Neurala strålningsfält möjliggör fotorealistisk 3D-scenrepresentation men saknar semantisk förståelse för objektnivåsegmentering i komplexa inomhusmiljöer. Detta arbete adresserar utmaningar inom 3D-objektsegmentering i inomhusscener genom att integrera 3D Gaussian Splatting med 2D-segmenteringsmasker. Jag analyserar befintliga segmenteringsmetoder utifrån dimensionerna visuell kvalitet, noggrannhNeural radiance fields enable photorealistic 3D scene representation but lack semantic understanding for object-level segmentation in complex indoor environments. This work addresses 3D object segmentation challenges in indoor scenes by integrating 3D Gaussian Splatting with 2D segmentation masks. I analyze existing segmentation methods across visual quality, accuracy, and efficiency dimensions, t

Denna studie undersöker hur svenska kommuner förbereder sig för implementeringen av NIS2-direktivet, med särskilt fokus på övergången från NIS1 till NIS2. Genom en kvalitativ metod med semistrukturerade intervjuer analyseras organisatoriska, tekniska och strategiska anpassningar i kommunernas cybersäkerhetsarbete. Studien identifierar nyckelområden såsom ledningens ansvar, styrmodeller, samarbete

Increasing economic, social and environmental limits to the development of conventional water supply sources have shifted water resource frontiers to alternative sources, most notably desalination and wastewater reuse. In the past few years, critical scholarship has been prolific in its exploration of how desalination may redraw the hydrosocial cycle in different geographies; wastewater reuse, how

Background Exclusive breastfeeding is essential for infant health, yet its practice varies across generations and cultures. Although the health benefits of breastfeeding have been well known for decades, the utilization of infant formula feeding worldwide and in Oman, in particular, continues to rise, most likely as a result of a lack of social support and the time limit faced by working mothers.

In recent years, the study of body image shifted from focusing on the negative aspects to a more extensive view of body image. The present study seeks to validate a measure of positive body image, the Body Appreciation Scale-2 (BAS-2; Tylka & Wood-Barcalow, 2015a) in Denmark, Portugal, and Sweden. Participants (N = 1012) were adolescents and young adults aged from 12 to 19. Confirmatory factor

Background: Unplanned pregnancy is significantly associated with an increased risk of perinatal depression (antenatal and postnatal depression), emphasizing its prevalence and its potentially detrimental effects on both maternal and child health. This study aimed to investigate the association of contraception use and pregnancy intention with the risk of perinatal depression among Omani mothers. M

Women immigrating with their children are a vulnerable group often exposed to ill health and a bad environment. In Europe, women from the Middle East have a complex situation, but immigrant women from low socioeconomic status backgrounds are at highest risk, also with regard to the perinatal period in life. In Sweden, all women independent of their immigrant status are offered free high-quality pe

After a century of accelerating drainage, in the 1960s coastal wetlands became the object of unprecedented protection campaigns around the world. This paper compares the history of three successful cases of coastal wetland protection in the Mediterranean between the 1960s and 1980s: the Rhône (France), Po (Italy), and Ebro (Spain) River deltas. As most of the coast of Mediterranean Europe, these t

To effectively navigate out of the climate crisis, a new interdisciplinary approach is needed to guide and facilitate research that integrates diverse understandings of how transitions evolve in intertwined social–environmental systems. The concept of tipping points, frequently used in the natural sciences and increasingly in the social sciences, can help elucidate processes underlying major socia

Den snabba utvecklingen av artificiell intelligens (AI) skapar nya möjligheter för effektivisering inom offentlig sektor, men innebär samtidigt utmaningar kopplade till dataskydd och regelefterlevnad. Denna kandidatuppsats undersöker hur svenska regioner arbetar med att säkerställa efterlevnad av dataskyddsförordningen (GDPR) vid användning av AI. Studien bygger på en kvalitativ metod och baseras

När en kosmisk kollision mellan jorden och en annan himlakropp sker, då bildas det nya bergarter. En av dessa bergarter är den omdebatterade pseudotachylitiska breccian (PTB). Bergarten PTB består av en snabbt avkyld smälta, med inneslutna rundade fragment från omgivande litologi. PTB har kristalliserats i djupa sprickor bildade vid nedslag, de varierar i storlek från mikrometer till hundratals meWhen a cosmic collision occurs between earth and another celestial body, new rock types are formed. One of these rock types is the controversial pseudotachylitic breccia PTB. The PTB consists of a rapidly cooled melt, with enveloped rounded fragments from the surrounding lithologi. The PTB has crystallized in deep cracks formed during impact, varying in size from micrometers to hundreds of meters

Syftet med uppsatsen är att undersöka hur olika spelelement inom gamification påverkar användares engagemang och upplevelse på sociala medier. Studien använder sig av ramverket Octalysis Framework och fokuserar på tolv vanligt förekommande spelelement, såsom poängsystem, återkoppling, topplistor och tidsmanipulation. För att besvara uppsatsens forskningsfråga har en enkätundersökning genomförts me

This study investigated the influence of various native and modified starches on the quality and staling behaviour of gluten-free bread. Four starch types: native wheat starch, cross-linked tapioca starch, fractionated native potato starch (FPS), and acetylated potato starch (Amylacetate) were evaluated by incorporating them into a standardized gluten-free bread formulation as the main starch sour

Polyhydroxybutyrate-co-valerate (PHBV), a biodegradable biopolymer, holds promise as a sustainable alternative to petroleum-based plastics. In this study, PHBV was biosynthesized and extracted, followed by an extensive evaluation of various downstream purification methods focusing on surfactant-based washing protocols. Different conditions of sodium dodecyl sulphate (SDS) washing varying in temper

Denna studie undersöker hur möjliggörande tekniker i form av smart laddning, Vehicle-to-Grid (V2G) och hembatterier samtsamhällsvetenskapliga påverkansfaktorer kommer vidare bidra till denna förändring. Studien visar att formen av styrande prissignalsamt utbredningsgraden av dessa tekniker kommer ha en The objective of this study is to investigate how the power profiles of residential houses in Sweden may look like in the future. Median power profiles for typical summer and winter days were created using real customer data. The customer group analyzed consists of houses in southern Sweden, SE4, equipped with both solar electricity production (PV) and electric vehicles (EVs) with home charging st

The increase in contact resistance within battery systems remains poorly understood, despite being one of the primary contributors to battery degradation. This project aims to investigate this phenomenon by modeling the electrical interface as a contact between a pin and a busbar. The main goal is to build a DOE and machine learning framework, using Bayesian optimization to efficiently explore the
