Astrophysicists have long studied the early Universe in an attempt to explain where galaxies, and by proxy us, come from. In this thesis, the global properties of galaxies at z = 3, where star formation plays a large part , are studied when changing the stellar feedback strength and resolution in simulations. The simulation code used is based on RAMSES, using a similar setup to VINTERGATAN. Four s
One third of the produced food for human consumption is wasted throughout the sup-ply chain. Given that 45% of the Earth's habitable land is classified as agricultural land, of which 16% is used for crop production, this situation is unsustainable. Food packaging could be one of the solutions to reduce food waste. Smart packaging, which includes active and intelligent packaging, is an innovati
The extent of data usage today makes the problem of its smoothing and filtering more relevant than ever. In this thesis, we explore one of the possible approaches to this problem: smoothing splines. When trying to clean noisy data, we want the final result to be both smooth and close to the original data set, thus it is logical to simultaneously minimize both of these values, while controlling the
To probe the unsolved intersection between quantum mechanics and general relativity, this thesis theoretically investigates and attempts to further develop an experiment designed to detect quantum gravity signatures via a rare-earth-ion doped microresonator. Leading theories on quantum gravity predict deformations to the Heisenberg uncertainty principle, which would affect the dynamics of the reso
Pork makes up around 30 % of the overall meat consumption. Pig production has an impact on the environment, and its impact depends mainly on the feed used. Agriculture in general has impacts both on the climate and biodiversity. Since animal products’ consumption are increasing it is of interest to assess its environmental impact. This study aims to assess two pig feeds’ environmental impact throu
Tidigare studier har visat en minskning av artrikedom i tundraekosystem i norra Fennoskandien, vilket innebär en betydande risk för ekosystemens funktion samt för renskötselns betesmarker. I samband med klimatförändringar och ökad mänsklig aktivitet är det därför viktigt att undersöka sambandet mellan artrikedom, aktuella och historiska miljöförhållanden samt antropogen påverkan. För att adresseraPrevious studies have shown a recent decline of vegetation diversity across tundra ecosystems in Northern Fennoscandia, posing a significant risk to ecosystem functioning and reindeer grazing. In the context of climate change and increasing human activities, it is essential to evaluate the nexus between vegetation diversity, current and historical environmental conditions and human impact. Address
Carbon dioxide and argon can form hydrated clusters in water-rich environments, and their photoionization dynamics are of fundamental interest in atmospheric and astrochemistry. In this work, we combine photoelectron–photoion coincidence (PEPICO) detection with velocity map imaging (VMI) using 21.22 eV vacuum ultraviolet light from a helium discharge lamp to investigate the photoionization of ($CO
This thesis examines how environmental sustainability is emerging, adopted, and diffused across permanent motorsport circuits, an underrepresented group within sports facility research that operates under complex operational demands and increasing scrutiny from regulators, championships, and the public. Using Diffusion of Innovations and institutional theory, the study investigates the motivations
Contemporary lifestyles are increasingly characterized by prolonged sitting and reduced everyday physical activity, contributing to a range of health-related challenges. This project investigates whether residential architecture can encourage everyday movement and support health without relying on institutional or fitness-oriented solutions. The research explores how the layout of the home and
As Thailand swiftly transitions into a super-aged society, the government has implemented aged care policies rooted in neoliberal principles, emphasising "active ageing" and reliance on family support. However, this governance approach is not exclusive to the region but is recognised as a global phenomenon. Thus, this thesis explores how global neoliberal frameworks are discursively embe
This study examines and analyzes the Albanian government's decision to appoint the world's first AI minister; in its uniqueness, this decision represents a turning point in the application of artificial intelligence, interpreted and utilized as a potential means to strengthen democratic governance. The collapse of the Soviet Union and the subsequent bid for European Union membership marked
This thesis presents the development and evaluation of an embedded hardware and software platform for future Hardware-in-the-Loop (HIL) based motor testing at ASSA ABLOY Entrance Systems. The motivation for the work is to reduce the number of physical door setups required for motor testing by complementing them with a configurable HIL rig capable of simulating different door types and configuratio
This thesis presents the aerodynamic design and optimization of a three-stage low-pressure axial turbine for the RM400 turbofan engine, developed as part of the VILD project in collaboration between GKN Aerospace, Chalmers, KTH, and Lund University. The primary objective was to redesign the turbine, previously implemented with a cooled first-stage blade, into an uncooled-blade configuration capabl
The COVID-19 pandemic has been overwhelming public health-care systems around the world. With demand exceeding the availability of medical resources in several regions, hospitals have been forced to invoke triage. To ensure that this difficult task proceeds in a fair and organised manner, governments scrambled experts to draft triage guidelines under enormous time pressure. Although there are simi
This article examines why individuals in Kazakhstan continue gambling despite mounting financial losses and growing personal crises. Drawing on qualitative interviews with gamblers and gambling hall staff, it argues that gambling persistence is embedded in a moral economy of debt, in which financial obligations become intertwined with family responsibility, social expectations, and concerns about
This paper provides the preliminary findings of a newly granted two-year project investigating the adoption of disruptive technologies, by focusing on the case of additive manufacturing (AM) in the medical technology (MedTech) industry, particularly implant applications. This is done by (I) stakeholder mapping of the industry in Australia. This included members of industry, researchers, academics,
We determine which sets saturate the Szegő and Schiefermayr lower bounds on the norms of Chebyshev Polynomials. We also discuss sets that saturate our optimal Totik–Widom upper bound.
Abstract: Food availability sets the stage for incubation behaviour of a female bird and thereby indirectly determines the nest temperature, which in turn affects development and metabolism of avian embryos. Changes in development and metabolism in turn are known to influence offspring’s ability to adjust to environmental changes later in life. However, few studies have investigated the role of in
A spatially one-dimensional model of the hydrodynamics of a flotation column is based on one continuous phase, the fluid, and two disperse phases: the aggregates, that is, bubbles with attached hydrophobic valuable particles, and the solid particles that form the gangue. A common feed inlet for slurry mixture and gas is considered and the bubbles are assumed to be fully aggregated with hydrophobic
