This report treats two assignments that concerns the biofuel furnace at Billerud Skärblacka AB and how these assignments were solved. The assignments were: reducing the number of CO-spikes and tuning the overfire air control loop. To reduce the number of CO-spikes the possibility that skewness in mass distribution affects the number of CO-spikes were study. The skewnwss of mass distribution was controled and adjusted with two experiments. The conclusion that was made is that the skewness of mass distribution were not sufficient enough to affect the number of CO-spikes.

This report evaluates whether normal approximation or resampling is to prefer for estimating the distribution of the sample mean and functions of the sample mean. The evaluation relies on simulation studies. The observations of the sample are allowed to be differently distributed. In the case of sample means they are also allowed to be dependent.For sample means the two approximations behaves very similar. The most important component whether we have a good or a bad approximation is how good the approximations catch the variance of the true distribution.

Syftet med denna uppsats är att undersöka vilket användningsområde journalister, som är anknutna till en redaktion, har att använda sig av bloggar och dess möjligheter. Vi vill undersöka bloggen som fenomen och då i synnerhet varför journalisten väljer att använda sig av denna alternativa medieproduktion, trots att han har möjlighet att genom sin redaktion kunna uttrycka sig och bli publicerad för en allmänhet som lyssnar till honom/henne. Vi kommer med hjälp av intervjuer, gjorda via mail, försöka att klargöra hur bloggen används av journalister och till vår hjälp kommer vi att använda Jürgen Habermas teori om offentlighet så som han har förklarat det i sin bok Borgerlig offentlighet.Frågeställningen i uppsatsen är:· Hur ser journalisten på bloggen i avseende på det offentliga och det privata?· Vilket urval gör journalisten då han/hon skriver i sin blogg?· Hur kan journalisten använda sig av bloggen?Undersökningen grundar sig i två stycken mailintervjuer med journalister som själva bloggar. Dessa två är Anders Linder, ledarskribent på Svenska Dagbladet, som bloggar under Svenska dagbladets redaktionella flagg och Andreas Ekström, journalist på Sydsvenskan, som skriver i ett mer privat rum.
