    "Så", ska det taggas som adverb?: En granskning av hur annoteringsverktyget Swegram ordklasstaggar elevtexter i svenska och svenska som andraspråk2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den här uppsatsen undersöker hur väl annoteringsverktyget Swegram utför analysdelen ordklassbestämning, så kallad ordklasstaggning, av elevtexter i svenska och svenska som andraspråk. Syftet är att undersöka tillförlitligheten i verktyget och om avvikelser i ordklasstaggningen finns från manualen till SUC (Ejerhed et al 1992) samt från traditionell grammatisk ordklassanalys enligt SAOL vill jag undersöka i hur stor omfattning det sker och i vilka ordklasser det är mest frekvent. Studien ämnar ge svar på om vissa ordklasser är mer problematiska att ordklasstagga än andra, om vissa ord har egenskaper som ger upphov till feltaggning och om det är skillnad på verktygets förmåga att känna igen och ange ordklasser i texter skrivna av elever med svenska som andraspråk i jämförelse med texter skrivna av elever med svenska som modersmål. Materialet består av tio elevtexter i ämnet svenska som andraspråk och 10 texter i ämnet svenska för årskurs 9. För att få fram statistik på avvikelser i ordklasstaggningen används beräkningar för precision och recall samt för medelvärdet F-score. Resultatet visar att feltecknade ord ger upphov till feltaggningar, vilka det också finns fler av i andraspråkstexterna, liksom ordklasser som delar många ordformer. För övrigt visar sig inga anmärkningsvärda skillnader i verktygets precision mellan andraspråkstexter och texter i svenska.

    Earthquake Analysis Using a Migration Based Detection Algorithm Applied to Local Earthquake Data2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this study earthquake data is analyzed using a newly developed Migration Based Detection (MBD) algorithm (Wagner et al. 2017). A software environment suitable for manual analysis of large quantities of earthquakes (events) detected by the MBD algorithm is set up, and the MBD algorithm is applied to 13 days of seismic data from a network of 26 seismic stations in the geologically complex Hengill-area in southwest Iceland. A total of 859 event detections are produced and manually inspected. Out of these, 483 are considered true and/or uncertain, making the assessed number of false detections about 44%. A subset of 53 well defined true events are selected for event relocation using manual picking of first arrival P-waves. The relocation resulted in a mean difference of roughly 0.6 km for each coordinate in the horizontal plane and about 1.4 km in depth. Results of the study provide reference data that may aid further development of the MBD algorithm, as well as provide some insight into the performance of the MBD algorithm. The software environment tailored for analyzing events detected by the MBD algorithm may be used as a foundation for continued analysis of detected events.

    Improvement of RANS Forest Model via Closure Coefficient Modification2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    As wind farms continue to take up more land throughout Northern Europe, developers are looking to sparsely populated areas, particularly in northern Fennoscandia, which hosts strong winds but also mixed and patchy forests over complex terrain. The complexity makes wind resource assessments difficult, raising uncertainty and therefore cost. Computational fluid dynamics (CFD) has the potential to increase the accuracy and reliability of wind models, but the most common form of commercial CFD modeling, Reynolds averaged Navier-Stokes (RANS), makes limiting assumptions about the effect of the forest on the wind. The wind resource assessment and energy estimation tool WindSim® , developed by WindSim AS, utilizes a porous medium model of a homogeneous forest with the influence of the forest on the airflow as a drag force term in the momentum equations. This method has provided reliable wind speed results but has been less reliable in estimating turbulence characteristics. The measure we evaluate in this study is turbulence intensity (TI). In this investigation, we make two types of modifications to the model and evaluate their impact on the TI estimates by using a benchmark data set collected by Meroney [1]. The first method is a variable profile of leaf area index (LAI) to represent the physical shape of the forest more accurately, and the second is a series of modifications to the closure coefficients in the turbulence transport equations. These modifications focus on the work of Lopes et al. [2], who used a large eddy simulation (LES) model to show that the turbulence production terms originally proposed by Green [3], expanded upon by Sanz [4], and widely used in the industry are unnecessary. Our investigations found that the implementation of a variable LAI profile has a small but non-negligible effect and that the elimination of the production terms from the turbulence transport equations does lead to a significant reduction in TI immediately above the forest. Both methods have minor effects on wind speed estimates, but the modification of closure coefficients has a much more significant impact on the TI. The coefficients proposed by Lopes et al. [2] drastically reduce TI estimates, but the model is still unable to reflect the Meroney data throughout the forest. Continued modification to new closure coefficients in combination with a variable forest LAI and other modifications such as a limited length scale may lead to significant improvement in TI estimates in future models, but these modifications must be compared against real-world data to ensure their applicability.

    Omvårdnad av personer med diabetes i hemsjukvård2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie var att undersöka hur sjuksköterskor upplever omvårdnaden och den assisterade egenvården av personer med diabetes inskrivna inom hemsjukvården. I studien har elva sjuksköterskor anställda inom kommunal och privat hemsjukvård intervjuats. En kvalitativ innehållsanalys har använts för att analysera intervjutexterna. Analysen har resulterat i två teman och sex kategorier. Temat: ''Sjuksköterskans känsla av otillräcklighet'' bestod av tre kategorier;''Att uppleva brist på kunskap/utbildning'', ''att uppleva brist på stöd'',''att uppleva brist på riktlinjer och rutiner''. Temat: ''Sjuksköterskans upplevelse av känsla av otrygghet hos personer med diabetes''; ''Att sakna kontinuerlig vårdkontakt'', att sakna kunskap om sjukdomen'','' att behöva assisterad egenvård''. Resultatet visade att de intervjuade sjuksköterskorna upplevde diabetes som en komplex sjukdom med stort omvårdnadsbehov. De uppgav att de behövde mer kunskaper om sjukdomen, de kände sig otillräckliga. Vidare upplevde de intervjuade sjuksköterskorna att personerna med diabetes inte kände sig trygga, de saknade den kontinuerliga kontakten med diabetessjuksköterska som de tidigare haft när hemsjukvården sköttes av landstingen.

    The Sacred Pilgrimage: The Concept of Truth in the Life and Work of Lars Skytte2017Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis studies the life and work of Lars Skytte (1610-1696), a Swedish Ambassador to Portugal who converted to Catholicism and became a Franciscan theologian, in relation to the concept of Truth. For Skytte, Truth and Catholicism are synonymous. The thesis focuses on his semi-autobiographical book Peregrinatio sancta fratris Laurentii a D. P. Sueci (1658). As a sort of intellectual biography, this study aims at situating Skytte within the context of post- reformation rhetoric and theological thought. The main question guiding the thesis is in what way Lars Skytte argues for the Truth of the Catholic Church, as opposed to what he terms ‘schismatic’ and ‘heretical’ movements. Following a set of identified arguments for the Catholic Church as the religio vera, the thesis looks at how they are employed in various ways to answer the overarching question.

    Uncertainties Associated with Hydrological Terrain Analysis in Flat Topography Wetlands2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

     Describing how water flows in flat landscapes is generally difficult as the main driving force behind surface runoff is elevation differences. In an experiment designed to delineate the uncertainty in catchment areas created in software for geographical information systems (GIS), a flow algorithm that distributes the flow from one point to all of the neighbours with lower elevation was used. By analysing the values for the catchment areas created by this algorithm the uncertainty could be assessed. The main objective is therefore to investigate whether flow direction algorithms can be used to delineate uncertainty in catchment areas or not. The results acquired in this project consisted of area sizes for the different catchment areas connected to each wetland, as well as the distribution of values within these areas. The values signifies the percentage of each cell within an area that contributes to the drainage point. By relating the dispersion of values for certain thresholds to the size of the area, the main conclusion is that areas of small size are more affected by uncertainty.  Finally, some further studies within this area has been suggested. For example, to evaluate differences in runoff in different kinds of terrain, with different data resolutions or to correlate it to the effect of slope. In conclusion this project supplies an entrance to a new method of evaluating uncertainty in a field that surely can be broadened and repeated for greater accuracy.

    Bridging the Humanitarian-Development Divide: Indonesian-Swedish Stakeholder Case Studies on LRRD2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis studies the concept of Linking Relief, Rehabilitation and Development (LRRD), a topic discussed since the late 1980’s that has failed to be practically implemented, partly because of widely divergent perspectives on the concept. The discourse on LRRD has so far largely been conducted in a top-down fashion with donors constituting the dominant interlocutor, while the perspectives of aid organisations and local communities involved in humanitarian and developmental programmes have been widely overlooked. This thesis thus means to bring clarity to how LRRD is conceptualised by different stakeholders through proposing a comprehensive conceptual framework based from literature, which is used to analyse empirical case studies at the local, national, and international levels. The case studies were conducted in Indonesia and Sweden through interviews with 16 participants and a survey with 20 beneficiaries as respondents. The participants included: beneficiaries at a tsunami post-disaster site, local community leaders, a local level NGO, two national level Indonesia NGOs (MDMC and YEU), and an INGO (Plan International).The research reveal that none of the cases experienced as rigid divide between humanitarian and development action as is often suggested in the literature discourse and through donor policies. All interviewed NGOs expressed that they operated in a way that does create strong humanitarian-developmental linkages and that the major obstacle to achieve this is external pressures, particularly from donor agencies, to operate under exclusively humanitarian or developmental imperatives.

    Pulmonary rehabilitation in COPD - available resources and utilization in Swedish primary and secondary care2017In: The International Journal of Chronic Obstructive Pulmonary Disease, ISSN 1176-9106, E-ISSN 1178-2005, Vol. 12, 1695-1704 p.Article in journal (Refereed)
    Abstract [en]

    Introduction: Pulmonary rehabilitation is effective in all stages of COPD. The availability and utilization of pulmonary rehabilitation resources, and the characteristics of COPD patients receiving rehabilitation, were investigated in primary and secondary care in central Sweden. Materials and methods: Data on available pulmonary rehabilitation resources were collected using questionnaires, to 14 hospitals and 54 primary health care centers, and information on utilization of different rehabilitation professionals was obtained from questionnaires completed by 1,329 COPD patients from the same centers. Multivariable logistic regression examined associations with having received rehabilitation in the previous year. Results: In primary care, nurse- based asthma/COPD clinics were common (87%), with additional separate access to other rehabilitation professionals. In secondary care, rehabilitation was more often offered as part of a multidisciplinary teamwork (71%). In total, 36% of the patients met an asthma/COPD nurse in the previous year. Utilization was lower in primary than in secondary care for physiotherapists (7% vs 16%), occupational therapists (3% vs 10%), nutritionists (5% vs 13%), and counselors (1% vs 4%). A higher COPD Assessment Test score and frequent exacerbations were associated with higher utilization of all rehabilitation professionals. Conclusion: Pulmonary rehabilitation resources are available but underutilized, and receiving rehabilitation is more common in severe COPD. Treatment recommendations need to be better implemented, especially in mild and moderate COPD.

    Folate intake in a Swedish adult population: Food sources and predictive factors2017In: Food & Nutrition Research, ISSN 1654-6628, E-ISSN 1654-661X, Vol. 61, no 1, 1328960Article in journal (Refereed)
    Abstract [en]

    Introduction: Folate plays an important role in cell metabolism, but international studies show that intake is currently below recommendations, especially among women. The study objective was to identify folate food sources by food group, gender, and age group, and to identify factors influencing folate intake, based on food consumption data for Swedish adults in the 2010-11 Riksmaten study.

    Methods: The sample included a representative Swedish population aged 18-80 years (n = 1657; 56.3% female). Food and nutrient intakes were estimated from self-reported food records during 4 consecutive days. Food consumption was categorized into 26 food groups. Stepwise regression was used to analyze food groups as folate sources for participants. Factors predicting the highest folate intake (third tertile) were determined by logistic regression analysis.

    Results: Vegetables and pulses represented the most important folate source for all age groups and both genders, especially in women aged 45-64 years (49.7% of total folate intake). The next folate source in importance was dairy products for the youngest group (18-30 years), bread for men, and fruit and berries for women. The likelihood of being in the highest tertile of folate intake (odds ratio = 1.69, 95% confidence interval 1.354-2.104) was higher for men. Influencing factors for folate intake in the highest tertile were low body mass index and high educational level in the men, and high educational level, vegetarian diet, organic product consumption, nonsmoking, and alcohol consumption within recommendations in the women.

    Conclusion: This study describes the folate intake per food group of Swedish adults according to the 2010-11 Riksmaten survey, identifying vegetables and pulses as the most important source. Data obtained on factors related to folate consumption may be useful for the development of specific nutrition education programs to increase the intake of this vitamin in high-risk groups.

    Luminosity determination in pp collisions at root s=8 TeV using the ATLAS detector at the LHC2016In: European Physical Journal C, ISSN 1434-6044, E-ISSN 1434-6052, Vol. 76, no 12, 653Article in journal (Refereed)
    Abstract [en]

    The luminosity determination for the ATLAS detector at the LHC during pp collisions at s√= 8 TeV in 2012 is presented. The evaluation of the luminosity scale is performed using several luminometers, and comparisons between these luminosity detectors are made to assess the accuracy, consistency and long-term stability of the results. A luminosity uncertainty of δL/L=±1.9% is obtained for the 22.7fb−1 of pp collision data delivered to ATLAS at s√= 8 TeV in 2012.

    Increased levels of alveolar and airway exhaled nitric oxide in runners2017In: Upsala Journal of Medical Sciences, ISSN 0300-9734, E-ISSN 2000-1967, Vol. 122, no 2, 85-91 p.Article in journal (Refereed)
    Abstract [en]

    Aim: The objective of this study was to apply extended NO analysis for measurements of NO dynamics in the lung, divided into alveolar and airway contribution, in amateur runners and marathoners. Methods: The athletes participated in either a marathon or a half marathon. The athletes self-reported their age, weight, height, training distance per week, competing distance, cardio-pulmonary health, atopic status, and use of tobacco. Measurements of exhaled NO (FENO) with estimation of alveolar NO (CANO) and airway flux (J(aw)NO), ventilation, pulse oximetry, and peak flow were performed before, immediately after, and 1hour after completing the race. Results: At baseline the alveolar NO was higher in amateur runners, 2.91.1ppb (p=0.041), and marathoners, 3.6 +/- 1.9ppb (p=0.002), than in control subjects, 1.4 +/- 0.5ppb. J(aw)NO was higher in marathoners, 0.90 +/- 0.02 nLs(-1) (p=0.044), compared with controls, 0.36 +/- 0.02 nLs(-1), whereas the increase in amateur runners, 0.56 +/- 0.02 nLs(-1), did not attain statistical significance (p=0.165). Immediately after the race there was a decrease in FENO in both amateur runners and marathoners, whereas CANO and J(aw)NO were decreased in marathoners only. Conclusion: Our results support the view that there is an adaptation of the lung to exercise. Thus strenuous exercise increased both airway and alveolar NO, and this might in turn facilitate oxygen uptake.

    Om en god livskvalité kunde uppnås hos patienter med kronisk hjärtsvikt, en koppling mellan strukturerade träningsprogram och vikten av egenvård: - En litteraturstudie2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    BakgrundKronisk hjärtsvikt är idag en folkhälsosjukdom vilket vanligtvis drabbar den äldre generationen som i sin tur påverkar både patienter, anhöriga men även samhället med stora sjukvårdskostnader. Fysisk aktivitet har visat sig ge positiva effekter hos personer med hjärtsvikt gällande morbiditet, livskvalité samt fysisk kapacitet.

    Syfte: Syftet med litteraturstudien var att undersöka om en förbättrad livskvalité kunde uppnås med egenvård inriktad mot fysisk aktivitet.

    Metod: Litteraturstudie, 11 randomiserade kontrollerade studier från databaserna PubMed och Cinahl.

    Resultat: Resultatet presenterades utifrån litteraturstudiens två frågeställningar som berörde olika träningsprogram med fokus på fysisk aktivitet samt egenvårdshantering och livskvalité hos patienter med kronisk hjärtsvikt. Resultatet visade att strukturerade träningsprogram gav en ökad fysisk prestationsförmåga i interventionsgrupperna efter programmens slut. Det fanns även ett samband mellan den förbättrade prestationsförmågan och undervisningen vilket innebar stöttning och utbildning hur patienterna kunde uppnå ett bättre resultat under träningsperioden. Genom utbildning, information och rådgivning kunde patienterna förbättra sin egenvårdshantering genom att få insikt om sin sjukdom och kunde därmed identifiera tidiga tecken på försämring av symtomen vilket i sin tur resulterade i en bättre livskvalité efter interventionens slut. Genom ett gruppbaserat egenvårdsprogram vilket baserades på att deltagarna skulle utbyta erfarenheter och få ökad kunskap om sin sjukdom från varandra uppnåddes en bättre egenvård, dock inte en ökad livskvalité.

    Slutsats: Det framgår att olika former av strukturerade träningsprogram kan öka den fysiska prestationsförmågan hos patienter med kronisk hjärtsvikt. Genom att patienten utövar någon form av fysisk aktivitet som en egenvårdsåtgärd kan det resultera till en förbättrad fysisk prestationsförmåga samt en ökad livskvalité. Gällande vilken typ av fysisk aktivitet som är den mest effektivaste metoden kan dock inte fastslås och det behövs mer omfattande forskning inom området.

    Multi-Criteria Decision Analysis in Wind power Project Development: Case study in Latvia2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Wind Power Project Development is a complicated, capital and resource-inclusive process, where a wide variety of factors have to be considered and several stakeholders have a significant say in the process. Decision making in such an environment is complex and has to be approached comprehensively. In order to sustain a structured and clear decision-making process, the sustainable energy industry has recognized Multi-Criteria Decision Analysis (MCDA) method as a suitable set of tools to aid in the decision-making process. One of the MCDA tools – PROMETHEE II, has been examined in this master thesis, to evaluate its eligibility as a decision making aid in wind power project development.

    To structurally and realistically evaluate the tool, it has been applied to a case study in Ventspils region, in Latvia. The author of this thesis has a preliminary agreement with the owners of the sites to develop the project, therefore, this thesis has a strong potential for a practical implementation in future. Four scenarios have been developed for an evaluation, contributing to four variations of the different amount of turbines erected, with two different hub heights, on two differently sized sites. The scenarios are assessed based on the interests of six key stakeholders. Their opinion on twelve criteria is examined.

    Input data for each criterion has been generated via WindPro and MS Excel software or by authors assessment based on the researched literature. PROMETHEE II is used to extrapolate a comprehensive and clear representation of the results.

    The evaluation of the MCDA method proved that MCDA tools, and PROMETHEE II, in particular, can provide excellent support in decision making in wind power development. A wide variety of input data, as well as the various and often contradicting interests by different stakeholders, can be taken into account, while, at the same time, a clear result that can assist in decision making, is generated.

    Educating the gamer.: An analysis on how the “gamer” is taught the rules of a game efficiently to recognize patterns and become a better player.2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this thesis, the question of immersion and learning in tutorials is examined to find whether there are principles of design that can universally form a tutorial of a high quality according to several predetermined traits. A formal analysis of the tutorials for three specified games are conducted to identify the underlying principles of design that govern the structure for each individual tutorial. The resulting analyses are then compared to each other to reveal similarities between the tutorials so that the principles of design can be identified and examined. The findings point to no universal principles of design that will generate a tutorial of high quality, instead, the utilization of these principles is angled towards the specific needs of the game being developed.

    What About Poverty?: A multidimensional approach to the poverty focus of Swedish bilateral aid2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study examines the poverty focus of Swedish bilateral aid and if a multidimensional poverty measure has an effect on the selection of Swedish strategy countries within Sida’s bilateral aid program. Sweden, while generally seen as an altruistic donor, has been noted to allocate resources to relatively richer countries as a result of its wider aim with ODA such as democratic progress and human rights protection. To analyze the relationship between Swedish bilateral aid and poverty, we use concentration curves and a logistic regression for the year of 2016 for Sweden’s strategy countries. The regressions are performed using two measures of poverty, the Multidimensional Poverty Index and extreme monetary poverty (1.9$/day), controlling for institutional and strategic factors. The results for Sweden’s bilateral aid program show a slight poverty focus in terms of multidimensional poverty, as well as tendencies to focus on consistency, geopolitics and comparative advantages. There is no significant relationship between strategy countries and degree of monetary poverty. The results are largely aligned with Swedish policy objectives.

    Kan en Phillipskurva med förankrade inflationsförväntningar och korttidsarbetslöshet förklara inflationen i Sverige?2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Under senare år har såväl forskare som centralbanker observerat att sambandet mellan inflation och arbetslöshet förfaller försvagat. Två uppmärksammade förklaringar till det försvagade sambandet är att inflationsförväntningar blivit förankrade vid centralbankers inflationsmål samt att korttidsarbetslöshet har en större betydelse för lönebildning än total arbetslöshet. Ball och Mazumder (2014) kombinerar dessa förklaringar och finner att en Phillipskurva med förankrade inflationsförväntningar och korttidsarbetslöshet bättre förklarar inflationen i amerikansk ekonomi än en traditionell Phillipskurva mellan 2000K1-2014K3. På basis av data för viktad medianinflation från Riksbanken och arbetslöshet från Statistiska centralbyrån visar denna studie att Ball och Mazumders (2014) resultat inte kan replikeras på svensk ekonomi. Resultatet indikerar att inflationsförväntningarna i Sverige inte är helt förankrade samtidigt som gruppen korttidsarbetslösa endast har en marginellt större betydelse än total arbetslöshet för inflationen. Detta kan tänkas bero på att förtroendet för Riksbankens inflationsmål minskat och på att arbetsmarknadspolitiska åtgärder gör att även gruppen långtidsarbetslösa har betydelse för lönebildningen i Sverige.

    Abstract [en]

    This article is discusses the problem concerning the lack of knowledge about Sámi archaeology and history.  One important base for our knowledge, the ancient monuments, have not been sufficiently surveyed, documented and analysed. This situation is a consequence of old Social Darwinist ideas of the Sámi as a people without history, as well as a remaining nationalistic bias where Swedish archaeology is the norm.

    The article deals with the threats to the Sámi cultural heritage, which, if not surveyed and registered, is likely to be destroyed by current forestry practices as well as other types of exploitations.

    While most of southern Sweden has been subject for both primary and secondary survey for ancient monuments by the National Board of Antiquities until it was mainly finished 1996 (2001), most of Sámi territories have not been surveyed at all.

     A case study from Gállok outside Jokkmokk, where a mine is planned in an earlier Forest Sámi ”skatteland” (‘ Lap/Sami tax land’ ), threatening the cultural heritage, illustrates the problems mentioned in detail.

    The impact of stellar magnetic activity on the radial velocity search of exoplanets2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Radial velocity measurements are critical in finding and confirming exoplanets. To confine the parameters of the planet we naturally want to minimise the errors on the measurement. However the observed measurement error is now on the same order as the precision of the instrument. This so called jitter is related to the stellar activity (Wright 2005), i.e. the magnetic field of the star. In this paper we investigate if we can discover any correlation between the radial velocity variation and the magnetic activity of the star using HARPSpol spectra for the two stars Epsilon Eridani and GJ674.

    Malingsbo Herrgård: Energiberäkningar och åtgärdsförslag för en karolinsk 1700-talsgård2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Malingsbo Estate is a 18th century wooden building located in the small village of Malingsbo. Through the years, the estate has had a wide variation of usages. Today, almost 70 years since the last major renovation it is being utilized 6 weeks per year.

     

    The following report, which has been made possible with the cooperation with the National Property Board (Statens Fastighetsverk) seeks to answer the following four questions. 1: What is the current climate inside the building 2: What are the resident’s views on the climate and the status of the building. 3: suggestions on how to, with the current building increase the period in which the inside climate is suitable for living. 4: Suggestions for lowering the energy usage for the building. These four points seeks to be answered with the following method: reports from Statens Fastighetsverk, surveys, field excursions and simulations in VIP-Energy.

     

    The result of this report which should be especially considered is the following: At present time with no heating in the building, residents feel the climate during July to be acceptable to good, while during October most thinks it is to cold. For increasing the duration where the building meets a temperature of 20 degrees Celsius to 24 weeks’ installations of a 12500 W heating system is needed. For lowering the energy consumption without making large changes to the building two options should be specially considered: Insulation in the foundation with 50 mm insulation, and installation of window shutters during week 45 to 10. A larger installation suitable is solar panels for heating.

    High-ET isolated-photon plus jets production in pp collisions at √s=8 TeV with the ATLAS detector2017In: Nuclear Physics B, ISSN 0550-3213, E-ISSN 1873-1562, Vol. 918, 257-316 p.Article in journal (Refereed)
    Abstract [en]

    The dynamics of isolated-photon plus one-, two- and three-jet production in pp collisions at a centre-of-mass energy of 8 TeV are studied with the ATLAS detector at the LHC using a data set with an integrated luminosity of 20.2 fb-1. Measurements of isolated-photon plus jets cross sections are presented as functions of the photon and jet transverse momenta. The cross sections as functions of the azimuthal angle between the photon and the jets, the azimuthal angle between the jets, the photon-jet invariant mass and the scattering angle in the photon-jet centre-of-mass system are presented. The pattern of QCD radiation around the photon and the leading jet is investigated by measuring jet production in an annular region centred on each object; enhancements are observed around the leading jet with respect to the photon in the directions towards the beams. The experimental measurements are compared to several different theoretical calculations, and overall a good description of the data is found.

    Detection and characterization of Brucella spp. in bovine milk in small-scale urban and peri-urban farming in Tajikistan2017In: PLoS Neglected Tropical Diseases, ISSN 1935-2727, E-ISSN 1935-2735, Vol. 11, no 3, e0005367Article in journal (Refereed)
    Abstract [en]

    Brucellosis is one of the most common zoonoses globally, and Central Asia remains a Brucella hotspot. The World Health Organization classifies brucellosis as a neglected zoonotic disease that is rarely in the spotlight for research and mainly affects poor, marginalized people. Urban and peri-urban farming is a common practice in many low-income countries, and it increases the incomes of families that are often restrained by limited economic resources. However, there is a concern that the growing number of people and livestock living close together in these areas will increase the transmission of zoonotic pathogens such as Brucella. This study investigates the presence of Brucella DNA in bovine milk in the urban and peri-urban area of Dushanbe, Tajikistan. Brucella DNA was detected in 10.3% of 564 cow milk samples by IS711-based real-time PCR. This finding is concerning because consumption of unpasteurized dairy products is common in the region. Furthermore, Brucella DNA was detected in the milk of all seropositive cows, but 8.3% of the seronegative cows also showed the presence of Brucella DNA. In addition, sequence analysis of the rpoB gene suggests that one cow was infected with B. abortus and another cow was most likely infected with B. melitensis. The discrepancies between the serology and real-time PCR results highlight the need to further investigate whether there is a need for implementing complementary diagnostic strategies to detect false serological negative individuals in Brucella surveillance, control, and eradication programmes. Furthermore, vaccination of cattle with S19 in addition to vaccination of small ruminants with Rev 1 might be needed in order to control Brucella infections in the livestock population but further research focusing on the isolation of Brucella is required to obtain a comprehensive understanding of the Brucella spp. circulating among the livestock in this region.

    Mating Changes Sexually Dimorphic Gene Expression in the Seed Beetle Callosobruchus maculatus2017In: Genome Biology and Evolution, ISSN 1759-6653, E-ISSN 1759-6653, Vol. 9, no 3, 677-699 p.Article in journal (Refereed)
    Abstract [en]

    Sexually dimorphic phenotypes arise largely from sex-specific gene expression, which hasmainly been characterized in sexually naive adults. However, we expect sexual dimorphism in transcription to be dynamic and dependent on factors such as reproductive status. Mating induces many behavioral and physiological changes distinct to each sex and is therefore expected to activate regulatory changes in many sex-biased genes. Here, we first characterized sexual dimorphism in gene expression in Callosobruchus maculatus seed beetles. We then examined how females and males respond to mating and how it affects sex-biased expression, both in sex-limited (abdomen) and sex-shared (head and thorax) tissues. Mating responses were largely sex-specific and, as expected, females showed more genes responding compared with males (similar to 2,000 vs. similar to 300 genes in the abdomen, similar to 500 vs. similar to 400 in the head and thorax, respectively). Of the sex-biased genes present in virgins, 16%(1,041 genes) in the abdomen and 17%(243 genes) in the head and thorax altered their relative expression between the sexes as a result of mating. Sex-bias status changed in 2% of the genes in the abdomen and 4% in the head and thorax following mating. Mating responses involved de-feminization of females and, to a lesser extent, de-masculinization of males relative to their virgin state: mating decreased rather than increased dimorphic expression of sex-biased genes. The fact that regulatory changes of both types of sex-biased genes occurred in both sexes suggests that male-and female-specific selection is not restricted to male-and female-biased genes, respectively, as is sometimes assumed.

    Framtidens elnät: En studie över hur olika framtidsscenarionpåverkar elnätskundens ekonomiska förutsättningar2017Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In association with Sweco Energuide, two different futurescenarios have been developed regarding how the power gridcustomers might use the power grid in 10 years. In the firstscenario, scenario high load, the customers will not use anyenergy storage or load management. As a result their power demandwill increase drastically. If the customers act as in the secondscenario, scenario low load, they will see the potential ininvesting in energy storage and load management to reduce theirpower grid costs. The study has explored the economic incentivesto invest in scenario low load, which factors will affect thechoice of scenario low load and what will push the customers tochoose between the scenarios.The purpose of the study has been fulfilled by hearing theexperts’ prognosis for the future and doing a net present valueanalysis to examine the economic incentives. Power grid companieswill charge the maximal power output and if the customer do notmake any active choices it will lead to higher electrical costs.The economic incentives are mainly dependent on which choices thecustomers make regarding how the car is charged. By choosing lowercharge power and by consuming the power during time periods withlower electrical costs the customer can find incentives to act asscenario low load. If there is a time dynamic tariff theincentives increases. Even though the battery technologies andload management techniques are constantly developed the costs aretoo high and reduce the profitability of scenario low load.

    Tillståndsprövningen vid vägbyggen enligt 7 kap. 29 a § MB2017Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    För att ett vägbygge ska bli aktuellt måste tillstånd för olika åtgärder sökas och ges i enlighet med väglagen (1971:948) och miljöbalken (1998:808). För tillstånd krävs att lagstiftningens miljökrav uppfylls.

    Visar det sig däremot att det kan finnas en risk för en betydande miljöpåverkan på särskilda skyddsområden enligt art- och habitatdirektivet eller fågeldirektivet, (nedan kallat Natura 2000-områden) ska enligt 7:28 a MB tillstånd först ges för att ett projekt ska få komma till stånd. Regleringen i 7 kap. MB härstammar från fågeldirektivet och art- samt habitatdirektivet, vilket är till för skyddet av den biologiska mångfalden inom EU. Prövningen föregås av en miljökonsekvensbeskrivning (nedan kallad MKB) där särskilda krav ställs på Natura 2000-bedömningen enligt direktiven samt MKB-direktivet. MKB utgör beslutsunderlag för tillståndsprövningen och länsstyrelsen ska bedöma om projektet utifrån det ändå kan tillåtas om föreskrivna villkor kan se till att en betydande miljöpåverkan inte uppstår.

    Praxis har belyst regleringen av tillståndsprocesserna och efter Bungefallet har synen förändrats. Innan fallet kunde verksamhetsutövare se regeringens tillåtlighetsbeslut som ett "grönt ljus" för projektet. Nu hänvisade HD till EU-rättens krav om "en fullständig, exakt och slutgiltig bedömning"2 av hela projektets miljöpåverkan som ska ske på Natura 2000-området. De belyste även rättskraften av regeringens tillåtlighetsbeslut och att den inte hindrar att den samlade bedömningen kan komma att göras även i senare led och innebära att ett tillåtlighetsbeslut inte ger ett grönt ljus likt innan till projektet. HFD har vidare efter två domar belyst regleringen i 4:8 MB i samband med att regeringen hade gett projekten tillåtlighet. Regleringen i 4:8 MB säger att användning av mark eller vatten inte får komma tills stånd om tillstånd enligt 7:28 a MB krävs. Tillstånd måste enligt paragrafen först ges för Natura 2000-området innan en vägplan kan antas enligt väglagen. 4 Här menar HFD på att i ett fall inte spelar någon roll när den samlade bedömningen sker i tillståndsprocesserna så länge den sker i något skede. I den andra domen säger HFD att hela projektets påverkan ska göras så tidigt som möjligt genom en samlad bedömning.

    Uppsatsen tar upp för- samt nackdelar med att tillståndsprövningen av Natura 2000-området kommer först eller senare i den samlade tillståndsprocessen. Eftersom MKB utgör beslutsunderlag besvaras frågan om den kan utgöra en avgörande roll i processen.

    Analys av egenfrekvenser och laster för en vertikalaxlad, skruvad Savoniusturbin: slutsatser om möjliga materialval och geometrierför att undvika resonans2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    At the Division of Electricity at Uppsala university a project isconducted to develop a smaller wind turbine for conditions in theAntarctica. This is a part of a larger, international researchproject in the field of particle physics known as the Ariannaexperiment. The project consists of developing and installing avertical axle wind turbine of screwed Savonius type. A prototypeof this has been manufactured and installed 2016 in Antarctica forinitial testing and measurement.Wind turbines are subjected to complex and varied loads from windand rotation which gives rise to cyclical strain. The rotor bladesare particularly vulnerable, which imposes high material andconstruction requirements to avoid fatigue and failure, whichoften is caused by vibrations and oscillations. Vibrations can becharacterized in terms of the natural frequencies witch in shortmeans that the system, at specific frequencies, tend to oscillatewith increasing amplitude and at worst, resonate if these areexcited. How a complex design will behave by external periodicinterference is complicated to calculate analytically. Naturalfrequencies are therefore most often calculated using FEM-methodsand computer simulations.The aim of this thesis is to study how oscillating forces interactwith the natural frequencies and rotational loads for a specificSavonius wind turbine. How these are influenced by engineering,design and material selection. The goal is to draw conclusionsabout design and possible materials selection to avoid unnecessaryvibrations. Without this analysis, there is a risk of increasedwear and damage to the structure.The project includes such analysis of two different sizes of theSavonius turbine. A small 200x400 mm and a larger 1000x2000 mm.To understand the problem, a preliminary study of basic harmonicoscillation, strength of materials and of the existing prototypewas made. Following a requirement specification, somedelimitations were made so that the simulations would not be tooextensive. Subsequently, a minor design work was done to obtain 13different configurations of the turbine for simulation using FEM-methods.The result showed that none of the turbines rotational frequenciesis close to the turbine’s natural frequencies. However, accountmust be taken of cogging frequencies in the generator. These arewithin the range of the design's natural frequencies.All simulations of centrifugal force found that there isrelatively little tension at the selected maximum speed of 660 and132 revolutions per minute. However, as the results showed thatthe plates which are mounted between the rotor blades to providestability, creates greater stresses in the structure than thosewithout. Two proposals for the configuration of turbines have beenpresented in the report.

    Passive in-vehicle driver breath alcohol detection using advanced sensor signal acquisition and fusion2017In: Traffic Injury Prevention, ISSN 1538-9588, E-ISSN 1538-957X, Vol. 18, S31-S36 p.Article in journal (Refereed)
    Abstract [en]

    Objective: The research objective of the present investigation is to demonstrate the present status of passive in-vehicle driver breath alcohol detection and highlight the necessary conditions for large-scale implementation of such a system. Completely passive detection has remained a challenge mainly because of the requirements on signal resolution combined with the constraints of vehicle integration. The work is part of the Driver Alcohol Detection System for Safety (DADSS) program aiming at massive deployment of alcohol sensing systems that could potentially save thousands of American lives annually.

    Method: The work reported here builds on earlier investigations, in which it has been shown that detection of alcohol vapor in the proximity of a human subject may be traced to that subject by means of simultaneous recording of carbon dioxide (CO2) at the same location. Sensors based on infrared spectroscopy were developed to detect and quantify low concentrations of alcohol and CO2. In the present investigation, alcohol and CO2 were recorded at various locations in a vehicle cabin while human subjects were performing normal in-step procedures and driving preparations. A video camera directed to the driver position was recording images of the driver's upper body parts, including the face, and the images were analyzed with respect to features of significance to the breathing behavior and breath detection, such as mouth opening and head direction.

    Results: Improvement of the sensor system with respect to signal resolution including algorithm and software development, and fusion of the sensor and camera signals was successfully implemented and tested before starting the human study. In addition, experimental tests and simulations were performed with the purpose of connecting human subject data with repeatable experimental conditions. The results include occurrence statistics of detected breaths by signal peaks of CO2 and alcohol. From the statistical data, the accuracy of breath alcohol estimation and timing related to initial driver routines (door opening, taking a seat, door closure, buckling up, etc.) can be estimated.The investigation confirmed the feasibility of passive driver breath alcohol detection using our present system. Trade-offs between timing and sensor signal resolution requirements will become critical. Further improvement of sensor resolution and system ruggedness is required before the results can be industrialized.

    Conclusions: It is concluded that a further important step toward completely passive detection of driver breath alcohol has been taken. If required, the sniffer function with alcohol detection capability can be combined with a subsequent highly accurate breath test to confirm the driver's legal status using the same sensor device. The study is relevant to crash avoidance, in particular driver monitoring systems and driver-vehicle interface design.

    The Authorised OECD Approach and the Attribution of Profit to Banks´PEs: How far is the functionally separate entity approach fully achievable?2017Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis´ aim is to analyse the extension of the fuctionally separate entity approach  (FSEA) used in order to attribute a proper amount of profit to banks´ permanet establishment (PE) and the related implication in the authorised OECD approach (AOA). From a general perspective in fact, under the FSEA a PE is treated as being a separate entity from the head office, functions, assets, risks and funding shall be attributed as it was a separate legal entity. However, beyond the previous statement some general limitation of the FSEA and the particular nature of bank (and in general financial institutions) require a further reflection. Practically speaking: how far is the extension of this functional separate entity approach? Is it treatable as a complete separate company by itself? If not, how far is from the economic reality of the company? After a fisrt descriptive part, the author analysis the hybrid nature of the FSEA: acoording with his view traces of single entity approach are founded. However the hybrid nature of the FSEA is not per se a limitation but shall be considered as strength: the OECD´s approach grants a certain degree of flexibility and ability to adapt based on the context that on the other hand would have let the FSEA and the AOA be even more complicate.

    Distributed ledger technology in the capital market: Shared versus private information in a permissioned blockchain2017Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This master thesis explores how blockchain technologies can be utilized within the financial sector with focus on how to store both private and public information on the blockchain. The capital market is looking into ways of cutting down administrative work through streamlining the financial process by using blockchain technologies. Public key encryption together with hash functions and a consensus mechanism make up the basis for creating a shared trustless database system. The thesis was conducted by extensive research concerning cryptographic topics, and a literature study was made to compare existing solutions. This was done in order to come up with a new design which suggests how to utilize blockchain technologies in order to create private transactions. The design solves issues regarding key management and how to handle both private and public information on the blockchain. The proposed design is an extension of Visigon's existing permissioned blockchain, and it introduces different roles within the peer to peer network as well as a concept of having regulating nodes that together with the involved bank's nodes handle the process of private transactions. Private transactions are encrypted by using symmetric keys and thereafter recorded on the blockchain. In conclusion blockchain technology might not be the most suitable database system for banks to keep transactions private. Future solutions should consider the best attributes of blockchain technologies and create a new system with the single purpose of being a tool for the financial market.

    Equal clinical performance of a novel point-of-care cardiac troponin I (cTnI) assay with a commonly used high-sensitivity cTnI assay2017In: Clinica Chimica Acta, ISSN 0009-8981, E-ISSN 1873-3492, Vol. 469, 119-125 p.Article in journal (Refereed)
    Abstract [en]

    Background: Efficient rule-out of acute myocardial infarction (MI) facilitates early disposition of chest pain patients in emergency departments (ED). Point-of-care (POC) cardiac troponin (cTn) may improve patient throughput. We compared the diagnostic accuracy of a novel cTnI test (Minicare cTnI, Philips), with current POC cTnI (I-Stat, Abbott) and high-sensitivity central laboratory cTnI (hs-cTnI; Architect, Abbott) assays.

    Methods: The clinical performance of the assays were compared in samples from 450 patients from a previous clinical evaluation of Minicare cTnI.

    Results: Minicare cTnI correlated with Architect hs-cTnI (r(2) = 0.85, p < 0.0001) and I-Stat cTnI (r(2) = 0.93, p < 0.0001). Areas under the receiver operating characteristics curves were 0.87-0.91 at admission (p = ns) and 0.96-0.97 3 h after admission (p = ns). The negative predictive values (NPV) at admission were 95% ((92-97%, 95% CI) for Minicare cTnI and increased to 99% (97-100%) at 2-4 h, and similar to Architect hs-cTnI (98%, 96-100%), but higher than I-Stat cTnI (95%, 92-97%; p < 0.01). Negative likelihood ratios (LR) after 2-4 h were 0.06 (0.02-0.17, 95% CI) for Minicare cTnI, 0.11 (0.05-0.24) for Architect hs-cTnI (p = 0.02) and 0.28 (0.18-0.43) for I-Stat cTnI (p < 0.0001). The clinical concordances between Minicare cTnI and Architect hs-cTnI were 92% (admission) and 95% (2-4 h), with lower concordances between Minicare cTnI and I-Stat cTnI (83% and 78%, respectively; p = 0.007).

    Conclusions: The Minicare cTnI POC assay may become useful for prompt and safe ruling-out of AMI in ED patients with suspected AMI using a guideline supported 0/3 h sampling protocol.

    Undersökning av lönsamhet för batterilagring i kommersiella fastigheter tillsammans med solceller: Förutsättningar för lönsamhet vid optimal drift och vid drift baserad på prognoser2017Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The majority of the existing photovoltaic (PV) systems are dimensioned in such a way that no or only a small part of the production exceeds the buildings internal consumption. This is done because sold electricity to the grid has a lower economic value than if used internally in the building. Therefore commercial buildings, with high consumption during sunny hours, are to prefer when installing PV.

    Implementing a battery energy storage system in these facilities can lead to higher self consumption of the PV energy and reduced electricity bills. To take full advantage of this potential it requires optimal management of the battery. In this study an optimized battery algorithm was developed to show the full potential a perfectly managed battery can have to reduce cost of electricity within commercial buildings.

    There are three main charge and discharge patterns for a battery which can reduce the cost on the electricity bill: 1) Charge and discharge at different prices, 2) peak shaving and 3) overproduced PV is stored for later use. By utilizing a battery in an optimal way to reduce the costs as much as possible, batteries will reach break even at battery prices between 1350-2100 SEK/kWh, depending on which scenario evaluated.

    By implementing forecast based desicion-making, in which the battery operation is optimized with respect to PV and consumption forecasts, the system profitability declines rapidly, especially when using a consumption forecast. A real system would probably profit from basing the battery operation on both forecasts and real time measurements.

    Uttorkning av högpresterande betonggolv: Råd och rekommendationer vid mätning av RF2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A development project was undertaken within the consortia formed by Polygon and AK-konsult. The aim of this project was to map out the impact of humidity leakages on the result of humidity measurements in concrete slabs according to the so-called RBK-method. It is behind the idea of this development project that the main purpose of this thesis can be derived from. For instance, an evaluation of already existing data material from a RBK-measurement has been done. A method has been retrieved in order to compare the trend of the measured values of the relative humidity with the trend of the expected values of the relative humidity during the drying process. The main goal has been to implement this method as an instrument to analyze the actual drying process.

    A survey study was undertaken among the employees of the consortia in order to point out the differences that arise during the installation of the measurement equipment prior to measurement according to the RBK-method. The result of the survey has been summarized and analyzed in purpose to catch a wider glimpse over the different kinds of variables that might have an impact on the result from a RBK-measurement.

    The outcome from the study of the existing measurement data shows that some of the measurement spots tends to dry out faster than the calculated drying process, while other spots indicates a slower drying process. Three of them actually pointed out that they were under humidity, which implies that they still hadn’t reached the stadium of moisture equilibrium with the concrete. The main reason behind the observed discrepancies might have its explanation in the fact that measurement wholes that have been subjected to a big humidity leakage. The consequence of measurement spots subjected to big humidity leakages, is that the measured value of the relative humidity turns out to be much lower than the actual level of the relative humidity in the concrete.

    An observation has been made in the plausibility analysis and in the Vaisalaproject that the normative equilibrium time exceeds the number of three days that’s been ordained by RBK. A further study of the normative equilibrium time can thereby be recommended to clarify if it still can be compatible with the different kinds of concrete classes of today.

    Non-Linear Latent Variable Models: A Study of Factor Score Approaches2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Non-linear latent variable models are associated with problems which are difficult to handle in applied sciences. Four methods for estimating factor scores, with the purpose of estimating latent variable models with an interaction term, were investigated. The LISREL procedure provided inconsistent estimates of the interaction term for all sample sizes and distributions of the latent exogenous variables. The Bartlett-Thompson approach yielded consistent estimates only when the distribution of the latent exogenous variables was normal, whereas the Hoshino-Bentler and adjusted LISREL approaches yielded consistency for all distributions of the latent exogenous variables. In the Bartlett-Thompson and LISREL approaches the interaction term is formed from multiplying latent variable scores, whereas in the Hoshino-Bentler and adjusted LISREL approaches the interaction term is treated as yet another factor which is freely estimated. It was, hence, concluded that the methods treating the interaction term as a factor were more appropriate (in terms of consistency and robustness) than those using products of factor scores for estimating the latent variable model.

    Comparing the Period-Luminosityrelationships in variable stars2017Student paper other, 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    There are four Period Luminosity relations from three sources, [3, 5, 9, 11], that are compared for theiraccuracy in calculating distances and to see how much uncertainty has to be considered when calculatingother distances based on these. Here, the relations are compared by using each to calculate and compare thedistances of the stars: BK Vir, L2 Pup, R Hor, R Hya, R Lep, and RR Aql; along with using data from AAVSOand SIMBAD in the calculations. The relations have an uncertainty that ranges from about 30%-40%, exceptfor the relation from [9] that has an uncertainty of 90%

    Abstract [en]

    The work is being carried out with the construction company Arcona.The aims are to evaluate and make recommendations about theirbuilding logistics solution CSL. For now, CSL is only used forprojects in Stockholm. If a need for CSL occurs in Uppsala, it willalso be introduced there.The purpose of the study is to investigate how CSL works inStockholm, what good experiences and challenges identified by theusers in Stockholm. Another purpose is to identify which partfunctions of the logistics solution that are requested by futureusers in Uppsala.To find out how the solution works today on projects in Stockholm,three qualitative interviews have been conducted. To find out aboutthe expectations of subcontractors (UE) on a logistics solution inUppsala, a qualitative interview has been conducted with asubcontractor. All interviews were then encoded to find themes andsubcategories.The conclusion is that both the subcontractor and Arcona see bothpractical and financial gains in introducing CSL in Uppsala. The mainadvantage of CSL is that it is scalable and you can choose to insertonly the sub-functions that are needed on the current project. Aservice that both sees benefits and which can be recommended is alogistics coordinator who reviews the entire logistics at theworkplace and thereby more easily identifies and solves problems.

    Framtida konsumtion på befintliga och nya handelsplatser: En plats- och konsumentundersökning för obemannade självservicebutiker2017Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Our demands on services and availability increases at the same time as the society gets more urbanized and more people tends to commute. In order to facilitate the consumer, technology based self-service (TBSS) stores might survive and thrive. This thesis had a focus on finding out the general public's perception on TBSS stores and how they perceive the availability even if it is unmanned. The extended marketing mix contains people as a means of competition and we wanted to investigate whether this competitive mean could be ruled out which would mean that the extended marketing mix needs to be revised.

    In order to find out the people's perception of the TBSS concept a short enquiry were constructed containing three questions. People from Uppsala central station and four countryside towns, corresponding to two percent of the population, answered this enquiry. In order to collect data for information concerning establishment a factor rating method with five chosen factors were performed.

    From the results of the enquiry we found that the majority of the respondents have a positive attitude towards TBSS, which means that the competitive mean people are not critical when it comes to consumer perception of accessibility; conclusion from this is that the extended marketing mix needs to be revised. The products that was stated most frequently were edible goods followed by ticket and fuel services. The analysis using the factor rating method exemplifies a way for companies to compare differents places for establishment from various chosen factors.

    Chemical signatures of the first stars2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The first stars are something many scientists are curious about. How did they formand how did the universe look like at that time? These stars however probably died along time ago, or are at a distance too far away from us to be observable. If these starsexploded and formed supernovae there might be stars observable today that formed fromthe ejecta of these supernovae. Models of nucleosynthesis in the first stars may potentiallybe used to infer parameters of progenitor supernovae from chemical abundances in old,metal-poor stars. This thesis aim is to find out how precise these abundances need to beto achieve a certain precision in the supernova parameters. This is done by perturbingthe abundances for one element at a time in four different stars and see how the recoveredsupernova parameters change. The first conclusion is that it isn’t necessarily the sameelements that are important for determining the supernova parameters in all stars, andif there is one thing that decides which elements are important it would be the star’smetallicity. The stars HE1327-2326 and HE0107-5240 metallicites are close to each other,with [Fe/H] < -5.0 and [Fe/H] = -5.3 respectively, and behaved similarly, the elementmost important in both stars was nitrogen. The star SMSS0313-6708, [Fe/H] < -7.3, hadmore elements that changed the parameters, the most important beeing C, O and Ca.The star CS 31028-001, [Fe/H] = -2.9, also had many elements that were important, andsome of them are Na, K and Ni.

    Implementering av innovationsprojekt i externt reglerade organisationer: en fallstudie av sambanden mellan påverkande faktorer2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studiens syfte är att (1) kartlägga de faktorer som påverkar implementering av innovationsprojekt i externt reglerade organisationer, (2) att utveckla en förklaringsmodell som beskriver sambanden mellan dessa faktorer. Undersökningen består av en fallstudie där ett läkemedelsföretag följs under uppstartsfasen av ett innovationsprojekt. Metoden som användes var induktivt kvalitativ. Data samlades in via semistrukturerade intervjuer, öppna observationer och dokument som var kopplade till innovationsprojektet. Studien visar att följande faktorer: interna relationer, resurser, extern reglering, ledningens inställning, intern styrning och intern kommunikation påverkar implementering av innovationsprojekt och att dessa faktorer både kan ha en positiv och en negativ inverkan på implementeringen. Vid utvecklingen av förklaringsmodellen fann studien att interna relationer och resurser är faktorer som har en direkt påverkan på implementering av innovationsprojekt och att extern reglering, ledningens inställning, intern styrning och intern kommunikation är faktorer som har en indirekt påverkan.

    Utbytesoptimering inom läkemedelsproduktion: Identifiering av kassationsorsaker inom AstraZenecas packningsprocess i Gärtuna2017Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The project aimed to deliver recommendations of how to optimize the yield of thepackaging process of tablets and capsules within AstraZeneca's facility in Gärtuna(Södertälje), Sweden. The project scope included nine packaging lines of blisterproducts with highly similar process steps. The crucial part of the puzzle was toidentify cassation sources within these production lines, which was achieved by thecombined methology of qualitative interviews, quantitative surveys and statisticalprocess control applied to logged production data.The following cassation sources were identified:- Cassation as a side effect of start-up controls within an order- Safety cassation of tablets when the blister machine stops- In many cases, the safety cassation also occours when the cartoner stops- A cut-in-half tablet causing cassation of multiple tablets in the rejection steps- Leftover product on the packaging line when the order is finished- Target conflict between high productivity of the production line and high yield withinthe order- Difficulty optimizing machines settings for small order sizes, leading to higher stopfrequency and therefore more safety cassation of tablets, as well as a higher risk thattablets are sorted out in control stepsWhich led to these recommendations:- Optimizing the yield as a target value for process optimization- Log the yield for all the process steps within the packaging line- Consider the possibility of reintroducing rejected blisters containing approvedtablets- Clear prioritization of the target conflict between high productivity and high yield- Analyze if there are any time-consuming steps conflicting with high yield within theprocess of closing an order which are not required to be performed at that particularprocess stepAs well as future work:- Get to the bottom of the correlation between low yield and small order sizes- Investigate further which materials are prone to cause machine stops within thecartoner- Dig deeper into the problem of cut-in-half tablets existing pre-packaging-process

    Abstract [en]

    The black hole information paradox arises when quantum mechanical effects are considered in the vicinity of the event horizon of a black hole. In this report we describe the fundamental properties of quantum mechanical systems and black holes that lead to the information paradox, with focus on quantum entanglement. While first presented in 1976, the information paradox is as of yet an unsolved problem. Two of the proposed solutions, black hole complementarity and firewalls, are discussed.

    (E)-α-bisabolene production in Synechocystis sp. PCC 68032017Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The world is currently facing many environmental challenges related to fossil fuels and meanwhile the global energy demand is increasing rapidly. The terpenoid (E)-α-bisabolene is a precursor of the potential diesel fuel replacement bisabolane, and has been proven possible to produce in the cyanobacterial strain Synechocystis sp. PCC 6803. The aim of this project was to increase the bisabolene production in said strain, as well as introducing the same engineered system into Synechococcus elongatus PCC 7942 for comparison. For this purpose, several constructs were constructed which all contained the first enzyme of the terpenoid biosynthesis pathway; 1-Deoxy-D-xylulose 5-phosphate synthase (DXS). These constructs were then conjugated into the cyanobacterial strains after which the bisabolene production of positive colonies was evaluated. One of the constructs proved to increase the production of bisabolene in Synechocystis sp. PCC 6803, however the introduced DXS gene could not be detected neither on a genetic nor a translational level. Furthermore, the conjugation of Synechococcus elongatus PCC 7942 proved unsuccessful and did not give any colonies.

    Identification of elements and molecules in the spectra of an M dwarf star using high resolution infrared spectroscopy.2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    M dwarfs are abundant and long-lived stellar objects. The formation of planets around stars in stellar systems is believed to be metallicity dependent. To determine the metallicity with synthetic spectrum analysis, the elements producing the absorption lines ofthe spectra first have to be identified. The aim of this thesis is to identify and list the elements or molecules that produce the absorption lines in the spectra of Barnard's star. This thesis was done at the Division for Astronomy and Space Physics at Uppsala University. High resolution infrared spectral data recorded in the J band 1.1–1.4 μm was downloaded from the CRIRES-POP database. The data had to be wavelength corrected due to the effects of Doppler shift. A modified IDL program was used to read the data files,normalize the flux to unity and plot the spectra. This procedure was also done with the telluric spectra using data from a solar flux atlas. The IDL program plotted the normalized spectra together in the same plot. With this procedure the absorption features originating from the earth’s atmosphere could be identified and discarded. The analysis of the spectral lines resulted in wavelength values which were tested against the VALD3 database to determine what elements were possibly responsible for the absorption features. The results are presented in a line list. It can be used with other software programs to determine the metallicity. The identified elements and molecules agrees in part with earlier measurements of stellar spectra from M dwarf stars except for a number of lines where no matching elements were found in the VALD3 database. A line list with possible elements in the photosphere of Barnard’s star can be constructed from the spectra using high-resolution infrared spectroscopy.
