A Wireless Sensor Network (WSN) is a wireless decentralized structure network consists of many nodes. Nodes can be fixed or mobile. WSN applications typically observe some physical phenomenon through sampling of the environment so determine the location of events is an important issue in WSN. Wireless Localization used to determine the position of nodes. The precise localization in WSNs is a co...

Within is a description of both the contents and employment of a knowledge base used for storing event and state lexical semantic information. Of particular focus is an explanation of how the knowledge base is currently used to define thematic roles and to enrich and disambiguate logical forms.

The electrophysiological bases of conflict control in a number interference task was measured in 21 healthy study participants using event-related brain potentials (ERPs). In the number interference task, participants were instructed to ignore the number words meaning and to report the number of the number words. The number words were 'two', 'three', or 'four'. We focused on the differences bet...

climate change has various effects on the quantity of rainfall and warming also is lead to increases in frequency and intensity of droughts by accelerating earth drying up and consequently. it is effective on the curves of severity- duration- frequency of drought (sdf). the purpose of this study is to evaluate the effects of climate change on sdf curves in the future in qareh su basin located i...
