Behavioral Modeling of Memristors under Harmonic Excitation [PDF]
Micromachines, 2023 Memristors are devices built on the basis of fourth passive electrical elements in nanosystems. Because of the multitude of technologies used for memristor implementation, it is not always possible to obtain analytical models of memristors.

Analysis of scaffolding harmonic excitation [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2023 Scaffolding is equipment usually used at construction sites. A scaffolding structure is lightweight and made of elements used many times. The characteristics of scaffolding make it susceptible to dynamic actions present at the structure or occurring ...

Vibration responses characteristics of a Ginkgo biloba tree excited under harmonic excitation. [PDF]
PLoS One, 2021 The most effective method of the fruit harvesting is the mechanical harvest. The frequency spectrum of different testing positions on a Ginkgo biloba tree under the impact excitation was tested in the laboratory. The acceleration responses under the harmonic excitation were measured at the frequency of the peak and trough points in the frequency ...

Lieb's soliton-like excitations in harmonic trap [PDF]
EPL (Europhysics Letters), 2013 We study the solitonic Lieb II branch of excitations in one-dimensional Bose-gas in homogeneous and trapped geometry. Using Bethe-ansatz Lieb's equations we calculate the "effective number of atoms" and the "effective mass" of the excitation.

An harmonic equivalent excitation method for random vibration response
Advances in Mechanical Engineering, 2022 Many loads on engineering structures had obvious randomness, such as earthquakes, wind, sea waves, uneven pavement, etc. The calculation and analysis of random vibration were complicated and inefficient, which has perplexed the development of engineering
