Att skriva en avhandling är som att bege sig på en resa till ett främmande land. Vägen dit är lång och tidsåtgången stor, men vid målet väntar en skatt som ersätter (nästan) alla mödor och våndor. Resenären (det är doktoranden) har ingen större önskan än att ge sig ut på denna resa, men han/hon är beroende av en finansiär (d v s universitetet/fakulteten/institutionen och dess förlängda arm: handle

This thesis concerns the activity of expressing understanding with words. The overall aim is to explore, analyse and describe how 64 children aged 6, 10 and 14 expressed their understanding of certain physical phenomena in reflective dialogues. In the dialogues, the children were asked to reflect over expressions which they had used to explain their conception of the problem. Four studies were con

The low throughput at IC (Integrated Circuit) testing is mainly due to the increasing test data volume, which leads to high ATE (Automatic Test Equipment) memory requirements and long test application times. In contrast to previous approaches that address either test data compression or abort-on-fail testing, we propose an architecture for combined test data compression and abort-on-fail testing.

Popular Abstract in Swedish Mycket av dagens forskning inom astrofysik handlar på ett eller annat sätt om att förstå hur universum i allmänhet och vår galax i synnerhet fungerar. Var och hur har de grundämnen bildats som finns i stjärnor, planeter, gasmoln, på jorden och i våra kroppar? Det dominerande, och framgångsrika, sättet att ta reda på hur avlägsna astronomiska objekt ser ut och är uppbyggEta Carinae is one of the most massive and luminous stars in the Galaxy. A huge bipolar nebula and an equatorial disk give the object a characteristic shape. Close to the star there are gas clouds, which emit intriguing emission line spectra. One such region, the strontium filament, is studied in more detail in this thesis, and the identities of 600 emission lines are reported. Some of these requi

Pancreas transplantation is today a technically successful procedure and provides an alternative to insulin injections for the treatment of Type I diabetes mellitus. This thesis was undertaken while pancreas transplantation was developing and while several fundamental questions were being asked about both endocrine and exocrine drainage of the transplanted pancreas as well as how best to diagnose

The Swedish National Road Administration SNRA is responsible for the long term de-velopment of the road transport system, and spends large sums on road construction and 'operation and maintenance'. Improvements in efficiency which are small in per-centage terms therefore yield relatively large monetary effects. In order to create and maintain a strong and competitive road construction sector and a
