This thesis explores the possibilities of integrating semantic transport information in the context of 3D-city modelling by implementing transport surfaces according to standards defined by the 3CIM specification, an extension of CityGML. This approach aims to automatically generate transport surfaces in LOD1 and LOD2, based on the Stockholm city basemap in combination with road geometries that re

This thesis was conducted to explore the capacity of West Slavic culture’s influence on that of early medieval Denmark from the 9-12th centuries through the examination of artifacts from both camps. Through the methodological observation of Danish and West Slavic material culture, their contexts and their connectivity between West Slavs and Danes, I apply assemblage and actor network theory (ANT)

Lake ecosystems are increasingly affected by climate change, leading to prolonged periods of elevated water temperatures. This warming reduces surface water density, intensifying thermal stratification and trapping cold water in deeper layers. Consequently, cold-water fish and other organisms are confined to limited deep-water habitats. Understanding lake thermal structure is crucial for effective

Mellan övervuxna spår, väderbitna tegelfasader och tomma hallar undersöker vi i detta examensarbete kraften i postindustriella platser, inte som statiska element från det som varit, utan som en generativ grund för det som kan komma att bli. Vi rör oss i spänningsfältet mellan bevarande och förnyelse, där vårt arbete ifrågasätter dualiteterna gammalt/nytt, produktion/boende och minne/utveckling, vBetween overgrown tracks, weathered brick facades and empty halls, this thesis explores the power of post-industrial sites, not as static elements of the past, but as a generative basis for what might be. We operate in the tension between preservation and regeneration, where our work questions the dualities of old/new, production/living and memory/development, which often characterise discussions

Today, buildings account for approximately 30% of worldwide energy use, with HVAC (Heating, Ventilation, and Air Conditioning) systems representing nearly 40% of that total. Improving the energy efficiency of HVAC systems is therefore essential for reducing operational costs and mitigating environmental impact. Because HVAC systems operate continuously and under strict operational constraints, acc

Accurate monitoring of dissolved organic carbon (DOC) in lakes is essential for understanding aquatic carbon dynamics, assessing lake ecosystem health, and supporting water resource management. While remote sensing offers scalable alternatives to in-situ monitoring, machine learning models often struggle to generalise across systems. This thesis investigates the potential of the eXtreme Gradient B

Alzheimers sjukdom, multipel skleros, amyotrofisk lateralskleros, Parkinsons sjukdom, Huntingtons sjukdom och prionrelaterade sjukdomar, är alla exempel på neuroinflammatoriska sjukdomar. Gemensamt för dessa är att det inte finns så många behandlingar tillgängliga och därmed finns det en stor efterfrågan på nya läkemedel. Neurologiska sjukdomar är svåra att behandla med läkemedel på grund av den sGalectins are proteins that bind to carbohydrate structures, with high affinity for β-galactoside ligands that exists naturally in our bodies. They are involved in the development of various diseases, including central nervous system diseases and cancer proliferation. Galectin-1, which is the focus in this thesis, is related to anti-inflammatory and neuroprotective functions in the brain. Drug del

Sociala medier har med tiden utvecklats från att vara en plattform för kommunikation och socialisering, till att även möjliggöra shopping och tillfredsställa olika konsumtionsbegär. Genom social commerce, FOMO, impulsköp och UGC påverkas konsumenterna ständigt till att konsumera mer än vad de gjort tidigare. Sociala medier har blivit en marknadsföringsplats för många företag och har utvecklats til

Kraftvärmeverk producerar el, och levererar värme till fjärrvärmenätet. Nätets returflöde till dessa verk har generellt en relativt hög temperatur, och det finns idag verksamheter som använder sig av denna returvärme för att värma upp anläggningar och utrymmen som har värmebehov. Det finns en potential att på liknande sätt utnyttja denna för uppvärmning av växthus, vilket utgör en synergimöjlighetCogeneration plants generate electricity and supply heat to the district heating network. The return flow from the network to these plants generally has a relatively high temperature, and there are currently operations that utilize this return heat to warm facilities and spaces with heating needs. There is potential to similarly use this return heat for greenhouse heating, which presents a synergy

Kvalitetskontrollsmodell för textilåtervinning 2025 infördes en EU-lag som gjorde det obligatoriskt att sortera textilavfall separat. Här presenteras grunden för en modell som relaterar reaktorparametrar till kvalité på återvunnen textilmassa. Textilindustrin omfattade 2024 knappt 2 biljoner USD. Det är en global industri där textilierna ofta designas i USA, produceras i asiatiska länder och slutTextile recycling is highly needed as great amounts of waste are produced every year and most of it is put into landfill or incinerated. This thesis lays the foundations for a quality control system which may be applied for controlling the recycling of cellulosic textiles in an upcoming pilot plant based on ShareTex’s technology. The quality control system was constructed as a mathematical model r

Disparities in health is a common issue in society, with people of different socioeconomic backgrounds having different possibilities in terms of achieving a good level of health. Stress is a common result of this, followed by insomnia and sleep impairment amongst those who are at a socioeconomic disadvantage. In this study, data was collected from multiple Swedish databases to explore whether sle

Tropiska skogar utsätts för mer intensiva och frekventa torkor. Torkor påverkar tillväxt och kollagring i skogen, samt ökar risken för trädödlighet. Det finns flera hypoteser om mekanismerna bakom dödlighet under torka. Två av de vanligaste är något som kallas kolsvält och kavitation. Det är oklart vilken av dessa två mekanismer som inträffar först i tropiska träd under långvarig torka. ExperimentTropical forests experience more intense and frequent droughts. Droughts affect mortality in trees, growth rate and carbon storage in the forest. There are several hypotheses of the mechanisms behind tree mortality during drought. Two of the most common ones are carbon starvation and hydraulic failure. It is unclear which of these mechanisms occur first in tropical trees during long term drought.

Battery energy storage systems (BESS) are becoming increasingly important for storing energy, particularly renewable energy, and stabilizing electricity grids. These systems often use lithium-ion batteries, which are efficient but pose risks during accidents. Rapid implementation of BESS has led to uncertainties in regulations and emergency response protocols. This thesis aims to identify and eval

Radar has come a long way since its invention in the 1930s. It is not only used to detect the distance and angular position of a target but can also measure velocity thanks to the Doppler frequency shift. In more advanced systems, the radar can perform tasks such as imaging and classification of the target. In some cases, full or partial polarimetry is used to gain additional information about the
