Concrete exhibits high compressive strength but limited tensile strength, which restricts its applications where it's structurally efficient with respect to cost, manufacturability and strength. Prestressing is commonly used to counteract tensile stress by introducing compressive forces but the combination of prestressed concrete and optimization is still under development. An important aspect
The objective of this thesis is to expand on previous research by implementing a new method for order-restricted estimation of length-biased data. This paper addresses the implementation and analysis of a stochastic spatial probabilistic model for characterizing the geometric relationship between perpetrator addresses and crime scene locations. The given data are length-biased observations of a de
Romanen Den första boken handlar om ett kärlekspar, en svensk vit flicka och en ung svart jamaicansk man. Handlingen utspelas i nutid på Jamaica när flickan besöker ön då och då under 5 års tid för att skriva om ön. Paret möter svårigheter på grund av mosättningar mellan maktordningar som kön, ras/etnicitet, klass. Postkolonialismen har ett stort inflytande på både svarta jamaicaner och vita besök
Barnets bästa är en grundläggande princip i svensk familjerätt. Enligt 6 kap. 2 a § föräldrabalken (FB) ska barnets bästa vara avgörande i alla frågor om vårdnad, boende och umgänge. Den 1 januari 2025 trädde en lagändring i kraft, vilket innebar en omformulering av bestämmelsen. Lagändringen medförde att risken för att barnet far illa ges en mer framträdande plats i bedömningen av barnets bästa. The best interest of the child constitutes a fundamental principle in Swedish family law. Pursuant to Chapter 6, Section 2 a of the Swedish Children and Parental Code (FB), the best interests of the child shall be decisive in all matters concerning custody, residence, and visitation. On 1 January 2025, an amendment to the law entered into, force entailing a reformulation of the provision. The amen
This master’s thesis explores the impact from the fire investigations by the Swedish Accident Investigation Authority (SHK) on fire safety in Sweden. Through a mapping survey and a qualitative interview study, it is found that it is often difficult to identify clear connections between the investigations’ safety recommendations and real improvements to fire safety, due to long time spans and multi
This master thesis aims to improve the physical design of smart ear tags for animals. The focus was to minimize the risk of tags falling off or causing harm, while considering environmental and animal welfare aspects. The project followed the methodology of Ulrich & Eppinger’s product development process, which included stages such as planning, concept development, and testing. Data collectio
Pig iron is a key material in cast iron production where impurities and trace elements (ITEs) can significantly influence graphite morphology and the overall cast iron quality. The purpose of this study is to investigate the occurrence and variation of ITEs in pig iron to assess the quality from a compositional perspective, with emphasis on elements contributing to carbide formation. Pig iron samp
2016 was historic for Colombia since it put an official end to the fifty-two year long armed conflict. The peace was agreed when the Final Peace Agreement was signed by the two major actors, Fuerzas Armadas Revolucionarias and the Colombian Government. This research aims to investigate how female victims-survivors of the armed conflict in Colombia are influencing peacebuilding. The investigation f
The functional decline of hematopoietic stem cells (HSCs) with age is a well-documented phenomenon, associated with various health complications, including anemia, impaired immune responses, and chronic inflammation. This dysfunction can contribute to the onset of hematological disorders such as myelodysplastic syndrome (MDS), chronic myelomonocytic leukemia (CMML), and acute myeloid leukemia (AML
Enhancers are central regulators of cell-type-specific gene expression, yet direct functional mapping of active enhancer-promoter interactions in single cells remains technically challenging. DNA adenine methyltransferase (Dam)-based chromatin recording offers a strategy to mark genomic regions proximal to proteins associated with active transcription sites in vivo, including enhancer regions, and
The introduction of the Environmental Transmission Electron Microscope (ETEM) has revolutionized scientific studies by allowing in-situ studies of nano and angstrom scale samples in varying environments. In combination with the introduction of the Microelectromechanical Systems (MEMS) chip the ETEM has become a powerful tool for high resolution imaging of material interaction. However, the MEMS ch
With climate change causing more intense rainfall events and prolonged droughts, freshwa-ter resources are increasingly under pressure worldwide, including in regions such as Sweden where water scarcity was previously unexpected. While water conservation can reduce de-mand to some extent, long-term water security requires alternative and resilient water sources. Wastewater represents a reliable so
The city is a place where different activities take place side by side. The private next to the public, the sacred next to the everyday. For this, a rich variety of spaces is required - fronts and backs, insides and outsides, large and small, common and private. A spatial ecology of rooms, streets, passageways, and courtyards, relating and dependent on each other. Both general and specific. What m
Accurate thermometry is essential for experiments in cryogenic environments, particularly those using dilution refrigeration to reach milli-Kelvin temperatures. In this thesis, the calibration range of a Cernox CX1050 sensor was extended below its nominal lower limit of 1.4 K. In addition, the response of RuOx sensors at different positions within the dilution refrigerator was examined to assess t
Indoor positioning is a challenging problem due to complex environments, signal attenuation, and multi-path effects. A promising approach to this problem is channel charting on wireless networks, where high-dimensional channel state information (CSI) is mapped into a low-dimensional latent space, which preserves spatial relationships in a self-supervised manner. Channel charting can be deep learni
This thesis investigates the possibility of shortening setup times for the hardware testing rigs at BorgWarner’s Landskrona location. All the test rigs in question use the same measurement and control software, NI VeriStand. NI VeriStand is a data acquisition and control software created by National Instruments. This software needs a certain file, a system definition file,to coordinate the communi
