No full textCustody disputes during divorce : focusing on the child's best interests in mutual agreement
No full textUppsatsen behandlar vårdnadstvister vid äktenskapsskillnad med särskilt fokus på principen om barnets bästa vid samförståndslösningar. Syftet är att klarlägga domstolens möjligheter att tillgodose barnets bästa även när föräldrarna är överens och barnets bästa inte tillgodoses, samt att undersöka under vilka omständigheter vårdnadsfrågor kan tas upp ex officio. Analysen utgår från svensk civilrätt och processrätt, med tyngdpunkt på föräldrabalkens (FB) 6 kapitel, äktenskapsbalkens (ÄktB) 5 kapitel, relevanta bestämmelser i rättegångsbalken (RB) samt barnkonventionen (BK). Arbetet bygger på en rättsdogmatisk metod kompletterad med rättsfallsanalys och rättspolitiska reflektioner. Resultatet visar att barnets bästa är en överordnad princip som kan motivera att domstolen frångår föräldrarnas överenskommelser i vissa fall, särskilt när det finns risk för att barnet far illa. Uppsatsen identifierar även områden där lagstiftningen kan förtydligas för att stärka rättssäkerheten och barnets rättigheter i vårdnadsprocesser under äktenskapsskillnad.The thesis addresses custody disputes in divorce proceedings, with a particular focus on the principle of the best interests of the child in mutual agreements. The purpose is to clarify the court’s ability to safeguard the best interests of the child even when the parents are in agreement but the child’s interests are not adequately protected, as well as to examine under what circumstances custody matters may be addressed ex officio. The analysis is based on Swedish civil and procedural law, with particular emphasis on Chapter 6 of the Swedish Parental Code (föräldrabalken), Chapter 5 of the Swedish Marriage Code (äktenskapsbalken), relevant provisions of the Swedish Code of Judicial Procedure (rättegångsbalken), and the United Nations Convention on the Rights of the Child. The study applies a legal dogmatic method, complemented by case law analysis and legal policy considerations. The results show that the best interests of the child constitute an overriding principle that may justify the court departing from parental agreements in certain situations, particularly where there is a risk of harm to the child. The thesis also identifies areas where legislation could be clarified to strengthen legal certainty and the rights of the child in custody proceedings during divorce
Feasibility Study and Development of mm-Wave Radar Technology for Autonomous Door Control Systems in Passenger Trains
No full textThe train industry in Sweden currently relies on cameras, infrared sensors, and manual humancontrol systems to operate train doors. During the winter months, these systems face significant challenges. Train conductors often need to manually clear fog, ice, snow, or rain from cameras to ensure proper functionality, or physically stand on the platform to verify that all passengers have boarded or alighted. These procedures are not only inconvenient but also lead to inefficiencies and increased operational burdens and risks in harsh weather conditions. This thesis aims to evaluate the feasibility of implementing an automated train door control systemusing millimeter-wave (mmWave) technology. The primary objective is to enhance operational efficiency and reliability by reducing reliance on manual intervention, thereby improving system performance under adverse environmental conditions. This thesis also investigates how Texas Instruments’ IWRL6432AOP and IWR6843 evaluation boards can be utilized to develop a fully autonomous door control system capable of accurately tracking passenger presence. Moreover ,this thesis also investigates how mmWave radar can maintain accurate object detection performance in rainy conditions, including an analysis of rain-induced signal attenuation and its impact on detection reliability. Apart from that, this thesis also explores aspects of thermal management, proposing a range of methods to reduce the operational temperature of the radar hardware. These strategies aim to improve long-term stability and extend the device’s operational lifespan, especially under continuous use in real-world environments. The experimental results indicate a promising potential for mmWave radar technology in autonomous train door control systems. The indoor simulation tests reveal that the system operates effectively: it keeps the door closed when a person merely walks by or stands still in front of it for up to three seconds. Conversely, if an individual approaches the door and remains within three meters, the door opens, demonstrating the system’s capability of discerning active intent to enter. Millimeter-wave technology presents a significant innovation opportunity for door control systems in the train industry, potentially enhancing passenger safety and train conductors don’t need to brush the camera manually or stand outside the cabin to check passengers. However, several key aspects require attention to maximize system performance. This includes fine-tuning the tracking algorithm layers to improve detection accuracy and responsiveness; continuously optimizing the tracker’s performance to ensure reliability across various operational scenarios; effectively managing antenna power; and implementing robust thermal management solutions to maintain the system’s operational integrity. Additionally, developing strategies to address signal degradation under adverse weather conditions is also critical. In conclusion, the mmWave radar technology shows considerable promise for autonomous train door control systems and can be successfully implemented on the autonomous train door control system

No full textConceptual system design for a medical device
No full textThis thesis aims to develop a conceptual system configuration for supporting a medical device intended for follow-up diagnostic screening. The background of the study is rooted in the need to improve ergonomics, precision and efficiency in the handling of diagnostic equipment within clinical environments. Key product requirements were identified through literature studies, workshops and interviews, forming the foundation for concept development. The methodology was based on an iterative product development process. CAD-modeling and finite element method (FEM) analysis were applied to evaluate the structural integrity and functionality of the design. The result was a conceptual automated system configuration characterized by user-friendliness and an aesthetically pleasing appearance. The concept consisted of an arm made of carbon fiber, integrated into a bed, with both horizontal and vertical movement, as well as tilting of the medical device. Due to time constraints, the study did not include the production or testing of a physical prototype. The conclusion indicates that the proposed concept meets essential functional and technical requirements, but further work is needed for testing and refinement before it can be developed into a final product
Är ekonomiundervisning i samhällskunskap mångfacetterad eller marinerad i nyliberalism? : En ideologikritisk idéanalys av lärarutsagor inom ekonomiundervisning i samhällskunskapsämnet på högstadiet och gymnasiet
No full textDenna studie undersöker hur ideologiska strukturer uttrycks och reproduceras i samhällskunskapslärares utsagor i undervisning om ekonomi på högstadiet och gymnasiet. Med utgångspunkt i kritisk pedagogik och en kvalitativ idéanalys kombinerad med ideologikritik analyseras fem semistrukturerade intervjuer med lärare för att identifiera hur värden, föreställningar och föreskrifter påverkar undervisningens innehåll och syfte. Särskilt vikt läggs vid begreppen kulturell hegemoni, reproduktion och läraren som transformativ intellektuell, samt kritiskt omdöme och subjektivitet. Utifrån lärares utsagor visar analysen att ekonomiundervisningen är präglad av marknadsorienterade och teknokratiska diskurser där begrepp som marknad, tillväxt och konkurrens framställs som naturliga och värdeneutrala. Samtidigt förekommer inslag av kritisk reflektion och motstånd där lärare försöker skapa utrymme för alternativa perspektiv och elevens egen meningsskapande. Studien bidrar med kunskap om hur ideologi tar sig uttryck i lärares språkbruk och didaktiska val, samt hur detta påverkar elevernas möjligheter att utveckla ett kritiskt förhållningssätt till samhällsekonomi. I relation till skolans demokratiska uppdrag aktualiserar studien behovet av en mer medveten och mångsidig ekonomiundervisning som utmanar hegemoniska perspektiv och stärker elevers subjektivitet
Reuse of Hollow Core Slabs (HD-F Floor) : Prerequisites, Challenges, and Climate Benefits
No full textThis thesis investigates the prerequisites for reusing prestressed hollow core slabs in the new construction of office buildings, focusing on the ongoing “Upside Stories” development project in Uppsala, Sweden. The aim of the study is to examine the technical and environmental consequences of reusing these types of slabs. Conducted in collaboration with Vectura Fastigheter and STUNS, the study combines a literature review, qualitative interviews with industry professionals, and a life cycle assessment (LCA) to address three main research questions: (1) the technical and practical feasibility of reuse, (2) challenges related to design, logistics, and adaptation, and (3) environmental impact compared to new elements. The findings suggest that reuse is technically feasible if sufficient documentation is available, structural components are dismantled with care, and adaptation to new projects is possible. Key obstacles include the lack of standardized dismantling routines, costs for processing and storage, and limited coordination across stakeholders. The LCA results indicate that climate impact can be reduced by up to 65% compared to newly produced slabs, mainly due to the avoidance of resource-intensive production. The study emphasizes the importance of early planning and cross-sector collaboration to enable large-scale structural reuse. These results support a transition toward circular building practices aligned with Sweden’s climate goals and the UN Sustainable Development Goals
The Mental Urbanisation of the North : Storyworlds and Scandinavian Cities, c. 1000–1250
No full textThe thesis sets out from the assumption that cities are constructed materially as well as mentally. The construction of cities in the minds of people is referred to as ‘mental urbanisation’. The aim of the thesis is to demonstrate how the early medieval urbanisation of Scandinavia can be understood as part of a mental urbanisation of the north. Mental urbanisation is studied through a thematic analysis of narratives in sources such as Adam of Bremen’s Gesta Hammaburgensis ecclesiae pontificum, Saxo Grammaticus’ Gesta Danorum and Snorri Sturluson’s Heimskringla. The main research question guiding the analysis is: how were Scandinavia’s earliest cities constructed in medieval narratives from the period c. 1000–1250? The themes structuring the analysis are: words, time, space, and order. The chapter ‘cities and words’ identifies the urban terminology used in the texts and shows how urban words could be used in the literary construction of cities. However, it is made clear that medieval writers used urban words to describe towns, not to define them. The chapter ‘cities and time’ discusses urban origin stories and shows how medieval writers constructed places such as (Gamla) Uppsala and Lejre as ancient cities as part of their ambitions to integrate Scandinavian history with learned discourses of antiquity and salvation history. The chapter ‘cities and space’ analyses how cities were constructed in relation to medieval ideas of centre and periphery. Cities such as Trondheim and Birka were narrated as centres of conversion, Roskilde and Kungahälla were important in crusading contexts, and even Jomsborg was ascribed a role in salvation history. The chapter ‘cities and order’ explores how urban space was sacralised and how cities were narrated as manifestations of divine and royal order. In the narratives, rulers connect themselves with specific cities by founding or promoting them. That cities are turned into the focal points of medieval storyworlds demonstrates their significance for medieval people. Consequently, the thesis argues that medieval urbanisation cannot be fully understood without taking into account the mental dimensions of cities, which have been largely overlooked in previous research

No full textCognition before and after psychosis onset : A naturalistic study of change heterogeneity, and prognosis
No full textAims Cognitive dysfunction is a core feature of psychotic disorders. The degree of impairment varies greatly between individuals, which may reflect different levels of decline from pre-morbid functioning. Diverse trajectories of cognitive change prior to or during development of psychosis have been hypothesized to reflect distinct underlying pathological processes. Our primary aim was to model cognitive change over time in a sample of individuals with first-episode psychosis (FEP) and controls. The secondary aim was to explore associations between cognitive change, clinical outcomes and select biological markers. Methods Our sample consisted of 72 individuals with FEP and 53 controls. School grades from nationwide population registers were used as a proxy for pre-morbid cognitive ability. All participants underwent formal cognitive testing at psychosis onset, with a subset returning for testing at 1,5 year follow up. Cognitive change was modelled using linear mixed-effects models, and resulting change scores were correlated to polygenic risk scores, cerebrospinal fluid levels of complement protein C4A and clinical outcomes. Results Groups did not differ in school performance prior to psychosis. Psychosis onset was associated with marked cognitive decline in FEP individuals, who subsequently performed significantly worse than controls. However, cognitive change over time varied widely between FEP individuals. Degree of cognitive change was not associated with the selected biological variables but did predict worse clinical outcomes. Conclusions Individual cognitive trajectories may be a clinically relevant topic for further study, and larger studies are needed to further explore their potential role in stratified models of care
