Resource consumption is becoming increasingly scarce with an increase in the global population. Due to the increased resource consumption, the current linear economy model is unsustainable in the way it operates. The limitations of the linear economic model have been at the forefront to aspire circular economy in practice. Numerous factors have identified the need for the circular economy to emerg
The sustainable production and consumption of foods is gaining traction and globally, it is believed that there is nutritional transitional taking place from animal-based protein to plant-based protein. Product requirements, supply chain conditions, and consumption patterns for animal-based proteins and plant-based proteins will vary. This ensures that the packaging of plant-based foods must now m
Fossil-based resources for plastic production is growingly being challenged by renewable material in applications such as wood-plastic composites. One company dedicated to contribute to this transition is Bio Fiber Tech AB (BFT) who have patented a novel treatment of the wood component for improved compatibility with the polymer matrix. This thesis was in collaboration with BFT with the aim to cha
The most common controller in the process industry today is the PID controller due to its simple structure. A regular factory may have thousands of different PID controllers in use where each of them has to be tuned to work satisfactory. Doing this manually can become both a difficult and time consuming task where some knowledge for each process is required. Therefore, it is highly beneficial to h
The covid pandemic has put light on a trend of office buildings experiencing more vacancy than ever before, given our working habits have been forced to shift from occurring predominantly in an office to mainly being pursued from our private homes. This project foresees a future where working remotely has become the new normal and proposes a residential program in an existing office structure, giv
This thesis investigates the social dynamics of the Chin refugee group which currently faces great challenges in Malaysia, the host country. Modes of organisation and coping mechanisms are examined in relation to the specific legal and socio-political context. The theoretical concept of “diaspora” is used to make sense of processes of identity (re)construction and collective action. In addition, f
Long term economic growth leading to development is as much about growing as avoiding spells of considerable negative growth, or shrinking. However, much more attention has been given to understand what makes countries achieve high growth rates than to avoid shrinking. Here we explore empirically a novel approach which proposes that five interrelated dimensions of social capability (inclusion, tra
Introduction: This study evaluated lipid identification using mass spectrometry. Background: Three main modes of acquisition are used in mass spectrometry of lipids; data-independent acquisition (DIA), data-dependent acquisition (DDA) and targeted acquisition. DIA is the most including one, yielding a complete but complex data set, while targeted is the least including one, basing acquisition on
This report describes a systematic review regarding validations of calculations by measurements of isotopic compositions, or decay heat, on spent nuclear fuel, SNF. 15 relevant or otherwise interesting studies, were found. Two reports were chosen among the found studies and analyzed. One of the studies described validations made with experimental data from measurements of isotopic compositions on
The increase in contact resistance within battery systems remains poorly understood, despite being one of the primary contributors to battery degradation. This project aims to investigate this phenomenon by modeling the electrical interface as a contact between a pin and a busbar. The main goal is to build a DOE and machine learning framework, using Bayesian optimization to efficiently explore the
Stair width, riser height, tread depth and design may vary between different stairs. This study investigated how stairs with a variation of dimensions and designs affect people’s walking patterns, walking speed, and risk of falling. The thesis involved conducting observations and video recordings in six stairways with varying width, riser height, tread depth, and design, in addition to a brief lit
Betsockerprocessen är en energiintensiv process där ångdriven indunstning används för att avlägsna stora mängder vatten från den upprenade tunnsaften, som innehåller det från betorna extraherade sockret. I takt med industrins önskade fokus på energieffektivisering har membranteknologier för förkoncentrering av tunnsaften fått ett ökat intresse. Trots lovande resultat i ett begränsat antal försök åThe beet sugar process is an energy intensive process relying on steam evaporation to remove large amounts of water from the purified thin juice containing the sugar extracted from the beets. As the industry seeks greater energy efficiency, membrane technology for pre-concentration of thin juice has attracted interest. Limited trials have shown promise but fouling, sugar losses or high osmotic pre
This study investigates the corrosion behavior of a magnesium-zinc (Mg-Zn) alloy in a simulated body-like environment, with the aim of optimizing its degradation rate for biodegradable medical implant applications. These implants are designed to support bone healing and then gradually degrade once no longer needed, thereby eliminating the need for additional surgery. Magnesium alloys are promising
Research question: "How do young women construct and perform aspirational identities through the Clean Girl aesthetic on digital platforms?" Purpose: The purpose of this study is to expand the understanding of how trendy aesthetics on digital platforms like TikTok shape users’ identity construction and self-performance. Theoretical perspective: Two main theoretical fields, aspirational
Global food systems are increasingly vulnerable to climate change, energy volatility, and geopolitical disruptions—threatening the security and stability of perishable supply chains. This thesis investigates the potential of aseptic packaging technologies, specifically ultra-high-temperature (UHT) treatment and sterile filling, as a means to reduce energy consumption and enhance resilience in the
Buildings are responsible for approximately 30% of global energy use, with HVAC systems accounting for 40% of that demand. Among these, data centers have become significant energy consumers, requiring highly efficient and stable cooling solutions. This project aims to explore data-driven control methods to improve the energy efficiency of data center cooling systems as well as reduce the effort an
This study presents a custom surface electromyography (sEMG) data acquisition system combining the TI ADS1299 analog-to-digital converter, Teensy MicroMod micro-controller, and a Python-based graphical user interface for real-time signal monitoring and guided data collection. The system outperformed the widely used Ninapro dataset across all major classification metrics, demonstrating improved cla
Steam and water chemistry is fundamental for most power generation on indus trial scale. This includes the dosing of chemicals, the monitoring of both water and steam, as well as understanding the underlying causes to diagnose eventual problems. Öresundsverket, which was designed for seasonal operation, now has to perform multiple starts per year and in meeting these demands there is a possi bilit
Osteoarthritis is a multifactorial degenerative disease characterized by the breakdown of articular cartilage (AC), affecting hundreds of millions of people worldwide. Among many treatment options, hydrogels have emerged as promising candidates for cartilage replacement, due to their structural resemblance to the native tissue. Hydrogels can be made from various materials, and this study focuses o
