Abstract—Ultra-Wideband (UWB) technology is a low power and high data rate technology for applications like radar imaging, sensor data collection, position localization and medical imaging. In UWB systems, antennas plays a critical role as they are required to be compact and wideband with minimal pulse distortion. This paper present a small three-dimensional volcano smoke antenna, designed and opt

To further clarify the mechanisms maintaining chronic atrial fibrillation (CAF), a method identifying preferable activation patterns of the atria during fibrillation, by time averaging of multiple discrete excitation vectors, was developed. Repeated recordings, each of 56 atrial bipolar electrograms simultaneously acquired during 8 s, were made at multiple sites in the right atrial free wall and t

Denna kandidatuppsats undersöker hur försäkringsbolag arbetar med att skapa tillit till AI-system i skadehandläggningsprocesser. Med utgångspunkt i tidigare forskning om tillit till AI – särskilt begreppen teknisk kvalitet, integritet och mänskliga egenskaper – analyseras tekniska och organisatoriska strategier genom en kvalitativ intervjustudie. Analysen bygger på en systematisk jämförelse mellan

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 This means that the structure of the logic remains outdated and does not take adv

As industrial sectors and digital infrastructure expand, the global demand for high-volume, reliable manufacturing of thermal management solutions like heat exchangers continues to accelerate. This thesis investigates the design and optimization of an automated robotic assembly cell for heat exchanger production at Alfa Laval using Discrete Event Simulation (DES). The primary objective was to defi

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

α-CGRP 8-37 is a peptide fragment of calcitonin gene-related peptide and is commonly used as a CGRP antagonist in pharmacological research. CGRP signaling has been discussed in relation to neuroimmune mechanisms in psoriasis, but a practical development of α-CGRP 8-37 requires analytical methods and formulation strategies that can handle peptide instability, adsorption, and matrix effects. The aim

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

Energy management in cold logistics is critical for sustainable cold chain transportation. However, conventional reactive temperature control strategies often induce excessive energy consumption and mechanical wear due to rigid air temperature tracking and inability to anticipate system thermal dynamics. Guided by the Design Science Research (DSR) methodology, this study proposes a simulation-base

This thesis develops a Fourier-feature DeepONet surrogate model for predicting two-dimensional steady laminar flow fields around a rotating triangular obstacle. The aim is to learn the mapping from the obstacle rotation angle to the corresponding pressure, x-velocity, and y-velocity fields. A CFD dataset containing 121 cases was generated using ANSYS Fluent, covering rotation angles from 0° to 120

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,

Many consumers say they want to shop more sustainably. But most retail websites do not make that easy. Walk through a typical online furniture store, and you will find sustainability information buried in product specifications or tucked away behind a separate filter tab. This happens right when you are already trying to balance price, looks, and whether the thing will actually fit in your living

Milk protein compositions play a pivotal role in physicochemical and technological properties of milk, particularly in rennet coagulation in cheese production. Conventional analytical methods such as sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and liquid chromatography–high resolution mass spectrometry (LC-HRMS) provide detailed protein characterization but require long an

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
