  1. 11. Infrared spectroscopy studies of adsorption and photochemistry on TiO2 surfaces : From single crystals to nanostructured materials

    Författare :Andreas Mattsson; Lars Österlund; Per-Anders Carlsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

    Sammanfattning : TiO2 based photocatalysis is a green nanotechnology that can be used for removal of pollutants from water and air, as well as making synthetic fuels from water and carbon dioxide. Said photocatalysis has received major research interests during the last decades. LÄS MER

  3. 12. Essays on total factor productivity (TFP)

    Författare :Pontus Mattsson; Jonas Månsson; Lars Behrenz; Linnéuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; conditional difference-in-difference cDID ; Data Envelopment Analysis DEA ; District courts; Malmquist index; subsidized employment; Total factor productivity TFP ; Törnqvist TFP index; Economics; Nationalekonomi;

    Sammanfattning : This thesis consists of two self-contained empirical essays. Essay I investigates the impact of labor subsidies on TFP, and profit per employee is included as a second outcome. Coarsened exact matching (CEM) is performed on the key variables. After matching, a difference-in-difference (DID) model is applied. LÄS MER

  4. 13. Offset Management for Large Systems : A Multibusiness Marketing Activity

    Författare :Magnus Ahlström; Lars-Gunnar Mattsson; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Offset; countertrade; industrial co-operation; systems selling; project marketing; package deal; turnkey; buying behaviour; governmental procurement; local content;

    Sammanfattning : Offset, an advanced form of countertrade, is common in the international marketing of large infrastructure and defence systems. Offsets are activities that benefit the buying country for example in the form of local content, support of exports, subcontracts and technology transfer. LÄS MER

  5. 14. Empirical Essays on Railway Infrastructure Costs in Sweden

    Författare :Mats Andersson; Lars-Göran Mattsson; John Preston; KTH; []
    Nyckelord :Railways; Infrastructure; Marginal Costs; Maintenance; Renewal; Econometrics; Panel Data; Survival Analysis; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : The subject of this thesis concerns pricing the use of transport infrastructure. We are empirically investigating the relationship between railway traffic volumes and infrastructure management costs. More specifically, we are interested in estimating the change in infrastructure management costs from marginal variations in traffic volumes, i.e. LÄS MER

  7. 15. Enhanced image analysis, a tool for precision metrology in the micro and macro world

    Författare :Bita Daemi; Lars Mattsson; Peter Ekberg; Mikael Sjödahl; KTH; []
    Nyckelord :Image processing; image metrology; precision metrology; image correlation; subpixel; accuracy; uncertainty; Production Engineering; Industriell produktion;

    Sammanfattning : The need for high speed and cost efficient inspection in manufacturing lineshas led to a vast usage of camera-based vision systems. The performance ofthese systems is sufficient to determine shape and size, but hardly to an accuracylevel comparable with traditional metrology tools. LÄS MER
