16. Light and X-ray scattering investigations of microtubules subjected to oscillating electric fields
Sammanfattning : I vårt dagliga liv blir vi utsatta för oscillerande elektriska fält av olika frekvenser. Dessa fält inkluderar mobiltelefoner, wifi, bluetooth, radar för navigering, radar från bilar, kommunikationssatelliter, samt GPS. LÄS MER
17. Shape-based Representations and Boosting for Visual Object Class Detection : Models and methods for representaion and detection in single and multiple views
Sammanfattning : Detection of generic visual object classes (i.e. cars, dogs, mugs or people) in images is a task that humans are able to solve with remarkable ease. Unfortunately this has proven a very challenging task for computer vision. LÄS MER
18. Moderna kvinnor : Modernitet, femininitet och svenskhet i svensk veckopress 1921 -1933
Sammanfattning : De moderna kvinnorna med korta kjolar och ännu kortare hår som jazzade sig igenom 1920-talets nöjesliv är en bild som reproduceras i populärkulturen än idag.

19. Towards a sustainable automotive industry : experiences from the development of emission control systems
Sammanfattning : From the mid-1970s and on, the contribution to air pollution of carbon monoxide, hydrocarbons and nitrogen oxides from gasoline passenger cars in the developed world has been reduced through co-evolution of regulation and commercial introduction of catalytic emission control technology, now part of hundreds of millions of cars, trucks and buses worldwide. This dissertation is a disaggregated study of the global introduction of catalytic emission control technology as a measure to reduce local air pollution. LÄS MER
20. Numerical Simulations of Cooling Concepts Related to Gas Turbine Combustors
Sammanfattning : The mean by which a gas turbine combustor is cooled is of major importance for the efficiency and emission performance of the machine. The trends of increasing top cycle temperature and leaner combustion have also been accompanied by a need of efficient use of the cooling air. LÄS MER
