Antennas are fundamental components in the evolution of wireless communication systems, including current 5G networks and emerging 6G technologies. This thesis presents the design, simulation, and experimental validation of two antennas specifically developed for integration into repeater-assisted MIMO (Multiple Input Multiple Output) systems. These systems aim to enhance spatial multiplexing and
The purpose of this qualitative study is to explore how the Swedish community support organizations BUFFF and Solrosen support children and youths with incarcerated parents with a focus on how they address stigma, provide safe spaces, and help prevent intergenerational criminality. Through semi-structured interviews with professionals from both organizations, this thesis examines how these childre
This paper provides a critical analysis of Harry G. Frankfurt's seminal theory of bullshit, as outlined in his works "On Bullshit" and "On Truth." The thesis establishes Frankfurt's central argument that the defining characteristic of the bullshitter is an indifference to the truth, a quality that fundamentally distinguishes the bullshitter from the liar, who actively e
Onboarding is a critical and strategically important process that significantly affects an organization's ability to attract, retain and engage new top talents in today’s competitive and rapidly evolving labor market. Despite a vast amount of research emphasizing the importance and benefits from having a structured onboarding process, many organizations continue to rely on outdated strategies
This study examines the paradoxical public support for President Rodrigo Duterte's War on Drugs (WOD) in the Philippines (2016-2022) despite widespread evidence of human rights violations and extrajudicial killings (EJKs). Through a socio-legal lens and employing Stanley Cohen's "States of Denial" framework, this research analyzes how Duterte's public rhetoric justified, norm
The purpose of this research was to explore the relationship between war and media in the context of the Israel-Hamas war, which broke out after Hamas attacked Israel on October 7th, 2023. The textual news content of two sources were selected for analysis, CNN, in the first three months of conflict, and IRNA, in the first week of conflict. An exploratory mixed methods research was devised for unde
This thesis investigated the possibilities to automate the manual RTL power estimation flow for digital ASICs in Ericsson. The goal being to detect whether predefined power test cases that run with a single randomization seed are sufficient or if a multitude of seeds in an automated power flow could be used to detect scenarios with even higher activity. In order to automate the power estimation fl
Constipation and irregular bowel movements are a daily challenge in elderly care, especially among patients with dementia who struggle to report their own toilet habits. This thesis investigates the possibility of using millimeter-wave pulsed coherent radar to passively monitor toilet visits and estimate both stool consistency and excreted quantity of urine and feces. This involved constructing a
Klimakteriet eller kvinnors övergångsålder, är ett ämne som fått stor uppmärksamhet i svensk media under de senaste fem åren och för närvarande hävdas att 1,3 miljoner svenska kvinnor berörs av klimakteriet. Klimakteriet beskrivs i media som ett fenomen, som inte bara påverkar kroppen, men även känslolivet. Syftet med uppsatsen är därför att undersöka vilka diskurser om som förekommer om klimakter
This study investigated the associations between acculturation orientation and perceived social support on mental health outcomes specifically anxiety and depression among international students in Sweden. Grounded in acculturation theory, the research aimed to assess whether different acculturation orientations (assimilation, integration, separation, marginalization) significantly associate with
Denna avhandling undersöker konceptet Rolling Magnet Energy Harvester (RMEH), en kinetisk energifångare, baserad på principerna för elektromagnetisk induktion. RMEH är utformad med fraktcontainrar i åtanke och utnyttjar energin från fordonets rörelser för att driva potentiella sensorer ombord. Det långsiktiga målet är att förbättra logistiken genom att tillhandahålla en enkel, hållbar och underhålThis thesis investigates the concept of a Rolling Magnet Energy Harvester (RMEH), a kinetic energy harvester based on the principles of electromagnetic induction. Designed with shipping containers in mind, the RMEH harnesses energy from the rolling motion of vehicles to power potential onboard sensors. The long term objective is to enhance logistics by providing a simple, sustainable, and maintena
This study provides a simulation-based comparison of two energy storage alternatives, lithium-ion battery storage and a timer controlled domestic hot water (DHW) tank, within a Swedish residential context. The timer strategy explores the use of low-cost thermal storage to reduce electricity costs, especially in light of changing photovoltaic (PV) incentives. Different scenarios are modelled to com
The purpose of this thesis is to cover the definition and basic properties of the Hausdorff measure and treat the proofs of Davies and Cordoba of the Kakeya conjecture in R^2. The conjecture states that any compact set in R^2 containing a line in every direction has Hausdorff dimension 2. Using mainly basic measure theory we construct the Hausdorff measure and develop relevant theorems, such as Ma
5-Hydroxymethylfurfural (HMF) is a versatile bio-based platform chemical that can substitute fossil-derived intermediates in polymers, solvents, and fuels, thereby contributing to a fossil-free chemical industry. While first-generation feedstocks such as high-fructose corn syrup have been widely studied, their use raises concerns about competition with food supply. In contrast, second-generation r
With the rapid evolution of semiconductor technology and the growing demand for high-performance, low-power System-on-Chip solutions, the design of efficient and scalable on-chip interconnect architectures has become a critical challenge in modern ASIC development. This thesis focuses on design space exploration of replacing multiple ARM CoreLink NIC-400 crossbar-based interconnects with a unified
This project explores how design can humanize the act of sound recording by shifting focus away from performance- and technology oriented design solutions. Through user research and an in-depth analysis of the current market, human-centered design principles were identified, highlighting the importance of intuitive controls and direct feedback in handheld audio devices. The findings highlight a gr
This paper explores identity, personhood and sickness through a postcolonial lens in regards to the literary pop-cultural zombie in the 21st century. The zombie figure is studied in regards to theories of "the other" and "othering" as well as sociological and literary theories about illness, the paper thus falls within the field of medical humanities. Questions about identity,
Power amplifiers play a crucial role in wireless communication systems. However, they can achieve high efficiency only when operating in the nonlinear region. To maintain linear output while operating in this region, several techniques have been developed, among which digital pre-distortion (DPD) is one of the most widely used. In this thesis, we designed and analyzed a digital predistortion (DPD)
