Keyword spotting (KWS) is an essential function in always-on voice-interface systems,where a low-power detector continuously monitors audio streams and activates subsequent speech-processing modules only when a target keyword is detected. This thesis presents the design and evaluation of a 40 nm CMOS ultralow- power KWS accelerator that integrates a Mel-Frequency Cepstral Coefficient (MFCC) front-
The Lund string model, which is implemented in PYTHIA, describes the hadronization process by representing the color electric field between a quark-antiquark pair as a massless, relativistic string. In the string shoving extension, the strings will have a Gaussian profile and will repel each other when they interact, acting like classical objects. When two strings interact and are positioned perpe
Air quality is affected by airborne particles and gases such as PM2.5, volatile organic compounds (VOC), and nitrogen oxides (NOx), as well as environmental factors such as humidity and temperature, all of which influence human health and the spread of airborne diseases. While research grade air quality instruments provide accurate measurements, they are often large, expensive and difficult to uti
The political landscape in Germany changed dramatically when Alternative für Deutschland became the third largest party. The party started out as eurosceptic but has developed its ideology into being anti-migration and radical right populist while experiencing internal conflicts and becoming controversial in mainstream media. This culminated when the party was classified as right-wing extremist by
This thesis examines the transformation of Finnish international identity between Finland’s accession to the EU in 1995 and its membership in NATO in 2023. The study is significant as Finland’s NATO accession has frequently been portrayed as a sudden and unprecedented rupture in Finnish foreign and security policy following Russia’s full-scale invasion of Ukraine in 2022. Challenging this interpre
Youth crime is a significant social problem, and preventive work targeting young people at risk of criminality is currently of central importance. This study examines how the new Swedish Social Services Act (2025:400) influences preventive social work in relation to risk and protective factors. By exploring social workers’ experiences, this study aims to contribute to a deeper understanding of pre
This study aimed to find and explore potential relations between the consumption of news on social media and psychological distress in young adults through the term news-related posts on social media. This quantitative survey study utilized a sample consisting of 337 students aged between 18 and 30 studying in Lund, Sweden. Information concerning daily news-related social media posts consumption a
This thesis investigates the development of an object-oriented modular framework for PLC systems, intended for use at Etteplan, an international engineering consultancy. The thesis was motivated by recurring challenges in PLC projects, including unclear program flows, low code reusability, and limited scalability. These issues justify the need for a standardized framework grounded in the IEC 61131
This thesis investigates how players of Grand Theft Auto V and Red Dead Redemption 2 morally make sense of in-game crime. The study is motivated by the fact that video games are important cultural spaces where players not only watch crime and violence but also participate in them through play. While previous research on violent video games has often focused on aggression and media effects, this th
The legality requirement under the EU Regulation on Deforestation-free Products (EUDR) raises important interpretative questions concerning the nature and scope of the due diligence obligations imposed on companies operating in global value chains (GVCs). While the EUDR was primarily adopted as an environmental instrument aimed at reducing the European Union’s contribution to global deforestation
This thesis compares two qualities of flint, one more fine-grained and one more coarse-grained, from the Late Mesolithic Ertebølle site Skateholm I in Scania, Sweden. This in order to investigate what roles the different qualities of flint had in the technological organisation relating to raw material acquisition, choice of technology, and end-product goals. Through a technical analysis of the fli
Messenger RNA (mRNA) plays a central role in gene expression by transferring genetic information from DNA to the translational machinery for protein synthesis. Recent advances in RNA therapeutics and synthetic biology have highlighted the importance of untranslated regions (UTRs) and RNA secondary structures in regulating mRNA stability and translational efficiency. In the present study, engineere
Professional judgement is a complex phenomenon to comprehend and is often forgotten when discussing the importance of knowledge use in discretionary decision-making within Swedish child welfare. Therefore, the study had a dual purpose that aimed to foster a deeper understanding of professional judgement in Swedish child welfare; theoretically, the study aimed to explore the meanings of professiona
This qualitative study aims to explore how relatives of individuals with addiction prob- lems experience and manage their sense of responsibility, and how the balance between their own needs and those of the addicted person is renegotiated over time. The empirical data consists of six semi-structured interviews with relatives recruited through the self-help organization Al-Anon. The material was a
This thesis examines the extent to which EU directives on information and consultation enable employees, through employees’ representatives, to influence employer decision-making before final decisions are adopted, particularly in situations involving restructuring and collective redundancies. The analysis focuses on four central directives within the EU framework: the Information and Consultation
Stora språkmodeller (LLM:er) används i allt större utsträckning som en viktig teknologi i agentbaserade system för mjukvarurelaterade uppgifter. Dessa system är avsedda för att kunna hantera långsiktiga uppgifter och kan bestå av ett flertal interagerande agenter som arbetar mot gemensamma mål. I dessa scenarier förväntas agenterna arbeta med samma kodbas över flera sessioner och utvecklingscyklerLarge Language Models (LLMs) are increasingly being used as a key technology in agent-based systems for software-related tasks. These systems are intended to support long-term tasks and may consist of multiple interacting agents working towards shared goals. In these scenarios, agents are expected to work on the same codebase over multiple sessions and development cycles. In long-term software dev
I varje designprojekt bör man tänka på miljöaspekten av det man gör och just detta projekt fokuserar på textilier i förhållande till de möbler de fästs vid. Att fästa tyg är en extra svår utmaning när det kommer till möbeldesign. Ofta används lim, spik eller häftstift, vilket skadar både tyg och den underliggande träkonstruktionen. Genom analoga prototypmetoder utforskar detta projekt alternativa Every design project should consider sustainability, and this one focuses on textiles in relation to furniture. A particularly difficult problem with furniture design is textile attachment. The dressing of a piece of furniture or a seat is usually done using glue and nails, which are invasive both on the fabric and the wood. Through analogue prototyping, this project explores alternative ways to d
Radio Frequency Integrated Circuits (RFICs) play a crucial role in modern wireless communica- tion systems. However, they can achieve high performance only when their internal registers are dynamically and precisely configured. To maintain reliable control while operating in complex multi-antenna environments, several interface techniques have been developed, among which the Serial Peripheral Inte
This thesis examines Ataa, a contemporary Syrian children’s magazine produced by ATAA Humanitarian Relief Association, through six consecutive issues published between June 2024 and September 2025. It asks how the magazine stages adult authority, constructs an implied child reader, normalises an ideal child, justifies norms, and offers frames of belonging around the politically significant period
This thesis examines the secondary exchange of transferable service access on Xianyu, a Chinese C2C platform increasingly used not only for second-hand goods but also for service-related deals among consumers. These include practices such as restaurant proxy ordering, discount-mediated ordering, alternative booking routes, and membership-based privileges. The study explores how participants find,
