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..

The study aims to investigate the impact of industrialised homebuilding in the creation of the aestheticproperties of the dwelling architecture.The concepts of industrialised homebuilding and the aesthetic properties of the dwelling architecture aredefined by previously developed models. In these models, industrialised homebuilding is described byeight characteristic areas. The aesthetic properties of the dwelling architecture are described by sevenaesthetic qualities.The study was conducted as a qualitative study, and in-depth interviews were conducted. The companyJM AB is the analysed unit that the author of this report has chosen to study. JM employees and by JMhiredarchitects were interviewed.The report concludes that characteristic area planning and control of processes are considered to havepositive impact on the aesthetic qualities if the process is designed in such a way that the creations ofthese are admitted.

This thesis compares different methods for risk assessment of a creosote contaminated site in Vansbro, Dalarna. In a complementary study the importance of using representative data for calibration and validation of stationary groundwater models is discussed. The time dependency between surface water levels and groundwater levels on the site in Vansbro is evaluated by step response analysis. The results show that the groundwater levels reflect only long-term variation in the surface water levels. Hence the use of such long-term means for calibration and validation of the stationary groundwater models is the only theoretically defendable alternative.As a first step in the comparison of risk assessment methods the degree of contamination is evaluated on the basis of generic guideline values for contaminated soils, developed by the Swedish Environmental Protection Agency.

This study is about to see whether the two models representing the strategies of lean production is to use and apply in different companies. The models are structured in two different ways in which one of them is checking the softer elements of lean production in the form of leadership and strategies. This model is called Lesat and is based on interviewquestions. The second model, called "learning to see" is about identifying flows. This, together shall then give an idea of how mature companies are when it comes to a whole in the concept of lean production, and susceptibility to use these models to their respective companies. The study is conducted in two companies, SKF couplings systems and AQ parkoprint.

Value-at-Risk (VaR) is among financial institutions a commonly used tool for measuring market risk. Several methods to calculate VaR exists and different implementations often results in different VaR forecasts. An interesting implementation is historical simulation, and the purpose of this thesis is to examine whether historical simulation with dynamic volatility updating is useful as a model to calculate VaR and how this differs in regard to type of asset or instrument. To carry out the investigation six different models are implemented, which then are tested for statistical accuracy through Christoffersens test. We find that incorporation of volatility updating into the historical simulation method in many cases improves the model.

The purpose of this work is to develop and test a design process where quick decisions and model building has a prominent role. The goal is to develop a number of products and build prototypes to be shown during the Carl Malmsten Furniture Studies spring exhibition 2012. I?m also writing a report describing my work.To reach my goal I have each day during the first phase conducted a short research and found a concept based on that days name day. Then I have continued in the workshop and worked with three-dimensional models.

The potential of information technology as a means to invigorate democratic practise is constantly under discussion. Regardless of the differing opinions as to the most suitable way to utilise IT, there are certain democratic core values that have to be considered. One of these is freedom of information, defined by us as the right of every citizen to seek, obtain and express information. The aim of this study is to explore whether the use of IT as a means to enhance democracy can strengthen the citizens right to freedom of information. As an instrument for analysis we use an article by Jan van Dijk, professor of communication science.

The purpose of this study is to examine the view of Swedish language teachers on the role of fiction and of school libraries within the compulsory school?s teaching of Swedish of form 6-9. The questions to be answered are:? What part do Swedish language teachers (hereafter called teachers) think fiction is playing regarding the pupils inclination to read and reading promotion?? What is the attitude of teachers regarding the function of fiction in the Swedish subject?? What do teachers consider being the role of the school library in education, and can this be related to the local school library resources?To answer the questions a questionnaire was sent out to thirty-five teachers. Four qualitative interviews were also carried out among the fourteen teachers that answered the questionnaire.

By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.

The purpose of this bachelor-thesis is to investigate the possible effects of lease accounting on the estimation of bankruptcy. This is done by estimating the risk via prediction models based on accounting ratios for a sample of 43 listed firms in Sweden. Estimation is conducted twice for each firm, once base on unadjusted data as it is presented in the annual report of 2012, and one with data adjusted for operational leases (that is data is treated as if all leases present were to have been reported as financial leases). In the next step it is tested weather the predictive ability of the models is affected by this adjustment or not. For this purpose translation of bankruptcy risk into synthetic credit ratings via interest coverage ratios is done.

Do ceramics have to be static? This was the question that spurred me into this work, and what kept me working on to achieve the possibility of motion in my ceramic objects. By combining the knowledge gained through my former education as an avionics technician with my interest in the ancient ceramic craft, I strive to create kinetic ceramic handicraft suitable for interaction with an audience.By a series of different phases I slowly go from understanding what kind of motion I want my objects to have, to actually realizing this motion in three-dimensional objects. Through the use of simple models made from corrugated fiberboard followed by more advanced plaster models, combined with different complementary materials such as bicycle inner-tubing and recycled aluminium cans among many others, I, through a vast series of testing, slowly build up a knowledge base later applied to the ceramic objects.The result is for me a success; I have found a way for me to combine ceramics with mechanics. Through this I have created kinetic ceramic handicraft intended for interaction with an audience..

The purpose of this study is to give a description of how six pedagogues in the third and fourth grade teaches mathematics and which working methods they use. When using the term working methods it is implied that it can for example be outdoors pedagogic, laboratory material, problem solutions et cetera. This material can both be an everyday material or a pedagogical material. The research was carried through by interviews and observations. Six pedagogues were interviewed in two different districts.

Purpose: The purpose is to research different co-operations between venue owners and WISPs, when WLAN is deployed in a public space. The aim is to establish viable business models for the interaction between the two vital actors in the public WLAN industry. In this work, the advantages and disadvantages of revenue and cost sharing will be defined, along with technical and commercial issues that need to be resolved. Methodology: A number of case studies of the current situation have been conducted in the most attractive venues for WLAN, airports. As the public WLAN market had most widespread adoption and is most mature in the USA, case airports were chosen both there and in Scandinavia.

The purpose of this Bachelor thesis in Economics at Lund University is to try to establish the correlation between the value change of retail real estate buildings in Sweden and macro economic variables. The principal method is the multiple regression model and it is used to estimate the basic model. The basic model is enhanced by estimating some 30 models and the result is two good models. The difference between the basic model and the two better models are small but important. In the lagged basic model, the same variables are used as in the basic model but with different time lags.

This report is part of a Bachelor?s degree corresponding to 15 creditsat the Royal Institute of Technology, Stockholm. The work hasbeen carried out by Max Wikander, author of the report, supervisedby Lanie Gutierrez-Farewik and Erik Dijkstra.Gait analysis includes measurement, characterization and assessmentof human movement and is used to assess kinematic or otherabnormalities during gait. Center of rotation and the axis of rotationof a joint are fundamental parameters in motion analysis. However,the ability to create individualized analysis is limited by the lack ofaccuracy when these parameters are calculated.
