    Sammanfattning : Coherent multidimensional spectroscopy (CMDS) is the most complete nonlinear optical technique based on the interaction of multiple short laser pulses with matter. It has grown to play a significant role in studies of optoelectronic materials and pigment protein complexes. LÄS MER

  4. 3. Analysis of PCBs with special emphasis on comprehensive two-dimensional gas chromatography of atropisomers

    Författare :Mikael Harju; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; PCB; Atropisomers; Chiral; GC×GC; Enantiomeric barriers; Seal; polar; shape selective; Cyclodextrin; 2D; ECD; FID; TOF-MS; Comprehensive two-dimensional GC; Miljökemi; Environmental chemistry; Miljökemi; analytisk kemi; Analytical Chemistry;

    Sammanfattning : There are 209 PCB congeners, 136 of which have been found in technical PCB mixtures and hence may be found in the environment as a result of either intentional or unintentional release. The identification and quantification of the congeners are difficult due to analytical bias from coeluting PCBs and other persistent organic pollutants. LÄS MER

  5. 4. Estimating Human Limb Motion Using Skin Texture and Particle Filtering

    Författare :Björn Holmberg; Håkan Lanshammar; Virgil Stokes; Christopher L. Vaughan; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Human motion analysis; Skin texture; Monte Carlo estimation; Particle filter; Mutual Information; Simulated Annealing; Marker-free; Rigid body transformation; 2D correlation; Systems engineering; Systemteknik;

    Sammanfattning : Estimating human motion is the topic of this thesis. We are interested in accurately estimating the motion of a human body using only video images capturing the subject in motion. Video images from up to two cameras are considered.The first main topic of the thesis is to investigate a new type of input data. LÄS MER

  7. 5. Revealing Electronic Structures of 2D Molecular Crystals and Correlating Them with Optoelectronic Properties

    Författare :Qingqing Wang; Mats Fahlman; Xianjie Liu; Heiko Peisert; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 2D molecular crystals; Crystal engineering; Electronic structure; Organic field effect transistors;

    Sammanfattning : Electronic band structure serves as the foundation for understanding the physics of semiconductors. The electronic band structure of inorganic semiconductors has been well understood based on ideal single crystal samples, thus actually laid the foundation for the prospering development of inorganic semiconductor devices.
