  1. 1. Designing with Urban Sound : Exploring methods for qualitative sound analysis of the built environment

    Författare :Nina Hällgren; Katja Grillner; Björn Hellström; Gunnar Sandin; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; Architectue; urban sound design; urban sound planning; soundscape; urban planning; artistic research; architectural research;

    Sammanfattning : The licentiate thesis Designing with Urban Sound explores the constitution and qualitative characteristics of urban sonic space from a design-oriented and practice-based perspective. The act of lifting forth and illuminating the interaction between architecture, the creation of sound and a sonic experience aims to examine and develop useful tools and methods for the representation, communication and analysis of the exterior sonic environment in complex architectural spaces.

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

    Författare :Alexander Jacob; Yifang Ban; Paolo Gamba; Francesca Bovolo; KTH; []
    Nyckelord :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;

    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.

    Sammanfattning : The present dissertation describes the efforts directed towards the development of computational tools to support process modeling. This work is also a further development of the Thermoslag® software developed in the Division of Materials Process Science, KTH. LÄS MER

  4. 4. Corrosion-included metal runoff from external constructions and its environmental interaction : a combined field and laboratory investigation of Zn, Cu, Cr and Ni for risk assessment

    Författare :Sofia Bertling; Inger Odnevall Wallinder; Herbert E. Allen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Atmospheric corrosion; metal runoff; metal dispersion; soil; limestone; retention; Miljöteknik; Environmental engineering; Miljöteknik;

    Sammanfattning : The 1990s has seen an increased awareness of possible environmental effects of corrosion-induced metal release from outdoor constructions. Considerable efforts have been initiated to perform critical assessments of possible risks of selected metals. Gaps of knowledge have been identified and research investigations started. LÄS MER

  5. 5. Quantum chemical calculations of non-linear optical absorption

    Författare :Peter Cronstrand; KTH; []
    Nyckelord :quantum chemical; non-linear optical; multi-photon absorption;

    Sammanfattning : This thesis represents a quantum chemical treatise ofvarious types of interactions between radiation and molecularsystems, with special emphasis on the nonlinear opticalprocesses of Multi-Photon Absorption and Excited StateAbsorption. Excitation energies, transition dipole moments,two-photon and three-photon tensor elements have beencalculated from different approaches; density functional theoryandab-initiotheory, employing different orders ofcorrelation treatment with the purpose to provide accuratevalues as well as evaluate the quality of the lower ordermethods.
