I den moderna kemiska industrin är effektivt energiutnyttjande avgörande för ekonomisk bärkraft och miljömässig hållbarhet. Värme- och energiintegrering har en avgörande roll i att optimera kemiska processer och kan minimera energislöseri samt minska bränsleförbrukningen och utsläppen av växthusgaser. Detta genom att strategiskt återanvända värme och energi som frigörs i andra delar av processen. In the modern chemical industry heat and energy integration is crucial for optimizing process efficiency and increasing economic viability and environmental sustainability. By strategically recovering and reusing heat and energy within the plant, industries can significantly decrease their reliance on external energy sources, leading to costs saving and a smaller carbon footprint. One of the late

This disquisition explores the possibilities to install a battery storage situated in a gasturbineplant to enable a start up of the gasturbine in the case of a powerfailure. Since powerfailures are rare, the battery will mostly and to a large extent be unused, this creates an economic dilemma. Uniper has taken in and recieved a tender which includes and discribes a battery with a larger storage sy

Head-mounted mixed reality devices are making their way into airline pilot training. Devices that use passthrough video hold much promise but come with caveats. Because current generation passthrough video devices occlude natural light, users rely entirely on a digital video feed that lacks the visual fidelity and field of view of the unaided human eye. The application of head-mounted extended rea

Organizational Commitment (OC), which describes an individual’s psychological attachment to an organization, is a central component in organizational behavior research. This study examines the impact of perceived organizational values, personal values, organizational support, positive leadership, and job autonomy on OC and its three components: affective, normative, and continuance commitment. Dra

This thesis explores the effect on neonatal, post-neonatal, and child mortality of being a motherless child and the interaction this situation had with socio-economic status and gender in Sweden during the period 1790-1910. Using a longitudinal, individual level, database (SwedPop), covering large parts of the Swedish population, together with a Cox proportional hazards model, this study finds tha

This study explores the use of Large Language Models (LLMs) to automate sustainability reporting in accordance with the European Sustainability Reporting Standards (ESRS). Given the increasing complexity and regulatory demands of sustainability reporting, organizations face significant challenges connected to their reporting processes. To evaluate the potential of LLMs in addressing these challeng

This thesis examines customer satisfaction within IKEA's support services in Sweden and Great Britain by analyzing customer feedback data. It explores the intersection of anthropology and computational social science, contributing to the growing field of computational anthropology. The study identifies recurring themes in customer comments by employing a mixed-methods approach that combines co

Due to higher demands on the electrical systems in the aviation industry, the generation and distribution of electrical power, in aircrafts, needs to be researched and developed further. Key requirements include increased power capacity to meet future demands, a transition from AC to DC supply and an increased voltage level. For power generation, a generator is coupled to the jet turbine which mus

Att kunna skräddarsy biologiskt nedbrytbara stärkelsepartiklar för användning i medicintekniska produkter låter kanske som science fiction, men det håller snabbt på att bli verklighet! Dessa mikroskopiska partiklar tillverkar man av något som de flesta har hemma, potatisstärkelse och kan användas i medicintekniska produkter för att exempelvis blockera blodflödet till tumörer eller upptäcka läckageDegradable starch microspheres (DSMs) are promising biomaterials with expanding medical applications due to their biocompatibility and controlled degradation. DSMs are produced by forming a water-in-oil emulsion using a starch solution, an emulsifier e.g. Starch Acetate Butyrate (SAB) and toluene, followed by crosslinking using a crosslinker, e.g. epichlorohydrin (ECH). The relationship between re

In today’s increasingly digital world, cybersecurity challenges extend far beyond the organizational perimeter, affecting both professional and personal domains. While organizations invest in comprehensive cybersecurity policies to mitigate risks, less is known about how these policies influence employees’ personal cybersecurity outside the workplace. This study investigates that relationship thro

Bygg- och fastighetssektorn står för över 20 procent av Sveriges växthusgasutsläpp, vilket gör den till en central aktör i omställningen till ett hållbart samhälle. För att uppnå klimatmål och underlätta cirkulärt byggande krävs effektiva och spårbara miljödataflöden genom hela byggprocessen. Projekteringsfasen erbjuder särskilt goda möjligheter att påverka dessa flöden, tack vare digitaliseringenThe construction and real estate sector accounts for over 20 percent of Sweden’s greenhouse gas emissions, making it a key sector in the transition toward a sustainable society. To achieve climate targets and enable circular construction, efficient and traceable environmental data flows are required throughout the entire building process. The design phase, in particular, offers significant opportu

This thesis explores a classically conformal extension of the Standard Model featuring a real scalar singlet field as a Dark Matter candidate. In this framework, electroweak symmetry breaking arises radiatively via the Coleman-Weinberg mechanism, foregoing explicit mass scales and preserving classical scale invariance at tree level. The singlet scalar, stabilized by an imposed Z2 symmetry, is inve

Amid a global housing crisis that leaves more than 1.6 billion people inadequately housed, dominant legal and policy frameworks still define “adequate housing” largely in terms of fixed outcomes such as tenure security, affordability, and habitability. This thesis argues that these lists overlook a critical dimension: people’s housing agency, the real freedom to shape their housing situation. Grou

Music’s diverse psychological roles include possible cognitive enhancement, however, results are either insufficient or mixed based on already existing literature. The current interventional study observed the influence of musical stimuli on time perception and sustained attention possibly explained by altered states of consciousness. 30 participants were assigned equally to two different musical

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

Forskningsfrågor Hur beskriver de anställda företagets identitet? (och) Hur upplever de anställda att verksamheten styrs? Syfte Syftet är att bidra till förståelsen av identitet som styrning. Mer precist, hur identitetsreglering sker dynamiskt med inflytande av både medarbetare och chefer. Metod Studien baseras på sju semistrukturerade, kvalitativa intervjuer med anställda från ett litet nordiskResearch question How do the employees describe the company’s identity? (and) How do they perceive the way it is controlled? Purpose of study The purpose is to contribute to the understanding of identity as a form of control. More specifically, how identity regulation occurs dynamically through the influence of both employees and managers. Methodology The study is based on seven semi-structured,

This thesis explores the positioning of internal crisis communication in relation to external communication, specifically within the context of governmental crisis response. Guided by the case of the Lebanon crisis in 2024, this study investigates how crisis experts from a European Ministry of Foreign Affairs interpret internal communication across the three phases of crises, drawing on the Rhetor
