Dynamic soil-pile-interaction effects on eigenfrequency and damping of slender structures [PDF]
, 2014 Single pile foundations have been widely used as a support solution for offshore wind turbines (OWT), where the design has been driven towards large diameter monopiles in order to satisfy the deformation limitations in the superstructure.

Laser &Photonics Reviews, Volume 20, Issue 12, 18 June 2026.This work introduces two types of bound states in the continuum (BICs) and their merging in a waveguide‐resonator system, which significantly enhances the quality factor (Q$Q$). Benefiting from the high‐Q$Q$ characteristics of quasi‐BICs, a sensitivity‐tunable complex permittivity sensor is developed based on this system, achieving improvements of 93 ...

On the eigenfrequency of a gas bubble in a liquid
, 1997 This investigation concerns free linear gas bubble oscillations in liquids. Of prime interest is the eigenfrequency, and in particular its real part, here named as the transient frequency.

Laser &Photonics Reviews, Volume 20, Issue 11, 5 June 2026.Neural networks can accelerate modeling and inverse design of electromagnetic devices by several orders of magnitude, but usually require large amounts of data to train. This work demonstrates that integrating knowledge about quasinormal modes into the network architecture reduces the required amount of training data significantly, while simultaneously

Robust Linearization and Eigenvalue Analysis of General Complex Constrained Multibody Systems
International Journal of Mechanical System Dynamics, Volume 6, Issue 2, Page 187-203, June 2026.ABSTRACT The derivation of linearized equations and subsequent eigenvalue analysis is the basis for tasks such as frequency‐domain response analysis, control design, and stability assessment for mechanical systems. However, for general multibody systems with redundant or nonholonomic constraints, practical challenges persist in achieving numerically ...

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.ABSTRACT The mechanical characterization of brain tissue in multiple time scales is often limited by inconsistent or contradicting responses when different experiments are used. The main reason for theses discrepancies are variations in the experimental setups, as brain tissue is sensitive to changes in the time and length scale.
