Modellbaserad systemutveckling i komplexa verksamheter. En fallstudie av Coremetoden

In system development it is today increasingly common to use a model-based system development method. These methods that are suited for Agile work with simple and quick updates and implementations of new applications in systems conform to the requirements that are becoming more important today, namely more flexible and less expensive system that still maintain high quality and safety.A company that has been working with this type of system development method for a long time is Genicore AB, which also has developed their own tools and model language in order to better model the information management systems in complex and abstract operations. Genicore AB is trying to spread their method other developers and have therefore taken the initiative to start this study. The method is evaluated and tested by two students with relatively little experience in model-based systems engineering in order to gain a new perspective on how the method functions. The method has been applied to an educational activity in order to test it in a new domain, and this led us to our research question;?What criteria are of particular relevance in the implementation of a MBSD method on on complex businesses??Through literature reviews and interviews, we formed an idea of how model-based system development works from a theoretical perspective, and then continued to the case study conducted on the educational activities at the faculty of IT at University of Gothenburg.

Ett företags internationaliseringsprocess : - i ett land kulturellt skilt från dess hemmamarknad

AbstractPurpose:The purpose of the study is to describe the internationalization process of one firm when in a country culturally diverse from the firm?s original market.Methodology/approach:The study is a single case study which examines one firm?s internationalization process when entering the Chinese market. The approach has been an empiric interaction between empirical and theoretical data.Findings:The theory of the Uppsala model was applied to the case-company to test the model?s completeness. The authors found weaknesses and added three more aspects to the model.

Livskvalitet hos personer med cancersjukdom inom palliativ vård

AbstractBackground: Cancer is a leading cause of death worldwide and accounted for 7.6 million deaths, about 13% of all deaths, in 2008. Several factors can affect patients' quality of life such as physical and psychological symptoms, relationship to people around and the environment. In palliative care professionals need to have good knowledge in order to improve patient quality of life and to give them as good a life as possible in the final stages of life.Aim: The purpose of this overview study is to describe the experiences of quality of life in patients with incurable cancer.Method: We conducted an overview study that was based on ten scientific articles. All articles are qualitative studies, from the year 1995 - 2011, and are from Sweden, Finland, UK, Canada and the USA. Qualitative analysis was used to group the various themes and subthemes for overview study purpose.

The aim of this Master?s thesis is to examine how a person?s library use and reading can change with time. It also examines how different factors in a person?s context or in the life situation can affect these activities. The analysis is based upon qualitative interviews with three persons, two women and one man between 67 and 69 years of age.

Livscykelanalys av sex olika fiskodlingssystem : Fiskens miljöpåverkan för konsumtion i Stockholm

This thesis evaluates the environmental performance of six different fish farming systems. The thesis is part of the network group ?Hållbar fiskförsörjning I Stockholms län? (HFFS) which tries to increase the domestic and regional production of fish in Stockholm and move to a more sustainable supply in the Stockholm county. Two of the chosen systems; pangasius from Vietnam and salmon from Norway are delivering a substantial part of the fish consumed in Stockholm today, although they are very different when it comes to system characteristics. One system, arctic char with conventional feed, is produced in a fairly small scale in the north of Sweden, while the three remaining systems are viewed upon as possible options to supply Stockholm with fish in the future.

Gestaltningsförslag till ny förskola på Zakrisdal

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

Viktiga faktorer för utländska direktinvesteringar i Sub-Sahara : en tvärsnittanalys

FDI har sedan början på 80-talet växt sig allt större och blivit en av de viktigaste tillgångarna till finansiellt och fysiskt kapital i världen. FDI har enligt många studier en viktig funktion för ett lands ekonomiska utveckling, detta gäller främst för outvecklade länder men också utvecklade länder. Studiens mål var att hitta viktiga faktorer som påverkade FDI inflöde till Sub-Sahara regionen. Den empiriska analysen gjordes med hjälp av en OLS regressionsmodell och hade 42 observationer sammanlagt. Huvudvariabeln var FDI/BNP.

Klimatsimulering av ett kontorsrum : Hur de termiska stigkrafterna påverkar ventilationseffektiviteten

AbstractIn urban societies people spend more and more time indoors, which put great demands on the indoor environment. If the ventilation is to manage the removal of unwanted substances in the indoor air, a good mixing of the air is required. The question arises that, whether the buoyancy forces will counteract a good mixing of the indoor air or not?This report aims to clear up the difficulties whether you need to consider the buoyancy forces or not, when adjusting a ventilation unit. For studying the indoor mixing of the air a two dimensional model is constructed in COMSOL Multiphysics.

Att må bra i vardagen: en kvalitativ studie av upplevelser hos kvinnor med osteoporos

Every second woman in Sweden suffers in their lifetime of fracture that is related to osteoporosis. Osteoporosis and fractures affect the person´s everyday life. The aim of the study was to describe experiences of feeling well among women with osteoporosis. Six women were interviewed with semi- structured interviews. The interviews were transcribed and the text was analyzed with thematic content analysis.

Kan friluftsliv i tidig ålder leda till ett bibehållet intresse som vuxen? : en studie av tidigare elever vid en I Ur och Skur förskola på Lidingö

AimThe aim with the work is to investigate if outdoor life at an early age will contribute to a maintained interest as a grown-up, and what other reasons play a part in maintained/lost interest. Questions:? Are the people active within outdoor life/physical activity today?? How much time do the people devote to outdoor life/physical activity?? What factors during the growth, from preschool to grown-up, contribute to a maintained or lost interest in outdoor life?MethodSince we wanted to bring forth all eventual factors that may have effected the people in their physical activity today we chose to do a qualitative study using deep interviews. The investigated group consists of six former students, four girls and two boys, from the I Ur och Skur preschool Mulleborg. Today the respondents are between 20 and 24 years old.ResultsThe investigation shows that all respondents are active with some kind of outdoor life or physical activity today, but there is a difference in how much.

Modell och analysverktyg för beräkningav frekvensförlopp

The power system modelled in this thesis work has been developed for simulationwhen e.g. the production in some part of the power system is changed. The powersystem has been modelled according to the swing mass of the system, the frequencydependency of the load and the turbine governor. The model determines the systemfrequency, the period of regulation and the power exchange between the differentsubsystems in the Nordic synchronized system.In this model the system frequency is assumed to be the same in all different parts ofthe power system and the voltage conditions in the power system are neglected. Forthat reason power swings does not occur between different subsystems in the powersystem, which usually occur as a result of the swinging connection between thetransmissions line.

Kunskap ur elevernas vardag : En studie om livkunskap påverkan på elevernas förmåga att reflektera och hantera konflikter

The schools have problems with conflicts and mobbing. One way to deal with this is to focus on the importance of life skills ?SET- Social emotional training?. SET is a program that encourages student?s self-awareness, that is, the understanding students have about themselves and how he or she can relate to it and to others.

Värdering av tillgångar : En branschpraxis för klädbranschen och byggbranschen

The valuation of an asset is one of the most important thing with accounting, though one of the most difficult thing as well. However, in deciding useful service life for an intangible asset and property, plant and equipment, there are quite a margin for the companies, which creates a difference between companies and industries. When computing the value of the inventories there are a few possibilities available for the companies, which also can generate differencesbetween companies and industries. Although these differences can occur, there might be some similarities in the companies? estimates.

Informationssökning under graviditet: en kvalitativ studie om gravida kvinnors informationssökning via sociala kontakter

The aim of this thesis is to gain a deeper understanding of howsocial contacts can serve as information sources for pregnantwomen. Furthermore, we wanted to examine how women?scontext influences their information seeking and the barriers thatcan occur during information seeking. The theoretical frameworkis founded on Tom Wilson's model of information needs as contextdependent, and Pamela J. McKenzie's model of informationpractices in accounts of everyday-life information seeking.

Jämförelse mellan subjektiv och objektiv bedömning av hälta hos häst på böjt spår.

The female dog has a unique reproductive endocrinology, with high levels of progesterone throughout the 70-day long luteal phase. In this project, markers of glucose metabolism were studied and compared from the aspects of breed group and time in oestral cycle. The parameters studied were: glucose, insulin, progesterone, fructosamine and the newly introduced analysis of HbA1c. Hba1c was also further evaluated and discussed as a diagnostic tool in canine medicine.No differences in terms of glucose markers were found between a group of purebreed dogs of various breeds compared to a group of dogs with high risk of dioestrus diabetes, namely the Norwegian and Swedish elkhounds.No differences were found between the two sample occasions, anoestrus and dioestrus, concluding that there is no need for relating test results to the time of the oestrous cycle in middle-aged intact female dogs.There were statistically significant higher values of all glucose markers in diabetic dogs than in non-diabetic dogs. When it came to HbA1c, however, there was a larger overlap between the two groups, compared to fructosamine.
