The number of low-cost particulate matter (PM) sensors available on the market has increased in recent years. They are affordable, compact and require no maintenance which means they easily can be deployed and utilized for real-time air monitoring. However, the accuracy of low-cost PM sensors has been reported to vary depending on several factors. This thesis aims to investigate and reduce errors

Fulufjället, Dalarna. Projektet handlar om att designa ett museum där platsens olika kontexter i natur, vind, snö och ljus ligger i huvudfokus för utförandet, med utgångspunkten att vara obemannat och ta hand om besökaren på bästa möjliga sätt.

Purpose: In the setting of a large Swedish media organisation, the purpose of this study is to create an understanding of how internal factors (strategy, organisational structure and culture) affect the organisation's ability to handle ambidexterity and how the factors interrelate. Methodology: A qualitative single case study was conducted, from multiple levels within a large Swedish media o

In this study we have examined how fathers experience and construct fatherhood in relation to equality, masculinity and fatherhood ideals. With the backdrop of Sweden’s comparatively progressive equality and parenthood politics we have conducted seven semi-structured qualitative interviews with Swedish fathers aged 25-35. We have analysed the material using categorical content analysis with theore

Informal green spaces are “small green areas” which are some square meter plots along streets or in junctions, in front of public or private buildings. Informal urban green space become or remain in neglected condition due to the lack of capacity of the municipality to maintain them. Further, there is a lack of responsibility, competency and motivation of the residents to voluntarily take care of

This work investigates, from an architect’s perspective, images of the forest as a space and as a resource. In a personal exploration, the author’s own relationship to forests, as well as cultural and scholarly conceptions of what the forest is and means are examined and questioned, connected and contrasted. Seemingly uncomplicated popular images that are shaping our view of the forest as well as

This paper explores the use of an automated pipeline to construct synthetic (artificially derived) trip data from aggregate socio-demographic sources to build a simulation of individual vehicles interacting with one another. The study shows that quality data sources are required in order to do this effectively and accurately. It is shown that aspects of typical patterns and behaviours may still n

I Sverige utgörs majoriteten av våra grundvattenresurser av isälvavlagringar i form av rullstensåsar och isälvsdeltan bestående av sand och grus. Isälvsavlagringarna är utan tvekan de mest betydelsefulla grundvattenförekomsterna för Sveriges dricksvattenförsörjning. Mer än 80% av landets alla vattenverk utnyttjar vatten från dessa resurser. En ojämn fördelning av grundvattenresurserna i kombinatioMost of Sweden’s groundwater resources are made up from glacifluvial deposits such as eskers and deltas that consist of sand and gravel. Glacifluvial deposits are certainly the most significant groundwater resources for drinking water supplies in Sweden. Groundwater resources are used to supply more than 80% of all the existing water plants nationwide. These important resources have an uneven dist

Functionalization of a TB analogue through a six step synthesis has been performed, collecting valuable material for further synthesis towards a heptakis TB analogue and characterization of intermediates. Previous work in the Wärnmark group has produced this heptakis TB analogue and this project focused on following the worked out procedure and improving it where possible. The synthesis started fr

Galectins are an old fifteen-member protein family. Every galectin has one or two highly conserved carbohydrate recognition domains (CRDs) through which it binds their mutual ligand galactose. They are involved in various pathways such as signaling, autophagy and immune response. However, they also contribute to pathological functions including fibrosis, metastasis, cardiovascular diseases and dia

När man talar om framtiden finns det ett begrepp som dyker upp i nästan varje diskussion: "articiell intelligens". Vår fascination kring framtidens potentiellt självtänkande robotar speglas i hur mycket det diskuteras i alla yrkesgrupper just nu, oavsett om ämnet är koldioxidutsläpp, självkörande bilar eller automatiska inköpslistor. Men hur långt har egentligen maskininlärning kommit idThe task of Automated Essay Scoring (AES) has been active for more than half a century, starting with handcrafting statistical features used for linear regression, and currently being improved by the latest advancements in machine learning and natural language processing. Most current research uses some form of character or word embeddings to represent the essays rather than statistical features,

Med anledning av den stora vågen av flyktingar som under de senaste åren har sökt skydd inom Europas gränser, har åtgärder implementerats för att kontrollera deras inresa, vistelse, samt utvisning. Användandet av sådana åtgärder, så som förvarstagande, har både ökat och intensifierats i dess användning. Syftet med denna uppsats var därför att fokusera på den svenska praxisen angående verkställigheDue to the large influx of persons seeking refuge within European states in recent years, measures which control the entry, residence and expulsion of aliens have increased both in use and intensity. An example of such a measure is the detention of asylum seekers for administrative reasons. The purpose of this paper was therefore to focus on the Swedish practice concerning the administrative deten

With the Internet of Things era being here, more devices than ever are connected to the Internet, making the need for higher security greater. One important aspect of security to consider is encryption, which protects data from being read by unauthorized parties. Integrating cryptographic algorithms can be done in many ways and is usually dependent on restrictions of the area, speed, and power whe

Syfte: Syftet med uppsatsen är att undersöka huruvida två olika investeringsstrategier, Magic Formula och Momentumstrategin, kan generera abnormal avkastning på den europeiska aktiemarknaden utifrån fyra tillgångsprissättningsmodeller mellan juli 2000 och juli 2018. Uppsatsens bisyfte är att undersöka hur investeringsstrategierna utvecklas i förhållande till marknadsportföljen. Metod: Metoden som Purpose: The purpose of the thesis is to examine if two investment strategies, Magic Formula and Momentum strategy, are capable of generating an abnormal return on the european stock market according to four asset pricing models during the time period between July 2000 and July 2018. A secondary purpose is to investigate the investment strategies’ performance in relation to the market portfolio. M

Dagens vägskyddsanläggningar är baserade på gammal reläteknik och är byggda på liknande sätt som på 1940-talet. År 2014 påbörjades projekt-Alex av Trafikverket med mål att byta ut dagens vägskyddsanläggningar mot en mer modern och driftsäker anläggning. Detta genom att uppdatera tekniken i vägskyddsanläggningarna till ett databaserat system som ska standardiseras och inte vara så anläggningsspecifToday's level crossing security systems are based on old relay-based technology and have been constructed in the same way since the 1940s. In 2014, Project-Alex was initiated by Trafikverket to replace the current level crossing security systems with a more modern and reliable system. It is done by updating the technology in the level crossing security systems to a computer-based system that i
