    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; corporate governance; power indices; dual class of shares; pyramidal structure; owner control; firm performance; voting premium; Shapley-Shubik power index; Banzhaf power index; capital structure; firm leverage; profitability; tangibility; panel data;

    Sammanfattning : This dissertation is divided into 4 essays. Each focuses on different aspect of firm risk and corporate governance issues. It mainly deals with corporate governance issues in the context of strong owner control and its implications to market efficiency. LÄS MER

  3. 2. Time Correlated Single Photon Spectroscopy on Pyramidal Quantum Dots

    Författare :Tomas Jemsson; Fredrik Karlsson; Per-Olof Holtz; Sytjugov Ilya; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Generation of non-classical light is both of fundamental interest and a common condition for quantum information applications (QIA). One feasible type of single photon emitter for QIA is based on semiconductor quantum dots (QDs), due to their atomic-like energy structure and their possibility to be integrated with other semiconductor devices on the same chip.

  4. 3. Synthesis and Structural Characterization of Copper(I) Complexes with Hard Donor Ligands

    Författare :Björn Gustafsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Acetonitrile; ­ -Sparteine; Chloride; co-ordination chemistry; Phenoxide; Alkene; Bromide; crystal structure; Copper I ; Amine;

    Sammanfattning : Syntheses and crystal structures of nine new copper(I) complexes and one novel mixed-valence copper(I/II) complex are reported: two homoleptic phenoxides and eight complexes with N-donor ligands. The copper(I) and the copper(I/II) phenoxide complexes have been prepared by reactions between mesitylcopper(I) and 2-allyl-6-methylphenol in toluene. LÄS MER

  5. 4. Improving fingerprint biometrics by local symmetry and fusion

    Författare :Hartwig Fronthaler; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alignment; Matching; Minutiae Extraction; Image Restoration; Multi-expert Fusion; Biometrics; Symmetry Features; Structure Tensor; Quality Assessment; Fingerprint Recognition; Image Pyramid; Enhancement; Rotational Symmetry; Cascaded Fusion; Monomodal Fusion; Fingerprint;

    Sammanfattning : Fingerprint recognition and biometrics in general have been significantly gaining attention within the last years, not least due to the biometric passport that has been introduced all over Europe and the American immigration management system US-VISIT. The tasks of fingerprint recognition can be broken down to smaller entities, i.e. LÄS MER

  7. 5. Heterometallic Oxo-Alkoxides of Europium, Titanium and Potassium

    Författare :Erik Berger; Gunnar Westin; Lars Eriksson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alkoxides; Europium; Lanthanoids; Electronic absorption spectroscopy; f-f spectroscopy; Coordination chemistry; Koordinationskemi; Inorganic Chemistry; Oorganisk kemi;

    Sammanfattning : Coordination compounds of europium and titanium with oxide, ethoxide (OCH2CH3), iso-propoxide (OCH(CH3)2) and tert-butoxide (OC(CH3)3) ligands have been studied. These belong to the general class of oxo-alkoxides, MxOy(OR)z, with alkoxide ligands (OR) containing an organic, aliphatic part R. LÄS MER
