En stigande global temperatur rubbar den naturliga hydrologiska cykeln, något som resulterar i alltmer frekventa och extrema översvämningar, men också längre perioder av torka och vattenbrist. I Kigali, Rwanda, leder klimatförändringarna till stora utmaningar i stadsutveckling och allmän säkerhet. Som svar på problemet, har Rwandas regering skapat projektet Green City Kigali, med syfte att utvecklRising global temperatures are disrupting the natural hydrological cycle, leading to both increased frequency and severity of flooding events, as well as prolonged periods of water scarcity. In Kigali, Rwanda, these shifts pose substantial challenges to urban development and public safety. In response, the Government of Rwanda is pursuing further development of Kigali through the Green City Kigali

Helios Innovations har idag problem med spridarna i sin indunstningsteknik, där flytande farligt avfall fördelas över evaporativa block. De industriella duschmunstycken som används tenderar att sätta igen och orsaka ojämn spridning av vätskan. Målet med detta examensarbete har varit att utveckla en förbättrad design av spridaren.

I takt med att klimatförändringarna blir en allt mer akut fråga ökar efterfrågan på hållbara transportlösningar, särskilt i glesbygdsområden där alternativen ofta är begränsade. Denna uppsats undersöker potentialen för små eldrivna tåg – i storlek liknande bussar och drivna antingen av batterier eller bränsleceller – för användning på icke-elektrifierade järnvägslinjer på ett kostnadseffektivtThis thesis investigates the cost efficiency of two drivetrain configurations—Battery Only and Hydrogen-Battery—for use in mini-trains operating on non-electrified rural railways. The study focuses solely on drivetrain-related components, in cluding onboard energy storage, traction systems, and associated infrastructure such as charging stations and hydrogen refueling facilities. A comprehensive l

Background: As electronic control units (ECUs) become increasingly complex and central to vehicle functionality, Original Equipment Manufacturers (OEMs) face strategic decisions on whether to develop such components in-house or outsource them. These make-or-buy decisions affect not only cost but also innovation potential, lead times, and organizational capability. Purpose: To evaluate the implica

This thesis explores how business angels’ (BA’s) human- and financial capital contribute to the early-stage development of start-ups. While previous literature has extensively discussed BAs' financial roles, the combined effect of both capital types, particularly in relation to relational trust, remains underexplored. Addressing this gap, the study applies a qualitative approach, interviewing

I en tid av lågt bostadsbyggande, med svårigheter att få byggprojekt att gå ihop ekonomiskt, finns anledning att hitta nya lösningar för att sänka produktionskostnader vid byggandet av nya bostäder. Ett alternativ som diskuterats flitigt under de senaste åren på beslutsfattande nivå är om rådande tillgänglighetskrav ger upphov till onödiga produktionskostnader, trots att de inte fyller någon funktIn a time of low housing construction, with difficulties in making construction projects financially viable, there is reason to find new solutions to lower production costs in the construction of new housing. An alternative that has been widely discussed in recent years at a decision-making level is whether current accessibility requirements give rise to unnecessary production costs, even though t

This study investigates the activist engagement strategies of U.S.-domiciled hedge funds when engaging with Japanese firms. The study forms a comparison of the engagement strategies both before Japan’s 2015 Corporate Governance Code and after. To create this comparison, two campaigns were examined. First, the U.S.-domiciled hedge fund Steel Partners and its campaign against Japanese firm Bull-Dog

The call for climate justice becomes increasingly urgent as environmental degradation and social injustices grow even more intertwined, with their compounded impacts disproportionately affecting communities in the Global South. This thesis critically examines how the European Green Deal (EGD), as a climate policy, perpetuates neo-colonial power structures under the guise of sustainability, using t

This project aims to produce cobalt nanochains and nanowire-like structures along two perpendicular directions. Using gas-based deposition techniques based on spark-ablation, nanoparticles were deposited onto substrates which were later analyzed, either visually with a Scanning Electron Microscope or magnetically using angle-dependent remanence and coercivity measurements. Instead of the biaxial m

The rapid development of generative AI systems such as large language models (LLMs) and image generators have revealed critical tensions between technological innovation and existing data protection frameworks. This thesis examines the practical challenges related to the right to erasure established in Article 17 of the GDPR, commonly known as the "right to be forgotten" in the context o

This study uses The Legend of Zelda: Breath of the Wild as a case to explore how players communicate with the game system and how identity becomes fluid within the virtual world. Adopting a qualitative research approach that combines participant observation and semi-structured interviews, the analysis draws on social systems theory to examine how players interact with technological artefacts, make

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

This master's thesis analyzes the persecution of the Yazidis through religious, structural, and psychological lenses, with the 2014 genocide by the Islamic State (ISIL) as a central focus.

Introduction The care needs of cancer patients can vary greatly across the course of their serious illness. Despite national efforts to promote supportive care – early integrated palliative care – in Sweden, systemic barriers such as ambiguous terminology and stigma complicate this development. Region Skåne Serious Illness Database (RSSID) is being developed to collect large-cohort data for condu

Time-frequency representations (TFR) typically suffer from resolution problems due to the uncertainty principle. This can lead to loss of information if signals are too close in time or frequency, or if they have significantly different energies. Methods addressing these issues and which can be used in tandem with the typical spectrogram or scalogram have been developed throughout the years. The r
