The purpose of this thesis is to cover the definition and basic properties of the Hausdorff measure and treat the proofs of Davies and Cordoba of the Kakeya conjecture in R^2. The conjecture states that any compact set in R^2 containing a line in every direction has Hausdorff dimension 2. Using mainly basic measure theory we construct the Hausdorff measure and develop relevant theorems, such as Ma

5-Hydroxymethylfurfural (HMF) is a versatile bio-based platform chemical that can substitute fossil-derived intermediates in polymers, solvents, and fuels, thereby contributing to a fossil-free chemical industry. While first-generation feedstocks such as high-fructose corn syrup have been widely studied, their use raises concerns about competition with food supply. In contrast, second-generation r

With the rapid evolution of semiconductor technology and the growing demand for high-performance, low-power System-on-Chip solutions, the design of efficient and scalable on-chip interconnect architectures has become a critical challenge in modern ASIC development. This thesis focuses on design space exploration of replacing multiple ARM CoreLink NIC-400 crossbar-based interconnects with a unified

This project explores how design can humanize the act of sound recording by shifting focus away from performance- and technology oriented design solutions. Through user research and an in-depth analysis of the current market, human-centered design principles were identified, highlighting the importance of intuitive controls and direct feedback in handheld audio devices. The findings highlight a gr

This paper explores identity, personhood and sickness through a postcolonial lens in regards to the literary pop-cultural zombie in the 21st century. The zombie figure is studied in regards to theories of "the other" and "othering" as well as sociological and literary theories about illness, the paper thus falls within the field of medical humanities. Questions about identity,

Power amplifiers play a crucial role in wireless communication systems. However, they can achieve high efficiency only when operating in the nonlinear region. To maintain linear output while operating in this region, several techniques have been developed, among which digital pre-distortion (DPD) is one of the most widely used. In this thesis, we designed and analyzed a digital predistortion (DPD)

This study examines the perception, implementation, and challenges of sustainable supply chain practices among small and medium-sized enterprises (SMEs) in Nigeria's retail sector. The retail industry in emerging economies like Nigeria, is dominated by SMEs, are crucial for economic growth and employment but often face significant barriers to adopting sustainability. Using a qualitative metho

There is scientific consensus today on the importance of local climate work. Many studies have investigated the mechanisms behind effective climate work and what makes some cities and large municipalities the frontrunners in driving progressive climate agendas. While this area of local climate work is well researched there is little research about how climate work looks like in small (non-rural) m

Non-typeable Haemophilus influenzae (NTHi) is a commensal with opportunistic tendencies that reside in the human nasopharynx. Since the implementation of the H. influenzae serotype b vaccine, NTHi infection has significantly increased worldwide and is of particular concern to society’s most vulnerable such as young children, elders and immunocompromised individuals. Diseases associated with NTHi a

Denna uppsats närmar sig svenskt plein-air måleri i Fontainebleau och inom konstnärskolonin Grèz-sur-Loing från slutet av 1800-talet genom längtans lins. Med utgångspunkt i temat nostalgi och apodemialgi – längtan hem och längtan att bort – undersöks landskapsmåleriet och hur det visualiserar teman om natur och modernitet. Denna tid av exil är en viktig punkt i svensk konsthistoria eftersom den haThis thesis examines late 19th-century Swedish plein-air painting in Fontainebleau and within the artists’ colony Grèz-sur-Loing through the lens of longing. Drawing on the theme of nostalgia and apodemialgia—longing for home and the longing to leave—it investigates how landscape painting visualizes themes of nature and modernity. This time of exile is an important point in Swedish art history as

Cumulate xenoliths from beach boulders in Anaga, Tenerife were analyzed through optical microscopy, scanning electron microscopy (SEM), both EDS and EBSD, and barometric modelling to study the magmatic evolution and volcanic plumbing system of the Anaga massif. Petrographic results indicate crystallization from hydrous basaltic magmas at equilibrium. This was further supported with chemical analy

Denna studie har som syfte att undersöka hur naturbaserade bygglösningar kan användas i urbana miljöer för att främja biologisk mångfald. Arbetet undersöker också vilka utmaningar och möjligheter som finns för aktörer inom Sveriges byggbransch som arbetar med implementering av dessa lösningar samt hur de upplever nuvarande styrmedel och lagstiftningar. Bakgrunden till studien bygger på den urbanis

Syftet med min uppsats är att undersöka hur typograferna upplevde övergången i tryckteknik mellan högtryck och offsettryck. Inledningsvis beskrivs skiftet till offsettryck och de konsekvenser som följde. Undersökningen utgår från respondenternas utsagor om teknikskiftet. I min kvalitativa analys har jag använt Bosse Angelöws teori om övergångsprocesser med individen i centrum, för att försöka förs

In this research, 2D hydraulic modelling is applied in the Rwandex-Magerwa catchment to investigate the flood conditions and to quantify needed detention volumes during extreme rainfall. In the calibration uncertainties concerning calibration data were discovered, the total precipitation and outlet flow volumes show large differences, the difference in time between flow and rain peaks intensities

Title: Rules, roles and risks- A study on occupational health and safety in the construction sector Author: Tova Westerlund Supervisor: Radhlinah Aulin Examiner: Anne Landin Aim & goal: The purpose of this report has been to investigate occupational health and safety risks in the construction sector, how responsibility roles relate to these risks, and the impact of Arbetsmiljöverkets regulatio

This study investigates the application of Bayesian methods in Media Mix Modeling (MMM) and compares their performance against more traditional regression models. We develop multiple MMM's to quantify the impact of media and non-media variables on a company's performance, including: (1) a Bayesian regression model incorporating prior knowledge and posterior inference, and (2) simpler regre

Den nya AI-boomen sänker kraftigt kostnaden för att bygga mjukvara, snabbar på imitationen och intensifierar konkurrensen inom Software as a Service (SaaS), vilket pressar betalningsviljan mot noll. Denna studie ställer två frågor: (1) vilka affärsmodellsinnovationer och utmaningar kännetecknar monetarisering av gratis digitala tjänster, och (2) hur kan dessa insikter tillämpas på ScanThisWine, etThe new AI-boom dramatically lowers the cost of building software, accelerates imitation, and intensifies competition in Software as a Service (SaaS), pushing willingness to pay towards zero. This study asks two questions: (1) which business model innovations and challenges characterise the monetisation of free digital services, and (2) how can these insights apply to ScanThisWine, a free e-label
