Here we present a solution for debugging compilers that use abstract-syntax trees as their internal structure. The solution focuses on capturing one specific state of the compilation process, and should not be confused with the more known step-by-step debugging. The goal is to visualize the current state of the abstract-syntax tree and present its data to the user in an intuitive and interactive w
The purpose of the thesis is to examine the evidence for druids and their actions in classical texts and archaeological finds. Initially the materiality and description of druids in the classical sources will be analysed. It will be followed by an analysis of a selection of archaeological finds that researchers have connected to druids. Finally, the archaeological material will be discussed in ord
Med växande miljöhot så blir det allt mer viktigt att vi alla minimerar vår miljöpåverkan. För att förenkla detta har vi utvecklat en app som kan räkna ut miljöpåverkan genom en användares bankutdrag.Many people want to know the socio-ecological impact of the goods they purchase. In this thesis, we describe a system that computes the socio-ecological impact of those goods by analyzing uncategorized financial transactions. The computation is made possible by extending a system that can computate socio-ecological impact from categorized transactions. The extension further includes visualizations
The aim of this study is to explore narratives on violence in lesbian relationships. The study seeks to explore how stories and the act of storytelling can be used as a means to investigate a topic that has been discounted by focusing on the conditions and limitations for speaking. The study consists of both a personal narrative about being in a relationship with violence and community-based persp
Ponds are important aquatic ecosystems despite their small size. They provide the same ecosystem services and benefits than bigger waterbodies. Here I compared 18 ponds from southern Sweden to see what effect fish presence has. To establish this, the macroinvertebrates community was studied. The results show that there is a possible effect of fish size in the abundance and diversity of this commun
The paper investigates data on purchasing price of wheat from Swedish grain buyer Lantmännen and MATIF future contracts on milling wheat in an attempt to replicate the conditions for a Swedish farmer trying to manage his risk on wheat by trading future contracts on the MATIF exchange. Two static linear regressions and four dynamic GARCH models are employed on a sample of 1679 daily returns and 339
This study examines the pro-trade effects of immigration on Swedish exports. Beginning in the theory that immigrants through their unique set of networks and knowledge can facilitate international trade and bridge informational barriers to trade, this study will estimate the immigration effect on exports for Sweden. Unlike studies in similar settings, this paper applies a Pseudo poisson maximum li
De sällsynta jordartsmetallerna är en grupp av grundämnen som används mycket i elektronik och som finns med på EUs lista över kritiska råvaror. Utanför Riddarhyttan i Bergslagen, Sverige, finns en känd mineralisering av sällsynta jordartsmetaller i den metavulkaniska berggrunden. Genom att ta prover och analysera mineral som monazit och zirkon med hjälp av en metod som kallas Laser Ablation InductThe geochronology of felsic metavolcanic rocks hosting the Bastnäs-type rare earth element (REE) mineralization in the Riddarhyttan area in the Bergslagen region, Sweden, was investigated using Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) U-Th-Pb on zircon and monazite. U-Pb data from four host rock samples yield dates of 1899 ± 4 Ma (MSWD=2.2), 1910 ± 5 Ma (MSWD=3.2), 1
There are spatial elements and factors in every social activity. Physical environment in particular and its characteristics has a significant effect in the social decisions and outcomes of a location and of the residents of disadvantaged areas. These spatial elements and factors have been the main focus in many researches and studies about young people’s socio-economic statuses and achievements. T
Biokol - vägen till ett mer hållbart jordbruk? Ett sätt att minska mängden koldioxid i atmosfären är att binda kol till marken. Detta kan man göra genom att tillsätta biokol till åkermark. Biokol är en produkt av organiskt material som förkolnats genom upphettning i syrefria eller syrefattiga förhållanden, en process som kallas pyrolys. Biokol binder inte bara kol utan kan även öka den närings- Nitrogen leaching from modern agriculture can contribute to nitrogen enrichment in ground- and surface water, causing negative health effects or environmental issues by eutrophication. One technique to manage and reduce the nitrogen losses from arable land could be to apply biochar, a solid charred material that is produced from pyrolyzed biomass. Biochar has previously been shown by recent studie
A negative long-run relationship between inequality and growth has been found for a variety of inequality measures, but as these measures invariably ignore the pro-poor effect of in-kind redistribution, one may question the reliability of previous studies’ inequality-growth estimates. In this paper, I incorporate in-kind benefits into the Gini index and present new estimates of the inequality-grow
The NDVI time-series consist of trend, season and noise. Changes in the season component are related to climate factors and they happen gradually over long period of time. The changes in the trend component are often due to human activities, fires and etc. This paper implements two algorithms (PolyTrend and DBEST) in R language, in order to examine the vegetation changes in the Middle East and to
Utveckling av en metod för att kartera högsta kustlinjen i Sverige med hjälp av brytlinjer extraherade från högupplösta höjdmodeller Högsta kustlinjens (HK) geografiska läge i landskapet markerar gränsen mellan subakvatiskt och supraakvatiskt avsatta sediment. Idag varierar HKs höjd över havet från några få m.ö.h. i Skåne till omkring 289 m.ö.h. i Ångermanland på grund av den glacialisostatiska lDevelopment of a method for mapping the highest coastline in Sweden using breaklines extracted from high resolution digital elevation models The geospatial position of the highest coastline (HCL) defines the boundary between subaquatic and supra-aquatic deposited sediments. Today the HCL is located at different elevations throughout Sweden, a few m.a.s.l. in southern Scania to around 289 m.a.s.l.
Personal computers have gained a significant boost in computational power and digital storage space at a reduced cost in the last decade. In the search of increased programmer productivity and cross platform portability, language popularity has shifted from lower level languages such as C to higher level languages such as Java and C#. Many of today’s embedded systems are experiencing the same deve
Gastric ulcer is a common disorder in horses. A known potent inhibitor of gastric acid secretion is omeprazole. This thesis describes the study of omeprazole extraction followed by a high-performance liquid chromatography (HPLC) method for the quantification of omeprazole in enteric-coated pellets (raw material) and in oral paste (final drug product) for horses. The drug product is composed by a p
My master’s thesis project is an exploration of how a new distributon model could be implemented in a swedish local food chain in order to make local food accessible and attractive to a larger group of people. The interest in local food is increasing rapidly in Sweden. Farmers are turning directly to consumers for increased profit and less pressure from the industry. At the same time consumers ar
