This thesis aims to analyse a time series containing the annual accumulation rate of minerogenic matter in the lake Kassjo?n. First there is a theoretical survey of some frequently used tools for the analysis of time series in the time domain and in the frequency domain. This survey is followed by a simulation study that illustrates how the theoretical tools work in practice. After this, the time series "toolbox" is used to analyse the time series from Kassjo?n (5701 data points).

This master thesis reviews advances in detection and diagnosis of static friction (stiction) in control valves. Control valves suffering from stiction results in oscillating control loops which in turn decreases both the process stability and reliability. Perstorp AB sees a necessity to automatically detect stiction in valves before the effects of the malfunctioning valves have become too severe. This thesis presents an introduction to maintenance, control loops and how stiction in valves can affect performance of control loops.A selection of methods presented in the literature are introduced and examined using normal operating data from the site in Perstorp. Common for all selected methods is their intuitive ideas and that they are based on normal operating data and minimum amount of process knowledge.

Internal communication is an important factor in organisations today. For many system development teams it?s critical that the communication works well. Without communication, success would be impossible. This study aims to highlight the effect communication has on the members of agile project teams.

Aim: The aim of this study was to explore the care providers' experiences in enabling communionship and solitude in daily living for elderly living in old age homes in a South African context. Method: This study was done using a qualitative analysing method, with empirical data obtained from nursing staff of elderly. The study was phenomenological which aims at deepen the understanding of human experiences as phenomenon. The data was collected by using a groupinterview which included five informants from an old age home in Pretoria. The analysis included two steps; Naive reading and structural analysis in order to transform the individual elucidations into an abstract which had no individual touch.

The objectives of this experimental study were to investigate if a strategic method to supply loose housed sows with large quantities of straw 2 days before expected farrowing and if the sow?s body condition had any effect on the occurrence of shoulder lesions 5 weeks after farrowing. Data came from a study conducted on four commercial piglet-producing farms in southwest Sweden between March and December 2009. At each farm one batch of sows was followed during two consecutive lactations. The sows were randomly assigned to two different treatment groups and the sows that remained in the batch during the second lactation switched treatment group.

The aim of this study is to learn about and demonstrate the process in which Försäkringskassan (The Swedish Social Insurance Agency) customizes texts and the texts linguistics influence on a potential beneficiary. I use three different questions to fulfill the purpose of the study. I examine what the manuals writers of Försäkringskassan use say about the issues of sentence length, addressing the beneficiaries and wording ? three language features that represent different perspectives within plain language research. Furthermore, I examine how decision texts are created and tailored for its beneficiary group and how the language in decisions is perceived by potential beneficiaries.

There is a need for productivities data and data for different types of machines for comminution of logging residues. The lack of data and studies on GROT comminution makes it difficult to evaluate different chains for handling of residue fuels and make system analyses.Four types of machines with three different working principles were compared at six studies during winter conditions. Three to eleven trials during 9.5 to 30.7 minutes were made on each machine. Samples from the produced material at each study were sieved to determine the size distribution of the comminuted material. Samples were also taken from the studies for determination of moisture content.

The purpose of this essay has been to examine the public`s view of the Swedish eldercare during 2006. This study uses discourse analysis as a research method, the reference material has been articles from the newspaper Dagens Nyheter. The aim of the research has been to find central themes, conflicts and consensus in the discourse of eldercare. The analysis resulted in four main subjects which were based on four main questions; the questions of responsibility and execution, the question of contents, and the question of where the eldercare should take place. The analysis of conflicts and relations of consensus in the discourse of eldercare resulted in two different main views; the traditional and a more modern.

This thesis examines a sample of Pitted Ware pottery from the Gotlandic site of Ajvide in regard to the spatial and temporal relationship of the shards. Ajvide Stone Age site have been extensively excavated over the past 25 years and the most recent analysis of pottery was carried out by Inger Österholm in 1987 and new analyses of the material are therefore greatly needed. Pottery from three sample areas was analysed in regard to their distribution, decoration, fragmentation, part of pot and quality of the goods. To analyse the material in a contextual way a multivariate statistical analysis called correspondence analysis was used. Two areas denominated ?dark areas?, which Österholm defined previously, as possible ritual sites, and one reference area with mixed material were chosen for the analysis.

This study is case study of political participation among the Kani tribe from Kuttichal grama panchayat in the Thiruvananthapuram district in Kerala, India. The study is based on the collected data of 117 people of the Kani tribe living in four different settlements: Pankavu, Mangode-Valippara, Chonampara and Kaithode. The aim of the study is to examine the impact on political participation by different factors, which is done by the use of the quantitative method of cross tables. The study confirms previous studies in its conclusion that high status individuals, defined in terms of education and economic standard, are the group of the highest political participation, when this is defined as being involved in political work and holding a party membership. On the local political scene however, where political participation consists of participation in local assemblies and voluntary work, the impact of the examined variables are very limited.

Introduction: Every year about 450 women in Sweden are diagnosed with cervical cancer, almost 200 die and thousands undergo surgery because of cell changes in the cervix. A HPV infection can lead to cervical cancer and therefor costs for the society. The implementation of a vaccination program against HPV is a way to avoid these costs. Aim: The study aimed to calculate the economic impact of the HPV- vaccination program for children in Sweden through a cost-benefit analysis. Method: In this analysis, status quo was compared with non-administration of the HPV-vaccine for the selected cohort of ten-years-old girls in Sweden.

There are about 700 000 dogs in Sweden. Roughly 70 % of the dogs are purebred and registered in the database at the Swedish Kennel Club (SKC). The database includes records of birth date, pedigree, offspring and results from e.g. veterinary examinations related to genetic health programs.Every year approximately 10% of the dogs die; most are euthanized by a veterinarian. Dog mortality data is stored as digital medical records at animal clinics and in insurance databases.Dog owners tend to register their puppy in the SKC, but they rarely report that the dog has passed away.

The purpose of this study is to improve our understanding of how immigrant children become included in some preschools. With immigrant children we meant those children who immigrated to Sweden. In order to achieve our purpose we have chosen to find out some educators' perceptions about inclusion and which strategies they use to include immigrant children.To realize the study purpose, we have chosen to use qualitative interviews as a method. We conducted interviews with sex educators who worked in two preschools. The empirical materials we got from the interviews formed the basis for our analysis.The analysis of our collected data was based on our theories and conceptions.

Semantiska webben är ett begrepp som handlar om att göra data tillgängligt på ett sätt som gör att datorer kan söka, tolka och sätta data i ett sammanhang. Då mycket av datalagring idag sker i relationsdatabaser behövs nya sätt att omvandla och lagra data för att det ska vara tillgängligt för den semantiska webben.Forskning som genomförts har visat att transformering av data från relationsdatabaser till RDF som är det format som gör data sökbart på semantiska webben är möjlig men det finns idag ingen standardisering för hur detta ska ske.För att data som transformeras ska få rätt betydelse i RDF så krävs ontologier som beskriver olika begrepps relationer. Nationella vägdatabasen (NVDB) är en relationsdatabas som hantera geospatiala data som används i olika geografiska informationssystem (GIS). För samarbetspartnern Triona var det intressant att beskriva hur denna typ av data kan omvandlas för att passa den semantiska webben.Syftet var att analysera hur man överför geospatiala data från en relationsdatabas till den semantiska webben. Målet med studien var att skapa en modell för hur man överför geospatiala data till i en relationsdatabas till en RDF-lagring och hur man skapar en ontologi som passar för NVDB?s data och datastruktur.En fallstudie genomfördes med dokumentstudier utifrån en inledande litteraturstudie.En ontologi skapades för det specifika fallet och utifrån detta skapades en modell för hur man överför geospatiala data från NVDB till RDF via programvaran TripleGeo.

The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.
