Egypt’s area is approximately 1.002 million km². However, the population and economic activity are concentrated along the banks of the Nile, where the urbanization rate is approximately 7.8%, while the rest of the land is considered desert. This population and spatial density has prompted both the public and private sectors to consider and seek solutions represented by building new urban communiti

This study explores how business angels in southern Sweden use social connections and trust to find and assess potential investments. Business angels often rely on their network for finding investment opportunities, and the process can vary from one cultural context to another. Most existing research on the business angels’ investment process lacks a focus on the relational and informal mechanisms

This study’s problem formulation is based on the Swedish National Heritage Board’s report School and Cultural Heritage (2020), which calls for continued discussions about cultural heritage institutions as a pedagogical resource for schools. The purpose of this study is therefore to contribute knowledge about what relevance collaboration with museums can have for primary schools, and to map the fac

This thesis explores the patterns of shared e-scooter usage in the cities of Oslo and Stockholm, with a focus on understanding how these trips relate to public transport services. While e-scooter usage has soared during the last decade, policy makers, urban and transportation planners attempt to understand this new phenomenon and its effect to public transport.

This study investigates the intersection of climate change and social work in Sri Lanka. Incorporating theories of social and environmental justice, the focus lies on understanding how climate change exacerbates social injustices and reshapes professional practices. Drawing on qualitative data from seven semi-structured interviews, as well as participant observations in climate-affected communitie

This thesis explores how foreign reporters make sense of occupational risk-taking in war through the perspective of Stephen Lyng’s (1990) edgework theory. Thereby, the study builds on semi-structured, in-depth interviews with German journalists who have reported from the ongoing war against Ukraine following Russia’s full-scale invasion in February 2022. Although prior research has looked at the r

Climate variability poses an increasing threat to freshwater ecosystems. Particularly in temperate regions where the everchanging precipitation and temperature patterns can alter lake hydrology. The study investigates long-term variation in lake surface area in response to climate drivers across four lakes in southern Sweden, from 2000 to 2024. This was done using satellitebased remote sensing and

Sammanfattning Asfalt är ett av de mest använda byggmaterialen för vägar och påverkas kontinuerligt av klimatrelaterade faktorer som luft, vatten och temperaturväxlingar. Dessa miljöpåverkningar kan leda till nedbrytning av materialets mekaniska egenskaper och därmed försämrad livslängd och funktion. Syftet med detta examensarbete är att undersöka hur asfalt påverkas av tre miljöfaktorer: luft (Roads and asphalt pavements are continuously exposed to weather conditions, such as rain, air, and frost, which affect their durability and performance over time. This thesis investigates how asphalt is influenced by three environmental factors: air, water, and freeze–thaw cycles. Laboratory tests were conducted over a three-week period to examine how stability, deformation, and stiffness change

Tänk dig att du vill lära en dator att känna igen sjukdomar från medicinska bilder, men bara har tillgång till ett fåtal patienter med dessa sjukdomar. Eller att du vill utveckla AI för specialiserade industriapplikationer där datan är dyr och svår att samla in. Vad gör du då? Det är det här vårt examensarbete handlar om: att använda avancerade AI-modeller, så kallade diffusion-modeller, för att gDiffusion models have emerged as powerful generative modeling frameworks, excelling at producing state-of-the-art high-quality, diverse data samples across various domains. Although slightly suffering from slow sampling speed compared to other predominant approaches, various methods such as implicit and latent methods have addressed this issue. In many machine learning algorithms, including diffu

Conventional agriculture, dominated by annual crops, has revolutionised food production but also introduced significant environmental and social challenges. Perennial crops offer a promising alternative, with potential benefits for ecosystem services, agricultural sustainability, and food security. Although the environmental benefits of perennial crops, such as the intermediate wheat grass Kernza

Med utgångspunkt i att misslyckanden sällan studeras, trots att de är vanligare än framgång, syftar denna studie till att bidra med ökad förståelse för hur mobila shoppingapplikationer misslyckas med att bibehålla rekryterade användare genom att analysera de praktiker och bakomliggande faktorer som formar och påverkar deras användning och avbrott. Studien positioneras inom modeshopping och genom e

This study examines the value creation in private equity through looking at the changes of a few chosen metrics, comparing the years before and after acquisitions. Building on previous research into the operational impact of leveraged buyouts in Sweden (Bergström, Grubb & Jonsson), 2009; Nordström 2015) this thesis examines the long-run performance of firms targeted by private equity (PE). Foc

Recently, the media has brought attention to the Adam case, a young boy who was taken into compulsory care by social services in Helsingborg amid false allegations from his mother and other parties. This study aims to analyze how the media frames social services, in this case, and how different parts are given voice in the media coverage. A qualitative content analysis was performed on news articl

Hydrogen plays a pivotal role in the global energy transition, offering a clean and versatile energy carrier for a sustainable future. However, ensuring its safe use in industrial facilities requires reli- able prediction of dispersion from Venting Units (VUs). Traditional computational fluid dynamics (CFD) simulations provide high-fidelity results but are too slow for fast safety assessment and i

Mycket har hänt på 100 år, våra levnadsförhållanden har förändrats, städerna har utvecklats, men på landsbygden har tiden stått still. Förr utgjorde bondgården en central del i böndernas liv men i takt med avvecklingen av lantbruken står många gårdar tomma och har tappat sin funktion. Under den rådande bostadsbristen väljer man ofta att bygga nytt istället för att utnyttja de byggnader som rA lot has happened in the last 100 years, our living conditions have changed and our cities have developed. However, in rural areas time has stood still. In the past, the farmhouse was a central part of the farmer’s life, but since the decrease of the agricultural lifestyle, many farms are empty and have lost their function. In the current housing shortage, new buildings are often built inst

Vi kan idag se en ökande urbanisering i världen, 2018 bodde 53% av jordens befolkning i städer, en siffra som väntas öka till 60% till år 2030. Samtidigt mänsklighetens utsläpp av växthusgaser gett upphov till ökade temperaturer, som i sin tur leder till förändrade nederbördsmönster, vilka manifesteras i form av bland annat extrema regn. Detta har lett till ett ökat behov av att göra städer mer håThere is an increasing urbanization taking place in the world today, in 2018, 53% of the global population lived in cities, a figure that is expected to rise to 60% by 2030. At the same time, anthropogenic emissions of greenhouse gasses give rise to increasing temperatures, which in turn lead to changed precipitation patterns, which manifest in the form of extreme rain events among other phenomena
