Ända sedan 1800-talet har det stått klart att för den som vill utforma termodynamiska processer finns det oundvikliga kompromisser. Bland de främsta av dessa är att för en värmemotor måste man välja mellan kraft eller effektivitet: en kraftfull motor kan inte vara effektiv, och en väldigt effektiv motor kan inte vara kraftfull. Detta var länge accepterat som en oundviklig konsekvens av termodynamiWe investigate the validity of thermodynamic uncertainty relations (TURs) in a strongly correlated quantum dot system operating in the Kondo regime. TURs place fundamental bounds on the trade-off between precision and dissipation in non-equilibrium systems, and while these bounds are rigorously proven for classical stochastic dynamics, they are not guaranteed to hold in quantum-coherent, strongly

In the post-pandemic era, the hotel industry is gradually recovering alongside the broader tourism sector. As a key component of tourism, hotel quality plays a vital role in shaping guest experiences. This thesis examines consumer value in the context of a well-developed hotel industry by focusing on the St. Regis hotel in Macao as a case study. The research investigates what types of consumer val

Kvantnyckeldistribution är ett alternativ till traditionella metoder för att distribuera krypteringsnycklar. Till skillnad från de traditionella metoderna är kvantnyckeldistribution säkert även mot kvantdatorer. Olika typer av fel i sändare och mottagares laboratorier kan dock påverka säkerheten hos systemet. Större och mer generella fel leder till sämre säkerhet. Information om nyckeln kan också With the rise of quantum computers that can break traditional key distribution protocols for cryptography, new methods are needed. In Quantum Key Distribution (QKD), quantum physics is used to create and distribute a secret key between honest parties. This thesis focuses on the well-known BB84 protocol. The sender (Alice) sends quantum states to the receiver (Bob) who measures the states. Alice’s

Automatisk sömnklassificering med hjälp av artificiell intelligens. Sömn är avgörande för vår hälsa, men att manuellt analysera sömn är både tidskrävande och kostsamt. Genom att använda artificiell intelligens har vi utvecklat en metod som automatiskt kan klassificera sömnstadier baserat på EEG-signaler, vilket kan effektivisera sömnanalys. Människor spenderar ungefär en tredjedel av sina liv sHistorically, sleep stage classification has relied on manual scoring performed by experienced professionals. In recent years, the emergence of machine learning has enabled the automation of this process, thus saving both time and resources. Many of these sleep staging models depend on data which already has been annotated by a professional, but a few try to exploit the vast amount of unlabelled d

Purpose: The purpose of this paper is to examine the effects of nostalgic short-form video on visit intention, including the interaction of nostalgia to perceived self-continuity, attitude towards location, and previous travel experiences. Methodology: The study uses an experimental design that compares individuals’ responses to nostalgic vs non-nostalgic short-form video. Multiple regression an

Railway networks are a critical component of modern transportation systems, but their efficiency is often challenged by disturbances that propagate through the network, leading to delays and reduced punctuality. This thesis investigates station-level disturbances and their duration, with the aim of developing a foundation for an online tool that can estimate disturbance durations. Using historical

This research explores the socio-economic impacts of flooding on women's livelihoods in Banjul, The Gambia, a city that is increasingly vulnerable to climate change and flooding disasters. With increasing flooding in coastal regions, Banjul is among the cities with significant challenges, particularly for women, who are usually marginalized and disproportionately affected in case of disasters.

Geospatial data is becoming increasingly important as artificial intelligence develops rapidly, creating new opportunities in the field of Geographic Information Systems. The thesis investigates the possibility of establishing a method to automatically calibrate a network camera’s geolocation and heading direction by using a camera view image and its corresponding satellite image. The aim is to lo

Depression är ett stort problem i samhället idag, det vanligaste läkemedlet som används för behandling av det är någon typ av Selektiva serotoninåterupptagshämmare (SSRI). Dessa läkemedel är effektiva men kräver regelbundna doser och har otrevliga sidoeffekter såsom viktuppgång, emotionell avtrubbning och sexuell dysfunktion. Psilocybin har nyligen fått uppmärksamhet som ett alternativ till dessThe scientific interest in psilocybin has recently been reignited, the research community has once again begun to investigate the promising potential that psilocybin offers in the area off treatment of depression and PTSD. An obstacle to the research of psilocybin is that today pharmaceutical grade psilocybin is produced using an inefficient and thus costly synthetic process. This hampers the rese

Så kan skogsägare bromsa klimatförändringarna – och samtidigt få betalt för det. Privata skogsägare kan spela en nyckelroll i Sveriges klimatarbete – men då krävs ersättning och tydligare regler. Klimatförändringarna har ökat behovet av lösningar som både minskar utsläpp och binder koldioxid. Skogen är en naturlig kolsänka – alltså ett ekosystem som lagrar koldioxid – och därför är skogsbruket i Since pre-industrial times, increased greenhouse gases in the atmosphere has contributed to climate change affecting all ecosystems. As a result, global and national commitments have been made to reduce emissions by enhancing the number and effectiveness of carbon sinks. To meet the national climate targets, Sweden has proposed financial compensation for forest owners who postpone harvesting. This

In the West Bank, a context of protracted displacement and institutional fragmentation, internally displaced persons remain structurally excluded from both humanitarian and national protection systems. Amid fragmented aid architecture and legal ambiguity, the Humanitarian-Development-Peace Nexus has been promoted as a framework for institutional coherence. Yet, it remains mired in a contested spac

Sweden’s post-war development positioned it among Europe’s most motorised countries, contributing to high car ownership and widespread reliance on private vehicles. While cars remain essential to modern life, their overuse challenges national climate goals and public health. Efforts to reduce car use have increasingly focused on promoting sustainable al ternatives such as walking, cycling, and pub

The resistivity of the semi-conducting material in high voltage direct current cables were studied under a variety of conditions. A wide theoretical background was also created, summarizing previous works within the field and providing useful explanations for the characteristics seen in the results. The semi-conducting material works as a protective shield for the insulation of the cable, protecti
