The main focus of this thesis has been to explore how the PFG NMR technique for diffusion measurements can be used to obtain useful information from various systems. The investigated systems have one thing in common; they belong to the general field of surface and colloid chemistry. The thesis is divided in two parts: one section is a summary and the other section contains four publications from

In the present work the feasibility of using various optical/laser based techniques for characterization of the afterburner of a full-size aircraft engine have been investigated. The tests have been performed on-site at Volvo Aero Corporation and were mainly directed towards surface thermometry using thermographic phosphors and fuel visualization. All applications were studied for different engine

The Functional Mockup Interface (FMI) is a tool independent standard for the exchange of dynamic models and for co simulation. The first version, FMI 1.0, was published in 2010. Already more than 30 tools support FMI 1.0. In this paper an overview about the recently published version 2.0 of FMI is given that combines the formerly separated interfaces for Model Exchange and Co-Simulation in one sta

A new concept of treating abdominal aortic aneurysms was studied during a three-year period. Instead of open repair, graft insertion was accomplished endovascularly from the groins. The graft was attached by expandable stents to the non-dilated infrarenal aorta, i.e. the aneurysmal neck, and to the iliac artery/ies. Pre- and postoperative work-up included CT-scanning, angiography and ultrasonograp

In this paper we describe a systematic study on long-term evolution of residential broadband Internet traffic covering 5 calendar years from June 2007 to May 2011. The traffic evolution is characterized both in the term of the total traffic volume, as well as the traffic volumes and shares for different application categories (file sharing, video streaming etc.), with the focus on comparing the tr

Internationellt sett har de fackliga organisationerna i Sverige på flera sätt mycket goda förutsättningar att verka för hållbara arbetsplatser. Hit hör den höga organisationsgraden, den välutbyggda fackliga arbetsplatsorganisationen, en relativ frånvaro av facklig rivalitet samt den långa traditionen av samarbete mellan arbetsmarknadens parter. Sedan 1990-talet förefaller facken på många arbetspla
