26. Floating-Point Analog-to-Digital Converter
Sammanfattning : To deal with the wide dynamic rage necessary for a radio receiver or corresponding applications, but to avoid impractically high resolution at high data rates, the approach of using a floating-point analog-to-digital converter (FP-ADC) has been investigated. This approach de-links the dynamic range with the resolution, and a very wide dynamic range can be achieved by an ADC with a moderate resolution. LÄS MER
27. Absolute Asymmetric Synthesis
Sammanfattning : Absolute asymmetric synthesis is the synthesis of optically active products from achiral or racemic precursors only. This has generally been regarded as impossible and is relevant in the discussion of the origins of biomolecular homochirality. LÄS MER
28. Satellite Radar Altimetry for Determination of Geoid Undulations and Gravity Anomalies
Sammanfattning : The sea level changes both temporally (due to dynamic effects) and spatially (due to sea bottom topography and inhomogeneities in the Earth's crust). Satellite radar altimetry is a remote sensing technique which can be used for e.g. determination of the instantaneous and mean sea level, and gravity anomalies at sea. LÄS MER
29. Separation of Proteins with Capillary Electrophoresis in Coated Capillaries with and without Electroosmosis : Studies on Zone Broadening and Analytical Performances
Sammanfattning : Proteins have such structural features that they may interact with different types of surfaces by all possible forces, i.e., electrostatic, hydrogen bonding, hydrophobic. In this thesis two different types of coatings for fused silica capillaries aimed to eliminate such interactions have been studied. LÄS MER
30. A Broad View on the Interpretation of Electromagnetic Data (VLF, RMT, MT, CSTMT)
Sammanfattning : The resolution power of single Very Low Frequency (VLF) data and multi-frequency Radiomagnetotelluric (RMT) data in delineating conductive structures typical for the sedimentary cover and crystalline basement in Scandinavia is studied with a view to future developments of the technique to increasing the frequency range into the LW radio band. Airborne and ground VLF data are interpreted and correlated with RMT measurements made on the ground to better understand the resolution power of VLF data. LÄS MER
