1. Lefschetz Properties of Monomial Ideals
Sammanfattning : This thesis concerns the study of the Lefschetz properties of artinian monomial algebras. An artinian algebra is said to satisfy the strong Lefschetz property if multiplication by all powers of a general linear form has maximal rank in every degree. If it holds for the first power it is said to have the weak Lefschetz property (WLP). LÄS MER
2. Quantum Devices from the Assembly of Zero- and One-Dimensional Building Blocks
Sammanfattning : This thesis describes novel methods for the fabrication of nanometer-scale electronic devices, such as single-electron transistors and resonant tunneling diodes, from wire- and dot-shaped building blocks. The first part of the thesis describes the manipulation of metal nanoparticles and carbon nanotubes using an atomic force microscope. LÄS MER
3. Multitemporal Remote Sensing for Urban Mapping using KTH-SEG and KTH-Pavia Urban Extractor
Sammanfattning : The objective of this licentiate thesis is to develop novel algorithms and improve existing methods for urban land cover mapping and urban extent extraction using multi-temporal remote sensing imagery. Past studies have demonstrated that synthetic aperture radar (SAR) have very good properties for the analysis of urban areas, the synergy of SAR and optical data is advantageous for various applications.

4. Computational Solid Wave Propagation Numerical Techniques and Industrial Applications
Sammanfattning : For wave propagation and many other physical phenomena, the dynamic effects are vital. In industrial applications, such problems are very complex and generally have to be treated by means of numerical methods. LÄS MER
5. Carbon Dioxide: The Unknown Factor in the Atmospheric Corrosion of Light Metals. A Laboratory Study
Sammanfattning : The atmospheric corrosion of Al and Mg-Al alloys was investigated using controlled air in the laboratory. The effects of CO2, temperature, NaCl, relative humidity, SO2, NO2 and O3 on corrosion rate and corrosion product composition were examined. LÄS MER
