This work presents the design for a temperature drift-free path imbalanced ber interferometer for long-term laser frequency stabilization using coated bers with different thermal drift. For this purpose, single acrylate, dual acrylate, copper and aluminum coated bers are analyzed theoretically and experimentally regarding the thermal sensitivity of their optical path length. Experimental results w
Infrastruktursektorn är beroende av detaljerad information om markförhållanden för att säkerställa en miljömässig och socialt hållbar utveckling. Nuvarande hydrogeologiska metoder, såsom invasiv borrning, är ofta kostsamma, tidskrävande och begränsade i geografisk täckning av ett undersökningsområde. Direktströms resistivitet och tidsdomän-inducerad polarisering (DCIP) erbjuder ett icke-invasivt, The infrastructure sector relies on detailed subsurface data for environmentally and socially responsible development. Traditional hydrogeological methods, like invasive drilling, are costly, time-consuming, and limited in spatial coverage. Direct Current resistivity and time-domain Induced Polarization (DCIP) offer a non-invasive, cost-effective and spatially extensive alternative for estimating
The master’s thesis focuses on Gamified Green Information Systems (IS). It explores how gamified green IS influence employee behaviour and the motivational factors encouraging environmentally sustainable practices. For this, qualitative research was conducted, and data were collected through semi-structured interviews from seven employees. The data were analysed thematically to conclude to five th
This thesis addresses the need for robust price forecasting in the volatile Rare Earth Elements (REEs) markets. With a specific focus on neodymium, given it is the most utilized REEs, we investigate how feature selection can be effectively performed to guide REE price forecasting by proposing and evaluating three distinct methodologies: Adaptive Lasso, Post-Double Selection (PDS), and an integrate
This thesis explores how Employee-Driven Innovation (EDI) unfolds within Swedish municipal organizations and identifies how EDI is managed and structured, and what kind of innovations that are created in such organizational environments. While innovation is increasingly emphasized in the public sector, this study reveals that its practice is far from uniform. Through qualitative studies of three m
A gamma-charged particle coincidence spectroscopy setup was constructed, with the intended purpose of analysing future aerosol samples from the ESS. The setup consists of a Compex composite high purity germanium (HPGe) detector, with a bismuth-germanate oxide (BGO) anti-Compton shield (ACS), and a single-sided silicon strip detector (SSD). A 207Bi sample was used to evaluate the performance of the
Adeno-associated viruses (AAVs) are among the most promising vectors for safe and effective gene delivery in therapeutic applications. However, engineering functional AAV capsids remains a major challenge due to the vast sequence space, unpredictable biological performance, and limited translational success of many variants. Machine learning offers a powerful strategy to address these limitations
The increasing demand for electric vehicle charging stations creates new challenges for electric grid planning. This thesis proposes a framework for forecasting realistic 24-hour peak load profiles for new direct current fast-charging stations without historical observations. The method combines $K$-means clustering of existing stations’ hourly load patterns and random forest models that predict b
The Irish dairy industry has seen significant growth in recent times. It is also seen as one of key drivers in the Irish government’s plans to grow food and drink exports. However, there is an environmental cost to this. The niche dairy industry has been stagnant for years. This project looks at the potential for the niche dairy industry to grow and resulting in higher economic impact but lower en
Purpose: The purpose of this study was two-fold. First, we aimed to develop a framework concerning how to directly and indirectly control discrimination in the workplace using Man- agement Control Systems (MCS). Second, we wanted to examine whether this framework is practically applicable in multinational enterprises (MNE). Methodology: The first part of the purpose was achieved through conduc
This master thesis investigates the need for a new Permanent Establishment (PE) definition for digital purposes in Double Tax Treaties (DTTs). In the core of the necessity to pursue the analysis of this, are the digital economic developments, and the challenges that they pose for international tax law, policymakers, countries, and businesses. More specifically, the physical presence of digitalize
Research purpose: This study aims at finding out (1) how retailers' sales can be influenced if customers are offered to use SSTs (self-service technologies) for navigating themselves directly to the items they want to buy. (2) how the shopping experience can be influenced if customers are offered to use SSTs for navigating themselves directly to the items they want to buy. Methodology: Based o
Urbanisation is an inevitable part of globalisation. With the globalised food chain in place to feed the growing number of people living in urban areas. A remedy is often expressed to be urban farming, with local, sustainable production of food. This study presents a preliminary assessment of the dynamics between urban farms and residents in Malmö. Urban farms produce available food for the reside
Syftet med denna studie är att ge klarhet i adoptionsprocessen av en plattformsbaserad affärsstrategi för ett etablerat företag genom en fallstudie i den diskreta tillverkningsindustrin. Studien avser att bidra till den nuvarande begränsade litteraturen om affärsstrategiska och organisatoriska följder för etablerade företag när dessa implementerar en plattformsbaserad affärsstrategi. Därav är forsThe purpose with this thesis is to give clarity in the process when adopting a platform strategy for an incumbent by using a single case in the discrete manufacturing industry. Moreover, it seeks to extend the current yet limited research regarding strategical and organizational implications for incumbents when adopting a platform strategy. Therefore, the research question for this thesis is: Whic
Background: Globalization is a phenomenon which has been around since the mid- 19th century, influencing companies to either expand existing markets or entering new markets, to seek new profits. For companies with a global supply chain, the total supply chain cost is a vital factor. It is of high importance to reduce the costs in the supply chain, as lower costs will increase the profit. The case
A good head of beer gives nice texture and prevents releasing of aroma. The beer foam stability depends on numerous parameters. In this study, it was focused on the interfacial rheological properties such as surface tension and dilational modulus in relation the film formation by isohumulones and beer proteins at the air-water interfaces. The isohumulones and beer protein samples were prepared ind
Diabetes is an increasing problem in the world, where obesity is a large risk factor for developing the most common type of diabetes, i.e. type 2 diabetes. Numerous pharmaceuticals exist for managing the disease. The importance of the consumption of healthy foods is less emphasised albeit being an important and effective tool for managing the disease. The master thesis aimed at investigating how c
To catalyse transition toward a more sustainable economy, the European Union is proposing several policy interventions within the regulatory framework governing the financial sector. As part of this effort, a new EU Eco-label policy for green investment funds seeks to (i) facilitate individual investor participation in the sustainable investment market and (ii) increase private sector investments
