There are many species of leaves in nature. The complete leaves are easy for identification, while bitten leaves hinder the recognition of leaf species. In order to accurately recognize the species of injured and damaged leaves, firstly, a recognition system GUI (Graphical User Interface) was designed, then a cameras of iPhone 12 Pro Max was used t...

Mechanismen mit nachgiebigen Elementen haben aufgrund ihrer reduzierten Teilevielfalt und ihres geringeren Gewichts ein hohes Leichtbaupotenzial. Für ihre gezielte Synthese wurde in diesem Artikel die Phasenportrait-Methode vorgestellt [1], mit der große Verformungen mit ausreichender Genauigkeit vorhergesagt werden können. Die mathematische Behand...

When humans and AI-agents collaborate, they need to continuously learn about each other and the task. We propose a Team Design Pattern that utilizes adaptivity in the behavior of human and agent team partners, causing new Collaboration Patterns to emerge. Human-AI Co-Learning takes place when partners can formalize recognized patterns of collaborat...
