hydrothermal alteration processes are extensively took place on volcanic and pyroclstics of takestan area. existence of abundant, deep fracturing and subvolcanic intrusions are enhanced extend hydrothermal alteration zones. the following alteration zones are determined: propylitic, argillic, advanced argillic and sillicic. there are outcropped and widespread in different size and limit. formati...

In these notes we give a brief introduction to Kolmogorov complexity. The notes are based on the two talks given at KAM Spring School, Borová Lada, 2006.

Introduction: CM chondrites contain minerals that formed by interaction between liquid water and anhydrous minerals [1]. How this process progressed on the parent body is important for understanding how to unravel the effects of aqueous alteration in these meteorites. Studies undertaken to qualify [1] and quantify [2] the extent of alteration found in the CMs resulted in a mineralogic alteratio...

For reservoir operation, maintaining a quasi-natural flow regime can benefit river ecosystems, but may sacrifice human interests. This study took the Qingshitan Reservoir in the Lijiang River as a case, and developed an optimization model to explore a trade-off solution between social-economic interests and nature flow maintenance on a monthly base. The objective function considered irrigation,...
