the gravimetric method is one of the most effective ways for the detection of subsurface structures such as tunnels, faulting, mineral deposits with the required density difference, especially in areas with rough topography and tectonized formations. it is possible to provide a more suitable model for better interpretation of the gravity anomaly. inverse modeling of gravity data is the most eff...

We have developed a steady-state energy balance model of the solar corona, which calculates coronal magnetic field structure and thermodynamics from a photospheric magnetogram. Our method involves a solution of energy and momentum equations along individual coronal loops, allowing for flows, gravity, non-uniform heating, and cross-sectional area variations. The model yields predicted plasma emi...

A combination of multiple gravity-assist and impulsive ∆V maneuvers are often utilized for interplanetary missions to outer planets, such as NASA’s Galileo and Cassini missions. Such complex interplanetary missions often require the optimization of more than 20 variables, making brute force and traditional NLP methods difficult, if not impossible. In this paper a genetic algorithm, which utiliz...

Hot super-Earths are exoplanets with masses ≤ 10M⊕ and orbital periods≤ 20 days. Around 8 hot super-Earths have been discovered in the neighborhood of solar system. In this lecture, we review the mechanisms for the formation of hot super-Earths, dynamical effects that play important roles in sculpting the architecture of the multiple planetary systems. Two example systems (HD 40307 and GJ 436) ...

In 2004, at the Gravity, Geoid and Space Missions (ggsm04) conference in Porto, Portugal, a joint meeting of the International Association of Geodesy (IAG) Working Groups on Inverse Problems and Global Optimization and Satellite Gravity Theory took place. It was then recognized that gravity modelling from satellite, airborne and terrestrial data, and today’s application of gravity models in rel...
