A fabrication process for electrostatic microactuators with integrated gear linkages [PDF]

open access: yes, 1997
A surface micromachining process is presented which has been used to fabricate electrostatic microactuators. These microactuators are interconnected with each other and linked to other movable microstructures by integrated gear linkages.

Forced Response Analysis of Dynamic Systems With Inertia Nonlinearity by Applying the Multiharmonic Balance Method

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.
ABSTRACT Nonlinear mechanical vibrations under harmonic forcing can be well approximated by Fourier series. For a finite number of harmonics, the error is minimized over one period of vibration. This technique, known as multiharmonic balance method (MHBM), is today widely used in academics as well as industrial applications, e.g., for friction‐damped ...

Structural and magnetic properties of isovalently substituted multiferroic BiFeO3: Insights from Raman spectroscopy [PDF]

open access: yes, 2012
Raman spectra, supplemented by powder x-ray diffraction and magnetization data of isovalently A- and B-site substituted BiFeO3 in the Bi1−xLaxFeO3 (0≤x≤1), Bi1−xTbxFeO3 (0≤x≤0.2), and Bi0.9Sm0.1Fe1−xMnxO3 (0≤x≤0.3) series, are presented. A good agreement

A COMPARATIVE CALCULATION OF CYCLOID DRIVE EFFICIENCY

open access: yes, 2020
Determining cycloid drive efficiency is a very complex task that in the most cases requires theoretical analysis, numerical calculation, computational simulations and experimental research. The paper aims to compare the results obtained based on two so far the most recognized and acceptable theoretical models (Malhotra model and Kudryavtsev model).

Kinetic Structure of an Interplanetary Shock Observed at Two Heliocentric Longitudes

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Collisionless shocks convert bulk flow energy into heat, electromagnetic fields, and non‐thermal particle populations. Recent studies suggest that downstream magnetic oscillations could play an important role in ion‐scale energy dissipation at low‐Mach‐number shocks; however, the specific shock and plasma parameters involved remain poorly ...
