Wireless Power Transfer (WPT) is increasingly utilized across various practical domains, requiring continual development and optimization of supporting technologies. An essential aspect of this progress is the efficient testing of WPT Systems. This thesis explores optimization of the testing process using Machine Learning(ML) and data analysis, applied on historical data represented by test outcom

This thesis explores the state-of-the-art methods for the optimization of Wireless Power Transfer (WPT) for Radio Frequency (RF) energy harvesting with a view of increasing the efficiency of the Radio Frequency to Direct Current (RF-to-DC) conversion, which is a key parameter in the creation of Zero Energy Devices (ZEDs) in the context of Internet of Things (IoT). The research focuses on waveform

Safe and clean drinking water delivery is challenged by climate change, as elevated temperatures can promote the growth of pathogens and other detrimental microorganisms. The microbial processes underlying drinking water production in slow sand filters (SSFs) are largely uncharacterized, limiting the possibilities of improving this technology. Periodical clogging, potentially by microbes, disrupts

The dynamics of China’s complex policy process, shaped by the decentralization reforms of the 1980s, remain the subject of much discussion. As China spent three years adhering to its eradication strategy in response to the COVID-19 pandemic, it seems that the relevant theories from the past need to be updated. The purpose of this study was to understand how irrational decisions were made and why u

In this written study, I have researched video game music from the 90’s and early 2000’s to see what I can learn from the process of composing music for video games, as well as how the hardware and software capabilities of the game consoles shaped the music. First it presents my own background and relation to the subject, next it establishes what functionally separates video game music from conven

Intersections have long been recognized as high-risk areas for traffic accidents, with vehicle collisions in Non-Line-of-Sight (NLoS) scenarios resulting in significant economic and human losses. This thesis investigates a vehicle collision avoidance system that integrates Machine Learning (ML), wireless communication technologies, and sensor fusion with Global Navigation Satellite System (GNSS) p

The invaders vs. the protectors: who wins the battle? Pseudomonas aeruginosa or in short PsA is a type of microorganism, also known as “bacteria” or “germ” or “bug”. It is very tiny and invisible to our naked eyes. This germ is found everywhere in places like soil, and water. PsA can get into the human body through wounds and other injuries and make people sick. To prevent humans from getting inf

Utforskandet av nya roller av komplement proteinet C3 Komplementsystemet är en uråldrig evolutionär mekanism i det medfödda immunförsvaret och funkar som en av kroppens första försvarslinje. I detta gamla system finns det ett protein som sticker lite mer, ett protein som har en central roll i komplementsystemet, nämligen komplement protein C3. Inte nog med att den har en viktig roll i framkallninThe complement system is an ancient component of the immune system, comprising three pathways: classical, lectin and alternative pathways. Central to these pathways is complement component C3, which converges the three pathways. C3 can be enzymatically cleaved into C3a which functions as an anaphylatoxin, and C3b, which functions as an opsonin. Previously, C3 was understood as a serum protein, how

From Seedlings to Solutions: Which Test Will Sprout Success? Type 1 diabetes (T1D) is a condition in which the body attacks its own cells that produce insulin, a necessary hormone that allows us to use energy from food. People who do not have insulin are unable to process sugar effectively, which causes major health problems. Since there is currently no cure for this condition, affected individua

The mycelium enables a fungus to explore and interact with spatially and temporally heterogenous environments. It operates at a range of scales, with hyphal traits and cellular events affecting network and colony behavior. Recently, the fungal mycelium has also been used to produce new, sustainable biomaterials which can serve as alternatives to numerous non-renewable or polluting materials and pr

For decades, the Gaza Strip has been under Israeli occupation combined with reoccurring military escalations, continuously impacting Palestinian lives. On October 7th 2023 a severe escalation took place yet again, in which questions were raised surrounding the level of legality of Israel's actions. This thesis analyses the case of Israel's military operation in Gaza throughout 2023/2024, a

Inhibitory neurons or interneurons are important regulators of brain signaling. Parvalbumin (PV) interneurons, the most common interneuron subtype, have the unique ability to fire a rapid train of action potentials. They regulate the activity of pyramidal neurons to promote appropriate behavioral responses. Cortical PV interneurons’ function is greatly diminished in neuropsychiatric disorders e.g.

Many of the border regions along the Norway-Sweden border are thinly populated, rural areas, which means that the societal response to accidents, emergencies, and disasters in these regions will often have to rely on external assistance. And often the closest assistance can often be found in the municipality across the border. However, aligning the emergency management of two different countries w

Today, social media offers new possible tools for organizing and spreading political messages than in the past, changing the way activism can take shape and thereby producing new forms of records. These records make up an important part of today’s history and therefore should be preserved for the future. However, despite the possibilities that social media offers, commercial social media platforms

Att fånga upp koldioxid från industriella utsläpp eller direkt från atmosfären och omvandla det till mer värdefulla föreningar, kallat "carbon capture and utilization", är en intressant metod för motverkandet av den globala uppvärmningen. Med en katalysator kan koldioxid och vätgas användas för att tillverka metanol som är användbart som bränsle och i kemikalieindustin. En nyligen upptäcNickel gallium alloys have recently been discovered as a promising material for the catalyzation of methanol synthesis from carbon dioxide. Due to the novel nature of the material system for this purpose, there is a large potential for optimization in terms of catalytic activity and selectivity for methanol. Optimization through engineering of phases and facets in such materials is often difficult

This thesis compares portrayals of Syrian and Ukrainian refugees in Swedish main stream media in 2015 and 2022, through a mixed methods approach employing frame analysis and Critical Discourse Analysis. By examining how these two groups are represented, the study reveals quantitative and qualitative patterns of differential portrayals demonstrating a moral exclusion of Syrian refugees. Viewed thro

With the advent of 5G technology, there is a growing need for advanced antennas that can support multifunctional apertures efficiently and with minimal interference, especially at millimeter-wave (mmWave) frequencies. The thesis addresses this challenge by designing, simulating, and evaluating a cloaked dipole antenna designed for 5G applications. The main concept of this work is a cloaking mechan

The aim of this study was to examine the effects of episodic future thinking (EFT) on delayed gratification using a perceptual reward paradigm. A total of 43 participants, aged 18 to 56, were recruited and asked to imagine scenarios under two conditions (EFT and control). The influence of these scenarios on the ability to delay gratification were examined in an intertemporal choice task, where pho

In my thesis I have researched civil society organisations’ (CSOs) participation in climate change policies in Cambodia. CSO participation in climate change policies is an under-researched topic globally, but especially in Southeast Asia. Empirical data was gathered through interviews with CSO representatives in organizations who are engaged in climate change mitigation and adaptation (CCMA). I ha
