Investigation of human movement in the past has been a confounding issue in archaeology. Direct measurement of past mobility has recently become feasible, however, through the application of strontium isotope analysis to human skeletal remains. In this study, we examine the question of changes in residence and place of origin among the inhabitants of the landscape of south-central Sweden. We focus

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

This article discusses the role of archaeology in our society as well as the epistemological outlook within archaeology. In order to illustrate the relevance of archaeology in our own age three topics are formulated - landscape archaeology, the long-term perspectives of archaeology and the norms and values of our particular system. It is underlines that archaeologists are interpreters of fragments

I kapitlet diskuteras samhällsfenomenet med att idag en ny form av tjänster, ledarskapsutveckling, kompetensutveckling och terapeutiska tjänster, erbjuds av privata företag eller enskilda entreprenörer utan att några krav på officiellt dokumenterad kompetens ställs.

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
