21. Terrain Modelling with GIS for Tectonic Geomorphology : Numerical Methods and Applications
Sammanfattning : Analysis of digital elevation models (DEMs) by means of geomorphometry provides means of recognising fractures and characterising the morphotectonics of an area in a quantitative way. The objective of the thesis is to develop numerical methods and a consistent GIS methodology for tectonic geomorphology and apply it to test sites. LÄS MER
22. Computational methods for microfluidics
Sammanfattning : This thesis is concerned with computational methods for fluid flows on the microscale, also known as microfluidics. This is motivated by current research in biological physics and miniaturization technology, where there is a need to understand complex flows involving microscale structures. Numerical simulations are an important tool for doing this. LÄS MER
23. Spectral analysis and magnetic resonance spectroscopy
Sammanfattning : This dissertation is concerned with nonparametric approaches for spectral analysis (SA) and algorithms for magnetic resonance spectroscopy (MRS) data analysis.A method to obtain the optimal smoothing window for the class of SA methods based on local smoothing of the periodogram is proposed.

24. Spectral Analysis of Nonuniformly Sampled Data and Applications
Sammanfattning : Signal acquisition, signal reconstruction and analysis of spectrum of the signal are the three most important steps in signal processing and they are found in almost all of the modern day hardware. In most of the signal processing hardware, the signal of interest is sampled at uniform intervals satisfying some conditions like Nyquist rate. LÄS MER
25. Development and Applications of Chemometric Methods for Spectral Deconvolution
Sammanfattning : Chemometric methods are very useful in analyzing complex mixtures. In this thesis two methods are presented that allow resolution of overlapping spectra from mixtures without knowledge of the pure component spectra. It also includes applications of these methods, in which the spectroscopic properties of the fluorescein system are characterized. LÄS MER
