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

The manufacturing of hardware is a complex process where many different types of parties are involved. This creates risks of inserting hidden harmful parts, so called Hardware Trojans (HTs). HTs can have many different functions, such as reducing security, leaking information or degrading a system. This thesis examines how Ring Oscillators (ROs) can be exploited by a malicious party and modified t

Denna uppsats utforskar kommodifiering av jaget på TikTok utifrån Zygmunt Baumans och Hartmut Rosas teorier om kommodifiering respektive förfogbarhet. Båda teorierna fokuserar på modernitetens förhållande till individen och hennes sätt att förhålla sig till världen. Fokus på samhällets strukturella uppbyggnad och dess påverkan på individen är även grundläggande inom både teorier. TikTok är en plat

Fastighetstaxeringen utgör en central del av det svenska skattesystemet och syftar till att fastställa det taxeringsvärde som ligger till grund för fastighetsskatt och kommunal fastighetsavgift. Även om lagstiftningen huvudsakligen är värderingsteknisk till sin karaktär, innehåller den bestämmelser om indelning i olika byggnadstyper – något som har direkt betydelse för om och hur en fastighet beskProperty taxation is a key component of the Swedish tax system, serving to determine the assessed value used for levying property tax and the municipal property fee. Although the legislation is primarily valuation-oriented, it also includes provisions on the classification of building types, an element that directly affects whether and how a property is taxed. Buildings classified as "special

Unhealthy Body Mass Index (BMI) levels at both ends of the weight spectrum remain a public health concern despite widespread interventions. This ongoing problem points to the importance of understanding the factors that shape BMI beyond behavior and lifestyle alone. The present study therefore investigated the genetic influences on BMI and the predictive roles of intelligence and personality in sh

The race towards sustainability In a rapidly advancing society, energy consumption has increased in tandem with the rise of digitalisation and modern lifestyles. However, the recent situation of producing energy is to use finite resources such as fossil fuels. Furthermore, the use of said resource has side effects that are highly undesirable, as it is a huge contributor towards global warming. Alt
