A theoretical review of the concept of vendor managed inventory is presented. The objective with the study is two fold. First of all the study tries to sort out the different terms connected with VMI and secondly former research about the VMI concept is presented.

Large-scale distributed networks are not easy to control centrally. Local set-point variations will likely create flooding alarm fluctuations. However, local control can cause emergence of unwanted network behavior. The paper overviews the problems with model-based control in sensory networks, such as currently rolled out for the Electric Grid, and shows how networked intelligence can bridge betwe

Popular Abstract in Swedish En anledning till att nya växtarter uppkommer är att närbesläktade arter korsar sig med varandra. Detta har skett i alla tider. Hybridisering (korsning) mellan arter kan utöver skapande av nya arter även medföra att mindre vanliga, kanske endemiska, arter inte överlever (en endem = en art som endast finns i ett mycket begränsat geografiskt område). Detta beror på genetiIn the present thesis, I investigated the inter- and intraspecific variation in the Silene vulgaris/uniflora species-complex (the bladder campions). I have focused on the effects of past and present hybridization both on a large scale ? over the whole of Europe ? and on a local scale. Silene vulgaris and S. uniflora are perennial herbs and they are interfertile. The results from my studies sugges

I syfte att väcka intresse för kemi och kemi/bioteknik sjösatte vi 2007 den kemiska julkalendern – en satsning riktad mot mellan- och högstadiet – där spektakulära experiment intar huvudrollen. Den kemiska julkalendern hade sin hemvist på LTH’s hemsida och en ny lucka kunde öppnas varje dag fram till julafton. Bakom varje lucka fanns en kort filmsnutt med ett kemirelaterat experiment, följt av en

Historical demography, which is the study of human population dynamics in the past, is central for understanding human behaviours and traits, such as fertility, mortality and migration. An important factor in demographic research is the geographic context. Where people lived often determined their social ties, exposure to diseases and economic development. Such information is essential not only fo

Popular Abstract in Swedish Växter får energi att växa till och fortplanta sig genom fotosyntes och cellandning. Vid fotosyntesen använder växterna ljusenergin från solen medan vid cellandningen kolföreningar bryts ner för att frigöra den energi som behövs till olika kemiska processerna i cellen. Enzymer är proteiner som katalyserar dessa kemiska processer. För att omvandla ett utgångsämne (t ex sMost cells are crowded with solutes, enzymes, nucleic acids, structural proteins and membranes. Crowding promotes macromolecular interactions and determines major properties of the cellular environment such as viscosity, diffusion and inhomogeneity. Macromolecular interactions that involve enzymes can affect the kinetic and regulatory properties of these, hence the interactions are part of the met

This paper presents the application of several optical measurement techniques for the characterization of the combustion behavior of the pilot burner of a gas turbine combustor developed according to the lean premixed prevaporized (LPP) concept. The vaporization of the kerosene fuel (Jet-A) and its consequent mixing with air has been visualized using combined Laser-Induced Fluorescence (LIF) and M
