This paper briefly summarizes a research project aiming at analyzing the scaling up of extreme programming (XP) in a market driven context for embedded software and the integration of XP towards management processes in this context. Both the scaling of XP and market driven software development issues are not addressed by the original XP methodology as it relies on developing software by simplifyin

The ammoxidation of propane is commonly regarded as being the future route for producing acrylonitrile, and the Mo-V-Nb-Te-oxide system studied here has thus far been seen as the most promising candidate for achieving this. Yields of up to 62% have been presented very elegantly in the patent literature. A great disadvantage has been, however, that the crystalline quality of the catalyst tends to b

The purpose of this paper was to present an empirical inquiry into the categorization of collision types based on contributing factors and severity distribution. This study used Connecticut crash data from selected two-lane roads originated from police reports from 1996 to 2001. K-means cluster analysis methodology was conducted to categorize 10 collision types into 4 groups according to the simil

Common practice in industry is to rotate the milling cutter in only one direction even though the geometry of the inserts are thus that they could be used again while the milling cutter is rotating in the opposite direction. The aim of this study was to investigate to what extent it is possible to increase the tool utilization during milling by first rotating the milling cutter in one direction un

Popular Abstract in Swedish Fåglar har fascinerat människor i århundraden. Färgen på deras fjädrar, deras flyghöjd och deras förmåga att fånga små byten har skapat den allmänna uppfattningen att fåglar har en fantastisk syn. Föreställningen att fåglar har skarpare syn än människor är väletablerad hos jägare och fiskare och finns att hitta i litteraturen. Det finns emellertid tusentals fågelarter oAvian eyes are big both in relative and absolute terms, thus the importance of vision to birds is obvious. Even though the general eye plan is rather conservative throughout the group, there is a great variation in visual capabilities. In this thesis I present four studies on different aspects of spatial vision in parrots, procellariiform seabirds and birds of prey. In Paper I we studied retinal g

This paper discusses how the gestural modality can contribute to our understanding of anaphoric linkage in learner varieties, focusing on gestural anaphoric linkage marking the introduction, maintenance, and shift of reference in story retellings by learners of French and Swedish. The comparison of gestural anaphoric linkage in native and non-native varieties reveals what appears to be a particula

Om filmen "Medan Beirut brann": Beirut den 13 april 1975, libanesiska inbördeskrigets första dag. Passagerarna på en palestinsk buss massakreras av milismän framför ögonen på Tarek och Omar, två tonåringar från västra Beirut, stadens muslimska del. De kristna kontrollerar östra Beirut och denna geografiska uppdelning längs "gröna linjen" - den demarkationslinje som löper genom staden - blir en sym

Although it is possible to measure respiration by intact tissues it is often useful to be able to isolate uncontaminated, intact and functional mitochondria. Here, we will consider some of the principles for isolating cell organelles. This discussion is not meant to be exhaustive nor will it be a cookbook with recipes to be followed step-by-step. Useful general references are Douce 1985, Møller et
