This thesis presents the evolution, design, and test of an Orthogonal Frequency Division Multiplexing (OFDM) based radar system. The application of this research question involves the implementation of an Integrated Sensing and Communication (ISAC) radar system that can be seamlessly integrated into existing wireless communication networks. The primary objective of this thesis project is to integr
Small interfering RNAs (siRNAs) are a rapidly growing class of oligonucleotide therapeutics that modulate gene expression by inducing targeted mRNA degradation. siRNAs are potent and their effect is long-lasting, making them promising candidates for chronic neurodegenerative disease. However, siRNAs can elicit both on- and off-target toxicity, and while acute neurotoxicity has been characterized,
High grade serous ovarian cancer (HGSOC) is accompanied by an immune-rich but heterogenous tumor microenvironment. Although tumor associated tertiary lymphoid structures (TLS) are linked to favourable antitumor immunity, B cells may also adopt spatial distribution patterns favourable for immune suppression. This study evaluated whether the abundance and spatial distribution patterns of CD20+ B cel
This thesis presents an automated pipeline developed for reconstructing the 3D flight trajectories of bats navigating a cave environment purely from multi-channel audio recordings. The pipeline was developed and validated using the Ushichka dataset which contains multiple simultaneous audio and video recordings of bats in their natural habitat, the Orlova Chuka cave in Bulgaria. The proposed pipel
Vid projektering av spontkonstruktioner används numeriska modeller för att analysera deformationer, jordtryck och moment i konstruktionen. Tvådimensionella modeller används frekvent inom geoteknisk projektering, då dessa innebär lägre modellkomplexitet och kortare beräkningstider än tredimensionella modeller. Samtidigt kan tredimensionella modeller beskriva konstruktionens verkliga beteende på ett
Denna studie undersöker vilken roll kreativitet spelar i undervisningen i musikproduktion på gymnasieskolan, samt hur projektbaserat arbete används som pedagogisk metod inom ämnet. Studien bygger på intervjuer med sex gymnasielärare som undervisar i musikproduktion. Resultatet visar att kreativitet är en central men komplex del av undervisningen. Informanterna betonar särskilt betydelsen av kreatiThis study examines the role of creativity in music production education at the upper secondary school level, as well as how project-based learning is used as a pedagogical method within the subject. The study is based on interviews with six high school teachers working in music production. The results show that creativity is a central yet complex part of the teaching. The informants particularly
Discussions surrounding Victorian author Sheridan Le Fanu’s Carmilla (1872) have explored many of the novella’s themes, including but not limited to the Gothic vampire, queer representation and historical significance. This thesis endeavours to expand the lesser developed discourse on the novella’s ending and narration by analysing Carmilla’s ending through the lens of the “bury your gays” trope,
This project involved the testing and establishment of a base combustion procedure for the newly acquired Raddec Gen IV PYROLYSER and focused on the optimization and correction of the laboratory’s previous liquid scintillation counting (LSC) procedure using the Hidex 300 SL. The pyrolyser was verified to be operational and achieve satisfactory and consistent recoveries across the 6 combustion tub
Accurate time synchronization is a fundamental requirement for industrial systems, particularly applications relying on deterministic communication and coordinated control. While the Precision Time Protocol (PTP), or IEEE 1588, can achieve a sub-microsecond accuracy in wired local networks, its performance over wireless networks such as Fifth Generation Mobile Network (5G) remains challenging due
Införandet av kvartär rening i svenska avloppsreningsverk är en följd av det reviderade europeiska avloppsdirektivet och syftar till att minska utsläppen av organiska mikroföroreningar till recipienter. Dimensioneringen av kvartär rening påverkas i hög grad av inkommande flöden, vilka varierar både över tid och mellan olika reningsverk. Särskilt betydelsefullt är valet av dimensionerande flöde sam
Dagvatten kan transportera föroreningar till recipienter, vilka kan vara skadliga för både djur, natur och människor. Dessa föroreningar inkluderar bland annat metaller och näringsämnen. En betydande källa till tungmetaller är vägtrafikrelaterad, då bland annat slitage från bromsar och däck samt galvaniserade metallstrukturer ger upphov till föroreningar. Föroreningar med fraktioner som är min
The observed matter-antimatter asymmetry in the Universe suggests the existence of baryon number violating processes beyond what is present in the Standard Model of Particle Physics. The HIBEAM programme is a proposed experiment at the European Spallation Source (ESS) that investigates baryon-number violation through neutron-antineutron oscillations. Of specific interest to this work is the proces
Ethylene oxidation over Pd nanoparticles in an ambient pressure environment was studied. While modulating the temperature in an ethylene-oxygen mixture, operando ambient pressure X-ray photoelectron spectroscopy revealed an oscillating thickness of a PdC_x layer surrounding the nanoparticles while producing CO and CO_2. Scanning electron microscopy before and after the measurement revealed the for
Recombinant protein development requires not only successful expression and purification, but also the recovery of stable and functionally active proteins. In this study, five recombinant proteins were used as case examples to examine key challenges in early-stage recombinant protein production and functional characterization. These included three oat seed lipase 1 variants, OL522, OL118, and OL18
Modern integrated circuits contain extensive on-chip instrumentation—Ring Oscillators (ROs), temperature sensors, voltage monitors, and delay-measurement circuits—originally intended for reliability monitoring and process calibration. The same physical sensitivity that makes these instruments effective sensors also makes them potential side-channel receivers. An adversary who can place or exploit
This thesis presents the design and schematic-level simulation of a highly linear mixer-first receiver front-end implemented in CMOS, targeting improved robustness against strong input signals. The proposed architecture employs a current-mode passive mixer directly loaded by a low-impedance transimpedance amplifier (TIA) in order to minimize the voltage swing at the mixer output and thereby enhanc
Microvias are key enablers of next-generation high-speed and high-density electronic products. However, their signal-integrity performance can be affected by manufacturing-induced non-idealities, including tapered sidewalls caused by laser drilling and positional staggering caused by fabrication tolerances. This thesis investigates the impact of microvia vertical geometry and manufacturing-induced
As we have become more modern, we have become more reliant on electronic devices, containing micro- and nanosize components. Coming along with more advanced and complex manufacturing methods have become more advanced, they bear plenty of inconveniences, most commonly the impossibility of printing on surfaces with arbitrary surface curvature. This issue is resolved by the reflow transfer printing m
