Applications of cosmological perturbation theory [PDF]
, 2011 PhDCosmological perturbation theory is crucial for our understanding of the universe. The linear theory has been well understood for some time, however developing and applying the theory beyond linear order is currently at the forefront of research in

Analytical and numerical analysis of nonisothermal compressible rarefied gas flow between parallel plates [PDF]
Theoretical and Applied Mechanics, 2023 When dimensions of the flow domain become small, such as in the micro-electro-mechanical systems (MEMS) and nano-electro-mechanical systems (NEMS), rarefaction effects become more prominent.

Flexural-Torsional Galloping of Prismatic Structures with Double-Symmetric Cross-Section [PDF]
Journal of Applied and Computational Mechanics, 2021 The linear galloping of prismatic structures having double-symmetric cross-section, subjected to steady wind flow acting along a symmetry axis, is investigated. The continuous system is reduced to a three degree-of-freedom system via a Galerkin approach.

Homotopy perturbation method coupled with the enhanced perturbation method [PDF]
Journal of Low Frequency Noise, Vibration and Active Control, 2018 The enhanced perturbation method is used to improve a governing equation to a higher order, followed by the classic perturbation method. This paper adopts the basic idea of the method to construct a homotopy equation with a higher order. The results show that this modification of the homotopy perturbation method leads to a very high accuracy of the ...

scPerturb: harmonized single-cell perturbation data
bioRxiv, 2023 Recent biotechnological advances led to growing numbers of single-cell perturbation studies, which reveal molecular and phenotypic responses to large numbers of perturbations. However, analysis across diverse datasets is typically hampered by differences

Influence of the Motion of a Spring Pendulum on Energy-Harvesting Devices
Applied Sciences, 2021 Energy harvesting is becoming more and more essential in the mechanical vibration application of many devices. Appropriate devices can convert the vibrations into electrical energy, which can be used as a power supply instead of ordinary ones. This study
