This thesis investigates the possibilities for simulating spray cooling in pressurizer systems in pressurized water reactors (PWRs) using OpenFOAM. Spray cooling in pressurizers is part of the mechanism for regulating the pressure. The multiphase flow associated with the process is highly complex and difficult to study experimentally due to harsh operating conditions. An improved understanding of

This thesis, informed by feminist security studies, decolonial theory, and governmentality, critically examines how women’s security is discursively conceptualized, governed, and operationalized within the United Nations Mission in South Sudan (UNMISS). It argues that UNMISS protection regimes do not merely respond to pre-existing insecurity, but actively construct women’s security through gendere

This project explores how urban design can support a more inclusive, walkable and caring neighbourhood for older women in Copenhagen. Located in Refshaleøen, the project uses independently living women aged 65–75 as a critical lens for rethinking future urban development. The proposal focuses on everyday needs often overlooked in conventional planning, including slower movement, rest, safety, acc

This thesis investigates the empathic relation between the audience, as the experiencing subject, and narrative characters of a fictional story, by introducing the concept of narrative empathy. A part from elaborating this concept, the thesis seeks to empirically investigate how two different media, film and novel, modulate this relationship and which narrative categories (perspective, direct spee

Forskning har visat att kyrkans funktion inte endast är religiös. Sekularisering har påverkat olika samhällen och länder på olika sätt, i Sverige har dock sekularisering lett till att kyrkan har allt mindre betydelse som en religiös institution. Med denna bakgrund är syftet med denna uppsats att undersöka motivationen bakom ungas engagemang i Svenska kyrkan. För att undersöka detta ställs frågestä

This dissertation investigates the reliability boundaries of optical photothermal infrared spectroscopy (O-PTIR) for semi-quantitative β-sheet analysis and its application to the detection of Parkinson’s disease (PD)-related skin biomarkers. The work is divided into two sub-projects. Sub-project I used atomic force microscopy–infrared spectroscopy (AFM-IR) as a reference technique to systematical

Wheat straw is known for its complex lignocellulosic structure when it comes to its conversion to biogas using anaerobic digestion (AD). This limitation comes from the restriction of microbial hydrolysis, which results in low methane yields. For this reason, pretreatments have been studied for the purpose of enhancement of biodegradability of straw before proceeding with anaerobic digestion. This

This qualitative study investigates ecological, socioeconomic and governance-related factors that need to be accounted for in order for artificial coral reefs to be perceived as successful. The study is conducted through semi-structured interviews with local stakeholders in Zamboanguita and Dauin in the Philippines with non-profit organizations, representatives of the municipality of Zamboanguita,

Parvalbumin (PV) interneurons are specialised inhibitory neurons that help regulate the timing and balance of neural circuits. Generating PV-like interneurons through direct glia-to-neuron reprogramming is therefore relevant for disease modelling and future regenerative strategies, but efficient acquisition of a specific PV-associated fate remains challenging. This thesis builds on a human glia-to

The internal structure of the scalar meson f0 (980) remains an open question, with competing interpretations as a conventional qq ̄ state, a tetraquark, or a loosely bound K +K − hadronic molecule. This thesis investigates the molecular hypothesis through a Monte Carlo coalescence calculation applied to proton–proton collisions at √ s = 5.02 TeV. Kaon phase-space distributions are generated with P

Purpose: This study investigates whether a novel 'Human-made, AI-enhanced' label preserves consumer trust in generative AI advertising under EU AI Act transparency requirements. By comparing this hybrid phrasing to standard disclosures, the research examines how signaling human effort preserves consumer trust. Theoretical Perspective: This study is grounded in effort heuristic theory, exa

Studien ämnar undersöka hur konspirationsteorier konstrueras, omformas och upprätthålls genom interaktioner på onlineforumet Reddit med inriktning på diskursen kring Jeffrey Epstein. Vidare är syftet att undersöka hur konspirationsteorier interaktionellt utvecklas genom plattformens användare. Studien utgår från ett interaktionistiskt och kunskapssociologiskt perspektiv där konspirationsteorier fö

Reliable ankle torque measurements are important in rehabilitation, where strength assessments are used to evaluate recovery and guide treatment. Isokinetic dynamometers, such as the Biodex system, are commonly used to provide controlled measurements of joint torque. However, these measurements rely on the ankle being held in a stable and reproducible position. Mechanical play in the ankle-attachm

Future sixth-generation (6G) wireless systems are expected to support extreme data rates, massive connectivity, and high energy efficiency. Largescale Multiple-Input Multiple-Output (MIMO) combined with Orthogonal Frequency Division Multiplexing (OFDM) is a key enabling technology to meet these demands. However, OFDM signals exhibit a high Peakto- Average Power Ratio (PAPR), which forces power amp

This thesis investigates the applicability of using machine learning for demand forecasting at HMS Networks. Using the design science research methodology, multiple forecasting artifacts were developed and tested iteratively, using historical sales data. Four tree-based models; Decision Tree, Random Forest, LightGBM and XGBoost, were tested with different pre-processing and feature engineering tec

With approximately 94 percent of traffic accidents being caused by human error, improving driver behaviour has the potential to save lives. To encourage safer driving, Volvo Cars is developing a Safety Coach feature for their mobile application. However, pilot studies of a minimum viable product (MVP) indicated low user retention, suggesting the need for design elements that better support user en

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
