  2. 1. Lefschetz Properties of Monomial Ideals

    Author : Nasrin Altafi; Mats Boij; Alicia Dickenstein; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Weak Lefschetz property; monomial ideals; group actions; almost linear resolution; Mathematics; Matematik;

    Abstract : 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). READ MORE

    Author : Claes Thelander; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum devices; classical mechanics; quantum mechanics; relativity; statistical physics; thermodynamics; Matematisk och allmän teoretisk fysik; klassisk mekanik; kvantmekanik; relativitet; gravitation; termodynamik; statistisk fysik; Mathematical and general theoretical physics; single-electron transistor; nanowires; AFM; carbon nanotubes; Fysicumarkivet A:2003:Thelander;

    Abstract : 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. READ MORE

  5. 3. Multitemporal Remote Sensing for Urban Mapping using KTH-SEG and KTH-Pavia Urban Extractor

    Author : Alexander Jacob; Yifang Ban; Paolo Gamba; Francesca Bovolo; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; KTH-SEG; ASAR; HJ-1B; Urban Land Cover Mapping; OBIA; Segmentation; Image Classification; KTH-Pavia Urban Extractor; Urban Extent; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Abstract : 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.
