The Visegrad Group (V4) has often portrayed itself as the protectors and saviors of European civilization. This thesis investigates how that collective self‐image evolved across two major crises: the migration crisis (2015-2019), and Russia’s invasion of Ukraine (2022–2025). Using critical discourse analysis of prime‐ministerial speeches and press releases, and drawing on securitization theory, so

The thesis analyses four public spaces in Riga and Tallinn which have undergone architectural and therefore semiotic transformation between 2004 and 2024. The analysis is guided by a theoretical framework which combines concepts of (transnational) memory studies and urban semiotics. Together, these emphasise a distinction between the memory of transnational space, the local place, and the material

I have always been an avid reader and I have often found myself wondering how other people picture the same spaces that are described. In many cases, the built environment is crucial to build a f ictional world for a story to take place, but sometimes it plays a particularly essential part in understanding the story, its characters and events. In these books, the architecture itself is the story.

This thesis examines the temporary use and development of Botulfsplatsen, a future central public square in Lund, Sweden. Previously a node for city buses, the municipality decided to repurpose the site for interim use as a way to test and activate the square prior to its permanent reconstruction. Drawing on theories of placemaking, temporary use, and relational geography, the study addresses two

In this paper we dive deep into the interwar agricultural policys and how they became to be. The aim is a better understanding of how the state thought the future to be in a time where change happened everywhere. From 1950 to 1970 around 131 000 agricultural units disappeared, far too many to be explained by natural causes. Through an analysis of several government public investigations we come to

This report explores how the design of a contemporary railway station can contribute to the identity and functionality of a small, relatively unbuilt location like Alsike, a growing town in Knivsta municipality. The primary question centers around how a modern station, beyond its main function as a transport hub, can serve as a gathering point, integrate different functions and reduce the railway’

This thesis explores the philosophical implications of commodification, focusing on the claim made by Jason Brennan and Peter Jaworski in Markets Without Limits (2013) that ”if you can have it, you can buy it; if you can give it away, you can sell it.” Their thesis argues for the moral permissibility of commodifying any good or service that is already permissible to exchange without monetary compe

Undersökning hur elektroniska tillstånd i ytlager av TbIr2Si2 kan manipuleras med temperatur. Viktigt för utvecklingen av nya elektroniska material är möjligheten att kontrollera och justera hur elektronerna rör sig i materialet. Detta uppfylls av TbIr2Si2-kristaller. Dessa kristaller är uppbyggda av många lager av atomer bestående av de olika ämnena Terbium, Iridium och Kisel. I de översta lagrSpin-polarized two-dimensional electron states (2DES) at the silicon terminated surfaces of LnT2Si2 compounds, show promising spintronics applications due to their magnetically controllable transport properties. In this master thesis, the objective is to study TbIr2Si2 crystals, which are a member of the LnT2Si2 family, and their magnetic ordering transition. In these systems spin orbit and exchan

This project explores how tactile interaction can lower the barrier to digital sound creation by replacing conventional musical interfaces with abstract, touch-sensitive surfaces. Drawing from a personal challenges with the technical constraints of traditional and digital instruments, the work addresses how rigid systems often inhibit creative flow, especially for users without theoretical trainin

We present classical results for convex polytopes. After reviewing quaternions, we apply these algebraic tools to polyhedral graphs. In 1891, Eberhard wondered if there exists a trivalent polyhedron with an odd number of multitrivalent faces. In 1964, Motzkin was able to find a solution to the problem. He used the group formed by the 24 units in the ring of Hurwitz quaternion integers to obtain th

This work examines the application of time geography to understand children's everyday and independent mobility. Over the past few decades, children's daily lives have become increasingly institutionalized, filled with organized activities aimed at maximizing their development. Concurrently, children's independent mobility has decreased, with parents often driving them to various activ

Denna kandidatuppsats utforskar hur lagerarbetare upplever de digitala system som numera präglar deras dagliga arbete. Digitala system är fortfarande relativt nytt inom logistikbranschen, och den forskning som hittills gjorts fokuserar främst på ekonomiska aspekter och hur de kan öka produktiviteten. Denna uppsats lyfter fram arbetarens perspektiv och hur de upplever omställningen i termer av stre

This thesis investigates the focusing performance and robustness of auto-focusing Airy beams in near-field wireless communication scenarios. Through a combination of simulations using MATLAB (Matrix Laboratory, a numerical computing environment) and full-wave electromagnetic simulations in FEKO (Feldberechnung für Körper mit beliebiger Oberfläche, an electromagnetic solver developed by Altair), th

Based on six interviews with employees at cultural institutions, this study investigates how events in support of Palestine were restricted by the Copenhagen municipality in the period between November 2023 and March 2024. Following Braun and Clarke’s (2022) approach to reflexive thematic analysis, I analyse the interviews and draw on theoretical perspectives regarding anti-Palestinian racism, cri

This essay examines how the choice of theory and model affects the conclusions drawn regarding short run stabilization policy. This is done by comparing the ‘orthodox’ New Neoclassical Synthesis with the ‘heterodox’ post-Keynesian theory as well as their corresponding benchmark-models using scenario analyses. We model both a small and a large shock to autonomous investments and compare the policy

In recent years, populist support has grown while public confidence in political and economic institutions has weakened across Europe. This thesis explores the connection between these trends by asking whether populist participation in national cabinets undermines trust in domestic and supranational institutions. Using Eurobarometer surveys and election data from 25 EU member states between 2000 a

Deep learning models have significantly improved the advancement of monocular 3D face reconstruction models. However, such models often struggle to capture person-specific high-frequency details. To address this issue, this report proposes a hybrid reconstruction pipeline that enhances DECA produced 3D face models by incorporating RGB-D data captured with the consumer grade iPhone TrueDepth camera

Användning av vitamin B9 för en mer selektiv cancer behandling. Cancer är idag en av de vanligaste dödsorsakerna i världen och omfattar över 200 olika sjukdomar. Det som förenar dem är att kroppens egna celler börjar dela sig okontrollerat och sprida sig i kroppen. Om sjukdomen inte behandlas kan den leda till organsvikt och död. Trots stora framsteg inom forskningen är cancer fortfarande en storCancer remains a leading cause of death worldwide, with over 200 types characterized by uncontrolled cell growth and spread. Despite advances in understanding its molecular basis, treatment remains challenging. Chemotherapy, a common approach, lacks specificity and often harms healthy cells, leading to severe side effects. To address this, targeted therapies have emerged, aiming to deliver drugs d

Empirical evidence suggests that post-communist countries uniformly exhibit significantly more negative immigration attitudes compared to Western countries. However, many aspects of this tendency remain under-researched – including its potential underlying causes. This study hypothesises that the delayed emergence of modernisation processes in post-communist countries may be a key explanatory fact

The ability to manipulate spin states with light forms the basis of spin-based photonics. The development of semiconductors with tunable spin properties will enable devices that use spin for information storage, circular polarized light emission, etc. With the recent reports of a chirality-induced spin selectivity (CISS) effect in electrons, the question arises whether structural chirality provide
