Three methods of sensitivity and unceartainty analysis have been applied to the operative stormwater- and recipient model StormTac. The study area is the watershed of lake Flaten in the municipality Salem. StormTac?s submodels for stormwater, pollutant transport and the recipient are cosidired. In the sensitivity assessment, the model parametres and inputs were varied one at a time by a constant percentage according to the ?one at a time? (OAAT) method and the response of the outputs were calculated.

Title: A study about the purchasing process of ITLevel: Master thesis in Information Technology and Business Administration, 15 hp, EIK024Authors: Emelie Johanson and Mikael LindströmTutor: Peter Ekman, Mälardalens HögskolaKeywords: IT-investment, purchase, decisionProblem: In the last decades the amount of IT investments increased and has become an important resource within most organizations. IT gives the ability to compete and could also be a condition for many to be able to compete. In different businesses it could vary in where they put their focus when they choose an IT investment. This thesis examines how the purchase process of IT looks. How does processes differs in a bigger company versus a smaller company? From these two perspectives this study examined these research questions: Who makes the decisions whether or not an IT solution should be purchased? What aspects decide when companies are to choose between different IT solutions? Where in the purchase process do problems usually emerge?Purpose: The purpose of this thesis is to describe and analyze the purchasing process of IT from a business perspective.

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 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.

AbstractTitle:                           What is the interaction between information providers and decision makers like? A case study on management accounting in Swedbank.Course:                              Master?s thesis in Business economics, 15 ECTS.Date:                                                        2009-06-01Authors:                            Daoud Ghorbandi and George TekmenSupervisor:                        Paula LiukkonenLanguage:                         SwedishPurpose:        The purpose of the paper is to study the relationship between information providers and decision makers regarding the quality of information for economic decision-making in companies.Method:                     The authors use the qualitative method approach. The essay's primary data consists of data collected through interviews, while the literature that the authors have made use of for the interpretation and analysis of the paper form the essay?s secondary data.Theory:                      It includes a main theory and four other theories supporting the paper. The main theory is the agent theory, while theories on information quality, the theory of outsourcing of management accounting, theories of calculation methods and regulations on management accounting is to support the analysis and conclusions made in the paper.Empirical base:          Interview Responses forming the essay?s primary data is presented in its entirety in this chapter.Conclusions:              The authors conclude that there are no major problems or obstacles in terms of internal management accounting in Swedbank, at least not in the departments such as the HR and the GF.

The accounting of today results in reports that are valued according to one kind of value.There are advocates who recommend that the accounting should be expanded by one orseveral columns, which would enable that other methods of valuation could be used. In thisessay we examine how the ?multi column reporting? can alter the outcome of a financialanalysts? valuation procedure.In this essay we used existing theories about the financial analysts? usage of information toreach the lack of information we found and which we aim to erase whit this essay. To do thiswe studied decision theories and theories regarding information processing, and by interviewswith three financial analysts. After we collected the information needed for the analyses, wethen also compared the results of the interviews with related theories.The theories about decision in this essay concern whether a decision is based on rationality,bounded rationality or irrationality.

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.

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.

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.

In agricultural educations you learn to use different economic planning tools, as basis for decision. The purpose and goal of this work has been to find out if economic planning tools are used by the farmers in Sweden. We choose to do an investigation through personal interviews, and used an inquiry to get as equivalent answers as possible from the farmers. This work contains a literature study with relevant facts about the questions that is brought up in the inquiry. This study of literature explains shortly some different calculation methods and bases for decision. It also contains useable information that is important to know before an investment. The questions that are asked to the farmers have focused on the use of calculation methods and economical planning tools.
