Sannolikheten att det finns en högtalare nära dig är hög. De finns där för att spela musik i en affär, för att meddela att brandlarmet har gått i byggnaden du befinner dig i eller för att berätta att tåget du ska åka med är inställt. Alla högtalare låter på lite olika sätt, de har sina egna skavanker som gör att en viss frekvens kanske låter lite mer än andra. I detta projekt har vi funderat på deThis thesis investigates the performance and feasibility of passive and active analog frequency compensation filters for audio signal processing in a distributed speaker system. One passive and one active circuit topology were investigated more thoroughly and then the active filter was realized on a PCB and evaluated with electrical, thermal and acoustic measurements. The work also resulted in tw

Artificiell intelligens omvandlar i allt högre grad organisationskommunikation genom att omforma uppgifter och interaktioner som tidigare hanterats av människor, vilket leder till strategiska förändringar i rekryteringsarbetet. Den här studien utforskar hur medarbetare inom rekrytering och marknadsföring skapar mening kring AI:s betydelse, särskilt i relation till kommunikationsprocesser, employerArtificial intelligence is increasingly transforming organizational communication by reshaping tasks and interactions once managed by humans, prompting strategic shifts in recruitment workflows. This study explores how employees in recruitment and marketing make sense of AI’s significance, particularly in relation to communication processes, employer branding and professional identity. Through an

This thesis investigates the effect of policy measures on macroeconomic indicators in the EU member countries during the COVID-19 pandemic. The study uses data on four different policy measures as key independent variables, that together with control variables are regressed against three dependent variables, which are indicators of the economic situation of a country. The variables studied are rea

I investigate how temperature variations influence time allocation for the consumption of various goods and services, focusing on essential and non-essential consumption. Using data from the American Time Use Survey (ATUS) and National Oceanic and AtmosphericAdministration (NOAA)'s weather records, I employ fixed-effects regression models to estimate the nonlinear impact of maximum temperature

The purpose of this study was to investigate when human error is deemed to be culpable in a context of aviation and Just Culture. The study was conducted through a literature review together with a qualitative interview study with stakeholders in Swedish airlines and relevant authorities. For a long time there has been a tendency to see humans as faulty and blameworthy, while safety scholars sugge

In this master’s thesis I aim to produce knowledge concerning the perceived expertise and cognitive authority of generative AI models, specifically in regard to health, politics and the environment. This problem is important to investigate in order to better understand how people interact with synthetic information, both as a reliable source and as an example of mis- or disinformation. Furthermore

This thesis studies the impact that seagrass meadows have in terms of attenuating incoming wave heights and mitigating coastal erosion. Specifically, this study seeks to investigate how seagrass meadows impact the coastline by looking at the longshore sediment transport, which has been identified as the key erosion process. This will be done by looking at the case study of Le Morne on Mauritius. T

Carbon leakage resulting from asymmetric climate policies undermines the effectiveness of global climate governance. This paper examines whether China’s national Emissions Trading System, launched in 2021, has induced carbon leakage through outward foreign direct investment at the firm level. Using firm-level data and a PSM-DID approach, this study finds no evidence of investment-driven carbon lea

This thesis explores the challenges associated with electronic legal deposit in Sweden, focusing on both its historical development and current legal framework. While the existing legislation for electronic legal deposit was introduced in 2012, it has not kept pace with technological advancements, resulting in significant gaps in the collection and preservation of digital publications. The study a

Klockdrift kan orsaka problem vid datainsamling och negativt påverka kvaliteten på insamlad data. Denna klockdrift är vanligt förekommande i de klockor som används i digitala och självrapporterande sensorer och beror på kvartsoscillatorns kvalitet och konstruktion. I sammanhang där vanliga synkroniseringsprotokoll inte kan användas krävs en lösning som tillåter att insamlad data korrigeras i efte

Over time, Sweden has demonstrated a stable policy line across governments, marked by a critical view of further EU integration in the area of security and defence. There is a strong tendency in Sweden to initially reject EU proposals in this domain and widely advocated that this area is best managed at a national level. Over the past seven years, Sweden has initially rejected several EU proposals

The digital transformation impacts the archive sector, the threat picture is rising and creating new demands for information security. This master's thesis investigates how modern municipal archivists manage information security and the challenges they face in this evolving landscape. The study aims to complement existing research by exploring how archivists navigate the growing information se

During the last ten years, many reports have highlighted the increasingly stressed working environment in Swedish public libraries. Librarians are experiencing elevated stress levels and encountering various forms of disorder in their daily work. The purpose of this thesis is to investigate and contribute with insights of how librarians perceive and manage different forms of disorder in public l

This thesis explores how interaction between humans and generative artificial intelligence can be understood as an entangled, co-constitutive practice of information production. Drawing on Karen Barad’s theory of agential realism and Luciano Floridi’s information ethics, the study examines not only how such interaction unfolds, but also what ethical implications it may carry. The empirical materia

Children and young people with non-normative functionality are, according to the Swedish Library Act, prioritised groups. Still, many libraries lack inclusive and accessible services and resources aimed at these groups. This thesis explores the Apple Shelf – a section in Swedish public libraries intended to create an inclusive environment and offer relevant resources that address the needs of thes

The primary aim of the paper is to evaluate whether listed Nordic serial acquirers create short-term abnormal returns at the time of acquisition announcements, and also to determine if serial acquirers experience diminishing returns following additional acquisition announcements, and if concentrated family ownership mitigates the diminishing returns. Theoretical perspectives used include agency t

Climate change is expected to increasingly challenge agricultural systems worldwide, and Sweden is no exception. Although agriculture represents a relatively small share of national employment, it plays a critical role in food security, particularly in Skåne County, which contains some of the country’s most productive farmland. This thesis investigates how deviations from long-term average tempera

Stora språkmodeller (LLM) har uppvisat anmärkningsvärda förmågor inom en rad olika uppgifter inom naturlig språkbehandling (NLP). Deras prestanda är dock mycket känslig för den inledande prompt som används för att fråga dem. Manuell promptkonstruktion, även om den är effektiv, är ofta tidskrävande och kräver betydande expertis. Denna avhandling undersöker promptoptimering, med fokus på en automatiLarge Language Models (LLMs) have demonstrated remarkable capabilities across various Natural Language Processing (NLP) tasks. However, their performance is highly sensitive to the input prompt used to query them. Manual prompt engineering, while effective, is often time-consuming and requires significant expertise. This thesis investigates Prompt Optimization, focusing on a closed-loop, automated

This study presents a mineralogical, textural and structural assessment of the Cambrian Faludden Sandstone Member (Borgholm Formation) and Lower Silurian mudstone (unspecified formation), for their potential use as reservoir and caprock, respectively, for deep carbon storage in the Swedish sector of the Baltic Sea subsurface. The study was performed on two drillcores from the island of Gotland, No

There is an expanding literature on the economic long-term effects of exogenous shocks such as armed conflict and economic crises. While some studies find evidence of poverty traps, the majority support the neoclassical prediction of eventual catch-up growth. This study contributes to the debate by examining Cambodia, which arguably became the most severely bombed country in history and site of on
