Accurate modeling of wireless channels in urban environments is crucial for the design and evaluation of communication systems. Geometry-Based Stochastic Channel Models (GSCMs) provide a balance between physical retings—an oversimplification that can reduce model fidelity.alism and computational efficiency by simulating Multi-Path Components (MPCs) through simplified ray tracing and stochastic sca

Urban environments have historically been viewed as exclusively human spaces, a notion-challenged by animal and more-than-human geography, which highlights the active roles of-nonhuman animals in shaping life. This research investigates the complex human-nonhuman-animal nexus in urban South Korea by exploring the experiences of street cat caretakers.Their care practices disrupt conventional spatia

Hur många anställda behövs för att kunna balansera kundflödet och samtidigt optimera kostnaderna av medarbetarna? Är det möjligt att beräkna stationära sannolikheter utifrån ett ankomst- och avgångsflöde, som kan användas för att optimera kö-modellen? Om du är chef på ICA, ägaren av en butik, eller en kund som har stått i kö för länge, så har du kanske ställt dig dessa frågor. Det finns olika svaThe main goal of this investigation is to determine the optimal number of cashiers to be employed in a first-in-first-out (FIFO) queuing system, based on the number of customer arrivals, the average revenue generated per customer, and the rate at which each customer abandons the queue, referred to as the reneging rate. This is done by using continuous-time homogeneous Markov Chains to model the ar

This thesis aims to study how voluntarily childfree women express identity in a Swedish society defined by pronatalist norms. Previous research has portrayed childfree individuals as marginalized, stigmatized, and even as an invisible group in Western society. The purpose of this study is to explore evolving narratives by analysing voluntarily childfree women's expression and construction of i

This thesis examines how income affects household consumption in Sweden between 1999 and 2009. Using data from SCB, the study explores how people with different income levels spend their money on various goods and services. The analysis is based on Engel’s law, which suggests that as income increases, the share of spending on basic needs like food goes down, while spending on non-essential or luxu

Minskade koldioxidutsläpp från energisektorn är nödvändigt om Sverige ska kunna nå klimatmålet inga net- toutsläpp av växthusgaser senast 2045. Biobaserad kraftvärme som drivs på restprodukter från skogsindustrin har möjligheten att bidra till minskade utsläpp men bränslena måste vara miljömässigt hållbara. Detta arbete undersöker potentialen för ett ökat uttag av grot, grenar och toppar, från sveReducing carbon dioxide emissions from the energy sector is essential if Sweden is to achieve its climate target of net-zero greenhouse gas emissions by 2045. Bio-based combined heat and power (CHP), fueled by residual products from the forest industry, has the potential to contribute to reduced emissions but only with enough fuel that’s environmentally sustainable. This study investigates the pot

I Sverige pågår en elektrifiering av samhället, där transporter, industrier och hushåll i allt större utsträckning försöker övergå till el som energibärare. Detta är en central del i att nå våra klimatmål, men ställer samtidigt höga krav på elsystemets kapacitet. För att kunna planera för ett robust och hållbart elnät krävs en förståelse för hur el används idag. I denna rapport ligger fokus på attThis report aims to develop general synthetic load profiles representing electricity consumption in Swe- dish single-family homes. Based on historical hourly consumption data from Lomma and Helsingborg, provided by RISE, three models – SARIMAX, GRU, and Prophet – were trained and evaluated. To enable comparison and future scalability, the data was normalized by each user’s annual consumption. Amon

This thesis examines how AI-generated works fit within the European Union’s copyright framework and explores alternative legal mechanisms for their protection. With the emergence of generative AI technologies capable of creating content independently, traditional copyright concepts, particularly authorship and originality are being challenged. The thesis begins by outlining the technological basi

This thesis explores the heterologous expression of six fungal enzymes with potential polyurethane (PUR) degrading activity in two strains of the filamentous fungus Aspergillus oryzae: the standard Ory6 and a knock-out variant with disrupted transcription factors to potentially reduce native protease activity. Each enzyme was expressed in three gene formats: a native version (including any introns

The observed imbalance of matter and antimatter in the universe cannot be fully explained by the Standard Model of particle physics. One proposed mechanism to account for this discrepancy is the violation of baryon number B, a process that has yet to be experimentally observed. The HIBEAM/NNBAR project, a proposed two-stage experiment at the European Spallation Source, aims to find evidence of bar

In an increasingly competitive job market, employer branding provides a tool for attracting and retaining talent. Through a case study based on a single company, this study aims to gain in-depth insights into how employer branding is enacted across different stages. To guide our study, we address the following research questions: 1) How is employer branding performed across different stages? 2)

Vad vet vi om exoplaneter? Studien av planeter har fascinerat mänskligheten sedan för de gamla grekerna, där deras rörelse över himlen representerade allt från gudar till ändringen av säsonger. Vår förståelse för de andra världar i vårt sol system, från gas jätten Jupiter, till de steniga ytan av Mars, har bara förbättrats med tiden. Detta är mest noterbart i det senaste århundrade, med flertal sSince the first discovery of exoplanets, they have been one of the main interests in contemporary astrophysics, with over 5000 confirmed today. One of the current goals is linking the chemical composition of their atmospheres to their formation by modelling the expected abundances for different formation conditions and comparing them to observations. These models require that the parameters of the

The rapid expansion of intermittent renewable energy sources has introduced substantial challenges to both the stability of the electrical grid and the economic viability of incumbent wind farms. In light of recent regulatory amendments within the energy market, stakeholders are compelled to adjust their operational strategies. Concurrently, the expansion of wind power has exacerbated price cannib

This paper examines if electrification reduces the ecological footprint. By testing the relationship for 68 countries between 2000 and 2021, the hypothesis is not supported. The estimated results indicate that while electrification is associated with lower carbon emissions, it is linked with an increase in land use, regardless of the energy source used for electricity generation, introducing an en

Denna rapport redogör över utvecklingsprocessen för ett silikonfritt, läckagetätt lock för matlådan IKEA 365+, för att undvika användandet av en silikonpackning som produkten gör idag. Drivkraften bakom projektet är att silikon är ett mycket energikrävande material att producera, samt är inte i stor skala återvinningsbart idag. Rapporten använder sig av en traditionell produktutvecklingsprocess saThis report elaborates on the development process of a silicone free, leakproof seal for the lid of the IKEA 365+ food storage platform, to alleviate the need for a silicone gasket that is used for the product today. Silicone is undesirable due to the energy intensive production and because it is not recyclable at large scale. The report uses a traditional product development process along with si
