This master thesis work was done by two students at Machine Design at KTH for Lesjöfors Stockholmsfjäder AB. The task was to develop a calculation program for gas springs. The program is going to ease the selection of gas springs for a given case of a lid that should be opened. The program is going to be used internal by sales people at Lesjöfors AB in Sweden and internationally. The program is therefore written in English.The program was developed in Microsoft Visual C# 2008 Express Edition.

Counterinsurgency (COIN) has made a comeback during the early 21-century since the majority of western countries have been involved in peace enforcement in the middle-east. Since its comeback the concept of COIN have been wildly debated but also undergone some chances since its early days, today the majority of COIN theories claims that the local population is the key to winning a COIN campaign. If you gain their trust the insurgency will lose their support and recruiting base, this is the reason why collateral damage resulting in in civilian deaths are contra-productive, it creates more insurgents. This is the incitement to further examine how civilian deaths occur and can be avoided during COIN campaigns. This essay studies the American COIN campaign in Iraq between 2004 and 2009 and aims to investigate whether there is a trilemma-like relationship between the key goals of COIN: protecting civilians, protecting one?s own forces and neutralizing the enemy.

At the time of the study, there is no law to prevent an employer from doing criminal background checks. Employers for School and childcare have to do criminal background checks before hiring but the background checks have increased significantly in other industries as well. The aim of this thesis is to analyze and explain what interest employers may have in jobseekers history and how it can affect people?s privacy. To do this I have used right dogmatic approach combined with four interviews with different employers to get their perspective on the subject.

Studiens syfte var att undersöka om patienter upplever att de fått tillräckligt med information inför sövning vid operation. Information är en viktig del i omvårdnaden, för att skapa en trygghet hos patienten. Många patienter upplever oro inför sövningen, vilket kan minska om patienterna är välinformerade. Studien bedrevs med en kvantitativ ansats som en enkätstudie på sju avdelningar på Karolinska sjukhuset, Huddinge. Frågeformuläret konstruerades av författarna inför studien och testades i en pilotstudie.

The Energy Market Inspectorate is implementing a new tariff regulation in Sweden. A small part of the new regulation concerns effectible operation costs and originally they where intended to be calculated using a modification of equivalent comparison standards, in Swedish Ekm. This thesis is intended to analyze if Fortums grid in Stockholm could be described correctly, using equivalent comparison standards. In Ekm every part of the distribution grid is designated a weighting in relation to 1 km 0.4kV over head line. These Ekm-measurements are intended to simplify comparison between different grid areas with different structure and geographical conditions.

This thesis treats the extended Swedish rules regarding deduction limitations on interest. The purpose for this thesis is to investigate whether the interest deduction limitation rules have potential to protect the Swedish tax base. The thesis also assesses whether the options presented how the extended rules could look liked had been better to protect the Swedish tax base. Furthermore thin capitalizations rules have been evaluated if this is a better method to protect the Swedish tax base.In 2009 the Swedish deduction limitations rules on interest came in to force to protect the Swedish tax base. Despite these rules companies was still able to avoid Swedish tax and therefore threatened the Swedish tax base.

Att sövas inför en operation innebär att lämna över kontrollen av sina livsfunktioner och är en situation många patienter känner oro inför. För att kunna utveckla anestesisjuksköterskans preoperativa omhändertagande är kunskap om patienters upplevelser av omhändertagandet nödvändigt. Dessa upplevelser kommer att studeras med utgångspunkt i en teoretisk begreppsmodell om personcentrerad vård.Syfte: Att beskriva patienters upplevelse av det preoperativa omhändertagandet inför anestesi.Metod: Kvalitativa semi-strukturerade intervjuer kommer att genomföras med ett tiotal personer som i slutenvården genomgått en operation i generell anestesi. Intervjuerna kommer att analyseras med kvalitativ innehållsanalys. För att testa metod och forskningsplan genomfördes en pilotstudie där två forskningspersoner som nyligen genomgått en operation i generell anestesi intervjuades.

By using pollen analysis, 14C-dating and historical sources, I studied the history of vegetation and land use at an abandoned forest settlement near the Lade summer farms in the parish of Mora, Dalama. The aim of this paper is to investigate the agricultural establishment and development, the effects of this on forest vegetation, and the origin and development of summer farming. The analysis of pollen in a peat core revealed that a settlement was established at Lade around 1000 AD. Cereal cultivation, hay-making on the mire and extensive forest grazing were intro-duced as a complete agricultural system. Pollen analysis and the presence of ancient fields suggests that cultivation took place on permanent fields. Barley was the main crop, but rye and hops/hemp were also grown at the settlement.

Bakgrund: ?rligen opereras cirka 400 000 patienter inom slutenv?rden i Sverige. Det finns forskning som visar upplevelsen av att v?nta p? en elektiv operation, dock saknas det forskning om hur patienterna upplever v?ntan p? en akut bukoperation. Specialistsjuksk?terskan beh?ver kunskap om och f?rst?else f?r hur patienterna upplever sin v?ntan p? en akut bukoperation f?r att kunna bem?ta patienten och ge trygghet.

To make wave power more competitive on the market Uppsala University leads projects that examine how to accomplish better efficiency in the production. One of these projects is described in this report and examines whether it is possible to make the production of dovetails more efficient by using an industry robot of type ABB IRB6000 S3 M91. This project is using an already presented working method, from a previous project, which involves that the robot picks up the dovetail and moves against fixed cutting machines where the dovetail will be drilled, threaded and milled. Drilling and threading are the sub operations that will be examined in this project where experiments are made with the presented working method and with equipment from Uppsala University.Experiments show whether it is possible to drill the holes in the dovetail within specifications by using the specific robot and the presented working method. The threading operation is examined theoretically if it is possible to accomplish by using the same working method.

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

Jämtkraft AB has recently modernized its hydropower station at Hissmofors by replacing four older worn out units with two new units. The generators uses a concept with sliding stator feet to deal with the thermal movements that occur in the stator during operation when the unit is operating intermittently. At other sites, this method revealed shortcomings in the reliability. This has made Jämtkraft AB feel uncertainty about its function and therefore want to investigate it during an early stage. The generators have a built-in monitoring system for the sliding stator feet and by using data from there the function of the sliding stator feet has been investigated. The study focused on how the different stator feet move relative to each other and how the eccentricity and deviation from roundness changed during operation. The results show that there are several indications that the function of the sliding stator feet is not satisfactory.

The purpose of this project is to get a fully functional, automatic steering system and a variable breaking system with an emergency breaking function to an off road vehicle. This off road vehicle is supposed to work as an aid in military situations. A team of two, Sebastian Attervall and Nichlas Gustafsson, got an order from Jonas Nyårds and the PreeRunners Project to construct a steering system that could manoeuvre an off road vehicle without any human involvement. To make this possible the vehicle would be guided by onboard sensors, cameras and computers. The team where also assigned to construct an automatic breaking system, there also no human would be involved.

A new build in the Swedish nuclear power system would entail increased re-quirements for the proposed repository, which is adapted after the reactors of today. With a fast reactor, capable of burning nuclear waste, operating in parallel with the light water reactors, the increased requirements on the repository could be reduced.In this thesis, simulations of a light water reactor and a fast reactor have been performed by using the Monte Carlo code Serpent to investigate the changes in the fuel inventory. The light water reactor in the study is a boiling water reactor and the fast reactor of the type sodium-cooled fast reactor and they have been used for three different operation scenarios.By studying the fuel composition and the results from the simulations of the three scenarios conclusions can be drawn. Conclusions regarding the change of the fuel inventory and decay heat in Clab as well as the interim storage facility and in the repository. Depending on the operation alternative the changes dif-fered significantly and especially regarding the mass of burned actinides for different fuels in the fast reactor.The lowest increase of fuel assemblies was meet when using 50 years old fuel with 20MWd/kg U burnout and 2,0 % enrichment for start up of the fast reactor and 30 years old fuel assemblies with 50MWd/kg U burnout and 4,7 % enrichment for the further operation of the reactor.The increase of the number of fuel assemblies was 3174, which is equivalent to 641tons of heavy metal.
