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

The present thesis analyses the political and cultural ideas, as well as the narrative, articulated in the mid of the 19th century by prominent members of the student movement actively engaged in the pan-nationalistic, ideological current of scandinavianism. The research’s empirical material that conveys the narrative and idéas of the student movement was written and published in the early 1840s b

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

This thesis examines how autonomous buses are interpreted and evaluated as a potential mobility solution within a multi-level planning context involving both municipal and regional perspectives. While autonomous vehicles are often framed as a key component of future sustainable transport systems, their implementation depends not only on technological development but also on social acceptance, inst

This thesis explores various aspects of urban design and societal factors that contribute to creating child-friendly environments. The study begins by examining child-friendly design, emphasizing the significance of considering children’s needs in urban planning. Following this, a city-wide analysis of Reykjavík is conducted, exploring the swimming pool culture, the preschool and school system, an

Forensic sexual assault samples typically contain a mixture of a small quantity of sperm cells and a high quantity of epithelial cells. This relationship complicates the generation of a DNA profile, which prompts the need for differential lysis and extraction of the DNA. Differential extraction is a lengthy method that includes multiple tube transfers and requires a purification step. Amicon Ultra

The building sector contributes to one-fifth of Sweden’s total greenhouse gas emissions (GHG) and consumes 40 % of the final energy consumption. To achieve the climate goals set by the Swedish government, the building sector requires rapid development to reduce its climate impact. The climate impact of buildings comes from two types of energy throughout the building's lifecycle: operational an

Background: Purchasing and Supplier Relationship Management are becoming increasingly important as companies’ competitiveness increases. One part of this is Supplier Performance Evaluation (SPE), which is part of the final step in the purchasing process and can be performed in many different ways. SPE can ensure that suppliers are performing as expected and when not, actions can be taken. When mea

Computer vision is on the cusp of revolutionizing several different markets through its applications. One such market is that of fitness and exercise. Advagym, Sony's connected gym solution is currently employing IoT solutions to track exercises in a gym environment. Together with Sony's R\&D Center Lund Laboratory's computer vision- and machine learning-equipped tracking system -

This thesis studied methods of improving a background model for a data processing pipeline of LiDAR point clouds. For this, two main approaches were evaluated. The first was to implement and compare three different models for detecting ground in a point cloud. These were based on more classical modeling approaches. The second was to use Deep Learning for semantic segmentation of point clouds and t

The EU-US Privacy Shield Decision on data transfers between the EU and the US was found invalid by the CJEU Schrems II ruling on 16 July 2020. After Schrems II, discussions among scholars and practitioners on legal challenges of international data transfers resulting from the case has gained much tension during the past years. Given the significant amount of data that flows between organizations a

The rehabilitation techniques currently available for patients who suffer from injury to the ulnar or median nerve tends to give suboptimal results. Typically, adults who are operated due to a complete transection of the median or ulnar nerve never regain normal sensibility in the injured hand leading to severe limitations in terms of hand function. One of the biggest challenges in sensory rehabil

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
