Social Metadata for Libraries, Archives and Museums. Part 3: Recommendations and Readings
No full textRecommendations on social metadata features most relevant to libraries, archives, and museums and an annotated reading list of the literature the research group consulted during our research. We believe it is riskier to do nothing and become irrelevant to our user communities than to start using social media features

Design and Analysis of Yoshimura Tubular Origami Mechanisms
No full textThe Yoshimura tubular origami mechanism possesses numerous advantageous properties and, when integrated with advanced material technologies, can be applied across various engineering disciplines. However, current research on Yoshimura origami predominantly focuses on centrally symmetric tubular origami mechanisms, which restricts the structural forms and motion patterns of these mechanisms. Drawing inspiration from the biological concept of “morphological variation,” we propose a novel tubular origami mechanism based on the Yoshimura pattern, which is the main contribution of this research. We analyze the Yoshimura planar crease elements and introduce both heterocellular and homocellular tubular origami mechanisms. Furthermore, we establish the origami topology matrices for the Yoshimura tubular origami mechanisms. This research also investigates complex motion forms that differ from traditional Yoshimura origami mechanisms, including macroscopic twisting and compound movements, thereby providing an intuitive design approach and extensive structural guidance for research in Yoshimura tubular origami engineering. Based on the tubular origami mechanism, we created an origami robot and investigate its motion characteristics

Golden Ratio Yoshimura for Meta-Stable and Massively Reconfigurable Deployment
No full textYoshimura origami is a classical folding pattern that has inspired many deployable structure designs. Its applications span from space exploration, kinetic architectures, and soft robots to even everyday household items. However, despite its wide usage, Yoshimura has been fixated on a set of design constraints to ensure its flat-foldability. Through extensive kinematic analysis and prototype tests, this study presents a new Yoshimura that intentionally defies these constraints. Remarkably, one can impart a unique meta-stability by using the Golden Ratio angle to define the triangular facets of a generalized Yoshimura. As a result, when its facets are strategically popped out, a ``Golden Ratio Yoshimura\u27\u27 boom with modules can be theoretically reconfigured into geometrically unique and load-bearing shapes. This result not only challenges the existing design norms but also opens up a new avenue to create deployable and versatile structural systems

New Approach to Folding a Thin-Walled Yoshimura Patterned Cylinder
No full textA new approach for folding the Yoshimura cylinder is proposed in this study. The proposed concept is based on a reconfiguration process involving a cylindrical structure with the Yoshimura pattern and the bellows fold pattern. Static analyses are conducted to confirm the effectiveness of the proposed folding methodology. A special case of folding is observed that does not create wrinkles in the fully folded state. A mathematical problem is established and three governing equations are derived from the problem. The special folding pattern is determined by solving the three governing equations. The most geometrically and structurally efficient configuration for the reconfigured cylinder is determined. A geometrical analysis is conducted for various configurations of the cylinder that can be observed in the proposed folding methodology. The proposed folding methodology folds the Yoshimura cylinder much more efficiently in terms of required force and stress compared to the conventional folding approach.
