Purpose: The purpose of this paper is to investigate whether there is a correlation between the actuarial assumptions, of listed groups in Large Cap on the Nasdaq Stockholm, equity ratio and their pensionplans funding status.Method: The study is based on a quantitative research method, where the analysis of annual reports takes place. The quantitative research method has enabled the paper to perform related analyzes and comparisons of means between groups, for listed companies equity ratio and pension obligation, and the relation to its actuarial assumptions. Correlation measurements are made using a non-parametric method, Spearman's rho, then further tested using one-sided hypotheses t-test.Theory: The backbone of the thesis is presented using two theories, earnings management and the principal-agent theory. These theories are intertwined with the previous researches, which also dealt with the essay topic of earnings management in previous years and in other countries.Empirical: Correlation analyzes between the studied actuarial assumptions and corporate groups solidity and pension financial status is presentedusing tables and charts. These are further analyzed using hypothesis tests and scatterplots.Conclusion: All tests resulted in very weak correlation between the different variables and can there for not be classified as significant.
Konstruktion av värmespridare med grafit för flygelektronik
This master thesis was carried out for Saab Avitronics, a business unit of Saab ABactive in electronic systems for military aircrafts. Reliability and weight are of crucialimportance in this environment. To improve reliability and lower the weight graphitemay be used for electronics cooling. Graphite is an anisotropic material and hasthereof high thermal conductivity in two directions (in-plane) and a relatively lowconductivity in the third direction (through thickness).The purpose of this thesis was to investigate if graphite is an adequate thermalconductor to use in PCB carriers. The carriers support and cool the PCB by divertingthe heat dissipation from the PCB components to the edge.
Tanklock med förbättrat grepp
This degree project was conducted in collaboration with Husqvarna AB, the headquartersof which are located in Jönköping. The aim was to further develop the filler cap found onmore or less the whole of the company?s range of chain saws, in order to make it moreuser friendly.The present filler cap is not easy to open and close, especially when wearing gloves, andunder difficult conditions, which creates problems and prolongs filling time.On the basis of market surveys, different prototypes and tests, we have created anergonomically improved cap of a new shape, which can be moved in the axial direction,thus making filling easier..
Beslutsstödsystem för munslemhinneförändringar
This thesis has been carried out in collaboration with two students at the Department of Dental Medicine at Karolinska Institutet in Stockholm, Sweden. The aim of this project was to construct a computerized decision support system to facilitate diagnosis of changes in the Oral Mucosa using information collected by the above mentioned students. A program which poses specic questions to the user was constructed with the Java programming language. Depending on how these questions were answered, one or more possible diagnoses were presented by the program. In order to conclude whether or not this program was of any use in terms of time savings, a series of tests were run and timed both when using the program and when not.
Allsidig rörelsekompetens hos barn och ungdomar : En kartläggning av skolelevers funktionella motorik
Gross motor skills among Swedish pupils. An overview of functional motor abilities among Swedish children and adolescents.IntroductionPhysical Education (PE) teachers in Sweden have noticed that pupils are getting worse in their ability to manage gross motor skills and in their aerobic practice. The gross motor skills and coordinative skills are the solid ground for sports and other health activities. If not developing their gross motor skill children tends to avoid taking part in games and sports. The benefits of sports and outdoor activities such as social and health benefits can therefore be missed.
Turnover Intention. Orsaksfaktorer för intention till egen uppsägning inom vården och snabbmatbranschen.
Genom att studera relationen mellan intention till uppsägning och upplevd arbetstillfredsställelse, organisationsengagemang och kommunikation söktes stöd för studien syfte, det vill säga att identifiera vilka faktorer som ligger till grund för intention till uppsägning inom vården och snabbmatbranschen. Datainsamling gjordes med hjälp av en webbenkät som skickades till deltagarna(N=48), vilka härrörde från ett äldreboende och en snabbmatskedja i Blekinge. Genom Spearmans korrelationstest och Mann-Whitney U-test analyserades den insamlade data. Resultatet visade stöd för två av studiens hypoteser gällande korrelation mellan arbetstillfredssällelse, organisationsengagemang och intention till uppsägning. Resultatet gav även delvis stöd till två av studiens hypotes vad gäller negativa korrelationer mellan anställdas arbetstider och avsaknaden av kompetensutveckling inom organisationen och avsikten att stanna kvar på sin nuvarande arbetsplats, samt signifikanta skillnader för hur anställda inom vården och snabbmatskedjan upplever organisationsengagemang och relation till ledningen.
Regelstyrning eller självreglering - skiljer sig revisorns bedömning åt?
The purpose of this essay is to examine if the judgments of accountants differ, in different cases, between the old and the new law. The method we used to investigate the differences was a combination of experimental and non experimental. Our analysis is based on a survey investigation with ten cases. These cases are produced from a model in which the accountant tests his independence. The survey was sent by mail to about a hundred accountants.

SAAB Automobile ABis a car manufacturer within General Motors corporate group. SAABAutomobile ABhas a big part of the responsibility for the brake development in the corporategroup. The car industry is facing harder environmental requirements, which influence the brakedevelopment. The focus is to develop brakes with low drag and sustained brake feeling andperformance. Important characters for the brake caliper are high stiffness and low weight, highstiffness results in high performance and low weight is important because it is unsprung mass.This thesis investigates the possibility to improve the performance of the brake caliper for aGMproject.
Analys och dimensionering av robusta kilspårsförband
This master thesis comprises analysis and dimensioning of a keyed joint between a generator axis and a hub with aid from the FEM-software ANSYS Workbench 13.0.The generator axis is a part of a hydroelectric power station that generates electricity with a reactions turbine, a Kaplan turbine. The existing keyway consists of one parallel key with the width 90 mm and height 45 mm. Due to a planned increase of the power of the generated power with 32 % a design study was needed to see if the keyed joint would be suitable for the extra force. Because of the fact that the axis diameter is bigger than the standards covers/recommends a the keyway had to be re-dimensioned. In an earlier assignment from Skellefteå Kraft AB to Sweco Energuide the keyway was planned to be properly dimensioned, but no final solution was approved.During this master thesis a number of different numerical tests were made.

Utveckling av provmetodik för HVAC på lastbil : Klimatprovning i klimatvindtunneln CD7
The issue about how Scania shall perform HVAC tests in the climatic wind tunnel CD7, which Scania is about to complete by year 2013, has resulted in four test methods for truck HVAC and also a test method structure. The test methods have been chosen to focus on sun, snow and rain simulations. These are adapted and developed according to what should be tested and to what can be tested in CD7, which has been the object. With CD7 different climates can be simulated in a controlled environment for complete truck level, from desert with high sun load to arctic cold and snow.The test methods represents a basis to start from, for designers and test engineers which make the testing more repetitive as well as time eventually can be saved. Before the test methods can be applied they must be verified as they are based on theoretical and empirical assumptions.

Phosphorus in agricultural soils around the Baltic Sea : comparisons of different laboratory methods as indices for phosphorus leaching to waters
Eutrophication of the Baltic Sea is a serious problem. A major contributing factor is diffuse losses of phosphorus (P) from agricultural land in surrounding countries. In order to estimate P losses, environmental monitoring of small agriculture-dominated catchments is being carried out in most of these countries. Evaluation of the risk of P leaching to waters is usually based on chemical tests originally developed to quantify the amount of soil P available for plant production. The tests are performed in different ways in the different countries and a number of different extraction agents are in use.
