The purpose of this thesis work was to develop an automatic fault detection system for surveillance of bearing temperature in hydropower turbines. The parameters used except the bearing temperature were cooling water temperature and cooling water flow. A simple static model based on data sampled every minute was developed to estimate the bearing temperature. Then a detector for detection of change in bearing temperature based on the CUSUM-algorithm was designed. Since the amount of data was very small the developed model was too uncertain to be used in a working system.The designed fault detection system showed to work well for the available data.

Volvo Construction Equipment i Braås är världsledande inom tillverkning av ramstyrda dumprar. I Braås utförs därför en mängd olika testfall där man kartlägger utfallen genom insamling av data från CAN-bussar i dumpern. Om ett test går fel beskrivs det i en felrapport med tillhörande beskrivning av händelseförloppet. Idag finns det inget enhetligt sätt att visa händelse ihop med position.För att analysera insamlad data används idag CANalyzer. Fördelen är att det går att visa insamlad data på ett strukturerat grafiskt sätt.

This master thesis was made to validate hydropower models of a turbine governor,Kaplan turbine and a Francis turbine in the power system simulator ARISTO atSvenska Kraftnät. The validation was made in three steps. The first step was to makesure the models was implement correctly in the simulator. The second was tocompare the simulation results from the Kaplan turbine model to data from a realhydropower plant. The comparison was made to see how the models could generatesimulation result that was similar to the reference power station.

Datorspelsbranschen är en relativt ung bransch, både jämfört med andra delarav mjukvaruindustrin och nöjesbranschen. En av de stora utmaningarnaspelutvecklare står inför är planeringen av den långsiktiga kompetensförsörjningen.Dock saknas sammanställda historiska data och applicerbararesursestimeringsmetoder, vilket gör detta arbete näst intill omöjligt. Det förstadelmålet med den här studien är att samla in historiska data angående strukturenoch storleken på utvecklingsteam som utvecklat AAA-spel (professionelltutvecklade spel med en hög budget) för pc-datorer. Datan samlas in frånkreditlistor hämtade via webbsidan Mobygames.com. Det andra delmålet beståri att utreda huruvida den insamlade datan kan appliceras på modeller förestimering av framtida personalbehov.

The initial provisions concerning CFC-legislation were introduced 1990 and has since been subject to several revisions and adaptations. The fundamental purpose of the CFC-legislation is to prohibit and prevent tax evasion undertaken by such companies that own other foreign companies where generated income is subject to low rates of taxation. The CFC-legislation aims to provide the Swedish government with an op-portunity to tax this income. This is important in order to prevent tax avoidance and preserve the integrity of the system of taxation within Sweden. In order for the CFC-legislation to be as effective as possible there must exist a clear way of defining which activity that is to be regulated within its scope.

Opcon Powerbox is a product developed by Opcon together with the underlying company SRM (Svenska Rotor Maskiner) where surplus heat from the industry is used through an Organic Rankine Cycle (ORC)?process to produce electricity. An ORC-process is a thermodynamic circle process in which a refrigerant is used as the working fluid. The refrigerant makes it possible for the circle process to operate at lower temperatures than the conventional Rankine process.In this master?s thesis a data analysis software for the Opcon Powerbox has been developed in which measurement data is retrieved and handled from the Opcon Powerbox.

The thesis mission is to investigate whether the swiveling laser that Vectura (former Vägverket Konsult) has in use to measure the road areas and straddle measuring can be used to detect differences in the reflective road markings function. This is to increase use of the swiveling laser and get rid of the manual measurements performed today.Currently, the measurement of road markings reflective function is performed with both mobile and handheld measuring instruments. The purpose of this thesis is to develop better methods for determination of road markings? reflective function, in order to facilitate the description and suggestions for improvements of the maintenance of road markings reflective function.The questions that the thesis has been to start with are:Can the swiveling laser detect differences in longitudinal and transverse road markings reflective function?The accuracy of measurement has been sweeping the laser over the reference instrument (LTL-2000)Is it necessary with a conversion factor for swiveling laser data against the reference instrument data?To answer the question 2 and 3, there has been a field work in Värnamo where a road stretch with longitudinal road markings and zebra crossing (transverse road markings) has been investigated with a swiveling laser and LTL-2000.The formulas and calculations contained in the thesis are drawn from scientific reports that are produced by VTI in Linköping. The same formula that was used to calculate the optical measurement data was also used for the swiveling laser data.

Thinning is one of the most important silvicultural activities in middle aged forests, partly to minimize damages and partly because it leads to earlier harvesting revenues and increases the value of the remaining trees. There are many different indices used to describe stand density and thereby the need of thinning in forests today. Studies have shown that forest variables can be estimated with high accuracy using airborne laser scanning and it is likely that the method could also be used to estimate forest density indices. In this study, the possibility of using the forest density index ?H² to determine and map priorities for thinning operations for a forest area was examined.

Previous research and patient complaints to the Swedish Patient Support Committee shows that there is a lack of substance in the patient-nurse relationship. This may suggest that it can be difficult for health care to live up to health-care law which requires it to be of good quality, based on dignity and respect and designed so that the patient is an active participant and can make their own decisions when it comes to their health care. For a better understanding of what a dignified patient-nurse relationship is, this study aims to clarify what the patient values as good patient-nurse relationship and describe how they have experienced the patient-nurse relationship during their stay at an emergency care department. The study is a descriptive cross-sectional study with a quantitative approach, where the population consisted of patients who were cared for at an emergency care department in the County of Västmanland, Sweden during 2007. The sample consisted of 93 patients which were asked to answer a questionnaire.

Metadata är en viktig del i arbetet med geografiska data. Med bra metadata kan användaren på ett enklare och effektivare sätt hitta de data som är intressant för just honom eller henne. Länsstyrelsen i Västmanland har stora mängder geografiska data och beslutsdokument som rör geografiska områden. Dessa geografiska data och dokument lagras på servrar och är tillgängliga för handläggarna (användarna). GIS-gruppen har tidigare lagrat metadata för dessa geografiska data i en databas uppbyggd i Microsoft Access men en nyutvecklad metadatabas, GisMeta, ska börja användas.

In this thesis I examine the events that followed the death of August Strindberg and resulted in his private belongings becoming an important part of Swedens cultural heritage. My purpose has been twofold: firstly, to identify which aims were sought to be achieved when dealing with Strindberg's archives and his home and to relate these to a nationalistic interpretation of history, secondly, to relate this work to the then newly introduced archival principle, the Principle of provenance. I identified three different aims: firstly the economic aim must be seen in the light of an increasingly expanding publishing market. I argue that the author gained a new and important role in the general social debate a nationalistic one, an important point with regard to my following conclusions. Secondly, the aim to store and display the material in a museum is discussed in relation to different views of cultural history and the interpretation of history.

This reports purpose is to give a general view on how to handle information collectedthrough photogrammetry and laser scanning with the help of UAS. The report ismade in collaboration with WSP Group and will briefly describe howphotogrammetry and laser scanning, also known as Lidar, works and how those areused in the construction business today. Then the focus will be on how gathered datais handled today, how outsourcing of data should be approached and if there are anyconsequences if data is handled in the wrong way. Interviews have been made with allparts in the UAS business. That includes authorities as Transporstyrelsen,Försvarsmakten.

This thesis seeks to investigate how an agreed written form requirement is met in an electronic environment. Swedish Contract law is applied since Sweden lack specific regulation for electronically closed agreements. Since contractual freedom prevails in Swedish law, it is up to the parties themselves to decide if the formal requirements to be applied.In order to assess whether the written requirement is fulfilled in the electronic environment, a purpose-oriented analysis should be made. When the purpose of why a written form requirement applies has been clarified, the analysis continues to assess whether the objective can be achieved with the modern form of communication. The method is called functional equivalence and means that when an electronic media fulfill the same functions as the paper medium so will the electronic medium as a starting point to give the same legal effect as if it were the case of a written paper document.

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..
