Accurate modelling of the low-order secondary resonances in the spin-orbit problem
, 2019 We provide an analytical approximation to the dynamics in each of the three most important low order secondary resonances (1:1, 2:1, and 3:1) bifurcating from the synchronous primary resonance in the gravitational spin-orbit problem.

From Copper Nanoparticles to Alumina Encapsulated Porous Layers With Enhanced Mechanical Stability
Advanced Materials Interfaces, EarlyView.This study analyzes the synthesis‐structure relation of individual Cu nanoparticles and highly porous nanoparticle‐based Cu films using different sputtering‐based nanoparticle sources. The inherent mechanical instability of the films is tackled with Al2O3 encapsulation through atomic layer deposition, enabling 4‐fold increase in critical force in ...

Chirikov Diffusion in the Asteroidal Three-Body Resonance (5,-2,-2) [PDF]
, 2010 The theory of diffusion in many-dimensional Hamiltonian system is applied to asteroidal dynamics. The general formulations developed by Chirikov is applied to the Nesvorn\'{y}-Morbidelli analytic model of three-body (three-orbit) mean-motion resonances ...

Multidirectional Motion Strategy of Miniature Water Surface Robot Actuated by Single Exciter
Advanced Robotics Research, EarlyView.A novel multidirectional motion strategy on the water surface based on a single exciter is proposed, and a single‐exciter single‐plate module is developed for actuation. The driving forces generation mechanism of the module is revealed from the perspective of the asymmetric surface wave field.

Behavior Of Slender Column Subjected To Eccentric Loading
, 2015 This paper focuses on Behavior of slender column su bjected to eccentric loading. Six slender,reinforced concrete columns with slenderness ratio equals to 15;the compressive strength of the concrete were ranged from 60 to 100 MPa. Slender co lumn were subjected to eccentric axial load with load-eccentricity:depth ratio of 0.15.
