A multivariate cross-sectional model is used in this thesis to proxy for expected earnings and to estimate return on equity for 214 companies over the period 2009-2013, using Swedish data. The model, which has never been tested on Swedish data before, is first confirmed to function as a forecasting model for expected return. Furthermore, the model is evaluated through a comparison with two univariate models based on the assumption that return on equity follows a mean reversion process. Forecast accuracy is calculated as the difference of estimated returns and actual returns. The results show that the univariate models' forecasts are superior to the multivariate model's..

In offshore oil production FMC Subsea systems use a product called cap. The cap´s mainly task is to protect hubface and seal areas on inboard hub against dirt, corrosion and mechanical damage under installation of a subsea system. A new model of a cap has been designed and analysed using finite element method. The model is called KC3-12 and has a new function, emergency release, which is a backup method for the ROV (remote operated vehicle) to release the cap from the hubface when it is placed under water. The cap KC3-12 was found to fulfil the criteria under the test load pressure, according to ASME VIII, div2.

During 2007 the City of Stockholm installed five grid connected photovoltaic systems. The aim of this master thesis is to quantify the amount of produced energy and recommend routines to collect and analyse production data, to make production data accessible by the public and to gain experience for future installations.The total amount of produced energy until March 2009 is 227 000 kWh, with an annual rate of 150 000 kWh. The expected annual rate was 148 000 kWh.All system owners are positive about their plants and see economical benefits in scaling up such systems.The installations need very little attendance and maintenance, however it is recommended that an alarm function is installed for automatic feedback in case of a system failure. All future systems should be inspected during full operation to determine if the actual capacity is matching the installed capacity..

Syftet med studien var att utvärdera vad tidigare klienter på Lenagården HVB, ett behandlingshem för vuxna med psykiska problem, upplevde som värdefullt, respektive vad de upplevde som negativt eller saknade i sin behandling. Utvärderingsfrågorna utgick från Lenagårdens programteori samt aspekter som tidigare forskning kring institutionsbehandling pekat ut som viktiga för framgångsrik behandling. Data samlades in via kvalitativa intervjuer med fyra tidigare klienter. Systemteorin har använts som utgångspunkt för resultaatanalysen.Utvärderingen visar bland annat att gott bemötande i termer av vänlighet och respekt samt personalens kompetens ansågs vara värdefulla faktorer i behandlingen. Själva terapin och behandlingsmetoden ansågs av samtliga intervjupersoner vara givande.

The web sites of Swedish public libraries display a high level of heterogeneity when it comes to design and graphical user interface. The thesis is based on the opinion that the visuals of a public library web site have implications for the user as well as for the library. The design of the graphical user interface influences the attention of the user and his/her ability to absorb information. Furthermore, there is a connection between the visuals and the users opinion about the credibility of the content of the web site, as well as of the organisation itself. The research question is: Which factors may have an impact on the design of the graphical user interfaces of a public library web site? The purpose is to create an understanding for these factors and emphasize them.

Homework is and has always been a part of school work. It may take a lot of time from the pupils? leisure. Despite this, you cannot find anything written about homework in the curriculum. How can this be? Is homework necessary and what is its function?The purpose of this study is to find out how a few teachers in primary school reason about homework.  What are their attitudes towards homework and what functions do they see?To get an answer to this I studied literature and research reports, and did four qualitative interviews with teachers who teach grades 1-6.The results show that all the teachers give homework to their pupils, but their opinions about homework differ.

Den här rapporten handlar om Individuella utvecklingsplaner (IUP). Från 1/1-06 gäller en förordning om att alla barn i grundskolan, särskolan, sameskolan och specialskolan ska ha IUP. Syftet med rapporten är att undersöka vilken information lärare och elever fått om IUP, men också ta reda på deras inställning till och uppfattning om IUP.För att få reda på detta har jag intervjuat fem lärare och fem elever. Lärarna har mellan 3-20 års erfarenhet av skolarbete. Eleverna går i skolår 1-6.

By limiting our horse?s freedom of movement, we restrict their opportunity to forage, which is one of their most important needs. If their need of forage is not fulfilled it can lead to frustration, which might manifest itself in abnormal behaviour, like the oral stereotypies for example crib-biting. It is a held belief that the horse swallows air while crib-biting, which they don?t, and that swallowed air causes colic, and the belief that other horses can copy the behaviour, leads to the use of many methods to prevent the behaviour.

At Kungliga Biblioteket in Stockholm you can find over 40 000 letters sent to Selma Lagerlöf. Many of her readers wrote and asked for her help, and the letters show that she helped a lot of people with money as well as with writing advice. People from all over the world asked her for money to be able to study, to finish their written works, or just to get through the day. Others want her to read their texts and poems, because they wish to hear her opinion or wonder if she can put in a good word for them at some publisher. This essay illuminates the question why so many people had this confidence in Selma Lagerlöf.

This thesis is made on behalf of SCA's Forestry Division and is a comparison of two bucking simulation tools: Aptan (manufactured by Skogforsk) and Best/upr (from Berget Systemdesign). The data is based on 32 stands from SCA's forests in Norrbotten and Västerbotten. The objective is to compare the simulations created by the tools with the harvested volumes from those stands. Three variables are needed for the bucking simulation; these are the diameter distribution (at breast height), the relationship function between diameter and height, and the taper coefficients. The volumes of five different assortments from the stands are compared.

This report is about the issue with decreasing production rate mainly caused by failuresrelated to the multiswitch. The multiswitch is a machine at Gefleortens Mejeriföreningwhich has the function of distributing milk cartons from one incoming track into fiveoutgoing tracks. Milk cartons who gets stuck and there by causes the production to stop,is the mainly problem with this constructionThe purpose with this report is to understand the causing factors and make suggestions which can help solving these factors. By analyzing the machine during production, having contact with different suppliers, searching internet for information, 3d-cad drawings and the complementary with personal experiences, this machine has  been evaluated and as a result of this new problem has come to be known.The discovered problems was analyzed and resulted in new suggestions for alternative options. Later the most functional results was chosen and put as a suggestion for the new model.A new machine built with the suggestions from this report assures to be well adapted to the environment at Gefleortens Mejeriföreing and the problems it causes..

Warehouses are a key aspect of modern supply chains and play a vital role in the success or failure of businesses today. Figures from the USA indicate that the capital- and operating costs of warehouses represent about 22 % of a company?s logistics costs while figures from Europe indicate 25 % (Baker & Canessa, 2009). Because warehousing is such an important function within a company, the authors chose to focus on this in their thesis. The purpose of this thesis has been to examine the significance of a Warehouse Management System (WMS) and item identification with attention to logistic efficiency.

The aim of this thesis is to investigate what information needs arise from the interest in music, which sources are preferred, how this information is sought and what part does the public library play in providing music materials. Brenda Dervin`s Sense-Making theory is what serves as a theoretic framework for this study. A qualitative approach was undertaken in the investigation and nine interviews were conducted with people interested in music. Findings indicate that different ways of acquiring information are used depending on the situation in which the information is needed and also what kinds of music people prefer. The main findings of this study suggest that people interested in music are keen to constantly discover new music to perform or listen to.

This thesis researches the construction of the Swedish masonry heater called r?rspis. A r?rspis has an inner smoke channel system that stores heat and it was developed in the early 19th century alongside the Swedish kakelugn (tiled stove). Unlike the tiled stove, the R?rspis was commonly found in simpler environments and is part of the cultural her itage of the rural population.
