In segmented paleorift systems such as the Pripyat–Dnieper–Donetsk aulacogen, which penetrate deep into continent from side of paleoocean margin and most often close here, each segment represents an autonomous structure lithosphere. The presented article shows that tectonic position Pripyat western closing indicated aulacogen was due to a change in intensity syn-rift plate-tectonic processes ex...

Abstract We introduce a novel method for map registration and apply it to transformation of the river Ister from Strabo’s World current in Geodetic System. This leads surprising but convincing result that best coincides with nowadays Tauernbach-Isel-Drava-Danube course not Danube what is commonly assumed. Such supported by carefully designed mathematical measurements resolves all related contro...

После выявления на Кавказе в начале 70-х годов ХХ века тектонических покровов стало понятно, что последовательность нижне(?) и среднепалеозойских пород древнего ядра Большого Кавказа является тектоно-стратиграфической образует аккреционную колонну. Считалось, современном виде она была сформирована главную фазу герцинского орогенеза представлена несколькими системами покровов. В работах кавказск...

The problem of finding an optimal vertex cover in a graph is a classic NP-complete problem, and is a special case of the hitting set question. On the other hand, the hitting set problem, when asked in the context of induced geometric objects, often turns out to be exactly the vertex cover problem on restricted classes of graphs. In this work we explore a particular instance of such a phenomenon...

EDITOR’S NOTE Geopersia is published biannually by the College of Science, University of Tehran, Iran. The College of Science published “Journal of Science”, which covered all fields of basic science, from 1968 to 2010. It was then decided that the College’s journals should be more specialized, and hence publication of Geopersia was launched. Geopersia aims to publish peer-reviewed original...

This is an extended abstract that overviews our cover song identification system as submitted to the MIREX 2008 Audio Cover Song Identification task. The system is developed from our 2007 MIREX submission but including some important modifications and parameter tuning. For time reasons, the present document is just a very early draft version. Further versions will be available soon.

The tectonic map at scale 1:1,750,000 presented in this work shows an update of the existing knowledge main and volcanic structures along Iberian continental margins abyssal plains. morphotectonic trends around Iberia recorded superposed geodynamic processes linked to opening North Atlantic Ocean since Mesozoic evolution Mediterranean Sea during Cenozoic, as well reactivation Hercynian faults f...

Weed management is a major issue in organic farming systems. Although interseeding cover crops is one alternative to herbicides, cover crops often suppress not only weeds but also main crops. Therefore, using cover crops for weed control without adverse effects on main crop growth is important. To verify the effect of cover crops on competition between main crops, cover crops and weeds in snowy...

We introduce the successive Hitting Set model, where the set system is not given in advance but a set generator produces the sets that contain a specific element from the universe on demand. Despite incomplete knowledge about the set system, we show that several approximation algorithms for the conventional Hitting Set problem can be adopted to perform well in this model. We describe, and exper...
