Överföringen av logiska program från äldre styrsystem till nyare är ett omfattande arbete som, oavsett teknisk utveckling, fortfarande är en betydande manuell börda. Visserligen finns det verktyg som kan göra en automat-konvertering, men dessa tenderar att genomföra en 1:1-konvertering, vilket innebär att den nya logiken behåller samma föråldrade struktur och inte drar nytta av moderna funktioner The transfer of control logic and system implementations from older to newer control systems is a substantial undertaking that, despite technological advancements, remains largely a manual effort. While there are tools available that perform automatic conversions, these tend to apply a one-to-one conversion strategy. This means that the structure of the logic remains outdated and does not take adv

Emergency department (ED) wait times can be long, and not all patients can safely wait for treatment. Therefore, an effective emergency triage system is required to prioritize patients according to the urgency of their condition upon arrival at the ED. Assessing a patient’s level of urgency without access to complete physiological measurements is a complex task that is currently performed by nurse

The tea sector is one of Kenya's most important industries, with a big impact on the country's economy and socio-economic development. At the same time, tea manufacturing is highly energy-intensive and strongly affected by electricity tariffs and high production costs. Due to the favorable weather conditions and growing renewable energy ambitions in Kenya, Solar Photovoltaic (PV) systems p

Sveriges elsystem genomgår en förändring i takt med att andelen väderberoende kraftproduktion ökar. Kraftvärmeverk, som traditionellt haft en tydlig roll som planerbar kraft, möter ett allt hårdare ekonomiskt tryck när marginalerna på spotmarknaden pressas. Detta examensarbete undersöker hur ett kraftvärmeverk i elområde SE3 kan förbättra sin lönsamhet genom deltagande på mFRR D-1 kapacitetsmarknaSweden’s electricity system is undergoing change as the share of weather-dependent power production increases. Combined heat and power (CHP) plants, traditionally valued for their dispatchability, face growing economic pressure as spot market margins tighten. This thesis investigates how a CHP plant in Swedish electricity area SE3 can improve its profitability by participating in the manual freque

This thesis investigates the design and evaluation of Large Language Model (LLM) agent assistants for industrial maintenance, developed in cooperation with SSAB. The study focuses on identifying what combinations of tools and architectures best serve the needs of maintenance technicians, with an emphasis on practical usability and factual correctness. Multiple agents were developed and compared,

Cybersecurity has never been more relevant than it is today, as attacks become increasingly sophisticated. To keep devices safe from threats, a new type of smart firewall has become an active area of research. This type of firewall can dynami- cally configure itself based on incoming network traffic using reinforcement learn- ing. This research has shown promising results; however, its impact on r

Non-terrestrial networks (NTNs) are expected to become an important component of future sixth-generation (6G) wireless systems by extending broadband coverage to remote, maritime, aerial, and underserved areas. Among different NTN platforms, low Earth orbit (LEO) satellite constellations are particularly attractive due to their lower propagation delay compared with geostationary systems. However,

This thesis presents an automated pipeline developed for reconstructing the 3D flight trajectories of bats navigating a cave environment purely from multi-channel audio recordings. The pipeline was developed and validated using the Ushichka dataset which contains multiple simultaneous audio and video recordings of bats in their natural habitat, the Orlova Chuka cave in Bulgaria. The proposed pipel

This project involved the testing and establishment of a base combustion procedure for the newly acquired Raddec Gen IV PYROLYSER and focused on the optimization and correction of the laboratory’s previous liquid scintillation counting (LSC) procedure using the Hidex 300 SL. The pyrolyser was verified to be operational and achieve satisfactory and consistent recoveries across the 6 combustion tub

Studien undersöker hur vi kan förstå AI för emotionellt- eller mentalt stöd, genom användares egna berättelser och diskussioner om denna typ av AI-användning. Syftet med undersökningen är att bidra till fördjupad sociologisk kunskap om hur användare upplever och tolkar stödet för att det ska bli meningsfullt och användbart för emotionellt- eller mentalt välbefinnande. Ämnet är fortfarande relativt

När ett nedslag gräver upp och modifierar Mars yta, genom att medföra material från djupare delar till ytan, öppnar det fönster ner till äldre geologi. Att försöka förstå ytegenskaper på Mars och hur källmaterialet beter sig vid ett nedslag kräver en metod från flera perspektiv. Tidigare forskning har främst fokuserat på ejecta och ejektamorfologi som en indikator på ytegenskaper. Däremot kan ävenWhen an impact excavates and modifies the Martian surface, by bringing deeper lying material to the surface, it opens a window into past geology. Trying to understand surface properties on Mars and how target material behaves during impact requires a multi-view approach. Previous research has focused mainly on ejecta emplacement and morphologies as a proxy for surface properties. However, interior

Direct-to-Device (D2D) communication in Non-Terrestrial Networks (NTNs) enables smartphones to connect directly to satellites, extending wireless coverage beyond terrestrial networks. This thesis presents the design of a smartphone antenna optimized for NTN operation, followed by a link budget analysis and Electromagnetic Field (EMF) exposure assessment. The proposed solution is a dual-band circu

The establishment of innovation ecosystems has become an increasingly prevalent strategy for fostering territorial, economic and social development. However, the existing literature provides limited insights into the strategic conditions that enable the emergence of such ecosystems. This paper addresses this gap by identifying the critical elements and mechanisms underpinning their creation. Speci

Large language models (LLMs) and their applications in low-resource languages (such as in Vietnamese) are limited due to lack of training data and benchmarking datasets. This paper introduces a practical real-world implementation of a question answering system for Vietnamese, called ViGPTQA, leveraging the power of LLM. Since there is no effective LLM in Vietnamese to date, we also propose, evalua

We present a novel deep neural network architecture for representing robot experiences in an episodic-like memory that facilitates encoding, recalling, and predicting action experiences. Our proposed unsupervised deep episodic memory model as follows: First, encodes observed actions in a latent vector space and, based on this latent encoding, second, infers most similar episodes previously experie

We describe an experimental setup for non-linear interaction and propagation of ultrashort and intense x-ray free-electron laser (XFEL) pulses in a dense gas. It allows one to provide high, but adjustable, target-gas pressures of up to 6 bar within a vacuum environment of 3∙10− 3 mbar or better. The setup enables investigation of intense x-ray propagation in an optically thick medium with minimal

We have generated two reporter plasmids that either monitor expression of human papillomavirus type 16 (HPV16) E2 mRNAs using splice site SA2709 or HPV16 E1C mRNAs utilizing splice site SA2582. In plasmid pE2sLuc, the entire E2 open reading frame was replaced by the secreted luciferase (sLuc) reporter gene and in the pE1nLuc plasmid the E1/E1C open reading frame was fused in frame with the nanoluc
