6. Resonance sensor technology for detection of prostate cancer
Sammanfattning : Prostate cancer is the most common type of cancer in men in Europe and the USA. Some prostate tumours are regarded as stiffer than the surrounding normal tissue, and therefore it is of interest to be able to reliably measure prostate tissue stiffness. The methods presently used to detect prostate cancer are inexact, and new techniques are needed. LÄS MER
7. Extremely low and microwave frequency electromagnetic fields : influence on biological systems
Sammanfattning : .... LÄS MER
8. Time-Frequency Analysis in Attosecond Spectroscopy
Sammanfattning : This thesis deals with ultrafast dynamics of electronic processes in rare gas atoms. The processes we explore include photoemission, where we time the emission of electrons moving away from the atomic core following ionization by a photon; and auto-ionization, where the atom spontaneously releases an electron wave-packet following photo-excitation.

9. Precision molecular spectroscopy in the near- and mid-infrared using frequency comb-based Fourier transform spectrometers
Sammanfattning : Absorption spectroscopy is a powerful scientific tool for non-invasive and remote sensing applications ranging from atmospheric monitoring to astrophysics. In spectroscopic detection schemes it is necessary to have spectral models for any molecular species to be detected or quantified. LÄS MER
10. Low Frequency Acoustic Excitation and Laser Sensing of Vibration as a Tool for Remote Characterization of Thin Sheets
Sammanfattning : There is a need to monitor the existence and effects of damage in structural materials. Bulk components provide a much publicized example, but the need exists in a variety of other structures, such as layered materials used in food packaging industries. LÄS MER
