Batterilager i elnätet blir vanligare och större, till den grad att det är aktuellt med direk- tanslutning till transmissionsnätet. Som en del av elektrifieringen kan batterier spela en viktig roll för nätets stabilitet − de kan snabbt och exakt leverera mycket effekt, både in i och ut ur nätet. Detta gör dem särskilt lämpade för snabba reserver, såsom FCR-D och FFR. I varje punkt i elnätet finnsBattery Energy Storage Systems (BESSs) are becoming larger, to the extent that they are relevant to consider for direct connection to the transmission network. With increasing electrification, batteries could be useful for grid stability purposes. Their ability to rapidly and accurately deliver high power, both to and from the grid, makes them well-suited for fast system services such as FCR-D and

This master's thesis investigates the commercialization of video-capture-based sports technology in the Swedish lower-tier sports sector, a segment where adoption remains limited despite the growing relevance of such tools in elite contexts. Several scholars have highlighted the need for further research on how high-end technologies can be adapted to resource-constrained environments. This the

Den effektiva marknadshypotesen säger att det inte går att finna någon form av strategi som riskjusterat avkastar bättre än de finansiella marknaderna. Vidare har det påvisats att autokorrelationen för enskilda aktier historiskt varit låg vilket tyder på att exempelvis teknisk analys torde tillföra lite värde för någon som ämnar avkasta bättre riskjusterat än den breda marknaden. I denna uppsats tIn this thesis it was evaluated whether it is possible to risk-adjusted outperform the naive, buy and hold, approach for Swedish, listed investment companies. The key metric for this objective was, first and foremost, the Sharpe ratio and secondly the Sortino ratio. To do this, a random forest model was used along with a regime filter. The prediction horizon was one day meaning that at the end of

As the demand for secure software and hardware solutions increase in our modern digitalized society, the importance of reliable and cost-effective product testing is apparent. One such testing technique is fuzzing, which involves generating large amounts of malformed and randomized data to stress test system interfaces. This study aimed to compare traditional fuzzing methods to modern approaches a

This thesis focuses on designing a new university hospital in Lund, addressing both technical demands and human needs. It explores the question: “How can the new hospital and intensive care unit (ICU) in Lund be designed in a way that fulfills all the technical demands, but also the more immaterial human needs?” Located on Smörlyckan, the design aligns with the competition for the “Nytt Sjukhusomr

En funktion är inom matematiken ett samband mellan två kvantiteter. Man kan se det som en maskin som tar in ett tal och ger tillbaka ett annat. Ett exempel på en funktion är hastigheten av en bil som en funktion av tid: du ger funktionen en tidpunkt, och funktionen ger tillbaka bilens hastighet vid denna tidpunkt. Inom matematiken är man ofta intresserad av att studera funktioner med vissa givna eWe introduce the basic theory of vector-valued reproducing kernel Hilbert spaces, and use this language to prove the classical Pick interpolation theorem using the commutant lifting theorem applied to operators on the Hardy space H^2(D). Two very general versions of the commutant lifting theorem due to Shimorin are then proved for vector-valued reproducing kernel Hilbert spaces, and as a corollary

This thesis investigates superconductivity in novel planar Josephson junctions fabricated from a hybrid Al/EuS/2DEG (InGaAs/InAs/InGaAs) heterostructure. Using electron-beam lithography, selective etching, and atomic layer deposition, Josephson junction devices, constrictions, and SQUID geometries were fabricated and a selection of the devices were characterized at millikelvin temperatures. The me

This introductory chapter outlines the foundations of the study by contextualizing the role of legitimacy, corporate responsibility, and crisis communication in contemporary global business. It begins by establishing the theoretical significance of organizational legitimacy, particularly in ethically sensitive industries such as infant nutrition. The chapter problematizes the disjunction betwe

Amyloid fibrillering, en process där peptider (små protein) klumpas ihop, är idag associerat med en rad sjukdomar såsom Alzheimers sjukdom och diabetes typ 2. En peptid som är associerad med diabetes typ 2 är IAPP. Peptiden har hittats fibrillerad i bukspottskörteln i många patienter med diabetes typ 2. I tidigare studier har det hittats en koppling mellan små plaster, så kallade nanoplaster, och The impact of nanoparticles on amyloid fibrillation has been studied for some time due to the amount of nanoparticles that can be found in nature due to human release. Previous studies have shown that different nanoparticles may affect the length of the lag phase of the fibrillation process. This has been studied on peptides such as amyloid beta and islet amyloid polypeptide. Research has shown th

The concept of the library has evolved over time, adapting to the changing needs of society and there are various types of libraries, from public institutions to private collections. Today, digitalization is reshaping how we access information and interact with the world, yet libraries and books continue to hold an essential role as spaces for reflection, learning, and community connection. Smal

Denna kandidatuppsats undersöker hur medelstora och stora svenska företag uppfattar datakvalitet vid design och implementering av AI-drivna chattbotar för internt bruk. Studien bygger på fem semistrukturerade intervjuer med yrkesverksamma som varit direkt involverade i utvecklingsarbetet och belyser hur organisationer ser på faktorer som datans noggrannhet, fullständighet och tillförlitlighet. ResThis bachelor’s thesis investigates how medium and large Swedish enterprises perceive data quality during the design and implementation of AI-powered chatbots for internal use. Through five semi-structured interviews with professionals directly involved in the chatbot development, the study explores organisational perspectives on data accuracy, completeness, and reliability, as well as key drivers

This study explores how airports develop and repeat specific behaviors that help them remain innovative over time. As digital needs increase, climate regulations tighten, and passengers demand better experiences, airports must remain dependable while also finding ways to adapt. This study examines the behaviors and habits that make innovation a part of everyday work. To further understand this, tw

Vad kan stoppa oss från att hitta mörk materia med LDMX? När astronomer tittar på de största objekten i vårt universum ser de att stora strukturer, så som som galaxer och galaxkluster, inte rör sig som de förväntar sig. Det visar sig att det finnas en stor mängd extra materia som vi inte kan se. Denna osynliga materia kallar vi ’mörk materia’. Många teorier för vad mörk materia består av har lagtAccording to astronomical observations of galaxies and other large scale dynamics, the universe contains more mass than what is visible. This missing mass is called "dark matter" and have been a subject of study for physicists for decades. The Light Dark Matter eXperiment (LDMX) is a proposed experiment with the purpose to search for dark matter in a low mass range that not many experime

Inom de översättnings- och litteraturvetenskapliga fälten i Sverige saknas en tolkningstradition som tar hänsyn till översatta texters särskilda villkor samtidigt som de inkluderar dessa som en del av författaröversättares totala litterära produktion. Syftet med denna studie är därför att visa hur en analys som tar det översättande skrivandet i beaktning möjliggör en fördjupad förståelse av det li
