Energilösningen för Framtiden: Vattenpumplagring & Vindkraft Genom åren har användningen av fossila bränslen minskat, samtidigt som vi sett en ökning av förnybara energikällor som vindoch solkraft. Sverige står dock inför en utmaning: vindens oförutsägbara natur skapar problem för elnätets stabilitet. Denna rapport utforskar möjligheterna kring el-lagring genom vattenpumplagring kopplat till The introduction of the Renewable Energy Directive 2009, increased the renewable energy sources (RES) in the European Union (EU) and especially Sweden. Given the uncontrollable nature of weather patterns, energy generation is likely to become more volatile, thereby elevating the risk of curtailment and negative energy prices. The electricity demand in Sweden is also poised to rise sharply in the u

The creation of new words or expressions, known as neologisms, plays a crucial role in the evolution of language, reflecting societal changes, technological advancements, and cultural shifts. Their presence has become even more prominent in recent years due to the effects of globalization and the widespread influence of the English language. This thesis aims to investigate recent neologisms in Mod

Detta examensarbete behandlar effekten av slagg som ersättningsmaterial till Portlandcement och dess påverkan på hållfasthetsutvecklingen, med krav på den tidiga hållfastheten. Syftet med denna studie är att undersöka möjligheten att förbättra betong med hänsyn till dess klimatpåverkan genom att ersätta en del av Portlandcement med ett mindre miljöbelastande bindemedel. I den experimentella delenThis thesis addresses the effect of slag as a replacement material for Portland cement and its impact on strength development, with focus on early strength requirements. The aim of this study is to explore the possibility of improving concrete in terms of its environmental impact by using more eco-friendly material. In the experimental part of this work, various mixtures with different slag amount

The research "Beyond Survival: How Refugee Entrepreneurship Challenges Humanitarian Boundaries" explores the evolving dynamics within refugee camps, which transition from temporary shelters to permanent communities and where self-reliance is not just a concept but a lived reality. Through the literature review and a case study of the Syrian refugees in the Za’atari camp, this research re

Denna uppsats syftar på att analysera förändringar i svensk skogspolitik över tid med ett fokus på hur diskurser har format och formats av dessa förändringar. Sveriges landyta består av 68 procent skogsmark. Skogen är huvudsaklig för ekonomi, biologiska mångfald och arbetet mot klimatförödelse. Att förstå sig på hur lagarna som bestämmer över skogspolitiken är då viktigt på en nationell nivå för a

Homeric epics have been a continued object of interest across the ages, and it is no different today. Retellings of Greek myths with a focus on the female characters are especially popular with the modern reader. Authors Natalie Haynes and Madeline Miller are two of many who, through their contemporary novels A Thousand Ships (2019) and Circe (2018), have put the focal point on female characters.

The dissertation deals with the load-bearing capacity, in terms of stability, of a steel truss in an industrial building. It is based on previous work by Tosovic [1], in which the roof was investigated in the same type of building but the results showed that the trusses were the deficient elements. Steel trusses are a popular choice of construction for large-span buildings due to their load-beari

In this thesis, we construct the Baer sum of extensions in the sense of Yoneda and prove that it endows the Ext-classes with an Abelian group structure. Extensions are defined by means of equivalence classes of short exact sequences in Abelian categories. Now, in order to do that, we carefully lay a solid foundation for the theory of Abelian categories by starting with elementary concepts from cat

Thanks to technological advances, AI has advanced to areas previously thought to only be performed by humans. By imitating human cognitive ability, AIs are having a growing impact on medical practice, where the rapid development of data analysis tools is contributing to a significant change in healthcare. The potential for AI in healthcare is vast. However, AI can offer both ethical and human righ

To investigate the non-zero nuclear Schiff moment exhibited by PT-violating nuclei, this paper examines the prediction of shapes and excited states of Radium isotopes by applying different Skyrme-like models. The calculations were conducted by employing computational programs incorporating both the Hartree-Fock-Bogoliubov method and Hartree-Fock + BCS with an effective Skyrme force. A preliminary

Bakgrund. Industrierna utsätts för allt större press att anpassa sig till de håll- barhetsregler som införs. Detta tvingar industrierna att utmana de traditionella tillverkningsprocesser och hitta sätt att göra dem mer hållbara. I de traditionella industrierna används mycket kylvätska, som har stor inverkan på både den miljön och den sociala hållbarheten. Två produktionsmetoder uppvisar betydande Background. Industries are facing increasing pressure to adapt to sustainability regulations being put in place. This forces industries to rethink traditional manufac- turing operations and find ways to make them more sustainable. In the traditional industries there are a lot of coolants being used, these have a big impact on both the environment sustainability as well as social sustainability. Tw

This study investigates the performance dynamics of Swedish mutual funds, with a particular focus on the impact of active management, as measured by tracking error, on risk-adjusted returns (Sharpe ratio). The findings reveal a consistent negative correlation between tracking error and Sharpe ratio, indicating that higher levels of active management are associated with poorer performance relative

Title: Increasing warehouse efficiency by digitalizing warehouse processes using mobile devices – A design study in the steel industry Author: Sören Castor Supervisor: Joakim Kembro, Department of Industrial Management and Logistics, Faculty of Engineering, Lund University Problem description: Heine + Beisswenger does not or only partly document material movement in parts of their warehouse which

This thesis examines the practices and challenges of a sole management of a cultural enterprise by studying the case of Cadence Gallery and its founder Elsa, a cultural entrepreneur who solely established and manages a non-profit art gallery in Sweden. The qualitative research is based on semi-structured interviews with the entrepreneur and other individuals involved in the gallery's operation

This study aims to examine whether there is a greenium on corporate green bonds in the Nordic market and to explore the impact of industries' carbon emission level characteristics on the greenium. The study is made using a quantitative method with a deductive approach. The methodical procedure is based on a matching process, followed by a t-test and cross-section regression. The empirical find

Transitioning away from fossil fuels is prominent to stay within the 1.5-degree limit outlined in the Paris Agreement. For this to occur, the socio-technical energy system needs to become more flexible and support decentralized systems. One way to do this, as advocated by the European Union as well, is to support local energy initiatives. This paper examines how different local energy initiatives

As the problem of memory-safety continues to pose a significant threat to the software ecosystem, developers need to consider strategies to address these vul- nerabilities. For high-performing applications built on the C/C++ programming languages, solutions have to be easy to adapt without compromising too much on performance. In this thesis, high-performing 5G software is evaluated using the CHER

This study aims to problematise food assistance mechanisms in Lithuania in response to rising food insecurity, challenging the prevailing discourse surrounding food (in)security. Using interviews and document analysis within a case study methodology, the research addresses three main questions: How is food insecurity problematised in the Lithuanian state and charity discourse? How does this proble
