Cyclodextrin triggered dimensional changes of polysaccharide nanogel integrated hydrogels at nanometer resolution
(Journal article; Peer reviewed, 2013)High resolution monitoring of dimensional changes of cholesterol bearing pullulan (CHP) hydrogel was performed as a model for materials dimensional changes associated with drug delivery. Hydrogels consisting of methacryloyl ... -
Yb-Tm energy transfer in Y-codoped fibers
(Chapter, 2013)Experimental investigation of Yb-Tm energy transfer process in Yb/Tm-doped fibers with Y-codoping provided a fairly high energy transfer efficiency of 50 %, making lasers based on these glass fibers attractive for diode-pumping ... -
Parametric model of the Mueller matrix of a Spectralon white reflectance standard deduced by polar decomposition techniques
(Journal article; Peer reviewed, 2013)Decomposition methods have been applied to in-plane Mueller matrix ellipsometric scattering data of the Spectralon reflectance standard. Data were measured at the wavelengths 532 nm and 1500 nm, using an achromatic optimal ... -
Detection and Localization of High-Frequency Interception Signals using Compressive Sensing
(Master thesis, 2013)We investigate detection and localization of high-frequency interception signals underwater using a fairly new framework known as Compressive Sensing. Within this framework we can sample at sub-Nyquist rate and still be ... -
Numerical Simulations of Scattering of Light from Two-Dimensional Rough Surfaces Using the Reduced Rayleigh Equation
(Journal article; Peer reviewed, 2013)A formalism is introduced for the non-perturbative, purely numerical, solution of the reduced Rayleigh equation (RRE) for the scattering of light from two-dimensional penetrable rough surfaces. Implementation and performance ... -
Soft Matter Physics of Clays and Clay suspensions: structural arrest, ordering, and host-guest interactions
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:197, Doctoral thesis, 2013)This thesis contains fundamental experimental studies in soft matter physics, focusing on plate-shaped hectorite and uorohectorite clays as nanomaterials with applications in the formation of glasses, gels and liquid ... -
3D-EPI with parallel imaging acceleration along two Axis: Evaluated with Phantom Study and BOLD fMRI
(Master thesis, 2013)The function of the human brain has for many years been an intriguing field of research, and has led to the discovery of functional MRI (fMRI). fMRI is dependent on high spatial and temporal resolution to acquire detailed ... -
Mid-Infrared Femtosecond Laser
(Chapter, 2013)Recent breakthroughs in femtosecond lasers operating directly in the mid-infrared wavelength region enabled generation of Watt-level output with ~10-nJ pulses and only 5 optical cycles duration, demonstrating interesting ... -
Optimal Paths in Random Conductor Networks
(Master thesis, 2013)In this master thesis, the spanning path through a random conductor network with aquenched threshold distribuion has been studied. An argument is made using a hierar-chial model, that for bonds having a piecewise linear ... -
Gravity Wave Refraction in the Atmosphere:: Ray tracing versus Geometric Location from a Single Image
(Master thesis, 2013)This thesis presents two methods of finding the sources of gravity waves observed in the night-time hydroxyl airglow; ray-tracing and geometric localisation by fitting concentric circles onto the curvature of the gravity ... -
Topology of fracture networks
(Journal article; Peer reviewed, 2013)We propose a mapping from fracture systems consisting of intersecting fracture sheets in three dimensions to an abstract network consisting of nodes and links. This makes it possible to analyze fracture systems with the ... -
Sensitivity Analysis of O&M Costs for Offshore Wind Farms
(Master thesis, 2013)The offshore wind farm industry is challenged by high costs related to operation and maintenance (O&M), and a study on how to significantly reduce these costs is essential to make this industry competitive with other energy ... -
Low Rank States with Bound Entanglement in a System of three qubits
(Master thesis, 2013)We have studied mixed quantum states in the system of three qubits with the property that all their partial transposes are positive; these are called PPT states. We classify a PPT state by the ranks of the state itself and ... -
1 Watt femtosecond mid-IR Cr:ZnS laser
(Journal article; Peer reviewed, 2013)A room-temperature Kerr-Lens modelocked (KLM) Cr:ZnS laser generates <70 fs pulses duration (about eight optical cycles) with 5.6 nJ pulse energy and over 100 nm FWHM spectral width at 105-157 MHz repetition rates. The ... -
Nanoflow of Protons and Water in Polymer Electrolyte Membranes
(Master thesis, 2013)This master thesis studies the applicability of continuum mean-field theories such as the Poisson-Nernst-Planck equations and the Stokes equation. In particular, we investigate electro-osmotic flow of water and protons in ... -
The effect of ball-milling lithium hydride with lithium/rare-earth borohydrides: Synthesis, decomposition pathways and hydrogenation properties
(Master thesis, 2013)Mixed-metal borohydride hydrogen storage composites (3LiBH4 + LiLn(BH4)3Cl) and reactive hydride composites (6LiBH4 + LnH(2+x) (Ln = La, Yb) have been synthesized from LiBH4 and the corresponding rare rare-earth chlorides ... -
Implementing a Full-Band Monte Carlo Model for Zincblende Structure Semiconductors
