The Development of high fidelity linearized J2 models for satellite formation flying control [PDF]
The inclusion of the linearized J2 effect in the Hill equations of relative motion gives greater insight into satellite formation flying dynamics, and the opportunity to investigate alternative feedback control strategies for the station keeping task.

How frequent is natural cloud seeding from ice cloud layers ( < −35 °C) over Switzerland? [PDF]
Clouds and cloud feedbacks represent one of the largest uncertainties in climate projections. As the ice phase influences many key cloud properties and their lifetime, its formation needs to be better understood in order to improve climate and weather ...

Study and Analysis of Landslide Potential Us-ing Numerical Modeling (A Case Study: Ghaen-Afin Roadway in Southern Khorasan) [PDF]
Steep slopes developed on the loose ground, either natural or artificial, are prone to landslide phenomena. During con-struction activities for the development of new Qaen-Afin road in South Khorasan and adjacent to Ravoshk village, a sudden landslide ...
