The present research focuses on a detailed facies description and interpretation of five alluvial fans of the Qazvin Plain. Beside the tectonic activity that leads to the localization of the fans on the northern margin of the Qazvin Plain, the climate has a significant role in the occurrence of their facies. The alluvial fans are divided into three facies groups: group 1, group 2, and group 3. ...

BACKGROUND Heatwaves are hot weather events, which breach regional or national thresholds, that last for several days. They are likely to occur with increasing frequency in some parts of the world. The potential consequences were illustrated in Europe in August 2003 when there were an estimated 30,000 excess deaths due to a heatwave. Electric fans might be used with the intention of reducing th...

Many applications of networks of agents, including mobile sensor networks, unmanned air vehicles, autonomous underwater vehicles, involve 100s of agents acting collaboratively under uncertainty. Distributed Partially Observable Markov Decision Problems (Distributed POMDPs) are well-suited to address such applications, but so far, only limited scale-ups of up to five agents have been demonstrate...

The purpose of this paper is to understand greedily solvable linear programs in a geometric way. Such linear programs have recently been considered by Queyranne, Spieksma and Tardella, Faigle and Kern, and Krüger for antichains of posets, and by Frank for a class of lattice polyhedra, and by Kashiwabara and Okamoto for extreme points of abstract convex geometries. Our guiding principle is that ...
