Cities play a crucial role in mitigating climate change, yet reducing transportation emissions remains a challenge. Achieving decarbonization in the transportation sector requires systemic transformations across society. However, there is still a limited understanding of how transitions within transportation can be achieved, and further insight is needed to guide cities in driving transformative c

With an ongoing energy crisis in Europe and an ever-evolving political climate where the environmental impacts of industries are regarded as a top priority, the topic of energy efficiency is high on everyone’s agenda. Mathematical optimization of energy consumption requires a model of the problem at hand. In this thesis linear regression is compared with the gradient boosted trees method and a neu

Sedan 1960-talet har världens befolkning ökat med nästan en miljard varje årtionde. Med denna ökande befolkning följer ökande energibehov. Fram tills år 2023 har den globala energiproduktionen dominerats av icke-förnybara energikällor som till exempel kol och olja. De kallas icke-förnybara energikällor eftersom de inte är återanvändbara och är ändliga. Utöver detta så släpper dessa energikällor utThis research focuses on synthesizing three cobalt complexes by ligands consisting of different conjugated systems and analysing their catalytic properties. These cobalt compounds are to be used to catalyse the reduction of protons generated in the reaction of water splitting. The reverse of water splitting is used in fuel cells and consists of oxidizing hydrogen gas to protons and electrons follo

The Swedish energy market is becoming more and more sustainable, with an increasing volume and number of diversified energy sources being continuously added to the mix. To stabilize the grid frequency, auctions are held to offer energy providers incentives to produce or consume energy on short notice. This paper is applying different multivariate time series models and their ensemble to find relia

There is growing pressure from stakeholders on global corporations to ensure the sustainability of their products throughout the supply chain. At the same time, due to the high complexity and dynamism of supply chains, companies often do not know what actors operate in their supply chains beyond direct suppliers. Supply chain visibility (SCV) and transparency (SCT) are crucial for ensuring respons

Livsmedelsindustrin har stor miljömässig påverkan och uppfyller inte de krav som ställs för att industrin ska betraktas som hållbar. Konsumenterna är en av de viktigaste intressenterna för att kunna implementera hållbar konsumtion. Genom att studera och analysera hur konsumenter skapar värde fås ökad förståelse för vad som driver hållbar konsumtion i livsmedelsindustrin ur konsumentperspektivet. S

Green hydrogen is an advantageous clean energy carrier that enables the decarbonization of hard-to-abate sectors and addresses the intermittency of renewables. However, its global production is currently constrained by inadequate infrastructure, high investment risks, and relatively technological infancy. Failure to scale green hydrogen could hinder decarbonization efforts and climate goals. Recog

Nationalparker utgör ett centralt element i naturvård runt hela jorden. Utöver naturvård så utgör tron på deras positiva effekt för regionalekonomisk utveckling en allt vanligare motivering för att grunda nya nationalparker. Forskningsläget kring omfattningen av sådana effekter är dock oklart och den ekonomiska effekten av nationalparker i Syd-, Väst, och Mellansverige har inte analyserats i någonNational parks are key parts of worldwide conservation initiatives. Increasingly, they are being founded not only to meet conservation goals but also because of their potential positive impact on regional economies. However, the results of previous research are ambiguous when it comes to assessing the magnitude of this effect and no such studies have been conducted for national parks in southern,

Syftet med studien går ut på att undersöka och analysera vilka karaktäristiska egenskaper och färdigheter som en projektledare bör besitta eller utveckla för att lyckas i sin roll. Vidare kommer studien att undersöka projektledarens ledarskapsstil för att få en uppfattning om hur det påverkar ett projekts framgång. Genom att identifiera dessa egenskaper och färdigheter kan arbetet bidra till att ö

The survival and persistence of the threatened Marsh Fritillary butterfly (E. aurinia) is linked to the availability of its host plant, the Devil’s Bit (S. pratensis), which primarily inhibits calcareous grasslands. Previous research has established that mapping the distribution of S. pratensis serves as a reliable indicator for identifying the presence of E. aurinina larvae nests. In this study,

In workplaces, a lot of knowledge is lost when colleagues change positions. What was once obvious to one person can be incomprehensible to the next. This problem has been encountered by Probation Labs Sweden AB with their biochemical instrument, Labbot. Labbot facilitates researchers in automating their protein analysis. It works like a multi-tool where users can perform one or several tasks in a

The objective of this study is to examine the effect of financial literacy on household wealth accumulation among Swedish households. Prior research have suggested that financial literacy plays a significant role in financial decision making. Using household data from The Financial Supervisory Authority (FI) of Sweden and instrumental variable approach, the study aims to isolate the effect of fina

The concrete sector is a major contributor to global greenhouse gas emissions; consumes substantial amounts of natural resources and serves as a significant source of global waste. The Circular Economy approach has been put forward as the solution to these environmental issues, but the overall effectiveness of the approach has been called into question by existing research. The aim of this thesis

During recent decades there has been a rapid growth of volunteer tourism whose nature and impact are increasingly questioned in both literature and media. This study aims to critically compare the intended positive impacts with the potential negative consequences of volunteer tourism. The objective is to gain insight into possible contradictions and harm of the practice. Furthermore, by applying a

På en arbetsmarknad där det blir svårare och svårare för företag att rekrytera rätt kandidater har organisationskulturen blivit en konkurrenskraftig faktor för att attrahera rätt typ av personer. Syftet med denna uppsats är att undersöka vad en sådan organisationskultur kan bestå i: Hur beskriver anställda en god företagskultur och hur upprätthålls den? Forskningen på området förklarar ofta organi

Minoriteter har i alla tider blivit utsatta för att vara annorlunda majoriteten. Samer är ett sådant exempel. Den här studien utforskar hur denna olikhet har kommit att presenteras i svenska video- och filmklipp från 1930- och 1940-tal. Det som står i fokus är hur samerna (minoriteten) har föreställts av svenskar (majoriteten). Detta görs med hjälp av ett antal analytiska begrepp. Rasism, rasifier

This study has been made to further our understanding of which types of horses were sacrificed in Röekillorna, Skedemosse and Stanstorp. But also, to get an idea on how the horses skeletal parts were handled and through that information try to understand the true importance of sacrificing a horse during the iron age, with a main focus on Röekillorna. By studying the osteological material from Röek

The research seeks to answer the research question of How do we interpret the life experiences of the left-behind rural elderly in relation to extended family? And particularly, it inquiries about that: in their family life, what kind of strategies do they apply to navigate the balance between individual and family interests? To answer the question, the research combined neo-familism and life cour

Despite the many use cases for machine learning, it sees minimal usage in Sweden’s public sector today. It is important that the public sector in particular utilizes the most efficient tools available. For this reason, the Department of Employment and Social Services in Malmö has started a project to explore the viability of introducing machine learning to their work. This thesis corresponds to ro
