Background: In today’s globalized world, many producing companies depend on large supplier networks. Supplier relations require maintenance and a tool for that is supplier auditing. ABB is a leader in power and automation technologies that enable industrial customers to improve performance while lowering environmental impact. ABB business division Process Automation (PA) and business unit Control

Populärvetenskaplig sammanfattning: Satelliter används ofta för att studera markanvändning och vegationsutbredning. För att öka satelliternas möjlighet att kvantifiera vissa parameterar hos vegetationen har en strålningsmodell utvecklats. Dessa modeller simulerar den reflekterade strålningen som satelliten registrerar. På grund av att reflektansprocessen är så kompliserad kräver modellen en stor m

Populärvetenskaplig sammanfattning: Rassepautasjtjåkka är ett litet bergsmassiv beläget i norra Lappland. I massivet återfinns fyra stora nischer strax under glaciationsgränsen. Dessa nischer har en gång blivit uteroderade av glaciärer, men idag återfinns endast perenna snölegor i området. Skillnaden mellan en glaciär och en perenn snölega är att en glaciär har intern rörelse. En tjocklek på cirkaSince the mid 1970s the general retreating trend for glacier in Scandinavian have ceased and some glaciers have even started to advance. This is due to a more maritime influence on the climate, which means increased precipitation in winter and lower summer temperature. A more maritime climate can be said to be favourable for glacier growth. Under such climate conditions is it possible that new gla

Populärvetenskaplig sammanfattning: Under alla tider har planeten Jorden genomgått en naturlig klimat variation. Utöver denna naturliga variation i klimatet, så har människan, under det senaste århundradet, medverkat till en ökning av växthusgaser i atmosfären. Detta kan innebära att växthuseffekten intensifieras och Jorden bli utsatt för onaturliga temperaturökningar. Koldioxid (CO2), från bland In the context of climate change, it is important to understand how the terrestrial carbon cycle is interacting with the anthropogenic increase in atmospheric carbon dioxide (CO2) concentration. Boreal and subarctic regions in the northern hemisphere are great carbon pools, as well as they are subject to predicted warming. These facts place them in the absolute frontline of ecosystems that are to

Populärvetenskaplig sammanfattning: Jordens klimat är ett aktuellt forskningsämne. För att komma fram till resultat som är globalt applicerbara bedrivs forskning för att öka förståelsen och kunskapen om återkopplingsmekanismer mellan klimat och vegetation på många platser runt om i värden och i olika klimatzoner. Sedan början av 1900-talet har det pågått forskningsstudier (av ekosystemprocesser) iThis report investigates the utilization of digital camera images (DCIs), sensitive in the visible part of the spectrum, for documentation of seasonal and inter-annual variations in snow cover and plant phenology. The DCIs used were transformed to orthographic images (ortho-image) from ordinary oblique DCIs taken between January 2001 and December 2003 at a sub- arctic mire (Stordalen) in northern

People have become more and more mobile as a result of advancements in wireless communications technologies. The mobile phone as an enabler of this increased mobility has become an ever more important part of our society but comparatively little research has been done concerning mobile services at the organisational level as opposed to the individual level. With our study we wish to contribute to

One of the most important topics in financial literature is the Efficient Market Hypothesis (EMH). Recent financial research has questioned this hypothesis, and many authors have reached the conclusion that a contrarian strategy creates abnormal positive returns. In other words a strategy profiting buying losers and selling winners. To explain this market behaviour researchers have come up with a

As the title implies this study builds upon earlier research in the area to obtain an increased understanding of the determinants of smoking. Starting from the household production model (Becker 1965; Grossman 1972), the decisions of smoking participation and intensity of cigarette consumption are estimated in two sets of Two-part Models (2PM). Due to the characteristics of the data – the first th

This essay aims to examine whether there is a partisan influence on local government spending using three different measures, ideology, fragmentation and constellations of government. The ideology measure examines the share of socialists (left-wing parties) in the council. Fragmentation consists of a Herfindahl index which uses information on number of parties in the council and their respective s
