Energy efficiency and positional accuracy are often contradictive goals. We propose to decrease power consumption without sacrificing significant accuracy by developing an energy-...
802.11-based indoor positioning systems have been under research for quite some time now. However, despite the large attention this topic has gained, most of the research focused o...
Abstract. In this paper we give some applications of weakly Picard operators theory to linear positive approximation operators, to difference equations with deviating argument and...
