This project investigates non-planar 3D printing techniques using a robotic system and Polylactic Acid (PLA) filament, drawing inspiration from the spider web’s structure. The primary aim is to develop methods that optimise material usage while maximising print coverage over large areas. Ultimately, the research seeks to expand the capabilities of robotic manufacturing and uncover new architectura
The global shift in the food system towards more sustainable diets has made legumes such as chickpeas, lentils and beans increasingly important due to their nutritional and environmental benefits. But despite these benefits that they offer, their consumption remains relatively low. A key reason for this, is the digestive discomfort they cause such as bloating and flatulence alongside reduced miner
The increase in global competitiveness and the advancement of digital technology are compelling organizations to innovate by enhancing their product offerings with digital services. Although this phenomenon known as digital servitization is well researched in larger organizations, there is less investigation on how small and medium enterprises (SMEs) manage this trend, particularly in Sweden. This
In this work, we present the design, fabrication, and characterization of InAs-based nanowire heterostructures with epitaxially defined InP and GaAs potential barrier segments, aimed at understanding and demonstrating the functionality of a double-barrier nanowire heterostructure as a hot-carrier photovoltaic, in which InP and GaAs barriers encapsulate an InAs absorber region, where hot carriers a
This masters thesis handles segmentation of blood vessels in Wistor-rat lungs, scanned by a µm-CT scanner. These scans are very detailed 3D-volumes and have been rescaled to a more manageable size of 1024 × 1024 × 1024 voxels per volume. The main goals of the thesis is to find a more efficient way to perform segmentation in medical images and thus semi-supervised segmentation techniques have been
Från industriella restprodukter till grönt drivmedel – två vägar mot förnybara bränslen. Bio-olja från skogsrester kräver uppgradering för att kunna behandlas i befintliga oljeraffinaderier. Två innovativa processer visar potential, men tekniska och ekonomiska utmaningar framstår. Att minska beroendet av fossila bränslen är avgörande för att nå klimatmålen. Ett lovande alternativ är att producerThis master’s thesis evaluates the commercial-scale feasibility of two processes that upgrade lignocellulosic bio-oil: dewatering and derivatization upgrading (DDU) and green cooking and cleaning (GCC). Both processes aim to produce upgraded bio-oil suitable for co-processing in existing oil refineries, though they differ significantly in complexity. GCC includes the entire conversion from raw bio
Titel: Strategisk diversifiering av värdeerbjudanden i T-KIBS Författare: Daniel Danielsson och Theo Lönnebacke Handledare: Ola Alexanderson Bakgrund: Teknologibaserade kunskapsintensiva tjänsteföretag (T-KIBS) bedriver ofta projektbaserade affärer där teknisk expertis står i centrum. Inom dessa relationer finns en växande medvetenhet om potentialen att skapa ytterligare kundvärde genom komplet
Potentialen av tillräcklighet för hållbar proteinkonsumtion Det går att leva ett rikt liv och samtidigt bidra till sänkta växthusgasutsläpp. Genom att fokusera på tillräcklighet kan grundläggande behov uppfyllas samtidigt som tid, energi och pengar kan läggas på sådant som får en att må bra. Vanligen associeras principer om tillräcklighet med minskad materiell konsumtion, men det går också att tilOne measure required to reduce greenhouse gas emissions is changed consumption behaviours in affluent contexts. This might be motivated by sufficiency, and while the concept is often related to reduced material consumption, its practical implications regarding food consumption have not been explored to the same extent. To investigate how the literature on sufficient consumption may offer new insig
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 contributes to ongoing debates on alternative models of refugee integration through a case study of Community-based Integration (CbI). As a participatory approach, CbI centers on social inclusion and community cohesion, expanding equitable access to opportunities for both refugees and locals. It has shown particular relevance in small towns and semi-rural areas affected by depopulation
Entanglement in quantum mechanics manifests in two distinct forms, either between many qubit systems or two high-dimensional quantum systems with entangled degrees of freedom. These two classifications are well established. However, recent strides have been made to unify these two conditions as quantum technologies evolve further. The GME-dimension quantifies the entangled degrees of freedom in a
Augmented reality (AR) is increasingly being adopted in fashion retail to enhance customer ex-perience, boost engagement, and reduce uncertainty in online shopping environments. While AR offers both hedonic and utilitarian value, its implementation across large multinational fashion companies remains inconsistent due to financial, technological, and organizational barriers. This study investigates
Nakhliter är kumulatbergarter som är rika på klinopyroxen och bildades från basaltisk magma för cirka 1,3 miljarder år sedan. De uppvisar vanligtvis tecken på vattenhaltig omvandling. Denna studie fokuserar på omfattningen och ursprunget av den vattenhaltiga omvandling i nakhlitiska marsmeteoriten Northwest Africa (NWA) 11013. Studien behandlar fyra centrala frågeställningar: omvandlingstypen, desNakhlites, which are clinopyroxene-rich cumulate rocks formed from basaltic magma around 1.3 billion years ago, frequently exhibit evidence of aqueous alteration. This study focuses on the extent and origin of aqueous alteration in the nakhlite Martian meteorite Northwest Africa (NWA) 11013, addressing four key research questions: the specific type of alteration, its connection to microstructures,
This master’s thesis explores Recommender Systems (RS) and how these can promote sustainable consumption on e-commerce platforms by influencing consumer behaviour toward environmentally responsible choices. The aim is to provide design recommendations for sustainability-aware RS that align user preferences and environmental goals. Two research questions guided the study: how RS are designed to enc
For 75 years, the United Nations has focused on peacebuilding, with peacekeeping operations serving as the organization's most visible and significant representation. These operations are regarded as one of the most effective methods for helping a nation transition from conflict to peace. The peacekeeping operation has predominantly occurred in the Global South, where it has faced significant
