal article; Peer reviewed, 2020)Successful geological sequestration of carbon depends strongly on reservoir seal integrity and storage capacity, including CO2 injection efficiency. Formation of solid hydrates in the near-wellbore area during CO2 injection ... -
Hydrate Production Philosophy and Thermodynamic Calculations
(Journal article; Peer reviewed, 2020)The amount of energy in the form of natural gas hydrates is huge and likely substantially more than twice the amount of worldwide conventional fossil fuel. Various ways to produce these hydrates have been proposed over the ... -
Hydro Investment (A Long-Term Policy to Mitigate Load Shedding in Nepal)
(Master thesis, 2019-06-21)Background: Nepal has been facing acute load shedding problem though it has a large potential for hydropower generations. It has more than 6,000 rivers with commercially exploitable hydropower generating potential of about ... -
