1. Polar auroral arcs
Sammanfattning : .... LÄS MER
2. Optical Studies of Periodic Microstructures in Polar Materials
Sammanfattning : The optical properties of matter are determined by the coupling of the incident electromagnetic radiation to oscillators within the material. The oscillators can be electrons, ions or molecules. Close to a resonance the dielectric function exhibits strong dispersion and may be negative. LÄS MER
3. Viral Loop Dynamics in Temperate and Polar Freshwaters
Sammanfattning : All cellular organisms in aquatic environments are susceptible to virus attack. Viruses are the smallest but most abundant biological entities in freshwaters. This thesis describes interactions between viruses and bacteria in temperate and polar freshwaters with particular emphasis on Arctic and Antarctic aquatic systems. LÄS MER
4. Low Noise Oscillator in ADPLL toward Direct-to-RF All-digital Polar Transmitter
Sammanfattning : In recent years all-digital or digitally-intensive RF transmitters (TX) have attracted great attention in both literature and industry. The motivation is to implement RF circuits in a manner suiting advanced nanometer CMOS processes. To achieve that, information is encoded in the time-domain rather than voltage amplitude. LÄS MER
5. Theoretical Studies of Simple Polar Fluids
Sammanfattning : Fluids composed of dipolar molecules are ubiquitous in nature, with water being the most prominent example. Due to their great importance and large complexity, a basic scientific understanding of the structure and thermodynamics of polar fluids is essential. LÄS MER
