41. Symmetry Filters Applied to Fingerprints : Representation, Feature extraction and Registration
Sammanfattning : A common framework for feature extraction in fingerprints is proposed by use of certain symmetries. The proposal includes representation, filters, and filtering techniques for common features including minutiae points, singular points and the ridge and valley patterns. LÄS MER
42. Orientation of fibres in suspensions flowing over a solid surface
Sammanfattning : The orientation of fibres suspended in a viscous fluid, flowing over a solid surface, has been studied experimentally. A shear layer was generated, by letting the suspension flow down an inclined plate. LÄS MER
43. Biosensor surface chemistry for oriented protein immobilization and biochip patterning
Sammanfattning : This licentiate thesis is focused on two methods for protein immobilization to biosensor surfaces for future applications in protein microarray formats. The common denominator is a surface chemistry based on a gold substrate with a self-assembled monolayer (SAM) of functionalized alkanethiolates. LÄS MER
44. Ultrastructural Aspects of Pulp Fibers as Studied by Dynamic FT-IR Spectroscopy
Sammanfattning : Dynamic (or 2D) FT-IR spectroscopy in combination withpolarized IR irradiation has been used in this work to studywood polymer orientation and interactions on theultrastructural level in wood fibers in the native state aswell as the effects of different pulping processes. The woodpolymer interactions were studied under both dry and humidconditions. LÄS MER
45. Magnetic map sense in animals: effects of geographic and magnetic displacements
Sammanfattning : Migration research is a large and diverse field and in my thesis I have focused on the impact of geomagnetic cues on animal orientation, navigation and migratory fuelling. Several animal species from widely different taxa possess the ability to sense and make use of geomagnetic information during migratory or homing events. LÄS MER
