The number of devices connected to the Internet is rapidly increasing. Especially the number of Internet of Things devices. These devices contain software which, like any other software, needs to be updated. With the great amount of devices to update, this calls for a manageable updating solution which does not depend on user interaction. In this thesis we present a solution to dynamically update
The aim of this study was to optimize a function starch-ethyl cellulose film for targeting the therapeutically active substance to the colon in the disease state for patients suffering from inflammatory bowel diseases. This study includes: • The preparation of the polymeric films and the investigation of the characterization (for example mechanical properties, water uptake, dry mass loss, and mic
Sweden has seen an increased number of homeless EU citizens over the last years. There is no consensus among Swedish municipalities on how to handle the issue of housing for vulnerable EU citizens. The purpose of this thesis is to examine the right to housing and why vulnerable EU citizens cannot access the right. The issue is studied on three levels – human rights law, EU law and domestic Swedish
This master thesis was a project in cooperation with Höganäs AB. The aim was to increase the apparent density (AD) of two biomass chars, by three different agglomeration methods. The reason for the investigation is that biomass char could be used as a reducing agent in the sponge iron process at Höganäs AB. The goal was to exchange anthracite in the reduction mixture to agglomerated biomass char.
This study examines the impact of sky-bridges, as an egress component, on total evacuation of a high-rise building by using an evacuation model named Pathfinder. Five scenarios, with different combination of aspects such as height of the building, number of sky-bridges (and the subsequent inter-distance between them), and people allocation have been simulated. The comparison between the results fr
Theoretically the relation between returns and idiosyncratic volatility should be non-existent or positive. Many empirical studies confirm this but Ang, Hodrick, Xing and Zhang (2006) contest the conventional view and find a negative relationship for a sample of U.S. firms. I contribute to the field by investigating the relation for a sample of U.S. mutual funds. The sample consist of a total of 1
Through economic openness, increased capital mobility and the resulting competition to innovate, the globalisation of capitalism ought to increase the wealth and living standards of all involved. However, in order for all to be involved, they must be of value to that economy. That the world lives largely in poverty means that the more the economy incorporates cheap labour, the lower the returns to
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
The following thesis investigates the extent to which economic development influences the initiation and consolidation of democracy in Asia. Based on modernization theory and its critiques, the study conducts a quantitative panel data analysis covering 46 Asian countries from 1970 - 2019. Modernization theory suggests that rising income levels, urbanization, education, and social development foste
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
