production for its food supply. Vegetable seed production is much different and more challenging than production of grain crops. This book explains the biology and technology behind producing, maintaining, and enhancing the quality of vegetable seeds from breeding through to the marketed product. It begins with six chapters on a broad range of seed-related topics: the importance of seeds, reproductive biology of plants, genetic improvement strategies, quality assurance of seed production, post-harvest seed enhancement, and organic production. The remaining chapters cover seed production in eleven important vegetable families. Each chapter provides a description of the botany, types and cultivars, genetic improvement, pollination, soil fertility management, pest management, crop production, harvesting, post-harvest handling, and seed yields. The aim of this book is to educate how to produce high-quality vegetable seeds. Incorporating both current methodologies and recent research results, it is suitable for students, researchers, and professionals in the seed industry.Proceedings of the 10th Hydrogen Technology Convention, Volume 2: WHTC 2023, 22–26 May, Foshan, China (Springer Proceedings in Physics #394)

Dabei wird ein…
modellbasierter, kaskadierter Querdynamikregler um ein künstliches neuronales Netzwerk (KNN) erweitert. Das KNN wird ohne „Vorwissen“ implementiert und aktiv im geschlossenen Regelkreis trainiert. Die Untersuchungen werden dabei sowohl in Simulationen, als auch in einem realen Versuchsträger durchgeführt. Die Versuche zeigen das Leistungsvermögen des hybriden Regelungskonzeptes. Bei geringer Fahrzeugdynamik ist eine präzise Fahrzeugführung auch ohne KNN möglich. Bei hoher Dynamik resultieren jedoch Abweichungen vom Sollkurs, die durch das iterativ lernende Netzwerk schrittweise reduziert werden. Durch die situationsabhängige Optimierung der Netzwerkgewichte wird der Einfluss des systematischen Fehlers des zu Grunde liegenden Modells kompensiert und die Regelgüte verbessert. Dieses Verhalten kann durch geeignete Auswahl der Designparameter des KNN für jedes der betrachteten Szenarien aufgezeigt werden. Die Anpassung der Netzwerkgewichte ermöglicht sowohl im Fehlerfall als auch bei hoher Fahrzeugdynamik und ungenauer Systemidentifikation eine Verbesserung der Regelgüte im Vergleich zum rein modellbasierten Basisregler.ETHICS: Cross-disciplinary Strategies (Designing Environments)

This book outlines, within the Italian national framework, the current and potential paths oriented towards a new concept of Architectural…
Heritage, through actions referring to Innovation and Experimentation and Protection and Transformation of the Architectural Heritage. The development of the themes is articulated in two sessions dealing with the aspects related to the analysis and mapping of Architectural Heritage to face the context of the current Climate Crisis and the development of projects and experimentations oriented to the Green and Digital Transition. The evolution of the concept of Heritage, as conceived by the United Nations 2030 Agenda and in the Green Deal and New European Bauhaus, aimed at constructing an inclusive and universally recognised definition to support supranational objectives of sustainable human development, gives rise to innovative strategies, methodologies and technologies that—in a direction of mitigation, contrast and adaptation to climate change—allow for the safeguard, renewed management and a hope for valorisation of Heritage on a national scale. In this direction, the understanding of Architectural Heritage as a 'non-renewable resource' determines the need to activate design experimentation laboratories oriented towards regeneration, articulated and complex, which require, in order to respond to the challenges posed by our era, a sensitive and dialogic multidisciplinary vision of a holistic type. In fact, on the one hand, it is necessary to redefine the usability and management methods of built heritage through the adoption of digital, mobility, energy, ecological, social, green and blue infrastructures; on the other hand, it is necessary to introduce new qualitative and quantitative parameters and performance indicators, adequate to verify the validity of the implemented strategies in a perspective of adaptation to climate change, able to clarify contents, processes and tools to contrast future risks. The pursuit of these objectives refers to the innovation of training paths, professionalising procedures, administrative regulations, and public policies that involve citizens and the private partnership towards a different project qualification and empowerment of stakeholders, inhabitants, professionals, and clients. The Technological Project makes it possible to activate different interventions aimed at acting, in an integrated manner, on assets, context and communities, according to an approach that reinterprets them on a common score, as proposed by the European Next Generation programme in three priority aspects: digitalisation and innovation, environmental transition, increased resilience and social sustainability of national economies. In this scenario, the interventions aimed at outlining sustainable development actions will have to place these concepts at the centre in a harmonious vision that starts from the recognition and enhancement of the Architectural Heritage, recognising it as a fundamental asset of the territories.Conversion of Water and CO2 to Fuels using Solar Energy: Science, Technology and Materials
