In this paper, we improve the GSM (Global System for Mobile Communications) authentication protocol to reduce the signaling loads on the network. The proposed protocol introduces a notion of the enhanced user profile containing a few of VLR IDs for the location areas where a mobile user is most likely to visit. We decrease the authentication costs for roaming users by exploiting the enhanced us...

Genetic improvement of seed vigour and emergence of yellow-seeded flax (Linum usitatissimum L.) is important to have a good stand establishment, since they are negatively affected by yellow seed colour. This study was conducted to investigate genetic variation, broad-sense heritability and expected genetic response to selection for germination, seed vigour and field emergence. Sixteen genotypes...

nineteen irrigated farms of canola from six cities of khorasan selected to assess the seedling emergence one month after sowing in 2009. soil texture of each farm determined using the hydrometer method. the results showed that weather conditions of sowing areas had no significant effect on emergence of oilseed rape. with increasing the temperature (within the range of 19.5 to 21.5 ˚c) emergence...

Given a large network and a query node, finding its top-k similar nodes is a primitive operation in many graphbased applications. Recently enhancing search results with diversification have received much attention. In this paper, we explore an novel problem of searching for top-k diversified similar nodes in attributed networks, with the motivation that modeling diversification in an attributed...

Introduction The rapid expansion of WWW has unobtrusively influenced humans' socio-economical life patterns in the last decade.
