Nanowires are promising structures for improving light absorption due to their enhanced optical properties compared to bulk materials. Silicon is a suitable semiconducting material for driving water splitting in a photoelectrochemical (PEC) cell, and is particularly attractive due to its small bandgap as well as its relative abundance and low cost. PEC cells can be enhanced by including silicon na
Purpose: To understand the key principles that enable brands to construct long-term marketing campaigns, helping communicate, maintain, and build brand identity. Design/Methodology: This study uses a case study approach by conducting content analysis of Dove’s 20-year self-esteem campaign. The analysis is supplemented by a qualitative survey of Dove’s Nordic brand management team in order to conte
This thesis critically examines the Global Digital Compact (GDC), a United Nations initiative addressing global digital disparities and fostering equitable digital governance. Using postcolonial theory and Critical Discourse Analysis (CDA), it explores the GDC’s language, power dynamics, and stakeholder representation. The study reveals that the GDC mirrors colonial dependency patterns, with the G
SAAB Dynamics produces and develops warheads and uses computer simulations to evaluate its products. Recently, SAAB has begun using neural networks to quickly obtain accurate outputs, based on simulated data, from a set of input variables with success. This thesis investigated whether interim data in the form of video frames can improve the output of the network. This thesis investigated the use o
The purpose of this thesis is to explore the motivations of young people for manifesting their consumption behavior through Instagram stories. Additionally, the purpose includes gaining an understanding of the way consumption behavior is portrayed.
Problem – Even though existing research demonstrated why higher education and entrepreneurship are being pursued, it remained unclear what drives people towards studying entrepreneurship at university. Aim – The aim of this work was to integrate the literature streams of higher education and entrepreneurship by exploring the motives and environmental factors for choosing to study entrepreneurship
An integrated lunar habitat system is proposed, combining mycelium-based biological materials, autonomous robotic construction, and modular architectural strategies to enable long-term adaptation in extreme environments. Before human arrival, robotic units construct the primary structure and initiate mycelium growth along interior surfaces. This fungal layer functions as a living sensor network, w
The QR decomposition is used to solve least squares problems, systems of equations and other important linear algebra tasks. We consider the computation of the QR decomposition for tall-skinny matrices, using the Cholesky decomposition as an intermediate step. To improve efficiency, we introduce randomised numerical linear algebra and sketching as a tool for improving computational efficiency. Num
Traditional mechanical methods for the recycling of polyethylene terephthalate (PET) fail to produce high-quality materials suitable for upcycling. Alternatives like chemical recycling face challenges due to the high energy demands, concerns, and the cost of specialized equipment. Enzymatic recycling has emerged as a promising alternative, offering a simple process under environmentally friendly c
This thesis investigates superconductivity in novel planar Josephson junctions fabricated from a hybrid Al/EuS/2DEG (InGaAs/InAs/InGaAs) heterostructure. Using electron-beam lithography, selective etching, and atomic layer deposition, Josephson junction devices, constrictions, and SQUID geometries were fabricated and a selection of the devices were characterized at millikelvin temperatures. The me
The Rohingya crisis is a profound human rights and humanitarian disaster, representing one of the most severe contemporary instances of statelessness. This condition is characterised by the systematic denial of nationality and fundamental rights, largely facilitated by Myanmar's discriminatory state-institutionalised practices and its Citizenship Law of 1982, which excludes the Rohingya from r
In the West Bank, a context of protracted displacement and institutional fragmentation, internally displaced persons remain structurally excluded from both humanitarian and national protection systems. Amid fragmented aid architecture and legal ambiguity, the Humanitarian-Development-Peace Nexus has been promoted as a framework for institutional coherence. Yet, it remains mired in a contested spac
As global supply chains become increasingly vulnerable due to geopolitical instability, rising protectionism, and sustainability pressures, the trend of reshoring has emerged as a strategic response among multinational enterprises (MNEs). This thesis explores the drivers behind the reshoring decisions of seven Swedish MNEs and examines the entry modes (EMs) through which these firms implement thei
In Sweden, climate projections indicate longer growing seasons with more frequent extreme weather events, such as droughts and heavy rainfall, posing significant challenges to existing crop systems. Simultaneously, the sector is under growing pressure to reduce its environmental footprint, especially in response to agricultural nutrients runoff contributing to the eutrophication of the Baltic Sea.
The chirality-flow formalism has proven to simplify the calculations of helicity amplitudes to the extent that the matrix element corresponding to a Feynman diagram can immediately be written down. It has also shown to speed up the computation of scattering amplitudes through numerical implementations in MadGraph5_aMC@NLO. In this thesis we investigate if automated computation of amplitudes can be
The transition to renewable energy is a critical element in global efforts to combat climate change. This study explores the decarbonization pathway for Peru’s energy sector, emphasizing renewable energy integration in the electricity generation sector. Peru's rich renewable resources—hydropower, wind, solar, geothermal and biomass—highlight its potential as a regional leader in sustainable en
In this project I investigate how architecture can give form to an institution that creates the conditions for negotiation between competing narratives. It is situated at Sillhovstomten, the contested site behind the Nationalmuseum in central Stockholm. The failed Nobel Center proposal on this site revealed that it is not an empty void awaiting to be filled, but a place where different political,
Background: Dietary management of phenylketonuria (PKU) focuses on restricting phenylalanine (Phe) intake. The European PKU guidelines and the PKU Dietary Handbook recommend a simplified PKU diet, allowing unrestricted consumption of many low-Phe foods, called free foods. While this approach may reduce the treatment burden for patients, its implementation varies. This study investigated practi
Recent advances in the field of wild avian microbiome research have significantly deepened our understanding of the eco-evolutionary dynamics of bird–microbe interactions. Consequently, the field is now approaching a pivotal moment in uncovering the ultimate factors shaping avian microbiome structure, especially in relation to birds' ecological, evolutionary, and dietary diversity. Yet, avian micr
Global manufacturing companies operate in increasingly uncertain and complex environments where changes in sourcing strategies, supplier structures and logistics networks create significant challenges for decision- making. Traditional analytical methods often struggle to capture the dynamic and interconnected nature of modern supply chains, limiting their ability to support proactive evaluation
