A temperature-robust level-set approach for eigenfrequency optimization

, 2023
The optimization of target eigenfrequencies is crucial for several engineering applications, including dynamical systems. Micro-electro-mechanical systems (MEMS) used in time-keeping applications, for example, require exceptional frequency stability ...

Assessment of the cartilage transplant thickness after removing of the tympanic membrane retraction pocket (finiteelement modelling)

Журнал Белорусского государственного университета: Математика, информатика, 2021
The retraction pocket emergence of the tympanic membrane (eardrum) leads to the sound conduction disorder of the middle ear. Surgical removal of fixed retraction pockets leads to perforations.

(Non)Resonance Bonds in Molecular Dynamics Simulations: A Case Study concerning C₆₀ Fullerenes

Entropy
In the case of certain chemical compounds, especially organic ones, electrons can be delocalized between different atoms within the molecule. These resulting bonds, known as resonance bonds, pose a challenge not only in theoretical descriptions of the ...

Bending Properties and Vibration Characteristics of Dowel-Laminated Timber Panels Made with Short Salvaged Timber Elements

Buildings, 2023
Salvaged timber elements often have length limitations, and therefore, their reuse in structural products normally would require additional processing and end-to-end joining.

Eigenfrequency loci crossings, veerings and mode splittings of two cantilevers coupled by an overhang

, 2020
Eigenfrequency loci veering, which indicates strong mode coupling and sometimes mode localization, is a much sought-after property in the applications of mass sensing and opto/electromechanics.
