This thesis examined the impact of the COVID-19 lockdown on Athenian air quality from March 23rd to May 5th, 2020. The Attica Ground Measuring Network was used to measure the concentrations of NO, NO₂, SO₂, CO, PM₁₀, PM₂.₅, and O₃ for the 2020 lockdown and for the same time period from 2005 to 2019 as reference. Nitric oxide (NO) and nitrogen dioxide (NO₂) concentrations decreased by up to 75% an
The global energy transition and the growing adoption of electric vehicles drives an ever-increasing demand for more efficient electrical machines. A key improvement area is understanding and reducing iron losses in machine magnetic materials, such as those caused by Pulse Width Modulation (PWM). This thesis investigates the effects of PWM on magnetic hysteresis and the resulting iron losses in Fe
Syftet med denna uppsats är belysa hur utrikesfödda kvinnors etableringsprocess ser ut på den svenska arbetsmarknaden, med särskilt fokus på hur integration, inkludering och hur stereotypa föreställningar påverkar deras möjligheter att etablera sig på den svenska arbetsmarknaden. Studien avgränsas till kvinnor födda utanför Europa. Genom ett intersektionellt teoretiskt ramverk, med fokus på kön, e
This thesis explores how femininity is constructed within the soft girl trend, using Butler’s theoretical framework of the heterosexual matrix and theory of (gender) performativity. By combining digital ethnography, multimodal critical discourse analysis, and a critical feminist perspective, this study aims to contribute to a deeper understanding of how femininity is expressed, reproduced and aest
This thesis investigates two-particle pseudorapidity correlations in proton-proton collisions at sqrt(s)=13 TeV at the ALICE detector at the Large Hadron Collider. The primary focus is on the calculation of the correlation function in pseudorapidity across different multiplicity classes and charge combinations. Subsequently, efficiency corrections were applied and studied within Monte Carlo simula
Syftet med detta examensarbete var att klargöra vilka statistikkällor innehållande arealuppgifter för jordbruksmark som finns åtkomliga samt att undersöka skillnaderna mellan de olika källorna. Intentionen var även att komma fram till förslag kring hur inhämtningen av taxeringsuppgifter vid fastighetstaxeringen kan förenklas respektive underlättas för fastighetsägare samt hur andra statistikkällorIn Sweden, the National Tax Board produces tax assessment values for all properties. This value is based on information obtained by the property owner during the property tax assessment and on the National Tax Board's developed guideline values. It is the value factors area, condition and drainage that affect the value. This thesis examines how the area data for agricultural land in different
Modern cellular radio base stations (RBS) employ beamforming to dynamically steer radio frequency (RF) energy toward active users. This adaptive transmission produces significant angular and temporal variations in the equivalent isotropically radiated power (EIRP). To account for these variations, electromagnetic field (EMF) compliance assessment of RBSs rely on the usage of the EIRP envelope toge
Landskrona är en stad i pulserande förändring. Staden, som har sina historiska rötter i såväl indus triarbete som kolonilotter, har under det senaste de cenniet utmanats med ett allt mer förändrat stadsliv. En stad som tidigare haft svårt att hyra ut sina mest centrala bostäder upplever nu ett ökande intresse för att bo och vistas i staden. En förändring som, om än synlig idag, kommer fortsat
Political violence in Athens exhibits distinctive spatial and temporal regularities shaped by the city’s symbolic infrastructure, mobility patterns, and socio-political dynamics. This thesis integrates environmental criminology with spatially explicit machine-learning techniques to examine risk patterns of politically motivated violence between 2008 and 2024. Using a multi-layered dataset of 610 a
Denna studie undersöker de interpretativa och tekniska krav som ställs på violinisten i Alfred Schnittkes Concerto Grosso nr. 1, med särskilt fokus på verkets dialog mellan det förflutna och nutiden. Genom en detaljerad analys av violindelarna utforskar forskningen avancerade stråk-, artikulations- och intonationsstrategier som krävs för framförandet, samt effektiva övningsmetoder. Den formella anThis study explores the interpretative and technical demands placed on the violinist in Alfred Schnittke’s Concerto Grosso No. 1, with particular attention to the work’s dialogue between past and present. Through a detailed examination of its violin parts, the research investigates advanced bowing, articulation, and intonation strategies required for performance, as well as efficient practice meth
In the easternmost Sveconorwegian Province, field studies have shown that some intrusions remained largely unaffected by the Sveconorwegian orogeny. However, seemingly pristine gabbros locally display the incipient development of amphibolite amphibolite-facies mineral assemblages in microscale corona textures. The primary objective of this study is to document in detail the microtextures that occu
The motivation to learn foreign languages is diminishing globally due to the dominance of English in business, media, and education, and additionally to the access it provides to the so-called global community and global identity. Nevertheless, smaller languages such as Swedish continue to be offered at universities worldwide, with students enrolling despite their limited societal use. This study
This thesis presents the development and evaluation of a virtual reality (VR) environment designed for integrated EEG, EMG, and joint movement data collection. The system combines immersive VR with biosignal acquisition technologies, including the Unicorn Hybrid Black EEG, the Myo Armband for electromyography and inertial sensing, and the Cyberglove for hand joint tracking. The goal was to create
Background: Magnetic resonance flow imaging is vital tool for modern cardiovascular medicine. However, it is resource intensive. Simulations can help develop magnetic resonance sequencing methods and can also facilitate use of AI models in the future by providing realistic test models to train on. Simulations of magnetic resonance imaging are often computationally demanding and the accuracy of the
Forskning om tidigare förekomster av kalkbildande nannoplankton är avgörande för att förstå deras roll i dagens klimatförändringar, samt för att kunna fastställa tidpunkten för deras uppkomst. Denna forskning begränsas dock av begränsat bevarande av nannofossil. En proxy för abundans av kalkbildande nannoplankton skulle därför vara användbar. Eftersom kalkbildande nannoplankton är idag de största Research of past calcareous nannoplankton abundances is essential for understanding their role in climate change of today, as well as being able to constrain the timing of their emergence. This research is however limited by preservation issues of nannofossils. A proxy for the abundance of calcareous nannoplankton would thus be useful. As calcareous nannoplankton are the largest producer of calciu
Arbetets syfte är att genom intervjuer ta reda på hur viktigt samverkan och företagsamhet är för alla musiker och kompositörer. Hur hör detta ihop med lyssnande och samverkan i repetitions- eller konsertsalen? Vad tycker dirigenten är viktigt för att driva en orkesterrepetition framåt? Vilken väg ska en kompositör gå för att komma i kontakt med konserthusen? Med intervjuer av kollegor och professoThe aim of the work is to find out through interviews how important collaboration and entrepreneurship are for all musicians and composers. How does this relate to listening and collaboration in the rehearsal or concert hall? What does the conductor think is important to drive an orchestral rehearsal forward? What route should a composer take to get in touch with concert halls? Through interviews
In this thesis, we evaluate the side-channel security of the NIST HQC post-quantum cryptosystem by analysing the official FPGA decapsulation implementation. A hardware wrapper was created to interact with the HQC decapsulation modules, enabling ciphertext decapsulation with precise power trace capturing using a ChipWhisperer CW305 and Husky setup. A dataset with 20k power traces was generated from
