Autoencoder outlier detection during the Covid-19 vaccination campaign

Data inom hälsovården kan användas för att hitta mönster för att exempelvis ta fram hur många som är sjuka, eller hur många som har fått ta blodprov. Det används ofta statistiska modeller för att göra undersökningar, men i detta projektet används artificiell intelligens, och mer specifikt neuronnät. Då tar vi hjälp av artificiell intelligens för att hitta mönster inom datakällor som kan vara svåraOutlier detection in high-dimensional data is a complex task, useful in many fields. One major application is in healthcare, where the high-dimensional healthcare registers can be used to detect patterns related to the medical behaviour and state of the population. In this project, neural network based autoencoders were used to study the Covid-19 vaccination campaign, where it was trained on healt

Vombsjön är en sjö belägen I sydvästra Skåne som fyller en viktig roll som dricksvattenreservoar. Sjöns avrinningsområde består till ca 70% av jordbruksmark vilket har medfört långvarig påverkan på vattenkvaliteten från lokalt näringsläckage. I dagsläget finns ingen lokalt anpassad förvaltningsplan för Vombsjön utan den förvaltas utifrån den regionala förvaltningsplan som gäller för hela SödrLake Vomb is situated in the southwest of Skåne, Sweden, and is important due to its role as drinking water reservoir. The lake is situated in highly cultivated farmland and is highly influenced by nutrient rich run-off water. There is no locally adapted water management plan for lake Vomb and the lake is currently managed under a regional water management plan which covers the entire Southern B

Electric Road Systems: A case study on the bridge of Öresund

Combustion of fossil fuels is single-handedly the largest contributor of global warming. The transportation sector is responsible for about a third of the greenhouse gas emissions yearly in Sweden. In turn, road traffic makes up the largest share within the transportation. The Swedish government has set out an ambitious goal to reduce domestic carbon emissions caused by the transportation sector

Global Rankings in Swedish Universities : A Qualitative Study of Knowledge Management Practices

During the past two decades, the higher education sector has undergone rapid changes as a result of which many higher education institutions (HEIs) find themselves being compared to other institutions. Global rankings have become the prime mechanism for providing such comparisons. How nations and their HEIs respond to the developments in the higher education sector is context-specific. There is a

Spatial Patterns for Potential Climate Voting

The need to curb global warming is evident, and efficient climate policies are essential. But within the democratic context, public support for climate politics is needed to implement mitigation efforts. Sweden has long been known as a forerunner for climate change mitigation, however, there are indications that the voters’ interest in climate politics is waning. This study aims to visualize the e

Effekten av fastighetsköp via bolag − En studie i informationstillgång och transparens på den kommersiella fastighetsmarknaden

Idag sker majoriteten av alla kommersiella fastighetstransaktioner via bolag. Detta sker genom att först låta paketera fastigheterna i bolag, för att sedan avyttra aktierna i bolagen där fastigheterna ingår. Drivkraften bakom förvärvsmetoden är sänkta transaktionskostnader, främst genom skattebesparingar. Detta innebär att allt färre transaktioner sker på traditionellt vis, det vill säga som fast The trend of increasing commercial real estate transactions via companies has a negative impact on the process of estimating the taxable values. This due to the sharp decrease of comparison material for our Swedish authorities. Real estate transactions via companies also enable information about the transaction to be kept secret from outside parties. The study aims to show how various parties in t
