Wireless sensor networks have been widely considered as one of the most important 21th century technologies and are used in so many applications such as environmental monitoring, security and surveillance. Wireless sensor networks are used when it is not possible or convenient to supply signaling or power supply wires to a wireless sensor node. The wireless sensor node must be battery powered.C...

Entity Resolution, which identifies different descriptions referring to the same real-world entity, is a fundamental stage in data integration process essential for quality analysis. Identities recognition important encounter network as it defines entities of encounters. It usually not problem if unique identifier information, e.g., mobile phone number, available. However, circumstances where a...

a wireless sensor network consists of many inexpensive sensor nodes that can be used toconfidently extract data from the environment .nodes are organized into clusters and in each cluster all non-cluster nodes transmit their data only to the cluster-head .the cluster-head transmits all received data to the base station .because of energy limitation in sensor nodes and energy reduction in each d...

this study presents the effects of project uncertainties on nonlinear time-cost tradeoff (tct) profile of real life engineering projects by the fusion of fuzzy logic and artificial neural network (ann) models with hybrid meta-heuristic (hmh) technique, abridged as fuzzy-ann-hmh. nonlinear time-cost relationship of project activities is dealt with ann models. ann models are then integrated with ...

haraz-ghareh su is one of the seven sub-basins of the caspian basin, located on the southern shores of the caspian sea, and as such, is in danger of water crisis due to absence of proper systematic policy and strategy. in this study, the pressure factors on the haraz-ghareh su water resources were identified using dpsir model. then, the pressure parameters on the freshwater resources in the cas...
