This report relate a concept study that consider a number of different proposals to improve the overcharging system in BAE Systems Ha?gglunds tracked vehicle series BvS10, to maintain sealevel power at extreme altitude.At high altitude the power losses beacuase of the air density that decreases, which results in less fuel can be burned. The decreasing of air density also gives rise to fatigue failure of the turbocharger unless power is reduced.The proposals shall be as required by BAE Systems Ha?gglunds economically sustainable and defensible from a packing perspective. That means the selected solution must have a reasonable price tag and at the same time a minimal impact on adjacent components.The basis for this thesis is based on benchmarking of both the auto industry as the flight industry, to find inspiration and tips for improvement.Some of the concepts have after gathering facts and calculations been excluded while other solutions has been considered as workable and thus interesting for BAE Systems Ha?gglunds.Initially the current turbochargingsystem was analyzed in order to determine the starting point and thus be able to fix the current problems surrounding high altitude driving.

The aim of the study is to investigate reasoning about variation in learning, made by Waldorf, Freinet- and Bifrost pedagogues. The focal points are how the pedagogues reason about variation in learning and why they want to use variation. It is a qualitative study, and it is done through interviews with one Waldorf pedagogue, one Freinet pedagogue and one Bifrost pedagogue. The conversation with each pedagogue is complemented by literature that describes and discusses each pedagogue?s specific teaching method. The results of the study are linked to different theories and reasoning by scientists and professors.

Data was analyzed via qualitative content analysis.FindingsMeeting and preparing relatives at the arrival at the ICU seemed valuable and led to safety and participation among relatives.

The Swedish Transport Agency has for a long time collected data on a monthly basis for different variables that are used to make predictions, short projections as well as longer projections. They have used SAS for producing statistical models in air transport. The model with the largest value of coefficient of determination is the method that has been used for a long time. The Swedish Transport Agency felt it was time for an evaluation of their models and methods of how projections is estimated, they would also explore the possibilities to use different, completely new models for forecasting air travel. This Bachelor thesis examines how the Holt-Winters method does compare with SARIMA, error terms such as RMSE, MAPE, R2, AIC and BIC  will be compared between the methods. The results which have been produced showing that there may be a risk that the Holt-Winters models adepts a bit too well in a few variables in which Holt-Winters method has been adapted.

The aim of this paper is to examine how teachers experience their possibilities to develop democratic teaching in high school and how they reflect upon their position of power within the teaching situation. Four professional high school teachers have been interviewed for the study. The theoretical perspective of the study is an intersectional view on power and a view on democratic teaching which is partly built on the high school curriculum, but mainly defined by deliberative conversations, anti-oppressive education and norm-critical education. The result of the study is focused on three themes, which were shown in the analysis of the interviews. These themes are: choices of teaching content,  authority of the teacher and democratic teaching.

Purpose: The purpose of this essay is to apply "Discount Dividend model" and "Discounted Cash Flow model" in reality during periods of economic boom alternatively recession.Method: A quantitative research method as well as secondary data and data collection method is used. This data consists of the company?s annual reports. Totally, 20 companies of different sizes under diverse economic conditions are involved in this data.Conclusion: After reviewing the companies? calculations, it is noted that the both models that are used reflect better stock-exchange rate during an economic recession..

In agricultural educations you learn to use different economic planning tools, as basis for decision. The purpose and goal of this work has been to find out if economic planning tools are used by the farmers in Sweden. We choose to do an investigation through personal interviews, and used an inquiry to get as equivalent answers as possible from the farmers. This work contains a literature study with relevant facts about the questions that is brought up in the inquiry. This study of literature explains shortly some different calculation methods and bases for decision. It also contains useable information that is important to know before an investment. The questions that are asked to the farmers have focused on the use of calculation methods and economical planning tools.

This composition deals with questions concerning the ongoing construction of gender among personnel in different project for young girls and young boys ( ages 14): its conditions and meanings and how personnel form and mediate gender experience. The aim of this essay is to investigate how gender is made in everyday practise in three projects which address to either young girls or young boys, and to examine how the formation of gender interplays between conceptions among personnel and the practise in the projects. Central questions are: How describes the practical work and the needs of girls and boys in the project? And does the gender-segregated work justified in the projects? Qualitative methods are used to answer these questions. We made qualitative interviews among personnel from three projects, Ellen, Allan and DISA.

Background: Obesity surgery is the only technique that has proved to have a long-lasting effect on weight loss. Operation is not a solution but rather a lifelong involvement for the person. To loose a lot of weight means a big adjustment for both body and mind and the operated person may need support, advice, information and encouragement. Aim: The aim was to describe how a person, operated for obesity, can be supported in order to reach improved health pre- and postoperative. Method: A systematic literature study was made which resulted in 18 scientific articles that have been reviewed.

The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.

Before the European construction standards were introduced in January 2011, it was mainly themethod in BBK04 that was used for calculating punching capacity in concrete structures, and in lesscommon cases the method in BHB. The method of BBK04 is easy to use and have had the samestructure since the first was published in 1979. The Concrete handbook method (BHB) where usuallyonly used when a higher punching capacity was needed and the cross-sectional height where fixed,calculations using this method entails more work, but will in return usually give a higher capacity. Italso allows the use of shear reinforcement to increase the cross-section capacity. The method ofcalculating punching shear in EC2 differs largely from the methods of BBK04 and BHB.

During the past twenty years the immigration to Sweden has changed significantly. Earlier immigration mainly focused at filling the vacancies in the Swedish industry, today immigrants primarily come to Sweden as Refugees. This change of immigration combined with the restructuring of the Swedish industrial sector has resulted in great a deterioration of the chances for immigrants to gain entry to the Swedish labor market.This study aims at examining how the cooperation between authorities in the municipal of Hörby in Sweden fosters integration. The study primarily examines how the cooperation between authorities in a integration project can contribute to a better integration to the labor market.Through a qualitative study, five persons who occupy important roles in the project have been interviewed. The results of these interviews have been complemented by internal documents as well as extern material to validate the results.The most important findings that have been revealed are the importance of language in the process of gaining entrance to the Swedish labor market.
