Distribution problems deal with distribution from a number of sources to a number of destinations. Each source offers amounts of goods, while each destination demands quantities of these goods. The object is to find the cheapest transporting schedule that satisfies demand without violating...

The aim of this paper is to analyze the suitability of representing linguistic information by means of 2–tuples and its comparison with the methodology of expertons for handling problems of decision–making in uncertainty environments. In these cases, the information is expressed in the form...

We study the statistical properties of SIR epidemics in random networks, when an epidemic is defined as only those SIR propagations that reach or exceed a minimum size sc. Using percolation theory to calculate the average fractional size 〈MSIR〉 of an epidemic, we find that the strength of...

This work reports the magnetic properties of sputtered permalloy (Ni<Subscript>80</Subscript>Fe<Subscript>20</Subscript>) multilayers grown changing the anisotropy direction 90° in successive layers. Magnetic measurements show how the saturating field can be controlled by the thickness ratio between different anisotropy layers and how the...</subscript></subscript>

We study the transport properties of model networks such as scale-free and Erdös-Rényi networks as well as a real network. We consider few possibilities for the trnasport problem. We start by studying the conductance G between two arbitrarily chosen nodes where each link has the same unit...
