Integration av simuleringsmodeller för bränslesystemet i JAS 39 Gripen
In this final thesis two simulation models have been integrated. The simulation models are models of JAS 39 Gripen?s fuel system, software and hardware. The time consuming and costly work to develop software has made the department of fuel system to build two models in Xmath/Systembuild. The software model also simplifies the comprehension of how the software in the control computer of the fuel system works.
Bottensubstratets inverkan på föryngring av Flodpärlmussla
The freshwater pearl mussel (Margaritifera margaritifera) is threatened throughout its range. There has been a substantial decline of the species and one major reason is habitat degradation. We investigated how the substrate composition of the bottom floor affects the regeneration of the mussel by analyzing data from the Västerbotten County Board?s inventory of the freshwater pearl mussel. The results implied that fine material such as fine sediment and sand might be detrimental to regeneration whereas gravel and boulders and in particular stone seem to be beneficial.

Vilken framtid för den europeiska unionen? Om den europeiska integrationsprocessen. Ett europeiskt styre av folket, genom folket och för folket
Bakgrund och problem: Dagens företag verkar i en osäker och dynamisk miljö där marknaden ställer allt högre krav på snabba förändringar och anpassningar till kundernas behov. För att möta denna dynamiska omgivning har en rad nya produktionsfilosofier introducerats. En av dessa som fått stor uppmärksamhet och vars användning ökat är lean.Under senare år har det kommit att riktas stark kritik mot tillämpningen av traditionell ekonomistyrning och att denna kan vara skadlig vid tillämpningen vid lean. Andra forskare tar det steget längre och ställer sig frågan om det finns någon plats för ekonomistyrningen vid operationella koncept.Som ett svar på ovanstående kritik introducerades lean accounting, ett ämne som fortfarande är hårt debatterat inom managementlitteraturen. Andra forskare skiljer här på lean accounting och lean control, där lean control fokuserar på output, behavioral samt social control.
Balanserade styrkort i statliga organisationer - Om, hur och betydelse?
AbstractBachelor thesis G3 in Business Administration, Linnaeus University School of Businessand Economics, Financial Control, 2FE90E, Spring Semester 2010Authors: Kennerth Eriksson and Leo H KochAdvisor: Lars-Göran AidemarkTitle: Balanced Scorecard in governmental organizations ? About, how and its meaning.Background: The Balanced Scorecard is a Control System that includes both financial andnon-financial measures which intend to link the short-term business management with the long term vision and strategy. Businesses in the public sectors are different fromthe private sector on several levels and they often seek to reach multiple targets.Therefore, their choice of Control System becomes interesting. According to the SwedishNational Financial Management Authority (Ekonomistyrningsverket) among others, thereis no clear knowledge of how widespread the Balanced Scorecard is in governmentalorganizations. The lack of that knowledge is one of the questions at issue with this thesis.Is it only a few organizations that are using the Balanced Scorecard or parts of the model?Another question at issue is about how the Balanced Scorecard is used in the point ofcontrolling in the organizations we chose to investigate further.Purpose: The purpose of this thesis is partly to investigate the existence and use of theBalanced Scorecard in governmental organizations and partly to describe the design ofthe Balanced Scorecard in the studied organizations and explain why they have chosen towork with the Balanced Scorecard and what impact it has on them.Demarcation: The first part of this study has been demarked to only look at the existenceof the Balanced Scorecard in governmental organizations.
Mätning av partikelmassa i avgaser från en dieselmotor
This master thesis was a continuation of a previous study in the diesel exhaust characterization, which is part of the academical work embedded in the EMIR-1 project. The main objective of this thesis work was to finish the installation and make the proper modifications of the particulate mass measuring system located in one of the engine test cells at KTH, in order to be able to measure the mass of the particles from the exhaust of diesel engines.This experiment requires a diluted flow sample from the exhaust that should be sent to the device that makes possible the measurement of particle mass, called TEOM. In the first stage of this project, the objective was to study and make the proper modifications in the existing KTH diluter because there were several problems to obtain a constant dilution ratio from it during tests.This modifications were made and it resulted in a great improvement in the maximum inlet and outlet flow that this diluter can handle. Therefore another modification is proposed for controlling the inlet exhaust flow so it will be possible to regulate the dilution ratio and make it constant along a wide range of engine loads and speeds.The second and most important stage was to make particulate mass measurements possible by analyzing the frequency signal from the TEOM device. The idea was to obtain the frequency of oscillation from the tapered element in the TEOM, and therefore with the proper correlations, be able to predict the particulate mass concentration in the exhaust flow from the engine.An electrical problem in the TEOM circuit was detected and corrected, so the signal that carries the frequency from the TEOM can be analyzed properly.
IT-stöd för riskhantering : En studie av risk och kvalitetsarbete vid ZERT AB
This paper presents a project and literature overview about how risk management and quality sometimes goes hand in hand and sometimes in two different directions. Meaning that the risk management can affect product or process quality differently depending on what risks an organisation chooses to control.The purpose with this paper is to get a deeper understanding about how risk and quality works together with IT-support and therefore we have been actively participating in a project with a risk management company called Zert. A literature study and a qualitative interview study have also been undertaken to see what the customers and the other researchers have written, to be able to make proper conclusions on the subject.To easily work together and get the information that was needed, four methods where used. Besides the qualitative interview and literature study the think-out-loud, card sorting and a variation on the extreme programming method where used to help visualize and improve communication both with Zert, the costumers and among ourselves.Zert is a risk management company that helps other organisations to control their different types of risks that they might be taking, by offering a system where the risk management process is held and providing consulting services by helping within the processes. Both Zert and their customers see the communication, knowledge and teamwork as something important as well as the quality within the work, processes and the end result.
Ledarskapstilar i klassrummet : Utifrån lärarperspektiv
The purpose of this study was to see how teachers experience their own leadership style and how they did to get their leadership to work in the classroom. The purpose was also to understand the teachers? actions, what they think is best for the students? development and how they describe the leadership in the classroom. I interviewed six female teachers and they all have had many experiences since this is their profession. My research was based on Stensmo (2000).
Användande av avskjutningsstatistik i förvaltning : påverkar tidigare jakt CPUE?
In fisheries, there is a long tradition to use catch data when evaluating changes in the stock and effects from harvesting. It is a common practice to use Catch Per Unit Effort (CPUE) as an index of population size, and several studies have investigated the properties of CPUE in relation to population abundance, spatial distribution and efficiency of gear. In research, catch rate on trap-transects is used as an index of abundance for wildlife species but CPUE is rarely applied as a tool in harvest management.In 1993, more than 60 000 km2 of the state managed mountain range in Sweden was opened to the public for small game hunting, under the responsibility of the county administrative boards in Jämtland, Västerbotten and Norrbotten. The total area is now divided into 332 hunting units (median=73 km2) and an internet based system is used to administer licences and reporting bag statistic. Each hunter has to register the results within two weeks after the hunt.

Katterna på Kattstallet i Åkeshov : vilka katter är det som insjuknar?
The aim of this study was to see if there is any group of cats that are at greater risk to get sick and/or be euthanized during their stay at a cat shelter with no-kill policy. The study was conducted at Åkeshov cat rescue center in Sweden and cats that entered the center between the 1th of June 2010 and the 31th of December 2011 was used in the study. This study focused on factors regarding gender, origin, level of socialization, incubation period and the proportion of euthanized cats. In this study, the kind of illness weren?t taken into account.
This study showed that the gender of the cat didn´t affect the risk for illness.
Utredning av frekvensregleringens påverkan på mekanisk utrustning i en kaplanturbin
As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which ensures that the grid frequency is stable and close to 50 Hz.However, setting the turbine into frequency controlled operation may cause stress and wear of the components in the mechanical control system. Frequency controlling implies large and frequent servo forces and longer travelling distance of the sliding bearings in the Kaplan turbine.Based on one selected Kaplan turbine, Selsfors G1, measurements and MATLAB calculations have been performed in order to determine forces and movements of the linkage system. With these forces and movements as input, stresses and fatigue have been determined as well as sliding distances, bearing pressures and wear of bearings during a typical lifetime of 40 years.The results indicate that no severe wear exists on the bearings during 40 years of service.
Oxytocin-Ett risktagande eller en tillförlitlig behandling vid långdraget förlossningsförlopp hos förstföderskor
Background: Breastfeeding frequency decrease in Sweden and infants born preterm is a particularly vulnerable group to not be breastfed according to current recommendations. Mothers of preterm infants have an extra need of support from the health care system. Mothers' self-efficacy in breastfeeding affects the outcome of breastfeeding. Health professionals' attitudes to breastfeeding have an impact on the breast feeding support they provide to the mothers.Aim: To investigate whether an intervention could strengthen self-efficacy in breastfeeding among mothers of premature babies. A further aim was to investigate whether the intervention influenced health professionals' attitudes to breastfeeding.Method/Design: An experimental study with quantitative approach in the form of questionnaire survey was conducted.
Biological control of Fusarium wilt on tomatoes : use of Bacillus subtilis and interactions with the earthworm Pontoscolex corethrurus in a Kenyan highland soil
It is important to investigate the potential of biological control measures in agricul-ture, especially where economic issues restrict the use of expensive inputs or when there are environmental concerns about toxicity of agrochemicals. The bacterium Bacillus subtilis has proved promising as a biocontrol agent (BCA) in suppressing various plant diseases and it has also been shown to promote plant growth in certain cases. During this study, the effect of B. subtilis on Fusarium wilt (caused by the fungus Fusarium oxysporum) on tomatoes, as well as its effect on the earthworm species Pontoscolex corethrurus was investigated. Furthermore, the combined ef-fect of the BCA with P.
