Forestry affects most of the forest-covered land in Sweden. In the landscape, the most common stream type is headwaters, which are important sites for many processes and organisms in both the terrestrial and the aquatic ecosystems. The aim of this study was to investigate how the abundance of benthic invertebrate functional feeding groups in headwater streams develops after clear-cutting and if it also is possible to detect a change in the composition of feeding groups. The study also attempts to determine what factors have an effect on temporal changes in abundance of these groups. For the study, 11 sites in northern Sweden were sampled for benthic invertebrates using a Surber-sampler, and for each site canopy-cover and pH was obtained.

Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.

The Swedish regions are new phenomena, from the start from the new regionalism which started in the 1980´s. The purpose of the thesis is to analyze Region Skåne and Västra Götalandsregionen to come to a conclusion which model of region they are and want to be by using theories of regional identity and identity of politics and see similarities and differences. My research question is: Which of cultural, administrative and functional region are Region Skåne and Västra Götaland striving to construct?   The methods I have used are qualitative text- and content analysis to analyze the regions, by using theories about regional identity and identity of politics. Furthermore, I am using some statistic from SOM-institutet to analyze the regional identity in the regions.   The result show that Region Skåne is constructing a cultural region, because of their strong regional identity and that the politicians are using identity of politics to combine the citizens.

Den här uppsatsen behandlar skillnaderna i attityd till Functional food mellan Sverige och Danmark. Syftet är att utreda, med hjälp av adoptionsteorier, segmenteringsteorier och teorier om kulturella skillnader, de olikheter som finns mellan de danska och svenska konsumenternas attityder och inställningar till Functional food och hälsomat. Vidare tänker vi utreda varför dessa skillnader existerar. Produkten som fokus läggs på är en cereal bar som tillverkas av ett internationellt företag. Den marknadsförs redan som extra nyttig på andra marknader och företaget hoppas kunna lansera produkten på liknande sätt i Sverige och Danmark.

The aim with my work was to gain a deeper understanding of some adult adopted children?s experiences and reflections about which role parent ship plays for the adopted child?s development of identity. Following questions have been in focus: What does a working parent ship imply, seen from the perspective of adopted child? In which way can the development of identity for the adopted child be supported by a functional parent ship? Semi-structured interviews were carried out with the two following themes: Support and confirmation. The sample consisted of five foreign-adopted between the age of 18 and 37 years.

Ombord på fartyg är det inte önskvärt att få strömavbrott, en så kallad blackout.Examensarbetet har undersökt i vilken utsträckning det är möjligt att utföra jämförande ochförebyggande studier med haverirapporter från europeiska flaggstater som underlag. Detta föratt undersöka återkommande brister, på fartyg eller i arbetet ombord som har orsakatblackout. Dessutom har även möjligheterna till att kunna kategorisera fallen undersökts.Kategorierna var tekniskt fel, operativt fel och organisationsfel. I ungefär häften av fallen gickdet inte att kategorisera en blackout till ett fel, eftersom det annars var en kombination av fel.Däremot finns återkommande fel där händelseförloppen är väldigt lika. Till exempel var hetaytor inte korrekt isolerade, vilket resulterade i brand vid bränsleläckage.Undersökningen visar att det finns en bristfällig symmetri i rapporteringen av haveri medavseende på språk, struktur, omfattning och publiceringsform.

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

The aim of this master thesis was to create a dynamic model for the processes in a solid fuel boiler of the moving grate type. Another aim with the model was to keep it as simple as possible but still able to catch the dynamics of the processes in the bedplate of the boiler. The creation of the model had its origin from drying and combustion equations used in earlier modeling work of boilers. The represented model has been used to simulate different kinds of disturbances in a boiler and different ways to control the boiler. These tests show that controlling a number of parameters in the bed of the boiler is an effective way to keep the grate stable during disturbances.

Nuclear power plants existences have been well debated since the 70s (Swedish radiation safety authority, 2014). Accidents, risk and presence connected to nuclear power plants have been part of many studies around the world. Recent studies have shown a connection between prices of houses and the distance and presence of nuclear power plant in a surronding area of the house. This paper uses Hedonic price modelling to investigate the willingness to pay for an increased distance to the Swedish nuclear power plant, Forsmark. For the dependent variable selling price was used and the independent variables were number of rooms, living area, other area, lot size, selling year, building year and distance to Forsmark.

The aim is to develop a new decision-making model for credit-loans. The model will be specific for credit applicants of the OKQ8 bank, becauseit is based on data of earlier applicants of credit from the client (the bank). The final model is, in effect, functional enough to use informationabout a new applicant as input, and predict the outcome to either the good risk group or the bad risk group based on the applicant?s properties.The prediction may then lay the foundation for the decision to grant or deny credit loan.Because of the skewed distribution in the response variable, different sampling techniques are evaluated. These include oversampling with SMOTE, random undersampling and pure oversampling in the form of scalar weighting of the minority class.

This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.

The functionalism started in southern Europe after world war one and got its breakthrough in Sweden with the Stockholm Exhibition in 1930. Poverty caused many people living in overcrowded conditions which the functionalists wanted to change by using less expensive materials and giving healthier living conditions to the people. The industrialization brought new materials and working methods which made this possible. The Swedish functional style is recognised by its light plaster facing and nearly horizontal roofs. Also the garden design of that time was influenced by the functionalistic ideas. The garden was now introduced as a pleasure garden for not only the rich but for everyone.

The purpose of the present study was to examine effects of driver, vehicle, and environment characteristics on Collision Warning System (CWS) design. One hypothesis was made that the capability of collision avoidance would not be same among a driver, vehicle, and environment group with different characteristics. Accident analysis and quantitative analysis was used to examine this hypothesis in terms of ?risk? and ?safety margin? respectively. Rear-end collision had a stronger focus in the present study.

Background: An effective management of the healthcare's organization on one disaster site is considered as a condition in order to decrease damages and suffering at them as been hit of an accident. In KAMEDO-reports is described true accidents, how among other thing organizational parts been implemented and evaluations of which importance different decisions had. Aim: The aim of the study was to examine KAMEDO-reports concerning prehospital medical management on disaster sites. Method: Eight KAMEDO-reports was examined with focus on organization and management. Results: Four areas in which all could be influenced by the healthcare personnel in leading position was described: Management and Co-operation, Load and Go - Stay and Play, Priority and Triage.

Functional Magnetic Resonance Imaging, fMRI, can be used for analyzing brain activity in subjects performing language tasks. The purpose of this study was to develop aphasia-friendly information adjusted to aphasic subjects participating in fMRI studies. The objectives were to investigate if adjusted information was important for the ability to perform language tasks and if the information could be used for different types of aphasia.Sixteen aphasic subjects participated in the study, six of these underwent fMRI. The participants varied in grade and type of aphasia. They had Swedish as their native language and were aged between 26 and 89, mean 57.
