Gaspotentialen i en deponi, idag och i en framtid :
Deposited waste material degrades within a short period in anaerobic environments. The
methane gas that is formed provides a harmful contribute to the greenhouse effect, 23 times larger impact than carbon dioxide. It is therefore desirable to minimize the emissions of methane gas from landfills. This may be achieved by drain the landfill of gas.
In this thesis the amount of produced methane gas at the landfill at Örebro has been
calculated. Estimations have also been made of the amount of methane gas that might be
produced in the landfill in the future.
Att klassificera arkeologi: En komparativ studie av tre klassifikationssystem
The purpose of this Masters thesis is to compare classification codes and feature headings of three different universal classification schemes SAB, UDC and DDC, when classifying archaeological literature. The aim is to determine whether a subject analysis of a title generates similar feature headings in the three systems, and to find positive and negative things about each system from an archaeological point of view. The comparison and the analysis of the 22 chosen archaeological monographs showed that the subject analysis of the titles didnt always generate similar feature headings. This could depend on several things, for example different interpretations of the subject analysis of a document, less knowledge about the system and/or the subject, or the fact that its not the same classifier that creates the codes. The study also showed that the different classification systems did treat the subject archaeology a bit differently, and that its difficult to say that one of them is better for classifying archaeological literature.
Dietrich Bonhoeffers Teologi och Svenska kyrkans tro, bekännelse och lära. En jämförande studie
The aim of this paper is to compare the theology of Dietrich Bonhoeffer and the belief, confession and faith of the Swedish church in order to see similarity. The research questions that have been used are:1: What is the main feature of Dietrich Bonhoeffers theology?2. What are the main feature the belief, confession and faith of the Swedish church?3: Which are the similarities between the main feature of Dietrich Bonhoeffers theology and the main feature of Swedish church belief, confession and faith?The research method that has been used is comparative where the Dietrich Bonhoeffers theology is compared whit the Swedish church belief, confession and faith.
Skogsbränsleuttag vid förstagallring och dess påverkan på beståndsutveckling : simulering i Heureka med olika skötselprogram
Stands where pre commercial thinning has been ignored or inadequate often tend to have high stem density and low average diameter when they reach heights of thinning. In such stands, it can often be expensive to do a conventional pulpwood harvest as a first thinning. This study investigates the development of the stands and the economic outcome of forest fuel extraction, or a combined harvest as alternatives to the ordinary pulpwood harvest. Simulations in Heureka StandWise were performed for two thin and dense stands, which were constructed by data from the Swedish National Forest Inventory. The simulations show that the extraction of forest fuel in first thinning at an early stage can provide higher net revenue compared to conventional pulpwood harvest at the same time or later.

Media and the priming of stereotypes : Direct effect of news articles racial stereotypes on individuals judgements of people of foreign extraction.
The present research examined both automatic and controlled processes in newpapers ability of priming racial stereotypes via the portrayals of people of foreign extraction. The automatic process were examined through articles which; a) involved an illegal act or b) the act was not illegal but morally questionable. Swedish-born subject?s explicit opinions against foreign people were also measured through ?The Modern Racial Prejudice Scale?. In the experiment participants read four different articles which included; Swedish person/noncrime, foreign person/noncrime, Swedish person/crime and foreign person/crime.
Featurejournalistikens roll : En studie av regionala svenska dagstidningar
Syftet med denna uppsats är att undersöka hur svenska dagstidningsredaktioner förhåller sig till featurejournalistik i dag och vilken betydelse feature har för papperstidningens överlevnad. Undersökningen är uppdelad i en kvantitativ och en kvalitativ del. Vi har lagt fokus på fyra tidningar ? Katrineholms-kuriren, Norrköpings tidningar, Sydsvenska dagbladet och Göteborgs-posten. Som kvantitativ metod har vi räknat antalet texter med featurekaraktär i respektive tidning under en vecka i november 2009.
Filtrering av e-post ? Binär klassifikation med naiv Bayesiansk teknik
In this thesis we compare how different strategies in choosing attribute values affects junk mail filtering. We used two different variants of a naïve Bayesian junk mail filter. The first variant classified an e-mail by comparing it to a feature vector containing all attribute values that were found in junk mails in the part of the e-mail collection we used for training the filter. The second variant compared an e-mail to a feature vector that consisted of the attributes that was found in ten or more junk mails in the part of the e-mail collection we used for training the filter. We used an e-mail collection that consisted of 300 e-mails, 210 of these were junk mails and 90 were legitimate e-mails.
Något om regressionsanalys
En gren inom statistikteorin är den så kallade Regressionsanalysen där man studerar hur data från exempelvis ett stickprov kan anpassas till en graf. Skrivandet av denna uppsats har haft som syfte att studera några av de metoder som finns att tillgå vid bestämning av de ingående parametrarna i de enklare fallen av regression. Dessutom ges i de avslutande kapitlen exempel på den del inom regressionsanalysen som kallas Styckvis Linjär Regression eller Piecewise Linear Regression..
Konstruktion av current conveyors via makromodellering
A current conveyor is an active building block that can be used to implement most active and passive components. It differs from the operation amplifier in that it uses current instead of voltage. The current conveyor also has significantly higher voltage gain over a broader frequency range. To simplify the construction of analogue circuits and increase the construction efficiency it is desirable to use a top-down methodology. This means that the whole system is partitioned into a hierarchy of subsystems.
Evaluation of preanalytic methods in order to shorten the processing time before identification of fungal microorganisms by the MALDI-TOF MS
Identification of fungi is based on macroscopic observations of morphology and microscopic characteristics. These conventional methods are time-consuming and requires expert knowledge. For the past years Matrix-assisted laser desorption ionization-time of flight mass spectrometry has been used for routine bacterial identification in clinical laboratories but not yet in the same extension for fungi. In this study three preanalytic preparation methods for fungi were evaluated in order to shorten the processing time in routine laboratory performance.Clinically relevant strains (n=18) of molds and dermatophytes were cultivated on agar plates and prepared according to the different preparation methods for protein extraction. Each strain was analyzed in quadruplicate by the MALDI Biotyper and the database Filamentous Fungi Library 1.0.The results showed that the genus and species identification rates of the least time-consuming direct extraction method were 33% and 11% respectively.

Fördelar och nackdelar med utematematik : Lärares, föräldrars och elevers inställning till arbetsformen
Aligning parallell terms in a parallell corpus can be done by aligning all words and phrases in the corpus and then performing term extraction on the aligned set of word pairs. Alternatively, term extraction in the source and target text can be made separately and then the resulting term candidates can be aligned, forming aligned parallell terms. This thesis describes an implementation of a word aligner that is applied on extracted term candidates in both the source and the target texts. The term aligner uses statistical measures, the tool Giza++ and heuristics in the search for alignments. The evaluation reveals that the best results are obtained when the term alignment relies heavily on the Giza++ tool and Levenshtein heuristic..

Jämförande tidsstudie vid riskörning med kompakteringsskotare och traditionell ?lätt? modifierad skotare :
This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU.
The work was an assignment from Sydved Energy AB. The aim of the work was to compare the operational productivity between two kinds of forwarders for extraction of harvesting residues, one forwarder with a special compression device and one ordinary, slightly modified forwarder.
Two sites were studied for each forwarder. The study shows that the annual production was about 11,000 m3 higher for the traditional forwarder. The cost for the traditional forwarder was SEK 0.9 lower per m3.
