En studie på spridning av partiklar genererade från brand
… of both PAH and metals, which is consistent with earlier analyses. Her column experiments with particles in the size ? 11 microns and ?100 microns in silica sand, reviled that the larger particles was immobilized because the transportation was influenced by sieving or …
This report is about the experiments with mixing of the separated water and the vacuum pump seal water at Hellisheiði power plant. This is done to prevent silica scaling and clogging in pipes and reinjection wells as well as eliminating vacuum pump seal water from the plant. The …
… years. Secondly, wood that had been dead for several decades. In the burning experiments, logs of approx. 1 meter were exposed to fire while standing. Small-diameter branches and twigs were used as fuel to simulate a passing flame front. Exposure time (flame contact with the …
En utvärdering av Google och Argos med frågor från en akademisk ämnesdisciplin
… of the concept of relevance, the study is performed with five different experiments with five different definitions of relevance. The formula for calculating the metrics measures precision with weights for ranking effectiveness. Wilcoxon's signed rank test is used to control if …
… in which we use the direction of analysis of the content of sixteen evaluation experiments. Our results indicate fundamental differences in the way the researchers are tackling the problem of evaluation of Web search engines. We think that, despite the differences that we have …
… environment to work with we have used a video system called QMPEGv2. A set of experiments were carried out to evaluate the performance of the algorithm. Through experiments, we show that the system can adapt to dynamic changes in network conditions and provide almost always the …

… from the analyses I sketch an historical line between the predecessors of the experiments with the poetic language in the past, starting with Mallarmé, and the experiments of today. My essay will in conclusion discuss the language poetry in a wider philosophical point of view …
avskiljning med mineraliska filtermaterial
… and nepheline. The experiment was carried out in two sets, starting with batch experiments followed by a column study. The objective of the batch experiments was to find out how variations in pH affected the sorption capacity of the materials. The interval used during the test …
… ways of communication, implicit and explicit. To compare the two methods, two experiments have been executed. The result of the experiments have been compared and discussed. There has also been an attempt made to combine the two methods.
effekter av ökad vattentillgång
… regulated in a high extent by local micro environmental conditions. Previous experiments suggest increased growth of H. splendens following water treatment compared to untreated shoots. The purpose of this study was to investigate how length and biomass growth of H. splendens is …

… development than the more conventional planting method. This study evaluated experiments that focused on direct seeding of spruce in the northern Sweden. Skogforsk set-up the experiments in Gideå and Sävar in 2003. They were inventoried in the spring and autumn of 2004. The …
Study of a detector by a signal detection theory
… from the detector. To be able to identify the causes of the false alarms two experiments was implemented. 180 persons participated, they were divided into three subgroups. In the other experiment 400 persons participated, of whom 200 was female and 200 male. Astonishing to see …
… characteristics have been evaluated through calculations and practical experiments. The changes have included the compressor and heat exchanger mountings, the compressor suction and discharge line piping and also pulsation dampening. The results of the experiments show that the …
… been developed at Maquet Critical Care AB, to reduce costly and time-consuming experiments on animals. The device simulates human lungs regarding lung dynamics and volume, uptake of anaesthetic agents and the production of carbon dioxide, heat and moisture. Further demands on …
