On the Dependence of Planetary Spin on Mass [PDF]
American Journal of Astronomy and Astrophysics, 2014 The recent direct spectroscopic observation of the spin of the young gas giant exoplanet ? Pictoris b was a powerful clue as to the general validity of the trend of the planetary spin with the mass even outside the Solar System. Nevertheless, the spin-mass relationship, which looks like to hold irrespective of the planet composition and radius, is ...

Advanced Robotics Research, EarlyView.A novel carbon fiber reinforcement for dielectric elastomer actuators enhances actuation force while decoupling electromechanical performance from the actuator's aspect ratio. Unlike conventional fiber reinforcements, it enables a uniform planar stretch state along the entire actuator.

The Small Frontier: Trends Toward Miniaturization and the Future of Planetary Surface Rovers
ActuatorsThe robotic exploration of space began only five decades ago, and yet in the intervening years, a wide and diverse ecosystem of robotic explorers has been developed for this purpose. Such devices have greatly benefited from miniaturization trends and the

Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion
Advanced 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 ...

Theory of planet formation and comparison with observation
EPJ Web of Conferences, 2011 The planetary mass-radius diagram is an observational result of central importance to understand planet formation. We present an updated version of our planet formation model based on the core accretion paradigm which allows us to calculate planetary ...

ANALYSIS OF SELF – GRAVITATING PLANETARY SATELLITES IN THE SOLAR SYSTEM
Odessa Astronomical Publications, 2016 As of today there have been more than 180 planetary satellites discovered in the Solar system, and the number of outer moons found continues to grow. Most of those natural satellites have insufficient mass and are able to retain their shape only due to ...
