Feedback in server systems has during last years gained much interest in order to fulfill still increasing demands on performance and optimization regarding, for example, quality of service (QoS) requirements. In this paper we investigate a feedback–based prediction scheme for controlling a single server queue. This control structure has the benefit over other previously suggested control structur

We performed high-resolution simulations of two stellar collisions relevant for stars in globular clusters. We considered one head-on collision and one off-axis collision between two 0.6-Msolar main-sequence stars. We show that a resolution of about 100000 particles is sufficient for most studies of the structure and evolution of blue stragglers. We demonstrate conclusively that collision products

Adult education (vuxenutbildning) in Sweden is extensive and based on a long and strong tradition (more than 100 years). The Swedish strategy has for long time been education for everyone and it has been a conscious concentration that education is a way to strengthen and increase democracy and equality. Responsibility and decision making is carried out by institutions, municipalities and local org

Governments attempting to regulate labour markets and control immigration are confronted with difficult questions. In the past, there was general agreement that the asylum system should not be exploited as a side entrance to the labour market. The two systems—asylum and labour market—were to be planned and maintained separately. But if migration is a prerequisite for asylum, does not increasingly

Six depression rating scales, GDS, Zung, CES-D, CPRS-D and Cornell, were compared in 40 patients. The validity was good for all scales except for the Cornell scale. A comprehensive investigation was done in 116 elderly stroke patients. There was no difference in prevalence and severity of post-stroke depression in relation to side of lesion. A test for receptive aphasia, the Token test, showed tha

Popular Abstract in Swedish Total parenteral nutrition (TPN) ges till patienter som av någon anledning inte kan tillgodogöra sig föda på normalt sätt via magtarmkanalen. TPN innebär att samtliga näringsämnen ges som intravenöst dropp. Av dessa näringsämnen intar fett en särställning. Det måste ges i form av små fettpartiklar utblandade i vatten till en emulsion. Det ställs stora krav på intravenöThis thesis evaluates alterations in lipid metabolism and Kupffer cell morphology seen during total parenteral nutrition in healthy rats. During infusion of lipid emulsions, cholesterol and phospholipids accumulated in non-high density lipoproteins, while high density lipoproteins were enriched in triglycerides. Triglycerides also accumulated in hepatic tissue, and the activity of hepatic lipase
