This thesis investigates the effects of monetary policy shocks, both domestically from the Swedish Riksbank and internationally from the European Central Bank, on eight macro-sensitive Swedish equity indexes over the time period 2004-2024. Employing high-frequency yield changes around policy announcements, we extract level, slope and curvature factors via principal component analysis and use these
Från det att kvantmekaniken utvecklades under den större delen av 1900-talet har en mängd nya områden introducerats inom fysikens värld. Bland dessa finner vi fasta tillståndets fysik, som beskriver hur de allra minsta partiklarna interagerar med vår värld. Framförallt vill man beskriva hur partiklar beter sig i olika material, samt reagerar på diverse externa krafter. Detta är till exempel en oerMulti-dimensional spectroscopy is a technique used by scientists to capture ultra-fast quantum effects. In particular, it uses several different frequencies to investigate nonlinear responses. Here we use this technique and apply it on a system of 2 spin-1/2 particles having some magnetic moment, and investigate the behavior of the probability density for a certain spin-state as well as the spin e

The algorithms were developed by the thes
I takt med att hållbarhet blir viktigare söker många företag inom jordbrukssektorn lösningar för att fasa ut fossila drivmedel. Utmaningen blir ännu mer komplex när ersättningen ska vara kompatibel med en existerande fordonsflotta, utan investering i nya fordon. Denna studie jämförde fyra kommersiellt tillgängliga och förnybara drivmedel med referensbränslet diesel. De undersökta drivmedlen är HVAs sustainability becomes more important in today's society, many companies in the agricultural sector are looking for new alternatives to fossil fuels. The challenge becomes even more complex when the replacement must be compatible with an existing vehicle fleet, without requiring new investments in vehicles. This report compares four commercially available and renewable fuels, using convent
This thesis investigates cost inefficiencies within the inbound logistics operations of Roam Electric, a Nairobi-based electric vehicle manufacturer. As Kenya’s electric vehicle market expands, managing logistics costs becomes increasingly critical for local firms navigating infrastructural, regulatory and operational challenges. This research adopts a holistic single-case study approach and devel
This thesis investigates the sustainability of Sweden’s reformed pension system, first introduced in 1998. The new reform addressed long-term demographic challenges, particularly population ageing. By linking pension benefits, the new system has systematically shifted financial responsibility from the state to the individual. The study assesses whether the motivation behind the reform has taken
The increase in contact resistance within battery systems remains poorly understood, despite being one of the primary contributors to battery degradation. This project aims to investigate this phenomenon by modeling the electrical interface as a contact between a pin and a busbar. The main goal is to build a DOE and machine learning framework, using Bayesian optimization to efficiently explore the
Migrän är en neurologisk sjukdom som drabbar ungefär 15 procent av världens befolkning och har stor påverkan på individens vardag. Sjukdomen karaktäriseras av attacker som ger kraftig huvudvärk, tillsammans med illamående och känslighet mot ljud och ljus. Även om det är attackerna som kännetecknar migrän, upplever många även symtom, som trötthet och ångest, mellan anfallen. Kvinnor är överrepresenMigraine is a highly debilitating neurological disorder that affects approximately 15% of the global population. It is most commonly associated with severe headaches that can leave sufferers bedridden, but its impact extends beyond the attacks themselves. The disease presents in various forms, ranging from sporadic attacks to regular ones following the female hormone cycle, and chronic migraine, w
This thesis examines the literary space of Macondo and its transformation due to external national influences in One Hundred Years of Solitude (1967) by Gabriel García Márquez. A case study is conducted of three key episodes in Macondo’s increasing contact with the state. The objective of the study is to analyze their respective spatial logics as a basis of the production and transformation of Mac

Climate change is an escalating global issue, with various parts of the world being impacted differently depending on their geographic placement, development status and financial resources. Over the last couple of decades, the intensified climate change impacts have made the climate a subject to be securitized. This happens when a securitizing actor, like a state representative, articulates the cl
October 7th 2023 a terror attack on an Israeli music festival took place. This would subsequently escalate the conflict between Israel and Palestine, with many calling it a genocide of the Palestinian people. This thesis investigates how pro-Palestinian demonstrations in Lund and Malmö following October 7th can be understood in relation to police strategies and Anne Nassauer’s theory about situati
This thesis investigates how government communication officers navigate the strategic challenges posed by homeless media—informal, unregulated digital actors that increasingly shape public discourse in Indonesia. Drawing on qualitative interviews with eleven officers across national-level agencies, the research applies the Government Communication Decision Wheel (GCDW) and the concept of instituti
This thesis explores how individuals experiencing Postural Orthostatic Tachycardia Syndrome (POTS) constitute themselves as entrepreneurial subjects within contemporary neoliberal culture. Through 6 semi-structured interviews with Swedish women suffering from POTS, this study explores the subjectivities formed at the intersection of chronic illness and neoliberal regimes of truth. Drawing on Fouca
Gestures are usual companions to the words we speak, either enhancing them or simply accompanying them. Multiple studies focus on the relationship between gestures and speech, and even how they might affect who is listening. In more recent times, the field of investigation expanded to include insights into human behaviour in virtual contexts, making the most of the headsets worn by the users to, i
Botswana’s reputation as a beacon of fiscal prudence in resource-rich economies faces new challenges. Yet recent pressures – rising debt, declining surpluses, and fiscal volatility – raise questions about the long-term sustainability of this model. This thesis examines how Botswana’s fiscal capacity has shaped its ability to manage natural resource wealth between 1990 and 2022. Drawing on a compos
Decarbonising hard-to-abate sectors such as the steel industry presents a major challenge for the European Union and its member states. These sectors must reduce emissions while maintaining global competitiveness, placing considerable pressure on both industry actors and policymakers. One proposed solution is the development of green lead markets, which aim to lower investment risks by enabling ma
