This study is based on a statistical analysis of fundamental key ratios on the Stockholm Stock Exchange during the period 2004-2012. In total 35 financial ratios of 90 companies were tested, ultimately five ratios remained within the 5% significance level. These ratios were ROA, P/B, Total Yield, EV/EBIT and Operating Margin. A custom made investment model was created based on the purpose to achieve a risk-adjusted excess return. The results in general did not show any significant difference in return between the model's portfolio and index.

This master thesis project at KTH is performed in the Mechanical and Aerospace Engineeringdepartment at University of Florida (UF). The thesis is a small part of a gas turbine researchproject where a vapour absorption refrigeration system (VARS) and a high pressure regenerativeturbine engine (HPRTE) are integrated together. The main objective is to build a computermodel of the VARS. The computer model is supposed to be used to analyse the off-designperformance of the VARS and should also be easy to integrate as a subroutine in a more complexsystem model. To model the VARS some knowledge of the absorbent/refrigerant mixture had tobe well known, in this case a mixture of ammonia and water.

This thesis is about university spin-offs and the competition in high technology industries. In the light of efforts to increase the competitiveness of the European Union, an effective transfer of cutting edge technology from universities to the industry plays an important role. University spin-offs, start-ups founded to exploit academic inventions, are likely to face considerable market entry barriers. This is among other reasons due to high capital requirements for further technology development and lack of complementary resources. With a combination of relevant literature and empirical investigation, commercialisation of technologies within spin-offs is investigated and analysed.

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

This study was carried out in Ronneby municipality during May 2006. I chose to compare three senior schools with regards to the implementation of objective orientated directives based on the teachers understanding of the task, motivation, resources allocated and their significance for the disparity between boys? and girls? grades.I carried out nine in-depth interviews: three at each senior school. From the interviews it emerged that teachers perceive objectives differently from parents and students. Teachers claim that they understand the directives but say that they lack the resources.

The forecast ability of four well-known exchange rate models for theSwedish krona is tested in this thesis. The models that are tested arethe purchase power parity, the real interest differential model, thesticky-price model and a productivity model. In addition to thebenchmark, the random walk, they are also compared to each other.They are all tested on three different horizons one quarter, two quartersand four quarters. The mean squared forecast error criteria and thedirection of change criteria are used for evaluation of the forecastability. Only in a couple of cases are the forecast ability of thetheoretical based models significant better than the random walk..

Abstract The purpose of writing this thesis was to improve methods during requirements engineering phase. Usercentred system engineering has some problem areas, which are examined and verified to create a new guideline for developers. This guideline tends to make requirements engineering more effective and help developers create more concrete requirements. It is not uncommon that system development projects ends up with unsatisfied users or delay in deliveries. The reasons are different kinds of communication problems between users and developers during verification of requirements.

Information and communication technology (ICT) is an important part of society. Learning occurs in all contexts and many students already use various digital media in their leisure time. This article, based on a case study in a One-to-One school. It describes how teachers perceive that their teaching is influenced when their pupils get a laptop. The purpose of this study is to investigate how the focus on one-to-one influence teachers' work in the classroom.

The purpose of this study was to evaluate Komm-A, a model for usingcommunication books in clinical practice for people with aphasia. The studyconsisted of two group studies and one case study. One of the group studies had apretest-posttest design and consisted of nine couples; a person with aphasia andhis/her communication partner. The material used was Quality of communicationlife scale (QCL), Communicative effectiveness index (CETI), Goal attainmentscaling (GAS), and a questionnaire to the communication partner. The other groupstudy consisted of seven speech-language pathologists who worked with thecouples according to the Komm-A model.

Three years after the Bosman case, it was decided that a socio-cultural approach on sports be introduced in Europe. EU presented a formulation for the same purpose ? The European Model of Sport. The purpose of this formula was to maintain the socio-culture and traditional ap¬proach to all kinds of amateur and professional sports in Europe. If we were to com¬pare this model with the American model of sport, it shows many different ways of thinking in terms of organised sport.

The purpose of this thesis is to investigate if there exists a superiority between developed and developing countries, which then in turn effects the negative consequences, for the local inhabitants of Thailand, that follow from mass tourism.To be able to answer the questions that we have selected for this thesis, we chose to perform open interviews with six respondents which were all involved in the tourism industry in Thailand. Four of the interviews were carried out on location in Thailand. In order to deepen our understanding of the selected questions even further literary studies have been made as well. The theories we have chosen concern the topics of imperialism and figurations.Our empirical material gave significant results. It showed that there is indeed an imbalance of power between the western world and Thailand.

The purpose with the paper is to theoretically investigate how sensory experience and positive affect in contact with outdoor environment can promote health by 1) develop a model of the sensory and emotional processes based on multiple code theory (Bucci, 1997) and 2) examine if this model can increase understanding of the processes that takes place in outdoor recreation, the way this is described in environmental psychology research and theory. The paper starts by introducing research and perspectives concerning outdoor recreation. Different theories of nature?s health promoting effects are described. These include the restoration theories of Roger Ulrich and Steven and Rachel Kaplan, theories more concerned with outdoor activities and a theory combining these two perspectives called instorative theory. After this sensory and emotional information processing is examined through the works of Wilma Bucci and Jean Ayres. Antionio Damasio?s theories of emotion and Daniel Stern?s concept of vitalityaffects are than introduced to extend this reasoning.
