This thesis analyses how the growth of wind and solar PV generation has affected wholesale electricity prices in Spain between 2020 and 2025, and how that relationship evolved as renewable penetration increased. Using 52,603 hourly observations obtained from the REE ESIOS public data portal — covering OMIE day-ahead spot prices, electricity demand, wind generation, and solar PV generation — the st
The demand for better networks and faster speeds within telecommunications has been an ever-growing ambition for the last decade. A promising candidate for dealing with this demand is distributed multiple-input multiple-output (D- MIMO) systems that combine large-scale antenna arrays and decentralized node architectures. However, evaluating the possibilities and limitations of such system requires
Smart charging of electric vehicles can reduce cost by scheduling against time-varying electricity spot prices, but commercial systems generally rely on day-ahead prices and capture only within-day variation. This thesis investigates whether forecasting spot prices beyond the day-ahead horizon adds value for vehicle-integrated smart charging, and how that value varies across charging contexts. A t
Air pockets in pressurized pipelines may reduce hydraulic capacity, increase head losses, and affect system operation. In downward sloping pipe sections, a key question is whether the water flow can transport a trapped air pocket downstream or whether the air is likely to remain stationary, which would require an air valve to evacuate the air. This thesis compares selected criteria and guidance so
Våtmarker bidrar med många ekosystemtjänster såsom kolinlagring och förbättrad vattenkvalitet och tillgänglighet. Historisk dränering har dock lett till en massiv förlust av våtmarker världen över, vilket resulterat i förlorade ekosystemfunktioner och ökade utsläpp av växthusgaser. Idag finns ett ökat intresse för återställning av våtmarker för att nå beslutade klimat- och miljömål. Det finns dockPeatlands provide several ecosystem services such as carbon sequestration and improved water quality and availability. However, historical drainage has led to a massive loss of peatlands worldwide, resulting in lost ecosystem functions and increased greenhouse gas emissions. Today, environmental goals have led to a renewed interest in the restoration of peatlands. However, knowledge gaps regarding
The effectiveness of early warning systems (EWS) is frequently emphasised as being dependent on the integration of vulnerability, yet such considerations are often argued as lacking in practice by international organisations and scientific communities. Although this is acknowledged by global initiatives, less attention has been given to understanding vulnerability integration from the perspectives
This study examines Turkish foreign policy toward Syria through the lens of historical materialism. Departing from mainstream analyses that treat economy and politics as separate spheres, it situates class dynamics at the core of foreign policy formation, arguing that Ankara's engagement is systematically driven by the imperative to convert conflict into economic opportunity for Turkish capita
This research examines the racial and gendered dynamics of dancehall culture in Sweden, focusing on how participation in a transnational Black cultural practice shapes relationships between white women and racialized women within predominantly female dance spaces. Originating in Jamaica, dancehall has expanded globally, becoming both a site of cultural expression and a commodified transnational pr
Projektet “Passage som Metod” undersöker hur befintliga strukturer kan transformeras för att stärka stadens offentliga rum. Med utgångspunkt i en ingående kartläggning av ett centralt kvarter i Landskrona identifierades en outnyttjad potential i samspelet mellan befintlig bebyggelse, vertikala relationer och stadsrummet. I den här rapporten presenteras processen från början, som till sist leder p
Electromagnetic compatibility (EMC) is essential for power electronic converters to prevent electromagnetic interference (EMI). Traditional post-design EMC testing is costly and time-consuming, motivating a shift toward model-based EMC (MB-EMC) with proactive EMI prediction. This thesis develops a simulation methodology for conducted emissions from an IGBT-based three-phase voltage source converte
Various devices rely on invasive biometric identifiers, such as voice and facial recognition, raising privacy concerns. Acoustic handclap control presents a privacy-preserving alternative for interaction with computers, as it does not capture speech or visual data. An analysis of the original implementation suggested that existing classifiers were influenced by environmental bias. With the objecti
Bakgrund - Samarbete mellan offentliga och privata aktörer är avgörande för livsmedelsberedskap, men tidigare forskning visar att implementeringen av samverkansmekanismer kan påverkas av organisatoriska, relationella och institutionella faktorer. Det finns behov av ökad förståelse för hur dessa mekanismer fungerar i praktiken. Syfte - Syftet med studien är att undersöka vilka samverkansmekanismerBackground - Collaboration between public and private actors is crucial for food preparedness, but previous research shows that the implementation of collaborative mechanisms can be influenced by organizational, relational, and institutional factors. There is a need for increased understanding of how these mechanisms function in practice. Purpose - The purpose of the study is to examine which col
In supplier sustainability management today there is a gap between the volume of compliance work that stricter EU regulation imposes on companies and the manual methods available to handle it. The consequence is that gap analyses between a buyer's Supplier Code of Conduct (SCoC) and the documents provided by suppliers are postponed or left undone, leading to long lead times and bottlenecks in
This study examines how organisational actors within a manufacturing firm recognise and navigate AI readiness factors during AI initiatives. Existing research identifies which readiness dimensions matter but offers limited understanding of how these dimensions are recognised and managed in practice. The study was conducted as a single case study of SKF Group, based on nine semi-structured intervie
Magnetomotive ultrasound (MMUS) is a developing imaging modality using magnetic nanoparticles (MNPs) as contrast agent. MNPs are accumulated at a tissue target and set in motion by a time-varying magnetic field. The resulting displacement spreads to surrounding tissue and is detected with ultrasound. The objective of this modality is to transition medical ultrasound from structural to molecular sp
Surface electromyography or sEMG is universally used as a control signal in myoelectric prosthetic hands, where muscle activation patterns are utilized to interpret the user's intended movements. However, sEMG recording quality is strongly affected by electrode-skin interface, electrode configuration and even external factors such as limb position. Traditional rigid electrode setup with limite
Continuous non-invasive monitoring of respiratory rate in laboratory mice can support research across drug efficacy, sleep, and stress and pain assessment. Established respiratory rate estimation methods exist but many conflict with the 3Rs principle through invasiveness, motion restriction, or animal stress. A cross-method comparison between two non-invasive systems on the same freely-moving anim
In this project a tool for valve flow quantification from 4D flow data for the mitral and tricuspid valves was developed and integrated into the clinical image analysis software Segment. The pre-implemented neural networks MVnet and TVnet were used for tracking the valves in 2CH and 4CH cine MRI images. The positions of the valves were used to create planes in the 4D flow data to measure flow over
Four-dimensional flow magnetic resonance imaging (4D flow MRI) enables time-resolved assessment of intracardiac blood transport, but quantitative analysis requires workflows that convert complex velocity data into consistent and interpretable measures. This thesis aimed to develop and evaluate a semi-automated workflow in Segment for quantitative left-ventricular (LV) flow-component analysis. The
ygg- och anläggningssektorn står inför växande utmaningar kopplade till resurser, klimatpåverkan och tillgången till jungfruliga ballastmaterial. Samtidigt har omställningen mot en mer cirkulär ekonomi ökat intresset för återvunna material såsom slaggrus från avfallsförbränning. Trots dokumenterade tekniska egenskaper och flera framgångsrika tillämpningar i Sverige och utomlands är användningen av
