Sättningsberäkningar I kalkcementpelarförstärkningar. Jämförelse mellan mätningar och beräkningar enligt Allmän teknisk beskrivning
On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.

Integration eller återvändande? -Tillämpningen av tidsbegränsade uppehållstillstånd på bosnienkroatiska asylsökande i Sverige
Uppsatsen behandlar det motsägelsefulla flyktingmottagandet den bosnienkroatiska flyktinggruppen fick 1995, vilket resulterade i 5 års väntan på permanent uppehållstillstånd. De omfattades av både integration och återvändande samtidigt och fokus har lagts i uppsatsen på resultaten och upplevelse av integration idag. Till grund för uppsatsen ligger dessutom ett antal intervjuer med bosnienkroater och berörda tjänstemän..

Sample cradle prevents pre-analytic error on platelet counts but is not essential for hemoglobin measurement and prothrombin time
Introduction: It is recommended to place all the vacuum tubes directly on a sample cradle after vein puncture to prevent analytic error. This recommendation is not always easy to follow because the samples are taken by different professionals under different situations. The three most common analyses, platelets count, haemoglobin and prothrombin time were tested. Therefore, it was interesting to compare results from the three most common analyses with or without sample cradle, to evaluate the influence of this step on the result. Methods: Three analyses were preformed, using blood from 50 different persons. Each person gave two vacuum tubes, each contained 4.5mL of venous blood for the study.

Feedback och hälsa : en studie hos ett statligt verk
Today, many discussions are taking place through different platforms concerning the huge problem of ill health within modern society. Ill health tends to affect both children and adults. For the adult sector ill health may lead to doctor?s notification of illness in the short term and on the long term permanent disability benefit. In the mass media there are often articles published that point out the rising number of people with sick pay and people being given permanent disability benefit.

Modellering och styrning av flis till en sulfatkokare
At the Skoghall pappermill, sulphatepaper pulp is produced in a continuous digester originally from 1969. To be able to maintain a high level of production there is a need for a process with few disturbances. Variations in how well the wooden chips are packed in the digester is one form of disturbance. Today there are no available measurements on how well the chips are packed. Instead this is regarded as being constant.
Jämförelse av olika metoder att generera Bernoullifördelade slumptal givet deras summa
In this master?s thesis the problem of simulating conditional Bernoulli distributed stochastic variables, given the sum, is considered. Three simulation methods are considered, namely the acceptance/rejection technique, Bondesson?s method and the Markov chain Monte Carlo method.To compare the three methods the bias and the standard deviations of the simulated variables are evaluated. The results of the simulation study shows that the Markov chain Monte Carlo method is not the best method for this type of simulation.
