Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.

The purpose with this masters thesis was to model the scanner in a system for laser bathymetry. The model was then used to develop a controller for the scanner so a good search pattern was achieved. Two different types of models have been tested, a physical model and a Black Box model of Box Jenkins type. The physical model has been derived from Lagranges equations. Identification experiments have been used to compute the Black Box model and to find the unknown parameters in the physical model.

This master thesis is one part of a project, called ?StabSim?, with the purpose to develop a simulation model for the align and stabilisation system in main battle tank 122. The origin of this project is that it should be possible to make control analysis without risking any hardware. Besides that it will be easy to change components in order to investigate the behaviour of the system. The report includes modelling of tower and weapon mechanics and also the modelling of the synchronous motors, which control these.

I arbetet som har pågått i nu mer än ett år har vi behandlat sådant som förutsättningar för ett sådant projekt, intresset därav från studenter, skola och näringsliv samt rent tekniska aspekter kring konstruktionen av en farygsmodell dess elektroniska och mekaniska system samt hur en sådan modell kan användas i utbildningen av elever. Även sådant som funderingar kring studenternas säkerhet i samband med konstruktionen av och kring användandet av modellen behandlas i detta arbete. Vi har använt oss av metoden ?Grundande Teori? och har kommit fram till att Sjöfartshögskolan i Kalmar har exceptionella och helt unika förutsättningar för att starta ett projekt där man bedriver utbildning med bemannade modeller..

A manufacturing machine at the engineering company Sandvik Coromant has a positioning table which task is to move an item linearly. The positioning table has a linear motor capable of high velocity and acceleration. This makes it possible to achieve short cycle times and a more profitable production.The purpose of this thesis is to bring forward a new concept which is more adapted to the requirements of the positioning table. The reason is that the current positioning table provides an unnecessarily positioning accuracy of 0.01 mm, while the requirement for the positioning accuracy is just 0.1 mm. The goal is to reduce manufacturing and component costs.To develop a suitable solution an approach for the concept development process has been performed.

Several theoretical models of change exist concerning attachment, but an integrated view and knowledge of the role separate factors of change play for the individual is lacking. This phenomenon is hereby studied by semi-structured interviews of 20 persons. Change and factors of change are examined statistically with affectregulation as measure of attachment. The results show that these individuals´ changes are small and mostly towards secure attachment. Metacognition is related to greater change towards secure attachment.

The increasing oil prices during the last years have made it profitable to use cereal grains as a fuel. When compared with wood, cereals contain higher amounts of Cl, S and ash. The Cl and S content makes the gases from cereal combustion more corrosive than gases from wood combustion. The goal of this master thesis was to find out the variation of Cl, S and ash content for oat grain grown under different conditions. Oats was chosen because in Sweden it's considered as the cereal with the best fuel qualities.

The current study sought to examine if post-produced semantic memory cues are a good aid for memory recall. It also focused on remembering units with a meaning, instead of just remembering lists of words. In the current study a factual text was used where the participants were tasked with recalling as much information as possible either with the aid of cues (keywords written by the participants themselfs), computer with Internet or no aids at all. The results showed that keywords are significantly better for memory recall. The results were discussed in regards to modern models describing semantic memory.

This study was performed to investigate how the Japanese sect Aum Shinrikyo was legitimating its violence and killing acts. By analyzing the leader and members of the sect, and applying this information on two theoretical models, this paper tries to give an explanation of both single acts of violence and killing, and two terrorattacks.The result shows that Aum Shinrikyo was able to legitimate violence and killing acts through its ideology. In their opinion, cosmos was a place with several levels and everyone wanted to get as high as possible. Those who were killed by the sect would never be able to get to a higher level by living, since they would do too many bad actions. The murderers also got better karma since they helped the person to a better place.The legitimating of violence and killing acts in Aum Shinrikyo can be explained as a duty that is holy, which agrees with the theorists about religious terrorism..

SammanfattningJag har valt att problematisera varför vissa grupper och aktörer inte vill kalla sig för feminister och istället säger att de är för jämställdhet. Jag påstår därmed att på grund av det avståndstagandet har antifeminismen vuxit fram.Ordet feminist kopplas ofta samman med en vänsterpolitik, därför har jag valt att belysa högerns åsikter angående feminismen och jämställdhetsbegreppet. Jag har alltså utsett att undersöka en offentlig tyckare; Susanna Popova och det politiska fältet med Moderaterna och Kristdemokraterna. Orsaker till deras avståndstagande är feminismens starka koppling till vänsterpolitiken, att den är för generaliserande och fokuserande på endast kvinnan och hennes behov i samhället samt att feminismen endast tycks se till det kollektiva agerandet.Genom att ha belyst högersidans åsikter har jag visat på att jämställdhetsmålet inte behöver se likadant ut, liksom vägen till att uppnå jämställdhet i samhället.NyckelordAntifeminism, Feminism, Jämställdhet, Backlash, Popova, Moderaterna, KristdemokraternaAbstraktI have decided to problemize why people do not call them self feminists and instead say that they are ?for equality?.

Augmented reality is a technology thatcombines the perception and interaction ofvirtual objects with the real world. Itcan allow a user to visually see computergenerated models and informationinteracting with the real world through ahand held device such as a tabletcomputer. This opens up a range ofpossibilities, especially in theconstruction sector. A construction siteis permanently changing and the need forprecise and updated information iscrucial. The ability to enhance the realworld with virtual objects and informationmay make many plans printed on paperabsolete.This report describes how workers in theconstruction sector would benefit fromusing augmented reality on a tablet innumerous situations and the technologyneeded to achieve AR on a tablet.

Stigande kostnader för bränsle samt pressade elpriser gör att produktionen för ett kraftvärmeverk bundet till ett fjärrvärmenät måste optimeras. I denna rapport presenteras en ?Mixed integer linear programming? modell över Skogsbacka kraftvärmeverk, dess ackumulatortank, extrapannor och Lyckseles fjärrvärmenät tänkt att kortsiktigt optimera energiproduktionen. Kraftvärmeverket har en panneffekt på 50 MW och turbineffekt på 16 MW. Modellen tar hänsyn till fjärrvärmenätets framledningstemperatur och returtemperatur samt hur dessa parametrar påverkar kraftvärmeverkets drift samt hur de påverkar ackumulatortankens lager och laddning.

The purpose with this essay is to find out how active teachers think about integrate children with the diagnosis autism into the regular school. The method I have used to find out is a qualitative interview, where I have interviewed three teachers of various age and sex.A person with the diagnosis autism has problems with communication, social interaction and the ability to form a conception. Today, we do not know what causes autism, but we do know that it has to do with a neurological disorder. The word integrate means unite or join together as a wholeness. Many children who have a handicap may feel good to participate in a school where the other pupils do not have a handicap.

The consumption levels in Sweden, Denmark, Finland and Norway have been rising fo r the last decade. Even after the financial crisis of 2008, consumption levels continued their upward trend, regardless of the recession. The explanation seems to be, at least partly, that households tends to increase their debt ratio in order to continue the same standard of living as before in terms of consumption. It is clear, based of our results, that there is a connection between increased consumption and debt ratio for households. And the consequences of allowing loans to finance a sustained or increasing consumption may ultimately be difficult to manage.

English title: Part-time work among women in Sweden ? what influences choice of working hours? In the 1960s and 70s a large growth in part-time work amongst women in the Swedish labour market took place. A net inflow of workers into the labour market has been suggested as the main source. However, part-time work is still a common phenomenon among Swedish women; in 2004 almost 40% of all women worked part-time, and women are clearly dominating the part-time sector. A gradual changeover from house work to market work is hardly a valid explanation anymore.
