en litteraturstudie av ett forskningsområde inom information retrieval
… describe passage retrieval (PR), with basis in results from various empirical experiments, and to critically investigate different approaches in PR. The main questions to be answered in the thesis are: (1) What characterizes PR? (2) What approaches have been proposed? (3) How …
… the Lemnaceae site had an methane emission rate of 712 mg CH4 m-2d-1. In all experiments at the Typha site, the highest methane emission rate was obtained at sunrise.
en fallstudie av följderna av Stora Ensos försöksverksamhet med askåterföring
… a forest company, Stora Enso, and their experience from a number of trials and experiments with ash recycling. A literature survey and a total of eleven in-depth interviews were carried out. Ash recycling was found to be the concern of three different divisions of the company …
en experimentell studie
… de propositioner som är framlagda i teorikapitlet ligger till grund för de experimentsituationer som genomförts på en riskkapitalist och en företagsledare. Våra slutsatser kring propositionerna indikerar på att grunden i den specifika relation vi studerat baseras på principal ? …
… has become a common practice in forest management to optimise tree production. Experiments with nitrogen fertilisation have shown that the volume growths of the tree and litter supply have increased after fertilisation. There are also reports about the negative effects nitrogen …
… an ad hoc network where packet losses and partitions can be made. Simulation experiments show that we didn't get the problems we expected. This can be explained by low delays and because we buffered the packets during link failure. A simple modification of TCP was made and …
… partly by a comparison to the airplane’s inertial navigation system (INS). The experiments showed that GrafNav’s ability to estimate the position is comparable with PNAV:s, but its capacity to estimate the velocity is considerably worse. The velocity estimate even showed a more …
… is wrong. The pharmacological effects of Aqui-S need to be evaluated and more experiments need to be done before we can come to any conclusions about its effectiveness as an analgesic.
… topography were implemented in matlab. Simulations were compared with experiments documented in the literature. These showed that reported transitions between Cassie and Wenzel mode can be explained by minimization of the free energy. In this report, a study on the possibility …
… developed to whychemicals with certain properties maximize the ink adhesion. Experiments are performed but theresults are inaccurate. The reason for ink adhesion is still unknown.Paper treated with the candidate compound is produced in a production trial and the paper …
… Due to economic constraints only samples from the b2-adrenoceptor stimulator experiments were analysed. Following inhalation treatment of a horse using either inhalation mask, detectable levels of b2-adrenoceptor stimulator were measurable on some occasions in the urine of some …
… times, but with low effects on the beetles. Field trials and laboratory experiments showed that pollen beetles had developed resistance against pyrethroids. Between 2001 and 2003 several field trials were laid out in Östergötland to investigate pollen beetle mortality from …

… use of the areas increases the requirements in these aspects. Small-scale experiments in parks can give valuable experience and increase public awareness of the system’s purpose. The park employees asked were sceptical, although some were open to discuss experimental spreading …
en studie utförd vid Hovgårdens avfallsanläggning i Uppsala
… in the water. Also analyses of iron and manganese were done after the experiments with potassium permanganate, hydrogen peroxide and Fenton's reagent. The results showed a reduction of the UV absorbance in the leachate when potassium permanganate or Fenton's reagent demands a pH …
… both sides of the machine. We have done some field studies that includes some experiments and observations. In the experiment we have come to a result concerning the loss of sugarbeets behind the machine. We have been following the Ropa Maus for about five days during the …
