Electric vehicles are becoming more common as one of many solutions to the increasingly serious problem of global warming. This comes with new safety challenges as batteries can upon malfunction or abuse enter thermal runaway and as a result catch fire or explode. The gases released from thermal runaway has been determined experimentally in published studies and have been shown to contain fluorina
Membrane proteins are important building blocks for several biochemical processes. The difficulty with membrane proteins is that they tend to be lowly expressed and can be difficult to manage. Therefore, membrane proteins are studied to a lesser extent than soluble proteins. Since membrane proteins are intrinsically hydrophobic, their purification and structural determination critically rely on so
MicroProteins are small, separately expressed parts of a larger protein and able to interfere with the full-length protein’s function. To enable modulation of hormone perception, microProteins were designed from the ethylene, cytokinin and gibberellin receptors. The protein isoforms designed to function as microProteins were overexpressed in Arabidopsis. Overexpression of a shortened gibberellin r
Järnvägsnätet i Sverige är över 15000 km långt. Järnvägsnätverket har en viktig roll i transporten av personer och gods i landet. Det är viktigt att övervaka och underhålla detta stora nätverk för att säkerställa god funktion och säkerhet. De senaste årtionden har utvecklingen av interferometriska syntetiska aperturradar (InSAR) och tidsserie tekniker lett till att forskare, geotekniker och ingenjThere is over 15,000 km of track in the Swedish railroad network. This network is vital for the transport of people and goods across the country. It is important that this network is monitored and maintained to ensure good function and safety. In recent decades the development of Interferometric Synthetic Aperture Radar (InSAR) and Time Series techniques has allowed researchers, geotechnicians and
A Jacobian free multigrid preconditioner for linear problems arising from Implicit Discontinuous Galerkin (DG) discretizations is implemented. The preconditioner is based on a multigrid method for a low order Finite volume (FV) discretization on a subcellgrid. L2-projections are introduced as a strategy to translate between the discretizations. Numerical tests on advection dominated linear advecti
Denna studie utgår från hypotesen att det finns mer läromedel av kvalitet som utgår från Lgr11, samt vilar på vetenskaplig grund och beprövad erfarenhet i svenskämnet än i musikämnet. Detta bekräftas under studiens gång. Bristen av läromedel gör att lärare ägnar mycket tid åt att skapa sitt eget material i musikämnet. Denna studie undersöker lärares tankar kring hur tillgången till läromedel i sveThis study starts with the hypothesis that there are more teaching aids that are designed in accord with Sweden’s latest curriculum Lgr11, based on science and proven experience in the subject Swedish than in music. This confirms later in the study. The lack of teaching aids means that teachers spend a lot of time on making teaching aids for the subject music. This study examines teachers’ thought
Modern emergency management is a demanding profession characterized by accelerated decision- making, dynamic information needs, and complex collaboration to execute mission objectives. Decision support systems in this setting must be suitably optimized in turn, with clear requirements to inform such design. To date, comprehensive approaches to capture these requirements remain underdeveloped, per
Rangitoto är en vulkanö som ligger nordost om Auckland, Nya Zeeland, och tillhör Aucklands vulkaniska fält (AVF) som består av ca 50 utdöda monogenetiska vulkaner. Eftersom Rangitoto har egenskaper som skiljer sig från de andra vulkanerna i området tror man att området genomgått en förändring och gått in i en ny fas. Det var ca 500 år sedan Rangitoto senast hade utbrott och eftersom storstadsområdRangitoto is a volcanic island, located northeast of Auckland, New Zealand, and belongs to Auckland Volcanic field (AVF), which consists of c. 50 extinct monogenetic volcanoes. Since Rangitoto has characteristics that makes it different from the other volcanoes in the area, it is believed that the volcanic field has undergone a change and entered a new phase. Rangitoto had its latest eruption abou
Momentum or trend following investing refers to trading strategies constructed around the idea that in financial markets, the current trend will, more often then not, prevail. In the context of asset prices, this means that previous returns or the price development of an asset is indicative of similar future returns and price development. While at odds with established theory such as the weaker fo
We develop methods for estimation, inference and optimization of causal effects from observational data with continuous treatments. We present a counterfactual prediction method based on the potential outcomes framework that estimates the expected value of a potential outcome given a treatment level and confounders. We show that the method identifies the average generalized treatment effect (AGTE)
Recording of medical procedures makes it possible for medical staff to review their work, learn from the mistakes and produce material for education. Medical videos tend to be long, which has an impact on usability and raises issues concerning memory storage. The aim of this master thesis is to make the material more user-friendly with an intelligent toolbox based on machine learning and image an
I den vetenskapliga artikeln ”The Lady Doth Proteset too Much: Kosovo and the turn of Ethics in international law”, presenterar Martti Koskenniemi en teori, gällande hur den internationella juristen använder moral som ett argument för att legitimera humanitära interventioner. Faran i detta blir enligt Koskenniemi att stater som redan besitter makt och militära resurser kommer använda lagen som ett
Several governments recently adopted strategies to facilitate the development of artificial intelligence (AI), one of the reasons being the pursuit of sustainability – a claim with little scientific grounding so far. In this thesis, I strived to outline the scope of AI’s potentials by showing i) the limits of its theoretical and practical usefulness and ii) the political barriers to using it for s
Fler företag ser värdet av att implementera ett CRM-system för att få konkurrensfördelar. Implementationen har visat sig vara en svår process och en majoritet anses misslyckas. Genom att identifiera kritiska framgångsfaktorer har akademin försökt underlätta för framtida implementationer genom att peka på faktorer som bör beaktas för en lyckad implementation. En stor del av denna litteratur lägger
This master thesis in library and information science is centered around two reading circles taking place at the libraries of Swedish upper secondary schools. The aim of the thesis is to study how the participants (ages 16-18) in the reading circles reflect on their own reading practices and their identities as readers. One main point of the thesis is that reading circles are forms of reading comm
The main purpose of this master's thesis is to explore how public libraries in Sweden work to increase digital skills among older people. This is done by studying social practices in digital technology workshops at local meeting places for older people. Public librarians participated as instructors and the purpose of these workshops was to enhance the digital skills of older people. This stu
