The integration of renewable energy sources into modern power grids necessitates the use of power electronic converters capable of handling high voltages. Multilevel converters offer advantages compared to traditional 2-level converters by provid- ing multiple voltage levels, improved efficiency, and better power quality. However, maintaining balanced DC link voltages presents additional complexit
This project is focusing on one of the underlying issues within the plumbing industry (called “Värme Ventilation Sanitet” in Sweden). Strain injuries was the focus of this project to find a solution and discover the reasons to why these injuries keeps happening. The project then goes into a suggestion of which direction the industry might need to take to become better. Getting a solution to the in
Alfa Laval är marknadsledande på teknologin packningsförsedda plattvärmeväxlare (GPHE). För att behålla sin position som marknadsledare inom GPHE-sektorn så utför Alfa Laval regelbundet designstudier. Designstudierna utförs för att undersöka nya lösningar och få inspiration till nya möjliga funktioner. Alfa Laval strävar alltid efter att förbättra sina produkter med avseende på många faktorer, exeAlfa Laval is the market leader within gasketed plate heat exchanger (GPHE) technology. To remain the leader of the GPHE sector, Alfa Laval regularly performs design studies to investigate new solutions and find inspiration for possible functions. Alfa Laval always work to improve their products, regarding many aspects, such as manufacturability, distribution, and maintenance as well as sustainabi
In the capitalist system, there is a need to envision alternatives that advocate for a more just and sustainable world. Alternative scholarships, such as degrowth, aim to counter the hegemonic narrative of food commodification by promoting practices that put social and environmental well-being at the forefront. This ethnographic research outlines the alternative strategies of tackling food waste a
This study will examine how fashion consumption looks on Tiktok among young women aged 18 - 19 years in Sweden. The aim is to find out which factors influence the target group's fashion consumption on Tiktok and in which specific ways Tiktok contributes to the target group's fashion consumption. To answer these questions, we will use a quantitative survey which will then be analyzed with a
Buildings worldwide account for 30% of energy consumption and Heating, Ventilation and Air Conditioning (HVAC) represent roughly 38% of a building’s consumption. Therefore, energy savings are crucial for sustainability. The complexity of buildings, with diverse physical domains and large-scale components, presents challenges to achieving energy-efficient operation. Implementing high-performance co
The aim of this thesis was to investigate, develop and implement an Advanced Driver Assistance System (ADAS) feature for an ultra-light electric vehicle, focusing specifically on an Automatic Emergency Brake (AEB). The fundamental requirements, for an ultra-light electric vehicle, were found and investigated through experiments. A person detection algorithm with camera and LiDAR was developed with
This paper employs a biopolitical framework to critically analyse Swedish International Development Cooperation Agency’s (Sida) development and humanitarian policies, focusing on how these align with broader biopolitical strategies aimed to shape the lives of populations in recipient countries. Through a critical discourse analysis of four key policy documents, the study addresses the central ques
The construction and demolition industry are annually responsible for 40% of the total amount of waste generated in Sweden. The problem facing the industry is that a very large portion of the waste is disposed of in landfills, and only a very small portion is recycled and reused. The purpose of this study is to investigate how the construction industry can become more circular and sustainable over
This research builds on the assertion that spirituality can be beneficial to human-wellbeing and in creating nature-connection. Applying that notion within the historical context of Christianity and its ties to the work-ethics of capitalism, the paper presents a case-study of the Threeclover Church, a Protestant Green Church in Denmark’s capital region. The aim is to gain further understanding of
Operational systems, such as industrial automation, autonomous vehicles, and larger air/sea/landcrafts, often contain a large number of heavily connected systems with real-time requirements for their functionality. For such systems, detecting and responding to anomalies is both challenging and crucial. Until recently, such anomalies were monitored using heuristic methods, or even humans monitoring
The wide adoption of machine learning (ML) models in resource-constrained devices for complex vision tasks is contingent on improved computational efficiency. Quantization is a tool for model compression in which weights and activations are approximated with low-precision datatypes, to achieve a smaller model with reduced latency and memory usage. In this thesis, we seek to apply post-training mix
In the field of automatic control, embedded Model Predictive Control (MPC) presents significant advantages, including efficiency, constraint incorporation, and non-causal setpoint handling. Despite its potential, the implementation of MPC in resource-constrained environments remains challenging due to its computational demands. This thesis explores the design and implementation of MPC within ABB’s
Buildings worldwide account for roughly 40% of the total energy consumption which boils down to generating 30% of the total carbon dioxide emissions. Heating, Ventilation, and Air Conditioning (HVAC) systems are the largest consumers of energy within these structures. The complexity of building cooling systems poses significant challenges for achieving optimal control. Conventional approaches to i
As the global environment gradually deteriorates, developing green technology innovations for enterprises has become an important goal. The ESG concept of advocating sustainable development has steadily received attention. Therefore, it is essential to understand the relationship between ESG and green technology innovations. This thesis aims to explore whether the environmental, social, and govern
The following thesis is an attempt to analyse the concept of narrative in and around retellings of the events surrounding Czechoslovakia during the First World War and how they are subsequently depicted. This is done by primarily looking at three primary source materials: in English Czech historiography from the past 20 years, an autobiography from WWI and a modern video game on the same subject.
This thesis explores the discursive depiction of life in Portugual from the perspective of lifestyle migrants and digital nomads on TikTok. The aim of this thesis is to uncover the motivations of foreigners to live in Portugal, lifestyle migrants’ integration into Portuguese society, and their acknowledgement of the growing gentrification issues in Portugal. The method used in this study is Norman
This paper examines what effect recent minimum wage increases have had on poverty rates in U.S. states. In the past fifteen years, some states have experienced substantial minimum wage increases while others have seen smaller increases or no changes at all. First, we review some theoretical arguments for and against increases in the minimum wage, discussing its potential effects on unemployment an
