16. Fourier transform and Vernier spectroscopy using optical frequency combs
Sammanfattning : Optical frequency comb spectroscopy (OFCS) combines two previously exclusive features, i.e., wide optical bandwidth and high spectral resolution, enabling precise measurements of entire molecular bands and simultaneous monitoring of multiple gas species in a short measurement time.

17. Development of wavelength modulation diode laser absorption spectrometry in transversely heated graphite atomisers for sensitive trace element analysis
Sammanfattning : The Wavelength Modulation Diode Laser Absorption Spectrometry technique (WM-DLAS) is a laser-based spectroscopic technique for sensitive detection of atoms and molecules that so far mostly has been used for environmental monitor-ing. This thesis is concerned with the development of this technique for sensitive trace element analysis. LÄS MER
18. Polymer/polymer blends in organic photovoltaic and photodiode devices
Sammanfattning : Organic photovoltaics devices (OPV) have attracted attentions of scientist for their potential as inexpensive, lightweight, flexible and suitable for roll-to-roll production. In recent years, considerable attention has been focused on new acceptor materials, either polymeric or small molecules, to replace the once dominating fullerene derivatives. LÄS MER
19. Credit risk and forward price models
Sammanfattning : This thesis consists of three distinct parts. Part I introduces the basic concepts and the notion of general quadratic term structures (GQTS) essential in some of the following chapters. Part II focuses on credit risk models and Part III studies forward price term structure models using both the classical and the geometrical approach. LÄS MER
