Damage Detection in Double Layer Grids with Modal Strain Energy Method and Dempster-Shafer Theory [PDF]
Civil Engineering Infrastructures Journal, 2021 Change in modal strain energy is one of the indicators used to detect damage in structures. However, in structures with high degrees of freedom, such as double-layer grids, this method requires a relatively large number of mode shapes which in practice ...

Length of Mode Shapes in Numerical and Experimental Models
, 2022 A new concept of length of a continuous mode shape has been recently defined by the authors, which depends on the mode shape and how the volume is distributed in the structure. This concept was then extended to discrete systems by introducing the concept

Fundamental Modes of Swimming Correspond to Fundamental Modes of Shape: Engineering I‐, U‐, and S‐Shaped Swimmers [PDF]
Advanced Intelligent Systems, 2021 Hydrogels have received increased attention due to their biocompatible material properties, adjustable porosity, ease of functionalization, tuneable shape, and Young's moduli. Initial work has recognized the potential that conferring out‐of‐equilibrium properties to these on the microscale holds and envisions a broad range of biomedical applications ...

How Modes Shape Casimir Physics
International Journal of Modern Physics A, 2022 Modes have steadily influenced the understanding of physical systems through time. At least since the prediction of the Casimir effect, they also play a very important role in Casimir physics and in the understanding of the different phenomena typical of this research field.
