Network sensors consist of sensor nodes in which every node covers a limited area. The most common use ofthese networks is in unreachable fields.Sink is a node that collects data from other nodes.One of the main challenges in these networks is the limitation of nodes battery (power supply). Therefore, the use oftopology control is required to decrease power consumption and increase network acce...

Molodstov introduced soft sets to deal with uncertainties and not clear objects. Researchers developed the relationship between soft sets and information systems. Fuzzification of the notions of soft sets and soft topology have been discussed in the literature. In this paper, we define and establish the topological structures of fuzzy soft semi-open sets and fuzzy soft semi-closed sets. We intr...

Lung macrophages (LM)' are known to differ f rom peri toneal macrophages (PM) in many respects, such as their lysosomal enzymes, metabol ic activity for ene rgy requ i rement , morphology , and function (1-3). We repor t ed that the expression of a glycosphingolipid, asialo GM1, on the cell surface is markedly di f ferent be tween LM and PM (4, 5). In the present paper , we repor t that LM are ...

In December 2007, the Cinemateca Portuguesa (the Portuguese Film Museum) ended a yearlong programme dedicated to ‘national genres’ with a selection of 18 Portuguese fi lms not associated with any particular genre, but with the category of ‘Portuguese cinema’ itself . It seemed an odd choice, even if one took into account the very loose definit ion of ‘f i lm genre’ of the previous months – who ...

Since upper and lower approximations could be induced from the rough set structures, rough sets are considered as approximations. The concept of fuzzy rough sets was proposed by replacing crisp binary relations with fuzzy relations by Dubois and Prade. In this paper, we introduce and investigate some properties of intuitionistic fuzzy rough approximation operators and intuitionistic fuzzy relat...

Semantic similarity measure between concepts is a generic issue for many applications of computational linguistics and artificial intelligence. Information Content (IC) of concept is an important dimension of accessing semantic similarity between two concepts. Recently it has attracted great concern and become a hot topic. The paper gives a general overview of usage of information content in se...
