Slowing Sintering to Increase the Lifetime of Cu Nanoparticles on Metal Oxide Supports

The development of thermally stable nanoparticles is of utmost importance for applications like catalysis. In particular, Cu nanoparticles supported on metal oxides are easily deactivated under thermal treatments at low temperatures by sintering of the Cu nanoparticles. The formation of thermally stable nanoparticles is typically obtained with secondary drawbacks. In this study, an alternative met

There are plenty of atomic vacancies at the bottom

Atomic vacancies are primordial for controlling the photocatalytic activity of perovskites. On the one hand, they are useful adsorption sites and help narrow the band gap, but they may also trap the electron-hole pair created after light absorption. Its precise control, although essential, is hardly achieved with traditional methods. In this work, an alternative experimental approach is employed t

Att söka det sanna – le vrai

Denna uppsats närmar sig svenskt plein-air måleri i Fontainebleau och inom konstnärskolonin Grèz-sur-Loing från slutet av 1800-talet genom längtans lins. Med utgångspunkt i temat nostalgi och apodemialgi – längtan hem och längtan att bort – undersöks landskapsmåleriet och hur det visualiserar teman om natur och modernitet. Denna tid av exil är en viktig punkt i svensk konsthistoria eftersom den haThis thesis examines late 19th-century Swedish plein-air painting in Fontainebleau and within the artists’ colony Grèz-sur-Loing through the lens of longing. Drawing on the theme of nostalgia and apodemialgia—longing for home and the longing to leave—it investigates how landscape painting visualizes themes of nature and modernity. This time of exile is an important point in Swedish art history as

Att måla Fan i taket

In the late 17th century, a new style of decorations was developing in Sweden. Brutal flaming depictions of hell started covering the ceilings of the small parish churches. The trend would catch fire and over the course of the 18th century over 500 decorations were made in churches across western Sweden. This essay studies iconographic starting points for the style in the depictions the final judg

Enhancing Traffic Safety Through V2X-Based Deep Reinforcement Learning

As a core component of an ITS, CAVs have garnered significant attention and expect to play an important role in enhancing traffic safety. To enable (future) practical deployment of CAVs, safety strategies must be incorporated into the control design. This includes, in particular, strategies for ensuring avoidance or mitigation of multi-vehicle collisions. Conventional control strategies exhibit so

Safe reinforcement learning on the constraint manifold : theory and applications

Integrating learning-based techniques, especially reinforcement learning, into robotics is promising for solving complex problems in unstructured environments. Most of the existing approaches rely on training in carefully calibrated simulators before being deployed on real robots, often without real-world fine-tuning. While effective in controlled settings, this framework falls short in applicatio

A holistic concept on AI assistance for robot-supported reconnaissance and mitigation of acute radiation hazard situations

Hazardous situations involving radioactive, chemical, and other dangerous materials pose significant risks to emergency responders. In such situations, robots can support civil forces in reconnaissance and mitigation. However, this requires the development of robotic systems with novel AI-based assistance functions, operation procedures, and raises new ethical and legal questions. To address these

Bridging available as preprint version on arxiv: the gap between learning-to-plan, motion primitives and safe reinforcement learning

Trajectory planning under kinodynamic constraints is fundamental for advanced robotics applications that require dexterous, reactive, and rapid skills in complex environments. These constraints, which may represent task, safety, or actuator limitations, are essential for ensuring the proper functioning of robotic platforms and preventing unexpected behaviors. Recent advances in kinodynamic plannin

Turning rural knowledge into “nothing” or “something”

From the perspective of the Swedish education system, rural knowledge does not seem to be particularly important. Many young people in rural areas have deep and important knowledge that is invisible in school and during school time, both to teachers and to the young people themselves. This paper examines knowledge used in agriculture and animal husbandry, a type of knowledge that is particularly uFrom the perspective of the Swedish education system, rural knowledge does not seem to be particularly important.
