During the production of Tetra Pak’s packaging material, holes are cut for straws and caps, generating paperboard scraps known as confetti. These scraps must be removed from the machinery to prevent build-up and potential blockages. To design efficient extraction systems, experiments and simulations are employed to understand the phenomena of confetti transport. Confetti are introduced into a simp
Submarines constitute an important part of modern navies around the world. As they are systems with a high level of complexity, the production phase of a submarine is long and prone to flaws. The earlier these flaws are detected, the less of an impact they have monetarily and on the production timeline. SAAB Kockums build submarines in sections, in which platforms are mounted with equipment o
Malaria is an infectious disease that causes death and illness in the world. The effectiveness of antimalarial drugs like chloroquine has decreased, leading to an increase in the use of organometallic complexes to treat malaria. Ferroquine is an organometallic compound that is a newly developed antimalaria drug that contains a 4-aminoquinoline unit that is coordinated to ferrocene. Eight new metal
Alla har vi någon gång behövt använda oss av GPS för att hitta vägen eller se var vi är. Då har man antagligen också upptäckt att GPS inte alltid fungerar som den ska. I detta examensarbete undersöker vi ett alternativ till GPS som använder mobilnätet för att positionera med hjälp av maskininlärning. GPS-positionering kan ha en precision på mindre än 5 meter i öppna miljöer, men som tidigare nämnGNSS is currently the most prominent method for outdoor positioning, providing an accuracy of approximately 5 metres in good conditions. However, for environments such as dense city areas or indoors, a GNSS signal reception might not be possible. An alternative method of positioning is the fingerprint-based method, which has been widely adopted for indoor positioning by sampling the signal strengt

Hur man analyserar data från encells- och spatial transkriptomik – Och vad man kan upptäcka med dess hjälp Senaste tidens tekniska utveckling har gjort det möjligt att kartlägga enskilda cellers hela transkriptom – ett mått på vilka gener som uttrycks, dvs. är aktiva. Dessutom kan avancerad bildupptagning hjälpa till med att välja ut specifika områden i vävnadsprover, där man närmare undersöker gThere is a need to closer characterise the molecular changes associated with progression from low to high mortality stage cutaneous T cell lymphoma. This has been challenging since there is high inter-patient heterogeneity in the genetics and transcriptomics of the malignant T cell populations. Modern technology has enabled single-cell resolution as well as spatially guided cell selection for whol
Hybrid zones represent crucial areas where two populations meet, mate, and produce hybrid offspring, serving as natural laboratories for studying genetic mechanisms underlying ecological traits and reproductive isolation. In Sweden, the common chiffchaff (Phylloscopus collybita) is represented by two subspecies: P. c. abietinus, which colonised northern Sweden through Finland at least 200 years ag
Bakgrund Behandlingsriktlinjer omsätter vetenskaplig evidens till praktiska regler. De är en del av sjukvårdens säkerhetsåtgärder och syftar till att göra vården säker, enhetlig, möjliggör kvalitetskontroll och minskar sjukvårdskostnader. Men det är också viktigt att inte förväxla skapande eller hantering av dokument med att hantera faktisk säkerhet. Ett strikt fokus på följsamhet till regler kan Background: Clinical practice guidelines (CPGs) translate scientific knowledge into practical rules. They aim to improve safety, ensure consistency, enable quality control, and mitigate rising healthcare costs. CPGs and other written instructions are often the target or result of safety interventions in healthcare, but it is important to avoid the trap of managing documents rather than actual safe
Ovid’s Epistulae Heroidum is unique in the way it portrays the female point of view in many ancient myths where the women’s perspective previously has not been considered. This essay focuses on four of mythological women’s letters from the Heroides; Phyllis, Dido, Deianira and Canace – all of whom commit suicide. The purpose of the essay is to discern the reason for their suicide as well as to exa
DGEM (Devlabs, Copenhagen) is a small IoT product for air quality management and can be equipped with various integrated low-cost small sensors and hardware interfaces and provides comprehensive data collection capabilities. A one-month field observation test was conducted with reference instruments at Hyltemossa research station from 6th Dec. 2023 to 10th Jan. 2024 to validate this sensor bef
This thesis describes the development process of a digital tool that can be used by locksmiths to quickly and easily find the right components for repairing and replacing electronic locking mechanisms. The tool took the form of a mobile application and was developed in collaboration with Robust Ellåsning AB in Malmö, Sweden. The report describes an iterative, human-centered design process, from da
Försörjning av varor och tjänster är en grundläggande del av ett fungerande samhälle, och stora delar av denna försörjning sker genom näringslivet och kritiska infrastrukturer. Hot i form av klimatförändringar och antagonistiska handlingar är centrala aspekter att beakta i utformningen av viktiga samhällsfunktioner för att kunna förebygga och hantera kriser. Under de senaste 10-15 åren har klimataThe supply of goods and services is a fundamental part of a functional society, and most of this supply is driven by businesses and critical infrastructures. In the shaping of vital societal functions, threats like climate change and antagonistic acts are central aspects to consider to prevent and manage potential crises. In the last 10-15 years, climate change adaption has become a tool for mitig
The climate crisis in one of the major challenges of our time. The role of trade in this context is a contested issue, both good and bad effects are plausible. One important question in this context is whether it is possible to increase the chance that trade does not have a negative impact on the environment by including environmental provisions in trade agreements. While this might be possible, i
This text aims to study the processes that took place between the Church of Sweden and the state between the years 1995-2000, when the Church of Sweden’s parishes continued to be responsible for maintaining cemeteries. Through an empirical research method a committee directive, an official report by the government, a government bill, a report from the constitutional committee and the motions that
Public diplomacy, public relations, propaganda, and strategic narratives are all under the ‘umbrella’ of soft-power and nowadays’ international relations. Strategic narratives currently represent one of the most essential tools that political actors use to increase their influence on local and foreign audiences, gain public support, and lastly achieve their foreign policy objectives.

Bergförankring kan användas för att hantera vertikal dragbelastning. När bergförankringar utsätts för dragbelastning behöver flera olika brottmoder beaktas vid dimensionering. I många projekt i Sverige leder dimensioneringen för brottmoden bergkonsbrott till långa förankringslängder. Bergkonsbrott innebär att förankringen är intakt och att berget går till brott runt förankringen i form av en kon. Rock anchors can be used to handle vertical tensile loads. When rock anchors are subjected to tensile forces there are several different failure modes that should be considered during design. In many projects designing for the failure mode called rock mass uplift leads to long anchorage lengths. Rock mass uplift failure means that the anchor stays intact and a rock cone is formed and lifted out of
Electromagnetic compatibility (EMC) is a vital part of product development, and understanding the sources and causes of the emissions can facilitate tremendously in reaching compliance requirements and reduce the work needed for troubleshooting. At Axis Communications, where this thesis has taken place, the knowledge of EMC is an important part of their work and they aspire to improve further. Thi
MRI är en icke-invasiv diagnostisk procedur som kan ge radiologer väsentlig strukturell eller funktionell information om organ. Ungefär som vid fotografering kan rörelse under förvärvet öka risken för dålig bildkvalitet. Medicinska bildbehandlingsmetoder är inte immuna mot detta problem. Bildtagningstiden varierar beroende på de fysikprinciper som utnyttjas för att ta bilden. MRI är känt för sina The framework for a fat navigator-based prospective motion correction (PMC) is already embedded on the 7 T scanner at Hvidovre hospital. This framework is dubbed iMOCO, and it tackles the motion artifact problem by registering fat navigators after each k-space readout train to some reference fat navigator taken at the start of the scan with rigid body transformation parameters. A grade of motion i
