This thesis presents the development of a structured framework for extrusion screw design based on geometrical parameters, with the aim of improving understanding and supporting design decisions in industrial extrusion processes. The work was carried out in collaboration with Tetra Pak and focuses on the extrusion system used in injection compression molding of Tetra Top lids. An initial numerica
The EU’s Sustainability Disclosure Framework has been substantially revised. The CSRD and the ESRS have been changed under Directive (EU) 2026/470, and the Commission has proposed a reform for SFDR, which transforms the framework’s disclosure-based structure to a comprehensive categorization system based on three categories: Transition, ESG Basics, and Sustainable. This thesis examines what change
With growing complexity of developing Application-Specific Integrated Circuit (ASIC), comes a higher development time, in both designing and verifying Reg- ister Transfer Level (RTL) code. Configurability can reduce the time spent on re-designing, and instead replace with simple reconfiguration. The configurable design then typically need initial verification effort. This thesis seeks to investiga
Lipid nanoparticles (LNPs) have emerged as an efficient platform for mRNA delivery, in which ionisable lipids play a central role in intracellular uptake and endosomal escape. In this study, the influence of different ionisable lipids on cellular uptake, endosomal damages and mRNA release kinetics was investigated to identify promising LNP compositions for effective mRNA delivery. Dose-dependent L
Stockout delay is an important component of lead time calculations in inventory control literature. This thesis presents a deep dive into the topic through a literature review, which is accompanied by a numerical study. This numerical study provides a comparison of available models along with a simulation model that looks at two different order fulfillment types: complete and partial. Based on the
Chirality is the property of an object that cannot be superimposed onto its mirror image. Chiral materials exhibit circular dichroism (CD) which can selectively populate one spin state over the other upon optical excitation, creating a spin-polarized carrier population. In chiral hybrid organic-inorganic perovskites, chirality is transferred from the organic spacer to the inorganic framework, maki
Detta examensarbete undersöker hur resenärernas upplevda trygghet påverkas när tåg passerar järnvägsplattformar i hög hastighet utan att stanna. Arbetet utgår från att järnvägen används mer intensivt än tidigare, vilket skapar fler situationer där resenärer väntar på plattformar samtidigt som andra tåg passerar. Fokus ligger på samspelet mellan plattformens fysiska miljö, tågets passage och resenäThis thesis examines how passengers’ perceived safety is affected when trains pass railway platforms at high speed without stopping. The study is based on the fact that the railway is used more intensively than before, creating more situations where passengers wait on platforms while other trains pass. The focus is on the interaction between the physical platform environment, the train passage and
Vid köp av en bostadsrätt erhåller köparen en nyttjanderätt till en lägenhet eller ett småhus. I samband med förvärvet blir köparen medlem i bostadsrättsföreningen, men förvärvar inte äganderätten till den enskilda lägenheten eller småhuset. Bostadsrättsmedlemmar är exponerade mot en dubbel finansiell risk. Utöver egna bolån bär hushållet en indirekt skuldbörda via bostadsrättsföreningens lån, varWhen purchasing a tenant-owner flat in Sweden, the buyer acquires a right of use rather than direct ownership of the property. The association collectively holds the mortgage, exposing members to a dual financial risk, their own mortgage as well as an indirect debt burden through the association's loans, reflected in monthly fees. The capital structure decision, whether debt is held collective
Bisphenol A (BPA) is an endocrine-disrupting chemical restricted by EU legislation. Consequently, the industry has transitioned to structurally similar substitutes, primarily bisphenol S (BPS) and bisphenol F (BPF). This study aimed to investigate temporal trends in population exposure to BPA, BPS and BPF among adolescents in Skåne, Sweden, between 2000 and 2022 through measured urinary concentrat
Uppsatsens ämne är det utökade skyddet för kända varumärken, syftet med uppsatsen är att beskriva och analysera förutsättningarna och gränserna för det utökade skyddet för kända varumärken inom varumärkeslagen. För att uppnå syftet har följande frågeställningar ställts: Vad innebär kravet att ett varukännetecken ska vara känt inom en betydande del av omsättningskretsen? Vad innebär att användningeThe subject of the thesis is the extended protection for reputed trademarks. The purpose of the thesis is to describe and analyze the conditions and limits for the extended protection of well-known trademarks within trademark law. To achieve this purpose, the following research questions are addressed: What does the requirement that a sign must be known within a substantial part of the relevant pu

Contemporary processes of radicalization into far-right extremism are increasingly shaped by digital, online communication environments that convey ideology through multiple communication modes, as well as aesthetic and culturally embedded forms of expression. Short-form content platforms such as TikTok enable fast production and circulation of highly engaging content that creates communicative ar
Wind damage is one of the most economically and ecologically significant natural disturbances in European forests, yet the cloud cover that follows major storms routinely blocks optical satellite acquisitions for weeks, precisely when rapid damage mapping is most valuable. Synthetic aperture radar (SAR) circumvents this limitation through all-weather imaging, but pixel-level windthrow detection fr
With increasing pressures to reduce greenhouse gas emissions, heavy-duty freight is moving to electrification, but this shift remains challenging due to high energy demand, long operating hours, strict delivery schedules, and limited tolerance for charging downtime. This thesis examines whether battery swapping combined with Battery-as-a-Service can contribute to the sustainability transition of h
Abstract Global industrial providers increasingly recognize the aftermarket as a significant source of untapped value, yet many remain challenged in the pursuit of capturing it. This research examines a global medical simulation provider where the absence of strategic segmentation between primary product flows and the distribution of spare parts has produced persistent operational misalignment. Le
Network cameras observe physical spaces but lack an inherent understanding of the scenes they see. This thesis presents a pipeline for floor and wall instance segmentation from a single uncalibrated RGB image, requiring no scene-specific prior information such as camera intrinsics, depth sensors, floor plans, or labelled floor and wall data for training. The detected instances are intended to supp
Innovation concentrations are increasingly extending beyond metropolitan cores into urban peripheries through science parks, research infrastructures, advanced manufacturing sites, and innovation districts. Yet their physical presence does not necessarily generate long-term local development capacity. Existing research has explained innovation stability largely through agglomeration, proximity, in
Moving ahead from the domination of either side of established powers like socialism, capitalism, or all the -isms, another way seems possible. As we know from history, there is a great potential and capacity that lies within civil society that finds creative ways to tackle the problems others have failed to address. The study aimed to explore the strategies that social enterprises apply to reconc
Temporary urbanism has emerged as a prominent field in urban planning and research,encompassing a wide range of terms such as meanwhile use, tactical urbanism, and DIY.Despite its growing relevance as a more sustainable and flexible approach to traditionalplanning, the concept remains ambiguous. Several scholars describe the field of temporaryurbanism as disorganized, confusing, and difficult to d
