Diffusion Models have achieved state-of-the-art results in image generating tasks, yet face different challenges when used in different domains. We first give a brief overview of the Diffusion Models architecture. Then, we present a new model and architecture called SVGFusion that applies the principles of Diffusion Models to generate Vector Graphics. Vector Graphics have a complex structure and are vastly different than pixel images, and thus the main challenge when working with Vector Graphics is how to represent their complex structure in a way that a Diffusion Model can effectively process. We will explain this and the further challenges that we encountered during the process and how we successfully addressed some of them. We demonstrate the effectiveness of our approach by training a sample model on a decently sized dataset as well as running valuable experiments. Furthermore, we offer useful insights, recommendations and code to researchers who wish to further explore this topic.

This thesis focuses on the magneto-elastic interactions in thin films and their significance in technological applications with particular focus on sensors. The magnetostriction, constant which determines the strength of these interactions, plays a crucial role in various applications. For instance, strain immunity is essential for magnetic sensors to reduce strain cross-sensitivity, particularly in the case of flexible substrates. On the other hand, to sense strain mate- rials require giant strain effects. The optimization of the magnetic sensing layer, including strain anisotropy, is crucial for magnetic sensors performance, depending on their specific application requirements. The first part of this thesis discusses the characterization and the engineering of the strain-dependent material properties for the development of the free layer of magnetic sensors. The focus is on two material platforms: a Ni/Fe multilayer and Permalloy. The use of He+ ion irradiation as a post-deposition technique is explored to control magnetostriction and enhance magnetic softness. The strain dependence of anisotropy and magnetization compensation is explored in another material platform, Co/Gd synthetic ferrimagnets, that has the unique ability to switch their magnetic state using a laser pulse. In the second part of this thesis, the control of domain walls using strain is extensively studied for their applications in memory devices and magnetic sensors. Domain walls offer non-volatile positioning and energy efficiency in various applications. However, the influence of mechanical strain or stress on these sensing components has been overlooked. In our studies, we highlight the importance of considering mechanical strain in actual devices, exploring the effects of different types of strain on a sensor-type device. Uniform strain and its compensation through material preparation are discussed, along with the conceptualization and realization of a new magnetic sensor based on spatially variant strain. Furthermore, the impact of ...

Hydrologically induced disasters resulting from both water scarcity and excess, pose a threat to mountain communities and developmental infrastructures in the Himalayas. Over the last decade, the HILLTOP, a network of hydrological observatories in the Himalayan region has gathered data which improves our understanding of diverse water pathways in the region. The talk traverses through two water pathways - mountain aquifers, and high gradient rivers - presenting the latest empirical evidence emerging from pilot field studies towards mitigating hydrologically induced disasters.The first section focuses on the increasing drying up of springs, the lifeline of hill communities. Recent analysis emerging from stable isotope and hydrochemistry studies in select pilot springsheds are presented. When detailed studies are not available, as is the case in many parts of the Himalayas, systems thinking approach helps direct targeted interventions. So, we also present vulnerability assessment using a systems thinking approach as a tool for targeted interventions for spring rejuvenation projects. In the second section, a case of field observations of bedload in two headwater rivers is presented. The study highlights the challenge in arriving at accurate estimates of rainfall triggered mass movement of sediments, and presents recent attempts are better understanding of the empirical equations used to estimate bedload under high flow conditions. These studies underscore both the need and challenges in compiling evidence through field observations in Hydrology that improve our understanding of hydrologically induced disasters. Innovative observatories we hope will inform policy and action towards sustainable development of our mountains landscapes. The 28th IUGG General Assembly (IUGG2023) (Berlin 2023)

The possibility of electric vehicles to technically replace internal combustion engine vehicles and to deliver economic benefits mainly depends on the battery and the charging infrastructure as well as on annual mileage (utilizing the lower variable costs of electric vehicles). Current studies on electric vehicles’ total cost of ownership often neglect two important factors that influence the investment decision and operational costs: firstly, the trade-off between battery and charging capacity; secondly the uncertainty in energy consumption. This paper proposes a two-stage stochastic program that minimizes the total cost of ownership of a commercial electric vehicle under uncertain energy consumption and available charging times induced by mobility patterns and outside temperature. The optimization program is solved by sample average approximation based on mobility and temperature scenarios. A hidden Markov model is introduced to predict mobility demand scenarios. Three scenario reduction heuristics are applied to reduce computational effort while keeping a high-quality approximation. The proposed framework is tested in a case study of the home nursing service. The results show the large influence of the uncertain mobility patterns on the optimal solution. In the case study, the total cost of ownership can be reduced by up to 3.9% by including the trade-off between battery and charging capacity. The introduction of variable energy prices can lower energy costs by 31.6% but does not influence the investment decision in this case study. Overall, this study provides valuable insights for real applications to determine the techno-economic optimal electric vehicle and charging infrastructure configuration.

The purpose of this document is to develop a concept for action plans within the framework of SALUTE4CE project, specifically, for urban pilot project areas where urban environmental acupuncture is being applied and their respective Functional Urban Areas (FUAs). The action plan concept incorporates the methodology for selecting urban environmental acupuncture (UEA) sites and this includes the typology and selection of interventions created within the SALUTE4CE project. The transnational action plan concept is comprised of three main sections: general considerations, creating local action plans and plan implementation.

EDEN ISS is a European project focused on advancing bio-regenerative life support systems, in particular plant cultivation in space. A mobile test facility was designed and built between March 2015 and October 2017. The facility incorporates a Service Section which houses several subsystems necessary for plant cultivation and the Future Exploration Greenhouse. The latter is built similar to a future space greenhouse and provides a fully controlled environment for plant cultivation. The facility was setup in Antarctica in January 2018 and successfully operated between February and November of the same year. During that nine month period around 270 kg of food was produced by the crops cultivation in the greenhouse. It is the wish and more often the need for scientific projects to communicate their outcomes not only to the scientific community, but also to the general public. The EDEN ISS project and in particular the experimental phase in Antarctica was accompanied by extensive public outreach activities. Presence in social media, a project website, informative flyers, an experimental toolkit for young students were created in order to engage with the general public. This paper describes the different public outreach activities of the project and also evaluates their effectiveness. For the evaluation, statistics from the website and social media accounts as well as responses to press releases and educational activities are being displayed. Based on the experience from the outreach campaign of EDEN ISS, the paper provides recommendations on how to organize and conduct public outreach activities for scientific projects in space exploration

Micro-structural evolution during the annealing of cold rolled Mg, Mg-1.5 normal direction and Mg-3Y sheets has been examined. The experimental results show a significant difference in recrystallization kinetics and grain growth between pure Mg and Mg-rare-earth alloy sheets. Pure Mg sheet shows rapid recrystallization and grain growth, whereas recrystallization is considerably retarded in the Mg-rare-earth alloys. Although recrystallized grains which are triggered at shear bands in the cold rolled pure Mg sheet show a relatively weak texture with a basal pole split into the sheet rolling direction, rapid grain growth is accompanied by re-strengthening of the basal-type texture. In contrast, a weak texture appears in the early recrystallization stage in Mg-rare-earth alloys and is retained during annealing due to retarded recrystallization and grain growth.
