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
Denna uppsats undersöker hur mödrar som arbetstagare, omsorg och jämställdhet konstrueras i EU:s politik för balans mellan arbete och privatliv. Syftet är att bidra till en djupare förståelse för hur institutionella visioner om jämställdhet formas och vad de inkluderar respektive utesluter. Analysen fokuserar på två centrala policydokument: Arbetslivsbalansdirektiv från 2019 och Kommissionens initThis thesis explores how mothers as workers, care, and gender equality are constructed in EU work-life balance policy. The aim is to contribute to a deeper understanding of how institutional visions of equality are constructed and what they include or exclude. The analysis focuses on two central policy documents: the 2019 Work-Life Balance Directive and the 2017 Commission initiative on work-life
To promote sustainable manufacturing and lower industrial emissions, GE HealthCare is constantly assessing new approaches to improve their production processes. As a global manufacturer of contrast media, their potential for positive societal impact is significant. In addition to sustainability, a pharmaceutical production process is required to deliver products of high purity. This means that the

Methodology: Panel data regression with fixed and random effects models, analyzing stock returns on announcement dates. Control variables include buyback value, market capitalization, and leverage ratio. Theoretical perspec
This study discusses the conceptualization of punishment, human rights, and the justification of applied measures in international counterterrorism strategies. Through Deductive Qualitative Analysis (DQA) a mixed theory of punishment, discussed by philosophers such as John Rawls, H. L. A. Hart, and Matthew Altman, is applied to UN and EU counterterrorism strategies to analyze the normative justifi
Despite the removal of formal barriers and the idea of equal access to education, first-generation university students remain underrepresented in the Danish higher education system. Drawing on Bourdieu’s ideas of cultural and social capital, habitus and cleft habitus, Yosso’s idea of community cultural wealth and Tinto’s framework student retention, this thesis explores how they navigate the envir
I takt med urbaniseringen sker omfattande exploatering där stadsdelar byggs på tidigare åkermark. Markavvattningsföretag som finns kvar från de exploaterade åkermarkerna kopplas ofta in i de dagvattenanläggningar som implementeras i samband med exploateringen. Då dimensioneringsskillnader finns mellan markavvattningsföretagen och dagvattensystemen kan det uppstå översvämningar där de möts, särskilUrban development is increasing and occurring on former agricultural land. There, existing agricultural drainage systems are often integrated into newly constructed stormwater networks. However, differences in design capacities between these systems can lead to flooding at their interface, particularly during the winter. Climate change is expected to increase stormwater flow volumes, emphasizing t
How do young Chinese women use tattooing to navigate the existential challenges of modernity? Understanding these embodied negotiations requires examining tattooing's role as an embodied practice for meaning-making and identity formation. Focusing on the tensions between traditional Chinese values and modern individualism, such corporeal strategies emerge as responses to what Beck termed "
Hur kan naturliga dagvattensystem förhindra översvämningar i våra städer? Kraftigare skyfall och fler hårdgjorda ytor ökar risken för översvämningar i städer. I detta arbete utvecklades en metod för att undersöka bästa möjliga placering av blågröna lösningar för att avlasta vattenledningarna i området. Denna metod tillämpades senare på ett område i Lund där olika lösningar simulerades och effektiClimate change and increasing urbanization pose significant challenges to our urban environment. Urbanization leads to more impermeable surfaces, which, in combination with more rainfall, put communities at risk of flooding due to combined sewer overflows or overloaded drainage systems. To combat urban flooding, natural systems, also called blue-green solutions, can be implemented to mimic the nat
Hur vi utvecklar våra städer innebär viktiga och stundtals svåra beslut i samhällsbyggnadsprocessen. 3D-stadsmodeller är virtuella 3D-stadsmiljöer som kan bidra med insikter i dessa beslutsprocesser. I Sverige finns planer på att skapa en 3D-baskarta för kommuner. Den ska fungera som en 3D stadsmodell och erbjuda grundläggande information om stadsmiljöer. Den kan hjälpa intressenter, till exempel Urban vegetation and 3D city models are increasingly used strategically in urban development. However, representation of urban vegetation information in 3D city models is often lacking. Currently in Sweden, how urban vegetation should be represented in a future municipal 3D base map is discussed. Focusing on the integration of 3CIM, the Swedish extension of the semantic 3D city model CityGML, and
