Extrusion-based 4D-printing, which is an emerging field within additive manufacturing, has enabled the technical transfer of bioinspired self-shaping mechanisms by emulating the functional morphology of motile plant structures (e.g., leaves, petals, caps
(Portland cement, calcium aluminate cement, gypsum) were elaborated. This study investigates the impact of TA, CE, and PCE on the fluidity, fluidity loss, flexural strength, and compressive strength of cement-based self-leveling mortar. An orthogonal test design is employed to explore the ...
extrapolate an error function and ensure equivalency between the printed and digital images. This may involve testing a protocol based solely on the printed PUF labels. The use of geometric distortion-invariant image hashing schemes can be employed for better authentication of digital images [45]. ...
