A biophysical study of oscillatory water regulation in plants : measurements and models
(Doctoral thesis, 2001)In this thesis, several aspects of the water regulation of plants will be studied and discussed. The focus is on biophysical properties of the system, especially on the dynamics and qualitative mechanistics. Following this ... -
A Numerical Study of Capillary and Viscous Drainage in Porous Media
(Dr. ingeniøravhandling, 0809-103X; 1999:131, Doctoral thesis, 1999)This work concentrates on the flow properties when one fluid displaces another fluid in a network of pores and throats. We consider the scale where individual pores enter the description and we use a network model to ... -
A Study of Self-Consistent Equations of State

A TEM study of the precipitates in a 6082 Al-Mg-Si alloy system
(Dr. ingeniøravhandling, 0809-103X; 2000:103, Doctoral thesis, 2001)The purpose of this work has been to gain a better understanding of the details of the precipitation sequence in Al-Mg-Si alloys. Because of the complexity of such ternary systems is has been necessary to limit the study ... -
Adsorption of organic molecules at sufaces: A first principles investigation
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:81, Doctoral thesis, 2006)The adsorption of a molecule at a surface is a fundamental step in a wide variety of industrially relevant phenomena, including adhesion, corrosion, and catalysis. The work presented in this thesis is motivated by the ... -

Advancing Spintronics through Ellipsometric Characterisation of Surface Polaritons
(Doctoral theses at NTNU;2024:133, Doctoral thesis, 2024)Spintronics is a subtopic of magnonics in which the spin of the electron is used to store and process information. Magnonics is the magnetic analogue of the recently popularised field of plasmonics, which deals with the ... -
Aeronomy of hydroxyl airglow variability by means of high-resolution telescope observations and gravity wave simulations
(Doctoral theses at NTNU;2019:202, Doctoral thesis, 2019)Are there waves on the fjord right now? “Easy to find out”, you might think. Just go down to the water and have a look. Now imagine that you are in Oppdal, about 90 kilometres away, trying to see the waves on the fjord in ... -
An investigation of wave-energy absorption by single and double oscillating water-column converters
(Dr.ingeniøravhandling, 0809-103X; 1995:2, Doctoral thesis, 1995) -
Anisotropic depth migration of converted wave data, inversion of multicomponent data to estimate elastic parameters at the seafloor and one-dimensional data-driven inversion
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:210, Doctoral thesis, 2006)The increasing demand for oil and gas in the world today drives the need for new and improved methods for identifying hydrocarbon prospects. The petroleum industry uses information about the subsurface in the exploration ... -
Antiferromagnetic Insulator Spintronics
(Doctoral theses at NTNU;2019:343, Doctoral thesis, 2019)Summary: Spin currents can make your computer energy efficient and ultrafast Have you noticed that your laptop sometimes can get quite warm? Electronical devices rely on transfer of information via a charge current ... -

Atmospheric Tides in the Mesosphere and Lower Thermosphere: Meteor Radar Observations and Mechanistic Tidal Model Simulations
(Doctoral theses at NTNU;2022:131, Doctoral thesis, 2022)Atmospheric tides are global-scale waves whose periods are an integer fraction of a solar or lunar day. While the tides are primarily excited in the lower atmosphere, their amplitudes can become very large at high altitudes. ... -
Atomistic modeling of the Al-Mg-Si alloy system
(Dr. ingeniøravhandling, 0809-103X; 2003:28, Doctoral thesis, 2003)The atomic and electronic structure of bulk crystalline and solid state phases related to Al-Mg-Si (6xxx) alloys have been studied using Density Functional Theory (DFT) and total energy Tight Binding (TB). We present a ... -
Atomistic Scale Modelling of Defects in Aluminium Alloys
