In this study a multiple linear regression was carried out in the interest of analysing a number of variables effect on the final prices of apartments in Stockholm?s inner districts. The result may be employed to predict and observe percentage changes on the final price of apartments in Stockholm in the future. Five models were constructed after which they were analysed and compared. The construction of these models were supported by data from the real estate agency Erik Olsson.

Introduction: Analysts worldwide valuates stocks and companies by using different valuation models. The models are used to calculate how much public company?s stocks are worth and to identify whether stocks are over- or undervalued.  Objective: The objective of this essay is to study which valuation models are mainly used by financial analysts in Swedish banks. The purpose is also to study how reliable these models are considered. Method: The empirical study is based on a qualitative approach through interviews with financial analysts. The study includes both primary data (interviews) and secondary data (literature, websites and scientific articles)Theory: The theory chapter includes methods of analysis (fundamental and technical analysis), Valuation models, components of valuation and an example of a valuation with the Discounted cash flow model. Empirical study: The study includes a qualitative research that consists of interviews with financial analysts.

The problems with train-induced vibrations are increasing with heavier and faster trains. Therefore the work with propagating vibrations is of outmost importance, and that is what this thesis relates to.To get a sensible idea of the propagation, calculation models are often used. Propagation calculation models takes into account factors such as distance to the railway, the ground material and the velocity and weight of the train. This work is mainly about finding suitable existing models and, if necessary, adjust them to be more useful with modern trains and railways.The report contains the work of adjusting one such model and does, despite the fully functional adjusted model, describe how much more there can be done within this topic. Finally, a few tips about specific areas that preferably should be studied to get even further knowledge about the troublesome problems from railways..

The aim and purpose of the following study is twofold. The first part aims at clarifying different models of migration policy available within research of political science. The second part of the study applies the identified models onto an analysis of the official report ?Integrationens svarta bok? and the suggestions the reports presents. The findings of the study are multiple.

Wind is used as an energy source all over the world. To be able to use this effectively, there is a need for as good forecasts and forecast models as possible. One of these models is Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS®) that is used to calculate short time forecasts. This model is used here to calculate wind speeds at two different areas in Västra Götaland, Bengtsfors and Vänersborg. There are also wind measurements with SODAR stations for these areas.

Today, activities funded with public funds needs to present relevant and reliable information which shows the results obtained. Requirements increase in welfare activities to be run based on scientific, empirical knowledge. This applies particularly to social work. The social work is, however, poorly researched in areas such as knowledge of interventions in the content, context and effects. One way to evidence-base social work can be to conduct regular and qualified assessments.

This paper describes a study examining four different GARCH models AR(1)-GARCH(1,1), AR(1)-EGARCH(1,1), AR(1)-APGARCH(1,1) and AR(1)-GJR-GARCH(1,1), and their ability to predict future volatility and thereby providing more reliable estimates for Value-at-Risk. The study is based on daily observations for the return of the OMX Stockholm 30 Index, during the time period 31st December 1996 to 29th December 2006. The coefficients for these GARCH models have been estimated using a five-year rolling estimation window, with one-year lags, for five different in-sample-periods. These five in-sample-periods, and the coefficients given by them, have been used to generate five out-of-sample predictions for the volatility in each year. Using these volatility predictions, the daily Value-at-Risk has been calculated for confidence intervals of 90 percent, 95 percent, and 99 percent, respectively, during the time period between 1st January 2001 and 29th December 2006.

This thesis studies the way valuation of investment properties is conducted in accordance with IAS 40 and how reliable these valuations are. This has been conducted by studying ten Swedish real estate companies listed on the NASDAQ OMX, during the period 2005-2008. The study shows that all companies use valuation models to determine the fair value of investment properties. Two different types of models have been identified. Companies that use the cash flow model show inconsistencies in time horizon, and how they determine the horizon value.

This thesis has been a part of Forsmarks Kraftgrupp AB's evaluation of a turbulencemodel used in simulation of turbulent flow called PRNS (Partially Resolved NumericalSimulation). This model has promising properties and may be of use in savingcomputational resources. The purpose of this thesis was to analyze this model andcompare it with industrially applied models such as k-omega SST and LES (Large EddySimulations).PRNS works as a hybrid of the k-omega SST and DNS (Direct Numerical Simulation)where a constant, RCP (Resolution Control Parameter) with a value between 0 and 1are selected. This constant is then used in the calculations and determines thebehavior of the simulation. When RCP is set to zero the equation are the same as fora DNS simulation and when RCP is set to one the equations for k-omega SST issolved.

This study attempts to explore how schools? handles and prevents cyber-bullying among pupils. The purpose in this study was to investigate how the school staffs work in secondary schools with grades sixth to ninth. How do the schools discover, prevent and stop cyber-bullying? Do the schools? have any experiences of cyber-bullying? How do the schools work with anti-bullying concepts ? have the new phenomenon cyber-bullying affected and changed the schools´ anti-bullying work in connection with the guidelines and in relation to the "new technology"? This study attempts to examine how this is handled within several secondary schools with three different municipalities.

Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.

In this paper I have sought a suitable level of abstraction in my models describing the landscape; the models are made to be viewed from eyelevel. Because of the spectator being ?in the model? the objects included need a certain degree of realism. I have sought what is needed in the model to be able to comprehend that the model is showing a landscape. Some details might be unnecessary.

This two year masters thesis is written in the scientific field of library- and information science. The purpose of the study is to investigate the collaboration between teachers and librarians in different types of school library organisations. Two school libraries with only the school as a target group, two integrated public- and school libraries, one school library division and one public library that provides the school with school library services has been studied. The study takes place in Uppland.The theoretical framework used is based on Montiel-Overall and her four models of collaboration: coordina-tion, cooperation, integrated instruction and integrated curriculum. The first research question focuses on the col-laboration between teachers and librarians based on each of the TLC-models.

This is an explorative study about subject indexing of a special collection of books, administered by the John Andrén Foundation at the library of Ystad. The study summarises a number of theoretical perspectives as well as some practical instructions on how to carry out the task. Theories have been placed into five different groups according to their various approaches to subject indexing. These have been analysed in regard to their usefulness to the Andrén collection. The authors have tested and evaluated six practical models on a selection of books from the Andrén collection.

The role distribution between designers and product coordinators and the system support between these roles are adapted according to the method of working that product models primarily are created for production and after sales market. At the same time models are also created to support a cross-functional way of working. This means that product structures exists on paper and as CAD-models before they are created in Scanias PDM-system environment which leads to unnecessary work and to information not being shared as early as it should be possible.A theoretical study has been performed with the purpose of understanding the problems and to create a foundation for improvement suggestions. Representatives from both roles have been interviewed together with other individuals with insight in the collaboration. A minor study concerning the roles of interests? collaboration at Volvo CC was also performed to be able to relate the study to another company.
