Large language models have gained widespread use and made its way into numerous parts of everyday life. Paramount interest is therefore on how to use these models correctly and increase their efficiency. This has led research to the field of prompt engineering, which shows a huge difference in accuracy depending on how the user writes their prompt....
This thesis investigates the integration of sentiment analysis from both text and audio data of financial earnings calls, an innovative approach situated at the intersection of Natural Language Processing (NLP), Speech Emotion Recognition (SER), and financial analysis. The core problem addressed is the limited accuracy and depth of sentiment analys...
This report is going to evaluate Matomo, an analytic tool for forms on the web, and how Matomo can be applied to the digital services of Försäkringskassan. Försäkringskassan already has access to Matomo’s services but does not fully utilize them. Before Försäkringskassan can apply Matomo to the fullest they need to ensure that Matomo can be used se...
This study addresses the challenge of identifying anomalies within multivariate time series data, focusing specifically on the operational parameters of gas turbine combustion systems. In search of an effective detection method, the research explores the application of three distinct machine learning methods: the Long Short-Term Memory (LSTM) autoe...
This project aims to develop a portable product using Arduino technology to approximate hearing clinic tests, programmed with IAR Embedded Workbench. Designed for workplace use, the device allows individuals to evaluate their hearing in a quiet room, raising awareness and promoting regular hearing checks. The device should be placed in an environme...
This project investigates the feasibility of migrating from an SQL database utilizing complex stored procedures to a NoSQL database, specifically focusing on the Saab application BAAS. The motivation behind the investigation is that the stored procedures are complex to maintain. The aim is to determine whether such a migration can simplify the data...
Nätverkssäkerheten har blivit viktigare än någonsin med tanke på de allt mer sofistikeradecyberattackerna. Bristande nätverkssäkerhet kan leda till förödande konsekvenser såsomdataförluster, läckage av konfidentiella dokument eller total systemnedgång. Det är en allmänfakta mellan nätverksingenjörer att VLAN är en teknik för att höja säkerheten i n...
Model checking is a formal verification technique for verifying temporal properties in state-transition models. The main problem with using model checking is the state explosion problem, where the number of states in the model can grow exponentially, making verification infeasible. Previous work has tried to mitigate the state explosion problem by ...
The Internet plays an important role in modern society, and its network performance impacts billions of users every day. For many network applications, network latency has a large impact on the quality of experience for the end user. Due to a lack of extensive network latency monitoring, the observability of network latency in real networks is ofte...
Today, the internet connects 66.2% of the world’s population online. Accessibility to digital information is crucial for social inclusion and equal opportunities. In this respect, it is considered to be a fundamental human right. However, most websites contain accessibility errors, creating a significant barrier for users with impairments. Accessib...
