Energy Balance Models and Planetary Dynamics

open access: yes, 2012
We know that planetary dynamics can have a significant affect on the climate of planets. Planetary dynamics dominate the glacial-interglacial periods on Earth, leaving a significant imprint on the geological record.

Modelling planetary dynamics by using the temperature at the core-mantle boundary as a control variable: effects of rheological layering on mantle heat transport [PDF]

open access: yes, 1998
In planetary convection, there has been a great emphasis laid on the usage of the Rayleigh number as a control parameter for describing the vigor of convection.

The topology of non-linear global carbon dynamics: from tipping points to planetary boundaries

open access: yesEnvironmental Research Letters, 2013
We present a minimal model of land use and carbon cycle dynamics and use it to explore the relationship between non-linear dynamics and planetary boundaries.

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

open access: yesAdvanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

In situ, Surface-deployed Distributed Instruments for Planetary Science: Scientific Opportunities and Technology Feasibility

open access: yesThe Planetary Science Journal
In this paper, we assess the scientific promise and technology feasibility of in situ distributed instruments for planetary surface and atmospheric science. A distributed instrument is an instrument designed to collect spatially and temporally correlated

Study on Nonlinear Dynamics Characteristic of Two-stage Planetary Gear Train

open access: yesJixie chuandong, 2020
The translation and torsion coupled strong nonlinear dynamics model of two-stage planetary gear transmission system is established, and the nonlinear factors such as time-varying meshing stiffness, tooth side clearance and meshing error are introduced ...

Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion

open access: yesAdvanced Robotics Research, EarlyView.
This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...

The use of the Mathematica software in the study of planetary dynamics

open access: yes, 2013
This work presents a study on how techniques provided by the algebraic manipulation software Mathematica can be used in planetary dynamics investigations. The discovery of extra-solar planetas orbiting other stars has been one of the major break-throughs

Climate effects of a future net forestation scenario in CMIP6 models

open access: yesnpj Climate and Atmospheric Science
Forestation may reduce temperatures by lowering atmospheric CO2. However, biogeophysical changes from forestation may weaken this cooling. We use twelve Coupled Model Intercomparison Project (CMIP6) models to quantify the biogeochemical (carbon cycle ...
