    Concept for battery change: Mining vehicles2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Epiroc Rock Drills AB in Örebro manufactures and develops machinery for the infrastructure required to maintain a fully operational mining industry, such as ventilation, drilling rigs, trucks and loaders etc.

    In these environmentally conscious times, a large market focus forzero emission machines has begun to emerge. By replacing today'sinternal combustion engines, mining companies can save large sums of money in ventilation costs and fuel while creating a more pleasant working environment in the mines. Due to these rapidly changing needs, Epiroc's machines must also change in design and performance. Epiroc has thus chosen to use interchangeable batteries in their new generation of mining machines. When the battery is discharged, it must be easy to replace with a fullycharged one. From an economic point of view, it is also important that the machine is always in production without any stops, making fast and efficient battery switches desirable. At present, the battery change is usually done with a mono-rail crane down the mine. This has proved to be very difficult and ineffective as the battery is too often jammed into the machine due to the fact that the machine is poorly positioned against the crane. Ceiling heightis also a problem, preferably one should have about 6-7 meters to accomplish a safe lift with the crane, which is not always possible down in a mine.

    In order to find a more long-term solution to this problem, this degree project took its start. During the course of the process, a number of methods in product development and concept generation have been used to develop different concepts and screen them based on the needs identified at the beginning of the work. The main problem was divided into four sub problems to facilitate conceptgeneration, the most promising sub concepts were visualized using CAD and then put together in different combinations. These combinations were then evaluated against today's solution to easily see what concept should be further developed.

    This resulted in a concept that consists of a separate platform,which can either be placed on a vehicle or as a stand-alone station. On this platform there are two telescopic arms, one on each side. These arms lifts the three ton heavy battery from the mining machine in an arcuate motion over a charged battery on the platform, placing it in a designated location and then lifts the charged battery into the machine. With this concept, it is also possible to accomplish a safe change with a limited ceiling height of approximately 3.5-4 meters, which is an improvement compared to today's solution.

    Automated IV-measurements for solar panels in stratospheric conditions2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this project an automated IV-measurement circuit able towithstand stratospheric conditions was developed. It was made to bepart of an experiment which will be executed at an altitude ofapproximately 27 km. The IV-measurements aim to conclude the powergenerated by the solar panels during the flight. The circuit is ableto adapt to different solar panels by use of a feedback circuit thatis able to adjust the voltage through varying resistor ratios.Different solar panels have been tested with the circuit in sunlightand the results show that it is successful in performing the intendedmeasurements. The circuit has also been tested in -80°C as well as0.01 kPa with no reduced functionability, which means it is wellfitted for stratospheric conditions.Tryckt av:

    Lojalitet på Instagram: Vilka faktorer påverkar lojaliteten hos ett företags instagramföljare?2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Today’s competition among companies has increased due to the development of the Internet. Customer loyalty is crucial for companies in today’s market. It is important to create a customer base, which will result in a positive effect on profit and sustainability. Social media, such as Instagram, has an impact on customers today. Social media has made it possible for companies to be closer to their customer than ever before. The purpose of this study was to explain how a company can influence Instagram followers’ loyalty through the use of Instagram. This study examines several crucial factors which are considered to have an impact on customer loyalty. The study uses a deductive approach and the data was collected using an internetbased survey posted on a specific Instagram account. The result of the empirical study shows evidence to support that the variables community, choice and word of mouth have a significant impact on loyalty through Instagram. There is no evidence in the study that the variables customization, convenience and character have any impact on customer loyalty. The study further examines and suggests that there is no significant relationship between an individual attitude towards a company and the individual actions on Instagram.

    Uppsala Parkering2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Heavy traffic in cities is an increasing problem that causes congestion. An inadequate infrastructure unable to scale to satisfy the growing amount of traffic is the main cause. Traffic congestion results in ineffective overhead traffic patterns. The overhead time spent in traffic is consuming valuable time from drivers and it also contributes to a heavier impact on the environment. A relevant portion of the traffic in cities, is search traffic: traffic with the sole intent of finding an available parking spot. Reducing the search traffic in cities would effectively hamper congestion. In a collaboration with Uppsala Parkering AB, a project was commenced with the aim of developing a solution that could contribute to reduce the search traffic in Uppsala. This aim was accomplished by the creation of a mobile application. The applications main feature is an interactive map that visualizes parking areas within a confined test area in Uppsala. The application is scalable and can be extended to cover a larger area. With the application, a user can find the closest suitable parking spot depending on custom preferences. The project did not have access to actual traffic data with real-time information of currently parked vehicles in Uppsala. To mimic the real-time data, a simulation was created and used in the application. The simulated data was used to demonstrate the varying availability of free parking spots in the different parking areas. By scaling up the application with additional parking areas and replacing the simulated data with actual traffic data, the application can be used as an aid to find suitable parking spots. Then the search traffic in Uppsala could potentially be decreased.

    Global satellite data as proxies for urbanization in flood prone areas2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Delta regions are typically characterized by their high population density, low elevation, and risk of flooding. Long term planning and preparation is needed to mitigate the adverse effects of floods. Disaster management planning and flood protection measures require information about urbanization patterns, but this information is lacking in many parts of the world. Global satellite data could potentially aid or replace local urbanization data in such data scarce areas. This master thesis assesses the suitability of two global satellite datasets to serve as proxies for urbanization in flood prone areas: the Global Human Settlement (data for 1975, 1990, 2000 and 2014) and stable Nighttime Lights data series (annual data, 1992-2013). The assessment is performed through comparison of spatial-temporal urbanization trends of the global datasets with a previous study performed in the Netherlands using detailed local data. These spatial-temporal trends involve the share or urban area that is situated in flood prone zones and the average inundation depth. Through analysis based on Geographic Information Systems it was found that the Global Human Settlement data series indicates a stable increase in the percentage of urban area in flood prone zones from 31.60% in 1975 to 36.54% in 2014. Potentially, this increase results from the flood protection measures installed between 1954 and 1997. The Nighttime Lights data series shows values of around 36% throughout its time period, with no clear increase or decrease. These values are on average 15-17% higher over the whole time series than the values found with the use of the local data. The Global Human Settlements dataset shows values for the average inundation depth from 1.47m in 1975 to 1.72m in 2014, similar to the local data. The increase could be explained by the fact that only areas with higher inundation depths are available for urbanization. The Nighttime Lights does not show a clear trend with values ranging from 1.52m to 1.70m and large annual variation. Overall, the suitability of the Global Human Settlement dataset is higher than the stable Nighttime Lights dataset for this study area as it shows values more similar to the local data and does not require prerequisite threshold analysis, which is the case for the Nighttime Lights data.

    Sustainable Urban Mobility: Transportation Solutions for Future Urban Environments2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This is a study of urban mobility, where urban areas are defined as diverse and complex locations with a metabolism composed of multiple components and subsystems. Currently, more than 60% of the world’s population live in urban areas, a number expected to grow significantly. Most cities are unsustainable and often in ecological deficit; cities over- consume or pollute their natural resources, while unequal distribution of resources also occur. Thus, leading to serious economic and social imbalances, something that is possible to appreciate in developing nation-states. With population growth and economic concentration in urban areas, transport policies are forcing governments to seek innovative solutions for shaping and re-shaping existing and future transportation systems. Transport infrastructure related to congestion, accidents, local air pollution and greenhouse gas emissions (GHG) is a challenge for many major cities in the world. This study covers the political and socio-economical processes with regards to the environmental challenges in the Peruvian transport system. It includes an analysis of the strategies and indicators of good governance by the central, metropolitan and local governments, with the aim of identifying the main drivers and barriers to improving the current transport system in Lima. It is important to highlight that urban mobility is an important component of urban planning and is constituted by the urban transport system, land use, traffic management, inter-modality, accessibility and public space management, among other things. The appropriate approach to urban mobility joins the vision of a city with citizenship (Ministerio de Vivienda 2016). From an Urban Political Ecology (UPE) perspective, one can appreciate that the transport system in Lima seems directly derived from complex social, economic and political relations and where environmental challenges are less vocal (Robbins 2012). And seen from the Entrepreneurial or innovative state and as described by Schumpeter, the role that a state or governments hold is crucial in a well-functioning society in the context of a capitalism society. An efficient government is vital in providing goods and services, rules and institutions for ensuring that the market grows, as well as directing citizens to a more prosperous life. Without such a government, sustainable development in social and economical aspects is impossible. However, the results of this study not only presents several challenges to the structure of the national, regional and local governments in Lima, but also the various dimensions to these challenges that exist. These insights are important to highlight and address, as moving towards an urban transformation that is sustainable and durable will require considerable intervention from governments to achieve substantial reductions in GHG emissions.

    En älv till låns: De strategiska samverkansprocesserna mellan ICEHOTEL och dess intressenter sett ur ett miljöperspektiv2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Hållbar utveckling är en grundpelare inom ICEHOTEL:s verksamhet och ett uppmärksammat begrepp i samhället. För att kunna driva sin verksamhet behöver ICEHOTEL samverka med sina intressenter. Tidigare forskning uppmärksammar dessa samverkansprocesser och talar även om hur ICEHOTEL:s arbete med hållbar utveckling skapar intresse bland aktörer såsom leverantörer och gäster. Med detta i åtanke är studiens syfte att kartlägga nätverket som ICEHOTEL verkar inom och studera hur samverkansprocesser mellan hotellet och dess intressenter påverkar ICEHOTEL:s förmåga att upprätthålla en hållbar verksamhet. Studien har baserats på material från intervjuer samt en observationsstudie som gjordes på ICEHOTEL i Jukkasjärvi. Intressenterna identifierades till “government”, “customers”, “employees”, “media”, “competitors” och “suppliers”. Undersökningen resulterade också i en förståelse att ICEHOTEL vidtar många åtgärder för att minska sin klimatpåverkan och att alla intressenter påverkar detta arbete på olika sätt genom att både möjliggöra och begränsa hotellets arbete. Vidare har alla intressenter både en ekonomisk och miljömässig påverkan på ICEHOTEL och studien visar att det finns ett samspel mellan dessa två typer av inverkan. Avslutningsvis menar denna studie att ytterligare begrepp för att förklara syftet med samverkansprocesser är nödvändigt då samverkan är ett icke-neutralt begrepp med skiftande betydelse.

    Attitudes to dental care, Sweden 2003-2013, and clinical correlates of oral health-related quality of life in 20132018In: International Journal of Dental Hygiene, ISSN 1601-5029, E-ISSN 1601-5037, Vol. 16, no 2, p. 257-266Article in journal (Refereed)
    Abstract [en]

    Objective: To investigate attitudes to dental care, and to assess possible associations with socio‐economic and clinical variables over a period of ten years, and to investigate the association between OHRQoL assessed by oral impact on daily performance (OIDP), and socio‐economic, dental care habits, smoking and oral status.

    Materials and methods: Cross‐sectional studies performed in the county of Dalarna, Sweden, in 2003, 2008 and 2013. Random samples of 1,107‐1,115 dentate individuals, aged 30‐85 years, who answered a questionnaire and who were radiographically and clinically examined were included.

    Results: The importance of preventive treatment, regular recalls and meeting the same caregiver as on previous visits became less important. In individuals with alveolar bone loss, meeting the same caregiver as on previous visits was important (P<.05). In individuals with manifest caries, information on treatment cost was important, while prevention became less important (P<.05). OIDP was reported by 31% of the individuals in the study, and frequent impact was reported by 10%. Individuals with manifest caries lesions, less than 20 remaining teeth, and temporomandibular disorders (TMD) reported OIDP to a significantly higher degree, compared to orally healthy individuals.

    Conclusion: Attitudes important in maintaining and improving good oral health, such as preventive care and regular recalls to dentistry, became less important during this period of 10 years. Oral impact was found to be associated with irregular dental visits and limited economy for dental care, individuals with less than 20 remaining teeth, TMD and manifest caries.

    Moving beyond the age-depth model paradigm in deep-sea palaeoclimate archives: dual radiocarbon and stable isotope analysis on single foraminifera2018In: Climate of the Past, ISSN 1814-9324, E-ISSN 1814-9332, Vol. 14, no 4, p. 515-526Article in journal (Refereed)
    Abstract [en]

    Late-glacial palaeoclimate reconstructions from deep-sea sediment archives provide valuable insight into past rapid changes in ocean chemistry. Unfortunately, only a small proportion of the ocean floor with sufficiently high sediment accumulation rate (SAR) is suitable for such reconstructions using the long-standing age-depth model approach. We employ ultra-small radiocarbon (C-14) dating on single microscopic foraminifera to demonstrate that the long-standing age-depth model method conceals large age uncertainties caused by post-depositional sediment mixing, meaning that existing studies may underestimate total geochronological error. We find that the age-depth distribution of our C-14-dated single foraminifera is in good agreement with existing bioturbation models only after one takes the possibility of Zoophycos burrowing into account. To overcome the problems associated with the age-depth paradigm, we use the first ever dual C-14 and stable isotope (delta O-18 and delta C-13) analysis on single microscopic foraminifera to produce a palaeoclimate time series independent of the age-depth paradigm. This new state of the art essentially decouples single foraminifera from the age-depth paradigm to provide multiple floating, temporal snapshots of ocean chemistry, thus allowing for the successful extraction of temporally accurate palaeoclimate data from low-SAR deep-sea archives. This new method can address large geographical gaps in late-glacial benthic palaeoceanographic reconstructions by opening up vast areas of previously disregarded, low-SAR deep-sea archives to research, which will lead to an improved understanding of the global interaction between oceans and climate.

    (O) Hållbar undervisning?: En studie om begreppet hållbar utveckling inom ämnena geografi och naturkunskap på gymnasieskolan2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Hållbar utveckling har på senare år fått en allt större roll i skolan. Främst har detta skett genom konceptet UHU -utbildning för hållbar utveckling, som ska prägla innehållet i utbildningen, men även sedan tre år tillbaka genom FN:s Agenda 2030. I Agenda 2030 lyfts FN:s globala mål fram, varav ett riktar sig till utbildning - att denna ska främja hållbar utveckling och möjliggöra hållbara livsstilar. Uppsatsen ämnar därför undersöka skillnader och likheter mellan två ämnen i gymnasieskolan, geografi och naturkunskap, när det kommer till vilka kunskaper de förmedlar angående hållbar utveckling. Detta för att se om de elever som inte läser geografi, eventuellt går miste om kunskap gällande hållbar utveckling. Undersökningen utfördes med hjälp av ämnesplaner och läroböcker, metoden som tillämpades var kvalitativ textanalys. Ännu en aspekt som togs in var huruvida läroböckerna gav möjlighet till utbildning om och för hållbar utveckling. Om syftar till att lära eleven om hållbar utveckling, medan för syftar till att påverka elevens livsstil. Analysen visade att geografi berör fler aspekter av hållbar utveckling, men främst håller sig till utbildning om hållbar utveckling. I naturkunskapen berörs istället färre aspekter, dessa gav dock i högre grad möjlighet till utbildning för hållbar utveckling.

    Bangladeshi women breaking societal norms: A field study of women who are attending engineering and science educations at Bangladesh University of Engineering and Technology2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Women and men are equal by law in Bangladesh, but the societal reality shows a different picture. By illuminating the obstacles women face when entering and choosing an engineering and science program and what enables women to overcome obstacles, this thesis aims to answer why there are fewer women than men at Bangladesh University of Engineering and Technology (BUET).  

     

    This thesis was a field study conducted at BUET. Questionnaires was handed out to get a broader perspective of women’s experiences within science and engineering while the interviews aimed to get an in-depth perspective of women’s own experiences being in science and engineering. The empirical data has been analysed using the Social Cognitive Career Theory (SCCT), the domestic responsibilities model and previous research about social norms within science and engineering and female networks. The thesis concludes that there are two main explanatory factors why there are fewer women than men studying science and engineering at BUET. Those factors are the social construct that science and engineering programs are more appropriate for men and that families do not have a beneficial Socioeconomic Status (SES) to allow women to study. The main factor enabling women to study and pursue an engineering and science program is family support.

    A Dangerous or Necessary Style?: An examination of the relevance of style in philosophy2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    No form of philosophy is without literary style. This is not always appreciated and opponents of style within philosophy often seem to be unaware of the role of style. Arguments that style is bad, good, or that diversity of styles is good needs to be investigated so that the underlying presuppositions and the meaning of different literary styles becomes clear.

    This thesis examines three arguments for and against style within philosophy and the relevance of literary style for the philosophical method. I investigate what arguments and fundamental assumptions about language that underlies the judgments that literary style in philosophy is either 1.) bad, 2.) good or, 3.) both bad and good (a diversity position).

    An analysis of three different positions to the question of the relevance of style will be performed. The analysis focuses on the basic understandings of what language is and does and reveals the underlying presuppositions of the attitudes towards style in philosophy. Only then can the different positions and attitudes towards style be defended and examined in an interesting and relevant way. The debate about philosophical style often misses a significant point because many are unaware of the philosophical presuppositions behind the arguments, and the argumentation risks to be flawed in relation to this.

    Firstly, a presentation of three different attitudes towards the relevance of style to the philosophical method is outlined. The approaches are represented by a reading of philosophers who either describe the relevance of literary style as 1.) bad, or not important for the method, 2.) important/necessary for the method, or 3.) that diversity is good for philosophy. Secondly, I examine how these three approaches are affected by the underlying philosophy of language with a focus on theories of metaphor. Depending on how one believes that language is related to reality and ourselves, one will assess style as a more, or less, relevant and contributing aspect of the philosophical work and method. The analysis shows that metaphors and other literary stylistic tools might sometimes be necessary and mediate something that cannot be expressed in another way: language can never capture the full potential of reality.

    Beyond the Betrayal of Language: On the Role of Skepticism in Otherwise than Being2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In Otherwise than Being (1974), Levinas asked if and how philosophy could make justice of the concrete ethical meeting by philosophical practice, which is unconditionally conditioned by language. Language, understood as partly situated in being and ontology, is analysed as an appropriation of the other, who is other than being. Language could therefore according to Levinas never fully express the other – sometimes referred to as “otherism”. A condition, then, that needs to be fulfilled for philosophical practice to reach the goal of making justice for the other, and hence be meaningful in the Levinasian picture, is to transcend language through language. In the essay, I analyse through textual interpretation what appears to be a contradiction regarding Levinas’ answer to the possibility of transcendence through and by language in philosophy. On one hand, it appears as if philosophy could not overcome language through language, and that philosophical practice therefore is not meaningful. On the other hand, it appears as if sceptical discourse could overcome language through language. Scepticism might then be considered as the only meaningful practice and philosophy a game of deconstructive dialogue. Since skepticism is understood as a part of philosophy, this would imply that there is a contradiction. I argue that the contradiction could be understood as apparent when considering the criticism executed in Levinas’ analysis of language. I suggest that the contradiction is apparent because sceptical interchange is meaningful.

    3d expansions of 5d instanton partition functions2018In: Journal of High Energy Physics (JHEP), ISSN 1126-6708, E-ISSN 1029-8479, no 4, article id 092Article in journal (Refereed)
    Abstract [en]

    We propose a set of novel expansions of Nekrasov's instanton partition functions. Focusing on 5d supersymmetric pure Yang-Mills theory with unitary gauge group on C-q,t(2) 1 x S-1, we show that the instanton partition function admits expansions in terms of partition functions of unitary gauge theories living on the 3d subspaces C-q x S-1, Ct-1 x S-1 and their intersection along S-1. These new expansions are natural from the BPS/CFT viewpoint, as they can be matched with W-q,W-t correlators involving an arbitrary number of screening charges of two kinds. Our constructions generalize and interpolate existing results in the literature.

    Framtidens miljöhjältar: En undersökning av hur Skolverkets läroplan igenkänns i barns uttryck kring miljö- och hållbarhetsfrågor2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I denna C-uppsats presenteras en kvalitativ fallstudie där barns sätt att uttrycka sig i miljöfrågor undersöks. Studien behandlar även barnens relation till naturen. För detta ändamål har fem barn ur en förskolegrupp intervjuats. Intervjuer har även gjorts med förskolepersonal i syfte att ge inblick i förskolans arbete med miljö- och hållbarhetsfrågor. Skolverkets perspektiv på vad barn ska förstå inom miljöfrågor synliggörs genom analyser av målen i Skolverkets läroplan för förskolan. Resultatet visar att läroplanens mål delvis kan igenkännas i barnens sätt att uttrycka sig om miljö och natur. Genom studien åskådliggörs även utmaningar och möjligheter kopplade till implementeringen av läroplanens miljörelaterade mål. Tidsbrist och svårigheter i att tolka läroplanen identifieras som de främsta utmaningarna för förskolepersonalen. Ur ett ECESD-perspektiv finns dock goda möjligheter att uppnå läroplanens mål med till synes enkla medel. Vidare behandlar studien problematiken i att översätta barns uttryck till ett mått på deras förståelse.

    Mineral Constraints on the Source Lithologies at Fogo, Cape Verde.2018Independent thesis Advanced level (degree of Master (Two Years)), 30 credits / 45 HE creditsStudent thesis
    Abstract [en]

    Variations in major, minor, and trace elements compositions and ratios, as well as isotope ratios are all useful tools in studying the composition of the Earth’s mantle, and heterogeneities present therein. Since the mantle itself doesn’t easily lend itself to study, ocean island basalt (OIBs) are commonly used as a proxy due to compositional differences combined with the range of origination depth, a combination that allows them to represent the heterogeneity of the mantle, sampling everything from the core mantle boundary to the old or recent additions of recycled oceanic crust. Fogo, being one of the most active volcanoes in the world, continuously samples the interior of our planet, and as such is a prime location for studies of mantle geochemistry.

    This study aims to determine the origin of the mantle lithologies present at Fogo. The study is a continuation and extension of the studies conducted by Barker et al. (2014) and Magnusson (2016).

    This study utilises major, minor, and trace element geochemistry in clinopyroxene and olivine phenocrysts, as well as Ni-isotopes from whole rock samples. Using the relative values of Ni, Mn, and trace elements and their ratios in olivine and clinopyroxene phenocrysts we aim to further unravel the mechanics of the creation of ocean islands and provide additional constraints regarding the mechanics of the formation of heterogeneities in the Earth’s mantle. This study will focus on Ni* and Mn* in olivine phenocrysts, trace element composition and ratios of olivine phenocrysts and clinopyroxene phenocrysts, and Ni-isotope data. 

    This study found evidence for both pyroxenite, carbonatite, and carbonated eclogite source lithologies at Fogo. A correlation between La/Sm and δ60Ni was also found, indicating a control on the δ60Ni by source pyroxenite.

    This study suggests a carbonated eclogite origin for the lithologies present at Fogo, which would have hosted the majority of the olivine phenocrysts. The phenocrysts then resided within a separated carbonatite melt fraction that either contaminated or metasomatized a pyroxenite melt where the clinopyroxene phenocrysts nucleated. The melt then evolved to an alkali basalt melt through melt-rock reactions, principally via the dissolution of orthopyroxenes and concomitant precipitation of clinopyroxene and olivine (Zhang, Chen, Jackson & Hofmann 2017).

    Hållbar utveckling i gymnasieskolan: En diskursanalys av hållbar utveckling i gymnasiekursen geografi 12018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this essay is to examine how textbooks that are used in the upper secondary school course geography 1, construct the term sustainable development. Four textbooks, as well as the curriculum for the course have been analyzed from a Foucaultian perspective of a discourse analysis. In the study both texts and pictures have been analyzed to understand how textbooks create the concept of sustainable development. The results show that the curriculum defines sustainable development as a central part of the course, but also describes other things that relate to the term without necessarily defining it as sustainable development. The textbooks presented a few themes that is relatable to sustainable development. Firstly, it is clear that sustainable development is a good thing and that it is something the reader is to strive for. It does so by promoting a lifestyle that is in line with sustainable development. Secondly, the textbooks present the difference between rich and poor countries and gives the picture that if we, the rich, help the poor people, then we will reach a sustainable development. Lastly the textbooks present faith in technological advancement as the solution to reach sustainable development.

    Effektivisering av delprocessen utleveranser: Ett förbättringsarbete på Gotlandssnus AB2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Gotlandssnus AB is an industrial organization that produces tobacco product snus and the nicotine-free option Qvitt. The company has experienced rapid growth since 2004 and qualitywork has been affected. After completion of a preliminary study, the subprocess deliveries was considered to be in need of improvement. The employees felt that the process consisted of unnecessary and time-consuming moments. The purpose of the study was to develop an improvement proposal for test including an implementation plan for the subprocess deliveries. Questions used in the study was (1) How can the subprocess delivery be improved? (2) Are proposed actions lead to improvment? (3) Can values, practices and tools from offensive quality development be applied in the improvement work of the subprocess deliveries? The theoretical background shows that offensive quality development can be described as a combination of values, practices and tools that work together to actively prevent quality shortages and promote continuous improvement efforts, instead of controlling and repairing. The DMAIC approach has provided the basis for the improvement work, where focus group meetings, semistructured interviews and observations have been used to collect qualitative data. For the collection of quantitative data, order history has been obtained and a time study has been conducted to base decisions on facts. The collected data has been analyzed using quality tools. The result shows that (1) The perceived problem with the subprocess was ineffective moments where the moment of labeling proved to be most time consuming and was considered duplication. In the subprocess production there was already a labeling moment that was possible to change. The moment could therefore be moved from subprocess deliveries to subprocess production. (2) The improvement resulted in increased efficiency in the subprocess deliveries without affecting the efficiency in the subprocess production. (3) The practic method DMAIC has created a systematic workflow in the improvement work using values that have been guiding. Tools have created the conditions for defining problems, measurement, analysis and improvement.

    Minskad användning av verksamhetsel i sjukhusmiljöer: Mänskliga och tekniska faktorer på Sahlgrenska Universitetssjukhuset2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis aimed to find how to affect and reduce the tenant electricity use in Sahlgrenska University Hospital (SU) through behavioural and technical factors. It also aimed to, in detail, chart and categorize the equipment that constitutes the tenant electricity and how large their contribution is to the total electricity usage. The research was delimitated to two separate departments within SU. To meet the goal of the thesis, a literature study on relevant fields of behavioural change science was carried out together with qualitative interviews with hospital staff. In addition to this, electricity use in both office and medical equipment was measured. The resulting analysis showed that lighting is by far the category of equipment that uses most electricity, about 50 % of the examined departments total use. The second largest category was office equipment, such as computers and computer monitors, followed by medical equipment. The analysis concluded that through use of feedback, nudging and transformational leadership it should be possible to change the staffs behavioural pattern. Although, it is probably more efficient to use technical solutions such as automated lighting and energy saving modes on computers to reduce electricity use. In addition to the analysis, or as a result thereof, this thesis resulted in a list of recommendations for the hospital, both for implementing a behavioural change programme and technical solutions aimed at reducing electricity use.

    Beslutsstöd: Effektivisering av ett beslutsstöd för tågtrafikledning i Sverige2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Business Intelligence, BI, is a tool for collecting, analysing and transforming data into useful information, information which is supposed to help making decisions and controlling a business’s operations. Business Intelligence leads to increased efficiency and optimizing the decision making within the organisation or its functions. It is designed to support the operator so that decisions are made quickly and accurately. The purpose of this study is to deliver a specification of requirements of value-adding information in a decision support system used by traffic coordinators at SJ. In order to reach the purpose, the qualitative study was designed in three steps, identification, prioritization and information analysis. The project was defined only to take one specific process in consideration: error-searching caused by vehicle damage. The study was initiated with interviews, observations and workshops and ended with an analysis of XOD, the current base of information. The study resulted in a specification of requirements, containing 21 different types of important information. Out of the 21 types of information currently existing in XOD, only about 52 % was considered value adding for the specific process. Besides that, the traffic coordinators experienced missing information, which was added in the specification of requirements. The heavy amounts of information was shown to be too much to take in consideration at once, which led to the conclusion that the business intelligence needs to be automated in order to optimize the decision making process.

    Evaluation of code generation in agile software development of embedded systems2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Generating code from software models is considered to be a new generation leap within software development methods. The objective of this M.Sc. project is to evaluate how different approaches to modelling and code generation affect embedded systems software development and propose recommendations on how to improve software development. Two product areas at Saab Surveillance EW Systems in Järfälla, Stockholm, are used as study objects.

    A research overview is made to highlight themes regarding modelling, code generation and software development in general. Based on these, interviews are held with system engineers and software developers at each product area, where they use different modelling and code generation approaches. The two development processes are described thoroughly. Challenges and advantages related to each area’s approach are investigated.

    Software development within product area A is affected by the product complexity and the larger scale of the development, including projects running over a longer time with more teams involved. Recommendations include enabling code generation by aligning it with other investments on process improvement and limiting the approach to generating some system components. Software developers within product area B can use full code generation, enabled by the limited product complexity. The product area is affected by software standards and external requirements on the process. Recommendations include extending the modelling approach to make it easier to trace functionality from system to software level. Conclusions are that both product areas can apply modelling and code generation to more software development activities to improve their respective development processes.

    Finanskrisens påverkan på företagsförvärvens värdeskapande: En studie på den svenska marknaden2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Trots att finanskrisen 2008 tog sin början i USA till följd av en övervärderad och överbelånad bostadsmarknad, kritiserades många bolagsstyrelser världen över för krisens breda spridning och utveckling. På grund av kritiken skapades nya riktlinjer inom bolagsstyrningen, vilket också medförde klara förbättringar i bland annat företags riskhantering vid större investeringsbeslut. Krisen ledde även till att aktieägare blev mer medvetna och försiktiga i deras investeringar, vilket gjorde att allt större fokus i företagen lades på att skapa värde för dem.Tidigare studier pekar på att företag ofta genomför företagsförvärv som av marknaden upplevs som värdeförstörande, då det största värdet faller i händerna hos aktieägarna i det uppköpta företaget. De nya riktlinjerna och de klara förbättringarna i bolagsstyrningen ger indikationer på att företag efter finanskrisen istället genomför förvärv som skapar värde åt det förvärvande företaget och deras aktieägare. Denna studie jämför därför värdeskapandet av företagsförvärven i perioden före och efter finanskrisen genom en eventstudie. Resultatet indikerar på att företagsförvärv som är genomförda efter finanskrisen är mer värdeskapande än de som genomförts innan, både dagen för offentliggörandet men också på kort sikt efter.

    Trends in Forest Soil Acidity: A GAM Based Approach with Application on Swedish Forest Soil Inventory Data2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The acidification of soils has been a continuous process since at least the beginning of the 20th century. Therefore, an inquiry of how and when the soil pH levels have changed is relevant to gain better understanding of this process. The aim of this thesis is to study the average national soil pH level over time in Sweden and the local spatial differences within Sweden over time. With data from the Swedish National Forest Inventory, soil pH surfaces are estimated for each surveyed year together with the national average soil pH using a generalized additive modeling approach with one model for each pair of consecutive years. A decreasing trend in average national level soil pH was found together with some very weak evidence of year-to-year differences in the spatial structure of soil pH.

    Matrix factorization in recommender systems: How sensitive are matrix factorization models to sparsity?2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    One of the most popular methods in recommender systems are matrix factorization (MF) models. In this paper, the sensitivity of sparsity of these models are investigated using a simulation study. Using the MovieLens dataset as a base several dense matrices are created. These dense matrices are then made sparse in two different ways to simulate different kinds of data. The accuracy of MF is then measured on each of the simulated sparse matrices. This shows that the matrix factorization models are sensitive to the degree of information available. For high levels of sparsity the MF performs badly but as the information level increases the accuracy of the models improve, for both samples.

    Automatic Essay Scoring of Swedish Essays using Neural Networks2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    We propose a neural network-based system for automatically grading essays written in Swedish. Previous system either relies on laboriously crafted features extracted by human experts or are limited to essays written in English. By using different variations of Long Short-Term Memory (LSTM) networks, our system automatically learns the relation between Swedish high-school essays and their assigned score. Using all of the intermediate states from the LSTM network proved to be crucial in order to understand the essays. Furthermore, we evaluate different ways of representing words as dense vectors which ultimately have a substantial effect on the overall performance. We compare our results to the ones achieved by the first and previously only automatic essay scoring system designed for the Swedish language. Although no state-of-the-art performance is reached, indication of the potential from a neural based grading system is found.

    Classifying Hate Speech using Fine-tuned Language Models2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Given the explosion in the size of social media, the amount of hate speech is also growing. To efficiently combat this issue we need reliable and scalable machine learning models. Current solutions rely on crowdsourced datasets that are limited in size, or using training data from self-identified hateful communities, that lacks specificity. In this thesis we introduce a novel semi-supervised modelling strategy. It is first trained on the freely available data from the hateful communities and then fine-tuned to classify hateful tweets from crowdsourced annotated datasets. We show that our model reach state of the art performance with minimal hyper-parameter tuning.

    Characterization of Wind Channeling Around Longyearbyen, Svalbard2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Due to climate change and arctic amplification, the avalanche activity is expected to increase at higher latitudes (Hall et al., 1994). The arctic settlement of Longyearbyen, Svalbard, situated inside the valley Longyeardalen, is yearly threatened by avalanche activity (Eckerstorfer & Christiansen, 2011a). The surrounding slopes are known to produce avalanche, and during the last century they have proven to be able to cause substantial damages and even fatalities (Hallerstig, 2010). Previous studies investigated magnitude and forcing of the avalanches, including a meteorological perspective (Eckerstorfer & Christiansen, 2011b). This allowed for the usage of forecasts from the weather model AROME-Arctic in order to have an avalanche bulletin.The forecast for the area of Longyearbyen suffers from the location and the insufficient resolution of its source data. The data are obtained from an AWS located at the local airport, at the mouth of a relatively wide NW/SE oriented valley. Conversely, Longyeardalen is oriented NE/SW and is narrower. Because of the topography, channeling of winds is expected to produce difference weather conditions at the two sites, generating two distinct local weather conditions (Whiteman, 2000). If these different weather conditions are not taken into account, the weather model may provide forecasts that are not reliable for the area of Longyeardalen, hence resulting in biased avalanche bulletins.In this work I compare the data from the airport, from Longyeardalen and from the plateau above in order to assess if relevant differences exist in some important meteorological parameters (temperature, wind speed and direction, precipitation) between these sites. The weather station at the airport is an official AWS while the data from the other two sites were obtained using portable weather stations deployed during a field campaign between March 1st and April 11th 2018. During this time, snow data from the slopes surrounding Longyeardalen were also obtained. These data have been used to look for correlations among the wind conditions in the valley and the depth of the snow, as it is known that snow transport is a major factor determining snow accumulation in the area (Jaedicke and Sandvik, 2002; Hestnes, 2000).Temperature and precipitation have been found to be consistent among the two investigated valleys, while wind parameters differed significantly. Wind speed in Longyeardalen is on average overestimated by 3 m/s if only the data from the airport are used while the direction data are uncorrelated. This is due to the different circulations that occur at the two sites. Adventdalen is mostly influenced by southeasterly winds that are forcedly channeled or induced by the synoptic circulation, while in the smaller Longyeardalen southerly winds prevail due a thermal circulation induced by the presence of two glaciers on the top part of the valley. Snow depth is altered by the wind transport but it was not possible to find any correlation due to the low resolution of the snow depth data.

    A permutation evaluation of the robustness of a high-dimensional test2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The present thesis is a study of the robustness and performance of a test applicable in the high-dimensional context (𝑝>𝑛) whose components are unbiased statistics (U-statistics). This test (the U-test) has been shown to perform well under a variety of circumstances and can be adapted to any general linear hypothesis. However, the robustness of the test is largely unexplored. Here, a simulation study is performed, focusing particularly on violations of the assumptions the test is based on. For extended evaluation, the performance of the U-test is compared to its permutation counterpart. The simulations show that the U-test is robust, performing poorly only when the permutation test does so as well. It is also discussed that the U-test does not inevitably rest on the assumptions originally imposed on it.

    När moderskapet inte är tillräckligt: En komparativ studie av Birgitta Trotzigs Dykungens dotter och Sara Stridsbergs Happy Sally2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I beskrivningar av Sara Stridsbergs författarskap är Birgitta Trotzig ett återkommande namn. Främst har deras språkliga likheter betonats, men det finns även innehållsmässiga likheter då de båda återkommer till att skriva om moderskap. I denna uppsats jämförs hur moderskap gestaltas i Brigitta Trotzigs Dykungens dotter (1985) och Sara Stridsbergs Happy Sally (2004). Främst studeras hur moderskap gestaltas i de två romanerna, på vilka sätt moderskapet bryter från de rådande könsnormerna samt på vilka sätt verken problematiserar de moraliska aspekter och dilemman som kvinnlig frigörelse och moderskap innebär. Jämförelsen görs genom en tematisk komparativ läsning, och nyckelbegrepp i läsningen är genuskontrakt och norm. I båda romanerna ges en komplex bild av moderskapet, där både kvinnor som vill ha barn och kvinnor som väljer att göra abort skildras. I både Dykungens dotter och Happy Sally finns karaktärer som bryter mot den traditionella modersrollen och mot genuskontraktet, och för dessa normbrott krävs att de betalar ett pris. En skillnad i romanerna är huruvida karaktärerna bryter mot normen av fri vilja eller inte.

    Linear Mixed Models - Assessing the Relationship Between a Biomarker and Cancer Disease Status2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Previous research suggests that a specific biomarker measured in the blood correlates with cancer status, for a specific type of cancer: higher values of the biomarker are generally found in patients with progressive cancer. The aim of this study is to investigate this relationship using a Linear mixed model. Patients with a progressive disease have on average significantly higher values of the log of the biomarker and patients with partial or complete remission of the disease have on average significantly lower values of the logged biomarker, both compared to patients with a stable disease. Also, patients with a liver tumor have on average higher values of the log of the biomarker, compared to patients without. Including both a random intercept and a random slope in the Linear mixed model, in addition to the fixed effects, results in the best model fit. Due to the non-random sample used, these results are only valid for this specific sample but can be of guidance for the conduction and planning of future studies.

    Les durs et les pédés: Maskulinitetsnormer i Édouard Louis roman En finir avec Eddy Bellegueule2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning

     

    Syftet med denna uppsats har varit att studera maskulinitetsnormer i En finir avec Eddy Bellegueule, den franska författaren Édouard Louis debutroman, med utgångspunkt i R. W. Connells maskulina hierarkisystem och maskulinitetsforskning av bland andra Michael Kimmel och Sonya Rose. Romanen, som är självbiografisk, skildrar en homosexuell pojkes uppväxt i en liten by i den franska arbetarklassen. I min uppsats analyserar jag hur hans omgivning förhåller sig till de maskulinitetsnormer som råder i byn, samt vilka överträdelser från normerna som sker. Genom överträdelserna tydliggörs vilka normer som är rådande. Uppenbart blir att det maskulina hyllas och det feminina förtrycks. Romanen bekräftar i stort sett Connells hierarkiuppdelning, den är full av maskulinitetsnormer och män som hyllar det hegemoniska idealet. Resultatet av min analys visar att alla män i romanen är offer för maskulinitetsnormerna, oavsett var i hierarkin de befinner sig, eftersom normerna är destruktiva och begränsar deras livsmöjligheter.

    Speeding up PARAFAC: Approximation of tensor rank using the Tucker core2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In this paper, the approach of utilizing the core tensor from the Tucker decomposition, in place of theuncompressed tensor, for nding a valid tensor rank for the PARAFAC decomposition is considered.Validity of the proposed method is investigated in terms of error and time consumption. As thesolutions of the PARAFAC decomposition are unique, stability of the solutions through split-halfanalysis is investigated. Simulated and real data are considered. Although, no general validity ofthe method could be observed, the results for some datasets look promising with 10% compressionin all modes. It is also shown that increased compression does not necessarily imply less timeconsumption.

    Abstract [en]

    The aim of this paper is to investigate if rainfall prediction (nowcasting) can successively be made using a deep learning approach. The input to the networks are different spatiotemporal variables including forecasts from a NWP model. The results indicate that these networks has some predictive power and could be use in real application. Another interesting empirical finding relates to the usage of transfer learning from a domain which is not related instead of random initialization. Using pretrained parameters resulted in better convergence and overall performance than random initialization of the parameters.

    Matematikundervisning i första klass: Likheter och skillnader i hur lärare hanterat undervisning efter elevers olika nivåer i fyra tidsperioder mellan 1962–20112018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Carolina Wallerström: Matematikundervisning i första klass; Likheter och skillnader i hur lärare hanterat undervisning efter elevers olika nivåer i fyra tidsperioder mellan 1962–2011. Uppsala Universitet: Inst. för idé och lärdomshistoria, c-uppsats, vårterminen 2018.

    Syftet är att undersöka hur undervisningen i skolan har hanterat elevers olika nivåer inom matematiken under fyra olika tidsperioder mellan 1962 – 2011. Här studeras vad som generellt beskriver vad som karaktäriseras med respektive tidsperiod med hjälp av nyckelord. Nyckelorden baseras på vad i materialet, som primärt är lärarhandledningar, har ansetts tydligast att komma fram ur materialet gällande vad i undervisningen eller i undervisningens metoder som är centralt för att hantera elevers olika nivå i undervisningen. Undersökningen tar stöd genom, Anders Burman och Esbjörn Larsson, som givit ett brett historiskt perspektiv på skolan genom pedagogikens historia respektive skolsystemets historia. Daniel Lövheim har gett en mer specifik bild av debatten om den naturvetenskapliga debatten under 1900 talet och val av metod i denna undersökning bygger till stor del på hur han beskriver att han har valt sina teman. Från det stora och breda perspektiv som Burman och Larsson tillfört till den naturvetenskapliga debatten som tillförts genom Lundin finns det möjlighet att gå in mer specifikt på ämnet matematik genom filosofen Sverker Lundin och Anders Prytz, lektor i didaktik. De har båda undersökt matematiken i skolan varav Lundin har kritiserat ett flertal olika områden inom matematiken och Prytz fokuserat på styrningen av matematiken i skolan på olika sätt. Genom att jämföra hur lärare instruerats till att hantera olika elevers nivåer att lära sig matematikundervisningen i de olika perioderna, som är undersökningens syfte kan man se skillnader och likheter under perioderna. Den första perioderna handlar om att få möjlighet att räkna ett stort antal uppgifter efter nivå och de två senare perioderna om att få möjlighet att ta sin tid och under den fjärde perioden som undersökts betonas vikten av att varje elev känner sig självsäker och lust kring matematiken.

    Big Data Validation2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    With the explosion in usage of big data, stakes are high for companies to develop workflows that translate the data into business value. Those data transformations are continuously updated and refined in order to meet the evolving business needs, and it is imperative to ensure that a new version of a workflow still produces the correct output. This study focuses on the validation of big data in a real-world scenario, and implements a validation tool that compares two databases that hold the results produced by different versions of a workflow in order to detect and prevent potential unwanted alterations, with row-based and column-based statistics being used to validate the two versions. The tool was shown to provide accurate results in test scenarios, providing leverage to companies that need to validate the outputs of the workflows. In addition, by automating this process, the risk of human error is eliminated, and it has the added benefit of improved speed compared to the more labour-intensive manual alternative. All this allows for a more agile way of performing updates on the data transformation workflows by improving on the turnaround time of the validation process.

    Abstract [en]

    In this thesis I study how geneticist and racebiologist Gunnar Dahlberg, through his own writings and participation in the UNESCO statements on ”race”, came to define the concepts of ”race” and ”science”. Dahlberg was a stark opponent of the ”Nazi race doctrine”. He was also in a unique position as head of the State Institute for Human Genetics and Race Biology, during the period here examined. Questions have recently been raised as to how to understand scientists like Dahlberg when he, as well as many other antiracists of his time, did not deny the existence of visible and scientifically provable ”races”. One conlusion I draw is that Dahlberg, nevertheless, in many ways sought to replace the ”race” concepts in his time, for the biological concept of ”isolates”. I also state, in accordance with what other historians of scientific racism has shown, especially when dealing with the UNESCO statements, that the furthering of biological notions was upheld by other scientific areas, such as anthropology. The case was also vice versa, making ”race” at its core biological, but to its exterior a question of social environment. Relying on Thomas F. Gieryns theories of Boundary-work, I want to further our knowledge of how this was made possible. The aim is to show how Dahlberg, rethorically, drew boundaries for the ”scientific truth” about ”race”. I also intend to shed some light on how these contests for authority where percieved and related to by others. In this respect, one conclusion is that concepts of ”modernity”, and different uses of history where employed as demarcations. I will also show how, in dealing with the criticism of the statements, UNESCO produced a pluralist concept of science. Withall, this is a history that raises important questions about science, politics, and the work – consensuses and contests – that foregoes the categories later used to describe and, or, divide human beings.

    Varför var the New Deal fascism?: De amerikanska kommunisternas dragkamp om Roosevelts National Industrial Recovery Act2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna uppsats är att undersöka de amerikanska kommunisternas samtida diskussion kring och kritik av Roosevelts National Industrial Recovery Act , samt att analysera deras interna dragkamp om hur denna skulle tolkas och förstås i relation till fascism. Detta genomförs genom att studera kommunistiska tidningar från stalinister och trotskister. Tidigare forskning om ämnet har negligerat kommunisternas syn på lagen, alternativt avfärdat den som simpel dogma. Denna studie visar tvärtemot att både NIRA och fascism var föremål för en omfattande maktkamp mellan de kommunistiska lägren, och att kommunisternas förståelser och tolkningar byggde på komplexa teorier och utförliga analyser som anknöt till många olika koncept som bl.a. krig, terror, juridik, rättigheter, statens makt och begränsningar, symboler, statsvetenskaplig teori, och ideologier. Därmed kan studien också bidra till att problematisera och nyansera den rådande bilden av the New Deal, som i såväl forskning som populär mening har förståtts och förstås och används fortfarande som ett enhetligt, socialistiskt och progressivt fenomen.

    Towards a new generation of movie recommender systems: A mood based approach2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The emergence of the content overloaded internet creates a lot of new challengesfor users and service providers a like. To minimize the displayed amount of contentlike movies, music, or other products service providers like Netflix or Amazonare using recommender systems which aim to guide the user trough the availableinformation. These systems collect knowledge about the user and try to deliver personalized experiences. Most of the state-of-the-art recommender systems are using acontent focused approach but often fail to grasp the nature of users’ desires. Therefore,a mood-as-input model is developed which combines the existing research onhuman mood identification and the emotion classification of content in the domainof movies. In order to match these two components different machine learning modelsare evaluated and a Random Forest is selected as the main matching algorithm.The results of this study indicate that the mood of a user can be used to create personalizedcontent recommendations and that it can perform better than an Arbitrarysystem.

    Att skapa sig själv: Carl Peter Thunbergs persona konstruerad genom hans reseskildring2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis by the name To create oneself: Carl Peter Thunberg’s persona constructed by means of his travel account draws inspiration from recent studies within the history of science regarding the concept of persona. It seeks to expand the notion of persona to examine how it could be constructed and refined by individuals. In doing so, it offers an alternative approach to persona. Not as intellectual standard types but as a joining together of qualities that through the joining creates unique personae to each individual. Furthermore, the essay looks at change, and how it could function as an aspect of a persona. In order to examine this, I will look at how the persona of Carl Peter Thunberg was constructed in his travel account which was published in four parts and covered his travels in Europe, Africa and Asia in the 1770s. Thunberg was one of Carl von Linné’s students and a natural historian and physician in his own right. His travel account was widely anticipated and offered an opportunity for him to introduce himself to a wider audience. This source is exemplary for this kind of analysis as all four parts of the travel account existed within the same genre and was written for the same public, yet changes occurred in how Thunberg was portrayed. Rather than explaining these changes in how Thunberg was portrayed by changes in his personal circumstances, I will argue that they are best understood by considering the aspect of change as a central strategy in constructing Thunberg’s persona as a evolving scientist and natural historian.

    High-variance multivariate time series forecasting using machine learning2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    There are several tools and models found in machine learning that can be used to forecast a certain time series; however, it is not always clear which model is appropriate for selection, as different models are suited for different types of data, and domain-specific transformations and considerations are usually required. This research aims to examine the issue by modeling four types of machine- and deep learning algorithms - support vector machine, random forest, feed-forward neural network, and a LSTM neural network - on a high-variance, multivariate time series to forecast trend changes one time step in the future, accounting for lag.The models were trained on clinical trial data of patients in an alcohol addiction treatment plan provided by a Uppsala-based company. The results showed moderate performance differences, with a concern that the models were performing a random walk or naive forecast. Further analysis was able to prove that at least one model, the feed-forward neural network, was not undergoing this and was able to make meaningful forecasts one time step into the future. In addition, the research also examined the effec tof optimization processes by comparing a grid search, a random search, and a Bayesian optimization process. In all cases, the grid search found the lowest minima, though its slow runtimes were consistently beaten by Bayesian optimization, which contained only slightly lower performances than the grid search.

    Att materialisera (fram)tiden: Om temporalitet och modernitet i Magasin för konst, nyheter och moder2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this thesis is to examine and analyse if it is possible to distinguish a new perception of time and temporality in the Swedish fashion magazine Magasin för konst, nyheter och moder, and in that case how it is expressed. To discover this, I have used the theories of the philosophers and historians Reinhart Koselleck and Marshall Berman. In their works they have pointed out and described how the early decades of the nineteenth century was a crucial time for our perception of the modern world, in the sense that we ever since then have experienced a gap between the past and the future where we cannot derive our expectations from our past experiences anymore. I have studied if this notion is communicated in the articles, and came to the conclusion that there is a new awareness of time articulated in the magazine. Mainly  there are three different understandings of time and temporality expressed within the magazine – first are those articles that shows a general new awareness of time in a constructive way, neither through a positive or negative perspective. Furthermore, there are also expressions for connections between the materialistic content in the magazine and the view on temporality, where the acknowledgment of a new temporality in fashion seems to also have an impact on a more ideological perception of time. Finally there are articles which portrays the discrepancy between expectation and experience as something with a negative significance for the future, but similarly puts this in a way that illuminates that the future is now something adaptable and possible to influence in a certain direction. This shows a new way of understanding how, in a Swedish nineteenth century context, material culture could affect people’s awareness of time and temporality and hence also their thoughts and outlook of the future even in more abstract issues. The upcoming becomes possible to interpret as something materialistic, and therefore also something more concrete and arguable.

    A comprehensive summary and categorization of physical quantity libraries2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In scientific applications, physical quantities and units of measurement are used regularly. If the inherent incompatibility between these different units is not handled properly it can lead to major, and sometimes catastrophic, problems. Although the risk of a miscalculation is high and the cost equally so, almost no programming languages has support for physical quantities. Instead developers often rely on external libraries to help them spot these mistakes or prevent them all together.

    There are several hundred of these types of libraries, spread across multiple sites and with no simple way to get an overview. No one has summarized what has and has not been achieved so far in the area leading to many developers trying to ‘reinvent the wheel’ instead of building on what has already been done. This shows a clear need for this type of research.

    Employing a systematic approach to look through and analyze all available physical quantity libraries, the search results were condensed into 82 libraries which are presented in this thesis. These are the most comprehensive and well-developed, open-source libraries, chosen from approximately 3700 search results across seven repository hosting sites. In this group, 30 different programming languages are represented. The goal is for the results of this thesis to contribute to a shared foundation on which to build future libraries as well as provide an easy way of spreading knowledge about which libraries exist in the area, thus making it easier for more people to use them.

    Harnessing the power of the Internet of Things: A Performance-impact model for Companies´adoption of the Internet of Things.2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Every day, more and more devices are getting connected to the Internet and becoming what we know as the Internet of Things (IoT). In both commercial and industrial context, IoT plays a significant role in enabling automatisation and connectivity. For companies that want to become the innovation leader in their branch of industry, IoT is a useful method to gain competitive advantage where automatisation, predictive maintenance and connectivity can improve company’s performance. However, no research have been done from the perspective of an IoT-provider. How they can fully harness the power of IoT when they adopt it for their existing products or services? This study aim to investigate how a theoretical model would look like with the performance impact in focus when an innovation-driven company adopt IoT on their existing products. The research is conducted with a case study of a Swedish company in the heavy industry sector, which has successfully adapted IoT into their products. The empirical data was collected through documentation review and interview. This study results in a conceptual model that contains crucial factors which needs to be taken into consideration when adopting IoT. However, further research needs to be done, in order to verify this model as well as to be able to generalise the findings to cover innovation adoption in general.

    Förändring behövs i min samtid!: En undersökning av Johan Almkvists skrift Sexuallivet i våra samhällen och möjligheten av dess förbättrande.2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I denna uppsats ges en analys av läkaren Johan Almkvists skrift Sexuallivet i våra samhällen och möjligheten av dess förbättrande. Skriften publicerades 1942, under en tid av stora förändringar inom sexualpolitiken i Sverige. Då läkarna under denna tid fått en större vetenskaplig auktoritet även inom sexuallivet kan denna skrift ses som en representation för sin tid. Genom en analys av texten i jämförelse med samtidens samhälle påvisas en läkares tankar om förändringen gällande sexualiteten och varför en publikation av detta slag ansågs behövas. Uppsatsen undersöker vad denna läkare ansåg behövde förbättras i samhället och varför, samt hur detta skulle uppnås. Analysen är upplagd utefter de stora teman boken berör, rashygien, samhällsnytta samt könssjukdomar och sexualupplysning, teman som också var stora i samhället under denna tid. I uppsatsen framhålls hur Almkvist ansåg att sexuallivet skulle bli mindre samhällsskadligt genom att hålla sig till de skyldigheter han ställer upp. Skyldigheter som alla berör just områdena kring rashygien, samhällsnytta samt könssjukdomar och sexualupplysning.
