Mörk materia, som det ofta kallas, utgör den största delen av materian i Universum. Då den inte interagerar med synligt ljus, är det omöjligt att observera dess närvaro direkt. Istället får man tillta indirekta metoder, där man kollar på hur objekt som är synliga påverkas av den mörka materiens närvaro. Ett exempel på en sådan metod är att studera egenskaper hos så kallade stellar streams, eller `Satellite galaxies on bound orbits around the Milky Way (MW) are constantly subject to tidal forces from the MW. If the tidal forces are large enough, they may strip the outermost stars of the satellite, that in turn distribute themselves in long elongated stellar streams. These stellar streams are good probes of the Galactic potential due to the constraints they place on the structure of the pote

Menstrual hygiene management (MHM) is essential for those who menstruate because they have different needs during disasters and crises. Current MHM is focused on immediate needs instead of longer-term vulnerabilities and capacities. The purpose of this thesis is to examine how gendered vulnerabilities and capacities are considered in MHM policies and practice. The aim is to bring more focus to the

The main purpose of this thesis is to prove the Bieberbach inequality using Grönwall’s area theorem, and discuss some consequences of the Montel’s theorem and Carathéodroty convergence theorem regarding single-slit maps, which is essential to the proof of de Branges’ theorem.

The recent spread of COVID-19 pandemic encouraged organisations to facilitate a remote work environment for their employees. This work environment would most likely continue in the upcoming years. At the same time, this context has been followed with an increase in cyberthreats that could affect the optimal processes of organisations. Because of this, cybersecurity awareness must be cultivated to

Kan maskininlärning hjälpa oss förutspå njurskada i sepsispatienter? Årligen drabbas omkring 40000 människor i Sverige av sepsis och närmare 20% av dessa avlider som följd av sjukdomen. Trots detta är sepsis ett relativt okänt sjukdomstillstånd för allmänheten och även inom akademin är det ett relativt ostuderat område. Således finns det ett stort behov av en fördjupad förståelse av sepsis. SepsiSepsis-induced Acute Kidney Injury (AKI) is a common cause of death for sepsis patients, yet it is poorly understood by the medical community. Using Tandem Mass Spectrometry (MS/MS), the blood plasma of 135 sepsis patients has been analyzed to measure protein levels. In this thesis we will present an exploratory application of machine learning on this data, with the intent of producing a model wh

This study examines the relationship between environmental, social and governance performance and corporate credit risk, adding to the literature which investigates ESG in the context of risk management. Using a novel proprietary ESG methodology by Danske Bank Asset Management and credit default swaps as a measure for credit risk, a combination of pooled OLS and panel fixed-effects approach is app

Methodology: ​The study is conducted as a qualitative research, where empirical data has been collected through semi-structured interviews with Swedish new ventures. The study does further take an abductive approach in terms of the theoretical viewpoint and research perspective. Theoretical perspective: The study is based on previous research about the early phases of new ventures, the importance

Social hållbarhet viktigt för att nå resurseffektivitet i smarta elnät Vad är smarta elnät egentligen? Att svara på detta är inte helt enkelt, för det finns ingen exakt definition av begreppet. Det kan dock förklaras som att elsystemet digitaliseras och blir effektivare så att det bättre passar en framtid med mer förnybar och varierande elproduktion och ökad elektrifiering. I detta arbete har detSmart grids are often advertised as more environmentally sustainable compared to their “conventional” counterparts. What is highlighted then is their potential to save energy and integrate more renewables into the grid, thus decreasing CO2-emissions. This thesis investigates two less discussed aspects of smart grids, those of circular economy and social sustainability. An initial literature review

De senaste årens tillväxt och framsteg inom cloud computing har medfört många fördelar ur ett organisatoriskt perspektiv. Företag har nu möjlighet att få åtkomst till pooler av datorresurser konfigurerade i form av servrar, lagring och nätverk, detta utan att behöva investera i dyr hårdvaruinfrastruktur. Det är dock viktigt att ta hänsyn till teknikens nackdelar och de svårigheter som kan uppstå.

Bakgrund: Magnetisk resonanstomografi (MR) relateras ofta till oro och ångest hos barn, bland annat på grund av det höga ljudet, trånga utrymmet och långa undersökningstiden, därav är sedering och generell anestesi vanligt förekommande. Barn har olika behov beroende på ålder och mognad därmed kan identifierng av icke-farmakologiska åtgärder behövas för att öka barns trygghet. Syfte: Att beskriva o

Through a postcolonial feminist perspective, this study searched to examine how The Walt Disney Company portrayed and represented parity in two of Disney's animated films from different decades based on ethnicity, gender, and social status. Film have previously been a very useful approach when it comes to feminist research as it offers the researcher to analyze the underlying sentences of the

Abstrakt Bakgrund: Cerebral pares (CP) är en permanent skada som utvecklas innan två års ålder som begränsar barnets funktions- och aktivitetsförmåga. Barn och ungdomar med CP i grund- och gymnasieskolor upplever att skolmiljön inte är anpassad efter deras särskilda behov. Syfte: Att undersöka hur skolmiljön i grund- och gymnasieskola påverkar delaktighet i skolaktiviteter hos barn och ungdomar meAbstract Background: Cerebral palsy (CP) is a permanent injury that develops within the age of two, and permanently impairs the child's functional and performance abilities. Children and adolescents in mainstream primary- and secondary school experience that the school environment is not adapted to their special needs. Purpose: To explore how the school environment in primary- and secondary sc

Syftet var även att undersöka skillnader mellan universitetsstudenter som läser olika program och fristående kurser i en svensk population. Slutligen ämnades predicering av prokrastinering utifrån ovan nämThe aim of the present study was to examine the correlations between procrastination and several psychological variables; stress, coping, academic motivation, self-efficacy and sense of coherence. Furthermore, the purpose was to examine differences between university students who are studying different educational programs and independent courses in a swedish population. Lastly the aim was to exam

Despite the fact that a great majority of experts predicted that religion would lose its power and influence, we are currently experiencing a worldwide revival of religious sentiments. The purpose of this study is to investigate how religion, politics, and security impact identity construction in France and Turkey. This study used critical discourse analysis and thematic narrative analysis to exam

Polyamide 6 (PA6) is known to absorb water from its environment due to its chemical structure. The water absorption leads to changes in the mechanical properties as well as an increase in volume (swelling) of the polyamide. In this work, the sorption and diffusion of water vapor are investigated through gravimetric experiments and numerical simulations. The mixture theory framework is adopted to d

The Syrian crisis has forced around five million Syrian refugees to flee their homes and cross the borders to seek asylum in other countries. Most of those refugees live in neighbouring countries, and their only viable option is local integration and full participation in the economic and social life in the host countries. This thesis is a comparative study between Amman and Istanbul to examine ho

Thesis purpose: The purpose of this study is to understand what impact social media influencers have on consumers' online behaviour. We further aim to understand the interrelationship between social media influencers and online impulse buying behaviour. Methodology: This study has utilised a qualitative methodology based on a social constructionist philosophical position. The study has adopte

In this paper regularization of the correlation matrix between futures contracts is examined. With starting point in the recently established HPCA framework (Avellaneda, 2019), a couple of different extensions to the one-factor model is suggested. Extensions are made in terms of adjusting the model according to different cluster structures. The data consists of futures contracts on a wide variety
